Closed cable drag chain
First Claim
1. A closed cable drag chain into which a cable is inserted to be held and guided, comprising, a number of intermediate frames articulately connected to each other, an outer frame including a removable opening/closing frame structures each of which fit-covers a coupled portion of the adjacent intermediate frames to close the coupling gaps respectively thereby engaging it in a tubular shape, elastic sealed portions which closely fit said outer frame and said intermediate frame are formed on the inside of the front end and the inside of the rear end of each of said outer frame structures, said intermediate frames each comprises an intermediate frame body in which a cable holding groove is provided and an opening/closing lid member fitted into said cable holding groove, and, said intermediate frame body includes lower open end surfaces which abut with each other on the chain bend inner peripheral side to hold a required bending position of the chain and upper open end surfaces which abut with each other on the chain bend outer peripheral side to hold a straight extended position of the chain.

Abstract
To provide a closed cable drag chain, which is capable of preventing the contact wear powder generated in holding and guiding the cable or the like from being scattered by reliably closing the cable or the like, and wherein the assembling, maintenance and repair are easy while having light weight and low noise. In a closed cable drag chain into which a cable or the like is inserted to be held and guided in conditions where a number of intermediate frames (10) are articulately connected to each other, an outer frame (20) including a removable opening/closing frame structure fit-covers a coupling portion of the adjacent intermediate frames (10) to close the coupling gaps S respectively thereby coupling it in a tubular shape, the intermediate frame (10) comprises an intermediate frame body and an opening/closing lid member (12) fitted into the intermediate frame body (11), and the intermediate frame body (11) includes lower open end surfaces (11b), which abut with each other on the chain bend inner peripheral side to hold a required bending position of the chain and upper open end surfaces (11c), which abut with each other on the chain bend outer peripheral side to hold a straight extended position of the chain.
