Patent ID: 7150206

Claim:
A cable protection and guide device having a plurality of rotatably connected link bodies, each of said link bodies includes a pair of right and left side plates, each of said link bodies include connecting rods provided in a laterally bridged manner at an upper edge portion and a lower edge portion of said pair of right and left side plates, each of said side plates includes an interior and an exterior, each of said side plates includes a position limiting concave portion on said interior thereof; each of said side plates includes a position limiting convex portion on said exterior thereof, each of said side plates being rotatably connected between a linear position mode and a bending position mode by a connecting pin and pin hole arrangement with the side plates of the next adjacent link body, and a cable is protected and guided in a cable accommodating space formed in the connected plurality of link bodies, characterized in that said position limiting concave portion of said interior of said side plates includes a pair of abutting surfaces disposed in parallel with each other, said convex portion of said side plate includes a pair of linear position limiting surfaces disposed in parallel with each other and a pair of bending position limiting surfaces disposed in parallel with each other, each of said linear positioning surfaces is coterminous with one of said bending position limiting surfaces such that said linear position limiting surfaces and said bending position limiting surfaces form a substantially parallelogram shape; said linear position limiting surface of said link bodies is controlled by engagement of said abutting surfaces of said concave portions of said interior of said side plates with said linear position limiting surface of said convex portion of said exterior of said next adjacent side plate.
