Barber tools

[0001] The present invention relates to a barber's tool.

[0002] Patent Document 1 discloses a hair styling tool, which is a conventional barber's tool. This hair styling tool includes a cover serving as a handle and a hair styling tool body. The cover has an arcuate bottom wall, a pair of side walls, and a support bracket. The arcuate bottom wall extends in one direction. The pair of side walls extend in the same direction from each of the opposite edges of the arcuate bottom wall. The support bracket extends in one direction between the pair of side walls at one end of the cover. The pair of side walls and the support bracket each have mounting holes formed on the same line. The hair styling tool body includes a comb and a brush. The comb has a shaft integrally molded on both sides of one end. The comb is positioned between one side wall of the cover and the support bracket. The comb shafts are inserted into mounting holes formed in one side wall and in the support bracket. The brush has a shaft integrally molded on both sides of one end. The brush is positioned between the other side wall of the cover and the support bracket. The brush shafts are inserted into mounting holes formed in the other side wall and the support bracket. The comb and brush rotate relatively around their respective shafts, transforming between a folded state and a usable state. This hair styling tool allows the user to use either the comb or the brush depending on the hair styling requirements.

[0003] Utility Model Registration No. 3106614

[0004] In the hair styling tool of Patent Document 1, the shanks of the comb and brush inserted into the attachment holes penetrating each side wall are exposed on the surface of each side wall of the cover. Also, with this hair styling tool, there is a risk that dirt or the like may get into the gap between the attachment holes penetrating each side wall and the shanks from the surface side of the cover. As a result, this hair styling tool has an unsightly appearance and the dirt may become more noticeable with use.

[0005] The present invention has been made in view of the above-mentioned conventional circumstances, and an object to be achieved is to provide a barber tool that looks good.

[0006] The hairdressing tool of the first invention is a hairdressing tool that comprises a handle and a hairdressing body and that can be transformed between a folded state and a usable state, wherein the handle comprises a wall portion extending in one direction and a pair of side walls extending in the same direction from each of the two side edges of the wall portion that extend in one direction, and the handle and the hairdressing body rotate relatively around a rotation axis located between the pair of side walls to transform between the folded state and the usable state, and both ends of the rotation axis are not exposed on the surface of each of the side walls.

[0007] In this barber's tool, both ends of the rotation shaft that rotates the handle and the main body relative to each other are not exposed on the surface of the side walls of the handle. Therefore, the rotation shaft cannot be seen from the surface of the handle. In other words, this barber's tool allows the handle and the main body to rotate relatively around the rotation shaft without forming recesses or gaps on the surface of the handle that could allow dirt and other contaminants to get in.

[0008] Therefore, the barber tool of the first invention has a good appearance.

[0009] The barber's tool of the second invention is a barber's tool comprising a handle and a barber's body, and a part of the outer edge of the handle has two mountain-shaped portions that bulge outward.

[0010] This barber tool can perform a pressure massage by pressing the user's skin using the outer edge of the mountain-shaped parts, or a so-called gua sha massage by sliding it over the user's skin using the outer edge of the valley part between the two side-by-side mountain-shaped parts.

[0011] Therefore, the barber tool of the second invention can be used for massaging the skin.

[0012] The hairdressing tools referred to here include combs, brushes, razors, mirrors, and makeup palettes. When the hairdressing tool is a comb, the hairdressing tool body is a comb body having multiple comb teeth. When the hairdressing tool is a brush, the hairdressing tool body is a brush body having multiple brush bristles. When the hairdressing tool is a razor, the hairdressing tool body is a razor body having a razor blade. When the hairdressing tool is a mirror, the hairdressing tool body is a mirror body having a mirror. When the hairdressing tool is a makeup palette, the hairdressing tool body is a palette body having a palette filled with cosmetics.

[0014] Preferred embodiments of the first and second inventions will be described.

[0015] In the barber's tool of the first invention, the barber's body may be a comb body having a plurality of comb teeth arranged in a row. In this case, the barber's tool is a comb. When the handle and the comb body are rotated relatively around the rotation axis to transform the comb into a folded state, the comb becomes compact and easy to carry. Therefore, the comb can be carried when traveling, and can be used by rotating the handle and the comb body relatively around the rotation axis to transform the comb into a usable state.

[0016] In the barber's tool of the first invention, the rotating shaft may be molded integrally with each of the side walls. In this case, the barber's tool can be connected by the rotating shaft while maintaining a constant distance between the side walls, thereby preventing deformation of the handle that would cause the distance between the side walls to increase.

[0017] In the barber's tool of the first aspect of the present invention, the barber's body may have a bearing through which the rotation shaft passes. In this case, the handle and the barber's body can be rotated relatively around the rotation shaft.

[0018] In the barber's tool of the second invention, the barber's body may be a comb body having a plurality of comb teeth arranged in a row. In this case, the barber's tool is a comb. This comb can be used to comb hair or to massage the skin using the angled portion of the handle.

[0019] In the second aspect of the present invention, the handle has a heart-shaped portion, and the two mountain-shaped portions may form part of the heart-shaped portion. In this case, the heart-shaped portion enhances the decorativeness of the barber's tool. In addition, the heart-shaped portion of the barber's tool is easy to grip.

[0020] In the barber's tool of the second invention, a portion of the outer edge of the handle may be curved and bulged outward to form a portion of the outer edge of the heart-shaped portion. In this case, the heart-shaped portion can enhance the decorativeness of the barber's tool.

[0021] In the barber's tool of the second invention, the handle and the barber's body can be rotated relative to each other to transform into a folded state, and the handle can cover at least a portion of the barber's body in the folded state. In this case, by transforming the barber's tool into the folded state and covering at least a portion of the barber's body, the barber's tool can be easily held for massage and carried around.

[0022] Example 1 Next, Example 1, which embodies a comb 1 as a barbering tool according to the first and second aspects of the present invention, will be described with reference to the drawings. As shown in FIGS. 1 to 4, 6, and 9, the comb 1 includes a handle 10 and a comb body 30. The handle 10 and the comb body 30 rotate relatively around a rotation shaft 50 to transform between a folded state and a use state. In the folded state, as shown in FIGS. 1 and 3, the handle 10 and the comb body 30 extend in the same direction from the rotation shaft 50 and overlap each other. In the use state, as shown in FIGS. 4 and 6, the handle 10 and the comb body 30 extend in opposite directions from the rotation shaft 50.

[0023] As shown in Figures 3, 6, and 7, the handle 10 has a wall portion 11, a pair of side walls 13, and a rotation shaft 50, and constitutes a grip portion 10A and a handle connecting portion 10B. The grip portion 10A is the portion that is gripped by the user when in use. The handle connecting portion 10B is continuous with the grip portion 10A and is provided at the rear end of the handle 10 opposite the tip end. The pair of side walls 13 form the rotation shaft 50 integrally at the handle connecting portion 10B.

[0024] As shown in Figures 1 to 6, 9, and 10, the comb body 30 has a base 31 and multiple comb teeth 33, and constitutes a comb section 30A and a comb connecting section 30B. The comb section 30A is a section in which multiple comb teeth 33 extending in the same direction from the base 31 are lined up in a row. The comb connecting section 30B is provided at the rear end of the base 31, opposite the tip section 31F. The base 31 has a bearing section 37 in the comb connecting section 30B, through which the rotary shaft 50 passes.

[0025] For ease of explanation, regardless of whether the comb body 30 is folded or in use, the direction in which each comb tooth 33 extends from the base 31 of the comb body 30 is referred to as the downward direction, and the opposite direction is referred to as the upward direction. The direction from the comb connecting portion 30B to the tip of the comb body 30 is referred to as the leftward direction, and the opposite direction is referred to as the rightward direction. The direction perpendicular to the up-down direction and the left-right direction is referred to as the front-rear direction. In the three-dimensional Cartesian coordinate system shown in each figure, the positive direction of the X axis is the "leftward direction," the negative direction of the X axis is the "rightward direction," the positive direction of the Y axis is the "upward direction," the negative direction of the Y axis is the "downward direction," the positive direction of the Z axis is the "forward direction," and the negative direction of the Z axis is the "rearward direction."

[0026] <Structure of the Handle 10> As shown in Figure 9, the wall 11 of the handle 10 has a predetermined width and extends long and substantially linearly in one direction (the left-right direction when the handle is in the folded state shown in Figures 1 and 3 and in the used state shown in Figures 4 and 6). The left-right dimension of the handle 10 is 126 mm, the up-down dimension is 21 mm, and the front-to-rear dimension is 10 mm. The wall 11 extends in the tangent direction of a circle centered on the rotation axis 50, which will be described later. As shown in Figures 3 and 6, the wall 11 extends from the tip of the handle 10 to partway along the handle connecting portion 10B. The surface 11F of the wall portion 11 (the lower surface in the folded state shown in Figures 1 to 3, and the upper surface in the used state shown in Figures 4, 6, and 7) bulges slightly outward (downward in the folded state shown in Figures 1 to 3, and upward in the used state shown in Figures 4, 6, and 7) in the front-to-rear direction perpendicular to the direction in which the wall portion 11 extends.

[0027] The rear end (the end on the handle connecting portion 10B side) of the wall portion 11 of the handle 10 is slightly inclined along the outer periphery of each side wall 13. That is, the rear end of the wall portion 11 is slightly inclined diagonally upward and to the right in the folded state, as shown in FIGS. 1 and 3 . The thickness of the wall portion 11 near its tip is greater than the thickness of the wall portion 11 extending further toward the rear end, as shown in FIGS. 3 and 6 . The lower end of the tip of the base 31 of the comb body 30 can come into contact with the back surface 11B (the upper surface in the folded state shown in FIG. 3 ) of the thickened portion of the wall portion 11 in the folded state. In this comb 1, the lower end of the tip 31F of the base 31 of the comb body 30 comes into contact with the back surface 11B of the wall portion 11 in the thickened portion, so that the tips of the comb teeth 33 of the comb body 30 do not come into contact with the back surface 11B of the wall portion 11 in the folded state.

[0028] As shown in Figures 1 and 3, the tip of the handle 10 protrudes distally beyond the tip of the comb body 30 (to the left in the folded state shown in Figures 1 and 3) in the folded state. The wall 11 protruding distally beyond the tip of the comb body 30 has a bulge 15 that bulges toward the comb body 30 in the folded state (upward in the folded state shown in Figures 1 and 3). The bulge 15 forms the tip of the handle 10. Because the tip of the handle 10 is configured with a curved surface, this comb 1 can effectively comb hair using the tip of the handle 10.

[0029] As shown in FIGS. 3 and 6 , the wall 11 of the handle 10 has a protruding wall 11T at its rear end that protrudes toward the comb body 30 (upward in the folded state shown in FIG. 3 and downward in the use state shown in FIG. 6 ). The protruding wall 11T protrudes approximately perpendicular to the wall 11. As shown in FIG. 3 , the tip of the protruding wall 11T is close to the tip of a first protrusion 35A of the comb body 30 (described later) when the handle 10 and the comb body 30 are in the folded state. When the handle 10 and the comb body 30 attempt to rotate relative to each other around the rotation axis 50 in the direction of transformation from the folded state to the use state, the tip ends of the protruding wall 11T and the first protrusion 35A come into contact with each other, preventing the rotation. In this way, the protruding wall 11T and the first protrusion 35A form a locking mechanism that locks the handle 10 and the comb body 30 in the folded state. When the handle 10 and the comb body 30 are rotated relative to each other about the central axis with a rotational force equal to or greater than a predetermined value, the tip of the protruding wall 11T and the tip of the first protrusion 35A pass over each other, enabling the comb body 30 to transform from the folded state to the use state. Furthermore, as shown in FIG. 6 , the tip of the protruding wall 11T is adjacent to the tip of the second protrusion 35B of the comb body 30 (described later) when the handle 10 and the comb body 30 are in the use state. When the handle 10 and the comb body 30 attempt to rotate relative to each other about the rotation axis 50 in the direction of transforming from the use state to the folded state, the tip of the protruding wall 11T and the second protrusion 35B come into contact with each other, preventing the rotation. In this way, the protruding wall 11T and the second protrusion 35B form a locking mechanism that locks the handle 10 and the comb body 30 in the use state. When the handle 10 and the comb body 30 are rotated relative to each other around the central axis with a rotational force greater than or equal to a predetermined value, the tip of the protruding wall 11T and the tip of the second convex portion 35B overcome each other, allowing the comb to be transformed from the use state to the folded state.

[0030] As shown in FIGS. 1 to 4 and 6 to 9 , the pair of side walls 13 of the handle 10 extend in the same direction (upward in the folded state shown in FIGS. 1 to 3 , downward in the used state shown in FIGS. 4 and 6 to 8 ) from each of the unidirectionally extending side edges of the wall portion 11. As shown in FIGS. 3 , 6 , and 8 , the pair of side walls 13 extend further toward the rear end of the handle 10 (to the right in the folded state shown in FIG. 3 , and to the left in the used state shown in FIGS. 6 and 8 ) than the rear end of the wall portion 11 where the protruding wall 11T is provided. The rear end of each side wall 13 (the right end in the folded state shown in FIGS. 1 and 3 , and the left end in the used state shown in FIG. 4 ) has a curved shape that protrudes in the opposite direction from the tip of the handle 10. The curved rear end of each side wall 13 makes it less likely to get caught on anything when carrying the comb 1 in the folded state, compared to a side wall with a sharp edge at the rear end. Therefore, the handle 10 and the comb body 30 of the comb 1 are unlikely to rotate unintentionally into the usable state.

[0031] The pair of side walls 13 constitute a handle connector 10B at their rear ends. The opposing inner surfaces 13B of the pair of side walls 13 are flat and extend parallel to each other at a predetermined distance in the handle connector 10B. As shown in FIG. 7 , the distance between the opposing inner surfaces 13B of the pair of side walls 13 in the handle connector 10B is slightly wider than the thickness of the comb connector 30B of the comb body 30 (described later). The surface 13F of each of the pair of side walls 13 in the handle connector 10B bulges slightly outward, forming a heart-shaped portion H that is heart-shaped in front and rear views. The outer edge of each of the pair of side walls 13 in the handle connector 10B has two outwardly bulging mountain-shaped portions 13M arranged side by side in front and rear views. The two mountain-shaped portions 13M arranged side by side on each of the pair of side walls 13 form part of the outer edge of the heart-shaped portion H. In front and rear views, the outwardly bulging curved portions of the rear end edges of the pair of side walls 13 are continuous with the rear end edges of the mountain-shaped portions 13M and form part of the outer edge of the heart-shaped portion H.

[0032] In each of the pair of side walls 13, the edge 13E (the upper edge in the folded state shown in FIG. 1 and the lower edge in the used state shown in FIGS. 4 and 6 ) extending away from the wall 11 gradually moves away from the wall 11 from the tip of the handle 10 toward the handle connector 10B. This makes it easy to grip the handle 10 when using the comb 1. The change in the vertical width of each side wall 13 is greater near the handle connector 10B than at the tip of the handle 10. In other words, the edge 13E of each side wall 13 extending away from the wall 11 is curved so as to be concave toward the wall 11, and the curvature is greater near the handle connector 10B at the rear end than at the tip of the handle 10.

[0033] The handle 10 comprises a grip portion 10A extending from the tip to the vicinity of the handle connecting portion 10B at the rear end. As shown in FIG. 2, the surfaces 13F of the pair of side walls 13 of the grip portion 10A are flat and extend parallel to each other. The opposing inner surfaces 13B of the pair of side walls 13 of the grip portion 10A are slightly larger than the width of the inserted comb teeth 33 in the front-to-rear direction. The opposing inner surfaces 13B of the pair of side walls 13 of the grip portion 10A gradually increase in width in the direction away from the wall portion 11 (upward in FIG. 2). Therefore, when the handle 10 and the comb body 30 are rotated relative to each other around the rotation axis 50 to transform into the folded state, the comb teeth 33 can be smoothly inserted between the pair of side walls 13 of the handle 10. In other words, when the handle 10 and the comb body 30 are rotated relative to each other around the rotation axis 50 and transformed into a folded state, the wall portion 11 of the handle 10 and the pair of side walls 13 come to cover the tip side of the comb teeth 33, which are part of the comb body 30.

[0034] 7, the rotating shaft 50 is integrally molded such that both ends are continuous with the inner surfaces 13B of the pair of side walls 13 of the handle connecting portion 10B. The rotating shaft 50 extends in a direction perpendicular to each of the inner surfaces 13B of the pair of side walls 13. The rotating shaft 50 is cylindrical.

[0035] <Structure of Comb Body 30> As shown in Figures 3, 6, 9, and 10, the comb body 30 has a horizontally elongated, flat plate shape that is long in the left-right direction and thin in the front-to-rear direction. The left-to-right dimension of the comb body is 116 mm, the up-to-down dimension is 27 mm, and the front-to-rear dimension of the upper edge is 3 mm. As shown in Figures 2 and 7, the front-to-rear thickness of the comb body 30 is thinner than the front-to-rear thickness of the handle 10. As shown in Figures 3, 6, 9, and 10, the base 31 of the comb body 30 includes an upper edge 31U, a tip 31F, and a rear 31B. The upper edge 31U extends linearly in the left-to-right direction. The tip 31F extends diagonally downward and left from the tip (left end) of the upper edge 31U. The rear 31B extends rearward and downward from the rear end of the upper edge 31U. A rear portion 31B of the base portion 31 of the comb body 30 constitutes a comb connecting portion 30B.

[0036] As shown in Figures 3, 6, 9, and 10, the upper surface of the upper edge 31U of the base 31 of the comb body 30 extends in the left-right direction. The upper surface of the upper edge 31U of the base 31 is a curved surface that bulges slightly upward in the front-to-rear direction (see Figure 2). The upper surface of the upper edge 31U of the base 31 is slightly inclined downward and left at the left end. The lower end of the upper edge 31U of the base 31 extends linearly in the left-to-right horizontal direction. As shown in Figure 2, the lower surface of the upper edge 31U of the base 31 includes a pair of inclined surfaces 31S that incline downward from the lower edges of the front and rear surfaces of the upper edge 31U of the base 31 toward the front-to-rear center, and a lower surface 31D that inclines slightly downward from the lower end of each inclined surface 31S toward the front-to-rear center.

[0037] The left surface of the tip 31F of the base 31 of the comb body 30 is continuous with the upper surface of the upper edge 31U of the base 31 (see FIG. 9). The left surface of the tip 31F of the base 31 is an inclined surface that slopes diagonally downward and leftward, as shown in FIGS. 1, 3, 4, 6, and 10. The left surface of the tip 31F of the base 31 is curved at the top so as to bulge diagonally upward and leftward. The right surface of the tip 31F of the base 31 is an inclined surface that slopes diagonally downward and leftward. The tip 31F of the base 31 has a width that gradually decreases in the left-to-right direction as it extends downward. The tip 31F of the base 31 has a width that gradually decreases in the front-to-back direction as it extends downward, as shown in FIGS. 2 and 9. The lower end of the tip 31F of the base 31 is located at the leftmost position on the comb body 30.

[0038] As shown in Figures 3, 6, and 8 to 10, the left end of the rear portion 31B of the base 31 of the comb body 30 is continuous at its upper part with the right end of the upper edge 31U. The left end of the rear portion 31B of the base 31, which extends downward from the lower end of the upper edge 31U, extends parallel to the rightmost comb tooth 33 extending in the vertical direction, with a predetermined gap between it and the rightmost comb tooth 33. The vertical length of the left end of the rear portion 31B, which extends downward from the lower end of the upper edge 31U of the base 31, is the same as the vertical length of the comb tooth 33.

[0039] The upper surface of the rear portion 31B of the base 31 of the comb body 30 is continuous with the upper surface of the upper edge portion 31U of the base 31. As shown in FIG. 7, the upper surface of the rear portion 31B of the base 31 is a curved surface that bulges slightly upward in the front-to-rear direction. As shown in FIGS. 3, 6, and 8 to 10, the upper surface of the rear portion 31B of the base 31 has an inclined surface 31K that slopes diagonally upward and to the upper right at the right end. The rear portion 31B of the base 31 has an upper rear end surface 31X that extends downward and continues from the right end of the inclined surface 31K. As shown in FIGS. 6 and 8, the upper rear end surface 31X comes into contact with the protruding wall 11T of the wall portion 11 of the handle 10 in the in-use state. Therefore, when the handle 10 is in the in-use state, it does not rotate counterclockwise around the rotation axis 50 relative to the comb body 30 in a front view.

[0040] As shown in Figures 3, 6, and 8 to 10, the right side surface and right lower surface of the rear portion 31B of the base 31 of the comb body 30 are continuous with the lower end of the upper rear end surface 31X and are curved surfaces that widen along an arc around the center of the bearing portion 37 (described later). The right lower surface of the rear portion 31B of the base 31 is continuous with the lower end of the right side surface. The right lower surface of the rear portion 31B of the base 31 has a first protrusion 35A near the left end that protrudes radially from the center of the bearing portion 37. The first protrusion 35A has a generally semi-cylindrical shape extending in the front-rear direction. The right side surface of the rear portion 31B of the base 31 has a second protrusion 35B near the upper end that protrudes radially from the center of the bearing portion 37. The second protrusion 35B has a generally semi-cylindrical shape extending in the front-rear direction.

[0041] The rear portion 31B of the base 31 of the comb body 30 forms a bearing portion 37 that penetrates in the front-rear direction. A rotary shaft 50 extending in the front-rear direction is disposed in the bearing portion 37. A passage 39 that connects an insertion opening 39I formed in the underside of the rear portion 31B of the base 31 to the bearing portion 37 penetrates in the front-rear direction through the rear portion 31B of the base 31. The width of the passage 39 is slightly larger than the diameter of the rotary shaft 50. The passage 39 includes a first passage 39A extending upward from the insertion opening 39I, a second passage 39B that extends diagonally upward and to the right from the upper end of the first passage 39A, and a third passage 39C that extends rightward from the upper end of the second passage 39B and connects to the bearing portion 37. A C-shaped pin 41 crosses the third passage 39C in the vertical direction at the boundary with the bearing portion 37.

[0042] As shown in FIGS. 3, 6, and 8, the rear portion 31B of the base 31 has a first through-hole 32A extending from the lower right surface to the lower surface of the third passage 39C, located to the right of the first protrusion 35A. The first through-hole 32A extends linearly in the vertical direction. The rear portion 31B of the base 31 also has a second through-hole 32B extending upward from the upper surface of the third passage 39C. The second through-hole 32B has a central axis aligned with the central axis of the first through-hole 32A. The upper portion of a C-shaped pin 41 inserted from the lower end of the first through-hole 32A passes through the third passage 39C and is inserted into the second through-hole 32B from the lower end thereof. The C-shaped pin 41, which crosses the third passage 39C in the vertical direction, prevents the rotating shaft 50 disposed in the bearing portion 37 from moving toward the third passage 39C. That is, the handle 10 and the comb body 30 are prevented from being separated by the C-shaped pin 41 that crosses the third passage 39C in the vertical direction.

[0043] As shown in FIGS. 3 , 6 , and 9 to 11 , the rear portion 31B of the base 31 of the comb body 30 has a groove 34 formed to the right of the bearing portion 37, into which a slippage adjustment spring 43 is fitted. The groove 34 opens to the front side of the rear portion 31B of the base 31. The groove 34 extends in the vertical direction. The spring 43 is disposed in the center of the groove 34, extending in the vertical direction. The groove 34 has alternating concave and convex portions facing the opposing surface on each of its left and right inner wall surfaces to prevent the spring 43 from protruding forward during assembly, etc. In other words, the left inner wall surface of the groove 34 is provided with a concave portion, a convex portion, a concave portion, and a convex portion in this order from top to bottom, while the right inner wall surface is provided with a convex portion, a concave portion, a convex portion, and a concave portion in this order from top to bottom.

[0044] 11, the spring 43 is formed by bending a spring wire so that both ends extend in the same straight line and the center portion protrudes in a mountain shape from both ends. The spring 43 is fitted into the groove 34 with both ends in contact with the bottom surface of the groove 34 and the center portion protruding beyond the front surface of the rear portion 31B of the base 31. The spring 43 fitted into the groove 34 is held within the groove 34 by being sandwiched from the left and right by multiple protrusions provided on the left and right inner wall surfaces of the groove 34.

[0045] The rotation shaft 50, which is integrally molded with the handle connecting portion 10B of the handle 10, is disposed in the bearing portion 37 of the comb body 30, and when the handle 10 and the comb body 30 are assembled, the center portion of the spring 43 fitted in the groove portion 34 contacts the inner surface 13B of the side wall 13 of the front handle connecting portion 10B. By having the center portion of the spring 43 contact the inner surface 13B of the side wall 13 of the handle 10, the rotation resistance of the handle 10 and the comb body 30 when rotated around the rotation shaft 50 can be adjusted appropriately.

[0046] As shown in Figures 1 to 6, 9, and 10, the multiple comb teeth 33 extend downward in parallel from the upper edge 31U and tip 31F of the base 31 of the comb body 30. The comb teeth 33 are aligned in a row in the left-right direction. In other words, the comb body 30 has multiple comb teeth 33 aligned in a row. The comb teeth 33 extending downward from the upper edge 31U of the base 31 have the same shape. The comb teeth 33 extending downward from the tip 31F of the base 31 gradually become shorter toward the tip (left). The comb teeth 33 have the same shape when projected from either the left or right direction.

[0047] Each comb tooth 33 has a flat shape with a side area viewed from either the left or right direction being larger than the side area viewed from either the front or back direction. As shown in FIG. 5, each comb tooth 33 has an outwardly bulging oval shape in horizontal cross section. As shown in FIG. 2, each comb tooth 33 has a tapered shape, with the front-to-back width gradually narrowing from the base, which is continuous with the upper edge 31U and tip 31F of the base 31, toward the tip. The tip of each comb tooth 33 has a curved surface. Each comb tooth 33 with this shape can reduce friction generated between the comb and hair when combing. The comb body 30 is plated with a plating solution containing an antistatic agent. This allows the comb 1 to reduce static electricity generation when combing hair.

[0048] <Assembly of the Handle 10 and the Comb Body 30> First, as shown in Figures 10 and 11, the spring 43 is fitted into the groove 34 formed in the rear portion 31B of the base 31 of the comb body 30. Next, as shown in Figures 3, 6, and 8, the rotating shaft 50, which is integrally molded with the handle connecting portion 10B of the handle 10, is placed in the bearing portion 37 through the insertion opening 39I formed in the rear portion 31B of the base 31 of the comb body 30, the first passage 39A, the second passage 39B, and the third passage 39C. Next, the C-shaped pin 41 is inserted into the first through hole 32A and the second through hole 32B formed in the rear portion 31B of the base 31 of the comb body 30. As a result, the rotating shaft 50 placed in the bearing portion 37 is prevented from moving toward the third passage 39C by the C-shaped pin 41 that crosses the third passage 39C in the vertical direction, and assembly of the handle 10 and the comb body 30 is completed.

[0049] Example 2 A second embodiment of a comb 101, which is a barber's tool according to the second invention, will be described with reference to the drawings. As shown in Figures 12 to 15, the comb 101 of Example 2 differs from the comb 1 of Example 1 in that the handle 110 and the comb body 130 are integrally formed and continuous, and the comb 101 does not change between the folded state and the usable state. Components identical to those of the comb 1 of Example 1 are designated by the same reference numerals, and detailed descriptions thereof will be omitted.

[0050] For ease of explanation, the direction in which each comb tooth 33 extends from the base 131 of the comb body 130 is referred to as the downward direction, and the opposite direction is referred to as the upward direction. The direction from the handle 110 to the tip of the comb body 130 is referred to as the leftward direction, and the opposite direction is referred to as the rightward direction. The direction perpendicular to the up-down direction and the left-right direction is referred to as the front-back direction. In the three-dimensional Cartesian coordinate system shown, the positive direction of the X axis is the "leftward direction," the negative direction of the X axis is the "rightward direction," the positive direction of the Y axis is the "upward direction," the negative direction of the Y axis is the "downward direction," the positive direction of the Z axis is the "forward direction," and the negative direction of the Z axis is the "backward direction."

[0051] <Structure of the Handle 110> The handle 110 is integral with the comb body 130. The handle 110 is continuous with the end of the comb body 130 opposite the tip (left end) of the comb body 130, which is elongated in the left-right direction. As shown in Figures 13 and 14, the handle 110 forms a heart-shaped portion H that is heart-shaped in front and rear views. The upper edge of the handle 110 has two upwardly bulging mountain-shaped portions 113M lined up in the left-right direction in the front and rear views. The two mountain-shaped portions 113M form part of the outer edge of the heart-shaped portion H. The curved portion of the rear end edge of the handle 110 that bulges outward continues to the rear end edge of the mountain-shaped portions 113M and forms part of the outer edge of the heart-shaped portion H. The front and rear surfaces of the heart-shaped portion H bulge slightly outward as shown in Figure 15. This makes it easy for the user to grip the heart-shaped portion H.

[0052] <Structure of Comb Body 130> As shown in Figures 12 to 15, the comb body 130 has a base 131 and multiple comb teeth 33. The comb body 130 has multiple comb teeth 33 arranged in a row, extending in the same direction from the base 131. The comb body 130 has an outer shape like a horizontally elongated flat plate that is long in the left-right direction and thin in the front-to-rear direction. The left-to-right dimension of the comb 101 is 144 mm. The up-to-down dimension of the comb body 130 is 34 mm, and the front-to-rear dimension of the upper edge 131U is 10 mm. As shown in Figure 15, the front-to-rear thickness of the comb body 130 is thinner than the front-to-rear thickness of the handle 110.

[0053] The base 131 of the comb body 130 includes an upper edge 131U, a tip 131F, and a rear 131B. The upper edge 131U extends linearly in the left-right direction. The upper surface of the upper edge 131U also extends in the left-right direction. The upper surface of the upper edge 131U is a curved surface that bulges slightly upward in the front-to-rear direction. The upper surface of the upper edge 131U is slightly inclined downward and left at the left end. The lower end of the upper edge 131U extends linearly in the left-to-right horizontal direction. The lower surface of the upper edge 131U includes a pair of inclined surfaces 131S that incline downward from the lower edges of the front and rear surfaces of the upper edge 131U toward the front-to-rear center, and a lower surface 131D that inclines slightly downward from the lower end of each inclined surface 131S toward the front-to-rear center.

[0054] The left surface of tip portion 131F is continuous with the upper surface of upper edge portion 131U. The left surface of tip portion 131F is an inclined surface that slopes diagonally downward and left. The left surface of tip portion 131F is curved so as to bulge slightly diagonally upward and left. The right surface of tip portion 131F is continuous with the lower surface of upper edge portion 131U. The right surface of tip portion 131F is an inclined surface that slopes diagonally downward and left. The right surface of tip portion 131F is curved so as to bulge slightly diagonally upward and left. The left-to-right width of tip portion 131F gradually decreases downward. The front-to-back width of tip portion 131F gradually decreases downward. The lower end of tip portion 131F is located at the leftmost position on comb body 130.

[0055] The left end of the rear portion 131B is continuous with the right end of the upper edge 131U. The upper surface of the rear portion 131B is continuous with the upper surface of the upper edge 131U. The upper surface of the rear portion 131B extends in the left-right direction. The upper surface of the rear portion 131B is a curved surface that bulges slightly upward in the front-to-rear direction. The right end of the upper surface of the rear portion 131B is continuous with the left end of the upper surface of the angled portion 113M of the handle 110. The left end of the lower end of the rear portion 131B is continuous with the right end of the lower end of the upper edge 131U. The lower end of the rear portion 131B extends while gradually curving downward toward the right.

[0056] The multiple comb teeth 33 extend downward in parallel from the upper edge 131U, the tip 131F, and the rear 131B of the base 131 of the comb body 130. The comb teeth 33 are aligned in a row in the left-right direction. In other words, the comb body 130 has multiple comb teeth 33 aligned in a row. The comb teeth 33 extending downward from the base 131 have the same shape. The comb teeth 33 extending downward from the tip 131F become gradually shorter toward the tip (left). The comb teeth 33 extending downward from the rear 131B become gradually shorter toward the right. The comb teeth 33 have the same shape when projected from either the left or right direction.

[0057] As described above, the barber tool of Example 1 is a comb 1 that has a handle 10 and a comb body 30 and that can be transformed between a folded state and a usable state. The handle 10 has a wall portion 11 that extends in one direction and a pair of side walls 13 that extend in the same direction from each of the two side edges of the wall portion 11 that extend in one direction. The handle 10 and the comb body 30 rotate relatively around a rotation shaft 50 that is located between the pair of side walls 13, and can be transformed between a folded state and a usable state. Both ends of the rotation shaft 50 are not exposed on the surface 13F of each side wall 13.

[0058] In the comb 1 of Example 1, both ends of the rotation shaft 50 that rotates the handle 10 and the comb body 30 relative to each other are not exposed on the surface 13F of each side wall 13 of the handle 10. Therefore, in this comb 1, the rotation shaft 50 cannot be seen from the surface 13F of the handle 10. In other words, this comb 1 allows the handle 10 and the comb body 30 to rotate relatively around the rotation shaft 50 without forming recesses or gaps on the surface 13F of the handle 10 that could allow dirt or other contaminants to get in.

[0059] Therefore, the comb 1 of Example 1 has a good appearance.

[0060] In the comb 1 of Example 1, the comb body 30 has a plurality of comb teeth 33 arranged in a row. Therefore, when the handle 10 and the comb body 30 are rotated relatively around the rotation shaft 50 to transform the comb 1 into a folded state, the comb 1 becomes compact and easy to carry. Therefore, the comb 1 can be carried when going out, and can be used by rotating the handle 10 and the comb body 30 relatively around the rotation shaft 50 to transform the comb 1 into a usable state.

[0061] In the comb 1 of Example 1, the rotating shaft 50 is molded integrally with each side wall 13. Therefore, the comb 1 can be connected by the rotating shaft 50 while maintaining a constant distance between the side walls 13, thereby preventing deformation of the handle 10 that would cause the distance between the side walls 13 to increase.

[0062] In the comb 1 of Example 1, the comb body 30 has a bearing portion 37 through which the rotation shaft 50 passes. Therefore, in this comb 1, the handle 10 and the comb body 30 can be rotated relatively around the rotation shaft 50.

[0063] The barber tools of Examples 1 and 2 are combs 1, 101 having a handle 10, 110 and a comb body 30, 130, and part of the outer edge of the handle 10, 110 has two outwardly bulging mountain-shaped portions 13M, 113M arranged side by side.

[0064] The combs 1, 101 of Examples 1 and 2 can perform a pressure massage by pressing the user's skin using the outer edges of the mountain-shaped portions 13M, 113M, or can perform a so-called gua sha massage by sliding the comb over the user's skin using the outer edges of the valley portions between the two adjacent mountain-shaped portions 13M, 113M.

[0065] Therefore, the combs 1 and 101 of Examples 1 and 2 can be used to massage the skin.

[0066] In the combs 1, 101 of Examples 1 and 2, the comb body 30, 130 has a plurality of comb teeth 33 arranged in a row. Therefore, with these combs 1, 101, the comb body 30, 130 can be used to comb hair, and the angled portions 13M, 113M of the handles 10, 110 can be used to massage the skin.

[0067] In the combs 1, 101 of Examples 1 and 2, the handles 10, 110 have a heart-shaped portion H, and the two mountain-shaped portions 13M, 113M form part of the heart-shaped portion H. Therefore, the combs 1, 101 can be made more decorative by the heart-shaped portion H. In addition, the combs 1, 101 are easy to grip by the heart-shaped portion H.

[0068] In the combs 1, 101 of Examples 1 and 2, a portion of the outer edge of the handle 10, 110 is curved and bulges outward to form a portion of the outer edge of the heart-shaped portion H. Therefore, the heart-shaped portion H can enhance the decorativeness of these combs 1, 101.

[0069] In the comb 1 of Example 1, the handle 10 and the comb body 30 can be rotated relative to each other to transform into a folded state, and in the folded state, the handle 10 covers a portion of the comb body 30. Therefore, by transforming the comb 1 into a folded state and covering a portion of the comb body 30, the comb 1 can be easily held for massage and can be easily carried.

[0070] The present invention is not limited to the first and second embodiments described above and illustrated in the drawings. The following embodiments, for example, are also within the scope of the present invention. (1) The rotating shaft does not have to be integrally molded with each side wall. In this case, recesses into which both ends of the rotating shaft can be inserted are formed on the inner surface of each side wall. This prevents the rotating shaft from being exposed on the surface of each side wall. (2) The device may be a hairdressing tool such as a brush, razor, mirror, or makeup palette. (3) A magnet may be placed on either the body or the handle, and a magnetic material such as metal may be placed on the other, thereby locking the body and handle in the folded and usable states. (4) The handle and the body may be detachable. In this case, the passageway connected to the bearing formed in the body may have a protruding portion at the boundary with the bearing, the passageway width being slightly narrower than the rotating shaft, allowing the rotating shaft to move over the protruding portion between the bearing and the passageway. In addition, the bearing portion of the container body may be provided with an elastically deformable C-shaped annular body that opens toward the passage, and the rotating shaft may be removably fitted into the C-shaped annular body. (5) A recess may be provided on one of the outer peripheral surface of the rotating shaft and the inner peripheral surface of the bearing portion, and a protrusion may be provided on the other, so that rotation of the handle can be stopped at a predetermined point between the folded state and the used state. (6) At least one of the handle and the container body may be made of aluminum oxide. In this case, the comb can have improved chemical resistance and durability compared to a comb made of resin. (7) The side wall of the handle may cover the container body. In this case, the container body can be protected from the outside. Also, only the upper edge of the container body may be exposed from the side wall of the handle. In this case, it is easy to rotate the handle and the container body around the rotating shaft.
