ABSTRACT:
A casement hinge is provided having a track mounted to a window frame, a sash arm mounted to a window sash and connected to a track pivot at one end, and a support arm pivotally connected to the sash arm at one end and having a track pivot at the other end. A block with a serrated surface defines one of the track pivots, and a rack secured to the track includes cooperating serrated surfaces for fixing the block to a selected position on the track. The rack and the block include cooperating surfaces allowing sag correction by wedging a tool between the cooperating surfaces. A tab and slot interconnection for centering the block relative to the rack during installation is provided where the tab is breakable from the member to which it is fixed when correcting sag. The track is formed with a longitudinal section mounted to the window frame, the longitudinal section having a guide portion on which a shoe slides and a mounting portion spaced from the window frame so as to be offset from the guide portion. The track further includes an upright section along one side of the longitudinal section and extending away from the window frame, an overhanging section supported on the upright section spaced from the longitudinal section, and a flange extending upright from the longitudinal section. The shoe defines the other of the track pivots and includes a guide member which slides along and between the longitudinal, upright, and overhanging sections and the track flange. The sash arm overlies the overhanging section when the window is closed.
