Abstract
As an air mover assembly is translated from a first orientation to a second orientation, a first roller and a second roller translate about at least one rail such that the a frame and a door maintain a position relative to the direction of the force of gravity.
Claims15
An air mover assembly comprising:
- an air mover;
- and
- a housing mechanically coupled to the air mover, the housing comprising an exhaust assembly comprising:
- a first roller having a first mass;
- a second roller having a second mass larger than the first mass;
- at least one generally arcuate rail for constraining motion of the first roller and the second roller within the at least one arcuate rail, wherein the at least one generally arcuate rail includes a first rail to constrain motion of the first roller and a second rail to constrain motion of the second roller, the first and second rails forming portions of a circumference of a circle;
- a generally circular frame rotatably coupled to the first roller and the second roller at an approximate circumference of the frame, such that the first roller and the second roller are located diametrically opposite of one another on the approximate circumference;
- and
- a door hingedly coupled to the frame and configured to assume a closed position under a force of gravity on the door in the absence of airflow generated by the air mover and configured to rotate from the closed position to an open position under a force of airflow from the air mover that overcomes the force of gravity on the door;
- wherein, as the air mover assembly is rotated from a first orientation to a second orientation, the first roller and the second roller are configured to move about the at least one rail such that the frame and the door maintain a position relative to a direction of the force of gravity.
