Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shaving comb used in home barbers, and an object of the present invention is to provide a comb that can make hair stand up in order to make it easier to cut hair, which is difficult to do in home barbers. It is something to do.

BACKGROUND ART Conventionally, as shown in FIG. 1, a comb for cutting hair has been devised in which the rear ends of two combs are pivoted and can be opened and closed. However, with such a simple structure, the hair does not stand up sufficiently even when the comb is opened, so it is difficult to obtain the desired length of hair. In other words, as shown in Figure 1a, the long hairs at the top are concentrated at the back of the comb due to the weight and low elasticity of the hairs, so even if the comb is opened as shown in Figure 1b, the hair cannot be removed by the comb. The disadvantage was that the hair could not be made to stand upright because it had little effect of pushing the hair upward.

By the way, if we examine the comb operation in a barber shop in detail, we will first insert the comb into the hair, as shown in Figure 2a, and then, while turning our wrists, move the comb upward as shown in Figure 2b. By moving the comb upward in this way, the effect of pushing up and raising the hair becomes greater. However, this method requires skill and is difficult for amateurs. However,
The device disclosed in Japanese Utility Model Publication No. 43-3378 consists of a fixed comb and a movable comb, and the movable comb is rotatably mounted on a shaft at a position vertically away from the comb tooth surface of the fixed comb. Because it is supported, when the movable comb is rotated and separated from the fixed comb, the movable comb also moves toward the tip of the fixed comb, which is similar to the method of using the comb shown in Figure 2. It is becoming more and more popular. However, the amount of movement of the fixed comb towards the tip of the movable comb is small, and in order to increase this, the pivot point must be moved far away from the comb tooth surface of the fixed comb, which makes usability difficult. At the same time, the angle that the movable comb makes with respect to the fixed comb also increases, and if the hair is cut along the movable comb, the length of the hair will change steeply, resulting in a poor finish. It still has the problem of deterioration.

In view of these points, the present invention is capable of more faithfully reproducing the comb operation in the barber shop, and includes a fixed comb, a movable comb that is movable with respect to the fixed comb, and a movable comb that is movable relative to the fixed comb. , an L-shaped link fitting that connects the upper end of an upright plate that is erected substantially perpendicularly to the comb tooth surface from the comb tooth connecting portion of the fixed comb and the tip of the teeth of the movable comb; and an intermediate part of the upright plate. A second link fitting connects the movable comb to the base of the movable comb, and the second link fitting is rotated in conjunction with the operation of an operating section attached to the bent portion of the upper end of the upright plate via a return spring. It is characterized in that it consists of a rotation mechanism for moving the shaft.

The following description will be given based on the illustrated embodiment. FIGS. 3 to 7 show one embodiment. The fixed comb 2, which is integrated with the grip part 10 and has a crank-shaped cross section, has a comb tooth part 11 in a part separated from the grip part 10, and an upright plate 12 that connects the comb tooth part 11 and the grip part 10. Two holes 13 are provided in which a rotating member and a rotation fulcrum are provided. Further, on the extension of the grip part 10, a hole 15 into which a push button 14 is inserted and a hole 17 for positioning a slide plate 16 for adjusting the rotation angle (movement position) of the movable comb 1 are provided. Four holes 18 are provided in the upright plate 12, and pins 21 are press-fitted and fixed into the four holes via an L-shaped link fitting 19 and a second link fitting 20 of the rotating member. The link fittings 19 and 20 are rotatably mounted around the pin 21 as a rotational fulcrum.

Next, the movable comb 1 is provided with comb teeth portions 22 at the same pitch as the comb teeth portions 11 of the fixed comb 2, or at a pitch that is an integral multiple or a fraction of an integral number. Further, a rib 23 is provided at the rear end to serve as reinforcement for the movable comb 1 and a guide for the clipper blade, and behind the rib 23 there is a protrusion 25 having a hole 24 into which a rotating pin 21 is press-fitted. Similarly, protrusions 28 having holes 27 into which the pins 21 are press-fitted are provided on the thick teeth 26 at both ends of the comb-teeth portion 22 .

The link fitting 20 has pins 21 at both ends of the thin plate 29.
The comb has two holes 30 and 31 through which it passes, and the holes 30 on both sides in FIG. The 312 holes below the link fitting 20 are connected to the holes 24 of the protrusion 25 of the movable comb 1 with pins 21. Next, the two L-shaped link fittings 19 are
There are holes 32 and 33, and each hole 32 has a pin 21.
It is attached to the hole 18 of the upright plate 12 of the fixed comb 2, and the protrusion 28 at the tip of the movable comb 1 is attached to the other hole 33 by a pin 21. With the above structure, the link fittings 19 and 20 are attached so as to freely rotate about the pin 21 press-fitted into the fixed comb 2 and the movable comb 1 as a fulcrum.

In this state, as shown in FIG.
The movable comb 1 can be moved by pushing the L-shaped link fitting 19 forward, pulling it upward, or rotating it toward the tooth tips.
It rotates while moving forward, and changes the angle at irregular angles. This rotational movement is caused by the engagement of a pinion 35 provided at one end 34 of the link fitting 20 with a rack portion 36 formed at the lower part of the push button 14, as shown in FIG.
4 is moved up and down, the link fitting 20 rotates, and the movable comb 1 rotates as shown in FIG. push button 14
In order to automatically return the push button 14, a return spring 37 is inserted into the inner surface of the push button 14, and the push button 14 receives spring pressure from a spring receiver 39 fixed by a screw 38 from below. As another rotating mechanism, a pressing piece 3 is provided at one end of the L-shaped link fitting 19 as shown in FIG. There is also a way to move the .

However, in this state, the pushing position of the push button 14 is not constant, so it is not possible to obtain a constant cutting height and rotation angle necessary for cutting. Therefore, to disclose an example in which the pushing position of the push button 14 is fixed, as shown in FIG.
Insert the slide plate 16 having a
Adjustment plate 42 and spring 43 are set and hook 40
Press-fit and fix. The distance (a, b, c) that the push button 14 can move changes, the amount of pushing is regulated,
The amount of movement and rotation of the movable comb 1 is determined.

As shown in FIG. 13, by changing the press-fitting position of the pin 21 and changing the length of the link fittings 19 and 20, the rotational fulcrum changes, so the amount of forward movement, rotation angle, and cutting height of the movable comb 1 can be changed. etc. can be selected arbitrarily.

By the way, each tooth or multiple teeth of the tips of the fixed comb 2 and the movable comb 1 match, but in actual processing, it is impossible to perfectly match the pitch and shape, and if they do not match, the As shown in Figure 14a, the tip width of the comb teeth becomes wider, making it difficult to introduce the hair, and also making it difficult to operate the comb as the tip pulls the hair. Therefore, if the combs 1 and 2 are shifted in the front-rear direction as shown in FIG. 2B, the range that covers mismatched comb teeth becomes wider, and the possibility of the above-mentioned problem occurring is reduced.

As shown in FIG. 15, the dimension A between the bottom surface of the comb and the lower surface of the grip part 10 is set to prevent fingers from hitting the head and not being able to scoop the hair sufficiently when holding the comb to scoop hair. Furthermore, if the A dimension is made too large, the operating section and the operating section will be separated and it will be difficult to operate, so it is preferable to select the A dimension to be about 15 to 20 mm.

When using the cutting comb of the present invention,
First, a desired cutting height is selected using a slide plate 16, and then the grip part 10 of the comb is held to scoop up the hair, the comb is stopped at the desired cutting position, and the bottom surface of the fixed comb 2 is applied to the scalp without tilting. In this state, press the push button 14 with your thumb until it touches the adjustment plates 41, 42 and hold it as it is. Next, the hair protruding from the movable comb 1 as shown in FIG. 16b is cut off with clippers. At this time, the first
As shown in Fig. 7, if one end of the clipper blade is in contact with the rib 23 of the movable comb 1 and the other end is slightly floating, the clipper blade will not get caught on the comb teeth and can be smoothly cut. When the hair is cut in this way, the user removes the thumb from the push button 14, closes the movable comb 1, removes the comb from the head, and moves the comb to a new location.

By the way, when we measure the length of a boy's shaved hair, we find that as the length from the hem increases, as shown in Figure 18, the length of the hair also increases, as shown in Figure 18. Therefore, adjustment plates 41, 4
If the thickness of the movable comb 2 is appropriately adjusted and the fixed position of the movable comb 1 is set to match the above graph as shown in FIG. 19, the movable comb 1 can be continuously cut from the bottom as shown in FIG. 20. I can do it.

As described above, in the present invention, when the movable comb is moved via the second link fitting by operating the operating section, the movable comb separates from the fixed comb and at the same time moves toward the tip of the fixed comb. In addition, the connection point between the movable comb and the second link fitting, which is the center of rotation of the movable comb, is also connected to the second link fitting.
Because it moves with the rotation of the link metal fittings,
The fixed comb can be moved a large amount towards the tip of the teeth, ensuring that the hair stands up, and even when the movable comb is separated from the fixed comb,
The opening angle between the movable comb and the fixed comb is not very large, so even when cutting hair along the surface of the movable comb, the length of the hair does not change steeply, and the hair is cut from the hem. It can be finished beautifully.
