  If the information presentation device is attached at a position where the maintenance opening is not blocked as in the invention described in Patent Document 3, the maintenance work of the equipment in the door pocket becomes easy. However, such arrangement is possible only when a relatively small information presentation device is used. For example, when a large information presentation device described in Patent Document 1 is attached to a door pocket, it is difficult to arrange the information presentation device so as not to block the maintenance opening.

  In particular, recently, in order to improve visibility, it is required to attach a large information presentation device to a door pocket. Therefore, there is a problem that it is difficult to arrange a maintenance opening of an appropriate size at an appropriate position. As a result, there is a problem that the maintenance work of the equipment in the door pocket becomes troublesome. Of course, if the information presentation device is removed from the door pocket every time maintenance work is performed, there are no restrictions on the arrangement and size of the maintenance opening, but the maintenance work including the attachment / detachment work of the information presentation device becomes complicated. There is no change.

  This invention is made in order to solve the above-mentioned problem, and provides a home door apparatus which can attach a large sized information presentation apparatus to a door pocket, and the maintenance of the apparatus in a door pocket is easy. With the goal.

  In order to achieve the above object, a home door apparatus according to the present invention includes a fixed door pocket, a door body attached to the door pocket so as to freely move forward and backward, and is attached to the door pocket to access equipment in the door pocket and An access door panel that opens and closes a maintenance opening for performing maintenance on the device, and an information presentation device that visually presents information and presents the information, and the information presentation device is fixed to the access door panel.

  In the platform door device according to the present invention, since the information presentation device is fixed to the access door panel, the access door panel and the information presentation device do not interfere with each other on the side surface of the door body. Therefore, even if the information presentation device is enlarged, the position and size of the maintenance opening are not restricted. Moreover, when performing maintenance of the equipment in the door pocket, there is no need to remove the information presentation device from the door pocket. As a result, maintenance of the equipment in the door pocket becomes easy.

(First embodiment)
Fig.1 (a)-FIG.1 (c) are side views of the platform door apparatus 1 which concerns on 1st Embodiment of this invention. As shown in FIGS. 1 (a) to 1 (c), a platform door device 1 includes a door pocket 3 fixed to a floor 2 of a station platform and a door pocket 3 slidably attached to the door pocket 3. An access door panel 4 that covers the side surface, and a door body 5 that is attached to the door pocket 3 so as to freely advance and retract are provided. An information presentation device 6 is fixed to the access door panel 4. In this specification, as shown in FIGS. 1A to 1C, the X axis is set in the horizontal direction and the Y axis is set in the vertical direction, and this coordinate axis is referred to as appropriate. .

  FIG. 1A shows a state in which the door body 5 moves in the −X direction and is pulled out of the door pocket 3, that is, a state in which the entrance / exit passage is completely closed on the platform (fully closed state). ing. FIG. 1B shows a state in which the door body 5 moves in the + X direction and is drawn into the door pocket 3, that is, a state in which the entrance / exit passage is completely opened on the platform (fully opened state). FIG. 1C shows a state in which the access door panel 4 is slid in the + X direction and the side surface of the door pocket 3 is opened in the fully opened state.

  As shown in FIGS. 1A to 1C, the door pocket 3 includes a lower frame 31, a support column 32, and an upper frame 33. The lower frame 31 is a structural member that is directly fixed to the floor surface 2. The support column 32 is a structural member erected on the left and right ends of the lower frame 31. In FIG. 1A and FIG. 1B, since the access door panel 4 is in front of the support 32, the support 32 is not visible. Also in FIG. 1C, the support column 32 erected at the right end of the lower frame 31 is behind the access door panel 4 and cannot be seen. The upper frame 33 is a structural member disposed on the upper portion of the door pocket 3 and is supported at both ends by the support column 32.

  The access door panel 4 is supported by the lower frame 31 and the upper frame 33 so as to be slidable in the X-axis direction, and slides in the X-axis direction with respect to the door pocket 3. In a normal operation state, the side of the door pocket 3 is covered at a position as shown in FIGS. 1 (a) and 1 (b). When performing maintenance and inspection of the devices arranged inside the door pocket 3, as shown in FIG. 1C, the access door panel 4 is slid to the right side (+ X side) of the figure with respect to the door pocket 3. . As a result, the side surface of the door pocket 3 is opened, and access to the device arranged inside the door pocket 3 becomes possible. That is, the opening generated by sliding the access door panel 4 to the right side (+ X side) in the figure functions as a maintenance opening that accesses the device of the door pocket 3 and performs maintenance on the device. The access door panel 4 functions as a door or lid that opens and closes the maintenance opening. The access door panel 4 is slid by the operator's human power.

  As shown in FIG. 1C, a plurality of upper guide rollers 41a are pivotally supported on the upper side of the access door panel 4, and a plurality of lower guide rollers 41b are pivotally supported on the lower side. An auxiliary leg 42 is attached to the right (+ X side) end of the lower side of the access door panel 4. These actions will be described later.

  The information presentation device 6 is a device that is controlled by a control device (not shown), such as a liquid crystal display device, to display characters and images, that is, a device that presents information by appealing to the sight of passengers. In FIG. 1A to FIG. 1C, the screen portion on which characters and images of the information presentation device 6 are displayed is shaded. Thus, the information presentation device 6 is a large device that covers most of the surface of the access door panel 4 with the screen.

  In addition, the control apparatus which controls the information presentation apparatus 6 is arrange | positioned in the door pocket 3, and this control apparatus and the information presentation apparatus 6 are connected by the signal cable which is not shown in figure. The signal cable has a sufficient length and is supported so as to be able to move in accordance with the slide of the access door panel 4.

  Now, with reference to FIG.1 (c), the apparatus arrange | positioned inside the door pocket 3 is demonstrated. As shown in FIG. 1C, the upper guide rail 34 is fixed to the lower surface of the upper frame 33, and the lower guide rail 35 is fixed to the upper surface of the lower frame 31. The upper guide rail 34 and the lower guide rail 35 are rails that support the door body 5 and move it in the X-axis direction. An auxiliary roller 36 is pivotally supported on the upper surface of the lower frame 31 on the left side (−X side) from the left end portion of the lower guide rail 35. The auxiliary roller 36 is a roller that contacts the lower side of the door body 5 and supports the door body 5 so as to be movable in the X-axis direction.

  An upper roller 51 is pivotally supported on the upper side of the door body 5, and a lower roller 52 is pivotally supported on the lower side. The upper roller 51 is in contact with the upper guide rail 34 and the lower roller 52 is in contact with the lower guide rail 35, and rolls in the X-axis direction. Thus, the door 5 is supported by the upper guide rail 34, the lower guide rail 35, and the auxiliary roller 36, and can move freely in the X-axis direction.

  Further, inside the door pocket 3, a drive mechanism 7 that moves the door body 5 forward and backward with respect to the door pocket 3 is provided. As shown in FIG. 1C, the drive mechanism 7 includes a drive pulley 71, a driven pulley 72, and a timing belt 73. The driving pulley 71 and the driven pulley 72 are arranged with a gap in the X-axis direction, and are respectively supported by the door pocket 3. The drive pulley 71 is rotationally driven by a drive motor (not shown). The timing belt 73 is an infinite belt that is looped between the driving pulley 71 and the driven pulley 72 and circulates between the driving pulley 71 and the driven pulley 72. The timing belt 73 is connected to the door body 5 via a belt clamp 74. The belt clamp 74 is a component that connects the timing belt 73 and the door body 5, one end of which is clamped to the timing belt 73 and the other end is fixed to the door body 5.

  Since the drive mechanism 7 is configured as described above, the timing belt 73 circulates between the drive pulley 71 and the driven pulley 72 when the drive pulley 71 is rotationally driven by a drive motor (not shown). When the timing belt 73 circulates between the driving pulley 71 and the driven pulley 72, the belt clamp 74 advances and retreats between the driving pulley 71 and the driven pulley 72. When the driving pulley 71 is rotated counterclockwise, that is, in the direction of the arrow CCW in FIG. 1C, the timing belt 73 rotates counterclockwise. The belt clamp 74 moves in the direction indicated by the arrow FWD, that is, in the −X direction. As a result, the door body 5 moves in the −X direction and is pulled out of the door pocket 3. When the drive pulley 71 is rotated in the reverse direction, that is, clockwise, the door body 5 moves to the right side (+ X side) in FIG.

  Inside the door pocket 3, the above devices are built. As described above, when the access door panel 4 is slid in the + X direction with respect to the door pocket 3 in the state shown in FIG. 1B, the maintenance opening is opened. That is, the state shown in FIG. In this state, access to these devices becomes possible.

  Further, since the information presentation device 6 is fixed to the access door panel 4, when the access door panel 4 is slid to the + X side, the information presentation device 6 is also separated from the position covering the side surface of the door pocket 3. Therefore, in the state shown in FIG. 1C, the information presentation device 6 does not interfere with the maintenance work. When the access door panel 4 is moved to the −X side and returned to the original position after the maintenance work is completed, the information presentation device 6 also returns to the original position.

  Next, the detailed configuration and operation of the access door panel 4 will be described with reference to FIGS. As shown in FIG. 2, an upper guide groove 33a is formed on the lower surface of the upper frame 33, and a lower guide groove 31a is formed on the upper surface of the lower frame 31, both extending in the X-axis direction. . The upper guide roller 41a is pivotally supported on the access door panel 4 so as to be rotatable about the rotation axis R1, and is configured to contact the top surface of the upper guide groove 33a. Therefore, the upper guide roller 41a is guided by the upper guide groove 33a and rolls in the X-axis direction. The lower guide roller 41b is pivotally supported by the access door panel 4 so as to be rotatable about the rotation axis R2, and is configured to contact the bottom surface of the lower guide groove 31a. Therefore, the lower guide roller 41b is guided by the lower guide groove 31a and rolls in the X-axis direction. With this configuration, the access door panel 4 moves along the upper guide groove 33a and the lower guide groove 31a, that is, in the X-axis direction.

  As described above, the auxiliary leg 42 is attached to the right (+ X side) end of the lower side of the access door panel 4. As shown in FIG. 3, the auxiliary leg 42 is attached to the access door panel 4 so as to be swingable about the axis R3. The auxiliary leg 42 is pulled out and used as necessary, and is locked by a locking means (not shown). Is fixed at a position indicated by a solid line.
