BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening and closing type surface grating attached to a window opening, and more particularly to an alarm crime prevention device for a surface grating that detects an alarm when the surface grating is unexpectedly opened and gives an alarm. Regarding

2. Description of the Related Art Generally, a plane lattice is fixedly installed for the purpose of crime prevention, but in the case of a fixed type, when an emergency such as a fire occurs, there is a possibility that it may be hindered from escaping to the outside and may cause a disaster. From the above, the above-mentioned surface lattice is configured to be openable and closable,
It is considered that the plane lattice is locked by a locking device that can be unlocked only from the indoor side. However, in such a configuration, since there is usually no opportunity to open the area lattice,
Once an emergency situation such as a fire occurs, the person gets upset and often cannot think of the existence of the lock or take time to unlock it. I am also concerned about the situation that cannot be fulfilled. Therefore, the applicant of the present invention has previously tried to open the plane lattice and escape to the outside of the room in the event of an emergency such as a fire, and an outsider tried to enter the room by opening the plane lattice. Occasionally, a plane lattice was proposed in which a buzzer was activated by a switch mechanism to give an alarm and an alarm crime prevention device capable of notifying the presence of an intruder was incorporated (Japanese Utility Model Laid-Open No. 2-51688). According to this, the plane lattice can be easily opened by an operation corresponding to the instinctual movement of a person who has fallen into an emergency, and there is also a crime prevention effect.

[0003]

However, in the above-mentioned conventional alarm security device for the plane lattice, the switch mechanism for actuating the buzzer has a contact piece provided on the fixed crosspiece side and a contacted piece provided on the movable side face lattice body. Since it is a contact operation method that has parts, the structure becomes complicated, the assembly to the fixed crosspiece and the surface lattice main body becomes very troublesome, the cost is high, and the area lattice is to be installed outdoors. However, since the switch mechanism itself is not operated frequently, there has been a problem that the contact piece and the contacted portion are easily rusted to cause a contact failure and are likely to fail. In addition, with this alarm crime prevention device, the buzzer always operates when the surface lattice is opened, so an alarm is issued even when the surface lattice is opened in order to take things in and out through the window opening. There was the inconvenience of being emitted. An object of the present invention is to provide an alarm / crime prevention device in an area lattice which can solve the above problems.

[0004]

The structure of the present invention for achieving the above object will be described with reference to the drawings corresponding to the embodiments. In the present invention, a fixing bar 4 fixed to a window opening 3 is provided.
A switch main body 14 for holding an off state when receiving a magnetic force in a surface lattice including a surface lattice main body 5 movably attached to the fixed crosspiece 4 and capable of opening and closing the window opening 3.

Buzzer regardless of the power supply 18 and the switch body 14.
17 alarm switch 19 for operating the take power switch 20 the switch mechanism 2a made by arranging the mounting substrate 11, the fixed rail 4 by the mounting substrate 11
In addition , the alarm crime prevention device 2 is configured by providing a magnet member 2b for applying a magnetic force to the switch body 14 at a position facing the switch body 14 of the surface lattice body 5 in the closed state.

[0005]

When the surface lattice body 5 is moved to open the surface lattice 1, the magnet member 2b is separated from the switch body 14 of the switch mechanism 2a, so that the switch body 14 is turned on and the buzzer 17 operates. Therefore, even if an outsider accidentally opens the surface lattice 1 and tries to enter the room, it can be reliably detected and an alarm can be issued. Also,
In the event of an emergency such as a fire that requires an emergency escape to the outside, the plane lattice main body 5 may be moved to open the plane lattice 1 in the same manner as described above, whereby the window lattice 3 escapes to the outside. In addition, the operation of the buzzer 17 can notify the surroundings of the occurrence of an emergency.
Further, in the case where an object is to be taken in and out through the window opening 3, it is sufficient to turn off the power switch 20 and then move the plane lattice main body 5 to open the plane lattice 1, whereby the buzzer is activated. Things can be taken in and out without activating 17 Furthermore, crimes, for example indoors

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 5 and 6 show a state in which an alarm crime prevention device 2 according to an embodiment of the present invention is attached to a surface lattice 1, which is the upper and lower edges of a window opening 3. A pair of upper and lower fixed bars 4, 4 fixed to the outdoor side of the building body along
It is composed of a surface lattice main body 5 mounted on both of the fixed bars 4 so as to be horizontally movable. Reference numeral 6 is a window shoji provided in the window opening 3.

As shown in FIGS. 1 to 3, the fixed bar 4 has a tubular shape with a substantially oval cross section, is made of an aluminum extruded material, and has concave grooves 8 and 9 on both indoor and outdoor sides thereof. Are formed. In addition, the surface lattice main body 5 has a groove 8 on the outdoor side.
Support bars 5a, 5a made of an aluminum extruded mold material that are freely inserted only horizontally and a plurality of vertical bars 5b, 5b made of an aluminum extruded mold material, which are arranged at predetermined intervals between the upper and lower support bars 5a. It consists of Further, the alarm / security device 2 includes a switch mechanism 2a provided on the indoor side of the upper fixed rail 4 and the upper support rail 5a facing the switch mechanism 2a.
It is composed of a magnet member 2b provided inside.

The switch mechanism 2a is composed of the following. That 11 is a mounting substrate made of an electrically insulating material disposed on the side surface of the indoor side of the upper fixed rail 4, the preparative
Substrate 11 with attachment and connecting plate 12 fitted in the inner groove 9
Are fixedly connected to the fixed rail 4 by integrally connecting them with screws 13 with the groove opening edge portions 4a, 4a sandwiched therebetween. The mounting substrate 11 may be attached to the fixed rail 4 with a double-sided adhesive tape. 14 is the mounting board 1
1 is a switch main body which is disposed on the back surface of the connection plate 1 and which is loosely fitted into the indoor concave groove 9 through the through hole 15 of the connecting plate 12.
It is generally called a magnet switch, and keeps an off state when receiving a magnetic force from the outside.

On the surface of the mounting board 11, a buzzer 17 that operates when the switch body 14 is in an ON state,
A power source 18 composed of a dry battery, an alarm switch 19 for operating the buzzer 17 regardless of the switch body 14 in an emergency, and a power source switch 20 are provided. These are as shown in FIG. The circuit is configured. Reference numeral 21 denotes an exterior case that is detachably attached to the mounting board 11, and has an opening 22 of the case 21.
From 23, the operation parts 19a and 20a of the alarm switch 19 and the power switch 20 are exposed to the outside.

The magnet member 2b is made of a permanent magnet and is provided at a position facing the switch body 14 in a state where the window opening 3 is closed by the plane lattice body 5.

A method of using the surface grating 1 will be described. First, as usually shown by the solid line in FIGS. 5 and 6,
The window opening 3 is closed by the surface lattice main body 5, and the switch main body 14 receives the magnetic force of the magnet member 2b facing it and maintains the OFF state, whereby the buzzer 17 is in the inoperative state.

In this state, as shown by phantom lines in FIGS. 5 and 6, when the surface lattice main body 5 is moved to the right or left, the magnet member 2b attached to the surface lattice main body 5 is switched. Since it separates from the main body 14, the switch main body 14 is turned on and the buzzer 17 operates. Therefore, even if an outsider accidentally opens the surface lattice 1 and tries to enter the room, it can be detected reliably and an alarm can be issued.

When an emergency such as a fire occurs, the surface lattice main body 5 may be moved to the right or left to open the surface lattice 1. As a result, it is possible to escape from the window opening 3 to the outside of the room, and the operation of the buzzer 17 can notify the surroundings of the occurrence of an emergency.

Further, by pressing the alarm switch 19, the buzzer 17 can be operated without moving the plane lattice main body 5, which is useful for preventing crime in the room.

In addition, in order to take an article in or out through the window opening 3, the power switch 20 may be turned off, and then the surface lattice body 5 may be moved to open the surface lattice 1. As a result, goods and the like can be taken in and out without operating the buzzer 17. As shown in FIG. 1, since the operating portion 20a of the power switch 20 does not project to the outside from the opening 23 of the exterior case 21, the operating portion 20a is operated from the outside to turn off the power switch 20. There is no danger of being put in a state.

According to the above construction, there is an advantage that the alarm crime prevention device 2 can be attached without performing any processing such as drilling on the surface lattice 1.

[0017]

According to the alarm / crime prevention device of the present invention, in the event of an emergency such as a fire that requires an emergency escape to the outside of the room , the surface lattice main body is moved to open the surface lattice and quickly go outside. In addition to being able to escape, the buzzer alarm by the operation of the switch body of the switch mechanism can notify the surroundings of an emergency situation, and when an outsider attempts to enter the room by opening the surface lattice, Since the buzzer is activated by the switch body and issues an alarm,
It is also excellent in crime prevention. Since this alarm crime prevention device employs a so-called non-contact actuation system in which the switch body of the switch mechanism is actuated by the magnetic force from the magnet member, the contact actuation type alarm crime prevention device adopted in the conventional plane lattice. Compared to, the structure is simpler, it is easier to assemble to the fixed crosspiece and the surface lattice main body, the cost is lower, and the movement of the surface lattice main body does not deform or damage the switch main body, and it does not rust. Since there is no contact failure due to
The crime prevention effect can be exhibited over a long period of time. Furthermore, since this alarm crime prevention device is provided with a power switch in the switch mechanism, in the case where an object is taken in and out through the window opening, after turning off the power switch,
It suffices to move the surface lattice main body so as to open the surface lattice, which allows articles to be taken in and out without operating the buzzer. Also, for example, if a crime
