  • An angle for disposing the side protection portion 114 may be appropriately changed depending on required conditions and design specifications.
  • a side protection portion 114 disposed to be inclined at an angle of approximately 45° will be described as an example.
  • the side protection portion 114 may be formed by partially bending a side end of the base plate 112 described above. In some cases, it is possible to separately manufacture the side protection portion and combine the side protection portion with the base plate.
  • a method of breaking the locking member 250 through an attack on the side surface of the safe 100 can be expected. That is, as shown in FIG. 4 , a method of breaking the locking assembly 240 through the sliding member 220 can be expected, in which the locking assembly 240 is broken by directly attacking the locking member 250 using a hammer after making a hole on the outer wall of the side surface of the safe 100 with a drill. Since slide movement of the sliding member 220 can be allowed if the locking assembly 240 is broken like this, constraint of the door locking part 230 can be released using a handle.
  • a state of constraining the slide movement of the sliding member 220 may be maintained comparatively stably although a forced shock is applied from outside.
  • auxiliary locking part 260 may operate as the safety plate 270 is broken, the constrained state of the sliding member 220 can be maintained by the auxiliary locking part 260. Accordingly, the intruder should release the constrained state of the auxiliary locking part 260 or perform another release work in order to release the locking state of the door locking part 230. Accordingly, a time required to open the safe 100 is delayed as much, and the intruder cannot open the safe 100 within a short period of time as intended.
  • a method of breaking the locking assembly 240 through an attack on the side surface of the safe 100 can be expected. That is, as shown in FIG. 4 , a method of breaking the locking assembly 240 using a chisel or a hammer after making a hole on the outer wall of the side surface of the safe 100 with a drill can be expected. Since slide movement of the sliding member 220 can be allowed when the locking assembly 240 is broken like this, constraint of the door locking part 230 can be released using a handle.
  • FIGs. 5 and 6 are views illustrating a locking device of a door according to another embodiment of the present invention.
  • elements having like and equivalent functions will be denoted by like reference numerals and details thereon will not be repeated.
  • a rotation restricting portion 224 for restricting the rotation direction of the rotating deformation portion 282 so that the rotating deformation portion 282 may rotate only in a direction applying pressure to the safety plate 270 while the safety plate 270 is broken as the rotating deformation portion 282 rotates and applies pressure to the safety plate 270 when a forced shock is applied to the locking member 250.
  • the rotation restricting portion 224 restricts clockwise rotation of the rotating deformation portion 282 and allows only counterclockwise rotation (rotation in a direction applying pressure to the safety plate) of the rotating deformation portion 282, and thus an error that may occur when the rotating deformation portion 282 rotates clockwise can be prevented in advance.
  • the rotation restricting portion 224 may be provided in a variety of methods depending on required conditions and design specifications.
  • the rotation restricting portion 224 may be provided in one piece together with the sliding member 220 which slidingly moves on the inner surface of the door.
  • a rotation restricting portion 224 approximately formed in a "V" shape by partially incising a portion of the sliding member 220 and bending the incised portion to be adjacent to the safety plate 270 will be described as an example. Since the pressing piece 282b may be constrained to the bottom surface of the rotation restricting portion 224 by this structure when the rotating deformation portion 282 rotates clockwise, clockwise rotation of the rotating deformation portion 282 may be prevented in advance.
  • the rotation restricting portion it is possible to separately form the rotation restricting portion and attach the rotation restricting portion to the sliding member in a general method, and alternatively, it is also possible to configure the rotation restricting portion to be connected to another part or portion instead of the sliding member.
  • the shape and the number of the rotation restricting portions 224 may be appropriately changed depending on required conditions and design specifications.
  • a support portion 225 for stably supporting a disposition state of the rotation restricting portion 224 with respect to the sliding member 220 may be provided.
  • the support portion 225 may be provided to support the rotation restricting portion 224 in a variety of methods depending on required conditions and design specifications.
  • an incision groove 223 may be formed at the sliding member 220, and the support portion 225 may be connected to the rotation restricting portion 224 in one piece and supported by one side of the incision groove 223.
  • the rotation restricting portion 224 may stably perform its own function.
  • the gap T1 between the rotation restricting portion 224 and the safety plate 270 may be formed to be relatively smaller than the thickness T2 of the rotating deformation portion 282.
  • an end portion of the rotating deformation portion 282 is prevented in advance from being escaped through the gap between the rotation restricting portion 224 and the safety plate 270.
  • an object in need of protection such as a safe or an automated banking machine may be safely protected.
  • a locking state of a door may be stably maintained even when a forced attack is applied on the side surface of the door. That is, according to the present invention, when a forced shock is applied to the locking member, the rotating deformation portion is rotated and deformed and applies pressure to the safety plate so that the safety plate may be broken, and the auxiliary locking part operates as the safety plate is broken, and thus the locking state of the door may be further stably maintained.
  • a constrained state of the sliding member can be maintained by the auxiliary locking part until the locking member is broken by a forced shock applied from outside, and a time for opening the safe by an intruder can be delayed as long as possible.
  • the present invention when a shock is applied to the locking member, some of the shock is offset since the rotating deformation portion is rotated and deformed, and thus the shock delivered to the locking assembly through the sliding member can be mitigated, and breakage of the locking assembly by the shock can be delayed.
