Abstract
A door lock having upper and lower vertically spaced actuator seats centered on respective vertically spaced upper and lower axes has a handle assembly having inner and outer mounting plates horizontally flanking the door lock. An upper stem fitted in the upper actuator seat and supported on the inner plate can rotate about the upper actuator axis and carries an inner handle. A lower stem fitted in the lower actuator seat and supported on the outer plate can rotate about the lower axis. An outer stem separate from the inner stem and supported on the outer plate can rotate about the upper axis coaxially with the inner stem and carries an outer handle. Gearing interconnects the outer and lower stems for rotation of the lower stem about the lower axis on rotation of the outer stem about the upper axis.
