ABSTRACT:
A simple trailer frame is provided which may be included within a structure and which allows the frame or the structure to be easily and quickly converted into a mobile trailer on retractable wheel assemblies. When the frame is used within a structure, once the structure is at its use site it need show very little evidence that it was a trailer. Also included in the frame is a towing member receiving member for quick and easy attachment and detachment of a towing member to the frame. A mechanical linkage is provided within the frame so that proper connection of the towing member to the frame locks the extended wheel assemblies in place. Towing is only possible when wheels are properly extended and locked. As a safety precaution, the design may also include a provision so that the locking mechanism cannot be deactivated unless the weight of the frame has been removed from the wheel assemblies. Self-contained lifting and lowering components such as jacks, may also be included as an integral part of the frame or the structure.
