Abstract:
1. A steerable trailer comprising: a main frame assembly having a longitudinal axis and including longitudinal frame members extending between front and rear ends of the main frame assembly, and further including at least one lateral frame member extending laterally between the longitudinal frame members; a main frame receiver bracket attached to the at least one lateral frame member of the main frame assembly; at least one connector receiver disposed on the main frame receiver bracket and positioned in alignment with the longitudinal axis of the main frame assembly; at least one wheel frame assembly including a wheel frame structure, a wheel frame assembly connector disposed on the wheel frame structure and at least a pair of wheels operably coupled to and supporting the wheel frame structure such that the pair of wheels remain at a constant angular orientation relative to the wheel frame structure, and wherein the wheel frame assembly connector is operably connected to and pivots about the at least one connector receiver; a main frame connector disposed on the main frame assembly and positioned in alignment with the longitudinal axis of the main frame assembly forward of the at least one wheel frame assembly; and a pivot frame assembly configured to be attached to a tow vehicle, the pivot frame assembly pivotably connected to the main frame connector and extending forwardly beyond the front end of the main frame assembly, wherein, at the front end of the main frame assembly, the pivot frame assembly contacts the main frame assembly on a bearing surface of the main frame assembly and is further configured to move laterally on the bearing surface in at least a generally lateral side-to-side direction relative to the main frame assembly, and wherein the at least one wheel frame assembly is capable of pivoting relative to the main frame assembly about the at least one connector receiver independently of the pivot frame assembly pivoting and moving in the generally lateral side-to-side direction relative to the main frame assembly.
