Description

[Detailed description of the invention] This invention relates to a button fastener that allows buttons on clothing to be attached without sewing them with thread.

Conventionally, various button fasteners of this type have been devised in which the buttons are attached to clothing without being sewn with thread.

However, these conventional button fasteners were fabricated by folding back a metal piece or punching out a metal piece, so they had the drawback of being labor-intensive and expensive to manufacture.

Furthermore, these button fasteners are constructed without considering the state in which they are locked with the button, and in order to attach the button to clothing, the button fastener must be forcefully pushed into the button's locking ring. As a result, the locking ring of the button became loose and it took time to attach the button.

This invention eliminates the drawbacks of the conventional examples, and aims to be easy to manufacture and inexpensive by molding elastic synthetic resin, and to be resistant to button locking rings. To provide a button fastener that can be attached without applying force.

Hereinafter, the configuration of this invention will be explained with reference to the drawings showing examples.

Reference numeral 1 designates a button fastener of this invention, which is made of elastic synthetic resin and has a locking part 2 at the center and abutting parts 3 on both sides.

The locking part 2 is formed by bending the central part of the main body of the button clasp 1 to have a narrow width and a hook-shaped cross section.
It is designed to fit into the locking ring 5 of the button 4.

The abutting portion 3 is formed as a projecting piece having shoulders 6 on both sides of the locking portion 2, and at least one of the abutting portions 3 is opened at the center to form a hole 7, and the abutting portion 3 has a hole 7 at its center. A cutout groove 8 is provided that enters the locking portion 6 from the punch hole 7.

Moreover, FIGS. 4 and 5 show other embodiments of the button fastener of this invention, in which both abutment parts 3 formed on both sides of the locking part 2 are opened in the center to form a punch hole 7.
At the same time, a cutout groove 8 is provided that communicates from the hole 7 to the locking portion 2.

The button fastener of this invention is constructed as described above, so in order to use it, as shown in Fig. 3, when putting the front of the garment together, a hole is made in the fabric 9 that lies underneath. The locking ring 5 of the button 4 is inserted into the small hole 10, and the contact part 3 of the button fastener 1 is fitted into the locking ring 5 from the back side of the fabric 9.

At this time, when the shoulder 6 of the abutment part 3 is pinched or pushed in with your fingers, the abutment part 3 is easily deformed because it is provided with a punch hole 7 and a notch groove 8, and a strong force is applied to the locking ring 5 of the button 4. It gets stuck even if it doesn't work.

Then, when the button fastener 1 is fitted to the position of the locking part 2, the abutment part 3 is restored to its original state.

Furthermore, if the holes 7 are formed in both of the pads 3 as in other embodiments, the locking ring 5 of the button 4 can be fitted from either pad 3.
Furthermore, since the cutout groove 8 is provided in this case as well, the abutment part 3 can be easily deformed and can be fitted into the locking ring 5 of the button 4 without applying strong force.

As mentioned above, the button clasp of this invention can be easily manufactured by molding synthetic resin, and can be attached without applying strong force to the locking ring of the button. Excellent practical effect.
