Description

[Detailed Description of the Invention] The present invention is a proposal for a file that is made up of a large number of bag-shaped document storage bodies bound together, and that allows the storage bodies to be easily increased/decreased and attached/detached.

2. Description of the Related Art Files for storing documents such as drawings are made by binding bag-like storage bodies made of transparent sheets of synthetic resin.

This type of file has an opening at the top or side of the container, through which documents can be inserted and removed, and documents inserted into the container can be seen from either the front or the back. ing.

However, since most of these storage bodies are bound together with files, there are disadvantages in that the number of sheets is limited to a certain number and that the storage bodies cannot be taken out individually.

On the other hand, there are also files whose storage bodies can be attached and removed individually, but such files can be made by attaching binding metal fittings to the base of the storage body or inserting a binding string through holes drilled in the base of the storage body. Since it is bound, it has the disadvantage that it takes a lot of time and effort to put on and take off.

In the present invention, the base of the binding piece, which has a hook part on the lower surface and a receiver part on the upper surface, is fixed to both ends of the front opening of the storage body, and the receiver in which the hook part of the storage body intervenes is fixed. By providing the pieces on the inner surface of the back plate of the file cover, a file is provided that does not have the above-mentioned disadvantages.

To explain the file according to the illustrated embodiment below, 1 is a flat bag-shaped storage body made of a transparent synthetic resin sheet with a narrow opening 2 formed at the front end, and a narrow opening 2 formed at the front end. A synthetic resin binding piece 3 whose base portion is fixed to the storage body 1 is provided.

The binding piece 3 has a hook-shaped hook portion 4 formed on its lower surface, and a pocket-shaped receiver portion 5 that engages with the hook portion on its upper surface. The receiving part 4 of the upper storing body intervenes in the receiving part 5 of the storing body, so that the storing bodies are successively bound together.

Reference numeral 6 denotes a file cover, in which a back plate 7 consisting of two strip-shaped side plates 8, 8 that can be freely unfolded is provided in the center, and a synthetic resin sheet covering the storage body is provided at the outer end of each side plate in the longitudinal direction. The pocket-shaped receiver has the pieces 9 along with it and the hooks 4 of the binding piece 3 engage with the inner surfaces of both ends of one side plate 8, and the pieces 10 are fixed thereto.

Since the present invention is constructed as described above, in the case of the first storage unit 1, the receiver of the back plate 7 of the file cover 6 is first inserted into the piece 10.

Then, the next storage body is superimposed on top of that, and when the hook part 4 of the upper storage body is inserted into the catch part 5 of the binding piece 3 of the lower storage body, they are superposed one after another.

In addition, in order to remove the storage body, the hook part 4 of the binding piece in the upper storage body can be taken out from the receiver part 5 of the lower storage body.

Even if the storage unit is reversed, the hanging part 4 is interposed in the receiving part 5, so it will not escape and the storage units can be opened and closed mutually in the form of a two-page spread. Even if it is inserted across drawing 11, etc., there will be no inconvenience.

In other words, in the present invention, it is extremely easy to attach and remove each storage body, so anyone can insert and remove the storage bodies without the hassle of conventional methods, and since the required amount of storage bodies can be attached at will, it is possible to store a large number of documents. It is very convenient for filing documents, and it is also convenient to be able to insert and remove documents from each storage unit.

However, the present invention does not require the use of binding metal fittings or binding strings to insert and remove the storage body from the file cover, and is extremely easy to handle, has good workability, and has a simple structure, so it has the practical benefit of being suitable for low-cost mass production.

Note that the bag-like storage body 1 according to the present invention may have an opening not only at the front end but also at both side ends and the rear end, or may have a structure in which the opening can be opened and closed, and is not limited to the structure.
