ABSTRACT:
This invention relates to a retractable cover system and, in particular, to such a cover system for use on truck load bodies. Retractable cover systems are known, the most simple being tent-like structures in which a fabric cover is loosely located over a framework. More complicated systems are also known in which substantially rigid cover shells are provided which are then hinged for movement between the open and closed positions. This invention provides a cover system which combines the simplicity of tent-like structures with the ease of use of the more complicated systems described above. The cover system of the invention comprises, in combination, a flexible sheet material cover and a structural framework defining the volume to be covered, the framework including a fixed frame rigidly supporting a track and a movable frame constituted by at least one transversely extending spreader movably supported on the track, the cover being adapted for location over the frame structure with one end thereof adapted for retention on the fixed frame and at least an opposite end thereof adapted for retention on the movable frame.
