Abstract
PURPOSE: To turn this device positively and reversely, and to make it function to prescribed load, by installing a movable ratchet with a fixed ratchet, by energizing the movable ratchet to the fixed ratchet side by means of a spring and by pressure welding connecting both ratchets.
CONSTITUTION: A tooth portion 4a with the same shape as a fixed ratchet 2 is formed to an opposite surface at the fixed ratchet portion 9 side of a movable ratchet 3, a coil spring 11 is insertion mounted to a pivot 1 between the movable ratchet 3 and a side plate 7a, and the movable ratchet 3 is energized ot the fixed ratchet 2 side by the spring force of the coil spring 11, thus pressure welding connecting tooth portion 4a, 4b. Consequently, load can be moved up and down because the movable ratchet 3 shifts to a side plate 7 against the force of the spring by turning a handle 14 and rotates sliding to the fixed ratchet 2. When the movable ratchet is stopped on its way, load does not fall because the resistance force of the pressure welding connection of the tooth portions 4a, 4b is larger than load.
