Embodiment 1 FIG.
1 to 3 relate to Embodiment 1 of the present invention. FIG. 1 is a perspective view of a car doorway to which an elevator door sensor device is applied, FIG. 2 is a sectional view of the car doorway, and FIG. It is a block diagram which shows the functional structure of this door sensor apparatus.

  FIG. 1 shows a state where the car entrance / exit side is viewed from the inside of a car room 10 of a car installed in a hoistway (not shown) of the elevator. FIG. 2 is a sectional view of the car entrance / exit portion. The car room 10 is a substantially rectangular parallelepiped space surrounded by a wall surface, a floor surface, and a ceiling surface. A car doorway 11 is provided in front of the car room 10. The car doorway 11 is an opening provided in the car room 10.

  A car door 12 is provided at the car doorway 11. The car door 12 is for opening and closing the car doorway 11. Here, it is assumed that the car door 12 is of a single opening type. That is, the car doorway 11 is opened by moving the car door 12 in the direction indicated by the arrow of “door opening direction” in FIGS. 1 and 2. In addition, the car doorway 11 is closed by the car door 12 moving in the direction opposite to the “door open direction” arrow.

  On the side of the direction in which the car door 12 moves when the door is opened (that is, the direction indicated by the arrow of “door opening direction” in FIGS. 1 and 2) and on the inner side of the car room 10, a vertical column 20 is provided. Is provided. This vertical column 20 forms the edge part of the door pocket side in the left and right of the car doorway 11.

  The vertical column 20 includes a door pocket side wall surface 21 and a sleeve wall surface 22. The door pocket side wall surface 21 is a side surface facing the car doorway 11 of the vertical column 20. Therefore, it can be said that it is this door pocket side wall surface 21 that directly forms the edge of the car doorway 11 on the door pocket side. The sleeve wall surface 22 is a side surface connecting the door pocket side wall surface 21 and the inner wall surface of the cab 10.

  An in-car operation panel 30 is installed on the sleeve wall surface 22. The in-car operation panel 30 is provided with a destination floor button for registering a destination floor desired by a user in the car room 10, and a door opening button and a door closing button for opening and closing the car door 12. Yes.

  A touch sensor unit 40 is provided on the door pocket side wall surface 21 of the vertical column 20 continuously in the vertical direction. The vertical dimension of the touch sensor unit 40 is, for example, 1000 mm.

  A lamp 50 is provided at a position near the touch sensor unit 40 on the door pocket side wall surface 21 of the vertical column 20. The lamp 50 is arranged in the vertical direction in parallel with the touch sensor unit 40. The vertical dimension of the lamp 50 is substantially the same as that of the touch sensor unit 40.

  Here, the touch sensor unit 40 is disposed closer to the car door 12 than the lamp 50. Conversely, the lamp 50 is disposed closer to the sleeve wall surface 22 than the touch sensor unit 40.

  Next, a functional configuration of the elevator door sensor device will be described with reference to FIG. The touch sensor unit 40 is controlled by the sensor control unit 60. The sensor control unit 60 detects that a part of a human body is in contact with the touch sensor unit 40. As the touch sensor unit 40, for example, a pressure-sensitive type can be used, and a capacitive type can also be used. Of course, other known methods can be used.

  When a pressure-sensitive type is used as the touch sensor unit 40, the sensor control unit 60 causes the touch sensor unit 40 to detect the human being based on a signal output from the touch sensor unit 40 according to a pressure change applied to the touch sensor unit 40. It is possible to detect that a part of the body has come into contact.

  Further, when a capacitance type is used as the touch sensor unit 40, the sensor control unit 60 causes the capacitance in the touch sensor unit 40 due to a part of a human body coming into contact with the touch sensor unit 40. Based on this change, it is possible to detect that a part of a human body is in contact with the touch sensor unit 40.

  The sensor control unit 60 does not always detect that a part of a human body has touched the touch sensor unit 40, but activates the function of the touch sensor unit 40 only for a predetermined effective time. Thus, it is detected that a part of a human body has come into contact with the touch sensor unit 40.

  This effective time is set between the time when the car door 12 of the car doorway 11 starts the door opening operation and the time when the car door 12 is fully opened. Specifically, for example, here, the effective time is set from the time when the car door 12 starts the door opening operation in the fully closed state to the time when the car door 12 reaches 200 mm before the fully open position.

  The door opening / closing operation of the car door 12 is controlled by the door control unit 70. More precisely, the door opening / closing operation of the car door 12 is driven by a door motor (not shown), and the door controller 70 controls the door opening / closing operation of the car door 12 by controlling the operation of the door motor.

  The door control unit 70 reverses the door opening operation of the car door 12 when the sensor control unit 60 detects that a part of the human body has come into contact with the touch sensor unit 40 during the effective time. That is, after the door opening operation of the car door 12 is stopped, the car door 12 is closed in reverse. Note that the door opening operation of the car door 12 may be simply stopped without reversing the door opening operation of the car door 12.

  The lighting state of the lamp 50 is controlled by the lamp control unit 80. The lamp control unit 80 notifies the user that the lamp 50 is in the effective time by turning on or reducing the lamp 50 during the effective time. That is, the lamp 50 and the lamp control unit 80 constitute notification means for notifying the user that the effective time is in effect.

  In addition to using such a lamp 50 as this notification means, for example, a predetermined message from the speaker, for example, “the door stops when touched”, or a similar message is displayed on a liquid crystal display or the like. You may comprise so that it may display on an apparatus. Note that a message such as “The door will stop when touched while the lamp is on” may be posted in the vicinity of the touch sensor unit 40 in advance.

  In the elevator door sensor device configured as described above, the lamp control unit 80 turns on the lamp 50 when the fully closed car door 12 starts to open and enters the valid time. The user can know that the function of the touch sensor unit 40 is effective by lighting the lamp 50 or the like.

  In addition, while the car door 12 is open and during the effective time, foreign matter (for example, a bag carried by the user, clothes of the user, etc.) is sandwiched between the car door 12 and the vertical column 20. If the user touches the touch sensor unit 40 by hand, for example, the sensor control unit 60 detects that a person, that is, a part of the user's body has touched the touch sensor unit 40. When the sensor control unit 60 detects that a part of the user's body is in contact with the touch sensor unit 40 during the effective time, the door control unit 70 reverses the door opening operation of the car door 12.

  In addition, even if a foreign object is actually drawn between the car door 12 and the vertical column 20, if the user feels such danger, the user touches the touch sensor unit 40. The door opening operation of the car door 12 can be reversed to prevent foreign objects from being drawn in.

  In the above description, the car door 12 is a single door, but may be a double door. In the case of a double door, both vertical columns on the left and right sides of the doorway are on the door pocket side. Therefore, in this case, the touch sensor unit and the lamp may be provided with both vertical column door pocket side walls.

  In the above example, the door sensor device is applied to the car doorway 11 and the car door 12. However, the door sensor device according to the present invention can be applied to the doorway and the door of the landing. When applied to the entrance / exit of the hall and the door, the touch sensor unit and the lamp are provided in the vertical frame on the door pocket side in the three-way frame of the hall.

  The elevator door sensor device configured as described above continuously extends in the vertical direction on the door-bag side wall surface 21, which is a side surface facing the doorway of the vertical column 20 that forms the edge on the door-bag side on the left and right sides of the doorway 11 of the elevator. During a predetermined effective time from when the touch sensor unit 40 provided and the door 12 of the doorway 11 starts the door opening operation until the door 12 fully opens, a part of the human body is placed on the touch sensor unit 40. When the sensor control unit 60 that detects contact and the sensor control unit 60 detects that a part of a human body has contacted the touch sensor unit 40 during the effective time, the door 12 opens. And a lamp 50 and a lamp control unit 80, which are notification means for notifying the user that the effective time is in effect.

For this reason, when a foreign object is likely to be pinched between the door and the vertical column when the door is opened, the user touches the touch sensor unit, regardless of whether the foreign object is conductive, It is possible to prevent foreign matter from being caught between the door and the vertical column.
In addition, when the user tries to touch the touch sensor part on the bag by providing the touch sensor part continuously in the vertical direction on the side facing the doorway of the vertical column that forms the door pocket side edge of the doorway The touch sensor unit can be contacted easily and reliably.
