Abstract
Abstract A button structure is disclosed, which can be applied to, and removed from, any fabric or garment without sewing or unstitching operations, the structure comprising a pointed stem adapted to penetrate a fabric and having a retaining base portion, a capsule which is composed by a button shield and a recessed boss integral therewith, the recess of the boss being capable of holding the pointed end of the stem by elastic reaction. The button structure successfully withstands virtually any pulling force tending to remove the button from the fabric. The subject structure can be easily dismembered whenever so desired, by merely pressing the component parts, i.e. the capsule and the stem together.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
260 words
A separable button assembly comprising: a solid button having a single through hole therethrough convergent toward the rear face thereof; a fastening member having an enlarged base and a solid stem terminating in an enlarged pointed end having a rearward portion tapering toward said base, said stem being adapted to pierce fabric and extend into said button hole with said base overlying the rear face of the fabric; a retaining member having an enlarged crown adapted to overlie the front face of said button and a central socketed portion adapted to extend through said button hole and to receive said pointed end, said socketed portion being resilient and having an interior restriction provided with annular surfaces on the opposite sides thereof which are convergent toward each other, the minimum diameter of said restriction, when relaxed, being less than the maximum diameter of said pointed end, and said socketed portion having an exterior tapering portion adjacent said crown generally complementary to said button hole, whereby after said stem has pierced fabric and extended through said button hole, said socketed portion can be snapped over said pointed end by resilient expansion of said restriction and thereafter said button hole engaged with said complementary tapering portion on said stem to prevent expansion of said restriction and lock said stem end in said socketed portion, and said button hole can be disengaged from said complementary tapering portion on said stem to permit snapping release of said end from said socketed portion; and resilient snapping means releasably retaining said socketed portion in said button hole.
Claim 2
Dependent Claim
260 words
A separable button assembly comprising: a solid button having a single through hole therethrough convergent toward the rear face thereof; a fastening member having an enlarged base and a solid stem terminating in an enlarged pointed end having a rearward portion tapering toward said base, said stem being adapted to pierce fabric and extend into said button hole with said base overlying the rear face of the fabric; a retaining member having an enlarged crown adapted to overlie the front face of said button and a central socketed portion adapted to extend through said button hole and to receive said pointed end, said socketed portion being resilient and having an interior restriction provided with annular surfaces on the opposite sides thereof which are convergent toward each other, the minimum diameter of said restriction, when relaxed, being less than the maximum diameter of said pointed end, and said socketed portion having an exterior tapering portion adjacent said crown generally complementary to said button hole, whereby after said stem has pierced fabric and extended through said button hole, said socketed portion can be snapped over said pointed end by resilient expansion of said restriction and thereafter said button hole engaged with said complementary tapering portion on said stem to prevent expansion of said restriction and lock said stem end in said socketed portion, and said button hole can be disengaged from said complementary tapering portion on said stem to permit snapping release of said end from said socketed portion; and resilient snapping means releasably retaining said socketed portion in said button hole.
Claim 3
Dependent Claim
68 words
The structure defined in claim 1 in which the socketed portion is provided with an exterior enlargement adjacent the smaller end of the exterior tapering portion thereof, said enlargement being adapted to be resiliently constricted to pass through the button hole and to resiliently expand to underlie the rear face of the button to yieldingly retain said button hole in engagement with the complementary portion on said stem.
Claim 4
Dependent Claim
32 words
The structure defined in claim 2 in which the socketed portion is extended beyond the exterior enlargement to substantially engage with the front face of the fabric when the parts are assembled.
Claim 5
Dependent Claim
53 words
The structure defined in claim 1 in which the snapping means includes an annular interiorly undercut rim on the outer face of the button and a circular edge on the crown adapted to snappingly engage under said rim to releasably retain the button hole in engagement with the complementary portion on the stem.
