Abstract

(57) [Summary] [Object] To provide a file binding device that is firmly fixed at the time of binding, but can be discarded as a combustible material when discarded. A plastic file binding device (8) penetrating between holes (14) of a left and right base (10) attached to a spine (6) of a binder. It comprises a head (8a), an elongated body (8b), and a leg (8d) having a spring. The leg (8d) is provided with a bulge (8e) having a larger diameter than the hole (14). The spring is, for example, a groove (8c). The width (t1) of the bulge (8d) in the natural state is not only larger than the diameter of the hole (14) in the left and right bases, but also the width (t2) of the state without the groove (8c) is larger than that of the hole (14). Preferably slightly larger.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a file binding device. In particular, it relates to a frequently updated product sample book, etc., which is not replaced on a page-by-page basis but is replaced as a whole as a file binding device.

[0002]

[Prior art]

 There are several types of non-additional files. The object of the present invention is mainly a type that is bound by a stick that penetrates a hole between the left and right bases attached to the spine of the binder.

[0003] In this type of file, for example, a "U" -shaped metal rod is used, which penetrates between left and right base holes attached to a binder spine. The dropout is prevented by the vertical and horizontal portions of the "U".

[0004]

[Problems to be solved by the invention]

 When such files were incinerated, only the metal rods were left unburned, and the processing was time-consuming and time-consuming.

[0005] An object of the present invention is to provide a file binding device that is firmly fixed at the time of binding, but can be discarded as a combustible material when discarded.

[0006]

[Means for Solving the Problems]

 The present invention is a plastic file binding device penetrating between left and right base holes attached to a spine of a binder, comprising a head, an elongated body, and a leg having a spring. Is provided with a bulge having a larger diameter than the hole.

[0007]

[Embodiment of the invention]

 The spring is, for example, a groove for dividing the leg into two or four parts.

It is preferable that the width of the bulge in the natural state is not only larger than the diameter of the hole at the left and right bases, but also that the state without the groove is slightly larger than the hole.

The file binding device of the present invention is preferably manufactured by engineering plastic to increase the strength. In particular, polyacetal (POM) is preferable.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view of a binder using the file binding device of the present invention. FIG. 2 shows the file binding device of the present invention. FIG. 3 is a plan view (b) and a sectional view (a) of a binder using the file binding device of the present invention.

As shown in FIGS. 1 and 3, the binder has a front cover 2, a back cover 4, and a spine 6 positioned therebetween. Left and right bases 10 for attaching the file binding device 8 are attached to the spine portion 6. The left and right bases are L-shaped (or inverted L-shaped) members in cross section, and the L-shaped bottom surface 10 a is firmly attached to the spine with pins 12. Holes 14 for attaching the file binding device 8 are provided at predetermined intervals on the L-shaped side surface 10b.

The file binding device 8 of the present invention is inserted through the plurality of holes 14 formed in the left and right bases 10.

As shown in FIG. 2, the file binding device 8 includes a head portion 8a, an elongated main body 8b, and legs 8d that are bifurcated by grooves 8c. The leg is provided with a bulge 8e, which is also divided by the groove 8c. The width t ₁ of the bulge 8 e in the natural state is not only larger than the diameter of the hole 14 in the left and right bases, but also the width t _{2 in} the state where the groove 8 c is compressed from above and below is slightly larger than the hole 14. The file binding device 8 is formed of engineering plastic (for example, polyacetal).

To bind a file document, the document is placed between the left and right bases, and the file binding tool 8 penetrates the hole 14 and the binding hole previously formed in the document. A machine for driving the file binding tool may be used, but human power is sufficient. The bulge 8e of the file binding tool overcomes the resistance of the holes 14 in the left and right bases, advances while contracting the groove 8c, and stops in the state of FIG. When the groove 8c is restored to the natural state in this state, the file binding tool 8 can no longer easily come out of the left and right bases.

[0016]

[Effect of the invention]

 Since the file binding device of the present invention does not come off easily, it is suitable for binding non-removable documents. In addition, since no metal is used, the whole can be burned as a combustible as it is.
