Abstract

PURPOSE: To prevent a rope from damage, smoothen the rotation and improve the durability, by enabling the rope to be fit into a groove of a pulley at a constant angle at all times by attachng a drive pulley and a guide pulley in such positions as to enable them to freely shift in the axial direction with the rotations.
CONSTITUTION: By providing a drive pulley 18 which holds a rope 24 by keeping it wound in a spiral configuration by a groove 21, a guide pulley 13 on which this rope 24 is wound around, and also a carriage 25 which is fixed onto the rope 24 and shifts to the right and left, the pulley 18 and 13 are installed in such positions as to enable them to freely shift in the axial direction with the rotations. For instance, an angle θ1, which is formed by the groove 21 and the upper rope 24 connected to the carriage 24, and an angle θ2, which is formed by the lower rope 24 and the groove 21, are made to be equal to each other. When the drive pulley 18 is turned, the upper rope 24 starts becoming loosened and the lower rope 24 is wound, and by doing so, the carriage 25 is moved to the left. At that time, a shaft 17 moves to keep the both angles θ1 and θ2 equal to each other, and the pulley 18 is shifted. And therefore, the rope 24 is exempted from impininging upon the corner of the groove 21 and prevented from being damaged.
