摘要： An improved electrically operated gate having a rectangular frame with a top horizontal rail, a bottom horizontal rail and vertical ends, a roller adjacent each end extending below the bottom rail by which the gate rolls from open to closed positions, the gate moving in a longitudinal vertical plane, a roller engaging the top rail to maintain the frame in a vertical plane, an inverted horizontal rack affixed to the frame on one side thereof adjacent the frame bottom, the rack having a series of equally spaced teeth, an electric motor drive means affixed at a stationary position adjacent the gate frame and having a pinion drive gear rotatably extending therefrom below the rack and in engagement with the rack teeth, and springs to resiliently urge the pinion gear upwardly into engagement with the rack teeth so that when the electric motor is energized the frame is longitudinally moved to open or close the gate.
