ABSTRACT:
The present device is a movable-louver heating and cooling register. The register is designed to have the same overall dimensions of commercial registers available today. The heating and cooling register has movable louvers installed on pivots that are formed in the register body. Two control arms are used to pivot the groups of louvers. The control arms are mounted on diagonals from each other. Both control arms are attached to a central control shaft, which is designed to rotate about its central axis. Because the control arms are mounted on opposite sides on the diagonal, as the control shaft is rotated, it pulls the two control arms in opposite directions. This causes each set of louvers to move in opposite directions. The advantage of movable louvers is that they can be used with both heating and cooling cycles. To operate the louvers, the control shaft can be turned by hand. Alternatively, a bi-metallic strip, installed around the control shaft, can be used to turn the control shaft depending on the temperature of the air exiting the register.
