ABSTRACT:
A mobile home jack and coupler assembly is adapted for mounting to the A-frame or tongue of a mobile home. Both top mounted coupler assembly and inverted bottom mounted coupler assembly are disclosed. Each includes a screw jack which mounts from underneath. The screw jack carries, adjacent its lower end, a mounting plate which is received in underlying relation to a portion of the coupler, while the upper end thereof extends through a guide plate above the coupler. The mounting plate on the jack is welded to the jack body by an underlying weld, with the result that the tongue weight of the mobile home is carried directly by the jack support plate in compression, rather than in tension, and the compressive force is transferred by the underlying weld, also in compression, to the jack body. As a result, jack mounting screws do not carry the tongue weight applied to the jack, and greater tongue loads can more safely be carried.
