| 20080258481 | COMPACT ELECTRIC STRIKE WITH PRELOAD RELEASE CAPABILITY - In a door strike for captivating and releasing a door bolt, the combination comprising a longitudinally elongated carrier, a longitudinally elongated solenoid supported by the carrier, the solenoid having a longitudinally movable plunger, a trip lever pivotally supported in or on the carrier, a laterally extending actuating arm pivotally supported in or on the carrier to be pivoted as the plunger moves longitudinally in response to solenoid energization, thereby to pivot the trip lever, a generally longitudinally extending blocking arm or arms pivotally supported in or on the carrier to be released for pivoting when the trip lever is pivoted, and a door bolt retainer or retainers pivotally supported in the carrier to be released for pivoting when the blocking arm or arms are released for pivoting, thereby to release the door bolt from captivation, for movement with the door. | 10-23-2008 |
| 20090056395 | Compact electric strike with preload release capability - In a door strike for captivating and releasing a door bolt, the combination comprising a longitudinally elongated carrier, a longitudinally elongated solenoid supported by the carrier, the solenoid having a longitudinally movable plunger, a trip lever pivotally supported in or on the carrier, a laterally extending actuating arm pivotally supported in or on the carrier to be pivoted as the plunger moves longitudinally in response to solenoid energization, thereby to pivot the trip lever, a generally longitudinally extending blocking arm or arms pivotally supported in or on the carrier to be released for pivoting when the trip lever is pivoted, and a door bolt retainer or retainers pivotally supported in the carrier to be released for pivoting when the blocking arm or arms are released for pivoting, thereby to release the door bolt from captivation, for movement with the door. Dual springs are compressed by the plunger in response to solenoid energization. A strut on the plunger engages solenoid structure upon plunger retraction to prevent wear or peening of the plunger. | 03-05-2009 |
| 20090308112 | Multiple door locking control - The method of controlling unlocking of one or both side by side doors, that include providing two rotary input devices; providing first means responsive to rotation of one of the devices, to unlock one of the doors; providing second means responsive to rotation of the other of the devices to unlock both of the doors, the second means operatively coupled to the first means, to activate the first means after predetermined rotation of the other device. | 12-17-2009 |
| 20100213724 | Multiple point door locking system, with handle turning direction control - A multi-function door lock system, comprising in combination, a frame having opposite sides, and installable on a door openable between an interior space and an exterior space, a deadbolt and a door latch carried by the frame to move between retracted and extended positions, a first rotary control located at one level on the frame to control deadbolt movement between extended and retracted positions via primary cam mechanism, a second rotary control at another level on the frame to control latch movement between extended and retracted positions, via secondary cam mechanism, means operatively connected between said secondary cam mechanism and the primary cam mechanism to effect deadbolt movement as aforesaid, in response to operation of the second rotary control, as effected via rotary input to the second rotary control from only one side of the frame. Means is also provided to be responsive to reverse rotation of the first rotary control to effect latch retraction independently of deadbolt displacement. | 08-26-2010 |
| 20100236302 | Multiple point door locking system - A multi-function door lock system, comprising in combination, a frame having opposite sides, and installable on a door openable between an interior space and an exterior space, a deadbolt and a door latch carried by the frame to move between retracted and extended positions, a first rotary control located at one level on the frame to control deadbolt movement between extended and retracted positions via primary cam mechanism, a second rotary control at another level on the frame to control latch movement between extended and retracted positions, via secondary cam mechanism, means operatively connected between said secondary cam mechanism and the primary cam mechanism to effect deadbolt movement as aforesaid, in response to operation of the second rotary control, as effected via rotary input to the second rotary control from only one side of the frame. Means is also provided to be responsive to reverse rotation of the first rotary control to effect latch retraction independently of deadbolt displacement. | 09-23-2010 |
| 20110192203 | Adjustable installation of door locking system - In a drive train between a door handle having a first axis of rotation and a rotary lock part carried on a door to have a second axis of rotation, the drive train accommodating to possible misalignment of those axes, the drive train including a carrier, a rack carried by the carrier, and movable in a first lateral direction in response to door handle rotation, a gear located to rotatably drive the rotary lock part in response to rack movement in the first lateral direction, relative to the carrier, and means to adjust the position of the rack in a second lateral direction, to compensate for mis-alignment of the first and second axes. | 08-11-2011 |
| 20110252709 | Multiple access door lock mechanism - In combination, a door, two latches at an edge of the door, and door latch operating components at opposite sides of the door; displaceable structure in the door having a position blocking movement of the latches, first mechanism responsive to displacement of one of the components for displacing the structure from blocking position to allow movement of the latches, for door opening; and electrically operable actuating means for effecting displacement of the structure from blocking position to allow movement of the latches, for door opening. | 10-20-2011 |
| 20110285149 | Multiple access door lock mechanism with reversible cam actuation - In combination a door, latch structure at an edge of the door, and independently opens the door latch operating components at opposite sides of the door, displaceable structure in the door having a position blocking movement of the latch structure, first means responsive to displacement of a selected one of the components for displacing the structure from the blocking position to allow movement of the latch structure, for door opening, and the first means including a rotatable cam having reversible positions in each of which motion is transmitted to the displacement structure in response to displacement of the respective components. | 11-24-2011 |
