Cable protection and guide device

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 fixed end and a cable movable end, comprising:

• said cable fixed end affixed to a fixed support;
• said cable movable end affixed to a movable support;
• each of said link frame bodies includes an interior, said cable residing in said interior of said number of link frame bodies, said cable accommodated in said interior of said link frame bodies from said cable fixed end to said cable movable end;
• each of said link frame bodies includes a pair of laterally spaced apart right and left link side plates;
• each of said pair of said laterally spaced apart right and left link side plates are articulately connected to each other in a longitudinal direction enabling said side plates of said link frame bodies to form a flexional circumferential bend having a flexional inner circumferential side and a flexional outer circumferential side;
• each of said laterally spaced apart right and left link side plates includes a flexional inner circumferential side residing during bending on said flexional inner circumferential side of said bend;
• each of said laterally spaced apart right and left side plates includes a flexional outer circumferential side residing during bending on said flexional outer circumferential side of said bend;
• each of said laterally spaced apart right and left link side plates integrally includes a front side plate portion connected to an adjacent link side plate in said cable longitudinal direction to form said flexional inner circumferential side, a rear side plate portion connected to another link side plate in said cable longitudinal direction to form said flexional outer circumferential side, and, a flexible linkage portion interposed between said front side plate portion and said rear side plate portion;
• a first portion of said link frame bodies taking a linear position in which said first portion of said link frame bodies is in contact with a support surface of a support and a second portion of said link frame bodies taking a flexional position during bending in which said second portion of said link frame bodies is spaced from said support surface;
• said rear side plate portion of each of said laterally spaced apart right and left link side plates includes a first flexional outer circumferential end surface which is in an arc shape on said flexional outer circumferential side;
• during bending, a gap is formed between said first flexional outer circumferential end surface of said link side plate and said support surface of said support;
• a flexional outer circumferential side connecting arm bridging over said flexional outer circumferential side of said right and left link side plates;
• and,
• a flexional inner circumferential side connecting arm bridging over said flexional inner circumferential side of said right and left link side plates.
