Abstract

PURPOSE:To prevent a valuables keeping device from being unlocked excepting for a set time and to much more improve crime prevention function by providing a timer to generate an output signal showing an unlock time band. CONSTITUTION:An unlock right owner 2 of a trunk 1 for keeping and transporting valuables has a key 3 and an identification signal oscillator 4 to show that the person 2 owns the right of lock operation. In the trunk 1, a receiver 6 for an identification signal from a transmitter 4 and a timer 7 to generate the output signal showing the unlock time band. A system manager sets the timer 7 and the unlock right owner 2 approaches the trunk 1 and oscillates the identification signal from the oscillator 4. Then, when the receiver 6 of the trunk 1 receives the signal and the key 3 is inserted to a key receiver 5, an unlock request signal is inputted to a control circuit 9. The circuit 9 checks the output signal of the timer 7. In the case of the unlock time band, an unlock command is outputted to a driving circuit 10 and an electric lock 11 is unlocked. In the other case, the circuit does not execute the unlock operation. Since the device can not be unlocked excepting for the set time, the safety of valuables can be guaranteed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a valuables storage device used for storing and transporting valuables such as cash, jewelry, and precious metals.

[Prior Art] Conventionally, when storing valuables such as cash, jewelry, and precious metals, it is common to lock the storage device. the current,
There are various types of keys, from simple ones that open by inserting the key into the keyhole and turning them, to ones that use a magnetic card as a keyhole, and electric locks that open by entering a code number. has been done. In addition, in order to ensure that only specific individuals can unlock the lock, when a person carrying a small identification number transmitter approaches, a receiver connected to the lock reads the identification number, and the identification number is registered in advance. An electronic unlocking system has also been proposed that automatically unlocks the door if the lock matches the lock.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, if an unlocking means such as a key, a magnetic card, a code number, or an identification number transmitter is used, no matter who the user is, Since the storage surface can be unlocked, there is a problem in that it is impossible to prevent the lock from being unlocked by an outsider who somehow obtains the unlocking means. Also,
There is also the problem that unauthorized unlocking by a person qualified to use the unlocking means cannot be prevented.

The present invention has been made in view of these points, and its object is to provide a liquid storage device that cannot be unlocked unless conditions other than the unlocking means are met.

[Means for Solving the Problems] In order to solve the above-mentioned problems, in the valuables storage device according to the present invention, as shown in FIGS. An identification signal receiver 6 is provided to receive the identification (U) from the identification signal transmitter 4 which transmits an identification signal indicating the unlocking time, and a timer 7 which generates an output signal indicating that it is the unlocking time period is provided. The unlocking operation is enabled only during a preset unlocking time period.

[Function] In the present invention, as described above, since the timer 7 is provided which generates an output signal indicating that it is the unlocking time period, the system administrator can check the time period when the legitimate unlocking operation is to be performed. If you also set the timer 7 in advance, someone who somehow obtains the unlocking method will try to unlock the lock.
Even if the person in possession of the unlocking means attempts to unlock the lock illegally,
It will not be unlocked outside of the set time. Therefore, the crime prevention function is significantly enhanced.

[Embodiment] FIG. 2 is a block diagram showing a schematic configuration of an embodiment of the present invention, and FIG. 1 is a perspective view of the embodiment applied to a trunk for e-transporting heavy items. In the figure, ■ indicates n1 item storage/

5 is a key holder on the trunk side, and 6 is an identification signal transmitter 4.
is a receiver for the identification signal transmitted from the

Further, S represents the reachable area of the identification signal sent from the identification signal transmitter 4.

7 is a timer for generating an output signal indicating that it is the unlocking time period, and 8 is an input device for setting the unlocking time period in the timer 7. Reference numeral 9 denotes a control circuit including a microcomputer, etc., which checks the presence or absence of an unlocking request and the output signal of the timer 7. 10 is a drive circuit for an electric lock, and 11 is an electric lock.

The operation of this embodiment will be explained below. First, the system administrator uses the input device 8 to set the timer 7 built into the trunk 1, and makes the unlocking right holder 2 carry the key 3 and the identification signal transmitter 4.

The identification signal transmitter 4 transmits a specific identification signal within a certain area S. When the unlocking right holder 2 approaches the trunk 1 and the trunk 1 enters the area S, the identification signal receiver 6 of the trunk 1 receives the identification signal. Solution 52 When the right holder 2 wants to unlock the trunk 1, he inserts the key 3 into the key holder 5. At this time, an unlock request signal is input to the control circuit 9 from the key receiver 5 and the identification signal receiver 6. 2
When one unlock request signal is input, the control circuit 9 checks the output signal of the timer 7. The timer 7 determines the time period set by the system administrator during which unlocking operations are allowed, and
Different output signals are output to the control circuit 9 at other times. The control circuit 9 sends an unlock command to the drive circuit 10 to unlock the electric lock 11 only when the timer 7 outputs an output signal indicating that it is the unlock time period. When the timer 7 does not output an output signal indicating that it is the unlocking time period, the control circuit 9 does not perform the unlocking operation and determines that an unauthorized attempt has been made to unlock the lock. Memorize facts and times. Additionally, an alarm device may be added to issue a warning using sound, light, or radio waves if an attempt is made to unlock the door illegally. It would be advantageous if the locking operation is automatically performed when the door 1 is closed and the key 3 is removed from the key holder 5, since this prevents forgetting to lock the door. The locking operation may be always possible, or the locking operation may be configured such that the locking operation can be performed only during unlocking hours.

In the above embodiment, two conditions were exemplified as the unlock request signal: insertion of the key 3 and reception of the identification signal, but the number of other conditions may be as many as 6 conditions. If it exists, as shown in the block diagram of FIG.
A condition memory 12 for storing each condition 1 to n is added to the control circuit 9, and when the conditions 1 to n are satisfied and the identification signal is received, the output signal of the timer 7 is checked, If it is during the unlocking time period, the control may be performed to unlock the door. Note that the conditions 1 to n shown in FIG. 3 are not limited to the insertion of the key 3.

[Effects of the Invention] In the valuables storage device of the present invention, if the timer is set in advance according to the time period when the lock is legitimately unlocked,
Even if a person who obtains the unlocking means by some means tries to unlock it, or even if the legitimate owner of the unlocking means tries to unlock it illegally, it will not be possible to unlock it outside of the set time.
This has the effect of guaranteeing the safety of valuables stored inside.
