DETAILED DESCRIPTION

[0036] According to FIG. 1 a view onto a preferred aspect of the present invention is shown. A driving unit 1 with a body can comprise one or more batteries and/or a socket for a cable for loading the device or for supplying power to one or more motors (not shown) contained in the driving unit 1. Onto the driving unit 1 a rear or first head 2 and a front or second head 3 is shown. These heads 2,3 are mounted onto the driving unit 1, preferably in a manner allowing some movement up and down as indicated by the arrows. This movement is biased as to essentially ensure that the heads are in the outermost positions before use. When during use pressure is exerted onto the heads by attaching and slightly pressing the device against a user's skin they can preferably more downwardly in order to better conform to the contours of the user's skin under treatment.

[0037] Moreover a knob is shown on the right hand side and also present on the opposite side in order to allow one or both heads 2,3 to be released from the driving unit 1. Any other arrangement can fulfill the same function.

[0038] According to FIG. 2 an exploded drawing shows the heads 2,3 in a released position. Below are shown elements that are preferably assembled to the driving unit 1. One motor 6,7 is shown for driving each head 2,3. The driving pin extends in this embodiment to the upper side towards the heads 2,3. On top of such driving pins is a polygonal element such as a hexagon 4,5 in order to engage the respective coupling element (not shown) to each head 2,3. A support 8 is also shown for supporting the motors 6,7. In the assembled status the driving rods of the motors 6,7 extend through the support 8 and the hexagons 4,5 are placed on top of them.

[0039] A snap on element or latch 10 is also shown which in this preferred embodiment is provided on a tongue of support 8. Preferably 4 latches are provided, a pair for each head 2,3. Such latches engage respective elements (not shown) provided in the heads 2,3. Such latches can be brought out of engagement by the respective knobs.

[0040] The rotating bodies in heads 2,3 are covered at their ends by the head cover and allow the accessibility of them to the user's skin in use through respectively formed windows.

[0041] FIG. 3 depicts an example of a head 2 from the underside that is directed towards or onto the driving unit (not shown) in use. As already also visible in the previous FIG. 2 the concave shape of the rotating body 17 towards the user in use is apparent.

[0042] Moreover, a coupling 13 with a coupling element 13a can be seen which usually engages the driving pin of the motor (not shown) in use. As mentioned this connection between the coupling element 13a and the driving pin allows for some movement of the driving pins within the coupling elements 13a in uses, particularly for compensating the displacement of the respective head in use.

[0043] At the bottom of the coupling element 13a gear teeth are visible forming a gear. This intermeshes with another gear 14 for preferably reducing the turning speed or respectively enhancing the torque of the respective rotating body 17. The gear 14 is further connected with gears (not shown) driving the rotating body 17.

[0044] Moreover, a pair of springs 15 is shown biasing the head 2 against the support as shown in the previous figure. They cause the biasing and the possibility of displacement of the head during use when sufficiently pressed to the skin of a user.

[0045] A window 16 is also apparent in FIG. 3 for allowing the latches (not shown) provided in the support to engage and to releasably hold the head 2 in the outermost position when no displacement takes place. This is usually the case when the head 2 is attached to the driving unit but when the device is not in use or no pressure is exerted onto the head 2.

[0046] FIG. 4 shows in the upper part a top view onto the two heads with the exposed rotating bodies being visible through the windows of the head's casing. The hair of a user preferably is clamped or grasped and pulled into the gap between the two rotating bodies and thereby epilated or removed.

[0047] Further below is shown a sectional view A-A onto the support, one motor 6 and one head 2. The exposed part of the rotating body 17 is shown in its concave configuration from the side in order to better conform to the skin of a user. The front hexagon 5 is shown in the engagement with the coupling 13 and the gear formed therein. Also the dimensions and tolerances allowing the displacement of the head 2 downwardly or towards the driving unit (not shown) are apparent. This is even better shown in Detail C showing hexagon 6 engaging coupling 13.

[0048] During the activation of the motor 6 the coupling 13 is turned which drives the further gear 14 that itself drives another gear within the head 2 for driving or making the rotating body 17 turn.

[0049] In section A-A the functioning of the head 2 and its biasing arrangement onto the support or driving unit by springs 15 is already apparent. Further the engagement of the latch 10 into the window 16 is shown. This part is shown enlarged in Detail B showing the displacement of the head towards the driving unit (not shown) or the support by the distance of latch 10 and the lowermost edge of window 16.

[0050] In FIG. 5, FIG. 6 and FIG. 7 a further aspect according to the present invention is shown. In these figures the epilator can be separated into two halves while preferably still allowing the epilator to be operated by a user from one side or by one knob or button.

[0051] In more detail shows FIG. 5 the two halves of epilator 19 are attached to each other. The heads 21,21A are provided similarly as described before. However, they are either fixedly attached to corresponding driving units 20,20A as shown or are attachable to separate driving units in a releasable manner. In the embodiment shown a switch 22 is provided on one side of one driving unit 20 of the driving units. A release button 23 is preferably provided on the same side as the switch 22.

[0052] FIG. 6 exemplifies the separation of an epilator according to FIG. 5. It specifically allows a view onto one example of connecting means 28. Slide tracks 28 are shown at the inner side of driving unit 20A engaging corresponding slide tracks (not shown) at the inner side of driving unit 20. In the embodiment shown the drive units 20 and 20A are attached at the inner sides. Electric contacts 27 are also visible which allow a control of both driving units 20,20A by one switch 25. The release button 26 allows the release of both drive units 20,20A upon its activation.

[0053] FIG. 6 and FIG. 7 together show one example of the arrangement of both halves of the epilator or of both driving units 20,20A together. Connecting projections 29 arranged at driving unit 20 can be inserted into respective windows or recesses in the driving unit 20A formed into the sliding tracks 28. To be more precise, the upper pair of projections can be inserted into the upper pair of recesses on the opposing side and the lower pair of projections 29 is adapted to be inserted into the lower pair of recesses. The driving units are then moved along their inner surfaces until the projections are positioned in the undercut parts of the sliding tracks 28. Preferably a release button projection 30 arranged in drive unit 20 engages a respective corresponding element (not shown) arranged in drive unit 20A. The two drive units 20,20A snap then into a position where they are aligned with each other. Upon activation of release button 26 on the outer surface of drive unit 20 shown in FIG. 6 the release button projection 30 connected therewith is retracted and allows a repositioning of both driving units 20,20A so that they can be slid again into the position to be taken apart.

[0054] FIGS. 6 and 7 also show electric contacts 27 at drive unit 20A and corresponding contacts 31 at drive unit 20. They get in touch with each other in the locked position of both drive units 20,20A so that the epilator can be activated by one switch 25 that corresponds to switch 22 shown in FIG. 5.

[0055] The embodiments shown and described are intended to exemplify the nature of the present invention and do not limit the scope or gist of the present invention.
