Abstract

(57) [Abstract] [Purpose] The present invention is intended to enable binding of a bundle of paper bound by binding pins to a binding rod attachment file for each theme. [Structure] A rod-shaped binding pin is inserted into the perforation of paper, a fitting ring is fitted and fixed to the tip protruding portion, and a fastening ring is extended from at least one end of the rod-shaped binding pin to form a binding rod attachment file. A paper bundle binding device designed to be fixed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is to bind a bundle of about 50 to 200 sheets punched by a punching machine generally called a punch to a binding rod attachment file for binding with a rod-shaped binding pin and a fitting ring. It relates to the device.

[0002]

[Prior art]

 The sheet bundle punched by the punching machine is generally bound into a file as shown in FIG. 3 of Japanese Utility Model Laid-Open No. 52-64026. However, in recent years, it has come to be bound by a binding tool as shown in FIG. 4 of JP-A-62-218197. This has the advantage that the length of the binding tool can be adjusted according to the thickness of the bundle of paper to be bound and the number of installation locations can be reduced. The binding tool will be briefly described below. By binding a ring-shaped female member to a male member having sawtooth-shaped male teeth formed on the outer circumference, a paper bundle (document) can be bound. Has become.

[0003]

[Problems to be solved by the device]

 However, the binding device of the above-mentioned conventional technique has an advantage that it can be installed in a small number of places, but for example, as shown in Japanese Utility Model Publication No. 52-64026, the paper bundle bound by the binding device is shown by theme. In order to continuously bind to such a file, it was necessary to once cut the rod-shaped binding tool, separate the bundle of paper, and re-file it. Then, it was necessary to divide it by theme such as adding partitions. In addition, when using one of the divided parts according to the theme during use, there is a problem that the extracted separated bundle of paper is scattered.

[0004]

Means for Solving the Problems The present invention is intended to solve the above-mentioned problems, and a rod-shaped binding pin is inserted into the perforation of the paper, and a fitting ring is fitted and fixed to the protruding end portion of the paper. It is characterized in that a fastening ring is extended from at least one end of the binding pin so as to be fastened to the file with the binding rod.

[0005]

【Example】

 A collar portion 2 is formed at one end of the hollow binding pin 1, and a hollow hollow portion 3 is formed inside. Further, locking projections 4 are formed on the outer periphery at appropriate intervals. Further, a fastening ring 6 is provided on the collar portion 2 via an arm portion 5 (see FIG. 1). The diameter of the inner hole 7 of the fastening ring 6 is slightly larger than that of the binding rod of the file with the binding rod as shown in the prior art. On the other hand, the diameter of the inner hole 9 of the fitting ring 8 fitted to the binding pin 1 is formed to be slightly larger than the diameter of the valley portion 1a of the binding pin 1. The binding pin 1 and the fitting ring 8 may have the same hardness (polyethylene, etc.), but even if the binding pin 1 and the fitting ring 8 are made of the same material, the fitting ring 8 is a little better than the binding pin 1. It is better to use a solid material.

Further, as shown in FIG. 2, the fastening ring 6 may be extended to the fitting ring 8. By forming the fastening ring 6 on both the binding pin 1 and the fitting ring 8, stable filing can be achieved. Although the fastening ring 6 is integrally formed with the binding pin 1 or the fitting ring 8 in this embodiment, the binding pin 1 may be a separate member. That is, the fitting ring 8 having the fastening ring 6 as shown in FIG. 2 may be fitted to the collar portion 2 of the binding pin 1.

Next, the usage method will be described. After finishing punching the sheet bundle, the binding pin 1 having the retaining ring 6 formed therein is inserted into the punched hole. Next, the fitting ring 8 is fitted and the tip of the extra binding pin 1 is cut. Next, the fastening ring 6 is inserted into the binding rod P of the binding rod file W (see FIG. 3). Although the fastening ring 6 may be formed only on the fitting ring 8, the fastening ring 6 is formed on the binding pin 1 at least in consideration of the possibility of the fitting ring 8 coming off the binding pin 1. It is better to do it. Further, although the binding rod is rod-shaped in this example, it may be a band made of a relatively soft plastic material.

[Effect of device]

 According to the present invention, a rod-shaped binding pin is inserted into a perforation of paper, a fitting ring is fitted and fixed to a tip protruding portion, a fastening ring is extended from at least one end of the rod-shaped binding pin, and a binding bar with a binding rod is attached. Since it is fixed to the file, it is possible to file in a divided state without removing the binding tool, and even when using it, it is possible to extract and use only the portion bound by the binding tool without separating it .
