Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener and an accessory.

[0002]

2. Description of the Related Art Conventional fasteners used in accessories such as necklaces are generally constructed by combining a ring-shaped retaining ring that cannot be opened and closed and an openable / closable retaining ring or an openable / closable hook. Met.

However, since this type of stopper is extremely small, the attaching and detaching operation of the above-mentioned retaining ring structure or hook structure is troublesome. In particular, when connecting or removing the retaining ring at a position outside the field of view, it is very difficult to attach and detach the retaining ring. In the case of a bracelet, which is another example of a jewelry accessory, the operation of attaching and detaching the fastener must be performed with one hand, which is more troublesome and difficult than a necklace.

[0004] As means for solving such problems,
Conventionally, various stoppers have been proposed. For example, Japanese Utility Model Registration No. 3042071 discloses a spherical stopper, in which an elastic member is inserted into the inside and held by the elastic member so that the decoration chain does not come off. As the internal elastic member, a spring, rubber, sponge, or the like is shown.

However, in this prior art, since the chain is directly held by the elastic member, the chain must be passed through the elastic member housed in the stopper. Such an operation is extremely difficult.

Moreover, the elastic member can only correspond to a chain having a specific thickness and shape, and when the thickness, structure, shape, and the like of the chain change, it is possible to adapt to the change in an optimal state. Difficult and lacks versatility.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a stopper which can reliably and easily perform the attaching / detaching operation, and an accessory using the same.

[0008] Another object of the present invention is to provide a highly versatile stop.

[0009]

In order to solve the above-mentioned problems, a stopper according to the present invention comprises a first connecting member and a second connecting member.
And a connecting member.

[0010] The first coupling member includes an outer shell and an elastic body. The outer shell has an outer wall, a hollow portion, and a hole. The hollow portion is surrounded by the outer wall.
The hole passes through the outer wall and communicates with the hollow portion.
The elastic body has a through hole communicating with the hole, and is built in the hollow portion.

[0011] The second coupling member has a projection and a base. The protrusion includes a neck and a bulge. The neck is supported by the base. The bulge is provided on the neck, the maximum outer diameter is the outer diameter of the neck,
And it is larger in diameter than the inner diameter of the through hole of the elastic body. The first coupling member and the second coupling member can be coupled to each other.

As described above, the outer shell included in the first coupling member has a hole, and the hole penetrates the outer wall and communicates with the hollow portion. An elastic body is built in the hollow part,
This elastic body has a through hole communicating with the hole of the outer shell. On the other hand, the second coupling member has a projection. Therefore, the second
A simple operation of introducing the projection provided on the coupling member through the hole of the outer shell constituting the first coupling member into the interior of the outer shell, and penetrating the inside of the through hole of the elastic body. By
The first coupling member and the second coupling member can be easily coupled.

[0013] The projection provided on the second coupling member includes a bulging portion, and the bulging portion has a maximum outer diameter larger than an inner diameter of the through hole of the elastic body. Therefore, when the swelling portion is passed through the through hole of the first coupling member, the swelling portion is hung on the elastic body outside the inner diameter of the through hole of the first coupling member. , Receiving its elastic force. For this reason, the second coupling member is stably and reliably hooked to the first coupling member while receiving the elastic buffering action of the elastic body.

In order to release the connected state of the first connecting member and the second connecting member, the first connecting member and the second connecting member are released against the elastic holding force of the elastic body.
It is only necessary to pull out the projection from the elastic body. Therefore, the first
The uncoupling operation between the coupling member and the second coupling member,
It can be performed very easily.

Further, since the first coupling member has an outer shell and the second coupling member has a base, various types of the outer shell and the base can be selected depending on the design of the shape and structure of the base. Products, especially accessories, can be realized. The shapes and structures of the outer shell and the base can be arbitrarily designed as long as the above-described basic configuration is maintained.

When the elastic body 71 is an O-ring and the maximum outer diameter before insertion into the hollow portion 11 of the outer shell 5 is larger than the maximum inner diameter of the hollow portion 11, the elastic body 71 is Since it is arranged in the hollow part 11 in a compressed state, the neck part 2
7 receives a strong crimping force from the inner wall surface of the through-hole 15 and is in a tightened state.

Further, the distance L2 from the upper surface of the lid 19 to the lower surface of the elastic body 71 is set to be equal to or greater than the distance L1 from one end of the neck 27 to the other end thereof. Dip into the bottom. Therefore, the protrusion 23 is pushed from the elastic body 71 in the direction of the arrow a1, and the elastic body 71
It is pushed from the projection 23 in the direction of arrow a2. Therefore,
The first coupling member 1 and the second coupling member 3 are stably positioned in this state.

First connecting member 1 and second connecting member 3
Can be released by simply pulling out the projection 23 from the elastic body 71 in the direction of arrow a2 (see FIG. 2) against the elastic holding force of the elastic body 71. For this reason, the uncoupling operation between the first coupling member 1 and the second coupling member 3 is performed.
It can be performed very easily.

Further, since the first connecting member 1 has the outer shell 5 and the second connecting member 3 has the base 25, the shape, structure, etc. of the outer shell 5 and the base 25 are designed. In response to the,
Various products, especially accessories, can be realized. The shapes, structures, and the like of the outer shell 5 and the base 25 can be arbitrarily designed as long as the above-described basic configuration is maintained. Next, an example of use of the stopper according to the present invention will be described.
