Abstract
Abstract An air distribution ceiling for clean rooms is disclosed which includes a first or primary plenum chamber at the top of a room with a clean air supply communicating with it, the top of this chamber being bounded by the room ceiling and the bottom being bounded by a plurality of vertically spaced horizontal interlocked upper panels, a second plenum chamber bounded at the top by the upper panels and at the bottom by lower horizontal interlocked panels and forming the ceiling of the room. The panels are carried on spaced parallel supporting bars suspended from the top wall of the room and extending therealong, the supporting bars being held in spaced relation by spacer bars extending therebetween and having ledges to carry the upper and lower plates and to permit the insertion and removal of the lower panels from below. The panels each has a plurality of nozzle holes therethrough for downward air delivery and to provide for uniform air displacement within the room. The panels are formed of synthetic plastic material, the upper panels preferably being of transparent material and the lower panels being of translucent material, and can have strip fluorescent lights installed thereabove at the top of first chamber to illuminate the room.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
78 words
A support member for the panels of an air distribution system comprising a unitary elongated bar having an upper attaching rib, an upper horizontally extending portion below said rib with horizontal panel supporting faces therealong, a lower horizontally extending portion below said upper portion with horizontal panel supporting faces therealong, and a vertically disposed connecting portion between said horizontally extending portions and having a portion thereof offset to provide a clearance for insertion of the panels from below.
Claim 2
Dependent Claim
78 words
A support member for the panels of an air distribution system comprising a unitary elongated bar having an upper attaching rib, an upper horizontally extending portion below said rib with horizontal panel supporting faces therealong, a lower horizontally extending portion below said upper portion with horizontal panel supporting faces therealong, and a vertically disposed connecting portion between said horizontally extending portions and having a portion thereof offset to provide a clearance for insertion of the panels from below.
Claim 3
Dependent Claim
38 words
An air distribution system as defined in claim 1 in which each of said panels has a plurality of grooves on the upper face thereof, and said openings in said panels extend from bottom portions of said grooves.
Claim 4
Dependent Claim
24 words
An air distribution system as defined in claim 1 in which said offset portion extends from one edge of the upper horizontally extending portion.
Claim 5
Dependent Claim
135 words
An air distribution system for a room having a ceiling and side walls extending downwardly from the ceiling comprising a plurality of elongated spaced parallel support members spaced below said ceiling, spacer members in engagement with said support members at predetermined intervals along the lengths of said support members, each of said support members comprising a unitary bar having upper panel supporting portions extending along each side thereof, and spaced therebelow, lower panel supporting portions extending along each side thereof, said support members between said upper and lower panel supporting portions having transverse longitudinally extending offset portions permitting insertion of panels from below, and a plurality of panels at at least one level supported by opposite panel supporting portions of contiguous support members, said panels having a plurality of openings therethrough for downward air delivery.
Claim 6
Dependent Claim
135 words
An air distribution system for a room having a ceiling and side walls extending downwardly from the ceiling comprising a plurality of elongated spaced parallel support members spaced below said ceiling, spacer members in engagement with said support members at predetermined intervals along the lengths of said support members, each of said support members comprising a unitary bar having upper panel supporting portions extending along each side thereof, and spaced therebelow, lower panel supporting portions extending along each side thereof, said support members between said upper and lower panel supporting portions having transverse longitudinally extending offset portions permitting insertion of panels from below, and a plurality of panels at at least one level supported by opposite panel supporting portions of contiguous support members, said panels having a plurality of openings therethrough for downward air delivery.
Claim 7
Dependent Claim
72 words
An air distribution system as defined in claim 4 in which each of said upper and lower panel supporting portions of contiguous support members has upper and lower panels supported thereon, and each of said panels has a plurality of openings therethrough for downward air delivery therethrough, the space above said upper panels provides a primary plenum chamber and the space between said upper and lower panels providing a secondary plenum chamber.
Claim 8
Dependent Claim
32 words
An air distribution system as defined in claim 5 in which each of said panels has an end edge portion for overlapping engagement with an end edge portion of the next panel.
Claim 9
Dependent Claim
