Abstract

PURPOSE:To avoid causing damage even relative to paper which is susceptible to scratches by providing a spring receiving piece on the part for receiving one spring of a paper holder board and by varying the distance from the rotating shaft of the holder board to the spring receiving piece and thereby changing the compressive angle. CONSTITUTION:A holder board 1 and a holder board 2 are movably combined by means of a shaft 3 and one end of a coil spring 4 being passed through the shaft 3 is in contact with the inner wall of the board 2 and the other end thereof is in contact with a spring receiving piece 5 with pressure. The spring receiving piece 5 is retained in a plurality of holes made on the holder board 1 and a series of holes made by connecting distances between the holes with a straight line groove. In this variable spring pressure type clip, when the spring receiving piece 5 is set in the proximity of the shaft 3 through the operation of a knob, the compressive angle theta1 of the coil spring 4 may be small and the pressure of the clip thus may become large. On the contrary, when the spring receiving piece 5 is set apart from the shaft 3, the compressive angel theta2 of the coil spring 4 may be large and the compression of the clip may thus become small. Namely, by shifting the receiving piece 5 provided on the holder board 1, clipping pressure can be variable therebetween.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable spring pressure type clip for binding a plurality of sheets of paper.

[0002]

2. Description of the Related Art Conventional clips have a constant pressure when the thickness of a bundle of papers is constant.

[0003]

However, the conventional clip has a problem that the paper is damaged due to the clip mark due to the quality of the paper, and especially when a thick one is sandwiched.

The present invention is intended to solve such a conventional problem, and an object thereof is to provide an excellent clip which is not damaged even on paper which is easily damaged.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a spring receiver at a portion of a sandwich plate that sandwiches paper to receive one spring, and the spring receiver from the rotary shaft of the sandwich plate. The compression angle of the spring is changed by changing the distance to.

[0006]

By changing the position of the spring receiver, the compression angle of the spring is changed, and the pressure for pinching the paper can be changed, and the paper can be pinched without damaging the paper by the adjustment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.

FIG. 1A is a perspective view showing the structure of an embodiment of a variable spring pressure type clip of the present invention, and FIG. 1B is an exploded view showing the structure of a spring receiver in the structure of the embodiment of the present invention. 2 is a side view for explaining the function of the spring receiver, FIG.
(A) shows the case where the spring receiver is close to the shaft, and (b) shows the case where it is far.

In FIG. 1A, the sandwiching plate A1 and the sandwiching plate B2 are movably connected by a shaft 3. One end of the coil spring 4 penetrating the shaft 3 is in contact with the inner wall of the sandwiching plate B2, and the other end is in contact with the spring receiver 5 with pressure. The spring receiver 5 is held by a plurality of round holes formed in the sandwiching plate A1 and a skewer dumpling-like hole 6 formed by connecting the round holes with straight grooves. In FIG. 1B, 7 is a knob, which is a T-shaped plate, which also serves as a shaft. The washer 8, the hole 6 of the sandwiching plate A1 and the spring receiver 5 are fitted into the shaft portion of the knob 7, and the notch 9 provided at the tip of the shaft portion of the knob 7 is opened to prevent the knob 7 from coming off. The shaft portion and the splash receiver 5 are rotatable. When one knob 7 is horizontal in one of the skewer-shaped holes 6, it is fixed to the hole when it is horizontal, but when knob 7 is turned vertically, it moves along the straight groove to the other hole. Can be made.

In the variable spring pressure type clip constructed as described above, the spring receiver 5 is moved to the shaft 3 by operating the knob 7.
2A, the compression angle θ1 of the coil spring 4 is small and the pressure of the clip is large. Further, when the spring receiver 5 is set far from the axis 3, as shown in FIG.
Is large and the pressure of the clip is small. That is, the clip pressure can be changed by moving the spring receiver 5 provided on the sandwich plate A1.

[0011]

As described above, according to the present invention, the two sandwiching plates A and B which are rotatable within a limited range around the shaft and the winding start and winding end portions of the coil are the circles of the coil. In a clip composed of a coil spring formed so as to extend in the radial direction, the holding angle of one end of the coil spring is sandwiched by plate A
By changing the position of the spring receiver on the hole, it is possible to realize an excellent variable spring pressure type clip that can change the clip pressure.
