A retractable cover system includes laterally spaced apart guide rails that each provide a track. A drive assembly includes a motor operatively connected to a gear. A cover has multiple slats configured to interlock with one another in a deployed configuration. The slats cooperate with the gear and are slidable in the tracks between first and second positions within the opening in response to actuation of the drive system. The slats are stacked onto one another in a stowed configuration. A method of servicing a retractable cover system includes the step of removing an access cover from a magazine to expose a cavity housing stacked rigid slats. A method of retracting a tonneau cover includes the steps of actuating a handle and decoupling the tonneau cover from a drive mechanism.

A truck cap assembly that selectively covers a truck bed of a truck is provided. The truck cap assembly may include a cap that sets on opposing side walls of the truck; a cap door located on the cap; a latch bar located on the cap; a controller located on the cap door; and a latch release assembly which includes a motor and a latch arm. The controller is in electrical communication with a motor actuator that is coupled to a latch arm. A signal from the controller activates the motor to move the latch arm. The latch arm is releasable from the latch bar to release the cap door.

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.

Sliding tarp systems employed on trailers are disclosed. Various systems and improvements are disclosed which allow for unobstructed access to the tarp storage area and more reliable operation of the sliding tarp system. Unobstructed access to the storage area is achieved by providing extensions to the sliding tarp system tracks which the sliding tarp system support elements can be slid onto, leaving the storage area completely uncovered. The sliding tarp system track extensions can be removed or reoriented when not in use.

The invention relates to an openable structure for a substrate, such as a lorry, trailer, semitrailer, railway wagon, dumper truck or container, comprising a tarpaulin framework to which, for example, a tarpaulin made of weather-resistant material or a plurality of hingedly couplable wall elements can be connected, wherein the tarpaulin framework has a plurality of slides which are shiftable along at least one guide, wherein the guide comprises a longitudinal member element along which the slides are shiftable. An openable structure permitting smooth opening and closing of the structure is provided according to the invention in that the longitudinal member element is arranged adjustably at least in sections in a direction transversely with respect to the shifting direction of the slides.

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 convertible wheel is described that is interchangeably used with at least two different car plate designs and tracks. In particular, there is provided a wheel for use with a bearing and a car plate in a tarpaulin system. The wheel comprises a cylindrical body with a groove, first face, an opposed second face, and a central cavity positioned therebetween for receiving the bearing therein. The first face has a first opening with a first diameter, and the second face has a second opening with a second diameter that is smaller than the first diameter. Either the first face or the second face can be positioned facing the car plate.

A tarpaulin system for an open cargo hold. The tarpaulin system includes a tarpaulin, a plurality of bows, a plurality of connectors, a cable, and a tail end system. The plurality of connectors connects the plurality of bows to the cable while the tarpaulin is draped atop the plurality of bows. The tarpaulin bracket system allows for quick, and easy, replacement, or fixing, of the plurality of connectors or damaged bows allowing for much easier and efficient replacement while traveling in harsh environments.
