Abstract
Abstract A cable cylinder device comprises a substantially elongated housing having opposite end walls at the opposite ends of its length and a plurality of elongated side walls extending along its length between the end walls. A thrust roller in the housing has a support plate and first roller means rotatably mounted on the plate and second roller means rotatably mounted on the plate in spaced relation with the first roller means. A first guide roller in the housing is rotatably affixed to one of the end walls. A second guide roller means in the housing is rotatably affixed to the other of the end walls. A cylinder in the housing is affixed to one end wall of the housing and extends in the direction of the length of the housing. A piston rod is coaxially movably mounted in the cylinder and is affixed at one end to the support plate of the thrust roller. A cable in the housing is affixed at one end to an end wall, passes over the first roller means of the thrust roller, the first guide roller means, the second guide roller means, the second roller means of the thrust roller and is affixed at the other end to a side wall. A load bracket means affixed to the cable means in the area thereof between the first and second guide roller means whereby when the piston rod moves out of the cylinder in a predetermined direction, the thrust roller moves with it and the load bracket moves with the cable means in the opposite direction and when the piston rod moves into the cylinder in the opposite direction, the thrust roller moves with it and the load bracket moves with the cable means in the predetermined direction.
