Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a file that binds a document or the like by passing an elongated strip through a hole formed in the document or the like.

[0002]

[Prior art]

 A typical typical file of this type is a flat file. However, the flat file has a complaint that the binding device including the strip is required to be manufactured separately from the cover body and attached to the cover body, which increases the cost. There is also a complaint that it is difficult to make copies because it is difficult to open both sides of a document or the like in the bound state. In addition, there is also a complaint that the strips passed through holes in documents and the like cannot be hooked smoothly and are difficult to use.

[0003]

[Problems to be solved by the invention]

 Therefore, the present invention provides a file that can be manufactured at low cost, and that can be easily copied by opening both sides of a document or the like while the document is being stapled, and furthermore, the strip can be smoothly hooked and used. As an issue.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the file of the present invention is cut into a part of the front cover part 2 of the cover body 1 made of a plastic sheet in which the front cover part 2, the spine cover part 3 and the back cover part 4 are formed in series. 7, the elongated flexible strip 5 having claw portions 8 protruding outward in the width direction is formed at a plurality of positions such as the front end and the intermediate portion, and the back of the cover 1 is formed. A notch 11 is also provided at a position facing the band-shaped piece 5 provided on the front cover part 2 on the front cover part 4 to form a undulating self-supporting piece 9. A tapered opening 13 having a wide end through which the claw portion 8 is provided and into which the claw 8 can be inserted and coming out, and gradually narrowing inward from the end; Narrowest A through hole 12 is formed by connecting a hooking opening 14 that allows insertion and removal of a portion of the strip 5 having the same width as that of the claw portion 8 at the same width as that of the position, and allows passage of only the other portion. The configuration is characterized by being provided.

[0005]

【Example】

 Hereinafter, the illustrated embodiment of the present invention will be described. First, FIGS. 1 and 2 show the unfolded state of the cover 1. The cover 1 is made of a plastic sheet such as PP and has a front cover 2, a spine 3 and a back cover 4 in series. The front cover 2 is provided with a pair of upper and lower strips 5. The strip 5 is parallel and elongated with respect to the top and the ground, and the inner end located near the bending line 6 provided at the boundary with the spine 3 is continuous with the front cover 2. The part is cut off from the front cover part 2 by a cut 7. That is, the strip 5 is formed by providing the notch 7 in the front cover 2. The strip 5 is provided with claw portions 8 protruding outward in the width direction at the front end (outer end) and the intermediate portion. Since the strip 5 is made of a plastic sheet and has flexibility as described above, it can be raised and bent inward. In this embodiment, the claw portions 8 are provided at two positions, that is, at the front end and the intermediate portion of the strip 5, but the number of the claw portions 8 can be increased.

A hooking piece 9 is provided on the back cover part 4 of the cover body 1 at a position facing the strip 5 provided on the front cover part 2. This hooking piece 9 is also formed by providing a cut 11 in the back cover part 4, and the inner end is continuous with a bending line 10 provided at the boundary with the back cover part 3, but the other parts are It is separated from the back cover part 4 by the cut 11. The hook pieces 9 can be raised and lowered with respect to the back cover part 4. The hooking piece 9 has a wide end at which the claw 8 of the strip 5 can be inserted and escaped, and has a tapered shape that gradually narrows inward from the end. It is not possible to insert and remove the opening 13 and the place where the claw 8 of the strip 5 is provided with the same width as the narrowest part of the tapered opening 13 and only the other parts can pass. A through hole 12 having a structure that is continuous with the latching opening 14 is formed.

Next, FIG. 3 shows a state in which documents 15 are bound. First, the strip 5 is inserted into a hole 16 formed in a document 15 or the like. Next, after inserting the strip 5 into the widest end of the tapered opening 13 in the through hole 12 of the hooking piece 9, the tapered opening 13 is inserted into the narrower inner portion. Then, after passing through the tapered opening 14, it is advanced into the hooking opening 14, and the claw 8 of the strip 5 is hooked on the edge of the hooking opening 14. This completes the binding of the document 15 or the like. As described above, the tapered opening 13 is provided in the through hole 12 of the hooking piece 9, so that when the belt-like piece 5 enters the hooking opening 14 and is hooked, there is a step on the way. Without being stopped by being caught, it can be guided by the tapered opening 13 to smoothly enter the hooking opening 14 and be hooked. In the case where the strip 5 is inserted into the through hole 12 of the hooking piece 9 to be hooked, the work is facilitated by raising the hooking piece 9 with respect to the back cover part 4. Further, since the hooking piece 9 can be laid down until it is substantially flush with the back cover 4, and the strip 5 is flexible and easily deformed, it is shown in FIG. As described above, it is possible to open both sides of the document 15 in the bound state, which facilitates copying.

[0008]

[Effect of the invention]

 The file of the present invention is as described above, and the band-shaped piece 5 and the hooking piece 9 for binding the documents 15 can be integrally formed by providing the cutouts 7 and 11 in the cover body 1. The cost can be significantly reduced compared to conventional products, which require that tools be manufactured separately and attached to the cover. Further, since the document 15 can be opened on both sides in the bound state, there is an advantage that copying can be easily performed. Further, since the strips 5 are provided with the claw portions 8 at a plurality of positions such as the front end and the intermediate portion, there is an advantage that the tightening of the strips 5 with respect to the document 15 can be adjusted so as to be strong or loose. In addition, since the tapered opening 13 is provided in the through hole 12 of the hooking piece 9, when the belt-like piece 5 enters the hooking opening 14 and is hooked, the belt-like piece 5 may have a step on the way. The strip 5 is guided by the tapered opening 13 and smoothly enters the hooking opening 14 to be hooked. Therefore, when the belt-shaped piece 5 is hung on the hooking opening 14, no trouble is taken, and the hooking work is easy and convenient.
