Description Security system for multi-layer window materials and multi-layer window materials

The present invention relates to a security system for a multi-layer window material and a multi-layer window material used for a multi-layer window material including two window plates arranged to face each other with a predetermined gap therebetween. Background art

In recent years, burglars, robbers, etc. have frequently entered the houses, shops, offices, etc. by breaking windows, etc. Various security systems have been proposed.

For example, when an open / close sensor is attached to a window material and a burglar or a robber opens the window material, a sensor that detects the opening of the window material is known (Japanese Unexamined Patent Publication No. 6-16262). 3 5 4). Also, if a small vibration sensor is attached to the window material and a burglar or a robber opens the window material or breaks the window plate, it is known that the vibration sensor detects the vibration of the window material at that time. (Japanese Unexamined Patent Publication No. 2002-190900). It is also known that a sound collecting microphone is attached near the locking handle of the window frame, and when a burglar or a robber cuts the window plate, the sound collecting microphone detects the cutting sound (Japanese patent). Open 2 0 0 1 — 3 0 7 2 3 8). Furthermore, a protective sheet is attached around a lock on a window plate to prevent the window plate from breaking (Japanese Patent Application Laid-Open No. 2003-208826). Gazette).

By the way, in recent years, a multi-layer window material including two window plates arranged so as to face each other with a predetermined gap has been widely used. According to this, two sheets The heat insulating effect is improved by the window plate as compared with the conventional single window plate. In particular, when the gap between the window plates is evacuated, the heat insulating effect can be further improved. Also, such a multi-layer window material is generally applied with the above-described crime prevention system.

However, in the first security system described above, if the window plate is broken without moving the window material, the open / close sensor cannot detect intrusion such as a burglar or a robber. Further, in the above-described second security system, if the window plate is forcibly prevented from vibrating by a glass cutter or the like, the vibration sensor cannot detect intrusion such as a burglar or a robber. Further, in the above-described third security system, if the window plate is similarly cut by a glass cutter or the like so that no sound is produced, the sound collecting microphone cannot detect intrusion of a burglar or a robber. Furthermore, the above-mentioned fourth security system only prevents the window board from breaking, and does not detect any intrusion such as a burglar or a robber.

Therefore, conventional security systems, including those described above, have a problem that it is difficult to reliably detect intrusion of a burglar or a robber through a window.

The present invention has been made in view of the above-mentioned problems, and is directed to a multilayer window material including two window plates arranged so as to face each other with a predetermined gap therebetween. Disclosure of invention _c for the purpose of providing a security system for a multi-layer window material and a multi-layer window material capable of easily and reliably detecting the intrusion of a burglary or the like.

In order to achieve the above-mentioned object, the present invention includes two window plates arranged so as to face each other with a predetermined gap therebetween, and the gas pressure in the gap between the window plates is constant. Security system for multi-layer window material used for multi-layer window material kept in

Pressure detecting means for detecting a change in gas pressure in a gap between the window plates And alarm output means for outputting an alarm when the pressure detection means detects a change in gas pressure in the gap between the window plates.

According to this, when at least one of the window plates of the multilayer window material is broken, the gap between the window plates communicates with the outside air, and the pressure of the gas in the gap between the window plates changes. Therefore, the pressure detecting means can detect a change in the pressure of the gas, and the alarm output means can output an alarm in accordance with the detection. For this reason, not only when a burglar or a robber breaks the window plate as it is, but also when the window plate is cut with a special power cutter or the like without vibrating or cutting noise, It is possible to easily and reliably detect intrusion such as robbery.

Further, it is preferable that the pressure detecting means is provided with a gas extraction hole communicating with a pressure extraction hole formed in the window plate.

According to this, the gas in the gap between the window plates can be extracted from the gas extraction hole of the pressure detection means via the pressure extraction hole of the window plate. The pressure extraction hole of the window plate may be newly formed in the window plate, or an existing gas extraction hole already formed in the window plate may be used.

Further, the multi-layer window material is provided so as to be openable and closable with respect to a window edge material provided in a window hole of a wall,

One of the male member or the female member of the magnet plug connected to the pressure detecting means is provided on the multi-layer window member, and the other of the male member or the female member of the magnet plug connected to the alarm output means is provided. The male member and the female member of the magnet plug are provided on the window edge member, and when the multilayer window member is closed with respect to the window edge member, the male member and the female member of the magnet plug come into contact with each other in an energizable state. Is preferred.

According to this, when the multilayer window material is closed with respect to the window edge material, the male member and the female member of the magnet plug come into contact with each other in a state where they can be energized. The pressure detecting means and the alarm output means can also be energized. For this reason, the security system can be easily applied to a multi-layer window material that can be opened and closed with respect to the window edge material.

Further, it is preferable that the alarm output means outputs an alarm when the energized state of the male member and the female member of the magnet plug is cut off.

According to this, even if a burglar or a burglar opens the window material without breaking the window plate, the intrusion of a burglar or a burglar from the window can be detected easily and reliably.

In the magnet plug, it is preferable that at least one of the male member and the female member is biased by an elastic member in a direction of approaching and separating from the other contact terminal.

According to this, when the multilayer window material is closed with respect to the window edge material and the male member and the female member of the magnet plug come into contact with each other, the distance between the contact terminals of the male member and the female member of the magnet plug and The displacement is absorbed, and the pressure detection means and the alarm output means can be reliably energized. The elastic member includes a spring, a spring, rubber, and the like.

Preferably, the gap between the window plates is kept in a vacuum state. According to this, the heat insulating effect of the multilayer window material can be improved, and a change in the gas pressure in the gap between the window plates can be more easily and reliably detected. The vacuum state includes not only a complete vacuum state in which the gas pressure in the gap between the window plates is 0, but also a state in which the gas pressure is extremely low and close to a complete vacuum state.

The alarm output means outputs an alarm to a computer of a security company via a network when the pressure detection means detects a change in gas pressure in the gap between the window plates. It is preferred that this be done. According to this, even security companies can detect intrusions such as burglars and robbers, and the reliability of the security system can be further improved.

Further, the multi-layer window material according to the present invention includes two window plates arranged so as to face each other with a predetermined gap therebetween, and the gas pressure in the gap between the window plates is kept constant. And a pressure detecting means for detecting a change in gas pressure in a gap between the window plates.

It is held by the above-mentioned window frame (11) via a holding member (14) so as to face each other with a predetermined gap (13) (for example, 0.2 mm).

As shown in FIG. 3, the window plates (12) and (12) are provided with spacers (15) between the peripheral edges (13) and the gaps (1). A plurality of micro-spacers (16) having a small diameter (for example, 0-mm) are arranged at equal intervals in each part of (3), and these spacers (15) and micro-spacers (16) are arranged at equal intervals. Thus, the distance of the gap (13) is kept constant.

A small-diameter pressure outlet (12a) is formed in the lower right corner of the window plate (12) (12). The pressure extraction hole (12a) is used for extracting the gas pressure in the gap (13) between the window plates (12) and (12) and for mounting the pressure detection device (2). A spiral is formed on the inner peripheral surface on the mounting side.

A small-diameter gas extraction hole (12b) is formed in the window plate (12) above the pressure extraction hole (12a). The gas vent hole (12b) is provided with the gas (13) in the gap (13) between the window plates (12) and (12). This is a hole for extracting the air (in the form, air). When almost all the air in the gap (13) is extracted from the gas extraction hole (12b), the gap (13) is in a vacuum state ( (Including the state close to vacuum). As described above, when the gap (13) between the window plates (12) and (12) is in a vacuum state, the heat insulating effect of the multilayer window material (1) can be improved.

Further, (17) is a protective cap fitted into the gas vent hole (12b), and air is extracted from the gas vent hole (12b) and the gap (1 3) After the vacuum is established, the gas vent hole (12b) is closed. In order to improve the durability of the window plates (12) and (12), when inserting the protective cap (17) into the gas vent hole (12b), the protective cap (17) should be inserted. It is preferable to form the gas vent hole (12b) so that the depth does not exceed 1Z2 of the thickness of the window plate (12) (12).

The pressure detecting device (2) includes a rectangular parallelepiped casing (21) and a pressure switch (22) housed in the casing (21) in a lateral direction.

By being inserted, it is attached to the window plate (12).

The function of the pressure switch (22) will be specifically described.

In the pressure switch (22), the connection port (22g) is connected to the gap (13) between the window plates (12) and (12) via the pressure extraction hole (12a). The gas pressure in the gap (13) can be taken in. At this time, if the gap (13) between the window plates (12) and (12) is kept in a vacuum state, the state between the C and NC terminals of the microswitch (22a) is in an electrically conductive state. Become.

When at least one of the window plates (12) and (12) is broken, the vacuum state of the gap (13) is broken, the pressure of gas increases, and the gap (13) The pressure of the gas at the port enters the connection port (22 g) through the pressure outlet (12a) and acts on the diaphragm (22e) and the link plate (22f) to regulate. The compression spring (22d) is compressed, and the link board (22f) switches the switch by pressing the pin button of the microswitch (22a). At this time, the microswitch (22a) is energized between the C and NO terminals.
