[Patent Document 1] Japanese Patent Application Publication No. 2020-81854

[The technical problem that the invention is intended to solve]

In the above-mentioned comb, it is desired to achieve a variety of fit feelings.

The present invention is based on the above-mentioned situation, and its purpose is to provide a comb that can have a variety of fit. [Technical means]

The comb of the present invention has a plurality of first combing needles and a plurality of second combing needles protruding from the combing surface, and the curvature radius of the first imaginary line formed by the protruding ends of the plurality of first combing needles is different from the curvature radius of the second imaginary line formed by the protruding ends of the plurality of second combing needles. [Effect of the invention]

According to the present invention, since the shape of the protruding end of the first combing needle that is easy to fit with the scalp is different from the shape of the protruding end of the second combing needle that is easy to fit with the scalp, various fitting feelings can be achieved.

The following are ideal aspects of the present invention.

[1] The comb of the present invention has a plurality of first comb pins and a plurality of second comb pins protruding from the comb surface, and the radius of curvature of the first imaginary line formed by the protruding ends of the plurality of first comb pins is different from the radius of curvature of the second imaginary line formed by the protruding ends of the plurality of second comb pins. With this structure, the shape of the protruding ends of the first comb pins that is easy to fit the scalp is different from the shape of the protruding ends of the second comb pins that is easy to fit the scalp, so that a variety of fit feelings can be achieved. [2] In the comb described in [1] above, the protruding ends of the first comb pins are located further to the front end side of the protruding direction than the protruding ends of the second comb pins, and the first comb pins can be bent more easily than the second comb pins. With this structure, the first comb needle can be easily bent to match the shape of the part to be combed, and can easily fit the part. The second comb needle can easily hit the part to be combed, and can easily massage the part. Thus, a good fit can be achieved while also providing a suitable massage. [3] In the comb described in [1] or [2] above, the radius of curvature of the first imaginary line can be smaller than the radius of curvature of the second imaginary line. With this structure, the protruding end of the first comb needle can more easily fit the shape of the part to be combed than the protruding end of the second comb needle, and a good fit can be achieved. [4] In the comb described in any one of [1] to [3] above, the protruding end of the first comb needle is located further to the front end side of the protruding direction than the second comb needle, the first comb needle and the second comb needle are made of substantially the same material, and the first comb needle can be thinner than the second comb needle. In essence, as long as the effect of the invention can be achieved, even slight differences in components are considered the same. With this structure, the first comb needle is easy to bend to match the shape of the part to be combed, and is easy to fit the part. Since the second comb needle is easy to strongly touch the part to be combed, it is easy to massage the part. In this way, while the fit is good, appropriate massage can also be performed. [5] In the comb described in any one of [1] to [4] above, the comb surface has a convex portion and a concave portion, the length dimension of the first comb needle is the same as the length dimension of the second comb needle, the first comb needle can protrude from the convex portion, and the second comb needle can protrude from the concave portion. With this structure, the position of the protruding end of the first comb needle and the position of the protruding end of the second comb needle can be changed by using the first comb needle and the second comb needle of the same length dimension. [6] In the comb described in [5] above, the convex portion and the concave portion can be arranged alternately in a second direction orthogonal to the first direction while extending linearly in a first direction. With this structure, water can easily flow along the concave portion extending linearly, so that the comb surface can remove moisture well. According to this, the comb can be used hygienically. [7] In the comb described in any one of [1] to [6] above, the first comb needle and the second comb needle are arranged in the first direction and the second direction orthogonal to the first direction on the comb surface, and the central part of the first imaginary line and the second imaginary line extending in the first direction among the first imaginary line and the second imaginary line in the first direction may be more recessed to the rear side than the two end parts in the first direction. With such a structure, the protruding end of the first comb needle and the protruding end of the second comb needle can be easily attached to the human head. [8] In the comb described in any one of [1] to [7] above, the first comb needle and the second comb needle are arranged in the first direction and the second direction orthogonal to the first direction on the comb surface, and the central part of the first imaginary line and the second imaginary line extending in the second direction among the first imaginary line and the second imaginary line in the second direction may protrude further toward the front end side than the two end parts in the second direction. With such a structure, the protruding end of the first comb needle and the protruding end of the second comb needle can be easily attached to the back of a person's hair. [Example]

The second imaginary surface is curved in a spherical shape that is gentler than the first imaginary surface. The second imaginary surface includes all the second imaginary lines S2 and S4.

As shown in FIG. 4 , the comb 10 is formed by combining the first element 21, the second element 22, and the third element 23. The first element 21 forms the combing surface 11. The first element 21 integrally includes the combing surface 11, the first combing needles 12, and the second combing needles 13. The rear surface of the first element 21 presents the same concave-convex shape as the combing surface 11. Specifically, the rear surface of the first element 21 is formed with the same convex and concave portions as the combing surface 11.

The second element 22 is in the shape of a container with an open front side. The front side of the second element 22 is blocked by the first element 21. The inner sides of the second element 22 and the first element 21 are hollow. The third element 23 covers the entire outer surface of the second element 22. The outer surface of the third element 23 is formed with a design surface.

As shown in Figures 7 and 8, the comb 10 has a placement table 24. The placement table 24 has a base portion 25 and a frame portion 26. The base portion 25 and the frame portion 26 are formed as a whole. The bottom of the base portion 25 is horizontal. The frame portion 26 is shaped along the outer periphery of the grip portion 15. As shown by the arrow in Figure 7, the comb 10 is fitted into the frame portion 26 from the rear side. The frame portion 26 is locked to the outer periphery of the grip portion 15. When viewed from the left and right directions, the frame portion 26 stands up obliquely forward from the base portion 25. The upper end of the frame portion 26 is located further forward than the lower end of the frame portion 26. When the comb 10 is placed on the placement table 24, the comb surface 11 is maintained in a state of facing obliquely downward. When using the comb 10, the gripping portion 15 is grasped from the state shown in Fig. 8, and the comb 10 is picked up obliquely to the rear. Accordingly, the comb 10 is separated from the placement table 24 to be used for combing.

The comb 10 can be used when washing hair. In this case, water may penetrate into the inside of the comb 10. When the comb 10 is placed on the placement table 24, the water that has entered the inside of the comb 10 will flow down along the concave portion at the rear of the first element 21, and will be drained from the drainage holes 28 and 29 provided in the lower side area of the comb surface 11. At this time, since air can easily flow into the inside of the comb 10 from the drainage holes 27 provided on the left and right sides of the upper side area of the comb surface 11, the drainage function can be improved. In addition, the inside of the comb 10 and the outside of the comb 10 are connected by the plurality of drainage holes 27, 28, and 29, and the outside air can easily flow into the inside of the comb 10. Accordingly, the inside of the comb 10 can be easily dried.

The use example of the comb 10 related to the present embodiment is described. Grip the grip 15 and touch the comb 10 to the head. Initially, the protruding end 12E of the first comb needle 12 touches the head. The first comb needle 12 is elastically bent to match the shape of each user's head to fit the head. The comb 10 is further pressed against the head, and the protruding end 13E of the second comb needle 13 touches the head. At this time, because the curvature radius R2 of the second imaginary line S2 is larger than the curvature radius R1 of the first imaginary line S1, the protruding end 13E of the second comb needle 13 located at the two ends of the comb surface 11 in the up-down direction will not touch the head too strongly. On the other hand, the protruding end 13E of the second comb needle 13 located in the center of the comb surface 11 in the up-down direction can touch the head strongly. According to this, the scalp can be properly massaged. In addition, by properly moving the comb 10, the hair can be combed. Since the second combing needle 13 is not easy to bend, it can easily pass through the tangled hair. According to this, the hair can be properly combed.

Grip the grip 15 and bring the comb 10 into contact with the back hairline. When the comb 10 comes into contact with the back hairline, the comb 10 moves in the up-down direction toward the left-right direction of the back hairline. The first comb pin 12 is elastically bent in accordance with the shape of the back hairline to fit the back hairline. Further, the comb 10 is pressed hard against the back hairline, and the protruding end 13E of the second comb pin 13 comes into contact with the back hairline. At this time, the protruding ends 12E and 13E of the first comb pin 12 and the second comb pin 13 located at the left and right edges of the comb surface 11, in other words, the protruding ends 12E and 13E of the first comb pin 12 and the second comb pin 13 located at the upper and lower sides of the back hairline will retract, thereby preventing the comb 10 from coming into contact with the upper and lower sides of the back hairline too hard.

According to the embodiment constructed as described above, the following effects are achieved. The comb 10 has a plurality of first comb pins 12 and a plurality of second comb pins 13 protruding forward from the comb surface 11. The curvature radii R1 and R3 of the first imaginary line S1 formed by the protruding ends 12E of the plurality of first comb pins 12 are different from the curvature radii R2 and R4 of the second imaginary line S2 formed by the protruding ends 13E of the plurality of second comb pins 13. According to this structure, the shape of the protruding ends 12E of the first comb pins 12 that is easy to fit the scalp is different from the shape of the protruding ends 13E of the second comb pins 13 that is easy to fit the scalp, and various fitting feelings can be achieved.

In addition, the protruding end 12E of the first combing needle 12 is located further forward than the protruding end 13E of the second combing needle 13. The first combing needle 12 and the second combing needle 13 are made of the same material. The first combing needle 12 and the second combing needle 13 are formed, for example, by thermoplastic elastomer resin (TPE). The first combing needle 12 is thinner than the second combing needle 13, and the first combing needle 12 is easier to bend than the second combing needle 13. With this structure, the first combing needle 12 is easy to bend to match the shape of the target part to be combed, and it is easy to fit the target part. Because the second combing needle 13 is easy to strongly hit the target part to be combed, it is easy to massage the target part. According to this, while making the fit feel good, appropriate massage can also be performed. In addition, at the part of the combing surface 11 where the left-right dimension is the largest, the first combing pins 12 are arranged on both outer sides in the left-right direction compared to the second combing pins 13. With this configuration, when the combing surface 11 is moved in the left-right direction to comb the hair, the first combing pins 12, which are easy to bend, are more likely to contact the skin first than the second combing pins 13, which is less likely to cause discomfort to the user.

In addition, the combing surface 11 has a convex portion 17 and a concave portion 18. The length dimension L1 of the first combing needle 12 is the same as the length dimension L2 of the second combing needle 13. The first combing needle 12 protrudes forward from the convex portion 17. The second combing needle 13 protrudes forward from the concave portion 18. With this configuration, the position of the protruding end 12E of the first combing needle 12 and the position of the protruding end 13E of the second combing needle 13 can be changed by using the first combing needle 12 and the second combing needle 13 of the same length dimension.

In addition, the convex part 17 and the concave part 18 are respectively extended in the vertical direction in a straight line, and are alternately formed in the left and right directions perpendicular to the vertical direction. With this structure, water can easily flow along the concave part 18 extending in a straight line, so that the comb surface 11 can remove moisture well. According to this, the comb 10 can be used hygienically.

In addition, the first combing needle 12 and the second combing needle 13 are arranged in the vertical direction and the left-right direction of the combing surface 11. The central part of the vertical direction of the first imaginary line S1 and the second imaginary line S2 extending in the vertical direction is more recessed to the rear side than the two ends in the vertical direction. With this structure, the protruding end 12E of the first combing needle 12 and the protruding end 13E of the second combing needle 13 can be easily attached to the human head.

In addition, the left-right central portion of the first imaginary line S3 and the second imaginary line S4 extending in the left-right direction protrudes further forward than the left-right end portions.
