ABSTRACT:
A method of converting a conventional lock set from one manufacturer's lock cylinder to another's is provided. The method includes provision of a universal doorknob or handle mountable, generally by means of adaptors, on any of a variety of manufactures of hardware systems. The universal knob includes means therein for mounting of a selected manufacture or design of lock cylinder. According to the method a tail piece member is provided, to translate motion from the lock cylinder to a drive mechanism of the hardware system being converted. Generally, according to the method each different design of lock cylinder will have a different universal knob design associated therewith. Further, each selected lock cylinder design will have associated therewith a set of tail piece members, one for each manufacture or design of hardware systems. As a result of the above, almost any type of hardware system can be readily converted to a system utilizing a universal knob and a selected lock cylinder.
