Abstract

A window lock assembly is provided for facilitated locking of a pane-carrying frame or sash in a closed position with respect to a window casement. The lock assembly comprises a handle unit in a recessed, substantially flush-mounted position on the casement and including a movable operator handle connected by a concealed rack or the like to at least one locking cam unit mounted on the casement at a remote position relative to the operator handle. The operator handle is accessible for manual movement to displace a locking cam of the cam unit into releasable locking engagement with a keeper mounted on the sash.
