Such a window lock is provided with, for example, a crescent-shaped locking body (so-called crescent) that rotates about a support shaft and an operating lever connected to the locking body to rotate the locking body.

If an intruder, such as a thief, wants to enter a building through a window, the window is usually opened by breaking a portion of the window glass near the window lock, inserting a hand through it, holding the control lever and rotating the lock. After you can, open the window and break into the building.

In order to prevent such an intruder from invading such a security system, a security system capable of detecting a rotational movement (lock opening) of a window lock and generating an alarm is known. For example, Japanese Patent Laid-Open No. 2003-27781 is known.

However, in this conventional technique, an alarm sounds because a window lock cannot be prevented from opening, but an intruder can enter the building through a window after opening the window lock. Therefore, there is a possibility that an intruder may enter the building and steal while the alarm is sounding, so that security is not enough.

On the other hand, it is very rare for an intruder to break a window glass and break into a building as widely as possible, and an intruder is expected to abandon the intrusion into a building unless the window lock is easily opened.

It is an object of the present invention to provide an alarm lock that can effectively prevent an intruder from entering a building through a window.

Even if an intruder breaks a part of the window glass near the window lock and inserts a hand through the operation lever, the operation lever Cannot hold the lock. Therefore, the intruder can not easily open the window lock, and can be expected to give up the intrusion into the building, effectively preventing the intruder from entering the building through the window.

In addition, when a plurality of push buttons are not pressed in a predetermined order and the cover is removed, the alarm generating means operates and an alarm sounds so that the cover can be forcibly removed and the operation lever can be prevented from being rotated. Invasion of buildings can be more effectively prevented.

And a locking function for locking the cover with the operation lever, and the control circuit does not operate the alarm generating means when the plurality of push buttons are pressed in a predetermined order, and the locking function It can also be released by the lock state.

In the embodiment, it is preferable to provide four push buttons.

In this case, one of the four pushbuttons is for input for informing operation start when the pushbuttons are pressed in the predetermined order. One of the remaining pushbuttons may be for inputting an end of operation when the pushbuttons are pressed in the predetermined order.

And according to an embodiment, the light emitting diode is designed to be visually identified from the outside of the window while the cover is covered by the operation lever, and the control circuit is configured to emit the light emitting diode to indicate that it is functioning. It consists.

According to such a configuration, an intruder who wants to break into a building is expected to recognize that the control circuit is enabled by visually checking a light emitting diode emitting light (for example, blinking) from the outside of the window and give up the intrusion into the building. Can be. Therefore, it is possible to effectively prevent the intruder from entering the building through the window.

A spring 78 for elastically supporting the other end is provided.

The flanger 70 is formed of, for example, iron, and when a predetermined voltage is applied to the coil 75, the flanger 70 is sucked inward of the frame 71 along the axial direction due to the magnetic force. The sucked flanger 70 is absorbed by the permanent magnet 76 and maintains its position even after the energization of the coil 75 is completed. When the reverse polarity voltage is applied to the coil 75 in this state, the flanger 70 recovers outward of the frame 71 along the axial direction by the magnetic force. The recovered flanger 70 maintains its position after the energization of the coil 75 is completed by the elastic force of the spring 78.

7 is a block diagram showing the electrical configuration of the alarm lock 1 of the present invention.

As shown in FIG. 7, the operation of the alarm lock 1 is controlled by a microcomputer (microcomputer) 17 included in a control circuit arranged in the casing 4 of the main body 2. The microcomputer 17 has a switch 16, a solenoid 7, a solar panel 14, a light emitting diode 12, 13, in addition to the key input section 9 including the push buttons 91 to 94. 91A-94A), the speaker 10, etc. are electrically connected.

Inside the casing 4, a power storage device such as a battery can be arranged, and the solenoid 7, the operation notification lamps 91A to 94A, and the unlocking notification lamps are provided through the power supplied from the power storage device. 12) and the speaker 10 can be operated. On the other hand, as described above, the notification lamp 13 during the function is operated (emitted) using electric power generated using light received through the solar panel 14.

8 is a flowchart showing the control contents by the microcomputer 17 when the alarm lock 1 is used.

As shown in Fig. 8, the microcomputer 17 monitors whether the operation stop 91 is pressed (S1) and whether the switch 16 is turned off from the on state (S12).

When the switch 16 is turned off in the on state (YES in S12), and the solenoid 7 at this time is in the locked state (YES in S13), the microcomputer 17 causes the main body 2 to move upward upward. It is determined that the rotation to the speaker 10 generates an alarm (S14). On the other hand, when the solenoid 7 is not locked (NO in S13) when the switch 16 is turned off, the microcomputer 17 does not generate an alarm and the operation 91 is pressed again. It is monitored whether it has been turned off (step S1) or whether the switch 16 is turned off from the on state (S12).

If the operation stop 91 is pressed (YES to S1), the microcomputer 17 monitors whether the operation end key 94 has been pressed thereafter (S2), and the operation end key 94 is pressed. At the time of advance (YES in S2), since the operation lock 91 is pressed, it is determined whether the order of the input keys 92, 93 pressed until the operation lock 94 is pressed is the correct order ( S3).

When the input operation keys 92 and 93 are pressed in the correct order (YES in S3), the microcomputer 17 then checks whether the solenoid 7 is locked (S4). When the solenoid 7 is not locked (NO in S4), the microcomputer 17 returns the solenoid 7 to the locked state (S8), and then turns off the notification lamp 13 during the extinguished function. It turns on (S9), and also turns off the unlocking notification lamp 12 which is lit (S10). On the other hand, if the solenoid 7 is locked (YES in S4), the microcomputer 17 sucks the solenoid 7 to release the lock (S5), and then turns off the notification lamp 13 in the flashing function. It is turned off (S6) and the unlocking notification lamp 12 which is turned off is turned on (S7). Next, the microcomputer 17 again monitors whether the function 91 is pressed (S1) and whether the switch 16 is turned from the on state to the off state (S12).

Even when the input operation keys 92 and 93 are not pressed in the correct order (NO in S3), they are not pressed by the predetermined number of times (for example, up to once) (NO in S11). 17 monitors whether the operation opening 91 is pressed again (S1) without generating an alarm (S1) and whether the switch 16 is turned off in the on state (S12). Through this, the user can prevent the alarm from being generated only by wrongly pressing the input operation keys 92 and 93 once. On the other hand, when the input operation keys 92 and 93 have not been pressed twice in the correct order (YES in S11), the microcomputer 17 generates an alarm in the speaker 10 (S14).

The alarm generated by the speaker 10 is, for example, 100 dB information and is continuously generated only for a predetermined time (for example, 15 seconds).

In this embodiment, the cover (peripheral portion of the recessed portion 5 in the casing 4 of the main body 2) covers the operation lever 23 so that the operation of the operation lever 23 can be made impossible. Even if a part of the window glass near the window lock 20 is broken and a hand is inserted therein, it is not possible to rotate the locking member 22 by holding the operation lever 23. Therefore, the intruder can not easily open the window lock 20 can be expected to abandon the intrusion into the building and can effectively prevent the intruder from entering the building through the window.

In addition, when a plurality of push buttons 91 to 94 are not pressed in a predetermined order and the cover is removed (when the main body 2 is rotated upward), the speaker 10 generates an alarm so that the cover is opened. Peel off excessively and can prevent the operation lever 23 to be rotated, so that the intruder can be more effectively prevented from entering the building through the window.

Furthermore, an intruder who wants to break into a building can expect to notice that the control circuit is functioning and abandon the intrusion into the building by visually confirming the notification lamp 13 in the blinking function from the outside of the window. This makes it possible to more effectively prevent intruders from entering windows through windows.

A part of the locking body 22 of the lock 20 can be inserted through.

The projection 105 in a flat state is formed at the edge opposite to the upper surface plate 103D of the rear surface 103B of the cover 103. One end surface (upper end surface) in the longitudinal direction of the main body 102 is provided with a penetrating hole 106 for inserting the projection 105 in a state where the cover 103 is closed. Inside the main body 102, for example, a solenoid 7 and a switch 16 (not shown) having the same configuration as shown and described with reference to FIGS. 5 and 6 are disposed, and the cover 103 is closed. In the state, the movable part 16A of the switch 16 is pressed against the projection 105 so that the switch 16 is turned on and at the same time, the through hole in which the flanger 70 of the solenoid 7 is formed in the projection 105. By locking in (not shown), the cover 103 is locked in the closed state.

A plurality of (for example, four) push buttons 191, 192, 193, and 194 are disposed in parallel with the short direction of the casing 104 on the front surface of the casing 104. The alarm lock 101 functions in response to the four push buttons 191 to 194 being pressed in a predetermined order, and among the functions, the four push buttons 191 to 194 are predetermined, as described above. When pressed in order, the function state is released. One of the four push buttons 191 to 194 is for inputting the meaning of the operation start when the push buttons are pressed in the predetermined order (operation operation), and one of the other push buttons presses the push button. It is for inputting the meaning of operation termination when pressed in the predetermined order (operation termination key). That is, when operating the alarm lock 101 or releasing the function state, after operating the operation button, the other two push buttons (input operation keys) are pressed in a predetermined order and finally the operation termination key is pressed. .

On the front surface of the casing 104, there is provided a light emitting diode (unlocking notification lamp 112) which lights up when the locking state (lock state) of the solenoid 7 is released (when the lock is open).

On the back side of the casing 104, a light emitting diode (notifying lamp in function) 113 for informing that the alarm lock 101 is functioning is disposed. The solar panel 114 is disposed on the side of the notification lamp 113 among the functions, and the solar panel 114 generates power using the light received by the solar panel 114. It is made to emit light.

The alarm lock 101 has its cover 103 closed below the window lock 20 with respect to the outer surface of the window frame 30 where the main body 102 is provided with the window lock 20. It is provided so that it may be located above the main body 102 in a state. In this state, the interior of the building is located in front of the alarm lock 101, and the exterior of the building is located behind the alarm lock 101 at the rear side (the rear side of the window). Therefore, the notification lamp 113 of the function disposed on the back of the casing 104 is backward and can be visually confirmed from the outside of the window through the window glass of the window frame disposed behind.

A control circuit (not shown) including a microcomputer is provided inside the main body 102 of the alarm lock 101. The microcomputer of the control circuit shown in FIG. 8 performs the same control as the control.
