Abstract
Abstract A length of bar stock is flattened and reformed to produce a section having spring characteristics whereby the bar is capable of resiliently mating with a nonresilient article. Alternatively, a length of flat stock is stamped or etched to produce resilient members, the flat stock being rolled or left flat depending on a particular use.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
54 words
A resilient connector pin provided by a pair of spaced aligned members of uniform solid cross section and a plurality of transversely spaced resilient walls of arcuate shape integrally connected with the opposed ends of the solid members, the outer arcuate surfaces of the resilient walls extending beyond the peripheries of the solid members.
Claim 2
Dependent Claim
54 words
A resilient connector pin provided by a pair of spaced aligned members of uniform solid cross section and a plurality of transversely spaced resilient walls of arcuate shape integrally connected with the opposed ends of the solid members, the outer arcuate surfaces of the resilient walls extending beyond the peripheries of the solid members.
Claim 3
Dependent Claim
31 words
A resilient connector pin according to claim 1 in which the walls are bowed outwardly from the axis along which the members are aligned in order to provide the arcuate shape.
Claim 4
Dependent Claim
32 words
A resilient connector pin according to claim 2 in which the resilient walls are of flat material having planar surfaces which lie parallel to the plane of the arc which they define.
Claim 5
Dependent Claim
42 words
A resilient connector pin according to claim 1 in which one pair of edges of the walls is connected by a web portion, to thereby provide the connection between the opposed ends of the solid members with a substantially U-shaped cross section.
