Abstract: The present invention provides an improved sliding curtain wall system for selectively closing an opening in a side of a covered trailer in which a plurality of elongate support members are slidably mounted to the side of the trailer to support several pieces of tarpaulin therebetween. Such a system allows the curtain wall to be easily opened and closed by sliding the support members along the length of the opening in the side of the covered trailer. Such a system also eliminates the need for straps and buckles to provide tension to the tarpaulin that forms the curtain.

A width adjustment mechanism is provided to provide usage with trailers or other open top containers of different widths. An improved seal is provided between the tarpaulin and container.

Abstract: A tarpaulin for a quick and safe covering of a load on a truck or trailer bed is provided having a post positioned at each corner of the bed including a pulley mounted on top of each post at the front of the bed. A pair of cables are each anchored at one end to an extensible cable holder, trained over the pulley and removably attached to the post on the back of the bed. The system and method includes a U-shaped tarpaulin using a plurality of eyes or pulleys for slidably connecting to the cables for covering the load positioned on the bed. The tarpaulin may be removed from all or part of the load. The system and method also includes independent extensible cable holders for lengthening and shortening each cable to lower and raise the tarpaulin.

Abstract: Disclosed is a covering system that includes plural supports and a cable. The cable may be advanced or retracted. The cable is connected, preferably by a fixed support, to a portion of the cover, whereby the cover may be advanced or retracted by moving the cable. At least some, preferably all, of the supports other than the terminal support are disposed in collars, the collars for the non-connected supports being threaded onto the cable. The collars and supports may be decoupled to permit removal of a support without the need to un-thread the collar and without the need to disturb other supports. The collars include plural separable cable sleeve portions that may be decoupled from one another to permit removal of the collar from the cable without un-threading the cable from other supports.

Abstract: A cargo blanket suspension system for a container comprises: a generally flat, horizontal framework of connected bars positioned within a cargo compartment of the cargo container. A cable system is connected to the framework to suspend the framework from or adjacent to the ceiling of the cargo compartment, to support a cargo blanket carried on the framework, and to permit raising and lowering of the framework and cargo blanket.

Abstract: A vehicle structure, especially a vehicle structure for utility vehicles such as motor vehicles and rail vehicles, wherein a covering frame is supported on a loading platform, covering a loading area. A roof skin can be placed on displaceable cross members of the covering frame, whereby at least one flexible reinforcing member is arranged in an upper area of the covering frame in order to reinforce the roof. The inventive vehicle structure has low deflection as a result of the fact that at least one flexible reinforcing member is fixed to a front corner area of the covering frame and to a rear displaceable cross member in the region of the longitudinal side thereof, at least one flexible reinforcing member being maintained in at least one point of traction in an area of the other longitudinal side.

Abstract: A retractable cover system for open top end containers, such as tractor trailers, is described. A tarp is wound on a drum and stored in a forward top end of the container. Opposed side seam portions of the tarp are secured to nylon pull cables and extend in guide channels secured adjacent top edges of opposed side walls of the container. The cables are secured together at a predetermined location and wound on a pulley whereby to pull the tarp from the drum in unison across the open top end. The drum is also secured to a pulley which is driven by a drive train assembly which also drives the cable pulley. The drive train assembly has a driven shaft and an idle shaft disposed in parallel and interconnected by a pair of sprockets which are secured on clutches.

Abstract: An endless cable tarp extension/retraction system spooled around front and rear pulleys includes drive components that are self-contained and encapsulated within an elongated housing that can be removably mounted to the container body using multiple clamp assemblies or mounting bolts disposed within a T-slot in the housing. A front idler pulley is provided that is sized and oriented relative to the drive pulley to maintain the upper and lower runs of the cable to travel essentially parallel along the length of the container. A self-tensioning rear idler pulley is provided that utilizes a spring to exert an adjustable force against the rear idler pulley. In another aspect of the invention, an anti-sail bracket extends downward from the bow ends of the tarp system and includes an inwardly projecting pin that is restrained from upward movement by a rail mounted to the side of the container.

Abstract: A retractable tarpaulin that can cover the cargo of a trailer (20), either partially or entirely. This system comprises a pair of posts (30) that slide in notches (24) at the periphery of a trailer bed (22), at the desired position according to the size of the cargo to cover. The width is also adjustable and includes an overhang (88) of up to 12″ on either side. The length may be reduced or extended at both front end and aft end if needed. The height of the posts can be adjusted to adapt to the cargo. A series of top cables (54) support the top tarpaulin (57) and a drum arrangement (55) stretches the cables to provide tightness to support the top tarpaulin when in use. As the top tarp is retracted a number of rings (86) attached to the tarp are successively engaged in a small vertical tube (53) and each section of the top tarp is sequentially piled into a small storage housing (52). The side tarp (75) is folded like a curtain into a horizontal support (83).

Abstract: A cover apparatus for an open-topped container such as a trailer or truck bed has a cover for extending over the open top of the container, a plurality of spaced, parallel bows extending between opposite sides of the cover, each bow having a guide at each end, an endless cable running through the guides at each end of each bow, a front one of the bows being secured to the cable and the guides on the remaining bows engaging slidably on the cable. A plurality of support pulleys support the cable to extend in a predetermined path along the opposite sides of,the container, and a pair of meshing gear drive pulleys control movement of the cable to extend and retract the cover. A reversible drive motor is linked to one of the gear drive pulleys.

Abstract: A flexible cover system for truck and trailer beds. The cover system includes first and second frameworks. A flexible cover is suspended between the frameworks by developing tension in the cover. Tensioning force is preferably applied to the cover using tension frames connected near the ends of the cover. Such tension can be developed using tensioning winches. A cover suspension member extends between the frameworks and can be detached at one or both ends to allow better access during loading. The cover has ribs connected to the cover at spaced locations. A framework can be collapsed or otherwise repositioned on the bed to improve access for loading and unloading. The invention also includes methods for converting the cover systems between closed and retracted conditions.
