DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a wireless security system using a magnetically actuated proximity sensor.

[Prior Art] This type of wireless security system is used to detect the opening and closing of sliding windows, etc., but its basic configuration is as shown in Figures 7 and 8. 100 a,
Two window frame bodies 100, 10 with 100a attached
Attach a small permanent magnet 101.101 to the opening of 0,
The window frames 102, 102, in which these two window frame bodies 100゜100 are slid and housed so as to be openable and closable, are turned on and off by detecting the change in magnetic force due to the contact and separation of the respective permanent magnets 101゜101. It has a structure in which wireless transmitters 103, 103 each having a built-in magnetically actuated sensor section are attached in correspondence with each other, and when the window frame bodies 100, 100 are properly closed, a signal is sent to both window frame bodies 100° on the 100 side. The positions of the attached permanent magnets 101, 101 are close to the wireless transmitters 103, 103, and the attached permanent magnets 101, 101 are built into the sensor section.
Turn on the switch (not shown), and turn on the window frame bodies 100, 10.
When 0 is opened or closed incorrectly,
When the position of the permanent magnet is out of the operating range of the sensor part, a reat switch (not shown) built into the sensor part is turned off to detect the open/closed state of the window, and the open/closed detection signal at this time is
The configuration is such that it is transmitted in the form of a radio wave signal to a wireless receiver located separately.

However, in conventional crime prevention systems like this,
When monitoring the opening and closing of double-paned windows, a wireless transmitter and permanent magnet must be installed as a set for each window, which increases the number of system components, disturbs the appearance, and increases cost. This was a factor.

In addition, conventional security systems like this do not only monitor the open/closed state of the window, but also monitor the locked or unlocked state of the window, but if such monitoring is required, another sensor means may be used. I needed to add it.

[Problems to be Solved by the Invention] The first object of the present invention is to provide a wireless transmitter and a permanent magnet that are applied to monitor the opening/closing status of double-paned windows. The purpose of the present invention is to provide a wireless crime prevention system that can reduce the number of required devices and reduce costs.

A second object of the present invention is to provide a wireless security system that incorporates a security sensor with a novel configuration that can detect not only the opening and closing of windows, but also the locking and unlocking of windows.

[Means for Solving the Problems] The first system of the present invention proposed to achieve the above object is a system that uses one window glass or the side of a window frame body of a two-paned window that is opened and closed by sliding vertically or horizontally. The opening and closing state of the window is controlled by the contact between a permanent magnet installed at the edge and a permanent magnet installed at the side edge of the other window frame of the two-panel window, which changes as the window frame opens and closes. A wireless transmitter that detects the ID code and transmits a security radio signal containing the ID code, and a security receiver that receives the security radio signal from the wireless transmitter and notifies the open/closed status of the window. It is characterized by having the following.

In addition, the second system of the present invention proposed at the same time is provided with a permanent magnet in the operation piece of the rotary lock pawl that locks and unlocks the window by engaging and disengaging the engaging portion provided on the window frame side. A wireless transmitter is provided in close proximity to the permanent magnet and has a built-in magnetic force-operated proximity sensor unit that detects locking and unlocking by changing the position of the operating piece of the rotary lock pawl.

[Operation] According to the wireless crime prevention system of the present invention (first invention system), the wireless transmitter is installed at the side edge of the window frame of the two-pane window, so in the conventional system, the two-pane window cannot be opened or closed. What used to require two wireless transmitters for monitoring only requires one wireless transmitter, simplifying the security system.

Further, according to the wireless crime prevention system of the present invention (second invention system), it is possible to detect not only the open/closed state of the window but also the locked/unlocked state, so that the wireless crime prevention system is even more reliable in terms of crime prevention. can get.

[Example] An example of the present invention will be described below with reference to the attached drawings.

B, and is provided with a sensor section (not shown) having a switch operated by the magnetic force of the permanent magnet A.

Therefore, each security sensor has two window frame bodies 1
00, 100'' is in the correct closed position and the permanent magnet A approaches the sensor part, the sensor part is turned on, and turned off when the window frame body 100, 100' moves out of its correct closed position. The open/closed state of the window is detected, and the wireless transmitter B detects the open/closed state of the window.
When a security signal with an ID code pre-assigned to the device is transmitted in the form of a radio wave signal, it is received by a separate security receiver, and the security receiver that receives this signal opens its window. If it determines that something is wrong, it will output an alarm or other sound to notify you.

By the way, in configuring such a system of the present invention, the width tB of the wireless transmitter B needs to be smaller than the width 1 of the side edge 100'b of the window frame body 100'. , such a request for miniaturization is I
