  • Patent number: 9705265
    Abstract: A configurable electrical connector key for connecting an electronic door lock to an external unit, such as a lock monitoring or control system, includes a connector key housing shaped to engage the electronic door lock and a configurable circuit mounted within the connector key housing that makes a configured interconnection between selected components within the door lock and the external unit. The combination of an electrical connector key and an electronic door lock and a system and method including multiple differently configured electrical connector keys and one or more standardized electronic door locks allow selected sensors and functions of the door lock to be enabled by selecting an appropriately configured electrical connector key.

  • Patent number: 9617757
    Abstract: Locks, systems and methods of monitoring a lock, the lock having a hub with a slot rotatable by a handle to open and close a latchbolt. A locking member is moveable into and out of engagement with the hub slot to prevent and permit movement of the hub and latchbolt. A sensor on the lock, adjacent the hub and locking member, monitors a moving lock component. The sensor may sense the position of the locking member in or out of engagement with the hub slot. The sensor may be a reed switch actuated by a magnet on the moving lock component. The lock may further include a magnet mounted on the hub and the sensor may comprise a reed switch capable of being actuated by the magnet on the hub. The lock and system may include an external control unit having an alarm for controlling operation of the lock.

  • Patent number: 9528295
    Abstract: A locking device includes an integrated circuit board specially shaped to fit the locking device and to bring a sensor on the circuit board adjacent to a moving lock component. The circuit board is preferably routed to form a convex shape that matches the locking device and provides printed circuit wiring to connect one or more sensors or other components to an external wiring harness, thereby reducing point-to-point wiring within the lock. Multiple different circuits may be provided on the same circuit board, which are automatically selected by the connectors used on different corresponding wiring harnesses and/or actuators. The design reduces assembly costs and allows rapid electrification of existing mechanical locking devices with minimal modification.

  • Patent number: 9382729
    Abstract: A release mechanism is actuated by the heat of a fire to electrically and mechanically disconnect electrical wiring from an electronic lock having a plastic housing. The electronic lock is mounted on a fire door and as it is heated by a fire on the opposite side of the fire door, mounts that hold the lock melt, releasing the electronic lock to drop away from the fire door and prevent ignition of the plastic housing. The release mechanism may use shape memory alloy wire to contract and disconnect a ribbon cable. Solder connectors may also be used to disconnect wires. Intumescent material that expands when heated is used to drive the lock mechanism away from the fire door and insulation is used to control the timing of melting.

  • Patent number: 9062475
    Abstract: A roseless trim for a mortise or tubular lock includes through bolts on a bolt circle of less than one inch (25.4 mm). Spindle hubs with a curved slot allow at least one of the through bolts to pass through the spindle hubs. A tubular lock embodiment uses arms with a cutout. The arms function as through bolts when screws attach the arms to mounting plates on opposite sides of the door. Each handle is attached to a corresponding handle base with a bushing. The handle base and small diameter bolt circle cooperate to provide the appearance that the handle extends directly into the door without a rose, escutcheon or any other attachment structure at the base of the handle.

  • Patent number: 9019067
    Abstract: An electronic lock with power failure control circuit includes a lock mechanism having a latchbolt movable between extended and a retracted positions and an electrically powered lock actuator to lock and unlock the latchbolt. The power failure control circuit includes a microcontroller and the lock is connected to a primary power source and an auxiliary power source, preferably supercapacitors and charger that can be turned on by the microcontroller and off when the charger signals a full charge. A power monitor circuit detects low voltage on the primary power supply and sets a power failure interrupt causing the microcontroller to execute power failure instructions that control the actuator so that the lock is placed into a desired locked or unlocked final state during the power failure. upon detection of the return of good power, the system resets the lock.

  • Patent number: 8922370
    Abstract: Electrified access-control technology devices for a door, particularly electrified locks for a door, having embedded circuitry therein, and methods of making the same. One or more printed circuit boards (PCBs) having various electronic circuitry are secured inside a housing that encases an access-control device, particularly a lock, for a door. The one or more PCB(s) may be embedded on an internal surface of the housing such that the embedded PCB resides inside the housing along with the lock itself. The embedded PCB(s) avoid interference of both any working components of the lock inside the housing and any openings residing in the housing.

  • Patent number: 8881637
    Abstract: An apparatus and method for releasably mounting access control components for a door lock to a door. A base element is adapted to be mounted to the door. A first wire connector element is mounted to the base element. A mounting element with combustible material attached is provided. A second wire connector element is mounted to the mounting element, and the second wire connector element is releasably connected to the first wire connector element to mount the mounting element to the base element. A spring is provided, and a retainer holds the spring in a loaded state, but in a fire event the retainer may melt, allowing the spring to apply force to the mounting element. Alternatively, an expanding material may apply the force. The force causes the wire connector elements to disconnect and allow the mounting element to separate from the base element.

  • Publication number: 20140292001
    Abstract: A door lock with integrated door position sensor includes rectangular magnets positioned behind the door strike to maximize magnetic field strength in available space limited by industry-standard dimensions for the door strike. A beveled or stepped mounting opening for the sensor is formed in a front plate of the door lock and behind a non-magnetic faceplate. The shape of the mounting opening allows the magnetic field to penetrate deeply through the faceplate and front plate to actuate the door position sensor. The sensor may be used in mortise locks or bored locks. In an alternative embodiment, the sensor is spring mounted to eliminate all mounting tolerances and ensure that the sensor is maximally forward and flush against the back of the non-magnetic faceplate.

  • Patent number: 8596330
    Abstract: A vertical door locking system includes a sliding latch mounted to a door that opens vertically, such as a garage door or corrugated self-storage door, and an electrically operated solenoid mounted at a fixed location on a guide rail for the door or the door frame. The latch includes a latchbolt that extends outward from the door to prevent the door from being raised vertically and the latchbolt has an opening at one end. The solenoid includes a spring operated solenoid rod that extends into the opening in the latchbolt to prevent the latchbolt from being retracted thereby preventing the door from being opened unless the solenoid is electrically operated to disengage the solenoid rod and release the latchbolt.

  • Patent number: 8495836
    Abstract: A drive mechanism for door hardware, such as a pushbar exit device, includes a driver for moving a component of the door hardware, a controller for controlling the operation of the driver, a sensor for detecting motion of the moving component and a spring connected between the driver and the door hardware component. The spring allows the driver to move for a period of time after the component has stopped moving. The controller monitors the sensor and moves the component until the sensor indicates that the driven component has stopped moving. The sensor produces an output signal and the controller detects an inflection point in the output signal when the component stops moving while the driver is still operating.
