DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multiple comb in which multiple rows of comb teeth are arranged in parallel and a method of manufacturing the same. Many of the materials of the multi-comb are hard materials such as non-rust metal or synthetic resin having some flexibility.

[0002]

[Prior art]

A well-known prior art related to the present invention includes a plurality of rows of comb-tooth plates composed of comb teeth and a comb seat in which the comb teeth are arrayed, and includes the comb teeth row. The entire comb is integrally formed, and the tips of the comb teeth are arranged side by side.

A conventional method of manufacturing a multiple comb is shown in FIG.
As shown in the figure, since the surface of the comb teeth needs to be entirely smooth on the comb, in general, the comb teeth are combed so that the molding cavity does not separate in the middle of the comb teeth. It is molded by a molding cavity having a continuous cone-shaped hole from the root, and the comb seat portion is molded by using another molding cavity.

In other words, a cavity space formed by a female cavity of a comb tooth portion or a comb seat including the comb tooth and a female cavity of a back portion of the comb tooth seat,
A plastic material such as a fluid synthetic resin is injected, and after the plastic material is solidified, the plastic material is removed from the cavity.

[0006]

[Problems to be solved by the invention]

In the conventional manufacturing method, as shown in FIG. 11, since the comb teeth 101 are formed in a cone shape, a step of extracting the formed product 100 having multiple rows of comb teeth from the cavity PQ. In the above, if a synthetic resin material having a considerable degree of elasticity is used, what is called "forcible extraction" may be performed by utilizing the elasticity, but the extracted product may be damaged.

When a plastic material having poor elasticity, for example, a hard synthetic resin, is used, it is impossible to perform the above-described “forced removal” without damaging the product. Must match. In other words, all the comb teeth have to be installed almost in the comb seat,
Also, the direction in which the comb teeth are provided must match the direction in which the molded product is extracted from the cavity.

Therefore, according to this conventional manufacturing method, it is impossible to manufacture any other than a multiple comb in which the width of the comb tooth or the root of the comb tooth and the width of the tip surface of the comb teeth match. Such a multiple comb has a problem in that the area of the surface comb portion must be narrower than the width of the comb tooth root portion.

In the conventional multiple comb, the tips of the comb teeth are arranged side by side and almost no step is provided at the end of the comb teeth. Therefore, the number of comb teeth plates is three or more. When the density of the comb teeth or the thickness of the comb teeth portion increases, fine combing can be performed, however, the amount of vigorous hair clipping also increases, and there is a problem that the combing tends to be difficult.

However, in order to solve this problem, if a coarse-grained comb is used, combing becomes easy,
There has been a problem that the combing effect cannot be sufficiently obtained, and in particular, the combing of the hair surface layer becomes coarse.

In view of such a problem, the present invention expands the range of the combed portion surface layer as compared with the conventional comb in which the width of the comb teeth is substantially the same from the base of the comb teeth to the tip thereof, Even if combing is smooth and the combing effect of the surface layer of the hair is high, the product may be damaged even if such a comb is made of a plastic material having low elasticity such as a hard synthetic resin. It is an object of the present invention to provide a manufacturing method which can be easily taken out of a cavity without providing the same.

[0013]

SUMMARY OF THE INVENTION According to the present invention, there is provided a comb tooth plate having a structure in which a plurality of rows of comb teeth are arranged and a plurality of rows of comb teeth are arranged in a comb tooth seat. These comb-tooth plates are independent separate members, and are fixedly connected in a double row.
In the multiple comb in which the inner comb tooth plates are sandwiched between two outer comb tooth plates and each comb tooth plate is fixedly connected in parallel, each comb tooth plate is made of a hard plastic synthetic resin, and A configuration in which a comb row of the outer comb-tooth plate or a comb row of comb-tooth plates adjacent to or adjacent to the outer comb-tooth plate is outwardly tapered at a slight angle toward the outside, and The main problem solving means is a configuration in which a step is provided between the comb tooth tip rows composed of the comb tooth tips of the comb tooth plate.

Further, according to the present invention, the surface formed by the comb teeth tapered or tapered at a slight angle toward the outer side and the comb teeth not tapered is formed so as to have a curved shape conforming to the shape of the skull. The configuration which is a surface can be taken as an auxiliary means for solving the problem.

In the above means for solving the auxiliary problem,
In the present invention, it is possible to adopt a configuration in which the tip of the inner comb tooth row is recessed from the surface formed by the tip of the comb tooth row of the two outer comb tooth plates.

The present invention provides a means for solving the above problems,
As a means of solving the problem in terms of the manufacturing method, the comb-tooth plates, which are constituent members of the multi-comb, are integrally formed as parallel members as separate members, respectively, as a first step. A manufacturing method in which the comb tooth plates are connected and fixed via the connecting means as two steps is a means for solving the problem for avoiding forced removal from the cavity.

[0017]

[Action]

With the above arrangement, the multiple comb of the present invention has a structure in which the tip surface of the comb teeth is wider than the width of the comb teeth or the roots of the combs. Compared to a conventional product having the same width on both the tip surface, the range of the surface comb portion is wider than the width of the comb root portion, and the combing efficiency is very good.

If the combing surface is formed as a curved surface conforming to the shape of the skull, the combing efficiency is improved from the surface layer of the hair to the deeper part of the hair close to the surface of the skull. The combing feeling during hair is very good.

Alternatively, in a multiple comb having such a comb-tooth plate structure, the tip of the inner comb tooth row is recessed from the surface formed by the tip of the comb tooth row of the two outer comb tooth rows. For example, if a step is provided between the comb tooth tip rows composed of the comb tooth tips of the respective comb tooth plates, the length of the comb teeth is longer than that of the conventional product in which the tips of the comb teeth are aligned. However, the comb teeth formed by the tips of the long comb teeth have a low density of comb teeth, so that the combing is facilitated.

In addition, if the tip of the short comb tooth is in contact with the hair surface or slightly fits into the hair, there is no difficulty in combing and the comb density on the hair surface is low. Can be combed while keeping the density close.
Further, if the handle is appropriately extended to the comb tooth seat, it is more usable.

In such a product, since the comb-tooth plate members are separately formed by the above-described manufacturing method, a plurality of comb-tooth plates are extracted from the cavity in the step of extracting the comb-tooth plates from the cavity. It is no longer necessary to match the removal direction, which has become an essential condition, with the direction in which the comb teeth are erected, and even when a hard material is used, it is easily removed from the cavity without damaging product components. It is possible to assemble these in the above procedure,
An undamaged product is provided.

FIG. 1 is an exploded view showing each member and assembling procedure of a multiple comb according to a first embodiment of the present invention.

As shown in FIG. 1, the present embodiment
It is composed of two outer comb plates 1, 2 having a matching symmetrical shape and one inner comb plate 3.

The first outer comb tooth plate 1 has thirteen long comb teeth 4a to 4m in the form of a core tube having a rounded end, which are arranged side by side in the outer comb tooth seat 5a. The outer exposed surface of the outer surface is a smooth and convex outer convex curved surface, and the inner surface thereof, that is, the side that is not exposed when the product is completed, is provided with six solid members serving as a means for inserting and combing the inner comb tooth plate 3. Rod-shaped fitting projections 6a-
f, a solid rod-shaped fitting projection 6g formed on the surface directly abutting on the second outer comb tooth plate 2 without the intervention of the inner comb tooth plate 3 when the product is completed.
Is protruding.

The plane formed by these seven solid rod-shaped fitting projections 6a to 6f is parallel to the plane formed by the comb tooth row.
The tip of 6 g also coincides on this plane. The rod lengths of the fitting projections 6a to 6f are slightly shorter than the thickness of the inner comb tooth plate 3.

Like the first outer comb tooth plate, the second outer comb tooth plate 2 also has thirteen solid rod-shaped long comb teeth 4n to 4z arranged in the outer comb tooth seat 5b. The outer surface of the outer comb tooth seat 5b is a smooth, richly designed outer convex curved plane having a symmetrical shape with the comb tooth seat 5a of the first outer comb tooth plate. Six bottomed cylindrical fitting projections 7a to 7f serving as a sandwiching means of the plate 3 and a fitting projection fitting hole 7g are formed on a surface directly abutting on the first outer comb tooth plate 1 when the product is completed. Has been established.

The bottomed cylindrical fitting projections 7a to 7f are externally fitted and fixed to six solid rod-like fitting projections formed on the first outer comb-tooth plate 1, and the fitting projection fitting holes 7g are formed in the first outer comb toothing holes 7g. The outer comb tooth plate is externally fitted to a solid bar-shaped fitting projection 6g provided in another projection. As in the case of the first outer comb tooth plate, the plane formed by the protruding ends of the six bottomed cylindrical fitting projections 7a to 7f is parallel to the plane formed by the comb tooth row, and the cylinder length is the inner comb tooth plate. 3 is almost the same.

Long comb teeth 4a to 4m formed on the first outer comb tooth plate 1
And the long comb teeth 4n-z formed on the second outer comb tooth plate 2 are opposed to 4a and 4n, 4b and 4o, 4c and 4p because both outer comb tooth plates 1 and 2 have a matching symmetric shape. Up to 4 m and 4 z, the two opposing rods have the same comb tooth length. Further, as shown in FIG. 2 which is a perspective view of the finished product of this embodiment, the tips of these comb teeth are arranged on the comb tooth row
Although a is a curved surface, they are arranged on the same straight line, which may also be called the outer comb tooth tip straight line, and are arranged side by side.

As shown in FIG. 1, the inner comb tooth plate 3 has 14 short comb teeth 10a to 10n arranged in an inner comb tooth seat 9, and two short comb teeth 10a to 10d arranged in two outer comb tooth plates. Like the long comb teeth 4a to 4m, a round surface is provided. Also, the tips of the short comb teeth 10a to 10n are arranged on the same straight line, similarly to the outer comb tooth plate, even though the comb tooth row setting surface 9a of the inner comb tooth seat 9 is a curved surface. In addition, they are arranged side by side. However, the tips of the short comb teeth 10a to 10n are, as shown in FIG.
Normally about the thickness of human hair than the straight line of the outer comb tooth tip,
It is recessed in the direction of the comb root.

In the inner comb tooth plate 3, a fitting protrusion insertion hole 1 for inserting a fitting protrusion protruding from a comb tooth seat of the two outer comb tooth plates.
1a to 1f are drilled at six locations. Both outer comb tooth plates 1,
Fitting projections 6a-f and 7a-
f is internally fitted into these fitting projection insertion holes 11a to 11f except for the fitting projection 6g formed at the end opposite to the gripping plate 12 of the comb. The solid rod-shaped fitting projection 6g and the fitting projection fitting hole 7g are fitted without interposing the inner comb tooth plate 3.

A first outer comb tooth plate having such a configuration,
Each member of the second outer comb tooth plate and the inner comb tooth plate is injected with a fluid plastic synthetic resin into a cavity female mold, integrally molded as a first step, and then as a second step as shown in FIG. ,
Seven solid rod-shaped fitting projections 6a to 6f which are comb tooth plate joining means
And 6g, respectively, are fitted to the bottomed cylindrical fitting projections 7a to 7f and the fitting projection fitting holes 7g which also constitute the comb tooth plate joining means, whereby the multiple comb of the first embodiment of the present invention is a product. Provided as An adhesive conforming to the characteristics of the synthetic resin material is attached to the fixing contact surface. Moreover, the plastic synthetic resin used as a raw material may have relatively poor elasticity when solidified.

According to the above configuration and the manufacturing method, the outer and outer comb teeth plates 1 and 2 and the inner comb tooth plate 3 are separate members, respectively. 3 (a) to 3 (c), and is taken out smoothly in the direction of the arrow as shown in FIGS.
As shown in the figure, when the product is manufactured, the exposed portion 13 of the inner side of the comb tooth comb is exposed between the fixed exposed portions of the outer side of the comb tooth plate 14 on the back side of the tooth comb. I do.

The exposed shape is such that, as shown in FIG. 2, the exposed portion 13 on the rear face of the comb teeth of the inner comb tooth plate and the exposed portions 14 on the back face of the comb teeth of the outer and outer comb teeth plates form the same curved surface. Alternatively, the inner-comb-plate comb-tooth-back exposed portion 13 may project from both outer-comb-plate comb-tooth-back back-exposed portions 14. This offers a wide range of design possibilities. In this embodiment, since the outer comb teeth plates 1 and 2 are made of a light-colored material and the inner comb tooth plates 3 are made of a dark-colored material, the contrast is sharp and the visual appeal is strong.

13 pieces 2 arranged on both outer comb teeth plates 1 and 2
Since there is a step between the long comb teeth 4a to 4n to 4n to z and the short comb teeth 10a to 10 of 14 rows arranged on the inner comb tooth plate 3, the long comb teeth 4a to 4m In addition, combing is easy because the density of the comb teeth on the comb surface formed by the tips of 4n to z becomes coarse.

Since the tips of the short comb teeth 10a to 10n are in contact with the hair surface or slightly fit into the hair, there is no difficulty in combing, and the comb is combed only with the long and short comb teeth only in the vicinity of the hair surface. Therefore, it is possible to perform the combing with a high combing density near the surface of the hair. If the combing is performed by gripping the gripping plate 12 extended to the comb tooth seat 8, the combing is also simple and effective.

Further, seven solid rod-shaped fitting projections 6a to 6f, 6g, which are means for joining the comb tooth plates, and a cylindrical bottomed fitting projection 7a to 7g are provided.
f, the interposition of the fitting projection fitting hole 7g enhances the degree of fixation of the three comb-tooth plates that are connected and fixed, and it is unlikely that a gap between the members at the time of combing occurs.

(Second Embodiment)

FIG. 4 is an exploded perspective view showing each member and the assembling procedure of the multiple comb according to the second embodiment of the present invention.

As shown in FIG. 4, in this embodiment, the present embodiment is composed of two outer comb-tooth plates 21 and 22 and a single inner comb-tooth plate 23 having a matching symmetrical shape. Solid bar-shaped fitting projections 24a to 24e and 24f projecting from the outer comb tooth plate 21 which is a means for connecting tooth plates, bottomed cylindrical fitting projections 25a to 25e projecting from the outer comb tooth plate 22 and the same. Fitting projection fitting holes 25f, fitting projection insertion holes 26a-e formed in the outer comb tooth plate 22, comb teeth seats 21a, 22a, 23a of the comb tooth plate.
Is almost the same as that of the first embodiment. However, in the present embodiment, a rod-shaped handle 23b is extended from the inner comb tooth plate 23.

Further, each comb tooth plate of this embodiment is made of a plastic synthetic resin, and a flowing resin flows into the cavity female mold.
By the manufacturing method in which the individual comb members are integrally formed as separate members and then connected and fixed via the connecting means, the finished product of this embodiment may be manufactured in the form shown in FIG. , And is the same as the first embodiment.

However, in the configuration of this embodiment, the first
The difference from the embodiment is that FIG. 6 is an end view of the embodiment.
, The outer comb teeth 27 arranged on the outer comb tooth plate,
28 is tapered in the outward direction, so to speak, is in the form of an open leg, and the surface formed by the tips of both outer comb teeth 21 and 22 and the tip of the inner comb tooth 28, that is, the combing surface, It is a curved surface that matches the shape of the skull surface.

The effect on design production realized by the above configuration and manufacturing method is almost the same as that of the first embodiment. However, as a characteristic effect of this embodiment, the width W of the tip surface of the comb tooth is wider than the width L of the comb tooth seat or the root of the comb tooth. Therefore, the comb area is wider than that of the conventional product or the first embodiment, in which both the comb tooth seat or the comb tooth root portion and the comb tooth tip face have the same width, and the abutment between the comb face and the skull. Inevitably, the combing efficiency from the surface layer of the hair to the deep part of the hair near the skull surface and the combing feeling at the time of combing become very good.

In this embodiment, at the manufacturing stage, the outer comb plates 21 and 22 and the inner comb plate 23 are formed separately from each other, and as a next process of this process, a parallel fixing process of these members is performed. However, since the step of extracting a plurality of side-by-side integrally formed comb teeth plates from the cavity, which has been used in the prior art, has been replaced, it is not necessary to match the extraction direction with the standing direction of the comb teeth, and when an elastic material is used. There is no need for so-called "forced removal" from the cavity. The removal of the outer comb tooth plate 21 from the cavity is performed smoothly in the direction of the arrow as shown in FIG. Therefore, no damage is caused to the member or the product due to “forced removal” when using a hard material having poor elasticity.

The second outer comb row 34 composed of the comb teeth 34a to 34i is slightly curved outwardly from a straight column, and has an open leg shape as in the second embodiment. Structurally, it can be said that the inner comb teeth plate of the second embodiment is removed and the double combs are connected and fixed via similar connecting means.

However, in this embodiment, since there are only two comb-tooth plates, in order to increase the combing efficiency, as shown in FIG. The first inner comb teeth 35a to 35h are located between the outer comb teeth rows 33 and 34 for both the tooth plates.
Of first inner comb teeth 35 and second inner comb teeth 36a to 36h
Is provided. Therefore, the total number of comb teeth is four. The comb teeth of these comb teeth rows are staggered at alternately standing points. The configuration in which the surface formed by the tips of the comb teeth, that is, the combed surface is adapted to the shape of the skull is the same as in the second embodiment.

With respect to these inner comb teeth, the first inner comb teeth 35 are formed integrally with the first comb teeth, and the second inner comb teeth 36 are formed integrally with the second comb teeth. Inner comb teeth 35a ~
i, 36a to 36i are substantially vertically suspended from the comb teeth seat 37.
For the cavities that make these two comb teeth,
This is as shown in FIG. 9 which is a sectional view thereof and FIG. 10 which is a partially transparent side view thereof.

The functions and effects of the above configuration and manufacturing method are the same as those of the second embodiment. The features of this embodiment are as follows.
