ABSTRACT:
A collapsible and extendable protective cover mechanism for storage areas includes a pair of elongated guide tracks positioned in parallel relation on either side of the area to be protected. A plurality of cover segments, each having side portions interconnected by a top portion are positioned with the lower extremities of the side portions in guided engagement with the elongated track means. A power actuator system is interconnected with at least one of the cover segments and, when energized, causes simultaneous movement of the side portions of at least one of the segments, causing the protective cover mechanism to move toward a collapsed position where a majority of the area is exposed or an extended position where substantially all of the area is covered and protected. A single drive motor of the power actuator mechanism functions through a chain drive to cause simultaneous rotation of threaded members that are secured at either side of the area to be protected. An internally threaded connecting element is received by the rotatable threaded elements and is movable linearly upon rotation of the threaded elements. Threaded pins establish connection between the lower portions of at least one of the cover segments and the linearly movable connector element, thus resulting in linear movement of the cover segments upon selective energization of the drive motor.
