FIELD OF THE INVENTION
[001] The present disclosure relates to an adjustment actuator for a comb with adjustable spacing of an apparatus for cutting hair, wherein the adjustment actuator comprises an actuator that is configured to drive a movable portion of the comb with adjustable spacing at relation to a set of blades of the hair-cutting apparatus. The present invention further relates to an adjustable spacing comb comprising an adjustment actuator and a hair trimming apparatus which is provided with an adjustable spacing comb. Furthermore, the present invention further relates to a method for operating an adjustable spacing comb of a hair trimming apparatus. BACKGROUND OF THE INVENTION
[002] Hair trimming apparatus, particularly electric hair trimming apparatus, are well known and may include finishing machines, hair trimmers and razors. Electric hair cutting devices may also be called electrically powered hair cutting devices. The devices for cutting electric hair can be powered by an electrical energy source and/or by energy storage, such as batteries, for example. Electric hair trimming devices are generally used to trim hair on the (human) body, in particular hair and beard, to enable an individual to look well groomed. Electric hair clippers are often used to cut animal hair.
[003] EP 2 322 328 A1 discloses a hair-cutting device having an interchangeable comb unit. The interchangeable comb unit comprises a comb identification element which allows the device to identify a length of hair associated with the comb unit through a comb recognition arrangement present in the device housing.
[004] The document US 2012/0233865 A1 discloses an adjustable comb assembly arranged to be attachable to an electric hair cutting apparatus. The comb assembly comprises a knob that allows the user to rotatably adjust the cutting length setting of the comb assembly.
[005] The document US 6,968,623 B2 discloses a hair trimmer comprising a body, a cutting head including a set of blades, an adjustable comb, the comb being movable in relation to the set of blades, an electric motor to actuate the blade assembly to effect the cutting action and an actuator assembly that is capable of moving the comb relative to the blade assembly between a fully retracted position and a fully extended position, the actuator assembly comprises a comb device , a comb button connected to the comb device, the comb button being operable to adjust the comb position in relation to the blade set, and a movable lock button in relation to the comb button, with the comb button latch selectively prevents and allows movement of the comb knob in relation to the body. Consequently, manual adjustment of the comb length is made possible.
[006] The document US 7,992,307 B2 discloses a hair trimmer comprising a box and a motor that is connected through a shaft to a motorized cutting guide, the cutting guide being driven by the motor. cutting guide is movable to a plurality of guide positions. Consequently, motorized adjustment of the length of the cutting guide (or comb) is made possible.
[007] A comb of a hair-cutting apparatus, particularly a spaced comb, may generally be arranged as an attachable comb or an integrally formed comb. A spaced comb generally separates a set of blades from the skin hair-cutting device when the device moves in a direction of motion relative to the skin during operation. Consequently, the spaced comb may make it possible to cut the hair to a desired length, that is, to a desired length of hair remaining on the skin.
[008] Conventional hair cutting apparatus may be provided with a set of accessory combs, each of which is associated with a distinct hair length. Consequently, a user of the device basically needs to replace one attachable comb with another one to change the cut length. Furthermore, manually adjustable accessory combs are known, as disclosed in US 6,968,623 B2. In addition, motor-equipped tuning combs have recently been introduced, as, for example, disclosed in US 7,992,307 B2. Typically, motor-equipped adjustment combs comprise a movable portion of the comb that is movable relative to a blade assembly of the hair-cutting apparatus, the movable comb portion being coupled to an actuator, particularly an electromotor. and/or an electric propulsion system.
[009] However, it has been observed that operating a motorized adjustment comb often has several disadvantages. It is often impractical for the user to operate the comb with adjustable spacing in a precise and exact manner, as often quite conventional control elements are provided, eg push button, control levers etc. These control elements often provide pre-defined sensitivity to user-entered data. In other words, a single input action by the user can cause a defined motor response such that the adjustable spacing magazine is moved by a defined distance or pitch.
[0010] Consequently, inaccurate positioning of the adjustable spacing comb in the given adjustment range (which may include covering considerably long distances in the adjustment range) can be considered time-consuming. In addition, adjusting the adjustable spacing comb can be difficult as conventional control elements often require considerably large minimum increments of adjustment movement as indicated above. Consequently, operating a motorized adjustable spacing comb by means of conventional control elements can be considered a compromise between the speed of adjustment and the accuracy of the adjustment.
[0011] Due to the lack of operational efficiency and adjustment of the comb arrangements with adjustable spacing mentioned above, the operation of the hair trimming apparatus can be more complicated. Thus, it would be advantageous to simplify the action of adjusting the comb with spacing. It would be additionally advantageous to provide a comb with adjustable spacing and an adjustment trigger, therefore, which can be operated by the user in a way that saves time and is highly accurate.
[0012] Thus, there is still room for improvement. SUMMARY OF THE INVENTION
[0013] It is an object of the present invention to provide an apparatus for haircutting, a comb with adjustable spacing for a haircutting apparatus and an adjustment driver for such a comb with adjustable spacing that can solve at least some of the problems mentioned above . In particular, it is an objective to provide an adjustment trigger for a comb with adjustable spacing that can ensure simplified operability and, more preferably, more options to choose from for a user. It would be additionally beneficial to seek improvements in tuning speed and tuning accuracy and precision. It would be additionally advantageous to provide a corresponding method for operating a comb with adjustable spacing.
[0014] According to a first aspect of the present disclosure, an adjustment actuator for a comb with adjustable spacing of an apparatus for hair cutting is presented, the adjustment actuator comprising: - an actuator that is configured to drive a movable comb portion of the comb with adjustable spacing relative to a blade assembly of the hair-cutting apparatus, - a manually operated rotating element, particularly a manually rotatable rotating element, and - an encoder, particularly a rotary encoder , which is configured to detect the rotational movement of the rotating element and to produce a corresponding user input signal,
[0015] where the actuator is operated based on the data signal entered by the user.
[0016] This aspect is based on the idea that the rotation element, which can also be called a rotating wheel, can enable actions of data entered by the user that can induce a precise positioning and a quick positioning of the mobile portion of the comb. On the one hand, the user can rotate the rotation element slowly and in small (angular) increments. This can allow for accurate positioning of the moving portion of the comb. On the other hand, the user can push or accelerate the rotating element to considerably high speeds of revolution using the moment of inertia of the rotating element. Consequently, the rotation element can still rotate or rotate even if the user no longer touches or comes in contact with the rotation element. When the rotation element is rotating, huge total rotation angles can be obtained. Consequently, the movable portion of the comb can be moved a considerably long distance. On the other hand, the user can slightly rotate the rotating element in order to move the movable portion of the comb in considerably small increments.
[0017] In general, the rotation element can also be called pendulum control element. It is particularly preferred that the rotating element is a rotatably mounted rotating element comprising a considerably large moment of inertia. It is particularly preferable that this rotation element, after being accelerated by the user, can adopt a pendulum-like behavior. In other words, kinetic energy can be stored in the pendulum-like rotating element which can basically cause the rotating element to rotate even further when the user releases or loses contact with the rotating element.
[0018] In general, the user can operate the rotating element with fingers or thumbs. For example, the user can accelerate or rotate the rotating element by pushing or pulling a portion of the circumference of the rotating element.
[0019] The adjustment drive, according to the above aspect, can have the additional advantage that a single rotation element can be used to extend or retract the movable portion of the comb. Basically, the rotating element can rotate clockwise or counterclockwise. Consequently, the rotation can be "translated" into an extension or retraction movement of the movable portion of the comb.
[0020] In general, the encoder can be configured to detect the angular movement, the angular velocity and/or the angular acceleration of the rotating element. Consequently, positioning speed, positioning distance, target positions etc. they can be specified by the user in wide ranges by, respectively, the operation or rotation of the rotating element.
[0021] In general, the encoder can be configured to produce an electrical signal from user-entered data that can take the form of an analog signal or digital signal. The encoder can be arranged as an absolute encoder or an incremental encoder. The encoder can be arranged as an optical encoder and/or a capacitive encoder, for example.
[0022] The adjustment actuator, according to the first aspect of the present invention further comprises a control unit coupled to the actuator and the encoder, the control unit being configured to convert the data signal entered by the user into a signal of actuator operation. To that end, the tuning trigger can use a conversion algorithm. Alternatively or additionally, the tuning trigger may use characteristic mapping comprising respective pairs of user-entered data signal values and corresponding actuator operating signal values.
[0023] By way of example, when the encoder is arranged as an absolute encoder, a different rotation angle of the rotation element can be associated with a different absolute position of the movable portion of the comb in relation to the set of blades. It is worth mentioning in this sense that the encoder can be arranged as a single-turn encoder or a multi-turn encoder.
[0024] In yet another embodiment, the encoder can be arranged as an incremental encoder. In other words, the encoder can be arranged as a relative encoder. An incremental encoder can be configured to detect incremental (rotary) position changes of the rotating element. Consequently, incremental changes in the position of the movable portion of the comb can consequently be induced. It also goes without mentioning that a combination of absolute or incremental spin detection can be used by the encoder and the respective control unit.
[0025] In some embodiments, the rotation element may be arranged as a multi-turn rotation element. Consequently, no limit lock for swivel movement is provided. However, in some alternative embodiments, the rotating element may cooperate with respective limit locks that limit a maximum rotational movement of the rotating element.
[0026] The adjustment actuator control unit, according to the first aspect of the present disclosure, is configured to operate the moving portion of the comb such that an adjustment speed of the moving portion of the comb is a function of a difference between a normalized position of the rotating element and a normalized position of the movable portion of the comb. This function can be a proportional relationship or a non-linear relationship, such as an exponential or quadratic relationship, for example. Consequently, the angular displacement of the rotating element can be used to set the speed of adjustment of the moving portion of the comb. Alternatively, the angular speed of the rotating element can set the speed of adjustment of the moving portion of the comb. The position of the rotating element and the position of the movable portion of the comb can be normalized so that they are comparable.
[0027] The above modality can also be detailed in the sense that the control unit is configured to operate the moving comb based on the following formula:

[0028] where Vpente is the speed of adjustment of the moving portion of the comb, where Kganho is a factor or gain coefficient, where Xroda is the rotating position of the rotating element and where Xpente is the position of the moving portion of the comb.
[0029] As indicated above, the algorithm can use absolute positions and/or relative positions. It may also be preferable to define the speed limits resulting from the movable portion of the Vpente comb. For example, a speed range can be provided that comprises an upper or lower edge [minimum speed, maximum speed]. Consequently, the Vcomb adjustment speed of the moving portion of the comb can be set to fall within the following range:

[0030] Consequently, actuator overloads (or tuning actuator overloads) can be avoided.
[0031] In general, the detection of user inputs and, consequently, the operation of the actuator can be carried out according to the following procedure: Initially, the user moves or rotates the rotating element. Consequently, the encoder detects the angular movement of the rotating element. Consequently, the control unit can detect a resultant difference between the (rotating) position of the rotating element and the actual position of the comb. Thus, the above formula (or a similar one) can be applied to calculate the speed of the resulting comb adjustment in response to the data entered by the user. Consequently, the actuator can be operated so as to drive the comb with adjustable spacing at the calculated setting speed. The adjustment action of the comb may stop when the control unit determines that the (normalized) position of the rotating element matches the (normalized) position of the movable portion of the comb.
[0032] In yet another embodiment, the rotation element is a pendulum rotation element, the rotation element further comprising a circumferential portion that is tangible to a user. Consequently, the user can touch, particularly, push or pull, the circumferential portion so as to set the rotating element in rotation.
[0033] In yet another embodiment, the rotating element is a high density rotating element comprising a significant moment of inertia. By way of example, the rotating element can be formed from a material which can comprise a considerably high bulk density. For example, the circumferential portion of the rotating element may be formed from metal material and/or rubber material or rubber-like material. In general, mass can be accumulated in the circumferential portion of the rotating element. In other words, material can be removed in a central portion of the rotating element.
[0034] In one embodiment, the rotation element of the adjustment actuator is rotatably mounted on the hair-cutting apparatus, particularly, rotatably supported in a housing portion of the hair-cutting apparatus. In general, it is preferred that the rotating element is mounted such that, relative to the housing portion of the hair-cutting apparatus, such smooth rotational movement of the rotating element is made possible. The above embodiment can be further developed in the sense that the swivel element is at least partially covered by the housing portion, a circumferential portion of the swivel element being accessible through an opening portion of the housing portion. Consequently, the rotating element can be perceived by the user as an integral component of the hair-cutting apparatus, particularly of the housing portion thereof. In some embodiments, a pivot element locking member may be provided which selectively locks the pivot element relative to the housing portion.
[0035] In yet another embodiment, the rotating element may comprise a circumferential surface pattern, particularly a circumferential knurling. By way of example, the so-called cross-line pattern can be generated in the circumferential portion. Knurling can involve linear knurling, rhomboid knurling, and other types of knurling. Basically, knurling allows the user to better grip the rotation element. Consequently, the user can push or set the rotation element to an even higher rotation speed. Also, the precise operation of the rotating element can be simplified in this way.
[0036] Alternatively, a better grip of the rotating element for the user can also be obtained by supplying material in the circumferential portion which comprises considerably high coefficients of friction. By way of example, rubber material or rubber-like material can be provided in the circumferential portion which can exhibit considerably high frictional forces.
[0037] In yet another embodiment, the tuning trigger is further configured to provide feedback to a user, with a type of feedback being selected from a group consisting of tactile feedback, audio feedback, visual feedback and combinations thereof.
[0038] By way of example, feedback can be provided to the user through a vibrating alert. The corresponding vibrations can be generated by the actuator itself or by a separate vibrating element. Audio feedback can be provided to the user through a buzzer or similar element. Visual feedback can be provided to the user by the comb itself with adjustable spacing as the movable portion of the comb is generally displaced by distances that are clearly visible to the user. However, separate visual indicator elements can also be considered, for example, active display elements.
[0039] According to another aspect of the present disclosure, a comb with adjustable spacing for an apparatus for cutting hair is disclosed, wherein the comb with adjustable spacing comprises a movable portion of the comb that is movable with respect to a portion of housing the hair-cutting apparatus and an adjustment actuator in accordance with at least some of the embodiments discussed herein. In general, the spaced comb can be arranged as a fixable and removable spaced comb. Alternatively, the spaced comb can be arranged as a spaced comb supplied integral or integrally, which cannot be removed from the hair trimmer. The movable portion of the comb may comprise a plurality of comb teeth that can divide and guide the hair when the hair cutting apparatus including the comb with adjustable spacing is moved by the hair to cut the hair to a selected length.
[0040] In yet another aspect of the present disclosure, an apparatus for cutting hair, particularly a finishing machine or hair trimmer, is disclosed, wherein the apparatus for cutting hair comprises a housing portion, a cutting unit. , including a blade assembly, and an adjustable spacing comb, in accordance with at least some of the embodiments described herein. In general, the hair-cutting apparatus can be considered as an electrically motor-equipped hair-cutting apparatus. Consequently, a motor can be provided to drive the set of blades. Generally, the blade assembly may comprise a stationary blade and a mobile blade, the mobile blade being movable relative to the stationary blade. The movable blade can be driven relative to the stationary blade, particularly oscillatingly driven. The movable blade and the respective stationary blade may comprise cutting edges which can cooperate to cut the hairs.
[0041] In general, the hair-cutting apparatus may comprise an elongated box comprising a first end and a second end that is opposite the first end. At the first end of the box, a cutting head can be arranged. The second end of the box may also be called the cable end.
[0042] In one embodiment of the hair-cutting apparatus, the rotating element is mechanically decoupled from the actuator of the adjustment actuator. This may particularly involve the rotating element being mounted in a pivotal manner independent of the actuator. In other words, the rotating element is not mechanically connected to the actuator. It goes without saying that the rotating element and the actuator can be coupled through the housing of the hair trimmer. However, despite being arranged in or connected to the housing portion, the rotating element and the actuator of the adjusting actuator can be mechanically independent of each other. In other words, signal lines or signal links for communication between the rotating element and the actuator can be provided. For example, the rotating element and the actuator can be coupled via the control unit and the encoder.
[0043] In yet another embodiment of the apparatus for hair cutting, the rotating element is disposed at a location of the housing portion that is remote to the comb adjustment actuator with adjustable spacing. This can have the advantage that the rotating element can basically be arbitrarily positioned in the housing portion of the hair trimmer without the great need to take into account the actual arrangement and/or configuration of the actuator. Consequently, the rotating element can be arranged in a user-friendly location of the housing portion which can further simplify the operation of the hair-cutting apparatus.
[0044] According to another aspect of the present disclosure, a method is presented for operating a comb with adjustable spacing for an apparatus for hair cutting, the method comprising the following steps: - providing an adjustment actuator comprising a actuator for driving a movable portion of the comb of the comb with adjustable spacing, - providing a manually operated rotating element, particularly a manually swivelable rotating element, and - detecting the rotational movement of the rotating element, wherein the rotational movement is induced by moving user-entered data, - generating and providing a respective user-entered data signal, and - operating the actuator in accordance with the user-entered data signal.
[0045] Preferably, the method can use the comb with adjustable spacing and the adjustment trigger, as discussed herein. Preferred embodiments of the disclosure are defined in the dependent claims. It is to be understood that the claimed method has preferred embodiments similar and/or identical to the claimed device and as defined in the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] Figure 1 shows a schematic perspective view of a lint-cutting apparatus 10, particularly an electrically operated lint-cutting apparatus 10. The lint-cutting apparatus 10 may also be called a hair trimmer or cutter . The pile cutting apparatus 10 may comprise a housing or housing portion 12 having a generally elongated shape. At a first end thereof, a cutting unit 14 can be provided. The cutting unit 14 may comprise a blade assembly 16. The blade assembly 16 may comprise a movable blade and a stationary blade that can move with each other to cut hair. At a second end of the housing portion 12, a handle or handle portion 18 can be provided. A user can squeeze or hold the box 12 in the handle portion 18.
[0060] The hair trimming apparatus 10 may additionally comprise operator controls. For example, an on-off switch or button 20 can be provided. In addition, a length adjustment control 22 may be provided in the box 12 of the hair trimming apparatus 10. The length adjustment control 22 may be provided if an adjustable spacing comb 26 is attached to the box 12 of the cutting apparatus. 10. In Figure 1, the adjustable spacing comb 26 is shown in a removed or released state. When the spaced comb 26 is removed from the pile cutting apparatus 10, a minimum cut length can be obtained. When the spacing comb 26 is attached to the pile cutting apparatus 10, the piles can be cut to a desired length.
[0061] Figure 2 shows a schematic perspective illustration of a first end of a housing portion 12 of a hair-cutting apparatus 10. In addition, an adjustable spacing comb 26 is shown in an insert orientation. By way of example, the spaced comb may comprise an attachment portion 28 which may comprise, for example, sliding supports 34-1, 342. The attachment portion 28 may engage the housing portion 12. fixture 28 can be inserted into respective slots in a mounting portion 30 of housing portion 12. Sliding brackets 34-1, 34-2 can be inserted into respective slots in mounting portion 30. fixture portion 28 may further comprise at least one engaging member 36. The engaging member 36 can hold the spaced comb 26 in its assembled state.
[0062] As can be further seen in Figure 2, the spaced comb 26 may further comprise a toothed portion 32 including a plurality of teeth of the comb. In general, the teeth of the toothed portion 32 can comprise a slot in which the blade assembly 16 can be movably disposed in the fixed state.
[0063] With further reference to Figure 3 and Figure 4, an exemplary embodiment of an adjustable spacing comb 26 and an exemplary embodiment of an adjustment trigger 50 of a spacing comb 26 are further illustrated and described. Figure 3 shows a schematic rear view of a lint-cutting apparatus 10. Figure 4 shows a schematic side view of a lint-cutting apparatus 10. It is worth mentioning in this regard that these views shown in Figure 3 and in Figure 4 do not necessarily represent the same disposition or modality. Respective box portions 12 of pile cutting apparatus 10 are indicated in Figure 3 and Figure 4 by dashed lines. Consequently, the internal components of the pile cutting apparatus 10 are visible.
[0064] With specific reference to Figure 3, the adjustable spacing comb 26 is further described. The adjustable spacing comb 26, also referring to Figure 1 and Figure 2, may comprise slide supports 34 which can cooperate with a device 42 which is disposed in housing 12. In general, a snap-in assembly of slide supports 34 in the device 42 can be provided. At least a substantial portion of the spaced comb 26 can be considered a movable portion of the comb 40. As best seen in Figure 3, the movable portion of the comb 40 can be coupled to the device 42 and consequently displaced with the device 42. driving device 42 and the movable portion of the comb 40, an engaging member 44 may be provided which is coupled to the device 42. To operate or drive the movable portion of the comb 40 with respect to the blade assembly 16 (see Figure 1). , an adjustment actuator 50 may be provided which may also be called an adjustment propulsion system. In other words, the tuning actuator 50 can be considered a motorized tuning actuator 50.
[0065] The adjustment actuator 50 may comprise an actuator 52, or more particularly, an electromotor. The filter actuator 52 can be coupled to a reduction gear 54. The reduction gear 54 can be coupled to a transmission element 56. In general, the transmission element 56 can be arranged to convert a rotary output movement of the actuator 52 and the reduction gear 54, if any, in a basically longitudinal positioning movement of the movable portion of the comb 40. A respective longitudinal direction is indicated in Figure 3 and in Figure 4 by a double arrow represented by the reference numeral 58.
[0066] As can be seen in Figures 3 and 4, the transmission element 56 can be arranged as a filament spindle, particularly a small pitch spindle. Accordingly, the transmission element 56 can be arranged to be configured in pivotal movements, see the curved arrow represented by reference numeral 60 in Figure 3. The transmission element 56 can be configured to engage the engagement element 44 so as to push. or pulling the device 42 and, consequently, the movable portion of the comb 40. In some embodiments, the transmission element 56 may be arranged as a rack element. In some embodiments, transmission element 56 may be arranged as a connecting rod element. In general, the actuator 52 can be mechanically connected to the device 42 and, in the assembled state, to the movable portion of the comb 40.
[0067] To operate the tuning trigger 50, respective control elements can be provided. To that end, the adjustment actuator 50 may comprise an input rotation element 64, particularly a manually operable rotation element 64. In general, the rotating element 64 can be formed basically in a symmetrical swivel shape. The rotating element 64 can be pivotally mounted. More particularly, the rotating element 64 may be mounted to the housing portion 12 or to an intermediate member that is secured to the housing portion 12. In general, the rotating element 64 may be arranged to be rotated about an axis of rotation 66, see also the double curved arrow represented by reference numeral 68 in Figure 3. A user may operate or drive the rotation element 64 so as to control the adjustment driver 50 and thereby adjust the movable portion of the comb 40 to a desired cut length.
[0068] The rotating element 64 may be called the flywheel rotating element 64. The rotating element 64 may have a considerably high moment of inertia. Consequently, the user can configure the rotation element 64 to rotate. Due to the moment of inertia, the rotating element 64 can basically maintain its rotation for a considerable period of time. Consequently, a user can push or pull the rotating element 64, which can involve a single actuation pressure. The rotating element 64 can then rotate "passively" for a considerably longer period of time.
[0069] The rotating element 64 is coupled to an encoder 70. The encoder 70 can be configured to detect rotational or rotational movement of the rotating element 64. By way of example, the encoder 70 may comprise a Hall effect sensor or a similar common rotation sensor. Consequently, the encoder 70 can detect and produce a user signal that is derived from the user drive pressure applied to the rotating element 64. The user-entered data signal can be transferred to a control unit 74. The control unit 74 may comprise a processing unit. The control unit 74 can convert the detected user input data signal into an actuator operating signal which can be transferred to the actuator 52. Consequently, there is no power transmission or power transmission link between the actuator 52 and the rotating element 64. Instead, electrical signals can be transferred from encoder 70 to actuator 52 via control unit 74.
[0070] The rotation element 64 can extend into the range of possible user input data that can be detected by a single operating element. As indicated above, the user can, on the one hand, precisely rotate the rotating element for precise positioning of the movable portion of the comb 40. On the other hand, the user can vigorously actuate the rotating element 64, which can cause significant rotation. of the rotating element 64. Consequently, the movable portion of the comb 40 can cover long distances. In each case, the adjustment act is user-friendly and time-saving.
[0071] Further reference is made to Figure 4. An extracted state of the movable portion of the comb 40' is indicated in Figure 4 by a respective dashed line. As can be seen further in Figure 4, a substantial portion of the rotating element 64, particularly a substantial circumferential portion, may be covered by the housing 12 of the lint-cutting apparatus 10. Consequently, a smaller circumferential portion of the rotating element 64 can be accessible to the user. As can be seen further from Figure 4, the rotating element 64 may comprise a circumferential mass accumulation 76. This may increase the moment of inertia of the rotating element 64.
[0072] With specific reference to Figures 5 and 6, other exemplary arrangements of location sensing units for pile cutting apparatus 10 are illustrated and further described. With regard to design and general arrangement, the pile cutting apparatus 10 of Figures 5 and 6 can basically correspond to the pile cutting apparatus 10 illustrated in Figure 3. In Figure 5, the axis of rotation 66 of the rotating element 64 is generally parallel to or only slightly inclined with respect to a longitudinal extent of the elongated housing portion 12 of the lint-cutting apparatus 10. In general, housing portion 12 may extend from a first end and a second end which is opposite to the first end. At a second end of the housing portion 12, a spaced comb 26 can be attached. The second end of the housing portion 12 may also be called the cable end. The axis of rotation 66 may, at least partially, extend through an opening in the housing portion 12.
[0073] Similarly, the axis of rotation 66 of the rotating element 64 shown in Figure 6 is generally parallel or only slightly inclined with respect to a longitudinal extent of the elongated housing portion 12. In Figure 6, the rotating element 64 itself. forms a cable end of the housing portion 12. Accordingly, the cable end (formed by the rotating element 64) can be placed in rotation relative to the (remaining) housing portion 12, note a curved arrow represented by the reference numeral 68. The rotating element 64 of Figure 6 is generally arranged as a rotatable paraboloid or, more generally, as a rotatably symmetrical rotating element 64. However, in at least some embodiments, the rotating element 64 may be at least slightly flattened or similarly deformed.
[0074] In this regard, further reference is made to Figure 7. Figure 7 shows a simplified perspective illustration of a box surface 62 of a box housing portion 12 of an apparatus for cutting hair 10, see also Figure 4. The box surface 82 may comprise an opening or hole 84. Only a relatively small circumferential portion of the rotating element 64 can extend through the opening 84. A respective circumferential portion 86 that is accessible to the user is indicated in the Figure. 7 by reference numeral 86. In general, the rotating element 64 may comprise an anti-skid surface 88. In particular, the rotating element 64 or at least a circumferential portion 86 thereof may be formed of a material that provides a high coefficient of friction. Alternatively, the circumferential portion 86 of the rotating element 64 may be coated with a respective high friction material. By way of example, rubber or rubber-like materials have considerably high coefficients of friction.
[0075] Figure 8 shows a schematic view of a swivelly mounted rotating element 64 that is coupled with an encoder 70, particularly a rotary encoder 70. In some embodiments, the rotating element 64 may comprise a cylindrical or shaped shape. a tube shape. In general, the rotating element 64 may comprise a swivelly symmetrical shape. At the circumferential portion 86 of the rotating element 64, a structured pattern 90, particularly a knurling pattern, may be provided. In general, a number of recesses and/or notches may be provided in the circumferential portion 86 which can improve grip for the user. The knurling may involve rhomboid knurling, linear knurling or similar shapes.
[0076] As shown in Figure 8, the rotating element 64 can be coupled to a rod or shaft 66 that is mounted to at least one bracket 92-1, 92-2 to rotate, see the curved arrow represented by the reference number 68 in Figure 8. Via shaft 66, rotating element 64 can be coupled to encoder 70. Encoder 70 may comprise a wheel 96 that can rotate rotating element 64. In addition, a detector or transceiver 98 may be provided. which detects the rotational movement of the wheel 96 and therefore of the rotating element 64. It goes without saying that the detector or transceiver 98 may also be configured to directly detect rotational movement in the rotating element 64 itself.
[0077] In yet another embodiment, the rotating element 64 may be further coupled to a latch mechanism 102. The latch mechanism 102 may comprise a wheel 104, particularly a polygonal wheel or a sprocket 104. The wheel 104 may be mounted on axle 66 and may be additionally arranged to cooperate with a latch element 106, particularly a latch spring. Latch element 106 can be coupled or mounted to housing portion 12, see also Figures 3 to 7. Locking portion 106 can engage wheel 104. During rotation of rotating element 64, wheel 104 can also rotate. with respect to the latch element 106. Accordingly, the latch element 106 may alternatively engage and disengage respective protuberances and notches in wheel 104. This may cause respective clicking noises. Latch mechanism 102 can additionally inhibit excessive rotational movement of rotating element 64. This can be beneficial to ensure that rotating element 64 stops within respective time limits.
[0078] With further reference to Figure 9 and Figure 10, various positions of the rotating element 64 in the housing portion 12 of the hair-cutting apparatus 10 are described. Figure 9 illustrates a perspective view of a hair-cutting apparatus 10 held by a user. The user can operate the rotation element 64 with the thumb. As can be seen further in Figure 9, the rotating element 64 may comprise an axis of rotation 66 which is basically perpendicular to an overall elongation direction of the housing portion 12. The operation of the rotating element 64 and hence the actuator of adjustment 50 (covered by box 12 in Figure 9) can induce a respective extraction or retraction of the comb with adjustable spacing 26 which is fixed to box 12, see also the double arrow represented by reference number 58 in Figure 9 and Figure 10.
[0079] As can be further seen in Figure 9, the rotating element 64 is arranged in a position of the housing portion 12 which may also be called the central position. In contrast, Figure 10 illustrates an arrangement of a respective rotating element 64 in a position of the housing portion 12 which may be called the lower portion and/or the portion which is close to the second end of the housing portion 12. As no attachment mechanical (force transmission) is required between the rotating element 64 and the actuator 52 of the adjusting actuator 50 (not shown in Figures 9 and 10), the rotating element 64 may be disposed at arbitrary positions of the housing portion 12.
[0080] Figure 10 further illustrates an alternate arrangement or an alternate orientation of a rotating element 64a which is indicated by dashed lines. A respective axis of rotation 66a may be generally parallel to or only slightly inclined with respect to a main longitudinal extent of housing portion 12. Rotation element 64a may be mounted on housing portion 12 and at least slightly extend across. an opening in housing portion 12. Rotation element 64a is operable for rotation relative to housing portion 12, see curved arrow represented by reference numeral 68a in Figure 10.
[0081] Still referring to Figure 11, an exemplary method of operating a comb with adjustable spacing for an apparatus for hair cutting is illustrated and further described. The method may comprise a step S10 which may involve providing an adjustment driver comprising an actuator for driving a movable comb portion of an adjustable spacing comb of a hair trimming apparatus. Preferably, the adjustment trigger is formatted in accordance with at least some of the embodiments presented in the present invention. An additional step S12 may follow, which involves providing a manually operable rotating element, particularly a manually rotating rotating element, which is at least partially accessible to a user through an opening in a housing portion of the apparatus for cutting off. by the. An additional step S14 may follow which may involve detecting user-entered data, particularly the rotational movement of the rotating element which is induced by a movement of user-entered data such as accelerating input pressure. In a subsequent step S16, based on the rotary movement, a respective user-entered data signal can be generated and provided for further processing. In yet another step S18, the actuator of the tuning trigger can be operated based on the data signal entered by the user. Step S18 may involve converting the user-entered data signal into an actuator operating signal. For this purpose a control unit can be provided.
[0082] Figure 12 illustrates several steps of a simplified algorithm for detecting user inputs and for operating a movable comb portion of a comb with adjustable spacing in accordance with the detected user inputs. A first step S20 may involve an action of user-entered data, particularly a triggering of a rotation element by the user. A further step S22 may follow, which may involve detecting that a (normalized) position of the rotating element relative to a (normalized) position of the movable portion of the comb has been changed. As indicated above, the position of the rotating element and the position of the movable portion of the comb can be normalized to make them comparable. For example, a normalized position range can comprise values between 0 and 1.
[0083] In another step S24, a desired movement speed of the moving portion of the comb in response to detected user-entered data can be calculated. Consequently, an operational signal can be generated which can be used to operate an actuator to move the moving portion of the comb. A further step S26 can follow which can stop the movement of the moving portion of the comb when it is determined that the actual (normalized) position of the moving portion of the comb corresponds to the (normalized) position of the rotating element. Steps S20 and S26 can form a loop.
[0084] Although the invention has been illustrated and described in detail in the drawings and in 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.
[0085] No reference signs in the claims are to be interpreted as limiting the scope of the invention.
