Abstract
A lock assembly incorporating a number of features designed to defeat attempts to pick or destroy the lock. The lock cylinder assembly employs multiple arrays of pass key pins, making picking of the lock much more difficult. Second, the arrangement of the pass key pins in separate arrays requires that multiple cuts would have to be made into the lock housing mogul or cylinder blank in order to defeat the lock cylinder assembly. Third, the lock cylinder assembly of the present invention may incorporate multiple sets of hardened dowel pins to prevent drilling through the lock housing mogul in the area of the driver pins. Fourth, the lock cylinder assembly of the present invention may incorporate a hardened cylinder shield behind the front face of the cylinder blank to prevent drilling through the cylinder blank.
Claims17
A lock assembly comprising:
- a cover assembly having a front surface;
- a cam having a generally-cylindrical body with at least one connection feature disposed on the end thereof and having a lobe protruding radially from the body, disposed within the cover assembly in such manner that the lobe is free to rotate within a limited envelope of rotary motion;
- a lockbolt disposed within the cover assembly having a pocket disposed therein, the pocket being oriented so that the lobe of the cam interacts with an inside surface of the pocket;
- a lock housing mogul assembly, disposed in the front surface of the cover assembly, and operably connected to the connection feature on the end of the cam, wherein the cam is disposed within a cam retainer having a slot therein and the cam lobe interacts with the lockbolt though the slot.
A lock assembly comprising:
- a cover assembly having a front surface and a rear surface;
- a cam having a generally-cylindrical body with at least one connection feature disposed on each end thereof and having a lobe protruding radially from the body, disposed within the cover assembly in such manner that the lobe is free to rotate within a limited envelope of rotary motion;
- a lockbolt disposed within the cover assembly having a pocket disposed therein, the pocket being oriented so that the lobe of the cam interacts with an inside surface of the pocket;
- a first lock housing mogul assembly, disposed in the front surface of the cover assembly, and operably connected to the connection feature on one end of the cam;
- a second lock housing mogul assembly, disposed in the rear surface of the cover assembly, and operably connected to the connection feature on the end of the cam opposite the first lock housing mogul assembly.
A lock assembly comprising:
- a rectangular cover assembly having a front surface and a rear surface;
- a cam having a generally-cylindrical body with two c-shaped slots disposed axially therein and having a wedge-shaped lobe protruding radially from the body, disposed within the cover assembly in such manner that the lobe is free to rotate within a limited envelope of rotary motion radially about the body;
- a rectangular lockbolt disposed within the cover assembly having a rounded rectangular pocket disposed therein, the pocket being oriented so that the lobe of the cam interacts with an inside surface of the pocket;
- a first lock housing mogul assembly, disposed in the front surface of the cover assembly, and having a protrusion disposed within the c-shaped slot in the cam;
- a second lock housing mogul assembly, disposed in the rear surface of the cover assembly, and having a protrusion disposed within the c-shaped slot in the cam.
