Lock and method of adjusting a lock configuration

A lock, comprising:

• a housing including an aperture;
• a lock cylinder configured to cover the aperture of the housing;
• and
• lock componentry positioned within the housing and being adjustable to alter a configuration of the lock;
• wherein the lock cylinder is removable from the housing to expose the aperture to provide access to the lock componentry in the housing such that the lock componentry is adjusted to set the configuration of the lock;
• wherein the lock componentry comprises two locking bars that are adjustable to set the configuration of the lock;
• and
• wherein the lock componentry comprises a locking bar selector that is accessible via the aperture of the housing and reversibly movable to:
• overlap the locking bars wherein the locking bars can only move together;
• or
• not overlap the locking bars wherein the locking bars are able to move independently of one another.

A lock, comprising:

• a housing including an aperture;
• a lock cylinder configured to cover the aperture of the housing;
• lock componentry positioned within the housing and being adjustable to alter a configuration of the lock;
• latch means movable between a forward position and a retracted position;
• a pair of actuators;
• a pair of locking bars;
• and
• moving means for moving the locking bars;
• wherein each actuator is movable to cause the latch means to move between its forward and retracted positions;
• wherein the moving means can, in at least one setting of the lock, cause movement of one of the locking bars independent of the other of the locking bars to engage a respective one of the actuators to prevent that respective actuator from moving the latch means between the forward and retracted positions;
• and
• wherein the lock cylinder is removable from the housing to expose the aperture to provide access to the lock componentry in the housing such that the lock componentry may be adjusted.

A method of adjusting a configuration of a lock, comprising:

• removing a lock cylinder covering an aperture in a lock housing to expose the aperture and provide access to lock componentry positioned within the lock housing, the lock componentry comprises two locking bars;
• adjusting the lock componentry in the lock housing by inserting a tool through the aperture previously covered by the lock cylinder to permit alteration of a configuration of the lock, wherein the adjusting comprises adjusting the two locking bars via engagement of the tool to set the configuration of the lock;
• setting the configuration of the lock by hand adjusting the lock componentry via the tool extending through the aperture;
• and
• reinserting the lock cylinder in the lock housing.

A method of adjusting a configuration of a lock, comprising:

• removing a lock cylinder covering an aperture in a lock housing to expose the aperture and provide access to lock componentry positioned within the lock housing;
• adjusting the lock componentry in the lock housing via access provided by the aperture to permit alteration of a configuration of the lock;
• setting the configuration of the lock via the adjusting of the lock componentry;
• and
• reinserting the lock cylinder in the lock housing;
• wherein the lock componentry comprises two locking bars;
• wherein the adjusting comprises adjusting the two locking bars to set the configuration of the lock;
• and
• wherein the two locking bars are set via the aperture in the lock housing to engage with a respective rotating actuator, and wherein the respective rotating actuator is turned as a result of a turn of a door handle engaged with the lock.
