Title:
空気駆動式回転窓
Document Type and Number:
Japanese Patent JP4237292
Kind Code:
B2
Abstract:
An air-driven rotating window assembly (10) mountable to one side of a viewing window (16). The rotating window (12) assembly faces toward the working or weather exposed area and slings off, by centrifugal force, any debris that contacts the rotating window (12) so as to maintain clear visibility through a portion of the viewing window over which the rotating window extends. The rotating window assembly (12) includes a support base (14) and a rotating window rotatably mounted to the support base. The rotating window has an annular frame (17) with propulsion passages (19) therein that receive a flow of pressurized gas substantially tangentially to the frame. The propulsion passages redirect the gas to generate a propulsive force on the frame to spin the rotating window relative to the support base. The gas exits the annular frame (17) through a restricted gap between the support base and the rotating window so as to form an air barrier that prevents debris from passing through the gap.
