  • Locking system for a double-hung window
    Patent number: 6139071
    Abstract: A double-hung window construction includes a window jamb and a pair of sashes slidably movable within the window jamb. A pivot member pivotally connects each sash to the window jamb such that the sash can tilt relative to the window jamb around the pivot member. A combined locking and tilting mechanism is attached to each sash. The mechanism is movable between a locked position preventing sliding or tilting of the window, an operative position permitting sliding of the sash and preventing tilting of the sash, and a tilting position which allows the tilting movement of the sash. Each locking and tilting mechanism is independent of the operation of the remaining locking and tilting mechanism.
