In addition, the protrusions (15) cut into the cloth (1) and compress the cloth (1) intensively, and thereby the cloth (1) enter the recesses (14) thus relaxing the compression. Consequently, the cloth (1) is pulled between the protrusions (15) and the recesses (14). The cloth (1) is cut easily by the post (12) because the cloth (1) is compressed and pulled strongly and weakly in the circumferential direction by means of the recesses (14) and the protrusions (15).

Description

Button mounting member and button

The present invention relates to a button mounting member and a button, and more specifically, a button mounting member of a type in which a cylindrical post portion is plastically deformed to attach a button to a cloth, and a male snap attached to the cloth by such a button mounting member. It relates to buttons such as buttons and decorative buttons.

The male snap button of the snap button often used for clothes joints, etc. has a projection part to be attached to and detached from the projection receiving part of the female snap button, and is made by drawing a metal plate as one type of male snap button, It is known that the protruding end side of the protruding portion is closed and the proximal end side is opened. When this type of male snap button is attached to the fabric, a button attachment member having a cylindrical post portion is used to insert the post portion penetrating the fabric into the inner space of the projection portion of the male snap button. It is deformed and locked. Such a combination of a male snap button and a button mounting member is disclosed in, for example, US Pat. No. 3,351,987. In addition, for example, a decorative button having a hemispherical protrusion attached to a corner of a jeans pocket similarly accepts a post portion of a button attachment member penetrating the fabric in the inner space of the protrusion, and deforms and locks it. By doing so, it is fixed to the dough.

When attaching a button having a protrusion with a protruding end closed as described above to a cloth, when the post part of the button mounting member is passed through the cloth, the post part to cut the cloth is subjected to piercing force (cutting from the cloth). However, depending on the type and thickness of the fabric, attachment failure may occur due to the piercing force being too great and the post portion being deformed when the fabric is cut. For this reason, conventionally, the types and thicknesses of the fabrics to which the button mounting member can be applied are limited, and the post mounting portion of the button mounting member is secured with a certain thickness or more, but in this case, the cost increases. It becomes.
