Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a device for preventing forgetting to lock a door lock or the like.

[Conventional technology]

Conventionally, as in the invention described in Japanese Examined Patent Publication No. 57-32396, detecting the locking / unlocking state of locks Ki to Kn in the passenger compartment and the opening / closing state of gas opening / closing devices, etc., a master lock Kn provided at the entrance etc. However, it requires a discriminating unit 5, a setting unit 6, a comparing unit 7, a control unit 9, and the like as its constituent elements, resulting in a large-scale device.

Also, as described in Japanese Patent Publication No. 56-48482, there is one in which the power of the room is controlled by the presence or absence of a key in the key storage, but in the present invention, the key is removed from the storage when going out. Although I took it out, I could not prevent it from going out without forgetting to lock it.

[Problems to be solved by the device]

In order to solve the above-mentioned conventional drawbacks, the present invention has an extremely simple structure and can reliably prevent forgetting to lock the lock when going out or going home.

[Means for Solving the Problems] In order to achieve the above object, the device of the present invention is an unlocking device for a door lock.
A switch that turns on is provided, and a key storage for storing the key for the door lock is provided inside the room, and a switch that turns off and on when the key is stored or taken out is provided in the key storage. And a buzzer are connected.

Further, the key storage may be a card storage of a card lock which has been frequently used recently.

Further, the buzzer may be audible both outdoors and indoors with one buzzer, or may be provided both outdoors and indoors.

The switch provided on the door lock is turned on in the unlocked state, and the switch in the key storage is turned on when the key is taken out, and those switches are connected in series with the buzzer.

Then, when you go out and take out the key from the key storage installed inside the room (with the door lock unlocked), the switch turns on and the buzzer sounds and the buzzer sounds to let you know that it is not locked. . If you lock it with the key, the switch on the door lock will turn off and the buzzer will stop sounding. Therefore, it is possible to prevent forgetting to lock when going out.

When returning home, the switch on the door lock turns on when unlocked
A buzzer sounds next to inform you of the unlocked state. The buzzer stops when locked from the inside.

〔Example〕

 Examples will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 is a door lock attached to the door D, and a switch 1 _s is built in the case, which is turned on when the door lock 1 is unlocked and turned off when the door lock is locked.
It is provided so that

In addition, 3 is a key storage attached to the wall on the indoor side,
There is a switch 3 _{s that} turns on when the key 4 is taken out and turns off when it is stored.

The switches 1 _s and 3 _s are connected via a wire fitting 2. A buzzer 5 is connected in series with the switches 1 _s and 3 _s . E is a power supply.

FIG. 1 shows a state in which the door lock 1 is locked and the key 4 is stored in the key storage 3. In this state, as shown in FIG. 2, the switch 3 _s provided in the key storage 3 is ON, but the switch 1 _s provided in the door lock 1 is OFF, so that the buzzer 5 has No current flows and the buzzer 5 does not ring.

Then, when going out, when the key 4 is taken out from the key storage 3, the switch 3 _s is turned on. Next, when unlocking the door lock 1,
Since the switch 1 _{s is} also turned on, the buzzer 5 sounds to inform the unlocked state. When the door lock 1 is locked from the outdoor side, the switch
Since 1 _s is turned off, the power to the buzzer 5 is cut off and the buzzer 5 stops ringing. Therefore, forgetting to lock does not occur.

Further, when returning home, if the door lock 1 is unlocked first, the buzzer 5 starts to ring as described above. If the door lock 1 is locked from the indoor side, the buzzer 5 stops ringing. That is, it is possible to prevent forgetting to lock.

It should be noted that, when the key is unlocked at the time of returning home and the buzzer sounds, the buzzer 5 stops ringing even if the key 4 is stored in the key storage 3 without locking.

At bedtime, when the door lock 1 is locked and the key 4 is taken out from the key storage 3, if it is unlocked illegally, the buzzer 5 sounds and it also functions as an alarm device. .

In the present invention, the door lock 1 is not limited to the type in which the key is locked and unlocked from the outdoor side as described above, and may be a card lock that is locked and unlocked by a card, for example. In that case, the key storage 3 may be provided so that the switch 3 _s is turned OFF and ON when the card is stored or taken out.

Further, the types of the switches 1 _s and 3 _s , the mounting method, and the like are not limited at all.

Further, the form of the key storage 3 is not limited at all, and may be a box type or a hanging type, and may be arbitrary.

The buzzer 5 is not limited to the buzzer,
A lamp or the like may be provided so as to blink, and the blinking of the lamp may notify that the user has forgotten to lock.

Besides, the circuit is not limited to the one shown in FIG.
It may be linked with various other electric devices and is arbitrary.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

First of all, when going out, when the key is taken out from the key storage, the buzzer sounds unless locked, so that the unlocked state can be immediately discriminated, and it is possible to reliably prevent going out without forgetting to lock.

Further, even when returning home, if the door lock is in the unlocked state without storing the key, the buzzer sounds to inform the unlocked state, and forgetting to lock can be prevented. In addition, when the family frequently goes in and out during the daytime, even if the door lock is unlocked, if the key is stored in the key storage, the buzzer will stop sounding, so the key will be stored in the specified place (key storage). It is possible to prevent forgetting to store.

Furthermore, it is convenient to confirm that the key is unlocked by removing the key from the key storage before going to bed, and it is illegal to remove the key before going to bed. The buzzer sounds when unlocked, so it also functions as an alarm device.

Moreover, since the structure is extremely simple, the entire device can be provided in a small size and at low cost.
