  When the landing 4 arrives at the landing 3, the landing-side position detection device 41a and the riding-side position detection device 41b face each other. The level difference detection unit 41 is based on the relative positional relationship between the landing side position detection device 41a and the landing side position detection device 41b, and a level difference between the movable floor plate 45 and the landing 3 (that is, the landing floor 31) described later. Is detected. Further, the step detection unit 41 detects a step range (that is, the size of the step) between the movable floor plate 45 and the landing 3. Information on the level difference detected by the level difference detection unit 41 is sent to the car floor control unit 15a of the elevator control panel 15 as a level difference signal. The car floor control unit 15a recognizes the existence of the step and the step range by receiving the step signal.

  The movable car floor 42 is an additional car floor that is additionally installed on a so-called normal car floor 22 and can be additionally installed in an existing elevator. The movable car floor 42 is installed in the car room 23, for example. The movable car floor control device 43 is provided, for example, on the car of the riding rod 4 and controls the movable car floor 42.

  FIG. 4 shows details of the movable car floor 42. As shown in FIG. 4, the movable car floor 42 includes a movable floor plate 45, a movable floor expansion / contraction unit 46, a movable plate 47, and a movable plate control unit 48. The movable floor plate 45 is provided on the car floor 22 and forms the floor of the car room 23 in place of the car floor 22. The movable floor plate 45 is provided over the entire surface of the car floor 22 except for the car sill 28, for example.

  The movable floor plate 45 includes a movable floor plate main body 51 and a movable end 52 provided at a portion facing the landing 3. The movable end 52 is, for example, at least partially flexible and can be tilted in the vertical direction. The movable floor board main body 51 is formed to be non-movable, for example, and is not inclined unlike the movable end 52.

  The movable floor expansion / contraction part 46 is provided between the car floor 22 and the movable floor plate 45. The movable floor expansion / contraction part 46 is provided in parallel with the movable floor board 45 over the entire surface of the car floor 22 except for the car sill 28, for example. The movable floor expansion / contraction section 46 includes a movable floor expansion / contraction section main body 53 and an expansion / contraction end section 54 provided below the movable end section 52 of the movable floor plate 45. The expansion / contraction end portion 54 can extend and contract in the vertical direction in order to incline the movable end portion 52 of the movable floor plate 45. The movable floor expansion / contraction portion main body 53 is disposed below the movable floor plate main body 51 and is formed non-movable, for example, and does not expand / contract unlike the expansion / contraction end portion 54.

  The movable end 52 of the movable floor plate 45 is controlled to be raised and lowered by the movable floor expansion / contraction part 46. That is, the movable floor expansion / contraction part 46 inclines the movable end part 52 of the movable floor board 45 upward and downward. As shown in FIG. 5, when the telescopic end portion 54 rises (or extends in the vertical direction), the movable end portion 52 of the movable floor plate 45 faces upward (that is, the height increases as it approaches the landing 3). Tilt. On the other hand, as shown in FIG. 6, when the telescopic end portion 54 is lowered (or contracted in the vertical direction), the movable end portion 52 of the movable floor plate 45 is directed downward (that is, as the height approaches the landing 3, the height decreases). To) lean.

  As shown in FIG. 4, the movable car floor 42 is installed on the car floor 22. Therefore, in order to prevent a step between the hall 3 and the movable car floor 42, the hall threshold 34 is higher than the car threshold 28 by the thickness of the movable car floor 42. For this reason, a gap larger than at least the width of the car sill 28 is generated between the landing sill 34 and the movable floor plate 45. In order to narrow the gap between the landing threshold 34 and the movable floor plate 45, a movable plate 47 is provided. In other words, the movable plate 47 is provided to reduce the level difference generated between the landing threshold 34 and the car threshold 28.

  As shown in FIG. 4, the movable plate 47 is provided at the movable end 52 of the movable floor plate 45. The movable plate 47 can advance and retreat along the direction toward the landing 3 (that is, the horizontal direction). More specifically, the movable plate 47 is movable in a first position (see FIG. 3) waiting at a position where the movable plate 47 does not interfere with the riding door 24 (a position inside the car room 23 relative to the riding door 24), and the landing 3. It is possible to advance and retreat between a second position (see FIG. 4) that has advanced toward the landing 3 so as to fill a gap with the floor plate 45. The movable plate 47 located at the second position runs on the car sill 28 so as to cross the riding door 24.

  The movable plate control unit 48 is provided in the movable floor expansion / contraction unit 46. The movable plate controller 48 is connected to the movable plate 47 and moves the movable plate 47 back and forth between the first position and the second position.

  The car floor control unit 15 a of the elevator control panel 15 controls the movable car floor 42 via, for example, the movable car floor control device 43. The car floor control unit 15a receives the detection result from the door position detection unit 29, recognizes the open / closed state of the riding door 24, and synchronizes with the recognized open / closed state of the riding door 24 to move the movable plate control unit. 48 is controlled to move the movable plate 47 back and forth.

  More specifically, the car floor control unit 15a waits the movable plate 47 in the first position when the riding door 24 is closed, and moves the movable plate 47 to the second position when the riding door 24 is opened. The movable plate controller 48 is controlled so as to move forward. When the riding door 24 is closed, the movable plate 47 is moved back to the first state again so that the movable plate 47 does not contact the riding door 24.

  In addition, the car floor control unit 15a receives the detection result regarding the presence of the step between the movable floor plate 45 and the landing 3 and the step range from the step detection unit 41, and recognizes the presence and the size of the step. When the car floor control unit 15a recognizes the presence of the level difference based on the detection result of the level difference detection unit 41, the car 4 of the elevator 2 remains stopped, and the movable floor plate 45 is oriented to cancel the level difference. The movable floor expansion / contraction part 46 is controlled to incline the movable end part 52.

  Further, the car floor control unit 15a calculates the inclination angle of the movable end portion 52 suitable for eliminating the step, based on the step range detected by the step detection unit 41, and the movable end portion up to the calculated inclination angle. 52 is tilted.

Next, the operation and action of the car floor control device 1 will be described.
First, when the landing 4 arrives at the landing 3 on the destination floor, the step detection unit 41 stops so that there is no step between the landing 3 and the landing 4. The state of the movable car floor 42 in this case is shown in FIG.

  When the riding board 4 arrives at the landing 3 and the riding door 24 starts to open, the door position detection unit 29 detects the opening of the riding door 24. The door position detection unit 29 sends a detection result related to the position of the riding door 24 to the car floor control unit 15 a of the elevator control panel 15. The car floor control unit 15 a controls the movable plate control unit 48 to advance the movable plate 47 at a timing that does not interfere with the riding door 24 in accordance with the opening of the riding door 24.

  The movable plate control unit 48 that has received the command from the car floor control unit 15a advances the movable plate 47 from the first position to the second position based on the command. Thereby, the clearance gap between the boarding sill 34 and the movable floor board 45 is reduced.

  As shown in FIG. 4, when there are few passengers getting off from the landing 4 to the landing 3, there is almost no change in the load in the car, so there is almost no step between the landing 3 and the riding 4. At this time, the movable floor expansion / contraction part 46 is not particularly driven, and the movable floor plate 45 is kept flat without being inclined.

  On the other hand, as shown in FIG. 5, when a large number of passengers get on the landing 4 from the landing 3, the load in the car becomes heavy, so that the movable car floor 42 becomes lower than the landing 3. The step range at this time is detected by the step detection unit 41 and recognized by the car floor control unit 15a. And the control which raises the expansion-contraction edge part 54 of the movable floor expansion-contraction part 46 according to the part of the level | step difference recognized by the car floor control part 15a is performed. Thereby, the riding end 4 itself of the elevator 2 is stopped, and the movable end portion 52 of the movable floor plate 45 is inclined obliquely upward, and the step between the movable floor plate 45 and the landing 3 is eliminated.

  Also, as shown in FIG. 6, when a large number of passengers get off from the landing 4 to the landing 3, the load in the car becomes lighter, so that the movable car floor 42 becomes higher than the landing 3. The step range at this time is detected by the step detection unit 41 and recognized by the car floor control unit 15a. And the control which the expansion-contraction edge part 54 of the movable floor expansion-contraction part 46 descend | falls according to the range of the level | step difference recognized by the car floor control part 15a is performed. As a result, while the elevator 4 itself of the elevator 2 is stopped, the movable end 52 of the movable floor plate 45 is inclined obliquely downward, and the step between the movable floor plate 45 and the landing 3 is eliminated.

  Further, the car floor control unit 15a is configured to retract the movable plate 47 from the second position to the first position at a timing that does not interfere with the riding door 24 before the closing of the riding door 24 begins. The movable plate control unit 48 is controlled. In the present embodiment, the inclination of the movable floor plate 45 and the advancement / retraction of the movable plate 47 are automatically performed.

  The elevator car floor control device 1 having such a configuration can be added to an already installed elevator, and the safety of the elevator can be further improved. That is, the car floor control device 1 includes a movable car floor 42 and a movable car floor control device 43 that can be additionally installed on the hall 3 and the landing 4, and can be additionally installed on the existing elevator 2. it can. Needless to say, the car floor control device according to the present invention is applicable not only to an existing elevator but also to a new elevator.

  When the movable floor plate 45 of the movable car floor 42 is provided with a movable end portion 52 that can be tilted in the vertical direction and a movable floor expansion / contraction portion 46 that tilts the movable end portion 52 of the movable floor plate 45, While the door is open, it is possible to eliminate the step between the riding platform 4 and the landing 3 without moving the riding platform 4 itself of the elevator 2. Thereby, the safety | security of the elevator 2 can be improved more.

  Here, if the above-mentioned step is eliminated by tilting only the movable end 52 of the movable floor plate 45 instead of moving the entire movable floor plate 45 up and down, the power required for the operation can be reduced. Further, when only the movable end portion 52 of the movable floor plate 45 is inclined to eliminate the step, the elevator is provided with a load detection device that detects the load in the car based on the amount of sinking of the car floor 22 below the car floor 22. In, the influence on the load detection device can be reduced. That is, since the entire movable bottom plate 45 is not moved up and down in order to eliminate the step, the function of the load detection device can be maintained.

  The movable platen 47 is provided at the movable end 52 of the movable floor plate 45 and can move forward and backward along the direction toward the landing 3, and the movable plate 47 is positioned so as not to interfere with the riding door 24 when the riding door 24 is closed. When a movable plate control unit 48 is provided for moving the movable plate 47 forward toward the landing 3 when the riding door 24 is opened, the landing 3 and the movable floor plate 45 can be added by additionally installing the movable car floor 42. The gap generated between the two can be narrowed. This contributes to improvement in safety and comfort of the elevator 2.
