Description

  The present invention relates to a brush.

  Barbers and hairdressers (hereinafter referred to as barbers and hairdressers) often use hair styling to shave their hair. For this reason, if oil is on the fingers, the brush becomes slippery and may fall off when styling the hair using a brush.

  For the purpose of preventing slipping, for example, Patent Document 1 discloses a brush having a grip portion in which a plurality of anti-slip holes are opened. However, by simply opening the anti-slip hole in the gripping part, the sliding effect is limited only in the palm where the anti-slip hole hits when the gripping part is gripped, and the compression is repeated only in that part. For this reason, the keratin on the skin surface becomes hard and thick for a long time, and there is a possibility that the portion becomes octopus in some cases.

  Moreover, an anti-slip effect cannot be obtained unless the gripping portion is conscious of a specific portion where the anti-slip hole is formed. For this reason, in order to acquire the said effect, it will be necessary to change a holding part. Therefore, workability is reduced accordingly.

And there are cases where delicate brushing work such as gripping the brush very lightly or working with a dominant index book, the curvature of the fingertip and the surface shape of the gripping part fit exactly well. If not, you could drop the brush during work.
Japanese Utility Model Publication No. 7-39569

The present invention has been made in view of such circumstances, and problems to be solved are as follows.
The object of the present invention is to provide a brush excellent in the sense that the brush fits firmly on the palm and fingertips even if the grip part is extremely lightly gripped or the grip part is held with a dominant index book.

  Therefore, the present invention employs the following means in order to solve the above problems.

  That is, the brush of the present invention is a brush having a flocked portion having brush hairs for brushing and a gripping portion integrated with the flocked portion, and a three-dimensional uneven portion on the outer peripheral surface of the gripping portion. The three-dimensional concavo-convex part has a plurality of unit surfaces, a boundary ridge line defining the unit surface, and an intersection point formed by the boundary ridge lines intersecting, and the boundary ridge line and the intersection part. Is positioned relatively outward from the axis of the gripper with respect to the unit surface, and the unit surface has a concave curved surface shape that is smoothly recessed between the opposing intersections, and is adjacent in the circumferential direction of the gripper It is characterized by being relatively displaced in the axial direction of the grip portion in comparison with the unit surface.

  Therefore, according to the brush of the present invention, since the three-dimensional uneven portion is formed on the outer surface of the grip portion, the brush is picked up in comparison with a brush having no such three-dimensional uneven portion in the grip portion. Sometimes, the degree of close contact between the grip surface and the palm or fingertip is high. For this reason, when the hairdressing and beautician grips the gripping part of the brush or holds it with a dominant finger, not only is the fitting feeling transmitted from the gripping part excellent, but the brush is difficult to separate from the palm and fingertip.

  It is preferable that the radius of curvature of the recess of the unit surface is the radius of curvature of a finger ball having an average palm size.

  You may make it integrate the said hair transplant part and the said holding part by a screwing means.

  When the brush is temporarily not used, it is convenient that the holding portion is formed with a locking portion that is hooked on the belt of the user's pants or the upper edge of the waist portion.

According to the brush of the present invention, since the fit is high and the brush is difficult to be separated from the palm and fingertips, a delicate feel is transmitted to the hairdressing and beautician through the brush when performing a delicate brushing operation.
Therefore, even in the case of a person with a delicate hair quality, brushing can be performed with the optimum method of using the person.
In addition, it is hard to fall even if you hold the brush lightly.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of a brush according to the invention will be described with reference to the drawings.

A first embodiment will be described with reference to FIGS.
A roll brush (hereinafter referred to as a brush) 1 which is one of the brushes is made of, for example, a synthetic resin or wood, and includes a flocked portion 20 and a gripping portion which is integrally formed with the flocked portion 20 and is formed in a coaxial rod shape. 30.

  The flocked portion 20 has a polygonal shape (multi-sided shape) in cross-sectional shape (see, for example, FIGS. 1 and 8). In this embodiment, a regular hexagon is shown. A large number of hairs are planted on the hair planting surface 22.

The grip portion 30 has a three-dimensional uneven portion 40 in almost the entire outer peripheral surface except for both ends thereof.
In addition, at the lower end of the grip 30, that is, the end located on the opposite side in the axial direction of the brush 1 to the flocked portion 20, the belt of the trouser when the hairdressing and beautician does not use the brush 1 temporarily Further, a locking portion 32 that is hooked on the upper edge of the waist portion is integrally formed (see FIG. 12). The locking portion 32 is shaped like a question mark “?” In the longitudinal section.

  As can be seen from FIGS. 1, 2, 5, 10, and the like, the three-dimensional concavo-convex portion 40 includes unit surfaces 50, boundary ridge lines 60 that define a large number of unit surfaces 50, and boundary ridge lines 60 intersect each other. It is a three-dimensional concavo-convex part having a crossing point part 70 formed as a constituent element. The crossing point portion 70 is a portion where the boundary ridge lines 60 cross each other linearly. The boundary ridge line 60 appears to meander and extend in the axial (longitudinal) direction of the gripping portion 30 (the axial direction of the brush).

  In short, the three-dimensional concavo-convex portion 40 is formed by combining a large number of substantially quadrangular unit surfaces 50 connecting the apexes a, b, c, and d as shown in FIG. In this embodiment, the quadrangular shape of the unit surface 50 has a long rhombus shape in the axial direction as shown in FIGS. The unit surface 50 is adjacent to the other unit surface 50 via the boundary ridge line 60.

  The unit surface 50 is a surface defined by certain sections ab, bc, cd, and da that constitute the boundary ridge line 60. The boundary ridge lines drawn in the constant sections ab, bc, cd, and da, which are a part of the boundary ridge lines 60, are referred to as ridge lines of the unit surface in this specification, and are denoted by reference numerals 60ab, 60bc, 60cd, and 60da (see FIG. 9).

  Of the vertices a, b, c, and d of the unit surface 50, the vertex a when the flocked portion 20 is directed upward in the axial direction of the brush 1 is referred to as an upper vertex a, and the vertex c is referred to as a lower vertex c. In this case, the vertex b located on the left in the circumferential direction is referred to as the left vertex b, and the vertex d located on the right is referred to as the right vertex d.

The upper vertex a and the lower vertex c are located on a virtual circle C1 having the same diameter (see FIG. 10). The left vertex b and the right vertex d are located on another virtual circle C2 having the same diameter (see FIG. 11).
The radius r1 of the virtual circle C1 and the radius r2 of the virtual circle C2 are the radius of curvature of the recess of the unit surface 50. Preferably, the radius r1 of the virtual circle C1 matches the radius of curvature in the longitudinal direction of the finger ball of the average size of the user (the abdominal surface of the finger end), and the radius r2 of the virtual circle C2 is also the width of the finger ball. It is preferable to match the curvature radius in the direction.

  In other words, the unit surface 50 is smoothly recessed with the central point at the bottom between the opposing vertices a-c (see FIG. 10), and is smooth with the central point at the bottom between the opposing vertices b-d. (See FIG. 11). In the unit surface 50, the point located at the center between the vertices a-c and the point located at the center between the vertices b-d are the same, and are indicated by the symbol m.

  Each of the vertices a to d is curved rather than a point even if it is called a vertex. Therefore, it can be said that the ridge lines 60ab, 60bc, 60cd, and 60da of the unit surface constituting the unit surface 50 and the boundary ridge line 60 are lines formed by curves and straight lines.

  Further, the ridge lines 60ab, 60bc, 60cd, 60da and the vertices a, b, c, d of the unit surface are surrounded by portions that become actual surfaces in the unit surface 50, in other words, the ridge lines 60ab, 60bc, 60cd, 60da. Positioned relatively outward from the axial center C (see FIGS. 1 and 8) of the grip portion 30 relative to the portion (hereinafter referred to as a real surface portion) 50 ′ (see FIGS. 9 to 11). .

  Furthermore, the unit surface 50 is relatively displaced by a length that is one-half of the length of the diagonal line ac in the axial direction of the gripper 30 with respect to the unit surface 50 adjacent to the gripper 30 in the circumferential direction (FIG. 1). And FIG. 5).

  On the other hand, the ridgelines 60ab, 60bc, 60cd, and 60da of the unit surface protrude outward most at the ends of the upper vertex a and the lower vertex c, and the axial centers C as they go to the middle of the ridgelines 60ab, 60bc, 60cd, and 60da. The distance from is reduced (see FIGS. 8 to 11). That is, the upper vertex a and the lower vertex c overlap when the unit surface 50 is projected in the axial direction, and the left vertex b and the right vertex d overlap when projected in the width direction.

  The diagonal line ac intersects with the diagonal line bd and is positioned outside the axis C with respect to the diagonal line bd. Because of this positional relationship, it can be said that the quadrilateral abcd is a surface that is not on the same plane, that is, a curved or bent surface.

  The rhombus dimensions as the unit surface 50 are the diagonal lines in the circumferential direction (hereinafter referred to as the circumferential diagonal line) bd when viewed in a plane, W (see FIG. 11), and the diagonal lines in the axial direction when viewed in the same plane. (Hereinafter, the diagonal in the axial direction) When the length of ac is L (see FIG. 10), W and L are the maximum width in the circumferential direction and the maximum length in the axial direction, respectively, when the unit surface is viewed in a plane.

The length L of the axial diagonal line ac is different from the actual length L ′ (see FIG. 10) in the longitudinal section of the unit surface 50 along the axial diagonal line ac, and the length W of the circumferential diagonal line bd. It is clear from the above description that the actual length W ′ (see FIG. 11) in the cross section of the unit surface 50 along the circumferential diagonal bd is different.

Therefore, as shown in FIGS. 8, 10 and 11, the unit surface 50 appears as a curved or U-shaped recess.
Accordingly, the cross section of the grip portion 30 on which the three-dimensional uneven portion 40 having a large number of unit surfaces 50 is formed is a concave curved side that is recessed toward the axis C as shown in FIGS. It is substantially rectangular and each vertex of the rectangular cross section is somewhat rounded.

The specific dimensions of the unit surface are as follows.
Diagonal length W in the circumferential direction of the unit surface: 13 mm to 15 mm
Axial diagonal length L of unit surface: 23 mm to 25 mm
Angle of vertex a: 60 °
Angle of vertex b: 120 °
Angle of vertex c: 60 °
Angle of vertex d: 120 °
Length of ridgeline 60ab / 60bc / 60cd / 60da of unit surface: 13 to 15 mm
Radius r1 of virtual circle C1: 19 mm to 24 mm
Radius r2 of virtual circle C1: 19 mm to 24 mm

  A fit transmitted from the grip 30 when the hairdressing and beautician grips the grip 30 having such a three-dimensional uneven portion 40 (see FIG. 3) or holds it with a dominant finger (see FIG. 4). (The multiple lines shown in FIGS. 3 and 4 are hair. FIG. 3 shows a case where the brushing operation is performed by gripping the brush very lightly, and FIG. 4 shows a dominant index book.) This is a case of performing a delicate brushing work such as working with.)

  Since the brush 1 has such a good fit, the surface of the grip 30 and the palm (dominant finger) when the brush 1 is picked up compared to a brush without the three-dimensional uneven portion 40 in the grip. Since the brush 1 is less likely to slip from the palm and fingers, it is difficult to leave. In addition, each of the unit surfaces 50 constituting the three-dimensional uneven portion 40 has a concave curved surface shape in which each of the unit surfaces 50 is smoothly recessed, so that the touch when the brush 1 is held is good. Get used to it.

  For this reason, when performing a delicate brushing work, a delicate feel is transmitted to the hairdressing and beautician via the brush 1. Therefore, even when brushing a person whose hair quality is delicate, it is possible to put in an optimum and delicate force that meets the person. Moreover, even if the brush 1 is grasped lightly, it is hard to fall.

  Furthermore, since many unit surfaces 50 are formed in almost the entire outer peripheral surface of the grip portion 30, there is an anti-slip effect wherever the grip portion 30 is held. As a result, workability is improved as compared with a conventional brush that cannot obtain an anti-slip effect unless the grip 50 is a specific portion. Further, since the finger is in contact with the three-dimensional uneven portion 40 whenever the brush is rotated by the operation of the gripping portion, the degree of close contact with the palm or the fingertip is not lost.

The brush 11 of Example 2 is demonstrated with reference to FIGS.
The difference between the brush 11 of the second embodiment and the brush 1 of the first embodiment is that the cross section of the flocked portion 201 is substantially triangular, and the shape of the unit surface of the gripping portion is slightly different in the drawing.
Therefore, the same parts are denoted by the same reference numerals and description thereof is omitted.

The roll brush 11 is shaped so that its transverse cross section slightly has three vertices of an equilateral triangle, and the hair is also planted in the pier portion (see FIG. 15).
In addition, the unit surface 501 of the gripping portion 301 of the roll brush 11 is shown as a shallower recess than the unit surface 50 of the first embodiment in the drawing (see FIGS. 8 and 15). It is in the same category as various dimensions and angles of the unit surface 50.

  In the first embodiment, the crossing point portion 70 of the boundary ridge line 60 crosses linearly, but in the second embodiment, as shown in FIG. 13, the crossing region 701 has a dotted shape.

  Even in the second embodiment, as in the first embodiment, it can be said that the fit when the grip portion 301 of the roll brush 1 is gripped by the three-dimensional uneven portion 40 or held with a dominant finger is extremely excellent. Even when the beautician grips the gripping part 301 lightly or works with a dominant index book, the gripping part 301 is difficult to separate from the palm.

  For this reason, when performing delicate brushing work, adjustment by a delicate force can be performed. Therefore, it is possible to make it difficult to fall even if the brush is lightly grasped, as well as suitable brushing is possible.

  The third embodiment differs from the first and second embodiments in that the flocked portion and the grip portion can be separated by the screwing means 80 of the male screw 80a and the female screw 80b. In the third embodiment, an example in which the screwing means 80 is applied in the case of the first embodiment is illustrated.

  In the third embodiment, in addition to the effects of the first and second embodiments, by preparing several gripping portions having different degrees of unevenness of the three-dimensional uneven portion 40, the beauty / barber can make his own It can be an original brush that best fits your palm and fingertips.
