Description

  The present invention is a surface grid that is attached to the outside of an opening of a window or the like in a building and is used to prevent intrusion from the outside. The present invention relates to a security surface lattice that can reliably prevent an intrusion from the outside by issuing an alarm.

  In order to prevent intrusion from the outside in the opening part of the window etc. in the building, a surface lattice is attached to the outside of the room, and such a surface lattice prevents crime from entering from the outside. Has contributed greatly for.

  As the above-mentioned surface lattice, a saddle-shaped surface lattice composed of a combination of a plurality of vertical and horizontal ridges and a frame-shaped surface lattice in which vertical members are arranged vertically, horizontally, diagonally, etc. in a peripheral frame are adopted. In general, such a surface lattice is assembled using an aluminum mold as a material.

Conventionally, as a method of improving the security function of the surface grid as described above, a human body sensor is attached at an appropriate position above the surface grid, and when a person approaches the surface grid, this is detected to prevent unlocking. The thing which made it do is proposed (for example, refer patent document 1).
JP 2002-180727 A

  As described above, the method of detecting the approach of a person by the human body sensor has a limitation in the detection range, and there is a risk that the surface grid is removed or destroyed in a portion outside the detection range. Since it is technically possible to process the human body sensor so that it does not operate, it is not sufficient in terms of safety.

  By the way, in a bowl-shaped surface grid composed of a combination of vertical and horizontal planes, or in a frame-shaped plane grid in which the brazing material is arranged vertically, horizontally, diagonally, etc. in the peripheral frame, this plane grid is destroyed and indoors. When trying to penetrate, the simplest method is to remove the frame located outside the room from the frame or frame fixed to the frame side due to the structure of the frame or frame grid. Invasion crimes in the indoor space are increasing.

  Specifically, a tool such as a screwdriver is inserted into the cross-joint part between the vertical and horizontal screws or the joint part of the saddle material to the peripheral frame to destroy this joint part, and the outdoor saddle material is removed. In order to create a condition for people to pass through, and then break open the glass, such as windows, to enter the room, such a rough crime can be relieved even if a face lattice is attached. It is a situation that cannot be done.

  Therefore, an object of the present invention is to provide a vertical plane in a vertical plane grid composed of a combination of vertical and horizontal planes, or a frame-shaped plane grid in which vertical frames are arranged vertically, laterally, diagonally, etc. in a peripheral frame. When the joints between the reeds and the frame and the frame are destroyed, this is electrically detected and an alarm is issued, and a highly safe crime prevention face lattice that can prevent crimes entering from the outside in advance. It is to provide.

  In order to solve the above-described problems, the present invention provides a plane lattice in which a downspout and a recumbent are combined, and the crossing of the recumbent line and the recumbent is inside one of the downspout and the recumbent side. A switch is provided to detect when the vertical and horizontal joints are uncoupled, and a power source and a sound generator electrically connected to the switch are provided at appropriate positions on the surface grid. A configuration is adopted in which the sound generator produces a sound when the connection between the heel and the side is broken and the switch detects this.

  The switch provided inside one of the above-mentioned downside and sideways is normally closed and is opened by bringing the terminal into contact with the other side of the downside and downside. A plurality of switches are arranged so as to be located in a portion, and each switch is connected in parallel and connected to a power source. When the downside and downside coupling is released and one of the switches is closed, the sound generator is energized. It is possible to generate sound, or to have a structure in which one or both of the power source and the sound generator are arranged outside the surface lattice.

  In another aspect of the invention, in the peripheral frame and a surface lattice formed by providing a saddle material inside the peripheral frame, the peripheral frame and the saddle material are combined inside either the peripheral frame or the saddle material. A switch that is arranged to be located at a portion and detects when the peripheral frame and the saddle material are uncoupled, and a power source and a sounder that are electrically connected to the switch are provided at appropriate positions on the surface grid, and the peripheral frame When the switch is detected, the sound generator produces a sound when the combination of the wood and the wood is broken.

  A switch provided inside one of the peripheral frame and the saddle is normally closed and is opened by bringing the terminal into contact with the other of the peripheral frame and the saddle. A plurality are arranged so that they are located in a part, each switch is connected in parallel and connected to the power source, and when the switch is closed when the peripheral frame and the saddle are uncoupled, the sound generator generates sound by energization Alternatively, either one or both of the power source and the sound generator may be arranged outside the surface grid.

  Here, a plurality of switches located in the same saddle material or the peripheral frame are connected in parallel using the wiring board accommodated in the saddle material or the peripheral frame. Connect with cords stored in the frame and surrounding frame, and connect the switch, power supply, and sound generator using the wiring board and lead wires, and cross-joint parts of the vertical and horizontal planes and the frame and the frame If the connection part of the sound is broken, the switch is closed and a current flows to the sound generator, and an alarm is issued to prevent a crime that enters from the outside.

  According to the present invention, the switch is provided in the crossing portion of the vertical gutter and horizontal gutter in the plane lattice and the coupling portion of the peripheral frame and the gutter material, and the power source and the sound generator are connected to the switch. The switch detects this when it breaks the joint part of the frame and the joint part of the peripheral frame and the saddle, and the sound generator will pronounce it. It is possible to prevent crimes that enter from the outside and to provide a security grid with excellent safety.

  In addition, since the switch, the power source, and the sound generator are housed inside the saddle member in the face grid or the joint portion between the peripheral frame and the saddle member, its presence is not known at all from the outside of the face grid. At the same time as it does not impair the aesthetic appearance, it becomes difficult to process in advance so as not to operate the switch, power supply, sound generator, etc. from the outside, and it is possible to ensure safety by the security grid.
