Abstract
A locking apparatus includes a fixed housing with a longitudinal elongated bore between two open ends. One end defines an arcuate track with a new rotational displacement range. A pivoting riser extends from a driver to an elongated retainer moving across a locking core configured with a predefined rotational range. A follower on the driver travels within the track. The core and the driver may be connected and inserted via the same open end for rotation within the bore. When the locking core is unlocked and rotated with an operating key, the riser displaces the retainer to retain the core within the housing, while the follower continues to rotate within the track so that the rotational range of the core is changed to the new rotational displacement range. The apparatus may include the core. The apparatus may exclude the core to allow separate installation for combined rotation with the driver.
