LOCK ASSEMBLY HAVING SECURED SETSCREW CONFIGURATION TO PREVENT UNAUTHORIZED HANDLE REMOVAL

摘要

A lock assembly includes a coupling mechanism connected to a spindle assembly. The coupling mechanism has an outer sleeve having a longitudinal interior opening that extends along a first axis. An operator handle includes a proximal lock core opening and a distal shaft portion having an axial opening formed to receive the outer sleeve. The distal shaft portion and the outer sleeve form a through path oriented across the longitudinal interior opening of the outer sleeve. A portion of the through path of the outer sleeve is formed to receive a setscrew in a screw manner to fasten the operator handle to the outer sleeve. A key-type lock core has a tailpiece that is arranged in the longitudinal interior opening of the outer sleeve to close the through path and block an access to the setscrew via the through path and thus to prevent unauthorized removal of the operator handle.
