| 20090282880 | KEYED LOCK DOOR HANDLE - A door handle assembly that can be locked and unlocked using a key. The door handle assembly includes a bolt that is movable from an extended position to a retracted position. The first handle is coupled to the bolt and adapted to cause the bolt to retract when the first handle is pushed. A second handle is coupled to the bolt and adapted to cause the bolt to retract when the second handle is pulled. A key locking mechanism is coupled to the first handle. The key locking mechanism is adapted to selectively prevent the bolt from moving to the retracted position. A safety locking mechanism is coupled to the second handle. The safety locking mechanism is adapted to selectively prevent the bolt from moving to the retracted position. | 11-19-2009 |
| 20110016936 | KEY AND CORE WITH SIDE PIN - A lock core and key blank are disclosed. The disclosed lock core includes a core body, a core sleeve, a core plug, and a side pin assembly including a side pin, a region pin, and a spring. | 01-27-2011 |
| 20140041427 | HYBRID LOCK CYLINDER - The present disclosure provides for a lock cylinder having a rotatable spindle with at least one disc and at least one wafer housing rotatingly engaged therewith. A slidable wafer is carried on the wafer housing. A locking bar is operable to prevent rotation of the lock cylinder in a locked position and permit rotation of the lock cylinder in an unlocked position. | 02-13-2014 |
| 20160376815 | HIGH-SECURITY CYLINDER LOCK BASED ON BRIDGE TUMBLERS - A bridge tumbler lock has tumblers that both slide and pivot, with their motion controlled by pairs of key interfaces. A sidebar is released to permit lock opening movement when all tumblers are in their correct positions. This results in a lock that is resistant to release of information due to partially correct key combinations occurring in the course of a lock picking attempt and thus enables enhanced security in an economical, effective lock construction. | 12-29-2016 |

| 20100050715 | Magnetic coded lock mechanism - A magnetic coded lock mechanism which includes a key having a plurality of recesses and a plurality of permanent magnets properly coded around the key body, a cylindrical plug having a keyway aperture, a plurality of main apertures as passages, which contain movable key pins, a plurality of auxiliary apertures as magnetic locking passages corresponding to coded key, which contain movable magnets, a plurality of fixed magnets coded around the cylindrical plug as the way for biasing the magnets and locking pins toward the keyway, and a stationary tubular cylinder having a longitudinal aperture disposed in the center for receiving the cylindrical plug, a plurality of radial main apertures as passages for mating with the main apertures of the cylindrical plug, each passage containing a driver pin with a coil spring, and radial auxiliary apertures as passages for mating with the auxiliary apertures of the cylindrical plug, each passage containing a locking pin, whereby in a locked position, the driver pins and locking pins straddle both passages to prevent relative movement between the cylindrical plug and the tubular cylinder, and in an unlocked position, when the key is insert into the keyway, the key recesses drive the key pins in the main apertures of the cylindrical plug to a predetermined level and the movable magnets in auxiliary apertures of the cylindrical plug are repelled radially outward along the passages to a predetermined level respectively, so as to cause unlocking of the magnetic lock mechanism. | 03-04-2010 |
| 20130000367 | Disk Tumbler Lock and an Improved Key and Restrictive Keyway - A disc tumbler lock having a code range angle, the disc tumbler lock including at least: at least one tumbler and a guard tumbler, the at least one tumbler and the guard tumbler defining a keyway aperture there through; wherein the at least one tumbler includes at least: a key engaging surface defining a key engaging zone, the key engaging zone having a first radius defining the major extent of the key engaging zone, and the key engaging zone having a second radius defining the minor extent of the key engaging zone; wherein the guard tumbler defines: a restrictive aperture comprising a restrictive width having a minimum dimension less than or equal to the sum of the first radius defining the major extent of the key engaging zone and the second radius of the minor extent defining the key engaging zone multiplied by the sine of one half of the following: the code range angle of the lock, minus the angular measure between a last code angle for the lock and a second to last code angle for the lock, minus the angular span of the key engaging surface. | 01-03-2013 |

| 20090090150 | TUMBLER-TYPE KEY VERIFICATION SYSTEM - A tumbler-type key verification system including a tumbler-type key and a lock apparatus. The lock apparatus includes a support member, a movable member movable relative to the support member, tumblers which are biased by tumbler springs and are arranged to engage with the support member and the movable member, and a lock mechanism that reinforces the locking strength of the tumblers. The lock mechanism having a two-piece structure including a first piece movably accommodated in the movable member and a second piece movably accommodated in the support member. The lock mechanism reinforces the locking strength of the tumblers by having the first piece or the second piece engage both the movable member and the support member before the tumbler-type key is inserted into the lock apparatus or when the tumbler-type key is being inserted into the lock apparatus. | 04-09-2009 |
| 20090266123 | Lock Device with a Lock Cylinder and a Key - The invention relates to a lock device comprising a key and a lock cylinder, said lock cylinder comprising a fixed cylinder housing and a cylinder core mounted to rotate therein. The key shaft ( | 10-29-2009 |
| 20100077812 | Unlocking Device for Concealing Keyhole of Lock - An unlocking device includes a casing mounted to a side of a lock having a keyhole. A movable body is rotatably received in the casing about an axis. The movable body has a closed end having a hole. A key receiving seat is received in the movable body and has a key receiving hole. The keyhole is normally blocked by the closed end of the movable body. The movable body can be rotated to align the hole with the keyhole and the key receiving hole. A block is fixed to the movable body and includes a through-hole extending along the axis. A manually rotatable linking rod extends through the through-hole and has an engaging portion for coupling a key received in the key receiving hole. The key can be moved into the keyhole by moving the linking rod along the axis and can be rotated for locking or unlocking operation. | 04-01-2010 |
| 20120160000 | LOCKING MECHANISM AND A LOCKING DEVICE COMPRISING THE SAME - A pin-tumbler locking mechanism comprising a lock-core with an elongated key slot and a series of bores arranged in a plane of the key slot for a corresponding series of driver pins of various lengths slidably received in the bores. The lock-core is normally supported in lock casing. A corresponding series of spring-supported key pins is seated in a series of bores coaxially with the driver pins so that normally at least some of the key pins are adapted to push respective driver pins to project into the key slot each by a different extent according to the respective lengths thereof; a key comprising alternately teeth and notches so that when inserted into the key slot, the driver pin ends contacting the key pins become flushed with planar surface to allow a sliding movement of the lock-core within the lock casing. | 06-28-2012 |
| 20140041426 | DISC ALIGNMENT MECHANISM - A lock assembly is provided with a plurality of discs, one or more driver discs and a pivoting component that interacts with the discs and driver discs, providing anti-pick features. | 02-13-2014 |
