20080276675 | PROGRAMMABLE LOCK HAVING INCIDENTAL CHANGE CONTROL - A key-operated cylinder lock for operating a bolt or a latch, that can be programmed for use with one of a plurality of user keys without disassembling the lock or replacing the tumblers, with reduction or elimination of incidental or accidental re-keying of the lock. The lock has a rotating plug having one or more retainer cavities formed into the periphery, and lock configuration change balls, movable within the lock between a first position within a driver chamber and a second position within a corresponding retainer cavity when the plug is in a programming position. The positioning of the change balls within either the pin chambers or the retainer cavities determines the key configuration that can operate the lock. The lock employs a means for isolating selectively the retainer cavities from the corresponding driver chambers when the plug is in the programming position, to prevent incidental or accidental movement of the change members from the driver chamber into the retainer cavities. | 11-13-2008 |
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 |
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 |
20100199733 | PROGRAMMABLE LOCK WITH TEMPORARY ACCESS KEY - A programmable lock for unlatching a bolt or a latch, that can be programmed for use with one or a set of main user keys without disassembling the lock or replacing the tumblers. The lock can also be programmed for operation with a temporary access key, associated with the main user key, which can operate the lock. The operation of the lock with the temporary access key can be canceled by again inserting the main user key into the keyway and operating the lock. The lock can also be automatically configured to operate with a second successive main user key that has a different though complementary configuration, by inserting and rotating the second successive main user key in the lock. | 08-12-2010 |
20110011140 | PROGRAMMABLE LOCK HAVING INCIDENTAL CHANGE CONTROL - A key-operated cylinder lock for operating a bolt or a latch, that can be programmed for use with one of a plurality of user keys without disassembling the lock or replacing the tumblers, with reduction or elimination of incidental or accidental re-keying of the lock. The lock has a rotating plug having one or more retainer cavities formed into the periphery, and lock configuration change balls, movable within the lock between a first position within a driver chamber and a second position within a corresponding retainer cavity when the plug is in a programming position. The positioning of the change balls within either the pin chambers or the retainer cavities determines the key configuration that can operate the lock. The lock employs a means for isolating selectively the retainer cavities from the corresponding driver chambers when the plug is in the programming position, to prevent incidental or accidental movement of the change members from the driver chamber into the retainer cavities. | 01-20-2011 |
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 |
20140020440 | KEY PLUG FOR A KEY-PROGRAMMABLE CYLINDER LOCK AND KEY-REMOVABLE LOCK CORE - A plug assembly for use in a key-operated lock, having a cylindrical key plug that can rotatable between a key insertion position and a control position, the key plug having a keyway and tumbler bores, an axial groove into the periphery displaced tangentially from the tumbler bores, a curved trough extending radially inwardly from the carriage groove, a control tooling slot formed radially inwardly from the curved trough. A carriage is moveable axially within the carriage groove, and has an outer surface proximate with the cylindrical periphery of the key plug. The carriage has radially-formed retainer bores that align tangentially with the tumbler bores when the carriage is in a position to accept lock configuration change balls. A separate change tooling blade can be inserted into the control tooling slot to raise any change balls within the retainer bores out through an outer opening the retainer bore. | 01-23-2014 |
20140260441 | DEVICE FOR LOCKING AN ARTICLE - A pin lock device for securing an article, including a lock base and a removable lock device that locks to the lock base. A plurality of control pins disposed in pin bores that communicate with a mounting post through tumbler channels. Alignment of recesses in the control pins releases the locking device from the post. The locking device allows the user to secure an article, such as a handgun, on the post in a secure and accessible manner. | 09-18-2014 |
20140331726 | KEY PLUG FOR A KEY-PROGRAMMABLE CYLINDER LOCK AND KEY-REMOVABLE LOCK CORE - A plug assembly for use in a key-operated lock, having a cylindrical key plug that can rotatable between a key insertion position and a control position, the key plug having a keyway and tumbler bores, an axial groove into the periphery displaced tangentially from the tumbler bores, a curved trough extending radially inwardly from the carriage groove, a control tooling slot formed radially inwardly from the curved trough. A carriage is moveable axially within the carriage groove, and has an outer surface proximate with the cylindrical periphery of the key plug. The carriage has radially-formed retainer bores that align tangentially with the tumbler bores when the carriage is in a position to accept lock configuration change balls. A separate change tooling blade can be inserted into the control tooling slot to raise any change balls within the retainer bores out through an outer opening the retainer bore. | 11-13-2014 |
20150033609 | DEVICE FOR MOUNTING AND SECURING A HANDGUN - A mounting and securing device for a handgun having a grip, a trigger, and a trigger guard. The device can include a mounting base including a means for affixing the base to a structure, a lock post extending from the mounting base having an annular groove proximate the distal end; and a trigger-blocking member including a trigger-blocking post attached to the mounting base and configured to extend behind the trigger of the handgun when mounted on the device, and a lock member comprising a body that includes a front face and a rear face, and having a bore through the rear face and into the body that is configured to accept the lock post for positioning the lock member onto the lock post, and including push-buttons for locking or unlocking the lock member to the lock post to secure the handgun. | 02-05-2015 |
