Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a binding tool for paper or the like, which has a ring that is inserted into a hole formed in the paper or the like.

[0002]

[Prior art]

 Conventionally, a plurality of substantially U-shaped rings are arranged in parallel, a common mounting shaft is provided at one end of each ring, and a hook is provided at the other end of the ring to provide a free end. The above mounting shaft is rotatably assembled at one end in the width direction, and a mounting / demounting hole is provided at the other end in the width direction of the board into which the free end of the ring is inserted and can be removed. When the flexible operation plate is attached to the board and the operation plate is slid inward, it is locked to the free end hook of the ring inserted into the attachment / detachment hole of the board and the operation plate is slid outward. There is also a binding tool having a structure in which a claw piece that disengages from the hook and releases the locked state of the free end of the ring is provided on the operation plate.

In the above-described conventional binding device, when the free end of the ring is to be removed from the attachment / detachment hole of the substrate, the operation plate needs to be pulled outward by the fingertip or the like and slid outward, which makes it difficult to operate. There is.

[0004]

[Problems to be solved by the device]

 It is an object of the present invention to provide a binding tool for paper or the like, which is easy to operate to allow the free end of the ring to escape from the attachment / detachment hole of the substrate.

[0005]

[Means for Solving the Problems]

 The above-mentioned problem is solved by the binding device for paper or the like of the present invention, that is, by arranging a plurality of rings 1 having a substantially inverted U shape in parallel and providing a common mounting shaft 3 at one end of these rings 1. The other end is a free end, a hook 4 is provided on a free end of a part of the ring 1, and the mounting shaft 3 is rotatably assembled to one end in the width direction of the board 2 and the width of the board 2 is At the other end in the direction, a free end of the ring 1 having the above-mentioned hook 4 is inserted and provided with a detachable hole 5, and at both ends in the longitudinal direction of the substrate 2, the detachable hole 5 is opened and both end faces are formed. A hollow chamber 6 opening to the inside is provided, and a push button 7 is fitted in the hollow chamber 6 so as to be retractable, and the push button 7 is inserted into the attachment / detachment hole 5 of the substrate 2 with the push button 7 protruding outward. Locks on the hook 4 at the free end, and the push button 7 inside The push button 7 is integrally provided with a claw piece 8 for releasing the free end of the ring 1 when it is pushed, and when the free end of the ring 1 is inserted into the attachment / detachment hole 5. When the projection 12 provided on the mounting shaft 3 of No. 1 is deformed and the push button 7 is pressed to release the free end of the ring 1 as described above, the elastic restoring force causes the mounting shaft 3 to rotate in the opposite direction. This can be solved by a binding tool such as a paper characterized in that an elastic piece 13 for automatically escaping the free end of the ring 1 from the attachment / detachment hole 5 is provided on the substrate 2.

[0006]

【Example】

 Hereinafter, the illustrated embodiment of the present invention will be described. First, reference numeral 1 is a ring made of plastic and having a substantially inverted U shape. A plurality of the rings 1 are arranged in parallel, and a common mounting shaft 3 is integrally provided at one end thereof so as to be orthogonal to each other.

Next, reference numeral 2 is also a long plate-like substrate made of plastic. A bearing groove 9 (see FIG. 2) is provided on one side surface of the substrate 2 in the width direction, and the mounting shaft 3 of the ring 1 is rotatably fitted in the bearing groove 9. A ridge 10 for preventing the mounting shaft 3 from coming off is provided at a required portion of the inlet of the bearing groove 9.

The end of the ring 1 on the opposite side of the mounting shaft 3 is a free end. The free ends of the ring 1 located at both ends of the mounting shaft 3 are slightly longer than the free ends of the ring 1 in the middle, and hooks 4 are provided there.

The other end of the mounting shaft 3 is located on the other end of the board 2 in the width direction, that is, on the opposite side of the one end where the bearing groove 9 is provided, and on the upper surfaces of both ends in the longitudinal direction of the board 2. A free end having a hook 4 of the ring 1 is provided with an attachment / detachment hole 5 into which the free end can be inserted and removed. At the position corresponding to the free end of the ring 1 in the middle part, a recess 11 is provided in which the free end is inserted and which is self-extracting.

The free end of the ring 1 is inserted into the attachment / detachment hole 5 or the concave portion 11 of the substrate 2 when the attachment shaft 3 rotates inward, and the attachment / detachment hole 5 or the depression portion is inserted when the attachment shaft 3 rotates outward. Although it escapes from 11, when the mounting shaft 3 is rotated inward, before the free end of the ring 1 is completely inserted into the attaching / detaching hole 5 or the recess 11, as shown in FIG. The protrusion 12 provided in the central portion abuts on the elastic piece 13 provided on the edge of the bearing groove 9 on the upper surface of the substrate 2. Then, when the free end of the ring 1 is completely inserted into the attachment / detachment hole 5 or the recessed portion 11, the protrusion 12 of the mounting shaft 3 pushes the elastic piece 13 of the substrate 2 to slightly deform it, and the elastic piece 13 is attached by the restoring force. The shaft 3 is kept in a biased state so as to rotate in the opposite direction.

Hollow chambers 6 are provided at both ends of the substrate 2 in the longitudinal direction so as to communicate with the attachment / detachment holes 5 and open at both end faces. A push button 7 made of plastic is fitted in the hollow chamber 6 so as to be retractable. The push button 7 is integrally provided with a claw piece 8, a wavy curved spring piece 14, and an elastic protrusion 15. The push button 7 is urged in the direction of coming out of the hollow chamber 6 by abutting the tip of the spring piece 14 against the inner wall of the hollow chamber 6, but the elastic projections 15 thereof are arranged at the substantially center of both ends of the substrate 2. It is fitted into a vertical hole 16 provided on the upper surface of the part to prevent it from coming off. The claw piece 8 is movably positioned below the attachment / detachment hole 5 into which the free end of the ring 1 is inserted, and as shown in FIG. 3, when the push button 7 is projected outward, the attachment / detachment hole 5 is inserted. The free end of the ring 1 is prevented from coming out from the attachment / detachment hole 5 by being locked to the hook 4 provided at the free end of the ring 1 inserted into the push button 7 so as to compress the spring piece 14. When is pushed inward, it is disengaged from the hook 4 to release the free end of the ring 1, as shown in FIG. By integrally providing the push-button 7 with the wavy curved spring piece 14 as described above, it is not necessary to assemble a separate spring for returning to the push-button 7, and the number of parts can be reduced.

When the push button 7 is pushed inward as described above to release the free end of the ring 1, the substrate 2 which has been deformed by being pushed by the projection 12 provided on the mounting shaft 3 of the ring 1 as described above Since the mounting shaft 3 rotates outward due to the restoring action of the elastic piece 13, the free end of the ring 1 automatically comes out from the attachment / detachment hole 5 and the recess 11, and the ring 1 opens to the substrate 2. . Therefore, the troublesome work of picking the ring 1 with a finger and pulling it out from the attachment / detachment hole 5 is unnecessary.

[0013]

[Effect of the invention]

 The present invention is as described above. When the free end of the ring 1 is pulled out from the attachment / detachment hole 5 of the substrate 2 to open the ring 1, the push buttons 7 provided at both ends of the substrate 2 are simply pushed inward. Since it is good, the operation is extremely simple and easy as compared with the conventional example, and there is an advantage that it is easy to use.
