Abstract

(57) [Summary] [PROBLEMS] To increase the paper holding force of a ZEM clip. SOLUTION: In a zem clip in which a wire is spirally bent, a corrugated bend is given to an adjacent parallel wire. As a result, the sandwiched paper is deformed to conform to the waveform, and the paper does not fall off.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a business-use paper clip of a type in which a wire such as a wire or a plastic wire is bent without any intersection.

[0002]

[Prior art]

 The conventional zemclip is formed by bending a line with a smooth surface, so that the sandwiched paper is easy to slip and the force for keeping the papers together is weak, and the paper may fall off. For this reason, some large gem clips try to cut the striations into fine stripes to prevent slippage, but the zem clips sandwich the paper only between the adjacent inner and outer filaments. However, since the horizontal stripes were carved only on the front and back surfaces of the filaments, not on the front and back surfaces of the filaments, there was almost no anti-slip effect.

[0003]

[Problems to be solved by the invention]

 The purpose of the present invention is to solve the drawback that the paper clip has a weak gripping force and is slippery by a simple method.

[0004]

[Means to solve the problem]

 In a zem clip in which the filaments were spirally bent, a wavy bend was given to the part where the inner and outer filaments were adjacent and parallel.

[0005]

[Embodiment of the invention]

 FIG. 1 shows an example of an embodiment of the present invention. Reference numeral 1 denotes a wire which is bent in an oval spiral shape in which two parallel side portions 1a and 1b are connected by a semicircular portion. In this gem clip, the two side portions 1a and 1b respectively have the outer winding portion and the inner winding portion of the spiral wire in parallel contact with each other. As shown in the figure, wavy irregularities (bends) 2 are formed in the line portions in parallel contact with each other in the direction perpendicular to the spiral surface. The usage of the thus formed zemclip is exactly the same as a normal zemclip.

The formation of the wavy irregularities (bends) 2 of the above-described zem clip is performed as shown in FIG. P is a punch of a press machine, D is a die, and a wavy concave and convex groove V which is in mesh with each other is formed on the contact surface of both. By placing a normal-shaped zem clip Z having a smooth line wound between the punch and the die and operating the press machine, a zem clip as shown in FIG. 1 is formed. When the wavy bend is given to the parallel sides of the gem clip in this way, the length of the gem clip is reduced, and therefore, the gem clip is previously formed into a slightly longer turn.

In the present invention, in the case of bending in a wave shape, the number of waves is not limited to three as shown in FIG. 1, but may be one, or may be more than three. Further, the plane shape of the gem clip is not limited to a normal elliptical shape having two parallel sides, but may be a circular shape or an elliptical shape as shown in FIG.

FIG. 4 shows another embodiment of the present invention, in which the corrugation is formed outward or inward within the turning plane of the zem clip. This waveform is effective for only one of the two parallel sides of the zem clip, not both. Only one is advantageous in manufacturing. FIG. 5 shows an example of a method of forming a waveform on only one side. The die D has an overhang D1 that can be inserted into the inner periphery of the gem clip, and has a groove V formed on the upper surface. The clip Z is fitted to the overhang, and the punch P is knocked down from above. At this time, two adjacent filaments forming one side of the zemclip are arranged in a direction perpendicular to the spiral surface of the zemclip by the pressing force of the punch, and each of them is bent into the same shape by the bending action. It becomes a clip like this.

[0009]

[Effect of the invention]

 The paper of the present invention has the above-described structure, and the paper sandwiched between the wavy lines of the paper of the paper is deformed finely in an attempt to blend in.Therefore, when the paper is to be removed, the paper deformation must move. However, because the paper does not fit perfectly, the opening of the clip becomes larger than in the case where the paper clip is smooth, and the pressing force due to elasticity increases. This makes it difficult for the paper to fall off. On the other hand, since the lines forming the gem clip are given a wave-like deformation, they can be easily hooked on the finger when the gem is pulled out.
