Abstract
A motor-vehicle gate assembly for a driveway includes, in addition to the gate and an actuator for opening and closing the gate, a secondary barrier operable in response to operation of the gate to prevent motor-vehicle access to the gate when the latter is closed and to permit access to the gate when the latter is open. The barrier may be a flexible line which extends across the driveway and which is movable between a raised position above the driveway and a lowered position in a gutter in the surface of the driveway. Movement of the barrier between its raised and lower positions can be effected by a mechanical connection between the barrier and the gate.
