Description

[Detailed description of the invention] The present invention is designed so that even if external pressure from fingers or the like is applied to both edges of the key chain, the external pressure is simultaneously applied to both ends, thereby preventing the ends from opening unexpectedly. In addition, the curved and symmetrically swollen downward concave portion formed at the end of one of the band-like edges improves the feel of the finger. The purpose of this object is to obtain a key chain that can be used as a ring, which has excellent properties such as smooth operation when opening and closing, light weight, simple structure, and low manufacturing cost. be.

To explain the content of the present invention created to achieve such an objective, the head 1 having the insertion hole 2 and one of the connecting band-shaped end portions 3 are slightly outwardly moved from the center of the overall shape. It stops at a position slightly higher than that, and its end is curved to form a symmetrically bulging downward recess 4, and the other band-shaped end 3a connected to the head 1 is It has an end that extends outward by a predetermined length, further curves slightly inward, and then bends upward again into a 〓 shape, and that fits into the downward recess 4 of one end edge 3. A band-shaped surrounding part 5 is formed, and one edge part 3 and the band-shaped surrounding part 5 are connected to each other.
This is a key chain that doubles as a ring and is made of a thin steel plate, and is characterized by having a hollow part 6 formed on the inside thereof, and having a cross-shaped shape when viewed from the side.

Next, an example of the implementation of the present invention will be described with reference to the drawings.
It is usually formed by cutting out a thin steel plate using a press. The structure of the ring-functioning key holder will be described below. 1 is a head, and 2 is a fitting hole formed in the head 1. 3 extends in a slightly curved shape outward from one side of the head 1, and has a curved and symmetrically expanded end at the extending end located slightly above the central part of the overall shape of the key chain eye. It is a band-shaped edge portion in which a downwardly directed concave portion 4 is formed, and a band-shaped edge portion 3a of the head 1 on the opposite side to the edge portion 3 is extended outwardly by a predetermined length, and further slightly It curves inwardly and upwardly again to form a band-shaped enveloping part 5 having an end that fits into the downward recess 4 of one end edge 3. 3 and the inside of the band-shaped surrounding part 5 are formed into a hollow part 6. 7 is the key, 8 is the insertion hole,
9 is a decorative part. To further explain the function of the present invention, the key 7 is attached to the ring key holder made by the present invention.
To hang it, grab the head 1 or the left edge 3a of the head 1, and use your other hand to push the upper right side of the surrounding part 5 toward you or forwards, and it will become flat. The bottom part of the enclosing part 5 is used as a fulcrum, and the enclosing part 5 opens widest as it goes upward. are separated and become open. When the above condition is reached, insert the key 7 into the insertion hole 8.
When the end of the surrounding portion 5 is inserted into the hole and the pressure is released after the insertion, the end of the surrounding portion 5 and the recess 4 of one end edge 3 fit together again, and when viewed from the side, they are aligned. It becomes like a thin sheet. Key 7 thus inserted
Even if you tow the key chain in a suspended state, the upper end of the surrounding part 5 is fitted into the recess 4, and the fitted part is located slightly above the center of the height of the key chain. Do not leave suddenly due to the reason for being there.

Further, in order to remove the key 7, the key 7 can be easily removed by pressing the surrounding portion 5 and opening the upper end of the surrounding portion 5 in the same process as described above.

(1) The present invention is as described above, and in particular, among the left and right end edges of the head, one of the band-like end edges is curved and symmetrically bulged downward. The other band-shaped end edge is bent into a shape and fitted into the recess, so even if external pressure is applied to the area near the recess to be fitted, the recess or the recess External pressure is not applied to only one of the ends that are fitted inside, but is applied to the entire body, so the recess etc. will not be opened unexpectedly and the hooked key will not come off. , it has the advantage of significantly increasing the so-called detachment prevention force of both end edges. Furthermore, since the concave portion of the present invention is curved and has a symmetrical bulging shape, even if fingers hit it, it does not get caught, giving a smooth feel and preventing damage to fingers, etc. It is also owned.

(2) 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.

Claims (1)

[Scope of utility model registration request] One band-shaped end edge 3 connected to the head 1 having the insertion hole 2 is slightly outwardly stopped at a position slightly above the center of the overall shape, and the end thereof is curved, A symmetrically bulging downward concave portion 4 is formed, and the other band-shaped end portion 3a connected to the head portion 1 is extended outwardly by a predetermined length, and is further curved slightly inwardly. It bends upward again into a shape and forms a band-shaped surrounding part 5 having an end that fits into the downward recess 4 of one end edge 3, and connects the one end edge 3 and the band-shaped surrounding part 5. This key chain made of thin steel plate and used as a ring is characterized in that a hollow part 6 is formed on the inside of a part 5 and the shape is square when viewed from the side.
