  The car 2 that moves up and down in the hoistway is provided with a car doorway, and the car doorway is opened and closed by a car door 3 that is moved horizontally. In addition, a landing entrance 5 is provided at the landing 4 on each floor where the car 2 stops, and the landing entrance 5 is opened and closed by a landing door 6 that is moved horizontally. Here, the landing door 6 is opened and closed in conjunction with the opening and closing of the car door 3.

  In FIG. 1, a state in which a customer 8 using a wheelchair 7 that is a detection target of door opening extension is present at the landing 4 and before entering the car 2 is shown as an example.

  A safety shoe 3a as an obstacle sensor that detects an obstacle at the time of door closing operation is provided at the tip of the car door 3. When it is detected that the safety shoe 3a is pressed, the door opening / closing drive unit 9 of the elevator controls to open the car door 3.

  Further, a door opening extension device 1 is installed from the ceiling of the car 2 through a hanging metal fitting 10 in the vicinity of the upper side of the car door 3 in the car 2. The door extension device 1 is equipped with a camera 11 that captures an area A surrounded by a one-dot chain line in FIGS.

  FIG. 3 is a front view of a cross section of the elevator door opening extension device 1 according to the first embodiment of the present invention. FIG. 4 is a side view of a cross section of the elevator door extension device 1 according to Embodiment 1 of the present invention. Furthermore, FIG. 5 is a control block diagram of the door opening extension device 1 according to Embodiment 1 of the present invention.

  The door extension device 1 according to the first embodiment includes a camera 11, a storage unit 12, an arm 13, a motor 14, a control unit 15, a speaker 16, and a battery 17. The camera 11 is an image pickup device that captures the area A shown in FIGS. 1 and 2 from the predetermined area of the hall 4 to the floor surface portion of the entrance / exit of the car 2.

  The storage unit 12 stores reference image data of a wheelchair 7 or the like that is a detection target in advance.

  The arm 13 is a mechanism that can rotate between the storage position and the operation position shown in FIG. The arm 13 does not block the moving area of the car door 3 in the storage position, but the arm 13 blocks the moving area of the car door 3 by rotating to the operating position, and the car door 3 is closed. It has a configuration that can prevent this. The motor 14 is a drive source that rotates the arm 13.

  The control unit 15 performs a matching process on the image captured by the camera 11 and the reference image data stored in the storage unit 12, and operates the motor 14 based on the matching result, as necessary. The door opening extension is controlled by preventing the car door 3 from closing. Further, the control unit 15 can notify the message via the speaker 16.

  The battery 17 is a power supply source that supplies power to the camera 11, the storage unit 12, the motor 14, and the control unit 15. The battery 17 is configured as a single-use primary battery or a rechargeable secondary battery that is discarded once it is completely discharged.

  Next, a series of operations of the elevator door opening and extending device 1 of the present invention configured as described above will be described in detail according to a flowchart. FIG. 6 is a flowchart showing a series of door opening extension operations executed by the control unit 15 of the elevator door opening extension device 1 according to Embodiment 1 of the present invention.

  First, in step S <b> 101, the control unit 15 extracts target image data such as a wheelchair 7 that matches the reference image data stored in the storage unit 12 from the image of the area A captured by the camera 11. Determine whether or not.

  When determining that the target image data is not extracted, the control unit 15 repeats the process of step S101. On the other hand, when determining that the target image data has been extracted, the control unit 15 proceeds to step S102.

  In step S102, for example, after waiting for 1 second, the control unit 15 extracts target image data in the area A again in step S103, and extracts the target image data extracted in step S103. It is determined whether or not the position has moved in the two directions of the car from the position of the target image data extracted in the previous step S101.

  Here, in step S103, when the target image data itself is not extracted, when the movement is not detected in the target image data, or when movement in a direction other than the two directions of the car is detected, the control unit 15 performs step The process returns to S101.

  That is, when the control unit 15 determines No in step S103, the passenger 8 of the wheelchair 7 is standing still in order to wait for the car 2 in the reverse direction, or temporarily passes in front of the landing 4. This corresponds to determining that the door opening extension device 1 does not need to be operated.

  On the other hand, when the control unit 15 determines in step S103 that the target image data is moving in the two directions of the car, the control unit 15 proceeds to step S104, rotates the motor 14 in the forward direction, and moves the arm 13 from the storage position. Rotate to operating position. Thereby, even if the door closing operation of the car door 3 is started, the car door 3 is opened again by the arm 13 pressing the safety shoe 3a.

  Next, in step S105, the control unit 15 sets an initial value in the counter CNT. In the flowchart of FIG. 6, as an example, 3 is set as an initial value.

  Further, in step S106, the control unit 15 waits for one second, for example, and then in step S107, the target image data in the image of the area A photographed by the camera 11 is in the car 2 inward direction from the previously detected position. It is determined whether or not it has moved to. Note that even when the target image data does not already exist in the image of the area A, the control unit 15 determines that the target image data has not moved in the car 2 inward.

  If the control unit 15 determines in step S107 that the target image data is moving in the direction toward the inside of the car 2, the control unit 15 proceeds to step S108 and determines the position of the wheelchair 7 from the position of the target image data in the area A. It is determined whether or not the customer 8 has completed the movement into the car 2.

  If the control unit 15 determines in step S108 that the user 8 of the wheelchair 7 has completed the movement into the car 2, the process proceeds to step S109. In step S109, the control unit 15 rotates the motor 14 in the reverse direction to rotate the arm 13 from the operating position to the storage position. As a result, the arm 13 that has pressed the safety shoe 3a is retracted from the safety shoe 3a, and the car door 3 is closed by continuing the door closing operation of the car door 3.

  On the other hand, if the control unit 15 determines in step S107 that the target image data has not moved inward in the car 2, the process proceeds to step S110. Then, in step S110, the control unit 15 subtracts 1 from the value of the counter CNT.

  Furthermore, in step S111, the control part 15 returns to the process after step S106, when the value of the counter CNT is not zero. On the other hand, when the counter CNT reaches 0 in step S111, the control unit 15 proceeds to step S109 and rotates the arm 13 to the storage position.

  In addition, when it is determined in Step S108 that the customer 8 of the wheelchair 7 has not completed the movement into the car 2, the control unit 15 returns to the processing after Step S106.

  Here, the control unit 15 proceeds from step S107 to step S110 to step S111, and finally performs the process of proceeding to step S109 when CNT = 0, which corresponds to the following determination. . That is, in step S103, the control unit 15 detects that the customer 8 of the wheelchair 7 is moving in the direction of the car 2 and operates the arm 13 of the door opening extension device 1, but then the car 2 It is necessary to operate the door opening extension device 1 any more because it is determined that the car has no intention to get into the car 2 due to fullness or the like, has stopped on the spot, or has moved to another elevator. This is equivalent to judging that it is not.

  In the above description, 1 second is used as an example of the standby time, and 3 is used as an example of the initial value of the counter CNT. However, the present invention is not limited to such a numerical value, and another standby time or initial value is used. May be set.

  In addition, the control unit 15 reads “A wheelchair customer is on board” through the speaker 16 during the door opening extension operation by the door opening extension device 1. "Please pack it in the back." Thereby, the user 8 of the wheelchair 7 can be smoothly guided into the car 2.

  In the above description, the object to be detected is the wheelchair 7, but the object of the door opening extension is not limited to the wheelchair, and may be, for example, a stroller or a shopping cart.

  By storing the reference image data of the stroller or the shopping cart in the storage unit 12 in advance, the same operation can be performed. This may be appropriately selected according to the use of the place where the elevator is installed.

  The extraction of the target image data is not limited to the matching process using the reference image data. For example, a feature extraction process for extracting a feature portion such as a wheel such as a wheelchair 7 from the captured image is performed. It is also possible to adopt.

  As described above, the elevator door opening extension device according to the present invention detects an obstacle when a car is closed and a camera that captures an area from a predetermined area of a landing to a floor portion of a car entrance and exit. Drive mechanism that activates safety shoe detection, and when target image data such as a wheelchair is extracted from an image taken by a camera, the drive mechanism operates until the target image data completes moving to the car And a control unit for controlling.

  Thereby, when image data, such as a wheelchair, is recognized with a camera, the detection of the obstacle sensor installed in the cage | basket | car can be validated by operating a drive mechanism part. That is, the existing obstacle sensor can be used to regulate the door closing operation of the car, and the door opening can be extended without causing a user such as a wheelchair to perform any operation.

  Further, the control unit activates the drive mechanism when the target image data detects movement toward the car side, and then resumes the operation of the drive mechanism when no movement into the car is detected. .

  As a result, although the arm of the door extension device was operated, the passengers such as wheelchairs were not willing to get into the car because the car was full, etc. When moving to the direction, the arm of the door opening extension device can be returned to the storage position, and the door opening extension can be quickly stopped. Accordingly, it is possible to avoid a decrease in elevator operation efficiency due to the addition of the door extension device.

  Further, the drive mechanism unit can be constituted by an arm that is rotated during operation and blocks a door moving area of the car, and a motor that rotates the arm. Thereby, the mechanism part which presses a safety shoe can be constituted simply. Here, by using a stepping motor as the motor, the configuration of the control unit can be simplified.

  The drive mechanism unit is not limited to motor drive, and the same effect can be obtained even if the storage position and the operation position can be displaced by moving the arm back and forth by a solenoid. .

  Further, the detection target object may include a wheelchair, a stroller, a shopping cart, and the like. Thereby, the convenience of the user who rides with the apparatus which has a wheel which takes time to get in in a cage | basket | car can be improved.

  In addition, the camera, the storage unit, the motor, and the control unit are preferably formed integrally with a battery that is a power supply source.

  With such a configuration, wiring for supplying power from the car becomes unnecessary, and wiring work can be omitted. By adopting such a configuration, for example, it can be easily attached to and detached from an elevator that wants to use the door extension device according to the present invention only for a certain period of time at an event or the like.

  As described above, according to the first embodiment, by performing the configuration shown in FIGS. 1 to 5 and the series of processes shown in FIG. 6, until a passenger such as a wheelchair gets into the car surely. By operating the existing obstacle sensor, it is possible to regulate the door closing operation of the car door and release the restriction of the car door closing operation after getting in. As a result, the door can be extended for an appropriate period of time necessary for the passenger to get into the car without any special operation. You can get into the car with peace of mind.
