DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement of hair brushes, and particularly aims to ensure the attachment of a rubber sheet on which groups of brush bristles are arranged in rows, such as vertically and horizontally, to a hair brush base.

Conventionally, in order to attach the rubber sheet to the hair brush base, first, the rubber sheet is integrally formed into a rectangular planar shape and a gate-shaped cross section, and brush bristles made of synthetic resin or the like are planted on the flat part, while the hair brush base is attached to the hair brush base. forming a rubber sheet attachment part formed into a cylindrical shape and provided with a notch opening groove in its longitudinal direction, and wrapping the outer periphery of the rubber sheet attachment part so as to cover the flat part of the rubber sheet, Both legs of the rubber sheet are fitted into the cutout opening grooves, and in order to prevent the legs from coming off, the rubber sheet is fixed by a fixing member having a pinching part inserted between the legs.

However, the wall thickness of both legs is uniform, and the notch surfaces of the notch opening groove are gradually spaced apart from each other in the radial direction.
・Because it is inclined in the shape of a square, and the clamping part of the fixing member is tapered to correspond to the notch surface, the surface pressure on the clamping part is low, and the width between the two legs is narrow in the fixed state. The width is approximately the same as the width of the opening groove, and this has caused problems such as the legs falling out during use.

Therefore, the present invention was devised to solve the above-mentioned problems, and its features include a gate-shaped cross section and a rectangular planar shape, which is equipped with bristles and has legs on both ends in the width direction. Wrap the rubber sheet around the cylindrical rubber sheet attachment part of the hair brush base, insert both legs of the rubber sheet into a single notch opening groove formed in the rubber sheet attachment part, and insert the rubber sheet between the inserted legs. In the brush into which the inserting part of the fixing member is inserted, the notch opening groove is formed to have notch surfaces parallel to each other, and both legs of the rubber sheet are formed so that the outer wall surface thereof expands outward in the width direction and the tip side gradually extends. The clamping member is formed into a trapezoidal shape with a thickness within the width of the fixing member, and the clamping member is inserted between the legs so that the distal end of the inner wall surface of the clamping part spreads to both sides of the leg from the notch surface of the notch opening groove. The insertion part is formed into a plate shape with approximately the same thickness over the entire area, and a presser part is provided at the radially outer end of the insertion part to press both ends of the rubber sheet into the rubber sheet attachment part, and the notch surface of the notch opening groove The fixing member is provided so as to protrude further outward in the circumferential direction and to have a substantially T-shaped cross section.

Embodiments of the present invention will be described below in detail based on the drawings. In FIGS. 1 to 6, 1 is a hair brush base made of synthetic resin, which is composed of a grip part 2 and a rubber sheet attachment part 3. There is.

A fixing member 6 fixes the rubber sheet 4 to the rubber sheet attachment part 3.

The rubber sheet attachment part 3 extends in a cylindrical shape on one side of the grip part 2, and has a single notch in the longitudinal direction of the wall having notch surfaces 7a, 7a parallel to the axis and parallel to each other. An open groove 7 is formed, and an open opening 8 is formed at the front end thereof.

The rubber sheet 4 is integrally formed of an elastic material such as rubber and has a rectangular planar shape and a gate-shaped cross section.
A large number of brush bristles 5 made of synthetic resin are penetrated and fixed in an upwardly protruding manner, and both legs 9, 9 are formed into a trapezoid shape with outer wall surfaces '9a, 9a extending downward and becoming thick. The flat part 4a, more specifically the back surface thereof, is wrapped so as to cover the outer periphery of the rubber sheet attachment part 3, and both legs 9, 9 are removably fitted over the entire length of the notch opening groove 1. has been done.

(See FIG. 4) The fixing member 6 is made of synthetic resin and has a T-shaped cross section, and its hanging portion is connected to the notch opening groove 7.
The inserting portion 10 has a length approximately corresponding to the entire length of the inserting portion 10, and at the outer end in the radial direction of the inserting portion 10, a presser portion 12 for pressing both ends of the rubber sheet 4 into the rubber sheet attaching portion 3 is provided on the notch surface 7a.
, 7a, and is provided at one end with a circular decorative portion 11 that closes the opening 8 of the rubber sheet attachment portion 3.

The sandwiching part 1'0 is inserted and removably inserted between the leg parts 9, 9 fitted in the notch opening groove 7, and is pressed against the outer walls +ff19a, 9a of the leg parts 9, 9. 9,
The legs 9 are held so that the width of the lower part thereof is wider than the width of the notch opening groove 7, thereby preventing the legs 9, 9 from coming off from the notch opening groove 7.

The decoration part 11 is arranged correspondingly to the front part of the opening 8 to close the opening 8 and also close the boundary between the outer periphery of the rubber sheet attachment part 3 and the inner surface of the rubber sheet 4.

In the configuration of the above embodiment, when attaching the rubber sheet 4 to the rubber sheet attaching part 3, first the flat part 4a of the rubber sheet 4 is wrapped around the outer circumference of the rubber sheet attaching part 3, and both leg parts 9, 9 into the notch opening groove 7.

In this state, the clamping part 10 of the fixing member 6 is clamped between the legs 9, 9 to prevent the legs 9, 9 from coming off. The outer wall surfaces 9a, 9a of the formed legs 9, 9 are biased in the width direction of the notch opening groove 1, and the inner wall surfaces are held wider than the width of the notch opening groove 7 inside the rubber sheet mounting portion 3, so that one of both legs Part 9゜9
Since the wall thickness is increased, the restoring force due to the elastic force is strong, and the surface pressure against the inserted portion 11 is maintained in a high state.

Therefore, compared to the conventional case in which the width between both legs 9, 9 is approximately the same width as the width of the notch opening groove 7 when the inserting part 11 is inserted, the legs 9, 90 The surface pressure is strong, and both legs 9, 9 are inside the rubber sheet mounting part 3.
Since the width between them is wider than the width of the notch opening groove 1, it is possible to reliably prevent the legs 9.9 from coming off.

According to the present invention, the notch opening groove 1 is formed by the notch surfaces 7 parallel to each other.
a, 7a, and the inserting part 1 of the fixing member 6
0 is formed into a plate shape with approximately the same thickness over the entire area, so the surface pressure due to the elastic force of the legs 9, 9 is increased, and the notch surface 7a of the notch opening groove γ.

A rubber sheet 40 is inserted between 7a and the sandwiched part 11 of the fixing member 6.
Both legs 9, 9 can be strongly held, and at the same time, the rubber sheet 4
0 The pinching part 10 can be held between the two leg parts 9, 9 so as not to come off.

In addition, since both legs 9, 9 of the rubber sheet 40 are formed into a trapezoidal shape in which the outer wall surface thereof spreads outward in the width direction and gradually becomes thicker at the tip end, a sandwiched part '10 is formed between one leg part 9, 9. When inserting the □ seat mounting part 3
The rubber sheet 4 can be strongly pushed inward in the radial direction, thereby increasing the degree of attachment of the rubber sheet 4 to the seat attachment portion 3.
Also from this point of view, the rubber sheet 4 can be firmly and beautifully attached to the seat attachment portion 3.

Moreover, by inserting the sandwiching part 10 between the legs 9, 9, the distal end side of the inner wall surface of the sandwiching part 10 spreads out to both sides of the legs 9, 9 from the notch surfaces 7a, γa of the notch opening groove 1. Also, the legs 9, 9 can be more reliably prevented from slipping out of the cutout opening groove γ.

Furthermore, at the radially outer end of the inserting part 10, a presser part 12 for pressing both ends of the rubber sheet 40 into the rubber sheet attaching part 3 is provided, which protrudes outward in the circumferential direction from the notch surfaces 7a and γa of the notch opening groove T, and the fixing member 6 Since the rubber sheet 4 is provided so as to have a substantially T-shaped cross section, the presser portion 12 can prevent the legs 9, 9 from coming loose from the notch opening groove T, and the rubber sheet 4
can be firmly held in close contact with the seat attachment part 3.

Therefore, the rubber sheet 4 and the fixing member 6 can be firmly and beautifully attached to the seat attaching part 3 with a very simple structure without requiring any special fixing means between the fixing member 6 and the sheet attaching part 3. .
