【Example】

 Hereinafter, the illustrated embodiment of the present invention will be described. First, as shown in FIG. 1, the file binding device of the present invention includes a pin mounting base 1 and a plurality of pin bodies 2 mounted on the pin mounting base 1. As shown in FIG. 3, the pin mount 1 is fixed with rivets 6 to both ends of the inner surface of the spine portion 17 of the cover 16 in the form of a cover.

The pin mounting base 1 is composed of a cover plate 3, a substrate 4 and a side plate 5. The cover plate 3 is bent so that the portion excluding the inner end protrudes upward, and the inner end is fixed to the spine 17 of the cover 16 by the rivet 6. The cover plate 3 is provided with a locking rib 9 projecting downward on the lower surface of the portion projecting upward. The locking rib 9 is perpendicular to the inside and outside directions. In addition, the substrate 4 is provided with locking ribs 7 and 8 projecting upward at two places on both the inner and outer ends of the upper surface. The locking ribs 7, 8 are also oriented vertically with respect to the inside and outside directions. The substrate 4 is located below the portion of the cover plate 3 that protrudes upward, and is located on the same plane as the inner end of the cover plate 3, so that the substrate 4 is located between the portion of the cover plate 3 that protrudes upward. Is formed at one end thereof. The inner locking ribs 7 provided on the substrate 4 are hidden under a portion protruding above the cover plate 3, and the outer locking ribs 8 are exposed outside the cover plate 3. The locking rib 9 provided on the lower surface of the cover plate 3 and the locking rib 7 inside the substrate 4 provided so as to be hidden under the cover plate 3 are arranged so as to be displaced inward and outward. .

[0007] The pin body 2 has substantially parallel claw pieces 11 and mounting pieces 12 that are integrally arranged at the outer end and separated from each other at the inner end, and are located below the claw pieces 11 and the mounting pieces 12. Notch recesses 13 and 14 are provided at two locations at the inner and outer ends of the lower edge of the mounting piece 12, and a notch recess 15 is also provided at the upper edge of the mounting piece 12 facing the claw piece 11.

The pin body 2 is mounted on the pin mounting base 1 such that the mounting pieces 12 are inserted into the holes 10 and the claw pieces 11 are exposed above the cover plate 3. The two inner and outer locking ribs 7 and 8 provided on the substrate 4 are fitted into two inner and outer cutout recesses 13 and 14 provided on the lower edge of the mounting piece 12, respectively. The locking rib 9 provided on the lower surface of the cover plate 3 is fitted into the notch 15 provided in the portion.

As shown in FIG. 3, a booklet 18 such as a magazine or a pamphlet has two ends between the claw 11 of the pin body 2 and a portion of the cover plate 3 of the pin mounting base 1 projecting upward. It is filed in between.

[0010]

[Effect of the invention]

 The configuration of the file binding device of the present invention is as described above, and the pin mounting table 1 is provided in the notch recesses 13, 14, and 15 provided at the lower edge and the upper edge of the mounting piece 12 of the pin body 2, respectively. The pin body 2 is mounted on the pin mount 1 with the locking ribs 7, 8, 9 provided on the substrate 4 and the cover plate 3 fitted therein, so that the pin body 2 is bent, tilted, or twisted. Therefore, it is difficult to remove the locking ribs 7, 8, 9 from the cutout recesses 13, 14, 15 and the effect that the pin body 2 can be securely prevented from dropping from the pin mounting base 1 is obtained. is there. In addition, since the locking ribs 7, 8, 9 provided on the pin mounting base 1 also have a function of guiding the pin body 2, there is also an effect that the pin body 2 can move smoothly in a direction perpendicular to the inside and outside directions. .
