Motorized Floor Diffuser system
In combination with a raised floor access system, where the floor consists of an upper surface and a lower surface, a generally circular opening within said floor for receiving an air diffuser assembly in communication with an underfloor air distribution plenum,
an automatic and adjustable air diffuser assembly comprising:
a.) a generally circular hanging frame member having an annular body portion for seating within said floor opening, where said body portion is externally threaded, an outwardly directed flange to overlie said upper floor surface;
b.) a threaded retention ring for threadably engaging said externally threaded body portion to lie against said lower floor surface and fix said hanging frame member to said floor;
c.) a removable and open grill member for seating on said circular hanging member, said grill member mounting a downwardly extended post slidably receiving a floating damper retention basin, and a light weight compression spring about said post in contact with said retention basin; and,
d.) a suspended fixed frame member, comparably sized to said body portion, comprising a first annular ring for mounting to said body portion, and a motor support member spaced axially from said annular ring by plural hanger members, where said motor support member mounts a reversible motor for raising and lowering a plurality of push rods, and said push rods, in contact with said retention basin, act to raise and lower said retention basin, whereby to selectively position said retention basin within said fixed frame member to control airflow from said plenum through said grill member.
