Description

Snap button apparatus {Snap button apparatus}

The present invention relates to a snap button, and more particularly, to a snap button made of a simple structure but having a shape that can be easily separated by a user's intention while firmly maintaining a coupling force between a male button and a female button.

In general, a snap button, also called a snap button or a snap button, is installed at opposite positions on an opening to close an opening formed in a product such as clothing, a bag, or a shoe, and faces when an external force is applied. They are designed so that they can fit into each other.

As shown in FIG. 1, a conventional snap button has female buttons 10a and sub-buttons 10b that can be coupled and separated from each other, and snaps for fixing each of the female buttons 10a and sub-buttons 10b to fabric. (20a) (20b), while forming coupling holes (12a) (12b) at the center of the female button (10a) and the sub-button (10b), the snap (20a) (20b) has the coupling It consists of a structure with cylindrical coupling rods 22a and 22b passing through holes 12a and 12b.

At this time, an elastic ring is embedded inside the female button 10a to prevent the middle weight 10b from being separated by coming into contact with the outer circumferential surface of the fixing protrusion formed on the middle weight 10b.

Looking at the process of attaching such a conventional snap button to clothing, bags, shoes, etc., first, the positions where the female button 10a and the sub button 10b are to be fixed on the fabric of clothing, bags, shoes, etc. are marked with markings, respectively. After that, a hole is drilled at the marking position with a punch, and the coupling rods 22a and 22b of the snaps 20a and 20b are inserted into the holes, respectively, and the coupling rods 22a of the snaps 20a and 20b (22b) after aligning and inserting the female button 10a and the male button 10b's coupling holes 12a and 12b, respectively, the snaps 20a and 20b protruding above the coupling holes 12a and 12b. By hitting the coupling rods 22a and 22b with a punch or the like to expand and close the coupling rods 22a and 22b, the female buttons 10a and the male buttons 10b are fixed to the fabric, respectively.

Therefore, when combining them, after positioning the fixing protrusion of the sub-button 10b to coincide with the coupling hole 12a formed in the female button 10a, and then pressing the sub-button 10b toward the female button 10a, the fixing protrusion engages. While being inserted into the hole 12a, the elastic ring embedded in the female button 10a is tensioned by the end of the fixing protrusion, and then placed on the concave outer circumference of the fixing protrusion and compressed, so that it comes into close contact with the outer circumferential surface of the fixing protrusion, thereby forming the female button 10a and The sub-weight 10b is integrally coupled.

Of course, when the snap button is separated, if the female button (10a) is fixed by pulling the fabric, the fixing protrusion is separated from the elastic ring and is easily separated.

Even if these female buttons (10a) and sub-buttons (10b) are installed with their coupling positions reversed, there is no problem in operation. Details of these snap buttons are described in Korean Utility Model Registration No. 20-0183274 and Utility Model Registration No. 20-0288149, which are the following patent documents.

However, in the case of the conventional male screw 10b for a snap button, as shown in FIG. 1, since the coupling hole 12b is exposed to the outside in a state separated from the female screw 10a, the appearance of the male screw 10b is structurally not beautiful. There was a problem that could not be achieved, and as a result, there was a problem that the luxury of the male screw 10b could not be produced.

In particular, conventional snap buttons had to form protruding coupling holes 22b and coupling rods 22a in order to increase their coupling force, or arrange other members used for coupling.

However, these snap buttons have a problem in that they deviate from the purpose of simple use, such as adding additional configurations or complicating shapes for the purpose of increasing bonding force.

It is formed to have a lower convex inner circumferential surface protruding in the direction.

In addition, the second upper button of the second snap button is formed in a shape in which the thickness gradually decreases toward the outside from the center, and is configured to have an upper bent portion in which a direction extending outward is inclined downward. The second lower button of the second snap button has a lower convex outer circumferential surface formed of a shape that can be inserted into the lower concave inner circumferential surface and a lower concave outer circumferential surface formed of a shape that can be inserted into the lower convex inner circumferential surface. is formed

With the proposed snap button device, tight coupling can be achieved without using a separate coupling member for coupling between snap buttons, and even if the user applies force to separate the buttons to release them, separation between the buttons is easy. There are advantages that can be achieved.
