Friction hinge for push-out style window
Abstract:
A push-out style window assembly including window hardware for frictionally retaining an open position of the window under typical loading conditions. A push-out style window assembly generally includes a friction hinge assembly including a track, a sash arm, a support arm, and a friction arm. The friction arm can include an adjustable and/or detachable slide enabling adjustment of a frictional resistance between the friction slider and the support arm. Using the friction arm, frictional resistance is provided so as to provide control both during opening of the window and in retaining the position of an open window.
