ABSTRACT:
An apparatus and a method of using the apparatus for supporting and immobilizing a trailer, especially a detachable trailer towed by a motor vehicle. The apparatus is attached to the trailer frame, one unit attached either in front, or behind each of the rear wheels. The apparatus is comprised of an elongated support or "jack" pivotally attached to the trailer frame and having a ground engaging foot. For travel, the support pivots to a horizontal position and is locked to the trailer frame. When the trailer is to be immobilized, the support pivots downward until it contacts the ground. The trailer is then rotated against the support by using the towing motor vehicle to tow the trailer forward against the support causing the support to pivot to its fully deployed vertical position perpendicular to the trailer frame. The trailer is now fully supported by the invention and the wheels of the trailer have been raised off the ground. The support can be locked in this vertical position. In addition to providing a stable support while the trailer is in storage or for working on or around the trailer and its contents, the supports of the invention provide anti-theft protection as the trailer cannot be moved while the supports are in their perpendicular, locked position. The invention can also be adapted for other types of land vehicles.
