DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file, and more particularly, to a file in which a binding device is attached to a back cover of a cover body in which a front cover and a back cover are connected to a back cover via a hinge portion.

[0002]

2. Description of the Related Art In general, a file in which a binding device comprising a board, a standing wall having a binding rod standing upright on both sides in the width direction of the board, and a lock plate is attached to the inner surface of a spine. As disclosed in Japanese Utility Model Laid-Open Publication No. 2-117187, two hinge portions are provided at the center in the longitudinal direction of a cover body mainly made of one sheet of thick paper, and the spine cover is provided between these hinge portions. As described above, the binding device is attached to the inner surface of the spine, the front cover and the back cover are opened, and a leaf is bound to the binding device, and after binding the leaf, the front cover and the back cover are attached. Are closed so that they face each other on both sides in the width direction of the binding device, and are stored standing on a filing shelf or the like.

[0003]

However, the file constructed as described above has a wide backstrip so that a large number of paper sheets can be bound therein. In many cases, the thickness of the cardboard is increased so as to obtain the strength at the time of standing storage.

When a hinge is formed on the cover body thus configured, the cover is formed by pressing the cover body from the outer surface to the inner surface in a concave shape, and these hinge portions protrude inward. It has a shape that swells like this. For this reason, the front cover and the back cover can be opened and folded or closed in a folded state with respect to the spine, but when closed in a folded state, the hinge portion having a shape protruding inward is closed. The bulging portion is elastically deformed in a compressed state. Therefore, when the front cover and the back cover are closed in a folded manner, the reaction force due to the elastic deformation of the hinge portion acts on the front cover and the back cover in the opening direction, and the reaction force of the hinge portion causes the reaction between the front cover and the back cover. The cover will spread, and it will not only look bad when placed on a desk etc.,
There was also a problem taking place.

The cover body may be formed of a thick synthetic resin sheet in addition to the thick paper as described above, and a hinge portion is formed on the cover body made of the synthetic resin sheet. In this case, the inner surface of the cover body is formed into a thin shape by providing a concave streak recessed toward the outer surface. For this reason, when closing the front cover and the back cover with respect to the spine, the hinge portion is bent and twisted from the expanded state to the upright state, so that the thin portion is elastically deformed. When the front cover and the back cover are closed in a folded manner, the reaction force due to the elastic deformation of the hinge acts on the front and back covers in the opening direction, and as in the case where the cover body is formed of thick paper, the hinge is closed. The closed front cover and the back cover spread due to the reaction force of the part.

An object of the present invention is to prevent the front cover and the back cover from spreading due to the reaction force of the hinge portion when the front cover and the back cover are closed in a folded manner, and to close the front cover and the back cover in parallel. The point is to be able to do it.
