[Embodiment of the invention]

 FIG. 1 is a perspective view showing an example of a binding device according to the present invention, FIG. 2 (A) is a front view thereof, FIG. 2 (B) is a side view thereof, and FIG. It is a top view. 3A is a cross-sectional view of the binding device shown in FIG. 1, and FIG. 3B is a cross-sectional view showing a state in which the binding device shown in FIG. It is a figure. The binding device 10 shown in FIG. 1 is for two holes, and is formed shorter than the length of the spine cover H and the edge side Pe of the paper P to be bound. The binding device 10 shown in FIG. 1 includes a substantially rectangular case 12 made of a synthetic resin such as polypropylene. The case 12 is arranged in parallel with the extending direction of the spine H and the edge side Pe of the sheets P to be bound. In this specification, this direction is called the length direction, and the direction orthogonal to this length direction is called the width direction. A rectangular opening 14 is formed on the front surface of the case 12, and the back surface is brought into contact with the inner surface of the spine cover H of the file or binder. Mounting holes 18 are formed in the inner bottom portion of the case 12 in the vicinity of both ends in the lengthwise direction thereof so as to penetrate in the thickness direction. As shown in FIG. 3, the mounting hole 18 is for fixing the case 12 and the spine cover F by caulking them integrally by inserting a fixing tool F such as an eyelet. Here, the eyelet was used as the fastener here, but the fastener is not limited to this and may be, for example, a screw, a bolt nut, a rivet or the like. Further, the case 12 may be fixed to the spine cover F 1 by, for example, high frequency welding. In this specification, the paper is not limited to paper, but includes all those bound by a binder or a file, such as a film, a sheet, and a case.

As shown in FIGS. 2A and 3, in the vicinity of the four corners of the opening 14 of the case 12, locking projections 20 having a substantially triangular cross section are formed so as to project inward from the open edges. To be done. The locking projections 20 press the four corners of the cover portion 28a of the holding member 28, which will be described later, from the upper side to the lower side in FIG. A pedestal portion 22 is formed on the inner bottom surface of the case 12 at least at a position facing the locking projection 20 in the thickness direction. In the binding device 10 of this embodiment, the pedestal portions 22 are formed in elongated shapes extending in the length direction on both sides in the width direction inside the case 12. The pedestal portion 22 is for placing a holding member 28, which will be described later, and for sandwiching the holding member 28 between the pedestal portion 22 and the locking projection 20.

A substantially rectangular holding member 28 is detachably attached to the opening 14 of the case 12, as shown in FIGS. 1 and 3A. The holding member 28 is made of a metal having elasticity, and its cross-sectional shape is, as shown in FIG. 3, a cover portion 28a having an arcuate curved surface, and both sides in the width direction thereof are bent to project downward in FIG. And a folded-back portion 28b formed therein, and has a substantially U-shaped cross section as a whole. The holding member 28 is for holding a movable piece, which will be described later, while always urging the movable piece from both sides in the width direction to the inside. This holding member 28 has sharp portions at both ends in the length direction and at the four corners, and these portions are shown in FIG. 2 (A), FIG. 2 (B) and FIG. 3 (A). As shown, it is entirely covered by a case 12 made of synthetic resin. As shown in FIG. 3, the holding member 28 is placed on the pedestal portions 22 on both sides in the width direction inside the case 12 with the lower end edges of the folded portions 28b abutting against each other. Then, as shown in FIG. 2 (A), the vicinity of the four corners of the upper surface of the cover portion 28a is pressed by the locking projections 20, and the folded portion 28b forms a more acute angle with the inner surface of the cover portion 28a. It is compressed to become. Then, due to the elastic force, a force that tries to return to the original state acts between the cover portion 28a and the folded portion 28b, so that the holding member 28 is urged by the elastic force, and between the locking projection 20 and the pedestal portion 22. It is firmly clamped in. At the time of manufacturing, the holding member 28 is attached to the case 12 by pushing the holding member 28 into the case 12 from the upper side to the lower side in FIG. On the other hand, when discarding the binding device 10, the holding member 28 can be removed from the case 12 by pulling the holding member 28 strongly with a force greater than the force applied during normal use. This is because in the binding device 10 of this example, the locking projections 20 are formed only in the vicinity of the four corners in the above-described shape, and the holding member 28 is made of elastic metal. However, the size of the locking projection 20 and the elasticity of the holding member 28 are, of course, appropriately adjusted at the time of designing so that they will not come off during use and have sufficient strength for practical use. .

As shown in FIG. 3, a movable piece 30 having a substantially V-shaped cross section is housed inside the holding member 28. The movable piece 30 is formed such that, for example, two metal plates 31 having substantially the same length as the holding member 28 are arranged in parallel in the width direction, but are abutted at the central portion shown in FIG. 3 and bent at the central portion. The same as that conventionally used for ring binders. The movable piece 30 is for fixing a binding rod 32, which will be described later, to be integrally opened and closed, and is bent to have a substantially V-shaped cross section or a substantially inverted V-shaped cross section. It is stably maintained in the state of.

Near the both ends in the length direction of the movable piece 30, substantially annular metal binding rods 30 are fixed. The binding rod 32 is used for binding the paper P by inserting it into a binding hole formed in the paper P in advance, and is the same as that conventionally used. The binding rod 32 includes a pair of substantially semicircular claws 32a and 32b. The pair of claws 32a and 32b are formed such that one ends thereof are fixed to the movable piece 30 and the other ends thereof penetrate the holding member 28 in the thickness direction and extend outward, so that the two are engaged with each other in the central portion. Has been done. When the movable piece 30 is in a substantially inverted V shape, the other ends of the pair of claws 32a, 32b are separated from each other and the binding rod 32 is opened, and when the movable piece 30 is in a substantially V shape. The other ends of the pair of claws 32a and 32b are engaged with each other to close the binding rod 32. In the binding device 10, the user opens and closes the binding rod 32 by gripping the pair of claws 32a and 32b.

In this binding device 10, since the case 12 made of synthetic resin, the holding member 28 made of metal, the movable piece 30 and the binding rod 32 can be easily separated, the synthetic resin parts are also made of synthetic resin or the like. It can be discarded together with the cover sheet formed in step 1, and metal parts can be discarded separately from them. Therefore, it is easy to adapt to the separate disposal and recycling that are socially demanded today. In use of the binding device 10, the above-described metal members are housed in a synthetic resin case 12 when used, and the sharp corners and end faces of the holding member 28 are covered by the case 12. Therefore, there is no possibility that the user may hurt the finger.

Although the binding device 10 described above has two binding rods 32, the binding device 32 is not limited to this, and two or more binding rods 32 may be provided in the same configuration as described above.
