Abstract: A floor cable management system, which may simulate an in floor diffuser unit, that includes a below floor electrical receptacle having a top circular opening, and an above floor level circular housing for removably mounting to and over the circular opening. The above floor level circular housing includes a hinged cover member, which in turn mounts plural hinged access doors to allow feeding selected wires, cables and power cords to the below floor electrical receptacle, where the access doors may be locked to protect the fed items against damage.

Abstract: An automated and adjustable air diffuser mechanism for placement in a floor opening in a raised access flooring system having an air distribution plenum under the floor. The mechanism comprises a first, fixed circular hanging frame member, and a second, movable, generally circular dust trap member concentric with the first hanging frame member. The second member is movable relative to the first member to adjust the free area of the air passages located along the circumference of the first and second members, whereby to vary the airflow delivery from the distribution plenum to the room area above the mechanism.

Abstract: An automated and adjustable air diffuser assembly for placement in a floor opening in a raised access flooring system having an air distribution plenum under the floor. The assembly comprises a fixed circular hanging frame member, a suspendable fixed frame member secured thereto, a removable grill member mounting a floating debris/liquid retention basin, and an electric motor operating a plurality of push rods to raise and lower the retention basin.

Abstract: An air diffuser assembly for use in combination with an underfloor air distribution system, where the system includes in part a cavity under a floor, having an upper surface, transmitting air under pressure to selected locations above the floor. The air diffuser assembly comprises first and second annular rings threadably engaging one another and secured respectively to above and below the floor, where the first annular ring includes an annular shoulder for receiving a grill assembly. The grill assembly is seated on the shoulder and is in communication with the space above the upper surface. The grill assembly further includes a centrally disposed, downwardly extending, vertically adjustable rod mounting a circular basket at its free end. The basket includes an array of through holes for delivering pressurized air from the underfloor cavity to the diffuser assembly, and means, such as a rod, connecting the basket to the grill assembly to prevent rotation of the basket.
