Abstract:
A foldable trailer includes a substantially horizontal, substantially planar center section joined to at least one main axle and wheels assembly, at least one substantially planar rear section attached to the center section by a first hinged interface, such that the rear sections may be folded from a substantially horizontal position, coplanar with the center section, to a substantially vertical position relative to the horizontal center section, at least one substantially planar forward section attached to the center section by a second hinged interface, such that the forward sections may be folded from a substantially horizontal position, coplanar with the center section, to a substantially vertical position relative to the horizontal center section, a tongue section attached to an outermost forward section by a third hinged interface, such that the tongue section is enabled to fold downward around the third hinged interface, as the forward sections are folded, resulting in both the tongue section and the forward sections being oriented to a substantially vertical position relative to the center section, and a forward and a rear set of trolley legs, each set having trolley wheels. As the forward and rear sections are folded upward, the sets of trolley legs are deployed downward, lifting the folded trailer on the trolley wheels with the main axle and wheels assembly off ground level, such that the folded trailer may be moved about on the trolley wheels without interference from the main axle and wheels assembly.
