Description

Security 3D Recognition System

[0001] The present invention relates to a security 3D recognition system that prevents unauthorized unlocking by picking a key or the like by linking with a locking device that opens and closes with a key.

[0002] Keyhole-type and electronic locks have traditionally been used as locking devices for entrance doors of homes, offices, etc. For example, locking devices such as those shown in Patent Documents 1 and 2, as well as locking devices using more advanced mechanical and electronic technologies, have been developed.

[0003] Japanese Patent Laid-Open No. 08-004374 Japanese Patent Laid-Open No. 2006-207361

[0004] As mentioned above, although keyhole-type and electronic locking devices using advanced mechanical and electronic technologies have been developed for use on entrance doors of homes, offices, etc., thefts and accidents caused by unauthorized unlocking by lock picking and the like continue to occur due to factors such as limited time available to security company personnel. In order to solve the above problem, the present invention aims to provide a security 3D recognition system for preventing unauthorized unlocking by lock picking, unauthorized radio waves, unauthorized magnetic fields, etc.

[0005] The security 3D recognition system of the present invention is characterized by comprising a locking device that is opened and closed with a key, and a recognition box that is linked to the locking device and opens and closes the keyhole of the locking device with a connected plate, and that recognizes original solids that have a unique shape that can be distinguished from others.

[0006] The recognition box is characterized by having a recognition means for recognizing, from at least one direction on the entrance side, the unique shape of the original solid that can be distinguished from others by inserting the original solid. After the original solid is inserted from the entrance, the recognition is performed after the lid is closed, which prevents picking.

[0007] The recognition box is characterized in that a plurality of cylinders equipped with cylindrical pins for recognizing the surface of the inserted original solid are provided at a predetermined interval at least at the entrance side, and the pins are each formed with a concave, convex, or divided shape for recognizing shear lines, and when the shear line of the pin abutting the surface of the original solid is established, the connected plate opens and closes the keyhole of the locking device.

[0008] Furthermore, the recognition box is characterized in that it is linked so that the keyhole blocked by the plate of the locking device opens only when it recognizes that the inserted original solid is the original solid corresponding to the recognition box.

[0009] The recognition box is characterized in that when the original solid corresponding to the recognition box is inserted and unlocked, the original solid cannot be removed, and when the locking device is locked and the key is removed, the inserted original solid can be removed.

[0010] Use of the security 3D recognition system of the present invention prevents lock picking and, since it does not use electronic devices or magnetism, it eliminates unauthorized intrusions by these means, and therefore eliminates theft and accidents due to bumping into others.

The figure also shows a flowchart for locking and unlocking, with (A) showing the flow from a locked state and (B) showing the flow from an unlocked state.

[0012] An example of an embodiment of the present invention will be described with reference to Figures 1 to 11. An original solid 2 as shown in Figure 2 is inserted into the recognition box shown in Figure 1.

[0013] After insertion, the original solid 2 is fixed in the state shown in Fig. 3. The state in Fig. 3A is a recognition-compatible state, but the state in Fig. 3B is a recognition-incompatible state because it has not been fixed.

[0014] An original solid 2 is inserted into the recognition box surrounded by a spring-loaded pin case 3 and a pin case 4. In this example, the original solid is recognized by pins 6 from six directions.

[0015] 5 shows the internal structure of the spring-loaded pin case 3 and the pin case 4. When an original lid corresponding to the recognition box is inserted, the spring-loaded pin case 3 and the pin case 4 are separated by a shear line 7.

[0016] In this embodiment, the spring-loaded pin case 3 and the pin case 4 are designed as shown in Fig. 6. The spring-loaded pin 5 is attached inside the spring-loaded pin case 3, and the pin case 4 is provided with a pin 6 inside.

[0017] FIG. 7 shows the design drawings of shear line split shutter A9 and shear line split shutter B10 that slide into the shear line.

[0018] By moving the spring-equipped pin case 3 and pin case 4 designed in FIG. 6 inside the recognition box shown in FIG. 8A, it becomes possible to recognize the original solid 2 from six directions.

[0019] In Figure 6, (A) is a plan view, (B) is a front view, and (C) is a side view. First, the spring-loaded pin case 3 and pin case 4 shown in Figure 6 with the original solid 2 inserted are faced toward the back with the side shown in Figure 6(B) facing the rear, and the original solid insertion lever 11 is used to push them toward the rear, so that the shear line split shutter A9, which is installed and fixed so that its opening faces the entrance side, slides into the shear lines 7 on the upper, lower, right, and left sides of the spring-loaded pin case 3 and pin case 4. Next, the locking device cylinder opening closing plate 12 is slid to the left using the lever 22 on the locking device cylinder opening closing plate 12, and the shear line split shutter B10, which is connected to the locking device cylinder opening closing plate 12 by the connecting shaft 13, slides into the front and rear shear lines 7 on the side shown in Figure 6(C), which shows the right side of the spring-loaded pin case 3 and pin case 4.

[0020] When the shear line split shutter B10 recognizes the original solid 2, the shape of the original solid 2 is completely recognized from six directions, and the locking device cylinder mouth closing plate 12, which is linked to the shear line split shutter B10 by a connecting shaft 13, is slid using the lever 22 of the locking device cylinder mouth closing plate 12 to open the cylinder mouth of the locking device.

[0021] FIG. 9 shows an example of a door type, showing the original solid insertion openings of the spring-loaded pin case 3 and the pin case 4 shown in FIG. 6 and the original solid insertion opening 1b of the recognition box.

[0022] 8B, inside the recognition box, the original solid insertion lever 11 is slid, and the toothed belt 15 and gear 14 move the rack 16, which then moves the spring-loaded pin case 3 and pin case 4 mounted on it to the back. After that, because the original solid insertion lever 11 has moved to the left, the locking device cylinder opening closing plate 12 is slid to the left using the lever 22 of the locking device cylinder opening closing plate 12, opening the cylinder opening of the locking device.

[0023] Using the flowchart shown in Figure 11, we will explain the interaction between the security 3D recognition system and a locking device that uses a key to open and close it. The original solid 2 can only be recognized by the corresponding recognition box 1a, 1b. When the original solid 2 is inserted (S3), the locking device cylinder port closing plate 12 is opened (S5), and the key is opened (S6), the original solid insertion port 1b is locked (S7).

[0024] That is, as shown in FIG. 8A, by inserting a key into the cylinder 8 and turning it in the direction to open the lock, the cylinder cam 17 rotates, and the locking device cylinder opening closing plate 12 is locked by the hook-type latch 23 linked with the shaft or plate 21 shown in FIG. 8C, and the original solid insertion lever 11 is also stopped.

[0025] The shape of the original solid 2 is recognized by closing the original solid insertion port 1b of the recognition box, thereby preventing picking.

[0026] Next, when the lock is locked (S13), the original solid insertion port 1b is unlocked (S14), the key is removed (S15), the locking device cylinder port is closed with the locking device cylinder port closing plate 12 (S17), and the original solid 2 is removed (S18). Since the keyhole 20 is closed and the original solid 2 has been removed, picking is prevented.

[0027] That is, as shown in FIG. 8C, by inserting a key into the cylinder 8 and turning it in the direction of locking, the cylinder cam 17 rotates, and the hook-type latch 23 linked to the shaft or plate 21 shown in FIG. 8C is released, the locking device cylinder opening closing plate 12 is also released from the lock, and the original solid insertion lever 11 also moves.

[0028] Therefore, by locking the insertion port of the original solid 2 in conjunction with the key of the locking device, the theft of the original solid 2 can be prevented and at the same time the key can only be used when the original solid 2 is inserted.

[0029] When locking the door from inside the room, an inner lock on the original solid insertion port 1b from the inside is required to prevent card theft. This is because there is a possibility of theft from outside, where the cylinder is picked to lock the door, remove the original solid 2, and make a copy. Also, when going out with the door locked, a simple lock can be used on the original solid insertion port 1b to prevent tampering.

[0030] 10 shows the interlocking with the deadbolt. When the lock is locked from the outside, both deadbolt A18 and deadbolt B19 close due to interlocking with the locking device cylinder cam 17, and the original solid insertion port 1b of the recognition box linked to deadbolt A18 is unlocked. When the lock is locked from the inside, only deadbolt B19 closes, and the original solid insertion port 1b of the recognition box is not unlocked.

[0031] That is, the locking device cylinder cam 17 is connected to the deadbolt A18 and deadbolt B19 by a shaft or plate 21. The deadbolt B19 is connected to the side closer to the cylinder of the locking device cylinder cam 17, and the deadbolt A18 is connected to the side farther away. Because the cylinder moves in a circular motion, a lag occurs in the left and right movement of the deadbolt A18 and deadbolt B19. This is utilized.
