Description

[Detailed description of the invention] The present invention is designed so that once the key is hooked, it will not come off unexpectedly unless it is forced to be removed in a direction other than a certain direction, is firmly inserted, and is lightweight. The object of the present invention is to obtain a key chain that can be used as a ring and has excellent advantages such as being simple in structure and inexpensive to manufacture.

Next, an example of implementing the present invention will be explained with reference to the drawings.
A is a key chain that doubles as a ring, and is usually formed by cutting out a thin piece of steel using a press.

To explain the structure of the ring key chain key below, 1
is the head, 2 is a fitting hole formed in the head 1, and furthermore, in the overall shape of the key chain eye, one end edge 3 located slightly above the center is cut into a notch that cuts inward. form 4.

Then, from the end edge 3a on the opposite side to the above, the end extends downward by a predetermined length, is further bent into a curved shape, and gradually extends upward, and is bent to reach the notch 4. A band-shaped surrounding portion 5 having a shape slightly smaller than the width of the notch portion 4 is formed, and the surrounding portion 5
It is assembled with the bent end inserted.

Reference numeral 6 denotes a hollow portion formed by punching the inside of the surrounding portion 5.

However, when not forming the notch 4 as described above, one edge 3 slightly above and below the center of the overall shape may be cut, or in this case, a predetermined cutout may be made from the opposite edge 3a. The band-shaped surrounding portion 5 may be formed by further bending downward by a length of , curving upward from below, and extending to a height reaching the cut surface of the end edge portion 3 .

Furthermore, a recess 4a is formed in one end edge 3 of the connection with the head 1, extending to a position slightly above the center of the overall shape, and a recess 4a is formed at the end extending to a position slightly above the center of the overall shape, and a predetermined length It is bent downward, slightly curved, and then upward again, so that the end portion forms the concave portion 4a.
A band-shaped surrounding portion 5 is formed to be inserted therein.

7 is a stopper fixed to the cover 8 of the key chain, 9 is a screw, and 10 is a ring-shaped support in which the ring portion 11 of the stopper 7 is cut out and rotatably fitted.
0. Hang the key chain key ring made by this invention.

12 is a key, 13 is an adhesive part, and 14 is a decorative part.

To further explain the function of the present invention, when the ring key holder eye of the present invention is used as a ring, it is suspended from a support 10 as shown in the first figure.

However, in order to hang the key 12 on the key holder of the present invention, grasp the head 1 or the left edge 3a of the head 1, and use the fingers of the other hand to pull the upper right side of the surrounding part 5 towards you or forward. When pushed a little forcefully, the bottom part of the flat surrounding part 5 is used as a fulcrum, and as it goes upwards, it gradually opens to the largest extent, and in particular, the ends fitted in the notches 4 and 4a open up to the maximum extent. It becomes an open state away from the area.

When the above condition is reached, insert into the insertion hole 12a of the key 12,
When the end portion is inserted and the pressure is released once the end portion has been inserted, the end portion of the surrounding portion 5 fits into the notch portions 4, 4a.

Even when the key 12 inserted in this way is pulled in a suspended state, the ends of the surrounding part 5 are fitted into the notches 4 and 4a, and are located slightly above the center. Furthermore, the key 12 is prevented from moving accidentally by the edges of the notches 4 and 4a, so that it does not come off unexpectedly.

Also, to remove the key 12, remove the surrounding part 5 using the same process as above.
The key 12 can be easily removed by pressing the key 12 to release it.

(1) Since the present invention uses a press to form a thin steel plate into the shape described above, the material itself has strong elasticity, and the end of the surrounding portion 5 will not open unless it is pressed very strongly. By forming the inner side of the enclosing part 5 into a band shape as a hollow part 6, and by extending the end of the enclosing part 5 slightly above the center, etc., when the key 12 is hung, the enclosing part 5 is The end portions are reliably fitted into the notches 4, 4a and never open, so there is no risk of them coming off unexpectedly, and this has the excellent advantage of continuing to function as a key holder.

(2) Furthermore, the present invention allows the ends of the notches 4, 4a to
Since the key 12 is prevented from moving, it has the advantage of not being accidentally released.

(3) Furthermore, since the present invention is formed by stamping a thin steel plate using a press, the number of manufacturing steps is extremely small, which has the advantage of significantly reducing manufacturing costs.
