20120234059 | Symmetrical uni-directional single action centered cylinder keyless deadbolt door lock assembly for right or left hand hung doors - A deadbolt door lock assembly operates a deadbolt between unlocked and locked positions. It includes an actuator, a ring, and a biasing member. A pin interlocks with the actuator fork and rotates, in the preferred embodiment, in a clockwise direction to lock the dead bolt on either a right hand or left hand door, to which the assembly is applied. The assembly can be prefabricated to operate in a counterclockwise direction. This is achieved by relocating the locking cylinder and deadbolt body assembly to the exact center of the deadbolt. | 09-20-2012 |
20140033773 | Mortise Lock Apparatus and Electronic Operating System - The disclosure describes a locking system for a door with a mortise pocket.

The locking system also has a gear box with a worm gear that defines a notched passage that receives a lock knob shaft. A worm within the gear box is coupled to a motor that rotates the worm. The worm engages the worm gear such that the worm gear rotates when the worm rotates. A control board in the gear box is adapted to receive electronic signals and transmit them to the motor to cause the motor to rotate the worm. The gear box also has a worm gear hub that defines a keyed passage and a hub tab. The worm gear hub fits within the notched passage and the keyed passage receives the lock knob shaft. The worm gear also has two notches that the hub tab contacts individually when the gear hub rotates within the keyed passage. | 02-06-2014 |

The first case end ring extends around a lock end plate of the lock body and engages an annular shoulder of the lock end plate. An engagement element projects axially from the first case end ring to engage the lock endplate and to position the first inner case relative to the lock body. An interlocking element on the second case end ring interlocks with an outer case covering the inner case to position the outer case relative to the inner case. | 01-08-2015 |
20150075233 | WIRELESS-ACTUATED WALL-MOUNTED DEADBOLT SYSTEM - A wirelessly-actuated, wall-mountable, deadbolt system for securing the locking of a door or window is provided that includes an actuator housing for storing therein at least a part of a electronically-controlled deadbolt actuator operable from a remote controller to direct reciprocal axial movement of a deadbolt, a deadbolt mechanically linked to the electronically-controlled actuator to move reciprocally upon actuation into and out of engagement with an opening in a side surface of the door or window; and a programmable controller to control actuation of the actuator and, thus, the deadbolt. | 03-19-2015 |
20160040454 | Symmetrical Uni-Directional Single Action Centered Cylinder Keyless Deadbolt Door Lock Assembly For Right Or Left Hand Hung Doors - A deadbolt door lock assembly operates a deadbolt between unlocked and locked positions. It generally comprises an actuator, a ring, and a biasing member. The actuators has a pin that interlocks with the actuator fork and rotates, in the preferred embodiment, in a clockwise direction to lock the dead bolt on either a right hand or left hand door. Once the deadbolt is locked, a biasing member urges the ring as interlocked with the actuator and returns it to the rest position. The assembly, in the preferred embodiment, is operable in the clockwise direction without disconnecting the biasing member. Obviously, the assembly can be prefabricated to operate in a counterclockwise direction. This is all achieved for the first time on any deadbolt and deadbolt latch by relocating the locking cylinder and deadbolt body assembly to the exact center of the deadbolt. Further, the deadbolt latch has all connecting assemblies and cylinder torque blade holes aligned in the center of the latch when assembled. In this way, the deadbolt latch may be inverted, when converting from a right hand to a left hand door. The assembly may include a backstop, with indicia, to indicate the rotational direction of the ring to lock the deadbolt. The assembly may also include a stabilizing bridge to inhibit transverse rotation of mounting screws that secure the assembly to a door. | 02-11-2016 |

20140109633 | MANUALLY DRIVEN ELECTRONIC DEADBOLT ASSEMBLY WITH FREE-SPINNING BEZEL - A manually driven electronic deadbolt assembly configured with an electro mechanical coupling mechanism to selectively couple a manually operable bezel to a torque blade for operation of a deadbolt mechanism. The electro-mechanical coupling mechanism is configured such that in a locked condition the manually operable bezel is drivably decoupled from the torque blade, such that the manually operable bezel is free-spinning when rotated so as to be rendered incapable of rotating the torque blade to operate the deadbolt mechanism. Also, the electro-mechanical coupling mechanism is configured to drivably couple the manually operable bezel to the torque blade when a valid code is input to a code input mechanism to facilitate the unlocked condition, such that a rotation of the manually operable bezel effects a rotation of the torque blade to operate the deadbolt mechanism. | 04-24-2014 |

20140260446 | ENERGY ABSORBING LOCK SYSTEMS AND METHODS - A door lock secures a door when closed within a doorframe. The lock includes a bolt guide, a bolt, a bolt actuator, and a bolt receiver. The bolt includes a first portion that is adjacent to a proximal end and a second portion that is adjacent a distal end of the bolt. The actuator moves the bolt along the bolt guide between a locked position and an unlocked position. The second portion extends beyond the guide when in the locked position and is received by the receiver. The bolt deforms within the receiver and thereby predominantly absorbs energy from an intrusion load. A maximum deformation of the bolt prior to failure of the lock from the intrusion load is at least 4%, 25%, or 120% of a thickness of the bolt. A maximum deformation of the bolt prior to failure of the lock may be at least 40%, 55%, or 72% of a maximum overall deflection of the lock. The receiver may include a deformation guide that guides deformation of the bolt. | 09-18-2014 |
20150292245 | DEAD BOLT LOCK SYSTEM AND METHOD OF RETRACTING A DEAD BOLT - A dead bolt lock system including a slider member operatively coupled to a dead bolt such that when the slider member is in a first position, the dead bolt is in an extended position. When the slider member is in a second position, the dead bolt is in the retracted position. The system also includes a first movable member positioned in a path of movement of the slider member and configured to be displaced by the slider member to allow the slider member to move to the second position. The system includes a first lock having a first condition preventing the displacement of the first movable member and a second condition allowing the displacement of the first movable member, a second lock having a first condition preventing the displacement of the first movable member and a second condition allowing the displacement of the first movable member. | 10-15-2015 |
