Abstract
A button having a button body including a central portion defining a button base having an uninterrupted outer wall and an inner wall with interspaces within said button base between said outer and inner walls, and an attaching means comprising a supporting plate including a plurality of pins projecting from one face of the supporting plate and having pointed heads adapted to be punched through a sheet material to which the button is to be attached, and then inserted into openings into the interspaces between said outer and inner walls, the openings being constricted to require temporary deformation of the materials of the structure as the heads of the pins are inserted into the openings.
Claims20
A button which is quickly attachable to sheet material such as textile cloth comprising
- a button body including a central portion defining a button base and having an uninterrupted outer wall and an integral inner wall with interspaces generally arranged around the axis of the button body and between said outer and inner walls,
- said button body including openings generally aligned parallel to the button axis from the bottom of the button body into said interspaces,
- an attaching means comprising a supporting plate including at least two substantially mutually parallel pins projecting from one face of said supporting plate and arranged around a center axis thereof,
- said pins having pointed heads adapted to be punched through said sheet material from the side of said material opposite to the side to which the button is to be attached,
- said pins being adapted to be then inserted into said openings into said interspaces between said outer and inner walls of said button body for attachment of said button body to said sheet material,
- the radially inwardly facing side of the head of each of said pins adjacent to said inner wall in the assembled position being substantially smooth,
- said heads of said pins each having a radial dimension as measured along a radius from the center axis of said supporting plate which is greater than the remainder of the body of the associated pin,
- the radial dimension of each of said interspaces between said inner and outer walls of said button body being at least as great as said radial dimension of said pin heads,
- said outer wall of said button body including at least one radially inwardly extending flange at said openings into said interspaces to restrict said openings to a radial dimension substantially less than said radial dimension of each of said pin heads so that the materials of the structure must be temporarily deformed to permit insertion of said pins into said axial openings.
