Description

[Detailed explanation of the idea] This idea concerns improvements to buttons.

Generally, buttons are sewn onto clothing, but the threads often break and the buttons come off, or the buttons that come off are often lost.

Also, buttons with thread holes can be installed using a sewing machine, but those with a thread stopper ring on the back of the button cannot be installed using a sewing machine and must be done manually, resulting in high costs. Become.

In view of the above-mentioned drawbacks of the conventional button, this invention aims to provide a button that can be easily attached to clothing by eliminating the need for sewing with thread and consisting of a button body and a separate fastening member.

Examples of this invention will be described below based on the attached drawings.
FIG. 1 shows the button attached to clothing, and FIGS. 2 and 3 show enlarged views of its main parts, where A is the button body and B is the button fastening member.

The button body A has a rectangular short shaft rod 2 projecting from the center of the back surface of the main plate portion 1, and rack teeth 3 are formed on one wall of the short shaft rod over the entire length in the axial direction.

The button fastening member B has a rectangular through hole 5 in the center of a disk portion 4 made of a tough semi-hard synthetic resin material, through which the short shaft rod 2 of the button body can be inserted almost tightly. On the wall, a claw 6 that engages with the rack teeth 3 of the short shaft rod 2 is integrally connected to the disk portion 4 only on the upper side, and protrudes freely on the other side. It is possible to retreat.

In FIG. 3, 7 is a free gap between the claw 6 portion and the disk portion 4.

A pull knob 8 is attached to the back side of the claw so as to protrude from the circumferential outer surface of the disk portion 4.

In FIG. 1, reference numeral 9 indicates a decorative layer placed over the main plate portion 1 of the button body A.

This invention has the structure as described above, and this button consists of a button body A and a button fixing member B, and the button body A has a short shaft rod 2 with rack teeth 3 attached to the back side of the main plate. The button fastening member B is provided with a through hole 5 through which the short shaft rod 2 is passed, and the hole wall has a pawl 6 that engages with the rack teeth 3.The upper part is connected to the disc part 4, and the other side part is connected to the disc part 4. Since the buttons protrude freely, the button body A is positioned from the front side in the part where the small hole 11 of the edge 10 where the button is to be attached is located, and the short shaft rod 2 is passed through the button body A, and the button body A is placed on the back side of the edge 10. Just by facing the button fixing member B on the side and inserting the short shaft rod 2 into the through hole 5, the pawl 6 engages with the rack teeth 3 and the short shaft rod becomes a stop for removal, completing the installation of the button. This has the effect that the button body A and the button fastening member B maintain a strong bond.

Reference numeral 12 denotes an edge provided with buttonholes 13, which overlaps one edge 10 of the garment.

Also, by pulling the knob 8, the claw 6 in the through hole 5 retreats against the elasticity, and is disengaged from the rack claw 3, allowing the button body to be removed from the garment. Since it is easy to attach to clothing, by carrying a spare button, you can immediately attach the spare button in case the button is torn off. effective.
