A two door assembly (10) for an elevator car (11) includes a high speed door (12) and a low speed door (14) that move between an open and closed position to close the entrance (16) of the elevator car. The doors (12, 14) are retained slidably between a header (18) disposed along the top of the car entrance and a door guide (20) disposed along the bottom of the car entrance (16). A drive mechanism (22) moves the high speed and low speed doors (12, 14) between the open and closed positions. A drive arm (24) interconnects the doors to move the low speed door (14) at approximately one-half the speed of the high speed door (12) driven by the drive mechanism (22). One end (38) of the drive arm (24) is connected pivotally to the door guide (20) of the elevator car (11). Each door (12, 14) has a pin (32, 34) extending from a bracket (26, 28) connected to each respective door for sliding engagement with a pair of slots (42, 44) that extend longitudinally along the drive arm (24). The length of the slots (42,44) are sufficient to permit movement of the doors (12, 14) between the open and closed positions. The weight of the drive arm (24) at a predetermined center of gravity (50) provides a predetermined closing force (F.sub.HC) to the high speed door (12) in the closed position and a reduced closing force (F.sub.HO) to the high speed door in the open position.
