  2. Description of the Related Art Conventionally, a crime prevention device (for example, see Patent Document 1) that issues an alarm for breaking glass windows and the like, and a crime prevention device that issues an alarm for window glass or the like (for example, Patent Document 2) have been proposed. reference).

JP 2003-36483 A (summary) JP 2006-236322 A (summary)

  However, although the security devices proposed in Patent Document 1 and Patent Document 2 can issue an alarm when the window glass or the like is broken, the intruder holds the lock portion after the window glass or the like is broken. It had the problem that it could be unlocked easily. Moreover, since the crime prevention apparatus proposed in Patent Document 1 and Patent Document 2 is difficult to visually recognize from the outside of a building such as a house, it has a problem that the crime deterring power is small.

  In view of the above situation, an object of the present invention is to provide a crime prevention device in which an intruder cannot easily unlock a lock even if a window glass or the like is broken.

  In order to achieve the above object, a security device according to the present invention is a security device installed in the vicinity of a lock part, comprising a movable part and a lock release part. A first state that does not inhibit unlocking and a second state that inhibits unlocking of the lock part can be taken, and if the lock is not released by the lock release part, The first state cannot be transferred.

  In addition, a security sensor for detecting an abnormality of the detection target is provided, the abnormality detection using the security sensor is not performed in the first state, and the security sensor is used in the second state. Anomaly detection may be performed. Furthermore, you may provide the said security sensor in the said movable part.

  Moreover, only one board | substrate which mounts the electronic component containing the said security sensor may be provided, and the said board | substrate may be covered with a housing | casing.

  According to the security device according to the present invention, even if an intruder tries to unlock the lock part, the second state inhibits the unlocking of the lock part. Furthermore, by making it into the first state, it is possible to release the inhibition of the unlocking of the lock part, but if the lock is not released by the lock release part, the state shifts from the second state to the first state. Therefore, it is difficult for an intruder to put the security device according to the present invention into the first state.

<First Embodiment of the Present Invention>
FIG. 1 shows an exploded perspective view of the security device according to the first embodiment of the present invention, and FIG. 2 shows an exploded side view of the security device according to the first embodiment of the present invention.

  The security device according to the first embodiment of the present invention includes an upper case 1, an intermediate case 2, a lower case 3, a left upper arm 4L, a left lower arm 5L, a left lens cap 6L, and a left sensor substrate 7L. A right upper arm 4R, a right lower arm 5R, a right lens cap 6R, a right sensor board 7R, a circuit board 8, a lock release switch 9, and springs S1 and S2. The lower case 3 can be attached to the inner surface of the window frame, for example, with a double-sided adhesive tape.

  The left lower arm 5L and the left sensor board 7L are screwed to the left upper arm 4L, and the left upper arm 4L and the left lower arm 5L store the left sensor board 7L. Further, the left lens so that the infrared rays focused by the left lens cap 6L are incident on the left pyroelectric sensor 17L (see FIG. 6) mounted on the left sensor substrate 7L through the opening of the left lower arm 5L. The cap 6L is set in the opening of the left lower arm 5L. The left upper arm 4L, the left lower arm 5L, the left lens cap 6L, and the left sensor substrate 7L constitute a left arm portion.

  Similarly, the right lower arm 5R and the right sensor board 7R are screwed to the right upper arm 4R, and the right upper arm 4R and the right lower arm 5R store the right sensor board 7R. Further, the right lens is so arranged that the infrared rays focused by the right lens cap 6R enter the right pyroelectric sensor 17R (see FIG. 6) mounted on the right sensor substrate 7R through the opening of the right lower arm 5R. The cap 6R is set in the opening of the right lower arm 5R. The right upper arm 4R, the right lower arm 5R, the right lens cap 6R, and the right sensor substrate 7R constitute a right arm portion.

  The left arm portion and the right arm portion are respectively screwed to the middle case 2 so as to be rotatable. Further, since the gear portion of the left upper arm 4L and the gear portion of the right upper arm 4R are engaged with each other, the left arm portion and the right arm portion rotate in conjunction with each other.

  Further, the lower case 3 is screwed to the middle case 2, and the lower case 3 and the middle case 2 store the circuit board 8 and the lock release switch 9. The lock release switch 9 is supported by the lower case 3 via a spring S1.

  The button battery 10 can be set to the button battery installation location 8 </ b> A of the circuit board 8 from the opening 2 </ b> A (see FIG. 3) of the middle case 2. Further, the button battery 10 can be replaced by removing the upper case 1 from the middle case 2.

  When the lock release switch 9 is not pushed to the lower case 3 side, the locking portion 9A (see FIG. 4A) of the lock release switch 9 is as shown in FIG. 4A from the opening 2B (see FIG. 3) of the middle case 2. Since it protrudes to the upper case 1 side and abuts on each step portion 5A (see FIG. 1) of the left lower arm 5L and the right lower arm 5R, the left arm portion and the right arm portion are prevented from opening. Therefore, when the lock release switch 9 is not pushed to the lower case 3 side, a state as shown in FIG. 5A (a first state that does not hinder the unlocking of the lock portion) is obtained.

On the other hand, when the lock release switch 9 is pushed to the lower case 3 side, the locking portion 9A of the lock release switch 9 does not protrude to the upper case 1 side as shown in FIG. And since it does not contact each step 5A (see FIG. 1) of the right lower arm 5R, the left arm and the right arm are opened by the restoring force of the spring S2 (see FIG. 3). Therefore, when the lock release switch 9 is pushed to the lower case 3 side, a state as shown in FIG. 5B (a second state in which the unlocking of the lock part is hindered) occurs, and Inhibits unlocking. In order to shift from the state shown in FIG. 5B to the state shown in FIG. 5A, it is necessary to close the left arm and the right arm while pushing the lock release switch 9 to the lower case 3 side.

  Here, the electrical configuration of the security device according to the first embodiment of the present invention is shown in FIG. In the crime prevention device according to the first embodiment of the present invention, the pyroelectric sensor interface circuit 11 including the A / D conversion circuit, the control unit 12, the amplifier 13, the selection circuit 14, the signal processing circuit 15, and the notification unit. 16 and the switch 19 are mounted on the circuit board 8, the left pyroelectric sensor 17L and the left ultrasonic microphone 18L are mounted on the left sensor board 7L, and the right pyroelectric sensor 17R and the right ultrasonic microphone 18R are mounted. It is mounted on the right sensor board 7R.
