Abstract

PURPOSE: To surely prevent a vertically-moving body from dropping off, by hanging driven members not to slide and by driving the driven members by the falling weight of the vertically-moving body.
CONSTITUTION: A first lever 26 is hung with a rope pulley 23 and a rope 9. When the vertically-moving body 2 drops off, the part of the first lever 26 coupled to the body 2 rocks up to move up second wedges 22a, 22b together with levers 24, 25. Since first wedges 21a, 21b fall together with the body 2, the second wedges 22a, 22b are elevated with an inertial mass corresponding to the weight of the vertically- moving body 2 relatively to the first wedges 21a, 21b. Therefore, the second wedges 22a, 22b are driven in between the first wedges 21a, 21b and a guide rail 13 by a strong force corresponding to the falling mass.
