Description

[Detailed Description of the Invention] The present invention relates to a button, and particularly to a female snap button.

[Prior art and its problems]

Snap buttons have been widely used as fasteners for clothing and the like. A snap button consists of a male snap with a round stud with a swollen tip, and a female snap (also called a socket) that elastically receives this stud. It consists of a socket body 2 which has a central hole at the bottom for fixing to the socket body and an opening at the top to receive the locking round head of the male snap, and a spring ring 3 which is freely held in the inner peripheral groove of the socket body 2.
On the other hand, the male snap has a flange 5 fixed to the fabric 4.
and a stud 7 having a bulging round head 6. These male and female snaps are attached to the mounting members 8 and 9.
are fixed to the fabrics 1 and 4, respectively. The socket body 2 of the female snap in FIG. 1 projects considerably beyond the surface of the fabric 1. FIG. 2 shows another type of conventional female snap snap, consisting of a base flange 10 and a spring socket body 11 for receiving the male snap (see FIG. 1), which is fastened to the fabric 1 by an attachment member 12. However, in this case as well, the socket body 11 largely protrudes from the surface of the fabric 1. FIG. 3 shows still another type of conventional female snap, which is composed of a base flange 13, a socket body 14 having an inner circumferential groove, and a spring ring 15 freely movably held in the inner circumferential groove. 16, it is fixed onto the fabric 1. In this example, the socket body 14
Although the height of the socket body 14 can be made lower than that of the conventional example shown in FIG.
The height of the socket body is still a considerable value.

As can be seen from these examples, the female snaps of conventional snap buttons protrude significantly from the surface of the garment, resulting in an unsightly appearance. Also, the distance from the bottom of the mounting member to the top of the socket body, that is, the thickness at the time of mounting, increases, which is undesirable.
Furthermore, if you want to selectively use female snaps from both sides of the fabric, as shown in Figure 4, it is necessary to attach female snaps like those shown in Figure 1 to the front and back of the fabric, so the total thickness can be reduced. The problem was that it became thicker and thicker.

[Purpose of invention]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a female snap button with a low height.

Another object of the present invention is to provide a female snap that is not only low in height, but also allows the male snap to be attached to and removed from both sides of fabrics such as clothing.

[Summary of the idea]

The female snap according to the present invention includes a base flange that can come into contact with the fabric to be attached or one side of the fabric, a cylindrical body that stands up from the base flange, and a cylindrical body formed on the inner peripheral surface of a bulge formed in the cylindrical body. and a spring ring held in a circumferential groove. The free end of the cylinder can be crimped to the other side of the fabric. An annular attachment member is used, and after the cylindrical body of the female snap is inserted into the hole in the fabric, the attachment member is fitted around the cylindrical body, and the free end of the cylindrical body is pushed outward by a jig. Attach by caulking it to the fabric while expanding.

According to the female snap of the present invention, the spring ring is embedded in the fabric, and its total thickness can be made very thin. Furthermore, when using a female snap with this structure, there is no functional distinction between the front and back, and if you want to selectively fix other fabrics on both sides, you can attach and detach the male snap from both sides without increasing the thickness at all. Can be done.

[Explanation of Examples]

An embodiment of the female snap of the present invention will be described with reference to FIGS. 5 to 10. In this embodiment, a female snap is used in combination with a mounting member.

FIG. 5 is a sectional view showing the installed state, and FIG.
Figure 11 shows the state before installation.

As shown in FIGS. 6 and 7, the female snap 20 has a base flange 21 that comes into contact with one side of a fabric (leather, synthetic leather, other sheet materials, cloth, etc.) 22 (see FIG. 5) and a hollow cylindrical body 23. including. The cylindrical body 23 has an intermediate portion bulged to form a bulged portion 24,
The opposite surface forms a circumferential groove on the inner surface of the cylindrical body, and the spring ring 25 is freely held in the circumferential groove. The free end 25 of the cylindrical body 23 is expanded outward and crimped to the other surface of the fabric, as will be described later.

As shown in FIGS. 8 and 9, the attachment member 26 is an annular body having an opening 28 that is slightly larger than the other part 25 of the cylindrical body 23 of the female snap 20, and also has a tapered part 27 that helps fixation to the fabric. have.

In use, the cylindrical body 23 of the female snap is inserted into a through hole provided in the fabric, or a hole which is expanded in the case of a knit product, and the base flange 21 is brought into contact with one side of the fabric (see FIG. 5). Next, the annular attachment member 26 is fitted onto the cylindrical body 23 and brought into contact with the other side of the fabric. Next, a cylindrical caulking die 29 as shown in phantom lines in FIG. 6 is hammered into the end portion 25 of the cylinder. As a result, the end portion 25 of the cylindrical body expands to form the mounting member 2 as shown in FIG.
It is caulked to the 6th side. Because of the annular attachment member 26, only the portion of the end portion 25 that protrudes from the attachment member is successfully caulked during this caulking, and deformation does not extend to the inner circumferential groove 24 that supports the spring ring 25.

As can be seen from FIG. 5, according to the present invention, the installation height (thickness) of the female snap 20 is reduced, and the spring ring 25 is located at or near the same position as the fabric. Therefore, even if the thickness of the mounting member is combined, the shape is much closer to a planar shape than the conventional one. Furthermore, there is also the functional advantage that the male snap can be engaged with and detached from the female snap from any side.

Note that the annular attachment member may be of a flat plate shape as shown at 26' in FIG. 10, but there will be a slight difference in the tightening force against the fabric.

[Modified example]

FIG. 11 shows a modification of the free end 25 of the cylindrical body 23 of the female snap. In this example, three grooves 30 are formed on the circumferential surface of the end portion 25 to facilitate caulking.

As described above, according to the present invention, the above-mentioned effects can be obtained.
