Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge type binder binding device, and more particularly to a structure for locking the opening of a closed binder binding device.

[0002]

2. Description of the Related Art FIG. 10 exemplifies a hinge type binder binding device 2 which has been conventionally used. The binding device 2 is generally a support member or a flat spring member 4 (FIG. 1) for fixing to the back side of a cover member (not shown) and for elastically performing a hinge operation.
1)) and two longitudinal members 6 and 8 elastically hinged by the flat spring member 4, each of the two longitudinal members 6 and 8 comprising: A plurality of semi-annular members are provided which, when they are closed, fit together and form a plurality of binding rings 10 and at each longitudinal end of the two longitudinal members 6 and 8. Finger-holding portions 12 and 14 of substantially the same shape are provided for opening the binder binding device 2, respectively. The binder binding device 2 having the above configuration is opened by pulling the finger hooks 12 and 14 provided at the respective ends in the longitudinal direction toward each other with a finger or the like, and the semi-annular member in the opened state is also retained. It can be closed by pulling it toward each other with a finger or the like. However, when a large amount of a document or the like is closed in the binder binding device 2, the weight thereof becomes a load for opening the finger hooks 12 and 14, so that the binder binding device 2 is externally placed there during transportation or the like. When a physical impact is applied, even if the impact is slight, the flat spring member 4 is opened against the spring biasing force, and a situation in which documents and the like that have been carefully bound are scattered often occurs. ..

[0003]

SUMMARY OF THE INVENTION The problem to be solved is a novel binder binding device provided with a locking means that does not open even if a large amount of documents are closed by an external impact on the documents during transportation. It is to provide the structure.

[0004]

SUMMARY OF THE INVENTION In accordance with the invention, two longitudinal members are coupled in a resiliently hinged manner and the two longitudinal members are hingedly supported. And a first hole formed in the longitudinal member along a hinge portion of the longitudinal member. Similarly, a second hole is formed at a position corresponding to
A wall portion of the second hole having a single or a plurality of grooves formed therein in a generally horizontal direction, and at least one protrusion capable of selectively engaging with the groove of the second hole; There is provided the binder binding device, wherein a locking member having a lever means is inserted through the second hole and rotatably supported in the first hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to FIGS. FIG. 1 illustrates a lock body 10 according to the present invention. The locking body 10 has a generally cylindrical shape, and a lower end portion thereof is elastically fitted into a first hole, that is, a hole 14 formed in an outer supporting means of the binder, that is, a flat spring member 12. And then a bearing means 16 which is rotatably supported therein.
Are formed. The bearing means 16 generally includes an upper flange portion 18 and a lower flange portion 20 as shown.
And a groove portion 22 between them. Further, a pair of projecting portions 24, 24 is formed at a position close to the upper end portion. The projecting portions 24 are provided so as to project radially outward in directions opposite to each other by substantially the length of the flange portion. On the other hand, the upper flange portion 18 is integrally formed with a lever means 26 for rotating the lock body about its axis.

2 to 4 show a state in which the locking body 10 is attached to the binder binding device 28 and an operating state thereof. In the present invention, a second hole, or hole 34, formed along the hinge-acting portion of the two longitudinal members 30 and 32 forming the binder device is shown in FIGS. As is best shown in FIG. 1, one or more partially horizontal grooves 36 are formed. The groove 36 is the lock body 10.
Of the projections 24, 24 of FIG. 2 are in a substantially snug engagement with the projections 24 when they are orthogonal to the two longitudinal members 30, 30 as shown in FIG.
0 means lever means 26, as indicated by the arrow a in FIG.
Is rotated by approximately 90 ° so that when the two projecting portions 24 are brought to a position parallel to the two longitudinal members, they are dimensioned and positioned so as to come out of the groove 36. Properly formed.

With this structure, as shown in FIG. 3, in the state where the groove 36 and the protruding portions 24 are engaged with each other, the two longitudinal members 30 and 30 are, as described above, the binder binding device. A large amount of heavy documents, etc. are bound in the space, and some external shock is applied in that state, which causes arrow C.
Even if a large load is generated in the direction indicated by, rotation of the two longitudinal members in the direction of arrow C with the position 38 as a fulcrum can be physically prevented. Further, when the binder binding device is opened when it is necessary, as described above, the lever means 26 is rotated approximately 90 ° in the direction of arrow a as shown in FIG. Disengaged with
Thereby, the binder binding device can be easily released as shown in FIG.

5 to 9 illustrate a lock body 100 according to another embodiment of the present invention. The lock body 100 is the lock body 1 described above.
Similarly to 0, the support means 160 for elastically fitting into and supporting the outer support means of the binder binding, that is, the hole formed in the flat spring member, and the lock body 100 are fitted and supported in the hole. The lever means 260 is provided for rotating in a limited range in this state. However, in the locking body 100, the portion above the lever means 260 has a shape like a cylinder partially cut away at a parallel position along the longitudinal direction as shown in the drawing. In this case, a plurality of generally parallel grooves 300 are formed at positions corresponding to the protruding portions 24 of the lock body 10. These grooves 300 engage and disengage with correspondingly shaped grooves 310, which are partially formed in the two longitudinal members 30 ', 30' of the binder binding 28 ', respectively, in a manner similar to the previous embodiments. By doing so, the same effect as the lock body 10 can be obtained. Preferably, the groove 300 may be slightly tapered upwards, as illustrated in FIG. 9, while the groove 310 may be correspondingly tapered downwardly, thereby providing locking as previously described. The action can be made more advanced. Although the present invention has been described above with reference to specific examples, it should be understood that many modifications can be made within the present invention.

[0009]

By virtue of the above characteristics, the binder binding device of the present invention has the advantage that even if the bound paper sheet is considerably thick, and thus the weight of the bound paper sheet is considerably large, a slight external impact is applied thereto. With the addition of, it will not be released easily.
