Abstract
Abstract For detachably fastening inner and outer overlying plate members using a quarter-turn fastener, a square hole is punched in the inner panel and a snap-in receptacle assembly is inserted into the hole from the outer side of the panel and snapped into place. The receptacle assembly housing has six sides and is formed out of two components. The one component is a three-sided housing member having flange portions for bearing against the outer surface of the inner panel. The other component is a three-sided retainer member having spring legs which snap out behind the inner panel to lock the receptacle assembly in place. A compression spring inside the six-sided prism or housing has one end which bears against the front face of the retainer member and the other end bears against the fastener pressing it against rear face of the housing member and maintaining the housing and retainer members at spaced separation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
159 words
Fastening means for quickly detachably fastening together a pair of mutually overlying plate members, said fastening means including: A. a stud; B. a receptacle assembly, said receptacle assembly comprising: a. a housing member having two parallel side segments connected by a rearward segment, the free end of each of said side segment having an outwardly bent flange portion; b. a retainer member having two parallel side segments connected by a forward segment, said side segments having projecting therefrom outwardly extending spring elements; said housing and retainer members being placed in such relative assembled positions as to form a six-sided hollow rectangular prism; c. stud-engaging means within said prism; d. a spring member within said prism having its forward end bearing against said forward segment of said retainer member and its rearward end applying thrust against said rearward segment of said housing member for urging said forward and rearward segments of said retainer and housing members away from each other.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
35 words
Fastening means according to claim 1 wherein said stud engaging means comprises a socket receptacle disposed in said prism between said rearward segment of said housing member and the rearward end of said spring member.
Claim 4
Dependent Claim
35 words
Fastening means according to claim 2 wherein said forward segment of said retainer member and said rearward segment of said housing member are each provided with a centrally located aperture for passage of said stud.
Claim 5
Dependent Claim
40 words
Fastening means according to claim 2 wherein said housing member is formed from flat material bent into a U-shape such that its rearward segment is an intermediate segment between two parallel side segments and connected thereto by two right-angle bends.
Claim 6
Dependent Claim
40 words
Fastening means according to claim 2 wherein said retainer member is formed from flat material bent into a U-shape such that its forward segment is an intermediate segment between two parallel side segments and connected thereto by two right-angle bends.
Claim 7
Dependent Claim
66 words
Fastening means according to claim 2 wherein said outwardly extending spring elements which project from the side segments of said retainer member are formed by sliting portions of said side segments and bending said slit portions outwardly, said spring elements being adapted to pass through a hole cut in one of said plate members and to snap out behind the rearward surface of said plate member.
Claim 8
Dependent Claim
54 words
Fastening means according to claim 2 wherein: a. said socket receptacle is generally circular in shape and is provided with laterally-extending ears, and b. said side segments of said housing member are provided with slots for receiving said ears of said socket receptacle for preventing rotation of said receptacle when said stud is turned.
Claim 9
Dependent Claim
33 words
Fastening means according to claim 7 wherein said forward segment of said retainer member is provided with retaining ears which are received with the slots of said side segments of said housing member.
