US Patent 8109526 Convertible A-frame cart

A cart comprises a first pillar that is mounted on a platform and defines first and second load supporting surfaces. A second pillar is mounted on the platform defining a third and fourth load supporting surfaces. The first and third load supporting surfaces are coplanar and the second and fourth load supporting surfaces are coplanar such that the first and second pillars form an A-frame support structure. Movable platforms are connected to the pillars and are movable between a raised position and a lowered position. When the movable platforms are in the lowered position, they are coplanar and form a support surface. Hangers are pivotably attached to the first pillar and are movable between a retracted position and an extended position.
