A tarpaulin superstructure is provided for use with a movable substructure, such as a truck, a trailer, a semitrailer, a railway wagon, a dump truck, or a container. The tarpaulin superstructure includes a top frame to which a tarpaulin made of weather-resistant material can be attached, where the top frame has multiple struts which can be moved along one or more guides, and where the end of the top frame has an end runner which can be raised to open the superstructure and lowered to close the superstructure. A tarpaulin superstructure is also provided where the end runner is not lifted by the airstream, as an air deflection part is arranged at an end of the end runner so that the airstream is converted into a force in the closing direction of the end runner.

A tarpaulin fastening device includes a support frame for support of one or more winch/spool assemblies and associated interconnecting line cord. The interconnecting line cord is extracted/retracted from/to its respective winch/spool assembly through actuation of a gear assembly. The interconnecting line cord is woven through eyelets of one or more connection pins and terminated with an anchoring mechanism. Once extracted from the winch/spool assembly, the interconnecting line cord is anchored to a flatbed trailer using the anchor mechanism and each connection pin is alternatingly connected to connection points along a length of tarp covering a payload supported by the flatbed and to connection points along a length of the flatbed trailer. Once the interconnecting line cord is anchored and connected to the tarp and flatbed, the tarp is secured onto the payload by actuation of the gear assembly.

A cover for a truck bed that can be horizontally traversed between expanded and collapsed positions is shown. Since the cover is horizontally traversed, the person manipulating the cover need not lift the cover vertically in order to reconfigure the cover between the expanded and collapsed positions. Women and elderly people who are generally not as strong as men can manipulate the cover.

A movable, tarp enclosure system includes a movable carriage having a main body and plural primary support wheels connected to the main body, at least one of the wheels being disposed at a first vertical level and at least one of the wheels being disposed at a being vertical level. The system also includes a support rail having a first and second support walls, the upper surfaces of which are respectively engaged by the carriage wheel(s) disposed at the first vertical level and at the second vertical level for movably supporting the movable carriage on the support rail.

The invention relates to a tarpaulin structure for an understructure, such as a truck, trailer, semi-trailer, railway car, dump truck or container, comprising a folding-top frame (16) and a tarpaulin (12) made of weather-resistant material, the folding-top frame (16) includes a plurality of struts (34); at the end, each of the struts has a carriage (32) that is movable along a guide (20), at least one bracket (36) is selectively pivotally connected to a pair of opposite carriages (32; 32) of the strut or to the strut (34); said bracket (36) forming a tarpaulin folding aid along with a bracket (26; 36) of an adjacent strut (34), of a pair of opposite carriages (32; 32) or of a stationary part (24) of the folding-top frame (16). In order to create a light-weight tarpaulin structure that allows an understructure to be reliably covered, according to the invention, the adjacent brackets (26, 36) are coupled to each other by means of a kinematic connecting rod assembly (38) that folds when the folding-top frame (16) is collapsed.

A roller tarp system for covering a truck bed includes a first pivot arm assembly pivotally coupled to one side of the truck bed and a second pivot arm assembly pivotally coupled to an opposite side of the truck bed. A generally hollow and cylindrical tarp spool extends along a longitudinal axis between opposite first and second ends. The tarp spool is rotatably coupled between the first and second pivot arm assemblies for rotatably supporting a flexible tarp cover. A drive assembly is housed within the tarp spool adjacent one of the first and second ends. The drive assembly is operatively coupled between one of the first and second pivot arm assemblies and the tarp spool for selectively rotating the tarp spool and actuating the tarp system between an open position uncovering the truck bed and a closed position covering the truck bed.

The invention relates to a tarpaulin structure for a substructure, such as a lorry, trailer, semi-trailer, railway car, dump truck or container, comprising a covering frame and a tarpaulin consisting of weather-resistant material, wherein the covering frame has a plurality of struts (34) which each have on the end sides thereof a carriage (32) that is displaceable along a guide (20), wherein at least one bow (36) is pivotally connected at each pair of opposed carriages (32; 32), said bow forming with a bow (36) of an adjacent carriage pair (32) a tarpaulin folding aid, the bows (36) of the tarpaulin folding aid being connected to each other. A tarpaulin structure that allows a reliable covering of a substructure while having a low intrinsic weight is achieved according to the invention in that the connected bows (36) comprise a pivot angle limiter (38) that allows only a limited pivoting of the bows (36).

A movable tarp enclosure system includes a tarp cover, support rails, a plurality of support bows connected to and supporting the tarp cover, and movable carriages connected to lower ends of said bows and which move along the support rails. Each of the support bows includes first and second main sections formed of rigid material and having hollow ends, and a corner member formed of rigid material which connects the first and second main sections together such that the main sections extend substantially perpendicular to each other. The corner member has end portions fitted into the hollow ends of the main sections, and the end portions each have an outer circumference with a size and shape that substantially corresponds to those of an inner circumference of the hollow ends of the main sections such that the end portions are stably connected within the hollow end portions by frictional engagement.
