It is characterized in that when it is opened, it is locked by the triple edges of the outwardly expanding peripheral edge 5 of the middle cylinder 4, the outer edge 7 of the bottom wall 6, and the outwardly expanding curled edge 10.

(Example) The tuck button according to the present invention will be described below with reference to the example shown in FIGS. 1 to 3.

That is, the tuck button of the present invention is made up of a combination of the button body H1 and the mounting part T, as in the conventional case, but
In particular, the button body H1 extends upward from the center of the seat plate 1 to form an outer cylinder 2 and a top surface 3 continuing therefrom, and a middle cylinder 4 is provided downward from the top surface 3, and a tip of the middle cylinder 4 is formed. The outer edge 7 of the bottom wall 6 that follows the bottom wall 6 is formed in an outwardly expanding peripheral edge 5, and the outer edge 7 of the bottom wall 6 is continuously provided in an outwardly expanding shape so as to overlap with the aforementioned outwardly expanding peripheral edge 5.

In this state, as shown in FIG. 3, a through hole 9 (FIG. 1) is drilled in the center from above the bottom wall 6 using a punching tool 8, and a curled edge 10 is connected to the outer edge 7. The tip of the middle tube 4 is formed into a triple edge of a peripheral edge 5, an outer edge 7, and a rolled edge 10, and the outer edge 7 and rolled edge 10 are formed into a triple edge.
A constricted portion 7A is provided in which the connecting portion of
It has a structure in which the peripheral edge 13 and the edge are curved.

In addition, the mounting portion T has a hollow leg 15 protruding from the center of the seat plate 14, and the hollow leg 15 has a large diameter portion 16, a circumferential portion 17, and a tip portion of the hollow leg 15 in order from the root portion. The seat plate 1 is formed in a small diameter portion 18 that is
4 has a top plate 19 attached thereto.

The button body H1 and the mounting part T configured in this way are
As shown in FIGS. 1 and 2, when the hollow leg 15 of the attachment portion T is passed through the fabric through the through hole 9 of the inner cylinder 4 of the button body H1 and strong pressure is applied in the axial direction of the hollow leg 15, the hollow leg 15 The small diameter portion 18 of the leg 15 enters the curled edge 10 of the through hole 9, the large diameter portion 16 of the hollow leg 15 enters the inner wall 4A of the middle cylinder 4, and the small diameter portion 18 protruding from the curled edge 10 enters the middle. When in contact with the plate 11, the circumferential step 17 of the hollow leg 15 engages with the inner constriction 7A of the connecting portion between the outer edge 7 and the curled edge 10 and is crushed, and the tip of the small diameter portion 18 The part transforms into an octopus-like process 1A, and the octopus-like process 1
The neck 1B of A expands the curled edge 10 outward and is locked by the triple edge of the outer edge 5 of the middle tube 4, the outer edge 7 of the bottom wall 6, and the rolled edge 10 that expands outward. This will lead to

In addition, since the thickness of the fabric 20 is thin, if the hollow leg 15 of the attachment part T is a little too long, the head of the octopus-shaped protrusion 1A formed by contacting the middle plate 11 will be formed in a double shape. Sometimes.

(Operations and Effects of the Invention) According to the tuck button of the present invention as described above, unlike conventional tuck buttons, the tip of the middle tube 4 is formed into a triple edge of the peripheral edge 5, the outer edge 7, and the rolled edge 10. At the same time, since a constricted portion 7A is provided in which the connecting portion between the outer edge 7 and the rolled edge 10 projects inward, the circumferential step portion 17 of the hollow leg 15 engages with the constricted portion 7A.
Furthermore, the neck 1B of the octopus-like projection 1A is locked at the triple edge of the peripheral edge 5, outer edge 7, and curled edge 10 of the tip of the middle tube 4, resulting in a two-stage locking, making the hollow even more solid. The legs 15 are attached to the middle tube 4 and will not loosen or come off the attachment part T.

In other words, the button body H1 and the mounting portion T are tightly connected to each other to prevent loosening, coming off, or rotation, thereby providing a tuck button that can be used with peace of mind.
