DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a door switch used at or near a door of a house, and more particularly to a door switch having a keyboard for inputting a code number.

[Prior Art] Recently, electronic lock systems have been provided that include a door switch provided with a keyboard for inputting a password at or near the door of a house. In addition to the door switch, this electronic lock system also includes:
A control device including a setting means for setting and registering a PIN number and a comparison means for comparing the number entered on the keyboard with the set and registered number, and an electronic lock that is unlocked by an electronic lock unlocking signal from the control device. This is a system whose main component is a lock. In this electronic lock system, when the number entered on the keyboard matches the pre-stored number, the control device outputs an electronic unlock signal to the electronic lock, which unlocks the electronic door lock. .

By the way, the above-mentioned door switch has a structure in which the keyboard is exposed to the outside, or it has a structure in which the keyboard is simply covered with a cover exclusively for the keyboard.

[Problems to be Solved by the Invention] As described above, the door switch in which the keyboard is exposed to the outside has a problem in that the keyboard is easily manipulated by mischief. Furthermore, even with a door switch that covers the keyboard with a dedicated cover for the keyboard, it is easy to tamper with the switch since it is possible to guess that there is a keyboard inside the cover. The present invention has been made to solve the above-mentioned problems.

[Means for Solving the Problems] As a result of extensive research, the inventor of the present invention has found that the above problems can be solved by hiding the keyboard inside the door or a cover that includes a doorbell operating member provided near the door. It was made by

The door switch of the present invention is composed of a base fixed to the door or near the door, a keyboard held on the base for inputting a number, and a cover that opens and closes the keyboard and includes a doorbell operating member. It is characterized by the fact that

The base, which is a component of the present invention, is a member that has the function of holding the keyboard, and is fixed to the door or the vicinity of the door. A typical base is a plate that closes the opening of a box such as a switch box buried in the wall of a house or the like. Moreover, it is not limited to a switch box, but may also be a board for holding a keyboard, a cover, etc.

The keyboard, which is a component of the present invention, is used to input a predetermined password, and usually has a numeric keypad ranging from "0" to "9". In addition to the numeric keypad, it is preferable to have a clear key for canceling input. For simplicity, some numbers may be omitted, or special symbols may be added. Such a keyboard may be one used in conventional electronic locks or computers, and may be used as is or with some modifications.

The cover, which is a component of the present invention, is a member that covers the keyboard, and is provided at the base so that it can be opened and closed. When the cover is opened, the keyboard is exposed to the outside and can be seen from the outside, and when the cover is closed, the keyboard is covered by the cover, so that the keyboard can be hidden. Generally, the configuration that allows the cover to be opened and closed is as follows:
One end of the cover is swingably supported on the base, and the other end of the cover is swingable. In some cases, the cover may be removable and may be opened by removing the cover from the base.

The cover includes a doorbell operating member. The doorbell operating member serves as a pressing portion of a switch unit for the doorbell. This switch unit can have the same structure as the conventional one. Here, it is also possible to incorporate the entire doorbell switch unit into the surface of the cover. It is also possible to provide a part of the doorbell switch unit on the base or the keyboard, and provide only the pressing part on the cover. In this case, the pressing part constituting the doorbell operating member on the cover can be pressed by a person with a finger or the like. For example, a doorbell switch unit provided on the base or keyboard is input.
Here, the doorbell switch unit means a switch unit that energizes the electric circuit that activates the doorbell. Therefore, when the switch unit is turned on, the doorbell will ring. Therefore, it is possible to notify people of their arrival.

It is also preferable that the cover or base is provided with a microphone and a speaker functioning as an intercom. The microphone and speaker can have the same structure as a conventional intercom. When unlocking the electronic lock from the outside of the door, the electronic lock is unlocked when two conditions are met: the password entered from the keyboard is correct and the cover is closed. It is preferable that In this way, it is possible to prevent forgetting to close the cover when unlocking.

[Function] A typical method of using the door switch of the present invention will be described. Normally, the cover containing the doorbell operating member is closed and the keyboard is covered with the cover. In this way, you can hide the location of your keyboard from others. On the other hand, when a visitor comes, the visitor operates the doorbell operating member on the cover. At this time,
The keyboard is hidden by the cover, so
It is possible to prevent visitors from knowing the location of the keyboard. Furthermore, when opening a door that is locked with an electronic lock from the outside, the cover is opened from the outside of the door to expose the keyboard in order to input a password on the keyboard.

This electronic lock 9 is well known, and is configured such that when energized, a built-in motor rotates, and the lock is unlocked by converting this rotational movement into linear movement using a combination of a pinion and a rack. As the power supply section 300, a transformer for a distribution board (model WR2201 manufactured by Matsushita Electric Works Co., Ltd.) was used.

FIG. 25 is a block diagram for explaining the system of this example. Here, an outline of this block diagram will be described. Signals from the keyboard 20 and signals from the cover opening/closing detection device 35 are input to the control device 100, respectively. And firstly,
The password set and registered in the control device 100 and the number entered on the keyboard 20 must match, and secondly, after operating the keyboard 20, the cover opening/closing detection device 35 receives a cover closing signal. is input into the control device 100, when the two conditions are met, the control device 100
outputs an electronic lock locking signal to the electronic lock 9.

On the other hand, when the number entered on the keyboard 20 and the number registered in the control device 100 do not match, the control device 100 outputs an alarm buzzer signal to the alarm buzzer 62,
2 becomes.

Now, the case of unlocking the electronic lock 9 from the outside of the door will be described with reference to the block diagram of FIG. 25 and the flowchart of FIG. 26. That is, first cover 30
to open. Then, in step 200 of the flowchart of FIG. 26, the open/close signal of the cover 30 is read, and in step 201 it is determined whether the cover is open. When the cover 30 is open, a cover open signal is input from the cover open/closed detection device 35 to the control device 100 . Next, the user presses the numeric keypad 22 of the keyboard 20 in order according to the four-digit password. Then, the key-input four-digit password data is input to the comparison circuit of the control device 100.
In steps 202 to 206 of the flow in FIG.
It is determined whether the read PIN number is correct or not. The comparison circuit of the control device 100 compares the stored password and the key-input number to detect whether they match or do not match. If there is a mismatch, an alarm buzzer signal is output to the alarm buzzer 62 in step 207 of the flowchart of FIG. 26, and the alarm buzzer 62 is activated to notify that the key has been pressed incorrectly. Here, the timer of the alarm buzzer 62 can be set to about 3 seconds. Now, after inputting the correct password into the keyboard 20, the cover 30 is closed. Then, in step 208 of the flowchart of FIG. 26, the cover open/close signal is read, and in step 207, it is determined whether the cover is open or closed.
If the cover is closed, a cover closing signal is input to the control device 100. When the cover closing signal is input to the control device 100, a timer is activated in step 210, and an electronic lock unlocking signal is output in step 211, whereby the electronic lock 9 is unlocked. Here, the above-mentioned timer keeps the electronic lock 9 in the unlocked state for 5 seconds. Therefore, after 5 seconds have elapsed, the electronic lock locking signal is sent to the control device 1 in step 212 of the flow shown in FIG.
00 is output to the electronic lock 9, and the electronic lock 9 is thereby locked. Therefore, in this example, even if a person opens the door 8, enters the house, and closes the door, the electronic lock 9 will be automatically locked after the aforementioned 5 seconds have elapsed.

As mentioned above, the electronic lock 9 is unlocked only when two conditions are met: the stored number matches the keyed-in number, and the cover 30 is closed. With this configuration, forgetting to close the cover 30 can be reliably prevented. Therefore, there is an advantage that it is possible to prevent the user from forgetting to close the cover 30 when unlocking the electronic lock 9 and entering the house, thereby preventing others from knowing the position of the keyboard 20.

Note that FIGS. 12 to 14 are process diagrams for unlocking the door 8 from the outside.

Next, regarding the case of locking the door 8 from the outside,
This will be described with reference to the flow shown in FIG. 27 and the block diagram shown in FIG. First, open the cover 30.
Then, in step 301 of the flowchart of FIG.
It is determined whether the cover is opened or not. When the cover is opened, a cover opening signal is input to the control device 100. Next, close the cover 30 and close the keyboard 20.
hide Then, in step 303, a reading of whether the cover is open or closed is performed, and in step 304, it is determined whether the cover is closed. If the cover is closed, the cover opening/closing detection device 35 outputs a cover closing signal to the control device 100. As a result, the control device 100 outputs an electronic lock locking signal to the electronic lock 9 in step 305 of the flowchart of FIG. 27, and the electronic lock 9 is thereby locked. In this way, if the electronic lock 9 is configured to be locked when the cover 30 is closed, forgetting to close the cover 30 can be prevented. Note that FIGS. 15 and 16 are process diagrams for locking the door 8 from the outside.

Next, the case of locking the door 8 from the inside, that is, the indoor side, will be described with reference to the block diagrams of FIGS. 17 to 19 and 25. That is, first, the user looks at the lock lamp 58 and confirms whether the electronic lock 9 is locked. When the electronic lock 9 is locked, a lock lamp lighting signal is output from the control device 100 to the control unit 5, so that the lock lamp 58 is turned on. Further, when the electronic lock 9 is unlocked, the lock lamp 58 is off. And if it is not locked, the control unit 5
Press the lock button 59. Then, a signal is output from the control unit 5 to the control device 100, and an electronic lock locking signal is output from the control device 100 to the electronic lock 9, so that the electronic lock 9 is locked. 17 and 18 are schematic perspective views showing the process of locking the door 8 from the inside.

Next, a case will be described in which the electronic lock 9 is unlocked from the inside of the door 8, that is, from the indoor side. Similarly to the above, check the lock lamp 58 to see if the electronic lock 9 is locked.

If the electronic lock 9 is locked, the lock button 59 is pressed. Then, a signal is output from the control unit 5 to the control device 100, and an electronic lock unlocking signal is output from the control device 100 to the electronic lock 9, whereby the electronic lock 9 is unlocked. At this time, the lock lamp 58 goes out.

Also, an incorrect input on the keyboard 20 causes the alarm buzzer 62.
When the alarm is ringing, press the alarm buzzer button 61.
Then, the alarm buzzer lamp 60 goes out, and furthermore, a signal is output from the control unit 5 to the control device 100, and the signal from the control device 100 causes the alarm buzzer 62 to stop. Warning buzzer button 6 again
Press 1. Then, the alarm buzzer lamp 60 lights up and the alarm buzzer 62 is newly set. In the set state, if an incorrect input is made on the keyboard 20 again, the alarm buzzer 62 will go off.

Next, the case of changing the password of the keyboard 20 will be described. First, as shown in FIGS. 22 to 24, insert the tip of a screwdriver into the hole 63a of the PIN cover 63 and remove the PIN cover 63. Then, insert the tip of a screwdriver etc. into the PIN number dial 64 to confirm that the incorrect PIN number dial 64
Turn to change the PIN to the specified number.
After making the changes in this manner, the password cover 63 is closed. Note that the password dial 64 can be configured with a variable resistor.
