Abstract
A cargo carrier for movably supporting cargo includes a frame configured to support cargo at the cargo carrier and at least two wheels at each side of the frame. Each of the wheels is rotatably mounted to a respective support arm. The support arms are pivotally mounted to respective sides of the frame and are pivotable relative to the frame to adjust at least one of a height and tilt of the frame relative to a support surface. The cargo carrier is readily adapted to position the frame at a lower position for road applications and a raised position for uneven terrain applications. The cargo carrier may include a deck that is movably mounted to the frame and is longitudinally movable along the frame.
Claims23
A cargo carrier for movably supporting cargo, said cargo carrier comprising:
- a frame configured to support cargo at said cargo carrier;
- at least three wheels at each side of said frame, each of said wheels being rotatably mounted to a respective support arm, said wheels being independently mounted to the respective support arms with no common axle extending across said frame and associated with corresponding wheels at opposite sides of said cargo carrier;
- and
- said support arms being pivotally mounted at respective sides of said frame and being independently pivotable relative to said frame to adjust both the height and tilt of said frame relative to a support surface, said cargo carrier being readily adapted to position said frame at (a) a plurality of lower travel positions in which each of said at least three wheels at each side of said frame supports at least a portion of said frame on the support surface as the cargo carrier travels along the support surface and (b) a plurality raised travel positions in which at least one of said wheels at each side of said frame is raised above the support surface relative to the others of said wheels as the cargo carrier travels along the support surface.
A cargo carrier for movably supporting cargo, said cargo carrier comprising:
- a frame;
- a deck movably mounted to said frame and longitudinally movable along said frame, said deck being configured to support cargo at said cargo carrier;
- and
- a support system for movably supporting said frame and said deck above a support surface, said support system including a pair of forward support arms pivotally mounted to respective sides of said frame, a pair of center support arms pivotally mounted with respect to respective sides of said frame, and a pair of rearward support arms pivotally mounted to respective sides of said frame;
- each of said forward and rearward support arms and said center support arms extending from said frame and having a respective wheel rotatably mounted at an end thereof, said forward support arms being pivotable relative to said frame to adjust a height of a forward portion of said frame relative to the support surface, said rearward support arms being pivotable relative to said frame to adjust a height of a rearward portion of said frame relative to the support surface, and said forward and rearward support arms being pivotable to raise the height of said frame so as to raise the wheels associated with said center support arms above the support surface;
- and
- wherein said forward and rearward support arms are configured to position said frame at a plurality of first ride heights in which the wheels associated with said forward and rearward su ort arms support the frame at the support surface as said cargo carrier travels along the support surface and in which the wheels associated with said center support arms are raised relative to said wheels associated with said forward and rearward support arms, and wherein said forward and rearward and center support arms are configured to position said frame at a plurality of second ride heights in which the wheels associated with said forward and rearward and center support arms all support the frame at the support surface as said cargo carrier travels along the support surface.
