This ring file is composed of, for example, a cover 1 made of thick paper covered with vinyl leather and a binding tool 2 made of a metal material. The binding tool 2 uses a plurality of fasteners 3 on the inner surface of the spine cover 1a. It is fixed.

As shown in FIG. 2, the fastener 3 before fixing the binding tool 2 to the spine cover 1a is for maintaining the engagement member 4 and the engagement state of the engagement member 4 as shown in FIG. It is composed of a lock member 5. The engaging member 4 is the expanded head 4a.
A neck portion 4b, a through hole 4c penetrating the expanding portion 4a and the neck portion 4b, and a plurality of axial slits 4d formed in the neck portion 4b so as to be easily bent inward through the through hole 4c. And the elastic engagement portion 4 formed on the outer periphery of the free end of the neck portion 4b.
It consists of e. The lock member 5 has a shape that fills the through hole 4c so as to be inserted into the through hole 4c of the engaging member 4.

Here, in a state before the binding tool 2 is fixed to the spine cover 1a, the lock member 5 has the expanded head 4a of the through hole 4c.
It is coupled to the side opening via a coupling portion 3a. More specifically, the engagement member 4 and the lock member 5 are integrally molded of the same synthetic resin material, and can be handled as one component before the binding tool 2 is fixed.

On the other hand, the binding device 2 and the spine cover 1a are formed with a plurality of holes 7 and 8 having substantially the same diameter as the neck portion 4b so that the neck portion 4b of the engaging member 4 can be inserted therethrough.

Next, the procedure for fixing the binding tool 2 to the spine cover 1a will be described. First, the spine cover 1a and the binding tool 2 are superposed so that the corresponding holes 7 and 8 are aligned, and the holes 7 and
The neck portion 4b of the engaging member 4 of the fastener 3 is passed through the binder 2 from the spine cover 1a side through the fastener 8, and the elastic engaging portion 4e is engaged with the opening 7a of the hole 7 of the binder 2 to expand the head. Part 4
The spine cover 1a and the binding device 2 are sandwiched between a and the elastic engagement portion 4e. Then, the lock member 5 is pressed from the side of the expanding portion 4a of the engaging member 4 toward the through hole 4c, and the connecting portion 3
A is torn and the lock member 5 is inserted into the through hole 4c. As a result, the elastic engagement portion 4e cannot be reduced in diameter, and the engagement state of the engagement member 4 is prohibited from being released (removal prevention) (FIG. 3).

By integrally forming the lock member 5 on the side of the expanding portion 4a of the engaging member 4, the assembling can be performed from one direction, and the workability thereof can be improved.

Next, the procedure for disassembling the cover 1 and the binding tool 2 will be described. First, the tip 5a of the lock member 5 is pressed from the side opposite to the expanding portion 4a as shown by the arrow to separate the lock member 5. Then, for example, by inserting the tip of a flat-blade screwdriver between the base portion 2a of the binding tool 2 and the spine cover 1a and punching it, the elastic engagement portion 4e is bent inwardly through the through hole 4c to form the opening portion 7a. Release the engaged state. As a result, the engaging member 4 is disengaged from the holes 7 and 8, and the cover sheet 1 and the binding tool 2 can be disassembled.

In the above embodiment, the present invention is applied to the ring file, but the present invention is
It goes without saying that the same can be applied to other types of files such as pipe files. Further, in the above configuration,
Although the lock member 5 is integrally formed on the side of the expanding portion 4a of the engaging member 4, it may be integrally formed on the side opposite to the expanding portion 4a, that is, on the elastic engaging portion 4e. However, in that case, the elastic engagement portion 4e
It is advisable to adopt a structure in which they are partially connected so as not to hinder the operation of.
