Abstract

A lock for a door including a configurable lock function. The lock includes a removable and user accessible actuator which when removed from the lock disables a lock function, and when inserted into the lock enables the lock function. Removal of the actuator places the lock in a disabled condition in which the lock cannot be locked by other means. Insertion of the actuator into the lock places the lock in an enabled condition in which the lock is locked or unlocked by the position of the actuator. The lock is installed without the actuator when the lock is intended to be used only in a passage operation where the door provides access only, but does not restrict access. The lock is installed with the actuator when the lock is intended to be used in a privacy operation where the lock is intended to restrict access to an area.

First claim

1 .- 23 . (canceled)

24 . A door lock, comprising:
a latch mechanism comprising a latchbolt; an outside chassis engaged with the latch mechanism; an inside chassis engaged with the latch mechanism; a locking module, the locking module comprising a locking member operable to selectively provide the outside chassis with a locked state and to selectively provide the outside chassis with an unlocked state, wherein in the locked state the outside chassis is prevented from retracting the latchbolt, and wherein in the unlocked state the outside chassis is capable of retracting the latchbolt; and a removable actuator operable to engage the locking module, the actuator having an engaged condition in which the actuator is engaged with the locking module such that the locking member can selectively provide the outside chassis with the locked state and the unlocked state, the actuator having a disengaged condition in which the actuator is removed from the locking module and outside chassis remains in the unlocked state.

25 . The door lock of claim 24 , wherein the locking member has a locking position in which the locking member provides the outside chassis with the locked state;
wherein the locking member has an unlocking position in which the locking member provides the outside chassis with the unlocked state; wherein the locking module has a first configuration in which the actuator is in the engaged condition and is operable to selectively move the locking member between the locking position and the unlocking position; wherein the locking module has a second configuration in which the actuator is in the disengaged condition and the locking module maintains the locking member in the unlocking position; and wherein the locking module is configured to transition between the first configuration and the second configuration in response to movement of the actuator between the engaged condition and the disengaged condition.

26 . The door lock of claim 25 , wherein the locking module is operable to transition between the first configuration and the second configuration while the door lock is installed to a door.

27 . The door lock of claim 25 , wherein with the locking module in the first configuration and the actuator in the engaged condition;
wherein the actuator is operable to move between a first position and a second position; and wherein the locking member is configured to move between the locking position and the unlocking position as a result of movement of the actuator between the first position and the second position, the locking member having the unlocking position as a result of the actuator having the first position, and the locking member having the locking position as a result of the actuator having the second position.

28 . The door lock of claim 27 , wherein the locking module has a third configuration in which the actuator is in a partially-engaged condition; and
wherein with the locking module in the third configuration and the actuator in the partially-engaged condition, the locking mechanism is configured to retain the actuator in the first position, thereby preventing the actuator from moving the locking member into engagement with the outside chassis.

29 . The door lock of claim 25 , wherein the locking module comprises a blocking member operably connected with the locking member;
wherein the locking member is configured to move between the locking position and the unlocking position in response to axial movement of the blocking member; wherein the blocking member has an unblocking position in which axial movement of the blocking member is enabled, the blocking member having the unblocking position when the locking module is in the first configuration; and wherein the blocking member has a blocking position in which axial movement of the blocking member is prevented, the blocking member having the blocking position when the locking module is in the second configuration.

30 . The door lock of claim 29 , wherein the actuator, when engaged with the blocking member, is operable to rotate the blocking member between the blocking position and the unblocking position.

31 . The door lock of claim 29 , wherein the inside chassis comprises an inside rose having an opening, and wherein the blocking member is aligned with the opening such that the actuator is operable to engage the blocking member when inserted in the opening.

32 . The door lock of claim 24 , wherein the inside chassis includes an inside rose, the inside rose including an opening through which the actuator extends when the actuator is in the engaged condition.

33 . The door lock of claim 24 , wherein the locking module comprises a first locking module portion engaged with the outside chassis and a second locking module portion engaged with the inside chassis;
wherein the actuator is removably engaged with the second locking module portion; and wherein the locking member is coupled to the first locking module portion.

34 . A method of converting a configurable lockset between a first mode and a second mode, the method comprising:
installing a lockset to a door in one of the first mode or the second mode, the lockset comprising:
a latchbolt;
an outside chassis assembly engaged with the latchbolt;
an inside chassis assembly engaged with the latchbolt;
a lock mechanism engaged with each of the outside chassis assembly and the inside chassis assembly, the lock mechanism comprising a locking member having a locking position and an unlocking position, the lock mechanism having a locked state in which the locking member is in the locking position and prevents the outside chassis assembly from retracting the latchbolt, the lock mechanism having an unlocked state in which the locking member is in the unlocking position and the outside chassis assembly is capable of retracting the latchbolt; and
an actuator having an engaged state in which the actuator is engaged with the lock mechanism and a disengaged state in which the actuator is disengaged from the lock mechanism;
wherein the lock mechanism has a first configuration in the first mode of the lockset, and wherein with the lock mechanism in the first configuration, the actuator is in the engaged state and is operable to move the locking member between the locking position and the unlocking position such that the lock mechanism is operable to transition the lock mechanism between the locked state and the unlocked state; and
wherein the lock mechanism has a second configuration in the second mode of the lockset, and wherein with the lock mechanism in the second configuration, the actuator is in the disengaged condition and the locking member is retained in the unlocking position such that the lock mechanism is retained in the unlocked state; and
converting the lockset from the one of the first mode or the second mode to the other of the first mode or the second mode; wherein the converting the lockset from the second mode to the first mode comprises moving the actuator from the disengaged condition to the engaged condition, thereby transitioning the lock mechanism from the second configuration to the first configuration; and wherein the converting the lockset from the first mode to the second mode comprises moving the actuator from the engaged condition to the disengaged condition, thereby transitioning the lock mechanism from the first configuration to the second configuration.

35 . The method of claim 34 , wherein the inside chassis comprises an opening; wherein the lock mechanism comprises a blocking member aligned with the opening;
wherein the locking member is configured to move between the locking position a
