AUTOMATIC DOOR OPENING DEVICE USING THERMAL EXPANSION OF SHAPE MEMORY ALLOY
When an emergency situation such as a fire occurs, a rescuee trapped in a room is embarrassed or loses judgment, and thereby a situation of forgetting how to release the locking device, repeating an erroneous operation, or the like occurs. Therefore, when a situation such as a fire occurs, a front door, which is a most effective evacuation path, cannot be used, and thereby in most cases of fire, deaths in front of the door are frequently reported. The present invention is made to improve the above-described problems, and relates to a fire safety door lock of which a lock state is automatically released by automatically operating, as illustrated in the drawing below, a spring composed of a shape memory alloy connected to a locking bar of the digital door lock when being operated, and which is capable of being opened independently without being affected by other circuits.
