The door 20 is formed in a quadrangular shape to correspond to the inner surface of the enclosure 10. Therefore, the door 20 is formed to have an upper side, a lower side, a left side and a right side. And the door 20 is hinged to the enclosure (10). The door 20 rotates between the closed position shown in Fig. 1A and the open position shown in Fig. 1B. In the closed position, the interior of the enclosure 10 is blocked by the door 20 so that the interior of the enclosure 10 is closed without being exposed to the outside. In the open position, the interior of the enclosure 10 is exposed to the outside and opened.

The clasp 30 is for locking and unlocking the door 20, and four fasteners 30 are installed in the housing 25 coupled to the door 20. That is, the housing 25 is formed in a quadrangular shape like the door 20, and has an upper side, a lower side, a left side, and a right side, and the four clasps 30 have an upper side, a lower side, It is installed so as to be able to reciprocate linearly with respect to the left side and the right side, respectively, and haunts each side. In addition, the fasteners 30 installed on the upper and lower surfaces of the housing 25 are capable of reciprocating linear movement in the vertical direction, and the clamps 30 provided on the left and right sides of the housing 25 are capable of reciprocating linear movement in the left and right directions. Do. In this way, the movement direction of the two clasps of the four clasps 30 is orthogonal to the movement direction of the remaining two clasps. Each clamp 30 includes three locking members 31, an intermediate member 32 to which the three locking members are respectively fixed, and a pressurized member 33 fixed to the intermediate member. 31), the intermediate member 32 and the pressurized member 33 are formed in one body and reciprocate linearly move in the same direction together. Each locking member 31 is formed to have a circular cross section or a square cross section, each locking member 31 is a reciprocating linear movement through the entrance hole (not shown) formed in the housing 25. The intermediate member 32 and the member to be pressurized 33 are installed inside the housing 25 and are not exposed to the outside.

With the door 20 in the closed position, each catch 30 is capable of reciprocating linear movement between the locking position and the unlocking position. In the locking position shown in FIG. 2, three locking members 31 included in each clamp 30 are respectively inserted into three insertion holes 11 formed in the housing 10 so that the door 20 is locked. . In the unlocking position, the locking members 31 of the respective clamps are separated from the insertion holes 11 to release the locking of the door 20. And the linear movement of each clamp 30 is guided by the guide portion 251 formed on the inner surface of the housing 25.

The pressure rotating body 40 is for driving the four fasteners 30 in a straight line, and is rotatably coupled to the inside of the housing 25. The pressure rotating body 40 is composed of a first pressure rotating member 41 and a second pressure rotating member 42 which are coaxially coupled to each other. The first pressure rotating member 41 includes a circular body portion 411 and a pair of

protrusions

412 and 413 respectively formed to protrude in the vertical direction from the outer circumferential surface of the body portion. The second pressure rotating member 42 includes a circular body portion 421 and a pair of

protrusions

422 and 423 protruding from the outer circumferential surface of the body portion in left and right directions, respectively. The main body 411 and the main body 421 are the same size, and

insertion holes

414 and 424 of the same size are formed through the main body. A pair of coupling grooves 425 are formed in the main body 421, and a pair of coupling protrusions 415 are inserted into the pair of coupling grooves 425 of the main body 411 by an interference fit method. However, the coupling method of the first pressurizing rotary member and the second pressurizing rotary member may be modified in various forms such as a gear engaging structure in addition to the coupling groove and the engaging protrusion, and the first pressurizing rotary member and the second pressurizing rotary member may be separate parts. It may not be manufactured but may be manufactured as a single body. In addition, the main body 411 and the main body 421 are disposed to be in contact with each other in the same size, and thus the

protrusions

412 and 413 formed in the main body and the

protrusions

422 and 423 formed in the main body are not disposed on the same plane. Are placed at different heights. In addition, the protrusions formed on the first pressurizing rotary member 41 and the second pressurizing rotary member 42 are, for convenience, the upper protrusion 412, the lower protrusion 413, and the left side, respectively, based on the protruding direction with respect to the main body and the main body. The protrusion 422 and the right protrusion 423 will be referred to.

The lengths of the upper protrusion 412 and the lower protrusion 413 are the same, but the length of the upper protrusion 412 and the lower protrusion 413 is longer than that of the left protrusion 422 and the right protrusion 423. In addition, the lengths of the left protrusion 422 and the right protrusion 423 are the same.

The pressure rotating body 40 is installed to reciprocally linearly move between the reference position shown in FIG. 13 and the spaced apart position shown in FIG. 16 along the central axis of rotation of the pressure rotating body, and the linear movement of the pressure rotating body 40 is performed. And the rotation drive configuration will be described later with reference to FIGS. 11 to 16.

The connecting means is intended to allow the plurality of clamps 30 to move linearly to the locking position or the unlocking position when the pressure rotating body 40 rotates. In particular, the connecting means allows the plurality of clamps 30 to be driven with a time difference. For example, after the clamps 30 respectively installed on the upper and lower surfaces of the housing 25 operate first, the clamps 30 respectively installed on the left and right sides of the housing 25 also operate together to generate a time difference. Done. The connecting means comprise a plurality of

grooves

51, 52, 53, 54 and a plurality of

inserts

61, 62, 63, 64.

The plurality of

grooves

51, 52, 53, and 54 are recessed in the pressing member 33 of each clamp. Each of the

grooves

51, 52, 53, and 54 is formed to be open toward the pressure rotating body. Each

groove portion

51, 52, 53, 54 has the same shape and size. That is, the widths of the

grooves

51, 52, 53, and 54, that is, the distances between the pair of inner surfaces facing each other and the

insertion portions

61, 62, 63, and 64 inserted therebetween are all the same. In the present embodiment, four

grooves

51, 52, 53, and 54 are formed, and the upper groove 51 and the lower groove 52 are respectively based on positions of the upper side, the lower side, the left side, and the right side of the pressure rotating body 40. ), The left groove 53 and the right groove 54.

The plurality of

insertion portions

61, 62, 63, and 64 are formed to correspond to the plurality of

groove portions

51, 52, 53, and 54, respectively. The four

insertion portions

61, 62, 63, and 64 are composed of a portion of an upper protrusion 412, a lower protrusion 413, a left protrusion 422, and a right protrusion 423, that is, an upper portion. The part 61, the lower insertion part 62, the left insertion part 63, and the right insertion part 64 are indicated. Each

insert

61, 62, 63, 64 is inserted into each

groove

51, 52, 53, 54, as shown in FIG. 2. Therefore, when the pressing rotary body 40 is rotated, each of the

inserts

61, 62, 63, and 64 presses the inner surface of each of the

grooves

51, 52, 53, and 54 so that each clamp 30 is linearly driven. The boundaries of each of the

inserts

61, 62, 63, 64 are shown in phantom for convenience.

On the other hand, the distance of the insert is defined as the distance from the center of rotation of the pressure rotating body 40 to the end of the insert, the length of each

insert

61, 62, 63, 64 is different. Specifically, the distance between the upper inserting portion 61 and the lower inserting portion 62 is the same, but the distance is larger than the distance between the left inserting portion 63 and the right inserting portion 64. Of course, the distance between the left insert 63 and the right insert 64 is the same. As described above, the widths of the

grooves

51, 52, 53, and 54 are the same. Accordingly, the upper insert 61 and the lower insert 62 contact the inner surface of the upper groove 51 and the inner surface of the lower groove 52 at the time of rotation of the pressure rotating body 40, thereby pressing. The clasps 30 respectively disposed above and below are linearly driven. Then, after the clamps 30 arranged on the upper side and the lower side are driven, the left insert 63 and the right insert 64 are formed on the inner surface of the left groove 53 and the inner surface of the right groove 54. The contact presses are respectively driven so that the clamps 30 arranged on the left and right sides are linearly driven. In this way, a time difference occurs between the driving of the upper clamp and the lower clamp and the driving of the left clamp and the right clamp.

Meanwhile, as described above, the left inserting portion 63 and the right inserting portion 64 are disposed at different heights from the upper inserting portion 61 and the lower inserting portion 62. And a lower height than the lower clamp. Therefore, the movement paths of the left clamp and the right clamp do not overlap with the movement paths of the upper clamp and the lower clamp.

And the drive structure for rotating the pressure rotating body 40 in the present embodiment will be described with reference to FIGS.

11 to 16, in the safe 100 of the present embodiment, the linear movement and rotation drive structure of the pressure rotating body 40 is the first rotary drive 70 and the second rotary drive 80 ) Is further provided.

The first rotational drive 70 is rotatably coupled to the fixed plate 26. The first rotary drive member 70 includes a first rotary drive member 71 and a second rotary drive member 72 engaged to rotate together. The first rotary driving member 71 and the second rotary driving member 72 are prevented from being separated from each other by bolts (not shown) coupled to the

respective pivot parts

711 and 721. And the fixing plate 26 is formed in one body with the housing 25 or formed separately from the housing is configured to be fixed to the housing.

The first rotational driving member 71 includes a cylindrical pivot portion 711 and a circular plate portion 712 larger than the diameter of the pivot portion. The pivot portion 711 is formed to protrude a pair of the pressing portion 713. The pair of pressing portions 713 are disposed to form 180 ° in the circumferential direction of the pivot portion 711.

The second rotary drive member 72 includes a pivot portion 721 inserted into the pivot portion 711 of the first rotary drive member, and a circular plate portion 722 larger than the diameter of the pivot portion. The uneven shape is formed on the entire outer circumferential surface of the pivot part 721 of the second rotary drive member, and the uneven shape of the shape corresponding to the uneven shape of the pivot part is formed on the inner circumferential surface of the pivot part of the first rotary drive member. The plate portion 722 of the second rotary drive member is in close contact with the fixed plate 26.

The

pivot parts

711 and 721 of the first rotary driving member and the second rotary driving member are inserted into the insertion holes 414 and 424 of the first and second pressing rotary members, and thus, the first rotary driving member 70. Is coaxially connected with the pressure rotating body (40).

The second rotary driver 80 includes a cylindrical body portion 81 and a pivot portion 82 smaller than the diameter of the main body portion and into which the pivot portion 721 of the second rotary drive member is inserted. The main body 81 is in close contact with the fixed plate 26, and thus the linear movement of the second rotational drive 80 is constrained. The main body portion 81 is formed with a gear portion 811 including a plurality of teeth as a configuration for transmitting power. In addition, the main body 411 of the first pressure rotating member is inserted into the main body, and accordingly, the second rotary driver 80 and the pressure rotating body 40 are coaxially disposed. In addition, the main body 81 is provided with a guide surface 812 facing the plate portion 712 of the first rotational driving member. In addition, the main body 81 is formed with a first guide groove 813 and a second guide groove 814 concave with respect to the guide surface 812. The first guide groove 813 is formed to be open to both sides, that is, to the first pressing member and the second pressing member. The pair of inner surfaces 8121 which face each other in the circumferential direction of the main body portion 81 of the first guide groove portion 813 is composed of a plane inclined with respect to the rotation center axis direction of the second rotary drive body 80. , The inclined directions of the pair of inner surfaces 8131 are opposite to each other. The second guide groove portion 814 is formed to be open to only one side, that is, only toward the first pressure rotating member. Similar to the first guide groove 813, an inclined inner surface 8141 is formed to face the second guide groove 814 in a pair. The inclined inner surface 8141 of the first guide groove portion and the inclined inner surface 8141 of the second guide groove portion each constitute a pressurizing portion that pressurizes the pressurized rotary body 40 when the second rotary drive member 80 rotates. do.

On the other hand, as already described, the insertion hole 414 is formed through the main body portion 411 of the first pressure rotating member. And a pair of the pressing groove 416 is formed in the inner peripheral surface of the insertion hole 414 concave. On the inner surface of each of the pressing grooves 416, a pair of pressing inclined portions 417 and a pair of pressing plane portions 418 are formed. The pair of pressure inclination parts 417 face each other, but the pressing part 713 is disposed between the pair of pressure inclination parts 417. In addition, the pair of pressing plane portions 418 also face each other.

The pressure inclination portion 417 is a portion that is pressed in contact with the pressing portion 713 during the rotation of the first rotary drive 70. The pressure inclined portion 417 is configured in a plane inclined with respect to the linear movement direction of the pressure rotating body 40, that is, the rotation center direction of the pressure rotating body 40. Therefore, not only the rotational driving force for rotating the pressure rotating body 40 but also the linear driving force for linearly moving the pressure rotating body 40 by the external force applied when the pressing part 713 presses the pressure tilting part 417. Generate. If the rotation of the first rotational drive 70 is constrained, only the linear driving force is exerted so that the pressure rotational body 40 linearly moves from the reference position to the spaced apart position. In addition, although the pressure inclination portion 417 is configured as an inclined plane, it is not necessarily limited thereto, and the pressure inclination portion 417 is not limited to the shape as long as it can simultaneously exert the rotation driving force and the linear driving force when the pressure is applied by the pressure portion 713. . For example, the pressure inclination portion may be configured as a convex or concave curved surface with respect to the inclined plane of the present embodiment, or may be configured by combining a convex or concave curved surface and an inclined plane. For reference, FIG. 15 shows a convex curved surface as the pressure inclination portion 417.

The pressing plane portion 418 is directly connected to the end of the pressing slope portion 417. The pressing plane portion 418 is composed of a plane having a normal vector in a direction orthogonal to the linear movement direction of the pressure rotating body 40. Therefore, due to the external force applied when the pressing portion 713 presses the pressing plane portion 418, only the rotation driving force for rotating the pressure rotating body 40 is generated and the linear driving force for linearly moving the pressure rotating body 40. Does not occur.

The upper protrusion 412 and the lower protrusion 413 of the first pressure rotating member are inserted into the first guide groove 813 and the second guide groove 814. Therefore, the inner surface (8131,8141) of the first guide groove portion and the second guide groove portion to press the upper protrusion 412 and the lower protrusion 413, respectively, during the rotation of the second rotary driving member 80, the pressure rotating body also It rotates together in the same direction as the second rotary drive.

The pressure rotating body 40 is linearly movable between a reference position and a spaced position along the rotational center axis of the pressure rotating body. When the pressure rotating body 40 is disposed at the reference position shown in FIG. 13, the pressing part 713 is disposed between the pair of pressing inclination parts 417 as shown in FIG. 14. In this state, when the first rotational drive 70 is rotated, the pressing portion 713 of the first rotational driving body presses the pressure inclination portion 417. However, the upper protrusion 412 and the lower protrusion 413 of the first pressure rotating member are disposed in the first guide groove 813 and the second guide groove 814 of the second rotary drive member, the pressure rotating body 40 As it will be described later is connected to the motor does not rotate. As a result, the pressure rotating body 40 rotates until the upper protrusion 412 and the lower protrusion 413 contact the inner surfaces of the first guide groove 813 and the second guide groove 814, respectively. The rotation of the pressure rotating body 40 is prevented so that the pressure rotating body 40 is linearly moved to the spaced position shown in FIG. 15. In the spaced apart position, the upper protrusion 412 and the lower protrusion 413 of the pressure rotating body are completely separated from the first guide groove 813 and the second guide groove 814 of the second rotary driver. After that, when the first rotational drive 70 continues to rotate, the pressing portion 713 of the first rotational drive presses the pressing plane portion 418 of the pressing rotational body. 70 and the pressure rotating body 40 rotate together. At this time, since the rotation path of the pressure rotating body 40 and the rotation path of the second rotation driving body 80 do not overlap at all, the second rotation driving body 80 does not rotate. In addition, since the pressure rotating body is elastically biased by the elastic member 90 to be described later, the upper protrusion 412 and the lower protrusion 413 remain in contact with the guide surface 812 of the second rotating driver even during rotation. Done.

As such, the upper protrusion 412 and the lower protrusion 413 serve to guide the linear movement of the pressure rotating body 40, in particular, the lower portion of the upper protrusion 412 and the lower protrusion 413, that is, the main body portion Since the portion connected to the 411 and the main body 421 guides the linear movement of the pressure rotating body, the lower portions of the upper protrusion 412 and the lower protrusion 413 are the upper guide protrusion 65 and the lower guide protrusion, respectively. (66). Unlike the present embodiment, however, a pair of guide protrusions may be separately formed on the outer circumferential surface of the main body of the first pressure rotating member, and the guide protrusions may be configured to be disposed in the first guide groove portion and the second guide groove portion, respectively. .

On the other hand, when the pressure rotating body 40 is disposed in the reference position shown in FIG. 13, when the second rotating driving body 80 is rotated, the first guide groove 813 and the second of the second rotating driving body are rotated. The inclined

inner surfaces

8131 and 8141 of the guide groove 814 press the upper guide protrusion 412 and the lower guide protrusion 413 of the first pressure rotating member, respectively. In addition, since no external force is applied to the first rotary driver, the first rotary driver is in a state capable of freely rotating. Thus, when the pressure rotary member 40 is rotated by the second rotary driver 80, Since the pressure inclination part 417 presses the pressure part 713 of the first rotary driver, the second rotary driver 80, the pressure rotary member 40, and the first rotary driver 70 are all Rotate in the same direction.

The pressure rotating body 40 is elastically biased from the spaced apart position to the reference position by the elastic member 90. The elastic member 90 may be any type of compressive coil spring, compression coil spring, and rubber, so long as the elastic member 90 exhibits restoring force during compression or stretching. Both ends of the compression coil spring 90 are in contact with and supported by the plate portion 712 of the first rotary driving member and the main body 421 of the second pressing rotary member of the pressure rotating body 40, respectively.

As described above, the first rotary driving member 70 may rotate relative to the pressure rotating body 40 when the pressure rotating body 40 linearly moves from the reference position to the spaced apart position, and the pressure rotating body 40 is spaced apart. In the state arranged in position, it does not rotate relative to a pressurized rotor. Here, the relative rotation angle range of the first rotary drive 70 is the degree of inclination of the pressure inclined portion 417, the upper insertion portion 61 and the lower insertion portion 62 and the upper groove portion 51 and the lower groove portion 52 It can be set by various factors, such as the clearance between. On the other hand, the second rotary drive 80 is also relatively rotatable with respect to the pressure rotating body 40 according to the position of the pressure rotating body 40. That is, when the pressure rotating body 40 is disposed in the spaced apart position, the second rotary driving body 80 rotates relative to the pressure rotating body 40, but when the pressure rotating body 40 is disposed in the reference position, The rotary drive 80 can only rotate with the pressure rotating body (40).

In addition, the vault 100 of the present embodiment is configured to rotate the first rotary drive 70 and the second rotary drive 80, the key bundle 21, the motor, and the user authentication unit 22 Equipped.

The key bundle 21 is rotatably coupled to the door 20. As shown in FIG. 1, a key hole 211 exposed to the outdoor side of the door is formed on the outer surface of the key bundle 21, and a key having a shape corresponding to the shape of the key hole is inserted into the key hole 211. When rotated, the key bundle 21 rotates with the key. The key bundle 21 is coupled to interlock with the first rotational drive 70, and this linkage is inserted into one end of the coupling hole 723 and the coupling hole formed in the plate portion 722 of the second rotational drive member. The end is made by a shaft (not shown) connected to the key bundle 21. That is, the shaft also rotates when the key bundle 21 rotates, and accordingly rotates the second rotary drive member 72 pressed by the shaft. The first rotational drive 70 is driven using a key in an emergency such as a failure of a user authentication unit or a motor.

The motor (not shown) is operated by a power source, and a rack gear coupled to the gear unit 811 of the second rotary drive member and a reduction gear for reducing the rotational force of the motor are connected to the output shaft of the motor. Therefore, when the motor is operating, the second rotary driver 80 is driven. On the other hand, when a solenoid is installed instead of a motor, a power transmission means for converting the linear driving force of the solenoid into the rotational force of the second rotary drive is required, and the power transmission means includes a gear or a link, but such a configuration Since the description is only a matter of ordinary skill in the art, a detailed description thereof will be omitted.

The user authentication unit 22 is for authenticating a user, and includes a keypad for inputting numbers, letters, or symbols, and a biometric information recognizer for recognizing biometric information of a user, such as a fingerprint or an iris. When the user is authenticated through the user authentication unit 22, a control signal for operating the motor is output, and the motor is operated.

In the safe 100 configured as described above, when the motor is normally operated using the user authentication unit 22, the second rotary driver 80 rotates, and thus, the first rotary driver 70 and the pressurized body. The rotating body 40 can be rotated all. As the pressure rotating body 40 rotates as described above, the upper inserting portion 61 and the lower inserting portion 62 of the first pressing rotating member press the inner surfaces of the upper groove 51 and the lower groove 52, respectively. Thus, the upper catch and the lower catch are driven first. And a little later, the left inserting portion 63 and the right inserting portion 64 of the second pressure rotating member press the inner surfaces of the left groove portion 53 and the right groove portion 54, respectively, so that the left clamp and the right clamp are Driven. In other words, the upper clamp and the lower clamp are initially driven, and after a certain time, the left clamp and the right clamp are also driven together with the upper clamp and the lower clamp.

As such, in the present embodiment, the four clamps are not operated at the same time, but the four clamps are configured to operate after the two clamps are operated first, thereby preventing the output and power consumption of the motor from excessively rising. In addition, durability is improved and energy consumption can be reduced. In particular, since the four clasps do not work all at once but operate sequentially with time difference, the starting load can be greatly reduced. Due to the reduction of the starting load, a reduction gear having a lower reduction ratio than the conventional one may be used.

Then, in an emergency such as when the battery for operating the motor is discharged, the user authentication unit is broken, or the password is forgotten, the predetermined key is inserted into the key hole 211 to be rotated. When the key is rotated in this way, the first rotational drive 70 can be rotated in conjunction with the key rotation. At this time, since the pair of pressing portions 713 of the first rotary driving member presses the pressure inclined portion 417 of the first pressing rotary member, the pressing rotary body 40 is moved from the reference position shown in FIG. It linearly moves to the separation position shown in FIG. Then, after that, the pressure rotating body 40 rotates while the upper guide protrusion 65 and the lower guide protrusion 66 contact with the guide surface 812 of the second rotary drive body. Therefore, the second rotary drive 80 does not rotate, only the first rotary drive 70 and the pressure rotary body 40 is rotated so that the four clamps are driven with a time difference as described above.

In the drawings of this embodiment, a line indicating a boundary between the upper protrusion and the upper pressing portion and a line indicating the boundary between the upper protrusion and the upper guide protrusion are shown for convenience of description.

Meanwhile, in the present embodiment, the length of the insertion part is different and the width of the groove part is configured to be the same. However, as shown in FIG. 4, the lengths of the insertion holes are all the same, and the width of the groove part may be different.

Referring to FIG. 4, in the safe of the present embodiment, the lengths of the upper protrusion 412a, the lower protrusion 413a, the left protrusion 422a, and the right protrusion 423a of the first pressure rotating body 40a are all the same. Do. The distance between the upper insertion portion 61a, the lower insertion portion 62a, the left insertion portion 63a, and the right insertion portion 64a is also the same. The width of the upper groove 51a and the lower groove 52a is smaller than the width of the left groove 53a and the right groove 54a. Therefore, the upper inserting portion 61a and the lower inserting portion 62a contact and press the inner surface of the upper groove portion 51a and the inner surface of the lower groove portion 52a, respectively, during the rotation of the pressure rotating body 40a. The left insert 63a and the right insert 64a contact and press the inner surface of the left groove 53a and the inner surface of the right groove 54a, respectively. A time difference occurs between the linear movement of the clamp and the right clamp.

And in the above embodiments, the groove portion and the insertion portion are configured to be formed in the pressing member and the pressing rotary body of the clamp, respectively, as shown in FIG. It may be configured to be formed.

Referring to FIG. 5, in the safe of the present embodiment, the upper protrusion 412b of the first pressing rotary member is formed to be recessed upwardly to have an upper groove 51b recessed toward the center of the first pressing rotary member. In addition, the upper groove portion is not formed in the pressing member 33b of the clasp disposed above, as shown in the previous embodiment, and instead, the upper insertion portion 61b is formed to protrude toward the pressing rotating body. The upper insertion portion 61b is inserted into the upper groove portion 51b. Therefore, when the pressure rotating body is rotated, the inner surface of the upper groove portion 51b presses the upper insertion portion 61b, so that the upper clamp can be driven linearly. Of course, each clasp is driven with time difference, which is the same as already described. In addition, the upper pressing portion may not be formed in the first pressing rotating member, and the upper groove may be configured to be directly formed in the main body of the first pressing rotating member.

On the other hand, the time difference actuation structure of the clasp may be configured as shown in Figure 6 unlike the previous embodiments.

The upper protrusion 412, the lower protrusion 413, and the left protrusion 422c and the right protrusion 423c of the second pressure rotating member have the same length. The upper protrusion 412 and the lower protrusion 413 are formed with an upper press portion 61 and a lower press portion 62 as in the embodiment shown in FIG. 2. In addition, in the pressurized member 33 disposed above and below, the upper groove portion 51 and the lower groove portion 52 are formed to open toward the upper press portion and the lower press portion, as shown in FIG. 2. The upper insertion portion 61 and the lower insertion portion 62 are inserted into the upper groove portion 51 and the lower groove portion 52, respectively, and are formed to be spaced apart from the inner surfaces of the upper groove portion 51 and the lower groove portion 52 by a predetermined distance. do. Accordingly, when the pressure rotating body 40c is rotated, the time of rotation of the pressure rotating body 40c and the upper inserting portion 61 and the lower inserting portion 62 contact the inner surfaces of the upper groove 51 and the lower groove 52. A time difference occurs between the time points.

On the left protrusion 422c and the right protrusion 423c, the left groove 53c and the right groove 54c are formed, respectively. In particular, unlike the previous embodiment, the left protrusion 422c and the right protrusion 423c are formed to have long holes in the longitudinal direction of each of the

protrusions

422c and 423c. . In addition, the left inserting portion 63c and the right inserting portion 64c protrude from the pressurized members 33 disposed on the left and right sides, respectively. Each of the

inserts

63c and 64c is formed to protrude in the thickness direction of the door 20, the cross section of which is circular. The left insert 63 and the right insert 64 are inserted into the left long hole 53c and the right long hole 54c, respectively. And the left insertion portion 63c is inserted into contact with a pair of inner surfaces of the left long hole 53c facing each other so that the locking clasp moves linearly at the same time as the rotation of the pressing rotor 40c, the pressing rotor 40c and the clamp There is no time difference between the operations of. Similarly to the left inserting portion, the right inserting portion 63c is inserted into contact with a pair of inner surfaces of the right long hole 54c facing each other.

In the safe configured as described above, the inner surfaces of the left long hole 53c and the right long hole 54c simultaneously press the left insert 63c and the right insert 64c at the same time as the rotation 40c of the pressure rotating body. However, the upper insertion part 61 and the lower insertion part 62 do not pressurize the inner surfaces of the upper groove part 51 and the lower groove part 52. Therefore, when the pressure rotating body 40c rotates, the left clamp and the right clamp are operated first, and after a predetermined time, the upper clamp and the lower clamp are operated. Thus, in this embodiment, the upper clamp and the lower clamp are operated with a time difference from the left clamp and the right clamp.

Moreover, in the safe of this embodiment, the effect which a shock and a noise are prevented is acquired. That is, in the safe of FIG. 2, for example, the left insertion part is disposed inside the left groove part, and thus there is play. Therefore, the inner surface of the left groove part hits the left insertion part by gravity in the course of operation. have. However, when the left insertion portion and the right insertion portion are completely inserted into the left and right holes as in the present embodiment, the play does not exist, thereby preventing shock or noise.

On the other hand, Figure 7 to Figure 10 shows an example of a safe with improved security against physical hacking using a hacking tool such as paru. In the safe according to the present embodiment, the time difference actuation structure of the clasp is the same as the structure of the previous embodiment, and a description thereof will be omitted.

7 to 10, in the safe of the present embodiment, a locking groove 311 is formed in the left clamp. Specifically, the locking groove 311 is formed in the two locking members 31d of the three locking members included in the left lock, and the locking groove 31 is not formed in the other locking member 31. For convenience, the pair of locking members in which the locking grooves are formed is referred to as an upper locking member and a lower locking member, and the locking member in which the locking grooves are not formed is referred to as an intermediate locking member. In addition, the upper locking member 31d, the lower locking member 31d, and the intermediate locking member 31 have the same cross-sectional shape as a whole and have the same shape and size except for a portion where the locking groove is formed.

Each of the locking grooves 31 may be formed in plural on one of the surfaces of the locking member 31d toward the outside of the door, that is, on the outdoor side, but is formed as shown in FIG. 7 in this embodiment. Each of the locking grooves 31 is formed to be concave on the outdoor surface and extends to the upper and lower ends of the locking members 31d. A locking protrusion 111 is formed in each of the insertion holes 11d into which the upper locking member 31d and the lower locking member 31d are inserted. Each locking protrusion 111 is formed to protrude with respect to the inner surface of each insertion hole (11d), and in normal times without physical hacking is spaced apart from the linear movement path of each locking member (31d) to perform a linear movement of each lock Do not disturb However, in the insertion hole 11 into which the intermediate locking member 31 and the intermediate locking member are inserted, as shown in FIG. 8B, the locking groove and the locking protrusion are not formed, respectively.

On the other hand, FIGS. 7 to 10 show only the locking member and the corresponding insertion hole included in the left clamp for the sake of simplicity of the drawings. Only the description thereof is described above, but the upper clamp, the lower clamp, and the right clamp are also shown. The left clasp may be configured in the same structure, and a description and illustration thereof will be omitted herein. In the locking position where the locking

members

31 and 31d are inserted into the insertion holes 11 and 11d, the locking latch is further inserted, which is implemented by a separate stopper means. Since the stopper means is already widely known, a detailed description thereof will be omitted here.

Hereinafter, in the safe configured as described above, a mechanism for improving the security of the safe in the physical hacking city will be described.

Physical hacking attempts to destroy the safe by flipping the door 20 after inserting a so-called 'Paru' into a gap between the door 20 and the enclosure 10 have been made. For reference, 'Paru' refers to a tool made of a metal material and formed long in one direction and having a groove formed at an end thereof to remove a nail.

The hacker first inserts the gap 1 into the gap between the door and the housing as shown in FIG. 9A and then flips the par 1 back and forth in the direction of the arrow. When the par 1 is retracted as described above, the door 20 is further pressed by the par 1 compared to the enclosure 10 so that the door 20 moves in a direction away from the enclosure and the door 20 and the enclosure. Since the gaps between the 10 are further widened, the housing 25 fixed to the door 20 also moves as shown in FIG. 9B. Of course, in some cases the door may be distorted. At this time, the door 20 is rotated to a certain degree as shown in (b) of FIG. For reference, the physical hack is not completed by flipping the par once, but generally by flipping several times to complete a wide gap between the door 20 and the enclosure 10.

As such, when the housing 25 moves together with the door 20 by physical hacking, the housing 25 also moves in the same direction as the door 20. In the process of moving the housing, as shown in FIG. 10, since the locking protrusion 111 is caught by the locking groove 311, the locking key is retracted, that is, the upper locking member 31d and the lower locking member 31d are locked. Resistance is made without moving in the direction away from the insertion hole 11d. In this way, when the left stopper resists, the door 20 is forcibly unlocked and not opened, thereby greatly improving the security against physical hacking of the safe. In addition, the deformation of the locking member and the damage of the safe is effectively prevented and the durability of the safe is greatly improved.

In addition, in the present embodiment, the locking groove and the locking protrusion are formed only in the upper locking member and the lower locking member and the insertion hole corresponding thereto, and the locking groove and the locking protrusion are not formed in the intermediate locking member and the corresponding insertion hole. In the absence of physical hacking, it is possible to prevent the phenomenon that the locking projection is not smoothly made due to the locking projection being caught in the locking groove at normal times. In particular, this effect is more effectively achieved by increasing the thickness of the intermediate locking member or reducing the size of the insertion hole into which the intermediate locking member is inserted. For example, the clamp may operate slightly out of its original operating position due to manufacturing tolerances or wear due to use, but even in this case, the surface of the intermediate locking member is inserted into the insertion hole before the locking protrusion is inserted into the locking groove. This is because the locking protrusion and the locking groove are not caught in contact with the side surface.

On the other hand, in the embodiment shown in Figure 7 to 10 is configured to be formed in the locking groove and the locking projections respectively the locking member and the insertion hole, on the contrary, the locking groove is formed concave in the inner surface of the insertion hole and the locking projection is locked It may be configured to protrude to the outer side of the member. In addition, in the present embodiment, the locking protrusion is configured not to be formed in the intermediate locking member, but the locking protrusion may be formed in the intermediate locking member.

As mentioned above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the technical idea of the present invention. It is obvious.

For example, in each of the foregoing embodiments, the clamp is configured to move in a straight line, but the clamp may rotate to be inserted into and removed from the insertion hole, and in some cases, the clamp may be configured to perform both linear movement and rotational movement. have.
