Abstract
An integrated interlock and homing device for a rail assembly. The interlock includes a number of stacked locking bars located adjacent to the rails and a separate locking slide mounted adjacent to each rail in alignment with the locking bars. The homing device includes a separate pivot arm mounted to each rail that moves between open and closed positions when the corresponding rail is extended or retracted. The pivot arm includes an actuator pin that operates the corresponding locking slide. When the homing device is opened, the arm and actuator pin move the locking slide into a locked position thereby locking the locking bars and preventing additional rails from being opened. When the homing device is closed, the arm and actuator pin move the locking slide into an unlocked position thereby releasing the locking bars.
