 As security glass having a detection means for detecting intrusion of a pirate, more security glasses have been employed than before. Japanese Patent Application Laid-Open No. 2001-126152 is one of the known techniques that is particularly close to the present invention. As schematically shown in FIG. 8, the "security glass" forms a conductive member capable of generating heat by energization on the surface of the glass main body 20, and electrodes 21, 22 provided on both edges of the glass main body. Lead wires 23 and 24, and a detecting unit 25 connected between the lead wires 23 and 24.

[0003] The "security glass" disclosed in Japanese Patent Application Laid-Open No. 2001-126152 discloses that the conductive member of the glass main body 20 is partially destroyed when a thief breaks the glass when intruding and tries to enter. Therefore, utilizing the change in the electric resistance between the two electrodes 21 and 22, the change in the electric resistance is detected by the detection unit 25 to confirm the breakage of the glass, thereby preventing the intrusion of a thief.

[0004]

[Problems to be solved by the invention]

 Although the above-mentioned known technique can surely detect the broken state of the window glass, it is sufficient to detect the change in the electric resistance value of the conductive member as described above, and the detection accuracy may be insufficient. . That is, there is a problem that the degree of reliability is low. In addition, if the glass is not completely destroyed at least, the detection of the electric resistance value becomes insufficient, and it is difficult to accurately detect the breakage of the glass. Further, structurally, the electrodes 21 and 22 are required as described above, and the structure becomes complicated and the cost increases accordingly. Further, in this conventional technique and other conventional techniques, there is a problem that the glass breakage cannot be detected until the glass is almost completely destroyed, and it takes time to detect the intrusion of a pirate or the like.

[0005] The present invention solves the above problems, and has a simple structure without using electrodes and the like. Even when the window glass is partially broken or partially damaged, for example. An object of the present invention is to provide a security glass structure capable of detecting an emergency state quickly and reliably detecting intrusion of a pirate and preventing the intrusion.

 Hereinafter, embodiments of the security glass structure of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment in which the security glass structure 1 of the present invention is provided on two window glasses 12 and 13 connected by a locking metal fitting 11. Of course, the glass to which the security glass structure 1 is applied is not limited to the window glass. As shown in FIGS. 1 and 2, the window glasses 12 and 13 include a glass body 14 and a frame 15 surrounding the periphery thereof. The glass body 14 is composed of a laminated glass 16 and a conductive film 17 covering the surface of the laminated glass 16 as shown in FIG. The laminated glass 16 is made of, for example, an ordinary float plate glass and a resin plate such as an interlayer film or a polycarbonate plate, which is not easily broken.

In the present embodiment, the conductive part 2, which is one of the main parts of the present invention, includes a cutting line 3 and lead wires 4, 5, and the like. Is divided, but a part 6 that is not divided is formed in a part thereof. That is, the glass body 14 is defined by the cutting line 3 at the point A 14A and the point B 14B, and the lead wire 4 is connected at one end to the point A 14A, and the lead wire 5 is connected at one end to the point B 14B. In addition, the cutting line 3 is formed in the vicinity of the vertical frame 15A of the frame body 15 having the locking hardware 11.

A sensor 7 is provided inside the frame. The other ends of the lead wires 4 and 5 are connected to the sensor 7, respectively. As described above, the portion A of the glass body 14 and the portion 14B of the glass body 14B conduct through the part 6 and are connected to the sensor 7 by the lead wires 4 and 5. However, in this state, the sensor 7 does not operate, and no detection signal is transmitted. Note that the sensor 7 is not special, but may be a sensor having a function of operating when not conducting to transmit a wired or wireless detection signal. The sensor 7 has a power supply inside, and has a frame 15 as described above. Any size can be used as long as it can be stored and arranged inside.

In the present embodiment, the emergency detection unit 8 includes the emergency display device 9 and the security mechanism / institution 10, but is not limited thereto. An example of the emergency display device 9 is a device that displays a warning, a light, a sign, or the like based on a detection signal from the sensor 7 and has a function of promptly and surely notifying the occurrence of an emergency to the outside. I just need. When a wireless detection signal is transmitted from the sensor 7, the emergency detection device 9 may be located at a place away from a certain building such as the window glass 12, 13 and can be arranged at a remote place. . The security mechanism / institution 10 is, for example, a security assurance company, police, or the like.

Next, the security operation of the security glass structure 1 of the present invention will be described with reference to FIGS. When a pirate (intruder) attempts to invade a house, the usual intrusion means is to destroy the portion near the lock fitting 11 as shown in FIG. In many cases, the lock fitting 11 is inserted to release the lock, and the windows 12 and 13 are opened to invade. In general, in order to form the space 18, an intruder first makes a cut line around the intruder, and works to break the glass inside the cut line slowly and gently over time. Therefore, it takes time until the space 18 is formed, and a sound is generated. As described above, in the case of the security glass structure of the related art, it takes time because various warnings are issued in a state after the space 18 is formed. In the case of the present invention, however, the instant at which the above-mentioned cut line is formed is taken. In this case, the conductive film 17 is cut, and the conduction of the portion 6 is lost, and the conduction between the A portion 14A and the B portion 14B of the glass body 14 is lost.

As described above, since conduction between the lead wires 4 and 5 and the sensor 7 is lost, the sensor 7 operates as described above and a detection signal is transmitted. This detection signal activates the emergency detection section 8 as described above, and, for example, the emergency display device 9 issues a loud alarm. This allows the intruder to give up and break away. Also, intruders are arrested by security mechanisms and agencies to ensure safety.

4 to 6 show another embodiment of the present invention. In the security glass structure 1a of this embodiment, the window glasses 12a and 13a are made of a laminated glass 16 without the conductive film 17 shown in FIG. 2 as shown in FIG. In this case, the conductive portion 2a includes a conductive wire 19 and lead wires 4a and 5a connected to both ends thereof. Of course, the lead wires 4a and 5a were connected to the sensor 7 disposed in the frame 15. With the above structure, the lead wires 4a and 5a can be conducted through the conductive wire 19, but the sensor 7 does not operate in this state.

Similar to the security glass structure 1 of the above embodiment, the initial process in which the window glass 12a, 13a having the security glass structure 1a of the present embodiment is broken by an intruder to form the space 18. In, the conductive line 19 is cut. Accordingly, the conduction of the lead wires 4a and 5a disappears, the sensor 7 operates, and a detection signal is transmitted from the sensor 7 and transmitted to the emergency display device 9 of the emergency detection unit 8 and the security mechanism / engine 10 as shown in FIG. You.

FIG. 7 shows a security glass structure 1 b according to another embodiment applied to a building or the like using the window glasses 12 and 13 shown in FIG. 1 and the like. In the security glass structure 1 shown in FIG. 1 and the like, the cutting line 3 is arranged only near the vertical frame 15A of the frame 15, but in the case of the present embodiment, the cut lines 3 Thus, the cutting lines 3a, 3b, 3c and 3d are arranged as described above. Here, the lead wires 4 and 5 are connected to the location A 14A and the location B 14B, and the leads 4 and 5 are connected to the sensor 7 disposed in the frame 15. With the above structure, when any space except for the center of the window glasses 12 and 13 is broken by an intruder to form the space 18, the conduction of the lead wires 4 and 5 is lost and the detection signal is transmitted from the sensor 7. It can prevent intruders from entering.

Although the security glass structures 1, 1a, and 1b of the three embodiments have been described above, the security glass structure of the present invention is not limited to the above, and is included in the same technical scope. It goes without saying that the present invention is also applied to the security glass structure of another embodiment.
