Abstract
A roller assembly including a roller and a support frame is removably mounted in a carrier attached to the floor of a vehicle. The roller is raised to an extended position so as to abut against a cargo unit load device when a roller drive system is activated and subsequently automatically lowered to a retracted position within the carrier when this system is deactivated. The roller is rotatably mounted on a support frame. Also mounted on this support frame is a DC motor which has an eccentric arm attached to its drive shaft. When the roller drive system is electrically activated, the DC motor as well as the roller drive motor are both activated, with the DC motor driving its arm against a post member to bring the frame to its extended position in the carrier. In this position, the roller is urged upwardly in abutment against the cargo unit load device. A capacitor is fully charged while the motors are activated. When the roller drive is deactivated, the capacitor is automatically connected to the DC motor to drive it in a reverse direction with the eccentric arm being rotated to permit the roller to fall to its retracted position.
