20100170312 | ELECTROMECHANICAL CYLINDER LOCK - An electromechanical cylinder lock includes an outer lock shell and a rotatable lock barrel located therein which is controlled by dual locking features. A side bar or fence selectively blocks and permits rotation of the barrel with respect to the shell in response to insertion of a key into a keyway in the barrel. A slider bar is movable between a blocking position in which the side bar is prevented from permitting rotation of the barrel, and an unblocking position in which the side bar permits rotation of the barrel. Alternately, a blocking mechanism is provided to block motion of tumbler pins in the cylinder lock. A shape memory alloy actuator, such as a wire made of nitinol, disposed in the barrel is activated by an electric current in response to determination by an electronic control device whether an attempt to open the lock is authorized. Thermal interlock protection from external heating of the lock is also provided. | 07-08-2010 |

20080223097 | HIERARCHICAL CYLINDER LOCK SYSTEMS - A hierarchical lock system includes a first cylinder lock having a cylindrical plug, rotatable, reciprocating tumbler pins, a slider disposed within the plug and a side bar that cooperates with the cylinder plug, the slider, and the tumbler pins to control rotation of the lock. A second cylindrical lock includes a cylindrical plug, reciprocating tumbler pins, a slider, and a side bar that cooperates with the cylindrical plug and the slider. A first key is configured to open both the first and second locks by elevating and rotating the tumbler pins, and moving the slider to an unlocked position with respect to the side bar. A second key is able to open only the second cylindrical locks by elevating but not rotating the tumbler pins and by moving the slider to an unlocked position with respect to the side bar. | 09-18-2008 |
20080250830 | LOCK, KEY BLANK, AND KEY OF A HIERARCHICAL LOCK SYSTEM - A lock system includes keys, key blanks, keyways, and lock cylinders, and the keys or key blanks have opposite sides formed with grooves for cooperating with a conforming keyway. More particularly, the sides of the key or key blank have a portion grooved for registration, another portion grooved for top-level hierarchical master keying, and two other portions, one on each side of the blade, for further master key variations and different combinations. One of the two further sections being curvilinear and the other rectangular or angular cuts. The conforming keyway of the lock includes ridges and grooves corresponding to the grooves and ridges, respectively, of the key or key blank. Instruments other than keys or key blanks may be used to enter the grooves and ridges of the keyway to operate the lock without the use of a precisely configured key. | 10-16-2008 |
20090044579 | CYLINDER LOCK ASSEMBLY WITH A TAILPIECE ROTATIONALLY COUPLED TO THE CYLINDER PLUG - The present application relates to lock assemblies that provide a secondary coupling point, utilizing an anti-rotation pin or extended tailpiece leg or other method, which rotationally couples the tailpiece to the cylinder plug, thereby preventing rotation of the tailpiece independently of the cylinder plug. Therefore, a tailpiece within a bolt cam or other actuator used to withdraw a bolt or unlock a lockset cannot be rotated after the primary means for connecting the tail piece to the cylinder plug has been forcibly removed, severed, or destroyed. | 02-19-2009 |
20090241620 | Cylinder Lock and Auxiliary Locking Mechanism - A tumbler pin lock includes an auxiliary locking mechanism including an auxiliary locking pin to provide enhance locking in addition to the locking provided by the tumbler pins so that the lock remains locked even if the tumblers are picked or bumped into their unlocked positions. | 10-01-2009 |

The key includes at least one movable element disposed within a recess formed in the blade and including a contour surface exposed to the exterior of the key blade. The contour surface may include external contour features that correspond in shape to at least a portion of the contour features of the keyway. The movable element may be movable within the recess, when it engages a blocking member within the keyway, and after such movement, the element will engage a locking element within the lock. | 07-10-2014 |
