Abstract

PROBLEM TO BE SOLVED: To improve the prevention of crimes by fixing a lock to be fastened and unfastened at its close position on an openable glass door, and then fitting an impact sensor to sense impacts in the lock. SOLUTION: A fastened and unfastened lock state of a crescent lock 10 is sensed by a fastened and unfastened lock sensor fitted in the casing 44 of a pedestal 16 to subsequently be transmitted to a host system via a controller and RF module 48, then the host system indicates it to a fastened and unfastened lock state indicator. Following this, when the indicator is verified and a set switch of the host system is turned on at the time of going to bed, the sensor 39 and Impact sensor 40 are on alert. After that, if an unlawful intruder tries to break glass around the lock 10 and to make a hole for unfastening the lock 10, then the sensor 40 senses the impacts so that alarms of the host system and subsystem operate. Furthermore, the sensor 40 formed by a piezoelectric film is disposed in parallel with the glass surface so as to sense impacts sensitively and positively. Consequently, the prevention of crimes can be extremely enhanced, and the system can be miniaturized.

Etc. are connected.

The set / reset switch 58 is a manual switch that puts the master unit 43 in a set state or releases the set state (including stopping the alarms 50 and 56) when going out or going to bed. Control unit 5 of the parent device 43
3 is set / reset switch 58 only when all the locked / unlocked state display sections 55 display the locked / unlocked state.
It is set to enter the set state (alert state) by turning on.

Also, in this set state, the signal that the impact sensor 40 senses an impact or the locking / unlocking sensor 3
It is set so that the alarms 50 and 56 of the slave unit 42 and the master unit 43 are activated (alarm is issued) in response to the signal that 9 has detected the unlocked state. It is preferable that the control unit 53 of the parent device 43 is provided with sensitivity adjusting means for adjusting the sensitivity so that the shock sensor 40 does not pick up unnecessary vibrations other than the shock of breaking the glass 7.

Next, the operation of the sash constructed as described above will be described. Normally, the crescent lock 10 is locked after the inner shoji 3 and the outer shoji 4 are closed.
There is a case where the locking operation is erroneously performed in a state where the inner shoji 3 and the outer shoji 4 are insufficiently closed or the inner shoji 3 and the outer shoji 4 are opened. In such a case, when the handle 8 of the crescent lock 10 is rotated in the locking direction from the unlocked position a as shown in FIGS. 5A and 5B, the contact surface portion 29 of the rocking body 23 receives the crescent lock. 11 receiving part 13
Since it does not come into contact with, the claw portion 28 of the rocking body 23 is locked to the locking portion 24 on the pedestal 16 side, and the rotation of the handle 8 is blocked. Therefore, since the handle 8 cannot be further rotated in the locking direction, erroneous locking can be prevented.

When the handle 8 is released, the handle 8 is automatically returned to the release position B by the spring 34.
The hanging portion 9 of the crescent lock 10 does not remain extended in the locking direction. Therefore, even if the inner sliding door 3 and the outer sliding door 4 are opened and closed thereafter, the hanging portion 9 and the vertical frame 6d of the outer sliding door 4 do not collide and are not deformed or damaged, and the durability can be improved. .

On the other hand, when the inner door 3 and the outer door 4 are in the normally closed position, as shown in FIGS. 6A and 6B, the handle 8 of the crescent lock 10 is locked from the unlock position a. When the handle 8 is rotated, the contact surface 29 of the hanging portion 9 and the rocking body 23 approaches the crescent receiver 11 as the handle 8 rotates, and further, as shown in FIG. 29 abuts on the receiving portion 13 of the crescent receiver 11 and falls against the urging force of the return spring 30 about the support shaft 25 as a fulcrum, and the claw portion 28 of the oscillating body 23 is engaged by the reaction force or reaction. It separates from the stop 24.

Therefore, the claw portion 28 of the rocking body 23 is not locked to the locking portion 24, that is, the rotation preventing mechanism 14 is released, and the handle is turned as shown in FIG. 6 (d). It is possible to rotate 8 as it is to the locking position (b), and it is possible to securely lock the hook 9 by fully engaging the hanging portion 9 with the receiving portion 13 of the crescent receiver 11. In addition, the claw portion 28 separated from the locking portion 24 is the guide portion 31 as it is.
By being guided along, the contact surface portion 29 of the rocking body 23 is maintained in a tilted state.

When the crescent lock 10 is unlocked, the handle 8 may be rotated in the unlocking direction from the locking position B, and the hooking portion 9 and the abutting surface portion of the rocking body 23 in the reverse order to the above. 29 is separated from the crescent receiver 11, and the abutting surface portion 29 of the rocking body 23 is not caught by the receiving portion 13 of the crescent receiver 11 and can be unlocked reliably and easily.

As described above, the crescent lock 10 can mechanically detect whether the inner sliding door 3 and the outer sliding door 4 are in the normally closed position by utilizing the rotation of the handle 8, and thus the normally closed position can be obtained. The handle 8 can be pivoted sufficiently in the locking direction only when it is in the position to securely lock the handle. The locked / unlocked state of the crescent lock 10 is detected by the locking / unlocking sensor 39 provided in the casing 44 of the pedestal 16. If the locking / unlocking sensor 39 detects the locked / unlocked state, the shoji 3 and 4 are always normal. In the closed position, it is securely locked by the crescent lock 10.

The locked / unlocked state of the crescent lock 10 is detected by the locking / unlocking sensor 39, and the control unit 47 and RF.
A radio signal is transmitted to the parent device 43 via the module 48, and the parent device 43 receives the signal via the RF module 52 and the control unit 53 and displays it on the locking / unlocking state display unit 55. When setting the master unit 43 to the set state when going out or going to bed, etc., confirm that all the lock / unlock state display sections 55 display the locked state by the signals from all the slave units 42, and set. The reset switch 58 may be turned on.

When the set state is set, the set state is transmitted from the master unit 43 to the slave unit 42, whereby the light emitting element 51 of the slave unit 42 blinks and it is confirmed that the set state is set. . In addition, when the above-mentioned set state is set, the alert state is set via the impact sensor 40 and the locking / unlocking sensor 39 of each child device 42. Therefore, when an unauthorized person attempts to unlock the sash's crescent lock 10 in the locked state, he or she first attempts to break the glass 7 of the shoji 3 or 4 near the crescent lock 10 to open a hole. The shock generated at this time is detected by the shock sensor 40.

The alarm 50 of the slave unit 42 is activated by the signal that the impact sensor 40 senses the impact, and the alarm 56 of the master unit 43 is activated by receiving the signal from the slave unit 42. In addition, the external reporting means 57 from the parent device 43
It is also reported to the outside via the. By the operation of the alarm 50 of the child device 42, a person who attempts an illegal intrusion can be frightened and the illegal intrusion act can be stopped.

Even if an attempt is made to continue an illegal intrusion, it is a stage before unlocking the crescent lock 10.
Since there is time until the intrusion into the room from now on, it is possible to sufficiently deal with the illegal intrusion act. In order to stop the operation of the alarms 50 and 56 and to release the set state, the set / reset switch 58 may be turned off.

As described above, according to the sash, the glass door screens 3 and 4 provided in the opening of the building so as to be openable and closable via the frame 2 are provided with the crescent lock 10 as a lock for locking and unlocking the glass door screens in the closed position. Since the impact sensor 40 for detecting an impact is provided integrally with the crescent lock 10, the impact sensor 40 can reliably detect the impact generated when the glass 7 near the crescent lock 10 is broken. , An illegal intrusion act can be detected at a stage before the crescent lock 10 is illegally unlocked, and the crime prevention can be further improved.

Further, since the pedestal 16 of the crescent lock 10 is provided with the locking / unlocking sensor 39 for detecting the locked / unlocked state via the detected body 41 provided in the handle 8, the impact sensor 40 is provided, and thus the locked / unlocked state is provided. It is possible to adopt a configuration in which the shock sensor 40 enters the alert state after confirming the above, and at the same time, it is possible to provide the locking / unlocking sensor 39 and the shock sensor 40 as a unit on the pedestal 16, thus making it compact. Can be achieved.

In particular, the crescent tablets 10 are
Since the handle 8 itself is provided with a mechanism capable of mechanically detecting whether or not 4 is in the normally closed position and locking only when in the normally closed position, such a mechanism is disclosed in, for example, Japanese Patent Laid-Open No. Unlike the case of electrical, optical or magnetic construction as described in Japanese Patent Publication No. 2-274982, it is not necessary to make any work on the crescent receiver 11 side, and the locking / unlocking sensor 39 and the impact sensor 40 are not required. The included electric part can be separated from the mechanism and put together in one place, and the unitization and the compactification can be easily achieved.

Further, since the impact sensor 40 is composed of a piezoelectric film sensor and the piezoelectric film sensor is arranged in parallel with the glass 7 surface of the glass door screens 3 and 4, the impact generated when the glass 7 is broken. Sensitively,
It becomes possible to detect more reliably.

Although the embodiments of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the above embodiments, and various design changes and the like without departing from the gist of the present invention. Is possible. For example, although the case where the present invention is applied to the sliding type sash is shown in the above embodiment, the present invention is not limited to the sliding type sash. It can also be applied to various sashes that it has. Further, the lock is not limited to the crescent lock, but may be a cam latch or the like.

The impact sensor and the like may be provided separately from the crescent lock including the pedestal. The impact sensor is preferably a piezoelectric film sensor, but may be an acceleration sensor other than the piezoelectric film sensor. A reed switch is preferable as the locking / unlocking sensor, but a micro switch or the like may be used. Further, in the above-described embodiment, the crescent lock having a mechanism for mechanically sensing the normal locking position of the shoji screen is shown, but the crescent lock or the lock does not necessarily have to have such a mechanism.
