Abstract:
1. A handle mechanism for use with a damper actuator system having a damper blade configured to be positioned within a duct of a duct system, a shaft in communication with the damper blade, and a driven gear operatively coupled to the shaft, the handle mechanism comprising: a drive gear configurable to be operatively coupled to the driven gear and for rotating the driven gear of the damper actuator system; a handle configured to rotate the drive gear, the handle has a first surface and an opposing second surface on an opposite side of the handle; a housing at least partially enclosing the drive gear, the housing defining an interior surface and an exterior surface; and a spring configured to bias the drive gear toward a first axial position relative to the housing; and wherein: the first surface of the handle is configured to be adjacent the exterior surface of the housing when the handle is in a first handle position, and the opposing second surface of the handle is configured to be adjacent the exterior surface of the housing when the handle is in a second handle position; and applying a force to the handle toward the housing when the handle is in the second position moves the drive gear against the bias of the spring and in an axial direction from the first axial position toward the handle and to a second axial position relative to the housing along an axis that extends through the drive gear.
