  • Patent number: 4072337
    Abstract: A base construction is mounted on wheels and provided with a trailer hitch for towing purposes. Mounted above the base is a shelter construction comprising vertical longitudinal side walls pivoted to the base to fold inwardly and downwardly to horizontal position, thus minimizing the overall height of the trailer when traveling. A roof construction extends across the tops of the walls and is supported by releasable means connected between the walls whereby they may be released from the walls and roof construction to permit the walls to be folded inwardly. One end of the base extends beyond the associated end wall to form a porch and such end wall is pivotally supported at its upper edge to swing upwardly to a horizontal position to act as a cover or roof for the porch when the side walls are in vertical operative positions.
