The enclosure 10 is formed in a rectangular box shape as a whole. On the bottom surface of the enclosure 10, four supporters on which the enclosure 10 is supported, for example, are supported on an office floor or a home floor, are provided with four levelers 11 which can be adjusted in height. The four levelers 11 are disposed at four corners of the enclosure 10, respectively, and have a well-known screw structure for adjusting the upper and lower levels by using screws, and thus detailed description thereof will be omitted. In addition, the interior of the enclosure 10 is formed to open to the front. And a plurality of insertion holes (not shown) are formed on the inner surface of the enclosure 10 as described in the prior art. Specifically, the inner surface of the housing 10 includes an upper inner surface, a lower inner surface, a left inner surface and a right inner surface, and each of the inner surface is formed with three insertion holes (not shown).

The front surface of the enclosure 10 is formed stepped as shown in FIG. This stepped portion is disposed around the opening of the enclosure 10. A pair of sliding holes 102 are formed in the stepped portion of the enclosure 10. The pair of sliding holes 102 are formed to have the same shape and size, and are spaced apart from each other in the vertical direction.

The slide hinge unit interconnects the enclosure 10 and the door 30 and includes a sliding member 21 and a hinge shaft 22.

The sliding member 21 is provided with a pair to correspond to the number of the sliding holes (102). Each slide member 21 is slidably inserted into each sliding hole 102. Sliding member 21 is seen as a whole "b" form when viewed from the top. That is, the sliding member 21 includes a portion inserted into the sliding hole 102 and a portion protruding without being inserted into the sliding hole 102, and the inserted portion and the protruding portion form an angle of 90 degrees to each other. And the height and width of the portion inserted into the sliding hole 102 of the sliding member 21 is preferably formed to be smaller than the height and width of the sliding hole 102, which is the sliding member 21 in the sliding direction This is because only linear movement can be performed, resulting in excellent operability.

The sliding member 21 is slidable in the direction in which the sliding hole 102 is inserted and detached, and in particular, the sliding member 21 is slidable between the positions shown in FIG. 3 from the positions shown in FIG. 2. The sliding member 21 can no longer be protruded at the maximum protruding position shown by the phantom line in FIG. 3, and this protruding prevention is a protrusion protruding from the upper side of the sliding member 21 at the position shown in FIG. 5B. 211 may be achieved by engaging the stepped stepped surface 103 on the upper inner surface of the sliding hole 102, and may also be implemented by various other known configurations, which will be apparent to those skilled in the art. In addition, since it is not the main configuration of the present invention, a detailed description thereof will be omitted.

The hinge shaft 22 is fixed to an end portion of the sliding member 21 that is not inserted into the sliding hole. Therefore, the hinge shaft 22 is spaced apart from the center axis of the sliding hole to the outside of the enclosure. The hinge shaft 22 is formed in the shape of a rod of a circular cross section formed long in the vertical direction. The hinge shaft 22 may be fixed to the sliding member 21 by welding or the like, and in some cases, the hinge shaft 22 may be manufactured as a body with the sliding member 21.

The door 30 is formed in a quadrangular shape as a whole to correspond to the inner side surface of the enclosure 10. Therefore, the door 30 is formed to have four sides, namely, an upper side, a lower side, a left side, and a right side, like the enclosure. And, the inner surface of the door 30 is formed stepped to correspond to the stepped portion of the housing. Therefore, when the door 30 is disposed in the closed position shown in FIG. 4, the stepped portion of the inner surface of the door 30 and the stepped portion of the inner surface of the housing are engaged with each other.

The door 30 is coupled to the enclosure 10 and operates to open and close the interior of the enclosure 10. The door 30 has a reciprocating linear motion and a reciprocating rotational motion. That is, the door 30 reciprocates linearly between the closed position and the intermediate position, and reciprocally rotates between the intermediate position and the open position. In the closed position shown in FIG. 2, the interior of the enclosure 10 is completely covered by the door 30 so that the interior of the enclosure 10 is closed. If the door 30 is linearly moved forward from the closed position to an intermediate position shown in phantom in FIG. 3, access to the interior of the enclosure 10 is possible from the side of the enclosure 10, but the enclosure ( Not possible from the front of 10). And when the enclosure 10 rotates counterclockwise around the hinge axis 22 in the intermediate position, since the interior of the enclosure is disposed in the fully open front position, the user inside the enclosure 10 in the open position It will put or take things out.

And the door 30 is coupled to the handle 31 that the user grabs.

The locking unit is for locking and releasing the door 30 in a state where the door 30 is disposed in the closed position. The locking unit is composed of three left fasteners 41 and three right fasteners 41 that are capable of reciprocating linear movement in the horizontal direction. The three left clamps and the three right clamps operate to be inserted into and separated from three insertion holes (not shown) respectively formed on the left inner side and the right inner side of the enclosure 10, respectively. In addition, the locking unit is not shown, but also includes three upper fasteners and three lower fasteners that can be reciprocated linearly in the vertical direction to be inserted into and separated from the three insertion holes formed on the upper inner side and the lower inner side of the enclosure 10. It is configured to. In addition, a keypad 42 for authenticating a user, a motor (not shown) for activating each clasp when the user is authenticated, and a key bundle 43 for manually operating the clasp using a key are also provided.

When the link unit rotates toward the open position in a state in which the door 30 is not slid to an intermediate position, the door unit is automatically moved to the intermediate position shown by the virtual line in FIG. 3 by the rotation of the door 30 without any power. It is to be sliding to. The link unit is provided in pairs to correspond to the number of slide back hinge units, and includes a first link 51 and a second link 52, respectively.

The first link 51 has a plate shape. Circular first disc portions 511 and second disc portions 512 are formed at both ends of the first link 51, respectively, and the first disc portion 511 and the second disc portion 512 are connected to each other. Connected by). The first disc portion 511 is hinged to a portion of the sliding member 21 that is not inserted into the sliding hole. That is, the first disc part 511 is rotatably inserted into the hinge pin 212 protruding from the sliding member 21. In addition, the pressure portion 514 is formed to protrude from the first disc portion 511.

Similarly to the first link 51, the second link 52 is formed in a plate shape, and includes a first disc part 521 and a second disc part 522 and a first disc part 521 which are formed in a circular shape at both ends. ) And a connecting portion 523 interconnecting the second disc portion 522. The first disc portion 521 is hinged to the enclosure 10, in particular rotatably inserted into the hinge pin 104 protruding from the enclosure.

The first link 51 and the second link 52 are hinged to each other. That is, the pin member 53 is inserted into each of the second disc portion 512 of the first link and the second disc portion 522 of the second link. Therefore, the first link 51 and the second link 52 can be rotated relative to the pin member 53, respectively.

As such, the first link 51 and the second link 52 are configured, and the link angle θ formed by the first link 51 and the second link 52 depends on the sliding of the door 30. But gradually increases from the closed position shown in FIG. 2 to the intermediate position shown by the phantom line in FIG. 3. Here, the link angle refers to an angle formed between the hinge coupling portions of the first link 51 and the second link 52, that is, the pin member 53, with respect to the first link 51 and the second link 52.

The hinge member 60 is provided in pair to correspond to the number of the slide hinge units 20. The pair of hinge members 60 are fixed to the door 30 to rotate and linearly move together with the door 30. Each hinge member 60 includes a main body portion 61 and a pressing portion 62.

The main body portion 61 is inserted into the hinge shaft 22 of the slide hinge unit and is rotatable about the hinge shaft 22. The main body portion 61 has an insertion groove portion 611 formed in a concave shape, in particular toward the pressure portion so that the pressure portion 514 of the first link disposed at the reaction force acting position shown by the solid line in FIG. 3 can be inserted. It is formed concave. Here, the reaction force acting position refers to a position in which the door 30 is disposed before the intermediate position is slid by a preset reference distance from the closed position, and the pressing portion 514 of the first link when the hinge member 60 is rotated. Refers to the first position that can be pressed by contact by the pressing portion 62 of the hinge member, the position shown by the solid line in FIG. The reaction force acting position is a position where the door 30 may automatically slide to the intermediate position at the same time as the door rotates even when the door 30 does not reach the intermediate position shown by the virtual line in FIG. 3. If the pressurized portion 514 of the link is disposed inside the insertion groove 611 of the main body portion, the door 30 is disposed in the repulsive action position.

The pressing portion 62 is composed of one inner side surface of the insertion groove 611. The pressing part 62 pressurizes the pressurized part 514 of the first link 51 disposed at the reaction force acting position when the hinge member 60 rotates, as shown in FIG. 4, and rotates as shown in FIG. 4. In the door automatically slides to the intermediate position of FIG.

On the other hand, in the intermediate position where the door 30 protrudes to the maximum from the closed position, even if the hinge member 60 rotates toward the open position, the pressing portion 62 of the hinge member pressurizes the pressure portion 514 of the first link. can not do. The hinge member 60 is configured to rotate only to an open position, but the pressing member 514 of the first link is not disposed on the rotation path of the hinge member 60.

The hinge member 60 is fixed to the main hinge member 70 and rotates together with the main hinge member 70. The main hinge member 70 is fixed to the door 30 and is rotatably inserted into the hinge shaft 22. The hinge member 60 may be coupled to the main hinge member 70 and behave as one body by welding. However, the hinge member 60 and the main hinge member 70 may be manufactured as one component.

On the other hand, since the door 30 is heavy because it is configured to include a refractory material and metal, it is preferable that a configuration for guiding the sliding of the door 30 is further provided. As such a further configuration, in this embodiment, the guide groove portion 105 and the pair of rolling support elements 34 slidable to the guide groove portion 105 formed on the left inner side of the enclosure 10 are included.

The guide groove 105 is formed in the sliding direction of the sliding member 21 on the inner side of the left side of the housing 10, that is, elongated forward. The rolling support element 34 is rotatably coupled to the left side of the door 30 and in this embodiment consists of a roller. And rolling support element 34 rotates in contact with the inner surface of the guide groove 105, thereby guiding the sliding movement of the door (30). In addition, in order to guide the sliding of the door, an additional rolling support element (not shown) forming a plane symmetry with the rolling support element 34 is installed on the bottom surface of the sliding member 21 to be in contact with the bottom surface of the sliding hole 102. You can also do that. In addition, the rolling support element 34 may be installed on the bottom surface of the portion to be inserted into the enclosure, not the left side of the door, the rolling support element 34 may be formed of a ball, not a roller.

Hereinafter, an example of an operation process of the storage box 100 configured as described above will be described.

As shown in FIG. 2, in order to access the interior of the enclosure 10 in a state in which the door 30 is disposed in the closed position, first, each clamp 41 is operated by user authentication to be separated from each insertion hole. . Thereafter, the handle 31 may be grasped and pulled so that the door 30 is linearly moved forward to be disposed at an intermediate position shown by a virtual line in FIG. 3. In the linear movement of the door 30, the first link 51 and the second link 52 rotate to increase the link angle θ. As described above, when the door is rotated in the state in which the door 30 is disposed at the intermediate position, the door can be rotated to the open position of FIG. 4. In the rotation process of the door, the hinge member 60 rotates together with the door, but since the pressurized part 514 of the first link is not disposed on the rotation path of the pressing part 62 of the hinge member, the first link The pressurized portion 514 is not pressed by the pressing portion 62 of the hinge member.

On the other hand, when the door 30 is linearly moved to the reaction force acting position shown in FIG. 3, the first link 51 and the second link 52 rotate to increase the link angle θ as described above. Then, when the door 30 is rotated to the open position in the reaction force acting position, the pressing portion 62 of the hinge member presses the pressure portion 514 of the first link to rotate the first link 51. In the process, the link angle is increased more than before the pressurized portion 514 of the first link is pressed. When the link angle θ is increased in this way, the door 30 is forced by the link unit to automatically move linearly in a direction away from the enclosure 10. Therefore, the door 30 is linearly moved at the same time as it is rotated and finally placed in the open position shown in FIG.

In order to close the opened door 30 again, grasping the handle 31 and applying a force to the door so that the door 30 rotates clockwise, the door is rotated clockwise, that is, the door rotates clockwise. Later, it moves straight back to the closed position shown in FIG. At this time, the link angle is reduced.

As described above, since the door 30 is configured to sequentially perform linear movement and rotational movement, the clasp 41 can be installed deeper in the housing 10 than in the prior art. If the clasp 41 is installed deeper in this way, it is possible to greatly improve the security against physical hacking from the outside of the enclosure, in particular, physical hacking through the gap between the door and the enclosure.

In addition, even when the door 30 is not disposed to the intermediate position, even when the door is disposed only to the reaction force acting position, when the door is rotated, the pressurized portion 514 of the first link is driven by the pressing portion 62 of the hinge member. Since the pressure is increased by the link angle, the door 30 is automatically slid to the intermediate position by the force from the link unit. Therefore, the door 30 can be opened to the open position even without sliding the door to the intermediate position. In particular, it is not easy to accurately position the door in the middle position, and when the door is pulled out, the door is frequently placed in the middle position, so that the door is frequently retracted to some extent by contact with various components. As in the example, when the door is configured to protrude to a certain degree during the rotation process, the operability and ease of use can be greatly improved.

Meanwhile, in the present embodiment, the sliding movement between the closed position and the spaced position of the door is manually configured, but the sliding movement of the door may be automatically performed by using the rotational force of the motor. For example, a rack gear is formed in the sliding member along the sliding direction, and the pinion gear-coupled to the rack gear can be configured to operate by a motor. Of course, it is preferable that the reduction gear is coupled between the rack gear and the pinion gear. And it is natural that the rack gear can be configured to be formed in the door.

Meanwhile, in the present embodiment, the first link is configured to rotate only. However, as shown in FIGS. 6 to 8, the first link may be configured to linearly move in the vertical direction.

6 to 8, in the safe 100a of the present embodiment, the base member 80 is fixed to the sliding member 21. The base member 80 includes a cylinder portion 81 having a cylindrical shape as a whole, and a rod-shaped hinge portion 82 coaxially connected to the cylinder portion 81. The pressing surface 811 is formed on the upper surface of the cylinder portion 81. The pressing surface 811 is configured as an inclined surface inclined with respect to the vertical direction, the inclination degree is formed to gradually increase along the circumferential direction of the hinge portion 82. The width of the inclined surface is constant and is formed in a spiral form. However, the pressing surface 811 may be configured not as an inclined surface but a convex or concave curved surface with respect to the inclined surface.

The first disc portion 511a of the first link 51a is rotatably inserted into the hinge portion 82 of the base member. In addition, a pressurized surface 5111 is formed on the first disc portion 511a of the first link 51a so as to face the pressing surface 811 of the cylinder portion in the vertical direction and to be in contact with each other. Similarly to the pressing surface 811, the surface to be pressed 5111 is formed of an inclined surface, and the inclined degree is formed to gradually increase along the circumferential direction of the hinge portion 82. The width of the inclined surface is constant and is formed in a spiral form. The press surface 5111 is disposed coaxially with the press surface 811. In addition, it is preferable that the degree to which the to-be-pressed surface 5111 and the pressing surface 811 incline is formed the same.

The first link 51a is linearly movable between the separation position shown in (a) of FIG. 8 and the pressing position shown in (b) of FIG. 8. The spaced apart position refers to the position of the first link 51a when the door is disposed in the closed position. In the spaced apart position, the pressurized portion 514 of the first link is spaced apart from the rotation path of the pressing portion 62 of the hinge member. As a result, even when the hinge member 60 is rotated, the first link 51a is not pressed. Therefore, the link angle does not change. On the other hand, in the pressing position, since the pressurized portion 514 of the first link is disposed on the rotation path of the pressing portion 62 of the hinge member, the pressing portion 62 of the hinge member is rotated when the hinge member 60 is rotated. The pressurized portion 514 of one link is pressed. Therefore, it is possible to increase the link angle, thereby automatically moving the door 30 in a direction away from the enclosure (10).

The linear movement from the spaced position of the first link 51a to the pressurized position is not driven by a separate driving means, but is driven by sliding of the door 30. That is, when the door slides from the closed position, as the link angle increases, the first link 51a also rotates. In the rotation process of the first link 51a, the press surface 5111 of the first link is pressed by the press surface 811 while being in contact with the press surface 811 of the base member, and thus, the first link 51a. ) Rotates automatically and linearly moves to pressurized position at the same time.

In addition, when the first link 51a linearly moves from the spaced position to the pressing position, it is preferable that both the first disc portion 511a and the second disc portion 512 of the first link linearly move by the same distance in the same direction. When the linear movement is performed in this way, the pin member 53 serves to guide the linear movement of the second disc portion 512 of the first link. However, the second disc part 512 of the first link 51a may be constrained so as not to linearly move in the same direction as the first disc part 511a of the first link. 53 is loosely inserted into the second disc portion 512 of the first link, so that when the linear movement of the first disc portion 511a of the first link to the pressing position is performed, the second disc portion 512 of the first link It may be configured to rotate about a pin member 53 to a certain degree.

In order to automatically return the first link 51a to the spaced position, the elastic member 90 is preferably provided. Elastic member 90 is composed of a compression coil spring is inserted into the hinge portion (82). One end of the compression coil spring is in contact with the first disc portion 511a of the first link, and the other end of the compression coil spring is in contact with the support member 91. The support member 91 is fixed to the door 30 by bolting, welding, or the like, and is formed in a circular plate shape like the first disc portion 511a of the first link. As shown in FIG. 8B, the compression coil spring is compressed compared to FIG. 8A when the first link 51a moves to the pressurized position, so that the compression coil spring is compressed to the first disc portion 511a of the first link. Apply elastic force.

In the safe 100a configured as described above, when the door 30 is linearly moved from the closed position to the reaction force acting position, the first link 51a is shown in FIG. 6 as the link angle θ gradually increases. It rotates clockwise based on the state. When the first link 51a is rotated, the pressurized surface 5111 of the first link is pressed by the pressing surface 811 of the base member so that the first link 51a is linearly moved upward. For example, the pressing position shown in (b) of FIG. 8 is reached. In this way, when the first link 51a reaches the pressing position, the door 30 does not reach the intermediate position. Afterwards, when rotating in the counterclockwise direction to open the door, the pressing portion 62 of the hinge member presses the pressurized portion 514 of the first link, so that the link angle is further increased. The force is received by the link unit to move away from the enclosure. As a result, the door is linearly moved at the same time as the door rotates in the open position. Therefore, even if the user does not slide the door 30 to the intermediate position, the user can perfectly position the door 30 to the open position even after the door 30 is rotated only after the reaction force is slid.

Meanwhile, in the first and second embodiments, the pressing portion of the hinge member is configured to press the pressurized portion of the first link, but as shown in FIG. 9, the pinion gear portion of the hinge member and the pinion gear of the first link are shown. Depending on the position of the additional door may be configured to be geared or not geared to each other.

Referring to FIG. 9, in the safe 100b of the present embodiment, a pinion gear portion 612 including a plurality of teeth is formed on the entire circumference of the main body portion 61b of the hinge member 60b. The pinion gear portion 5112 including a plurality of teeth is also formed in the first disc portion 511b of the first link 51b. However, the pinion gear portion 5112 of the first link 51b is not formed in the entire circumference of the first disc portion 511b but is formed only in a portion thereof.

The pinion gear portion 612 of the hinge member and the pinion gear portion 5112 of the first link are selectively geared according to the position of the door. That is, in the state where the door 30 is disposed between the closed position and the reaction force acting position, the pinion gear portion 612 of the hinge member is spaced apart from the pinion gear portion 5112 of the first link even when the door is rotated. Not interlocking That is, even if the hinge member 60b is rotated together with the door by rotating the door 30, the pinion gear portion 612 of the hinge member does not engage with the pinion gear portion 5112 of the first link. Therefore, even if the door is rotated, the link angle does not change, and thus the door rotates without linear movement.

On the other hand, when the door is rotated in the state where the door 30 is disposed at the reaction force action position, the pinion gear portion 612 of the hinge member is engaged with the pinion gear portion 5112 of the first link, so that the first link 51b is used. Rotates and the link angle gradually increases. As the link angle increases, the door 30 automatically moves linearly away from the enclosure. Therefore, the door is linearly moved at the same time as it is rotated so that the door can be finally placed in the open position.

On the other hand, unlike the previous embodiments, even if the link unit is not provided, the same effect can be obtained by simply configuring the device as shown in FIGS. 10 to 12.

10 to 12, in the safe 100c of the present embodiment, the sliding member 21c is formed to be long only in the sliding direction to have an overall "l" shape. In addition, the installation member 213 is formed in the sliding member 21c to open to the front and both side surfaces of the sliding member. Of course, the hinge shaft 22 is fixed to the front surface of the sliding member 21c.

And the pressurized part 106 is formed in the inner surface of the sliding hole 102c of the enclosure. The to-be-pressed part 106 is a part pressurized by the reaction force receiving member 98 mentioned later. The pressurized part 106 includes an inclined surface 107 which is inclined with respect to the sliding direction of the sliding member 21c and an orthogonal surface 108 which is orthogonal to the sliding direction of the sliding member and is directly connected to the inclined surface 107.

In addition, the main hinge member 70c is fixed only to the door and is inserted into the hinge shaft 22.

In addition, the safe 100c of the present embodiment further includes a power transmission unit and a reaction force receiving member 98.

The power transmission unit transmits the rotational force of the door 30 to the reaction force receiving member 98 to rotate the reaction force receiving member. The power transmission unit includes a drive rotary member 95, a driven rotary member 96, and a belt 97.

The drive rotating member 95 is inserted into the hinge shaft 22 and rotatable about the hinge shaft 22. The drive rotation member 95 is formed to be stepped to reduce the diameter of the first drive rotation portion 951 and the first drive rotation portion 951, and the second drive rotation portion 952 disposed coaxially with the first drive rotation portion 952. ). On the outer circumferential surface of the first drive rotation part 951, a plurality of protrusions 9511 are formed to protrude while forming a radial shape. The second drive rotation unit 952 is fixed to the door 30, so that the drive rotation member 95 moves linearly with the door and rotates to the same degree in the same direction with the door. A portion of the drive rotation member 95 is disposed in the installation groove 213 of the sliding member.

The driven rotary member 96 is disposed in the installation groove 213 of the sliding member to be spaced apart along the sliding direction of the drive rotary member 95 and the sliding member 21c. The driven rotating member 96 is a pivot part 961 which is rotatably inserted into the upper and lower surfaces of the installation groove 213 of the sliding member, respectively, and the driven rotating part 962 formed on the outer circumferential surface while the plurality of protrusions 9621 are radial. ). Therefore, the driven rotating member 962 is rotatable about the pivot portion 961, and can slide together with the sliding member 21c. The central axis of rotation of the driven rotary member 96 is parallel to the central axis of rotation of the drive rotary member 95.

The belt 97 connects the drive rotary member 95 and the driven rotary member 96 to transfer the rotational power of the drive rotary member 95 to the driven rotary member 96. The belt 97 rotates around the drive rotary member 95 and the driven rotary member 96 in an endless track. The belt 97 is rotated by the frictional force between the drive rotary member 95 and the driven rotary member 96, but in this embodiment, the belt 97 is driven on the inner surface of the belt 97 in order to ensure the power transmission more reliably. Protruding portions 9511 and 9621 of the rotating member and the driven rotating member are respectively inserted to form insertion grooves 971. As described above, in the present embodiment, the power transmission unit is configured as a belt structure, but it is obvious that the power transmission unit may be configured as a power transmission structure by a chain and a sprocket.

The repelling force receiving member 98 is fixed to the driven rotating member 96 to rotate and linearly move with the driven rotating member 96. The reaction force receiving member 98 is formed in a bar shape and protrudes with respect to the outer circumferential surface of the driven rotary part 962 of the driven rotary member 96. When the door is rotated from the repulsive action position to the open position, the repelling force receiving member 98 presses the pressurized portion 106, but first presses the inclined surface 107 of the pressurized portion and then secondly the pressurized portion The orthogonal surface 108 is pressed. When the pressurized part 106 is pressurized in this way, the repelling force receiving member 98 is applied with the repelling force from the pressurizing part 106, so that the sliding member 21c coupled to slide together with the repelling force receiving member 98 is It automatically slides in the direction of protruding from the enclosure. In order to exhibit the repulsive force more effectively, an elastic member (not shown) such as rubber or urethane may be attached to the repelling force receiving member and the pressurized portion.

In the safe 100c configured as described above, when the door 30 is disposed in the closed position, the power transmission unit is arranged as shown in Fig. 12A, and in this state, the repulsive force is pulled out by pulling the door. When placed in the acting position, the power transmission unit is arranged as shown in Fig. 12B. Thereafter, when the door is rotated to open the interior of the enclosure, the drive rotation member 95 fixed to the door also rotates together with the door, and in this process, the rotational force of the drive rotation member 95 causes the belt 97 to rotate. It is transmitted to the driven rotary member 96 through the driven rotary member 96 is also rotated. As the driven rotating member 96 rotates as described above, the repelling force receiving member 98 fixed to the driven rotating member also rotates in the same direction as the driven rotating member, as shown in FIG. 12C. As described above, the reaction force receiving member 98 first presses the inclined surface 107 of the pressurized portion. If the door continues to rotate thereafter, the reaction force receiving member 98 presses the orthogonal surface 108 of the pressurized portion. When the repelling force receiving member 98 presses the pressurized portion 106 in this way, a repelling force for linearly moving the repelling force receiving member 98 in the direction of protruding from the housing 10 is applied, so that the door automatically slides. . As a result, even if the door 30 is rotated after only linearly moving to the reaction force acting position, the door is automatically linearly moved during the rotation of the door, so that when the inside of the enclosure is opened, the door is placed in the open position.

For reference, in FIG. 12, the sliding member and the like are omitted for the sake of simplicity of the drawings, and only the components sufficient to explain the operation mechanism of the present invention are shown.

Meanwhile, in the fourth embodiment, the sliding member is formed in a "l" shape, but the sliding member may be formed in a "b" shape as shown in FIG.

Referring to FIG. 13, in the present embodiment, the sliding member is viewed as a "b" shape as a whole when viewed from above as in the first embodiment. That is, the sliding member 21 includes a portion inserted into the sliding hole and a portion protruding without being inserted into the sliding hole 102c, and the inserted portion and the protruding portion form an angle of 90 degrees to each other. And since the hinge shaft 22 is fixed to the part which protrudes without being inserted, the hinge shaft 22 is spaced apart from the center axis line of the sliding hole 102c to the outside of the housing 30.

The power transmission unit further includes a pair of idlers 99. Each idler 99 is rotatably coupled to the sliding member and contacts the outer surface of the belt 97d. The belt 97d is divided into a first portion 971 and a second portion 972 by a pair of idlers 99 to form an overall “b” shape as shown in FIG. 13. The first portion 971 is a portion parallel to the central axis of the sliding hole 102c, and the second portion 972 is a portion orthogonal to the first portion 971.

For reference, FIG. 13 shows only the components necessary for the simplification of the drawings and the description of the operating mechanism of the present invention. In the present embodiment, unlike the fourth embodiment, the insertion groove is not formed in the belt, and the protrusion is not formed in the driving rotating member and the driven rotating member.

On the other hand, when the door is disposed in the open position, the first link and the second link of the first embodiment can be fully extended to form a link angle of 180 degrees as shown in FIG. At this time, the length of the sliding member and the sliding hole is formed longer than in the first embodiment. And the door is further rotated compared to the first embodiment. In addition, the stopper means for preventing further rotation in the state where the door is disposed in the open position may be configured to include the first stopper portion and the second stopper portion.

As shown in Fig. 14, a first stopper portion 5131 is formed in the first link 51d. The first stopper portion 5131 is formed of a protrusion formed to protrude from the connection portion 513 of the first link. The second stopper portion 35 is constituted by a groove concave in the inner surface of the door 30d. When the door is opened as shown in FIG. 14, the first stopper portion 5141 is inserted into the second stopper portion 35, and is formed on the inner surface of the second stopper portion 35. And the pressing portion 62 of the hinge member is still in contact with the pressing portion 514 of the first link. In this state, when the door 30d tries to rotate in the direction of further rotation beyond the open position, the inner surface of the second stopper portion 35 presses the first stopper portion 5191 so that the link angle θ is increased. Although a decreasing moment is generated, the pressurized portion 514 of the first link is in contact with the pressing portion 62 of the hinge member to prevent rotation of the first link, so that the door 30d can no longer rotate and open. It stops in position and the link angle remains the same. Therefore, the maximum rotational position of the door is caused by the interaction between the first stopper portion 5131 and the second stopper portion 35 and the pressurized portion 514 of the first link and the pressing portion 62 of the hinge member. Limited.

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.
