Abstract
A window assembly comprises an open rectangular frame which, in use, is fixed, and a rectangular vent which is movable into and out of engagement with the open frame. The vent is connected to the open frame by a plurality of extensible friction linkages so arranged that the vent may be selectively adjusted angularly with respect to the frame by differential extension of at least certain of the linkages.
