Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a hairbrush.

[Conventional technology and its problems]

In conventional hair brushes, the numerous pins provided on the brush face wall are fixed to the brush body and cannot be removed, so if you want to use a hair brush with pins of different hardness, length, and arrangement. It was necessary to prepare multiple types of hair brushes. Additionally, there were problems in manufacturing, such as the need to prepare injection molds for each type of hairbrush.

The present invention solves the above problems, and by simply preparing one hair brush, it is possible to attach hard pins to a certain area of the brush surface wall, and to attach long and short pins at desired positions. It is also possible to change the direction of each pin with respect to the brush handle, and the purpose is to easily manufacture a wide variety of hair brushes by sharing one type of brush main body.

[Means for solving problems]

In the present invention, a bristle pin unit in which a plurality of bristle pins are integrally protruded from a small base is fitted and fixed into a large number of holes provided in the brush face wall of the brush main body, and A plurality of locking grooves or one or more locking protrusions are provided on the inner circumferential surface at equal circumferential pitches, and one or more locking grooves are correspondingly provided on the outer peripheral surface of the small base of the bristle pin unit. It is provided with a locking protrusion or a plurality of locking grooves.

[Effect]

If you want to replace a certain area of the brush face wall with another bristle pin of different hardness, length, thickness, or number, pull out the pin that is already installed from the hole and fit and secure the desired pin into the hole. do it.

Once a pin unit containing multiple bristle pins is pulled out of the hole, the orientation of the bristle pins can be changed by changing the angle appropriately and then fitting and fixing it back into the original hole. At the same time, by changing the distance between the pins, it is possible to change the resistance that the hair receives during brushing.

Furthermore, in manufacturing, many types of hair brushes can be obtained by sharing one type of brush body and attaching various bristle pin units in various orientations and arrangements.

〔Example〕

Embodiments of the present invention will be explained in detail based on the drawings.

In FIGS. 1, 2, and 3, 1... is a plastic bristle pin unit, and the pin unit 1... is composed of a plurality of bristle pins 2...
and a small base 3 from which the bristle pins 2 are integrally protruded. Reference numeral 4 designates a brush main body made of plastic, and pin units 1 are fitted and fixed into a large number of holes 6 provided in the brush face wall 5. The inner peripheral surface 7 of the hole 6 is provided with a plurality of locking grooves 8 having the same circumferential pitch, and
Correspondingly, one or more locking protrusions 10 are provided on the outer circumferential surface 9 of the small base plate 3. Specifically, each pin unit 1 is securely fixed to the brush face wall 5 by fitting the small base 3 into the hole 6, and will not come off due to the force applied during normal brushing. As shown in FIG. 4, the portion of the small base 3 that supports the base of the bristle pin 2 is
It has a thin elastically deformable wall portion 11 that allows the pins 2 to tilt, and is formed to be considerably thinner than the other portions of the small base plate 3. Therefore, as shown by the imaginary lines in the figure, during brushing, the bristle pins 2 receive resistance from the skin or hair due to the elastic deformation of the wall portions 11, and are pushed against the brush surface wall 5 in a substantially straight line. It tilts easily. Note that there is a back cover 1 on the back side of the brush body 4.
2 is installed.

Therefore, the pin unit 1... can be easily pulled out in the direction of arrow A in FIG. 2, and by fitting another pin unit 1... in the direction of arrow B into the same hole 6... can be exchanged with To change the orientation of the bristle pins 2, as shown in Fig. 5, once the pin unit 1 is removed, the position of the bristle pins 2 is rotated in the clockwise direction C by a desired angle θ from the original mounting position. It can also be installed in a moved state. In this way, it is possible to set the distance between the pins 2 to a desired value in the same brushing direction D, and it is possible to improve the feeling of use and to enhance the hair styling effect of brushing, for example. .

Regarding the material of pin unit 1..., if we adopt a thermoplastic polyester elastomer (product name: Hytrel, manufactured by Toray Dupont), it will be less expensive than nylon and polyester, which are the bristle materials used in conventional hair brushes. It has excellent flexibility, heat resistance, and chemical resistance, so even if force is applied when brushing, it can release the force, and it is soft to the scalp and does not damage the scalp. and,
Hair dryer heat (approximately 80℃) during hair styling
It has excellent durability and is unaffected by makeup products (hair spray, styling foam, blow-drying agents, etc.).

Unlike the case of the above embodiment, FIGS.
As shown in the figure, a locking convex portion 10 is provided on the brush surface wall 5.
may be provided, and the locking grooves 8 may be provided on the small bases 3. Further, although only two pins 2 of each pin unit 1 are illustrated, the number may be three or more.

FIG. 7 shows a case where pins 2 are arranged in a mixed manner, with hard pins 2 on both sides of the brush surface wall 5.
By arranging ..., it is possible to scoop up hair sufficiently even for people with a large amount of hair, and by arranging soft pins 2 ... in the center part M, it has the effect of making the contact with the scalp soft. . Also, as shown in Fig. 8, if a hard pin 2 is placed at the tip N, the tip of the brush body 4 can be used like a hand, and soft pins 2 are placed in other parts. By doing so, it is possible to achieve soft brushing on the skin.

9 and 9 show cases in which two types of pins 2 with different lengths are arranged, with short pins 2 in the central part M shown by the imaginary line of the brush surface wall 5, and short pins 2 in other parts. A long pin 2... was placed. FIG. 10 shows a case where pins 2 of two types, long and short, are arranged alternately across the brush face wall 5. As shown in FIGS. 9 and 10, by making the pins 2 long and short, the bristle pins 2 will not penetrate the hair uniformly, and this will result in an unprecedented brushing effect.

In addition, contrary to FIG. 2, attach and detach the bristle pin unit 1 from the back side of the brush face wall 5, and
It is also extremely desirable to make the surface opening edge of the hole 6 small in diameter so that it cannot escape to the front surface (not shown).

The planar shape of the small base 3... is shown in Figures 11 and 11.
As shown in the figure, it may have a polygonal shape such as a star shape or a hexagonal shape, and in this case, the holes 6 of the brush face wall 5 are formed corresponding to the shape. Although not shown, it is also preferable to have a flower shape. In any case, the locking convex portions 10 and the locking grooves 8 fit together.

[Effect of idea]

In this way, in the present invention, the pin unit 1...
Since it was decided to fit and fix the pin unit 1 into the hole 6 of the brush face wall 5, the user can install the pin unit 1 after purchase.
Bristle pins 2 with different hardnesses and lengths can be installed at desired positions on the brush surface wall 5, and by combining these, an unprecedented arrangement pattern can be created. .

By providing the locking groove 8 or the locking protrusion 10 in the hole 6 of the brush face wall 5 and the small base 3,
In particular, the orientation of the plurality of pins 2 of each pin unit 1 with respect to the brush handle can be changed in various ways, preventing the pins 2 from rotating freely, and the distance between the pins 2 can be changed in various ways. It can be changed. Therefore, it is convenient when you want to add various curls to your hair or, conversely, to make it straight, and the flow that can be applied to your hair can also be varied.
This has the effect of making various brushing possible. In terms of manufacturing, only one type of brush main body 4 is used.
By sharing the same, a wide variety of hairbrushes can be easily manufactured, and its practical effects are significant.
