Abstract: A folding drop leg for a trailer jack for supporting a trailer jack where added length is needed. The folding drop leg includes a base plate, a automatic locking swing plate, and a leg. The base plate is mounted to the bottom of the trailer's existing jack. The automatic locking swing plate is mounted to the base plate by use of a hinge pin and is swung upward when towing and dropped down to provide a stand for supporting the trailer when disengaged from the tow vehicle. The leg is mounted to the bottom of the automatic locking swing plate to add additional length to the existing jack leg rapidly when needed.

Abstract: A self-locking scissor coupler, provision for holding guide poles, for attaching a trailer to a trailer hitch ball. The coupler includes a body, a pair of movable jaws, and a bail. The body attaches to the trailer. The pair of movable jaws are pivotally mounted to the body and normally biased open. The bail is pivotally mounted to the body and normally biased down so as to allow the pair of movable jaws to be normally biased open when the bail is lifted up and disengaged from the pair of movable jaws, and when the pair of movable jaws are engaged by the trailer hitch ball, the pair of jaws close causing the bail to drop, engage the pair of movable jaws, and maintain the pair of jaws closed, thereby automatically capturing the trailer hitch ball in the pair of movable jaws.
