Abstract
Abstract A system for providing metallic armor protection for flexible body covers, such as gloves or finger cots, to prevent accidental cutting or piercing of the wearer by sharp instruments, such as scalpels or hypodermic needles. The flexible elastomer material that is used for the protective cover is provided with small closely spaced projections, on which overlapping circular metal discs are impaled. The overlapping metallic discs are free to move over each other to allow total flexibility; and the small round ended elastomer projections provide excellent friction to grasp smooth metallic objects, and transmit the sense of touch.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
121 words
An armored cover comprising: a flat, flexible elastomer base having a plurality of identical, cylindrically shaped, spaced apart projections extending outwardly from at least one face of the base and arranged in a plurality of parallel rows; a plurality of identical discs made of metal and respectively disposed on said projections, the inside diameter of a disc being less than the outside diameter of its projection and conically shaped to develop forces to hold the disc on the projection; and the distance between any pair of adjacent projections in any row is the same and the outside diameter of each disc being chosen so that the disc on any one projection and the disc on any adjacent projection overlap each other.
Claim 2
Dependent Claim
121 words
