Abstract
A window operator for repositioning a window sash within a window frame. The window operator includes a crank handle for rotating a shaft with a pinion gear. The pinion gear operably engages with a rack containing cutouts, the rack having oppositely disposed first and second ends. The rack is translatable within a track disposed within the window frame. The window operator also includes an operator arm connectable between a first end of the rack and the sash wherein rotation of the shaft by the handle imparts movement to the rack and the operator arm, the rack and operator arm movement capable of transitioning the sash between a window open and a window closed position.
Claims19
A casement operator for a window having a window frame and a sash operable between a window closed position in which the sash is received in the frame and a window open position in which the sash is swung outwardly from the frame, the casement operator comprising:
- a rack with a first end and a second end, the rack slidable in a track disposed within the window frame;
- an operator arm with a first end and a second end, the first end of the operator arm interchangeably and rotatably connectable to either the first end or the second end of the rack depending upon a desired swing direction of the sash, the second end of the operator arm rotatably connected to the sash;
- a shaft with a first end and a second end;
- and
- a pinion mounted to the shaft proximate the second end, wherein the pinion operably engages with the rack, and pinion rotation imparts movement to the rack and the operator arm, said rack and operator arm movement capable of transitioning the sash between the window open and the window closed position.
A window operator for a window having a window frame and a movable window sash, the window operator comprising:
- a rack with oppositely disposed first and second ends, the rack disposed within a track within the window frame, the rack being moveable within the track and the rack having a boss extending upwardly from each of the first and second ends;
- an operator arm with first and second ends, the operator arm connectable between a sash bracket at the second end, and the boss extending upwardly from the first end of the rack, the sash bracket in turn mounted to the window sash;
- a hinge arm rotationally mounted to a hinge shoe, wherein the hinge shoe is disposed upon a hinge track, wherein the hinge track comprises an overhanging flange forming a longitudinally extending channel, an upwardly extending flange on the hinge shoe is received into the longitudinally extending channel and slidably secured therein;
- a shaft with a first end and a second end;
- a handle mounted to the first end of the shaft;
- and
- a pinion mounted to the shaft proximate the second end, wherein the pinion operably engages with the rack, and rotation of the shaft by the handle imparts movement to the rack and the operator arm, said rack and operator arm movement capable of transitioning the sash between a window open and a window closed position.
