field of invention
[001] The present disclosure relates to a comb that can be attached to an apparatus for hair cutting. The present disclosure further relates to a hair-cutting apparatus to which an attachable comb can be attached. More particularly, the present disclosure relates to a hair trimming apparatus which is operable in a hair trimming mode and in a shaving and waxing mode. Background of the invention
[002] WO 2013/150412 A1 discloses a hair cutting apparatus and a corresponding blade set of a hair cutting apparatus. The blade assembly comprises a stationary blade and a mobile blade, the mobile blade being reciprocally driven with respect to the stationary blade to cut hair. The set of blades is particularly suitable for enabling both trimming and shaving or waxing operations.
[003] For the purpose of cutting body hair, there are basically two types of electrically powered appliances usually distinguishable: the electric shaving or shaving apparatus, and the hair trimmer or clipper. In general, the electric razor or epilator is used for shaving or waxing, that is, to cut body hair at skin level in order to obtain smooth skin without hair stumps. The hair trimmer is normally used to cut the hair at a chosen distance from the skin, that is, to cut the hair to a desired length. The application difference is reflected in the different structure and architectures of the cutting blade layout implemented in any apparatus.
[004] An electric shaving or waxing apparatus typically includes a metal foil, i.e. an ultra-thin perforated screen, and a cutting blade that is movable along the interior of and relative to the foil. During use, the outside of the foil is placed and pushed against the skin so that any hairs that penetrate the foil are cut by the cutting blade that moves relative to the interior of the foil, and fall into the hollow collection portions of hair inside the razor or epilator.
[005] An electric hair trimmer, on the other hand, typically includes two cutter blades having a serrated edge, one placed on top of the other so that their respective serrated edges overlap. In operation, the cutter blades reciprocate with respect to each other, cutting any hairs that are trapped between their teeth in a scissors action. The exact level above the skin at which hair is cut is usually determined by means of an additional attachable part called a pad or comb (spacer).
[006] Additionally, combined devices are known which are basically adapted for both shaving or waxing and trimming purposes. However, these devices merely include two separate and distinct cutting sections, namely, a shaving or epilating section comprising a configuration that corresponds to the concept of electric razors or epilators as set out above, and a trimming section comprising a configuration which, on the other hand, corresponds to the concept of fur trimmers.
[007] Ordinary electric shaving or epilating devices are not particularly suitable for cutting hair to a desired variable length above the skin, ie for precise trimming operations. This can be explained, at least in part, by the fact that they do not include mechanisms to space the foil, and hence the cutting blade, from the skin. However, even if they included, for example by the addition of spacer fastening parts such as spacing combs, the sheet metal configuration, which normally involves a large number of small perforations, would decrease the efficient capture of all at least the shortest ones. and harder.
[008] Similarly, common hair trimmers are not particularly suitable for shaving or waxing, mainly because the separate cutter blades require a certain rigidity and therefore thickness, to perform the scissors action without deformation. It is the minimum required skin-facing blade thickness that prevents hair from being cut close to the skin. Consequently, a user who wants to either shave or shave or trim their body hair may need to purchase and use two separate appliances.
[009] Additionally, combined shaving or waxing and trimming devices show several disadvantages, as they basically require two sets of cutting blades and respective drive mechanisms. As a result, these devices are heavier and more susceptible to wear and tear than standard, single-function hair clippers, and they also require expensive assembly and manufacturing processes. Similarly, the operation of these combined devices is often considered quite uncomfortable and complex. Even in case a conventional combined shaving or waxing and trimming device is used, which comprises two separate cutting sections, handling the device and switching between different operating modes can be considered to be time consuming and not very user-friendly. Since the cutting sections are normally installed in different places on the device, the orientation accuracy (and therefore also the cutting accuracy) can be reduced, as the user needs to get used to two dominant and distinct ways of holding the device. device during operation.
[010] Document No. WO 2013/150412 A1 above solves some of these problems by providing a set of blades comprising a stationary blade that houses the movable blade so that a first portion of the stationary blade is disposed on the side of the blade mobile facing the skin, when used for shaving or waxing, and that a second portion of the stationary blade is disposed on the side of the mobile blade in the opposite direction to that of the skin in use. Additionally, in a serrated cutting edge, the first portion and the second portion of the stationary blade are connected, thus forming a plurality of stationary teeth that cover the respective teeth of the movable blade. Consequently, the movable blade is countered by the stationary blade.
[011] This arrangement is advantageous in that the stationary blade can provide the set of blades with better strength and rigidity, since the stationary blade is also present on the side of the mobile blade facing the opposite side of the skin. This can generally enable a reduction in the thickness of the first portion of the stationary blade on the skin-facing side of the movable blade. Consequently, since in this way the movable blade can be closer to the skin during the operation, the set of blades above is well suited for shaving or hair removal operations. Furthermore, the set of blades is also particularly suitable for hair trimming operations, since the configuration of the cutting edge, including the respective teeth that alternate with slots, also allows longer hairs to enter the slots and, consequently, are cut by the relative cutting movement between the moving blade and the stationary blade.
[012] However, there is still a need for improvement in hair-cutting devices. This can particularly involve aspects related to user comfort and aspects related to performance. Particularly with pile cutting apparatus comprising blade assemblies that are pivotally secured to the housing, operating the apparatus in different modes of operation can present a number of challenges. In particular, it may be difficult to reliably space the blade assembly of such a device from the user's face. For example, EP 2 1457 40 A1 discloses a haircutting apparatus in accordance with the preamble of claim 1 and US 4,614,036 discloses a removable holding comb in accordance with the preamble of claim 15. Invention Summary
[013] It is an object of the present disclosure to provide an attachable comb arranged for trimming operations that can be easily attached to and detached from a hair-cutting apparatus. More preferably, the present disclosure can solve at least some disadvantages inherent in haircutting blades known from the prior art, as discussed above, for example. It is additionally preferred to provide a hair-cutting apparatus arranged to be selectively operated in a shaving or waxing mode and in a trimming mode. It is particularly preferred that the attachable comb improves the trimming performance of the hair trimmer.
[014] In a first aspect of the present disclosure, a hair cutting apparatus arranged to be moved through the hair in a direction of movement to cut the hair is presented, said hair cutting apparatus comprising a set of blades , particularly a pivotally mounted blade assembly, and an attachable comb, said attachable comb comprising: - a support structure, - at least one bulkhead spacer element arranged to space the blade assembly from a work surface when in operation, particularly spacing one side of it, which faces the skin, of a user's skin. - a mounting portion arranged to be secured to a housing portion of the hair-cutting apparatus, and - an orientation determining portion arranged to engage the blade assembly and to define a locking orientation of the blade assembly when mounted to the apparatus for hair cutting.
[015] This aspect is based on the understanding that the attachable comb can serve several purposes. On the one hand, the attachable comb can space the set of blades from the skin, so as to define the length of the (remaining) hair. On the other hand, the attachable comb can activate the trimming mode on the apparatus by bringing the blade assembly into the desired orientation, for example a trimming orientation. It is preferred that the blade assembly is locked in trimming mode, i.e. the blade assembly cannot be rotated relative to the apparatus housing. Needless to say, the blade assembly as such is still operable in the locking orientation, i.e. a movable blade assembly cutting blade can be moved relative to the stationary blade assembly blade. It is additionally preferred that the attachable comb can trigger or induce the locking orientation when being mounted on the hair trimming apparatus.
[016] In shaving or waxing mode, when the attachable comb is separated from the hair trimmer, the blade assembly can be pivoted relative to the housing, thus providing an ability to follow contours. As a result of removing the attachable magazine, the blade assembly can be released from its relatively fixed orientation in the locking configuration. Consequently, the blade assembly can be pivoted or pivoted relative to the housing portion in shaving or waxing mode.
[017] It is worth mentioning in the context that the attachable comb can preferably be mounted to hair-cutting apparatus that comprise sets of blades that are arranged as sets of dual-use or multi-purpose blades. Consequently, the same set of blades can be used for trimming and for shaving or waxing.
[018] In one embodiment, the orientation determining portion is arranged to block a rotating mechanism that couples the set of blades and the housing portion of the hair-cutting apparatus. Locking the swivel mechanism may result in the blade set being locked. Alternatively, or in addition, locking the swivel mechanism may involve locking an element of the swivel mechanism to which the set of blades is attached, for example a bar of a 4-bar coupling mechanism.
[019] According to the invention, the mounting portion further comprises at least one retaining element, particularly at least one resilient snap-fit hook, the at least one retaining element being arranged to engage a mounting contour. in the housing portion, and the at least one retaining member being arranged to bias the mounting contour when mounted to the hair-cutting apparatus. Preferably, the at least one retaining element can be actuated without the need to directly operate the retaining element, i.e. without the need to directly push or pull the retaining element. Consequently, the at least one retaining element can be arranged as a mediatedly actuable or, instead, self-actuating retaining element.
[020] In one embodiment, the at least one retaining element is a pre-strained mounting element, particularly a resilient flexible mounting element or a spring-strained mounting element. Consequently, a locking force can be generated. As a result, the attachable comb can be forced or moved into the desired position relative to the hair trimmer and its blade assembly.
[021] In one embodiment, the at least one retaining element is rotatably secured or integrally formed in the support structure, the support structure contacting the at least one retaining element and the determining portion of guidance. Therefore, the at least one retaining element can apply a locking force to the structure and, consequently, to the orientation determining portion that can contact the blade assembly.
[022] According to the invention, the at least one retaining member is arranged to apply an alignment force to the housing portion when mounted on the hair-cutting apparatus, the alignment force pressing the orientation determining portion to engagement with the blade set, and the blade set is pressed into the lock orientation.
[023] In one embodiment, the at least one retaining element comprises a sliding surface arranged to cooperate with a sliding inclined surface associated with the mounting contour, wherein the sliding surface and the sliding inclined surface deflect the at least one retaining element after mounting the attachable comb so that a retaining surface of the retaining element engages an engaging surface associated with the mounting contour. This can have the advantage that the retaining element can automatically engage the mounting contour in the course of mounting the attachable comb.
[024] In one embodiment, the attachable comb further comprises a handling tab, particularly a user actuable release handling tab, wherein the at least one retaining element is disengaged from the assembly contour after applying a force release to the handle flap.
[025] The disengagement of the retaining element may involve the deflection or curvature of the retaining element, so that the retaining surface can be released from the engagement surface. Preferably, disengagement may involve rotation of the retaining member so that the retaining surface can span an apex point between the engaging surface and the sloped sliding surface of the mounting contour.
[026] In one embodiment, the handling tab is coupled to the at least one retaining element, the handling tab being selectively actuable to disengage the at least one retaining element from the housing portion. According to this modality, the user can directly actuate the retaining element to disengage or engage the retaining element.
[027] In one embodiment, the orientation determining portion rotates the set of blades against a rotation limiting locking element associated with the housing portion. As a result, the blade assembly can be held with relatively high accuracy in the desired locking orientation.
[028] In an alternative embodiment, the orientation determining portion rotates the set of blades against a tensioning force to guide the set of blades applied by a tension element associated with the housing portion. By way of example, the swivel mechanism can be provided with a tension element. In general, the tension element can push the swivel mechanism and hence the blade assembly to a neutral position. As a result of the attachment of the attachable comb, the orientation determining portion can tension the blade assembly against the tension force applied by the tension element to the desired locking orientation.
[029] In one embodiment, the attachable comb is arranged as a hair trimming comb, with the orientation determining portion being arranged to induce a trimming orientation of the blade assembly when the attachable comb is mounted on the apparatus for cutting hair. hairs, the trimming orientation particularly involving a defined angular orientation of the blade assembly with respect to the housing portion. The attachable comb may comprise a plurality of comb teeth which can space the array of blades from the skin when in operation.
[030] In one embodiment, the attachable comb additionally comprises an insertion portion adjacent to the orientation determining portion, the insertion portion being configured to facilitate imposing or placing the attachable comb on the blade assembly in a mounting direction. Consequently, assembly failures can be avoided. The assembly process can be further simplified.
[031] In one embodiment, the mounting direction is adapted to a standard orientation of the blade assembly with respect to the housing portion. As indicated above, the blade assembly can assume a standard or neutral orientation when no external load is applied to it. Therefore, it is particularly beneficial to adapt the insert portion to the standard blade set orientation.
[032] Mounting the attachable comb may involve bringing the blade assembly closer in the mounting direction and, after placing the blade assembly in contact with the orientation determining portion, rotating the attachable comb around the laterally extending axis, which can be basically parallel to the pivot axis or virtual pivot axis of the set of blades.
[033] In one embodiment, the mounting portion further comprises at least one side clip element, particularly a first side clip element, and a second side clip element opposite the first side clip element, wherein the at least one side clamp element is configured to engage the housing portion after the attachable comb has been rotated in the mounting orientation, thus pushing the blade assembly into the locking orientation.
[034] In a related embodiment, the mounting portion comprises a first side cleat element and a second side cleat element, wherein the first side cleat element and the second side cleat element are arranged to embrace the housing portion when the attachable comb is mounted on the hair-cutting apparatus, the first side clip element and the second side clip element exerting opposing retaining forces, the opposing preferential retaining forces being preferably perpendicular to a alignment force applied by the retaining element. However, several modalities can be contemplated that can be implemented without the side loop elements.
[035] In one modality of the hair-cutting apparatus, the apparatus is operable to shave or shave in a shaving or waxing mode, the set of blades being configured to rotate in the shaving or waxing mode, with an orientation The actual blade set is adaptable to a work surface, particularly a user's skin, and the appliance, when equipped with the attachable comb, is operable to trim hair in a trimming mode, whereas the blade set is pushed into the lock orientation by means of the attachable comb in the trim mode.

[055] Figure 1 schematically illustrates, in a simplified perspective view, an exemplary embodiment of an apparatus for cutting hair 10, particularly an apparatus for cutting electrical hair 10. The apparatus for cutting 10 may comprise a housing or more particularly a housing portion 12, an engine indicated by a dashed block 14 in the housing 12 and a drive mechanism or a transmission system indicated by a dashed block 16 in a housing 12. To drive the engine 14, at least some embodiments of the cutting apparatus 10, an electric battery, indicated by a dashed block 17 in the housing portion 12, may be provided, for example a rechargeable battery, a replaceable battery etc. However, in some embodiments, the cutting apparatus 10 may also be provided with a power cord for connection to a power source. A power supply connector can be provided in addition to or as an alternative to the electric (internal) battery 17.
[056] The cutting apparatus 10 may further comprise a cutting head 18. In the cutting head 18, a set of blades 20 can be attached to the apparatus for cutting hair 10. The set of blades 20 can be driven by the motor 14 through the drive mechanism or drive train 16 to enable a cutting movement. Cutting motion can generally be thought of as relative motion between a stationary blade and a moving blade which are hereinafter described and discussed in more detail. In general, a user can hold, hold and manually guide the cutting apparatus 10 through the hairs in a direction of movement 28 to cut the hairs. The cutting apparatus 10 can generally be considered as an electrically powered device for manual operation and guidance. Furthermore, the cutting head 18 or, more particularly, the blade assembly 20 can be connected to the housing portion 12 of the cutting apparatus 10 in a pivotal manner, as shown by the double curved arrow indicated by the reference numeral 26 in the Figure. 1. In some embodiments, the shaving apparatus 10 or, more specifically, the shaving head 18 including the blade assembly 20 can be moved along the skin to cut hair that grows on the skin. By cutting the hairs close to the skin, basically a shaving or waxing operation can be performed, aiming to cut or shave the hairs at skin level. However, cutting (or trimming) operations can also be contemplated, whereby the cutting head 18 comprising the blade assembly 20 is passed along a path at a desired distance from the skin.
[057] When guided or moved through the hairs, the cutting apparatus 10 including the blade assembly 20 is typically moved along a common movement direction which is indicated by reference numeral 28 in Figure 1. It is worth mentioning in this connection whereas, considering that the hair-cutting apparatus 10 is normally guided and moved manually, the direction of movement 28 does not therefore necessarily have to be interpreted as a precise geometric reference that has a fixed definition and relationship with respect to the orientation of the apparatus. for cutting hair 10 and its cutting head 18 to which the blade assembly 20 is attached. That is, a general orientation of the hair-cutting apparatus 10 in relation to the hairs to be cut on the skin can be interpreted as somewhat fickle. However, for purposes of illustration, it can reasonably be assumed that the (imaginary) direction of motion 28 is parallel (or generally parallel) to a central principal plane of a coordinate system which may then serve as a means of describing structural features. of the hair-cutting apparatus 10.
[058] For ease of reference, coordinate systems are indicated on several drawings in this document. By way of example, an X-Y-Z Cartesian coordinate system is shown in Figure 1. An X geometric axis of the respective coordinate system extends in a generally longitudinal direction that is generally associated with length, for the purpose of this disclosure. A geometric Y axis of the respective coordinate system extends in a lateral (or transverse) direction associated with width, for the purpose of this disclosure. A geometric axis Z of the coordinate system extends in a height (or vertical) direction which may also be called, for illustrative purposes, at least in some embodiments, a generally vertical direction. It is evident that an association of the X-Y-Z coordinate system with the characteristic features and/or modalities of the pile cutting apparatus 10 is primarily provided for illustrative purposes and will not be interpreted in a limiting way. It should be understood that those skilled in the art can readily convert and/or transfer the coordinate system provided herein when confronted with alternative embodiments, respective Figures and with illustrations that include different orientations. It further goes without saying that, for the purpose of the present disclosure, the X-Y-Z coordinate system is generally aligned with the main directions and orientations of the cutter head 18 including the blade assembly 20.
[059] Figure 2 shows a top perspective view of a set of blades 20 that can be implemented in the cutter head 18 illustrated in Figure 1. The stationary blade 22 of the set of blades 20 can define at least one toothed leading edge 30a, 30b which comprises a plurality of teeth. Likewise, the movable cutting blade 24 may comprise respective toothed front edges provided with respective teeth. The movable cutting blade 24 is shown in Figure 2 with a dashed line. The movable blade 24 can be driven by a drive shaft 48 reciprocally. Consequently, the movable blade 24 and the stationary blade 22 can be reciprocally moved relative to one another and therefore cooperate to cut hairs that enter gaps between the teeth on the at least one toothed leading edge 30a, 30b when the cutting apparatus of hair 10 is moved through the hair in the direction of movement 28. As already indicated above, the blade assembly 20 may be particularly suitable for shaving or waxing and trimming operations. Shave or waxing performance can be further improved when the blade set 20 is able to follow a real skin contour. Accordingly, it may be preferred that the blade assembly 20 is pivotally secured to the housing or housing portion 12 of the cutting apparatus 10.
[060] The stationary blade 22 can be arranged as a shield for the movable blade 24. It is particularly preferred that the stationary blade 22 comprises a first wall portion and a second wall portion, which are at least partially spaced from each other, so that a guide slot for the movable blade 24 is defined between them. Consequently, the stationary blade 22 can also cover the movable blade 24 on at least one toothed leading edge 30a, 30b. Blade assembly 20 can be attached to a swivel mechanism 40. swivel mechanism 40 can form a portion of cutter head 18 which is interposed between blade assembly 20 and housing portion 12. swivel mechanism 40 can define a pivot or, instead, a virtual pivot for the blade set 20; see double curved arrow 26 in Figures 1 and 2.
[061] The swivel mechanism 40 may further comprise a limiter lock 42 to define a maximum angle of rotation of the blade assembly 20 relative to the housing portion 12. At least one contact surface 44 may be associated with the blade assembly 20. Consequently, when the blade assembly 20 is rotated about the pivot axis or the virtual pivot axis, the contact surface 44 can contact the limiter lock 42 and thus limit the pivotal movement. The cutter head 18 can be considered as a replaceable cutter head. The cutting head 18 may comprise a clamping interface 46 which is arranged to engage a respective receiving interface with the housing portion 12 of the lint cutting apparatus 10. In particular, the cutting head 18 may be arranged as a cutting head. 18 pluggable. As already indicated above, the blade assembly 20, particularly the movable cutting blade 24 thereof, can be coupled to the drive shaft 48. The drive shaft 48 may comprise an eccentric portion which can rotate about a longitudinal axis of the drive shaft 48. Accordingly, an eccentric cutting mechanism can be provided to reciprocally drive the movable cutting blade 24 with respect to the stationary blade 22.
[062] When the swivel mechanism 40 illustrated in Figure 2 or another exemplary embodiment of a swivel mechanism 40 is installed in the shaving head 18 it may be particularly suitable for shaving or waxing operations. However, it is preferred that the cutter head 18 is also suitable for hair trimming operations. Hair trimming may involve cutting hair to a desired length. The desired remaining length of hair can be defined with a so-called attachable comb. An attachable comb can generally space the blade assembly 20 from the surface of the skin. When attaching the attachable comb to the hair-cutting apparatus 10, it should be considered that the blade assembly 20 is basically pivotally mounted to the housing portion 12. The pivotally mounting can improve the shaving or waxing performance of the hair-cutting apparatus 10. However, on the other hand, it may be preferable to lock or lock the orientation of the blade assembly 20 in the trimming mode. Locking blade assembly 20 may involve holding blade assembly 20 in a desired trimming orientation.
[063] With reference to Figures 3 to 17, exemplary embodiments of the attachable comb 50 will be illustrated and described further below. With specific reference to Figures 3 to 7, a first exemplary embodiment of an attachable comb 50 will be elucidated. As best seen from Figures 3 and 4, the attachable comb 50 may comprise a support structure 52. The support structure 52 may comprise a support rod 54 which may be arranged to engage a housing portion 12 of the apparatus. for cutting hair 10. To that end, an engaging locking element 56 may be secured to the support rod 54. The attachable comb 50 may generally comprise a mounting portion 60 which is arranged to define a predefined orientation of the attachable comb 50 with respect to housing portion 12. Mounting portion 60 may be provided with a catch locking element 56, for example. Engagement locking element 56 may be arranged to engage with a mounting contour 90, particularly a mounting recess in the housing portion 12. As can best be seen from the sectional representation of the cutting head 18 of the cutting apparatus. bristles 10 in Figure 3, the cutting head 18 may comprise a blade assembly 20 which is pivotally connected to the housing portion 12. However, when the attachable comb 50 is attached to the bristle cutting apparatus 10 in a manner of trimming, it is preferred that the blade assembly 20 is placed or held in a preferred trimming orientation which may also be called a locking orientation. The locking orientation of the blade assembly may involve a preferred angular orientation. In other words, the blade assembly 20 can be arranged at an angle α with respect to the attachable comb 50 and, consequently, to the housing portion 12.
[064] The attachable comb 50 may additionally comprise an orientation determining portion 62. The orientation determining portion 62 may be arranged to define the locking orientation or the trimming orientation of the blade assembly 20 when the attachable comb 50 is attached to the housing portion 12 and the blade assembly 20 has been configured in a predefined manner. By way of example, the orientation determining portion 62 may comprise a receiving base 64 which may be arranged to contact the top surface 32 (see Figure 5) of the blade assembly 20, at least sectionally. Assuming its predetermined orientation, the attachable comb 50 can basically bias the blade assembly 20 into a locking orientation.
[065] As can best be seen from the perspective view of Figure 4, the attachable comb 50 may further comprise a bulkhead spacer element 58 which may enclose a plurality of comb teeth 66. The comb teeth 66 may be arranged to come in contact with the user's skin when the hair trimmer 10 is used for hair trimming operations. The bulkhead spacer element 58, particularly the comb teeth 66 thereof, can distance the toothed leading edge 30 of the blade assembly 20 from the skin and thus define an actual (remaining) length of hairs. As can best be seen from Figure 4, the blade assembly 20 can be attached to a swivel mechanism 40 which can be arranged as a 4-bar coupling mechanism. The swivel 40 may comprise a tension element 69, particularly a spring element 69, with reference to Figure 4. The tension element 69 may be arranged to bias the blade assembly to a predetermined neutral position. The neutral position can be thought of as the position of the blade assembly 20 that is adopted when no external load is applied to the blade assembly 20. Consequently, the orientation determining portion 62 can act against the spring element 69 to bias the blade assembly blades 20 to the desired locking orientation for trimming purposes.
[066] As can best be seen from Figure 4, the attachable comb 50 can basically comprise a shovel-like shape. The support structure 52 and the bulkhead spacer member 58 may form a bulkhead for the top surface 32 of the blade assembly 20. As best seen from Figure 5, the mounting portion 60 may be arranged to be placed in the blade assembly 20 in a mounting direction 74. The attachable comb 50 may further comprise a defined insert portion 70 which may basically comprise a slot which is adapted for the lateral extension (Y dimension) of the blade assembly, with reference also to to Figure 2. When the orientation determining portion 62 is placed on the blade assembly 20, the blade assembly 20 can enter the insertion portion 70. The blade assembly 20 can be placed in contact with the receiving base 64. At a front part thereof, particularly on a serrated front edge 30 thereof, the blade assembly 20 can be brought into contact with a front contact surface 67.
[067] Figures 5, 6 and 7 illustrate an exemplary assembly of the attachable comb 50. Referring to Figure 5, in an initial state, the attachable comb 50 can approach the set of blades 20 in the assembly direction 74, so that the blade assembly 20 may contact the orientation determining portion 62. This may particularly involve bringing the front contact surface 67 into contact with the front end of the blade assembly 20. The respective mounting movement may be called a substantially straight motion. At a later stage, illustrated in Figure 6, the attachable comb 50, which may already be in contact with the blade assembly 20, can be rotated together with the blade assembly 20 in a rotatable mounting direction 76. Consequently, the portion mounting bracket 60 may approach housing portion 12 of hair trimming apparatus 10.
[068] Assembling the mounting portion 60 to the housing portion 12 may include snap-fitting the mounting portion 60. For this purpose, at least in some embodiments, the mounting portion 60 may comprise at least one side tab 72 , particularly a pair of side loops which are arranged opposite each other. The side tabs 72 can engage opposite side sides of the housing portion 12. The side tabs 72 can push the engaging locking element 56 into contact with the mounting contour 90 on the housing portion 12. Accordingly, the attachable comb 50 can be releasably affixed to housing portion 12 in a pre-set snap fit fashion. Attaching the attachable comb 50 in a predetermined orientation may include placing the blade assembly 20 in its locking orientation.
[069] With further reference to Figures 8 to 15, a further exemplary embodiment of an attachable comb 50 for a hair-cutting apparatus 10 will be detailed and described in more detail. As can best be seen from Figures 8, 12 and 13, the attachable comb 50 may be secured to a housing or housing portion 12 of the hair trimming apparatus 10, which may also include engaging a blade assembly. 20 of lint cutting apparatus 10. It should further be noted that a swivel mechanism for blade assembly 20 is concealed in Figures 8 through 15 for illustrative purposes. In general, the blade assembly 20 and the swivel mechanism may be arranged in accordance with the exemplary embodiment of the swivel mechanism 40 illustrated in Figure 2. As best seen from Figures 8 and 9, the attachable comb 50 may comprise a support structure 52, particularly a support structure 52 shaped like a loop. As best seen from Figures 8 and 10, the attachable comb 50 may further comprise a spacer spacer element 58 which may comprise a plurality of comb teeth 66. The spacer spacer element 58 may space or distance the surface of top 32 of the blade assembly 20 of the user's skin in a predefined shape to enable the trimming of hairs to a predefined length. For purposes of illustration, the bulkhead spacer element 58 is hidden in Figures 9 and 11 through 15. In some embodiments, the bulkhead spacer element may be called an adjustable bulkhead spacer element 58. bulkhead spacer element 58 can be adjusted to modify a spacing between the blade assembly 20 and the user's skin.
[070] The attachable comb 50 may further comprise a mounting portion 60 comprising a retaining element 80, particularly a retaining hook. The retaining element 80 may also be called, at least in some embodiments, a resilient retaining element 80. The retaining element 80 may be formed integrally with or mounted to the support structure 52. It is particularly preferred that the retaining element 80 is a deflectable retaining element that can be operated or actuated to selectively lock or disengage the attachable comb 50. A deflection operating movement of retainer 80 is indicated in Figure 12 by a double curved arrow indicated by reference numeral 82 Retaining element 80 may be arranged to cooperate with a mounting contour 90 in housing portion 12.
[071] As can best be seen from Figures 9, 11 and 12, the attachable comb 50 may be further provided with an orientation determining portion 62 which may comprise at least one receiving base 64, which may contact with the top surface 32 of the blade assembly 20 in the assembled state of the attachable comb 50. By way of example, the orientation determining portion 62 may comprise a first receiving base 64 and a second receiving base 64, with reference also to the Figure 10. The at least one receiving base 64 may extend from a top portion 65 of the support rod 54. The orientation determining portion 62 may further comprise at least one lateral guide element 71. Preferably, they are provided a first guide element 71 and a second lateral guide element 71 which are arranged to guide the lateral ends of the blade set 20 so as to define the lateral position (Y position) of the blade set 20. Currently, attachable comb 50 and blade assembly 20 can be completely aligned in the assembled state.
[072] As can best be seen from Figure 11, the receiving base 64 can comprise a longitudinal extension lr that can cover at least a substantial portion of a longitudinal dimension lb of the blade assembly 20. This can basically avoid mounting incorrect attachment of the attachable comb 50, which may include engaging a bottom side (instead of the top surface 32) of the blade assembly. It is, therefore, preferred that the longitudinal coverage of the blade assembly by the at least one receiving base 64 exceeds at least half the length of the longitudinal extent 1b of the blade assembly 20.
[073] Generally speaking, the at least one receiving base 64 can be arranged as a tab or a prong extending from the support structure 52. As can best be seen from Figure 8, the at least one receiving base 64 may be disposed in slots between comb teeth 66 of spacer spacer element 58. Consequently, the at least one spacer spacer element 58 generally does not interfere with comb teeth 66. In some embodiments, the determining portion directional 62 of the spacer spacer member 58 may be, at least sectionally, integrally formed. This applies in particular when the bulkhead spacer element 58 is a non-adjustable bulkhead spacer member 58. In this context, the at least one receiving base 64 can be disposed on a back or bottom side, or on at least some of the comb teeth 66.
[074] The attachable comb 50 may further comprise a handling tab 84, particularly a disengaging handling tab 84. In general, the handle flap can also be called a handle. The handling tab 84 can be disposed on a bottom portion 83 of the support structure 52. The handling tab 84 can be actuated or operated by a user to disengage or release the attachable comb 50 of the hair-cutting apparatus 10.
[075] Still referring to Figures 10 and 11, the retaining element 80 and the mounting contour 90 of an exemplary embodiment according to the present disclosure will be detailed below. Figure 11 shows a cross-sectional view of an attachable comb 50 which is secured to a housing portion 12 of a hair trimming apparatus 10, see also lines XI-XI in Figure 10. The retaining member 80 can be arranged as a deflectable retaining hook. Retaining member 80 can be pivotally mounted to support structure 52. For this purpose, a pivot or a mounting pivot 88 can be provided. Retaining member 80 is rotatable about pivot 88, see double curved arrow indicated by reference numeral 82 in Figure 12. In general, attachable comb 50, particularly support structure 52 thereof, can be adapted to a outer contour of housing portion 12, as illustrated by way of example in Figure 13. Retaining member 80 may comprise a spike 86 which may be configured to engage mounting flange 90 with housing portion 12. Mounting flange 90 may comprising an inclined sliding surface 92 and an engagement surface 94.
[076] As best seen in Figure 13, the sloped sliding surface 92 can be basically oriented outward. The engagement surface 94 can be basically oriented inwardly (relative to the housing portion 12). The engagement surface 94 can also be considered as a locking element of the mounting contour 90. On the engagement surface 94, the tip 86 of the retaining element 80 can be locked. Accordingly, the attachable comb 50 may be locked in the housing portion 12. The attachable comb 50 may further comprise a tension element 100, particularly a spring element 100 for the retaining element 80. The tension element 100 may generally bias the retaining member 80 to engage mounting contour 90. Given the exemplary orientation of attachable comb 50 shown in Figure 11, tension member 100 may apply a rotational force to retaining member 80 which tends to push retaining member 80 for a clockwise rotation. It should be noted in this context that the above term “clockwise” is not to be interpreted in a limiting way, but should instead be regarded as an example of the configuration of the tension element 100 and the holding element 80.
[077] As can best be seen from Figures 13 and 15, the retaining member 80 may further comprise, at the tip 86, a retaining surface 96 and a sliding surface 98. Basically, the sliding surface 98 can be arranged to cooperate with the sliding inclined surface 92 of the mounting contour 90 after inserting the tip 86 of the retaining element 80 into the mounting contour 90. The sliding surface 98 can slide on the sliding inclined surface 92 so that the retaining element 80 can be deflected against the tensioning force of tensioning element 100. Accordingly, point 86 can enter mounting contour 90, where retaining surface 96 can engage with or contact engagement surface 94 to lock retaining element 80 and hence the attachable comb 50.
[078] Additional reference is made to Figure 11. Figure 11 illustrates the attachable comb 50 in the assembled state. In the assembled state, the attachable comb 50, particularly the orientation determining portion 62 thereof, can bring the blade assembly 20 into a preset orientation suitable for trimming. In general, the blade assembly 20 can be coupled to a tension element or spring element 69 that can be secured to or associated with the housing portion 12. The spring element 69 is shown schematically in Figure 11 for purposes of illustration. Further reference is made in this regard to spring element 69 illustrated in Figure 4. In general, spring element 69 may be configured to bias the blade assembly 20 into a predefined neutral pivotal orientation with reference to Figure 14, for example. Consequently, as shown in Figure 11, the orientation determining portion 62 can act against the spring element 69. Therefore, the blade assembly 20 can be held in a locking orientation suitable for trimming in a forced preload state, basically no considerable backlash.
[079] As can be further seen in Figure 11, the tension element 100 can basically pull the orientation determining portion 62 into defined engagement with the set of blades 20. A direction of a locking force that is assignable by the element of tension 100 and applied by retaining member 80 is denoted in Figure 11 by FL. Given the actual orientation of the blade set 20 in the assembled state, with reference to the coordinate system (of the blade set) indicated in Figure 11, the locking force FL can cause, at a top end adjacent to the blade set 20, a resultant holding force FR which basically prevents a release movement of the attachable comb 50 in the X longitudinal direction. Consequently, the attachable comb 50 can be considered as a self-aligning attachable comb 50. The desired locking orientation of the blade assembly 20 can further improve the mating fit of the attachable comb 50. The attachable comb 50 may also be called the self-retaining or self-locking attachable comb 50.
[080] As already mentioned above, the attachable comb 50 can also be provided with a handle or a handling flap 84, which can be integrally formed with and extend from the support structure 52. The user can actuate the handling tab 84 for disengaging the attachable reed 50. A respective driving direction is indicated in Figure 11 by an arrow represented by reference numeral 112. Pushing the handling tab 84 in the disengaging direction 112 can rotate the retaining member 80. Given the configuration example illustrated in Figure 11, the retaining element 80 can be rotated counterclockwise when the handling tab 84 is pushed in the disengagement direction 112. Consequently, the tip 86, particularly the retaining surface 96 ( see Figure 15) of the retaining element 80, can be disengaged from the engagement surface 94. In this way, the retaining element 80 can be released from the engagement with the mounting contour 90. Consequently, the comb is attached. el 50 can be released from the hair trimming apparatus 10. In other words, in at least some embodiments, the attachable comb 50 may be called a single-step release attachable comb 50. Disengagement of retainer 80 may generally involve rolling or sliding retainer 80 over sloped sliding surface 92, which may induce pivotal movement of retainer 80. Consequently, point 86 may span the apex between the sloped sliding surface 92 and the engaging surface 94 of the mounting contour 90.
[081] With specific reference to Figure 14 and Figure 15, a process of assembling the attachable comb 50 will be described in more detail. As can be seen in Figure 14, the blade assembly 20 of the cutter head 18 can assume a basically neutral orientation (see X, Z coordinate axes) when no external force or load is applied to it. The attachable comb 50 can be fed to the hair trimming apparatus 10 in an assembly direction 114. In particular, the orientation determining portion 62 may approach the blade assembly 20. As best seen in Figure 15, the determining portion of the orientation 62, particularly the at least one receiving base 64 thereof, can push the blade assembly 20 towards the locking orientation when the orientation determining portion 62 contacts the top surface 32 of the blade assembly 20 (with reference to the tilted X, Z coordinate axes in Figure 15). A respective rotary movement of the blade assembly 20 is indicated by a curved arrow indicated by reference numeral 116 in Figure 15.
[082] Basically, the set of blades 20 and the at least one receiving base 64 can be brought into alignment after mounting the attachable comb 50. As already mentioned in relation to the embodiment illustrated in Figure 11, the set of blades 20 can be pushed against a spring element 69. However, as can be seen in Figure 15, in yet another embodiment, the blade assembly 20 can be pushed against a restrictor locking element 68. However, this embodiment may still involve an element of spring 69 provided in the blade set. The limiting locking element 68 can be secured to or associated with the housing portion 12. Once the blade assembly 20 is brought into the desired orientation, the attachable comb 50, particularly the support structure 52 thereof, can be placed. in contact with the housing portion 12. This may basically involve rotating or pivoting the attachable comb 50 to bring it into alignment with the housing portion 12; refer to the curved arrow indicated by reference number 118 in Figure 15.
[083] In this way, the retaining member 80 may contact the mounting contour 90 in the housing portion 12. This may involve a sliding contact (also a combined sliding and rotating contact) of the sliding surface 98 with the surface sloped sliding 92, with reference also to Figure 11. Accordingly, retaining member 80 may be deflected (e.g., pivoted about pivot 88) so that sliding surface 98 can overtake sloped sliding surface 92, as indicated by a curved arrow in Figure 15 is indicated by reference numeral 120. In the course of this, the retaining surface 96 can engage the engaging surface 94 on the mounting contour 90. Accordingly, the attachable comb 50 can be aligned with and locked onto the portion of housing 12. This can have the advantage that the user of the device does not have to directly actuate the retaining element 80 to engage the assembly contour 90. Basically, the month This can be applied when the attachable comb 50 is disengaged from the hair-cutting apparatus 10. The retaining element 80 can therefore be called the mediately actuable retaining element 80.
[084] With further reference to Figures 16 and 17, alternative mounting configurations of attachable combs 50 for haircutting apparatus 10 will be illustrated and discussed in more detail. The embodiment illustrated in Figure 16 can basically be called the attachable comb 50 on the back. The attachable comb 50 at the rear may generally correspond to the embodiments illustrated in Figures 8 to 15. The attachable comb 50 at the rear may be called an attachable comb 50 which is attached to a rear side of the housing portion 12 of the hair-cutting apparatus 10. An attachment housing 132 of the attachable comb 50 at the rear is indicated by reference numeral 132 in Figure 16.
[085] Figure 17 illustrates an alternative embodiment of the attachable comb 50. The attachable comb 50 may be called the attachable comb 50 on the front. In other words, the attachable comb 50 of Figure 17 may be attachable to a front side of the hair-cutting apparatus 10 which is opposite the rear portion illustrated in Figure 16. A respective attachment housing 134 which is adapted to a front side of the housing portion 12 of pile cutting apparatus 10 is indicated in Figure 17 by reference numeral 134. Likewise, an attachable comb 50 at the front may be mounted to pile cutting apparatus 10 so that the blade assembly 20 is taken to a preset locking orientation suitable for trimming.
[086] With further reference to Figures 16 and 17, it should further be noted that the at least one receiving base 64 of the orientation determining portion 62 may be generally formed integrally with the comb teeth 66 of the bulkhead spacer element 58. Such an arrangement can be contemplated when using a bulkhead spacer element 58 which is basically non-adjustable with respect to its spacing length. Consequently, the position of the comb teeth 66 relative to the blade assembly 20 is basically fixed in the assembled state. Therefore, the comb teeth 66 can form the receiving base 64 for the top surface 32 of the blade assembly 20. However, when the spacer spacer element 58 whose length is adjustable is used, it may be preferable to provide receiving bases 64 separate that may form the orientation determining portion 62; see also Figure 8 and Figure 9.
[087] Generally speaking, the rear part of the housing of the hair trimming apparatus 10 can be considered as the side to which the top surface 32 of the blade assembly 20 is not facing in the assembled state of the attachable comb 50. generally speaking, the front side of the housing of the hair trimming apparatus 10 can be thought of as the side to which the top surface 32 of the blade assembly 20 faces in the assembled state of the attachable comb 50.
[088] Although the invention has been illustrated and described in detail in the drawings and the aforementioned description, such illustration and description are to be considered illustrative or exemplary, and not restrictive; the invention is not limited to the disclosed embodiments. Other variations to the disclosed embodiments may be understood and made by those skilled in the art in practicing the claimed invention from a study of the drawings, the disclosure and the appended claims.
[089] No reference signs in the claims are to be construed as limiting the scope of the invention.
