Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deformed annular key chain formed into an arbitrary shape such as a rectangle, a triangle, or a circle.

Conventionally, a ring-shaped key holder has both ends formed into hooks for fitting, or formed into a key shape for fastening. In the present invention, by pressing one of a pair of tongue-like protrusions formed from an elastic metal and provided at both ends, the sliding tube is moved in the direction of the tongue-like protrusion in the opposite direction. The key can be removed simply by exposing the joint part and pulling the joint part, which is only in contact, up and down.

An embodiment of the invention will be described with reference to the figures.

1 is a key chain main body made of elastic metal. The keychain main body 1 is formed by bending an elastic metal rod into a rectangular shape with rounded corners in plan view when both ends are in contact with each other. The cross section is rectangular with a wide width and a thin thickness. Close to both end surfaces of this main body 1,
In the figure, the tongue-shaped punched protrusions 2 and 3 are provided symmetrically upward and downward, but both tips of the tongue-like protrusions 2 and 3 are formed so as to be gradually inclined from the base and always protrude from the plane. . This can be raised or lowered due to the elasticity of the metal. 4 is a sliding tube, which is attached to the key chain main body 1 so as to be freely slidable. This sliding tube 4 includes a pair of tongue-shaped punched protrusions 2 provided on the main body 1;
Holes 5 and 6 are bored in the same shape and size as 3 and in the same position.

In the key holder according to the present invention having the above structure, the tips of the tongue-like protrusions 2 and 3 of the main body 1 are inserted into the holes 5 and 6 of the sliding tube 4, and the sliding movement of the sliding tube 4 is controlled. It can be used as a stopper for keychains. At this time, since the tongue-like protrusions 2 and 3 that protrude symmetrically are inserted into the holes 5 and 6 of the sliding tube 4, the sliding tube 4 can be moved in any direction in the longitudinal direction of the main body 1. Can't move. That is, no matter which direction the sliding tube 4 is pushed, the tip of the tongue-shaped piece 2 or 3 hits the inner peripheral wall of the hole 5 or 6 and the sliding tube 4 does not move. On the other hand, if one of the tongue-like protrusions 2 or 3 is pressed with a finger to make it flat, the sliding tube 4 will be unlocked and the other tongue-like protrusion 3 (or 2) will be released. ) can move the transmissive tube 4 in the direction. The tongue-like protrusion 3 (or 2) in the other direction is gradually pressed from the base as the sliding tube 4 moves, and forms the same plane as the surface of the main body 1, and the sliding tube 4 is never locked. do not have. When the movement is finished in this manner, the contact portions on both end surfaces of the main body 1 are exposed. Next, main body 1
The key can be inserted and removed by shifting it to either of the contact areas. By this reverse operation, the tongue-like protrusion 2 or 3 is locked in the hole 5 or 6 by the elasticity of the metal, and becomes a stopper as described above.

Although both ends of the main body 1 are in contact with each other in this embodiment, they may be brought close to each other with a small space for insertion and removal of the key. In any case,
The abutting or proximate portions of both end faces of the main body 1 are surrounded and protected by the sliding tube 4, and the tips of the tongue-like protrusions 2 and 3 protrude from the plane. It locks the holes 5 and 6 of the sliding tube 4 and also functions as a stopper, providing excellent safety and durability as a key holder. Also, if you press either of the tongues 2, 3 with your finger and move the sliding tube 4, the lock will be released, and the tips of the tongues 2, 3 will return to their protruding state due to the elasticity of the metal. Therefore, it is simple, quick and easy to use. Further, the cross section of the main body 1 is not a flat rectangle as in this embodiment, but may of course be circular in cross section.

In the embodiment, the flat surface of the main body 1 is a hollow rectangular shape, but it may also be square, and as illustrated in FIGS. 7 and 8, it may be circular or circularly deformed, etc., so that the transmissive tube can move the required distance. Any shape is fine.

In the above embodiment, a pair of tongue-like protrusions 2 and 3 were provided, but in the present invention, at least one protrusion of an appropriate shape whose tip protrudes from the plane of the main body 1 is provided, regardless of the shape or number of the protrusions. Bye. Even in this case, by appropriately selecting the protruding shape of the tip of the projection and the hardness of the material, when the projection is fitted into the hole 5 or 6 of the sliding tube 4, the sliding tube 4 Produces the effect of not moving unnecessarily.

Further, in the above embodiment, the device is made of metal, but it may be made of an appropriate material such as plastic. At least the tip of the protrusion protrudes all the time, and by applying pressure, the tip becomes flush with the main body, and the locking can be released.
