Abstract
Patent 599205 An actuator assembly for use with a lock assembly of the kind having a housing and a bolt movable relative to the housing and the lock assembly to be located on a door with the actuator assembly, comprises a rotatable member 18 that is rotatable from one side of the door about a longitudinal axis XX, a tailbar 17 having a proximal portion 23 that interacts with the rotatable member 18 so as to rotate therewith and a distal portion that interacts with the lock assembly so that rotation of the tailbar 17 about the longitudinal axis XX can adjust a condition of the lock assembly. The rotatable member 18 has a control zone 22 which interacts with the proximal portion 23 of the tailbar 17 where the position of the tailbar 17 relative to the rotatable member 18 is adjustable in the longitudinal direction to allow for doors of different thickness. The assembly further has a retainer 11 that interacts with the rotatable member 18 and the tailbar 17 to retain the proximal portion 23 in the control zone 22 ongitudinal axis XX, a tailbar 17 having a proximal portion 23 that interacts with the rotatable member 18 so as to rotate therewith and a distal portion that interacts with the lock assembly so that rotation of the tailbar 17 about the longitudinal axis XX can adjust a condition of the lock assembly. The rotatable member 18 has a control zone 22 which interacts with the proximal portion 23 of the tailbar 17 where the position of the tailbar 17 relative to the rotatable member 18 is adjustable in the longitudinal direction to allow for doors of different thickness.

an edge of a door and will have a bolt that is movable relative to the
Door sides the panel
mortice lock cavity, furniture located on opposing of door
will often include an actuator assembly in the form of a handle and or turn knob
that is operable to move the bolt. The lock assembly will also include a lock
mechanism that controls the function of the lock assembly such as preventing
movement of the bolt or operation of the handle. The door furniture will include
a further actuator assembly in the form a turn knob or cylinder lock that

operable to adjust the condition of the lock mechanism,
The further actuator assembly can include a tailbar for connecting the knob,

thickness. One option is to tailbars in a range of lengths, or another
provide
option is to long tailbars that are cut down to size on site. Neither option
is particularly efficient. The first option requires the lock supplier/installer to
