ABSTRACT:
A trailer designed to be towed behind a vehicle with a frame that is slidably attached to the trailer body. Inclined ramps are formed on the members of the frame such that when the frame slides rearward relative to the trailer, rollers on the underside of the trailer body cause the trailer to rotate about the axle. The slidable connection between the trailer and the draw bar yoke is slightly negatively inclined to insure that the mechanism will move freely and to enable the trailer to be returned to the horizontal position by merely applying a forward force on the frame. The invention also employs means to secure the trailer body to the frame when the trailer is in its normal horizontal position.
