[0011] First Embodiment Next, an embodiment of the present invention will be described with reference to the drawings.

[0012] The automatic door opening and closing system 1 shown in Figure 1 is capable of automatically opening and closing a door 9 installed on a wall 8, and includes a controller 2, a door opening and closing device 3, a locking / unlocking device 4, and an unlocking instruction device 5.

[0013] In the automatic door opening / closing system 1 of the present invention, it is assumed that a controller 2 is connected to a commercially available door opening / closing device 3, a locking / unlocking device 4, and an unlocking instruction device 5, and the controller 2 uses the functions originally possessed by the door opening / closing device 3, the locking / unlocking device 4, and the unlocking instruction device 5 to perform the automatic door opening / closing process described below.

[0014] The controller 2 controls the opening and closing operations, and is connected to the door opening and closing device 3, the locking / unlocking device 4, and the unlocking instruction device 5 by wire or wireless communication such as short-range communication. Note that the case where they are connected by wire will be described here.

[0015] In the door opening and closing device 3, when the door 9 is in a closed state, the folded closer arm 34 extends, thereby rotating the door 9 around the hinge 9e as a fulcrum, thereby opening the door 9. Conversely, by folding the extended closer arm 34, the door 9 can be rotated and closed.

[0016] The door opening / closing device 3 is a so-called semi-automatic door opening / closing device 3, in which the door opening / closing motor 33 is driven to open the door in response to an externally supplied door open request signal, and then closes the door after a predetermined door open time has elapsed.

[0017] 3, the locking / unlocking device 4 has a configuration that allows it to be opened and closed automatically by operating a locking mechanism 44 using a locking / unlocking motor 43. The locking mechanism 44 is a so-called latch lock in which a locking latch 44c protrudes from the door 9 and enters a hole provided on the wall 8 side to lock the door when a linkage mechanism 44b operates in response to the rotation of a thumb turn 44a.

[0018] The locking / unlocking device 4 drives the locking / unlocking motor 43 and operates the interlocking mechanism 44b to lock or unlock the door in response to an unlock request signal and a lock instruction signal supplied from the outside. The locking / unlocking device 4 also has a locking / unlocking detection unit 46 that detects whether the locking mechanism 44 is locked or unlocked by, for example, detecting whether electricity is flowing or not or by magnetic detection using a magnet, and a closed door detection unit 47 that detects whether the door 9 is closed.

[0019] The unlocking instruction device 5 is preferably configured to use so-called biometric authentication such as face authentication, fingerprint authentication, or vein authentication, or ID authentication that uses an ID (Identification) device such as a card or remote control and identifies the ID device through short-range communication. Here, a case where a user is authenticated by face authentication will be described.

[0020] The unlock instruction device 5 is entirely controlled by a control unit 51, and acquires the user's facial information using an authentication information acquisition unit 52, which is composed of a camera or the like. The user's registered facial information is pre-registered in a memory unit 55. An authentication unit 51a of the control unit 51 compares the acquired facial information with the registered facial information, and if it is determined that they match, it supplies an unlock request signal.

[0021] Conventionally, unlocking is performed by supplying an unlocking request signal to the locking / unlocking device 4. In the present invention, a controller 2 is connected in advance between the line connecting the unlocking instruction device 5 and the locking / unlocking device 4, and the unlocking request signal is supplied to the locking / unlocking device 4 via the controller 2.

[0022] The controller 2 has a plurality of switches. When the control unit 51 of the unlocking instruction device 5 authenticates the user, the control unit 51 turns on the switch to transmit an unlocking request signal to the locking / unlocking instruction unit 21a of the controller 2.

[0023] The locking / unlocking instruction unit 21a is configured with a switch and is directly or indirectly connected to the locking / unlocking motor 43. When the locking / unlocking instruction unit 21a receives an unlocking request signal, it turns on a switch to transmit the unlocking request signal to the locking / unlocking motor 43.

[0024] The locking / unlocking detection unit 46 detects whether the door is locked or unlocked by detecting the magnetic field of the magnet. The locking / unlocking detection unit 46 is directly or indirectly connected to the controller 2. When the locking / unlocking detection unit 46 detects that the door has been unlocked, it turns on a switch to transmit a signal to the controller 2.

[0025] The locking / unlocking instruction unit 21a of the controller 2 is configured as a switch, and when an unlocking confirmation signal is supplied, the switch is turned on to transmit a door open request signal to the door opening and closing device 3.

[0026] The locking / unlocking instruction unit 21a is directly or indirectly connected to the door opening / closing motor 33. For example, if the door opening / closing device 3 has an external signal input unit (not shown), a connection line from the locking / unlocking instruction unit 21a is connected to the signal input unit. When the door opening / closing motor 33 receives a door-opening request signal, it starts driving to start the door opening operation, and executes the door closing operation after a predetermined door-opening time has elapsed.

[0027] When the door 9 is detected as being in a closed state by magnetic detection of the magnet, the door closed detection unit 47 turns on a switch and transmits a door closed confirmation signal to the controller 2. The door opening / closing instruction unit 21b is connected to the door closed detection unit 47 directly or indirectly.

[0028] When the door close confirmation signal is supplied, the door open / close instruction unit 21b transmits a lock request signal to the locking / unlocking motor 43. The locking / unlocking motor 43 drives the motor to start the locking operation.

[0029] When the locking / unlocking detection unit 46 detects that the locking has been completed, it turns on a switch to transmit a signal to the controller 2.

[0030] In this way, the controller 2 can automatically perform operations from unlocking to opening / closing and locking the door 9 by directly utilizing the functions of the door opening / closing device 3, locking / unlocking device 4, and unlocking instruction device 5, which are already widely available on the market. In addition, since the control unit 21 has a switch configuration, the reliability of the control device can be improved.

[0031] In addition, the door knob latch 9c that is linked to the door knob 9a on the door 9 is designed so that it does not protrude from the door 9 or the latch hole on the wall side (not shown) is blocked so that the door knob latch 9c does not engage with the wall 8.

[0032] Next, the automatic door opening / closing process procedure RT1 executed by the automatic door opening / closing system 1 will be described with reference to the system chart of FIG.

[0033] In step S1, the control unit 51 of the unlocking instruction device 5 authenticates the user and then transmits an unlocking request signal to the controller 2.

[0034] In step S2, the locking / unlocking instruction unit 21a of the controller 2 transmits the unlocking request signal to the locking / unlocking device 4 when the unlocking request signal is supplied.

[0035] In step S3, the locking / unlocking motor 43 of the locking / unlocking device 4 operates the locking mechanism 44 to unlock the door since an unlocking instruction has been given.

[0036] In step S4, the locking / unlocking detection unit 46 of the locking / unlocking device 4 detects that the door has been unlocked and transmits an unlocking confirmation signal to the controller 2.

[0037] In step S5, the door opening / closing instruction unit 21b of the controller 2 transmits a door opening request signal to the door opening / closing device 3, since it has confirmed that the door has been unlocked.

[0038] In step S6, the door opening / closing motor 33 of the door opening / closing device starts driving, and extends the closer arm 34 to open the door 9 and transition to an open state.

[0039] In step S7, when a predetermined open maintenance time has elapsed, the door open / close motor 33 is driven to fold the closer arm 34, thereby shifting the door 9 to a closed state.

[0040] Here, there may be cases where steps S6 and S7 are stopped midway due to, for example, an object being placed on the door. However, the controller 2 cannot recognize this state. Therefore, the controller 2 proceeds to step S9 after step S5 and executes the door-closed standby process SRT2 shown in FIG. 5 (details of which will be described later).

[0041] In step S11, the door closed detection unit 47 of the locking / unlocking device 4 detects that the door 9 has entered the closed state and transmits a door closed confirmation signal to the controller 2.

[0042] In step S12, the locking / unlocking instruction unit 21a of the controller 2 transmits a locking request signal to the locking / unlocking device 4.

[0043] In step S15, the locking / unlocking motor 43 of the locking / unlocking device starts driving in response to the locking request signal, and puts the locking mechanism 44 into a locked state.

[0044] In step S15, the locking / unlocking detection unit 46 of the locking / unlocking device 4 transmits a locking confirmation signal to the controller 2 when the locked state is detected.

[0045] When the lock confirmation signal is supplied, the controller 2 proceeds to the end step and ends the automatic door opening / closing process.

[0046] Next, the door-closed waiting process SRT2 executed in step S9 will be described with reference to the flowchart of FIG.

[0047] In step S9, the control section 21 of the controller 2 proceeds to step S21 of the door-closed standby process SRT2, and starts the door-closed standby process.

[0048] In step S21, the control unit 21 waits for a door-close confirmation signal, and then proceeds to the next step S22.

[0049] In step S22, it is determined whether or not a door close confirmation signal has been received. If a positive result is obtained here, the process proceeds to the next step S29, and then to step S12 of the automatic door opening / closing processing procedure RT1. On the other hand, if a positive result is obtained in step S22, the process proceeds to the next step S25.

[0050] In step S23, the control unit 21 determines whether or not a predetermined standby time has elapsed. If a negative result is obtained here, the control unit 21 returns to step S21 and waits for a door-close confirmation signal.

[0051] If a positive result is obtained in step S22, this means that the door 9 is not closed, and in this case the control unit 21 proceeds to the next step S25.

[0052] In step S25, the control unit 21 transmits a door open request signal to the door opening and closing device 3, and then proceeds to the next step S26.

[0053] In step S26, the control unit 21 determines whether the number of times the door-open request signal has been transmitted exceeds a predetermined number of times. If a positive result is obtained here, the control unit 21 returns to step S21 and waits for a door-close confirmation signal.

[0054] On the other hand, if a positive result is obtained in step S26, the control unit 21 executes error notification processing, such as sounding an alarm, sending a notification to a pre-registered device, or turning on a lamp indicating that locking has not been completed, and then terminates the door close confirmation signal and the automatic door opening / closing processing. Note that the error notification processing is not essential.

[0055] <Second embodiment> Next, a second embodiment will be described with reference to Figures 6 and 7. The second embodiment differs from the first embodiment in that the locking / unlocking device 4 has an acceleration sensor 135, the unlocking instruction device 105 has a switch configuration, and the second embodiment has a lock release mode. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description of the same parts will be omitted.

[0056] The door opening / closing device 103 used is a so-called semi-automatic door opening / closing device that has the function of driving the door opening / closing motor 33 to open the door when the acceleration sensor 35 detects movement of the door, and then closing the door after a predetermined door opening time has elapsed.

[0057] The unlock instruction device 105 has two physical switches: a normal switch 152 and a lock release switch 153. When the normal switch 152 is operated by a user, the automatic door opening and closing system 101 executes the automatic door opening and closing process in the same manner as in the first embodiment.

[0058] On the other hand, when the unlocking switch 153 is operated, the automatic door opening and closing system 101 executes the unlocking process in accordance with the automatic door opening and closing program and the unlocking process procedure RT3 shown in FIG.

[0059] When the unlocking switch 153 is operated, the unlocking instruction device 105 starts the unlocking process and transmits a door open signal to the controller 102 in step S51.

[0060] The controller 102 and the locking / unlocking device 4 execute steps S3 to S5 in the same manner as in the automatic door opening / closing process (FIG. 4).

[0061] Here, the locking / unlocking device 4 is configured to perform a locking operation on the door after a predetermined unlocking maintenance time has elapsed, even if the door is not opened or closed. Therefore, the controller 102 transmits a door open request signal again before the unlocking maintenance time has elapsed, so that the locking / unlocking device 4 does not perform the locking operation.

[0062] In step S56, the controller 102 repeatedly transmits an unlock request signal to the locking / unlocking device 4 at intervals shorter than the unlock maintenance time. This allows the unlocked state of the locking / unlocking device 4 to be maintained for a long period of time.

[0063] In step S57, when the door opening and closing device 103 detects through the acceleration sensor 135 that the door 9 has moved as a result of the user pushing or pulling the door 9, the process proceeds to step S57.

[0064] In step S58, the door opening and closing device 103 drives the door opening and closing motor 33 to extend the closer arm 34 and start the door opening operation.

[0065] In step S59, when the open maintenance time has elapsed, the door opening and closing device 103 drives the door opening and closing motor 33 to fold the closer arm 34 and transition the door 9 to a closed state.

[0066] This unlocked state is maintained until the unlocking switch 153 is operated again or the normal switch 152 is operated.

[0067] <Third embodiment> Next, a third embodiment will be described with reference to Figures 8 and 9. The third embodiment differs from the first embodiment in that the door opening and closing device 203 has a battery 235 and has a door open mode and a power outage mode. In the third embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and descriptions of the same parts will be omitted.

[0068] The automatic door opening and closing system 201 of this embodiment detects that the power supply has been stopped and performs a door closing operation, making it possible to use the system as a fire door.

[0069] Specifically, the controller 202 has a power failure detection unit 226 which is a separately configured board, and the unlock instruction signal supplied from the unlock instruction device 5 is supplied to the power failure detection unit 226.

[0070] When power is being supplied, the power failure detection unit 226 supplies the supplied unlock instruction signal as is to the control unit 221. As a result, when power is being supplied, the automatic door opening and closing system 201 executes the automatic opening and closing process in the same manner as in the first embodiment.

[0071] On the other hand, when the supply of power is stopped, the power failure detection unit 226 supplies a door close request signal to the control unit 221. The door opening and closing device 203 has a battery 235, and the door opening and closing motor 33 can be driven for a certain period of time even during a power failure using the power from the battery 235. The control unit 221 transmits the door close request signal as is to the door opening and closing motor 33 of the door opening and closing device 203. This power failure detection unit 226 stops supplying all door open request signals to the door opening and closing motor 33 during the power failure.

[0072] As a result, in the automatic door opening and closing system 201, the door 9 can be closed during a power outage, regardless of whether the door is open or closed.

[0073] The power failure detection unit 226 may be provided as part of the door opening / closing device 203. If the door opening / closing device 203 has an acceleration sensor (not shown), the power failure detection unit 226 is connected so that a door open request signal supplied from the acceleration sensor is supplied to the door opening / closing motor 33 via the power failure detection unit 226. In this case, when the door 9 is opened during a power failure, the door open request signal is not supplied to the door opening / closing motor 33.

[0074] Furthermore, the automatic door opening and closing system 201 in this embodiment has a door open mode. The controller 202 is connected to an external door open switch 229, and when the door open switch 229 is operated, the system transitions to the door open mode.

[0075] The controller 202 has a power outage detection unit 226 which is a separate board from the control unit 221, and the unlocking request signal supplied from the control unit 51 of the unlocking instruction device 5 is transmitted to the controller 202 via the power outage detection unit 226.

[0076] In the door open mode, the control unit 221 executes the door open mode to open the door 9 by continuously transmitting a door open request signal to the door opening and closing device 203. Note that the door open request signal does not have to be continuous, and the door open request signal may be repeatedly transmitted before the door opening and closing device 103 moves to the door closing operation, i.e., at intervals shorter than the door open time.

[0077] This door open mode is cancelled when the door open switch 229 is operated, and a door open cancel signal is supplied from the door open switch 229 to the control unit 221, and the mode transitions to the normal mode.

[0078] That is, as shown in FIG. 9, when a door open signal is supplied from the door open switch 229, the control unit 221 of the controller 202 transitions to the door open mode and waits for the start of the automatic door opening / closing process in the door open mode.

[0079] The automatic door opening / closing system 201 starts the automatic door opening / closing process in response to a user's operation on the unlocking instruction device 5, and executes steps S1 to S6 in the same manner as in the first embodiment.

[0080] In step S6, after the door opening operation is started by the door opening / closing device 203, the controller 202 continuously transmits a door closing request signal at the timing when the door opening / closing device 203 transmits a door opening request signal before starting the door closing operation.

[0081] When the door-open cancel signal is supplied in step S93, the controller 202 proceeds to the next step S93 and stops transmitting the door-open request signal.

[0082] In step S7, the door opening and closing device 203 starts a closing operation when a predetermined opening waiting time has elapsed since the end of the opening operation in response to the last door-opening request signal.

[0083] In step S94, when the controller 202 confirms that the door 9 has been closed, the process proceeds to the next step S12. The automatic door opening and closing system 201 executes steps S12 to S16, and ends the automatic door opening and closing process in the door open mode.

[0084] <Fourth embodiment> Next, a fourth embodiment will be described with reference to Fig. 10. The fourth embodiment differs from the first embodiment in that it has an interlocking stop switch 253. In the third embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description of the same parts will be omitted.

[0085] The automatic door opening / closing system 301 has an unlocking and interlocking switch 229 in addition to an interlocking stop switch 229, and in addition to a door opening mode, has an interlocking and unlocking mode in which the door remains in an unlocked state.

[0086] The interlock stop switch 356 is a switch that physically cuts off the connection between the controller 2 and the door opening and closing device 3.

[0087] For example, the unlocking interlock switch 229 and the interlocking stop switch 356 are installed on the wall as physically operable switches.

[0088] When the interlocking stop switch 356 and the unlocking / interlocking switch 229 are OFF, the automatic door opening / closing system 301 executes the automatic door opening / closing process in the same manner as in the first embodiment.

[0089] On the other hand, when the unlocking and interlocking switch 229 is ON, the automatic door opening and closing system 301 transitions to the door opening mode in the same manner as in the third embodiment.

[0090] Furthermore, when the unlocking switch 353 is OFF, the automatic door opening / closing system 301 transitions to the interlocking / unlocking mode. When the unlocking switch 353 is ON, the interlocking with the door opening / closing device 3 is cut off, so that only the operation with the locking / unlocking device 4 can be interlocked. Therefore, the automatic door opening / closing system 301 only performs the unlocking and locking operations in response to the unlocking request signal.

[0091] As a result, the automatic door opening and closing system 301 can execute only the unlocking and locking operations in response to user operations, without performing the door opening and closing operations.

[0092] <Actions and effects> The following describes the features of the inventions extracted from the above-described embodiments, while indicating problems and effects as necessary. Note that, for ease of understanding, corresponding configurations in the above-described embodiments are indicated in parentheses as appropriate, but the specific configurations indicated in parentheses are not limited to these. Furthermore, the meanings and examples of terms described in each feature may also be applied as the meanings and examples of terms described in other features described in the same wording.

[0093] In the above configuration, the automatic door opening / closing controller (controller 2) is installed on a door (door 9) that opens and closes in a rotational direction around the hinge (hinge 9e) of the present invention as a fulcrum, and is connected to a locking / unlocking device (locking / unlocking device 4) that unlocks the door in response to an unlock request signal and locks the door in response to a lock request signal, an unlocking instruction device (unlocking instruction device 5) that supplies the unlock request signal in response to a user's operation, a door opening / closing device (door opening / closing device 3) that automatically opens the door in response to an open door request signal and then automatically closes the door, and a closed door detection device (closed door detection unit 47) that detects that the door is closed and supplies a closed door confirmation signal. a locking / unlocking instruction unit (locking / unlocking instruction unit 21a) that transmits the unlocking request signal to the locking / unlocking device when the unlocking request signal is supplied from the unlocking instruction device; a door opening / closing instruction unit (door opening / closing instruction unit 21b) that transmits the door open request signal to the door opening / closing device when an unlock confirmation signal indicating that the door has been unlocked is received from the locking / unlocking device, The locking / unlocking instruction unit is characterized in that, when the door close confirmation signal is supplied from the door close detection device, it transmits the locking request signal to the locking / unlocking device.

[0094] Currently, various unlocking instruction devices are on the market, such as those that use ID devices using biometric authentication or near-field communication. However, these unlocking instruction devices only unlock the door. Furthermore, semi-automatic door opening and closing devices require manual operation of the door after unlocking. When combining these devices, the user is required to open the door slightly after unlocking.

[0095] In the present invention, the automatic door opening / closing controller controls the entire system, opening the door after confirming that it is unlocked, and locking the door after confirming that it is closed.This allows the door to be opened and closed automatically regardless of the locking and opening / closing timing of each product, improving user convenience and allowing an automatic door opening / closing system to be built as a retrofit by utilizing the unlocking instruction device and door opening / closing device that have already been installed.

[0096] In the automatic door opening / closing controller, the door opening / closing instruction unit If the door close confirmation signal is not supplied even after the door close standby time has elapsed after transmitting the door close request signal, the door open request signal is transmitted again to the door opening and closing device, The locking / unlocking instruction unit is characterized in that, when the door close confirmation signal is supplied from the door close detection device, it transmits the locking request signal to the locking / unlocking device.

[0097] This prevents the unlocked door from remaining open if the door does not close due to some accident, thereby improving security.

[0098] The locking / unlocking device is configured to automatically perform a locking operation even if the door is not opened or closed after the unlocking maintenance time has elapsed, The unlock instruction unit When the unlock instruction device supplies an unlock signal in response to a user's operation, the unlock request signal is repeatedly transmitted to the locking / unlocking device at intervals shorter than the unlock maintenance time.

[0099] This allows the locking / unlocking device to be in an unlocked state, so that, for example, in a situation where a large number of customers come, the reception staff does not have to respond to each one one by one, thereby improving user convenience.

[0100] The automatic door opening / closing controller is characterized by having an interlocking stop switch connected between the door opening / closing instruction unit and the door opening / closing device, and capable of cutting off the connection between the door opening / closing instruction unit and the door opening / closing device in response to a user's operation.

[0101] This allows the automatic door opening and closing system to operate only the locking / unlocking device, allowing the user to freely set only the locking and unlocking functions.

[0102] In the automatic door opening / closing controller, the door opening / closing instruction unit When a power outage is detected, a door close request signal is sent to the door opening and closing device.

[0103] This allows the door to be closed quickly in the event of a power outage, so the automatic door opening / closing controller can also be used for fire doors.

[0104] <Other embodiments> Although not specifically mentioned in the above embodiment, if the lock confirmation signal is not supplied within a predetermined lock waiting time, the lock request signal may be transmitted again. This improves the reliability of locking in the event that locking fails accidentally due to misalignment of the door, etc.

[0105] In the above embodiment, the control unit 21 of the controller 2 has a switch configuration, but it may also have an IC circuit configuration using an IC (integrated circuit) chip, etc. Even in this case, the same effects as those of the above embodiment can be obtained.

[0106] In the second embodiment described above, the case where the locking / unlocking device 4 is left unlocked is described, but for example, as shown in Figure 11, after step S7, it is also possible to execute a door opening mode in which the door 9 is opened by repeatedly sending a door opening request signal at intervals shorter than the door opening time before the door opening / closing device 3 moves on to the door closing operation.

[0107] In the second embodiment described above, the door 9 is opened and closed semi-automatically in response to a user's operation on the door 9 in the unlocked state, but the present invention is not limited to this. For example, the door 9 can be opened and closed automatically in response to a user's operation. In this case, a separate physical switch may be provided, and automatic opening and closing is also possible using an authentication information acquisition unit, a normal switch, or a lock release switch. [Industrial Applicability]

[0108] The present invention can be applied to the automatic opening and closing of doors installed at the entrances of buildings or rooms such as offices or apartment buildings. [Explanation of symbols]
