Flush lock actuator

Abstract

A lock for securing a window sash against a window frame, including a housing mountable on a face of the window frame, and a handle extending generally longitudinally between first and second ends and pivotable in the housing about an axis disposed substantially halfway between the handle ends and oriented substantially transverse to the handle longitudinal direction. The handle includes a pivot at each handle end, and a pivot link is pivotably securable on one end to a window locking mechanism and pivotably securable on its other end to a selected one of the handle pivots. The housing has a substantially planar first face which is substantially the entire surface of the handle visible in the housing opening when the handle is in the first position and is substantially co-planar with the housing first face when the handle is in the first position. A slide is selectively movable into a recess in one of the handle ends to block pivoting of the handle. Manual movement of the handle from the first position to the second position may be initiated by pushing the actuator first face at one end.
