Cable protection and guide device

Abstract

A cable protection and guide device comprising a number of pairs of right and left spaced side plates articulately connected to each other in a longitudinal direction wherein the plates are identical and interchangeable. Each of the link plates includes an arc shaped concavity, a convex portion and, the convex portion of the next adjacent link plate interengages the arc shaped concavity of the link plate. The arc shaped concavity includes a warp limiting lock groove and the convex portion includes an arc-shaped warp limiting lock piece The arc-shaped warp limiting lock piece of the convex portion interengages the arc-shaped warp-up limiting groove of the arc shaped concavity of link plate so that the warping of the link plates is substantially eliminated. The manufacturing cost for a single link plate used in a cable protection and guide device is reduced by half.

1 . A cable protection and guide device, comprising,
 a number of pairs of right and left spaced side plates articulately connected to each other in a longitudinal direction enabling said side plates to form a flexional circumferential bend having a flexional inner circumferential side and flexional outer circumferential side;   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 and an outer circumferential sides side residing during bending on said outer flexional circumferential side of said bend;   each of said link plates includes a front side portion and a rear side portion;   connecting plates;   said connecting plates are respectively bridged over said bending inner circumferential side and said bending outer circumferential side of said pairs of right and left spaced link plates;   connecting pins residing in said front side portion of each of said link plates;   said link plates include connecting pin holes (recesses) in said rear side portion of each of said link plates;   a cable accommodating space formed by pivotally connecting said link plates to the next adjacent link plates in a longitudinal direction of the cable;   a cable resides within said cable accommodating space, and, said link plates are identical and interchangeable.   
   
   
       2 . A cable protection and guide device according to  claim 1 , wherein each of said link plates includes:
 an arc shaped concavity;   a convex portion; and,   said convex portion of said next adjacent link plate interengages said arc shaped concavity of said link plate.   
   
   
       3 . A cable protection and guide device according to  claim 1 , wherein each of said link plates includes:
 an arc shaped concavity;   said arc shaped concavity includes a warp limiting lock groove;   a convex portion;   said convex portion includes an arc-shaped warp-up limiting lock piece; and,   said arc-shaped warp limiting lock piece of said convex portion of said next adjacent link plate interengages said arc-shaped warp-up limiting groove of said arc shaped concavity of said link plate so that warpage of said link plates is substantially eliminated.   
   
   
       4 . A cable protection and guide device according to  claim 2 , wherein:
 said arc shaped concavity includes a warp-up limiting lock groove;   said convex portion includes an arc-shaped warp-up limiting lock piece; and,   said arc-shaped warp-up limiting lock piece of said convex portion of said next adjacent link plate interengages said arc-shaped warp-up limiting groove of said arc shaped concavity of said link plate so that the warpage of said link plates is substantially eliminated.
