Abstract
A casement window operator includes a linear input mechanism configured to be mounted to a stationary frame of a casement window, a linear to rotary motion converter operably coupled to an output of the linear input mechanism, a gear reducer operably coupled to an output of the rotary motion converter, and a sash arm operably coupled to an output of the gear reducer to rotate in conjunction with the output of the gear reducer. The sash arm is configured to extend from the stationary frame of the casement window to a rotatable window sash of the casement window.

A method of operating a casement window, the method comprising sliding a linear input mechanism mounted to a stationary frame of the casement window, wherein the casement window includes:
- the stationary frame;
- a rotatable window sash pivotably connected to the stationary frame;
- and
- a casement window operator, the casement window operator including:
- the linear input mechanism mounted to the stationary frame;
- a linear to rotary motion converter operably coupled to an output of the linear input mechanism;
- a gear reducer operably coupled to an output of the rotary motion converter;
- and
- an sash arm operably coupled to an output of the gear reducer to rotate in conjunction with the output of the gear reducer,
- wherein a distal end of the sash arm is connected to the rotatable window sash such that rotation of the sash arm drives pivoting of the rotatable window sash relative to the stationary frame in response to the sliding of the linear input mechanism.
