  As shown in FIG. 1A, the movable platform fence 1 includes a first door device 10 installed near the track side edge of the platform 30, and a rail direction of the first door device 10 (FIG. 1A). (Left-right direction) and a pair of both-side door devices 20 installed at predetermined intervals on both sides. The 1st door apparatus 10 and the both-side door apparatus 20 are act | operated according to the opening / closing operation | movement of the entrance / exit doors 33a and 34a which open / close the entrance / exit 33/34 of the train stopped in the platform 30. FIG. In this Embodiment, the both-sides door apparatus 20 is installed in the track | orbit side (FIG. 1 (a) back side of a paper surface) of the existing fixed fence 31 formed with the pipe material.

  The first door device 10 is supported by the first base 11 and the first base 11 erected on the platform 30 at a substantially equal distance from the fixed fences 31, 31 installed at intervals in the rail direction. And a first door body 13 arranged in parallel with the track. The first door 13 has a rail direction (FIG. 1 (a) left-right direction) length that is greater than the length of the first base 11 in the rail direction, and a distance S between adjacent entrances 33 and 34 of the train 32. It is set large. Further, since the first base 11 is disposed on the track side (the back side in FIG. 1A) with respect to the first door body 13, the first base body 11 is blocked by the first door body 13 and gets on and off the platform 30. It is possible to make the customer hardly see the first base 11 (only the root of the first base 11 can be seen).

  In the first door body 13, a plurality of through holes 13 a formed in a rectangular shape when viewed from the front pass through in the thickness direction and are provided on the upper side of the first door body 13. The first door body 13 can be reduced in weight by providing the through hole 13a. A transparent panel made of synthetic resin or glass is mounted in the through hole 13a.

The first door body 13 is formed on the back side of the platform 30 (right side in FIG. 2) with respect to the first base 11. ). Each hollow extruded shape member is disposed with the extrusion direction parallel to the opening / closing direction of the first door body 13 and with the extrusion width direction directed in the vertical direction. By forming the 1st door body 13 with a hollow extrusion shape material, weight reduction can be achieved, ensuring intensity | strength. Therefore, even if the dimension of the first door 13 in the rail direction is increased, the first door 13 can be supported on the first base 11 in a cantilevered state.

  In the first door 13, a plate-like support member 14 that protrudes toward the track side (left side in FIG. 2) is fixed to the side surface of the track side by welding or the like along the rail direction (vertical direction in FIG. 2). In the support member 14, the projecting first track member 15 is fastened and fixed to the lower surface by bolts along the rail direction (perpendicular to the plane of FIG. 2). The first track member 15 is a rod-like member engaged with the first guide member 12 and is formed of a steel material or the like so as to have a length substantially the same as the length of the first door body 13 in the rail direction. The first guide member 12 and the first track member 15 constitute a linear bearing, and the first track member 15 slides with respect to the first guide member 12.

  The first door 13 is provided with a flange 16 above the first track member 15 in the rail direction (perpendicular to FIG. 2). The eaves part 16 is comprised by the elongate thin plate-shaped member, the one end edge of a sleeper direction (FIG. 2 left-right direction) is fixed to the upper position from the 1st track member 15, and the other end edge of a sleeper direction is a 1st door. It protrudes from the body 13 to the track side (left side in FIG. 2). The collar portion 16 is disposed so as to be inclined downward from one edge in the sleeper direction toward the other edge. The other edge in the sleeper direction is tracked by the first guide member 12, the support member 14, and the first track member 15. It protrudes to the side. Since the collar portion 16 can block sunlight, rainwater, and the like over the rail direction of the first track member 15, the first track member 15 and the first guide member 12 can be protected from sunlight, rainwater, and the like. Moreover, since the upper surface of the collar part 16 is inclined downward toward the track side, rainwater or the like can flow down to the track side. As for the collar part 16, the back panel 17 is continuously provided in the other end edge at the track side toward the downward direction.

  As shown in FIG. 3, the back panel 17 is a plate-like member in which the length in the rail direction is set to be the same as the length in the rail direction of the flange portion 16 by arranging a plurality of the panels in the rail direction, and the upper end is supported. The member 14 (see FIG. 2) is fixed to the end surface on the track side and is disposed on the track side of the first base 11. Since the lower edge of the back panel 17 is located below the first guide member 12 and the first track member 15, the back panel 17 covers the back side (track side) of the first base 11 and The upper side, the first guide member 12 and the first track member 15 can be made invisible from the track side. Further, since the first guide member 12 and the first track member 15 are covered by the flange portion 16 and the back panel 17, foreign matter or the like is prevented from being caught in the sliding surfaces of the first guide member 12 and the first track member 15.

Therefore, it is not necessary to provide the platform 30 with guide rails for guiding the movement of the first door 13 and the both-side doors 23 in the rail direction, and guide rollers that require frequent maintenance are provided on the first door 13 and the both-side doors 23. It is no longer necessary to provide it at the bottom.

  Moreover, since the first door body 13 and the both side door bodies 23 are formed of a hollow extruded shape member having a high bending strength, even in a cantilever state, the external force due to contact of passengers and the wind pressure when passing through a high-speed train Can withstand. Furthermore, since it is not necessary to install a door pocket that accommodates the first door body 13 and the both door bodies 23, the movable home fence 1 can be reduced in weight, and the existing fixed fence 31 does not need to be removed. Since the movable platform fence 1 can be reduced in weight, the movable platform fence 1 can be installed without particularly reinforcing the platform even in the case of a platform having a work path and a retreat space provided in the lower part of the track.

  Moreover, since the 1st door body 13 and the both-side door body 23 are driven separately by the 1st drive device 18 (drive device) each arrange | positioned at the 1st base 11 and the base 21, respectively, the 1st door body 13 and both sides Control of the first door body 13 and the both-side door bodies 23 can be simplified as compared with the case where the power of the drive source is transmitted via a power transmission mechanism that interlocks the door bodies 23.

  Next, a second embodiment will be described with reference to FIGS. In 1st Embodiment, the rail direction length of the 1st door body 13 of the 1st door apparatus 10 is set larger than the space | interval S (refer Fig.1 (a)) of the entrance / exit 33,34 which the train 32 adjoins. Explained the case. On the other hand, 2nd Embodiment demonstrates the case where the rail direction length of the 1st door body 53 of the 1st door apparatus 50 is set smaller than the space | interval S of the adjacent entrance / exit 33,34. In addition, about the part same as the part demonstrated in 1st Embodiment, the same code | symbol is attached | subjected and the following description is abbreviate | omitted.

  FIG. 4A is a front view of the movable home fence 41 schematically showing a closed state of the movable home fence 41 in the second embodiment, and FIG. 4B is a state in which an opening is formed. 4C is a front view of the movable home fence 41 schematically showing, and FIG. 4C schematically shows the movable home fence 41 moved corresponding to the trains at different positions of the entrances 38 and 39. 3 is a front view of a movable home fence 41. FIG. 4 (a) to 4 (c), the train entrances 33, 34, 38, and 39 are shown, and the outer shape of the train is not shown (FIG. 6 (a) to FIG. Same in c)).

  As shown in FIG. 4A, the movable home fence 41 has two side door devices 20 and a first door device 50. The both-side door device 20 is disposed on the track side of the fixed fence 31 and includes both-side door bodies 23 configured to be able to enter the inside of the fixed fence 31 in the rail direction. The first door device 50 includes both-side door bodies 23 and 23. The 1st door body 53 provided in parallel by the rail direction between is provided. The length of the first door 53 in the rail direction is set to be smaller than the interval between the adjacent entrances 33 and 34 (see FIG. 4B). The platform 30 is provided with cameras 61 and 62 for imaging the roof near the movable platform fence 41 of the train stopped on the platform 30 and the outer plate of the side structure. The cameras 61 and 62 are installed at positions where a predetermined mark provided on the roof or outer plate of the train can be imaged. As the mark, for example, doors 33a and 43a (see FIG. 1 (a)), a car number sticker, a train front portion and a rear end portion, and the like that can specify the stop position of the train can be appropriately adopted.

  Next, a control device 60 that captures and processes images captured by the cameras 61 and 62 will be described with reference to FIG. FIG. 5 is a block diagram showing an electrical configuration of the movable home fence 41. The control device 60 is a device that detects the stop position of the train and drives and controls the doors 23 and the first door 53 based on the detection result.

  The control device 60 reads a signal including train formation information such as the number of trains and a formation number of a train that is input by wire from a train control system (not shown) or an input device (not shown) operated by a staff member. The train information acquisition means 63 for acquiring train formation information, and a mark when the train stops on the platform 30 (see FIG. 4A) as scheduled based on the train formation information acquired by the formation information acquisition means 63 The reference position calculating means 64 for calculating the reference position and the door control means 65 for controlling the driving of the first driving device 18 (driving device).

  The control device 60 further captures images captured by the cameras 61 and 62 and performs image processing to detect the mark, and the position of the mark detected by the image capturing means 66 and the reference position.

The door control means 65 moves the first drive device 18 (drive device) based on the reference position of the mark calculated by the reference position calculation means 64 and the deviation (distance) of the mark calculated by the error calculation means 67 with respect to the reference position. Drive control is performed, and the both-side door body 23 and the 1st door body 53 are moved to a predetermined position. Even when an abnormal stop such as a train overrun or a front stop occurs, the door control means 65 avoids the positions of the entrances 33 and 34 (see FIG. 4B) and the both-side door bodies 23 and the first door bodies 53. Therefore, it is possible to prevent the occurrence of problems such as passengers being unable to get on and off smoothly.

  Returning to FIG. 4, the operation of the movable home fence 41 will be described. As shown in FIG. 4 (a), when the train does not enter the platform 30, the movable platform fence 41 moves both the door bodies 23, 23 inward in the rail direction, thereby moving the both-side door bodies 23, 23 together. The first door body 53 is brought into contact with the first door body 53 and maintained in the closed state.

  As shown in FIG. 4B, when the train enters the platform 30 and stops, the doors 23 and 23 and the first door 53 move by the control device 60 according to the positions of the train entrances 33 and 34. In addition, an opening for getting on and off is formed in the movable platform fence 41. In the present embodiment, the first door 53 whose rail direction length is set to be smaller than the distance between the entrances 33 and 34 moves between the entrances 33 and 34, and the doors 23 and 23 on both sides are outside in the rail direction. The opening is formed on both sides of the first door 53 in the rail direction.

  As shown in FIG. 4 (c), when a train with different positions of the entrances 38 and 39 enters the platform 30 and stops due to train formation, the control device 60 causes the doors on both sides according to the positions of the train entrances 38 and 39. The bodies 23 and 23 and the first door body 53 move, and an opening for getting on and off is formed in the movable platform fence 41. In the present embodiment, both the door bodies 23 and 23 are moved outward in the rail direction, and the first door body 53 is moved to the right side in the rail direction (right side in FIG. 4C). An opening is formed on the left side in the rail direction.

  According to this movable platform fence 41, the length of the first door 53 in the rail direction is set to be shorter than the distance between the adjacent entrances 33 and 34 of the train entering the platform 30. Therefore, when an error occurs between the reference stop position of the train entering the platform 30 and the actual stop position, the first door body 53 is moved in accordance with the error, and the distance from the first door body 53 is increased. By opening the doors 23 and 23 on both sides, openings corresponding to the positions of the train entrances 33 and 34 can be provided on both sides of the first door 53. Therefore, the error between the reference stop position of the train and the actual stop position can be absorbed by the two side door bodies 23 and 23 and the first door body 53.

  Next, a third embodiment will be described with reference to FIG. In 1st Embodiment and 2nd Embodiment, the case where the 1st door bodies 13 and 53 were arranged in parallel between the both-side door bodies 23 and 23 was demonstrated. On the other hand, according to 3rd Embodiment, the case where the 1st door body 83 and the 2nd door body 93 are arranged in parallel between the both-side door bodies 23 and 23 is demonstrated. In addition, about the part same as 1st Embodiment, the same code | symbol is attached | subjected and the following description is abbreviate | omitted.

The rail direction length of the 1st door body 83 is set smaller than the space | interval of the entrance / exit 33 and 34 (refer FIG.6 (b)) which a train adjoins.

  The second door device 90 is the same as the first door device 10 except that the length of the second door body 93 in the rail direction (left and right direction in FIG. 6A) is set smaller than the length of the first door body 83 in the rail direction. It is configured identically. Therefore, about the same part as the 1st door apparatus 10, the same code | symbol is attached | subjected and the following description is abbreviate | omitted. The second track member, the collar portion, and the rear panel of the second door device 90 are configured in the same manner as each portion of the first door device 10, but the length in the rail direction is the length in the rail direction of the second door body 93. It is set according to the size.

  The second door body 93 is formed of a hollow extruded shape member made of an aluminum alloy. The length of the second door 93 in the rail direction is set to be smaller than the distance between the adjacent entrances 33 and 34 (see FIG. 6B), 38 and 39 (see FIG. 6C) of the train. The second base 91 of the second door device 90 is configured in the same manner as the first base 11 of the first door device 10 and has a predetermined interval in the rail direction with respect to the first base 11 and the base 21. And standing on the platform 30. By operating a second drive device (not shown) such as an electric motor disposed on the second base 91, the second door body 93 can be reciprocated with respect to the second base 91.

  As shown in FIG. 6 (a), the movable platform fence 71 has the first door 83 and the second door 93 abutted against each other and the both-side doors 23 and 23 when the train does not enter the platform 30. Are moved inward in the rail direction so that the doors 23, 23, the first door 83, and the second door 93 are brought into contact with each other and maintained in the closed state.

  As shown in FIG. 6B, when the train enters the platform 30 and stops, both doors 23 and 23, the first door 83, and the second door 93 according to the positions of the train entrances 33 and 34. And an opening for getting on and off is formed in the movable platform fence 71. In the present embodiment, the first door 83 whose rail direction length is set to be smaller than the distance between the entrances 33 and 34 moves between the entrances 33 and 34, and the both-side doors 23 and 23 and the second doors are moved. As 93 moves to the outside in the rail direction, openings are formed on both sides of the first door 83 in the rail direction.

  As shown in FIG. 6 (c), when a train with different positions of the entrances 38 and 39 enters the platform 30 and stops due to train formation, the doors 23 and 23 on both sides according to the positions of the entrances 38 and 39 of the train. The first door 83 and the second door 93 move, and an opening for getting on and off is formed in the movable home fence 71. In the present embodiment, both the door bodies 23 and 23 and the first door body 83 move outward in the rail direction, and the second door body 93 moves to the left side in the rail direction (left side in FIG. 6C). Openings are formed on both sides of the second door body 93 in the rail direction.

  According to this movable home fence 71, the rail direction length of the second door body 93 is set to be shorter than the rail direction length of the first door body 83, so the first door is between the entrances 33 and 34. From the distance between the entrance / exit 33, 34 when the body 83 is located and the end of the first door 83 in the rail direction, the entrance / exit 33, when the second door 93 is located between the entrance / exit 33, 34, The distance between 34 and the end of the second door 93 in the rail direction can be increased. As a result, the margin of the boarding / alighting opening formed by the second door body 93 can be made larger than the margin of the boarding / alighting opening formed by the first door body 83. Therefore, it is possible to make it difficult for passengers passing through the opening to feel a sense of pressure.

  Moreover, since the rail direction length of the 2nd door body 93 is set smaller than the space | interval of the adjacent entrance / exit 33,34,38,39 of a train, by providing the 2nd door body 93, the 2nd door A boarding opening can be provided on both sides of the body 93. Therefore, the degree of freedom for making the opening position variable can be improved.

  The present invention has been described above based on the embodiments. However, the present invention is not limited to the above embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. It can be easily guessed. The shape given in the above embodiment is an example, and other shapes can naturally be adopted. Further, the sizes of the first door bodies 13, 53, 83, the both-side door bodies 23, the second door bodies 93, the heights of the first base 11, the base 21, the second base 91, and the like are movable homes. It can be set as appropriate based on the mass and mechanical strength of the fences 1, 41, 71, the strength of the platform, the width of the entrance / exit, the wind pressure by the train passing through the platform, and the like.

  In each said embodiment, in the 1st door apparatus 10, 1 set of 1st track members 15 and 1st guide members 12 which guide the 1st door body 13 to the rail direction with respect to the 1st base 11 are arranged. Explained the case. However, the present invention is not necessarily limited to this, and it is a matter of course that a plurality of first track members 15 are arranged side by side and a plurality of first guide members 12 that respectively support the first track members 15 are slidable. Is possible. By providing a plurality of sets of the first track member 15 and the first guide member 12, it is possible to improve the support strength of the first door body 13 that is supported by the first base 11 in a cantilevered state. This is the same in the first door members 50 and 80, the second door member 90, and the both side door members 20.

  In each of the above embodiments, the first door bodies 13, 53, 83, the both-side door bodies 23, the second door body 93 formed of hollow extruded profiles, the support member 14, the flange portions 16, 26, and the rear panel 17, Although the case where 27 is fixed has been described, the present invention is not necessarily limited thereto, and the support member 14, the flanges 16, 26, and the rear panels 17, 27 are connected to the first door bodies 13, 53, 83, and the both door bodies 23.

Of course, it is possible to provide a door pocket in which the base 21 is installed and to allow the door body to appear in and out of the door pocket. The rail direction length of the door pocket can be made larger than the rail direction length of the door body. This is because even if a door pocket is installed on the track side of the fixed fence 31, it does not hinder passenger traffic. Of course, it is possible to omit the fixed fence 31 and dispose a double-sided door device that allows the door body to appear in and out of the door pocket. This is because the door pocket exerts the function of the fixed fence 31.

  Similarly, for the first door devices 10, 50, 80 and the second door device 90, it is naturally possible to provide a door pocket in which the base 21 is provided so that the door body can be moved in and out of the door bag. However, when providing a door pocket in the 1st door apparatus 10, 50, 80 or the 2nd door apparatus 90, the rail direction length of a door pocket is made smaller than the rail direction length of a door body. This is because if the length in the rail direction of the door pocket is larger than the length in the rail direction of the door body, the passage of passengers is hindered.

  Moreover, although each said embodiment demonstrated the case where the both-sides door apparatus 20 was installed in the track | orbit side of the fixed fence 31, the fixed fence 31 is not necessarily required. Of course, it is possible to install the movable platform fences 1, 41, 71 on the platform 30 where the fixed fence 31 is not installed.
