Title: EMERGENCY CONTROL METHOD OF SAFE DOOR AND EMERGENCY OPENING APPARATUS FOR SAFE DOOR
Abstract:
The present invention relates to an emergency control method of a safe door and an emergency opening apparatus for a safe door and, more particularly, to an emergency control method of a safe door and an emergency opening apparatus for a safe door, in which, when the door cannot be opened due to a failure (defect) or expiration of the validity term for use of an installed motor, by the operation of which a latch arranged in the safe door is expected to be locked/released, the latch can be released to open a safe by switching the mode of an input module disposed at the upper end of the safe to an emergency mode and then operating an emergency motor. In order to implement this, the present invention is achieved by a method for controlling the safe door, the method comprising: a number input step (S2) of switching the mode of an input module included in the safe to a normal mode (S1) and inputting a number by a user; an input number and password comparison step (S3) of comparing the input number with a password stored in a memory, wherein a control module operates a lock device to lock/unlock the lock device when the input number matches the password; an emergency input number step (S5) of switching the mode of the input module to an emergency mode (S4) and inputting an emergency number by the user; and an emergency input number and emergency password comparison step (S6) of comparing the input emergency number with an emergency password stored in the memory, wherein the control module operates the lock device to lock/unlock the lock device when the input emergency number matches the emergency password. Further, the present invention comprises a safe latch apparatus comprising: a door (120) for opening and closing a safe (100); a locking device (130) for locking/unlocking the door (120), wherein the locking device (130) includes a latch (132) having a first bracket (131) and a latch protrusion (132a) arranged on one end thereof and having a moving protrusion (132b) and a guide groove (132c) arranged on the other end thereof, the first bracket (131) being fixed to the inner surface of the door (120) and having a guide protrusion (131a); a cam (133) having a sun gear (133b) formed on the outer peripheral part thereof around a rotation shaft (133a), the cam (133) having a guide groove (133c) which is engaged with the moving protrusion (132a) to guide a movement direction of the moving protrusion (132a); a second bracket (134) for covering the latch (132) and the cam (133); and a motor (M) for providing an interworking rotational force to a planet gear (135) engaged with the sun gear (133b), wherein the first bracket (131) comprises a horizontal emergency link (136) horizontally moving by an action of an emergency motor (EM); and a vertical emergency link (137) moving vertically downward by the horizontal movement of the horizontal emergency link (136).
