ABSTRACT:
A slidable cover assembly for merchandise carrying vehicle platforms is described. The cover assembly comprises a pair of opposed end support frames and a plurality of intermediate frames, each having a top carriage for displacement on a central horizontal top center beam member secured to the platform. Each end support frame and intermediate frames have a top tapered roof truss structure and opposed depending side members. The side members have a side rail engaging carriage at a lower end thereof for displaceable support engagement with a side rail secured to opposed sides of the platform. A tarp is secured to the end support frames and intermediate frames and displaceable therewith from a collapsed condition to an extended condition. Tarp displacement mechanisms are provided to displace the tarp side walls outwardly of the intermediate frames when the frames are displaced closer to one another from the extended condition to the collapsed condition. The end support frames have a vertical connecting wing flange disposed vertically along at least a portion of the opposed depending side members and adapted to be detachably secured to a locking mechanism secured to stationary opposed bulk head frames of the platform.
