Abstract
The rotatable louver holder disclosed comprises a toothed gear having a hub and arranged for axial rotation about a vertical axis and a plastic hanger member having a hook at the bottom for engaging in an opening of a louver. The hanger extends upwardly through the opening in the hub of the gear and has lateral projections engaged in diametrically opposite low points on the upper edge (guiding surface) of the hub. External force applied to the louver causes rotation of the hanger relative to the hub as the projections ride up the guiding surface toward diametrically opposite high points thereon. Stops on the hub and on the hanger limit the rotational movement; however, if a predetermined excessive amount of force is applied to the louver, the stops on the hanger are resilient enough to permit them to ride past the stops on the hole. After removal of external force applied to the louver, the projections return to the low point of the guiding surface under the influence of gravity.
