  • Patent number: 10017019
    Abstract: 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.

    Abstract: A hitch accessory retaining device includes a pair of opposed engagement pins and a biasing device. When positioned within a shank body, the engagement pins are slidable within shank pinning apertures and are normally urged in outward, extended positions by the biasing device. When biased outwardly, a portion of each engagement pin extends outwardly from and projects beyond a shank sidewall while an additional portion of each engagement pin is retained within the shank body. A portion of the biasing device contacts, is attached to, or is part of, the engagement pins. The normally outwardly biased engagement pins are biasable inwardly to a retracted position within the shank pinning apertures to a position wherein the outward ends of the engagement pins are flush with the outward sides of shank sidewalls.

  • Publication number: 20150123379
    Abstract: A locking device for obstructing towing of a trailer has a lock base and a lock bracket. The lock base has an upright ball-shaped member and two legs each with an aperture. The lock bracket has two arms. When the locking device is in a locked condition, both arms are engaged in their corresponding apertures. When the locking device is in an unlocked condition, one arm of the lock bracket remains attached to its corresponding aperture, and the other arm is removed from the other aperture to release the coupler. Grooves on one of the arms allow a locking means to engage with the lock bracket at different height. In another aspect of the invention, the ball member is detachable and can be replaced by different sized ball member so that the same locking device can be used on trailer couplers with different socket sizes.

  • Publication number: 20150121975
    Abstract: A locking device for obstructing towing of an unattached trailer has a lock base and a single-armed curved interlock bracket. The lock base has a cylindrical leg. The single-armed interlock bracket has an grooved arm sliding along an aperture on the cylindrical leg and may be permanently attached to the lock base. Grooves on the arm allows a locking means to be engaged with the lock bracket at different height. When engaged, the locking means may restrict the interlock bracket from swirling. The open end of the interlock bracket provides flexibility to accommodate trailer couplers with different cap/rim sizes. The cylindrical leg may have a sealed bottom end and may function as a handle. The locking device may also feature a push-in locking mechanism to lock the interlock bracket in a position without using a key.
