ABSTRACT:
Trucks carried on a window track and mounting grippers operative to grip a retraction cord operative to when the tracks are deployed in a spaced relation, grip a retraction cord to be carried rearwardly toward the parked position when the cord is retracted. The grippers are operative upon the tracks reaching a parked position to release the cord for continued retraction of the cord relative to the parked truck so that continued retraction will draw the remaining tracks to parked position.
