Support bridges for air diffusers including spring loading for air flow control blades

摘要

A slot diffuser includes a pair of elongate and parallel side walls spaced by pairs of bridges. The bridges include feet that slide along receivers in the side walls such that the bridges can be positioned at any location therealong and provide support to the bridges and stability to the diffuser. The bridges include slots that extend between the side rails and that receive ends of air flow control blades. The air flow control blades include an elongate planar portion supported by slot following pegs extending outwardly on either side of the planar portions to support the blades in the slots. The bridges include a spring mechanism to provide bias to the blades to prevent wedging and rattling. The bridges also include a top arcuate cover that reduces air drag and noise.
