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

0002

[Prior Art] This type of hair removal device was developed in Japanese Patent Application Laid-open No. 52
-A disc-shaped rotating pawl that utilizes the periodic opening and closing of a coil spring as shown in Japanese Patent Publication No. 72670, or a disc-shaped rotary claw that is rotationally driven as shown in Japanese Patent Application Laid-open No. 156407/1983 or European Patent No. 328426. There are some that use

[Problem to be Solved by the Invention] However, although the former method feels good on the skin, there are many gaps for inserting the hair into the hair for hair removal, so the opening/closing stroke of the gaps becomes large. As a result, there is a problem that the hair becomes large, and there is also a problem that short hair cannot be pulled out. The latter method has a problem in that it does not feel good against the skin because the disk-shaped rotating claw requires rigidity. In addition, both of these devices have a structure that removes a large number of hairs at the same time, which causes a strong sense of stimulation, and requires a large amount of force to remove many hairs at the same time. The rigidity of the main body must also be high.

[0004] The present invention has been made in view of the above points, and its purpose is to provide a hair removal device that feels good on the skin, causes less irritation, has a smaller load, and produces less operating noise. .

[0005]

[Means for Solving the Problems] According to the present invention, a plurality of hair removal claws each formed of a pair of rods arranged in series in the axial direction are disposed circumferentially around a rotating shaft, These hair removal claws are driven to rotate around the axis of rotation and are also driven in the axial direction to open and close gaps between a pair of rods.The feature of these hair removal claws is that each gap is disposed at a position shifted in the axial direction. have.

According to the present invention, since the hair removal nail is formed of a pair of rods arranged in the axial direction, good contact with the skin can be obtained, and the number of gaps for hair removal can be set to an appropriate number. Because it can be set to , it is possible to get a feeling of stimulation and a small operation sound.

[0007]

[Embodiments] The present invention will be described in detail below based on the illustrated embodiments. This hair removal device consists of a main body 1 having a built-in motor 11 and a hair removal block 2 having a built-in hair removal means. The motor 1 is placed inside the housing 10 which is divided into two parts.
1, as well as the power jack 14 and switch 1.
5, and pinion 1 attached to the output shaft of motor 11
2 and is provided with an intermediate gear 13 that meshes with the gear 2.

The hair removal block 2 includes a pair of housings 20 and 21 connected by a screw 45, and both housings 2
a pair of cam plates 22 fixed to opposing surfaces of 0 and 21, respectively;
22, a rotary body 23 disposed between the cam plates 22, 22 and capable of freely rotating around an axis on which the shaft portions at both ends are supported;
A gear 24 that meshes with the intermediate gear 13 is integrally formed on the outer peripheral surface of one end of the rotating body 23.

As shown in FIG. 4, each hair removal nail 3 here is composed of a pair of rods 31 and 32 arranged in a straight line with their end surfaces facing each other with a small interval between them.
, 32 are integrally formed with levers 35, 35, and a thin plate spring portion 36 is also integrally formed between the levers 36. The hair removal claw 3 is attached to the rotating body 23 by the lever 35 being slidably engaged with a dovetail groove 25 formed on the outer peripheral surface of the rotating body 23.
It is attached so that it can slide freely in the axial direction. Note that the plurality of hair removal claws 3 arranged in the circumferential direction of the rotary body 3 have gaps formed by the elasticity of the leaf spring portions 36 between the rods 31 and 32 at positions shifted in the axial direction of the rotary body 3. It is formed like this.

[0010] In this way, the hair removal nail 3 is attached to the rotating body 23.
When the hair removal claw 3 is attached, the end of the lever 35 on the hair removal claw 3 comes into contact with the cam plates 22, 22, but both cam plates 2
2 and 22 are formed so that the spacing becomes narrower on the opening side of the housings 20 and 21, so when the rotary body 23 is rotationally driven by the output of the motor 11, each hair removal claw 3 It is driven in the axial direction during one rotation, and during this period, the end surfaces of the pair of rods 31 and 32 are connected to the leaf spring portion 3 at the opening side of the housings 20 and 21.
A state of contact occurs against the elasticity of 6. Figure 5 shows the movements at this time in order, and Figure 5(a)
A pair of rods 31 and 32 facing each other with a gap as shown in FIG.
When reaching the openings 0 and 21, the end surfaces are brought into contact with each other, and at this time, the hair is transferred to the rods 31 and
The above-mentioned contact state is shown in Fig. 5 (
c) The hair is to be plucked out to maintain it for a while at the position shown in .

At this time, many hair removal nails 3 are attached to the rotating body 3, but since the gap used for hair removal is only one for each hair removal nail 3, many hairs may be pulled out at the same time. The part of the hair removal nail 3 that comes into contact with the skin has an arcuate cross section, which not only feels good on the skin but also causes less irritation. Note that one of the pair of rods 31 and 32 constituting the hair removal claw 3 may be integrated with the rotating body 23, and in this case, one of the cam plates 22 can be omitted.

In the hair removal nail 3 in the above embodiment, the end surfaces of the rods 31 and 32 were formed so that when the opposing surfaces of the rods 31 and 32 came into contact with each other, portions of a certain area were in contact with each other. As shown in FIGS. 6 and 7, the rod 3
1 and 32 are formed with inclined surfaces, and the rod 3
By forming a flat surface on the outer peripheral side of the rods 1 and 32, the rods 31 and 32 may be brought into contact with each other through line contact at the edges. In addition, as shown in FIGS. 8 and 9, the rotating body 2
The rods 31 and 32 may be brought into contact with each other by line contact in the radial direction of the rods 3, and in this case, the efficiency of introducing the bristles is also increased.

Furthermore, a pair of rods 3 constituting the hair removal nail 3
1 and 32 are connected by a leaf spring part 36 to reduce the number of parts, but as shown in FIG. A spring 38 as a member may be interposed between both rods 31 and 32. As shown in FIG. 11, the hair removal nail 3 is configured with three or more rods 31, 32, 33 arranged in a straight line, so that two or more gaps for hair removal are created for each hair removal nail 3. Alternatively, one of the rods in this case may be integral with the rotating body 23.

The hair removal nail 3 shown in FIG.
1 is provided with an elastic body 34 in the middle. When the elastic body 34 is provided in this way, the rods 31, 32
The force that pinches the hair can be stabilized. Figure 13
As shown in , the entire hair removal nail 3 may be made of an elastic material. In the figure, numeral 37 is a roller provided at a portion that comes into contact with the cam plate 22.

14 or 15 on the outer circumferential side of the hair removal nail 3.
As shown in FIG. 3, if the recess 39 is provided at the same axial position as the gap in the other hair removal nail 3, it becomes easier to introduce hair into the gap.

[0016]

[Effects of the Invention] As described above, in the present invention, since the hair removal nail is formed of a pair of rods arranged in the axial direction, it is possible to obtain good contact with the skin and also to remove short hairs. In addition, the number of gaps for hair removal can be set to an appropriate number, and at the same time, the hair is pulled out sequentially at positions shifted in the axial direction, so that the feeling of stimulation, load, and operation noise are small. The rigidity required for the main body is also low.
