In the closed position an edge of the adjacent blade abuts a blade stop surface formed along each end, such that in the closed position one edge of the blade adjacent to each end of the frame extends into a recess and abuts the blade stop surface, to prevent air from flowing between the blade and the end of the frame. In the preferred embodiments the blade stop surfaces are integrally formed in each end panel. | 04-28-2016 |

20100112931 | Combination bearing, linkage pin and shaft coupling for a damper - An HVAC damper includes a sheet metal frame surrounding a series of pivotal damper blades that are each supported by a pair of plastic bearing members. Each bearing member is a unitary piece that includes a radial bearing, a thrust bearing, a lug for connecting to a damper blade, a shaft-receiving feature for connecting to a drive shaft, and multiple crank pins for selectively connecting to a drive linkage. Choosing which crank pin gets connected to the linkage determines a damper blade's rotational direction relative to the other damper blades. Adjacent damper blades preferably rotate in opposite directions to ensure positive sealing engagement between their adjacent blade tips. The bearing members allow the drive linkage to be installed outside the frame to avoid obstructing the airflow through the damper. During assembly, the bearing members allow the damper blades to be placed within the frame prior to installing the bearing members. | 05-06-2010 |
