Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
122 words
A polymeric snap-on attachment for a hollow rivet chain, comprising: first and second side members adapted to lie adjacent to the sidebars of the chain, at least one of said side members including an integral extension, and at least one of said side members including an integral pin-like projection adapted to fit through one of the hollow rivets in said chain; the other of said side members having a receptacle which receives said pin-like projection with a snap fit so as to fix said first and second side members to each other and to the chain, and an inwardly directed leg located on the lower portion of each side member and being adapted to be attached to each other underneath the chain.
Claim 2
Dependent Claim
122 words
A polymeric snap-on attachment for a hollow rivet chain, comprising: first and second side members adapted to lie adjacent to the sidebars of the chain, at least one of said side members including an integral extension, and at least one of said side members including an integral pin-like projection adapted to fit through one of the hollow rivets in said chain; the other of said side members having a receptacle which receives said pin-like projection with a snap fit so as to fix said first and second side members to each other and to the chain, and an inwardly directed leg located on the lower portion of each side member and being adapted to be attached to each other underneath the chain.
Claim 3
Dependent Claim
54 words
