A housing 1 that accommodates dynamic elements and a housing 1 that is removably arranged in this housing 1. Tighten the hair removal device consisting of the hair removal head 100 with element 5.6 open. It is shown in cross-section in . In the housing 110 of the hair removal head 100, there are many For tightening, a rotary cylinder 7 is provided, which is formed by elements 5, 6; This rotating cylinder 7 is rotated by a transmission gear 102 of a gear device 8 . Tighten Elements 5 and 6 are connected to actuating elements 9 and 10 passing through the rotating cylinder 7. There is. These actuating elements 9, 10 are supported rotatably on a shaft 141. movable on element 103 parallel to the central axis x-x against the pressure of spring 44 It is located in The actuating elements 9, 10 and the spring 44 biasing them together are It forms an actuating element unit. The second actuating element unit is connected to the first actuating element two. diametrically opposed to the knit and supported horizontally movably on the support element 103. It is. A transmission gear 102 that rotates the rotary cylinder 7 is driven by a support element 103 connected.

Rotatably and movably supported on a shaft 141 on both end surfaces of the rotating cylinder 7. control elements 45 and at least one push actuating each control element 45; A pressure element 47 is provided. In the embodiment shown in FIG. Each pressing element 47 located on a plane extending parallel to x-x is provided with a separate diametrically opposed pressure elements 47 are attached. The pressing element 47 is a truncated cone shaped and each rotatably supported on a bearing pin 59 . diametrically The conical tip of the suppressing element 47, which is disposed opposite to the It converges at point 0. Therefore, the circumferential surface of the pressing element 47 of the control element 45 is rotated. The linear velocities of all contact points on the control surface 46 are of the same magnitude. Control element 4 A structural embodiment of No. 5 is shown in FIG. Tightening is connected to elements 5 and 6 The two actuating elements 9, 10 each enter the open state and the open state once in the course of one revolution. The corrugated shape of the annular control surface has two ridges to ensure that the It has a starting portion 461 and two depressions 462.

A shaft 141 is supported within the housing 110 of the epilation head 100 and has a bearing pin. Two holding elements 70, 71 are provided, to which 59 are fixed. of shaft 141 A spring 49 and a tightening element 50 are provided at both ends. These allow the spring The mutual spacing of the holding elements 70, 71, which are biased at 49, and therefore of the suppressing element 47 The mutual spacing can be adjusted by applying pressure to the spring 49 with the tightening element 50 . For this purpose, at least one holding element 70.71 is attached to the housing of the hair removal head 100. It must be movably supported within housing 110. The spring 49 is especially a disc spring. As such, the tightening element 50 is adjustable on the threads provided at both ends of the shaft 141. It is formed as a nut that is screwed into the

The adjustment of the mutual spacing of the pressure elements 47 via the respective holding elements 70, 71 is controlled. It is transmitted via the element 45 to the actuating element 9-10 passing through the rotary cylinder 7, and thus can be moved relative to each other against the pressure of the spring 44 of the actuating element unit, and no tightening is required. The spacing between the actuating elements 9 and 10 supporting the elements 5 and 6 is varied.

The clamping element 5 arranged on the actuating element 9.10 and cooperating in pairs via these ．． The distance 6 takes determines the force of the tightening that occurs. This spacing and therefore tightening The tightening force exerted on element 5.6 is caused by rotation of at least one nut 50. can be modified, in which case the tightening is performed with a very small force with the participation of the elastic deformation of the disk spring 49. Kana adjustment is guaranteed. The fastening attached on the actuating element 9.10 is element 5, The reduction in the spacing for the pressure elements 47 of 6 in the embodiment shown in FIG. , the tightening of the elements 5.6 attached to each other results in an increase in force and the distance between them An increase in tightening results in a decrease in force.

The hair removal device in FIGS. 5 and 5a has two parts passing through the rotating cylinder 7. The operating element unit has two operating element units, and one of the operating element units is as follows. This will be explained in detail below. The actuating element 9.10 is connected to the support element 103, which is square in design. It is slidably arranged on the sliding surface 104 parallel to the central axis x-x of the shaft 141. ing. Actuating elements 9.10 arranged next to each other or interlaced with each other are Tightening is carried out by means of slides in which the elements 5, 6 are mounted alternately or swingably supported. It is equipped with

In one clamping element 5 forms a row of elements, the element 5 is connected to the actuating rod 9, and in the other The clamping elements 6 forming a row of clamping elements are connected to the actuating rod 10. operation The rods 9.10 can be moved relative to each other against the pressure of the spring 44, so that the restraining element 47 via the control element 45, the tightening of element 5 is caused by the element row The relative slippage of the element rows is as shown in Figure 5a. The tightening causes the element 5 and the tightening element 6 to be pressed together. Tightening is done after the process In the process of rotating the rotating cylinder 7 more, the tightening element 5.6 is As shown in FIG. 5, the tightening is caused by the spring 44 in the state A push and release of 0 places it in the open position.

5 and 5a, each rotation of the rotating cylinder 7 tightens the element 5, In order to obtain the process of tightening twice in step 6, tightening is an element as described above. A hair removal device is shown with two actuating element units with 5°6. to this On the other hand, for the rotating cylinder 7, the only tightening per revolution is the only action to perform the process. It is possible to have only a dynamic element unit, and multiple tightening requires two or more to perform the process. It may also be provided with an actuating element unit.

In that case, the stroke required for the movement of the relatively movable actuating elements 9, 10 is controlled A ridge 461 and a recess 462 molded into the control cam 46 of element 45 (FIG. (see FIGS. 1a and 4).
