Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing operation mechanism for a home door device that opens and closes a movable door installed on a platform, for example. It is related with the opening / closing operation mechanism.

  As an opening / closing operation mechanism of a conventional home door device that opens and closes a movable door, there is the following. The platform door device is composed of a pair of doors installed on the platform and a set of entrance / exit doors that are opened and closed by the doors, and there are a plurality of platform door devices that open and close the entrance / exit along the longitudinal direction of the platform. It is arranged and configured. The opening / closing operation mechanism of the home door device that opens and closes the entrance / exit opens / closes the movable door according to a command from the vehicle, and the passenger passes through the entrance / exit to get on / off.

  Among such platform door device opening / closing operation mechanisms, there is one in which a crew member operation panel is provided in a door pocket of a platform door device installed at, for example, the rearmost of the platform. This crew member operation panel is provided with an opening / closing switch that allows a crew member on board the vehicle to open and close the movable door, and is generally configured as a push button switch.

  This crew control panel is generally used when the vehicle is not equipped with a command device that opens and closes the movable door, but communication between the command device on the vehicle and the platform ground station does not work. It may also be used in emergency situations.

In the following, a case where a command device for opening and closing the movable door of the home door device from the vehicle is not provided will be described as an example. The operation procedure is as follows.
When the vehicle enters the platform, the operator performs a stop operation of the vehicle and stops the vehicle according to the open / close position of the movable door of the home door device. When the vehicle stops at a predetermined position by the operator's operation, the crew operates the movable door open / close switch (push button switch) on the crew operating panel mounted on the door pocket of the platform door device from above the vehicle to move the movable door. Open, then open the vehicle door. When the passenger boarding / exiting is completed, the crew member closes the door of the vehicle, then operates the movable door open / close switch (push button switch) on the crew member operation panel to close the movable door, and the train departs.

Japanese Patent No. 4934227 Japanese Patent No. 3183941

  In the conventional open / close operation mechanism of the home door device described above, when the stop position of the vehicle deviates from a predetermined position, the crew member operates the open / close switch (push button switch) that opens the movable door by getting out of the vehicle. There was a need. In addition, when the crew member cannot reach the opening / closing switch (push button switch), the train is moved to a predetermined position, or in some cases, the crew member gets off the vehicle, and the opening / closing switch (push button switch) from the platform. Had to operate. For this reason, opening and closing of the movable door is delayed, and consequently opening and closing of the door of the vehicle is delayed, passengers getting on and off are delayed, and departure of the vehicle is delayed.

  In addition, when the open / close switch of the platform door device is composed of, for example, a photoelectric tube sensor composed of a projector and a light receiver, it can be moved by holding the hand between the light emitter and the light receiver of the photoelectric tube sensor to block the signal line. Since the door is opened and closed, and the operation range is widened, it is said that the crew can operate even if the vehicle stops.

  However, in such a method of holding the hand over the photoelectric tube sensor, since the optical path cannot be visually observed, there is no certainty in the operation of blocking the optical path by holding the hand, and the actual opening / closing operation is performed. An indicator lamp or the like indicating that the opening / closing operation has been accepted as a circuit is necessary, and the operation itself was not stable. In addition, when dust accumulates on the surface of the photoelectric tube sensor, the range in which the optical path is blocked changes, and there is a possibility that the range in which the opening / closing operation is performed is changed by holding the hand. Furthermore, when some kind of shielding object enters the optical path, there is a problem that the movable door opens and closes alone even though there is no operation by the operator.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a home door that can stably open and close the movable door even when the stop position of the vehicle varies. An opening / closing operation mechanism of the apparatus is provided.
