Since it can be set and set in advance, it helps to improve convenience and safety.

  If the structure of Claim 5 is employ | adopted, since it is a door application and unlocking mechanism in which a vertical lock pin raises / lowers via the circular motion of a rotation arm by the drive of an actuator, the lock pin is used as a door. It can be easily inserted and locked into the lock pin receiving hole formed on the upper surface of the cover, and nevertheless, it is difficult to pull upward from the lock pin receiving hole, resulting in excellent stability of the locked state. .

  If the structure of claim 6 is adopted, since the door opening / closing drive torque motor opens the door for the first time after confirming that the unlocking limit switch of the actuator is in the ON state, troubles such as failure may be caused. There is no risk of it happening, and the locked state of the door can be known from the indoor side by turning on the LED lamp.

  If the structure of claim 7 is adopted, even if the actuator that lifts and lowers the lock pin of the door locking / unlocking mechanism cannot be used in the event of a power failure or other emergency, the actuator can be operated by manual operation of the cylinder lock. Rotating from outside, doors can be locked and unlocked, so there are no security problems.

  If the structure of Claim 8 is employ | adopted, in the process which a door closes, the possibility that a person may be pinched can be prevented reliably, and it is excellent in convenience and safety in use.

  If the structure of Claim 9 is employ | adopted, the physical mechanism of opening and closing of a door, opening and closing, and these electric control means will be in the housing housing of the upper frame part in the opening frame (entrance door attachment frame) of a front door. Since the doors are stored centrally and centrally, the door itself can be made light and a simple makeup with no irregularities on the surface, and the door has excellent design. .

  In addition, the door is a folding door, the base of the door panel on the base end side is suspended by fitting the power take-off shaft on the torque motor side and the hollow input shaft on the door panel side, and the door of the front door panel The door can be opened and closed stably and smoothly in a state where the door is supported at two points (both left and right), because the front part is suspended by a suspension unit that moves along the suspension rail.

It is kept in a state where it is covered with a makeup cap (not shown) that can be freely attached and detached. It goes without saying that the above-mentioned special keys and special tools can be used only by residents (family members) knowing their existence.

  Further, the door application / unlocking mechanism (K) at the substantially intermediate position in the storage housing (H) is used as a boundary, and the torque motor (37) and the gear reduction mechanism as the opening / closing drive source of the entrance door (D). At the eccentric position on the side opposite to (M) (the right side in FIGS. 3 and 4), a stand (63) fixed to the floor board (34) with a plurality of bolts (62) as shown in FIGS. A receiver (64) for receiving a radio signal from a remote control transmitter, which will be described later, and a control box (C) incorporating an opening / closing control board (65) and a power supply board (66) of the entrance door (D); The control / unlocking mechanism control board (67) attached to the control box (C) is stored and installed.

  Then, based on the block diagram showing the electric control circuit of FIG. 25, the overall configuration of the entrance door automatic opening / closing system will be described. A door opening / closing control board (65) serving as a control means for the door opening / closing drive source (torque motor). ) Has an MCU (microprocessor) (68) equipped with ROM, RAM, and other peripheral functions (not shown), a motor driver circuit (69), an input interface (70), and an input / output interface (71). The input interface (70) is connected to an output interface, which will be described later, of a locking / unlocking mechanism control board (67) serving as a control means of the door locking / unlocking mechanism (K). The processor (68) has a closing speed adjustment volume similar to the opening speed adjustment volume (72) of the front door (D). Etc. 73) and opening time setting potentiometer (timer) (74) is connected. On the other hand, the input / output interface (71) is connected to the torque motor (DC brushless motor) (37), which serves as an open / close drive source for the front door (D), and the motor (37) provides a rotation signal and a position signal. The necessary information is fed back (input) to the MCU (68) and the driver circuit (69) of the door opening / closing control board (65).

  The opening time setting volume (timer) (74) sets (adjusts) the opening time in advance when the entrance door (D) is automatically opened and closed automatically by a single input operation to be described later. 22 and 24, the opening speed adjusting volume (72) and the closing speed adjusting volume (73) are arranged in parallel on the surface of the control box (C), as is apparent from FIGS.

  Therefore, a tool required by the contractor at the beginning of newly installing or remodeling the automatic opening / closing system, and then by the user (resident / family member) from the back (indoor side) of the storage housing (H). By rotating these various volumes (72), (73), (74) using the automatic opening speed and closing speed of the front door (D) and the opening time (for example, 0 to 30 seconds). Can be adjusted and set as desired.

  In addition, an application / unlocking mechanism control board (67) which is a control means of the door application / unlocking mechanism (K) is also an MCU (microprocessor) (75), an input interface (76), an output interface (77), and A power supply interface (78) is provided, and an external primary power supply (100V) (79) and a power supply board (66) in the control box (C) are connected to the power supply interface (78). Reference numeral (80) denotes a power on / off switch dedicated to the automatic opening / closing system of the entrance door (D), which includes the power supply interface (78) of the locking / unlocking mechanism control board (67) and the external primary power supply (79). Or it is interposed between breakers.

  The output interface (77) of the locking / unlocking mechanism control board (67) includes an actuator (electric motor) (46) for driving the door locking / unlocking mechanism (K) and the locking / unlocking state. The indoor LED lamp (81) and the outdoor LED lamp (82) to be displayed are connected.

  The indoor LED lamp (81) and the outdoor LED lamp (82) are, as shown in FIGS. 1, 2, 13 and 14, the closed front end (right side in the figure) door panel (PR) of the storage housing (H). ) So as to correspond to the vicinity of the tip end of the bracket.

  Similarly, the receiver (64) and the authentication number (83) of the personal identification number or / and the electronic card key (smart key) are connected to the input interface (76) of the locking / unlocking mechanism control board (67). Yes. A remote control transmitter (84) for transmitting a radio signal to the receiver (64) is a portable type having an automatic opening / closing push button (A) and a manual opening / closing push button (B) as shown in FIG. Thus, a radio signal corresponding to the unique ID code assigned in advance can be transmitted even from a position away from the entrance door (D) by a certain distance (for example, about 5 m).

  When the automatic open / close push button (A) of the remote control transmitter (84) is pressed once, the entrance door (D) is automatically opened and closed. When the button (B) is pressed once, the entrance door (D) opens, and when the button (B) is pressed once more (two times in total), it closes, so the operation of the manual open / close push button (B) It is also possible to keep the entrance door (D) open (by leaving).

  The receiver (64) corresponding to the remote control transmitter (84) omits a detailed description based on the drawing, but stores a unique ID code assigned to each remote control transmitter (84), and accurately stores the ID code. It has a computer function such as an MCU (microprocessor).

  Further, the identification number (83) of the personal identification number and / or the electronic card key is attached to a position next to the entrance door (D) on the outer wall of the house (outside the entrance door of the house) as shown in FIG. 27, the user authenticates the user himself / herself based on the password entered from the numeric keypad (83a) as shown in FIG. 27, or the user uses the electronic card key (not shown) as the authenticator (83). The user is authenticated based on an ID code unique to the electronic card key by being held close to a certain distance (for example, within about 3 cm). (83b) is a cover that surrounds the numeric keypad (83a) so that it is difficult to see from the outside.

  That is, in the automatic opening / closing system of the present invention, the input means that can unlock the door opening / unlocking mechanism (K) manually by inserting a key for locking / unlocking operation from the outside into the key hole of the entrance door (D). If you don't have a remote control transmitter (84) with an ID code registered (stored), an electronic card key, or a user (family member) who stores your PIN (registration number) The unlocking signal of the door applying / unlocking mechanism (K) cannot be input from the outside.

  Furthermore, the input interface (76) of the locking / unlocking mechanism control board (67) includes an indoor automatic opening / closing pushbutton switch (85) manually operated from the room as shown in FIG. 86) and the indoor manual open / close push button switch (87) are connected, the closing limit switch (88) of the entrance door (D), the unlocking limit switch (89), the locking limit switch (90), the room Various sensors such as an inner human sensor (infrared sensor) (91) and an outdoor human sensor (infrared sensor) (92) are also connected.

  Various push button switches (85) (86) (87) manually operated from inside the room, the closing limit switch (88) of the door (D), and the human sensors (91) (92) are all entrance doors (D ) It is not attached to itself and is installed inside the house except the door (D). The entrance door (D) itself is not provided with a handle for opening / closing operation as well as a keyhole for the above-described operation for unlocking / unlocking.

  As with the automatic open / close push button (A) of the remote control transmitter (84), when the indoor automatic open / close push button switch (85) is pressed once, the entrance door (D) automatically opens and closes automatically. This type of input operation is performed from the living room far away from the entrance door (D), the kitchen, the vicinity of the stairs, the study on the floor, and other desired locations in the house. A switch (86).

  In contrast to this, the indoor manual open / close push button switch (87) is the same as the manual open / close push button (B) of the remote control transmitter (84). Means that the entrance door (D) is closed only when it is opened, and is pressed once more (two times in total). In any case, by applying these manual operations, the means for inputting the unlocking signal of the door closing / unlocking mechanism (K) and the power on / off switch (80) dedicated to the automatic opening / closing system are shown in FIG. It is installed on the inner wall near the entrance door (D) and other rooms.

  The indoor side human sensor (91) and the outdoor side human sensor (92) detect whether or not a person is near the door when the entrance door (folding door) (D) is opened and closed. This is to prevent an accident in which a human body is sandwiched between the side door panel (PR) and the opening frame (5). Therefore, as is apparent from FIGS. 4 and 9, the indoor side human sensor (91) Is installed in the vicinity of the end portion (the suspending portion of the door panel) that is biased to either the left or right side (left side in the figure) of the storage housing (H). Similarly, when viewed from the outside of the storage housing (H), it is installed in the vicinity of the end (door tip portion of the door panel) biased to the same side (left side).

  The indoor side human sensor (91) and the outdoor side human sensor (92) in the illustrated embodiment, as suggested by the chain line in FIG. 28, are opened from the front door panel (PR) and the opening from the height of about 2 m, for example. The presence or absence of a person is sensed by projecting infrared rays onto a circular area (Z) of about 240 to 260 mm positioned between the frame (5) and receiving the reflected light. However, the sensing direction can be changed or adjusted appropriately according to the user's wishes.

  Further, the closing limit switch (88) detects the closed state of the front door (D), and the suspension vehicle unit (W) at the front end position (door tip portion) of the front end side (right side in FIG. 3) door panel (PR). ) Is fixedly installed downward from the floor board (34) of the storage housing (H) as shown in FIGS. 13 and 14, and the entrance door (D) depends on the position of the suspension unit (W). On the basis of the output control signal that senses the closed state, the actuator (46) of the door application / unlocking mechanism (K) is rotated in the direction in which the lock pin (48) descends (advances) in FIG. The entrance door (D) is locked.

  In this case, an actuator for driving the lock pin (48) in the door application / unlocking mechanism (K) based on an output signal obtained by detecting the closed state of the entrance door (D) based on the position of the suspension vehicle unit (W). If the rotation control of (46) can be performed so that the entrance door (D) is locked, a photoelectric switch, a proximity switch, and other object detections in place of the (closed) limit switch (88) of the illustrated embodiment. A sensor may be adopted.

  The unlocking limit switch (89) and the locking limit switch (90) are installed in the actuator (46), and the indoor LED lamp (81) is turned on by an output signal from the locking limit switch (90) ( The outdoor LED lamp (82) is lit (preferably green) for a certain period of time (for example, about 10 seconds), while the indoor LED lamp is turned on by an output signal from the unlocking limit switch (89). (81) is turned off.

  The outdoor LED lamp (82) is normally turned off. The indoor LED lamp (81) blinks to notify when an abnormality occurs in the closing limit switch (88), the unlocking limit switch (89) or the locking limit switch (90) (for example, the door is half-opened). It has become.

  Next, FIG. 29 is a flowchart of an operation in which the entrance door (D) is automatically opened by one input operation and automatically closed after a predetermined time has elapsed.

  Based on this, the opening / closing action will be described. As an operation method for inputting the unlocking signal of the front door (D), a method of pressing the automatic opening / closing push button (A) of the portable remote control transmitter (84) from the outside, There are three methods: pressing the numeric keypad (83a) of the personal identification number authenticator (83) and moving the electronic card key (not shown) close to the electronic card key authenticator (83). Pressing the indoor automatic open / close pushbutton switch (85) near the entrance door (D) and the remote remote automatic open / close push in the kitchen, living room, study on the floor, etc. far away from the entrance door (D) There are two methods available: pressing the button switch (86).

  Therefore, in any of the above operating methods, when the first unlock signal is input, the unlock limit switch (89) is turned on at that time (the door is completely unlocked / the door is opened). The MCU (microprocessor) (75) of the locking / unlocking mechanism control board (67) judges (confirms) whether it is in the state) or not (NO state of the unlocking limit switch / door closing) State) until the unlocking limit switch (89) incorporating the driving actuator (46) of the door application / unlocking mechanism (K) is turned on (the door is completely unlocked). Then, it is operated so as to be unlocked (by turning counterclockwise in FIG. 18 and pulling out the lock pin (48) upward).

  On the other hand, if the judgment (confirmation) of the MCU (75) is YES (the unlocking limit switch is on / the door is open), the entrance is determined based on the control signal output from the unlocking limit switch (89). The torque motor (37) for opening and closing the door (D) is rotationally driven in the direction in which the door (D) opens (counterclockwise when folded as a folding door as shown in FIG. 7) to open the entrance door (D). As an example in which this determination (confirmation) is YES, for example, a case where the input of the unlocking signal is received in the middle of the opening of the door (D) can be cited. ) Is operated in the opening direction, so there is no need to wait for an input operation until closing, which is very convenient.

  The opening time of the door (D) is set (adjusted set) as desired by the user by a preset setting volume (timer) (74). The rear door (D) closes automatically.

  In the process of automatically closing the door (D), if there is a danger that the indoor human sensor (91) or the outdoor human sensor (92) senses the presence of a person and pinches the human body Based on the control signals output from the human sensors (91) and (92), the torque motor (37) is rotationally driven (reversed) in the direction in which the door (D) reopens. The door (D) is automatically closed after the preset opening time has elapsed.

  Similarly, in the process of automatically closing the door (D), if any person or other object comes into contact with the door (D), this is an abnormal error signal from the torque motor (37). Feedback (input) to the MCU (68) of the door opening / closing control board (65), and the door (D) is stopped after the torque motor (37) is stopped instantaneously based on the control signal output from the MCU (68). By reversing in the opening direction, accidents involving the object and damage to the door (D) are prevented.

  The reversing action after a momentary stop in the torque motor (37) is performed in exactly the same manner even when the contact phenomenon of the object occurs in the process of opening the door (D). In short, in the process of closing the door (D), double safety is ensured in combination with the prevention effect of the pinching accident by the human body sensor (91) (92).

  In any case, when the door (D) is completely closed as shown in FIG. 9 and the closing limit switch (88) is turned on, the door is based on the output control signal from the closing limit switch (88). The actuator (46) of the locking / unlocking mechanism (K) is operated to lock until the locking limit switch (90) incorporated therein is turned on (the door is completely locked) (FIG. 19). Rotate clockwise and insert lock pin (48) downward).

  When the door (D) is locked, the door opening / closing control board (65) is controlled based on information such as a rotor position signal input (feedback) from the torque motor (37) that is the rotational drive source. The MCU (68) controls the torque motor (37) to be urged to rotate in the pressing direction in which the door (D) is closed (deployed as a folding door).

  When the door (D) is completely locked and the lock limit switch (90) is turned on, the outdoor LED lamp (82) is turned on for a certain period of time (about 10 illustrated above) by a control signal to be output. And the indoor LED lamp (81) is turned on to indicate that the door (D) is locked.

  The automatic opening / closing action of the front door shown in FIG. 29 includes the automatic opening / closing push button (A), the indoor automatic opening / closing push button switch (85), and the indoor remote automatic opening / closing push button switch of the portable remote control transmitter (84). In addition to the method of pressing (86), a method of pressing the numeric keypad (83a) of the personal identification number authenticator (83) or a method of bringing the electronic card key (smart key) close to (passing over) the electronic card key authenticator (83) Even if an input operation is performed, the same result can be obtained.

  Further, FIG. 30 is a flow chart of a manual opening / closing action, that is, a manual opening / closing action that opens the entrance door (D) by the first input operation and closes it by the second input operation.

  In the case of this manual opening / closing action, as an operation method for inputting the unlocking signal, a method of pressing a separate manual open / close push button (B) of the portable remote control transmitter (84) from the outside, There are two methods: a method of pressing an indoor manual open / close pushbutton switch (87) installed near the entrance door (D).

  The manual opening / closing operation will be described. First, when the manual open / close push button (B) or the indoor manual open / close push button switch (87) of the remote control transmitter (84) is pressed first (first time), Whether an unlocking limit switch (89) is in an ON state (a complete unlocking state of the door / a door opening state) when an unlocking signal is input in that operation is also applied to the unlocking / unlocking mechanism. If the MCU (75) of the control board (67) determines (confirms) and the NO (unlock state of the unlocking limit switch / closed state of the door) is NO (the actuator of the door application / unlocking mechanism (K) ( 46) is operated to unlock until the unlock limit switch (89) is turned on.

  On the other hand, if the judgment (confirmation) of the MCU (75) is YES (the unlocking limit switch is on / the door is open), based on the output control signal from the unlocking limit switch (89), the entrance A torque motor (37), which is an opening / closing drive source of the door (D), is rotationally driven in a direction in which the door (D) opens (folding direction as a folding door) to open the entrance door (D). When the door (D) is completely opened (fully opened), the torque motor (37) is kept in a free state (stopped state).

  Therefore, when the manual open / close push button (B) or the indoor manual open / close push button switch (87) of the remote control transmitter (84) used first is pressed again (second time), the torque motor (37) Rotates in the direction of closing the door (D) (deployment direction as a folding door), and closes the door (D). The time until the second input operation is performed is the opening time of the door (D) desired by the user.

  Eventually, when the door (D) is completely closed and the closing limit switch (88) is turned on, the door closing / unlocking mechanism (K) is also turned on based on the output control signal from the closing limit switch (88). Actuator (46) is actuated to lock until its locking limit switch (90) is in the ON state (door fully locked).

  And, when the door (D) is closed and locked, based on the position information input (feedback) from the torque motor (37) which is the rotation drive source to the MCU (68) of the door opening / closing control board (65), The MCU (68) of the door opening / closing control board (65) controls the torque motor (37) to rotate and urge in the pressing direction of closing the door (D) (deploying as a folding door).

  When the door (D) is completely locked and the lock limit switch (90) is turned on, the outdoor LED lamp (82) is turned on for a certain period of time (about 10 illustrated above) by a control signal to be output. And the indoor LED lamp (81) is turned on to indicate that the door (D) is locked.

  29 and 30, when the entrance door (D) is completely closed and locked, the opening / closing drive torque motor (37) closes the door (D) (deployment direction as a folding door). ), The door (D) will not be inadvertently opened (folding direction as a folding door), or there will be no noise that shakes due to strong winds. In particular, the present invention is extremely useful for an entrance door (D) composed of a hanging folding door as in the illustrated embodiment.

  Further, the entrance door (D) in the illustrated embodiment is a hanging folding door, and moves straight along the channel groove-shaped suspension rail (35) via the suspension unit (W). In addition to the smooth and stable operation of the opening and closing action, the open state is folded into a half-folded state. For example, there is no possibility of restricting the entrance area and passage of a hierarchical rental apartment, employee dormitory, and other apartments to be narrow.

  Further, the entrance door (D) does not have a key hole for opening / closing operation and a handle for opening / closing operation, and the torque motor (37), which is an opening / closing drive source of the door (D), or a gear reduction gear. The mechanism (M) as well as the door application / unlocking mechanism (K) and the boards (65), (66), (67), the control box (C), the receiver (64), etc. constituting the electric control circuit, etc. However, it is installed collectively (concentrated) in the storage housing (H) (horizontal upper frame part) of the opening frame (entrance door mounting frame) (5) at the entrance, and that of the entrance door (D) Since it is not attached to itself, it can operate lightly and smoothly in that sense, and since it is not subject to vibration or shock during opening and closing, it is hard to break down, and it is also durable and reliable. It is remarkably excellent.

In this case, FIG. 20 shows an automatic unlocking state and a locking state by driving the actuator (46), and at the time of unlocking, the pair of left and right ropes (54L) (54R) are shown in FIG. On the other hand, at the time of locking, only one of the ropes (54R) on the right side of the figure is loosened as shown in FIG. 20 (c). From inside the room, a tool such as a flat-blade screwdriver or spanner (not shown) is locked to the rotation output shaft (61) of the actuator (electric motor) (46) and rotated, so that it can be manually solved. A locked state and a locked state can be obtained.

Therefore, even in any of the above procedures, when a unlocking signal the earliest is input by hand, in the ON state of the unlocking limit switch (89) (full Kaijojo state of the door) at that time or a whether, MCU of facilities and unlocking mechanism control board (67) (microprocessor) (75) is determined (confirmed) to, if the NO (off state of the unlocking limit switch), door facilities -Actuate the unlocking mechanism (K) drive actuator (46) to unlock until the unlocking limit switch (89) containing the actuator is turned on (completely unlocked door). (Rotate counterclockwise in FIG. 18 and pull the lock pin (48) upward).

On the other hand, if the determination in MCU (75) (confirmation) is set to YES (the ON state of the unlocking limit switch), based on the control signal outputted from the unlocking limit switch (89), front door (D) The opening / closing drive torque motor (37) is rotated in the direction in which the door (D) is opened (counterclockwise when folded as a folding door as shown in FIG. 7) to open the entrance door (D). As an example in which this determination (confirmation) is YES, for example, a case where the input of the unlocking signal is received in the middle of the opening of the door (D) can be cited. ) Is operated in the opening direction, so there is no need to wait for an input operation until closing, which is very convenient.

The manual opening / closing operation will be described.
