20150101371 | Key Mechanism - A key mechanism comprises a rack and an external force key member, the lower part of the rack disposed with a transmission pinion on one side and ratchet means on the other side. The ratchet means comprises a first ratchet and a second ratchet arranged consecutively to one another from the top down. The rack is provided with a first step and a second step arranged consecutively to one another from the top down. An elastic retaining member is mounted on the ratchet-side of the rack, and a rack returning spring and key returning spring are respectively mounted on the rack and the external force key member. The elastic retaining member is brought into clamp connection with the first or second ratchet in the lower part under the press action on the external force key member. The key mechanism increases the range of possible password settings of the code lock. | 04-16-2015 |

20090193862 | LOCK WITH COMBINATION PINS OF NON-CIRCULAR SECTION AND ECCENTRICITY CAPABLE OF BEING POSITIONED IN ROTATION AND LOCK KEY WITH COMBINATION INDENTATIONS DIFFICULT TO REPRODUCE FRAUDULENTLY - The present invention proposes a lock with combination pins of non-circular section and eccentricity capable of being positioned in rotation, according to which the seatings or housing orifices for the pin-counterpin sets are aligned. At least one of these same orifices in the rotor two semi-pins are housed together, abutting each other and being provided with respective eccentric tips. The eccentric tips of the pair of semi-pins housed in a same orifice are capable of operating in combination indentations belonging to a same or to two different rows of cuts provided in the shaft of the key. The semi-pins of which have paraxial projections, which are reciprocal with corners formed in the transversal section of the orifice corresponding to the seating. Each semi-pin has a counterpin associated with it, which is mounted against a spring. | 08-06-2009 |
20090277239 | MASTER KEYING SYSTEM AND METHOD FOR PROGRAMMABLE LOCK CYLINDER ASSEMBLIES - A master key system and method for a reprogrammable lock cylinder with at least one first master pin and one second master pin. The first and second master pins have different bitting configurations. The master key system includes at least a first array of change key cuts corresponding to an input key bitting array and sequence of progression and at least two master key cuts corresponding to the input key bitting array and sequence of progression and each of the change key cuts. The system further comprises at least one master pin matrix including a master pin sequence for each change key cut and at least one rekey matrix including a rekey cut for each change key. Each master pin sequence represents a sequence of master pins configured to achieve the respective change key cut and the at least two master key cuts. | 11-12-2009 |
20160090752 | SELF-LEARNING LOCK AND LOCK ASSEMBLY APPARATUS - A self-learning lock cylinder assembly or lock tumbler and tools capable of teaching the self-learning key configuration of a pre-existing key is disclosed. The individual performing the self-learning does not need to have prior locksmith experience. The individual performing the self-learning procedure can verify that the original key and copies of the original key function properly within the lock cylinder prior to final assembly and installation in the lock through a self-learning test housing. The pre-installation testing eliminates problems associated with an incorrectly assembled lock cylinder | 03-31-2016 |

20110041577 | REKEYABLE LOCK ASSEMBLY WITH BLOWN CYLINDER PROTECTION - A rekeyable lock cylinder includes a plug body with a keyway opening along a longitudinal axis and a multiple of channels transverse to the axis. A rekeying feature located adjacent to the keyway opening. | 02-24-2011 |
20110154872 | REKEYABLE LOCK CYLINDER - A rekeyable lock cylinder comprises a cylinder body, a plug assembly disposed within the cylinder body and an operation error preventing unit. The cylinder body has a plurality of upper pin holes and an accommodating hole. The plug assembly comprises a plug body, a plurality of assembled rack components and a position block disposed within the plug body. The plug body has an outside wall, a keyhole, a plurality of lower pin holes and a first hole in communication with the outside wall and the keyhole. The assembled rack components are disposed at each of the lower pin holes of the plug body respectively. The operation error preventing unit comprises a first movable member disposed at the accommodating hole of the cylinder body and a second movable member disposed at the first hole of the plug body, and the first movable member may contact against the second movable member. | 06-30-2011 |

20090217720 | RAPID-CHANGE LOCK - A changeable lock assembly suitable for re-keying a lock without disassembly of the lock. The assembly includes a housing having a bore therein, and a plug rotatably mounted in the bore. The plug includes a longitudinal axis and a keyway. The keyway is adapted to receive at least a first user key and a second user key. The lock further includes a change member movable within the lock between a first position to a second position. The change member can move solely in response to operation of the second key. Thus, when the change member is in the first position, the first key operates the lock, and when the change member is in the second position, the first key does not operate the lock. The lock assembly can also employ a change tool that, when inserted into a change slot, can move a change ball from the second position back to the first position. | 09-03-2009 |
20100031717 | INTERCHANGABLE CORE ADAPTER AND METHOD OF USING SAME - An interchangeable core lock adapter is disclosed. The interchangeable core lock adapter comprises a body portion including an outer wall and an inner wall. The outer wall is configured and dimensioned for operable engagement within a large format interchangeable core housing. The inner wall configured is and dimensioned for operable reception of a small format interchangeable core lock. | 02-11-2010 |
20140069156 | REKEYABLE LOCK SYSTEM - A rekeyable lock cylinder includes a cylinder body and a plug assembly, which includes key followers normally biased for linear movement into a home position. Locking bar interfaces in the plug assembly are rotatably connected to respective key followers for simultaneous linear movement with the key followers, and are movable from a non-rotatable to a rotatable position within the plug assembly. Each interface defines a plurality of angularly-spaced unlocking cavities alignable with a locking bar operatively associated with the cylinder body and plug assembly. When the user causes the interface to move into the rotatable position, it can be rotated to re-align any or all of the unlocking cavities with the locking bar. Inasmuch as each unlocking cavity is also associated with a particular elevation of the interface's respective key follower, re-aligning one or more such cavities resets the respective elevations of the key followers so that they can accept only a different valid key. | 03-13-2014 |
