Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a novel lock notification device.
[0002]
[Prior art]
In recent years, a lock confirmation device has been proposed and put into practical use. This lock confirmation device can display the lock / unlock history of the lock on the key itself, and can check whether the lock is currently locked or not by looking at the key on the go.
[0003]
However, this locking / unlocking confirmation device has a function or an effect that it can be relieved only when the lock is locked, but it cannot be remotely locked when the user forgets to lock and goes out.
[0004]
On the other hand, the go-out confirmation signal lock, which has been put into practical use in recent years, determines whether the locking / unlocking operation of the lock is from the indoor side or from the outdoor side, and there is a person in the room or going out. It is used to collect data for comprehensive management of buildings by examining whether it is inside.
[0005]
However, since the outing confirmation signal lock determines that the user is in the room when the user forgets to lock and goes out, erroneous data is given to the management system.
[0006]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a novel locking notification device that eliminates the disadvantages of the locking / unlocking confirmation device and the going-out confirmation signal lock described above, and notifies the locking when going out by voice.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention supplies a door opening signal generated when the door is opened to the input terminal of the prohibition gate that constitutes the controller, and when the cylinder lock is operated from the outdoor side. a lock operation signal generated through a timer is supplied to the inhibit input terminal of the prohibition gate, so as to actuate the Sona device that demand their locking by voice by the output of the prohibition gate, Te following, going home cylinder lock Even if a door opening signal is generated during the timer's operation time due to the lock operation signal generated when the lock is unlocked, there is no output from the prohibited gate and the sounder does not operate. It is characterized in that a lock notification is made when the door is opened by operating .
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on embodiments shown in the drawings.
1 to 3, reference numeral 1 denotes the entire cylinder lock. The cylinder lock 1 includes an outer cylinder 2 and an inner cylinder 3 that is rotatably fitted inside the outer cylinder 2. Since this configuration is not different from a conventionally known cylinder lock, further detailed description is omitted. In FIG. 3, the tumbler group of the inner cylinder 3 is omitted to simplify the drawing.
[0009]
A part of the outer surface of the outer cylinder 2 is stealed to form a flat portion 2a, and the first reed switch 4 is fixed to the flat portion 2a by, for example, screws.
[0010]
On the other hand, as shown in FIG. 3, a pair of first permanent magnets 5, 5 are mounted on the outer surface of the inner cylinder 3. Of course, these first permanent magnets 5 and 5 rotate integrally with the inner cylinder 3 at the time of locking and unlocking.
[0011]
As shown in FIGS. 3 and 4, the first permanent magnets 5, 5 are inserted into and removed from the first reed switch 4 fixed to the outer cylinder 2, as shown in the center of FIG. 4. The first permanent magnets 5 and 5 are mounted in such a positional relationship that they can be driven in close proximity to the first reed switch 4 when the key insertion angle position is at the position.
[0012]
In the illustrated embodiment, the first reed switch 4 is closed when the first permanent magnet approaches the first reed switch 4.
[0013]
Note that the use of a pair of permanent magnets to drive the first reed switch 4 is not an essential component of the present invention, but merely to ensure that the reed switch is driven.
[0014]
Since the cylinder lock is configured as described above, the unlocking operation is performed by rotating the inner cylinder 3 clockwise as shown on the right side of FIG. 4, or the inner cylinder 3 as shown on the left side of FIG. When the locking operation is performed by turning the counterclockwise, the first permanent magnets 5 and 5 are separated from the first reed switch 4, and therefore the first reed switch 4 is opened.
[0015]
Therefore, the output signal of the first reed switch 4 when the first permanent magnets 5 and 5 are separated from the first reed switch 4 is taken out as a lock operation signal L and supplied to a controller 6 (see FIG. 7) described later. .
[0016]
On the other hand, as shown in FIG. 5, a second reed switch 9 is mounted on the back side of the front plate 8 of the lock box 7, and this is also provided at a portion of the door frame (not shown) facing the second reed switch 9 when the door is closed. A second permanent magnet (not shown) is attached.
[0017]
With the configuration described above, the second permanent magnet is close to the second reed switch 9 when the door is closed, and the former is separated from the latter when the door is opened. Therefore, different signals are generated when the door is closed and when the door is opened. 9 to output.
[0018]
Therefore, an output signal at the time of opening the door is taken out from the second reed switch 9 as a door opening signal D and supplied to a controller 6 (see FIG. 7) described later.
[0019]
On the other hand, as shown in FIGS. 5 and 6, a speaker 11 constituting a musical instrument described later is attached to the front plate 8 of the lock box.
[0020]
Next, the controller 6 is configured as shown in FIG. That is, in FIG. 7, reference numeral 9 indicates the second reed switch, and the door opening signal D taken out from the second reed switch 9 is supplied to the input terminal of the inhibition gate 12.
[0021]
Further, the lock operation signal L is taken out from the first reed switch 4, and this lock operation signal L is supplied to the prohibition input terminal of the prohibition gate 12 through the timer 13 having an operation time of about 10 seconds to 20 seconds, for example.
[0022]
Then, the output signal from the prohibition gate 12 is supplied to the musical instrument 14 as an operation start signal.
[0023]
This musical instrument 14 has, for example, a sound storage device using a semiconductor integrated circuit, an amplifier, and the speaker 11 described above. When receiving the operation start signal, for example, “Please lock” ”Or“ Please lock the lock ”is transmitted to the person who is going out through the speaker 11.
[0024]
Alternatively, the sounding device may be a simple chime, in short, as long as the notification of locking and the sound correspond.
[0025]
In the lock notification device according to one embodiment of the present invention configured as described above, an opening signal D is generated when a person opens the door to go out.
[0026]
Since the lock operation signal L is not generated when the door is opened from the room side, the output signal from the timer 13 is not supplied to the prohibited input terminal of the prohibited gate 12.
[0027]
At this time, since the output signal is taken out from the prohibition gate 12 and supplied to the musical instrument 14 as an operation start signal, the speaker 11 gives a voice message to the person who is about to go out, such as “Please lock”. Communicated in Therefore, the person who wants to go out must be locked.
[0028]
On the other hand, when a person who has returned from the door attempts to unlock and enter the room, first, the lock operation signal L is supplied to the timer 13, and an output signal is output from the timer 13 to the prohibition input terminal of the prohibition gate 12 for 10 to 20 seconds, for example. Supplied.
[0029]
Therefore, even if the door opening signal D is sent to the inhibition gate 12 by opening the door thereafter, there is no output signal from the inhibition gate 12 while the output signal from the timer 13 is applied to the inhibition input terminal. Of course, the musical instrument 14 does not operate.
[0030]
In addition, even if you ignore the lock notification by voice when you go out, or if you accidentally forget the lock without knowing it, you will be unlocked when you go home and enter the room. Will not appear and will not be locked.
[0031]
Also, when a person who went out without locking due to reasons such as the presence of a housekeeper in the room returned home and entered the room, he / she did not forget that it was not locked and opened the door without performing the locking / unlocking operation. In this case, since the lock operation signal L is not generated, the voice is locked.
[0032]
However, the notification of locking at the time of entering the room can be heard quite naturally because it is generally done by thumb turn from the room side when entering the room.
[0033]
【The invention's effect】
As is clear from the above description, the present invention enables the notification of locking by voice when going out, so that not only forgetting to lock is completely prevented, but also the safety of the key is improved. There are effects such as ensuring the operation of the so-called go-out confirmation signal lock.
