Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastening rivet which can fasten a plurality of plate-like members so as to be slidable with each other. The present invention relates to a fastening rivet configured to be discarded or reusable.

[0002]

2. Description of the Related Art For example, it is well known that fastening rivets are widely applied to a file for organizing documents and the like which are used on a daily basis in order to integrally connect a mount and a binding.

[0003] However, this type of fastening rivet is usually formed of a screw member having a single structure, and after the screw member is inserted from the outside of the mount into a rivet hole formed in the mount and the metal fastener, By caulking the leading end of the screw member, the mount and the metal fitting are connected.

[0004]

However, between a plurality of members connected by such a fastening rivet, there is a demand for an adjustability that allows sliding of any one of the members. In addition, with the aging of some components due to aging, it is required that some components be discarded and other components reused. It is desired that a fastening rivet can be easily separated and reused.

That is, the conventional fastening rivet has a structure in which all the connections between its members are fixed.
However, the "fixed connection" is, for example, in the file for organizing documents, first of all, it is impossible to change and adjust the mounting position of the binding member with respect to the backing sheet. At the time of recycling, it was very difficult or practically impossible to separate waste (backing paper) from collected products (binders, etc.).

[0006] Therefore, in the conventional fastening rivet, there is a demand for an improvement in the adjustability or re-separability between the connecting members depending on the field of use.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fastening rivet which can easily perform a fastening for enabling relative position adjustment between connecting members and can be separated and discarded or reused.

[0008]

In order to achieve the above object, a fastening rivet according to the present invention comprises a screw member having a mounting head at one end and a first flange at the other end. A second flange is provided at a middle portion of the screw member.

In this case, the screw member forms a shaft portion whose diameter changes in two steps with respect to the other end portion, and the outer periphery of the shaft portion is caulked horizontally on the large diameter side of the step portion at the step portion. 2
A circumferential groove having a required depth for forming the first flange is formed, and a cylindrical hole having a required depth for forming the first flange is formed on the small-diameter end portion by caulking the outer periphery horizontally. Can be.

Further, the second flange and the first flange of the screw member are fitted and locked in a locking hole provided in the first plate-shaped member, and the mounting head and the second flange are connected to each other. A flange is slidably fitted in a guide groove of a second plate-like member, and the first plate-like member is relatively moved with respect to the second plate-like member along the guide groove. Can be configured to be movable.

As an alternative, the screw portion forming the second flange and the third flange is constituted by a ring member having flanges at both ends, and has a locking step for engaging with the ring member. Alternatively, it may be constituted by a caulking screw member having a first flange which is inserted into the ring member at its tip end, and caulks its protruding end and is integrally connected.

In this case, the ring member is fitted and locked in a locking hole provided in the first plate member, and the caulking screw member is slid with respect to the guide groove of the second plate member. The first plate-shaped member may be configured to be movably fitted and relatively movable along the guide groove with respect to the second plate-shaped member.

Further, a displacement portion is provided in a part of the locking hole of the first plate-like member, and the ring member is temporarily fixed and held by using the displacement portion. While inserting the caulking screw member from the hole of the plate-shaped member of No. 2,
The ring member and the caulking screw member can be integrally connected by caulking the protruding end of the caulking screw member.

[0014] A first opening hole having a diameter larger than the outermost diameter of the fastening rivet is provided adjacent to the locking hole of the first plate-like member. At one end of the guide groove, a second opening having a diameter larger than the outermost diameter of the fastening rivet is provided corresponding to the first opening, and a fastening rivet is inserted through each of the opening. A configuration in which the first plate-shaped member and the second plate-shaped member are combined can be adopted.
