Door lock assembly

A lock assembly for use with a latch movable from an extended position to a retracted position, the lock assembly comprising:

• an interior handle manually operable to move the latch from the extended position to the retracted position;
• an interior locking actuator located on an exterior of the interior handle, the interior locking actuator manually movable from an unlocked position to a locked position;
• a biasing member that biases the interior locking actuator toward the unlocked position;
• a retaining member that retains the interior locking actuator in the locked position against the bias of the biasing member;
• an exterior handle;
• a driver rotatable from a locked position to an unlocked position such that the exterior handle is manually operable to retract the latch when the driver is in the unlocked position and the exterior handle is inoperable to retract the latch when the driver is in the locked position;
• and
• an interior spindle rotatable with the interior handle to move the latch from the extended position to the retracted position,
• wherein the interior locking actuator is manually pushed and manually rotated to move the locking actuator from the unlocked position to the locked position,
• wherein when the interior locking actuator is in the locked position, movement of the interior handle to retract the latch causes the biasing member to move the interior locking actuator toward the unlocked position,
• wherein the retaining member engages the interior locking actuator and the interior spindle to retain the interior locking actuator in the locked position,
• wherein rotation of the interior handle disengages the retaining member from the interior locking actuator and the interior spindle to allow the biasing member to move the interior locking actuator toward the unlocked position,
• wherein the interior spindle includes an aperture, and
• wherein the retaining member extends into the aperture of the interior spindle to retain the interior locking actuator in the locked position.

• a biasing member that biases the interior locking actuator toward the unlocked position;
• a retaining member that retains the interior locking actuator in the locked position against the bias of the biasing member;
• an exterior handle;
• a driver rotatable from a locked position to an unlocked position such that the exterior handle is manually operable to retract the latch when the driver is in the unlocked position and the exterior handle is inoperable to retract the latch when the driver is in the locked position;
• and
• an interior spindle rotatable with the interior handle to move the latch from the extended position to the retracted position,
• wherein the interior locking actuator is manually pushed and manually rotated to move the locking actuator from the unlocked position to the locked position,
• wherein when the interior locking actuator is in the locked position, movement of the interior handle to retract the latch causes the biasing member to move the interior locking actuator toward the unlocked position,
• wherein the retaining member engages the interior locking actuator and the interior spindle to retain the interior locking actuator in the locked position,
• wherein rotation of the interior handle disengages the retaining member from the interior locking actuator and the interior spindle to allow the biasing member to move the interior locking actuator toward the unlocked position, and
• wherein the retaining member includes a tab and a biasing member that biases the tab into engagement with the interior spindle to retain the interior locking actuator in the locked position.

A lock assembly for use with a latch movable from an extended position to a retracted position, the lock assembly comprising:

• a driver rotatable from a locked position to an unlocked position;
• an exterior handle manually operable to move the latch from the extended position to the retracted position when the driver is in the unlocked position and inoperable to move the latch when the driver is in the locked position;
• an exterior locking actuator coupled to the driver, the exterior locking actuator operable to rotate the driver from the locked position toward the unlocked position;
• an interior handle manually operable to move the latch from the extended position to the retracted position;
• an interior locking actuator coupled for rotation with the driver and the interior locking actuator manually movable from an unlocked position to a locked position and operable to rotate the driver from the unlocked position to the locked position;
• a first biasing member that biases the interior locking actuator in a direction from the exterior handle toward the interior handle;
• a second biasing member that rotationally biases the interior locking actuator with respect to the interior handle toward the unlocked position;
• and
• a retaining member that retains the interior locking actuator in the locked position against the bias of the first biasing member and the bias of the second biasing member,
• wherein rotation of the driver from the locked position to the unlocked position by the exterior locking actuator disengages the retaining member such that the first biasing member moves the interior locking actuator in the direction from the exterior handle toward the interior handle and the second biasing member rotates the interior locking actuator to push and rotate the interior locking actuator from the locked position toward the unlocked position,
• wherein the first biasing member includes a spring, and
• wherein the second biasing member includes a spring.
