Embodiments of the present invention will be described below with reference to the drawings.

First, the structure of the binding tool will be described. FIG.
In FIG. 2, reference numeral 1 denotes a binder main body made of synthetic resin, and the binder main body 1 is a support body 2 including a pair of support plates 2a and 2b.
And a plurality of annular binding rings 3 provided upright on the support 2 at a predetermined interval.

The support plates 2a and 2b are formed in an extremely thin plate shape,
On one of the support plates 2a, a convex portion 4a is projectingly provided at the central portion in the longitudinal direction of the joint surface with the other support plate 2b, and on the joint surface of the other support plate 2b at a position corresponding to the convex portion 4a. The recess 4b is formed,
By fitting the uneven portions 4a, 4b, both supporting plates 2a, 2b
Are stacked and joined together.

As shown in FIG. 2, the binding ring 3 comprises a pair of arcuate binding claws 3a and 3b, which are attached to one support plate 2a and the other support plate 2b. The binding claw 3b is a protrusion formed on the tip of one binding claw 3b.
5a is engaged with a recess 5b formed at the tip of the other binding claw 3b to form an annular shape. Further, one binding claw 3a is formed in an arc shape longer than the other binding claw 3b.

Next, a method of binding the sheet body by using the sheet body binding tool having the above-mentioned structure will be described.

First, as shown in FIG. 3, the supporting plates 2a and 2b are slid in the longitudinal direction to release the fitting of the concave and convex portions 4a and 4b and separate them. At this time, the engagement of the binding claws 3a and 3b is also released, and the binding tool body 1 is divided into two.

Next, the sheet body 6 to be bound by the binding tool is prepared. The sheet body 6 is a notebook paper sheet having holes 7 formed at its ends at the same intervals as the binding claws 3a and 3b and having a diameter such that the binding claws 3a and 3b can be inserted therethrough.

As shown in FIG. 4, such a sheet body 6 is formed by inserting the tip of one binding claw 3a into the hole 7 and binding the claw.
It is attached to 3a and rotated to above the support plate 2a. Similarly, in the other binding claw 3b, a sheet body 6a serving as another back cover is inserted from the tip of the binding claw 3b and rotated to the side of the support plate 2b.

After all the necessary sheet bodies 6 have been attached to the binding claws 3a and 3b, the support plates 2a and 2b are fixed again by engaging the convex portions 4a and the concave portions 4b, and fixing the binding claws 3a and 3b. A sheet file body 8 as shown in FIG. 5, which is bound by a binding tool, is formed by also locking the leading end portion to form an annular shape.

The sheet file body 8 includes support plates 2a and 2b.
Is located immediately inside the back cover sheet body 6a, and only the binding claws 3a and 3b are exposed at the position corresponding to the spine cover of the sheet file body 8.

Further, since the one binding claw 3a is longer than the other binding claw 3b, the joint portion between the two binding claws 3a and 3b is located on the back side of the sheet file body 8, and the binding claws 3a and 3b from the front cover side. I can't see the joint.

When such a sheet file body 8 is used as a notebook, as shown in FIG. 6, an object for preventing the opening of the sheet body 6 such as the supporting plates 2a and 2b on the spine side of the opened notebook. Since there is no sheet, the bound sheet body 6 can be completely opened, and the edge portion of the sheet body 6 does not rise so much. For example, necessary information is written in this portion or the edge portion is written. You can easily read matters.

When an additional sheet body is inserted between the sheet bodies 6, the notebook is rolled to the position where the sheet body is to be inserted, and the support plates 2a and 2b are slid and separated, and the additional sheet body is bound to one side. Insert it from the tip of the claw 3a and re-support plate 2
The sheet body 6 can be easily added by fixing the a and 2b. On the contrary, when one sheet is taken out from the already bound notebook, it can be easily taken out by dividing the binder body 1 in the same manner.

Further, since the supporting plates 2a, 2b are located immediately inside the sheet body 6a of the back cover of the notebook, that is, behind the last page of the notebook, there is no hindrance during use, and the supporting plates 2a, 2b. Since it is hard to see, it does not spoil the appearance of the notebook.

In the above embodiment, as a method of fixing the support plates 2a and 2b, the support plates 2a and 2b are joined and the uneven portions 4a and 4b formed on the joint surface are engaged and fixed. Support plates 2a, 2b
The fastening method is not limited to this, and may be fastened by other fastening means such as a magnet or a button.

Further, in the above embodiment, when the support plates 2a and 2b are attached and detached, the support plates 2a and 2b are slid in the longitudinal direction and attached to and detached from each other. However, as shown in FIG. ,
Both support plates 2a and 2b may be detachably formed by vertically rotating one support plate 2a on the upper surface. In addition to this, a detachable means that opens and closes in a fan shape in the horizontal direction may be used, and in short, any detachable means may be provided as long as the two support plates 2a and 2b are detachably joined.

Further, in the above-mentioned embodiment, the concavo-convex portions 5a and 5b are formed on the joint surface at the tips of the binding claws 3a and 3b, and the concavities and convexities 5a and 5b are fitted to the tips of the binding claws 3a and 3b. Although the parts are connected, such a connection is not a condition, and for example, only the tips of the binding claws 3a and 3b may be joined, and further, the tips that are fitted to each other as shown in FIG. 7B. But it's okay. In particular, when the support plates 2a and 2b are detachably formed by rotating one of the support plates 2a in the vertical direction as described above, they are fitted in the vertical direction as shown in FIG. 7B. If it is formed at the tip like this, one support plate 2a
Can be easily moved by moving the binding claws 3a, 3a
There is an advantage that the tip of b can be attached and detached. Further, in this case, it is preferable that the tip ends of the binding claws 3a and 3b are connected to each other on the upper surface of the binding tool.

However, the point is that the pair of binding claws 3a and 3b are connected to each other at their leading ends and formed into an endless ring shape so that the sheet body 6 does not fall out, and the connecting means of the leading ends of the binding claws 3a and 3b. Is not limited.

Further, in the above embodiment, the binding claws 3a and 3b are formed in an arc shape in which one of the binding claws 3a is longer than the other binding claw 3b, but the binding claws formed in a semi-arc shape have the same length. 3
The binding ring 3 composed of a and 3b may be used. However, when one binding claw 3a has an arc shape longer than the other binding claw 3b as in the above embodiment, the connecting portion of both binding claws 3a, 3b is attached to one of the spine covers of the sheet file body 8. Since they are located in a biased position, the connecting portion cannot be seen from the front cover side, which is advantageous in that the sheet file body 8 looks good. Further, it is not always necessary that the binding claw has an arc shape, and for example, as shown in FIG. 8, the binding claw in which the position corresponding to the spine cover side is linearly formed
It may be 3a, 3b. In this case, there is an advantage that the opening of the sheet body 6 is further improved.

Further, the widths of the support plates 2a and 2b are such that they do not interfere with the use of the file body, and the binding claws are used.
The width is not particularly limited as long as 3a and 3b can be attached, and the thickness of the support plates 2a and 2b is also not particularly limited. However, if the support plates 2a and 2b are thick,
Since it is bulky and difficult to use when sandwiched between the sheet bodies 6, it is desirable that the sheet body be formed as thin as possible.

In the above embodiment, the support plates 2a, 2b are formed so as to be located immediately inside the sheet body 6a of the back cover of the sheet file body 8. The sheet body 6 may be bound as described above. However, when the support plates 2a and 2b are formed so as to be located immediately inside the sheet body 6a of the back cover of the sheet file body 8,
There is an advantage that the support plates 2a and 2b do not get in the way when the sheet file body 8 is used and the support plates 2a and 2b are located on the back side, so that the appearance is good.

Further, although the binder main body 1 made of synthetic resin is used in the above embodiment, the material of the binder main body 1 is not limited to this, and other materials such as metal may be used. Good.

In the above embodiment, note paper is used as the sheet 6, but the sheet to be bound by the binding tool of the present invention may be other than paper. Further, the bound sheet file body 8 is used as a notebook in the above embodiment, but the sheet file body may be used for any purpose other than the notebook, such as organizing materials, address book, memo pad, etc. Good.
