DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to an example of an embodiment. As shown in FIGS. A frame 2 formed in two and housed in a housing 1, and is supported by the frame 2 so as to be freely rotatable around an axis, and is rotated around the axis by a motor 3 mounted on the frame 2. The rotating body 4 is formed of a cylindrical rotating body 4 and a head cover 5 provided with a window 50 for exposing a part of the rotating body 4. The switch 10 is provided on the outer surface of the housing 1 having a jack portion 11 for power supply connection on the lower end surface.

The frame 2, which is connected and fixed with the motor fixing plate 20 interposed therebetween, has a gear 31 meshing with a pinion 30 attached to an output shaft of the motor 3, and a rotating body 4 meshing with the gear 31. And the gear 32 that meshes with the gear portion 40 are mounted by shafts 21 and 22, respectively. The rotating body 4 rotates around the axis by the rotation of the motor 3. If the meshing ratio is set to 2 or more by using a helical gear or a high gear in the gear train, the driving noise of the gear can be reduced. In the figure, reference numeral 23 denotes a screw connecting the two frames 2, and reference numeral 24 denotes an engagement hole with which the boss 14 formed on the inner surface of the housing 1 is engaged.

A pair of depilation claws 7, 7 is provided at equal intervals in the circumferential direction of the rotating body 7 and in the axial direction of the rotating body 7, Ten pieces are arranged with being shifted little by little. Further, the depilation claw 7 in this example includes a fixed claw 45 provided integrally on the outer peripheral surface of the rotating body 4 and a rotating body 4.
And a movable claw 70 attached to the main body.

The movable claw 7 of the pair of depilatory claws 7, 7
Numerals 0 and 70 pass through the claw mounting base 73, the fulcrum plate 75, the spring 78, and the holes 71 of both movable claws 70,
The block is formed by a shaft 77 that is inserted into the hole 74 of the rotary member 4, and is attached to the rotary member 4 by arranging the block in a concave portion 44 provided on the outer peripheral surface of the rotary member 4. The shaft 77 is inserted from the end face of the rotating body 4 and is fixed by sealing.

The pair of movable claws 7 attached in this manner
8, 70 are fixed claws 45 of the rotating body 4 as shown in FIG.
Are supported by a portion sandwiched between a fulcrum protrusion provided on the surface on the side of the recess 44 and the fulcrum plate 75 as a fulcrum, and a compression coil type spring 7 is interposed therebetween.
8, the movable claw 70 is urged in a direction away from the fixed claw 45. The fulcrum plate 75 may be integrated with the claw mounting base 73.

A plurality of holes 42 penetrating in the axial direction are provided in the rotating body 4 at equal intervals on a concentric circle, and slide levers 81 and 82 as opening / closing members of the depilation claw 7 slide in these holes 42. Mounted freely. Here, one end of the slide lever 81 is brought into contact with one of the pair of movable claws 70, 70 arranged on one end side of the rotating body 4, and the slide lever 82 is connected to the other end of the rotating body 4. The other end of each of the slide levers 81 and 82 protrudes from both end surfaces of the rotating body 4.

On the other hand, in the portion of the frame 2 which receives the shaft 49 for the rotating body 4, the roller type cam 6 has a shaft 60.
It is attached so that it can rotate freely. This cam 6
Are a plurality of slide levers 81 and slide levers 8 arranged in the circumferential direction of the rotating body 4 when the rotating body 4 rotates.
The movable claw 70 is swung against a spring 78 by sequentially pushing the other end of 2 and moving it in the axial direction of the rotating body 4 to close the depilatory claw 7 composed of the movable claw 70 and the fixed claw 45. However, a plurality of slide levers 81 disposed at one end of the rotating body 4 have a contact portion 83 with the cam 6 on the outer peripheral side and a contact portion 84 with the cam 6 on the inner peripheral side. Are alternately mounted in the circumferential direction of the rotating body 4, and a plurality of slide levers 82 arranged on the other end side of the rotating body 4 have a contact portion 86 with the cam 6 on the outer circumferential side. The rotating body 4 and the rotating body 4 are alternately mounted with the rotating body 4 and the rotating body 4 having a contact portion 85 with the cam 6 on the inner peripheral side. As is clear from FIG. 9, the contact portion 83 and the contact portion 84 of the slide lever 81 are overlapped in the radial direction with a shift of half a pitch. The contact portions 85 and 86 are also overlapped in the radial direction with a shift of a half pitch.

For this reason, when the rotating body 4 rotates, the slide levers 81 and 82 which come into contact with the cams 6 and 6 move to the rotating body 4.
In order to sequentially open and close the depilatory claw 7 in the circumferential direction of the rotating body 4, the slide lever 81 and the slide lever 82 adjacent to each other in the circumferential direction of the rotating body 4 are in contact with the cam 6 at the same time. Fit 2
A state in which the two depilation claws 7 are closed is generated. As a result, despite the fact that many depilation claws 7 are arranged in the circumferential direction of the rotating body 4, each epilation claw is removed. The closed state in which the movable claw 70 and the fixed claw 45 are in contact with each other is maintained for a long period of time with respect to the claw 7, so that the long hair caught by the depilation claw 7 is closed in terms of time and distance. It can be pulled for a long time, so that long hairs can be reliably pulled out.

As is apparent from FIG. 9, the adjacent slide levers 81 (slide levers 82) overlap approximately half the length in the circumferential direction, and every other slide lever 81 (slide lever) When the cam 6 comes into contact with 82), the load fluctuation can be reduced by the slide lever 81 (slide lever 82) between them.

The cams 6 of the slide levers 81, 82
While the sides are shifted in the radial direction, the contact portions of each of the slide levers 81 and 82 with the movable claw 70 are located on the same circumference, and the movable claw 70 swinging around the fulcrum. The same lever ratio acts on them.

The arrangement of the plurality of depilatory claws 7 with respect to the rotating body 4 is shifted in both the circumferential direction and the axial direction as described above, but from the end face of the rotating body 4 to the movable claw 70. Are set to five combinations (La, Lj and Lb, Li and Lc, Lh and Ld, Lg and Le, Lf) for a total of 10 pairs of depilation nails 7. Therefore, the number of components can be reduced by using a common one for the slide levers 81 and 82. The reason why the front and rear portions (both circumferential ends of the rotating body 4) of the movable claw 70 are bent in a direction away from the fixed claw 45 is to introduce hair into the space between the movable claw 70 and the fixed claw 45. It is not possible to increase efficiency.

As shown in FIG. 11, the slide lever 8
By setting the contact portion with the cam 6 to obliquely intersect the circumferential direction of the rotating body 4 as 1, 82, the period during which the epilation claw 7 is closed can be lengthened.

FIG. 12 shows another example. This is because a slide lever 81 (slide lever 82) having a contact portion 83 (contact portion 86) with the cam 6 on the outer peripheral side is replaced with a thin hinge piece 88.
And a slide lever 81 (slide lever 82) having a contact portion 84 (contact portion 85) with the cam 6 on the inner peripheral side via a thin hinge piece 89. In this figure, the parts are integrally connected to each other to improve the assemblability. As shown in the illustrated example, if the slide levers 81 and 82 are prevented from falling off by being connected to the stepped boss 49 provided on the end surface of the rotating body 4 and sealed, the assemblability can be improved in this respect as well. Can be. The boss 49 is stepped because of the hinge 88,
This is to regulate the height of 89. Each hinge piece 8
9 has elasticity in the axial direction of the rotating body 4 and does not hinder the independent movement of each slide lever 81, 82.

[0026]

As described above, according to the present invention, a plurality of depilation claws disposed on the outer peripheral surface of a cylindrical rotating body driven to rotate are opened and closed by an opening / closing member driven as the rotating body rotates. In a hair removal device that performs hair removal, since the adjacent opening and closing members of the plurality of opening and closing members that individually open and close each depilation claw are arranged to overlap in the radial direction, the circumferential length of each opening and closing member is increased. It can extend the period during which the epilation claw is closed, and can extend the pull-out distance of the hair without increasing the outer diameter of the rotating body. Can be good.

In this case, the opening / closing member is formed as a slide lever that extends in the axial direction of the rotating body and has one end as a contacting part with the epilating claw and the other end as a contacting part with a cam arranged beside the rotating body. With this configuration, the configuration of the opening / closing member can be simplified and the assemblability can be improved.

Further, by arranging the plurality of slide levers along the circumferential direction of the rotating body and displacing them in the radial direction, the pull-out distance of the hair can be more reliably increased. it can.

By making the adjacent slide levers overlap in the radial direction about half the length in the circumferential direction, it is possible to obtain the one in which the driving load of the opening / closing member is small.

Further, if adjacent slide levers are arranged so as to intersect with the circumferential direction, the contact portions on the cam side of the respective slide levers can be formed in the same shape, and the configuration of the slide levers Becomes easier.

If a plurality of slide levers are integrally formed, the assemblability is improved. Adjacent slide levers are integrally formed by a thin hinge piece having elasticity in the axial direction of the rotating body. By connecting the hinge piece to the rotating body, the slide lever can be smoothly moved and the load fluctuation can be reduced. If the hinge piece is attached to the rotating body, the slide lever can be prevented from coming off from the rotating body. The assemblability is improved.

Further, the abutment portions on the epilation claw side of the plurality of slide levers are located on the same circumference, and the abutment portions on the cam side are alternately shifted in the radial direction, so that a large number of slide levers are provided. Also in the case of the provided, the pinching force of the hair by the depilation nail can be made equal.

If a plurality of depilation nails are arranged so as to be shifted in both the circumferential direction and the axial direction of the rotating body, the hair removal efficiency of the hair can be increased, and the movable claw that is swingably supported can be used. With the movable claw, the movable claw has a swing fulcrum between the portion for holding the hair and the driven portion by the opening / closing member, so that the driving load for opening / closing the depilatory claw can be reduced. .
