Abstract

A car cam and locking roller locking structure that opens and closes elevator doors so that the lateral sliding of the car will not affect the opening of the doors. The invention is a mechanism to open and close elevator doors that is used to start the opening and closing operation of car door and boarding entrance door by moving forward end (4a) of car cam (4) furnished for car door (1) forward between a pair of locking rollers (14a) and (14b) furnished for boarding entrance door (13) so that it nearly touches looking roller (14a), while at the same time moving the other locking roller (14b) to grip car cam (4). Step-shaped part (40) is formed in locking roller, and at the same time, catch (50), which catches the step-shaped part to prevent its coming loose, is formed in car cam (4).

Description

technical field [0001] The present invention relates to an elevator door apparatus which opens the car door and the hall door when the elevator car reaches a floor. Background technique [0002] To open and close the car and hall doors when the elevator car arrives at a floor, a car cam mounted on the car door engages locking rollers mounted on the hall door. When the car door is opened by the door operating device installed on the car, the hall door is opened via the above-mentioned car cam and locking roller. [0003] As shown in FIG. 11 , a door hanger 2 is mounted on the top of the car door 1 . The door hanger 2 is suitably supported so that it can slide freely on a door guide (not shown) via rollers 3 . A support 6 with a pin 5 is mounted on the door hanger 2 . A car cam 4 is supported in a freely pivotable manner via the pin 5 , wherein the car cam has an L-shaped cross section and a T-shaped end protruding vertically. [0004] As shown in FIG. 12 , the car cam 4 i...
