US 4,693,174 A · Air deflecting means for use with air outlets defined in dropped ceiling constructions

Abstract

An air deflector is disclosed with adjustable brackets for suspending the deflecting shield at variable distances from an air vent positioned within a dropped ceiling. The suspension brackets include a hook for resilient flexible securement with respect to the inverted T-shaped support members of the dropped ceiling as well as a rod having a number of cross members positioned thereon extendable through slots defined in the air deflector for maintaining that deflector at variable distances from the vent defined in the dropped ceiling thereabove. A vane member is included which may be engageable with respect to another similarly configured vane member such as to be angularly oriented with respect to the upper surface of the deflecting shield to guide air outwardly therefrom away from wall or corner areas as desired. For this purpose grooves may be defined in the upper surface of the deflecting shield.

Dependent claims

For use with air outlets defined in dropped ceiling constructions having a framework of inverted T-shaped support members with ceiling panels suspended therebetween, a means for deflecting air being emitted from the air outlets comprising:

( a) a plurality of suspension bracket means including:
(1) a hook means at the upper end of each of said suspension bracket means being selectively securable with respect to said inverted T-shaped support members;
(2) a rod means at the lower end of each of said suspension bracket means and extending downwardly from said hook means;
(3) a plurality of laterally extending cross-member means along said rod means positioned in spaced relation vertically with respect to one another;
(b) deflecting shield means detachably secured with respect to said suspension bracket means and extending generally horizontally therebetween and spaced downwardly from the ceiling panels and air outlets defined therein to deflect air exiting from the air outlets outwardly therefrom for dispersal thereof, said deflecting shield means defining a plurality of slot means therein adapted to receive said rod means extending therethrough;
and
(c) plurality of cover cap means positioned extending over the lower portions of said rod means and the lower of said cross-member means which extend below said deflecting shield means.

4 more elements

( a) four suspension bracket means made of flexibly resilient plastic, each bracket means including:
(1) a hook means at the upper end of each of said suspension bracket means being selectively securable with respect to said inverted T-shaped support members, said hook means including a loop member at the uppermost end of said suspension bracket means which defines a cut section therein adapted to receive a portion of said inverted T-shaped support member extending therethrough to facilitate gripping thereof by said suspension bracket means;
(2) a rod means at the lower end of each of said suspension bracket means and extending downwardly from said hook means;
(3) a plurality of laterally extending cross-member means along said rod means positioned in spaced relation vertically with respect to one another;
(4) a frangible section defined on each of said rod means immediately below each of said laterally extending cross-members to facilitate severing of said rod means at these locations during installation;
( b) an approximately square deflecting shield means detachably secured with respect to said suspension bracket means and extending horizontally therebetween and spaced downwardly from the ceiling panels and air outlets defined therein to deflect air exiting from the air outlets outwardly therefrom for dispersal thereof, said deflecting shield means being made of similar material as the ceiling panels, said deflecting shield means defining four slot means therein each being adapted to receive one of said rod means extending therethrough with said laterally extending cross-member means being perpendicularly oriented with respect to said slot means;
and
(c) a plurality of hemispherically-shaped cover cap means positioned extending over the lower portions of said rod means and the lower of said cross-member means which extend below said deflecting shield means and being in abutment therewith, said cover cap means being made of a material denser than the material of which said deflecting shield means is made.
