FIG. 1 is a schematic diagram showing arrangement plans 100 and 110 of the bristles of a conventional brush. In FIG. 1 , the appearance of the brush is not shown, but the arrangement of the bristles seen from the direction (the z-axis direction perpendicular to the xy plane) facing the brush surface (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, the rubbing of the hair occurs in a certain direction 101 in the xy plane. In another prior art, as shown in FIG.1(b), mutually different bristles 11 are arranged (patent document 1).

In Patent Document 1 (Utility Model No. 3206808 ), a combination brush and an ion clip are proposed. In the hairbrush of Patent Document 1, it is convenient to comb the hairs at one time, and the bristles (needles) are arranged in series with respect to the y-axis in the xy plane ( FIG. 3( a )). Although this invention is used in a straight line, when such an arrangement structure is adopted, the rubbing of the hair occurs in a certain direction 111 in the xy plane. Therefore, it is necessary to increase the number of bristles or set the size of each bristles to be large. In Patent Document 1, there is almost no gap between the bristles ( FIG. 3( a )), and the hair is considered to be damaged by strong friction.

Moreover, in patent document 2, the bristle which conforms to the curvature of a person's head is proposed, and it is also conceivable to design the bristle based on this shape. However, although it is considered that it has a suitable feeling for the head, for example, the part where the hair is long and separated from the head is not comfortable to use. Patent Document 3 proposes a hair dryer in which the grip strength is improved by animal hair, but it is not possible to transfer heat equally and efficiently.

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

[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 portion for setting hair. In a preferred embodiment, the setting portion is arranged on one side of the head. The head is composed of a heat conductor that transmits heat to the hair, and has a plurality of needle shapes (bristles) erected perpendicularly (z-axis direction) to the surface (xy plane) (brush surface) of the setting portion.

Fig. 2 is a schematic diagram showing the geometrical arrangement of the bristles of the 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 viewed from the surface facing the brush (in the z-axis direction perpendicular to the xy plane). ground configuration.

In a preferred embodiment of the present invention, the center of each of the needle-shaped bristles 20, 21, and 22 in the xy plane (refer to Fig. 3(b)(i)) is arranged in a fixed geometric shape . The preferred geometric shape is a two-dimensional curve, 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 helix along the xy plane.

Here, "a part of the spiral" refers to a part of the spiral included in the region constituting the setting portion in the conceptually expanded xy plane. Preferably, the spiral is formed by a plurality of trajectories of the spiral being generated at intervals of the xy plane constituting the setting portion. For example, in FIG. 2( a ), it can be confirmed that at least 11 spiral loci 202 are generated in the xy plane coordinates constituting the setting portion. In FIG. 2( b ), it can be confirmed that at least 11 spiral loci 212 are generated in the xy plane coordinates constituting the setting portion. In FIG. 2( c ), it can be confirmed that at least 12 spiral loci 222 are generated in the xy plane coordinates constituting the setting portion, and at least 16 spiral loci 223 can be confirmed to be generated. The configuration in which the bristles are arranged along a part of the spiral spiral in the xy plane is called "spiral arrangement" or "spiral arrangement". The solution of the suspension is not limited to an algebraic spiral such as an Archimedes spiral, and a logarithmic spiral or the like 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 Archimedes spiral (algebraic spiral) that can be described by 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 ranging from 20 to 35 are generated. In the trajectory 223 of Fig. 2(c), when the parameter a is 0.02 and θ=-t×360, 12 trajectories with t ranging from 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 equally arranged. Thereby, the metal needles (bristles) 20, 21, 22 surely contact the hair to be brushed without depending on the position or direction 201, 211 where the hair enters (see Figs. 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 ( b ), the direction of the spiral may be the direction of the track 202 or the direction of the track 212 . Moreover, as shown in FIG.2(c), it is preferable to arrange|position the bristles 22 at the intersection of the combination of the trajectories 222 and 223 based on the spiral of two directions. Since the brush is used for the entire hair, and it is assumed that a right-handed user and a left-handed user are used, the advancing direction of the hair cannot be determined according to the usage situation. In the configuration shown in FIG. 2( c ), the hairs are caught by the bristles 22 when they enter from any direction, and the setting force of the hairs can be increased. A plurality of needles are configured to follow a first trajectory in a spiral, and other plurality of needles may be configured to follow a second trajectory in the spiral (the second trajectory is adjacent to the first trajectory).

A comparison of the arrangement of the bristles of the prior art and the present invention is shown in FIG. 3 . In FIG.3(a), the space|interval of the brush bristles of the prior art disclosed in patent document 1 is shown typically. The interval of the bristles in the present invention is schematically shown 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 through 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 this specification, the circular shape is an aspect of an elliptical shape.

When brushing with a bristle brush, the hairs pass through the gaps as much as possible. For example, in Patent Document 1 and the like, when the brush moves in a specific direction (the direction opposite to 111 ), most of the hairs may be brushed off. In this case, the bristles 11 of the brush cannot hold the hair, and the hair cannot be set in a desired shape because the hair between the bristles 11 cannot transmit heat. In Patent Document 1 for suppressing the brushing of hair, the thickness of the heat transfer needles is set to be thick, and the correspondence of increasing the density of the bristles 11 is implemented by increasing the number of the heat transfer needles. However, when the density of the metal bristles is increased indiscriminately, as shown in FIG. 3( a ), the gaps in the y-axis direction of the bristles 31 ( a ) and 31 ( b ) are narrowed, and as a result, the friction with the hair is reduced. Strong, causing damage to the hair, it becomes difficult for the hair to get between the needles.

On the other hand, the gap in the y-axis direction between the spirally arranged bristles of the present invention does not become as narrow as the gap in Patent Document 1. With this configuration, compared with the conventional bristles, the damage to the hair can be reduced, and the hair can be set reliably.

As shown in FIGS. 4( a ) and ( c ), 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 the hair passing through the gap, with this configuration, it is possible to provide a position where the hair easily penetrates between the bristles.

With this configuration, the setting example is improved by the spiral arrangement, and the ease of hair penetration is improved, and the balance of the effects can be improved.

When the height of the bristles 41 (heat transfer needles) is low, hair tends to enter between the needles. If the cross-sectional area of the needle in the xy plane is also small, hair tends to enter between the needles. On the other hand, since the surface area of the heat transfer needle becomes an area that the hair can contact, the surface area of the heat transfer needle is preferably as large as possible.

In a preferred embodiment, the heights of the heat transfer needles (bristles 41 ) are preferably different for each of the spirally arranged tracks as shown in FIG. 8( a ). In the embodiment shown in FIG. 8( a ), the heights of the heat transfer needles (the bristles 41 ) are arranged so that a high trajectory and a low trajectory alternate.

Based on this configuration, the setting force can be increased by the spiral arrangement, and the contact area of the hair can be maintained at the same time, thereby improving the ease of hair penetration and improving the balance of the effect.
