Patent ID: 7637092

Claim:
A cable protection and guide device, comprising: coupling portions each having an interior portion and an exterior portion; each of said coupling portions include a snap-fit mechanism in said interior portion thereof; a plurality of polyacetal resin stopper links, each of said stopper links inter-fitted with a respective snap-fit mechanism in said interior portion of one of said coupling portions; connecting link modules each of which includes a number of pairs of spaced right and left side plate portions articulately connected to each other by said coupling portions and said stopper links, said coupling portions reside between said side plate portions and are integrally molded with said side plate portions, said coupling portions and said side plate portions being made of a polyamide fatigue resistant resin; said connecting link modules extend from a mounting fixed end to a mounting movable end enabling said connecting link modules formed by said side plates, said coupling portions and said stopper links to form a flexional circumferential bend having a flexional inner circumferential side and a flexional outer circumferential side; each of said side plate portions, said coupling portions and said stopper links includes a flexional inner circumferential side residing during bending on said flexional inner circumferential side of said bend; each of said side plate portions, said coupling portions and said stopper links includes an outer circumferential side residing during bending on said outer flexional circumferential side of said bend; first connecting arms are respectively bridged over said bending inner circumferential sides of said stopper links at predetermined intervals and second connecting arms are respectively bridged over bending outer circumferential sides of said stopper links at predetermined intervals; a cable accommodated and guided in a cable accommodating space, said cable accommodating space being surrounded by said side plate portions, said coupling portions, said stopper links and said first and second connecting arms from said mounting fixed end toward said mounting movable end; said cable protection and guide device assumes a linear position and a bending position; and, said stopper links hold and limit said linear position and said bending position by engagement with said side plate portions of said connecting link modules.
