Description

The present invention relates to a hairbrush, particularly an electric hairbrush for setting hair.

However, in the above-mentioned conventional technique, for example, the hairbrush can set the hair at one time, but there is a problem that heat is not easily transferred to the hair unless the hair is caught well. On the other hand, if the number of brush pins is increased too much, the hair becomes entangled or cannot be pulled out, which causes a problem that the damage to the hair becomes large.

The present invention has been made in view of the above problems, and an object of the present invention is to realize that the hair is efficiently caught by a bristle and the hair setting force is enhanced.

In order to solve the above problems, the hair brush according to the present invention is a hair brush provided with a head portion, and a set portion composed of a heat transfer body that transfers heat to the hair is arranged on the first surface of the head portion. The set portion is provided with a plurality of bristle extending from the surface of the set portion, and the cross section perpendicular to the height direction of the bristle is an elliptical shape having a major axis and a minor axis, and the minor axis is , Arranged so as to have an angle rotated in one direction with respect to the longitudinal axis of the set portion, and the center of the cross section of the bristle on the first surface is geometrically arranged on the first surface. The geometrical arrangement is such that the arrangement is along a part of the spiral on the first surface.

According to the present invention, according to the above configuration, it is possible to bend the hair by utilizing the region of the ellipse having a large curvature.

According to one aspect of the present invention, the hair is efficiently caught by the bristle, and the setting force of the hair can be enhanced.

It is the schematic which shows the geometric arrangement of the bristle of the hairbrush which concerns on Embodiment 1. FIG. It is the schematic which shows typically the arrangement of the bristle of the hairbrush which concerns on Embodiment 2.

(A) is a side view of the hairbrush according to the sixth embodiment, and (b) is a perspective view of the hairbrush according to the sixth embodiment. 6 is a 6-view view of the hairbrush according to the sixth embodiment.

FIG. 1 shows a schematic view of the arrangement modes 100 and 110 of the bristle of the conventional hairbrush. Although the appearance of the hairbrush is not shown in FIG. 1, only the arrangement of the bristle viewed from the direction facing the brush surface (xy plane) (the z-axis direction perpendicular to the xy plane) is schematically shown. As shown in FIG. 1A, in a general hairbrush, bristle 10s are arranged in a grid pattern. In this structure, hair slips through in a certain direction 101 in the xy plane. In another prior art, as shown in FIG. 1 (b), the bristle 11s are arranged alternately (Patent Document 1).

Patent Document 1 (utility model No. 3206808) proposes a structure in which a brush and a hair iron are combined. The brush according to Patent Document 1 is convenient because it is not necessary to comb the hair once, but the arrangement of the bristles (pins) in the xy plane is in series with respect to the y-axis direction (FIG. 3 (a)). Although the device is for straight hair, if such an array structure is used, hair slips through in a certain direction 111 in the xy plane. Therefore, it is necessary to increase the number of bristle or set the size of each bristle to be large. In Patent Document 1, there is almost no gap between the bristle and the bristle (FIG. 3A), and it is considered that the hair is damaged by strong friction.

Further, Patent Document 2 proposes a bristle that matches the curvature of a human head, and it is conceivable to design a brush according to this shape. However, although it seems that the head has a fit, for example, in a part where the hair is long and away from the head, the feeling of use is rather deteriorated. Patent Document 3 proposes a dryer in which the grip force is improved by animal hair, but the heat cannot be transferred evenly and efficiently.

There is a need for a set hairbrush that can increase the grip of the hair and efficiently transfer heat to the hair in a short time.

[Embodiment 1]
Hereinafter, one embodiment of the present invention will be described in detail.

The hairbrush according to the present invention is a hairbrush having a head portion for combing hair, and the head portion has a set portion for setting hair. In a preferred embodiment, the set portion is arranged on one surface of the head portion. The set portion is composed of a heat transfer body that transfers heat to the hair, and has a plurality of pin shapes (bristles) that rise perpendicularly (z-axis direction) to the surface (xy plane) (brush surface) of the set portion.

FIG. 2 is a schematic view showing the geometric arrangement of the bristle of the hairbrush according to the present invention. 2 (a) to 2 (c) do not show the appearance of the hairbrush, but the geometric arrangement of the bristle 20, 21, 22 seen from the direction facing the brush surface (the z-axis direction perpendicular to the xy plane). Only is shown schematically.

In a preferred embodiment of the present invention, the centers of the pin-shaped bristles 20, 21, 22 in the xy plane (see FIGS. 3B and 3i) are arranged along a certain geometric shape. A preferred geometry is a two-dimensional curve, more preferably a spiral. As used herein, the term "spiral" refers to a spiral two-dimensional curve that moves away from the center as it turns. A preferred embodiment of the present invention is characterized in that a bristle is provided along a portion of the spiral in the xy plane.

Here, the "part of the spiral" means a part of the spiral included in the region constituting the set portion in the conceptually expanding xy plane. For the xy plane coordinates constituting the set portion, a spiral having a pitch such that a plurality of spiral tracks are generated is preferable. For example, in FIG. 2A, it can be confirmed that at least 11 spiral tracks 202 are generated at the xy plane coordinates constituting the set portion. In FIG. 2B, it can be confirmed that at least 11 spiral tracks 212 are generated at the xy plane coordinates constituting the set portion. In FIG. 2C, it can be confirmed that at least 12 spiral tracks 222 are generated and at least 16 spiral tracks 223 are generated at the xy plane coordinates constituting the set portion. The mode in which the bristles are arranged along a part of the spiral spiral on the xy plane is also referred to as "spiral arrangement" or "spiral arrangement". The mode of the spiral is not limited to an algebraic spiral such as Archimedes Spiral, and a logarithmic spiral or the like can be adopted. In a preferred embodiment, a Fibonacci spiral can be adopted. Various parameters such as the initial radius and pitch of the spiral can be set arbitrarily.

In a preferred embodiment, an Archimedes spiral (algebraic spiral) that can be described as r = aθ in polar coordinates can be adopted. For example, in the track 223 of FIG. 2C, when the parameter a is 0.017 and θ = t × 360, 16 tracks having t of 20 to 35 are generated. In the track 222 of FIG. 2C, when the parameter a is 0.02 and θ = −t × 360, 12 tracks having t of 36 to 47 are generated.

In the configuration according to the present invention in which the bristles 20, 21 and 22 are arranged in a spiral shape on the xy plane, the metal pins (bristles) 20, 21 and 22 are evenly arranged. As a result, the metal pins (bristle) 20, 21 and 22 are surely in contact with the hair to be slipped through, regardless of the place or direction 2011 and 211 in which the hair enters (FIGS. 2 (a) and 2 (b)). reference). As a result, the hair is caught by the metal pins (bristle) 20, 21, 22, and the setting force of the hair can be enhanced.

As shown in FIGS. 2A and 2B, the direction of the spiral may be the direction of the track 202 or the direction of the track 212. Further, as shown in FIG. 2C, it is also preferable to arrange the bristle 22 at the intersection of the spiral tracks 222 and 223 in the two directions. Since hairbrushes are used for the entire hair and are assumed to be right-handed users and left-handed users, the direction in which the hair progresses cannot be specified depending on the usage conditions. With the configuration shown in FIG. 2C, the bristle 22 catches the hair regardless of the direction in which the hair enters, and the setting force of the hair can be improved. The plurality of pins may be arranged along the first track in one spiral, and the other plurality of pins may be arranged along the second track in the spiral (the second track is adjacent to the first track).

In another preferred embodiment, the hairbrush comprises a grip portion and a head portion, and the head portion may be an elliptical column having a height in the major axis direction of the hairbrush. In the case of such an elliptical columnar head portion, it is preferable that the set portion is provided so as to be arranged on the surface of the elliptical columnar column.

As shown in FIG. 3, the cross-sectional shape of the bristle in the xy plane is preferably an elliptical shape (see FIGS. 3 (b) and 3 (i)). In FIGS. 3 (b) and 3 (i), the axis parallel to the x-axis passing through the center is the major axis, and the axis parallel to the y-axis passing through the center is the minor axis. When the major axis and the minor axis are equal (see FIGS. 3B and 3ii), the cross-sectional shape of the bristle is circular. In the present specification, the circular shape is one aspect of the elliptical shape.

When brushing with a hairbrush, the hair tries to pass through the gap as much as possible. For example, in Patent Document 1 and the like, when the hairbrush moves in a certain direction (opposite direction to 111), most of the hair may slip through. In such a situation, the bristle 11 of the hairbrush cannot catch the hair and cannot transfer heat to the hair through the bristle 11, so that the hair cannot be set in the desired style. In order to prevent hair from slipping through, Patent Document 1 takes measures such as setting the thickness of the heat transfer pins to be thicker and increasing the number of heat transfer pins to increase the density of the bristles 11. There is. However, if the density of the metal bristle is increased unnecessarily, the gap between the bristle in the y-axis direction becomes narrower. As a result, the friction with the hair becomes strong, the hair is damaged, and it becomes difficult for the hair to get between the pins.

On the other hand, the gap in the y-axis direction between the spirally arranged bristle according to the present invention is not narrowed like the gap in Patent Document 1. With such a configuration, it is possible to reliably set the hair while reducing damage to the hair as compared with the conventional arrangement of bristle.

In a preferred embodiment, the set portion 30 preferably includes two or more types of bristle having different cross-sectional areas. In a preferred embodiment, the cross-sectional shape of the bristle 32 in the xy plane is preferably circular. In a preferred embodiment, each center of the bristle 32 in the xy plane (see FIGS. 3B and ii) is provided along a portion of the spiral (see FIG. 3A).

As shown in FIGS. 3A and 3C, the bristle 32 is preferably arranged at the lateral end of the set portion 30 along the y-axis direction. In such a configuration, the distance between the bristles in the y-axis direction can be narrowed at the lateral end of the set portion 30. Since the hair has a property of trying to pass through the gap, such a configuration can provide a portion where the hair easily penetrates between the bristle.

With such a configuration, it is possible to improve the easiness of hair invasion and improve the balance of effects while improving the setting force by the spiral arrangement.
