Description

[Detailed description of the invention] (Field of industrial application) This invention is a binding device, specifically, a base plate having a first side plate that stands up on one side in the width direction, and a rocking device that is supported so as to be tiltable with respect to the base plate. a plate, a cylindrical first binding rod attached to the swing plate, a presser body having a second binding rod insertable into the first binding rod, and the presser body at a position inside the first side plate. The present invention relates to a binding device having a locking font that locks.

(Prior Art) Conventionally, this type of binding tool includes the substrate, a first side plate,
Components such as the first and second spelling rods, the swing plate, and the lock body are each made of metal members, and the swing plate is formed to have approximately the same height as the upright height of the first side plate, This swing plate is tiltably supported by the base plate via a pivot pin.

(Problems to be solved by the invention) However, in the above-mentioned binding tools, since the various component parts of the binding tools are made of metal members,
When the pieces of paper bound in the binding tool become unnecessary and are incinerated while still bound in the binding tool, the binding tool remains bulky without being incinerated. When incinerating the paper, it was necessary to take the trouble to remove the piece of paper from the binding tool and incinerate it.

Therefore, in order to solve the above problems,
By forming the various component parts of the binding tool out of synthetic resin and making the binding tool burnable, the idea was to incinerate the binding tool as a whole with the pieces of paper still bound. .

That is, as shown in FIG. 12, the binding tool includes a base plate 1 having a first side plate 2 standing upright on one side in the width direction, and a swing plate 5 supported so as to be tiltable with respect to the base plate 1. , a cylindrical first tube attached to this swing plate 5
Consisting of a binding rod 4, a presser body 7 having a second binding rod 8 that can be inserted into the first binding rod 4, and a locking body 6 that locks the presser body 7 at a position inside the first side plate 2. However, the base plate 1, the first side plate 2, the first binding rod 4, the rocking plate 5, and the lock body 6 are each integrally formed of a synthetic resin that can be incinerated.

By the way, when the various components mentioned above are integrally formed from synthetic resin, like conventional binding tools,
When the height of the rocking plate 5 is the same as the upright height of the first side plate 2, the length from the tilting fulcrum to the free end of the rocking plate 5 becomes longer, and the rocking plate 5 becomes longer. When external pressure is applied to the oscillating plate 5 made of synthetic resin, it easily bends and deforms the binding tool, and as a result of this deformation, the locking body 6 and presser body 7 are disengaged from each other. This causes problems such as the bound pieces of paper coming off.

Therefore, when the binding tool is made of synthetic resin, as shown in the same figure, there is a metal plate on the other side in the width direction of the substrate 1, which faces the first side plate 2 and has a lower standing height than the first side plate 2. The second side plate 3 is made to stand up integrally, and the swing plate 5 having the first spelling rod 4 is attached to the hinge portion H at the tip end edge of the second side plate 3 in the standing direction.
In this way, the rocking plate 5 is shortened by the length of the second side plate 3, which reduces deflection due to external pressure, and solves the above-mentioned problem. be.

However, when using the above structure, when a piece of paper is bound to the binding tool, the locking body 6 and the presser body 7 are unlocked, and the swinging plate 5 is moved against the second side plate 3. When swinging outward about the hinge H, since the swing plate 5 is biased in the upright direction by the hinge H, the swing plate 5 is collapsed horizontally. In other words, the first spelling rod 4 provided on the swing plate 5
There was a problem in that it was difficult to stand up vertically, making it difficult to bind pieces of paper to the binding rod 4.

The present invention has been devised in view of the above-mentioned problems, and its purpose is to constantly bias the rocking plate in an outward tilting direction with respect to the second side plate through a spring, so that the lock body When the presser foot is unlocked, the rocking plate is automatically tilted outward via the spring, thereby making it possible to easily bind the pieces of paper and to prevent deformation of the overall shape. To provide a binding tool which can securely bind paper pieces without causing damage and can incinerate the entire paper pieces in a state in which they are bound.

(Means for Solving the Problems) As shown in the embodiments of the drawings, the present invention includes a substrate 1 having a first side plate 2 standing upright on one side in the width direction;
A rocking plate 5 tiltably supported with respect to the substrate 1
and a cylindrical first spelling rod 4 attached to this swing plate 5.
A binding tool consisting of a presser body 7 having a second binding rod 8 that can be inserted into the first binding rod 4, and a locking body 6 that locks the presser body 7 at a position inside the first side plate 2. A second side plate 3 that faces the first side plate 2 and has a lower standing height than the first side plate 2 is erected on the other side of the substrate 1 in the width direction.
A rocking plate 5 having the first spelling rod 4 is supported on the tip edge in the upright direction so as to be tiltable outward, and
The base plate 1, each of the side plates 2 and 3, the first binding rod 4, the swing plate 5, and the lock body 6 are integrally formed of synthetic resin, and there is a space between the base plate 1 side and the swing plate 5 side. , is characterized in that a spring 10 is provided which always biases the swing plate 5 so as to tilt it outward.

(Function) However, since most of the component parts of the binding tool constructed as described above are made of synthetic resin, the entire binding tool can be incinerated with the pieces of paper still bound in the binding tool. , and the rocking plate 5 is mounted on a second side plate having a lower standing height than the first side plate 2.
Because it is tiltably supported via the side plate 3,
The deflection of the rocking plate 5 due to external pressure can be reduced, and it is possible to prevent the pieces of paper bound to the binding device from coming off. Since the second side plate 3 is always biased in the tilting direction, when the lock body 6 and the presser body 7 are unlocked, the swing plate 5 moves outward via the spring 10. Since it is automatically tilted to the side, it is possible to easily bind pieces of paper to the first binding rod 4 provided on the swing plate 5.
