2. Description of the Prior Art Epilation devices of the type mentioned at the outset are known from French patent application DE 2656994. The rotary cylinder of the epilator consists of groups of three clamping lamellas arranged on a shaft driven by an electric motor. An elastomer disc is provided between each group of fastening thin plates, and the fastening thin plates that are located on both sides and are swingably supported by this elastomer disc are fixed on the shaft between the two swing thin fastening plates. The supports, which are arranged in the same position, ie held in the closed position. Longitudinal axis xx 'of the axis of the rotating cylinder
Parallel to, outside the circumference of the rotary cylinder, an actuating element with a number of cutout openings is provided on the epilation device,
In that case, both clamping lamellas of each group pass through one of the notch openings in order to cause an opening movement with respect to the support between both of the movable clamping elements over the predetermined width of the notch opening. Is extended. In order to ensure the open movement of the swingable clamping plate, the support is short on the side opposite the clamping range. The main drawback of this control of the clamping lamellas is that the pivotally supported clamping lamellas of the clamping lamella group only come into contact with the support arranged between them during the rotation process of the rotary cylinder. .

[0003]

SUMMARY OF THE INVENTION The object of the present invention is to improve the hair removal action of a hair removal device of the type mentioned at the outset.

[0004]

According to the invention, the object is to provide a depilation device of the type mentioned at the outset, in which a support is provided between the relatively movable clamping elements, each movable clamping element of the rotating cylinder being provided with a support. This is achieved by cooperating alternately with the supports arranged on both sides during rotation and in each case.

The main advantage of the invention is that in the course of the rotation of the rotary cylinder, each movable clamping element has a clamping synergism with the adjacent support. With this measure, French Patent Application Publication No. 265
Compared to the known device according to 6994, the rotary cylinder is arranged on the respective end face side of the rotary cylinder, provided that the number of fastening elements pivotably and pivotally supported is the same. Except that only the outer end face of the movable tightening element that is being used has no tightening action,
The number of tightening areas that effectively act on the skin surface is doubled. The number W of supports provided according to the invention is given by the following equation for a given number of movable clamping elements.

W = Ke -1 where W is the number of supports and Ke is the number of fastening elements.

Since the tightening process occurs twice by the pressing element acting on the actuating element for each revolution of the rotary cylinder, the number of tightening processes is given by the following equation.

W × 2 = 2 Ke −2 In a preferred embodiment of the invention, the rotary cylinder is rotatably supported on the shaft by means of a bearing part, the movable clamping element being connected to an actuating element passing through the rotary cylinder and pressing. It is proposed that, under the action of the element, the actuating element is arranged, together with the clamping element, on the bearing part so as to be movable relative to the action of at least one spring, and the support is arranged on the bearing part. In particular, one actuating element and one actuating element are arranged diametrically opposite one another on the bearing part so as to be movable relative to each other. In an advantageous embodiment of the invention, the support is arranged at right angles to the shaft and is provided with clamping surfaces on both sides of the shaft. In particular, the clamping surfaces are provided diametrically opposite each other on the support. In an embodiment of the invention, the support consists of a disc with a clamping surface that corresponds to the clamping element.

Furthermore, it is advantageous if a support arranged between the clamping elements is supported on the bearing part so as to be displaceable at least axially. The freely displaceable arrangement of the supports ensures that the support contacts the clamping elements in a satisfactory manner even when the support is not optimally centered on the bearing part. In this way, further tolerances in the production of the tightening element are easily compensated.

In a development of the device according to the invention,
The support provided between the clamping elements has a concentric cutout opening, the cross section of which is preferably rectangular.
It is proposed to be somewhat larger than the total cross-sectional area of the bearing part and of the actuating elements arranged on both sides thereof for adjusting the clamping element.

Since the support has a concentric cutout opening which covers the bearing part and both actuating elements, the adjustment of both clamping elements can be done without affecting the support.

To this end, the notch opening provided in the clamping element for accommodating the actuating element and the shaft is sized so that the clamping element can swing about the point at which it joins the actuating element. It is advantageous that

In order to drive the movable tightening element, each actuating element has a large number of slits provided at equal intervals, and the interlocking body and the projection of both tightening elements engage with these slits, and the adjacent supports are connected to each other. This is advantageously done by being able to rock against.

In a preferred embodiment of the method according to the invention, it is proposed that the support provided between the clamping elements is arranged at least axially fixed on the bearing part.

In the present invention, it is particularly advantageous that the support provided between the clamping elements is spring-elastic, in particular its outer region is axially movable.

By virtue of this spring-elastic formation, the clamping surfaces of the movable clamping elements easily come into contact with the clamping surfaces of the supports even when the supports are not arranged exactly concentrically between them.

Furthermore, it is advantageous for the clamping element to extend in a V-shape in its clamping position and to contact the respective support at its outer end.

In its clamping position, the movable clamping element extends in a V-shape and the support maintains its position on the supporting element in each operating position, that is to say the longitudinal axes of the supporting elements intersect each other at right angles. The angle between the clamping element and the support is smaller and therefore the contact area is increased. In this way, the edges located on the outside of the clamping element do not crush the gripped bristles as in the past, since the clamping element now contacts the support with a large area.

For this purpose, it is advantageous for the support to have, in the region of its outer end, two clamping surfaces, each of which extends V-shaped in the direction of the outer end of the support.

Furthermore, it is advantageous for the support, in the region of its outer edge, to have a thickness which is approximately the same as the thickness of the edge of the adjacent clamping element.

In a development of the device according to the invention,
The support has a clamping surface in the region of its outer edge, which clamping surface is formed as an arc segment, to which the clamping surface, which is formed as an arc segment of the clamping element, contacts over its entire edge. To do. This ensures that the bristles grasped by the clamping element and the support do not slip in the clamping position of the clamping element, because the clamping element is at least always in contact with the support at one point or in an all-planar arcuate segment. Guaranteed. The effective clamping action is enhanced by the fact that the clamping surface of the support and / or the movable clamping element is roughened or provided with grooves.

This guarantees that the hair is perfectly grabbed and cut without damaging the skin.

For this purpose, it is furthermore advantageous for the clamping surfaces of the support and / or of the movable clamping element to be made of a material with a high coefficient of friction.

In a preferred embodiment of the device according to the invention, at least the clamping surface of the support and / or of the movable clamping element is made of synthetic resin or metal with a high coefficient of friction.

In another embodiment of the invention, it is advantageous for at least the edges of the support to have a smooth surface.

Due to this advantageous shape of the clamping element and / or the outer edge of the support, skin trauma is avoided without the clamping effect being adversely affected thereby.

In another embodiment of the invention, it is advantageous for the edge of the support to extend over an arc which projects annularly from the adjacent clamping element.

Furthermore, the clamping element and the support can each consist of different material parts, the material in the clamping area having a greater coefficient of friction than the rest of the material parts, in particular those parts which are in sliding contact with the skin surface. It is advantageous.

Furthermore, it is advantageous if the clamping element and the support consist of a disc.

The clamping element and the support preferably consist of a disc with segmented cutouts.

In particular, the clamping element and the support consist of a disc with an annulus with a large number of equally spaced teeth.

Due to this advantageous embodiment of the differently formed tightening elements and supports, the threading process of the hair is advantageously influenced, or the hair is simply so that it can be grasped by the tightening elements and supports without problems. Be oriented or aligned with.

For this purpose, it is advantageous if at least the support with a large number of teeth or segmental cutouts is surrounded by a clamping element which is designed as a disc.

In another embodiment of the invention, it is advantageous for the support to consist of a central member and upper and lower edge parts each provided with two V-shaped clamping surfaces.

Moreover, the edge of the support may have the same thickness as the portion following the edge of the support or less, but thicker to accommodate the clamping surface.

Other advantages and details of the invention are set forth in the appended claims and specification and shown in the drawings. It should be noted that the features of the claims and combinations thereof have the essence of the present invention.

EXAMPLES The present invention will be described in detail below with reference to the examples shown in the drawings, but the present invention is not limited thereto.

In the drawings, reference numeral 1 is a partial cross-sectional view of a device for removing human hair or a hair removing device. The epilation device 1 comprises a housing 2 and a removable epilation head 3 for receiving a drivably supported rotating cylinder 4.

The rotary cylinder 4 is driven by the electric motor 10. The electric motor 10 is connected to a system power supply or a rechargeable storage battery 5 or a replaceable battery.

The drive motor 10 is drivably connected to the drive gear 8 of the rotary cylinder 4 via a number of gears 9 of the advanced gear transmission 7.

The epilation head 3 which can be inserted into the housing 2 has a left bearing shell 11 according to FIG. The bearing shell 11 is fixed or connected integrally with a horizontally extending support part 13. A right bearing shell 12 is further detachably connected to the support portion 13 and is fixed by a bolt 15 extending through a hole 14 provided in the bearing shell 12 and a screw hole 16 provided in the support portion 13. .

Bearing bushes 17 and 18 for receiving the shaft 19 are provided in the bearing shells 11 and 12, and the rotary cylinder 4 is rotatably supported by the bearing bushes 17 and 18. Cylindrical slit openings 2 are provided at both ends of the shaft 19, respectively.
There is 0. Legs 21 on either side of the clevis 22 shown in side view in FIG. 3 extend through their slit openings 20.

As can be seen from FIG. 2, two half-shell shaped threading elements 49, 50 are arranged on the left and right or above and below the fastening elements 42, 43 arranged side by side. These threading elements 49, 50 have a number of lamellas 51 arranged side by side and extending in parallel. These lamellas 51 have the purpose of orienting the hair so that it can easily enter the intermediate chamber 52 of the cooperating clamping elements 42, 43 and the support 73.

The threading elements 49, 50 are arranged in the bearing part 24 surrounding the shaft 19 and are releasably connected thereto. For this purpose, the threading elements 49, 50 have left and right projections 53, 56 with grooves 54, 57. The gear 8 is fitted in the groove 54 of the protrusion 53 located diametrically opposite to each other,
The disc 55 is fitted in the groove 57 of the threading elements 49, 50. When the gear 8 or the disc 55 is pushed in, both protrusions 53,
56 is a groove 5 to which the gear 8 or the circular plate 55 easily corresponds.
It deforms so as to enter 4, 57. In this way, on both sides of the threading elements 49, 50, the bearing part 2 of the shaft 19
4 and the threaded elements 49, 50 are tightened.

Furthermore, the gear 8, the disc 55 and the numerous clamping elements 42, 43 are provided with rectangular openings 59, 44, 61 respectively.
As a result, the clamping elements 42, 43 with actuating elements 26, 27, the gear wheel 8 and the disc 55 are fitted onto the bearing part 24. These parts are particularly suitable for the bearing part 24
It is a component of the rotary cylinder 4 which is rotatably supported by a shaft 19 of the rotary cylinder 4 via a gear and is driven by a gear 8.

Further, as can be seen from FIG. 3, the epilation head 3
The U-link 22 in FIG.
It is housed in. Other actuators may be used in place of the clevis 22 shown in FIG.

The shaft 19 of the rotary cylinder 4 of the epilation head 3 in FIG. 3 is used to rotatably receive a rectangular elongated central bearing part 24. The shafts 19 protruding from both sides of the bearing portion 24 are provided with slit openings 20 on the end face side.
It has a bearing pin 25 with.

Two actuating elements or actuating rods 26 and 27, which are respectively movable relative to each other, are supported on the upper and lower sides of the bearing portion 24 which are diametrically opposed to each other.

Further, as can be seen from FIG. 3, the operating rod 2
6 and 27, tightening elements 42 and 43, which are shown in detail in FIGS. 6 to 8, are arranged or interlocked with this. The number of fastening elements 42, 43 cooperates and each forms a fastening device for removing hair. This clamping device is part of the rotary cylinder 4. Two fastening elements 42, 4 which are arranged so that they can move relative to each other
Between the three, the support 73 which will be described in detail later operates.

Both upper working rods 26, 27 are shown in perspective view in FIG. One actuating rod 27 is formed in a U shape and has two rods 30 and 31 extending in parallel. These rods 30 and 31 are connected to each other via a web 32 that extends laterally on the end side. On the upper side surfaces of both rods 30 and 31 extending in parallel, there are a large number of slits 33 that are equidistant from each other, and these slits 33 form a right angle with the longitudinal side surfaces of the rods 30 and 31. The slit 33 of the operating rod 27 is located in the same horizontal plane as the slit 33 of the adjacent rod 30.

Both rods 30 and 31 extending in parallel form a U-shaped space 34 in which the operating rod 26 is accommodated so as to be movable in the axial direction. In FIG. 5, between the right end of the operating rod 26 and the laterally extending web 32, the operating rod 2
There is a spring 39 which normally holds 6 in its neutral position. In the position shown in FIG. 5, the actuation rods 26, 27
Is moved relative to the action of the spring 39 by a support or pressure roller 38 provided at the end of the actuating rod. After the actuating rods 26, 27 have been moved by the pressure roller 38, the actuating rod is again in the opposite direction via the spring 39 and the laterally extending stopper 37 provided on the actuating rod 26 is provided on the actuating rod 27. It moves until it collides with the stopper 36 that is holding. In this way the actuation rod 26 is prevented from slipping out of the gap 34.

As can be seen from FIGS. 3 and 5, on both side legs 21 of the U-link 22, there are pressing parts which can be formed as pressing rollers 38, respectively. In the position shown in FIG. 5, during the rotation process of the rotary cylinder 4, when the ends 32, 40 of the actuating rods 26, 27 are moved by the pressure roller 38, the pressure roller 38 causes the actuating rod 2 to move.
6, 27 are pressed against the action of the spring 39. The drive system shown in FIGS. 3 and 5 can be replaced by another drive system without the clamping action according to the invention being affected.

During the adjusting process, both rods 3 of the slit 41 provided in the operating rod 26 and the operating rod 27
The slits 33 provided at 0 and 31 move relatively,
In that case, the clamping elements 42, 4 arranged in the slit
Similarly, 3 also moves relatively.

In FIG. 5, since the disc 63 is auxiliary inserted between the pressing roller 38 and the end faces of the operating rods 26 and 27, the pressing roller 38 is attached to the operating rods 26 and 27 via the disc 63. Working, thus avoiding operating noise and wear.

FIG. 6 shows two clamping elements 42, 43 and a support 73, which are normally situated in close proximity to each other. The left and right tightening elements 42, 43 each have a rectangular notch opening 44. Left tightening element 4
There is a downward projection 46 on the upper side 45 of the two notched openings 44. Furthermore, on the lower side 45 of the cutout opening 44 of the left-hand tightening element 42 there is a cutout 47 which opens upwards. Support 7
3 is formed as a rectangular plate whose upper and lower edges are arcuate and is arranged axially displaceable exactly on the bearing part 24 between the two outer clamping elements 42, 43. For this purpose, the support 73 comprises the bearing part 24 and the two actuating elements 2.
It has a rectangular opening 44 through which 6 and 27 pass. Due to this, manufacturing tolerances are compensated for and the two outer clamping elements 42,
It is ensured that 43 always contacts support 73 without hindrance.

The left hand tightening element 42 shown in FIG. 6 is shown as the right hand tightening element rotated 180 °.
That is, the fastening element 43 has a notch 47 in the upper part and a protrusion 46 in the lower part. Both outer tightening elements 42, 43
Since there is a support 73 having a notch opening 44 without a protrusion 46 and a notch 47, this support 7
3 is movable over the bearing part 24 and both upper and lower actuating elements 26, 27. That is, since the support 73 can freely move in the axial direction between the outer tightening elements 42 and 43,
The outer clamping elements 42, 43 optimally contact the support 73 even when the support 73 is not exactly concentrically aligned between the outer clamping elements 42, 43.

A number of alternating fastening elements 42, 43, 73 together with the other parts form a device for removing hair.

For this purpose, the clamping elements are provided on the upper actuating rods 26, 27 shown in FIG. 5 and on the lower actuating rods 26, 27 not shown in FIG. The upper projection 46 of the clamping element 42 engages the slit 41 of the central actuating rod 26 and delimits the notch 47 in the interlocking body 4.
8 engages with the slits 33 of the rods 30 and 31 extending parallel to each other and facing each other. Due to the large opening 44 of the support 73, the actuating elements 26, 27
The outer clamping elements 42, 43 easily without affecting the
To drive.

The drive of the clamping elements 42, 43 takes place in the same way. Here, the two interlocking bodies 48 of the fastening element 42 are engaged in the slits 33 of the two outer rods 30, 31, so that the fastening element 42 is connected to the central actuating rod 26 via the upper projection 46 on the one hand and on the other hand on the other hand. Both lower side interlocking body 4
Both outer rods 30 of the U-shaped actuating rod 27 via
Driven to 31.

FIG. 4 (a) is a sectional view showing each tightening element 4
2, 43 are shown drivingly coupled to the upper and lower actuating rods 26, 27. The upper interlocking body 48 of the tightening element 43 is the actuating rod 27.
Engage the slits 33 on both sides of the same and the projections 46 of the same clamping element 43 engage the slits 41 of the central actuating rod 26.

FIG. 4 (b) is a cross-sectional view showing that the support 73 is axially movably mounted on the bearing portion 24 and is unaffected by the actuating elements 26, 27.

The operation of the hair removal device according to the present invention will be described with reference to FIGS. 7 and 8. Here, in order to better show the course of movement, the main parts, in particular the fastening elements 42, 43,
Only 42 ', 43' and the support 73 are shown.

In FIG. 7, the epilating device has a fastening element 4
2, 43 are in the neutral position before being placed in the tightened position.
In this neutral position all tightening elements 42, 43,
42 ', 43' and the support 73 extend parallel to each other.

By arranging one support 73 between the two fastening elements 42, 43 to 43, 42 respectively according to FIGS. 7 and 8, the fastening elements 42, 4
3 and 42 ′, 43 ′ in the region of the ends or the points S lying outside, a significant improvement of the clamping action with the respective support 73 is achieved. An angle .alpha.2 (see FIGS. 8 and 10) which is smaller than the angle .alpha.1 (see FIG. 9) of the known device is obtained when gripping the individual hair 71. As a result, the bristles 71 are caught in a very large area by the edges or surfaces facing inward or in contact with each other, as will be described later.

In the case of the embodiment according to FIGS. 7 and 8, this small angle α 2 formed by the clamping elements 42, 43 according to the invention and the support 73 is due to one clamping element 42, 4
3, 42 ', 43' in the plane of the actuating rods 26, 27 whose hinge points have the same distance to the axis of rotation of the rotary cylinder as in the other actuating rods 26, 27. it can. A further reduction of the angle α2 is also achieved by the support 73 being provided between the clamping elements 42,43.

Even if the tightening elements 42, 43, 42 ', 4
Even if the 3'hinge is not located in the plane of the actuating rods 26, 27, the support 73 causes a significant reduction of the angle .alpha.1 in FIG. Such reduction is shown in FIG.
Is shown in.

That is, the two upper operating rods 26, 27 are moved from the position shown in FIG.
When pressed in the direction of the arrow by the force F2 against the action of the clamping element 42,
The reference numeral 43 swings in the slits 33 and 41 located below the lower operating rods 26 and 27.

7 and 8, the left end of the spring 39 is in contact with the left spring receiver 89, and the right end thereof is in contact with the right spring receiver 90. Tightening elements 42, 42 ', 43, 4
As can be seen from the 3'position, this position is the actuating element 27.
The fastening elements 42, 42 ', 43, 43' are defined by a stopper 36 fixedly arranged on the
Is not adjusted beyond this position.

During the swinging process in FIG. 7, the upper spring 39
Is compressed in the length direction, and the lower spring 39 has its length L
Is maintained. On the one hand, the lower spring 39 is supported in contact with the left spring receiver 89, and on the other hand is supported by the right spring receiver 90 on the stoppers 36, 37, whereby the position shown in FIG. 8 is maintained.

As a result, the adjusting force of the movable tightening elements 42, 43 is also very small.

By satisfactorily substituting the rocking points of the movable clamping elements 42, 43 within the range of the movement trajectory of the actuating rods 26, 27, the adjusting force F2 for adjusting the clamping elements 42, 43 can be very small. This significantly reduces the frictional forces on all parts, which makes it easier to extend the life of the device. Since the adjusting force can be reduced by the arrangement shown, the structural parts of the epilation device can also be lightly dimensioned, thus reducing the overall production cost of the device.

In FIG. 9, the known pair of contacting clamping elements 42, 43 extend in a V-shape with respect to one another in their clamping position, an angle α 1 which is greater than the angle α 2 between the movable clamping element 42 and the support 73. Are formed.

Further, as can be seen from FIGS. 9 and 10,
The base width L1 is almost twice as large as the base width L2 in FIG. 10, and nevertheless, in the case of the embodiment of FIG. 10, the tightening capacity is doubled. This is the tightening element 4
This is advantageously achieved by a support 73 arranged between the two and 43. Three clamping elements 42 in contact with each other,
The total thickness of 43 and 73 is the sum of the respective thicknesses e of the tightening elements 42 and 43 and the support 73.

The support 73 has a thickness e in the region of its outer edge 75 (see FIG. 10), which is approximately the same as the thickness e of the edge 76 of the clamping elements 42, 43 which are in contact or adjoining each other. They are the same size.

Thus, if the two tightening elements 42, 43 and the support 73 only need to be thick enough on the bearing part 24, ie if the doubling the effective tightening element for removing hair, the device is It does not have to be as wide as a whole to accommodate the support, but rather is narrowly sized.

As can be seen from FIG. 9, the base width L1 of the four fastening elements (ie the two fastening elements 42,
The spacing between the outer lower edges of 43 is greater than the base width L2 of the two clamping elements 42, 43 and the support 73 in FIG.

Since the support 73 provided between the tightening elements 42 and 43 is formed with spring elasticity,
The outer region is preferably axially movable.

Further in accordance with FIG. 11, the support 73 has two clamping surfaces 74 in the region of its outer edge 75. These clamping surfaces 74 extend in a V-shape in the direction of the outer end of the support 73 and are denoted by 79, 80, 81, 82. This makes it possible to obtain a comparatively large clamping surface 74 which is formed as an arc segment 77 between the edges 79, 80.

Clamping elements 42, 43 and support 73
Since they contact at the contact surfaces 79 to 82, the tightening action is significantly improved. In that case, it is advantageous for the contact surfaces 79 to 82, which are characterized by corner edges, to be roughened or grooved for a better clamping action.

The support 73 may be rigidly arranged on the bearing part 24 or may be movably supported thereto at least in the axial direction. Furthermore, the rotary movement of the rotary cylinder 4 about its axis of rotation can be varied.

As can be seen especially from FIG. 10, the support 7
3 is somewhat longer than both movable clamping elements 42,43. This causes the inclined outer lateral edges 76 of the outer clamping elements 42, 43 to make the skin red, as they make no contact with the skin surface or with less pressure than the support 73. There is no.

Furthermore, the clamping elements 42, 43 and / or the support 73 can be made of two different materials,
In that case, the material in the clamping area has a higher coefficient of friction than the material in the edge area. This gives not only very good sliding properties, but also a good clamping action.

The support 73, which is advantageously manufactured, for example, of synthetic resin, in the working state undergoes little deformation as it is exposed to only small bending forces.

Furthermore, since the clamping elements 42, 43 as well as the radially extending sides 75, 76 of the support 73 are particularly smooth-polished, the skin surface has a clamping element 42, 43.
And when the support 73 comes into contact, it is treated with sufficient care. The advantageous embodiment of the clamping elements 42, 43 and the support 73 also allows the device to slide very softly on the skin surface, so that the pressing force of the device on the skin can also be increased. Since greater pressure can be applied to the skin, the pain typically caused by pulling on the skin when removing hair is also reduced when peeling hair.

In FIG. 12, the movable clamping elements 42, 43 and / or the support 73 without the threading elements 49, 50 can also be formed as a disc with a circular clamping surface 74 '.

Further in accordance with FIG. 14, the support 73 can be provided with notches or recesses 84 in order to improve the process of passing the hair through the clamping area. Instead of the recess 84, the movable clamping element 42, 43 and / or the support 73 according to FIG. 13 can be formed as a circular comb 85 with a large number of teeth 86.

Further, the support 73 shown in FIGS. 6 and 10 can be composed of the central member 83 and the upper and lower edge portions 92. The edge portion 92 has two clamping faces 74 diametrically opposed to each other and extending in a V shape.
Are provided (see also FIG. 10).

6 and 10, the edge portion 92 of the support 73 for receiving the tightening surface 74 is
The thickness e of the portion of the support 73 following the edge portion 92 may be equal to, or smaller than or larger than that.
