[032] The following description of the main embodiments of the invention is made with reference to the accompanying figures, in which the same reference numbers denote identical or similar elements.
[033] In the description, the geometric axis X represents substantially the longitudinal direction of the cable, while the geometric axis Y is perpendicular to the geometric axis X; for example, the Y geometric axis can represent the rotating geometric axis of the blade cartridge. DESCRIPTION OF FIRST ACHIEVEMENT
[034] Figure 1 illustrates a razor blade 101 according to the first embodiment of the invention, which comprises a handle 102, a blade cartridge 103, a cover 104 and an actuation button 105. The handle 102 can be elongated, which comprises an elongated cable body 102A. The cable body 102A can include a handle portion. The cable body 102A can additionally be produced from low cost material, such as plastic material. Alternatively, the cable body 102A can be produced from any other suitable material, such as metal. The cable body 102A, according to the present invention, can comprise the smallest number of components possible. The cable body 102A can be produced as a part. The cable body 102, the cover 104 and / or the button 105 can comprise at least one finger rest area. Finger rest areas can be produced, for example, from rubber or the like.
[035] The razor blade 101 is adapted for use with disposable razor cartridges. The razor blade 101 can be provided with an arm assembly comprising two arms 106, as can be seen in Figure 2. The arms 106 are adapted to engage and disengage the blade cartridge 103. For example, the two arms 106 can be movable between a resting position, in which the cartridge 103 is attached to the cable 102, and a release position, in which the two arms 106 are closer together, thereby releasing the blade cartridge 103 from the cable 102.
[036] The cartridge 103 can be provided with a pair of rings 103A. The rims 103A can be adapted to engage with a pair of shield bearings 119A provided in the arms 106. The shield bearings 119A and rims 103A are preferably adapted to support the rotating movement of the cartridge 103 around the Y-axis. Alternatively, the arms 106 can be compatible with an intermediate structure attached to the cartridge 103. The arms 106 can then engage and disengage with the intermediate structure, or both the cartridge 103 and an intermediate structure.
[037] When moving from the resting position towards the release position, an elastic return force is applied to the two arms 106, so that the arms 106 are elastically inclined towards the resting position. In a possible embodiment, the elastic return force can be represented by an elastic member 107 that interconnects the arms 106. The elastic member 107 pushes both arms 106 away from each other, thereby returning both to the resting position . Alternatively, more than one elastic component can be incorporated into the cable 102, where each elastic component applies a return force to at least one of the arms 106.
[038] The actuation button 105 shown in Figures 1 to 4 of the attached figures is movably mounted on the cable body 102A. The actuation button 105 is adapted to be movable between an elevated position and a compressed position. The actuation button 105 cooperates through the cam action with the pair of arms 106, so that, by pressing the actuation button 105 in the compressed position, the arms 106 are moved closer to the release position, disengaging , thus, of the cartridge 103. When the actuation button 105 is released by a user, the pair of arms 106 is elastically inclined to the resting position and, simultaneously, by means of the cam action, the pair of arms 106 forces the actuation button 105 back to the raised position. A detailed description of the locking and releasing mechanism will be provided below.
[039] Advantageously, the actuation button 105 can comprise a substantially spherical part. The substantially spherical part may comprise any portion of a sphere, for example, a half sphere. Preferably, the substantially spherical part is visible to a user. Alternatively, the actuation button 105 itself can have a substantially spherical shape as shown in Figures 1 to 4. The substantially spherical actuation button 105 can be produced in such a way that it adds weight to the distal part of the cable 102. With a substantially spherical actuation 105, the production process of the actuation button 105, as well as the entire locking and releasing mechanism is simplified, which makes the shaver assembly less expensive. An advantage of the substantially spherical actuation button 105 is that the sphere is symmetrical and easy to mold. The symmetrical shape also simplifies the entire production process, since there is no directional dependence when placing the ball in the cable body 102A during cable assembly 102. The substantially spherical shape of the actuation button 105 is also comfortable for a user when using button 105 as a finger rest area.
[040] In a preferred embodiment, the two arms 106 extend substantially in a common XY plane. The button 105 is mounted on the cable body 102A, so that it can move in a direction substantially perpendicular to the XY plane. The button 105 is preferably restricted in movement within the XY plane and is fixed within the hole 127 of the cover 104. Thus, the button 105 is restricted in movement to the sides of the cable 102 and along the longitudinal direction of the cable 102. The restriction in The movement of the button 105 along the longitudinal direction of the cable 102 within the cable 102 is ensured by blocking the projections 113. In addition, the button 105 is preferably restricted from pivoting. The pivoting restriction can be achieved, for example, by covering the surface of the button 105 with a suitable material, such as rubber or other elastomeric materials, increasing the friction between the button 105 and the rim of the orifice 127. The rubber or another elastomeric material can also serve as a suitable finger rest area. The actuation button 105 can thus also serve as a support area for resting the user's finger during shaving. Therefore, the actuation button 105 provides support for the user's finger, which is close to the blades, so that the movement of the blades on a user's skin can be carried out more conveniently during shaving.
[041] In preferred embodiments, the actuation button 105 can be provided with an external layer adapted to prevent the user's finger from sliding when the finger is resting against the 105 button. Alternatively, the 105 button can be produced from a material, which inherently restricts the sliding movement when in contact with the user's skin. Examples of such a material that prevent sliding movement are elastomeric materials, such as rubber or the like.
[042] The material of the actuation button 105 may have a density different from the material density of the cable body 102A. In this way, the balance of the cable 102 can be improved. Preferably, the difference between the density of the actuating button 105 and the density of the cable body 102A is at least 10% of the density of the cable body 102A.
[043] The material of the actuation button 105 can be chosen from materials with a density greater than the density of a material used to produce the cable body 102A. In a possible embodiment, the button 105 is produced from metal. The weight of the actuation button 105 helps to improve the user's feel during shaving and to improve shaving performance. Such weight in the distal portion of the cable 102 makes the shaving process more natural and convenient, especially when the cable body 102A is molded from low cost lightweight material, such as plastic material. The additional weight placed on button 105 is close to the blades. Therefore, the balance of cable 102 during use can be improved.
[044] It is taken into account that the additional weight of the actuation button 105 is less than the elastic return force exerted by the elastic portion, for example, the elastic member 107, of the two arms 106. This is in order to prevent release unexpected spontaneous occurrence of cartridge 103 merely by the weight of button 105 without a user actually pushing button 105. This provision also ensures that actuation button 105 can be moved back to the raised position, when arms 106 are elastically tilted into position of rest.
[045] Figure 2 shows the cable locking and releasing mechanism 102 according to the first embodiment of the invention. The locking and releasing mechanism comprises two arms 106, the actuation button 105 and an elastic member 107. The elastic member 107 comprises a return force generation portion 107A. The elastic member 107 further comprises preservation portions 107B. In one embodiment, elastic member 107 is a U-shaped elastic member that wraps around a protective member 115, as shown in Figures 2 to 4. Preservation portions 107B act as stop members. The preservation portions 107B and the protection member 115 prevent the return force generation portion 107A of the elastic member 107 from reaching the point of yield or the final tensile stress exerted on them, where the latter is the point of tension maximum that the material can withstand before being subjected to permanent plastic deformation and the last is the point at which the material breaks. When the actuation button 105 is pressed in the compressed position, the two arms 106 move closer together, thereby releasing the blade cartridge 103 from the cable 102. At the same time, the preservation portions 107B are pushed towards each other , so that they rest against the protection member 115. This prevents the arms 106 from moving closer, thereby stopping in the release position and reducing the risk of the return force generation portion 107A, expanding too much and reaching the yield point or the final tensile stress exerted on them. By such provision, the functionality and durability of the elastic member 107 is improved. The probability of accidentally breaking the elastic member 107 by forcing it too much and causing excessive deformation is reduced. The elastic member is therefore less vulnerable to improper or excessive use and the reliability of the entire shaver is therefore also improved. With protective means, such as protection member 115 and stop members 107B, the life of the shaver can be increased; in addition, user costs spent on shaving are reduced.
[046] Figures 2 to 4 show the two arms 106 which comprise distal parts 119 and proximal parts 117. The distal parts 119 of the two arms 106 can be adapted to engage or disengage from the blade cartridge 103. For example, as shown in Figures 2 to 4, the distal part 119 of the arms is provided with shield bearings 119A. Preferably, the shield bearings are adapted to fit with the rims 103A provided in the cartridge 103. The shield bearings 119A and the rim 103A are preferably adapted to allow the pivoting movement of the cartridge 103 around the Y rotating geometric axis. Alternatives for securing the rotating blade cartridge 103 can be used, such as pins and corresponding or similar holes.
[047] The pair of arms 106 is pivotally mounted on the cable body 102A in relation to the pivot points. The pivot points may be in the form of a pair of pins 111 protruding from the cable body 102A. For example, each of the pins 111 can be fitted in each respective opening of a pair of openings 118 provided in the arms 106 as shown in Figures 3 to 4. The openings 118 are preferably provided substantially in the middle of the length of the turning arms 106 The pair of arms 106 is constructed symmetrically in relation to the geometric axis X. Any alternative solutions that allow the relative pivoting movement between the cable body 102A and the two arms may also be possible.
[048] For example, the pins can be provided in the pair of arms 106 and the corresponding openings can be arranged in the cable body 102A.
[049] In order to allow smooth movement of the proximal parts 117 of the arms 106, there may be a depressed area 120 in the cable body 102A surrounding the proximal parts 117. When returned to the resting position, the distal parts 119 of the two arms 106 can be supported by two resting projections 116 which project on each side of the cable 102. In the resting position, the distal parts 119 can rest against the resting projections 116.
[050] When the button 105 is in the compressed position, it is pressed inside the cable body 102A. For this purpose, there is a hollow cavity 114 in the cable body 102A as shown in Figure 3. In the cavity 114, the actuation button 105 can be conveniently seated when actuated in the compressed position. As the button 105 is pressed from the raised position towards the compressed position inside the cable 102, it is housed in the cavity 114.
[051] The proximal parts 117 of the arms 106 may each comprise an inclined surface 117A. For example, the sloping surfaces 117A are flat. The inclined surfaces 117A are preferably facing each other. When the arms 106 are in the resting position and the button 105 is in an elevated position, there are two side portions of the button 105, which rest against the inclined surfaces 117A. In the raised position, the button 105 is seated between the cover 104 and the inclined surfaces 117A. During actuation of button 105, the proximal parts 117 can be separated by pressing button 105 between them. As the proximal parts 117 are separated, they rotate around the pins 111. Simultaneously, the distal parts 119 move closer, thereby releasing the cartridge 103 from the cable 102.
[052] The sides of the button 105 adjacent to the inclined surfaces 117A are adapted to slide along the inclined surfaces 117A, as the button 105 is actuated. For example, a substantially spherical shape of the button 105 is compatible with angled surfaces 117A as shown in Figures 3 to 4. Alternatively, the triangular shape of the portion of the button 105, which contacts the inclined surfaces 117A, is also possible.
[053] In an alternative embodiment, the arms 106 can be adapted so that the distal parts 119 separate when the cartridge 103 is being released. Consequently, the proximal parts 117 of the arms can move closer during the release of the cartridge 103. The actuation button 105 can be adapted to force the proximal parts 117 together when the button is actuated. The proximal parts 117 can therefore alternatively be provided with inclined surfaces 117A with their faces oriented away from each other. The actuation button 105 may alternatively comprise a recessed portion, for example, of a triangular shape, so that, when the recess 105 is actuated, the recessed portion comes into contact and slides along the inclined surfaces 117A, thereby forcing the same to move closer to each other.
[054] As shown in Figure 3, a set of openings 112 can be provided on cable 102. Openings 112 can engage with a set of corresponding protrusions 124 disposed in cover 104. Cover 104 can preferably be snapped onto a set to set of openings 112 in order to be attached to the cable body 102A. In addition, the cover can be provided with a pair of pockets 122 which must cover the pins 111, around which the pair of arms 106 is rotating. In addition, a pair of posts 125 may be present on the inner side of the cover 104. Each of the pair of posts 125 is preferably fitted between the protective member 115 and one of the arms 106 on the most distal part of the cable body 102A. There may also be a hole in the cover 127 in contiguity with the actuation button 105, so that the button 105 is restricted to side-by-side movement. In case the actuation button 105 has a substantially spherical shape, the orifice 127 has a circular shape. Preferably, orifice 127 has a diameter smaller than the diameter of button 105. In the preferred embodiment, button 105 is retained within cable body 102A. In addition, button 105 may project outwardly through hole 127 in cover 104.
[055] Preferably, the cartridge 103 is allowed to rotate around the geometric axis Y. The cable 102 is provided with a return means adapted to return the cartridge 103 to a neutral position when the cartridge 103 is rotated. Cartridge 103 is retained in cable 102 by shield bearings 119A. Shield bearings 119A are adapted to engage with rings 103A provided in cartridge 103. Rings 103A and shield bearings 119A allow cartridge 103 to rotate about the Y axis during shaving. Other means of rotation, which allow the cartridge 103 to rotate around the geometric axis Y, are also possible, for example, the pins provided in the arms 106 and the corresponding holes arranged in the cartridge 103.
[056] In a preferred embodiment, the protective member 115 cooperates with stop members 107B in order to prevent the return force generating portion 107A of the elastic member 107 from reaching the point of performance or the final tensile stress exerted on the same. In addition, the protective member 115 preferably surrounds the return means for returning the rotating cartridge 103 to a neutral position. Therefore, the protective member 115 serves as a multifunctional element, the number of components included in the cable locking and releasing mechanism 102 is reduced and the production process of the cable 102 is simplified. The protective member 115 can be molded as a part of the cable body 102A. The protection member 115 can be molded in the most distal part of the cable 102, next to the cartridge 103. The protection 115 is preferably on the geometric axis X of the cable 102.
[057] The protective member 115 can accommodate any means for returning the cartridge 103 to a neutral position known in the art. According to the embodiment of the present invention, the return means can be a combination of a pusher 108 and a spring 109. The spring 109 can generate the elastic force required to return the cartridge to a neutral position. The pusher 108 preferably cooperates with a corresponding cam surface 110 of the cartridge 103. The pusher 108 can be located inside the guard 115. Preferably, pusher 108 is covered with cover 104, so that pusher 108 is restricted to movement in all directions different from that along the geometric axis X. The pusher 108 is preferably adapted to reciprocate within the guard 115. For this purpose, the pusher 108 can be provided with at least one projection 108A. For example, pusher 108 comprises two projections 108A provided on opposite sides of pusher 108. In a preferred embodiment, such a projection 108A fits within a groove 115A provided inside the guard 115. Preferably, cover 104 is also provided with a groove 126, in which the other projection 108A is located during movement of the pusher 108. DESCRIPTION OF SECOND ACHIEVEMENT
[058] Illustrated in Figure 5 is a razor blade 201, according to the second embodiment of the invention, comprising a handle 202, a blade cartridge 203, a cover 204 and an actuation button 205. The handle 202 may have an elongated cable body 202A comprising an elongated handle portion. The cable body 202A can be additionally produced from low cost material, such as plastic material.
[059] Alternatively, the cable body 202A can be produced from any other suitable material, such as metal. The cable body 202A according to the present invention comprises the smallest possible components. Preferably, the cable body 202A is produced as one piece. The cable body 202A, the cover 204 and / or the button 205 can comprise at least one finger rest area. Finger rest areas can be produced, for example, from rubber or the like.
[060] The razor blade 201 is adapted for use with disposable razor cartridges. The razor blade can be provided with an arm assembly comprising two arms 206 and a connecting portion 214, as shown in Figure 6. The arms 206 are adapted to engage and disengage the blade cartridge 203. For example, the two arms 206 can be moved between a resting position, where the cartridge 203 is attached to the handle 202, and a release position, where the two arms 206 are closer together, thereby releasing the blade cartridge 203 of cable 202.
[061] The 203 cartridge can be provided with a pair of rings 203A. Rims 203A can be adapted to engage with a pair of shield bearings 206A provided on arms 206. Shield bearings 206A and rings 203A are preferably adapted to support the rotating movement of cartridge 203 around the Y-axis. the arms 206 can be compatible with an intermediate structure attached to the cartridge 203. The arms 206 can then engage and disengage with the intermediate structure, or both the cartridge 203 and an intermediate structure.
[062] When moving from the resting position towards the release position, an elastic return force is applied to the two arms 206, so that the arms 206 are elastically inclined towards the resting position. In a possible embodiment, the elastic return force can be generated by elastic connections between the pair of arms 206 and a connecting portion 214. For example, the pair of arms 206 and the connecting portion 214 can be connected via these connections elastic. The pair of arms 206, the elastic connections and the connection portion 214 can be produced as a single piece. In a possible embodiment, the pair of arms 206 is produced from elastic material. The pair of arms 206 can be directly connected to the connection portion 214, without the presence of elastic connections. In that case, the elastic return force can be generated by the arms 206 themselves. The arms 206 can comprise joints 207 that generate the return force. For example, the joints 207 are located at points where the arms 206 protrude from the connecting portion 214, as shown, for example, in Figure 6. Preferably, the connecting portion 214 and the pair of arms 206 extend in the plane XY. The arms 206 are movable between the resting position, where the arm 206 engages the cartridge 203, and the release position, where the arms 206 disengages the cartridge 203. The joints 207 can be adapted to generate an elastic return force . When the two arms 206 are in the release position, the joints 207 push both arms 206 away from each other, thereby returning them to the resting position.
[063] The actuation button 205 shown in Figures 5 to 6 of the attached figures is movably mounted on the cable body 202A. The actuation button 205 is adapted to be movable between an elevated position and a compressed position. The actuation button 205 cooperates by means of the cam action with the pair of arms 206, so that, by pressing the actuation button 205 in the compressed position, the arms 206 are moved closer to the release position. The 203 cartridge is thus disengaged. When the actuation button 205 is released by the user, the pair of arms 206 is elastically tilted to the resting position. Simultaneously, by means of the cam action, the pair of arms 206 forces the actuation button 205 back to the elevated position. A more detailed description of the release mechanism is provided below.
[064] Advantageously, the actuation button 205 can comprise a substantially spherical part. The substantially spherical part may comprise any portion of a sphere, for example, a half sphere. Preferably, the substantially spherical part is visible to a user. Alternatively, the actuation button 205 itself can be substantially spherical in shape, as shown, for example, in Figure 6. As a possible embodiment, the actuation button 205 can be produced in such a way that it adds weight to the distal part of the cable 202. With a substantially spherical button 205, the production process of the actuation button 205, as well as the entire locking and releasing mechanism, is simplified, which makes the shaver assembly less expensive. An advantage of a substantially spherical actuation button 205 is that the sphere is symmetrical and easy to mold. The symmetrical shape also simplifies the entire production process, since there is no directional dependency when placing the ball in the cable body 202A during cable assembly 202. The substantially spherical actuation button 205 is also comfortable for a user when button 205 is used as a finger rest area.
[065] In a preferred embodiment, the two arms 206 extend substantially in a common XY plane. The button 205 is mounted on the cable body 202A, so that it can move in a direction substantially perpendicular to the XY plane. The button 205 is preferably restricted to movement within the XY plane being fixed within the hole 227 of the cover 204. In this way, the button 205 is restricted to movement on the sides of the cable 202 and along the longitudinal direction of the cable 202. Additionally, the button 205 can be restricted to rotating movement. The pivoting restriction can be achieved, for example, by covering the surface of the button 205 with a suitable material, such as rubber or other elastomeric materials, increasing the friction between the button 205 and the rim of the orifice 227.
[066] Rubber or other elastomeric material can also serve as a suitable finger rest area. The actuation button 205 can also serve, in this way, as a support area to rest the user's finger during shaving. Therefore, the actuation button 205 provides support for the user's finger, which is close to the blades, so that the movement of the blades on a user's skin can be carried out more conveniently during shaving.
[067] In preferred embodiments, the actuation button 205 can be provided with an external layer adapted to prevent the slide of a user's finger when resting against the 205 button. Alternatively, the 205 button can be produced from a material, which inherently restricts the sliding movement when in contact with the user's skin. Examples of such a material that prevent sliding movement are elastomeric materials, such as rubber or the like.
[068] The material of the actuation button 205 may have a different density than the material of the cable body 202A. In this way, the balance of the cable 202 can be improved. Preferably, the difference between the density of the actuation button 205 and the density of the cable body 202A is at least 10% of the density of the cable body 202A.
[069] The material of the actuation button 205 can be chosen from materials with a density greater than the density of a material used for the production of the 202A cable body. In a possible embodiment, the button 205 is produced from metal. The weight of the 205 actuation button helps to improve the feel of the user during shaving and to improve shaving performance. Such weight in the distal portion of the cable 202 makes the shaving process more natural and convenient, especially when the cable body 202A is molded from low cost lightweight material, such as plastic material. The additional weight placed on the 205 button is close to the blades. Therefore, the perception of the blades on the user's skin during the shaving course can be improved.
[070] It is taken into account that the additional weight of the actuation button 205 is less than the elastic return force exerted by the elastic portion, for example, the joints 207, of the two arms 206. This is in order to help avoid the unexpected spontaneous release of the cartridge 203 merely by the weight of the button 205 without a user actually pushing the button 205. This provision also ensures that the actuation button 205 can be moved back to the raised position, when the arms 206 are elastically tilted to the resting position.
[071] As a possible embodiment, there is a connecting portion 214 movably mounted on the cable body 202A. The connecting portion 214 can be adapted for sliding movement along the geometric axis X of the cable 202. Preferably, the connecting portion 214 is adapted to slide in a direction away from the cartridge 203.
[072] The connecting portion 214 may additionally include a cavity 214A shaped so that the actuation button 205 engages in the cavity 214A when the actuation button 205 is in the compressed position. In the cavity 214A, the actuation button 205 can be conveniently seated when actuated in the compressed position. As the button 205 is pressed from the raised position towards the compressed position inside the cable 202, it is housed in the cavity 214A.
[073] According to another embodiment, there is a pair of arms 206 that protrude outwardly from the connection portion 214. For example, the arms 206 can project in one direction towards the cartridge 203. The arms 206 can extend preferentially symmetrically to the geometric axis X. In the resting position, the arms 206 can extend so that any portion of the arms 206 located closest to the cartridge 203 is at the same distance or a greater distance from the geometric axis X than the portion located farthest from the cartridge 203. Thus, the arms 206 are diverging from the geometric axis X. Preferably, the pair of arms 206 and the connecting portion 214 are in the XY plane.
[074] Preferably, the cartridge 203 is allowed to rotate around a geometric axis Y. The cable 202 is provided with a return means adapted to return the cartridge 203 to a neutral position when the cartridge 203 is rotated. Cartridge 203 is retained in cable 202 by shield bearings 206A. Shield bearings 206A are adapted to engage with rings 203A provided in cartridge 203. Shield rings 203A and shield bearings 206A allow cartridge 203 to rotate around the Y-axis during shaving. Other means of rotation, which allow the cartridge 203 to rotate around the geometric axis Y, are also possible, for example, the pins provided in the arms 206 and the corresponding holes arranged in the cartridge 203.
[075] In order to allow smooth sliding movement of the connecting portion 214 along the geometric axis X, there may be a depressed area 220 in the cable body 202A surrounding the connecting portion 214. Preferably, the arms 206 are directly connected to the connecting portion 214, so that the connecting portion 214 and the arms 206 slide together. In a preferred embodiment, the arms 206 and the connecting portion 214 are adapted to slide along the geometric axis X in a direction away from the cartridge 203. When returned to the resting position, each of the two arms 206 can be supported by a respective resting projection 216 that projects from each side of the cable 202. In the resting position, the arms 206 rest against the resting projections 216.
[076] As another embodiment, at least one inclined surface 217 can be provided at the connecting portion 214. For example, at least one inclined surface 217 is located close to the edge of the connecting portion 214. At least one inclined surface 217 it can be flat. The at least one sloping surface can project out of the connection portion 214 in a direction perpendicular to the XY plane. Preferably, the at least one inclined surface 217 projects from the connecting portion 214, so that the inclined surface 217 is in contact with the actuation button 205. For example, there is at least one portion on the actuation button 205, which contacts at least one inclined surface 217 of the connecting portion 214. In the elevated position, the button 205 is seated between the cover 204 and at least one inclined surface 217. The at least a portion of the actuation button 205, which contacts at least one inclined surface 217 of the connecting portion 214, can be adapted to slide along at least one inclined surface 217 during actuation of button 205. For example, a substantially spherical shape of the button 205 is compatible with at least one inclined surface 217, as shown in Figure 6. Alternatively, the triangular shape of at least a portion of button 205, which comes in contact with at least an inclined surface 217, would also be possible.
[077] Additionally, the cable 202 can be provided with buoyancy functions 229. For example, the buoyancy functions 229 can project from the resting projections 216 towards the central part of the cable 202, in a direction parallel to the geometric axis Y When the arms 206 are in the resting position, the arms 206 can rest against the thrust functions 229. Preferably, the thrust functions 229 come into contact with the arms 206 substantially in the middle of the length of the arms 206. thrust 229 come into contact, preferably, with that side of the arms 206 that is farthest from the geometric axis X.
[078] When the actuation button 205 is pressed by the user towards the compressed position, the user can slide along at least one inclined surface 217 of the connection portion 214. As the button 205 slides along at least one surface angled 217, the connecting portion 214 is forced by the button 205 to slide along the geometric axis X. For example, the connecting portion 214 is pushed along the geometric axis X in a direction away from the cartridge 203 during actuation of the button 205. Preferably, the connecting portion 214 slides within the depressed area 220.
[079] The connection portion 214 can be attached to the pair of arms 206 by a pair of elastic connections. In a preferred embodiment, when the actuation button 205 is pressed to the compressed position, the connecting portion 214 and the arm 206 slide together along the geometric axis X. Preferably, the connecting portion 214 and the arms 206 slide in one direction away from the 203 cartridge.
[080] The thrust functions 229 can be adapted to move the arms 206 closer together, when the arms 206 and the connecting portion 214 slide together along the geometric axis X. The thrust functions 229 can force in this way , the arms 206 from the resting position to the release position, thereby disengaging the arms 206 from the cartridge 203. For example, in the resting position, the arms 206 can extend so that any portion of the arms 206 located more close to cartridge 203 is at the same distance or at a greater distance from the geometric axis X than the portion located farthest from cartridge 203. Preferably, the thrust functions 229 are located substantially in the middle of the length of the arms 206. Therefore, in the position rest, any portion of the arms 206 closer to the cartridge 203 than the buoyancy functions 229 is also further away from the geometric X axis, compared to the buoyancy functions 229. According to the br steels 206 and the connecting portion 214 slide together in a direction away from the cartridge 203, the corresponding portions of the arms 206 are forced closer by the thrust functions 229. In this way, the thrust functions 229 force the arms 206 towards the release position and cartridge 203 is released.
[081] As a second embodiment, by means of the cam action of the actuation button 205 to the pair of arms 206, the movement of the actuation button 205 from the raised position to the compressed position is connected to the movement of the arms 206 from the resting position to the release position. By pressing the actuation button 205, the arms 206 can move closer to each other, towards the release position, thus releasing the cartridge 203 from the cable 202. Preferably, the two arms 206 are elastically inclined towards the rest position by an elastic force generated by the joints 207. When the button 205 is in the compressed position, the elastic force generated by the joints 207 can raise the actuation button 205 back to the elevated position, when the button 206 is released by a user.
[082] Additionally, as shown in the embodiment of Figure 8c, cable 202 may include a spring 242 positioned close to the proximal side of the connection portion 214. More particularly, the spring 242 may be located between the proximal side of the connection portion 214 and a corresponding adjacent wall of the depression area 220. The spring 242 can be partially embedded in the proximal wall of the depression area 220 next to the proximal side of the connection portion 214. As the connection portion 214 is slid away from the cartridge 203 during the actuation of the actuation button 205, the connection portion presses the spring 242 against the proximal wall of the depressed area 220, thereby increasing the elastic tension within the spring 242. Therefore, the spring 242 can additionally support the force of return generated by the joints 207 when the actuation button 205 is close to being raised to the elevated position.
[083] In an alternative embodiment, the pair of arms 206 may be closer in the resting position than in the release position. For example, when the actuation button 205 is actuated, the arms 206 are forced away to the release position, in this way, the cartridge 203 is released.
[084] In a possible embodiment, a protection member 215 can be provided in the cable body 202A. The protective member 215 can be molded as a part of the cable body 202A. Preferably, the protection member 215 is molded in the most distal part of the cable 202, next to the cartridge 203. The protection 215 is preferably on the geometric axis X of the cable 202.
[085] In a preferred embodiment, the guard member 215 surrounds the return means for returning the rotating cartridge 203 to a neutral position. The protective member 215 can accommodate any means for returning the cartridge 203 to a neutral position known in the art. According to the embodiment of the present invention, the return means can be a combination of a pusher 208 and a spring 209. The spring 209 can generate the elastic force required to return the cartridge 203 to a neutral position. Pusher 208 preferably cooperates with a corresponding cam surface 210 of cartridge 203. Pusher 208 can be located within guard 215. Preferably, pusher 208 is covered with cover 204, so that pusher 208 is restricted to movement in all directions different from that along the geometric axis X. The pusher 208 is preferably adapted to reciprocate within the guard 215. For this purpose, the pusher 208 can be provided with at least one projection 208A. For example, pusher 208 comprises two projections 208A provided on opposite sides of pusher 208. In a preferred embodiment, such a projection 208A fits within a groove 215A provided inside protection 215. Preferably, cover 204 is also provided with a groove, in which the other projection 208A is located during movement of the pusher 208.
[086] In a preferred embodiment, the arms 206 are provided with stop members 228. For example, the stop members 228 ensure that the two arms 206 do not get too close to each other when the arms 206 are moved to the position of release. Stop members 228 rest against a guard member 215, as arms 206 are closing towards each other towards the release position. The joints 207 are thus prevented from a sudden overload, which can lead to the rupture of the joints 207. The protective member 215 and the stop members 228 prevent the joints 207 from reaching the performance point or the tensile stress end exerted on them, where the latter is the point of maximum stress that the material can withstand before being subjected to permanent plastic deformation and the latter is the point at which the material breaks. By providing the arms 206 of the stop members 228, the arms 206 are stopped in the release position, thereby reducing the risk of the joints 207 reaching too far and reaching the point of performance or the final tensile stress exerted on the same. By this provision, the functionality and durability of the 207 joints are improved. The likelihood of accidentally breaking joints 207 by forcing them too much and causing excessive deformation is reduced. The 207 joints are thus less vulnerable to improper or excessive use and the reliability of the entire shaver is therefore also improved. With protective means, such as protection member 215 and stop members 228, the life of the shaver can be increased; in addition, user costs spent on shaving are reduced.
[087] Therefore, the protection member 215 serves as a multifunctional element. Consequently, the number of components included in the cable locking and releasing mechanism 202 is reduced and the production process of cable 202 is simplified.
[088] In addition, stop functions 228 can be adapted so that they do not allow arms 206 to move to the release position in case cartridge 203 is pulled out. For this purpose, safety functions 228A can be arranged on the sides of the distal part of protection 215. Safety functions 228A can project out of protection 215 towards the sides of cable 202. Stop functions 228 are secured by safety functions 228A, so that stop functions 228 are prevented from moving towards cartridge 203. Therefore, cartridge 203 is more effectively prevented from accidental release and user safety is increased.
[089] In a preferred embodiment, the two arms 206, the connecting portion 214 and the stop members 228 are produced from plastic material. The pair of arms 206 can be directly connected to the connection portion 214, without the presence of elastic connections. In this case, the elastic return force can be generated by the arms 206 themselves.
[090] The arms 206 can comprise the joints 207 that generate the return force.
[091] As pictured in Figures 8a to 8b, a set of openings 212 can be provided on cable 202. Openings 212 can engage with a set of corresponding protrusions 224 disposed in cover 204. Cover 204 can preferably be fitted by pressing in a set of openings 212, in order to be fastened to the cable body 202A. There may also be a hole 227 in the cover 204 in contiguity with the actuation button 205, so that the button 205 is restricted to movement side by side. In case the actuation button 205 is substantially spherical in shape, the orifice 227 has a circular shape. Preferably, orifice 227 has a diameter smaller than the diameter of button 205. In the preferred embodiment, button 205 is retained within cable body 202A. In addition, button 205 may project outwardly through hole 227 in cover 204. DESCRIPTION OF THE THIRD ACHIEVEMENT
[092] A shaver 301, according to another embodiment of the invention, is shown in Figure 9. The shaver 301 comprises a handle 302, a cartridge 303 and an actuation button 305. The button 305 additionally comprises a substantially spherical part 305A fixed on the 305 button.
[093] The cable 302 may comprise an elongated cable body 302A, which includes an elongated handle portion. The cable body 302A can additionally be produced from low cost material, such as plastic material. Alternatively, the cable body 302A can be produced from any other suitable material, such as from metal. The cable body 302A, according to the present invention, preferably comprises the smallest number of components. Preferably, the cable body 302A is produced as one piece. The cable body 302A and / or the button 305 can comprise at least one finger rest area. Finger rest areas can be produced, for example, from rubber or the like.
[094] The distal part of the handle 302, according to the third embodiment of the present invention, is illustrated for example in Figure 10. The locking and releasing mechanism is adapted to be engaged and disengaged releasably from the blade cartridge 303. The cable 302 is provided with an arm assembly comprising a pair of arms 306. The cartridge 303 is pivotally mounted on the pair of arms 306. The arms 306 are movable between the resting position, when the cartridge 303 is engaged in the cable 302, and the release position, when cartridge 303 is disengaged from cable 302. As shown in Figure 10, arms 306 are provided with shield bearings 306A through which cartridge 303 is mounted on cable 302. In position rest, the shield bearings 306A are engaged with rims 303A provided in the cartridge 303. The rings 303A and the shield bearings 306A allow for a rotary movement of the cartridge 303 around the rotating geometric axis Y. Any alternative means for securing the rotary blade cartridge 303 can be used, such as pins and corresponding or similar holes.
[095] Alternatively, the arms 306 can be compatible with an intermediate structure attached to the cartridge 303. The arms 306 can then engage and disengage with the intermediate structure, or both the cartridge 303 and an intermediate structure.
[096] The pair of arms 306 is adapted to cooperate with the actuation button 305. Upon actuation of the actuation button 305, the two arms 306 are moved closer to the release position by means of the cam action between the button actuation 305 and the pair of arms 306. Advantageously, the actuation button 305 can comprise a substantially spherical part 305A. The substantially spherical part 305A can comprise any portion of a sphere, for example a half sphere. Preferably, the substantially spherical part 305A is visible to a user. The substantially spherical part 305A is preferably positioned so that the user's finger comes into contact with it when pressing the 305 button. The production process of the substantially spherical part 305A is simpler and faster and with less production costs than than the production process of other more complex parts. The substantially spherical shape is also comfortable for a user when using the substantially spherical part 305A as a finger rest area.
[097] The material of the substantially spherical part 305A may have a density different from the density of the material of the cable body 302A. In this way, the balance of the cable 302 can be improved. Preferably, the difference between the density of the substantially spherical part 305A and the density of the cable body 302A is at least 10% of the density of the cable body 302A.
[098] The substantially spherical part 305A can be produced in such a way that it adds weight to the distal part of the cable 302. More particularly, the substantially spherical part 305A can be produced from material with a density greater than the density of the material used for produce the 302A cable body. For example, the substantially spherical part 305A can be produced from metal. The actuation button 305 can therefore serve multiple functions. It releases the blade cartridge 303. It also provides additional weight to the distal part of the cable 302.
[099] The substantially spherical part 305A of the actuation button 305 with added weight helps to improve the feel of the user during shaving and to improve shaving performance. The additional weight in the distal portion of the cable 302 makes the shaving process more natural and convenient, especially when the cable body 302A is molded from low cost lightweight material, such as plastic material. The additional weight placed on button 305 is close to the blades. Therefore, the perception of the blades on the user's skin during the shaving course can be improved.
[0100] The actuation button 305 and / or the substantially spherical part 305A of the actuation button 305 can serve as a support area for resting the user's finger. Therefore, button 305 and / or the substantially spherical part 305A of button 305 can be coated with rubber or other elastomeric material to prevent a user's finger from sliding when the finger is resting against button 305. Alternatively, button 305 can be produced from a material, which inherently restricts the sliding movement when in contact with the user's skin. Examples of such a material that prevent sliding movement are elastomeric materials, such as rubber or the like.
[0101] When the cartridge 303 is released from the cable 302, the arms 306 are flexed to be placed closer together. The cartridge 303 can therefore be disengaged from the shield bearings 306A and removed or replaced. For this reason, each arm 306 comprises a receptacle 330. The receptacles 330 are provided on the front surface of each respective arm 306. The receptacles 330 can be non-linear in shape. For example, receptacles 330 may have a shape substantially similar to the beam. The receptacles 330 are adapted to receive pins 337 provided in the button 305. Preferably, the arms 306 are positioned symmetrically with respect to the geometric axis X in the cable 302.
[0102] Between the arms 306, a platform 331 is positioned.
[0103] The platform serves multiple purposes. It provides support for pusher 308. Additionally, it locks button 305 in position and helps prevent disengagement of button 305. Platform 331 is preferably in the general shape of a prism. Preferably, the walls of the platform 331 which are adjacent to the arms 306 are parallel to the longitudinal geometric axis of the shaver.
[0104] The 331 platform comprises a front wall, in which the front wall is oriented towards the button 305. The front wall of the platform comprises a 331A rail. Rail 331A is adapted to receive one of the 308A orientation projections provided on pusher 308. Rail 331A then helps guide pusher 308 to linearly reciprocate, which reduces the risk of pusher 308 being displaced or disoriented in a wrong direction. Therefore, the risk of damage to pusher 308 is reduced and the function of cartridge 303 that returns to its resting position is enhanced.
[0105] The arms 306 and the platform 331 are separated from each other by non-linear slots 332. The non-linear slots 332 are provided between the platform 331 and each respective arm 306. Each of the non-linear slots 332 comprises a portion which defines a linear part 333. The linear part 333 is adapted to cooperate with the button 305, namely, with locators 338 provided in the portion of the button 305 that corresponds to the distal part of the cable body 302A.
[0106] Below platform 331, a slit 334 is formed. The slot has a substantially rectangular shape. Slit 334 can be stretched in one direction. Preferably, this direction is parallel to the longitudinal axis of the shaver 301. Preferably, the walls of the slit 334 parallel to the longitudinal axis of the shaver 301 are parallel to each other and also to the side walls of the platform 331. The side walls of the slot 334 can be provided substantially in a line with the side walls of the 331 platform. Preferably, the side walls form two longitudinal edges that form a pair of opposite rails. Preferably, the rails are adopted to receive flexible hooks 339 from button 305.
[0107] The proximal wall of the slot 334 may comprise a stop projection 335. The stop projection 335 projects into the slot 334. Preferably, the front wall of the stop projection 335 is aligned with the front wall of the 331 platform. Thus, the stop projection 334 does not interfere with the possible movements of the pusher 308. The stop projection 335 prevents the flexible hooks 339 of the button 305 from being placed closer together or, in an alternative embodiment, further away. The stop projection 335 thus helps to prevent disengagement of button 305 and disassembly of cable 302, when cable 302 is allowed to be created or exposed to shock.
[0108] The front portion of the distal part of the cable body 302A is adapted to receive the release button 305. For example, the details of such button are shown in Figure 11. The button 305 is preferably formed as a body with a part projection 340. The projection part 340 protrudes from the far side of the button 305 in relation to the distal front portion of the cable body 302A and away from the cable body 302A. The projection part is adapted to accommodate the substantially spherical part 305A. The substantially spherical part 305A is adapted to contact the user's finger when the button 305 is being actuated. For this purpose, the projection part can be provided with a finger rest portion 340A. The finger rest portion 340A prevents sliding movement between the button 305 and the user's finger as the button 305 is actuated by the user, thus allowing smooth control of the release mechanism. The finger rest portion 340A is preferably produced from suitable elastomeric material, such as rubber, silicone or the like.
[0109] Similarly, the outer surface of the substantially spherical part 305A can also be provided with a finger rest portion. For example, the substantially spherical part 305A can be coated with suitable elastomeric material, such as rubber.
[0110] When cartridge 303 is removed, button 305 is pushed toward cartridge 303 substantially along the longitudinal direction of cable 302. The rear portion of button 305, which can be seen in Figure 14, comprises a pair of lockers 338. Lockers 338 project outwardly from the side of button 305, which engage with cable body 302A. The locks 338 are preferably positioned on one side of the button 305 closest to the cartridge 303, that is, on the most distal part of the button 305. The locks are positioned symmetrically in relation to the longitudinal geometric axis of the shaver 301. Preferably, the locks 338 are deflected in order to allow the 331 platform to be positioned between them. This prevents the latches 338 from being accidentally placed closer together and thus damaged or disengaged from the cable body 302A.
[0111] Platform 331 and latches 338 define an opening through which pusher 308 protrudes. The pusher 308 is configured to reciprocate in that opening. One of the projections 308A provided on pusher 308 engages with rail 331A on platform 331. The rail similar to the rail present on platform 331 can also be provided on the side of button 305 which engages with cable body 302A. As a result, guidance is provided to pusher 308 so that the function of pusher 308 is ensured.
[0112] The pusher 308 cooperates with a spring 309. The cooperation of these two components provides a return means for returning the rotary cartridge 303 to a neutral position when the cartridge 303 is in use and is rotated. Spring 309 can also be provided with a thrust force to push cartridge 303 away from shield bearings 306A after cartridge 303 is disengaged from cable 302.
[0113] Each of the 338 latches is provided in the form of an outwardly oriented hook. When the button 305 is in the rest position, the latches 338 engage the linear part 333 of the non-linear slot 332.
[0114] The internal portion of the button 305, which is in contact with the cable body 302A, comprises a pair of pins 337. The pins 337 are preferably positioned in order to engage the receptacles 330, provided on the arms 306. The receptacles 330 can be in the form of grooves, which can be non-straight and can be tilted, outward and forward.
[0115] The pins provide a means to move the arms 306 closer when the cartridge 303 is to be disengaged. When the button 305 is actuated by the user, it slides along the longitudinal direction of the cable 302 towards the cartridge 303. The pins 337 move forward in the receptacles 330, thus forcing the arms 306 to flex and move to closer. Each shield bearing 306A thus disengages from the corresponding to 303A of cartridge 303. At the same time, cartridge 303 can be pushed out of shield bearing 306A by pusher 308. Therefore, cartridge 303 is removed from the cable 302 and can be replaced with a new one.
[0116] The inner portion of the button 305 additionally comprises flexible hooks 339. The flexible hooks 339 are preferably provided close to the proximal end of the button 305, that is, at the furthest end of the cartridge 303. The flexible hooks 339 protrude from that side of the button 305 that engages the cable body 302A. When the locking and releasing mechanism is assembled, it extends through the slot 334 provided next to the platform 331. The flexible hooks 339 have a general shape of a hook, in which the folded portion is positioned in the distant portion of the flexible hooks 339 Preferably, the hooks that form the inside of the flexible hooks 339 are oriented outwardly, that is, folded outwardly. In this way, the flexible hooks are preferably opposed. In a preferred embodiment, the flexible hooks engage the side walls of the slot 334. The hooks are then retained by the end of the side walls of the slot 334. Preferably, the flexible hooks 339 are snapped onto the rails. These functions prevent the 305 button from disengaging easily. DESCRIPTION OF THE FOURTH ACHIEVEMENT
[0117] The shaver 401 of the fourth embodiment of the invention comprises a handle 402, a cartridge 403 and an actuation button 405.
[0118] The cable 402 comprises a cable body 402A, which can serve as a handle area. The cable body 402A can additionally be produced from low cost material, such as plastic material. Alternatively, the cable body 402A can be produced from any other suitable material, such as metal. The cable body 402A preferably comprises the minimum of components. Preferably, the 402A cable body is produced as one piece. The cable body 402A and / or the button body 405B and / or the substantially spherical part 405A can comprise at least one finger rest area. Finger rest areas can be produced, for example, from rubber or the like. The cable body 402A can be elongated, which comprises an elongated handle portion.
[0119] The actuation button 405 additionally comprises a button body 405B and a substantially spherical part 405A. The substantially spherical part 405A can be located substantially in the middle of the button body 405B. The button body 405B and the substantially spherical part 405A can be produced as two separate parts. Button body 405B can be mounted on cable body 402A so that button body 405B slides substantially along the longitudinal direction of cable 402. Button body 405B is preferably slidably mounted on cable body 402 along the geometric axis X between a first position and a second position. In the first position, the button body 405B is at the furthest point from the 403 cartridge. In the second position, the button body 405B is at a point closest to the 403 cartridge.
[0120] The substantially spherical part 405A can be movable within the button body 405B. For example, the substantially spherical part 405A is mounted on the cable body 402, so that it can move in a direction substantially perpendicular to the XY plane. The substantially spherical part 405A can be movable between an elevated position, when the substantially spherical part 405A protrudes partially out of the button body 405B and a compressed position when the substantially spherical part 405A is completely clamped within the button body 405B.
[0121] The material of the substantially spherical part 405A may have a density different from the material density of the cable body 402A. In this way, the balance of the cable 402 can be improved. Preferably, the difference between the density of the substantially spherical part 405A and the density of the cable body 402A is at least 10% of the density of the cable body 402A.
[0122] The substantially spherical part 405A of the button 405 can be produced in such a way that it adds weight to the distal part of the cable 402. Therefore, the substantially spherical part 405A can be produced from material with a density greater than the density of the material used to produce the 402 handle body. Such additional weight of the substantially spherical part 405A helps to improve the feel of the user during shaving and to improve shaving performance. The additional weight in the distal portion of the handle 402 makes the shaving process more natural and convenient, especially when the handle body 402A is molded from low cost lightweight material, such as plastic material. The additional weight placed on the 405B button body is close to the blades. Therefore, the perception of the blades on the user's skin during the shaving course can be improved. The substantially spherical part 405A can be produced from metal. Alternatively, the substantially spherical part 405A can be produced from metal alloy.
[0123] The substantially spherical part 405A may prevent the button body 405B from sliding along the longitudinal direction of the cable 402 when the substantially spherical part 405A is in the elevated position. In this way, the substantially spherical part can lock the button body 405B in the first position. The substantially spherical part cooperates with the button body 405B to allow the button body 405B to slide towards the second position when the substantially spherical part 405A is in the compressed position.
[0124] The advantage of the 405B button body being locked in the first position, while the substantially spherical part 405A is in the elevated position, is the possibility of using the 405B button body as a finger rest area even more comfortably during the shaving. The user is advantageously allowed to place his finger in close proximity to the blades, so that he can guide the razor blades more effectively. According to the present invention, the only way to disengage the cartridge 403 from the cable 402 is to unlock the button body 405B by pressing the substantially spherical part 405A in a direction substantially perpendicular to the XY plane. The advantage of such an embodiment is that the user can apply almost any desirable force when resting his finger on the actuation button 405 in a direction of the geometric axis X, when the shaver 401 is pushed towards his skin. Therefore, by locking the 405B button body in a first position, the user's safety is further increased. The actuation button 405 can provide support for the user's finger, which is close to the blades, so that the movement of the blades on a user's skin can be carried out more conveniently during shaving.
[0125] The substantially spherical part 405A can thus serve multiple functions. It can operate as a locking mechanism in relation to the sliding of the 405B button body. It can also provide additional weight to the distal part of the cable 402.
[0126] The substantially spherical part 405A may be a sphere. The spherical shape provides directional independence and allows arbitrary placement in the 402A cable body during the production process. The production process of the substantially spherical part 405A can thus be simpler, faster and with less production costs than the production process of other more complex parts. The spherical shape is also comfortable for a user when using the substantially spherical part 405A as a finger rest area.
[0127] The button body 405B and / or the substantially spherical part 405A in the elevated position can serve as a support area for resting the user's finger, for example during shaving. Therefore, the button body 405B and / or the substantially spherical part 405A can be coated with rubber or other elastomeric material to prevent a user's finger from sliding when the finger is resting against the button body 405B and / or the part substantially spherical 405A.
[0128] Alternatively, the button body 405B and / or the substantially spherical part 405A can be produced from a material that inherently restricts sliding movement when in contact with the user's skin. Examples of such a material that prevent sliding movement are elastomeric materials, such as rubber or the like.
[0129] The button body 405B may be provided with an extended portion 444. The extended portion 444 may widen the area, which may serve to rest the user's finger. With the extended portion 444, placing the user's finger on the surface of the button body 405B may become more comfortable for the user. Preferably, the extended portion 444 is covered with a suitable elastomeric material, such as rubber or the like.
[0130] The distal part of the handle 402, according to the fourth embodiment of the present invention, is illustrated in Figures 16 to 19. The locking and releasing mechanism is adapted to be engaged and disengaged releasably from a 403 blade cartridge The cable 402 is provided with an arm assembly comprising a pair of arms 406. Preferably, the arms 406 are positioned symmetrically with respect to the geometric axis X in the cable body 402A. The 403 cartridge can be pivotally mounted on the pair of arms 406. The arms 406 can be flexible. The arms 406 can be produced from any suitable elastic material, such as plastic. Preferably, the arms 406 are integrally molded with the cable body 402A.
[0131] The arms 406 are movable between the resting position, when cartridge 403 is engaged with handle 402, and the release position, when cartridge 403 is disengaged from handle 402. By moving the resting position towards the release position during release of cartridge 403, arms 406 can move closer to each other. An alternative embodiment, when the arms 406 are further apart during the disengagement of the cartridge 403, is also possible.
[0132] When the arms 406 are moved closer to the release position, the arms 406 can generate an elastic return force, which forces the arms 406 back to the resting position. The arms 406 can therefore be elastically tilted towards the resting position when the button 405 is actuated. After the button 405 is released by the user, it can be pushed back to the first position by the tilt force generated by the pair of arms 406. The arms 406 and the corresponding button functions 405 can be constructed, for example, as described in Document WO2010 / 037418A1.
[0133] As shown in Figure 19, the arms 406 can be provided with shield bearings 406A by means of which the cartridge 403 is mounted on the cable 402. For example, in the resting position, the shield bearings 406A are engaged in the rims corresponding (not shown) provided in cartridge 403. The rims and shield bearings 406A allow the cartridge 403 to rotate around the Y-rotating geometry axis. Any alternative means for securing the 403 rotary blade cartridge can be used, such as like corresponding or similar pins and holes.
[0134] Alternatively, the arms 406 can be compatible with an intermediate structure attached to the cartridge 403. The arms 406 can then engage and disengage with the intermediate structure, or both the cartridge 403 and an intermediate structure.
[0135] In a preferred embodiment, the pair of arms 406 is adapted to cooperate with the actuation button 405. Upon the actuation of the actuation button 405, the two arms 406 are moved closer by means of the cam action between the actuation button 405 and the pair of arms 406. As the button body 405B is slid forward along the geometric axis X from the first position to the second position towards the 403 shaver cartridge, the pair of arms 406 move closer from the rest position towards the release position.
[0136] Each arm 406 comprises a receptacle 430. The receptacles 430 are provided on the front surface of each respective arm 406. The receptacles 430 may have a non-linear shape. For example, receptacles 430 may have a shape substantially similar to the beam. The receptacles 430 are preferably moving away from each other from the proximal part to the distal part of the cable 402 in relation to the longitudinal direction given by the geometric axis X. The receptacles 430 can be in the form of grooves, which can be not straight and can be tilted outwards and forwards. The receptacles 430 are adapted to receive pins 437 provided in the button body 405B. The receptacles are preferably configured so that when the button body 405B moves forward to the second position, the arms 406 tend to move closer to each other, while when the button 405 returns to its first position, the pair with arms 406 swerves back away.
[0137] The lower portion of the button body 405B comprises a pair of pins 437. When the cartridge 403 is released from the handle 402, the arms 406 are flexed to be placed closer together. Pins 437 provide a means to move arms 406 closer when cartridge 403 is to be disengaged. The pins 437 are preferably positioned to engage the receptacles 430, provided in the arms 406. The cartridge 403 can therefore be disengaged from the shield bearings 406A and removed or replaced. Pins 437 engage receptacles 430 to drive arms 406. Pins 437 engage receptacles 430 to flex arms 406 when button body 405B is pushed from the first to the second position. When button 405 is actuated by the user, button body 405B slides along the geometric axis X towards cartridge 403. Pins 437 move forward in receptacles 430, thereby forcing arms 406 to flex and move closer. Each shield bearing 406A thus disengages from cartridge 403. Therefore, cartridge 403 is removed from cable 402 and can be replaced with a new one.
[0138] Between the arms 406, an elastic tongue 445 can be positioned. The elastic tongue 445 can return the cartridge 403 to a neutral position, when the cartridge 403 rotates about the geometric axis Y. Preferably, the elastic tongue 445 is located on the geometric axis X or parallel to it. Alternatively, the elastic tongue 445 can be replaced by any other return force that generates means, such as a plunger or the like.
[0139] The button body 405B can have a cavity 414, which is opened towards the cable body 402A. The substantially spherical part 405A is located substantially within the cavity 414. The cavity 414 can be dimensioned so that the substantially spherical part 405A can fully enter the cavity 414, as the substantially spherical part 405A is in the compressed position. The button body 405B may additionally include a cover 404 that partially covers the cavity 414 opposite the cable body 402A. In the elevated position, the substantially spherical part 405A can project partially upward out of the button body 405B through a through hole 427. The through hole 427 is arranged in the cover 404 of the button body 405B. The through hole 427 is adapted to prevent the substantially spherical part 405A from escaping from the cavity 414 of the button body 405B. When located in the through hole 427, the substantially spherical part 405A is preferably restricted to movement from side to side. For example, through hole 427 may have a substantially circular cross-section with a diameter smaller than the diameter of the substantially spherical part 405A.
[0140] The cable body 402A comprises a guide 443 that extends rigidly in the cavity 414 of the button body 405B towards the cover 404. The guide 443 can be in the form of a wall or an integral post with the cable body 402A. The substantially spherical part 405A can rest against the guide 443 towards the arm assembly. Preferably, the substantially spherical part 405A rests against the guide all the way from the raised position to the compressed position, so that the substantially spherical part 405A is guided towards the interior of the button body 405B. In this way, the substantially spherical portion is oriented with respect to the cable body 402A substantially perpendicular to the longitudinal direction of the cable between the elevated position and the compressed position.
[0141] The cable body 402 may further comprise a recessed portion 450 hollow substantially under the cavity 414 of the button body 405B. The recessed portion 450 may preferably be designed to allow at least partial entry of the substantially spherical component 405A, as the substantially spherical portion 405A is clamped in the compressed position. For example, the recessed portion 450 may be concave, so that the substantially spherical portion engages with the recessed portion 450. In addition, there may be a spring 442 disposed within the recessed portion 450. The spring is preferably positioned between the substantially spherical portion 405A and the cable body 402A. The spring 442 facilitates the application of tilt force, which pushes the substantially spherical part 405A back from the compressed position to the elevated position. If no pressure is applied to the substantially spherical part 405A by a user, the force provided by the return spring 442 can keep the substantially spherical part 405A in the elevated position. Alternatively, spring 442 can be replaced with a leaf spring or other means that provides the return force.
[0142] Figure 16 shows the distal part of the cable 402 with the substantially spherical part 405A in the elevated position. With the substantially spherical part 405A in the elevated position, the button body 405B is in the first position and the arms 406 are in the resting position. In the elevated position, the substantially spherical part 405A rests against the guide 443 towards the arm assembly. In addition, in the elevated position, the substantially spherical part is fixed within the through hole 427 of the cover 404 in relation to the longitudinal direction of the cable. Therefore, in the elevated position, the substantially spherical part 405A prevents the button body 405A from sliding. The button body 405B is then locked by the substantially spherical part 405A in the first position. By pressing the substantially spherical part 405A, the user can invite the movement of the substantially spherical part 405A towards the compressed position.
[0143] Figure 17 shows the distal part of the cable 402 with the substantially spherical part 405A in a middle position, which corresponds to the substantially spherical part 405A to be substantially halfway between the raised position and the compressed position. With the substantially spherical part 405A in the middle position, the inclined surface 417 of the button body 405B is allowed to slide along the substantially spherical part 405A. Consequently, the button body 405B is released to slide into the second position. The user can then push the button body 405B forward along the X geometric axis towards the second position. From the cam action, the button body 405B begins to cooperate with the arms 406, so that the arms 406 begin to flex more closely towards the release position. As the button body 405B is slid forward to the second position and the substantially spherical part 405A slides along the inclined surface 417, the substantially spherical part is pressed by the inclined surface 417 of the button body 405B to the compressed position. Since the substantially spherical part 405A rests against the guide 443, the substantially spherical part 405A cannot move forward in a direction towards the arm assembly as the substantially spherical part 405A slides along the inclined surface 417.
[0144] Figure 18 shows the distal part of the cable 402 with the substantially spherical part 405A in the compressed position. With the substantially spherical part 405A in the compressed position, the button body 405B is in the second position and the arms 406 are in the release position, so that the cartridge 403 can be removed / replaced. In the compressed position, the substantially spherical part 405A is squeezed into the cavity 414 of the button body 405B. In addition, the substantially spherical part 405A still rests against the guide 443. For these reasons, the button body 405B cannot slide further towards the arm assembly. Preferably, in the compressed position, the substantially spherical part enters the recessed portion 450. With the substantially spherical part 405A in the compressed position, the spring 442 is completely clamped within the depressed portion between the substantially spherical part 405A and the cable body 402A.
[0145] Once the user stops pushing the button body 405B forward, the button body 405B can be forced all the way back to the first position by means of the return force generated by the elastic arms 406. Additionally, by means of of the cam action between spring 442, the substantially spherical part 405A and the button body 405B, the return force generated by the spring 442 can contribute to pushing the button body 405B back to the first position. As the substantially spherical part 405A returns to the elevated position, the substantially spherical part 405A is oriented along the guide and slides back along the inclined surface 417. Therefore, the substantially spherical part 405A forces the button body 405B back to the first position.
[0146] Figure 21 shows examples of the actuation button 105 from the first realization, in all examples the actuation button 105 comprises two different materials. Even so, the number of materials included in the actuation button 105 can be greater. In the following paragraphs, although references are made to the actuation button 105 of the first embodiment only, the same or similar structures of the actuation button or the substantially spherical part can also be employed in the other embodiments of the invention. The actuating button material 105 may have an average density greater or less than the material density of the cable body 102A. Preferably, the difference between the average density of the actuation button 105 and the density of the cable body material 102A is at least 10% of the density of the cable body material 102A.
[0147] Advantageously, actuation button 105 can comprise a plurality of different materials with different densities. Some of these materials may have densities greater than the material of the cable body 102A and some of these materials may have densities less than the material of the cable body 102A. The use of a combination of multiple materials of actuation button 105 can have an advantage both of increasing the weight of the cable 102 and providing a grip and / or rest area for the user's finger. Weight gain materials with a density greater than the material of the 102A cable body may have a high density, of plastic, metal, or other materials. Low drop materials with a lower density than the 102A cable body material can be a plastic, rubber or other suitable lightweight material.
[0148] The combination of materials can be selected so that an average density of the plurality of materials is different from the material density of the cable body 102A. The difference between the average density and the material density of the cable body 102A can preferably be at least 10% of the density of the cable body 102A.
[0149] Figure 21a shows a spherical actuation button 105 that comprises a material B of greater density than the material of the cable body 102A inside the actuation button 105 and a material A of lesser density than the material used for the cable body 102A is produced on the outside of the actuation button 105. Even so, the reverse arrangement of materials is also possible.
[0150] Figure 21b illustrates a material D inside the actuation button 105 and partly protruding from the outside of the actuation button 105. Alternatively, as shown in Figure 21c, the actuation button 105 can include a single material E and a hollow portion F inside. The hollow portion F has, therefore, a density equal to zero or very close to zero. Figure 21d shows another example in which a material G supplied in the center of the spherical actuation button 105 projects in several directions towards the outside of the actuation button 105 through an H material.
