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 detachable wheel assemblies, without the need for tools. The components and assemblies are also quickly and easily removed from the structure without the need for tools. 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 without the need for tools. A mechanical linkage may be provided in the frame in combination with wheel receiving members so that proper connection of the towing member to the frame locks the wheel assemblies in place on the frame. As a safety precaution, the design may also include a provision so that the towing member cannot be secured to the structure unless the wheel assemblies are fully and properly locked to the frame. Details of wheel assemblies, light assemblies and other trailer components which are quickly and easily removably attached to the trailer system or frame by a single individual without the need for tools are provided. Self-contained lifting and lowering components, such as jacks, may also be included as an integral part of the frame or the structure.
