Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to buttons, and more particularly to buttons that can be used in place of conventional tactile buttons.

A tack button is a type of button that has a buttonhole formed on one side of the garment and a button fixed on the other side, allowing the button to be inserted into and removed from the buttonhole. A tack pin insertion hole is provided in the button, and the tack pin is driven into the tack pin insertion hole through the clothing material to lock the tip of the tack pin into the button.

FIGS. 1 and 2 show two typical examples of conventional tact buttons. In the example shown in FIG. 1, a metal plate 4 is inserted into a metal button 3 in which a decorative plate 1 and a cylindrical bag 2 having an inner curved portion forming a tuck pin insertion hole are joined together at their outer peripheries. Base flange 5
A metal tack pin 6 having a tack pin 6 is inserted into the tack pin insertion hole of the button through the clothing material 7, and is struck against the metal plate 4 to curve or bulge the tip of the tack pin 6 and fix it. In the example shown in FIG. 2, a locking portion is formed at the inner end of a tack pin insertion hole of a cylindrical plastic bag 9 having a decorative plate 8, and a tack pin 12 having a base flange 11 is driven into the locking portion through the garment fabric 10. The tip hook portion of the tack pin 12 is engaged with the locking portion of the tack pin insertion hole of the button.

In these conventional examples, the installation is difficult due to the curvature or bulge of the tip of the tack pin (example in Figure 1), or due to forced insertion of the tip of the tack pin which is much larger than the insertion hole (example in Figure 2). Since a large amount of force is required, special installation machines and tools are required. Moreover, it is very troublesome to remove the button once it is attached, and the removed tack cannot be reused because it undergoes plastic deformation.

Therefore, it is an object of the present invention to provide a button similar to a tack button without using a tack pin, and which can be replaced with another button as needed.

The present invention will be described in detail below with reference to the drawings.
Referring to FIGS. 3 and 4, the button 12 of this embodiment
is made of a strong plastic molded body, and includes a decorative plate 13 (covered with a metal plate or whose surface is designed or colored as necessary) and a columnar part 14. The lower side of the columnar part 14 is divided into four by intersecting slots 15 as shown in FIG.
Two elastic legs 16, 17, 18, and 19 are formed. Two substantially annular flanges 20 and 21 are formed around the legs 16 to 19 at predetermined intervals. The spacing between these flanges 20, 21 is determined in relation to the thickness of the clothing material, and more precisely, it is determined by the thickness of the eyelet fixed to the clothing material.

To attach the button constructed as described above to a predetermined location on the garment fabric 23, first insert the eyelet 22 into the hole in the garment fabric 23 as shown in FIG.
Caulk so that the dimension t ₂ is slightly smaller than the dimension t ₁ of the internal rule of 0.21. There is no need to consider the dimension of t ₂ too strictly. The legs 16-19 of the button 12 are then pushed into the holes of the eyelets 22 with inward pressure using a suitable tool or possibly by hand. As a result, the legs 16 to 19 elastically fit into the eyelets 22 and are restored and fixed to the clothing fabric. Once a button is fixed, it cannot be removed by normal button-unhooking operations. On the other hand, if you want to replace the button 12 as necessary, press the flange 20 inward using a suitable tool (pliers, etc.) to replace the leg 12.
It can be easily removed by pulling the button while bending sections 6 to 19.

FIG. 6 shows a leg of a button according to another embodiment of the present invention. The difference between this example and the above example is that
A groove with a radius R is formed between the flanges 20 and 21. Correspondingly, the inner edge of the eyelet 22 is also attached to the clothing material so that it has a radius slightly smaller than the radius R (the right side is omitted in FIG. 6). This allows the button 12 to swing to a certain extent.

As described above, according to the present invention, the button is easy to attach and will not come off during normal use. In addition, since the buttons and eyelets can be easily replaced without damaging them, even end users can use them conveniently.
