Abstract
A device configured for installation behind rear wheels of a truck or trailer includes a cross frame pivotally attachable to frame rails, at least one panel holder comprising a structural member having first and second planar portions joined at an angle relative to one another, and at least one panel attached to the panel holder. Bearings, holder straps, and support brackets facilitate attachment of the device to the frame rails.
Claims20
A device installed behind rear wheels of a truck, the truck having a plurality of frame rails with a space between the frame rails and a set of rear wheels positioned below the frame rails, the device comprising:
- a cross frame pivotally attached to the frame rails of the truck at an upper end of the cross member;
- at least one panel holder comprising a structural member having first and second planar portions joined at an angle relative to one another attached to the cross member at a lower end of the cross member, the lower end of the cross member opposite the upper end thereof;
- and
- at least one panel attached to the at least one panel holder, the at least one panel extending laterally from one lateral end of the truck to an opposing lateral end of the truck.
A device installed behind rear wheels of a truck, the truck having a plurality of frame rails with a space between the frame rails and a set of rear wheels positioned below the frame rails, the device comprising:
- a cross frame pivotally attached to the frame rails of the truck at an upper end of the cross member;
- at least one panel holder comprising a structural member having first and second planar portions joined at an angle relative to one another attached to the cross member at a lower end of the cross member, the lower end of the cross member opposite the upper end thereof;
- and
- at least one panel attached to the at least one panel holder, the at least one panel extending laterally from one lateral end of the truck to an opposing lateral end of the truck, wherein the cross frame comprises a continuous sheet of material that fills a space between the frame rails and wherein the cross frame is installed between about 30% to about 60% of a distance between the rear tires and a truck bumper.
A device installed behind rear wheels of a truck, the truck having a plurality of frame rails with a space between the frame rails and a set of rear wheels positioned below the frame rails, the device comprising:
- a cross frame pivotally attached to the frame rails of the truck at an upper end of the cross member, wherein the cross frame comprises a tubular element at the upper end thereof extending laterally between the frame rails;
- at least one panel holder comprising a structural member having first and second planar portions joined at an angle relative to one another attached to the cross member at a lower end of the cross member, the lower end of the cross member opposite the upper end thereof;
- and
- at least one panel attached to the at least one panel holder, the at least one panel extending laterally from one lateral end of the truck to an opposing lateral end of the truck, wherein the cross frame comprises a continuous sheet of material that fills a space between the frame rails and wherein the cross frame is installed between about 30% to about 60% of a distance between the rear tires and a truck bumper, wherein the cross frame comprises a holder strap at each lateral end of the cross frame, the holder strap having an adjustable loop at an upper end thereof, the bearings attached to the cross frame via the adjustable loops.
