Abstract

PROBLEM TO BE SOLVED: To make a molding mold simple by a paper pinching clip composed of two pinching plates and to facilitate assembling work. SOLUTION: The two pinching plates are made moldings of the same shape, a hole is formed in one of the sleeve parts formed in the pinching plate, and a projection conforming to the hole is formed in the other sleeve part. The plates are combined by inserting the projections into the holes mutually between the plates, the bent part of a U-shaped spring is located between the sleeve parts of the combined plates and inserted between the plates, and the plates are biased in the closing direction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper-clamp clip of the type in which two clamp plates are joined.

[0002]

2. Description of the Related Art A conventional paper clip has a structure in which sleeves of two clamping plates are aligned with each other, a shaft pin is passed through, and both clamping plates are connected, and a coil spring is wound around the shaft pin. The number of parts was large, and assembly was troublesome. In particular, the two sandwiching plates have a structure in which the two sleeves of the other sandwiching plate are positioned inside the sleeves provided on one of the sandwiching plates, thereby preventing lateral displacement between the two sandwiching plates. The two sandwich plates were not the same shape, and the spacing between both sleeves was different. In addition, the assembly work is troublesome because the coil spring is wound around the shaft pin.

It is to be noted that a proposal for making the two sandwich plates the same shape is disclosed in, for example, Japanese Utility Model Publication No. Sho 61-30636 (utility model registration No. 1678).
No. 152) and the like, but in such a case, the two sandwiching plates are faced so as to be separable, the spring to be closed by itself is forcibly expanded and attached from the outside of the two sandwiching plates.
Since the two sandwiching plates are connected, the two sandwiching plates are unstable during assembly, and a spring is forcibly mounted on the two sandwiching plates, which causes a problem that the assembling operation is difficult.

[0004]

As described above, since the conventional paper clip has a large number of parts and is cumbersome to assemble, the present invention aims at reducing the number of parts and facilitating the assembly. is there.

[0005]

The manufacturing cost is reduced by molding two sandwich plates into the same shape. In each sandwich plate, a hole is formed in one of a pair of sleeves which are opposed to each other, and the other hole is formed in the other. A projection is formed at a position corresponding to, and both of the sandwiching plates are combined, and the projection of the sleeve of one of the sandwiching plates is fitted into the hole of the sleeve of the other sandwiching plate. The two sandwiching plates are openably and closably connected with each other as an axis, and a U-shaped leaf spring or a coil spring is inserted between the sleeves of the two sandwiching plates and is mounted between the two sandwiching plates.

[0006]

FIG. 1 shows an example of an embodiment of the present invention. FIG. 1 shows an exploded view, and reference numerals 1 and 1 'denote sandwich plates, which are molded products of synthetic resin, are formed by the same mold, and have exactly the same shape. In FIG. 1, the sandwiching plate 7 'shows only both sleeves except for the main part. A pair of sleeve portions 2 and 3 are formed integrally with the sandwiching plates 1 and 1 'so as to oppose each other. A hole 4 is formed in the sleeve 2. The other sleeve 3 has a hole 4 outwardly at a position corresponding to the hole of the sleeve 2.
Is formed. The sleeve 2 has a base thickness of about twice the thickness of the base of the sleeve 3, and is formed into a circle 6 centering on the hole 4 and conforming to the head of the sleeve 3, The thickness of this section is the same as the thickness of the sleeve 3. Reference numeral 7 denotes a U-shaped leaf spring whose ends are slightly open. 7 'is a coil spring in another example.

With the two sandwiching plates 1, 1 'facing each other with their sleeves facing each other, the sleeve 3 on the side with the projections 5 is positioned between a pair of sleeves of the other party, and one projection is formed. When 5 is fitted into the hole of the sleeve of the other sandwiching plate, the sandwiching plates 1 and 1 'are openably and closably connected with the projection 5 as a fulcrum. As shown in FIG. 2, between the two sandwiching plates 1, 1 'thus joined,
The U-shaped leaf spring 7 or the coil spring 7 'is inserted between the sleeves 2 and 3 with the bent portion facing the front end of the sandwiching plate, and both ends are sandwiched between the rear ends of the sandwiching plates 1 and 1'. The clip is completed by being locked to the locking projections 8, 8 'on the inner surface. Since these springs are interposed between the sleeve portions of the sandwiching plates and act as spacers, lateral displacement of the sandwiching plates can be prevented.

[0008]

According to the clip of the present invention, it is needless to say that the manufacturing cost can be reduced because the two sandwiching plates have the same shape.
With a structure in which two sandwiching plates are fitted in advance so that they can be opened and closed,
It is connected before installing the spring, and the spring only needs to be pushed between the two sandwich plates, so while holding the two sandwich plates so as not to separate, forcibly expand the spring that is going to close by itself, The assembly work is remarkably easy compared with the conventional one which is mounted from the outside of the sandwiching plate, and the manufacturing cost of the clip is also reduced in this respect.

Claims (1)

[Claims] 1. A paper clip having a shape formed by combining two sandwich plates, wherein both sandwich plates have the same shape, a pair of sleeves are erected for each sandwich plate, and a hole is formed in one sleeve. The other sleeve is provided with a projection, and the two sandwiching plates are combined so that the upstanding sleeves are alternately arranged, and the projection of the other sandwiching plate is inserted into the hole of the sleeve of the one sandwiching plate. Characterized in that a U-shaped leaf spring or a coil spring is mounted between both of the sandwiching plates by interposing between the pair of sleeves.
