Ladder-based cart apparatus

摘要

A ladder-based cart apparatus includes a first ladder assembly and a second ladder assembly. A pair of wheel assemblies are supported by first ladder assembly at preselected positions along the first ladder assembly. Adjustable connection assemblies connect the wheel assemblies to the preselected positions along the first ladder assembly. Each connection assembly has a height which is less than respective widths of first lateral support members of the first ladder assembly so that translation of the second ladder assembly with respect to the first ladder assembly is not interfered with by the connection assembly. A first platform assembly, connected to distal ends of second lateral support members of the second ladder assembly, includes a hinge assembly connected to the distal ends of the second lateral support members. A first platform element is connected to the hinge assembly. A stop element is connected to a bottom side of the first platform element. The stop element includes a fixed portion connected to the first platform element and a free-end portion projecting from the fixed portion at a predetermined obtuse angle. A strap assembly is connected to the first platform element for connecting the apparatus to a tree. A lock assembly is connected to each of the second lateral support members, for securing the stop elements when the first platform element is in a horizontal orientation. In addition, a folding, cable-supported, horizontally orientable, second platform assembly can be connected to the second ladder assembly.
