ABSTRACT:
A window hinge having a track mountable to a window frame, a sash arm mountable to a window sash, and a plurality of pivotally interconnected links connecting the track to the sash arm to allow pivotal movement of the sash relative to the window frame. At least one of the links is pivotally connected to a shoe movable on the track and another of the links is pivotally connected to a block. The block includes a projecting stud and is elastically deformable to allow sliding of the block in the track with the stud retracted until snappingly securing the stud in a mounting slot in the track during field assembly. The hinge is mounted by first fixing the track to a window frame and the sash arm to a window sash, thereafter sliding the shoe and the block in the track to dispose the block stud adjacent the track slot, then fixing the block to the track with the block stud in the track slot.
