20140292001 | DOOR LOCK WITH INTEGRATED DOOR POSITION SENSOR - 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. | 10-02-2014 |
20140260929 | DOOR LOCK ACCESS CONTROL COMPONENT MOUNTING - 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. | 09-18-2014 |

20110047874 | DOOR HARDWARE DRIVE MECHANISM WITH SENSOR - 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. | 03-03-2011 |
20090212924 | INTEGRATED FIRE EXIT ALERT SYSTEM - A fire exit alert system, preferably integrated into an exit device or automatic fire exit door closer, uses sound and light to signal the location of a fire exit in darkness and smoke-obscured rooms. The alert system includes a voice signal, such as “EXIT LOCATED HERE,” to signal that the location of the voice is also the location of the exit. A white noise signal generator is used to supplement the voice signal and produces a sound that is particularly localizable by the human ear. A strobe light and a laser are used to produce a visual guide to the location of the exit. The strobe light is flashed when the word “HERE” is used in the voice signal. The laser is used to produce a cone of light that points towards the fire exit alert system. | 08-27-2009 |
20090127869 | ELECTRONIC PUSH RETRACTION EXIT DEVICE - An electronic push retraction exit device includes a support rail, a push rail and a latch mechanism having a latch bolt operably connected to the push rail and movable between latched and unlatched positions. A control circuit in the exit device drives a linear actuator to retract and hold the push rail and the latch bolt in the unlatched position. The linear actuator preferably includes a stepping motor and is connected to the push rail through a lost motion connection allowing the exit device to be mechanically operated without moving the linear actuator. The control circuit preferably includes an electrical adjustment for the retraction distance of the latch bolt and an adjustable relatch timer. The exit device may be operated by a remote switch attached to a control connection, which may be permanently closed to simulate a prior art electrically operated exit device for compatibility with third party control systems. | 05-21-2009 |
