Abstract:
A retractable cargo support system for an open truck, the system comprising:at least two horizontal members capable of being spaced apart in an extended position and stacked together in a retracted position on each of at least two opposing sides of an open truck; at least two vertical members between the at least two horizontal members on each of the at least two opposing sides of the open truck, each of the at least two vertical members pivotally connected to a first of the at least two horizontal members by a pivot means at a first end of the vertical member and each of the at least two vertical members slidably connected to a second of the at least two horizontal members by a slide means at a second end of the vertical member so that the at least two vertical members are capable of being oriented in a vertical position between the at least two horizontal members in the extended position to form a vertical support wall on each of the at least two sides of the truck and further capable of pivoting downwardly away from the vertical position in the retracted position; a cross brace member attachable at a pivot end by a pivot means to each end of an upper one of the at least two horizontal members so that the cross brace member is capable of being pivoted away from the at least one of the horizontal member on a first side of the truck to contact the cross brace member from the second side of the truck thereby defining an overlap portion on each of the brace members; a means for securing together the cross brace members so that they each form a rigid structural connection between the vertical support walls on each of the at least two sides of the truck; a vertical brace attached at a first end by a pivot means to each end of a first of the at least two horizontal members, the vertical brace being capable of pivoting between a horizontal orientation in the retracted position and a vertical position in the extended position, the vertical brace having a second end capable of being attached by a vertical brace attaching means to a second of the at least two horizontal members to form a vertical brace at each end of each of the vertical support walls.
