ABSTRACT:
A window hinge for mounting a window sash for pivotal movement between open and closed positions including a track mountable to window frame and a sash arm mountable to a window sash. The sash arm is supported for movement relative to the track by a plurality of links, with pivotal connections to the sash arm and to either the track or a shoe movable along the track. A cam surface on the sash arm coacts with a cam member on the track to assure pull-in of the sash arm when the window hinge moves to window-closed position. The cam surface has an apex which is offset relative to the center line of the sash arm and a pivot connection of a link to the sash arm is similarly offset whereby an inside edge of the sash arm is caused to align with an inside edge of the track when the window hinge is in window-closed position.
