BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an automatic door device provided in a toilet for a vehicle shared by a physically handicapped person and a healthy person.

[0002]

2. Description of the Related Art A conventional automatic door device for a toilet for the physically handicapped is described in the book "Living Space for the Handicapped" (p. 44) published by the Japan Rehabilitation Association for the Disabled. As shown in FIG. 4, the door 1, which is an electric hanging door suspended above, is provided with an inner open button 2 a, an inner close button 2 b of an inner operation panel 2 provided on the indoor side, and an outer operation panel 3 provided on the outdoor side. There is one that is operated by the outside open button 3a and the outside close button 3b. In the figure, reference numeral 4 denotes a busy lamp, 5 denotes an emergency switch, 6 denotes a lock confirmation lamp, and 7 denotes an operation method nameplate. When the user presses the inner close button 2b of the inner operation panel 2, the door 1 closes, the in-use lamp 4 is turned on, the electromagnetic lock is activated, and the lock confirmation lamp 6 is turned on. Open button 3 with the middle lamp 4 on
The door 1 does not open even if a is pressed, but opens when the inner open button 2a is pressed. When the emergency switch 5 is turned off, the electromagnetic lock is free and the door 1 can be opened manually. If the user forgets to press the outer closing button 3b, it is automatically closed by a time switch.

[0003]

In the conventional automatic door device, when the inside closing button 2b is pushed out of the room quickly by mischief, the door 1 is locked by the electromagnetic lock even though there is no person in the room.
Is locked. In this locked state, there is a problem that the emergency switch needs to be operated because the door 1 is not opened even if the outside opening button 3a is pressed. Such a problem is likely to occur when shared with a healthy person when it is difficult to use it exclusively for the physically handicapped due to its size, as in a vehicle toilet. An object of the present invention is to provide an automatic door device in which such mischievous operations are difficult to perform.

[0004]

According to the present invention, there is provided an automatic door apparatus in which a control unit controls opening and closing of a door in response to an opening signal and a closing signal by operating an opening and closing operation unit provided inside and outside a room. A first opening / closing operation section for a physically handicapped person provided on the indoor side, a second opening / closing operation section for a healthy person provided on the indoor side, and a third opening / closing operation section provided on the outdoor side. And a manual lock is provided on the door, and from when the first closing signal is received from the first opening / closing operation section until the opening signal is received from the first or second opening / closing operation section, the control section is The opening signal from the third opening / closing operation section is invalidated. In the above means, the manual lock may emit a locking signal in a locked state, and the control unit may invalidate the opening signals from all the opening / closing operation units during the locking by the locking signal. Features.

[0005]

According to the above means, when the user is physically handicapped, the control unit receives the first closing signal when the door is closed by the first opening / closing operation unit after entering the room. Alternatively, the opening signal from the third opening / closing operation unit is invalid until the control unit receives an opening signal when the door is opened by the second opening / closing operation unit. (3) Since the door cannot be opened depending on the opening / closing operation section, no one else carelessly opens the door. Then, when the healthy person performs the closing operation of the second opening / closing operation unit in the room and quickly goes out of the room and closes the door before the door closes, the opening signal from the third opening / closing operation unit is effective, In addition, since the electromagnetic lock and the like do not operate, there is no need to operate the emergency open / close button.

If the user is a healthy person, he enters the room and then operates the second opening / closing operation unit to close the door and then lock the door manually. In this case, when the control unit invalidates the opening signals from all of the opening / closing operation units by the locking signal, the control unit does not operate even when the door is opened, so that an unreasonable opening force can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. This embodiment is an automatic door device between a room and a passage of a toilet for a physically handicapped person and a normal person provided in a vehicle such as a long-distance train. This automatic door device, as shown in FIG.
An opening / closing operation unit is provided on the indoor side for a disabled person.
A push-button device including an opening / closing operation unit 11, a second opening / closing operation unit 12 for a healthy person, and a third opening / closing operation unit 13 provided outside the room for the physically handicapped and a healthy person, each having an open push button and a close push button. The door 14 is opened and closed by a door driving device (not shown), and a manual lock 15 which can be operated indoors with the door 14 closed is provided. Part is provided. In addition, description about a door pinch safety device etc. is abbreviate | omitted. The door drive device is of a suspended electric sliding door type, and the door 1 is driven by an electric command.
4 can be moved between a fully closed position shown by a solid line in the figure and a fully open position shown by a virtual line in the door pocket 16. Manual lock 15
Is a latch which is manually operated, for example. When the lock state is set, a micro switch as an internal lock detection unit is turned on, and a lock detection signal is generated. The control unit is constituted by a microcomputer.

FIG. 2 is a block diagram showing the configuration of the automatic door device. That is, a first opening / closing push button device (first opening / closing operation portion) 11, a second opening / closing push button device (second opening / closing operation portion) 12, a third opening / closing push button device (third opening / closing operation portion) 13,
It comprises a lock detection unit 17, a control unit 18, and a door driving device 19. First open / close push button device 11, second open / close push button device 1
2. When the open push button and the close push button of the third opening / closing push button device 13 are operated, the corresponding open signal and close signal are output to the control unit 18, and the control unit 18 issues an open command and a close command corresponding to the signal. Output to the door driving device 25 to open and close the door 15. For convenience, the open signal output from the first open / close push button device 11 is referred to as a first open signal, the close signal is referred to as a first close signal, and the second and third open / close push button devices have the same input / output circuit. Therefore, a common open / close signal is output. However, when it is necessary to specify this open / close signal, the open / close signal is set to a second open signal or a second close signal in order to distinguish it from the first open / close push button device 11. In the present embodiment, since the second and third opening / closing pushbutton devices 12 and 13 output a common opening / closing signal, a closing signal (first closing signal) from the first opening / closing pushbutton device 11 is output to the control unit 18. When
After that, the opening signals from the second opening / closing push button device 12 and the third opening / closing push button device 13 are invalid until the opening signal (first opening signal) from the first opening / closing push button device 11 is input to the control section 18. Is controlled by the control unit 18. Note that the second and third
When the opening / closing signals of the opening / closing push button devices 12 and 13 are made independent, after the first closing signal from the first opening / closing push button device 11, only the third opening signal of the third opening / closing push button device 13 is invalidated. The second open signal can be made valid. A lock detection signal when the lock detection unit 17 detects the lock is input to the control unit 18, whereby the control unit 18 invalidates the open signals from all of the open / close push button devices 11, 12, and 13. I have. Further, after the door 14 reaches the fully open position, the door 14 is closed when 60 seconds elapse by the built-in timer.

The automatic door device operates as shown in the flowchart of FIG. That is, in step S1, the door 15 is in the fully closed position, and this state is a state where the power is turned on and the door 15 can be automatically opened and closed. In the next step S2, it is determined whether or not locking is being performed, that is, whether or not a locking detection signal has been input. If it is not locked, the process proceeds to step S3 to determine whether or not the lock is being set, that is, the first closing signal of the first opening / closing push button device 11 is input, and the second opening / closing push button device 12, the third opening / closing push button device 13
It is determined whether the open signal from is invalidated. If the lock is not set, the process proceeds to step S4 to determine whether a first open signal or a second open signal from the first, second, or third opening / closing push button device is input. Move to step S5. In step S5, the closed state of the door is maintained, and the process returns to step S2. If the door is locked in step S2, the process proceeds to step S5, the closed state of the door is maintained, and the process returns to step S2.

If the lock is being set in step S3, the process proceeds to step S6, and it is determined in step S6 whether a first open signal from the first opening / closing push button device 11 is input. If the first open signal has not been input, the process proceeds to step S5, and returns to step S2. Therefore, the door is kept closed until the first open signal is input. If the first open signal has been input in step S6, the process proceeds to step S7 to release the lock setting, that is, the state in which the open signals from the second open / close push button device 12 and the third open / close push button device 13 are invalidated. . Then, the process proceeds to step S8 to output an open command to open the door driving device 19, and then proceeds to step S9 to open the door to the fully open position.

The process proceeds from step S9 to step S10 to determine whether or not the second closing signal has been input, ie, whether the second and third signals have been input.
It is determined whether or not a closing signal from the open / close push button devices 12 and 13 is input. If not, the process proceeds to step S11, and in step S11, it is determined whether or not the first closing signal is input. If the input has not been made, the process proceeds to step S12. In step S12, it is determined whether 60 seconds have elapsed. If not, the process proceeds to step S13 to keep the door open, and the process returns to step S10. Therefore, if the closing signal is not input at the fully opened position of the door, the door is kept open until 60 seconds elapse. After 60 seconds, step S1
The process proceeds from Step 2 to Step S15, and a close command is output in Step S15. When the second closing signal is input in step S10, the process proceeds to step S15 to output a closing command, and when the first closing signal is input in step S11, the process proceeds to step S14 to perform step S14. After the lock is set, the first opening / closing operation section 11
When the signal is a close signal, the open signals from the second and third opening / closing operation units 12 and 13 are invalidated, and the process proceeds to step S15 to output a close command.

The process proceeds from step S15 to step S16, and the door 14 starts to close. Next, the process proceeds to step S17, and it is determined whether or not the lock is set. If the lock has been set, the process proceeds to step S18 to determine whether or not the first open signal has been input. If the signal has been input, the process proceeds to step S19, the lock is released in step S19, and an open command is issued in step S20. Then, the process proceeds to step S21, in which the closing direction of the door 14 is reversed to open, and the process returns to step S9. If the first open signal has not been input in step S18, the process proceeds to step S24. In step S22, it is determined whether or not the first or second open signal is input. If the first or second open signal is input, the process proceeds to step S23 to output an open command, and returns to step S9 via step S21. If there is no input of the first or second open signal in step S22, the process proceeds to step S24 to determine whether the door is at the fully closed position. If not, the process returns to step S15 and returns to step S15. If there is, the process returns to step S2.

Since the above operation is performed, when the user is a physically handicapped person using a wheelchair, the user pushes the opening push button of the third opening / closing push button device 13 on the aisle side to open the door 14 to enter the room. When the door 14 is closed by pressing the closing push button of the first opening / closing push button device 11, the door 14 is locked, and the lock is not released until the next push of the opening push button of the first opening / closing push button device 11, so that the lock is particularly locked. You don't have to. In the locked state, the open signals of the first and second opening / closing push button devices 11 and 12 are invalid. When the user is a healthy person, the user similarly enters the room, presses the closing push button of the second opening / closing push button device 12, closes the door 14, and operates the manual lock 15 to lock the door as it is not locked. . In the locked state, the open signal of the third opening / closing push button device 13 is invalid. When exiting, the user unlocks the manual lock 15 and then pushes the opening push button of the second opening / closing push button device 12 to open the door 14 and exit. After going out of the room, both the physically and physically handicapped push the close push button of the third open / close push button device 13 to close the door 14. If the user forgets to press the close button, the button is automatically closed after 60 seconds. Further, even if the close push button of the second open / close push button device 12 for a healthy person is quickly pushed out of the room while the door 14 is open, the locked state is not established, so that normal use is possible thereafter. Therefore, both physically and physically handicapped can be used without any trouble, and there is no mischievous closing and locking when no one is inside.
