Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair grip in which a resin spring is interposed between a pair of holding pieces made of resin, and the holding pieces are openably and closably provided. It is characterized in that a spring interposed between the pieces is integrally formed from one holding piece.

[0002]

2. Description of the Related Art Conventionally, hair grips in which a spring interposed between a pair of holding pieces together with resin are each made of resin.
For example, Japanese Patent No. 2918837, registered utility model No. 3
Nos. 024771 and 3027471. The hair grip of the prior application uses a coil spring because a pair of holding pieces for holding the hair and a spring formed in a U-shape so as to press the two holding pieces against each other are all formed of a resin molding. Compared to earlier hair grips, there were advantages such as easier installation of springs, easier assembly, suitable for mass production, and rust resistance,
In recent years, the cost of the resin grip has been required to be further reduced.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned demands, and has conventionally been made up of three parts of two holding pieces and one spring. An object of the present invention is to improve a hair clip so that it can be easily assembled and cost can be reduced.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a spring made of a resin material is interposed between a pair of holding pieces made of resin. In the hair grip assembled to open and close freely,
An arc-shaped spring is formed integrally with the holding piece by bringing the base end portion close to the hand side of one holding piece, and the arc portion of this spring is inserted through a window hole provided on the hand side of the other holding piece. And the leading end of the spring is received by a hook provided on the back side of the holding piece, while the overlapping portion of the holding pieces faces the arc of the spring. A hair grip, wherein the pair of holding pieces are assembled to be openable and closable by a restoring force of the spring and a pressure contact of an overlapped portion formed on the curved surface. Things.

[0005] As described above, the hair grip of the present invention in which a spring is provided integrally with one of the holding pieces, the number of parts is one.
In addition to the reduction in the number of points, the force required for the assembly can be reduced as compared with the conventional product, as described later, so that the cost can be reduced without impairing the ease of the assembly at all.

[0006] Also, one of the overlapping portions of the two holding pieces is provided with a ridge along the length direction, and the other is provided with a concave portion for fitting the ridge, and by fitting the uneven portion, the two holding pieces are provided. According to the second aspect of the present invention, the grip is prevented from disassembling and the grip is prevented from being disassembled. Furthermore, on the inner surface of the base end of the arc portion of the spring and the base end side of the curved portion of the other holding piece,
4. The invention according to claim 3, wherein the inclined portions are provided so as to engage with each other so that the engagement between the holding pieces is always maintained when the grip is not used. The stopper prevents accidental disassembly of the grip when closed, and enables stable use.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal side view of the embodiment, FIG. 2 is a longitudinal side view with a hair grip opened, and FIG. 3 is a perspective view.

In the drawing, reference numeral 1 denotes one holding piece which is located on the lower side in the normal state as shown in the figure, 2 denotes the other holding piece superimposed on the holding piece 1, and 3 denotes both holding pieces 1 And 2 are springs which are brought into pressure contact with each other by a storage force to maintain an assembled state.

The spring 3 causes the base end portion 4 to approach the hand side (left side in the figure) of one of the holding pieces 1 and draws a convex arc upward from the upper surface of the holding piece 1 as shown in the figure. The front end 6 is formed in a lateral groove shape on the back side (upper surface) of the holding piece 2 by inserting a window hole 5 provided on the hand side of the other holding piece 2 during assembly. The part 7 is spring-loaded.

Each of the holding pieces 1 and 2 has a portion facing the arc portion of the spring 3 formed on a downwardly convex curved surface as shown in the figure to provide overlapping portions 8 and 9 as described above. A restoring force of the spring 3 in which the tip portion 6 is received by the hook portion 7 as a spring;
Due to the joining of the overlapping portions 8 and 9 pressed against each other by the restoring force, the assembled state of the two holding pieces 1 and 2 without the hinge shaft is maintained even when the grip slightly swings. I have to. Also, in this embodiment, on one of the overlapping portions 9, ridges 13 along the length direction of the holding piece 2 are provided on the left and right of the overlapping portion, and the other overlapping portion 8 (in this embodiment, the holding piece On one side), a rectangular opening is provided as a concave portion 14 in which the above-mentioned ridge 13 is fitted, and by fitting the two concave and convex portions 13, 14, the side of both holding pieces 1, 2 joined without a bearing and a shaft. It prevents shake and prevents disassembly of the assembled grip.

Reference numeral 10 denotes a slope provided on the base end side of the arc portion 11 of the spring 3, and reference numeral 12 denotes a slope on the base end side of the overlapping portion 9 of the holding piece 2 so as to engage with the slope 10. It is the other slope part equipped. The slope 10 on the side of the spring 3 contacts the other slope 12 toward the proximal side as shown in FIGS. 1 and 3, thereby acting as a stopper against the restoring force of the spring 3, and holding the both sides when closed. The pieces 1 and 2 are prevented from being inadvertently disassembled, and the state when the grip is closed can be stably maintained.

In the hair grip having the above-described structure, the hand sides of the holding pieces 1 and 2 which are normally open in a U shape are strongly gripped against the accumulated force of the spring 3 as shown in FIG. Then, the tip portion opens while causing a slight slip on the joining surface of the overlapping portions 8 and 9 formed on the curved surface,
Can be used in the same way as a normal hair grip.

When assembling, the holding pieces 1 and 2 are attached to the end of a hook portion 7 formed in a lateral groove shape while intersecting the holding pieces 1 and 2 in an X shape while inserting the spring 3 into the window hole 5. Spring 3
The tip 3 is positioned and aligned in a straight line while being guided by the groove-shaped engaging portion 7, whereby the spring 3 is mounted and the assembly is completed. At this time, both the slope portions 10 and 12 serving as stoppers for the restoring force of the spring 3 are also engaged.

[0014]

According to the present invention constructed as described above and assembled as described above, the need to manufacture the spring separately is eliminated, the number of parts is reduced, and the conventional resin Since the labor required for mounting the spring, such as when assembling the hair grip, is also reduced, the assembly becomes easier. Also, there is no need to provide a bearing or a journal for hingedly holding the two holding pieces, and the cost can be reduced by reducing the number of parts. The present invention has excellent advantages as described above, and has an effect of being practically useful.
