Of course, when installed indoors, it is desirable to arrange an LED or the like on the receiver 31 so that the intruded portion can be quickly visually recognized by the blinking of the LED. In addition, the output unit 35 transmits an intrusion signal when entering and exiting a house or opening and closing a window on a daily basis, so that the output unit 35 may be troublesome. Therefore, the output unit 35 is provided by a main switch, a remote controller, or a mobile phone. It is desirable to configure so that the necessity of the operation can be ON / OFF controlled.
[0044]
Next, the operation of the sliding doors 1 and 2 made of aluminum sash configured as described above will be described with reference to FIGS. FIGS. 8A and 8B show a state where the sliding doors 1 and 2 are closed, and FIGS. 9A and 9B show a state where the sliding door 1 is slightly opened and the metal knob 18 and the magnet 19 of the module M are attracted. 10A and 10B show a state where the sliding door 1 is further opened and the spring 11 is bent, and FIGS. 11A and 11B show a state where the sliding door 1 is further opened than the state of FIG. FIGS. 12A and 12B show a state where the sliding door 1 is opened, and FIGS. 13A and 13B show a state where the sliding door 1 is opened. FIGS. 14A and 14B show a state where the module M is attracted to the magnet 19 by being slightly closed, and FIGS. 14A and 14B show a state where the sliding door 1 is further closed than the state of FIG. B) shows a state in which the sliding door 1 is completely closed, the magnet 19 is separated from the module M, and the module M is swinging. .
[0045]
In the state shown in FIGS. 8A and 8B, the sliding doors 1 and 2 are completely closed, and the metal knob 18 of the module M is not attracted to the magnet 19, so that the module M does not swing. keeping. At this time, the reed switch 17 of the module M is excited by the action of the magnet 20 and transmits a “close signal” to the control unit 23. Is transmitted in a "closed state", for example, at regular time intervals.
[0046]
9A and 9B, when the sliding door 1 is slightly opened, the metal knob 18 of the module M and the magnet 19 are attracted. Even in this state, the reed switch 17 of the module M receives the excitation action of the magnet 20, recognizes that the sliding door 1 is not yet opened, and continues to transmit the "close signal" to the receiver 31.
[0047]
Then, as shown in FIGS. 10A and 10B, when the sliding door 1 is further opened to hold the state in which the metal knob 18 of the module M is attracted to the magnet 19, the spring 11 for standing and holding the module M is opened. Deflection gradually. At this time, since the magnetizing action on the reed switch 17 of the module M by the magnet 20 is released, the control unit 23 is set to the “open state transmission enabled” state.
[0048]
Then, as shown in FIGS. 11A and 11B, when the sliding door 1 is further opened than in the state of FIG. 10 and the module M and the magnet 19 are separated, and the module M starts swinging by the elastic force of the spring 19, Piezoelectric power generation is started in the piezoelectric power generation unit 21, and the generated power is rectified by the rectification circuit 22 and then sent to the control unit 23. The control unit 23 operates the transmission unit 24 with the supplied power. Then, a signal notifying that sliding door 1 (sliding door 2) has been opened is transmitted from transmitting circuit section 16 to receiver 31. The transmission of this signal is continued at least while the module M is swinging.
[0049]
FIGS. 12A and 12B show a state in which the sliding door 1 is opened and the swinging state of the module M is stopped, and from this state, as shown in FIGS. When slightly closed, the metal knob 18 is attracted to the magnet 19. In this state, since the reed switch 17 of the module M is separated from the magnet 20, the signal from the reed switch 17 continues to transmit the "open signal".
[0050]
When the sliding door 1 is further closed from this state to the state shown in FIGS. 14A and 14B, the spring 11 bends while the module M is held by the magnet 19. At this time, since the reed switch 17 of the module M has moved to the position where the magnet 20 is excited, the reed switch 17 is activated and transmits a “close signal” to the receiver 31.
[0051]
Thereafter, when the sliding door 1 is completely closed, as shown in FIGS. 15A and 15B, the module M is separated from the magnet 19, and the module M swings by the elastic force of the spring 11, for example, a reed switch. The power is stored as the standby power of the reed 17, or the “close signal” transmission power of the reed switch 17 is supplied.
[0052]
As described above, in this embodiment, the piezoelectric element power generation unit 21 is configured to self-generate power and to immediately supply necessary power without relying on an external power supply every time the sliding door 1 is opened and closed. Since it is built-in and has a built-in module with a self-power generation and automatic transmission function that cannot be found from the outside and that does not require external wiring work, the sliding doors 1 and 2 are attached to the window openings of the building. Very high security performance can be easily obtained with just the same simple installation work as the conventional sliding door installation work, and the need for specialized electrical wiring work like the conventional one is unnecessary, so the construction cost is greatly increased Since the ID can be cut and the ID can be set for each module M, the transmitting point can be instantaneously specified on the receiver 31 side, and the conventional centralized security system can easily be connected to the conventional security system. A possible cement, furthermore, does not require an external power source can be external power can function even when it is cut off, the running cost can also be almost unnecessary, such an effect that.
[0053]
16 and 17 show sliding doors 1 and 2 according to a second embodiment of the present invention. The sliding doors 1 and 2 according to this embodiment are plate-shaped springs 11 according to the first embodiment. Instead of the module M to be held, the module M is arranged on the horizontal portions of the window frames 3 and 4 so as to be linearly movable, and both ends of the module M are installed and held by coil springs 11A and 11A. The metal knob 18 is provided so as to protrude from the outside of the bracket 30 at the tip end of a bracket 30 extending in the direction of the vertical portion 3A of the window frame 3 so as to exhibit the same operation as the metal knob 18 of the first embodiment. Is the same as that of the first embodiment, the same reference numerals are given to the drawings as in the first embodiment, and the detailed description thereof is omitted here.
[0054]

In addition, when the sliding door 1 is open, the magnet 19 is configured to excite the reed switch 17 of the module M as shown in FIGS. Has been abolished and configured.
[0055]
Therefore, in the sliding doors 1 and 2 according to this embodiment, since there is no need to form a triangular module swing space in the corner portion as in the sliding door 1 of the first embodiment, it is commercially available. It can be applied to the sliding door of the standard specification and can prevent the manufacturing cost of the sliding door from increasing. In addition, the retrofitting can be easily performed and the number of parts can be reduced. In addition to the operation and effect obtained in the embodiment, the operation and effect that the assembling work of the sliding door 1 or 2 and the product cost can be reduced can be obtained.
[0056]
In each of the above embodiments, the case where the module M is disposed at the upper corner portion of the sliding door 1 has been described as an example. However, the present invention is not limited to this. For example, FIG. In this manner, the modules M are arranged at the upper and lower corners of the sliding door 1, and when these modules M emit the same signal, it is confirmed that the windows are opened to prevent malfunction. Alternatively, the module M may be provided on the sliding door 2 in the same manner as in the first or second embodiment or FIG. 18, and the module M may be provided on each of the sliding doors 1 and 2.
