Abstract: A retractable enclosure includes at least two displaceable structural bow frames which each define a roof section and opposed upwardly extending side sections. These sections are interconnected by joint connectors. The sections are also formed of extruded profiled straight metal tubes which have extruded interconnection channels. The tarp sections of flexible material are engaged by channels of some of the bow frames and collapse and expand as the bow frames are displaced closer or away from one another. Access to the enclosure can be provided from all sides thereof for access to its interior.

Abstract: A shield assembly is described for the cargo space of a transport vehicle wherein access to the cargo space is provided by a displaceable wall section mounted on a lower rail secured spaced from a lower side frame of the cargo space. The assembly comprises an elongated rectangular flexible seal guard having an elongated securable side edge section. The flexible seal guard has a width which is greater than a space defined between the rail and the lower side frame. The rail has a directional retention slot for immovably securing the securable side edge section of the flexible seal guard thereto whereby the flexible seal guard is supported for frictional engagement at an opposed free side edge against the lower side frame to substantially seal the space whereby to prevent foreign matter from entering into the cargo space.

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.
