Abstract
Abstract A releasable self-retaining means for fastener assemblies employing a U-shaped spring hook for attaching a webbing material to a slotted or perforated frame. The self-retaining means consists of a three-point frictional contact produced between the hook legs and the frame in response to the spring resiliency and while the hook slides to and from latched position. Cam means at the free end of one of the hook legs initially guides the hook into the three-point contact as the latter moves toward latched position, and a second cam means at the opposite end of the leg initially guides the hook into the three-point contact when the hook moves reversely from latched position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
114 words
A fastener assembly for webbing materials comprising a Ushaped spring hook, means securing one leg of said hook to said material, an elongated plate member having a transverse perforation therethrough, means responsive to the spring action of said hook upon insertion of the other hook leg into said perforation for yieldingly pressing the inner and outer surfaces of the latter leg into frictional sliding engagement with oppositely disposed edges of said perforation, respectively, and means operable subsequent to the operation of said second means for relieving said frictional engagement to releasably latch said hook in anchored position, whereby said frictional engagement will yieldingly resist movement of the hook to and from its anchored position.
Claim 2
Dependent Claim
114 words
A fastener assembly for webbing materials comprising a Ushaped spring hook, means securing one leg of said hook to said material, an elongated plate member having a transverse perforation therethrough, means responsive to the spring action of said hook upon insertion of the other hook leg into said perforation for yieldingly pressing the inner and outer surfaces of the latter leg into frictional sliding engagement with oppositely disposed edges of said perforation, respectively, and means operable subsequent to the operation of said second means for relieving said frictional engagement to releasably latch said hook in anchored position, whereby said frictional engagement will yieldingly resist movement of the hook to and from its anchored position.
Claim 3
Dependent Claim
36 words
A fastener assembly as defined in claim 1 wherein said second means further includes interengaging means between said plate and said first leg for diverging the free end of the latter relative to the inserted leg.
Claim 4
Dependent Claim
35 words
A fastener assembly as defined in claim 2 wherein said third means includes a cam surface substantially at the junction of said legs and forming a continuation of said outer frictionally engaged outer leg surface.
Claim 5
Dependent Claim
33 words
A fastener assembly as defined in claim 3 wherein the leading insertion end of said other leg is provided with a flared extension normally diverging relative to the axis of said first leg.
Claim 6
Dependent Claim
35 words
A fastener assembly as defined in claim 1 wherein said third means includes a cam surface substantially at the junction of said legs and forming a continuation of said outer frictionally engaged outer leg surface.
Claim 7
Dependent Claim
33 words
A fastener assembly as defined in claim 5 wherein the leading insertion end of said other leg is provided with a flared extension normally diverging relative to the axis of said first leg.
Claim 8
Dependent Claim
38 words
A fastener assembly as defined in claim 1 wherein said other leg is substantially S-shaped and consists of a straight shank portion having reversely bent end portions, one of said end portions forming a junction between said legs.
Claim 9
Dependent Claim
37 words
A fastener assembly As defined in claim 7 wherein said third means includes a cam surface on said last-named leg end portion, said cam surface forming a continuation of the frictionally engaged outer surface of the latter.
