ABSTRACT:
An operator for a jalousie window includes a linkage with two toggle joints. The toggle joints assist in locking the window in its fully opened or fully closed position. The toggle joints of the operator are actuated by an actuating lever which is mounted to the window frame of the jalousie window so as to provide a mechanical advantage to operation of the jalousie window. The mechanical advantage afforded by the operator allows relatively heavy jalousie window louvers and associated moving components to be actuated by means of a tolerable range of actuating forces. The operating linkage is equipped with brakes which permit the louvers of the window to be maintained in any number of fixed orientations between the fully opened and fully closed position of the window.
