Abstract

PURPOSE: To prevent the generation of noise by transmitting the motion of a wind pressure plate, moved by wind pressure, in the enlarged state to a closing body by connecting mechanism, and making the closing body open a sill clearance during the elevation of a car and close the sill clearance at the stop time of the car. CONSTITUTION: In a windless state, a wind pressure plate 12 is held in a nearly horizontal position, and a closing body 20 is placed in a nearly horizontal closing position. When the tip of the wind pressure prate 12 is inclined downward from a horizontal direction, the tip or the closing body 20 is inclined downward, so that the closing body 20 is placed in an opening position. In a sill clearance closing device 6 of such constitution, the wind pressure plate 12 receives strong wind pressure at the upper face during the ascent of a car. The wind pressure plate 12 is therefore pushed down, and a connecting rod is interlocked to rotate a cam 10 clockwise, so that the front end part of the closing body 20 is inclined downward through a claw 9. In the inclined state of the closing body 20, a clearance between the closing body 20 and a landing sill is opened wide when the closing body 20 passes near the landing sill of each floor. When the car is stopped, the wind pressure plate 12 does not receive wind pressure, so that the wind pressure plate 12 is placed in the horizontal state, and the closing body 20 closes the sill clearance so as to prevent the fall of some material into an elevator passage from the clearance.
