The inner cover body 12 is covered.

  Next, the configuration of the antitheft device of the present invention will be described with reference to FIGS. A tilt sensor 13 for detecting that the entire safe 1 is tilted back and forth or left and right by a predetermined angle from an upright posture; a lock sensor 14 for detecting that the lock (cylinder lock) 7 has been subjected to a picking attack; The controller 6c of the electronic lock 6, the locking sensor 15 for detecting the locking / unlocking state of the lock 7 itself, and the handle sensor 17 for detecting the locking / unlocking operation of the handle 8 and the opening / closing state of the door. Are connected to the input unit of the controller unit 10 via the switch input unit 16 or the like. The lock sensor 14 signals when the cylinder portion does not rotate quickly (within a predetermined time after the key or picking tool is inserted), such as when the lock (cylinder lock) 7 is subjected to a picking attack. Is output.

  Then, when the power line 20 for introducing power from the power supply outside the safe 1 to the controller unit 10a and the abnormal output of the anti-theft sensor are transmitted to the controller unit 10a, an abnormal signal is transmitted to the monitoring device 22 outside the safe 1 The signal line 21 to be connected to the first and second connection parts 24 and 34 in the relay box 23 provided on the outer surface of the safe 1, respectively, and when the safe 1 moves or falls, the power line 20 and The signal line 21 is configured to be disconnected, and the power line 20 and the signal line 21 are disconnected to transmit an abnormal signal to the monitoring device 22. As an embodiment, in order to supply normal power to the controller unit 10a, an A / C adapter 25 connected to an outlet (not shown) of a commercial power supply (AC power supply such as 100 volts) outside the safe is used. The power line 20 is connected to one end. In the A / C adapter 25 of the embodiment, AC 100 volts is converted to DC 6 volts.

  The other end of the power line 20 is connected to one first connection portion 24 in the relay box 23, and the first connection portion 24 and the power input portion 32 of the step-down circuit 30 in the controller unit 10 on the inner surface of the door are for the power line 20. Is connected to the internal wiring 31a, and the electric power stepped down to 3 volts DC by the step-down circuit 30 is input to the controller unit 10a.

  The first connection unit 24 is configured such that the other end of the power line 20 can be easily disconnected outside the safe 1 when the safe 1 falls or is largely moved from the installation position. The other end side of the power line 20 (the side that is easily detached) is connected to a plug 24a (single-head plug, pin plug, DIN plug, etc.), and the internal wiring 31a side (fixed side to the relay box 23) is connected to the plug 24a. It is connected to the female jack 24b to be inserted (see FIGS. 7, 8, and 9). The base plate 35 in the relay box 23 is fixed with screws 36 or the like along the outer surface of the back plate 2a of the main body 2 of the safe 1, and the jack 24b passes through the lower horizontal plate portion 35a of the base plate 35 and is screwed. (See FIGS. 7 and 8).

  On the other hand, one end of the signal line 21 (indicated by two lines in FIG. 9) is connected to a relay controller 26 disposed indoors, and is placed outdoors (a remote place such as a remote place) via a line network 27 such as a telephone line or a dedicated line. ) Is connected to the monitoring device 22. The monitoring device 22 may be a communication (reception) device of a contracted security company.

  When an abnormal situation is determined from the output signals of the sensors described above and an abnormal signal is output from the controller unit 10a, the relay 29 is driven via the relay drive circuit 28 connected to the output unit of the controller unit 10a. The relay drive circuit 28 and the relay 29 are arranged on the inner surface of the door 3 as the controller unit 10. The external output unit 33 of the relay 29 and the second connection unit 34 in the relay box 23 fixed to the outer surface of the safe body 2 are connected by an internal wiring 31 b for the signal line 21.

  The second connection portion 34 is also configured so that the other end of the signal line 21 can be easily disconnected outside the safe 1 when the safe 1 falls or is largely moved from the installation position. The other end of the signal line 21 (the side that is easily detached) is crimped or soldered to a U-shaped insertion piece type terminal 34a made of a flat metal plate (see FIGS. 8 and 9). The internal wiring 31b side (the side fixed to the relay box 23) is a terminal block 37 and a screw screw 38 on a support piece 36 erected on the base plate 35 in the relay box 23 (see FIG. 8). The bottom horizontal plate portion 35a of the base plate 35 is provided with a through hole 39 for pulling out the signal line 21 to the outside of the relay box 23, and a synthetic resin ring for preventing the signal line 21 from being damaged. The body 40 covers the peripheral edge of the through hole 39. Moreover, the inside of the relay box 23 is covered and protected by a removable cover body 40 (see FIGS. 6 to 8). The second connecting portion 34 may be a plug type connector similar to the first connecting portion 24.

  The controller unit 10 and the anti-theft sensor are arranged on the inner surface of the door 3 in the safe 1, and most of the internal wirings 31 a and 31 b from the controller unit 10 to the relay box 23 are stored in the safe body 2. The terminal portions of the internal wirings 31a and 31b provided in the space are configured to pass through the through passage 42 penetrating the wall (back plate 2a) of the safe body 2. In this case, in the embodiment, the plurality of internal wirings 31 a and 31 b are combined into a coiled wiring part 31, and the wiring part 31 is passed through a duct 43 fixed to the inner surface of the top plate 2 b of the safe body 2. The clearance space between the internal wirings 31a and 31b in the through passage 42 is filled with a fire spread material 44 having a thermal expansion property, so that external flames and heat do not enter the safe through the through passage 42 in the event of a fire. I am doing so.

  In the above configuration, at the start of normal use, the cover body 41 of the relay box 23 on the back of the safe body 2 is opened, the power line 20 is connected to the first connection portion 24, and the signal line 21 is connected to the second connection portion 34. Make sure it is connected to. Next, the A / C adapter 25 at one end of the power line 20 is connected to an outlet of an indoor commercial power supply, and one end of the signal line 21 is connected to the relay controller 26 connected to the monitoring device 22 of the contracted security company. As a result, power is supplied to the controller unit 10 via the power line 20, and the control system is activated. In a normal locked state, the relay drive circuit 28 is actuated by the normal output signal of the controller unit 10a to close the relay 29. Thus, since the terminals of the two internal wirings 31b are in a closed state (connected state), a circuit closed from the remote monitoring device 22 by the line network 27, the relay controller 26, the signal line 21, and the internal wiring 31b. Is formed. This state is monitored by the monitoring device 22 and it is determined that the safe 1 is normal.

  In order to properly open the door 3 from the state where the door 3 is normally closed and locked, a preset password is input to the input part of the numeric keypad type electronic lock 6. Receive a normal unlock signal. Next, by inserting a key into the cylinder lock 7 and turning it, the controller unit 10 releases the warning posture of various sensors 13, 14, 15, 17, which will be described later, and is unlocked. , The lock bolt 9 is retracted and the door 3 can be opened. Also in this case, since the normal signal is output from the controller unit 10a and the relay 29 is closed, the monitoring device 22 considers it normal.

  On the other hand, in the locked state, the various sensors 13, 14, 15, and 17 for theft prevention enter a warning state. Therefore, when an attack is applied to the safe 1, for example, the entire safe 1 is moved back and forth by a predetermined angle from an upright posture or When tilted left and right, the tilt sensor 13 detects and outputs a signal. The lock sensor 14 detects that the lock (cylinder lock) 7 has been subjected to a picking attack and outputs a signal. Further, the controller unit 6c detects an attack on the electronic lock 6 and outputs a signal. Similarly, the lock sensor 15 detects the lock / unlock state of the lock 7 itself and outputs a signal. In the handle sensor 17, the handle 8 detects a locking operation or unlocking operation, and in turn detects a door open / closed state, and outputs a signal. Thus, if it is in an abnormal state, the controller part 10a will output an abnormal signal, the relay drive circuit 28 will act | operate, and the relay 29 will open. As a result, since the terminal of the internal wiring 31b becomes an open circuit, the monitoring device 22 regards it as abnormal and dispatches a monitoring person from the security company to the site to check whether there is any damage. To do. In addition, the alarm device 11 in the safe 1 sounds to notify that it is abnormal.

  By the way, when an unauthorized person knocks down the safe 1 or moves it away from a normal position in order to take away the safe, the monitoring apparatus until one or both of the power line 20 and the signal 21 are disconnected. If it is not determined that 22 is in an abnormal state, emergency arrangements may be delayed. Therefore, when the safe 1 is knocked down or moved largely from a normal position as in the present invention, one or both ends of the power line 20 or the signal line 21 are connected to the connection parts 24 and 34 in the relay box 23. It is configured so that it can be easily removed. Thereby, the circuits of the network 27, the relay controller 26, and the signal line 21 are opened from the remote monitoring device 22, and it can be determined quickly and reliably that there is an abnormality.

  Further, in this way, one or both ends of the power line 20 and the signal line 21 are disconnected at the connection portions 24 and 34 of the relay box 23 outside the safe 1, so that the relay box 23 is removed from the controller unit 10 inside the safe 1. The internal wirings 31a and 31b up to the end of the internal wiring 31a and 31b are not damaged, such as being cut off. There is an effect of being able to return.

  As another embodiment, a backup power source 18 such as a lithium battery or an alkaline battery for supplying power to the alarm device 11 can be provided. The backup power supply 18 is provided independently of the anti-theft communication circuit so that the alarm device 11 sounds with the backup power supply 18. However, when the A / C power supply is energized, the backup power supply 18 is out of battery. Also, the circuit is configured such that the alarm device 11 is sounded by the A / C power source.

  When the voltage of the backup power supply 18 is locked to a predetermined value (at the time of consumption voltage) regardless of energization or non-energization of the A / C power supply, a consumption sound (for example, 30 seconds) sounds at the backup power supply 18 power supply. Let

  Regardless of whether the A / C power supply is energized or not, when the backup power supply 18 is disconnected, the consumable sound at the time of locking is not sounded. This notifies the user that the backup power supply 18 does not exist. Even when the backup power source 18 is not present, the circuit to the monitoring device 22 is closed, and the signal line 21 can be connected to the monitoring device 22 via the relay controller 26 and the network 27 so that monitoring is possible.

  Even when the A / C power supply is interrupted, it is not possible to determine whether the power line 20 or the signal line 21 is disconnected at the connection parts 24 and 34 or an unauthorized state at the time of disconnection, and an abnormal signal is sent to the monitoring device 22. It will never stop being reported.
