The present invention relates to a main door lock of a large safe door that is installed in a cash storage room of a financial institution or a confidential document storage room of a general company.

In general, large vault doors, such as financial institutions, are made of thick steel plates and fireproof materials to provide sufficient anti-theft and fire resistance.

Most of the vault doors are rotational type in which the main door is freely rotated on the door frame, but recently, a sliding type that opens and closes the access passage while the main door slides back and forth has appeared.

On the other hand, the vault door has almost a perfect lock on the main door, regardless of how the main door is opened or closed, and the lock is mostly rotated at a certain angle in several forward and reverse directions so that it can be released from the locked state. A plurality of dial locks are key components.

In addition, the locking device is provided with a handle-type or lever-type operation handle that is constrained by a lock, a rotating body connected thereto, and an operation that directly restrains the main door.

5 shows one conventional locking device.

This conventional apparatus is provided in the main door 300 which is slidably transported, and is provided with the above-mentioned dial-type lock 310 in the center part, and the lock 310 has a dial plate 320 on one side thereof. ) Is bound.

In addition, the dial plate 320 is configured to constrain the lower operation section 360 coupled to the upper operation section 350 on the rotating plate 340 interlocking with the opening / closing handle (not shown) installed on the front surface of the main door 300. .

To unlock the main door 300 through this conventional locking device, first release the dial lock 310 to prevent the dial plate 320 from constraining the lower operation section 360, and then move the operation knob in one direction. By rotating the rotating plate 340 to move the tip of the upper and lower operation between the main door 300, the upper and lower operation 350, 360 inside the main door 300.

5 shows a conventional locking device which releases the main door in a restrained state in this manner.

As such, the conventional locking device is often provided inside the main door 300.

However, in the case of providing a locking device in the main door 300, of course, it is difficult to produce the main door 300.

In addition, since the space for installing the locking device inside the main door (300) must be secured, the main door (300) becomes considerably thicker and the weight becomes heavy, and it is not good to see, and he has a difficulty in performing the smooth opening and closing operation. Will be raised.

In addition, since the main door is not fixed but is rotated or slid to open and close the access passage, according to the conventional apparatus, damage or positional change of parts may occur due to the impact received during the operation of the main door 300.

In addition, the conventional apparatus lacks a means for releasing the locked state of the main door 300 and maintaining the unlocked state.

Therefore, when the operation handle is rotated by an external impact or inadvertent use, the tip ends of the lifting legs 350 and 360 protrude from both ends of the main door 300 to be rubbed into the door frame to thereby open and close the main door 300. There is a problem that is hampered.

The problem caused by the operation handle being rotated after the restraint state of the main door is released becomes more serious when the main door is configured by rotation.

That is, the main door 300 may not be closed in the state in which the operation doors 350 and 360 protrude, but it is because the operation doors 350 and 360 stop the rotation of the main door.

In addition, according to the conventional apparatus, since a lot of rotation torque is generated in the process of operating the operating sections 350 and 360 by the rotating plate 340, there is a problem in that a lot of force must be applied to rotate the operation handle.

The present invention has been devised in view of the above conventional situation.

An object of the present invention is to provide a main door lock of a large safe door so that it can be operated more smoothly without inhibiting the opening and closing operation of the main door.

Another object of the present invention is to provide a main door lock of a large safe door that allows the main door to be more compactly constructed.

Still another object of the present invention is to provide a main door lock device for a large safe door to release the restraint state of the main door and thereby restrain the operation handle to maintain a stable release state.

The main feature of the present invention for achieving the above object is to provide a lock to the door frame first.

In addition, the present invention is characterized in that to configure the locking device to operate the braking between the operation, the safety between at the same time through the drive gear interlocked with the operation handle.

Hereinafter, the present invention will be described in more detail with reference to specific embodiments shown in the accompanying drawings.

When the drive gear 120 rotates in the above, the braking section 130 is transported in the horizontal direction, and the operation section 140 and the safety section 150 are transported in the vertical direction, but the operation section is opened to both sides of the drive gear 120 ( 140 and the safety section 150 is spaced in front and rear with the brake section 130 so that they do not interfere with each other's operation.

Meanwhile, the upper end of the operation section 40 is provided with a latch 142 of one side bent downward.

The clasp 142 is brought in and out from the upper portion of the door frame 10 to the access passage 70 as the operation period 140 moves up and down.

The upper portion of the main door 20 is provided with a space portion 22 to allow the catch 142 to enter and exit, and the catch 142 descending together with the operation period 140 is one side of the space portion 22. It is caught in the stage is to stop the transfer of the main door (20).

As shown in FIG. 4, the horizontal section 160 is installed on the protruding pieces 111 of the pair of dial locks 11 provided over the front door frame 11 and the machine room front plate 91, and the lower center of the horizontal section 160 is provided. There is a vertical section 170 is installed.

The vertical slot 170 is also provided with a plurality of slide slots 173 coupled to the plurality of support shafts 93 protruding from the machine room front plate 91.

On the other side of the rotational section 180, one side of which is installed over the vertical section 170, a locking section 190 of one side is bent downward.

Similar to the vertical section 170, the locking section 190 is also provided with a slide long hole 193 is coupled to the support shaft 93 of the machine room front plate 91, the base 200 is installed below.

The stiffening interval 190 has a lower end thereof to be able to ascend and penetrate through the interior of the base 200, and also has a lower end thereof corresponding to one end of the braking interval 130 described above.

Rotating shaft 180 is coupled to the pivot center 94 protruding from the machine room front plate 91, the center portion thereof is rotatable, and the connecting shaft at a position corresponding thereto through the hook hole 181 formed on both sides thereof. 171 and 191 are connected to the vertical section 170 and the locking section 190 formed.

Therefore, as will be described later, when one side of the pivot 180 descends through the vertical section 170, the other side of the pivot 180 rises in the opposite direction, thereby locking the interlock 190 that restrains the brake section 130. The upper portion is transferred to the upper portion, and then the driving gear 120 and the braking rod 130, the operating rod 140, the safety rod 150, and the like may be operated through the manipulation handle 100.

On the other hand, the machine room front plate 91 of the lower side of the safety interval 150 is provided with an elastic rotation interval (210).

The elastic pivot 210 is coupled to the pivot center 94 protruding from the machine room front plate 91 so that its center portion is rotatable, and the hook piece 95 provided on the machine room side plate 92 and an upper side thereof. Receiving elasticity of the tension spring 220 is installed over.

The operating rod 230 and the catching rod 240 are installed at one upper side and the other lower side of the elastic pivot 210.

The operating rod 230 and the engaging rod 240 is horizontal reciprocating transfer through the support 96 is installed on the machine room side plate 92 and the machine room front plate 91, the operating rod 230 is machine room side plate 92 It can be protruded into the access passage 70, the locking rod 240 can be inserted into the locking groove 152 formed on one side lower portion of the safety section 150.

By the way, since the elastic spring 210, the elastic spring of the tension spring 220 at the upper end of one side acts to actuate the operating rod 230 is always subjected to a force to protrude into the access passage 70 and the locking rod 240 is a safety rod You will be forced to advance to 150.

Reference numeral 112 in the drawings denotes a dial of a lock, and 250 denotes a building wall.

Figure 4a shows the main door 20 is restrained by the locking device of the present invention configured as described above.

The main door 20 cannot be transported because the latch 142 of the operation 140 is positioned at one inner end of the space 22 provided at the upper portion thereof.

In this case, the locking rod 190 operated by the lock 110 is in a lowered state, and thus the braking rod 130 cannot be transferred.

Since the braking section 130 engaged with the driving gear 120 restrains the operation knob 100 on the front of the door frame 10, in this state, the braking section 130 is moved up and down by the rotation of the driving gear 120. It is not possible to operate the safety section 150.

On the other hand, since the main door 20 is closed, one side of the main rod 20 presses the operating rod 230 protruding into the access passage 70, so that the locking rod 240 of the lower portion of the elastic pivot 210 has a safety interval 150. It will be pulled to the other side.

When the main door 20 is locked as described above, the dominant pair of locks 110 must be manipulated.

When the dials of the locks 110 are rotated in a coded manner, the protrusions 111 of the locks 110 are lowered, and thus the horizontal legs 160 and the vertical members 170 coupled to the protrusions 111 are thereby lowered. This will descend.

The vertical rod 170 rotates while rotating the pivot 180, and the pivot 180 raises the latch 190.

When the locking section 190 is raised, the braking section 130 moves out of the restrained state as shown in FIG. 4B, and thus the operation of the driving gear 120 and the operation handle 100 is possible.

After releasing the lock 100, the operator can release the locked state of the main door 20 by rotating the operation knob 100 to one side.

Rotating the operation knob 100 causes the drive gear 120 to rotate, and the drive gear 120 transfers the braking rod 130 in the horizontal direction while simultaneously moving the operation rod 140 and the safety rod 150 in the vertical direction. Will be transferred.

That is, the driving section 140 of one side of the driving gear 120 is raised so that the latch 142 is released from the space 22 of the main door 20 to release the restrained state of the main door 20. .

Unlike the operation interval 140, the safety interval 150 is moved down to the position that can be inserted into the locking rod 240 of the elastic rotation interval 210 in the locking groove 152.

After the operation 140 and the latch 142 is raised, the main door 20 can be opened through the operation button 81 of the control panel 80.

4B shows a state in which the main door 20 is slightly open.

When the main door 20 is opened, the elastic pivot 210, which was restrained by the operating rod 230 pressed by one side thereof, rotates through the tension spring 220, and thus the operating rod 230 enters and exits. Protruding into the passage 70 and the locking rod 240 is inserted into the locking groove 152 of the safety section 150.

When the locking rod 240 restrains the safety section 150, the driving gear 120 engaged with the safety section 150 may not operate, and the braking section 130 engaged with the driving gear 120 may not operate. 140 is not movable, it is not possible to rotate the drive gear 120 through the operation handle (100).

Therefore, according to the present invention, the driving gear 120 is restrained in the open state of the main door 20 to prevent the operation 140 and the lowering of the latch 142, so that the main door 20 can be operated without interference of the locking device. It becomes possible.

The restraint of the drive gear 120 and other components by the safety clearance 150 is released only when the main door 20 completely closes the access passage 70.

That is, when the main door 20 is completely closed, one side of the main door 20 is pressed by the operating rod 230 of the elastic pivot 210 protruding into the access passage 70, and thus the locking rod 240 is the safety rod 150. It will be out of the locking groove 152 of the).

When the safety wheel 150 becomes free again, it becomes possible to lock the main door 20 by rotating the drive gear 120.

That is, when the operation handle 100 is rotated in one direction after the main door 20 is completely closed, the operation lever 140 may be lowered by the driving gear 120.

When the operation 140 is lowered at the same time, the safety interval 150 is raised at the same time, as well as the braking interval 130 is transferred to one side, so that the main door 20 is completely restrained through the operation knob 100. It is possible to restrain the braking rod 130 through the dial 112 of the lock 110.

That is, when the main door 20 is completely sealed, the braking rod 130 is in a state of being transferred to one side. At this time, when the dial 112 of the lock 110 is rotated, the protrusion 111 of the lock 110 is raised. Therefore, the horizontal section 160 and the vertical section 170 are raised accordingly, and the vertical section 170 rotates the rotation section 180 to lower the latch section 190 by rotating the braking section 130. Will be constrained.

When the brake 130 is restrained again as shown in FIG. 4A, the driving gear 120 may not operate. Therefore, the operating section 140 and the safety section 150 coupled to the driving gear 120 may not move, and the operation handle may be moved. 100 also cannot be rotated.

Therefore, without dismantling the lock 110 again, it is not possible to rotate the operation knob 100 to release the main door 20 from the locked state.

As described above, the present invention constrains the braking interval 130 and the driving gear 120 to the locking interval 190 which is operated by the lock 110 in the locked state of the main door 20. Not only to maintain the locked state of the solid main door (20) by preventing the rotation, but also the safety wheel 150 and the drive gear through the locking rod 240 of the elastic rotating piece (210) even when the main door (20) is open By restraining the operation 120 to prevent the falling of the operation 140 and to suppress the rotation of the operation knob 100 can be maintained in a solid open state according to the present invention main door 20 is the access passage 70 Benefits are provided that can reliably eliminate interference with locking devices that can occur when opening and closing.

And since the present invention does not provide a means for the locking device other than providing the space portion 22 to the main door 20, the latch 142 of the operation 140 to enter and exit, so according to the present invention The effect which can shape | mold (20) more compactly can be acquired.

In addition, the present invention can reduce the rotational torque by transferring the operation between the operation 140 and the safety interval 150 through the drive gear 120, according to the present invention, the operation handle (easily with a much smaller action force than the conventional) 100) can be operated.
