This invention relates to the automatic opening and closing of typical forced hot air registers deflector and cover. The usual and common practice of deflecting hot air as it leaves the register is to place a separate deflector on the register. These deflectors are meant to direct the hot air to the center of the room where it is most desired. The current available deflectors do not act as a cover and are inconvenient as they protrude above the floor and are therefore in a position to be easily displaced and broken. It is the purpose of this invention to prevent this occurrence by automatically closing the deflector almost flat with the floor and at the same time acting as a cover for the register preventing such things as dust, dirt, spilled liquids, dropped objects, insects, etc. from entering the hot air system. The heat from the hot air system causes the bimetallic spring to move, (either expand or contract), causing the actuating rod to push up the register deflector/cover. The bimetallic spring holds the deflector/cover in the fully opened position until the heat shuts down thereby causing the spring to rotate in the opposite direction and lowering the deflector/cover to the fully closed position.
