20080224481 | Electric strike - An electric strike comprising a housing and a keeper pivotally mounted to said housing. A solenoid is arranged internal to the housing and movable between fail-safe and fail-secure positions. A two position mode control slot is included in the housing and a mode control screw is included in the mode control slot. The screw is capable of being tightened in each of the two positions in the control slot. The screw is changeable between the two of the positions without removal of the screw. The solenoid is in the fail-safe position when the screw is in one of the two positions and in the fail-secure position when the screw is in the other of the two positions. | 09-18-2008 |
20100123323 | ELECTRIC LATCH RETRACTION BAR - An electric latch retraction device comprising a housing for receiving a plurality of internal components of the electric latch retraction device. An actuator mechanism is included in the housing, the actuator mechanism is adapted to impart linear movement on a latch, such that the latch is retracted towards the housing. A holding mechanism is also included in the housing, the holding mechanism holds the latch in a fully retracted position. | 05-20-2010 |
20110181060 | ELECTRIC STRIKE - An electric strike according to the present invention comprises a housing, and an actuator mounted to the housing to switch operation of said strike between open and locked modes. In changing the modes the actuator provides lateral motion and a blocking element is included that is also mounted to the housing and cooperates with the actuator. The actuator's lateral motion causes rotational movement in the blocking element to switch between said open and locked modes. Different embodiments of the present invention can operate as dual mode electric strikes wherein the actuator is movable between fail-safe and fail-secure positions, and can include switches and paddles to monitor the position or condition of certain mechanisms in or working with the strikes. In some embodiments the blocking element can be rotatably mounted to the housing at a plurality of rotation mounting points and can comprise a plurality of blocking surfaces. In other embodiments, at least one of the one or more blocking surfaces having a pre-load movement mechanism to reduce friction with the keeper. | 07-28-2011 |
20130321125 | DELAYED EGRESS DEVICE OR LOCK WITH ENHANCED VISIBILITY - A delayed egress locking device that has an improved illumination system that signals when the lock is actuated. The illumination system can also signal the stages of conditions in a delayed egress sequence. The locking device is also directed to a security system for securing a door, wherein egress through the door is delayed for a time interval once the locking device is actuated. The locking device can also include a timing device, wherein the timing device can measure a time interval following the actuation of the locking device. The locking device can also include an illumination system, which can comprise light sources, that displays a countdown when the locking device is actuated, as well as an audio system which alerts when the locking device is actuated. | 12-05-2013 |
