Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a hair removal device used to remove body hair for cosmetic purposes and the like.

[Conventional technology]

This type of hair removal device includes one that pulls out hair by sandwiching it between two rollers, as shown in Utility Model Publication No. 57-54725, and one that pulls out hair by sandwiching it between two rollers, and one that pulls out hair by sandwiching it between two rollers,
As shown in Specification No. 61, etc., by arranging a large number of discs and making the angles of adjacent discs different, a part of both discs in the circumferential direction pinches the hair and pulls it out. There is something.

[Problem to be solved by the invention]

However, the former method has a problem in that effective hair removal cannot be performed because the amount of hair caught between the rollers is small. In addition, in the latter case, each disc is designed to pinch the hair between adjacent discs at the same position in the circumferential direction and pull out the hair, so it is possible to pull out a large number of hairs efficiently. Since hair is pulled out from the entire disk at a certain position during one rotation of the disk, load fluctuations are large, hair is pulled out in several places at once, which causes a lot of stimulation, and furthermore, when the hair is pinched, The disks come into contact with each other, but since this contact is made on each disk at the same time, there is a problem in that the sound (tapping sound) generated by the contact is large. The present invention has been made in view of these points, and its purpose is to reduce load fluctuations, cause less stimulation, and
Furthermore, it is an object of the present invention to provide a hair removal device that is low in noise and has high efficiency in pulling out hair.

[Means to solve the problem]

Accordingly, the present invention includes a plurality of pairs of claws for holding the hair to be pulled out, a driving means for rotationally driving these claws, and a driving means for driving the pairs of claws toward each other during one rotation of the claws. The first feature is that the opening/closing means is provided with an opening/closing means for pinching the hair, and that the opening/closing timing of each set of claws by the opening/closing means is staggered. The second feature is that it is a means, and the third feature is that the contact width of the pair of claws is larger than the distance that the pair of claws moves while transitioning to contact. . [Operations] According to the present invention, since the timing of opening and closing of each set of nails is staggered, that is, the hair of each set of nails is pulled out sequentially at different timings, the concentration of load and the noise are reduced. There is no concentration of hair, and because many hairs are not pulled out at the same time, the stimulation is small. [Example] The present invention will be described in detail below based on the illustrated embodiment. This hair removal device is composed 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 11 is disposed within a housing 10 divided into two parts, and is provided with a power jack 14, a switch 15, and an intermediate gear 13 that meshes with a pinion 12 attached to the output shaft of the motor 11. The hair removal block 2 has a hook 16 protruding from the main body 1.
16, three pairs of caps 21 and 21 attached to the housing 20, cam plates 22 and 22 fixed to opposing surfaces of each cap 21, and both ends However, the bearing in the cam plate 22 is rotatably supported at the shaft 23,
A reduction gear 24 is attached to one end of the square shaft of the shaft 23 and meshes with the intermediate gear 13, a support plate 25 is attached to the other end of the square shaft of the shaft 23, and a collar 2 is attached to the square shaft of the shaft 23.
6, a plurality of disc-shaped claws 31 are attached at predetermined intervals, two claws 32 are provided between each of these claws 31, and the reduction gear 24 and the claws 31. and support plate 25 and claw 31. It is formed by a plurality of pins 27 of different lengths inserted so as to be able to freely slide in the axial direction. The molds 31 and 32 constituting the hair removal means are configured to rotate together with the shaft 23, and the square hole of the claw 32 through which the collar 26 is inserted is set to be larger than the back 26. The winter melon 32 is tilted freely in the direction around the axis of the shaft 23, and is in contact with one surface of each of the pins 27 (the claws 32 that are responsible for the outsiders). , are installed so that they are offset from each other,
In addition, the spring piece 33 that is cut and raised on the side opposite to the surface that the pin 27 abuts and projects comes into elastic contact with the adjacent claw 31, so that it is biased in the direction away from the adjacent claw 31. When the reduction gear 24, the shaft 23, the pawls 31, 32, and the support plate 25 rotate with the rotation of the shaft 23 by the motor 11, each pin 27 also rotates together with them. At this time, the cam plate 22.22 facing each outer surface of the reduction gear 24 and the support plate 25 has convex portions 22a, 22a on a part of its negative surface in the circumferential direction. When riding on the convex portion 22a, the claw 32 is pressed against the spring piece 33 to bring the tip of the claw 32 into contact with the adjacent claw 31. Since each pin 27 is sequentially shifted around the axis of the shaft 23 according to the arrangement of the claws 32, the motor 1
1, different pins 27 sequentially ride on the convex portion 22a of the cam plate 22, and therefore different pawls 32 are sequentially pressed by the pins 27 and come into contact with the pawl 31. This state is shown in FIGS. 5 to 7. Since the convex portion 22a of the cam 22 is positioned in the area indicated by α in FIG. is claw 31 and claw 32
When the space between the two is maintained, the hair enters between the two, and when the claw 32 comes into contact with the claw 31, the hair is caught,
The hair 9 is pulled out because the claws 31 and 32 continue to rotate for a while with the hair 9 sandwiched between them.Afterwards, the claws 31 and 32 open, causing the pulled hair to rotate. It is thrown outside by the centrifugal force that accompanies it. Further, as shown in FIG. 7, the contact width W of the pair of claws 31, 32 is larger than the distance l that the pair of claws 31, 32 moves while transitioning to contact. The hair 9 that has entered between 31 and 32 will be reliably pinched and pulled out. Furthermore, the hair 9 is pulled out sequentially between different claws 31 and 32 during one rotation, so the load when pulling out the hair 9 is distributed in a distributed manner during one rotation. Yes, - sometimes not concentrating, nails 31.
Since the sound when the hairs 9 come in contact with each other is the same, there is no loud noise, and from the user's point of view, the irritation is small because many hairs 9 are not pulled out at the same time. . Other embodiments are shown in FIGS. 8 to 13. Here axis 23
is fixed at both ends to the cap 21 so as not to rotate, and the reduction gear 24 and support plate 25 are rotatable with respect to the shaft 23. Also,
A sleeve 28 having a square hole to prevent rotation is attached to the square shaft portion of the shaft 23, and claws 31 and 32 are provided on the outer periphery of the sleeve 28 to prevent rotation relative to the sleeve 28. It is arranged so that it can be freely
A connecting pin 29 passing through the reduction gear 24, the winter melon 31, and the support plate 24 allows them to rotate together. Further, the pawl 32 is made to be able to freely tilt in the axial direction, and is urged in a direction away from the pawl 31 by a spring 36 disposed between the pawl 32 and the pawl 31. Also, the nail 31 has its hair 9
An engaging piece 34 is provided at the end opposite to the end for pinching, which engages with an engaging hole 33 provided in the pawl 31 to rotate the pawl 32 and the pawl 31 together. The claw 32 rides on the cam part 28a protruding from the collar 28 and the spring 3
6 is provided with a convex portion 35 that is inclined toward the claw 31 side. Now, if the motor 11 rotates the reduction gear 24, the support plate 25, and the pawls 31 and 32, the pawl 32 will rotate at its protrusion 3.
5 reaches the position where it rides on the cam portion 28a of the collar 28, it tilts against the spring 36 and comes into contact with the adjacent claw 31. Also in this case, since the winter melons 32 are arranged at different positions around the axis of the shaft 23, the different claws 31 and claws 32 come into contact with each other sequentially as the rotation is described above. . In this case, compared to the embodiment described above, since the claw 32 does not need to avoid the pin 27 for the other claw 32, the overlap between the claws 31 and 32 can be increased, and at the same time, the overall Miniaturization can be achieved. Incidentally, the spring 36 may be formed by cutting and bending the claw 32 as in the previous embodiment. FIG. 14 shows two sets of claws 31. in the above embodiment.
32 is shown in a developed view when they are brought into contact with each other at the same time. Another embodiment is shown in FIG. 15 and below. This is a trimmer 4 for trimming the hair to be pulled out by the hair removal means short in advance, and is provided on the front side in the direction in which the main body 1 is moved during hair removal. A fixed blade 41 that is slidably attached, a movable blade 42 that is attached to the fixed blade 41 via a pressing spring 44, a handle 40 that is provided on the fixed blade 41 and exposed on the surface of the main body 1, and a movable blade. 42 and a drive element 43 attached to the drive element 42. The driver 43 is formed by an annular convex rib 2 formed on the outer peripheral surface of the support plate 25 and displaced in the axial direction of the shaft 23.
5a, and as the support plate 25 rotates, the movable blade 4
2 to perform reciprocating motion, and by this reciprocating motion,
The hair 9 is cut between the comb-shaped blade portion of the fixed blade 41 and the comb-shaped blade portion of the movable blade 42. However, this trimmer 9 is suitable for long hair 9 or sleeping hair 9.
In order to raise the efficiency of introducing the hair 9 into the hair removal means and to ensure that the hair 9 can be pulled out by the hair removal means from the root, that is, the tip of the long, thick hair 9 is pinched by the hair removal means. The main purpose is to prevent the situation where the hair 9 cannot be pulled out simply due to the feeling of pain, as in the case of pulling the hair with The distance is set so that the length of the hair 9 cut by the trimmer 9 is suitable for pulling out the hair 9 by the hair removal means. In addition, if the fixed blade 41 is pulled up by operating the handle 40,
The movable blade 42 is also pulled up at the same time, and at the same time the drive element 43
It is also possible to prevent the trimmer 4 from cutting the hair 9 because the hair 9 comes off the convex rib 25a. Furthermore, even if a comb member having the same shape as the fixed blade 41 is arranged in place of the trimmer 4, it will not be possible to raise the sleeping hair 9 or raise the long hair 9.
It is possible to prevent the tip side of the hair from being pinched by the hair removal means before the root part, and the direction of the hair can be made parallel to the claws 31 and 32 of the hair removal means, thereby increasing introduction efficiency.

【Effect of the invention】

As described above, in the present invention, body hair is pulled out by sequentially opening and closing a plurality of pairs of claws, which results in less stimulation, less load fluctuation, and less noise, and moreover, during one rotation. Since all pairs of nails open and close, it is possible to perform hair removal with the same efficiency as that using the disc shown in the conventional example.
