| titleOfInvention | Fire damper frames |
| abstract | A fire damper frame of folded one piece construction having a centrally open transverse cross section formed from a unitary blank having cooperable interlocking means adjacent opposite ends for rigidly securing the fire damper frame in folded condition. The blank, in unfolded form, has a main planar central web portion disposed between parallel, longitudinally extending side peripheral mounting regions of substantially double blank thickness, and a pair of longitudinally extending, spaced, parallel upstanding flanges disposed at substantially right angles from an inner surface of the main planar central web portion and terminating at longitudinally extending outer edges. Each flange includes longitudinally spaced relief regions defining separate flange sections, each relief region in one flange being in transverse alignment with a corresponding region in the other flange. Each relief region comprises a slit extending from the outer edge of its respective flange in an inward direction for substantially the entire outward extent of the flange, and a portion of at least one of the flange sections adjacent each slit is disposed transversely out of the general plane of the longitudinally extending flange. Adjacent flange sections of each respective flange overlap to form frame corners when the frame is folded through the relief regions transverse to the elongate dimension of the blank to form a substantially continuous peripherally extending channel. |
