Abstract: PURPOSE: An automatic door unlocking device in case of fire is provided to automatically unlock the door according to temperature rise in fire. CONSTITUTION: An automatic door unlocking device comprises a pressure plate (100), a pair of elastomers (200), a pair of supporters (300), and a pair of separation preventing protrusions (400). The pressure plate is installed in a groove unit (11) of a striker plate (10) and separates a latch bolt from the groove unit by pressurizing the latch bolt in fire. A pair of the elastomers is installed on the bottom surface of the groove unit and lifts the pressure plate from the bottom surface of the groove unit so that the pressure plate pressurizes the latch bolt. A pair of the supporters is individually installed on one end and the other end of an inlet of the groove unit and individually supports one end and the other end of the pressure plate in a normal time. A pair of the supporters releases the support on the pressure plate by being bent according to temperature rise in fire.
