Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pendant type key chain.

In general, keys for opening/closing doors and starting the engine of vehicles are often inconvenient to carry, or drivers often experience situations where they are unable to open/close the doors or drive the vehicle (crash) if they are left behind inside or outside the vehicle.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a key chain which can normally be used as a pendant, thereby avoiding the above-mentioned disadvantages.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

The pendant body 10 has a substantially truncated quadrangular pyramid shape, and a chain attachment rod 11 is slidably passed through the upper part of the pendant body 10.
A chain 12 for hanging around a person's neck or the like is connected to both ends of the attachment rod 11.

As a result, the pendant main body 10 does not easily turn upside down in a normal state when it is hung around a person's neck or the like.

The pendant body 10 has a square hole 1 opened on its top surface.
3, in which a sheath 15 containing a key 14 is arranged and fixed.

The key 14 is slidable within the sheath 15, and in the normal state it is inside the pendant body 10 as shown in the first figure, but if you hold the pendant body 10 in your hand and turn it upside down as shown in the second figure, It protrudes outside the pendant body 10.

The amount of protrusion of the key 14 to the outside of the pendant body is limited by the engagement between the key 14 and the sheath 15, thereby preventing the key 14 from falling off.

As shown in FIG. 4, a notch 16 is provided between both ends of the chain attachment rod 11 to face the side surface of the key 14 through a notch in the sheath 15, and the chain attachment rod 11 is slid into this notch 16. Accordingly, a leaf spring 17 that moves in and out is arranged between the key 14 and the chain attachment rod 11.

That is, the leaf spring 17 is fixed at one end to the chain attachment rod, and when the chain attachment rod is slid and biased as shown in the third and fourth figures, elastic deformation occurs between the key 14 and the chain attachment rod 11. The key 14 is restrained from sliding by biting into the key 14.

This prevents the key from being pulled into the pendant body when the key is inserted into the keyhole.

Note that the shape of the pendant body 10 can be arbitrarily selected, and the material of the pendant body 10 may be a transparent material or an opaque material, but when a transparent material is used, it is desirable to decorate the surface of the sheath 15.

Furthermore, the mechanism for preventing the key protruding from the pendant body from being retracted into the pendant body is not limited to the above-mentioned mechanism; for example, a chain attachment rod (a projection formed in a groove provided on the surface of the key) may be engaged and disengaged by sliding the chain attachment rod.

As described in detail above, the present invention f' (pendant type key chain according to the present invention) is convenient for carrying.
This has the practical effect of preventing you from leaving the key inside or outside the car and becoming unable to drive.

In addition, when the pendant type key chain is used as a spare key, the effect is even more remarkable, and if the driver leaves the key in the car and locks the door using the so-called keyless lock mechanism, the door can be easily locked. It has the effect of opening up.

It should be noted that the pendant type key chain according to the present invention does not necessarily have to be used for a vehicle, and it is clear that it can also be used for other keys.
