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.
