[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention elastically bends a synthetic resin band member in the middle, and bends the bending pieces extending from the elastic bending portion so as to intersect each other, and the bending pieces of the both bending portions are relatively rolled. The first gist is a clip adapted to press the portion by the elasticity of the elastic bent portion and apply an inward pressing force to the elastic bent portion to open the bent piece apart from the pressed state. The synthetic resin strip is elastically bent in the middle, the roots of the bent pieces extending from the elastic bent parts are formed wide, and the wide parts of both bent pieces are crossed over each other, so that both bent pieces are separated from each other. The bent pieces are made to cross each other, and in this crossed state, the relative curving portions of the both bent pieces are brought into pressure contact with each other by the elasticity of the elastic bent portions, and the bending pieces are brought into pressure contact by applying inward pressing force to the elastic bent portions. The clip to open apart from the state to the second aspect.

That is, in the clip of the present invention, a synthetic resin band is elastically bent at an intermediate portion, and bending pieces extending from the elastic bending portion are made to intersect each other in a state where the bending pieces cross each other. The elastic bending portion is pressed by the elasticity. Then, by applying an inward pressing force to the elastic bent portion, the bent piece is opened apart from the pressed state. As described above, the clip of the present invention is provided with an elastic bending portion in the middle of a synthetic resin band-like member, and the elasticity of the elastic bending portion is used to press both bending pieces into contact with each other. Moreover, the elasticity of the spring 23 is not used to clamp both the clamp bodies 21. Therefore, in the clip of the present invention, the above-mentioned bar 23 can be omitted and the cost is reduced. Moreover, the clip of the present invention is made up of only a synthetic resin band (that is, only one part), and management such as inventory management is simplified. When manufacturing the clip of the present invention, first, a synthetic resin strip is elastically bent in the middle by a molding die, and the base of the bending piece extending from this elastic bending part is formed. Each of the bent pieces is formed into a wide shape, and then the wide portions of the bent pieces of the molded article are crossed over each other so that the bent pieces intersect each other. As a result, the molded product can be assembled into a clip, which simplifies the assembling work and saves time in this assembling work.

Also, in the clip of the present invention, when the pressing surface of the elastic bent portion is formed with the unevenness for preventing slippage, when the elastic bent portion is pressed inward with the finger, the finger does not slip and the finger is firmly held. The elastic bent portion can be pressed inward. Further, when the press-contact surface of the bending piece is formed with unevenness for preventing slippage, the bending piece does not slip when fixing the hair with the bending piece and can be firmly fixed to the hair. In addition, when the elastic bent portion is formed with a stopper portion that receives the root portion of each bent piece in a state where the bent pieces are separated from each other by a predetermined distance, each bent piece does not spread too much and This will prevent damage to the. Further, the elastic bending portion is composed of a plate body formed in a substantially U shape, the bending pieces extend from both lateral sides of the U shape of the plate body, and the phases of both bending pieces are shifted in the width direction of the plate body. When the elastic bent portion is pressed inward with fingers, the bent pieces do not interfere with each other and collide with each other.

In this embodiment, the clip is a hair clip, and as shown in FIG. 2 and FIG. 3, it is composed of a plate body bent and formed into a substantially U shape. , 3 is a central elastic plate portion (elastic bending portion) 1 which is elastically biased outward, and for holding a hair extending in a rod shape from the inner surfaces of both lateral sides 2 and 3 of the U shape of the central elastic plate portion 1. It is composed of legs (bending pieces) 4 and 5. Then, as shown in FIG. 4, a plurality of (5 in this embodiment) non-slip stoppers are provided on the outer surfaces (pressing surfaces) of the U-shaped lateral sides 2 and 3 of the central elastic plate portion 1. The projecting ridges 6 and 7 are arranged in parallel.

The above-mentioned both legs 4 and 5 are shown in FIGS. 5 to 7 (in these figures, only approximately half of the hair clip: one leg 5 and one lateral side 2 connected thereto are shown. As shown in (1), a pair of root portions 8 and 9 extending inwardly from the inner side surfaces of both lateral sides 2 and 3 of the central elastic plate portion 1 and intersecting each other, and each root portion 8 , 9 linearly extending from the hair holding portions 10 and 11. The phase of each of the root portions 8 and 9 is shifted in the width direction (vertical direction in the drawing) of each of the lateral sides 2 and 3. That is, the root 9 of one leg 5 extends from the lower part of the lateral side 2 connecting to it (see FIGS. 6 and 7), while the root 8 of the other leg 4 is , Extending from the upper part of the lateral side 3 connecting to this. As a result, when the leg portions 4 and 5 are expanded by pressing the outer side surfaces of both lateral sides 2 and 3 of the central elastic plate portion 1 inwardly (see FIG. 11), the root portions 8 of the leg portions 4 and 5 are , 9 do not interfere with each other and collide. At the same time, the edge portions 2a and 3a (see FIG. 1) of the lateral sides 2 and 3 which face the root portions 8 and 9 respectively receive the root portions 8 and 9 so that the leg portions 4 and 5 are exposed to the outside. I try not to spread too much. In this way, the edge portions 2a, 3a of the lateral sides 2, 3 which face the root portions 8, 9 relative to each other act as stopper portions. On the other hand, in the hair holding portions 10 and 11, the portions near the root portions 8 and 9 are formed into wide portions 10a and 11a. That is, in the hair holding portion 11 of the one leg portion 5 (the leg portion 5 extending from the lower portion of the lateral side 2), the portion near the root portion 9 is formed to project upward ( 6 and 7), the hair holding portion 10 of the other leg portion 4 (the leg portion 4 extending from the upper side portion of the lateral side 3) has the portion near the root portion 8 located downward. Both hair holding parts 10 and 11 are formed in a tapered shape. As shown in FIG. 8, each of the hair-holding portions 10 and 11 is provided with a large number of ridges 12 and 13 for preventing slippage on the hair-holding surface (pressure contact surface) thereof. Then, by the outward biasing force of the central elastic plate portion 1, the ridges 12, 13 are brought into contact with each other, so that the hair holding surfaces of the hair holding portions 10, 11 of the leg portions 4, 5 face each other. It is pressed into shape. In the figure, 14 is a connecting plate that connects the root portions 8 and 9 of the leg portions 4 and 5 and the lateral sides 2 and 3 that are connected to the leg portions 4 and 5, respectively, and positions and fixes the root portions 8 and 9.

Such a hair clip can be manufactured as follows. That is, first, a band 15 made of synthetic resin as shown in FIG. 9 is molded by a molding die (not shown). The formed band-shaped body 15 has an elastic bent portion 16 in a shape obtained by bending a plate body into a substantially V shape (the elastic bent portion 16 further extends outside both lateral sides 2 and 3 of the central elastic plate portion 1). And a pair of bending pieces 17 and 18 extending from the elastic bending portion 16 (each bending piece 17 and 18 is the leg portion). It has the same shape as 4, 5). Then, the elastic bending portion 16 of the molded strip 15 is pressed inward, and as shown in FIG. 10, the wide portions 17a and 18a of the bending pieces 17 and 18 (the wide portions of the hair holding portions 10 and 11 are widened). (Corresponding to the portions 10a and 11a) are crossed over each other, and the root portions 17b and 18b of the bending pieces 17 and 18 (corresponding to the root portions 8 and 9 of the leg portions 4 and 5) are crossed. Thereby, the hair clip shown in FIG. 1 can be produced.

When using this hair clip, as shown in FIG. 11, the outer side surfaces of the U-shaped lateral sides 2 and 3 of the central elastic plate portion 1 are pressed inward with fingers. As a result, the state in which the two leg portions 4 and 5 are in pressure contact with each other is separated and opened. At this time, when the central elastic plate portion 1 is fully pressed, the root portions 8 and 9 of both leg portions 4 and 5 hit the edge portions 2a and 3a of the U-shaped lateral sides 2 and 3 of the central elastic plate portion 1. . Next, the hair is sandwiched between the hair sandwiching portions 10 and 11 of both leg portions 4 and 5, and the pressing force of the fingers is released in that state. As a result, the leg portions 4 and 5 are closed by the outward biasing force of the central elastic plate portion 1, and the hair is pinched and fixed between the hair pinching portions 10 and 11.

As described above, in the hair clip of this embodiment, the conventional spring 23 can be omitted, and the cost is low. Moreover, it is composed of one part, has a simple structure, and simplifies management aspects such as inventory management. Further, the elastic bending portion 16 of the band-shaped body (molded product) 15 shown in FIG. 9 is pressed inward and the bending pieces 17 and 18 can be crossed to assemble, which simplifies the assembling work. Further, since the anti-slip ridges 6 and 7 are juxtaposed on the outer surfaces (pressing surfaces) of both lateral sides 2 and 3 of the central elastic plate portion 1, the central elastic plate portion 1 is directed inward with fingers. Fingers do not slip when pressed. Further, since the non-slip ridges 12 and 13 are juxtaposed on the hair holding surfaces of the both hair holding portions 10 and 11, the hair clip can be firmly fixed to the hair. Further, the root portions 8 and 9 of the leg portions 4 and 5 can be received by the edge portions 2a and 3a of the lateral sides 2 and 3 of the central elastic plate portion 1, respectively, and the leg portions 4 and 5 can be prevented from being damaged. become. Moreover, since the phases of the root portions 8 and 9 are shifted in the width direction of the lateral sides 2 and 3, the leg portions 4 and 5 do not collide with each other when the inward pressing is performed.

In the above embodiment, the clip of the present invention is applied to a hair clip used in the field of hairdressing and beauty, but the present invention is not limited to this, and clips for office and household use (paper scissors). , And also includes scissors such as clothespins), and can be applied to clips in various fields.
