An arm assembly for a cover system includes a force mechanism associated within a hollow arm of the assembly that includes a resiliently compressible element, such as a compression spring or gas spring, connected to one end of a cable. The opposite end of the cable is fastened to a non-circular pulley mounted to the container body, so that the cable is wound around the pulley as the arm pivots relative to the container body. As the arm pivots in a stowed direction, energy is stored by the compressible element, and releasing the stored energy causes the arm to pivot toward an extended or deployed position.

An embodiment provides a truck cover system that includes a side rail, a cover, and a latching mechanism. The latching mechanisms include a housing attached to the cover, a latch extending through a first end of the housing and configured to engage with a bottom portion of the side rail, a cap attached to a second end of the housing, a plunger attached to the latch and having a first plunger end partially extending through an opening of the cap, an anchor element attached to the first plunger end preventing the first plunger end from entering the housing, and a spring wrapped around the plunger. When the spring is compressed, the latch may disengage with the side rail, and, when the spring is uncompressed, the latch may engage with the side rail.

A cargo cover and strap system is provided that uses one tarp with two layers or two separate tarps, where one tarp is made of solid polyethylene waterproof material and the mesh net tarp is made of a woven fabric or woven polyethylene layer. The polyethylene tarp fits around cargo being transported in the bed of pickup truck. The mesh net is layered on top or joined together with the polyethylene tarp. Stretchable and easy-to-attach straps secure the mesh net tarp around the cargo by using a configuration of hooks at one or both ends of the strap for attaching anywhere into the woven mesh net tarp. The combination of mesh net tarp and the straps with hooks allow the mesh net to be pulled taut easily and simply by the straps to cover any configuration of cargo being transported.

A retraction system for a tonneau cover system, the retraction system includes: an adjuster shaft; a bias member disposed around the adjuster shaft; a drive roller in communication with the bias member; an adjuster configured to permit rotation of the bias member to increase or decrease an amount of force or torque provided by the bias member; a line connected to the drive roller and to one or more tonneau sections of the tonneau cover system, and a clamp that extends around the adjuster.

A sheet of flexible material can be deployed or stored by unfurling or furling the sheet using one or more inflatables. After the sheet is deployed to, for example, cover a load on a flatbed trailer, the inflatable can be deflated for storage. A sheet that has been removed from the load can be stored by placing an inflatable along an edge of the sheet. The inflatable is pressurized, and the sheet is furled onto the inflatable by rolling the inflatable. The inflatable is deflated and rolled up with the sheet for storage.
