DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair removal device used for removing body hair for cosmetic purposes.

[0002]

2. Description of the Related Art An epilation apparatus of this type is disclosed in
U.S. Pat. No. 7,027,056, which utilizes the periodic opening and closing of a coil spring, and a disk-shaped rotary claw which is driven to rotate as disclosed in Japanese Patent Application Laid-Open No. 60-156407 or European Patent No. 328,426. There is a thing using.

[0003]

However, in the former case, the opening and closing stroke of the gap becomes large because there are many gaps for pinching after the hair is introduced for hair removal although the skin contact is good. In addition to this, there is a problem that the size is increased, and also a problem that short hairs cannot be removed. The latter one has a problem that the disc-shaped rotary claw requires rigidity and thus has poor skin contact. In both cases, since a large number of hairs are simultaneously pulled out, the feeling of irritation is strong, and since a large amount of hairs are simultaneously pulled out, a large force is required. The rigidity of the body must be high.

[0004] The present invention has been made in view of the above points, and it is an object of the present invention to provide a hair removal device which has a good skin contact and less irritation, and has a small load and a small operating sound. .

[0005]

According to the present invention, there are provided a plurality of depilatory claws formed of at least a pair of rods arranged in series in the axial direction and arranged in the circumferential direction around the rotating shaft. , axes each gap depilation claws gap between the end surfaces of the pair of rods is driven in the axial direction together are rotated around the axis of the rotary shaft are arranged in a straight line are arranged in such a circumferential direction to be opened and closed in the circumferential direction It is characterized in that it is arranged at a position shifted in the direction.

According to the present invention, since the depilation nails are formed of rods arranged in a pair of axial directions, a good skin contact can be obtained. , It is possible to obtain an object with a small stimulus and operation sound.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment.
And a hair removal block 2 having a built-in hair removal means. The main body 1 has the motor 11 disposed in a two-piece housing 10, a power jack 14, a switch 15, and a pinion attached to an output shaft of the motor 11. The gear 12 is formed as an intermediate gear 13 that meshes with the gear 12.

The epilation block 2 includes a pair of housings 20 and 21 connected by screws 45,
A pair of cam plates 22 fixed to opposing surfaces of
22, a rotating body 23 that is disposed between the cam plates 22 and 22 and that is rotatable around an axis on which shaft portions at both ends are supported.
And a plurality of epilation claws 3 disposed on the outer peripheral surface of the rotary member 23. A gear 24 meshing with the intermediate gear 13 is integrally formed on the outer peripheral surface at one end of the rotating body 23.

As shown in FIG. 4, each of the depilatory claws 3 is composed of a pair of straight rods 31 and 32 whose end faces are opposed to each other at a small interval.
The levers 35 are integrally formed with the levers 1 and 32, and a thin leaf spring portion 36 is also formed between the levers 35 . When the lever 35 is slidably engaged with the dovetail groove 25 formed on the outer peripheral surface of the rotating body 23, the epilating claw 3 is rotated.
23 is slidably mounted in the axial direction. The plurality of depilation nails 3 arranged in the circumferential direction of the rotating body 23
Is formed such that a gap formed by the elasticity of the leaf spring portion 36 between the rods 31 and 32 is located at a position shifted in the axial direction of the rotating body 23 .

Then, the depilation nail 3 is attached to the rotating body 23 as described above.
Is attached, the end of the lever 35 of the depilation claw 3 comes into contact with the cam plates 22, 22.
When the rotating body 23 is driven to rotate by the output of the motor 11, each of the depilation claws 3 is formed by the rotating body 23 because the gap between the rotating bodies 23 is reduced on the opening side of the housings 20, 21. The shafts are driven in the axial direction during one rotation. During this time, the end surfaces of the pair of rods 31 and 32 come into contact with each other at the opening side of the housings 20 and 21 against the elasticity of the leaf spring portion 36. A condition is to occur. FIG. 5 shows the movement at this time in order, and FIG.
A pair of rods 3 facing each other with a gap as shown in FIG.
The housings 1 and 32 are connected to the housings 20 and 2 as shown in FIG.
The end faces are brought into contact with each other when they reach the opening 1, and the hair is sandwiched between the rods 31 and 32 at this time, and the contact state is the position shown in FIG. 5 (c). Hair is pulled out to be maintained for a while.

At this time, a large number of hair removal claws 3 are attached to the rotating body 23. However, since only one clearance is used for each hair removal nail 3, a large number of hairs are simultaneously pulled out. The part of the depilation nail 3 which contacts the skin has an arc-shaped cross section, which has good skin contact and little irritation. Note that one of the pair of rods 31 and 32 constituting the depilation nail 3 may be integrated with the rotating body 23, and in this case, the one cam plate 22 can be omitted.

The hair removal claw 3 in the above embodiment forms the end surfaces of the rods 31 and 32 such that portions of a certain area come into contact with each other when the opposing surfaces of the rods 31 and 32 come into contact with each other. As shown in FIG. 6 and FIG.
1 and 32 are formed as inclined surfaces, and the rod 3
By forming a flat surface on the outer peripheral surface of each of the rods 1 and 32, the rods 31 and 32 may be brought into line contact with each other at the edges. Also, as shown in FIGS.
The rods 31 and 32 may be brought into contact with each other by line contact in the radial direction of 3, and in this case, the hair introduction efficiency also increases.

Further, a pair of rods 3 constituting the depilation nail 3
1 and 32 are integrally formed by connecting them with a leaf spring portion 36 so that the number of parts can be reduced. However, as shown in FIG. A spring 38 as a member may be interposed between both rods 31 and 32. As shown in FIG. 11, three or more rods 31, 32, 33 arranged in a straight line constitute the depilatory claw 3, so that two or more gaps for depilation are generated per one depilatory claw 3. In this case, any one rod may be integral with the rotating body 23.

The depilation nail 3 shown in FIG.
An elastic body 34 is provided at an intermediate portion of 1.
When the elastic body 34 is provided in this manner, the rods 31, 32
Can stabilize the force for pinching the hair. FIG.
As shown in (1), the entire depilatory nail 3 may be formed of an elastic body. In the figure, reference numeral 37 denotes a roller provided at a portion in contact with the cam plate 22.

FIG. 14 or FIG.
As shown in (2), if the concave portion 39 is provided at the same axial position as the gap in the other depilatory claw 3, it becomes easier to introduce hair into the gap.

[0016]

As described above, in the present invention, since the depilation nail is formed by a pair of rods arranged in the axial direction, a good skin contact can be obtained, and at the same time, the skin contact can be reduced.
Are those not requiring a member for improving, also open
A pair of rods that form a gap to be closed around the rotation axis
In addition to being able to place many
Dispose the gaps between the bristle nails in the axial direction in the circumferential direction.
Because it is provided, the number of gaps for hair removal can be set to an appropriate number, and at the same time, hair is pulled out sequentially when it is shifted in the axial direction, so that the feeling of irritation, load and operation sound is small. And the rigidity required for the main body is low.
