Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention relates to a loose-leaf type spelling mechanism such as a booklet, and in particular, spelling having a few C-shaped spelling portions parallel to each other. A coil, a spelling coil holder that can hold the spelling coil, and a cap that can be inserted into and locked at both ends of the spelling coil holder, and the like so that a book surface or the like can be surely spelled, and after combination. In regard to a spelling mechanism such as a loose-leaf book surface, the appearance of which is very orderly.

(Prior Art) Conventionally, there are many mechanisms for splicing loose-leaf type books and the like, for example, a spelling mechanism having a plastic binding coil, a binding mechanism having an openable metal ring for binding, and the like. To be

However, such a conventional spelling mechanism has drawbacks that it is easily loosened and that the edges of the pages of the page cannot be aligned. Further, there is a drawback that it is very inconvenient at the time of combination and removal, and it is easily disassembled especially when a heavy pressure is applied.

On the other hand, for example, Japanese Utility Model Publication No. 48-8308 discloses a binding mechanism including a binding coil, a binding coil holder, and a cap. The binding coil has a plurality of C-shaped binding portions arranged in parallel, and one ends of these binding portions are connected by a linear connecting portion. Further, the binding coil holder has an elongated rectangular shape, and has a groove along each of the long sides with which the free end of the binding portion of the binding coil and the connecting portion are engaged with each other. In addition, the cap is
The binding coil is mounted on the end of the binding coil holder to prevent the binding coil from coming off from the binding coil holder. The cap has protrusions to be inserted into the both recessed grooves of the binding coil holder, and has legs to be inserted into the central recessed groove between the both recessed grooves of the binding coil holder. There is. On this leg, projections that engage with the holes on both sides of the central groove are formed on both sides, and through holes for elastic deformation are formed between these projections.

With such a binding mechanism, binding and disassembling of pages on the page can be facilitated, and the appearance of the bound pages can be improved. However, in the one described in the above publication, in order to hold the cap on the spelling coil holder, the projections provided on both sides of the leg of the cap are engaged with the holes provided on the spelling coil holder. As the legs are elastically deformed and the projections are disengaged from the holes, the holding state of the cap is uncertain. Further, since the binding coil only engages with the concave groove of the binding coil holder and is not particularly related to the cap, the binding to the binding coil holder is uncertain. A splicing coil in which one ends of a plurality of C-shaped splicing portions are connected by a linear connecting portion must be manufactured by injection molding or press processing, which is cumbersome to manufacture and difficult to adjust the length.

(Problems to be solved by the invention) As described above, even in a loose-leaf type binding mechanism such as a binding coil, a binding coil holder, and a cap, the assembled state is weak and the binding coil is There was a problem that manufacturing was troublesome.

The present invention is intended to solve such a problem, and facilitates coupling and separation of each member in a loose-leaf type binding mechanism such as a loose leaf type book surface including a binding coil, a binding coil holder, and a cap.
