Abstract

PROBLEM TO BE SOLVED: To prevent the occurrence of disengagement of a lever arm provided on a clip from a shaft when the lever arm is strongly pulled while being rotated to a right-angle position. SOLUTION: A lever arm 1 formed by bending a hard steel wire such that a pinching portion 5 is formed at one end of the lever arm, while a fitting portion 3 is formed at the other end thereof is put in a state in which a gap portion 4 constituting a mating surface of ends of the hard steel wire is provided in such a manner that the gap portion 4 laterally faces relative to the pinching portion 5. This lever arm 1 is constructed such that a pulling force directed away from a shaft does not directly act on the gap portion 4 but on a bent portion of the fitting portion 3 so as to prevent the disengagement of the lever arm 1 from the shaft 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double clip lever arm used for holding documents and the like.

[0002]

2. Description of the Related Art A lever arm of a conventional double clip has a holding tool which rotates between a right angle position and a parallel position about a shaft provided between a holding piece and a parallel plate.
No. 8950.

[0003]

In such a conventional clip, when the lever arm is rotated between a right angle position and a parallel position, and the lever arm is pulled to the right angle position, the force acts in a direction away from the center of the shaft body. The lever arm could come off the shaft. The reason that the lever arm comes off the shaft body is because the mating surface of the hard steel wire provided at the fitting portion of the lever arm is located directly below the knob portion, and the shaft body is moved from the mating surface. It is something that will break out. The problem to be solved by the present invention resides in how to take means for preventing the lever arm from coming off the shaft.

[0004]

According to the present invention, when the lever arm (1) is rotated between a right angle position and a parallel position, a pulling force is applied in a direction away from the center of the shaft body (2). 3)
Means that does not directly act on the gap (4) that is the mating surface of the hard steel wire, and the gap (4) is provided at a position that is lateral to the knob (5). Means. By making the gap (4) sideways in this way, the force pulling away from the center of the shaft acts on the curved hard steel wire of the fitting part (3). Therefore, since the lever arm is in the same state as the hook, the lever arm can be prevented from coming off even with a strong force.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a clip lever arm (1) according to the present invention, as shown in FIG. 1, one hard steel wire is bent to form a knob (5) at one end. At the other end, a fitting portion (3) is formed. The clip to which the lever arm (1) is attached is bent by an elastic plate so as to have a space, and a holding portion (7) is formed at a portion where the end of the holding piece (6) abuts. 6), a parallel plate (8) folded in parallel is formed. A shaft body (2) is provided between the holding piece (6) and the parallel plate (8), and the fitting portion (3) of the lever arm (1) is turned on the shaft body (2). To be fitted. In the fitting part (3) fitted to the shaft body (2), a gap between the mating surfaces where both ends of the hard steel wire face each other is defined as a gap part (4). The lever arm (1) is configured such that the gap (4) is provided at a position lying laterally toward the knob (5).

As the gap (4) provided in such a lever arm (1), in addition to the one in which both ends of the hard steel wire are cut off as shown in FIG. May be provided. It is also conceivable to make a folded ring (10) as shown in FIG.

When the fitting portion (3) provided with the lateral gap (4) is fitted to the shaft (2), the shaft (2)
When the fitting portion (3) is pushed into the shaft body (2) by pressing the gap portion (4) toward the shaft member (2), the gap portion (4) is fitted to the shaft body (2) by elasticity of expansion and return. That is, by pushing the lever arm (1) not in the vertical direction of the knob (5) and the fitting portion (3) but in the horizontal direction, the shaft body (2) is pushed.
It can be fitted in. When detaching, it can be detached from the shaft body (2) by pulling in the direction opposite to the direction in which the shaft body (2) was fitted.

In the lever arm according to the present invention, when the lever arm (1) is rotated between a right angle position and a parallel position, a force acting in a direction away from the center of the shaft body (2) is:
Since it acts not on the gap (4) of the lever arm (1) but on the portion curved in the hook state, the force for expanding the gap (4) cannot be expanded unless a very strong force is applied. . Therefore, the lever arm (1) does not come off the shaft body (2).

[0009]

In the clip to which the lever arm (1) according to the present invention is attached, when the lever arm (1) is rotated between the upright position and the parallel position, the lever arm (1) is rotated by the shaft body. Departure from (2) does not occur. Further, at any position, the lever arm (1) does not come off due to the pulling force in the longitudinal direction which is the longitudinal direction of the lever arm (1), and the lever arm (1) can be used with confidence.
