Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a file, and more particularly to a file for holding paper sheets such as large-sized drawings or office papers.

Conventionally, as shown in Japanese Utility Model Publication No. 50-4022, as a device for holding paper sheets such as drawings or office papers, a file body consisting of a front part, a back part, and a back part is attached to one side of the file body. A polymer connected to the back is attached, and its three side edge parts are attached to the side edges of the main body to form a bag, and a part of the polymer opposite to the back is wider than the back and , a structure in which two folds are formed along the back part to form a pressing piece is known.

By the way, for a file with such a structure,
When the cover main body is folded in two around the back, the pressing piece facing the back of the polymer is bent from the fold, and the bending reaction force generated at this time is applied to each fold. The stored paper sheets can be held in the bag by pressing the adjacent parts against the front and back sides, but since the bending direction of the pressing piece is not restricted to one direction, the cover body When folding, if the intermediate portion between the folds is not deformed in a direction away from the back, this intermediate portion will act as a tension, making it impossible to bend the pressing piece along the fold. Therefore, there was a problem that the cover main body could not be folded smoothly.

Furthermore, this problem was especially noticeable when the file size was increased to accommodate large drawings, such as A2 size drawings.

Therefore, the present invention was devised in view of the above problems, and the purpose is to always restrict the bending direction of the pressing piece to one side even if the file size is large, so that the cover body can be folded. It is an object of the present invention to provide a file which can be firmly and firmly tightened by increasing the pressing force of the pressing member against the paper piece.

Therefore, the present invention forms a paper holding part by attaching overlapping pieces connected to each part to one surface of the file main body, which consists of a front part, a back part, and a back part, and also attaches the overlapping pieces to the back part of the overlapping pieces. A pair of folds that are wider than the spine and run along the length of the spine are provided at opposing locations to form a pressing piece for the sheet, while the back side of the pressing piece is This is characterized by the provision of a regulating piece that regulates the bending direction of the pressing piece in one direction.

Embodiments of the file according to the present invention will be described in detail below based on the drawings.

Reference numeral 1 denotes a cover body made of rectangular cardboard with fold lines 1a and 1b to form a front part 11, a back part 12, and a back part 13. Overlapping pieces 2, 2 of a required width that are connected to the back part 12 and back part 13 are integrally drawn out, a crease line is provided in the continuous part of these overlapping pieces 2, 2, and both overlapping pieces 2, 2 are attached to the cover main body 1. It is folded back along one side to form holding parts A, A for holding large sheets of paper, such as A2 size drawings, for example, and
Folded pieces 4, 4 are integrally extended from both side edges of the cover main body 1, and these folded pieces 4, 4 are folded back from the continuous portion and overlapped with the upper part of one side of each of the overlapping pieces 2, 2.

Then, in the portions of both of the overlapping pieces 2, 2 facing the back portion 12, there are two folds 2 that are wider than the back portion 12 and run along the back portion 12.
a, 2b to form pressing pieces 20, 20, respectively, and creases 2c, 2c are formed in the intermediate parts of these pressing pieces 20, 20, and both pressing pieces 20,
Approximately V-shaped regulating pieces 3, 3 for regulating the bending direction of the pressing pieces 20, 20 in one direction are provided on the back surface of the pressing member 20. Also, the back part 1 of both pressing pieces 20, 20
Notches 21, 21 are provided on the upper and lower edge portions of 2, and elongated holes 22, 21 are provided between the folds 2a, 2b.
22... are formed to facilitate bending of the respective pressing pieces 20, 20 and overlapping pieces 2, 2.

5, 5... are hook-and-loop fasteners provided on the outer surfaces of both end portions of both overlapping pieces 2, 2, and at locations corresponding to the hook-and-loop fasteners 5, 5... of the folded pieces 4, 4,
Through-holes 41, 41... through which the surface fasteners 5, 5... can be inserted are respectively formed, and when the cover main body 1 is folded in half, the surface fasteners 5, 5... on the front part 11 and the back part 13 are mutually inserted. by engaging with the front part 11
and the back portion 13 can be maintained in a polymerized state.

In the above embodiments, the overlapping piece 2 and the folded piece 4 are integrally formed on the cover body 1, but the overlapping piece 2 and the folded piece 4 may be formed separately from the cover body 1. In this case, an attachment piece is provided in series from the connecting end of the overlapping piece 2 and the folded piece 4 with the cover body 1, and the overlapping piece 2 and the folded piece 4 are attached to the cover body 1 by bending this attachment piece and applying glue. It is installed on.

The file of this invention is structured as described above.
When using this file, open the cover main body 1, folding pieces 4, 4, and upper overlapping piece 2 as shown in FIG. Side overlapping piece 2 and folded pieces 4, 4
The sheet is folded back toward the cover body 1 side as shown by the solid line in FIG. Fold it in half so that the numbers 13 and 13 overlap, and store it on the bookshelf as usual.

When the cover body 1 is folded in half as described above, the pressing piece 20 facing the spine 12 is folded into the fifth
As shown in the figure, the pressing portion 20 is bent into a mountain shape along the respective folds 2a, 2b, and 2c.
A regulating piece 3 is provided on the back side of the cover body 1, and when the cover main body 1 is opened, the regulating piece 3 aligns the fold 2c of the pressing piece 20 with the arrow as shown in FIG. Since it is regulated to be bendable only in the direction,
The fold 2c portion can be bent in the direction of the arrow to form a mountain shape without being bent in the opposite direction to the direction of the arrow. Further, since the interval between the folds 2a and 2b of the pressing piece 20 is wider than the interval between the back part 12, a reaction force is generated when the pressing piece 20 is bent, and the regulating piece 3 is bent to a certain extent to approach the bending limit. For example, contrary to the action of restricting the bending direction of the pressing piece 20, an action of stretching the pressing piece 20 in the bending direction acts, and these actions cause the bending of the pressing piece 20 to Since the holding parts are pressed against the front part 11 and the back part 13, the paper sheets stored in the holding parts A, A are reliably held by this pressing force.

As shown in the drawing, by forming the interval between the folds 2a and 2b into a tapered shape, the reaction force at the time of folding increases as the interval increases, so that the sheet of paper can be held under pressure. can be carried out more reliably.

Further, the fold 2c is not particularly necessary, and for example, when the fold 2c is not provided, the pressing part 2 of the polymeric piece 2
0 is curved in an arc shape in the direction of the arrow in FIG. 4 by the regulating piece 3, a reaction force is applied in the same manner as described above. Further, 6 is a storage section for index cards.

As described above, the present invention forms a paper holding part by attaching overlapping pieces connected to each part to one surface of a file main body consisting of a front part, a back part, and a back part, and the back part of the overlapping piece A pair of folds, which are wider than the spine and run along the length of the spine, are provided at opposing locations to form a pressing piece of the paper sheet, while on the back side of the pressing piece, Since a regulating piece is provided that regulates the bending direction of the pressing piece in one direction, when the cover main body is folded, the regulating piece provided on the back side of the pressing piece of the overlapping piece, The bending direction of the pressing piece can be oriented in one direction in which the cover main body can be folded, so that the pressing piece does not bend from the fold line as in the conventional example, and the pressing piece is folded in the middle of the pressing piece. There is no possibility that the cover body will be unable to be folded due to the part sticking out on the back side. The cover body can be folded by easily folding the pieces from the folds, and furthermore, when the cover body is folded, the interval between the folds of the pressing piece is wider than the interval between the spines. In addition to the reaction force of the pressing piece itself, by applying the reaction force of the restricting piece as the restricting piece approaches its bending limit, the folded portion of the pressing piece is bent to the front and back sides. It can be pressed forcefully, and the paper sheets stored in the holding section can be reliably held within the holding section by this pressing force.
