Abstract: A hinge assembly for a casement window including a track having a cam engaging portion defining a tri-lobular aperture, a sash arm pivotably and slidably coupled to the track, and a support arm pivotably coupled to the track on a first end and to the sash arm at the opposing end. An adjustable cam is operably connected through the support arm to engage the non-circular aperture within the track such that rotation of the adjustable cam selectively shifts the position of the support arm relative to the track to alleviate sash sag.

Abstract: A window fastener for controlling the locking and unlocking of a window is disclosed. The fastener provides an unlocking feature that is manually activated by the user and a locking feature that is automatically activated as the window is moved substantially proximate to the closed position. The unlocking feature disengages the fastener from the window and maintains disengagement so that further manipulation of the fastener is not required to facilitate window opening. The fastener also provides a positive confirmation feature that informs the user that the window is either closed and locked or open and unlocked.
