20080202181ANTI-TAMPERING ARRANGEMENTS FOR PIN TUMBLER CYLINDER LOCKS - A pin tumbler cylinder lock includes a shell, a plug, and at least first and second tumbler pins and first and second driver pins. At least the first driver pin extends into a corresponding plug channel when the plug is in a locked condition, such that rotation of the plug with respect to the shell is blocked. The lock is configured such that at least the first driver pin is separated from the first tumbler pin by a gap when the plug is in the locked condition. When the first and second tumbler pins are raised without the proper key and the gap between the first tumbler pin and the first driver pin is eliminated, the second tumbler pin extends across the shear line and into the corresponding shell channel.08-28-2008

20080209962LOCKER LOCK - A lock includes a lock housing, a lock interface, a rotary locking member, a locking bolt, and a locking mechanism. The rotary locking member extends from a side portion of the lock housing, the rotary locking member being rotatable about a first axis between a locking position and a releasing position. The locking bolt is configured to hold the rotary locking element in the locking position when the locking bolt is in a first position and to allow the rotary locking member to rotate from the locking position to the releasing position when the locking bolt is in a second position. The locking mechanism is configured to slide the locking bolt from the first position to the second position in response to proper manipulation of the lock interface.09-04-2008
20090193860MULTIPOINT DOOR LOCK - A lock assembly that secures a door to an adjacent frame. The assembly includes an elongated base, a cam assembly mounted to the base including a housing, a lever, and a sliding member having a first end slidably connected to the lever and movable in a direction perpendicular to the base by rotation of the lever, an extension actuator having a proximal end movably connected to a second end of the sliding member, and a lock mechanism mounted to the elongated base and movable between unlocked and locked positions. The second end of the sliding member extends to a position within the housing upon full rotation of the lever. The extension actuator and base may permit modular addition of lock mechanisms at multiple locations.08-06-2009
20090282879LOCK ASSEMBLY WITH ROTARY LOCKING MEMBER - A lock includes a rotary locking member, a locking bolt, and an electrically operable mechanism. The rotary locking member is rotatable about a first axis between a locking position and a releasing position. The locking bolt is configured to hold the rotary locking member in the locking position when the locking bolt is in a first position. The electrically operable mechanism is configured to move the locking bolt in a direction parallel to the first axis from the first position to a second position in response to an electrical signal supplied to the electrically operable mechanism. Movement of the locking bolt to the second position allows the rotary locking member to rotate from the locking position to the releasing position.11-19-2009
20090308113LOCKER LOCK - A lock includes a lock housing, a lock interface, a rotary locking member, a locking bolt, and a locking mechanism. The rotary locking member extends from a side portion of the lock housing, the rotary locking member being rotatable about a first axis between a locking position and a releasing position. The locking bolt is configured to hold the rotary locking element in the locking position when the locking bolt is in a first position and to allow the rotary locking member to rotate from the locking position to the releasing position when the locking bolt is in a second position. The locking mechanism is configured to slide the locking bolt from the first position to the second position in response to proper manipulation of the lock interface.12-17-2009
20110100074SAFE WITH DUAL LOCKING MECHANISM - A safe for providing security and storage of personal items. The safe includes a housing, a door, a user operable locking mechanism and a user operable release mechanism. The door can be opened only upon both proper manipulation of the user operable locking mechanism and proper manipulation of the user operable release mechanism. The user operable release mechanism is disposed to reduce the risk of theft of the contents of the safe by unauthorized attempts to manipulate the release mechanism. The safe may include a mounting arrangement for mounting the housing to a structure to reduce the risk of theft of the safe.05-05-2011
20110132049MECHANICAL PUSHBUTTON LOCKING ARRANGEMENTS - A lock includes a housing, a keypad disposed on the housing, and a latch assembled with the housing. The keypad includes a plurality of button assemblies, each including an axially depressible button member including a camming surface, a lock wheel having a plurality of camming teeth, and a latch releasing feature secured to the lock wheel for rotation therewith. Pressing the button member causes the camming surface to engage one of the plurality of calming teeth, thereby incrementally rotating the lock wheel between a plurality of rotational positions. When the button members of a predetermined one or more of the plurality of button assemblies are depressed a predetermined number of times, the latch releasing features of each of the plurality of button assemblies align with a plurality of blocking features of the latch to permit lateral sliding movement of the latch from a locked condition to an unlocked condition.06-09-2011
