Abstract
A cylindrically shaped lock structure adapted to receive an associated rod-shaped key is disclosed. The lock comprises a rotor case having an annular rotor member disposed therein. The rotor member contains a plurality of slidable pin members radially extending into a central key opening in the rotor member. The key opening is arranged and configured to receive the associated rod key such that when the rod key is inserted, the pin members retract into the rotor case and selectively render the rotor movable therein. A latch actuating system is coupled to the rotor member via an arm member whereby rotation of the rotor member causes the actuating system to render a latch movable from its initially closed position to an open position.
