A lockset mechanism (20, 120) is provided with a spindle subassembly (24, 124) having a spindle component (44, 128) particularly configured to fracture when an over-torque is applied thereto for uncoupling the handle subassembly (22, 122) from the latch bolt subassembly (26). A spring mechanism (64, 130) is operably disposed between the lockset housing (32, 164) and the spindle subassembly (24, 124) for urging the spindle subassembly (24, 124) including the fractured spindle component (44, 128) away from the handle subassembly (22, 122) to render the lockset mechanism (20, 120) inoperable thereby.
L'invention concerne un mécanisme de serrure (20, 120) doté d'un sous ensemble tige (24, 124) ayant un élément tige (44, 128) particulièrement conçu pour se casser lorsqu'on lui applique un serrage excessif pour déboîter le sous ensemble poignée (22, 122) du sous ensemble pêne demi-tour (26). Un mécanisme à ressort (64, 130) est monté fonctionnel entre le logement de la serrure (32, 164) et le sous ensemble tige (24, 124) pour expulser le sous ensemble tige (24, 124) comprenant l'élément tige cassé (44, 128) du sous ensemble poignée (22, 122), ce qui rend le mécanisme de serrure (20, 120) inopérant.
