  • Patent number: 8783716
    Abstract: An improved pivot foot for a trailer jack of the type having a housing and a telescoping member that can be raised and lowered in and out of the housing eliminates the need for use of blocks between the jack and ground surface. The pivot foot includes a base and a pair of opposite sidewalls upstanding from the base. Each of the sidewalls has a cam slot and an ear slot formed in it. A bridge tab extends between the sidewalls for supporting the jack. A bore extends through the telescoping member of the jack. A pivot ring is provided, and it has a pair of outwardly extending ears. The pivot ring is sized to move freely along the length of the telescoping member. A cam pin extends transversely through the bore of the telescoping member and connects the sidewalls and the jack. The shaft of the cam pin travels within the cam slots to lift and rotate the foot assembly at a pivot defined by the ears of the pivot ring when the telescoping member is raised into the housing of the jack.
