Abstract
Description
Technical Field
[0001] The present invention relates to a hairbrush.
Background Art
[0002] Conventionally, for example, a hairbrush for winding hair in a roll shape (hereinafter, a conventional example) has been proposed.
[0003] As shown in FIG. 9, in this conventional example, a large number of brush materials 31a of the same length are radially provided on the outer peripheral surface of the brush shaft 30. These brush materials 31a are arranged in parallel in a plurality at predetermined intervals in the longitudinal direction of the brush shaft 30 to form a brush row 31. Further, a plurality of rows of the brush row 31 are provided at predetermined intervals in the outer peripheral direction of the brush shaft 30. For example, by inserting the hair H between the brush materials 31a and applying tension while rotating the brush shaft 30, the hair H can be wound.
Summary of the Invention
Problems to be Solved by the Invention
[0004] By the way, for this type of hairbrush (roll brush), for the purpose of enabling good winding processing, the brush material 31a is provided at an appropriate density (the interval in the longitudinal direction of the brush shaft between the brush materials constituting the brush row and the interval in the outer peripheral direction of the brush shaft between the brush rows are appropriately set). However, when actually trying to wind the hair H using the conventional example, the hair H slips at the tip of the brush material 31a and it is difficult to enter between the brush materials 31a (see FIG. 9). Therefore, when strongly pressing the brush material 31a against the hair H to force the hair H to enter between the brush materials 31a, the hair H may deeply enter too close to the brush shaft 30 by the momentum (see FIG. 10), and the hair H may get entangled.
[0005] The present invention has been made in view of the above-described problems, and provides a very practical hairbrush that has never existed before.
Means for Solving the Problems
[0006] The gist of the present invention will be described with reference to the accompanying drawings.
[0007] A hairbrush in which a plurality of brush materials are provided on the outer peripheral surface of a brush shaft 10, wherein the brush materials are arranged in parallel in a plurality of rows at a predetermined interval in the longitudinal direction of the brush shaft 10 to form a brush row, and further, the brush row is provided in a plurality of rows at a predetermined interval in the outer peripheral direction of the brush shaft 10. In addition, the brush row includes, when viewed from the end direction of the brush shaft 10, a plurality of first brush rows 1 in which the tips of the brush materials 1a reach a circle L centered on the axis of the brush shaft 10, and a second brush row 2 provided between the first brush rows 1 and the tips of the brush materials 2a do not reach the circle L. It relates to a hairbrush characterized by having a configuration.
[0008] Further, in the hairbrush according to claim 1, the brush shaft 10 has a circular cross-section, and the brush material 2a of the second brush row 2 is set to a length shorter than that of the brush material 1a of the first brush row 1. It relates to a hairbrush characterized by that.
[0009] Further, in the hairbrush according to any one of claims 1 and 2, all the brush materials 1a of the first brush row 1 have the same length, and all the brush materials 2a of the second brush row 2 have the same length. It relates to a hairbrush characterized by that.
[0010] Further, in the hairbrush according to any one of claims 1 and 2, all the brush materials 1a of the first brush row 1 have the same length, and the second brush row 2 includes another second brush row 2 in which the lengths of the brush materials 2a are different. It relates to a hairbrush characterized by that.
[0011] Further, in the hairbrush according to claim 4, all the brush materials 2a of the other second brush row 2 have the same length. It relates to a hairbrush characterized by that.

Modes for Carrying Out the Invention
[0014] Preferred embodiments of the present invention will be briefly described based on the drawings to show the operation of the present invention.
[0015] When the hairbrush according to the present invention is applied to the hair H, since there is a second brush row 2 between the first brush rows 1 where the tip of the brush material 2a does not reach the circle L centered on the axis of the brush shaft 10, the resistance to the entry of the hair H becomes small. Compared with the conventional examples described above, the hair H can easily enter between the brush materials 1a of the first brush row 1 by simply pressing lightly. However, since there is a second brush row 2 between the brush materials 1a of the first brush row 1, the brush material 2a of the second brush row 2 becomes a resistance to the hair H that has entered between the brush materials 1a of the first brush row 1. It is prevented from entering too much beyond necessity. That is, in the present invention, the hair H easily enters between the brush materials, but it is difficult to enter near the brush shaft 10.
[0016] Therefore, since an appropriate tension can be applied to the hair H, good winding processing becomes possible. Also, since the hair H that has entered between the brush materials does not enter near the brush shaft 10, the hair H is prevented from getting entangled, and thus the damage to the hair H is also reduced.
Embodiment
[0017] A specific embodiment of the present invention will be described based on the drawings.
[0018] This embodiment is a hairbrush in which a large number of brush materials are radially provided on the outer peripheral surface of a brush shaft 10 having a gripping portion 10a on the proximal end side. The brush materials are pin-shaped bodies having a predetermined diameter, and a plurality of them are arranged in parallel at predetermined intervals (equal intervals) in the longitudinal direction of the brush shaft 10 to form a brush row. Further, a plurality of brush rows are provided at predetermined intervals (equal intervals) in the outer peripheral direction of the brush shaft 10.
[0019] Also, in this embodiment, as shown in FIG. 2 for example, in the view from the end direction of the brush shaft 10, the brush row includes a plurality of first brush rows 1 in which the tips of the brush materials 1a reach a circle L (a perfect circle) centered on the axis of the brush shaft 10, and a second brush row 2 provided between the first brush rows 1 and the tips of the brush materials 2a do not reach the circle L.
[0020] Specifically, the brush shaft 10 has a circular cross-section, the brush materials 2a of the second brush row 2 are set to a length shorter than that of the brush materials 1a of the first brush row 1, all the brush materials 1a of the first brush row 1 have the same length, and all the brush materials 2a of the second brush row 2 have the same length.
[0021] Furthermore, in this embodiment, the second brush row 2 includes another second brush row 2 in which the lengths of the brush materials 2a are different. The other second brush row 2 is configured such that the tip of the brush material 2a is farther from the above-mentioned circle L centered on the axis of the brush shaft 10 than the tip of the brush material 2a of one second brush row 2. Specifically, the brush material 2a of the other second brush row 2 is set to a length shorter than that of the brush material 2a of one second brush row 2.
[0022] Also, in this embodiment, the brush material 1a of the first brush row 1 is formed by shaping an appropriate synthetic resin member into a pin shape, and the brush material 2a of the second brush row 2 is formed by bundling animal hairs into a pin shape. Note that the material of each brush material is not limited to the above such as metal, and the material of each brush material in each brush row can also be appropriately selected.
[0023] Also, in this embodiment, as a configuration for realizing the positional relationship between the tips of the brush materials 1a and 2a (the relationship of whether the tips of the brush materials 1a and 2a reach the circle L centered on the axis of the brush shaft 10, and the relationship of the distances at the tips of the brush materials 1a and 2a to the circle L) that constitute the first brush row 1 and the second brush row 2 respectively, as described above, a brush shaft 10 having a circular cross-section is adopted as the brush shaft 10, and the lengths of the respective brush materials 1a and 2a are made different. However, other configurations may be used, such as a configuration in which the above relationship is realized by setting the cross-sectional shape of the brush shaft 10 while making the lengths of the brush materials 1a and 2a the same.
[0024] Hereinafter, specific embodiments (arrangement examples of the first brush row 1 and the second brush row 2 with respect to the brush shaft 10) will be described.
[0025] <Example 1> As shown in FIGS. 1 and 2, a first brush row group 1' composed of a plurality of rows (two rows) of first brush rows 1 is provided at four locations at equal intervals in the outer circumferential direction of the brush shaft 10, and a second brush row 2 (one second brush row 2 and another second brush row 2) is provided between the four first brush row groups 1'.
[0026] Specifically, a second brush row group 2' composed of multiple rows (two rows) of second brush rows 2 is provided at the central portion between adjacent first brush row groups 1', and furthermore, one row of another second brush row 2 is provided between each of the first brush row groups 1' and the second brush row group 2'.
[0027] That is, with the center between adjacent first brush row groups 1' (first brush rows 1) as the boundary, one second brush row 2 and another second brush row 2 are symmetrically arranged. That is, they are arranged in the order of the first brush row 1, another second brush row 2, one second brush row 2, one second brush row 2, another second brush row 2, and the first brush row 1. Therefore, no matter in which direction the brush shaft 10 rotates, the brush materials 1a and 2a will contact the hair H under the same conditions.
[0028] In addition, as shown in FIG. 3, the brush rows adjacent to each other in the outer peripheral direction of the brush shaft 10 are arranged in a positional relationship (zigzag) in which the brush materials are displaced in the longitudinal direction.
[0029] Since this embodiment is configured as described above, it has the following effects.
[0030] When the hairbrush according to this embodiment is applied to the hair H, there is a second brush row 2 between the first brush rows 1 where the tip of the brush material 2a does not reach the circle L centered on the axis of the brush shaft 10. Therefore, the resistance to the entry of the hair H is reduced. Compared with the above-described conventional example, the hair H can easily enter between the brush materials 1a of the first brush row 1 just by gently pressing. However, since there is a second brush row 2 between the brush materials 1a of the first brush row 1, the brush material 2a of the second brush row 2 becomes a resistance to the hair H that has entered between the brush materials 1a of the first brush row 1, preventing the hair H from entering too much (the hair H also enters between the brush materials 2a of one second brush row 2). And further, when a strong tension is applied, the entry of the hair H progresses, but the brush material 2a of the other second brush row 2 becomes a further resistance to prevent excessive entry (the hair H also enters between the brush materials 2a of the other second brush row 2 to some extent). That is, in this embodiment, the hair H can easily enter between the brush materials, but it is difficult to enter near the brush shaft 10.
[0031] Therefore, according to the present embodiment, an appropriate tension can be applied to the hair H, enabling good winding processing. In addition, the hair H that has entered between the brush materials does not enter near the brush shaft 10, so the hair H is prevented from getting entangled, and consequently, the damage to the hair H is also reduced.
[0032] In addition, in the present embodiment, since the hair H is not entangled, the load applied to each of the brush materials 1a and 2a is reduced, so the durability as a hairbrush is improved.
[0033] In addition, in the present embodiment, the brush shaft 10 has a circular cross-section, and the brush material 2a of the second brush row 2 is set to a length shorter than that of the brush material 1a of the first brush row 1. Therefore, not only can the above-described effects be surely achieved, but also due to the simple structure, the cost is low and the mass productivity is excellent.
[0034] In addition, in the present embodiment, since all the brush materials 1a of the first brush row 1 have the same length, and all the brush materials 2a of the second brush row 2 have the same length, while having a basic configuration that enables good winding processing, the above-described effects can be achieved.
[0035] In addition, in the present embodiment, since the second brush row 2 includes another second brush row 2 having different lengths of the brush materials 2a, the entry of the hair H can be prevented by the presence of the other second brush row 2. Moreover, by providing the three types of brush rows described above, the following effects can also be achieved.
[0036] That is, the first brush row 1 (brush material 1a) grabs the hair H on the surface (outer side) so as not to let the entire hair bundle escape. While suppressing excessive entry of the hair H with one second brush row 2 (brush material 2), it gives a hair flow and luster, and suppresses excessive entry of the hair H with the other second brush row 2 (brush material 2a).
[0037] <Example 2> As shown in FIG. 6, a first brush row 1 is provided in a single row at five equally spaced positions in the outer circumferential direction of the brush shaft 10, and a second brush row 2 (one second brush row 2 and the other second brush row 2) is provided between the first brush rows 1 at these five positions.
[0038] Specifically, a second brush row group 2' composed of multiple rows (two rows) of the other second brush rows 2 is provided at the central position between adjacent first brush rows 1, and further, one second brush row 2 is provided in a single row between each first brush row 1 and the second brush row group 2'.
[0039] That is, the other second brush row 2 and one second brush row 2 are symmetrically arranged with the center between adjacent first brush rows 1 as the boundary, that is, arranged in the order of the first brush row 1, one second brush row 2, the other second brush row 2, the other second brush row 2, one second brush row 2, and the first brush row 1. Therefore, no matter whether the brush shaft 10 is rotated in the forward or reverse direction, the brush materials 1a and 2a will contact the hair H under the same conditions.
[0040] The rest is the same as in the first embodiment.
[0041] <Example 3> As shown in FIG. 7, a first brush row 1 is provided in a single row at six equally spaced positions in the outer circumferential direction of the brush shaft 10, and a second brush row 2 (one second brush row 2 and the other second brush row 2) is provided between the first brush rows 1 at these six positions.
[0042] Specifically, the other second brush row 2 is provided in a single row at the central position between adjacent first brush rows 1, and further, one second brush row 2 is provided in a single row between each first brush row 1 and the other second brush row 2.
[0043] That is, with the center between adjacent first brush rows 1 as the boundary, another second brush row 2 and one second brush row 2 are symmetrically arranged, that is, they are arranged in the order of the first brush row 1, one second brush row 2, another second brush row 2, one second brush row 2, and the first brush row 1. Therefore, no matter whether the brush shaft 10 is rotated in the forward or reverse direction, the brush materials 1a and 2a will contact the hair H under the same conditions.
[0044] The rest is the same as in Example 1.
[0045] <Example 4> As shown in FIG. 8, one row of first brush rows 1 is provided at seven equally spaced positions in the outer peripheral direction of the brush shaft 10, and second brush rows 2 (one second brush row 2 and another second brush row 2) are provided between these seven first brush rows 1.
[0046] Specifically, one row of one second brush row 2 is provided at the central position between adjacent first brush rows 1, and furthermore, one row of another second brush row 2 is provided between each first brush row 1 and the one second brush row 2.
[0047] That is, with the center between adjacent first brush rows 1 as the boundary, one second brush row 2 and another second brush row 2 are symmetrically arranged, that is, they are arranged in the order of the first brush row 1, another second brush row 2, one second brush row 2, another second brush row 2, and the first brush row 1. Therefore, no matter whether the brush shaft 10 is rotated in the forward or reverse direction, the brush materials 1a and 2a will contact the hair H under the same conditions.
[0048] The rest is the same as in Example 1.
[0049] Note that the present invention is not limited to Examples 1, 2, 3, and 4, and the specific configurations of each constituent element can be appropriately designed.
