Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
112 words
A pin having a spring type, press-fit section, said pin comprising an elongated piece of material, said pin having two end portions and at least one press-fit section intermediate its ends, said press-fit section having two opposed basically flat, planar sides which terminate in smooth curved ramps, said ramps forming a juncture portion with said end portions, the remaining two opposed sides of said press-fit section each containing one elongated, radiused central depression, each depression having a one-quarter spherical depression at each of its ends, said pressfit section having a basically I-beam cross-section, said pressfit section of said pin adapted to be inserted into an aperture and to be securely retained therein.
Claim 2
Dependent Claim
