CA 2385398

An electric door operator for controlling the opening and closing of a door pivotally mounted to a door frame of a multi-passenger mass transit vehicle is provided. The electric door operator comprises a gear sector having an aperture extending through a center portion thereof. The gear sector is mounted for rotation in opposite directions through opening and closing cycles of the door. A first supporting ring having a aperture extending through a center portion thereof is positioned adjacent to the gear sector such that the aperture of the first supporting ring is in alignment with the aperture of the gear sector to form an actuating assembly. A shaft member extends through the apertures of the gear sector and the first supporting ring. A push bar is suspended from the first supporting ring and is pivotally secured to a door lever. A driving means is provided for driving the actuating assembly such that the actuating assembly rotates about the shaft member and applies a force to the push bar for one of opening and closing the door. The operator is also designed such that it is capable of sequentially releasing a latching mechanism and then opens the door through the use of a single gear motor.
