Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Use] 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. This electronic lock system includes, in addition to the door switch, a control device including a setting means for setting and registering a code number and a comparison means for comparing the number inputted on the keyboard with the set and registered number; This is a system whose main component is an electronic lock that is unlocked by an electronic unlock signal from the device. 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 a structure in which the keyboard is simply covered with a cover exclusively for the keyboard.

[Problem 1 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 if the door switch has a keyboard covered with a dedicated cover for the keyboard, it can be assumed that there is a keyboard inside the cover, so there is a problem in that it is also susceptible to tampering. The present invention has been made to solve the above-mentioned problems.

[Means for Solving the Problems] As a result of intensive research, the inventor of the present invention has noticed that the above problems can be solved by hiding the keyboard inside a cover that includes a doorbell operating member provided at or 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 includes 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 for inputting a predetermined password, and usually has a numeric keypad ranging from rOJ 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 can be the one used in conventional electronic locks, the one used in total WIN, etc., and can 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 and can therefore be hidden. Generally, in a structure that allows the cover to be opened and closed, one end of the cover is swingably supported on a 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 portion of the cover. In addition, a part of the doorbell switch unit is provided on the base or the keyboard,
It is also possible to provide only a pressing portion on the cover, and in this case, when a person presses the doorbell operating member of the cover with a finger or the like, the doorbell switch unit provided on the base or keyboard is configured to be input. Here, the doorbell switch unit means a switch unit that energizes an electric circuit that operates a doorbell. Therefore, when the switch section of the switch unit is turned on, the doorbell rings. Therefore, it is possible to notify the arrival of a person.

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 the keyboard from the hermit. On the other hand, when a visitor comes, the visitor operates the doorbell operating member on the cover. At this time, since the keyboard is hidden by the cover, it is possible to prevent the visitor from knowing the location of the keyboard. In addition, when opening a door 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 the code number on the keyboard.

[Effects of the Invention] Since the door switch of the present invention has a structure in which the keyboard is covered with a cover including the doorbell operating member, it is possible to prevent the keyboard from being manipulated by mischief, unlike in the past. Furthermore, since the doorbell operating member is incorporated into the cover, the entire device becomes compact.

The cover 30 has a collar portion 31 at the upper end, and the keyboard 2
It is sized to cover the entire 0 numeric keypad 22. A cover 30 is attached to the plate 10. The cover 30 is configured to be able to swing in six directions of arrows and in the opposite direction about a support shaft 33 provided on a flange portion 31 of the cover 30. Therefore, the cover 30 has a structure that can be opened and closed as shown in FIGS. 2 and 3. Here, the opening and closing of the cover 30 is determined by the cover opening/closing detection device 35 (see Fig. 25).
It is now detected by. As the cover opening/closing detection device 35 for detecting opening and closing of the cover 30, for example, a press switch may be provided so that the press switch is pressed when the cover is closed.

The cover 30 is provided with a spring, and the cover 3
When the cover 30 is opened, the cover 30 does not close under its own weight due to the elastic force of the spring.

When the cover 30 is swung open, the keyboard 2
0 is exposed to the outside, so the keyboard 20 is in an operable state. Moreover, if the cover 30 is closed by swinging in the opposite direction, the keyboard 30 is hidden by the cover 30.

As is clear from FIG. 6, when the doorbell operating member 30a of the cover 30 is pressed, the doorbell operating member 30a is pressed.
The doorbell button 24a is pressed by the button a, which turns on the doorbell switch 24b, and the doorbell in the room rings.

(Control part 5) Figures 9 to 11 show the control part 5 installed on the indoor side.
The structure of Here, FIG. 9 shows a state in which the password cover 63 is closed. FIG. 10 shows the state in which the password cover 63 is opened. FIG. 11 shows the disassembled state. As shown in FIG. 11, the control unit 5 includes two switch boxes 50 embedded in the wall on the indoor side and screws 5.
The control circuit section 53 is attached to the switch box 50 by passing screws 54 through the holes 52 and 50a, and the commercially available two-piece plate 56 is attached to the control circuit section 53 by passing screws 54 through the holes 55. It has the same dimensions as the full-color plate manufactured by Matsushita Electric Works Co., Ltd.). Here, the control circuit unit 53 includes a battery check lamp 57 that informs whether or not a battery is being charged for backup in the event of a power outage, and an electronic lock button 59 that has a lock lamp 58 that lights up when the electronic lock 9 is locked. , an alarm buzzer button 61 having an alarm buzzer lamp 60, and an alarm buzzer 62
, four password dials 64 made up of small rotary switches, and a password cover 63 that is detachable and covers the dials 64 when attached to prevent the dial numbers from being seen from the outside. Here, the battery check lamp 57 lights up when power is being supplied to the control section 5, and when it becomes necessary to replace the battery for power outage, it repeatedly flashes to notify the time. . The locking lamp 58 is turned on when the electronic lock 9 is locked, and turns off when the electronic lock 9 is unlocked.

The alarm buzzer lamp 60 is turned on when the alarm buzzer button 61 is set, and is turned off when the alarm buzzer button 61 is reset.

Therefore, if the alarm buzzer button 61 is set to the reset state, the alarm buzzer 62 will not sound even if the password is pressed incorrectly. Furthermore, when the alarm buzzer button 61 is set, the alarm buzzer 62 is configured to sound if the password is pressed incorrectly.

(Electronic lock 9) As the electronic lock 9 of this example, a motor-type electronic lock (Electronic lock model EK38 manufactured by Matsushita Electric Works, Ltd.) was used. 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 unit 10, 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 2o and signals from the cover opening/closing detection device 35 are input to the control device 100, respectively. Firstly, the password 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 open/occlusion detection device When the two conditions that the cover closing signal is input from 35 to the control device 1100 are satisfied, the control device 100 outputs an electronic lock locking signal to the electronic lock 9.

On the other hand, the number entered on the keyboard 20 and the control device i
When the number set and registered in oo does not match, the control device f100 outputs an alarm buzzer signal to the alarm buzzer 62, and the alarm buzzer 62 goes off.

Now, regarding the case of unlocking the electronic lock 9 from the outside of the door,
This will be described with reference to the block diagram of FIG. 25 and the flow of FIG. 26. That is, first, the cover 30 is opened. 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. If the cover 30 is not open, a cover open signal is controlled from the cover open/occlusion detection device 35]
is input to the device 100. Next, the user presses the numeric keypad 22 of the keyboard 20 in order according to the four-digit password. Then, the data of the 4-digit password inputted manually is input to the comparison circuit of the control device 100.

In steps 202 to 206 of the flow shown in FIG. 26, it is determined whether the read password is correct. The comparator circuit of the control device 100 compares the stored PIN number with the key-entered number and detects a match or mismatch between the two. If they do not match, 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, thereby informing that the key was 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 209, it is determined whether the cover is open or closed.

If the cover is closed, a cover close signal is sent to the control device 100.
is input. 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, an electronic lock lock signal is output from the control device 100 to the electronic lock 9 in step 212 of the flowchart of FIG. 26, 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 the two conditions are met: the stored number matches the key-entered 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 someone else from knowing the position of the keyboard 20 due to forgetting to close the cover 30 when unlocking the electronic lock 9 and entering the house.

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

Next, the case of locking the door 8 from the outside will be described with reference to the flow shown in FIG. 27 and the block diagram shown in FIG. 25. First, open the cover 30.

Then, in step 301 of the flowchart of FIG. 27, the cover open/close status is read, and in step 302 it is determined whether the cover is open or not. When the cover is opened, a cover opening signal is input to the control device 100. Next, close the cover 30 to hide the keyboard 2°. 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 open/close detection device 35 outputs a cover close 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 shown in FIGS. 17 to 19 and FIG. 15. 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 section 5, whereby the lock lamp 58 is turned on. Furthermore, when the electronic lock 9 is unlocked, the lock lamp 58 is off. If it is not locked, the lock button 59 of the control unit 5 is pressed. Then, a signal is output from the control unit 5 to the control device 1oo, and an electronic lock locking signal is output from the control bag W1100 to the electronic lock 9, so that the electronic lock 9 is locked. 17 to 19 are process diagrams for 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.

When the electronic lock 9 is locked, the lock button 59
Press. Then, a signal is sent from the control unit 5 to
ioo, and further an electronic lock unlock signal is output from the control device 100 to the electronic lock 9, thereby unlocking the electronic lock 9. At this time, the lock lamp 58 goes out.

Also, if an incorrect input is made on the keyboard 20 and the alarm buzzer 62 is sounding, the alarm buzzer button 60 is pressed.

Then, the alarm buzzer runs, the lamp 60 goes out, and furthermore, a signal is output from the control section 5 to the control device 100, and the control is stopped! The alarm buzzer 62 is stopped by the signal from Il@1j100. Furthermore, the alarm buzzer button 60 is pressed again.

Then, the alarm buzzer lamp 60 lights up and the alarm buzzer 62 is newly set. In the set state, if an erroneous 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, the tip of a screwdriver or the like is inserted into the hole 63a of the PIN cover 63 and the PIN cover 63 is removed. Then, the user inserts the tip of a screwdriver or the like into the password dial 64 and turns the password dial 64 to match the predetermined number and change the password.

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.
