A tarpaulin cover system includes a drive unit for moving the tarpaulin selectively into covering and uncovering positions. The drive unit comprises first and second drive sprockets and a rotatable actuator sprocket with all of the sprockets spaced from and out of contact with each other. An idler sprocket is provided between the actuator sprocket and the drive sprockets. All of the sprockets are interconnected by a chain engaged with teeth with the chain extending partially around each sprocket whereby rotation of the actuator sprocket causes the drive sprockets to move in the intended directions. This motion is transmitted to drive pulleys which drive cables to control the position of the tarpaulin.

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.

The invention relates to a tarpaulin superstructure for a movable substructure, such as a truck, a trailer, a semitrailer, a railway wagon, a dump truck or a container, comprising a top frame to which a tarpaulin made of weather-resistant material can be attached, wherein the top frame comprises a plurality of struts which can be moved along at least one guide, wherein the end of the top frame comprises an end runner which can be raised to open the superstructure and lowered to close the superstructure. A tarpaulin superstructure where the end runner is not lifted by the airstream is provided according to the invention in that an air deflection part is arranged at an end of the end runner, by means of which air deflection part the airstream is converted into a force in the closing direction of the end runner.

A rear corner element for a truck bed cover serve to guide rainwater exterior to the truck bed wall. The rear corner element has a mounting part and a cover part. The mounting part has a base mounting part adapted for being secured on top of the rear end of a side wall of the truck bed in elongated of a coupling rail adapted for mounting a roll-up truck bed cover to said side wall of the truck bed, a first front end part configured to be assembled to a free rear end of the coupling rail in lengthwise extension of said coupling rail, a first rear end part opposite the first front end part, and at least one rainwater diverting channel and/or chamber extending lengthwise of the mounting part from the rainwater inlet to the first rear end part.

A retractable cover system includes laterally spaced apart guide rails that each provide a track on either side of an opening. The retractable cover system further includes a cover that has multiple slats that are configured to interlock with one another in a deployed configuration. The slats are slidable in the tracks between first and second positions within the opening. The slats are stacked onto one another in a stowed configuration. The slats include laterally extending profiles that are complementary to one another and are configured to interlock with one another in a deployed configuration. The complementary profiles are configured to decouple from one another in the stowed configuration.

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 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 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 an actuator and a latch arm. The controller is in electrical communication with an actuator that is coupled to a latch arm. A signal from the controller activates the actuator to move the latch arm. The latch arm is releasable from the latch bar to release the cap door.

A rolling tarp deployment system includes a trailer, a bulkhead fixed to the trailer, first and second bows movable along the trailer, first and second tensioning assemblies, and a cover. The first tensioning assembly has a first member secured to the first bow, a second member secured to the bulkhead, and a first actuator configured to engage the first and second members to restrain the first bow to the bulkhead. The second tensioning assembly has a third member secured to the second bow, a fourth member fixed to the trailer, and a second actuator configured to engage the third and fourth members and move the second bow away from the bulkhead. The cover is tensioned when both the first and second members and the third and fourth members are engaged.

Removable roofing system comprising a motor inserted inside a drum (2), a cord, a compensation device (4), two rigging rails (5a, 5b), at least one guide arch (6a) and removable roofing, the at least one guide arch (6a) being connected to the cord and to the removable roofing, and being designed so that each of its ends slides in a rigging rail (5a, 5b), the cord passing along each rigging rail (5a, 5b) and through the compensation device (4) and being connected at its two ends to the drum (2) so that the rotating of the drum (2) by the motor causes the cord to move in a direction dependent on the direction of rotation of the drum (2), deploying or retracting the removable roofing by moving the at least one guide arch (6a), each rigging rail (5a, 5b) being equipped with at least one end pulley (21a, 21b) and with at least two corner-block deflecting pulleys (20a, 20b, 23a, 23b) which are designed to guide the cord from the compensation device towards the at least one end pulley (21a, 21b), and the compensation device (4) is designed to automatically compensate for variations in cord tension.
