Patent number: 7520122Abstract: A cable protection and guide device in which maintenance of cables is easily performed without completely removing a cable accommodating space extension arm from a side plate is disclosed. Inadvertent disengagement of the cable accommodating space extension arm is prevented because the arm strongly engages the side plates of the device. The cable protection and guide device includes a number of pairs of right and left side plates connected to each other. Cable accommodating space extension arms are bridged over the flexional inner circumferential sides of at least one pair of side plates. D-shaped pin hinge shafts in the hinge ends of the arms are detachably interengaged with a groove in one of the side plates and thus permits the arm to pivot with respect to the side plate. Hinge end side locking pawl pieces of the arms are interlocked to the side plates.Type: GrantFiled: February 7, 2008Date of Patent: April 21, 2009Assignee: Tsubakimoto Chain Co.Inventors: Seiji Kitagawa, Masaaki Ikeda, Shoichiro Komiya, Takayuki Matsuda
