Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener such as a bag,
In particular, it is difficult to separate normally by inserting the male metal fitting into the female metal fitting, but it is possible to release the engagement with one touch, there is no protruding part on the surface, it is highly safe and it has an excellent aesthetic appearance. Regarding fasteners such as bags.

[0002]

2. Description of the Related Art Conventionally, for example, a hook has been used as a metal fitting for fixing a lid such as a bag to the main body, and a through hole is formed in a female metal fitting attached to the lid so that the male metal fitting attached to the main body can be used as a female metal fitting. It is known that the movable piece of the male metal fitting, which penetrates the through hole and protrudes outside the through hole, is rotated or bent to prevent the escape.

[0003]

In the case where the tip of the male metal fitting is projected from the through hole of the female metal fitting, in addition to the difficulty of separately manufacturing the movable piece and mounting it, the cost is high. , The male metal fittings projecting outward from the surface of the female metal fittings not only spoils the aesthetics, but also damages and is trapped in the crowds of vehicles and sales floors. However, they could not be engaged with one touch. In view of these circumstances, the present invention allows the male fitting to be engaged with the female fitting with one touch, the surface is flush and the appearance is excellent, and the cost of the member is low because there is no member such as the movable piece, and the protruding member etc. It was developed for the purpose of providing a fastener such as a bag without a bag.

[0004]

The present invention has taken the following technical means in order to solve the above problems and achieve the objects. That is, in a fastener made of a combination of a female metal fitting and a male metal fitting, the female metal fitting forms a fitting hole penetrating to the front and back in a central portion of a plane, and an engaging groove is formed on an inner peripheral surface of the fitting hole, The male fitting is formed in a tubular body of a size that fits loosely in the fitting hole of the female fitting, and a tip of the elastic locking projection that is elastically ejected outward by an elastic material inside the cylindrical main body. When the male fitting is inserted into the fitting hole of the female fitting,
The elastic locking projection comprises a stopper such as a bag configured to engage with the engaging groove on the inner peripheral surface of the fitting hole.

[0005]

The present invention constructed as described above has the following actions.

A. Attach the male fittings to the body such as the bag. At this time, the male fitting projects from the surface of the bag, for example, by 1 cm.

B. Attach the female fitting to the lid of the bag or the like. Since the fitting hole penetrates, the fitting hole portion also forms a through hole in the lid.

C. When the bag is closed, the fitting hole of the female metal fitting is located above the male metal fitting, but since the elastic locking projection of the male metal fitting protrudes outside the cylindrical main body peripheral surface of the male metal fitting, it remains as it is. Then, the male fitting is not inserted into the fitting hole.

D. Then push the female fitting from above,
The male fitting is inserted into the fitting hole because the elastic locking projection is retracted inward against the elastic force of the elastic material. Then, when the elastic locking projection reaches the engaging groove on the inner peripheral surface of the fitting hole, the elastic locking projection pushes its tip into the engaging groove by the elastic force of the elastic material. That is, since it is engaged, the female fitting does not come out of the male fitting.

E. When the male fitting is engaged with the female fitting, the end surface of the male fitting is flush with the end surface of the female fitting, so that the tip of the male fitting does not project as in the conventional case.
Not only does it look good, there is no danger of it getting caught or injuring anyone.

F. When the female metal fitting is lifted when opening the lid, the elastic locking projection is disengaged from the engagement groove and the engagement of both metal fittings can be easily released. However, since the engagement cannot be released unless the female fitting is correctly pulled in the axial direction (projection direction) of the male fitting, the engagement is unlikely to be released even if a force is applied to the fitting during use.
