Therefore, in FIG. The upper side is the track side, and the lower side of the page is the home side.

This platform door 1 has an opening for getting on and off the wall surface 2 standing on the platform H so as to block between the track side on which the track vehicle travels and the platform H side used for getting on and off passengers. 3 and, further, to open and close the opening 3 serving as a boarding passage when getting on and off the track vehicle, the door 30 housed in the door pocket 10 is slid by a driving mechanism 70 such as an electric motor and a rack and pinion described later. It is configured as follows. In the illustrated home door 1, two door portions 30 that open and close adjacent left and right openings 3 are accommodated inside the door pocket 10 in a state where they are shifted and overlapped in the thickness direction of the door pocket.
The outer wall surface of the door pocket 10 having a substantially rectangular parallelepiped shape forms part of the wall surface 2 together with the door portion 30.

  In the closed state where the door 30 closes the opening 3 with the door 30, the wall surface 2 blocks the track side and the home H side, so that passengers fall on the track, It is possible to prevent the passengers from coming into contact with the track vehicle on which the vehicle travels, protect the passengers and ensure safety. In addition, the home door 1 is used as an entrance / exit passage for passengers getting on and off the track vehicle in the open state where the open portion 3 is opened by storing the door portion 30 in the door pocket 10. it can.

Now, the above-described home door 1 is configured to open and close the opening for getting on and off by sliding one door portion 30 in the opening / closing direction (door bag width direction) by the drive mechanism 70, that is, the door portion with respect to the door bag 10. In order to support 30 so that sliding is possible, the slide mechanism comprised by the slide support member and slide rail which are mentioned later is provided.
The slide mechanism of the present embodiment employs a linear guide slide mechanism (hereinafter referred to as “linear slide mechanism”) 50. The linear slide mechanism 50 includes a slide rail support member (not shown) fixedly supported on the door pocket 10 side and a slide rail 51 slidably supported by the slide rail support portion.

  The slide rail 51 is attached to the surface on the track side of the door portion 30 and extends over substantially the entire length in the door width in the opening / closing direction. Further, the linear slide mechanism 50 includes a rail cover 52 that is attached to the door 30 and covers the upper surface side and the track side of the slide rail 51 over the entire length. This rail cover 52 covers the components of the linear slide mechanism 50 coming out of the door pocket 10 in a state where the entrance 3 for getting on and off is closed, specifically, the components such as the slide rail 51 are not exposed. For example, a long member obtained by bending a plate material into a substantially L-shaped cross-sectional shape is used.

In this case, the electric motor 71 and the pinion gear 72 are disposed on the lower end portion side in the door pocket 10 and in the vicinity of the side end portion where the door portion 30 enters and exits. Such an arrangement is possible because the weight of the door portion 30 is supported by the linear guide slide mechanism 50 described above. As a result, the allowance of the door portion 30 that opens and closes together with the rack gear 73 can be ensured to the maximum. it can.
In addition, about the drive mechanism of the door part 30, it is not limited to the structure of the drive mechanism 70 mentioned above.

The home door 1 of the present embodiment opens and closes the opening / closing opening 3 by sliding the door 30 supported by the linear slide mechanism 50 by the operation of the drive mechanism 70 while being housed in the door pocket 10. . And the platform door 1 of this embodiment is the opening-and-closing direction width | variety of the door pocket 10 from the objective which can adjust the position of the opening part 3 etc. corresponding to a boarding / alighting exit position and boarding / alighting gate width which change with track vehicles, It is set to a value smaller than the opening / closing direction width of the door part 30.
For this reason, for example, as shown in FIGS. 1 to 5, the door pocket 10 has an opening state in which the opening portion 3 is opened, that is, the door portion 30 is accommodated in the door pocket 10 and can be loaded and unloaded. At the time of the opening operation, in order to allow the door butt side 31 of the door 30 protruding from the side wall surface of the door pocket 10 having a small opening and closing direction width to enter and exit, the door butt opening 11 is provided on the door butt side wall surface of the door pocket 10. ing.

  Further, a cover member 80 that allows the door 30 to enter and exit from the door butt opening 11 and is fully closed in a state where the end of the door butt side 31 of the door 30 is passed to the door pocket 10 side. Is provided. In the illustrated configuration example, in the two door portions 30 arranged on the track side and the home side, the door bottom opening portion 11 for entering and exiting the door bottom side 31 of the door portion 30 arranged on the track side is provided. A cover member 80 is provided.

Such a cover member 80 can close the door opening 11 when the door opening 31 is closed and the end of the door edge 31 does not protrude from the door opening 11. Even if the opening part 3 for getting on and off is opened and the end part of the door butt side 31 protrudes from the door butt opening part 11, entry / exit of the door butt side 31 is not hindered.
In addition, the cover member 80 is not provided in the door-end opening portion 12 that allows the door-end side 32 of the door portion 30 disposed on the home side to enter and exit, and the door-end opening portion 12 corresponds to the door portion 30. It is blocked by a tip portion that becomes the door end side 32.

  The door bottom side opening 11 provided with the cover member 80 described above has a shape that can pass through the constituent members of the linear slide mechanism 50 that moves integrally with the door 30. Therefore, as shown in FIG. 2, for example, the door bottom side opening 11 shown in FIG. 2 includes a door portion opening portion 11a having an elongated substantially rectangular cross section through which the door portion 30 passes, and upper and lower ends of the door portion opening portion 11a. The slide mechanism openings 11b and 11c having a substantially rectangular cross-sectional shape through which the constituent members of the linear slide mechanism 50 provided in two places in communication with the vicinity of the section pass.

The cover member 80 installed in the door-side opening 11 is divided into a door-side cover member 81 and a rail-cover-side cover member (hereinafter referred to as “rail-side cover member”) 82. It has become.
The door-side cover member 81 is a door type in which an elongated plate-like member is swingably supported by a hinge 83 biased in the closing direction. In the illustrated configuration example, four hinges 83 arranged in the vertical direction are used, but there is no particular limitation.

  That is, the door portion side cover member 81 of the present embodiment is an elongated substantially rectangular plate-like member that substantially coincides with the door opening portion 11a, and the door portion side cover member 81 extends from the door portion opening portion 11a. By swinging so as to be pushed out to the door butt side 31 of the protruding door part 30, the door part opening part 11a is pushed open without hindering the door part 30 from entering and exiting as indicated by a solid line in FIG. . And when the door bottom side 31 of the door part 30 is accommodated in the door pocket 10, since the hinge 83 has received the urging | biasing of the closing direction, as shown in an imaginary line in FIG. 81 swings automatically and closes the door opening 11a.

The rail side cover member 82 is a slide type that moves in the opening / closing direction of the door portion 30 in conjunction with the rail cover 52.
That is, the rail-side cover member 82 of the present embodiment has two surfaces on the door 30 side and two sides on the door pocket 10 side from a rectangular parallelepiped box-shaped member whose tip end surface 82a has substantially the same shape as the slide mechanism openings 11b and 11c. And is supported so as to be slidable in the opening and closing direction along a guide rail 84 attached to an appropriate inner wall surface of the door pocket 10. Further, a magnet 85 is fixedly installed on the door pocket side wall surface of the distal end surface 82a as a holding mechanism that is connected to an appropriate position on the door bottom side of the door portion 30.

The rail-side cover member 82 configured in this manner is pushed out to the door-end side end of the rail cover 52 that moves in the opening / closing direction integrally with the door portion 30, so that it is displayed as a solid line in FIGS. 4 and 5. The sliding mechanism openings 11b and 11c are pushed open without hindering the door 30 from entering and exiting. At this time, the door 30 is connected to the tip end surface 82 a of the rail side cover member 82 by the magnetic force of the magnet 85.
And when the door bottom side 31 of the door part 30 moves in the direction accommodated in the door pocket 10, the rail side cover member 82 will also slide with the door part 30 connected with magnetic force, Therefore FIG.4 and FIG.5 shows an imaginary line. As shown by, the slide mechanism openings 11b and 11c can be closed.

  Further, when the rail side cover member 82 slides to a predetermined fully closed position, further movement is prevented by, for example, the stopper 86, so that the connection by the magnet 85 is released. As a result, the rail side cover member 82 is left in a predetermined fully closed position, and thereafter, only the door portion 30 moves alone.

By the way, the rail side cover member 82 may be provided with a holding mechanism for reliably maintaining the fully closed state at the fully closed positions of the slide mechanism openings 11b and 11c constituting the door butt opening 11. desirable. As this holding mechanism, for example, a magnet 87 may be attached to the vicinity of the end portion inside the door pocket by the rail side cover member 82 and connected to the stopper 86 by magnetic force. Such connection by the magnet 87 is released when the above-described rail-side cover 82 starts an opening operation.
In the above-described embodiment, the magnets 85 and 87 are used as the holding mechanism that maintains the connected state until a predetermined force is received. However, for example, a catch clip or the like may be employed.

  Moreover, the rail side cover member 82 described above is pushed out to the door bottom side end portion of the rail cover 52 that moves in the opening and closing direction integrally with the door portion 30 to open the slide mechanism openings 11b and 11c, and is connected by magnetic force. The opening / closing mechanism that slides the rail-side cover member 82 together with the door 30 and closes the sliding mechanism openings 11b and 11c is employed. However, a modification of the opening / closing mechanism described below may be employed.

In the modification of the opening / closing mechanism shown in FIG. 6, a compression spring 91 is employed for opening / closing (sliding) the rail-side cover member 82. Also in this modified example, the rail-side cover member 82 is a slide type that moves in the opening / closing direction of the door portion 30 in conjunction with the rail cover 52 in the same manner as shown in FIG. Is supported so as to be slidable in the opening / closing direction along a guide rail 84 attached thereto.
The compression spring 91 is, for example, a coil spring interposed in the sliding direction of the guide rail 84, and always applies a biasing force in the closing direction to the rail side cover member 82. The compression spring 91 is further compressed to increase the biasing force in the closing direction by moving the rail side cover member 82 by the stroke L in the drawing from the fully closed position indicated by the imaginary line to the fully open position indicated by the solid line. .

  That is, the rail side cover member 82 is pushed out by a stopper 92 attached to an appropriate position on the door bottom side 31 of the door portion 30, thereby opening the slide mechanism openings 11 b and 11 c and increasing the compression amount of the compression spring 91. . Further, when the door butt side 31 of the door portion 30 moves in the direction in which it is housed in the door pocket 10, the rail side cover member 82 is closed and held in the fully closed position by the urging force of the compressed compression spring 91. .

  In the cover member 80 configured as described above, the door-side cover member 81 and the rail-side cover member 82 both independently open and close the door opening 11a and the slide mechanism openings 11b and 11c at the same time. For example, as in the first and second modifications described below, the door opening 11a and the slide mechanism openings 11b and 11c may be opened and closed with a single cover member.

In the first modification shown in FIG. 7, the sliding cover member 80A opens and closes the door opening 11a and the sliding mechanism openings 11b and 11c. Although the cover member 80A is different in shape from the rail-side cover member 82 described above, the basic opening / closing operation structure is the same.
That is, in this modified example, the door-type door portion side cover member 81 described above is eliminated, and the door portion opening portion 11a and the sliding mechanism opening portions 11b and 11c are opened and closed only by the slide type cover member 80A. Is.
In addition, the solid line display in a figure is the state which opened the door butt opening part 11, and the imaginary line display in a figure will be in the state which closed the door butt opening part 11. FIG.

  The second modification shown in FIG. 8 employs a take-up reel type cover member 80B. The cover member 80B has a structure in which the sheet-like screen 88 is wound around a take-up roll 89 with a spring, is pushed out by the door 30 and the rail cover 52, and is unwound by a spring force in the take-up roll 89. It has become.

  That is, the sheet-like screen 88 changes its unwinding amount in conjunction with the movement of the door portion 30 and the rail cover 52 in the opening / closing direction, and the sheet-like screen 88 is most rewound as shown in FIG. Thus, the door butt opening 11 is fully closed. Further, FIG. 8B shows a state in which the sheet-like screen 88 is unwound from the fully closed state, and the door opening 11 is gradually opened. Reference numeral 90 in the figure denotes a guide roller that makes the sheet-like screen 88 move smoothly.

  As described above, according to the above-described home door 1 of the present embodiment, the cover members 80, 80 </ b> A, 80 </ b> B allow the door butt side 31 of the door 30 to enter and exit from the door pocket 10, while opening the door butt. 11 is closed, so that foreign matter such as dust can be prevented from entering the door pocket 10 from the door opening 11, and passengers can be opened and closed inside the door bag 10 from the door opening 11.
