Definitions

• the present invention relates to a folding comb whose surface is plated.
• Patent Document 1 the non-plated portions of the comb are covered with covers on both sides. This poses the problem of requiring two separate covers in addition to the comb body, which increases the number of parts. Furthermore, in the case of folding combs, the bent parts mean that they are inevitably thin, so there is also a need for improved operability.
• the present invention takes into consideration the above-mentioned conventional technology and aims to provide a folding comb that can efficiently cover non-plated areas without increasing the number of parts, preventing plating peeling, and also improves operability during use.
• the present invention provides a folding comb comprising a comb portion having a plurality of teeth and a plated portion and an unplated portion, a through-hole formed through the comb portion, a rotating shaft inserted into the through-hole, and a grip portion rotatably connected to the comb portion via the rotating shaft, wherein the unplated portion is covered by the rotating shaft or the grip portion.
• 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.
• the grip portion has a raised portion that rises in the left-right direction around the rotation axis.
• the grip portion has a recess formed by recessing from the bottom to the top.
• the comb portion has a bulging portion that bulges out in the left-right direction on the gripping portion side of the comb teeth.
• the non-plated portions are covered by the rotating shaft or gripping portion, so they can be covered and hidden using only the components necessary to form the folding comb. This means that there is no need to prepare additional parts to cover the non-plated portions, meaning that the number of parts is not increased and plating peeling from the non-plated portions can be prevented. Furthermore, because the non-plated portions are covered, there is no need to be careful not to touch the non-plated portions when using the folding comb, improving operability during use.
• the non-plated portion is formed on the inner wall surface of the through hole and is in contact with the outer wall surface of the rotating shaft, it is possible to minimize exposure of the non-plated portion to the outside, and even if the plating peels off, the possibility of it being exposed to the outside is reduced.
• thickness can be created around the rotation axis. This increases rigidity in the area most likely to wobble and break, extending the life of the folding comb. Creating such thickness also makes it easier to grip, improving operability during use.
• the middle finger can be placed there, improving operability during use. This is particularly effective as thin folding combs can be difficult to hold.
• the thumb and index finger can be placed there, making it easy to determine the position of the hand when using the device. This allows for smooth start-up and improves operability during use.

• the folding comb 1 comprises a comb portion 2 and a grip portion 3.
• the comb portion 2 has a plurality of comb teeth 4. These comb teeth 4 are used to comb hair.
• the comb portion 2 has through-holes 5 that penetrate the comb portion 2 in the left-right direction.
• the comb portion 2 is plated, and the plated portions form plated portions.
• the comb portion 2 also has non-plated portions that are not plated.
• the non-plated portions are formed at the contact points with the electrodes during the plating process. In the example shown, the non-plated portions are formed on the inner wall surfaces of the through-holes 5. Note that plating may also be formed on the surface of the grip portion 3.
• a rotating shaft 6 is inserted through the through hole 5.
• the outer shape of the rotating shaft 6 is formed to match the shape of the through hole 5, with a roughly cylindrical shaft body protruding from it.
• a hole is formed in the gripping portion 3 into which this roughly cylindrical shaft body can be inserted, and the rotating shaft 6 is fitted into this hole. Therefore, the gripping portion 3 is rotatably connected to the comb portion 2 via the rotating shaft 6.
• the non-plated portion is covered by the rotating shaft 6 whether the comb portion 2 and gripping portion 3 are in an open state in which they extend in a straight line, or whether the gripping portion 3 is in a closed state in which it is rotated and folded relative to the comb portion 2.
• the non-plated portions are covered by the rotating shaft 6, they can be covered and hidden using only the components necessary to form the folding comb 1. This eliminates the need for additional components to cover the non-plated portions, i.e., the number of components is not increased, and plating peeling from the non-plated portions can be prevented. Furthermore, because the non-plated portions are covered, there is no need to be careful not to touch the non-plated portions when using the folding comb 1, improving operability during use. In particular, in the illustrated example, the non-plated portions are formed on the inner wall surface of the through hole 5 and in contact with the outer wall surface of the rotating shaft 6, minimizing exposure of the non-plated portions to the outside. Even if plating peeling does occur, the likelihood of it being exposed to the outside is reduced.
• non-plated portions are formed on the inner wall surface of the through hole 5 and in contact with the outer wall surface of the rotating shaft 6, friction between the comb portion 2 and the grip portion 3 does not rub against the non-plated portions when the folding comb 1 is opened and closed, preventing plating peeling from the non-plated portions.
• the non-plated portion may be formed anywhere in the overlapping region 7, which is the portion that overlaps when the gripping portion 3 rotates relative to the comb portion 2. Even if there is a non-plated portion in this overlapping region 7, the non-plated portion will be covered by the gripping portion 3, and the same effect as described above can be obtained. In this case, it is preferable to have a non-plated portion in the overlapping region 7, which is the portion that is covered by the gripping portion 3, whether the folding comb 1 is open or closed, because the non-plated portion will always be covered by the gripping portion 3.
• the grip portion 3 has raised portions 8 that bulge left and right around the rotating shaft 6.
• the raised portions 8 on the grip portion 3 in this way, thickness can be created around the rotating shaft 6. This increases the rigidity around the rotating shaft 6, which is the area most likely to wobble and break, and helps to extend the life of the folding comb 1. Creating such thickness also makes it easier to grip, improving operability during use.
• the grip portion 3 has a recess 9 that is recessed from the bottom to the top. By providing this recess 9 on the grip portion 3, the middle finger can be placed there, improving operability during use. This is particularly effective as thin folding combs 1 can be difficult to hold.
• the comb portion 2 has a bulge 10 that bulges out in the left-right direction on the grip portion 3 side of the comb teeth 4.
• the thumb and index finger can be placed here, making it easy to position the hand during use. This allows for smooth start to use and improves operability during use.
