A device for removing body hair is already known (EP 0 328 426 A2), which consists of a housing with a removable Epilation head exists. The housing is also used for recording one driven by a motor, mounted on a shaft Rotary cylinder with several actuating elements passing through the rotary cylinder for actuating the clamping elements coupled to it. The actuators are each end of one rotatably mounted on a bracket arranged in the epilation head Roll applied once per revolution and are against the pressure of a common spring can be moved back and forth in opposite directions. The oppositely adjustable actuators can be adjusted via a spring Always in neutral position after a work process brought, with the clamping elements back in their starting position can be reset. So trained Epilation devices always work in the same direction of rotation and are designed so that they only move in one direction epilating skin surface can be passed to the hair too capture and remove. However, in order to have a perfect epilation effect To be able to achieve the epilation device with his Front always moved against the direction of growth of the body hair will. However, the direction of growth changes on the one to be epilated Skin surface, so the epilation device should be turned be so that the body hair can be grasped in time and thus completely. By moving the device in the direction of growth of the body hair, these become late or imperfectly grasped and depressed so that they are only partially be removed. The invention seeks to remedy this.

The invention has for its object the removal of body hair by means of a To improve device of the type mentioned.

This object is achieved according to the invention by an epilation device with the features of Claim 1 solved. Due to the advantageous design and arrangement of the various Actuators or pressure elements or control elements for direct or indirect Adjustment of the clamping elements ensures that the body hair from the Clamping elements are always correctly detected and fed to the clamping area, no matter how the implement is used or in which direction it goes over the skin is moved. For this it is essential that when the direction of rotation of the rotary cylinder changes the position of the contact point between the pressure element and the actuating element is changeable. The direction of rotation of the rotating cylinder of the epilation device is through Switching the motor to the direction of movement of the epilation device during work adaptable or reversible. For example, if the epilation device is used by one in the other hand and thereby in the direction of growth of the body hair attached to the skin surface, the direction of rotation can be switched by switching the motor of the rotary cylinder change immediately and thereby achieve that the clamping elements now against the direction of hair growth over the surface of the skin. To this In this way, the body hair can easily be fed to the clamping elements and thereby be captured by these flawlessly.

Furthermore, it has proven to be advantageous that the position of an investment site between the pressure element and the actuating element can be changed in one plane, which runs substantially perpendicular to the axis of rotation of the rotary cylinder and that at the Place an adjustment of at least one clamping element in the direction of a adjacent clamping element begins.

Fig. 5 shows a second embodiment of the device for removal of body hair that easily moves in both directions each against the direction of growth of the body hair is to be used.

The epilation device 1 consists of the rotary cylinder 4 and an im Epilation head 3 rotatably mounted component 261 with the fixed arranged clamping elements 42 and the movable clamping elements 43. (Further details can be found in the patent application FR A 91 10 965).

The movable clamping elements are with the clamping elements 42 of the component 261 penetrating actuator 109 coupled and pivotally mounted in bearing points provided on component 261. For holding and guiding the actuating element 109 within the rotary cylinder 4, the latter are the clamping elements 42 and 43 passing through holding elements 601. On that The end facing the pressure element 147 is the actuating element 109 and the holding elements 601 within the opening of a guide element 602 stored and by means of an actuating element 109, the holding elements 601 and a guide element 602 passing through Pin 603 connected to a unit. The one End face 603 on the pressure element 147 adjacent guide element 602 is in an end plate 605 of the rotatably mounted component 261 mounted horizontally movable. That facing away from the pressure element 147 The end of the actuator 109 is in an end plate 606 of the component 261 provided opening 607 against the pressure the spring 6 mounted horizontally. To in the course of a Rotation of the rotary cylinder 4, the clamping elements 42 and 43 twice to use, the second actuator is 110 um 180 ° offset from the previously described actuating element 109 arranged in the component 261 and formed analogously. Since this second actuating element 110 is not in contact with pressure element 147, the spring 6 is in the relaxed state. Therefore take the movable clamping element 43 to the clamping elements 42 one predetermined distance, which is used to capture the to be extracted Hair is required. The component 261 of the rotary cylinder 4 is with a left shaft end 610 in a bearing block 608 'and with a right shaft end 610 is rotatably supported in the bearing bush 18. A right bearing block 608 is on the bearing bush 18 pivoted.

Component 261 is driven by drive wheel 8 and one in housing 3 located drive means driven in rotation. The Pressure element 147 is on an appropriately trained eccentric 10 rotatably mounted. The one provided with an adjustment lever 100 Eccentric 10 is rotatably mounted on a rod 222 which is received in the bearing block 608. By moving the lever 100, the eccentric 10 transmits its eccentricity via the pressure element 147 on the actuating element 109 or 110 and causes a corresponding change in the clamping effect interacting Clamping elements 42 and 43.

FIG. 6 shows an epilation device similar to that in FIG. 7 but with a clamping element 150. (Further details follow from patent application FR A 91 106 96).

In the housing 2 there are electrical and mechanical drive elements, such as the motor 103, a transmission 208 and a switch 104 are provided. Furthermore, the epilation device 1 according to FIG. 6 and 7 on the rotary cylinder 4 clamping elements 105 and 106. The rotary cylinder 4 consists of those which are movable relative to one another Actuators 109, 110, which with the clamping elements 105, 106 are coupled and bring them into their clamping position.

A rotary shaft 114 passing through the actuator 109 is firmly connected to the actuator 109 and in the housing 2 bearings 115, 116 provided rotatably. Of the The rotation shaft 114 is driven by the motor 103.

6 is designed as a bow spring Spring 149 shown. The one facing away from the rotary cylinder Side of the bow spring 149 is with the two bow legs in contact with the stops 152 and 180.

Between the actuating element 110 and the pressure element 147, in which is a ball 148 rolling, is a control 145 provided with a control cam 146 (Figure 8). The control curve 146 is, for example, wave-shaped and points at least one recess 162 and an elevation 161.

The setting of the clamping force (Figure 6) of the pairs interacting Clamping elements 105 and 106 take place after assembly of the epilation device by adjusting the clamping element 150 over a clamping lever 151. The clamping force of the clamping elements 105 and 106 depends on the spring force of the bow spring 149.

FIG. 7 shows a section through the housing 2 of the epilation device 1 without clamping element (fourth embodiment) in which electrical and mechanical drive elements such as a memory cell, the motor 103, the electrical connection of the memory cell switch producing or interrupting motor 103, the transmission 208 and the clamping elements 105 and 106 having rotating cylinders 4 are arranged. (More details result from the patent application FR A 91 106 97).

The rotary cylinder 4 consists of those which can be moved relative to one another Actuators 109 and 110 with the actuators coupled clamping elements 105 and 106 and a cylindrical, several comb teeth having comb teeth.

The rotary shaft 114 passing through the actuator 109 is firmly connected to the actuator 109 and in the two bearing points 115 and 116 provided in the housing 2 are rotatable stored.

In this way, all movable clamping elements 105 of the Rotary cylinder 4 with the actuator 110 by the engagement in, not shown in the drawing, coupled to grooves and others via arms in the grooves of the actuator 109 pivoted.

Since the mode of operation and the construction is similar to that in FIG. 6, only those parts that have not yet been described are discussed below, which in detail from patent application P 91 106 97 are removed.

As can be seen from Figure 7, is between one on the actuator 109 arranged stop 142 and one on the actuating element 110 molded stop 143 a spring 144 is provided, the the relatively movable actuators 109, 110 and consequently the clamping elements 105, 106 of a clamped position moved to an open position.

The control element 145 is displaceable on the rotation shaft 114 stored and with a parallel to the Rotaionswelle 114 Provided backdrop 153, in the one on the actuator 109th arranged driver element 154 for the purpose of transmitting the rotational movement intervenes. The length of the backdrop 153 and in this engaging driver element 154 is one on the other matched that the slidably mounted on the rotary shaft 114 Control element 145 that specified by the control curve 146 Can perform actuation stroke.

The gear 208 consisting of several gears is between the bearings 115 and 116 arranged and with the rotation shaft 114 driven coupled.

This is on the end face facing away from the actuating element 110 Control element 145 is provided with the control cam 146, which is in connection with the pressure element 147 arranged in the housing 2 the control element 145 against the pressure of the spring 144 the actuating element 110 moves.

Are the clamping elements 105 and 106 of the epilation device in the open Position, then the pressure element 147 is in the depression provided in the control cam 146 of the control element 145 162. In the course of a rotation of the control cam 146 by 180 ° the intended increase 161 in this comes to the plant Pressure element 147, causing a displacement of the actuating element 110 with the clamping blades 105 against the pressure of the spring 144 is effected and the clamping lamellae 105 for contact with the the actuating elements 109 coupled clamping lamella 106 as shown in Figure 6.

The pressure element 147 is by means of a bore on one in the housing 2 fixed bearing bolts 159 (Figure 7) rotatably mounted and designed as a truncated cone, with one to the central axis x-x of the rotating cylinder 4 aligned cone tip.

The pressure element 147 lies with its outer surface on the parallel to this lateral surface extending control surface 146 of the control element 145 rotatably mounted on the rotary shaft 114 on. The tip of the cone of the pressure element designed as a truncated cone 147 preferably ends at point 0 on the central axis x-x. As a result, the linear velocities are all points of contact the rolling on the outer surface of the pressure element 147 Control surface 146 of the control element 145 is the same size.

Details of an embodiment of the control element 145 are further shown in Figure 8. In adaptation to the lateral surface of the pressure element 147 designed as a truncated cone from the inside outwardly sloping, circular control surface 146 is provided with a wave-like shape, which means at least one increase in the respective application 161 and a recess 162 are formed. In the illustrated The control surface 146 of the control element is an exemplary embodiment 145 provided with an elevation 161 and a recess 162. Each according to the embodiment of the epilation device, several can also Increases and depressions are provided alternately below be.

In the device types according to FIGS. 6 and 7, the axis of rotation runs parallel to the main axis of the device and in work also parallel to the skin surface. The way of working is at both devices the same.

The body hair can, as explained below, only optimally be detected if the device is against the direction of growth of the body hair is moved over the skin.

To provide a device that works in both directions 15 to 17 can be used effectively, it is particularly advantageous that the direction of rotation of the device and the setting angle α of the bracket 22, a bracket 690 (figures 9 to 12) or the control element 145 (FIGS. 13, 14) each can be changed accordingly after handling.

There are various ways of making the device 1 more advantageous Way to adjust to different conditions. To the one is to change the direction of rotation of the device and at the same time the setting angle α of the driver 154 with respect to the axis x-y to adapt to the changed condition.

Based on the schematic representation in Figures 15 to 17 is shown how the individual clamping elements take effect.

In Figure 15, the housing 2 of the device 1 is schematically in a vertical position shown so that the axis x-y with the contact surface the skin forms a right angle, an axis of rotation 108 of the rotating cylinder 4 runs parallel to the skin surface and the area marked A is the front of the Device represents the direction of the hair to be removed shows. Furthermore, the axis of rotation runs in this embodiment 108 perpendicular to the main axis x-y of device 1 (cf. the exemplary embodiments according to FIGS. 15, 17).

In the device type according to FIG. 15 or 4a, b, the device is countered the direction of hair growth moves over the skin by hand. 15 and 4a, b, the rotary cylinder 4 advantageously rotates in direction A according to arrow R.

The device 1 is with its epilation head 3 at point b on the Skin surface put on (Figure 15). The main axis forms x-y in this embodiment with the skin surface a right one Angle. The rotary cylinder 4 rotates according to arrow R with reference to the display in a clockwise direction. Before point a the clamping elements 42, 43 or 105, 106 are still in an open position, since the pressure elements 147 have not yet taken effect are.

The respective contact point a according to FIG. 15 becomes dependent from the direction of rotation of the rotary cylinder 4 by engaging the driver 154 on one of the stops 611 or 612 and by contact the respective increase 161 of the control curve of the control element 145 determined on the pressure element 147.

The point a is also the contact point between the pressure element 147 and the actuating element 109 or 110. Comes when the direction of rotation changes of the rotary cylinder 4, the actuating element 109 or 110 against the pressure element 147, then an adjustment begins at least one actuating element 109 in the direction of adjacent actuating element 110 or both are against each other moved so that by further turning the rotary cylinder 4 the clamping elements 42, 43, 105, 106 move into their closed position.

The clamping elements 42, 43 and 105, 106 close from point a gradually towards point b. The point b corresponds to the point of contact of the clamping element with the skin surface.

The clamping elements 42, 43, 105, 106 remain between the point b and c closed and only gradually open again between the two points c and d. This ensures that to remove the body hair creates a stroke that is sufficient that the body hairs are grasped and removed properly. Out of this it also follows that the sole change in the direction of rotation Rotary cylinder 4 is not sufficient to optimally remove the body hair. This work cycle is repeated at least once per cylinder rotation.

It can also be seen in FIG. 15 that no body hair is detected are changed if only the direction of rotation of the rotary cylinder 4 and the epilation device 1 is moved to the right. Then starts the closing process of the clamping elements already at point d and is closed at c. Therefore, from the clamping elements no hair is caught and therefore not pinched.

In Figure 16 are the individual positions of the actuators 109, 110 shown between points a and d. Thereby 1 between x-y and P the path of the actuating rods 109, 110, when the rotary cylinder 4 passes through the angles α. The dimension e gives the working width of the actuating rods 109, 110 again. If the Actuating rods 109, 110 in position 2a with the pressure elements 147 come into contact are the clamping elements 105, 106 still open (see Figure 15, point a). From position 2 (a) 2 (b), the pressure elements 147 move the actuators 109, 110 by the amount X and combine them in point b. The clamping elements remain closed in position 2 (b) until until the working width e of the actuating elements 109, 110 has passed the contact point P on the pressure elements 147. After that the opening phase of the clamping elements begins between 2 (c) and 2 (d). The rest of the process is as described.

From this scheme it follows that the travel 2 (a), 2 (d) and the travel 2 (b), 2 (c) symmetrical with respect to the main axis x-y run.

To achieve that when reversing the direction of rotation of the rotary cylinder 4 the clamping elements 42, 43 and 105, 106 in the same way, as shown in Figure 15 (the closing point of Point b according to FIG. 15 corresponds to the closing point c 'in FIG 17), close at the right time, the position of the pressure element 147 by the size 2α from the position according to FIG. 11 in the position according to Figure 12 pivoted beyond the axis x-y.

For this purpose, the individual pressure elements 147 according to FIGS. 9 to 12 on the pivoting device or bracket 690, the can be designed as a bracket 22 or as a bearing block 608, between the two fixed, provided on the epilation head 3 Stops 611, 612 is adjustable. This swivel Device or holder 690 is for all epilation devices that work according to this principle (Figures 1, 3, 5, 4a, b) and in particular described in this application can be used.

The following is the way of changing the working direction explained for the arrangement of the first device type. In Figure 3 is a storage and in Figures 11, 12 the adjustment of the bracket shown between the stops.

As can be seen from FIGS. 11, 12 and comparatively from FIG. 3, are the legs 21 of the bracket 22 in the slot openings 20 of the journal 25 is added, which are part of the axis 19. The bearing pins 25 are in the bores 693 of the bearing bush 17, 18 of the epilation head 3 is added such that the bracket 22nd with the pressure element 147 between the spaced apart Can pivot stops 611, 612.

By pivoting the bracket 22 between the stops 611, 612 ensures that the bracket 22 with the pressure elements 147 always in the desired and therefore most favorable position (see Figures 11, 12) is pivoted.

In the exemplary embodiment according to FIG. 3, when the direction of rotation changes the Mototrs the bracket 22 after the actuation element 110 against the pressure element 147 by means of the rotational movement of the actuating element 110 is pivoted out of the position according to FIG. As shown in Figure 12, the side Limitations of the slot opening 20 (see FIG. 12) also as stops 691, 691 'act.

In Figure 11, the pressure element 147 has taken the position in which the rotary cylinder 4 rotates in the direction of the arrow R (cf. also Figure 15) and the contact point between the pressure element 147 and actuating element 109 one identified by the angle α Has assumed the angular position. The rotary cylinder 4 with the associated bracket 22 takes the working position according to this Figure 11 a so that the axis x-y with the contact surface of the Skin forms an approximately right angle and the axis of rotation 108 of the rotary cylinder 4 runs parallel to the skin surface and the side marked with A (left figure 15) the front represents the device against the direction of growth of the to be removed Shows hair. Further runs in this embodiment the axis of rotation 108 perpendicular to the main axis of the device 1 (cf. the exemplary embodiments according to FIGS. 1 and 3 and the individual positions of the two device types according to figures 11, 12). The hair is now, as already described in detail, starting at a and between during the lifting process b and c removed.

This is advantageously achieved by making changes the direction of growth of the hair the change of direction of the Revolving cylinder 4 is changed and thereby an automatic adjustment of the bracket 22 from the position shown in Figure 11 in the optimal working position shown in FIG. 12, when the device is moved to the left over the skin.

Because the clamping elements between point b and c remain closed and will only open between the two points c and d when lifting between b and c ensures that the body hair clamped properly and then removed between a and b will.

According to the embodiment shown in Figure 5, the device works similar way as the device of Figure 3. For this purpose, the Eccentric 10 receiving pressure element 147 arranged on rod 222, which is accommodated in the bearing block 608, which is on the bearing bush 18 between a position according to FIG. 9 and one Position is pivotally mounted according to Figure 10, so that the Bearing block 608 against the left stop 611 or the right one Stop 612 is present. The pivoting of the Bearing block 608 by engaging the actuator 109 (as in the bracket 22) against the pressure element 147 when the direction of rotation the engine is changed.

This makes the effective investment point in a simple manner (see P in Figures 9 to 12) between pressure element 147 and Actuator 109, 110, at least one adjustment a clamping element 109 in the direction of the adjacent clamping element 110 with respect to the fixed major axis x-y of the housing 2 begins, relocated. The through the pedestal 608 and the Point P running center line forms with the axis x-y that can also be referred to as the transverse center plane of the device 1, an angle α. By changing the direction of rotation, the bearing block 608 adjusted between + α and - α and thus also the relative Contact point P between the pressure element 147 and the actuating element 109. In principle, it is important that the investment site P is changed in its angular position with respect to the axis x-y.

To avoid repetitions, only the How the adjustment works with one of the actuators 109 firmly connected driver 154 of the third and fourth Embodiment according to Figures 6, 7, 13, 14 explained in more detail.

In the case of epilation devices in which, according to FIGS. 6, 7, the pressure element 147 and the corresponding control element 145 interact, becomes the control element rotatably supported on the rotary shaft 114 145 opposite the driver 154 between the stops 611, 612 adjusted.

For this purpose, the control element 145 is provided with a cutout 692, which is limited by the two stops 611, 612. At a change in the direction of rotation of the rotary cylinder 4 becomes the control element 145 adjusted in the angular range α (see FIGS. 13 and 14), the stops 611 and 612 meet alternately the driver arranged in a rotationally fixed manner on the rotary shaft 114 154 to the facility.

As already described, the device according to FIGS. 6, 7 contains the Clamping elements 105, 106, which are adjustable relative to one another, one clamping element 105 is stationary and the other clamping element 106 is movable.

According to Figures 6, 7 and 13, the rotary cylinder 4 rotates in Direction of rotation according to arrow R. Here, the driver 154, the part of the actuating element 109 is rotated by the rotary shaft 114 and thereby rotates the control element 145, whereby the Carrier 154 supports against the stop 611.

In the position shown in FIG. 13 there is a protruding one Part or the control surface or cam 146 of the Control element 145 on an axis labeled 614 with the x-y Ball 148. Be in this position (see contact point P) the clamping elements 105, 106 already in the closed state - point b - and remain in this position in the angular range α, then the clamping elements 105, 106 are moved apart again.

If the direction of rotation is changed by the Arrow R is indicated, then the ball 148 brakes the control element 145 and the driver 154 comes against the stop 612 to the facility. Now the same, already described can Repeat the clamping and opening process. (See also the in Principle same function regarding the examples according to the figures 9 and 11).

The clamping elements 42, 43 and 105, 106 are used for all device types always pressed against each other when at least one actuating element 109, 110 either on the pressure element 147 or on an increase 161 in the control surface 146 of the control element 145 is moved past (see plant P), so that then according to Figures 6, 7, the pressure element 147 on the control element 145 the actuating element 110 or according to FIGS. 2, 3, 5, 6 Pressure elements 147 directly on the actuating elements 109, 110 can act.

It is possible that when the direction of rotation of the motor or other drive elements (by means of a not shown in the drawing Embodiment) automatically changes the position of the Pressure elements 147 and the actuating elements 109, 110 with reference is brought about to the axis x-y, so that the detection of the body hair always done in time using the clamping elements.

The bracket 22 can also have a not shown in the drawing, manually or via an encoder that can be influenced, electrical Control device automatically depending on a disturbance variable can be adjusted to the desired position. For example it is possible that the adjustment of the bracket 22 automatically when the direction of rotation of the drive motor 3 changes, the for this purpose via a pulse generator, not shown in the drawing can be connected to an encoder. For this it is advantageous that the start of the movement of a clamping element 42, 43, 105, 106 in the direction of that interacting with and adjacent to it Clamping element is controllable.
