Patent attributes
A jack lock has a hinged jack enclosure that encompasses a trailer jack. In a first restraining position the jack enclosure prevents a trailer jack from retracting to an transport position. In a second releasing position the jack lock may be easily and quickly removed from the jack. To further deter theft, a tongue arm is unitarily fabricated with and extends from the jack enclosure. The tongue arm runs under a trailer ball receiver, and terminates with a hitch stop that wraps around the ball receiver to block a land vehicle from accessing the trailer coupler. A lock selectively holds the jack enclosure closed to prevent the trailer jack from retracting, but when unlocked permits the jack enclosure to be removed from the trailer jack. Removal of the jack enclosure will also remove the hitch stop from blocking the ball receiver. A lock enclosure prevents access to the locking mechanisms.
