    摘要： A frame assembly supporting an overhead door has a horizontal header connected to upright columns or posts with splice assemblies. Fasteners mounted on the columns cooperate with retainers on the splice assemblies to position and connect the columns to the header. Hinges pivotally mount the door on the header for movement between open and closed positions. Linear actuators connected to the frame assembly and door are operable to move the door between door open and door closed positions.

    摘要： A bi-fold door is equipped with door lifting devices operated with a reversible electric motor drive to selectively open and close the door. The door lifting devices have winches operable to wind and unwind elongated webs connected at one end to rotatable members of the winches and anchored at the opposite end of the door. Anchors mounted on the door have adjustable sleeves operable to take up slack of the webs. The door moves at an increasing rate of speed from its closed to open positions and a decreasing rate of speed from its open to closed positions.

    摘要： An overhead door frame assembly has a horizontal header connected to tripod legs with splice assemblies. Each tripod leg has two upright columns connected to an upright I-bar. The splice assemblies connect the upright columns to the header. Hinges pivotally mount an overhead door to the header to allow hydraulic cylinders to move the overhead door to an open position and a closed position.
