Description

[Detailed description of the invention] (Industrial application field) This invention relates to a binding tool used for binding pieces of paper, etc.

(Prior art) Conventionally, this type of binding tool was used, for example, in 15286
As described in the publication, an operating lever is swingably supported on a shaft attached to a base, and a bullet having a pair of legs is supported on the shaft. One leg of the ammunition is engaged with the operating lever, and the other leg supports a clamping plate facing the horizontal surface of the base, while the lever is placed between the base and the operating lever. An engaging means is provided for engaging the base with the base.

When binding pieces of paper into the binding tool, the engaging means is released by operating the operating lever, and the clamping plate is spaced upward from the base, so that the gap between the base and the clamping plate is removed. Insert a piece of paper into the holder, and then push down the operating lever to engage the lever with the base using the engaging means, thereby applying a pressing force toward the base to the clamping plate via the elastic device. The paper strips are attached so that the pieces of paper are elastically bound between the clamping plate and the base.

(Problem to be solved by the invention) However, in the conventional binding device, since one bullet applies a pressing force to the clamping plate toward the base, the clamping plate and the base When a large number of pieces of paper are inserted between the two, the pieces of paper sometimes come off from between the clamping plate and the base.

In solving the above problems,
It is conceivable that the wire diameter of the bullet be made large so that the pressing force of the bullet against the clamping plate is strong.
In this case, the pressing force of the bullet is concentrated on the bullet supporting portions of the base and the clamping plate when paper pieces are bound, and therefore it is necessary to increase the strength of the base and clamping plate, and the weight is reduced. In addition, when a conventional clamping plate is used, both sides of the clamping plate around the ammunition support part are bent, and the clamping plate The pressing force of the holding plate is concentrated on a portion of the paper piece without applying pressure to the paper piece as a whole, and the paper piece becomes easy to move, leading to separation of the paper piece. .

The present invention was devised in view of the various problems mentioned above, and by using two bullets and applying pressing force to the clamping plate as a whole with each bullet, the base plate and the clamping plate are It is an object of the present invention to provide a binding tool that can securely and firmly bind paper pieces without separating them between the clamping plate and the base without particularly increasing the strength of the paper.

(Means for Solving the Problems) The configuration of the present invention is to support a pair of first and second shaft rods on a base along the length direction of the base, and to An operation in which a sliding groove extending in the length direction is provided on one side in the width direction in a first shaft rod located on the outside in the length direction of the base, and a means for engaging the base is provided on the tip side. The lever is pivotally supported, and the first lever is pivotably supported.
and a second shaft supporting first and second ammunition aircraft each having a pair of legs, and one leg of each of these aircraft supporting a clamping plate facing the horizontal surface of the base. On the other hand, the other leg of the first ammunition aircraft supported on the first shaft is engaged with the lever, and the other leg of the second ammunition aircraft supported on the second shaft is engaged with the lever. It was made to freely slide into engagement with the sliding groove.

(Function) When inserting a piece of paper between the base and the clamping plate, the engaging means is released by operating the operating lever, and the clamping plate is held apart from the base; After inserting a piece of paper between the base and the clamping plate, the operating lever is pushed toward the base against each of the bullets and engaged by the engaging means, so that each of the bullets is engaged. The pressing force can be distributed and applied to the clamping plate as a whole, and the paper pieces can be firmly and strongly bound between the clamping plate and the base without increasing the strength of the base plate and the clamping plate. It was very complicated.
