JP-A-11-33072

  However, the above hair brush has the following drawbacks. That is, since the hair bristles 23 are fixed in close contact with the respective recesses 22, the hairs are easily caught between the bristles 23, and the hair that has been pinched and damaged easily becomes split ends. Moreover, if the brush hairs 23 are in close contact with the respective recesses 22, friction with the hair is large, and brushing cannot be performed unless strong force is applied. Moreover, since it is difficult for the hair to pass, the brush hair 23 hardly reaches the scalp, and the hair roots and pores cannot be cleaned cleanly.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a hair brush in which the hair is not easily pinched between the brush hairs, can be brushed with a small force, and the brush hair easily reaches the scalp. To do.

  In order to achieve the above object, the hairbrush of the present invention includes a grip portion and a brush base portion in which a large number of recesses are formed on the upper surface and the brush hairs are fixed to the respective recesses. A single bristle formed in an elongated shape and folded in a folded manner in each of the concave portions is disposed in a state where the bent portion is positioned and fixed in the concave portion, and a pair of bent pieces of the brush hairs. A configuration is adopted in which the members are held in a state where a predetermined gap is formed along the longitudinal direction of each of the recesses, and are standing upward.

  That is, in the hairbrush of the present invention, each recess formed on the upper surface of the brush base is formed in an elongated shape in plan view, and one brush hair bent in a double fold is formed in each recess. The part is disposed in a state where the part is positioned and fixed in the concave part. And a pair of bending pieces of each said bristle are hold | maintained in the state which opened the predetermined clearance gap along the longitudinal direction of each said recessed part, and each stands up. As described above, in the hairbrush of the present invention, one brush hair bent in a half-fold shape is held in a state where a predetermined gap is formed in each of the concave portions along the longitudinal direction, and the brush hairs are in close contact with each other. As a result, the hair does not get damaged by being pinched between the brush hairs. Moreover, there is little friction between the hair and the brush hair, and brushing can be performed with a small force. Moreover, since the hair easily passes, the brush hair can easily reach the scalp, and the hair roots and pores can be cleaned cleanly.

  Further, when the concave portion has an oval shape, an elongated concave portion in plan view can be easily obtained.

  Moreover, when the tip part of the pair of bent pieces is formed in a spherical shape, the spherical tip part softly contacts the scalp, and the massage effect is excellent.

  In addition, when one of the pair of bent pieces is set to have a longer standing length than the other, one of the pair of bent pieces comes into contact with the scalp while slightly curving, so that the spherical tip portion is attached to the scalp. Furthermore, it touches softly and is further superior in massage effect.

  In addition, a rod-like or plate-like fixing member having a predetermined thickness in the longitudinal direction is installed in a direction perpendicular to the longitudinal direction of each of the recesses in the lower part of each of the recesses. If it is disposed between the bent portions of one bent bristles, the gap between the pair of bent pieces can be adjusted by changing the thickness of each fixing member in the longitudinal direction.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  1 and 2 show an embodiment of the hairbrush of the present invention. In these figures, reference numeral 1 denotes a synthetic resin brush base portion in which a large number of recesses 2 (see FIGS. 3 and 4) are formed on the surface (upper surface) 1a, and brush hairs 3 are implanted in each of these recesses 2 (this In this embodiment, the brush base 1 is formed in a substantially rectangular shape that is long in the front-rear direction. The brush bristles 3 are formed by folding one brush bristle 3 (see FIG. 8) having spherical portions 3a at both ends in a folded shape, and one of a pair of bent pieces 3b formed by this folding. Is longer than the other (see FIGS. 9 and 10). In this embodiment, the longer bent piece 3b is fixed to each of the recesses 2 in a state where the longer bent piece 3b is positioned on the rear side of the shorter bent piece 3b. Further, a predetermined gap is provided in the front-rear direction between the bent pieces 3b. Reference numeral 4 denotes a synthetic resin handle (gripping portion) extending in series from the rear side of the brush base 1. Such a brush base 1 (the brush bristles 3 are not implanted in the respective recesses 2) and the handle 4 are integrally formed by molding.

  The brush base portion 1 has a curved surface (a curved surface that is curved in substantially the same shape on both the left and right sides) with its surface 1a gently curving from the central portion in the left-right direction toward both left and right side surfaces. As shown in FIG. 3 and FIG. 4, a group of recess rows in which 22 to 24 recesses 2 are arranged in a line at equal intervals in the front-rear direction is arranged on the surface 1 a in parallel at equal intervals on the left and right. There are 6 to 9 columns (in this embodiment, 8 columns, 4 columns on the right side and 4 columns on the left side). The left and right side surfaces of each recess 2 are formed so as to be inclined in a direction substantially orthogonal to the surface 1a of the brush base 1 (that is, slightly inward).

  As shown in FIGS. 5 to 7, each of the recesses 2 includes a central portion 11 having parallel left and right side surfaces, and both front and rear side portions formed in a semicircular arc shape in plan view on both front and rear sides of the central portion 11. 12 and 13 (front portion 12, rear portion 13), and is formed in an oval shape in plan view (elongated shape in plan view), and the longitudinal direction of each recess 2 is the longitudinal direction of brush base 1. Is arranged along the line. The bottom portion 11a of the central portion 11 is formed in a semicircular arc shape in cross section along the left-right direction (see FIG. 6), and the bottom portions 12a, 13a of the front and rear side portions 12, 13 are curved surfaces ( (Refer to FIG. 7).

  In the above configuration, first, a large number of brush hairs 3 (see FIG. 8, in which only one brush hair 3 is shown) having spherical portions 3 a formed at both ends, and a square having a predetermined front-rear width. A large number of aluminum fixing pieces 5 (see FIGS. 9 and 10) made of a rod-shaped body are prepared. Next, a single bristle 3 that is folded in half (both folded pieces 3b of the folded bristle 3 are folded so that one is longer than the other, and the longer is the rear side. In the state in which one fixing piece 5 is disposed between the bent portions 3c, it is press-fitted into the recess 2 and fixed (see FIGS. 9 and 10). The press-fitting and fixing are performed for each recess 2 or a plurality of recesses 2 at the same time, and one bent bristle 3 is implanted in all the recesses 2. In this state, the bent portion 3c of one bent bristle 3 is positioned on the bottom portions 11a, 12a, and 13a of the respective concave portions 2, and is caulked on both left and right side surfaces of the central portion 11 of the concave portion 2. It is fixed in a retaining shape by a fixing piece 5 fixed to (or in pressure contact). And both the bending pieces 3b of the bent one bristle 3 stand up from each said recessed part 2, and the predetermined clearance gap is provided in the front-back direction between both bending pieces 3b. (See FIG. 10).

  As described above, in this embodiment, the two folded pieces 3b of the single bristle 3 that is folded in half are held in the respective recesses 3 with a predetermined gap in front and rear. Therefore, the hair is not caught between the folded pieces 3b and is not damaged and becomes split ends. Moreover, there is little friction between the hair and each brush hair 3, and brushing can be performed with a small force. In addition, since the hair is easy to pass, the brush hair 3 can easily reach the scalp, and the hair roots and pores can be cleaned cleanly. Moreover, since the tip portions of the bent pieces 3b are formed in the spherical portion 3a, both the spherical portions 3a softly contact the scalp and have an excellent massage effect. Moreover, since one of the folded pieces 3b is formed longer than the other, the longer folded piece 3b abuts against the scalp while being slightly curved, so that the both spherical portions 3a further abut against the scalp. Excellent massage effect. In addition, by changing the front-rear width of the fixed piece 5, the gap between the bent pieces 3b can be adjusted.

  12 and 13 show a modification of the concave portion 2. In this example, a groove portion 15 extending in the front-rear direction and a tapered portion 16 inclined upward from the left and right side surfaces of the upper surface opening of the groove portion 15 are formed in the bottom portions 11a, 12a, and 13a of the recess portion 2. The bent portion 3c of the brush bristles 3 is disposed in the tapered portion 16, and the lower end portion of the bent portion 3 bites into the groove portion 15 (see FIG. 14). Other parts are the same as those of the recess 2 used in the above embodiment, and the same reference numerals are given to the same parts. Even when the concave portion 2 of this example is used, the same operation and effect as the above-described embodiment are obtained.

  15 to 17 show other modified examples of the recess 2. In this example, in the recess 2 shown in FIGS. 12 and 13, a circular recess 18 (on the upper cylindrical portion 18a and the left and right side surfaces of the lower end opening of the upper cylindrical portion 18a is formed inward from the upper surface of the recess 2. And a lower taper portion 18b inclined downward. Other parts are the same as those of the recess 2 shown in FIGS. 12 and 13, and the same parts are denoted by the same reference numerals. Even when the concave portion 2 of this example is used, the same operation and effect as the above-described embodiment are obtained. In addition, in this example, since the circular concave portion 18 is formed on the upper end surface of the concave portion 2, the concave portion of the hairbrush mold in which a circular concave portion in plan view is conventionally used is corrected. Therefore, it can be used as a mold for the hairbrush of the present invention.

  In the above embodiment, the longer bent piece 3b is positioned behind the shorter bent piece 3b. However, the present invention is not limited to this, and the longer bent piece 3b is shorter. It may be positioned on the front side of the bent piece 3b, and in each brush bristle 3, the arrangement of the two bent pieces 3b before and after may not be constant. Moreover, the length of these both bending pieces 3b may be the same. Moreover, the spherical part 3a may be formed only in the one end of the bristle 3, and the spherical part 3a does not need to be formed in both ends.

  Moreover, in the said embodiment, although the fixed piece 5 is comprised by the rod-shaped body, you may be comprised by the flat plate-shaped body. Moreover, the shape of the said recessed part 2 does not need to be formed in planar view oval shape, and what kind of shape may be sufficient if it is planar view elongate shape.
