Abstract
Abstract A system of rigid, generally planar dimensions adapted to by removably, hingeably coupled to a conventional ventilator louver assembly to environmentally seal same to prevent energy losses. The louver covering system includes a rigid, generally rectangular frame formed of specially extruded members, which frame surroundably supports a rigid, generally planar insulating sheet. The frame includes front, side, and rear extrusion members which include integral bosses to aid in assembly. A separate, rigid, elongated extruded hanging rail having a hinge portion is adapted to be permanently coupled to the louver assembly. The system frame rear includes a cooperating hinge portion, which, when coupled to the aforementioned hanging rail hinge coupling extrusion enables the system to be hingeably swung to a closed position relative to the louver assembly. Latching means, preferably coupled to the louver assembly, may be manually twisted to engage flange portions of the frame to seal the louver. Frame channels support a plurality of insulating strips which form a surrounding seal which minimize air currents otherwise associated with conventional louver assemblies.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
308 words
A removable energy saving covering system for selectively sealing conventional ventilation louver assemblies, the system comprising: a generally planar louver covering member adapted to be removably secured in generally horizontally oriented parallel relation with respect to a ventilation louver to be sealed, the covering member comprising a rigid, generally rectangular frame comprising: a rigid, elongated front extrusion member and a pair of parallel, spaced apart, elongated, rigid side extrusion members projecting perpendicularly from and coupled to said front extrusion member at opposite ends thereof; a rear, elongated, rigid extrusion member rigidly coupled between said side extrusion members in spaced-apart, parallel relation with respect to said front extrusion member and including an integral outwardly projecting, bottom arcuate lip member; a generally planar, rectangular sheet of insulating material secured by and enclosed between said frame extrusion members; said frame front, rear and side extrusion members being generally of C-shaped cross section and including: a rigid, generally planar top portion including channel means defined therein for mounting insulation strips adapted to form a seal around the periphery of said louver assembly; an integral, rigid side portion including inwardly extending, integral boss means for facilitating assembly of said frame; a lower, generally integral planar bottom generally parallel to said top and, in cooperation with said top, operative to to sandwich the edges of said sheet of insulating material therebetween; and, said front and side frame extrusion members including an integrally outwardly extending generally planar, peripheral flange; a rigid, generally L-shaped, elongated extruded hanging rail adapted to be permanently mounted adjacent said louver, said rail including a lower, arcuate lip portion adapted to be coupled to said rear frame member extrusion lip for hingeably mounting said covering member over said louver assembly; and, latch means for selectively securing said covering member in a closed, generally horizontal sealing position relative to said louver assembly.
Claim 2
Dependent Claim
308 words
A removable energy saving covering system for selectively sealing conventional ventilation louver assemblies, the system comprising: a generally planar louver covering member adapted to be removably secured in generally horizontally oriented parallel relation with respect to a ventilation louver to be sealed, the covering member comprising a rigid, generally rectangular frame comprising: a rigid, elongated front extrusion member and a pair of parallel, spaced apart, elongated, rigid side extrusion members projecting perpendicularly from and coupled to said front extrusion member at opposite ends thereof; a rear, elongated, rigid extrusion member rigidly coupled between said side extrusion members in spaced-apart, parallel relation with respect to said front extrusion member and including an integral outwardly projecting, bottom arcuate lip member; a generally planar, rectangular sheet of insulating material secured by and enclosed between said frame extrusion members; said frame front, rear and side extrusion members being generally of C-shaped cross section and including: a rigid, generally planar top portion including channel means defined therein for mounting insulation strips adapted to form a seal around the periphery of said louver assembly; an integral, rigid side portion including inwardly extending, integral boss means for facilitating assembly of said frame; a lower, generally integral planar bottom generally parallel to said top and, in cooperation with said top, operative to to sandwich the edges of said sheet of insulating material therebetween; and, said front and side frame extrusion members including an integrally outwardly extending generally planar, peripheral flange; a rigid, generally L-shaped, elongated extruded hanging rail adapted to be permanently mounted adjacent said louver, said rail including a lower, arcuate lip portion adapted to be coupled to said rear frame member extrusion lip for hingeably mounting said covering member over said louver assembly; and, latch means for selectively securing said covering member in a closed, generally horizontal sealing position relative to said louver assembly.
Claim 3
Dependent Claim
40 words
The combination as defined in claim 1 wherein said latch means is permanently coupled to a portion of said ventilation louver assembly and operative to engage at least a portion of the frame flange portion to operatively secure the system.
