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.
Claims20
A window assembly comprising:
- a frame defining an opening;
- a sash assembly receivable in the opening of the frame;
- at least one friction hinge operably coupling the sash assembly to the frame such that the sash assembly is selectively shiftable between a closed position in which the sash assembly is received in the frame to close the opening and an open position in which the sash assembly is disposed at an angle relative to the frame, the friction hinge comprising:
- a track on the frame;
- a slider slidable along the track;
- a sash arm on the sash, the sash arm pivotally coupled to the slider;
- a support arm pivotally coupled to the track and pivotally coupled to the sash arm;
- and
- a friction arm assembly including a friction arm pivotally coupled to the sash arm and a friction slider assembly pivotally coupled to the friction arm and slidable along the support arm, wherein the friction slider assembly frictionally engages the support arm to provide a biasing force resisting shifting of the sash assembly between the open position and the closed position.
A friction hinge for an operable window assembly, comprising;
- a track;
- a slider slidable along the track;
- a sash arm, the sash arm pivotally coupled to the slider;
- a support arm pivotally coupled to the track and pivotally coupled to the sash arm;
- and
- a friction arm assembly including a friction arm pivotally coupled to the sash arm and a friction slider assembly pivotally coupled to the friction arm and slidable along the support arm, wherein the friction slider assembly frictionally engages the support arm to provide a biasing force resisting sliding of the friction slider assembly on the support arm.
