Description

[Detailed description of the invention] This invention relates to a fastener for filing an appropriate number of sheets of paper or printed matter of various sizes such as A4 size or B5 size.

Conventionally, in this type of method, a flat string-like piece made of a thin metal plate or thin synthetic resin was passed through a punch hole in the piece of paper to be filed, and both ends of the string-like piece were bent to hold the paper piece down. There are some that maintain this bent state by various means.

However, since the folded piece in each of these is thin, its side edge forms a knife-like shape, and there is a risk that the folded piece may tear the periphery of the punched hole of the inserted piece of paper, causing the piece of paper to fall off from the file.

The purpose of the present invention is to improve the fastener for paper strips which has such problems.

Also, the edge of the punched hole in the paper strip should not come into direct contact with the sharp side edge of the base of the folded piece.

Another object is to allow the folded piece to be smoothly inserted into the punched hole of the paper piece up to its base.

To explain this invention based on the attached drawings, bent pieces 2 each having a width b narrower than the width B of the substrate 1 are attached to both ends of an elongated substrate 1 along its extension line.
3 is integrally formed, the whole is made into a straight line, and both side edges of the bases 2c, 3c of both bent pieces 2, 3 are cut out to have a width c slightly narrower than the width b mentioned above, and this is made with a soft pipe 6. Either it is covered as shown in Figs. 1 and 3, or a soft pipe 6 such as a vinyl pipe is fitted therein as shown in Fig. 8.

Furthermore, protruding pieces 5a are provided on both sides of one bent piece 2.
5b, and bend them so as to face each other to form an inserted part 4 into which the other folded piece 3 is inserted, and punch the paper piece 7 in which both folded pieces 2 and 3 are to be filed. Insert the bent pieces 2 and 3 into the hole 8, bend each bent piece 2 and 3 along the dashed-dotted lines 2a and 3a as shown in FIG. It is also bent to the position indicated by two-dot chain lines 2b and 3b, and held in that state by the inserted portion 4.

Next, when unraveling this file, while pulling out the other folded piece 3 inserted into the inserted part 4, both folded pieces 2 and 3 are raised up, and in this state, the paper piece 7 is folded between the folded pieces 2 and 3. It is used to extract pieces of paper from the paper or to newly file pieces of paper (not shown).

Since the present invention has the above-described configuration, when each piece of paper 7 is filed, the periphery of the punch hole 8 of the piece of paper 7 does not directly touch the thin knife-like portions on both sides of the folded pieces 2 and 3. Since contact is made through the soft pipe 6, there is no risk of damage to the periphery of the punch hole 8 and the paper piece 7 falling off, unlike in the conventional case.

Further, since the soft pipe 6 is fitted to the base of each of the bent pieces 2 and 3, when the bent pieces are bent from the base, the soft pipe 6 is also bent together, and there is no problem in the operation.

Furthermore, since the width c of the bases 2c and 3c of each bent piece 2 and 3 is smaller than the width b of both bent pieces 2 and 3, there is a space between both side edges of the bent pieces 2 and 3 and the outer surface of the soft pipe 6. Since there is no step, this part can be smoothly passed through the punch hole 8 of the paper piece 7.
