Description

Technical Field

[0001] The present invention relates to a folding comb having a surface subjected to a plating treatment. Background Art

[0002] When the surface of a comb is plated, it becomes smooth, reducing contact friction with the hair. Such a comb has the effect of discharging static electricity trapped in the hair by using the human body as a ground (see, for example, Patent Document 1). As shown in Patent Document 1, plating creates non-plated areas at the points of contact with the electrode. Plating can cause peeling starting from the non-plated areas, and during painting, hair dye, etc., can dissolve these non-plated areas, necessitating the use of plated components to cover them. In Patent Document 1, these non-plated areas are covered with interlocking covers. This plating treatment allows for smooth combing of hair and prevents tangles.

[0006] Problems to be solved by the invention

[0007] However, in Patent Document 1, the non-plated portion of the comb is covered from both sides with a cover. This requires two additional components, acting as covers, in addition to the comb body, increasing the number of components. Furthermore, in the case of a folding comb, even with a curved portion, the comb is thin, thus requiring improved operability.

[0008] The present invention has been made in consideration of the above-mentioned prior art, and an object of the present invention is to provide a folding comb that can efficiently cover non-plated portions to prevent plating peeling without increasing the number of parts, and can improve operability during use.

[0009] Means for solving problems

[0010] In order to achieve the above-mentioned purpose, the present invention provides a folding comb, which is characterized in that it comprises: a comb body having a plurality of comb teeth and having a plated portion and an unplated non-plated portion; a through hole formed by passing through the comb body; a rotating shaft inserted into the through hole; and a holding portion rotatably connected to the comb body via the rotating shaft, the non-plated portion being covered by the rotating shaft or the holding portion.

[0011] Preferably, the non-plated portion is formed on an inner wall surface of the through hole and contacts an outer wall surface of the rotating shaft.

[0012] Preferably, the grip portion includes a raised portion that bulges in the left-right direction around the rotation axis.

[0013] Preferably, the grip portion has a recessed portion that is recessed from a lower side toward an upper side.

[0014] Preferably, the comb body has a bulging portion that bulges out in the left-right direction at a position closer to the grip portion than the comb teeth.

[0015] Effects of the Invention

[0016] According to the present invention, since the non-plated portion is covered by the rotating shaft or the gripping portion, the non-plated portion can be covered and concealed using only the components required to form the folding comb. Consequently, there is no need to prepare separate components to cover the non-plated portion, which means the number of components does not increase, and the plating can be prevented from peeling off the non-plated portion. Furthermore, since the non-plated portion is covered, there is no need to intentionally avoid touching the non-plated portion when using the folding comb, thereby improving operability during use.

[0017] Furthermore, since the non-plated portion is formed on the inner wall surface of the through hole and contacts the outer wall surface of the rotating shaft, it is possible to prevent the non-plated portion from being exposed to the outside as much as possible. Even if plating peeling occurs, the possibility of the plating peeling and being exposed to the outside can be reduced.

[0018] Furthermore, by providing a raised portion on the grip, thickness can be increased around the rotating shaft. This improves rigidity in the area most susceptible to shaking and breakage, extending the life of the folding comb. Furthermore, this thickness makes it easier to grip and improves operability during use.

[0019] In addition, by providing a recessed portion in the gripping portion, the middle finger can be placed therein, thereby improving operability during use. In particular, this is effective because a thin folding comb is difficult to grip.

[0020] In addition, by providing the bulge portion on the comb body, the thumb and index finger can be placed thereon, and the position of the hand during use can be easily determined. Therefore, it is possible to start use smoothly and the operability during use can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Reference Figures 1 to 8 As can be seen, the folding comb 1 of the present invention comprises a comb body 2 and a grip 3. The comb body 2 has a plurality of comb teeth 4. The comb teeth 4 are used to comb the hair. Figure 4 As shown, the comb body 2 has a through-hole 5 extending horizontally through the comb body 2. The comb body 2 is plated, and this plated portion is referred to as the plated portion. On the other hand, the comb body 2 also has a non-plated portion. This non-plated portion is formed by the contact point with the electrode during the plating process. In the example shown, the non-plated portion is formed on the inner wall surface of the through-hole 5. It should be noted that plating can also be formed on the surface of the grip 3.

[0030] like Figure 5 As shown in FIG, the rotating shaft 6 is inserted into the through hole 5. Figure 6 As shown, the outer shape of the rotating shaft 6 is formed to follow the shape of the through-hole 5, with the portion of the shaft body that becomes a roughly cylindrical shape protruding. A hole is formed in the grip 3 to allow the insertion of the portion of the shaft body that becomes a roughly cylindrical shape, and the rotating shaft 6 is inserted into this hole. Therefore, the grip 3 is rotatably connected to the comb body 2 via the rotating shaft 6. In the folding comb 1 having such a structure, the non-plated portion is covered by the rotating shaft 6, regardless of whether the comb body 2 and grip 3 extend in a straight line in the so-called open state, or the grip 3 is rotated relative to the comb body 2 and folded in the so-called closed state.

[0031] Since the non-plated portion is covered by the rotating shaft 6, the non-plated portion can be concealed using only the components required to form the folding comb 1. Consequently, there's no need to prepare additional components to cover the non-plated portion, meaning the number of components doesn't increase, and plating peeling from the non-plated portion can be prevented. Furthermore, since the non-plated portion is covered, there's no need to intentionally avoid touching the non-plated portion when using the folding comb 1, improving ease of use. In particular, in the illustrated example, since the non-plated portion is formed on the inner wall of the through-hole 5 and in contact with the outer wall of the rotating shaft 6, exposure to the non-plated portion is minimized. Even if plating peeling occurs, the likelihood of it being exposed is minimized. Furthermore, since the non-plated portion is formed on the inner wall of the through-hole 5 and in contact with the outer wall of the rotating shaft 6, even when the folding comb 1 is opened or closed, the non-plated portion is protected from wear due to friction between the comb body 2 and the grip 3, preventing plating peeling from the non-plated portion.

[0032] It should be noted that the non-plated portion can be formed anywhere in the overlapping region 7, which is the portion where the grip 3 overlaps the comb body 2 when the grip 3 rotates. Even if a non-plated portion exists in the overlapping region 7, the grip 3 covers the non-plated portion, thereby achieving the same effect as described above. In this case, whether the folding comb 1 is in the open or closed state, if a non-plated portion exists in the overlapping region 7, which is the portion covered by the grip 3, the non-plated portion is always covered by the grip 3, which is preferable.

[0033] The grip 3 includes a raised portion 8 that protrudes in the left-right direction around the rotating shaft 6. Providing the raised portion 8 on the grip 3 creates thickness around the rotating shaft 6. This improves rigidity around the rotating shaft 6, a location most susceptible to shaking and potentially damaged, thereby extending the life of the folding comb 1. Furthermore, this thickness makes it easier to grip and improves operability during use.

[0034] The grip 3 has a recessed portion 9 that is recessed from the bottom toward the top. Providing the recessed portion 9 in the grip 3 allows the middle finger to rest there, improving operability during use. This is particularly effective because a thin folding comb 1 is difficult to grip.

[0035] The comb body 2 has a bulged portion 10 that bulges outward and horizontally, located closer to the grip 3 than the comb teeth 4. Providing the bulged portion 10 on the comb body 2 allows the thumb and index finger to rest on it, making it easier to position the hand during use. This allows for smoother initiation of use and improved operability.
