Abstract

A safe door includes: a body part; a locking part configured to be in one of a locked state in which the lock part protrudes from the body part and an open state in which the locking part is deviated from the locked state; and a relocking unit configured to restrict a movement of the locking part. The relocking unit includes: an actuator; a relocking bracket provided in a bracket form covering an outer shape of the actuator and movable by operation of the actuator; and a relocking member mounted on an end of the relocking bracket and configured to restrain the locking part by movement of the relocking bracket.

First claim

What is claimed is:

1 . A safe door comprising:
a body part; a locking part configured to be in one of a locked state in which the lock part protrudes from the body part and an open state in which the locking part is deviated from the locked state; a relocking unit configured to restrict a movement of the locking part; a main support part supporting the locking part and configured to be movable with respect to the body part; a connector having one side in which a virtual rotation axis extending in a front and rear direction, and the other side connected to the main support part; and a base part mounted on the body part to support the relocking unit, wherein the relocking unit comprises: an actuator; a relocking bracket provided in a bracket form covering an outer shape of the actuator and movable by operation of the actuator; and a relocking member mounted on an end of the relocking bracket and configured to restrain the locking part by movement of the relocking bracket, wherein the relocking member includes: a relocking pin configured to be fixed to a first main rod of the main support part to restrain the locking part; a connecting rod having one end portion connected to an end portion of the relocking bracket and the other end portion connected to the relocking pin, a connecting groove being formed in the other end portion of the connecting rod; a connecting pin mounted in the connecting groove to be removable at an end of the connecting rod and inserted into a fixing groove formed in the body part when the relocking pin restrains the main support part; and an elastic spring for elastically supporting the connecting pin in the connecting groove.

2 . The safe door of claim 1 , wherein the relocking unit allows the locking part to be in one of the locked state and the open state through a movement of the relocking member in response to the operation of the actuator.

3 . The safe door of claim 1 , wherein the relocking bracket comprises:
a bracket frame provided in a bracket form covering a side and a bottom of the actuator; and a bracket guide groove formed on one side of the bracket frame to be parallel to a moving direction of the relocking pin.

4 . The safe door of claim 3 , further comprising:
safety glass disposed adjacent to the body part and configured to be broken when an external force is applied to force the locking part to change from the locked state to the open state.

5 . The safe door of claim 4 , wherein the safety glass is disposed between the body part and the base part, and includes a catching hole extending in an up and down direction.

6 . The safe door of claim 5 , wherein the relocking bracket further comprises:
a bracket hook protruding toward the safety glass to be hooked in the catching hole of the safety glass.

7 . The safe door of claim 6 , wherein the bracket hook is formed integrally with the other side of the bracket frame to be lifted and lowered together with the bracket frame when the bracket frame is lifted and lowered in the locked state for locking the locking part and the open state deviated from the locked state.

8 . The safe door of claim 1 , wherein the locking part includes a plurality of locking shafts spaced apart from each other along a periphery of the body part, and
wherein the main support part is configured to be movable in a first direction in response to the connector rotating about the rotation axis such that the locking part is switched from one of the locked state and the open state to the other state, some of the plurality of locking shafts are configured to move in the first direction, and others of the plurality of locking shafts are configured to move in a second direction perpendicular to the first direction.

9 . A safe comprising:
a safe case having a predetermined space formed inside; and a safe door configured to selectively open and close the space inside the safe case with respect to an outside, wherein the safe door includes: a body part; a locking part configured to be in one of a locked state in which the locking part protrudes from the body part toward the outside and an open state in which the locking part is deviated from the locked state; a relocking unit for restricting movement of the locking part when an external impact is applied; and safety glass disposed adjacent to the body part and configured to broken when an external force is applied to force the locking part to change from the locked state to the open state, wherein the relocking unit includes: an actuator; a relocking bracket provided in a bracket form covering an outer shape of the actuator and movable by operation of the actuator; and a relocking member mounted on an end of the relocking bracket and configured to restrain the locking part when the relocking bracket moves, wherein the relocking bracket includes a bracket hook protruding toward the safety glass to be caught in a catching hole of the safety glass.

10 . The safe of claim 9 , wherein the relocking unit allows the locking part to be in one of the locked state and the open state through movement of the relocking member in response to the operation of the actuator.

11 . A safe door comprising:
a body part; a locking part configured to be in one of a locked state in which the locking part protrudes from the body part and an open state in which the locking part is deviated from the locked state; a relocking unit configured to restrict a movement of the locking part; safety glass disposed adjacent to the body part and configured to broken when an external force is applied to force the locking part to change from the locked state to the open state, wherein the relocking unit includes: an actuator; a relocking bracket provided in a bracket form covering an outer shape of the actuator and movable by operation of the actuator; and a relocking member mounted on an end of the relocking bracket and configured to restrain the locking part when the relocking bracket moves, wherein the relocking bracket includes a bracket hook protruding toward the safety glass to be caught in a catching hole of the safety glass.
