Description

[Technical Field]

[0001] The present invention relates to a comb. [Background technology]

[0002] Patent Document 1 discloses a conventional comb. This comb has a handle and a comb-tooth portion that is continuous with one end of the handle. The comb-tooth portion has a base and a plurality of comb teeth that are aligned in a row and extend in the same direction, with roots that are continuous with the base. In this comb, the thickness of the root of the comb tooth closest to the handle and the thickness in the vicinity thereof are approximately constant, and no ridge line is formed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Design Registration No. 1697299 Summary of the Invention [Problem to be solved by the invention]

[0004] When a user grips the handle of the comb in Patent Document 1, it is difficult to identify the position where the thumb or index finger should be placed. As a result, the user may not grip the comb in the appropriate position, which may result in poor operability.

[0005] The present invention has been made in consideration of the above-mentioned conventional situation, and an object to be achieved is to provide a comb that is easy for a user to grip at an appropriate position and is easy to operate. [Means for solving the problem]

[0006] The comb of the present invention comprises: The grip portion has a comb-tooth portion provided continuously at one end of the grip portion, The comb tooth portion is A base and a plurality of comb teeth whose roots are continuous with the base and which are aligned in the same direction; It has When viewed from a direction perpendicular to both the direction in which the comb teeth are arranged and the direction in which the comb teeth extend, a ridgeline extends from the handle portion to the base of the comb tooth located closest to the handle portion, on the side where the multiple comb teeth are arranged.

[0007] This comb is easy to grip by placing the thumb or index finger on the tip side of the comb teeth rather than the ridge line. Thus, the ridge line of this comb allows the user to intuitively grasp the position where to place the thumb or index finger, and the comb can be gripped in an appropriate position for easy operation. The "base of the comb teeth, on the side where multiple comb teeth are lined up" here refers to the side where multiple comb teeth are lined up, rather than the center in the direction in which the base of the comb teeth extends.

[0008] Therefore, the comb of the present invention is easy for the user to grip at an appropriate position and is easy to operate. [Brief explanation of the drawings]

[0010] A preferred embodiment of the present invention will now be described.

[0011] In the comb of the present invention, the base outer edge extending opposite the comb tooth side edge where the roots of the comb teeth of the base are continuous, and the handle outer edge of the handle extending continuous with the base outer edge, when viewed from a direction perpendicular to both the direction in which the comb teeth are arranged and the direction in which the comb teeth extend, may be curved so as to bulge in the direction opposite the direction in which the comb teeth extend. In this case, when the comb is held by a user, the handle outer edge fits comfortably in the palm of the user's hand. This makes the comb easy to grip and maneuver.

[0012] In the comb of the present invention, the thickness along the ridgeline may be thicker at the base of the tooth closest to the handle, where the plurality of teeth are aligned. In this case, when the comb is gripped by placing the thumb or index finger on the tip side of the tooth rather than the ridgeline, the thumb can easily apply pressure.

[0013] Next, Examples 1 and 2 embodying the comb of the present invention will be described with reference to the drawings. As shown in Figures 1 and 12, the comb 1, 101 of Examples 1 and 2 includes a handle portion 10, 110 and a comb-tooth portion 30, 130 provided continuously at one end of the handle portion 10, 110. The comb-tooth portion 30, 130 includes a base portion 31, 131 and a plurality of comb teeth 33, 133 whose root portions 33J, 133J are continuous with the base portion 31, 131 and which are aligned in a row and extend in the same direction.

[0014] 1 and 12, for ease of explanation, in a front view (hereinafter referred to as "front view") seen from a direction perpendicular to both the direction in which the comb teeth 33, 133 are lined up and the direction in which the comb teeth 33, 133 extend, the direction in which the comb teeth 33, 133 extend from the base 31, 131 is referred to as the downward direction, and the opposite direction is referred to as the upward direction. In a front view, the direction perpendicular to the direction in which the comb teeth 33, 133 extend, from the handle portion 10, 110 toward the comb tooth portion 30, 130, is referred to as the leftward direction, and the opposite direction is referred to as the rightward direction. In a front view, the near side is referred to as the front, and the opposite direction is referred to as the rear. In the three-dimensional Cartesian coordinate system shown in each figure, the positive direction of the X axis is the "left direction," the negative direction of the X axis is the "right 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."

[0015] Example 1 In the comb 1 of Example 1, as shown in FIGS. 1 to 5, the base 31 of the comb tooth portion 30 extends in the left-right direction. The upper edge 31U of the base 31 is curved so as to bulge upward in a front view. The upper edge 31U of the base 31 corresponds to the outer edge of the base. The lower edge 31L of the base 31 is curved so as to bulge upward in a front view. The lower edge 31L of the base 31 corresponds to the comb tooth side edge. In a front view, the curvature of the upper edge 31U of the base 31 is smaller than the curvature of the lower edge 31L. In a front view, the vertical width of the base 31 increases from the left end toward the right.

[0016] 8, the lower edge 31L of the base 31 has a lower surface 31B, a front inclined surface 31F, and a rear inclined surface 31P. The lower surface 31B of the lower edge 31L of the base 31 is strip-shaped and long in the left-right direction, and forms the front-to-rear center of the lower edge 31L of the base 31. In the front-to-rear cross section, the lower surface 31B of the lower edge 31L of the base 31 is a substantially flat surface with the front-to-rear center slightly lower.

[0017] The front inclined surface 31F of the lower edge 31L of the base 31 is continuous with the front end edge of the lower surface 31B and is inclined obliquely forward and upward. The front inclined surface 31F of the lower edge 31L of the base 31 forms the front surface of the lower edge 31L of the base 31. The rear inclined surface 31P of the lower edge 31L of the base 31 is continuous with the rear end edge of the lower surface 31B and is inclined obliquely backward and upward. The rear inclined surface 31P of the lower edge 31L of the base 31 forms the rear surface of the lower edge 31L of the base 31.

[0018] The intermediate comb teeth 33J of each intermediate comb tooth 36, which will be described later, are continuous with the lower portions of the front and rear inclined surfaces 31F and 31P of the lower edge 31L of the base 31, and with the lower surface 31B. The shape of the portion of the base 31 above the lower edge 31L is a substantially semi-elliptical shape in the front-to-rear cross section, with the upper edge 31U bulging upward. The front-to-rear cross section of the base 31 is symmetrical.

[0019] 2, 3, and 9, the thickness, which is the front-to-rear width of the base 31, gradually increases from the left-right intermediate portion to above the left end of the right-end comb tooth 35, which will be described later. The thickness of the base 31 is thickest above the left end of the right-end comb tooth 35. In other words, the thickness along the ridge line R, which will be described later, is thickest at the left end of the root 33J of the right-end comb tooth 35.

[0020] 1 and 9, the comb teeth 33 have one left-end comb tooth 34, one right-end comb tooth 35, and 25 intermediate comb teeth 36. The base 31, the one left-end comb tooth 34, the one right-end comb tooth 35, and the 25 intermediate comb teeth 36 are made of resin and are integrally molded.

[0021] The left-end comb tooth 34 is continuous with the left end of the base 31 and extends in the up-down direction. The left-end comb tooth 34 has a right side surface 34R, a front inclined surface 34F, a rear inclined surface 34P, and a left side surface 34L. As shown in FIG. 9, the right side surface 34R of the left-end comb tooth 34 is a substantially flat surface whose center in the front-to-rear direction in the horizontal cross section is located slightly toward the intermediate comb tooth 36 (to the right). The right side surface 34R of the left-end comb tooth 34 is continuous with the lower surface 31B of the lower edge portion 31L of the base 31.

[0022] The front inclined surface 34F of the left-end comb tooth 34 is continuous with the front edge of the right side surface 34R and is inclined obliquely forward toward the left. The front inclined surface 34F of the left-end comb tooth 34 forms the right front surface of the left-end comb tooth 34. The front inclined surface 34F of the left-end comb tooth 34 is continuous with the front inclined surface 31F of the lower edge portion 31L of the base 31.

[0023] The rear inclined surface 34P of the left-end comb tooth 34 is continuous with the rear edge of the right side surface 34R and is inclined obliquely rearward toward the left. The rear inclined surface 34P of the left-end comb tooth 34 forms the right rear surface of the left-end comb tooth 34. The rear inclined surface 34P of the left-end comb tooth 34 is continuous with the rear inclined surface 31P of the lower edge portion 31L of the base 31.

[0024] 9, the left side surface 34L of the left-end comb tooth 34 has a generally semicircular shape bulging leftward in horizontal cross section. The left side surface 34L of the left-end comb tooth 34 is continuous with a surface above the lower edge portion 31L of the base 31. As shown in FIGS. 1 and 4, the left-right width and front-to-back width of the left-end comb tooth 34 narrow downward.

[0025] As shown in FIGS. 1 and 9, the right-end comb tooth 35 is continuous with the right end of the base 31 and extends in the up-down direction. The right-end comb tooth 35 has a left side surface 35L, a front side surface 35F, and a rear side surface 35P. As shown in FIG. 9, the left side surface 35L of the right-end comb tooth 35 is a substantially flat surface whose center in the front-to-back direction is located slightly toward the intermediate comb tooth 36 (to the left) in a horizontal cross section. The left side surface 35L of the right-end comb tooth 35 is continuous with the lower surface 31B of the lower edge portion 31L of the base 31. The left side surface 35L of the right-end comb tooth 35 extends in the up-down direction. The extending direction of the left side surface 35L of the right-end comb tooth 35 is the same as the extending direction of each intermediate comb tooth 36. The left side surface 35L of the right-end comb tooth 35 narrows in the front-to-back width downward. As shown in FIG. 7, the lower end of the left side surface 35L of the right-end comb tooth 35 has an arc-shaped front-to-back cross section.

[0026] As shown in FIG. 9, the left edge of the front side surface 35F of the right-end comb tooth 35 is continuous with the front edge of the left side surface 35L. The left edge of the rear side surface 35P of the right-end comb tooth 35 is continuous with the rear edge of the left side surface 35L. The right edge of the front side surface 35F of the right-end comb tooth 35 and the right edge of the rear side surface 35P are continuous. As shown in FIG. 1, the right edges of the front side surface 35F and the rear side surface 35P of the right-end comb tooth 35 are inclined upward and rearward from the lower end of the left side surface 35L. As shown in FIG. 9, the thickness (front-to-rear width) of the right-end comb tooth 35 becomes thinner toward the right. In a front view, the root of the right-end comb tooth 35 is located near an imaginary straight line extending obliquely downward from the upper end of the left side surface 35L of the right-end comb tooth 35 to the upper ends of the right edges of the front side surface 35F and the rear side surface 35P of the right-end comb tooth 35.

[0027] As shown in Fig. 1, each of the intermediate comb teeth 36 is continuous with the lower edge 31L of the base 31 between the left-end comb tooth 34 and the right-end comb tooth 35, and extends straight and parallel in the vertical direction. The intermediate comb teeth 36 are arranged in a row at equal intervals. An imaginary curve connecting the tips of each of the intermediate comb teeth 36 curves slightly upward.

[0028] Each intermediate comb tooth 36 has a flat shape with a larger side surface area in left and right side views than in front view. As shown in FIG. 9, each intermediate comb tooth 36 has an elliptical shape that bulges outward left and right in horizontal cross section. As shown in FIGS. 1 and 9, each intermediate comb tooth 36 has a substantially constant left-right width from the root portion 33J continuing from the lower edge portion 31L of the base portion 31 to the tip (lower end portion). The tip portion of each intermediate comb tooth 36 has a substantially hemispherical shape. As shown in FIGS. 8 and 9, each intermediate comb tooth 36 has a tapered shape in which the front-to-back width gradually narrows from the root portion 33J to the tip. As seen in left and right side views, each intermediate comb tooth 36 has a substantially isosceles triangular shape with the tip portion as the apex angle. Each intermediate comb tooth 36 has a front-to-back symmetrical shape. Each intermediate comb tooth 36 with such a shape can reduce friction generated between the intermediate comb tooth 36 and hair when combing it. The comb teeth portion 30, which includes the base portion 31, the left-end comb teeth 34, the right-end comb teeth 35, and the intermediate comb teeth 36, is plated with a plating solution containing an antistatic agent. This allows the comb 1 to reduce the generation of static electricity when combing hair. The front-to-back width of each intermediate comb tooth 36 located rightward from the center of the comb teeth portion 30 gradually increases from the center to the right.

[0029] As shown in FIGS. 1 to 5, 10, and 11, the handle portion 10 includes a handle body 11, a weight 13, and a pair of covers 15 and 16. As shown in FIG. 11, the handle body 11 is continuous with the right end of the base 31 of the comb-tooth portion 30. The handle body 11 is made of resin and is integrally molded with the comb-tooth portion 30. The handle body 11 has recesses 11C on both the front and rear sides into which the covers 15 and 16 are fitted. The recesses 11C formed on both the front and rear sides of the handle body 11 are generally elliptical in shape in the direction in which the handle body 11 extends, as viewed from the front. The recesses 11C formed on both the front and rear sides of the handle body 11 are similar in shape to but slightly larger than the outer peripheries of the covers 15 and 16. The upper edge 11U of the handle body 11, which is continuous with the upper edge 31U of the base 31 of the comb-tooth portion 30, is curved to bulge upward, as viewed from the front. The upper edge 11U of the handle body 11 corresponds to the outer edge of the handle. Thus, in this comb 1, the outer edge of the base and the outer edge of the handle are curved to bulge upward when viewed from the front. As shown in FIG. 1, the upper edge 11U of the handle body 11 intersects with an imaginary line VL connecting the tip of the leftmost comb tooth 34 and the tip of the rightmost comb tooth 35. The angle α formed by the upper edge 11U of the handle body 11 and the imaginary line VL is greater than 90 degrees. Therefore, when using this comb 1, the handle portion 10 does not get in the way when combing hair. The thickness, which is the front-to-back width of the upper edge 11U of the handle body 11, gradually becomes thinner toward the right.

[0030] The handle body 11 has a storage section 12 that stores the weight 13 in a recess 11C on the back side. The weight 13 is a thin, rectangular parallelepiped that is long in one direction. The weight 13 is made of metal. The storage section 12 is a recess that stores the weight 13, which is a thin, rectangular parallelepiped that is long in one direction. The recess that is the storage section 12 is a rectangle that is long in the direction in which the handle body 11 extends, and is slightly larger than the outer diameter of the weight 13. The storage section 12 stores the weight 13 with its longitudinal direction aligned with the direction in which the handle body 11 extends. The weight 13 is glued to the storage section 12. The handle body 11 has a pair of through holes 11H that penetrate in the front-to-rear direction on both the left and right sides of the storage section 12 within the recesses 11C formed on both the front and rear surfaces.

[0031] The pair of covers 15, 16 are a front cover 15 and a rear cover 16. Each cover 15, 16 is made of resin. Each cover 15, 16 has a generally elliptical outer shape, and when attached to the handle body 11, the center portion is a curved surface that bulges outward. The front cover 15 has a pair of cylindrical portions 15A protruding from the rear surface at both left and right ends. When the front cover 15 is attached to the handle body 11, each cylindrical portion 15A is inserted into a respective through-hole 11H formed in the handle body 11. The front cover 15 is bonded to the handle body 11 around its outer periphery and around each cylindrical portion 15A. As shown in FIG. 10, the rear cover 16 has a pair of columnar portions 16A protruding from the front surface at both left and right ends. With the front and rear covers 15, 16 attached to the handle body 11, each columnar portion 16A is inserted into each cylindrical portion 15A of the front cover 15 inserted into each through-hole 11H of the handle body 11. The rear cover 16 is bonded to the handle body 11 around its outer circumferential edge and around each columnar portion 16A, and each columnar portion 16A is inserted into and bonded to each cylindrical portion 15A of the front cover 15. In this manner, each cover 15, 16 is bonded to the handle body 11.

[0032] The handle 10, to which the front and rear covers 15, 16 are attached, bulges out at the center so that the thickness, which is the front-to-back width, is greatest, as shown in Figures 2 to 5, 8, and 10. The handle 10 is thicker due to the attachment of the front and rear covers 15, 16, making it easier for the user to grip.

[0033] As shown in FIG. 1, in a front view of the comb 1, a ridgeline R extends from the upper edge 11U of the handle body 11 to the left side of the root 33J of the right-most comb tooth 35. The comb 1 also has a similar ridgeline R extending on the rear side. That is, as shown in FIGS. 6 to 8, the thickness of the comb 1 increases from the top to bottom toward the ridgeline R in the portion where the ridgeline R extends in the left-right direction. That is, the thickness of the comb 1 increases from the bottom of the right-most comb tooth 35 toward the ridgeline R. For this reason, the handle portion 10 of the comb 1 can be easily gripped by placing the thumb or index finger on the portion of the right-most comb tooth 35 that is closer to the bottom than the ridgeline R. The thickness (front-to-back width) of the comb 1 along the ridgeline R increases toward the left side of the root 33J of the right-most comb tooth 35, as shown in FIGS. 5 to 7 and 9.

[0034] <Example 2> The comb 101 of Example 2 differs from Example 1 in the shape of the handle portion 110 and the comb-tooth portion 130, and in that a weight 113 is provided at the right end of the handle portion 110. In the comb 101 of Example 2, as shown in FIGS. 12 to 16, the base 131 of the comb-tooth portion 130 extends in the left-right direction. The upper edge 131U of the base 131 is curved so as to bulge slightly upward in front view. The upper edge 131U of the base 131 corresponds to the outer edge of the base. The lower edge 131L of the base 131 is curved so as to bulge slightly upward in front view. The lower edge 131L of the base 131 corresponds to the comb-tooth side edge. In front view, the vertical width of the base 131 increases from the left end toward the right.

[0035] 20, the lower edge 131L of the base 131 has a lower surface 131B, a first front inclined surface 131Fa, a second front inclined surface 131Fb, a first rear inclined surface 131Pa, and a second rear inclined surface 131Pb. The lower surface 131B of the lower edge 131L of the base 131 is a strip-shaped flat surface that is long in the left-right direction and forms the front-to-rear center of the lower edge 131L of the base 131.

[0036] A first front inclined surface 131Fa of the lower edge portion 131L of the base 131 is continuous with the front end edge of the lower surface 131B and is inclined obliquely upward and forward. A second front inclined surface 131Fb is continuous with the upper end edge of the first front inclined surface 131Fa and is inclined obliquely upward and forward. The inclination angle of the second front inclined surface 131Fb with respect to the lower surface 131B is steeper than the inclination angle of the first front inclined surface 131Fa with respect to the lower surface 131B. The first front inclined surface 131Fa and the second front inclined surface 131Fb of the lower edge portion 131L of the base 131 form the front surface of the lower edge portion 131L of the base 131.

[0037] The first rear inclined surface 131Pa of the lower edge 131L of the base 131 is continuous with the rear end edge of the lower surface 131B and is inclined obliquely upward and rearward. The second rear inclined surface 131Pb is continuous with the upper end edge of the first rear inclined surface 131Pa and is inclined obliquely upward and rearward. The inclination angle of the second rear inclined surface 131Pb with respect to the lower surface 131B is steeper than the inclination angle of the first rear inclined surface 131Pa with respect to the lower surface 131B. The first rear inclined surface 131Pa and the second rear inclined surface 131Pb of the lower edge 131L of the base 131 form the rear surface of the lower edge 131L of the base 131.

[0038] A root portion 133J of each intermediate comb tooth 136, which will be described later, is continuous with the lower portions of the second front-rear inclined surfaces 131Fb, 131Pb of the lower edge portion 131L of the base portion 131, the first front-rear inclined surfaces 131Fa, 131Pa, and the lower surface 131B. The shape of the portion above the lower edge portion 131L of the base portion 131 is a substantially semi-elliptical shape in front-rear cross section, with the upper edge portion 131U bulging upward. The front-rear cross section of the base portion 131 is symmetrical front-rear.

[0039] 12 and 21, the comb teeth 133 have one left-end comb tooth 134, one right-end comb tooth 135, and 43 intermediate comb teeth 136. The base 131, the one left-end comb tooth 134, the one right-end comb tooth 135, and the 43 intermediate comb teeth 136 are made of resin and are integrally molded. The left-end comb tooth 134 is continuous with the left end of the base 131 and extends in the vertical direction.

[0040] The left-end comb tooth 134 has a right side surface 134R, a first front inclined surface 134Fa, a second front inclined surface 134Fb, a first rear inclined surface 134Pa, a second rear inclined surface 134Pb, and a left side surface 134L. As shown in Fig. 21 , the right side surface 134R of the left-end comb tooth 134 is flat. The right side surface 134R of the left-end comb tooth 134 is continuous with the lower surface 131B of the lower edge portion 131L of the base 131.

[0041] The first front inclined surface 134Fa of the left-end comb tooth 134 is continuous with the front edge of the right side surface 134R and is inclined obliquely forward toward the left. The second front inclined surface 134Fb is continuous with the front edge of the first front inclined surface 134Fa and is inclined obliquely forward toward the left. The inclination angle of the second front inclined surface 134Fb with respect to the right side surface 134R is steeper than the inclination angle of the first front inclined surface 134Fa with respect to the right side surface 134R. The first front inclined surface 134Fa and the second front inclined surface 134Fb of the left-end comb tooth 134 form the right front surface of the left-end comb tooth 134. The first front inclined surface 134Fa of the left-end comb tooth 134 is continuous with the first front inclined surface 131Fa of the lower edge portion 131L of the base 131. The second front inclined surface 134Fb of the left-end comb tooth 134 is continuous with the second front inclined surface 131Fb of the lower edge portion 131L of the base portion 131.

[0042] The first rear inclined surface 134Pa of the left-end comb tooth 134 is continuous with the rear end edge of the right side surface 134R and is inclined obliquely rearward toward the left.

The inclination angle of the second rear inclined surface 134Pb with respect to the right side surface 134R is steeper than the inclination angle of the first rear inclined surface 134Pa with respect to the right side surface 134R. The first rear inclined surface 134Pa and the second rear inclined surface 134Pb of the left-end comb tooth 134 form the right rear surface of the left-end comb tooth 134.

The left side surface 135L of the right-end comb tooth 135 extends in the vertical direction. The left side surface 135L of the right-end comb tooth 135 extends in the same direction as the respective intermediate comb teeth 136. The left side surface 135L of the right-end comb tooth 135 narrows slightly in front-to-rear width downward. As shown in FIGS. 16 to 19, the lower end of the left side surface 135L of the right-end comb tooth 135 has an arc shape that bulges downward.

[0045] As shown in FIG. 21 , the first front inclined surface 135Fa of the right-end comb tooth 135 is continuous with the front edge of the left side surface 135L and is inclined obliquely forward toward the right. The second front inclined surface 135Fb is continuous with the front edge of the first front inclined surface 135Fa and is inclined obliquely forward toward the right. The inclination angle of the second front inclined surface 135Fb with respect to the left side surface 135L is steeper than the inclination angle of the first front inclined surface 135Fa with respect to the left side surface 135L. The first front inclined surface 135Fa of the right-end comb tooth 135 is continuous with the first front inclined surface 131Fa of the lower edge portion 131L of the base 131. The second front inclined surface 135Fb of the right-end comb tooth 135 is continuous with the second front inclined surface 131Fb of the lower edge portion 131L of the base 131.

[0046] The first rear inclined surface 135Pa of the right-end comb tooth 135 is continuous with the rear end edge of the left side surface 135L and is inclined obliquely rearward toward the right. The second rear inclined surface 135Pb is continuous with the rear end edge of the first rear inclined surface 135Pa and is inclined obliquely rearward toward the right. The inclination angle of the second rear inclined surface 135Pb with respect to the left side surface 135L is steeper than the inclination angle of the first rear inclined surface 135Pa with respect to the left side surface 135L. The first rear inclined surface 135Pa of the right-end comb tooth 135 is continuous with the first rear inclined surface 131Pa of the lower edge portion 131L of the base 131. The second rear inclined surface 135Pb of the right-end comb tooth 135 is continuous with the second rear inclined surface 131Pb of the lower edge portion 131L of the base 131.

[0047] As shown in FIGS. 16 to 18 and 21, the front side surface 135Fc of the right-end comb tooth 135 is continuous with the front edge of the second front inclined surface 135Fb and inclined obliquely rearward toward the right. The rear side surface 135Pc of the right-end comb tooth 135 is continuous with the rear edge of the second rear inclined surface 135Pb and inclined obliquely rearward toward the right. The right side surface 135R of the right-end comb tooth 135 is continuous with the right edge of the front side surface 135Fc and the right edge of the rear side surface 135Pc and is a flat surface extending in the vertical direction. The root of the right-end comb tooth 135 is located near the left side surface 135L and an imaginary line extending slightly obliquely downward from the upper end of the first front inclined surface 135Fa toward the upper end of the front side surface 135Fc in a front view.

[0048] As shown in Fig. 12, each of the intermediate comb teeth 136 is continuous with the lower edge 131L of the base 131 between the left-end comb tooth 134 and the right-end comb tooth 135, and extends vertically in parallel. The intermediate comb teeth 136 are arranged in a row at equal intervals. The tips of the intermediate comb teeth 136 are arranged on an imaginary line connecting the tip of the left-end comb tooth 134 and the tip of the right-end comb tooth 135. The length of each of the intermediate comb teeth 136 gradually decreases toward the right.

[0049] Each intermediate comb tooth 136 has a flat shape with a larger side surface area in left and right side views than in front view. As shown in FIG. 21, each intermediate comb tooth 136 has an elliptical shape that bulges outward to the left and right in horizontal cross section. As shown in FIGS. 12 and 21, each intermediate comb tooth 136 has a slightly narrower left-right width from a root portion 133J continuing from the lower edge portion 131L of the base portion 131 toward the tip (lower end). The tip portion of each intermediate comb tooth 136 has an approximately hemispherical shape. As shown in FIGS. 20 and 21, each intermediate comb tooth 136 has a tapered shape in which the front-to-back width gradually narrows from the root portion 133J toward the tip. As seen in left and right side views, each intermediate comb tooth 136 has an approximately isosceles triangular shape with the tip as the apex angle. Each intermediate comb tooth 136 has a front-to-back symmetrical shape. Each intermediate comb tooth 136 with such a shape can reduce friction generated between the intermediate comb tooth 136 and hair when combing it. The comb teeth portion 130, which includes the base portion 131, the leftmost comb teeth 134, the rightmost comb teeth 135, and the middle comb teeth 136, and the handle portion 110, which will be described later, are plated with a plating solution containing an antistatic agent. Therefore, this comb 101 can reduce the generation of static electricity when combing hair.

[0050] As shown in Figs. 12 to 14, the handle portion 110 has a handle body 111 and a weight 113. The handle body 111 is continuous with the base 131 of the comb-tooth portion 130 and the right end of the right-most comb tooth 135, and extends rightward. The handle body 111 is made of resin and is molded integrally with the comb-tooth portion 130. The upper edge portion 131U of the base 131 of the comb-tooth portion 130 and the upper edge portion 111U of the handle body 111 of the handle portion 110 have a constricted portion 120 where the thickness (front-rear width) is reduced near the boundary between the base 131 and the handle body 111 and in the left-right central portion of the comb 101, as shown in Fig. 13.

[0051] As shown in Figures 12, 17, and 18, the handle body 111 has a lower surface 111B, a front inclined surface 111F, a rear inclined surface 111P, and an upper surface 111T. The lower surface 111B of the handle body 111 is a strip-shaped flat surface that is long in the left-right direction and forms the lower end surface of the handle body 111. The front inclined surface 111F of the handle body 111 is continuous with the front edge of the lower surface 111B and inclined obliquely forward and upward. The front inclined surface 111F of the handle body 111 forms the lower front surface of the handle body 111. The front inclined surface 111F of the handle body 111 is continuous with the front surface 135Fc of the right-end comb tooth 135. As shown in Figure 18, the front inclined surface 111F of the handle body 111 is flat from the front surface 135Fc of the right-end comb tooth 135 to the left-right center of the handle body 111. The front inclined surface 111F of the handle body 111 is a curved surface that bulges outward from the left-right central portion of the handle body 111 to the right end portion, as shown in FIG.

[0052] As shown in Figures 17 and 18, the rear inclined surface 111P of the handle body 111 is continuous with the rear edge of the lower surface 111B and is inclined obliquely upward and rearward. The rear inclined surface 111P of the handle body 111 forms the lower rear surface of the handle body 111. The rear inclined surface 111P of the handle body 111 is continuous with the rear side surface 135Pc of the right-end comb tooth 135. As shown in Figure 18, the rear inclined surface 111P of the handle body 111 is flat from the rear side surface 135Pc of the right-end comb tooth 135 to the left-right center of the handle body 111. The rear inclined surface 111P of the handle body 111 is a curved surface that bulges outward from the left-right center to the right end of the handle body 111, as shown in Figure 17.

[0053] The upper side surface 111T of the handle body 111 is continuous with the upper edge of the front inclined surface 111F and the upper edge of the rear inclined surface 111P, and has a generally semi-elliptical shape that bulges upward in front-to-back cross section. The boundary between the upper side surface 111T of the handle body 111 and the front inclined surface 111F and the boundary between the upper side surface 111T and the rear inclined surface 111P form a ridgeline R. The upper side surface 111T of the handle body 111 is continuous with the right end of the base 131 of the comb-tooth portion 130. The upper side surface 111T of the handle body 111 is curved so that the upper edge portion 111U extending in the left-right direction bulges slightly upward in front view. The upper edge portion 111U of the upper side surface 111T of the handle body 111 corresponds to the outer edge of the handle, and the upper edge portion 131U of the base 131 of the comb-tooth portion 130 corresponds to the outer extension of the base. In this way, in this comb 101, the base extension and the handle extension are curved so as to bulge slightly upward when viewed from the front.

[0054] The ridge line R formed on the handle body 111 is continuous with the ridge line R formed between the front and rear side surfaces 135Fc, 135Pc of the right-end comb tooth 135 and the base 131 of the comb-tooth portion 130. In other words, the ridge line R extends from the handle body 111 to the left side of the root portion 133J of the right-end comb tooth 135.

[0055] As shown in Figures 12 to 14, 16, and 22, the weight 113 is attached to the right end of the handle 110. The weight 113 is made of metal. The handle body 111 has a generally cylindrical protrusion 111A that protrudes rightward from the right end and has an outer diameter smaller than the outer diameter of the right end of the surface exposed as the handle 110. When attached to the right end of the handle 110, the weight 113 has a generally conical shape with its apex at the right end. The apex of this weight 113 is a curved surface. When attached to the right end of the handle 110, the weight 113 has a bottomed insertion hole 113A that extends rightward from the bottom surface. The weight 113 is bonded by inserting the protrusion 111A that protrudes rightward from the right end of the handle body 111 into the insertion hole 113A.

[0056] As described above, the comb 1,101 of Examples 1 and 2 comprises a handle portion 10,110 and a comb tooth portion 30,130 provided continuous to one end of the handle portion 10,110. The comb tooth portion 30,130 has a base portion 31,131 and a plurality of comb teeth 33,133 whose root portions 33J,133J are continuous with the base portion 31,131 and extend in the same direction side by side. When viewed from the front, a ridge line R extends from the handle portion 10,110 to the left side of the root portion 33J,133J of the right-end comb tooth 35,135 that is located closest to the handle portion 10,110.

[0057] The combs 1, 101 of Examples 1 and 2 make it easy to grip the handle 10, 110 by placing the thumb or index finger on the portion of the right-end comb tooth 35, 135 closer to the tip than the ridge line R. In this way, the ridge line R allows the user to intuitively know where to place the thumb or index finger on the comb 1, 101, and the comb can be gripped in an appropriate position for easy operation. Here, the left side of the base 33J, 133J of the right-end comb tooth 35, 135 refers to the area to the left of the center of the base of the right-end comb tooth 35, 135.

[0058] Therefore, the combs 1, 101 of Examples 1 and 2 are easy for the user to grip at an appropriate position and are easy to operate.

[0059] In the combs 1,101 of Examples 1 and 2, the upper edge 31U, 131U of the base 31, 131, to which the roots 33J, 133J of the comb teeth 33, 133 of the base 31, 131 are continuous, and the upper edge 11U, 111U of the handle body 11, 111 of the handle portion 10, 110, which extends continuously from the upper edge 31U, 131U of the base 31, 131, are curved to bulge upward in the opposite direction to the direction in which the comb teeth 33, 133 extend, when viewed from the front. Therefore, when the comb 1,101 of Examples 1 and 2 is held by a user, the upper edge 11U, 111U of the handle body 11, 111 fits comfortably in the palm of the user's hand. This makes the comb 1,101 easy to grip and maneuver.

[0060] In the comb 1 of Example 1, the thickness along the ridge line R increases toward the left side of the base 33J of the right-end comb tooth 35, 135, which is located closest to the handle 10. Therefore, the comb 1 of Example 1 can be easily gripped by placing the thumb or index finger on the part of the right-end comb tooth 35, 135 closer to the tip than the ridge line R.

[0061] The present invention is not limited to the first and second embodiments described above with reference to the drawings, and the following embodiments are also included within the technical scope of the present invention. (1) A metal reinforcing member may be inserted from the comb-tooth portion to the grip portion, which can improve the strength of the boundary between the comb-tooth portion and the grip portion. (2) Electrodes may be provided on the comb-tooth portion and the grip portion and electrically connected to the inserted metal reinforcing member. In this case, static electricity generated when combing hair can be eliminated. (3) The outer edge of the base and the outer edge of the handle do not have to be curved so as to bulge upward when viewed from the front. (4) The thickness along the ridge may be constant. (5) The shape of the intermediate comb teeth may be conical, cylindrical, or the like. The tip of each intermediate comb tooth may be spherical, with a diameter larger than that of the intermediate comb tooth. By making the tip of each intermediate comb tooth spherical, irritation to the scalp can be reduced. (6) The cover of the handle may be able to be adjusted to fit the shape of the user's hand.
