[0001] The present invention relates to a door re-locking device for a safe, and more particularly, to a door locking device for a safe that enhances the security of the safe by improving the re-locking (passive re-lock) structure of the safe door.

[0002] A financial automation device is an automated device that can provide basic financial services, such as deposits or withdrawals, regardless of location or time, without the presence of bank employees.

[0003] Since the banknote storage compartment of a financial automated teller machine stores banknotes such as cash and checks, a safe made of steel is usually installed around the banknote storage compartment to safely store and manage the stored banknotes and prevent unauthorized entry from the outside.

[0004] The safe may be configured to include a main body having a storage space for banknotes and the like inside, and a door hinged to one side of the front opening of the main body and opened and closed in a swinging manner. The door is provided with a plurality of lock shafts that penetrate one side wall and the upper and lower side walls of the door and reciprocally move to engage or disengage from the main body, and a door re-lock structure is provided to lock the lock shafts when the door is closed to prevent movement.

[0005] The locking device of the above door has an active lock structure that locks the lock shaft by operating the locking device while the door is closed, and a passive re-lock structure that operates to automatically additionally lock the shaft by a spring or other mechanical device when the glass is broken by an external force due to an unauthorized attack while the door is closed.

[0006] The active lock structure of the conventional door is configured to lock the lock shaft, and the size of the lock body itself including the actuator inside is formed large, which causes the problem of increased cost, and the size of the glass for passive release is also formed large, so when the glass is broken, the entire glass is not broken, which causes the release not to be properly implemented.

Includes a fifth guide pin (236).

[0084] According to this configuration, when the second link (220) moves laterally back and forth, the third link (230) moves laterally back and forth in conjunction therewith, and the third link (230) can move horizontally back and forth by the third guide hole (231) and the third guide pin (232), and the inner surface of the fourth guide hole (233) and the inner surface of the fifth guide hole (235) can move longitudinally back and forth by the force pushing the fourth guide pin (234) and the fifth guide pin (236), respectively.

[0085] The fourth link (240) is provided to have a length in the transverse direction on the lower back surface of the door (20), and one side of the fourth link (240) is connected to the lower part of the second link (220) by a fastening member (228).

[0086] A configuration for the fourth link (240) to move laterally reciprocally in conjunction with the laterally reciprocating movement of the second link (220), wherein the fourth link (240) has a sixth guide hole (241) having a length in the laterally direction in the middle portion thereof, a sixth guide pin (242) inserted into the sixth guide hole (241) and provided at a fixed position, a seventh guide hole (243) having a length in the diagonal direction in one side of the third link (240), a seventh guide pin (244) inserted into the seventh guide hole (243) and coupled to a third lock shaft (170) provided on one side, an eighth guide hole (245) having a length in the diagonal direction in the other side of the fourth link (240), and a third lock shaft (180) inserted into the eighth guide hole (245) and provided on the other side. Includes the 8th guide pin (246).

[0087] According to this configuration, when the second link (220) moves laterally back and forth, the fourth link (240) moves laterally back and forth in conjunction therewith, and the fourth link (240) can move horizontally back and forth by the sixth guide hole (241) and the sixth guide pin (242), and the inner surface of the seventh guide hole (243) and the inner surface of the eighth guide hole (245) can move longitudinally back and forth by the force pushing the seventh guide pin (244) and the eighth guide pin (246), respectively.

[0088] The door locking device of the safe of the present invention includes an active locking part (300, 400) that locks the lock shaft (120, 130) to prevent movement when the door (20) is closed and the first to third lock shafts (110, 120, 130, 140, 150, 160, 170, 180) move outward of the door (20) by one-way rotation of the handle (22) and are caught on the main body (10).

[0089] The above active lock (300, 400) may be composed of a first active lock (300) and a second active lock (400).

[0090] The first active lock (300) may include a swing lock member (320) that is inserted into a swing lock member insertion groove (121; FIG. 5) formed in a first lock shaft (120) to be engaged or released by swinging in conjunction with an actuator (not shown) inside a first lock body (310) provided on the back surface of the door (20) by the operation of the first locking device (23) provided on the front surface of the door (20). In addition, a swing lock member guide member (330) for guiding the swing movement of the swing lock member (320) may be coupled to the first lock shaft (120) by a fastening member (331).

[0091] By configuring the first active lock (300) to include a swing lock member (320) that swings, the size of the first lock body (310) can be reduced, which has the advantage of reducing the manufacturing cost of the first active lock (300).

[0092] The second active lock (400) may include a lifting lock member (430) that moves up and down in conjunction with an actuator (not shown) inside a second lock body (410) provided on the back surface of the door (20) by driving a second lock device (24) provided on the front surface of the door (20) to be caught or released from an lifting lock member insertion groove (131) formed on a first lock shaft (130). In addition, the second active lock member (400) may further include a lifting movement member (420) that vertically connects the actuator (not shown) inside the second lock body (410) and the lifting lock member (430) and moves up and down.

[0093] The above-mentioned lifting and moving member (420) may be formed in the shape of a plate having a short transverse length and a length to reach the first lock shaft (130) in the longitudinal direction. In this way, by configuring the second active lock part (400) so that the lifting and moving member (420) and the lifting and locking member (430) have a short transverse length and can reciprocate in the longitudinal direction, the size of the second locking body (410) can be miniaturized, which has the advantage of reducing the manufacturing cost of the second active lock part (400).

[0094] Meanwhile, the door locking device of the safe of the present invention is configured such that when the door (20) is closed and the first to third lock shafts (110, 120, 130, 140, 150, 160, 170, 180) are locked to the main body (10), and the first to third lock shafts (110, 120, 130, 140, 150, 160, 170, 180) move in the direction of being unlocked by an external force due to an unauthorized intrusion to the lock shafts (110, 120, 130, 140, 150, 160, 170, 180), a glass striking means (600) that strikes and breaks the glass (500) mounted on the door (20), and when the glass (500) is broken, the position of the mounting means (710, 840, 940) mounted on the glass (500) moves, thereby causing the lock to break. Includes a passive release unit (700, 800, 900) that locks the shaft (110, 120, 130, 140, 150, 160, 170, 180) to prevent movement.

[0095] The above passive relaxation unit (700, 800, 900) may be composed of a first passive relaxation unit (700), a second passive relaxation unit (800), and a third passive relaxation unit (900).

[0096] Referring to FIG. 5, the glass (500) can be mounted on the back surface of the door (20) in front of the first locking body (310) and the second locking body (410), and can be provided with a relatively small size so that when one side (500a) of the glass (500) is struck by the glass striking means (600), the glass (500) can be evenly broken and shattered as a whole.

[0097] The above glass striking means (600) may include a cantilever (620) having a cantilever fixing part (610) provided at one end and a free end at the other end, and configured to be deformed and rotated in a direction toward the side surface (500a) of the glass (500) centered on the cantilever fixing part (610) when an external force is applied due to unauthorized intrusion into the first lock shaft (110, 120, 130, 140), and a striking piece (640) provided at the free end side of the cantilever (620) and having a bent part (641) corresponding to the side surface (500a) of the glass (500).

[0098] A first inclined portion (229) inclined to one side is formed at the end of the link (220) coupled to the first lock shaft (110, 120, 130, 140), and a second inclined portion (630) corresponding to the first inclined portion (229) is formed at the free end of the cantilever beam (620). When an external force is applied to the above lock shaft (110, 120, 130, 140), the second inclined portion (630) moves in an inclined direction along the contact surface with the first inclined portion (229) by the force that laterally presses the first inclined portion (229), so that the cantilever beam (620) is deformed and rotates in the direction toward the side surface (500a) of the glass (500), and the side surface (500a) of the glass (500) is struck by the striking piece (640), so that the glass (500) can be broken evenly throughout.

[0099] Hereinafter, the configuration and operation of the first to third passive release parts (700, 800, 900) will be described with reference to FIGS. 6 and 7. In FIGS. 6 and 7, the glass (500) indicated by a dotted line represents a broken and fractured state, and the first wire (840) and second wire (940) indicated by dotted lines represent a cut or tension-relieved state.
