ABSTRACT:
In an apparatus forming a combined hand truck and machine stand, a first frame support is pivotally coupled to a second frame support for movement between a first position forming a hand truck and a second position forming a machine stand. A machine support is pivotally coupled to the first frame support and is movable relative thereto between a first position forming the hand truck and a second position forming the machine stand. A base plate is pivotally coupled to a lower portion of the first frame support, and is movable between a first position pivoted outwardly relative to the first frame support and locked in place to prevent the apparatus from toppling when in the form of a hand truck, and a second position pivoted inwardly relative to the first frame support when the apparatus is in the form of a machine stand. The second frame support includes a pair of legs and a cross-piece support extending between and coupled for rotation to each leg. A plate defining a flat surface for engaging the machine support is fixed to the cross-piece support, and a handle is coupled to, and extends outwardly from the plate. When the apparatus is in the form of a hand truck, the plate engages the machine support to thereby prevent rotation of the cross-piece support and allow the handle to be used to move the hand truck. When the apparatus is configured as a machine stand, the cross-piece support forms a buttress for contacting and supporting the machine support.
