1. A casement operator for a window having a window frame and a movable window sash and sash lock comprising:
- a base mounted to the window frame;
a deployment linkage connectable between the window frame and said base and operable to cause movement of the window sash;
a rotatable handle;
a gear drive interconnecting said handle and said deployment linkage;
a lock linkage coacting with said deployment linkage and sash lock and having a window-actuated trigger for activating said lock linkage, said lock linkage preventing forcing of the deployment linkage in the event that the window is forced when closed.

Abstract
A casement operator for a window has a deployment linkage connectable between the window frame and the base and operable to cause movement of the window sash. A gear drive drives the deployment linkage, which coacts with a sash lock and a lock linkage having a window-actuated trigger. A plurality of rigid links are in pivotal engagement with the deployment linkage and in driving engagement with the gear drive, and a tie rod is disposed intermediate the rigid links and the sash lock. A trip lever with a trigger extending beyond the window frame is pivotally secured to the base and engageable with the lock linkage for restricting the movement of said lock linkage during a non-locking mode of operation of the operator. The deployment linkage includes a first element pivotally supporting one end of the window sash, a slider track along the window frame, a support link fixedly pivoted to the window sash on one end and to a second element on the other end, and a drive linkage having one end engaging the window sash and the other end drivably connected to the gear drive. The deployment linkage has the first element slidable in the slider track, the second element fixed relative to the window frame, and one end of the drive linkage fixed to the window sash and including a pivot intermediate its ends.

10. The casement operator for a window having a window frame and a moveable window sash and sash lock comprising:
-
a base mounted to the window frame; a deployment linkage connectable between the window frame and said base and operable to cause movement of the window sash; a rotatable handle; a gear drive interconnecting said handle and said deployment linkage; and a lock linkage coacting with said deployment linkage and sash lock for activating said lock linkage, and lock linkage including a cam pivotally connected to said base and having an arcuate slot extending therethrough, a gear lever having a pin projecting therefrom and received int he arcuate slot of said cam for controlling relative rotation herebetween, said gear lever being in driving engagement with said rotatable handle, a motion-transmitting tie rod intermediate said cam and the sash lock, and a window actuated trigger pivotally secured to said base and engageable with said gear lever wherein during a non-locking mode of operation of said operator said trigger extends beyond the window frame with said movement of said gear lever.
