| 20090031769 | HIGH - SECURITY ROTATING BOLT LOCK - A cylinder lock having a body and a modified cam, the cylinder lock being adapted for moving an external element arranged to engage the modified cam, so that the external element slides axially on the cylinder lock body. In a preferred embodiment, the inventive cylinder lock is designed to utilize a helical cam which engages a movable external element or slider, and this design is referred to as the HC cylinder lock. When operated by rotating the appropriate key within it, the movable external element can be moved in a linear fashion along the length of the HC cylinder lock thus converting rotational motion of the key to axial motion of the external element. The external element is arranged to engage an eccentric pin formed as part of a rotating bolt which rotates on an orthogonal axis to the cylinder plug in response to said sliding motion, for the function of locking or unlocking a device. The streamlined design of the inventive HC cylinder lock enables efficient placement of a door lock within the hollow volume of a door to provide locking action. | 02-05-2009 |

Dimensions of a key insertion and extraction direction, which is from a position where the plurality of key matching members are inserted into the plurality of locking holes to where they contact with the inner surface of the plurality of locking holes by a move operation in a key insertion direction of the key plug, are set to be at least two small and large dimensions which are different from one another. | 02-05-2009 |
| 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 |
| 20100206027 | CYLINDER LOCK AND KEY COMBINATION WITH A BLOCKING ELEMENT IN THE LOCK - A cylinder lock and key combination is disclosed. The lock comprises a housing ( | 08-19-2010 |
| 20100319420 | WAFER CYLINDER HAVING BLOCKABLE WAFER TUMBLERS - The invention relates to a cylinder lock of the type of a disk tumbler cylinder having a cylinder housing and a cylinder core rotatable therein, with a plurality of blockable disk tumblers being provided in the cylinder core which have at least one respective engagement section. The disk tumblers are movable between an unlatched position and a latched position and are biased along a respective direction of bias into the latched position. In the latched position, the respective engagement section engages into an associated cut-out in the cylinder housing to block the cylinder core against a rotary movement relative to the cylinder housing. The cylinder core is rotatable in a rotary opening direction relative to the cylinder housing when the disk tumblers are in the unlatched position. At least one of the disk tumblers has a toothed zone which can be brought into engagement with a counter-toothed zone of the cylinder lock such that the disk tumbler is blocked against a movement opposite to the respective direction of bias when the disk tumbler is in the latched position and a torque is exerted onto the cylinder core in the rotary opening direction. | 12-23-2010 |

| 20090277236 | QUICKLY REKEYABLE LOCK CYLINDER AND PLUG ASSEMBLY THEREOF - A quickly rekeyable lock cylinder comprises a cylinder body and a plug assembly disposed within the cylinder body. The plug assembly comprises a plug body, a position block disposed at the plug body, a first rack group and a second rack group. The plug body has a longitudinal axis, a transverse axis vertical to the longitudinal axis and a rekeying tool opening. The first rack group has a plurality of first rack components. The second rack group may push the position block to move and has a plurality of second rack components in engagement with the first rack components and at least one tool-receiving portion pushed by the rekeying tool. The second rack components can move along transverse axis of the plug body to release engagement with the first rack components. | 11-12-2009 |
| 20100005842 | KEY-REMOVABLE LOCK CORE - A key-removable lock core that is retained in a core receptacle by a retaining lug, and which can operated by an operating key to align the pins of the pin chambers for shear at the operating shear line, and to allow the key plug to be rotated, and which employs a control tool with the operating key for manipulating the pins into alignment for shear at the control shear line, to allow the sleeve and the key plug together to be rotated, to move the retaining lug on the sleeve between a projected position in which the lug is engaged behind a rearward-facing shoulder in the core receptacle to retain the core in the receptacle, and a retracted position within the profile of the core | 01-14-2010 |
| 070369000 | Key only controlled | 6 |
| 20090031771 | CYLINDER LOCK AND UNLOCKING DEVICE COMPRISING THEREOF - A cylinder lock includes a sleeve having a locking hole, a key plug housed in the sleeve and having an output portion to output an interrupted motion of a clutch device by moving in an insertion and extraction direction by an insertion and extraction of a matching key, a key matching member movably supported to the key plug, arranged to be insertable and removable in the locking hole and withdrawn from the locking hole by an insertion of the matching key into the key plug, and a key plug locking mechanism for locking the key plug into the sleeve in the state that the key matching member is inserted into the locking hole. The key matching member is arranged with gaps between an inner surface of the locking hole in a key insertion and extraction direction in the state that the key plug is locked into the sleeve by the key plug locking mechanism. | 02-05-2009 |
| 20110232341 | KEY-REMOVABLE LOCK CORE - A key-removable lock core that is retained in a core receptacle by a retaining lug, and which can operated by an operating key to align the pins of the pin chambers for shear at the operating shear line, and to allow the key plug to be rotated, and which employs a control tool with the operating key for manipulating the pins into alignment for shear at the control shear line, to allow the sleeve and the key plug together to be rotated, to move the retaining lug on the sleeve between a projected position in which the lug is engaged behind a rearward-facing shoulder in the core receptacle to retain the core in the receptacle, and a retracted position within the profile of the core. | 09-29-2011 |
| 20120204611 | EXCHANGEABLE CYLINDER LOCK ASSEMBLY - An exchangeable cylinder lock includes a plug shell connected to a pin chest. A locking pin is disposed in a radial pin hole in the pin chest and is biased to protrude from an aperture in a cover plate and to engage a lock housing. The locking pin is depressable to retract for disengaging from the lock housing. A locking ring is disposed around the plug proximate to the locking pin, and has at least one indentation. When the plug is rotated using a right key, the locking ring can be rotated to align the indentation with the locking pin so as to permit depression of the locking pin, or to move the indentation away from the locking pin so as to prevent depression of the locking pin. | 08-16-2012 |
