ABSTRACT:
A window hinge assembly for mounting a window sash to a window frame including an elongated track mountable along an axis to the window frame and a generally planar sash arm mountable along an axis to the window sash. The sash arm is also mounted for movement in a plane parallel to the track axis and has one end positionable adjacent one track end when the window sash is closed. A pair of mirror image hat members are interchangeably attachable separately to the arm one end and the track one end, where each of the hat members have a base selectively securable to the arm and the track and a perpendicularly bent edge on one end. The hat member bases are trapezoidal and attached to the arm and track so that the outwardly facing base side is shorter than the parallel opposite base side, with the bent edge protruding perpendicularly from the base.
