Abstract

A button device including a standard button having the usual holes, a pair of pin members snapingly received in two of the holes in the button and projecting downwardly from the underside of the button, a housing adapted to be positioned against the underside of the associated fabric and including a pair of holes in its upper surface for receipt of the pins on the button, a sheet of spring steel positioned within the housing and including a pair of apertures adapted to receive the pins with an interference fit and including flap portions which flex downwardly in response to passage of the pins and engage in notches in the pins to secure the button to the housing, and a release pin passing through an aperture in the lower surface of the housing and engaging an aperture in the spring sheet to flex the flap portions of the spring sheet further downwardly to a disengaged position in which the pins of the button are free to be withdrawn from the housing to allow the button device to be separated from the associated fabric.

Dependent claims

A button device adapted to be releasably secured to a first fabric section for coaction with a buttonhole in a second fabric section to releasably secure the fabric sections together, said device comprising:

(A) a button member having
(1) a generally disc shaped main body portion adapted to be positioned against the upper surface of the first fabric section and configured to be put through the buttonhole in the second fabric section, and
(2) a pin portion extending downwardly from the underside of said main body portion for downward passage through the first fabric section;
and
(B) an attachment assembly including
(1) a housing having a generally planar upper surface adapted to be positioned against the under surface of the first fabric section, a blind bore extending downwardly in said housing and opening in an attachment aperture sized to pass said pin portion for downward movement into said blind bore, a lower surface spaced downwardly from said upper surface, and a blind bore extending upwardly in said housing and opening in said lower surface in a release aperture,
(2) catch means, positioned within said housing in intersecting relation to said blind bores, operative in response to movement of said pin portion downwardly through the first fabric section and into said downwardly extending blind bore to releasably secure said pin portion to said housing, and
(3) an elongated release member extending upwardly into said upwardly extending blind bore for engagement at its upper end with said catch means and operative in response to actuation thereof to release said pin portion from said catch means to allow the withdrawal of said pin portion upwardly through the first fabric section and release of the button device from the first fabric section.
