Field of invention
[001] The present invention relates to a device for trimming hair and beard with an attachable comb that can be attached to the housing of the device for trimming hair and beard. The present invention relates, in particular, to a hair and beard trimming device with a memory function that allows users to store their favorite length definition and quickly change the length definition by selecting a memory entry. Background of the invention
[002] Electric hair clippers are well known and include trimmers, clippers and shavers or shavers powered by batteries or electricity supplied by the mains. Such devices are generally used to trim body hair, in particular hair and beard, to enable an individual to have a well-groomed appearance.
[003] Commonly, conventional devices for cutting hair and beards comprise a main body forming an elongated housing that has a front or cutting end (here called the "distal end") and an opposite cable end. A cutting set is arranged at the distal end. The cutting set generally comprises a stationary cutting blade with a stationary cutting edge and a mobile cutting blade with a mobile cutting edge. The mobile cutting blade moves reciprocally against the stationary cutting blade. The cutting set is, in general, fixed in a single position in relation to the beard and hair trimmer housing, so that the orientation of the cutting set is determined by a user who guides the housing or the main body of the cutting device. trimming of hair and beard. The stationary cutting edge and the mobile cutting edge are arranged in the tip portions of the stationary cutting blade and the mobile cutting blade, respectively. Generally, these cutting edges protrude from the front side of the device housing for hair and beard trimming, so that the cutting edges are always visible to the user. This makes it easier for the user to see exactly where the hair and beard are cut, which is particularly beneficial when the hair and beard trimmer is used to form and create precise contours in the hair and beard.
[004] As there is a great demand for hair and beard cutting devices that offer the possibility of being used for different cutting lengths, many known hair and beard cutting devices make use of different attachments of different sizes. These attachable combs are, in general, mounted on the distal end of the beard and hair clipper to position the cutter set in relation to the skin. In other words, such an attachable comb is used as a guide that moves over the skin and guides the beard and hair in the direction of the cutting set. In general, the attachable comb is mounted on the cutting set and moves the cutting blades away, in particular their cutting edges (the stationary cutting edge and the mobile cutting edge), in the direction opposite to the skin surface from where the hair and beard hair extends. However, the need to replace the attachable comb with a different one, whenever the length of the cut of the hair and beard requires, can be impractical for the user, since this is not only a time-consuming process, but also requires that the user to keep a stock of several attachments of different sizes.
[005] Thus, many prior art hair and beard cutting devices use a single attachable comb that can be adjusted in different positions in relation to the housing of the beard and hair trimmer device. Users can then adjust the attachable comb in different positions to obtain different lengths of cut hair and beard. Typically, these movable attachable combs can be adjusted between the 3 mm, 5 mm, 7 mm, 9 mm haircut and beard length, in general, up to 12 or 15 mm. Most prior art hair and beard trimming devices that use such movable attachable combs provide a mechanical solution for moving the attachable comb in relation to the hair and beard trimming device housing. Users can thus exchange the attachable comb manually between the different positions.
[006] The document US 2012/0233866 A1 discloses a device for trimming hair and beard with an adjustable attachment comb, the position of the attachment attachment can be adjusted by means of an electric motor. This motor can be controlled through a touch screen that is integrated into the housing of the device for trimming hair and beard. The user can, in this way, change the attachable comb between the different positions with the use of two buttons on the touchscreen, a button to move the attachable comb in relation to the cutting set to increase the length of the hair and beard cut , and the other button to move the attachment comb in relation to the cutting set to decrease the cutting length. This facilitates handling for the user compared to mechanically adjustable attachable combs. However, users sometimes still have trouble correctly adjusting the electronically attached comb. Changing from a very short hair and beard length to a very long hair and beard length can also sometimes seem tedious and could take a long time.
[007] Thus, there is still room for improvement. Summary of the invention
[008] It is an objective of the present invention to provide a hair trimming device that solves the problems mentioned above. In particular, it is an objective to provide an improved hair and beard trimming device with an attachable comb that can be attached, and handling to adjust the attachable comb in different positions is facilitated for the user.
[009] In accordance with an aspect of the present invention, a device for trimming hair and beard is provided which comprises: - a housing; - a cutting set for trimming hair and beard; - an attachable comb that can be attached to the housing; - a drive unit for moving the attachment comb in relation to the cutting set between different comb positions in order to define a hair and beard cut length; - a control unit for controlling the drive unit; - a memory unit; and - a user interface that is configured to receive, from a user, a first memory input indicative of a first comb position and to send a first memory signal to the control unit in response to the receipt of the first memory input , the user interface being configured to receive, from the user, a first recovery input indicative of the first comb position and to send a first recovery signal to the control unit in response to the receipt of the first recovery input, being that the control unit is configured to store position information related to the first comb position on the memory unit in response to receiving the first memory signal, and that the control unit is configured to retrieve position information related to the first comb position of the memory unit in response to receiving the first recovery signal and to control u drive unit to move the attachable comb to the first position of the comb according to the position information related to the first position of the comb.
[010] It should be noted that the word “first (a)”, used in the terms “first memory entry”, “first comb position”, “first memory signal”, “first recovery entry” and “first recovery signal ”in the claims, it should not suggest any temporal significance or chronological order, but should only help to distinguish between different memory entries, comb positions, memory signals, recovery entries and recovery signs.
[011] The hair and beard trimming device shown allows the adjustment of the attachment comb between different positions of the comb by means of a drive unit that can include an electric motor, similar to that realized in the hair and beard trimming device known together to US 2012/0233866 A1. The hair and beard trimming device shown, however, does not only allow the movement of the comb attachment between different comb positions “manually” through the use of a user interface that can include one or more buttons to control the drive unit , but it also allows the user to store their favorite length definitions and retrieve those length definitions, if necessary. The hair and beard trimming device shown is equipped with a memory unit in which the different length settings that the user prefers can be stored. The user can control the device for hair and beard trimming through a user interface that can include one or more buttons, a touch panel or a touch screen. This user interface is preferably arranged in or inside the housing of the device for trimming hair and beard.
[012] The memory function of the device for trimming hair and beard presented allows the user to quickly change the position of the comb to define the length of the cut of hair and beard that he prefers. The user only has to retrieve the position information related to the desired comb position next to the memory unit through an interaction with the user interface, for example, by pressing a button. The control unit will then retrieve the stored position information related to the comb position of the memory unit and control the drive unit to move the attachable comb to said comb position. The attachable comb can therefore be automatically placed in the preferred position of the comb with just one click of the user. In other words, the user no longer needs to adjust the position of the comb alone until the favorite length setting is reached.
[013] The presented hair and beard trimming device is especially advantageous, since the inventors of the present invention have understood, from product studies, that most users generally use only a limited number of length definitions provided by the device for hair and beard trimming. If these favorite length settings can be stored on the memory unit by the user himself, the user can, so to speak, program the device for trimming hair and beard according to his personal needs. The daily handling of the device for trimming hair and beard is, therefore, much more comfortable and faster for the user.
[014] The preferred embodiments of the invention are defined in the dependent claims.
[015] According to a modality, the user interface comprises a first button or first input field to receive, from the user, the first memory entry as well as the first recovery entry, in which the user interface is configured to send the first memory signal to the control unit if the first button or the first input field is activated for a predetermined first period of time, and where the user interface is configured to send the recovery signal to the control unit control whether the first button or the first input field is activated for a second predetermined period of time.
[016] In other words, the same button or input field (that is, the first button or the first input field) can be used to store a desired comb position (that is, the first comb position) on the unit of memory as well as to retrieve said comb position again from the memory unit in order to move the attachable comb to said comb position by means of the drive unit. This facilitates handling for the user, since he can control the complete memory function with just one button or input field.
[017] The term "button" should suggest a "real" physical button, while the term "input field" should suggest a virtual button that can, for example, be provided on a touchscreen.
[018] The device control unit for hair and beard trimming is configured to distinguish whether the user wants to store a new comb position in the memory unit or retrieve an older comb position from the memory unit by identifying the duration that the first button or first input field is activated by the user. If the first button or input field is activated for a first predetermined period of time, the currently defined comb position will be stored in the memory unit. If the first button or first input field is activated by the user for a second period of time, the control unit will retrieve the stored comb position from the memory unit and activate the drive unit to move the attachable comb to the comb position. stored in the memory unit.
[019] According to a preferred embodiment, said second predetermined period of time is shorter than the first predetermined period of time. In other words, if the user activates the first button or first input field, for example, for 1 second or more (first predetermined period of time), the first memory signal will be generated, so that the control unit stores, for in turn, the position information related to the comb position defined in the memory unit. If, on the other hand, the first button or first input field is activated, for example, for less than 1 second (second predetermined period of time), for example, by pressing or clicking only the first button or first field input, the first recovery signal will be generated so that the control unit retrieves the previously stored comb position information from the memory unit in turn and controls the drive unit to move the attachable comb to the position of the comb retrieved according to the position information stored in the memory unit. The user can thus save a new comb position by simply pressing the first entry button or input field for a longer time, while the user can retrieve a stored comb position in order to set the attachable comb in position stored by simply clicking on the first button or first input field.
[020] Alternatively, the user interface may comprise (i) a first button or first input field to receive, from the user, the first memory input and (ii) a second button or second input field to receive, from the user , the recovery entry. In other words, the user interface in this case comprises at least two buttons: a button to store a new comb position and another button to retrieve the stored comb positions and that automatically moves the attachable comb to the position of the comb. recovered comb.
[021] According to an additional modality, the user interface comprises a screen that is configured to display the position information related to an actual position of the comb and / or the position information related to the first position of the comb in response to the receipt of the first recovery entry.
[022] This screen provides the user with feedback on the actual position of the comb that is currently defined. As soon as the user retrieves a stored comb position from the memory unit via the user interface, the screen can be configured to switch from displaying the actual comb position to displaying the stored comb position. This is especially advantageous if the memory unit comprises a memory bank with a plurality of memory locations, as will be elucidated in detail below.
[023] According to an additional modality, the device for trimming hair and beard additionally comprises a feedback actuator that includes at least one of an optical, acoustic or tactile actuator, in which the control unit is configured to activate the actuator feedback in response to the fact that the position information related to the first position of the comb is stored in the memory unit.
[024] In this case, the user receives feedback that the comb position information has been successfully stored in the memory unit. As soon as the user receives said feedback, he can interrupt the activation of the first button or first input field, that is, the user can release the first button or first input field.
[025] The feedback actuator can be implemented in several ways. The same can be a part of the screen, so that, for example, a symbol blinks to assure the user that the desired comb position / haircut and beard length setting has been stored in the memory unit. Alternatively, a small loudspeaker can be integrated into the housing of the device for trimming hair and beard, with the loudspeaker producing a sound in the situation mentioned above. In an additional alternative, the hair and beard trimming device may comprise a vibrator that vibrates in the situation mentioned above.
[026] According to an additional modality, the user interface is additionally configured to receive, from the user, a second memory input indicative of a second comb position and to send a second memory signal to the control unit in response upon receipt of the second memory input, the user interface being configured to receive a second recovery input from the user indicative of the second comb position and to send a second recovery signal to the control unit) in response to receiving the second recovery input, the control unit is configured to store the position information related to the second comb position on the memory unit in response to receiving the second memory signal, and the control unit is configured to retrieve position information related to the second comb position of the memory unit in response to receiving the second signal l recovery and to control the drive unit to move the attachable comb to the second position of the comb according to the position information related to the second position of the comb.
[027] In other words, the device for trimming hair and beard according to this modality makes it possible to store two definitions of hair and beard length in the memory unit. It should be understood that the hair and beard trimming device can, of course, also store more than two hair and beard length settings. According to a preferred embodiment, the memory unit comprises three or more memory locations.
[028] According to an additional modality, the user interface comprises (i) a screen and (ii) a first button or first input field to receive, from the user, the first memory entry, the second memory entry, the first recovery entry as well as the second recovery entry, the user interface being configured to show a selection menu on the screen if the first button or first entry field is activated for a first predetermined period of time, the selection menu allows the user to select whether to send the first or second memory signal to the control unit, and the user interface is configured to send the first recovery signal to the control unit if the first button or first input field is activated once for a second predetermined period of time, and that the user interface is configured to send the second recovery signal to the control unit s and the first button or first input field is activated twice for the second predetermined time period, the second predetermined time period being shorter than the first predetermined time period.
[029] This mode allows the memory function to be controlled only by means of a button or input field, even if two or more definitions of hair and beard length can be stored in the memory unit and retrieved from the memory unit. memory. The handling of the device is, therefore, still kept as simple as possible for the user. To store a definition of haircut and beard length, the user can, for example, keep the first button or first input field pressed for a second or longer (first predetermined period of time). The screen will then show the selection menu that graphically shows the user various options of memory locations where the desired haircut length and beard / comb position setting can be stored. The user can then select a memory location and confirm the selection, for example, by pressing the first button or the first input field again.
[030] If the user wishes to retrieve one of the stored haircut and beard length settings from memory, the user must activate the first button or first input field by means of a simple click or, for example, by pressing said button / input field for less than a 1 second (second predetermined period of time). After pressing the first button or first input field a first time, the attachment comb will move to the first comb position stored in the memory unit. If the first button or input field is then pressed a second time, the attachable comb will move to the next comb position stored in the memory unit, etc.
[031] According to an additional modality, the user interface comprises (i) a screen and (ii) a haircut and beard length controller to receive a haircut and beard length entry from the user. indicative of a desired comb position, the control unit being configured to move the attachable comb to the desired comb position in response to the entry of haircut and beard length.
[032] In other words, the attachable comb can not only be moved automatically by retrieving a pre-stored comb position from the memory unit, but the user can also “manually” control the drive unit to move the comb Attachable to a desired position. The drive unit can be configured to move the attachable comb continuously or gradually, for example, in 1 mm steps. The haircut and beard length controller can be achieved in many ways. It may comprise a sliding bar or a rotating wheel. In such cases, the attachable comb will be forced to move if the slider is moved up or down, or if the rotating wheel is turned left or right, respectively. The hair and beard length controller can alternatively comprise two buttons, a button to increase the distance between the attachable comb and the cutting set, that is, to increase the length of the hair and beard cut, and one button to decrease the distance between the attachment comb and the cutting set, that is, to decrease the length of the hair and beard cut.
[033] According to an additional modality, the device for trimming hair and beard comprises a first and a second attachable comb that has different sizes and / or shapes, the device for trimming hair and beard additionally comprising a unit of comb recognition which is configured to identify whether the first or second attachable comb is attached to the housing, the recognition unit being additionally configured to change settings of the control unit, memory unit and / or user interface depending on identification of the first or second attachable comb.
[034] In other words, the system in this mode automatically recognizes which type of attachable comb is attached to the housing of the device for trimming hair and beard. The housing can, for example, comprise several keys, the first type of attachable comb being configured to activate the first key and the second type of attachable comb being configured to activate the second key. Alternatively, each attachable comb can comprise an RFID identifier that is automatically identified by the recognition unit.
[035] Recognizing different types of attachable combs has the advantage that the system can automatically adapt to the particular attachable comb. The user interface can be particularly adapted for each type of attachable comb. If the attachable comb in the smallest definition of haircut and beard length already leads to a length of haircut and beard of, for example, 6 mm, the user interface can indicate to the user through the screen that the lowest definition of possible haircut and beard length for this attachable comb is 6 mm. If a smaller attachable comb is attached to the device for hair and beard trimming allowing a minimum hair and beard length of, for example, 3 mm, the screen can indicate to the user that the shortest hair and beard length possible for said attachable comb it is 3 mm. The memory unit can be adapted to the specific attachable comb in a similar way. For example, it may be possible for the user to store three hair and beard length settings in the memory unit for each of the different attachable combs. If the first attachable comb is attached to the device housing for trimming hair and beard, the user can retrieve three different comb positions from the memory unit that he previously saved in the memory unit for that specific attachable comb. If the user then fixes the second attachable comb, the user can retrieve three other comb positions that he has stored in the memory unit for the second attachable comb.
[036] According to a preferred embodiment, the cutting set comprises a mobile cutting blade and a stationary cutting blade, the hair and beard trimming device additionally comprising (i) a motor to drive the cutting blade and (ii) an activation button or activation input field to activate and deactivate the engine. This activation button or activation input field may be different from the first button or input field mentioned above. However, the activation input field can also be a part of a touch screen through which the user controls the memory function as explained above. Brief description of the drawings
[037] These and other aspects of the invention will become evident and will be elucidated with reference to the modality described below. In the following drawings:

[045] Figure 8 shows a schematic block diagram illustrating a procedure for recovering the memory function that is provided by the hair and beard trimming device according to the present invention; Detailed description of the invention
[046] Figures 1 and 2 show an exemplary embodiment of the device for trimming hair and beard according to the present invention in a top view (Figure 1) as well as in a partial exploded view (Figure 2). The hair and beard trimming device is, in this document in its entirety, represented with the reference number 10.
[047] The hair and beard trimming device 10 comprises an attachable comb 12 which is removably attached to the hair and beard trimming device 10. The hair and beard trimming device 10 additionally comprises a housing 14 to which all the other parts are normally integrated and to which the attachment comb 12 can be attached. The housing 14 also serves as a support for a cutting set 16. The cutting set 16 can be releasably fixed at a distal end 18 of the housing 14. The cutting set 16 can also, however, be permanently attached to the end distal 18 of the housing. The housing 14 is, in general, designed as an elongated body that forms a cable 20 at its rear end, that is, the end opposite the distal end 18.
[048] The cutting set 16 comprises a stationary cutting blade 22 and a mobile cutting blade 24. The mobile cutting blade 24 is shown in a known position, mounted in a displaceable manner on an upper surface of the stationary cutting blade 22 The movable cutting blade 24 is resiliently tilted against the stationary cutting blade 22 by means of one or more springs (not shown). These springs exert an elastic force on the mobile cutting blade 24 in order to keep the two cutting blades 22, 24 close to each other.
[049] During the operation, the cutting of hair and beard is performed by the interaction of the stationary cutting blade 22 and the mobile cutting blade 24 that reciprocates over the stationary cutting blade, as is known from other devices for hair trimming and conventional beard.
[050] The stationary cutting blade 22 is generally designed to be thicker than the mobile cutting blade 24. Said stationary cutting blade 22 is also represented as "bulkhead". In order to receive good cutting performance, the movable cutting blade 24 is actively pressed on the upper surface of the bulkhead 22 to receive a so-called tooth pressure. This tooth pressure is, inter alia, ensured by the spring mentioned above, which presses the two cutting blades 22, 24 together.
[051] A drive arrangement that includes a motor (not shown) is configured to drive the mobile cutting blade 24 in an oscillatory manner in relation to the stationary cutting blade 22. The motor is, in general, designed as an electric motor that it is powered by electricity supplied by the mains or powered by a battery.
[052] Depending on the desired cut length of the hair and beard to be obtained, the hair and beard trimming device 10 can be used with or without the attachable comb 12. Specifically when longer hair and beard cuts are desired, the Attachable comb 12 can be attached to the distal end 18 of the housing 14. The attachable comb 12 acts, as it were, as a spacer between the user's skin and the cutting set 16, so that the length of the resulting cut is increased by compared to using the device for trimming hair and beard 10 without the attachable comb 12.
[053] The comb 12 comprises a plurality of comb teeth 26 which are preferably arranged parallel to each other. As can be seen further in Figure 2, the attachable comb 12 comprises a fixing portion which can include, for example, two beams 28a, 28b. These two beams can be inserted into the respective slots 30 which are provided on each side of a mounting portion of the housing 14. The attachment portion of the attachable comb 12 can additionally comprise at least one locking element 32. That locking element 32 can attach the attachable comb 12 when mounted on the housing 14 of the hair and beard trimming device 10.
[054] The attached comb 12 of the presented hair and beard trimming device, unlike most known hair and beard trimming devices of this type, can be moved automatically, that is, in a motorized manner. As schematically shown in Figures 3 and 4, the hair and beard trimming device 10 comprises a user interface 34, a control unit 36, a drive unit 38 and a memory unit 40. User interface 34 can include a screen 42, a haircut and beard length controller 44, a memory button 46 (represented in this document as the first button or first input field) and an activation button 48 (see, for example, Figure 1 ).
[055] The screen 42 can, for example, show the user the actual position of the attachable comb 12, that is, the screen 42 can show the definition of the length of the attachable comb 12 that is currently defined. Screen 42 can also show the user the length definitions that are stored in memory unit 40, as will be elucidated in detail below.
[056] The haircut and beard length controller 44 is configured to receive, from the user, a haircut and beard length entry indicative of a desired comb position, so that the control unit 36 moves, in turn, the attachable comb 12 to the desired comb position by activating the drive unit 38. In the example shown in Figure 1, the entry of hair and beard length can be provided by the user by moving a bar slider that is part of the haircut and beard length controller 44. The upward movement of this slider can, for example, cause the attachable comb 12 to move in the opposite direction to the cutting set 16, so that the definition of the haircut and beard length of the hair and beard trimming device 10 is increased. The movement of this slider bar of the hair and beard length controller 44 downwards, on the other hand, can cause the attachable comb 12 to move in the direction of the cutting set 16, so that the cut length definition of hair and beard of the hair and beard trimming device 10 is diminished. Instead of the sliding bar shown, the beard and hair length controller 44 could also comprise a rotating wheel making it possible to change the position of the comb by rotating said wheel to the left or right, respectively. According to an additional alternative, the hair and beard length controller 44 may comprise two buttons, a button to increase the definition of hair and beard length and a button to decrease the definition of hair cut length and beard.
[057] The activation button 48 enables the activation and deactivation of the motor (not shown) that drives the movable cutting blade 24. The control circuit to control the attachable comb 12 can, therefore, be independent of the control circuit to control the cutting set 16. However, these two control circuits can alternatively be combined into just one common control circuit.
[058] Attachable comb 12 is moved between the different comb positions by means of the drive unit 38. According to the embodiment shown in Figures 3 and 4, the drive unit 38 comprises an actuator 50 or, more particularly, a electromotor. The actuator 50 can be coupled to a gear member 52 which is coupled to a transmission element 54. That transmission element 54 converts a rotary outward movement of the actuator 50 and the gear member 52, if any, into a movement of basically longitudinal positioning of the attachable comb 12. The transmission element 54 can, for example, be designed as a spindle that is coupled to an axle nut 56 that is mounted on a carrier member 58 of the attachable comb 12. However, it must be note that this is just an exemplary way of implementing drive unit 38. Alternatively, drive unit 38 could also comprise another type of linear or rotary motor.
[059] One of the central characteristics of the device for trimming hair and beard 10 according to the present invention is the application of a memory function that allows the user to store his favorite length definitions, that is, his favorite comb positions of the attachment comb 12. In this way, the user can quickly change the position of the attachment comb by selecting a memory entry that it has previously stored. This memory function is explained in detail below:
[060] User interface 34, according to the example shown of the hair and beard trimming device 10, comprises a single memory button 46 (represented in this document as the first button or first input field) that the user can use both to store a desired haircut and beard length setting on memory unit 40, and to retrieve a stored haircut and beard length setting from memory unit 40.
[061] An example procedure for storing a desired haircut and beard length definition in memory unit 40 is schematically shown in Figure 7. In a first step S100, the user must select a desired definition, that is, a position of the desired comb, using the beard and hair length controller 44. As soon as the attachable comb 12 is positioned in the desired comb position, the user can save that comb position in the memory unit 40. The user can check the position of the comb through the screen 42. In the next step S102, the user must press the first button 46 for a longer time, for example, for 1 second or more (first predetermined period of time). Screen 42 will then show a selection menu 60 with different options for memory locations 62a to 62c (step S104, see also Figure 5). Screen 42 can, for example, show several numbers, each of which indicates a different memory location on memory unit 40. Selection menu 60 on screen 42 can, for example, be configured to start flashing. in order to indicate to the user that he can now select a memory location 62a to 62c. The user can then select a memory location in step S106 by clicking on the memory button 46 once or more than once. “Clicking” can, for example, mean pressing the memory button 46 for more than a 1 second (second predetermined period of time). If the user presses the memory button 46 in this situation only once, the first memory bank 62a will be selected; if it presses memory button 46 twice, the second memory bank 62b will be selected; if it presses memory button 46 three times, the third memory bank 62c will be selected etc. In other words, pressing the memory button 46 only once will generate a first memory signal that is sent to the control unit 36. In response to that first memory signal, the control unit 36 will store the selected comb setting / position in the first bank memory 62a from memory unit 40. Pressing memory button 46 twice will generate a second memory signal that is sent to the control unit In response to the second memory signal, control unit 36 will store the setting desired comb position / position in the second memory bank 62b of the memory unit 40. Pressing the memory button 46 three times will generate a third memory signal that is sent to the control unit 36. In response to the third memory signal, the control unit 36 will store the desired comb setting / position in the third memory bank 62c of memory unit 40. The user can confirm the selected memory location 62a to 62c, for example, by pressing the memory button 46 for 1 second or more, again. Control unit 36 can be configured to activate a feedback actuator 62 in response to the desired comb setting / position being stored in memory unit 40 (steps S110 and S112). This feedback actuator 62 can provide the user with feedback that the desired length definition has been successfully stored in memory unit 40. Feedback actuator 62 can generate a vibration alarm, an acoustic signal or an optical signal. In a preferred embodiment, the feedback actuator 62 is part of the screen 42. To guarantee the user that the length definition is stored, the selection menu 60 can, for example, flash once more and then fade.
[062] It will be evident that the recording procedure mentioned above can be designed in the same or similar way in the case where the memory unit 40 comprises only one memory location 62 or more than one memory location. In the event that the memory unit 40 comprises only one memory location 62, steps S104 to S108 can be omitted. Pressing memory button 46 for a longer time (first predetermined period of time, step S102) will then directly generate the first memory signal that is sent to the control unit, the control unit in turn , will save position information related to the selected comb position in memory unit 40. Instead of providing feedback to the user that the desired comb position / definition has been saved in memory unit 40 leaving the selection menu 60 ( in this case, not necessary) flashing, the feedback actuator 62 could, in the case of only one memory location 62, show a specific symbol 64 on screen 42 (see, for example, Figure 6).
[063] It will be evident that, instead of having only one memory button 46, more than one memory button could be provided, for example, a memory button for each location / memory bank 62a to c.
[064] Figure 8 schematically shows the procedure as a user can retrieve a definition / position of the comb that was stored in memory unit 40. The user only needs to press the memory button 46 for less than 1 second (second period of time) predetermined), for example, by clicking on the memory button 46 (S200). Screen 42 will then show the definition stored in the first memory location 62a (step S210). If the definition shown on screen 42 is the definition that the user wants, he can confirm the definition (step S216). Confirming the definition does not, however, necessarily require active feedback from the user. The definition could also, for example, be confirmed if the user does nothing after pressing the memory button 46. If, on the other hand, the user wants to retrieve the comb definition from the second memory location 62b, the user clicks on the memory button 46 again (or directly twice) (step S212). Screen 42 will then show the definition stored in the second memory location 62b (step S214). If the user wishes to retrieve the definition of the third memory location 62c, he must press the memory button 46 three times. In other words, pressing the memory button 46 once for the second predetermined period of time (for example, less than previously) will generate a first recovery signal that is sent to the control unit 36; pressing the memory button 46 twice for the second predetermined period of time will generate a second recovery signal which is sent to the control unit 36; pressing the memory button 46 three times for the second predetermined period of time will generate a third recovery signal that is sent to the control unit 36. However, it should be noted that these different signals are, in the present document, only used as a illustrative measure. In practice, the control unit 36 will recognize the frequency and duration that the memory button 46 is pressed and then react accordingly. If the memory button 46 is pressed once, that is, if the first recovery signal is received, the control unit 36 will control the drive unit 38 to move the attachable comb 12 to the first comb position stored in the first location memory 62a of memory unit 40. If memory button 46 is pressed twice, that is, if the second recovery signal is received, control unit 36 will control drive unit 38 to move attachable comb 12 to the second comb position stored in the second memory location 62b of the memory unit 40. If the memory button 46 is pressed three times, that is, if the third recovery signal is received, the control unit 36 will control the memory unit drive 38 to move the attachable comb 12 to the third comb position stored in the third memory location 62c of the memory unit 40 (S218).
[065] Although not specifically shown in the drawings, the hair and beard trimming device 10 according to the present invention may comprise more than one attachable comb, for example, a first and a second attachable comb, the first being or the second attachable comb can be attached to the housing 14 of the hair and beard trimming device 10. The hair and beard trimming device 10 may in that case comprise a comb recognition unit that can be integrated with or be part of control unit 36. This comb recognition unit can be configured to identify whether the first or second attachable comb is attached to housing 14 and can change the settings of control unit 36, memory unit 40 and / or user interface 34 depending on the identification of the first or second attachable comb. This can provide the possibility of using different memory locations for each of the different attachable combs.
[066] Although the invention has been illustrated and described in detail in the drawings and in the aforementioned description, such illustration and description should be considered illustrative or exemplary, and not restrictive; the invention is not limited to the disclosed modalities. Other variations to the disclosed embodiments can be understood and carried out by those skilled in the art in the practice of the claimed invention according to the appended claims.
[067] In the claims, the expression "that comprises" does not exclude other elements or other stages, and the indefinite article "one" or "one" does not exclude a plurality. A single element or another unit can perform the functions of several items mentioned in the claims.
[068] No reference sign in the claims should be construed as limiting the scope of the invention.
