Patent ID: 8505272

Claim:
A cable protection and guide device having a number of link frame bodies connected to each other in a cable longitudinal direction between a cable movable end and a cable fixed end, comprising: each of said link frame bodies includes an interior, said cable residing in said interior of said number of number of link frame bodies; each of said link frame bodies taking a linear position in which said device is in contact with a support surface of a support and a flexional position in which said device is spaced from the support surface; each of said link frame bodies includes: a pair of laterally spaced apart link side plates; said link side plates form a flexional circumferential bend having a flexional inner circumferential side and a flexional outer circumferential side; each of said spaced apart link side plates integrally includes: a front side plate portion connected to a preceding link side plate in said cable longitudinal direction to form a flexional inner circumferential side, a rear side plate portion connected to a succeeding link side plate in said cable longitudinal direction to form a flexional outer circumferential side, and, a flexible linkage portion interposed between said front side plate portion and said rear side plate portion; a flexional outer circumferential side connecting arm bridging over said flexional outer circumferential side of said link side plates; a flexional inner circumferential side connecting arm bridging over said flexional inner circumferential side of said link side plates; and, said rear side plate portion comprises a first linear position holding surface and a second linear position holding surface, respectively, provided at rear and front sides thereof in said cable longitudinal direction, said first linear position holding surface has two faces whose attitudes are mutually different with respect to said lateral direction to form one of convex and concave shapes, said second linear position holding surface has two faces whose attitudes are mutually different with respect to said lateral direction to form the other of said convex and concave shapes, said first linear position holding surface of said rear side plate portion of one link side plate being in surface contact with said second linear position holding surface of said rear side plate portion of said succeeding link plate at each of said two faces when said device is in said linear position.
