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.
Claims8
A lock structure and associated rod key comprising:
- a cylinder lock comprising:
- a. a rotor case;
- b. a rotatable, pin-retaining rotor member disposed in said case, said rotor member having a key way configured to receive said rod key and a plurality of holes being radially disposed in said rotor member and extending outwardly;
- c. pin members slideably disposed in said holes and;
- d. a slideable locking plate coupled to a cam member, said plate and cam member disposed in said lock such that rotation of said rotor causes an activator coupled to said rotor to engage said cam member and thereby to remove said locking plate into a retracted position;
- a rod key comprising:
- e. a stick having at least eight sides;
- and
- f. at least two different key patterns provided in alternate sides of said stick, said key patterns being arranged and configured such that they correspond with pin members of at least two different cylinder locks whereby said single rod key may unlock at least two locks with different pin member distributions.
A lock having a slideable latch member and being activated by an associated rod key comprising:
- a. a rotor case having an annular rotor member disposed therein, said rotor member containing a plurality of slideable pin members radially extending into a central key way, said pin members disposed in said rotors such that insertion of said associated rod key having at least two key patterns formed in alternate sides of said rod key causes said pin members to engage with a particular one of said key patterns and to move into a retracted position, when in said retracted position, said rotor member is rendered rotatable, whereby said single rod key may unlock at least two locks with different pin member distrubution;
- and
- b. a latch actuating assembly, said assembly being coupled to said rotor and to said latch whereby rotation of said associated key causes said latch to be movable into an open position.
