ABSTRACT:
A remotely controlled powered hingeless ventilator has a cover configured on a frame on a side thereof opposite from a tension rod. The cover is variably positionable between a closed position and a fully open position relative to the frame. An actuating member connected to an underside of the cover extends through a slot in a plate member across the ventilation opening and includes an arcuate guide slot defined therein. The tension rod is disposed through this guide slot. A motor is mounted on the frame and is connectable to a power source. The motor includes a rotatable drive arm connected to the actuating member. The drive arm has a generally arcuate shape and is connected to the actuating member so that an opening and closing force is exerted by the drive arm to the actuating member along a line of force corresponding generally to an extension of the arcuate guide slot.
