A driver element in this lock has two outer surface sections. The first of the sections has a first geometrical cross-sectional configuration which engages an outer lever spindle in both the locked and unlocked condition. In the unlocked condition the first section also engages an outer driver spindle which rotates with the outer lever handle and outer lever spindle and engages the latch retraction structure for retraction of the latch. In the locked position, a push button on the inner handle pushes the driver such that a second section of the outer surface of the driver is aligned with the outer drive spindle and the second section is free of driving engagement with the outer driver spindle such that operation of the latch is prevented when the outer lever handle is rotated.

[ What is claimed:] [1.] A driver in a lock arrangement of the type having a rotatable outer lever, an outer lever spindle connected to the outer lever for rotation therewith, a latch, an outer drive spindle for selectively retracting the latch, the outer drive spindle selectively rotated with the outer lever and outer lever spindle, the driver comprising, in combination:a body member having a first axis and having a first end, a second end, and an external surface extending between said first end and said second end and having a locked position for the lock arrangement in a locked condition and an unlocked position for the lock arrangement in an unlocked condition;said external surface having:a first section having a first preselected geometrical configuration in regions adjacent said first end and said first section extending toward said second end, and said first section operatively engaging the outer lever spindle and rotated by the outer lever spindle and operatively engaging the outer drive spindle to engage and retract the latch for the lock in the unlocked condition;a second section intermediate said first section and said second end and having a second geometrical configuration and said second section free of operative driving engagement with the outer drive spindle for the lock in a locked condition; andsaid body member of said driver axially movable along said first axis between said locked and unlocked positions.
