Abstract
Abstract A diffuser for conditioned air has interconnected frames, each frame supporting adjustable fin and damper units and separate adjustable fins. Each fin and damper unit has a pair of dampers as one component, a fin as another component, and a pivot. The two components include interfitting portions that enable the dampers and fin to be separately pivoted. One component has pivot-fitting and confining surfaces, at least when the two components are interconnected. The interconnecting portions permit of unit assembly only on relative movement between them in a direction lengthwise of the axis the pivot-confining surfaces define. The frames are formed from mitered lengths of extruded stock having a lengthwise channel with means dividing the channels into spaced, pivot-receiving sockets and with the channels facilitating the interconnection of the mitered ends.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
85 words
A damper-fin assembly for an air diffuser, said assembly comprising a frame including top, bottom and side members that are extrusions and means interconnecting said members, said top and bottom members having a channel extending lengthwise thereof with the channels opening towards each other, a series of damper units, fin units and pivots having ends, the ends of the pivots being removably received in said channels, and discontinuous means in said channels providing spaced sockets holding said pivot ends against movement lengthwise of said channels.
Claim 2
Dependent Claim
85 words
A damper-fin assembly for an air diffuser, said assembly comprising a frame including top, bottom and side members that are extrusions and means interconnecting said members, said top and bottom members having a channel extending lengthwise thereof with the channels opening towards each other, a series of damper units, fin units and pivots having ends, the ends of the pivots being removably received in said channels, and discontinuous means in said channels providing spaced sockets holding said pivot ends against movement lengthwise of said channels.
Claim 3
Dependent Claim
57 words
The damper-fin assembly of claim 1 in which the sockets of the chaNnels of the top and bottom frame members include a plurality of pairs of transverse deformations with the deformations of each pair defining with the included channel sides one of said sockets and corresponding sockets of the top and bottom frame members being vertically disposed.
Claim 4
Dependent Claim
39 words
The damper-fin assembly of claim 1 in which the channels of the top and bottom frame members are undercut and the sockets comprise a series of spacers slidably confined in each channel, one pivot end confined between two spacers.
Claim 5
Dependent Claim
28 words
The damper-fin assembly of claim 1 in which narrow ribs border each channel and are engageable by bottom and top ends of the fin units and damper units.
Claim 6
Dependent Claim
82 words
The damper-fin assembly of claim 1 in which the side members of the frame also have said channels, the channels are arcuate and more than 180* in extent and the ends of the frame members are mitered to provide corners, one mitered end at each such corner having a hole in its channel, and a screw extends through each such hole and is dimensioned to be threaded into the end of the channel of the other mitered frame end of that corner.
Claim 7
Dependent Claim
66 words
The damper-fin assembly of claim 5 in which the frame members having the holes in their mitered ends are the top and bottom frame members and their channels also include vertically aligned pairs of transverse deformations spaced lengthwise thereof with the deformations of each pair defining with the included channel sides a pivot-receiving socket, corresponding sockets of the top and bottom frame members being vertically aligned.
