Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a file with a stopper that allows the width of a spine cover to be adjusted according to the thickness of sheets to be bound.

[0002]

[Prior art]

 When binding sheets to a file, the thickness of the sheets to be bound increases as the number of sheets to be bound increases, and various files have been proposed in which the width of the spine cover can be adjusted according to the thickness. Among them, for example, the files disclosed in Japanese Utility Model Laid-Open No. 63-18282, Japanese Patent Laid-Open No. 5-69693, or Japanese Patent Laid-Open No. 8-175065 include a front cover and a back cover on which a binding portion is formed. One of the covers is a bag cover with one end open, the other cover is integrated with the spine cover, and the spine cover is inserted in the bag cover bag. This file can slide the back cover and adjust the width of the back cover according to the thickness of the paper to be bound.

[0003]

[Problems to be solved by the device]

 In the above files, the back cover is only inserted into the bag cover, so the back cover can be easily removed from the bag cover, so the cover may be separated immediately during handling of the file. When adjusting the width of the back cover by sliding, if the binding width of the paper becomes large to some extent, the back cover will come off from the bag cover when adjusting the width of the back cover by sliding the back cover. was there.

In view of the above, the present invention comprises a bag cover having one opening and a cover having a back cover arranged in a row. In the file in which the width of the back cover inserted in the bag cover can be adjusted, the back cover is the bag cover. It provides files that cannot be easily removed from.

[0005]

[Means for Solving the Problems]

 The present invention is composed of a bag cover with one side open and a cover with a back cover connected to each other.Both bindings are provided with a binding section, the back cover is inserted into the bag cover, and the back cover is slid to slide the back cover. In the file that can adjust the width of the cover, a folding piece is provided on the inside of the bag on the bag cover, and at the end of the spine cover connected to the cover, the folding piece is folded inside the bag of the bag cover. It is a file with a stopper that can adjust the width of the spine cover provided with a bent piece that engages with.

[0006]

[Embodiment of the invention]

 FIG. 1 is a perspective view showing an embodiment of a file of the present invention, FIG. 2 is a sectional view showing folded pieces of a bag cover and a spine cover of the file of the present invention, and FIG. 3 is a state in which the file of the present invention is assembled. In the perspective view shown, either one of the front cover and the back cover is a bag cover 1 with one opening, and the other cover 2 has a spine cover 3 connected at its end, and the cover 2 and the spine cover 3 are It is integrated.

As the material for the cover, as in the case of the conventional cover, for example, paper or plastic such as polypropylene or vinyl chloride can be used.

The cover may be a well-known cover having a window, a pocket, or the like. Furthermore, a hook or a hook or a tape may be attached to the ends of the front cover and the back cover, or to a band or a band. A front cover and a back cover may be stopped by providing a flap or the like.

A binding portion 4 for sheets is provided on the cover sheet. As the binding portion 4, for example, as shown in the figure, a rising piece 4a is provided at an end portion of the bag cover 1 and a binding hole is provided by eyelets or the like. 4b is formed, and the other cover 2 is provided with a rising piece 4a in which a binding hole 4b is formed in a portion corresponding to the end of the cover 2 near the boundary between the cover 2 and the spine 3. The rising piece 4a may be formed by folding a piece of thick paper, or the rising piece 4a may be separately prepared and fixed to the cover sheet 2. For the paper, a binding string may be bound through the binding holes 4b of the rising piece 4a and the binding hole of the paper, or a book screw may be used instead of the binding string, or a band may be fixed to the rising piece of one cover sheet. However, it can be bound by a well-known binding means such as a binding tool that fixes the band with a fastener fitting on the rising piece of the other cover.

It is convenient to provide the spine cover 3 with a plurality of folding grooves 3a so that the back cover 3 can be easily folded according to the thickness of the sheets when binding the sheets.

Inside the bag 1a at the end of the bag cover 1, a bent piece 5 that is bent inside the bag 1a is provided on the opposite side of the rising piece 4a. The bent piece 5 may be formed by bending the end of the bag cover 1 and may be prepared separately and fixed with an adhesive or the like.

At the end of the spine cover 3 connected to the other cover 2, a bent piece 6 is provided on the opposite side of the rising piece 4a, and the bent piece 6 is a folded piece of the bag cover 1. It is formed so as to face the bending piece 5 and be bent in the opposite direction, and to engage with the bending piece 6 of the bag cover 1.

A method of using the file of the present invention will be described.

When the folded piece 6 of the spine cover 3 connected to the other cover 2 from the opening of the bag 1a of the bag cover 1 is inserted and pushed in the direction of the arrow shown in FIG. 1, the folded piece 6 of the spine cover 3 is inserted. Goes over the folded piece 5 of the bag cover 1 and is stored in the bag 1a.

Next, the sheets to be bound are set between the rising pieces 4a formed on the front and rear covers 1 and 2, the spine cover 3 is slid and adjusted according to the thickness of the sheets to be bound, and then the sheets are bound. Stuff in. When the spine cover 3 is slid and adjusted, even if the spine cover is pulled too much, the bent piece 5 of the spine cover 3 engages with the bent piece 6 of the bag cover 1 as shown by the phantom line in FIG. Since it functions as a stopper, the spine cover 3 does not come off from the bag cover 1.

[0016]

[Effect of the invention]

 Since the folded pieces of the spine cover and the folded pieces of the bag cover engage with each other and function as a stopper, it is possible to prevent the spine cover from coming off the bag cover.
