Patent ID: 7591128

Claim:
A cable protection and guide device comprising: a plurality of pairs of right and left spaced side plates; each of said side plates include a connecting pin and connecting pin hole; each of said side plates are articulately connected to adjacent side plates in a longitudinal direction, said connecting pins of said plates interfit with said connecting pin holes; said articulate connection of said plates to each other in a longitudinal direction enable a portion of said side plates to form a flexional circumferential bend having a flexional inner circumferential side and flexional outer circumferential side during bending of said portion; each of said side plates includes a flexional inner circumferential side residing during bending on said flexional inner circumferential side of said bend; each of said side plates includes an outer circumferential side residing during bending on said outer flexional circumferential side of said bend; connecting plates bridged over each of said bending inner circumferential sides and each of said bending outer circumferential sides of each of said pairs of said right and left spaced side plates; said side plates include front and rear side portions; said side plates being offset at said front and rear side portions thereof; a cable is protected and guided in a cable accommodating space formed of said plurality of flexibly connected side plates and said connecting plates; each of said side plates includes short arc-shaped warp limiting lock grooves oriented in an arc path coaxially spaced from said connecting pin; each of said side plates includes short arc-shaped warp limiting lock pieces oriented in an arc path coaxially spaced from said connecting pin; said short arc-shaped warp limiting lock pieces engage said short arc-shaped warp limiting lock grooves in a concave element/convex element relationship; and said short arc-shaped warp limiting lock pieces and said short arc-shaped warp limiting lock grooves reside on opposed surfaces of said side plates connected in the longitudinal direction so that warping in said front side portions and said rear side portions of said side plates in a width direction is limited.
