Abstract: A rail system for mounting a tarp enclosure to a platform, comprising a rail body having a channel and a bumper beneath thereof, and a carriage displaceable along the channel and attachable to the tarp enclosure so as to position the tarp enclosure over the rail body. A tubing system for the tarp enclosure, comprising a first member having four first tracks sized to slidably receive a cordon of the tarp enclosure, a second member having four second tracks sized to slidably receive the cordon, a tubing connector having four connector tracks sized to slidably receive the cordon. There is also provided a method for assembling a tubing assembly, comprising joining the first and second members to the tubing connector such that any one of the first tracks is in communication with a one of the second tracks via a one of the connector tracks.

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.
