Description: TECHNICAL FIELD The present invention relates to an improvement in a wireless security system using a magnetically-operated proximity sensor.

[Prior Art] This kind of wireless security system is used for detecting the opening / closing of a sliding window or the like. The basic configuration thereof is, as shown in FIGS. , 100a
At the corners of the two window frame bodies 100, 100 having attached thereto, small-sized permanent magnets 101, 101 are mounted, and the two window frame bodies 100, 100 are slidably accommodated in the window frames 102, 102 side, respectively. It has a structure in which wireless transmitters 103, 103 with built-in magnetically actuated sensor units that detect magnetic force changes due to the contact and separation of the permanent magnets 101, 101 and turn on and off are installed correspondingly, and the window frame bodies 100, 100 close properly The permanent magnet 1 attached to both window frames 100, 100 when
The location of 01,101 approaches the wireless transmitters 103,103,
When the reed switch (not shown) built in the sensor unit is turned on and the window frame 100, 100 is not opened or closed properly, the position of the permanent magnet is out of the operation area of the sensor unit, and the reed switch built in the sensor unit. A switch (not shown) is turned off to detect the open / closed state of the window, and the open / closed detection signal at this time is transmitted in the form of a radio signal to the separately placed wireless receiver.

However, in such a conventional security system, when monitoring the opening / closing of two windows, it is necessary to use a wireless transmitter and a permanent magnet as one set for each window. Increase the parts,
This impaired the appearance and increased the cost.

Also, in such a conventional security system, it is only possible to monitor the open / closed state of the window, and cannot monitor the locked or unlocked state of the window.If such monitoring is required, another sensor means is required. It needed to be added.

[Problem to be Solved by the Invention] A first object of the present invention has been made in view of such circumstances, and a wireless transmitter and a permanent magnet applied to monitor the open / closed state of a two-pane window It is an object of the present invention to provide a wireless security system that can reduce the required number of devices and the cost.

It is a further object of the present invention to provide a wireless crime prevention system capable of commercializing a wireless transmitter smaller than the width of a window frame.

[Means for Solving the Problems] A first system of the present invention proposed to achieve the above object is a wireless system formed to have a size smaller than the width of the side edge of one of the two window frames. A transmitter is attached to a side edge of one of the two window frames, and a permanent magnet is attached to a corresponding side edge or window glass of the other window frame of the two windows, The security receiver receives and detects the radio signal obtained by adding the open / close signal to the ID code transmitted from the wireless transmitter, and notifies the open / closed state of the two windows. An IC chip with a control circuit mounted inside the package from which the connection pins are derived is built in, and the ID code is fixed by selectively bonding the conductive connection of the IC chip to the connection pins. Configuration set to Going on.

Also, the second proposed system of the present invention is
The pivotable locking claw attached to the side edge of one window frame of the single window or the window frame of the vertical opening / closing window is engaged with the engaging portion attached to the other window frame or the window frame of the vertical opening / closing window. In the wireless security system for locking and unlocking the lock, a permanent magnet is attached to the operation piece of the rotary lock claw, and a side edge portion of one window frame body to which the rotary lock claw is mounted. Alternatively, a magnetically actuated proximity sensor is built into the window frame of the upper / lower opening window, and the wireless frame has a dimension smaller than the width of the side edge of the one window frame or the width of the window frame of the upper / lower window. A transmitter is installed, and a proximity sensor built into the wireless transmitter is brought close to a permanent magnet attached to the operation piece of the rotary lock claw, and the locking position of the rotary lock claw and the unlocking position are released. Turn on and off according to the lock state. Locked position to the ID code sent from the scan transmitter receives to detect a radio wave signal added the unlocking signal in the security receiver, the window is in the locked position,
Notifying that the wireless transmitter is in the unlocked position, the wireless transmitter incorporates an IC chip in which a control circuit unit is mounted in a package from which a plurality of connection pins are derived.
The ID code is fixedly set by selectively bonding the conductive connection portion of the IC chip to the connection pin.

[Operation] According to the wireless crime prevention system (first invention system) of the present invention, the wireless transmitter is installed on the side edge of the window frame having two windows. What required two wireless transmitters for monitoring may be replaced by one wireless transmitter, which can simplify the security system.

Further, since the ID code of the wireless transmitter can be fixedly set by automatic bonding inside the package of the IC chip, the size can be further reduced, and the ID code can be set at the manufacturing stage, which is suitable for mass production.

Further, according to the wireless crime prevention system (second invention system) of the present invention, it is possible to detect that the window is in the locked position and that the window is in the unlocked state.

Further, since the ID code of the wireless transmitter can be fixedly set by automatic bonding inside the package of the IC chip, the size can be further reduced, and the ID code can be set at the manufacturing stage, which is suitable for mass production.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an example in which the present invention is applied to a left-right sliding two-window, and FIG. 2 shows an example in which the present invention is applied to a vertically sliding two-window.

As shown in these figures, in these systems, the security sensor uses a permanent magnet A on the corner of the glass surface 100a of one window frame 100 or the side edge 100b of the window frame 100 using an adhesive or the like. , A, and the side edge surface 10 of the other window frame 100 ', 100'.

Is formed to have a width tB smaller than the width t of the side edge portion 100 ′ b, and a sensor unit (not shown) having a reed switch operated by the magnetic force of the permanent magnet A is provided.

Therefore, each security sensor has two window frames
When the permanent magnet A comes close to the sensor section when the 100, 100 'comes to the correct closing position, the sensor section turns on, and when the window frame 100, 100' moves out of the correct closing position, the sensor section turns off and the window opens and closes. When the state is detected and the security signal to which the ID code previously assigned to the wireless transmitter B is transmitted in the form of a radio signal from the wireless transmitter B, the security signal is received by the separately provided security receiver, When the security receiver receives this signal and determines that the window is open, the security receiver outputs an alarm sound or the like to notify the user.

By the way, in the case of configuring such a system of the present invention, the width dimension tB of the wireless transmitter B is different from the window frame body.
Although it is necessary to form the side edge portion 100'b of the 100 'smaller than the width dimension t, such a demand for miniaturization can be realized by reducing the circuit space required for setting the ID code. .
