Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a security material used by being attached to a wall of a building.

[Background technology]

2. Description of the Related Art To protect buildings where large amounts of money are handled, such as financial institutions and stores, various security devices are used to detect people illegally entering the building. Currently, commonly used security devices include devices that use infrared rays and ultrasonic waves, television cameras, and devices that detect body temperature, vibrations, and breaking sounds, and are placed mainly at building entrances and windows. ing.

For this reason, in recent years, illegal intruders have been breaking down the walls of buildings. Since the walls of buildings are inevitably large, it is not possible to easily install sufficient security devices. In other words, the wall is a blind spot in terms of security measures for thieves trying to break into the area.

Apart from the above, the conventional crime prevention devices described above have a considerably high sensitivity in order to increase the crime prevention effect, and are easily susceptible to similar conditions, so there is a problem that they are prone to malfunction. Some crime prevention devices can be seen from the outside, making customers aware that they are being monitored, and there is also the problem of creating bad feelings among customers. If it is visible, it becomes easier to break through the defenses, which poses a security problem.

In order to solve the above problem, the applicant has developed a crime prevention material that is used for walls and the like and activates an alarm when the wall or the like is destroyed. This crime prevention material is formed into a sheet or plate shape, making it easy to construct walls, ceilings, floors, etc., and a conductive wire for destruction detection is routed around the base material. These conductive wires are spaced far enough apart that no one can enter them, and if they break, an electrical signal will be sent and an alarm will be activated.

If a crime prevention material configured in this manner is used, the crime prevention effect of the building in which it is installed will be extremely high, and false alarms and malfunctions will be less likely to occur. Moreover, the appearance of the building is not impaired, and the installation state of the security material is not noticed.

However, when this crime prevention material is attached to a wall or the like, there is still a problem to be solved regarding the means for connecting the conductor wires wrapped around the crime prevention material to an external electrical device (for example, an alarm, etc.). In addition, the base material to be shaped into a sheet or plate may be made of a material that is susceptible to heat, or may be extremely thin. Soldering such a base material is extremely difficult, and there is also the problem that wire connections cannot be made. Furthermore, the base material is not limited to only a flat surface, but also has a curved surface or an uneven surface, and there are also problems in the method of forming conductive wires on these materials.

[Purpose of the invention]

This invention was made in view of the above circumstances, and is extremely easy to connect with external electrical equipment (for example, an alarm), has a high crime prevention effect, and prevents false alarms and
A crime prevention mechanism that is unlikely to malfunction and whose installation status cannot be noticed from the exterior can be installed very easily on the walls of buildings with large areas, and can be installed on curved surfaces, etc. The purpose is to provide crime prevention materials that can be used.

[Disclosure of the invention]

In order to achieve the above object, the present invention provides a crime prevention material in which a conductive wire for destruction detection is provided on a base material, the conductive wire is formed by thermal spraying of a conductive material, and the terminal of the conductive wire and The gist of this product is a crime prevention material that is characterized by having terminal portions formed in certain locations. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows the appearance of one embodiment of the security material according to the present invention, viewed diagonally from above. As shown in the figure, this security material 1 has conductor wires 3 formed by thermally spraying a conductive material such as metal onto the surface of a sheet (base material) 2 made of synthetic resin such as polyethylene, polypropylene, or polyvinyl chloride. are doing. It is then used by being covered with a covering material made of the synthetic resin, paper, or the like, if necessary.

An insulating plate made of wood or the like may be used instead of the sheet 2. The conductive wires 3 are wound continuously and evenly on the surface of the sheet 2 in a meandering manner while maintaining a spacing that is large enough that a human body cannot pass through. Note that the wiring pattern shape of the conducting wire 3 is not limited to the above-mentioned one, and various shapes can be considered depending on the place of use.

Since the conducting wire 3 is formed by thermal spraying as described above, it can be made as thin as about 0.01 to 0.50 wa. That is, the conducting wire 3 can be made sufficiently thin. Therefore, the work of sandwiching the conductive wire 3 between the sheet 2 and the covering material etc. becomes very easy, and various crime prevention materials can be obtained. Compared to the case where enameled copper wires, optical fibers, etc. are stretched over a base material such as the sheet 2, the number of man-hours is reduced, and the manufacturing cost of this security material 1 can be lowered. The conductor 3 is
Since it is formed by a thermal spraying method, the surface shape of the base material is not limited to a flat surface, but may be a curved surface, an uneven surface, a bent surface, etc., and also has excellent conductivity.

This security material 1 is used, for example, in the following manner. As shown in FIG. 8, the wall 5 of the room 4.
6. Attach security material 1 to 7.

When a thief destroys any of the wall surfaces 5, 6, and 7, the security material 1 is also destroyed at the same time. The conductive wire 3 is formed in complete contact with the sheet 2 serving as the base material. Therefore, when the crime prevention material 1 is destroyed, the conducting wire 3 is also surely broken.

By making it possible to detect the breakage of the conductor 3, this illegal intrusion by thieves can be reliably detected. That is, a minute current is passed between both ends of the conducting wire 3, and a signal generating means that issues an electric signal when the minute current stops flowing, and an alarm that issues an alarm upon receiving this signal are connected. When the wall surfaces 5, 6.7 are broken and the conducting wire 3 is broken as described above, the flow of the minute current ceases. Therefore, a signal is emitted from the signal generating means, and the alarm machine that receives this signal issues an alarm.

As shown in FIG. 2, the crime prevention material 1 is provided with a terminal portion 8 at the end of the conductive wire 3.

The terminal portion 8 is thermally sprayed with a conductive material in the same manner as the conductive wire 3, and is formed into a disk shape larger than the width of the conductive wire 30. The thickness of this terminal portion 8 is approximately the same as that of the conducting wire 3. In this way, if the surface area of the terminal of the conducting wire 3 is made larger, it becomes easier to connect the wiring for flowing the minute current to the conducting wire vA3. That is, since the wiring installation of the terminal part 8 requires a large area, soldering the wiring makes the work easier, and the security material 1 and the external electrical equipment (for example, the signal generating means, the alarm) can be connected easily. This makes it easier to connect the wires.

3 to 7 show that instead of the terminal portion 8 shown in FIGS. 1 and 2, a conductor having conductivity is embedded in the base material or is attached to the base material. The terminal part formed by the process is removed. The security materials shown in Figures 3 to 7 include a base material 15 made of an insulating material such as wood.
The conductive wire 3 is wrapped around the surface of the security material 1 in the same manner as the security material 1.

FIG. 3 shows a crime prevention material 9 in which a rectangular parallelepiped-shaped conductor 16 is embedded to form a terminal portion 19 at the end of the conductive wire 3. In this terminal portion 19, the upper surfaces of the base material 15 and the conductor 16 are flush with each other, and the terminal of the conductive wire 3 is formed and connected to the upper surface of the conductor 16 by thermal spraying. The width of the conductor 16 is sufficiently larger than the width of the conductor 3, similar to the terminal portion 8 shown in FIG. (Therefore, it is extremely easy to connect to external electrical equipment, etc.).

In the security material 10 shown in FIG. 4, a conductor 17 having a trapezoidal cross section is embedded in the base material 15 in place of the conductor 16 constituting the security material 9 shown in FIG. It becomes. In this way, when the conductor is formed into a trapezoidal shape, it is difficult to fall off from the base material 15, resulting in a more firmly fixed terminal. This terminal section 20 is, of course,
It has the same effect as the terminal portions 19 and 20 shown in FIGS. 2 and 3.

FIG. 5 shows the base material 15 at the terminal position of the S line 3.
The crime prevention material 11 is provided with a conductor 18 in the shape of a rectangular parallelepiped attached to the surface thereof to form a terminal portion 21. This conductor 18 has a screw hole 26 that penetrates from its front surface to its back surface.
is provided.

A lead wire of an external electrical device or the like is wound around a screw (not shown), and then this screw is screwed into the screw hole 26.

With this configuration, soldering work is not required, the wiring can be easily connected, and the wiring is more reliable. As shown in the security material 12 shown in FIG. 6, a synthetic resin plate 27 is connected to the conductor 18 and the base material 1.
5 may be fixed so as to be sandwiched between them. This plate 27 may be provided with a round hole in the place where the screw hole 26 of the conductor 18 will be (or a threaded hole may be provided along with the conductor 18. Even if the terminal portion 22 is formed in a similar manner, the same effect as the terminal portion 21 shown in FIG. 5 can be obtained.Plate 2
If 7 is provided with a tapped hole, the screw 28 can be screwed in more deeply, making the connection more reliable.

In the security material 13 shown in FIG. 7, a plate-shaped conductor 25 bent into a U-shaped cross section is attached to the top surface of the base material 15 at the end of the conducting wire 3 to form a terminal portion 23. This conductor 25
A screw hole is provided in the center of the top surface. screw 28
A lead wire from an external electric device or the like wound around the holder is screwed by screwing the screw 28 into the screw hole.

If the screws 28 or the like are used to connect the wires in this way, time-consuming work such as soldering is not required, which is very convenient.

In this way, if the width of the terminal portion is made sufficiently larger than the width of the conducting wire, connection by soldering or the like becomes very easy. If the lead wire or the like is screwed in with a screw or the like, it can be fixed more easily and more reliably.

Note that the terminal portion of the security material is not limited to the above shape. Various shapes of the conductor constituting this terminal portion can be considered. In addition to screws and solder, a spring or the like may be used to connect the wires, and the wires may be sandwiched between the wires. The fixing method may be freely selected.

The base material does not have to be flat, and connection work with external electrical equipment (for example, an alarm) becomes very easy. Moreover, it has a high crime prevention effect and is unlikely to cause false alarms or malfunctions. Even from the outside, the installation state of this security material cannot be noticed. A security mechanism can be easily installed without modifying the walls of a building.
