Abstract
A system with a base may be mounted on a vehicle, and a carriage assembly that may be movably connected to the base and may move with respect to the base. The carriage assembly may include a motor including a motor output shaft and motor housing, and a driving mechanism may couple to a door and to the motor output shaft or the motor housing. The carriage assembly may also include a coordination bar may be coupled to the motor output shaft or the motor housing, the motor output shaft or the motor housing may rotate the coordination bar responsive to operation of the motor. At least one linkage assembly may extend or retract to move the carriage assembly to move the door between an open position and a closed position based on rotation of the coordination bar.
Claims16
A system comprising:
- a base configured to be mounted on a vehicle above a door;
- a carriage assembly configured to be movably connected to the base and configured to move with respect to the base, the carriage assembly comprising a motor including a motor output shaft and a motor housing configured to rotate in opposite directions during movement of the door, a driving mechanism configured to couple to the door and to couple to the motor output shaft for movement of the door in a longitudinal direction in response to operation of the motor, and a coordination bar configured to be coupled to the motor housing, the motor housing configured to rotate the coordination bar responsive to operation of the motor to move the door in a lateral direction;
- and
- at least one linkage assembly configured to be coupled between the base and the coordination bar, the at least one linkage assembly configured to extend or retract to move the carriage assembly with respect to the base to move the door between an open position and a closed position based on rotation of the coordination bar, the at least one linkage assembly including a lever configured to be fixedly coupled to the coordination bar and a linkage arm configured to be pivotably coupled with the base, the lever and the linkage arm configured to move over center while the carriage assembly is extended with respect to the base to form an over center lock.

A system comprising:
- a base configured to be mounted on a transit vehicle above a door;
- a carriage assembly movably connected to the base and configured to move with respect to the base, the carriage assembly comprising a motor including a motor output shaft and a motor housing configured to rotate in opposite directions during movement of the door, a driving mechanism configured to couple to the door and coupled to the motor output shaft for movement of the door in a longitudinal direction in response to operation of the motor, and a coordination bar configured to be coupled to the motor housing, the motor housing configured to rotate the coordination bar responsive to operation of the motor to move the door in a lateral direction between an open position and closed position;
- a lever coupled to the coordination bard and
- a linkage arm configured to be pivotably coupled with the base, the lever and the linkage arm configured to move over center when the carriage assembly is extended with respect to the base to form an over center lock.

A system comprising:
- a base configured to be mounted on a transit vehicle above a door;
- a carriage assembly movably connected to the base and configured to move with respect to the base, the carriage assembly comprising a motor including a motor output shaft configured to rotate in a first direction and a motor housing configured to rotate in a second direction opposite the first direction, a driving mechanism configured to couple to the door and coupled to the motor output shaft for movement of the driving mechanism in the first direction and the door in a longitudinal direction in response to operation of the motor, and a coordination bar configured to be coupled to the motor housing for rotation of the coordination bar in the second direction to move the door in a lateral direction responsive to operation of the motor;
- and
- at least one linkage assembly coupled between the base and the coordination bar and configured to extend or retract to move the carriage assembly with respect to the base to move the door between an open position and a closed position based on rotation of the driving mechanism in the first direction and rotation of the coordination bar in the second direction, the at least one linkage assembly including a lever configured to be fixedly coupled to the coordination bar and a linkage arm configured to be pivotably coupled with the base, the lever and the linkage arm configured to move over center while the carriage assembly is extended with respect to the base to form an over center lock.
