Document Type and Number:
Japanese Patent JP2003526749
Kind Code:
A
Abstract:
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.
