FIG. 9 is a block diagram of an embodiment of the anti-theft device for buildings according to the present invention.

The 7-transistor 2 of the sensor 6 is connected to the base of another transistor. The output of this Trannostuff is connected to a CPU of a computer as an example of control means 9 via an I10 interface 8.

On the other hand, the locking rock drive means 12 is a locking mechanism 70 that will be described later.
For example, as shown in FIG. It is a means of transmitting radio waves with a specific frequency. As long as there is no risk of interference with the frequencies of other buildings (for example, prevent interference by zoning or other methods), the frequency should be shared to some extent with the frequencies of other buildings.

Note that 101 is an antenna section, 102 is a transmitting section, and 103 is a control section that controls each of these sections.

Further, the receiver 11 is a means for receiving radio waves transmitted from the remote control transmitter 10. This receiver 11 is installed near a cylinder lock 100 in a building.
has been done. This receiver 11 is connected to the dual CPU 9 via an I10 interface 13.

Note that this locking mechanism driving means 12 does not necessarily have to be of a remote control type that transmits radio waves; for example, this locking mechanism driving means 12 can be directly inserted into a connector provided on the outside of a door of a building, etc. Alternatively, the driving means may be transmitted to the cylinder lock 100.

In this case, residents of the building may prevent the drive signal from being generated by inserting the locking mechanism driving means 12 into the connector part again, or the residents of the building may insert the locking mechanism driving means 12 into the connector part, or insert the locking mechanism driving means 12 into the connector part provided outside near the cylinder lock 100 of the building. By directly inserting the locking mechanism drive means 12, a drive signal is transmitted to the computer, which is stored in the computer.Then, when the building occupant opens the door, the remote control transmitter 10 turns it off. It may be configured to do so.

In this case, the locking mechanism 70 includes a drive section 72 and a drive section 72.
The projection of the locking piece 71 causes the recess 5 in the cylinder lock 100 to be closed.

Next, the operation of the above embodiment will be explained.

When residents of the building leave the building, the door is locked and a locking mechanism drive radio signal is transmitted by the remote control transmitter 10. The radio signal is transmitted to receiver 1
1 and input to the CPU 9.

On the other hand, in such a situation, a thief approaches the door of the building and inserts the fake door key or foreign object into the door cylinder lock 1.
00 and try to open the door. Since the sensor 6 is attached to the door cylinder lock 100 as described above, the insertion of the sensor 6 eliminates the penetrating state of the through hole X and blocks light. As a result, the sensor 6 detects the insertion of the foreign object. The ON output of that sensor 6 is I10
It is input to the CPU 9 through the interface 8. Therefore, the CPU 9 recognizes that the ON signal has been inputted from both the receiver 11 and the sensor 6, and outputs a locking mechanism drive signal to the locking mechanism 70 to operate the drive section 72, thereby causing the above-mentioned By fitting the locking piece 71 into the recess 50, rotation and unlocking of the inner cylinder 2 are prevented.

Therefore, even if a thief tries to open the door with a foreign object, he will not be able to unlock the door.

On the other hand, when residents of the building themselves open the door of the building using a door key, they release the locking mechanism drive signal using the remote control transmitter 10 they possess. As a result, when the door key is inserted into the cylinder lock 100, an ON signal is output from the sensor 6, but a locking mechanism drive signal is not input from the receiver 11, so the CPU 9
Since the locking mechanism drive signal is not output to the locking mechanism 70, there is no fear that the drive section 72 will operate.

Note that both the AND circuit in the embodiment shown in FIG. 10 and the series circuit in the embodiment shown in FIG. 11 operate in the same manner as the CPU 9 described above.

In the anti-theft device for a building according to the present invention, as shown in FIG.

The door key 200 or the like may be configured to be unable to be completely inserted by sensing that the tip of the door key 200 or other object is inserted and fitting the locking piece 71 into the recess 50. By configuring this, the theft of the negative layer can be prevented.

In the anti-theft device for a building according to the present invention, the locking mechanism may be of a form in which the driving part 72 and the locking piece 71 are separated, as shown in FIGS. As shown in the figure, since the driving portion 72 is provided in the locking mechanism 70, this device is compact and extremely easy to handle, such as when it is attached to a door or the like.

(g) Effects of the invention As is clear from the above description, the anti-theft device for a building according to claim 1 includes a locking sensor and a sensor that detects when a door key or other object is inserted into a door cylinder lock. and a locking mechanism driving means that outputs a signal to drive the mechanism, and when the sensor and the locking mechanism driving means are in the ON state, the locking mechanism is driven and the locking piece enters the recess, so that a thief cannot By preventing the inner cylinder from rotating and unlocking even if someone tries to open the building door using a structural door key, etc., it prevents theft of money, goods, credit cards, cash cards, etc. inside the building. We have it.

On the other hand, if a resident of the building opens the door themselves, the locking mechanism can be released by operating the locking mechanism driving means in advance, so there is no need to worry about the door being blocked.

In other words, in the present invention, when a thief unlocks the doorway, window, or door of a building such as a warehouse or house, the locking mechanism is activated before the key is unlocked. While the structure is such that a thief can stop the door lock simply by inserting a door key or other object into the door cylinder lock, the building resident, manager, or a person with permission from these persons must have the door locked in advance.
