Abstract
Abstract This invention relates to an edge protector, moulding or beading made of deformable material for bordering the edges of structures of constant or variable thickness, which protector, moulding or beading has a carrier of semi rigid, resiliently deformable material of U-shaped cross section which is embraced by a covering material of rubber or plastics material, that portion of the covering material which is arranged on the inner faces of the arms of the carrier being formed of a softer material that the remainder of the covering material so that once the protector, moulding or beading has been applied to the edge, the softer material, which is in contact with the edge, will provide a very strong grip.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
141 words
An edge protective beading comprising in cross section: a. a substantially rigid, and generally U-shaped carrier; b. the legs of said carrier diverging outward and then converging inward to terminate in resilient free ends; c. a covering material wrapped loosely around the outer surface of said carrier and extending around said free ends and into the interior of said carrier; d. the portion of said covering material extending to said interior of said carrier forming a pair of grippers for holding said covering material on said carrier and for holding said beading on said edge; e. said grippers being wedge-shaped to increase in thickness with distance from said free ends for fitting inside said convergent free ends to engage said edge; f. confronting portions of said grippers being formed of a material substantially softer than the rest of said covering material.
Claim 2
Dependent Claim
141 words
An edge protective beading comprising in cross section: a. a substantially rigid, and generally U-shaped carrier; b. the legs of said carrier diverging outward and then converging inward to terminate in resilient free ends; c. a covering material wrapped loosely around the outer surface of said carrier and extending around said free ends and into the interior of said carrier; d. the portion of said covering material extending to said interior of said carrier forming a pair of grippers for holding said covering material on said carrier and for holding said beading on said edge; e. said grippers being wedge-shaped to increase in thickness with distance from said free ends for fitting inside said convergent free ends to engage said edge; f. confronting portions of said grippers being formed of a material substantially softer than the rest of said covering material.
Claim 3
Dependent Claim
63 words
The beading of claim 1 wherein the innermost ends of each of said grippers are bifurcated to form two fingers, one of the fingers of each of said pairs of said fingers engaging the inside of said inturned free ends, and the other of the fingers of each of said pairs of said fingers being mutually confronting and formed of said softer material.
