Claim 1
Independent Claim
292 words
A louver panel assembly for installation in a partition comprising a louver panel having louver blades therein; a first frame member; a second frame member; said first and second frame members having respective parallel elongated base portions with interengaging serrations for adjustably securing the first and second frame members together; a first pair of opposed retainer flange sections of the respective first and second frame members extending substantially normal to the base portions inward for extending over an edge of the louver panel; said first pair of opposed retainer flange sections being positioned a first distance apart for a given degree of interengagement of the frame members; a second pair of opposed retainer flange sections of the respective first and second frame members extending outward from the base portions for extending over the partition; said second pair of opposed retainer flange sections being positioned a second distance apart for the given degree of interengagement of the frame members and being substantially greater in width than the first pair of opposed retainer flange sections; said interengaging serrations providing adjustment between the first and second frame members to secure different thicknesses of louver panels between the opposing faces of the first pair of retainer flange sections; said second pair of opposed retainer flange sections being flexible and being curved inward at their distal edges toward each other such as to allow substantial flexing of the distal edges to accommodate for different thicknesses of partitions and to accommodate for different adjustments of the interengaging serrations; and said first and second distances being selected such that during installation both distal edges of the second pair of opposed flange sections will contact the partition before both of the first pair of retainer sections contact the louver panel.

Claim 3
Dependent Claim
26 words
The invention of claim 1 wherein the louver panel and frame members are rectangular with the frame members enclosing the periphery of the louver panel therebetween.
Claim 4
Dependent Claim
30 words
The invention of claim 1 wherein one of the frame members includes a backing member extending parallel to the base member to form a receiver cavity having the serrations therein.
Claim 5
Dependent Claim
26 words
The invention of claim 1 wherein the louver panel has a lesser thickness than the partition, and said first distance is less than said second distance.
Claim 6
Dependent Claim
82 words
The invention of claim 3 including corner bracket means and wherein said backing member includes an offset extremity to facilitate insertion of the base member of the other frame member into the receiver cavity, and wherein each first and second frame member is provided with slot means formed by lugs in the inside corner between the pair of second retaining flange sections and the respective backing member and base portion whereby adjacent frame members may be interlocked by the corner bracket means.
