Abstract
Abstract A snap fastener combination of the type comprising four molded plastic component parts wherein the socket component has a cupshaped flange joined to the central portion thereof adjacent the entrance to the stud receiving cavity of the socket component. The flange extends radially outwardly and upwardly from its junction with said central portion and is of reduced thickness adjacent said junction to provide a hinging web which renders the socket both radially and axially distensible responsive to insertion of the stud component into the socket cavity.

Claim 3
Dependent Claim
258 words
A socket component for a separable snap fastener comprising a body of firm but yielding tenacious and resiliently distensible polymeric material in the form of a solid of revolution and including a central portion defining a stud receiving cavity, said cavity having a peripheral wall circumscribing the central axis of said socket and the roof of said cavity being disposed adjacent the upper end of said central portion of said socket, and an integral, cup-shaped peripheral flange joined to said central portion adjacent the lower end thereof and relatively proximate the entrance to said cavity and extending radially outwardly and upwardly at an acute angle relative to the central axis of the socket from its junction with said central portion and terminating in an upper planar surface which engages a support element to which the socket is attached at points substantially radially spaced from said central portion to stabilize said socket relative to the support element, said upper planar surface being located in a plane lying substantially transverse the central axis of said socket and intersecting said axis at an imaginary point disposed substantially upwardly of the entrance to said cavity, the material thickness of said flange adjacent its junction with said central portion being substantially less than the material thickness of said central portion for substantially the full depth of said cavity, said flange defining, adjacent said junction, a resilient hinging web about which said central portion Of said socket distends and resiles responsive to the insertion of a cooperating snap fastener stud component into said cavity.
Claim 4
Dependent Claim
258 words
A socket component for a separable snap fastener comprising a body of firm but yielding tenacious and resiliently distensible polymeric material in the form of a solid of revolution and including a central portion defining a stud receiving cavity, said cavity having a peripheral wall circumscribing the central axis of said socket and the roof of said cavity being disposed adjacent the upper end of said central portion of said socket, and an integral, cup-shaped peripheral flange joined to said central portion adjacent the lower end thereof and relatively proximate the entrance to said cavity and extending radially outwardly and upwardly at an acute angle relative to the central axis of the socket from its junction with said central portion and terminating in an upper planar surface which engages a support element to which the socket is attached at points substantially radially spaced from said central portion to stabilize said socket relative to the support element, said upper planar surface being located in a plane lying substantially transverse the central axis of said socket and intersecting said axis at an imaginary point disposed substantially upwardly of the entrance to said cavity, the material thickness of said flange adjacent its junction with said central portion being substantially less than the material thickness of said central portion for substantially the full depth of said cavity, said flange defining, adjacent said junction, a resilient hinging web about which said central portion Of said socket distends and resiles responsive to the insertion of a cooperating snap fastener stud component into said cavity.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
76 words
The combination of the socket defined in claim 2 secured to a support element at one surface of the element by a rivet having a flange overlying and engaging the remote surface of the support element, a shank joined to said flange and extending through said support element and said axially disposed opening in the upper end of said central portion, and a head portion lying within said cavity and gripping the roof of said cavity.
Claim 7
Dependent Claim
96 words
The combination as set forth in claim 3 wherein said flange of said rivet has an inverted cup shape and includes a downwardly extending peripheral rim terminating in a lower planar surface, and the support element is clamped between the undersurface of said rivet flange adjacent said shank and the upper end of said central portion of said socket and between the lower planar surface of said rim of said rivet flange and the upper planar surface of said socket flange, which latter surfaces are disposed in opposed relationship on opposite sides of the support element.
