Gate assembly

摘要

A gate assembly for a motor driven vertically pivoting gate includes a support frame and coil springs attached between the gate and the support frame to bias the gate toward a vertical, open position and thereby assist the drive motor. A member secured to the support frame deflects the springs when the gate is in the open position, thereby placing the springs in tension so that the springs also assist the drive motor in starting the gate to move from its open position toward its closed position. The member also engages the gate when it is in its open position and supports the gate in a precisely vertical orientation.
