No. 5806).

[0005]

However, the above-mentioned dial lock has the following disadvantages. That is, when the rotary dial is rotated left and right, a slight change in resistance and a change in sound are sensed. there were.

The security lock disclosed in Japanese Patent Application No. 11-145806 has the following problems. That is, there is a problem that the first sensor provided in the key insertion slot is destroyed by improper means. Further, there is a problem that the lock mechanism is released after the set time elapses even while the lock mechanism is operating.

Further, when the control mechanism and the lock mechanism are driven by a battery, there is a problem that the remaining capacity of the battery is reduced, so that even if the lock mechanism does not operate, it is not noticed. Furthermore, when the remaining capacity of the battery is low, there is a problem that the locked state is not released due to the shortage of the remaining capacity of the battery.

Further, when the control mechanism and the lock mechanism are driven by an AC power supply, there is a problem that the control mechanism and the lock mechanism do not operate at the time of a power failure or the like. Further, when the lock mechanism is operating, there is a problem that an emergency situation occurs and the lock cannot be unlocked even if the lock is to be unlocked from the room.

Therefore, the present invention has been developed in view of the above-mentioned drawbacks of the prior art, and is unlocked even when a change in resistance or a change in sound when the rotary dial is rotated left and right is sensed. The purpose is to provide a dial lock that is impossible.

Embodiments of the present invention will be described below in detail with reference to the drawings.

(Embodiment 1) FIGS. 1 and 2 show this embodiment. FIG. 1 is a side view and FIG. 2 is a rear view. 1 is a dial lock, and the dial lock 1 is attached to a door 2 of a safe or the like. Dial lock 1 is dial 3 and dial 3
Three rotating plates 4, 5, which are rotatably fitted to the rod 3a of
6 and a locking rod 7 that engages with the notches 4a, 5a, 6a of the rotating plates 4, 5, 6.

Each of the three rotating plates 4, 5, and 6 has a notch 4a, 5a, 6a with which the tip of the locking rod 7 engages, and rotates the dial 3 left and right a plurality of times under constant conditions. In this case, the notches 4a, 5a, and 6a are arranged on the same line. Three rotating plates 4,
The switches 5 and 6 turn on the switch of the dial lock 1 according to the movement of the three rotating plates 4, 5 and 6, and are provided with a first sensor 8 for detecting the movement.

The locking rod 7 has three rotating plates 4, 5, 6
The notches 4a, 5a, and 6a are movably supported so that their tips can be engaged when they are aligned on the same line, and the other end is deadlocked and has a main body such as a safe (not shown). ) To fix the door 2. Further, a lock rod insertion hole 7a is formed substantially at the center of the lock rod 7.

In the vicinity of the lower part of the lock rod insertion hole 7a, a lock rod driving device 10 for supporting the lock rod 9 so as to be vertically movable is installed. When the lock rod 9 is lifted by the lock rod driving device 10, the lock rod 9 is raised. The upper end portion 9 is configured to fit into the lock rod insertion hole 7a.

A second sensor 11 for detecting the movement of the lock rod 7 is provided at a position substantially out of the center of the lock rod 7 so as not to contact the lock rod insertion hole 7a. The first sensor 8 and the second sensor 11 for detecting the movements of the three rotating plates 4, 5, 6 are connected to a control mechanism 12, respectively. The control mechanism 12, the first and second sensors 8, 11 and the driving device 10 are driven by a battery (not shown).

When the dial 3 is rotated left and right, the dial lock 1 having the above structure
The three rotating plates 4, 5, and 6, which are rotatably fitted to the gears, are interlocked. The switch of the control mechanism 12 is turned on by the movement of the three rotating plates 4, 5, and 6, and the first
A detection signal is transmitted from the sensor 8 to the control mechanism 12.

The control mechanism 12 which has received the detection signal
After a certain time has elapsed (after two minutes in the present embodiment), the second sensor 11 checks whether the locking rod 7 has moved. When the locking rod 7 has been moved, it is determined that the unlocking operation is performed by normal means, and the switch of the control mechanism 12 is turned off. That is, the power supply to the control mechanism 12, the first and second sensors 8, 11 and the driving device 10 is stopped.

When the locking rod 7 has not moved, the control mechanism 12 determines that the dial lock 1 is about to be unlocked by illegal means. Thereafter, the control mechanism 12 sends a signal to the drive device 10 to raise the lock rod 9 and fit the tip of the lock rod 9 into the lock rod insertion hole 7 a of the lock rod 7. By this fitting, the dial lock 1
The lock itself becomes in a locked state, and unlocking by an unauthorized means becomes impossible.

After the lock state of the dial lock 1 itself has been locked for a certain period of time (after three hours in the present embodiment), a signal is transmitted from the control mechanism 12 to the drive device 10 to lower the lock rod 9. This lowering causes the dial lock 1
The locked state of itself is released, and then the switch of the control mechanism 12 is turned off. That is, the power supply to the control mechanism 12, the first and second sensors 8, 11 and the driving device 10 is stopped.

In the present embodiment, the fixed elapsed time from the reception of the detection signal is 2 minutes, and the fixed elapsed time of the lock state of the dial lock 1 itself is 3 hours, but the present invention is not limited to this. The elapsed time can be freely set without limitation.

Although a battery is used in the present embodiment, the present invention is not limited to this. Instead of the battery, a backup device may be provided inside and an AC power supply may be used. Further, a battery and an AC power supply can be used together.

Further, in this embodiment, the lock rod insertion hole 7a for fitting the tip of the lock rod 9 is formed. However, the present invention is not limited to this, and the lock rod insertion hole 7a is used instead of the lock rod insertion hole 7a. A notch or the like with which the tip of the lock rod 9 engages may be formed.

When a battery is used, it is recommended to provide a remaining capacity display device. Further, in case the remaining capacity of the battery decreases, the lock rod driving device 10
It is recommended to add a driving force increasing function that operates when the lock rod 9 descends.

According to the present embodiment, a battery is used as a power source that does not require complicated wiring. However, the power source of the battery is used only when the lock of the dial lock 1 is released.

The control mechanism 12 which has received the detection signal
After a certain time has elapsed (after two minutes in this embodiment), the control mechanism 12 sends a signal to the lock rod driving device 16 to raise the lock rod 9, and the tip of the lock rod 9 is The lock rod insertion hole 7a is fitted.

At this time, if the unlocking operation is normal, the locking rod 7 has already moved, and the tip of the lock rod 9 cannot be fitted into the lock rod insertion hole 7a. Accordingly, the lock rod driving device 16 raises the lock rod 9 with a constant driving force, and then lowers the lock rod 9. Upon detecting this state, the control mechanism 12 determines that the unlocking operation is performed by normal means, and turns off the switch of the dial lock 15.

If the lock rod 7 has not moved, that is, if the tip of the lock rod 9 can be fitted into the lock rod insertion hole 7a, the control mechanism 12 attempts to unlock the dial lock 1 by an unauthorized means. Judge that there is.
