Button Fastener and Button Structure

Abstract

The button fastener comprises a fastener body and a cover member which is attached to the fastener body. The fastener body includes a disk-like base and a hollow, cylindrical post extending upward from a center area of the base concentrically. The post has a top opening at its upper end and a bottom opening in a center area of the base. The cover member covers the lower surface of the base including the bottom opening. The base includes a base bottom adjacent to the post and a base flange rising upward relative to the base bottom radially outward from the base bottom. The cover member includes a curved outer periphery curving from the lower surface side of the base and then rising upward beyond the base flange of the base.

Description

BACKGROUND OF THE INVENTION[0001]This invention relates to a button fastener and a button structure, and more specifically, to a button fastener to fasten a button such as a decorative button, a snap button to a fabric, and a button structure composed of a button and a button fastener.[0002]As a combination of a button and a button fastener to fasten the button to a fabric, a type has been known where a button is fastened to a fabric by deforming and fixing a post of a button fastener within a post-receiving space or an inside space of a projection of the button, after the post has pierced the fabric to be received in the space, as shown in Japanese Examined Utility Model Application Publication No. S60-8724, Japanese Published Patent Application No. 2005-204911. As examples of such a button, there are a decorative button, which is fastened to e.g. corners of a pocket of jeans, and a male snap of a snap button, which is mounted to e.g. parts of clothes to be put together. In a state...

AI Technical Summary

Benefits of technology

The present invention provides a button fastener for fastening a button to a fabric. The fastener includes a fastener body with a post and a cover member with a curved outer periphery. The cover member covers the lower surface of the fastener body and the fabric is held between the flange of the button and the curved outer periphery of the cover member. The button fastener is designed to securely fasten the button to a thinner fabric. The invention also provides a button structure composed of a button and the button fastener.

Problems solved by technology

However, with conventional buttons and button fasteners, when a fabric is thin, it would be unable to firmly hold the fabric between the flange of a button and the base of a button fastener, and there would be a case that a button cannot be surely fastened to a fabric.

With common button fasteners, the piece would go into the post-receiving space of the button, which could hamper a deformation of the post, have an adverse effect on the connection between the button and the button fastener, and necessitate an additional work to remove fabric pieces after a button mounting work.
