Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
145 words
A protective structure for a joint of a body limb comprising first and second spaced band members adapted to be circumferentially secured to a limb in generally parallel relation at opposite ends of a body joint, a pair of elongated members secured to said first and second spaced band members, an elongated member being located at each side of a joint when the structure is positioned upon a limb of a wearer, each elongated member being of relatively rigid, integral construction and capable of being flexed to a bowed condition with and in response to movements of a body limb of a wearer, means secured adjacent opposed ends of each elongated member for confining said elongated members in an arched condition, and guard means secured to the bowed, elongated members and extending generally normal with respect to the elongated members and forwardly of a joint.
Claim 2
Dependent Claim
