However, in the prior art as described above, for example, although a hair brush can set a hairstyle once, there is a problem that heat is not easily transmitted to the hair when the hair cannot be grasped well. Further, on the other hand, when the number of needles of the hair brush is excessively increased, the hair is tangled and does not fall off, which causes a large damage to the hair.

The present invention has been made in view of the problems described above, and an object thereof is to realize that hair is effectively grasped by the bristles and that the setting force of the hair is improved.

In order to solve the above-mentioned technical problem, the hair brush of the present invention includes a head portion and is disposed on a first surface setting portion of the head portion. The setting portion includes a plurality of bristles extending from a surface of the setting portion. The center of the cross-section of the bristles is geometrically disposed in the first surface, the geometrically configuration is an arrangement along a portion of a spiral in the first surface, and at least two of the plurality of bristles are aligned by The structure of the 1st bristles which consists of a hair heat transfer body.

According to one aspect of the present invention, the hair can be effectively grasped by the bristles, and the setting force of the hair can be improved.

FIG. 1 is a schematic view showing the arrangement schemes 100 and 110 of bristles of a conventional brush. In FIG. 1, the appearance of the brush is not shown, and the arrangement of the bristles viewed from a direction facing the brush surface (xy plane) (z-axis direction perpendicular to the xy plane) is schematically shown. As shown in FIG. 1 (a), in a general brush, the bristles 10 are arranged in a grid shape. In this configuration, hair friction is generated in a certain direction 101 in the xy plane. In other prior art, as shown in FIG. 1 (b), bristles 11 different from each other are arranged (Patent Document 1).

Patent Document 1 (Public Application No. 3206808) proposes a combination of a brush and an ion clip. In the bristles of Patent Document 1, it is not necessary to comb the hair once, and it is convenient to arrange the bristles (needle) in the xy plane in series opposite to the y axis (FIG. 3 (a)). Although this invention is used in a straight line, when such an array structure is used, the hair is rubbed in a certain direction 111 in the xy plane. Therefore, it is necessary to increase the number of bristles or to set the size of each bristle large. In Patent Document 1, there is almost no gap between the bristles and the bristles (FIG. 3 (a)), and the hair is considered to be damaged by strong friction.

In addition, Patent Document 2 proposes bristles that conform to the curvature of a human head, and it is also conceivable to design bristles based on this shape. However, although it is considered to have a suitable feeling for the head, for example, the part with long hair and separated from the head may feel worse in use. Although Patent Document 3 proposes a hair dryer that improves grip by animal hair, it cannot uniformly and efficiently transfer heat.

The need for a setting brush that increases the grip of the hair and efficiently transmits heat to the hair in a short time is expected.

[First embodiment]
Hereinafter, one embodiment of the present invention will be described in detail.

The hair brush of the present invention has a head for combing hair, and the head has a setting part for setting the hair. In a preferred embodiment, the setting portion is disposed on one side of the head. The head is composed of a thermal conductor that transmits heat to the hair, and has a plurality of needle shapes (bristles) standing upright (z-axis direction) with respect to the surface (xy plane) (bristle surface) of the setting portion.

FIG. 2 is a schematic view showing a geometrical arrangement of bristles of a bristle brush of the present invention. Figures 2 (a) to (c) do not show the appearance of the brush, but only schematically show the geometry of the bristles 20, 21, and 22 seen from the face of the brush (in the z-axis direction perpendicular to the xy plane).地 Configuration.

In a preferred embodiment of the present invention, the center of each of the xy planes of the needle-shaped bristles 20, 21, and 22 (see FIG. 3 (b) (i)) is arranged in a fixed geometric shape. . The preferred geometric shape is a two-dimensional curve, and more preferably a spiral (vortex). In a preferred embodiment of the present invention, it is characterized in that the bristles are arranged as part of a spiral along the xy plane.

Here, "a part of a spiral" refers to a part of a spiral included in a region constituting a setting portion in a conceptually expanded xy plane. It is preferable that the spiral consists of a plurality of spiral trajectories generated at a pitch of the xy plane constituting the setting section. For example, in FIG. 2 (a), it can be confirmed that at least 11 trajectories 202 of the spiral are generated in the xy plane coordinates constituting the setting section. In FIG. 2 (b), it can be confirmed that at least 11 helical trajectories 212 are generated in the xy plane coordinates constituting the setting section. In FIG. 2 (c), it can be confirmed that at least 12 spiral trajectories 222 are generated in the xy-plane coordinates constituting the setting section, and it can be confirmed that at least 16 spiral trajectories 223 are generated. The arrangement in which the bristles are arranged along a part of a spiral spiral in the xy plane is called a "spiral arrangement" or "spiral arrangement". The suspension scheme is not limited to an algebraic spiral such as Archimedes' spiral, and a logarithmic spiral can be used. In a preferred embodiment, a Fibonacci spiral can be used. Various parameters such as the initial radius and pitch of the spiral can be arbitrarily set.

In a preferred embodiment, an Archimedean spiral (algebraic spiral) that can be described with polar coordinates r = aθ can be used. For example, in the trajectory 223 of FIG. 2 (c), when the parameter a is 0.017 and θ = t × 360, 16 trajectories with t of 20 to 35 are generated. In the trajectory 223 of FIG. 2 (c), when the parameter a is 0.02 and θ = −t × 360, twelve trajectories of 36 to 47 are generated.

In the configuration of the present invention in which the xy plane bristles 20, 21, and 22 are arranged in a spiral shape, the metal needles (bristles) 20, 21, and 22 are evenly arranged. Thereby, the metal needles (bristles) 20, 21, 22 make sure contact with the hair to be rubbed independently of the position or direction 201, 211 of the hair entering (refer to FIG. 2 (a), (b)). As a result, the hair is caught by the metal needles (bristles) 20, 21, and 22, and the setting force of the hair can be improved.

As shown in FIGS. 2 (a) and 2 (b), the direction of the spiral may be the direction of the trajectory 202 or the direction of the trajectory 212. Further, as shown in FIG. 2 (c), it is preferable to arrange the bristles 22 at the intersections of the combinations of the trajectories 222 and 223 based on the spirals in two directions. Because the hair brush is used for the entire hair, it is assumed that the user of the right-handed person and the user of the left-handed person cannot determine the direction of the hair according to the use situation. With the configuration shown in FIG. 2 (c), hair entering from any direction will be caught by the bristles 22, and the setting force of the hair can be increased. The plurality of needles are configured to follow a first trajectory in one spiral, and the other plurality of needles may be configured to follow a second trajectory in the spiral (the second trajectory is adjacent to the first trajectory).

Fig. 3 shows a comparison of the arrangement of the bristles of the prior art and the present invention. FIG. 3 (a) schematically illustrates the interval of bristles of the prior art disclosed in Patent Document 1. FIG. The interval of the bristles in this invention is shown typically in FIG.3 (b). The satin shape of the xy plane of the bristles shown in FIG. 3 (b) is preferably an oval shape (see FIG. 4 (b) (i)). In FIG. 4 (b) (i), the axis parallel to the x-axis passing through the center is the long axis, and the axis parallel to the y-axis passing the center is the short axis. When the long axis and the short axis are equal (see FIG. 4 (b) (ii)), the cross-sectional shape of the bristles is circular. In the present specification, a circular shape is an aspect of an elliptical shape.

When bristling with a brush, the hair passes through the gap as much as possible. For example, in Patent Document 1 and the like, when the brush is moved in a specific direction (a direction opposite to 111), most of the hair may be wiped. In this case, the bristles 11 of the brush cannot grasp the hair, and because the hair interposed between the bristles 11 cannot transfer heat, the hair cannot be set to a desired shape. In Patent Document 1 for suppressing the brushing of hair, a method of increasing the density of the bristles 11 by a method of setting the thickness of the heat transfer needle to be thick, increasing the number of heat transfer needles, and the like is implemented. However, when the density of the metal bristles is increased indiscriminately, as shown in FIG. 3 (a), the gap in the y-axis direction of the bristles 31 (a) and 31 (b) becomes narrower, and as a result, the friction with the hair becomes smaller. Strong, causing damage to the hair, and the hair becomes difficult to enter between the needles.

In contrast, the gap in the y-axis direction between the bristles arranged spirally in the present invention does not become narrower than the gap in Patent Document 1. With this configuration, the hair can be set reliably while reducing the damage to the hair as compared with the conventional bristles.

In a preferred embodiment, it is characterized in that each center in the xy plane of the bristles 42 (see FIG. 4 (b) (ii)) is provided along a part of the spiral (see FIG. 4 (a)).

As shown in FIGS. 4A and 4C, the bristles 42 are preferably arranged along the y-axis direction at the ends in the short-side direction of the setting portion 40. In this configuration, the interval in the y-axis direction between the bristles at the ends in the short-side direction of the setting portion 40 can be shortened. Due to the nature of hair passing through the gap, with this configuration, it is possible to set a position where hair easily penetrates between the bristles.

Based on this configuration, the setting example can be improved by the spiral arrangement, and the ease of hair invasion can be improved, so that the effect balance can be improved.
