Description

[Technical field]

[0001] The present invention relates to a platform structure. [Background technology]

[0002] An example of a conventional platform structure is disclosed in Patent Document 1. As shown in Fig. 1 and Fig. 4, this platform structure includes a platform, a plurality of gate posts, a drive unit, a control unit, a first left bar, a second left bar, a first right bar, and a second right bar.

[0003] The platform has an edge extending laterally, and a track car having multiple entrances stops or passes in front of the edge of the platform.

[0004] The gate posts are spaced apart from one another along the edge of the platform and extend vertically upward. A drive unit is built into each gate post to generate a drive force. A control unit controls each drive unit.

[0005] Each gate post has a plurality of left gate posts provided with a first left bar and a second left bar, and a plurality of right gate posts provided with a first right bar and a second right bar. The first left bar and the second left bar are rod-shaped and provided on each left gate post. The first right bar and the second right bar are rod-shaped and provided on each right gate post.

[0006] The first left bar, the second left bar, the first right bar and the second right bar are supported so as to be swingable between an open position and a closed position by a driving force controlled by a control unit. The first left bar and the second left bar protrude leftward from the left gate post in the closed position. The first right bar and the second right bar protrude rightward from the right gate post in the closed position.

[0007] Each entrance of the rail car is provided with a left door and a right door. The left door slides from the left end position to the center position. The right door slides from the right end position to the center position. The left door and the right door have the same length in the left-right direction.

[0008] In this platform structure, when a rail car stops at a predetermined position in the left-right direction in front of the edge of the platform, the first left bar, the second left bar, the first right bar, and the second right bar extend in the vertical direction in the open position to allow people to disembark from each boarding / alighting door onto the platform and to board from the platform into each boarding / alighting door. When a rail car passes in front of the edge of the platform in the left-right direction, the first left bar, the second left bar, the first right bar, and the second right bar extend in the left-right direction in the closed position to prohibit disembarking and boarding. In this way, this platform structure allows passengers to disembark and board rail cars with multiple boarding / alighting doors with different arrangements and numbers while ensuring the safety of people on the platform.

[0009] [Patent Document 1] JP 2003-118567 A Summary of the Invention [Problem to be solved by the invention]

[0010] However, in the conventional platform structure, there are multiple obstacles that are fixed between two adjacent gateposts and extend in the left-right direction to prohibit passengers from getting on and off. Therefore, the rail car must stop in front of the edge of the platform so that each boarding / alighting entrance does not overlap with the gateposts and obstacles in the front-rear direction perpendicular to the left-right and up-down directions. This makes it difficult to operate the rail car.

[0011] Furthermore, the platform structure is required to have a simple configuration in order to reduce equipment costs such as installation and maintenance costs.

[0012] The present invention has been made in consideration of the above-mentioned conventional situation, and has as its object to provide a platform structure that makes it easy to operate track vehicles, ensures the safety of people on the platform, and is of a simple configuration, enabling smooth boarding and disembarking of passengers for track vehicles having multiple boarding and alighting doors with different arrangements and numbers. [Means for solving the problem]

[0013] The platform structure of the present invention includes a platform having an edge portion extending in a left-right direction, and a track vehicle having a plurality of boarding and alighting entrances stops in front of or passes through the edge portion; a plurality of equally spaced vertically upwardly extending gate posts on the platform along the edge; A driving unit is built into each of the gateposts and generates a driving force; A control unit that controls each of the drive units; a first left bar, a second left bar, a first right bar, and a second right bar each having a rod shape, each of which is provided on each of the gateposts, and each of which is supported so as to be swingable between an open position and a closed position by the driving force controlled by the control unit, the first left bar, the second left bar, the first right bar, and the second right bar each extending in a vertical direction at the open position to permit people to disembark from each of the boarding / alighting openings onto the platform and to board people from the platform into each of the boarding / alighting openings at the closed position, and extending in a horizontal direction to prohibit the disembarking and the boarding; Equipped with The first left bar and the second left bar protrude leftward from the gate post in the closed position, and the first right bar and the second right bar protrude rightward from the gate post in the closed position, Each of the boarding / alighting doors is provided with a left door that slides from a left end position to a center position, and a right door that slides from a right end position to the center position, the right door having a length in the left-right direction equal to that of the left door, The platform is not provided with any obstacles that are fixed between the two adjacent gateposts in a state of extending in the left-right direction and that prohibit the disembarking and the boarding of the passengers; The direction perpendicular to the left-right direction and the up-down direction is the front-back direction, The inner width in the left-right direction at each of the boarding and alighting doors is 2L, The outer width of each gatepost in the left-right direction is p, The interval between each of the gateposts in the left-right direction is 2x, The distance between each gatepost and the edge in the front-rear direction is defined as y, In the set of the first left bar, the second left bar, the first right bar and the second right bar supported by each of the gate posts, the outer width in the left-right direction in the open position is w, It is characterized in that 2L≦2x, L≦y, L>p, and w≦p are satisfied.

[0014] In the platform structure of the present invention, the platform is not provided with any obstacles that are fixed between two adjacent gateposts and extend in the left-right direction to prohibit boarding and disembarking. This platform structure satisfies 2L≦2x. As a result, when multiple types of rail vehicles with different arrangements and numbers of boarding and alighting doors stop in front of the edge of the platform, a part of each boarding and alighting door overlaps a part of each gatepost in the front-rear direction, while the other part of each boarding and alighting door does not overlap with each gatepost in the front-rear direction.

[0015] This platform structure satisfies L≦y, L>p, and w≦p. As a result, when the first left bar, second left bar, first right bar, and second right bar swing to the open position and passengers start getting on and off at each entrance, passengers getting on and off at an entrance that overlaps with a gate post in the front-to-rear direction can pass by the side of the overlapping gate post without making a large detour. Also, at that time, passengers getting on and off at an entrance that does not overlap with a gate post in the front-to-rear direction do not need to go around the gate post that does not overlap.

[0016] Therefore, even if the rail car stops with each boarding / alighting door overlapping with each gatepost in the front-rear direction, passengers can board and disembark without any problems. This makes it easy to operate the rail car.

[0017] Furthermore, this platform structure can be achieved by simply lining up a plurality of sets of gate posts, a first left bar, a second left bar, a first right bar and a second right bar on the platform along the edge.

[0018] Therefore, the platform structure of the present invention makes it easy to operate track vehicles, ensures the safety of people on the platform, and, with a simple configuration, enables smooth boarding and disembarking of passengers for track vehicles having multiple boarding and alighting doors with different arrangements and numbers.

[0019] Furthermore, according to this platform structure, even if a set of a gatepost, a first left bar, a second left bar, a first right bar, and a second right bar fails and the first left bar, the second left bar, the first right bar, and the second right bar of that set cannot swing to the open position, L≦y is satisfied, and passengers can easily bypass the first left bar, the second left bar, the first right bar, and the second right bar of the failed set by the set of a gatepost, the first left bar, the second left bar, the first right bar, and the second right bar next to the failed set. As a result, this platform structure can suppress the occurrence of confusion on the platform due to partial failure. Furthermore, according to this platform structure, waterproofing and dustproofing measures need only be taken for the parts supporting the swing shafts of the first left bar, the second left bar, the first right bar, and the second right bar of each gatepost. As a result, this platform structure can realize simplified maintenance work compared to a sliding door, etc., and can suppress a decrease in durability even if it is set in a place where it is likely to be exposed to rain, etc. In addition, according to this platform structure, since the width of the gatepost is narrowed by satisfying L>p, the gatepost is less susceptible to wind pressure caused by the passage of track vehicles, and further, since the gatepost is separated from the edge of the platform by satisfying L≦y, the gatepost is even less susceptible to wind pressure caused by the passage of track vehicles. As a result, the durability of the portion fastening the gatepost to the platform is improved. Furthermore, according to this platform structure, since w≦p is satisfied, the widths of the first left bar, the second left bar, the first right bar, and the second right bar are narrowed. Therefore, the first left bar, the second left bar, the first right bar, and the second right bar are less susceptible to wind pressure caused by the passage of track vehicles when they are swung to the closed position. As a result, this platform structure can simplify or omit platform reinforcement work, and ultimately reduce installation costs.

[0020] It is preferable that the first left bar, the second left bar, the first right bar and the second right bar have the same length. It is preferable that the first left bar can be swung around the first left axis, the second left bar can be swung around the second left axis, the first right bar can be swung around the first right axis and the second right bar can be swung around the second right axis. It is preferable that the first left axis, the second left axis, the first right axis and the second right axis extend in the front-rear direction. It is preferable that the second left axis is separated vertically downward from the first left axis and the second right axis is separated vertically downward from the first right axis. It is also preferable that the first left axis and the first right axis are the same height, and the second left axis and the second right axis are the same height.

[0021] In the conventional platform structure, as shown in FIG. 1 of Patent Document 1, the adjacent left and right gate posts are separate, the right side wall of the left gate post is adjacent to the left side wall of the right gate post, and each pair of left and right gate posts has two built-in drive units. In contrast, in this platform structure, one gate post does not have the right side wall of the left gate post and the left side wall of the right gate post in the conventional platform structure, and only has one built-in drive unit. As a result, this platform structure makes it easier to reduce the outer width in the left and right direction of each gate post compared to the outer width in the left and right direction of the adjacent left and right gate posts in the conventional platform structure. In addition, in the conventional platform structure, the second left axis is located at a position spaced downward and to the left from the first left axis, and the second right axis is located at a position spaced downward and to the right from the first right axis. In contrast, in this platform structure, the second left axis is located at a position spaced vertically downward from the first left axis and is not spaced to the left from the first left axis. In addition, the second right axle center is located vertically downwardly away from the first right axle center and is not located to the right of the first right axle center. This makes it easier to further reduce the outer width of each gate post in the left-right direction compared to the outer width of the adjacent left and right gate posts in the conventional platform structure. Therefore, this platform structure makes it easier to reduce the degree to which passengers getting off or on at a boarding / alighting entrance that overlaps with a gate post in the front-rear direction have to detour when passing by the overlapping gate post. As a result, this platform structure can further facilitate passengers getting off and on at rail cars with multiple boarding / alighting entrances with different arrangements and numbers.

[0022] The first left bar, the second left bar, the first right bar, and the second right bar are preferably located in one of the front and rear directions with respect to the gatepost and extend downward in the open position. The first left bar is preferably composed of a first left base portion extending in a long shape, a first left bent portion connected to the first left base portion and bent away from the gatepost, and a first left end portion connected to the first left bent portion and extending in a long shape in the same direction as the first left base portion. The second left bar is preferably located between the first left end portion and the gatepost in the open position. The first right bar is preferably composed of a first right base portion extending in a long shape, a first right bent portion connected to the first right base portion and bent away from the gatepost, and a first right end portion connected to the first right bent portion and extending in a long shape in the same direction as the first right base portion. And the second right bar is preferably located between the first right end portion and the gatepost in the open position.

[0023] In this case, the first left bar, second left bar, first right bar, and second right bar that extend downward in the open position are less likely to impair visibility of the platform compared to a case in which the first left bar, second left bar, first right bar, and second right bar extend upward in the open position. Also, the first left bent portion of the first left bar and the first right bent portion of the first right bar can prevent the first left base portion of the first left bar and the first right base portion of the first right bar from becoming bulky in the front-rear direction when the first left bar, second left bar, first right bar, and second right bar are in the open position.

[0024] The platform structure of the present invention preferably further comprises a third left bar that can be swung around a third left axis and has a length equal to that of the first left bar, the second left bar, the first right bar and the second right bar, and a third right bar that can be swung around a third right axis and has a length equal to that of the third left bar. The third left bar preferably swung between an open position extending vertically along the gatepost and a closed position protruding leftward from the gatepost by a driving force controlled by the control unit. The third right bar preferably swung between an open position extending vertically along the gatepost and a closed position protruding rightward from the gatepost by a driving force controlled by the control unit. The third left axis and the third right axis preferably extend in the front-rear direction. The third left axis is preferably located between the first left axis and the second left axis in the vertical direction. The third right axis is preferably located between the first right axis and the second right axis in the vertical direction. It is preferable that the third left axis and the third right axis are at the same height.

[0025] In this case, the first left bar and first right bar in the closed position, the second left bar and second right bar in the closed position, and the third left bar and third right bar in the closed position can reduce the vertical gap between them. As a result, this platform structure can reliably prohibit passengers from getting on and off at each boarding / alighting door when the first left bar, second left bar, third left bar, first right bar, second right bar, and third right bar are in the closed position.

[0026] The first left bar, the third left bar, the first right bar, and the third right bar are preferably located in one of the front and rear directions with respect to the gatepost and extend downward in the open position. The first left bar is preferably composed of a first left base portion extending in a long shape, a first left bent portion connected to the first left base portion and bent away from the gatepost, and a first left end portion connected to the first left bent portion and extending in a long shape in the same direction as the first left base portion. The third left bar is preferably located between the first left end portion and the gatepost in the open position. The first right bar is preferably composed of a first right base portion extending in a long shape, a first right bent portion connected to the first right base portion and bent away from the gatepost, and a first right end portion connected to the first right bent portion and extending in a long shape in the same direction as the first right base portion. The third right bar is preferably located between the first right end portion and the gatepost in the open position. It is desirable that the second left bar and the second right bar are positioned on the other side of the gate post in the front-to-rear direction and extend upward in the open position.

[0027] In this case, the first left bar, the third left bar, the first right bar, and the third right bar that extend downward in the open position are less likely to impair visibility of the platform compared to the case in which the first left bar, the third left bar, the first right bar, and the third right bar extend upward in the open position. In addition, the first left bent portion of the first left bar and the first right bent portion of the first right bar can prevent the first left base portion of the first left bar and the first right base portion of the first right bar from becoming bulky in the front-rear direction when the first left bar, the third left bar, the first right bar, and the third right bar are in the open position. Furthermore, even if the second left bar and the second right bar that extend upward in the open position are made longer, they are less likely to impair visibility of the platform.

[0028] It is preferable that the gate post has a base part to be installed on the platform, and a main body part to be fitted with the base part and fastened to the base part. It is preferable that the main body part swingably supports the first left bar, the second left bar, the first right bar, and the second right bar, or swingably supports the first left bar, the second left bar, the third left bar, the first right bar, the second right bar, and the third right bar.

[0029] In this case, since the main body can be easily attached and detached to the base, the replacement work of the main body can be simplified, and the time and cost can be reduced.

[0030] The base part is fastened to the platform and desirably includes a base plate having a plurality of screw holes in the center, a mounting plate having a plurality of upper through-holes in the center that align with the respective screw holes, a fitting part that is cylindrically shaped surrounding the respective upper through-holes and protrudes upward from the upper surface of the mounting plate and fits with the main body part to fasten the main body part, an intermediate plate having a middle through-hole in the center and sandwiched between the base plate and the mounting plate, and a plurality of bolts that are inserted from above into the respective upper through-holes and middle through-holes and screwed into the respective screw holes to fasten the mounting plate and the intermediate plate to the base plate. The upper surface of the intermediate plate and the lower surface of the mounting plate are desirably inclined with respect to the horizontal plane.

[0031] In this case, the intermediate plate can be easily adjusted to eliminate the inclination of the fitting portion relative to the vertical direction by rotating the intermediate plate relative to the mounting plate while the mounting plate and intermediate plate are temporarily fixed to the base plate with multiple bolts. As a result, the main body is less likely to incline relative to the vertical direction when fastened to the fitting portion. In addition, the intermediate plate and mounting plate cover the multiple bolts that fasten the base plate to the platform, which prevents passengers from tripping over those bolts and improves the appearance of the base.

[0032] The platform structure of the present invention preferably satisfies 2x≦3L and y<1.5L. If 2x is too large, the first left bar, first right bar, etc. will be too long, making it difficult to ensure the safety of people on the platform in the closed position. If y is too large, the gap between the gatepost and the edge will be too wide, making people waiting on the platform feel cramped in the closed position. Also, in the open position, it will take a long time for passengers to get on or off the platform from the boarding / alighting door. Effect of the Invention

[0033] According to the platform structure of the present invention, it is possible to easily operate the track vehicle, ensure the safety of people on the platform, and, with a simple configuration, facilitate smooth boarding and disembarking of passengers from track vehicles having multiple boarding and alighting doors with different arrangements and numbers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0035] Hereinafter, first to sixth embodiments of the present invention will be described with reference to the drawings.

[0036] Example 1 1 to 3, a platform structure 1 of Example 1 is an example of a specific aspect of the platform structure of the present invention. The platform structure 1 includes a platform 9 installed in a railway station where a track vehicle 7 is operated.

[0037] The platform 9 is a structure constructed using building materials such as concrete and steel frames. In this embodiment, the platform 9 is an existing structure that has been installed for several years to several decades. Note that the platform 9 may also be a newly constructed structure.

[0038] The upper surface of the platform 9 is a substantially flat surface on which passengers using the rail cars 7 can travel. The platform 9 has an edge 9E which is one end edge of the upper surface. The rail cars 7 stop in front of the edge 9E of the platform 9 or pass in front of the edge 9E of the platform 9.

[0039] Rail car 7 has a plurality of boarding and alighting doors 7B. Passengers using rail car 7 disembark from each boarding and alighting door 7B onto platform 9, and board from platform 9 into each boarding and alighting door 7B.

[0040] In this embodiment, the left and right directions are defined based on passengers boarding into each entrance 7B from platform 9. The left hand side of a passenger boarding into each entrance 7B from platform 9 is the left direction, and the right hand side is the right direction.

[0041] The direction perpendicular to the left-right direction and the up-down direction is defined as the front-rear direction. The direction in which passengers on the platform 9 move toward each boarding / alighting gate 7B is the front direction, and the opposite direction is the rear direction.

[0042] The left-right, up-down, and front-rear directions shown in FIG. 4 and the following figures are shown corresponding to FIGS.

[0043] As shown in Fig. 1, the edge 9E extends in the left-right direction. A left door 6L and a right door 6R are provided at each entrance 7B. The left door 6L and the right door 6R have the same length in the left-right direction. Each left door 6L slides from the left end position shown in Fig. 3 to the center position shown in Figs. 1 and 2. Each right door 6R slides from the right end position shown in Fig. 3 to the center position shown in Figs. 1 and 2.

[0044] As shown in Figures 1 and 2, when the left doors 6L and the right doors 6R are in the center position, each of the entrances 7B is closed. As shown in Figure 3, when the left door 6L is in the leftmost position and the right door 6R is in the rightmost position, each of the entrances 7B is open.

[0045] In order to ensure the safety of people on the platform 9 when the track vehicle 7 is in a traveling state before and after stopping in front of the edge 9E of the platform 9 and when it is in a state passing in front of the edge 9E of the platform 9, the platform structure 1 is equipped with a plurality of gate posts 90 shown in Fig. 1 to Fig. 6, a drive unit M1 and a control unit C1 shown in Fig. 4 and Fig. 5, and a first left bar 10L, a second left bar 20L, a first right bar 10R and a second right bar 20R shown in Fig. 1 to Fig. 6. The first left bar 10L, the second left bar 20L, the first right bar 10R and the second right bar 20R have the same length.

[0046] 1 to 3, the gate posts 90 are provided at equal intervals on the platform 9 along the edge 9E. Although the right end side of the platform 9 is not shown in FIGS. 1 to 3, the gate posts 90 are provided from the left end side to the right end side of the platform 9 along the edge 9E.

[0047] 4 and 5, each gate post 90 is a metal square tube with a closed upper end. The base side of each gate post 90 is fastened to the platform 9 by a fastening bolt or the like (not shown), and extends vertically upward.

[0048] The driving unit M1 is built into each gate post 90 and generates a driving force. The driving unit M1 has a well-known configuration having a driving source and a driving force transmission mechanism that transmits the driving force from the driving source. Specific examples of the driving source and the driving force transmission mechanism include a combination of an electric motor and a gear train, a pulley and belt, etc., and a combination of an electric hydraulic pump and a hydraulic actuator, etc.

[0049] The control unit C1 is installed in a location that does not interfere with the passage of passengers on the platform 9. The control unit C1 is connected to each drive unit M1 by a connection cable that is buried so as not to interfere with the passage of passengers.

[0050] When opening or closing the left door 6L and the right door 6R of each entrance 7B of the track car 7, the operator of the track car 7, i.e., the driver or the conductor, issues a bar opening / closing command to the operation panel to move the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R between an open position and a closed position, which will be described later. Although not shown in the figure, the control unit C1 controls each drive unit M1 based on the bar opening / closing command. That is, in this embodiment, the operator of the track car 7 has the authority and responsibility to open and close the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R, thereby eliminating the need for sensors and automatic control devices and realizing a simple configuration. The control unit C1 can also control each drive unit M1 based on commands transmitted from an operation panel operated by a station staff member or the like who manages the operation of the track car 7 on the platform 9, or commands transmitted from a central control unit that controls the entire station including the operation of the track car 7.

[0051] The first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R are rod-shaped and one each is provided on each gate post 90. The first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R are preferably made of a lightweight material that is difficult to break. In this embodiment, the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R are rod-shaped bodies made of thin-walled steel, aluminum, or fiber-reinforced resin, and are lightweight due to a hollow structure or a lightening structure.

[0052] The first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R are located forward relative to the gate post 90. The first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R are supported in a one-to-one relationship on four swing shafts that protrude forward from the front wall of the gate post 90 so as to be swingable.

[0053] The first left bar 10L, the second left bar 20L, the first right bar 10R and the second right bar 20R swing between the open position shown in Figures 3, 5 and 6(b) and the closed position shown in Figures 1, 2, 4 and 6(a) as a driving force controlled by the control unit C1 is transmitted from the drive unit M1 via each swing shaft.

[0054] In this embodiment, the first left bar 10L and the second left bar 20L supported by the gatepost 90 located at the left end of the platform 9 are not expected to allow passengers to pass through, so they are disconnected from the drive unit M1 and fixed in the open position. Although not shown, the first right bar 10R and the second right bar 20R supported by the gatepost 90 located at the right end of the platform 9 are also fixed in the open position.

[0055] As shown in Fig. 6, the first left bar 10L can swing about a first left axis X1L. The second left bar 20L can swing about a second left axis X2L. The first right bar 10R can swing about a first right axis X1R. The second right bar 20R can swing about a second right axis X2R.

[0056] The first left axis X1L, the second left axis X2L, the first right axis X1R and the second right axis X2R extend in the front-rear direction. The second left axis X2L is spaced vertically downward from the first left axis X1L. The second right axis X2R is spaced vertically downward from the first right axis X1R.

[0057] The first right axis X1R and the second right axis X2R are located at a position separated to the right from the first left axis X1L and the second left axis X2L. The first left axis X1L and the first right axis X1R have the same height. The second left axis X2L and the second right axis X2R have the same height.

[0058] As shown in Figs. 4 and 5, the first left bar 10L is composed of a first left base portion 11L, a first left bent portion 12L, and a first left tip portion 13L.

[0059] The first left base portion 11L extends in an elongated shape in the radially outward direction of the first left axis X1L. The first left bent portion 12L is connected to the first left base portion 11L and bent forward so as to move away from the gatepost 90. The first left tip portion 13L is connected to the first left bent portion 12L and extends in an elongated shape in the same direction as the first left base portion 11L.

[0060] The first right bar 10R is composed of a first right base portion 11R, a first right bent portion 12R, and a first right tip portion 13R.

[0061] The first right base portion 11R extends in an elongated shape in the radially outward direction of the first right axis X1R. The first right bent portion 12R is connected to the first right base portion 11R and bent forward so as to move away from the gatepost 90. The first right tip portion 13R is connected to the first right bent portion 12R and extends in an elongated shape in the same direction as the first right base portion 11R.

[0062] In this embodiment, the first left bar 10L, the second left bar 20L, the first right bar 10R and the second right bar 20R are common parts, and cost reduction is achieved by reducing the number of parts.

[0063] 4, the first left bar 10L and the second left bar 20L protrude leftward from the gate post 90 in the closed position. The first right bar 10R and the second right bar 20R protrude rightward from the gate post 90 in the closed position.

[0064] The first left bar 10L, the second left bar 20L, the first right bar 10R and the second right bar 20R in the closed position prohibit people from disembarking from each boarding / alighting door 7B onto the platform 9 and from boarding from the platform 9 into each boarding / alighting door 7B.

[0065] As shown in FIG. 6(a), the left-right length from the tip of the first left bar 10L in the closed position to the first left axis center X1L, the left-right length from the tip of the second left bar 20L in the closed position to the second left axis center X2L, the left-right length from the tip of the first right bar 10R in the closed position to the first right axis center X1R, and the left-right length from the tip of the second right bar 20R in the closed position to the second right axis center X2R are all equal in length LA1.

[0066] 5, the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R extend downward in the open position. In the open position, the second left bar 20L is located between the first left front portion 13L and the front wall of the gate post 90. In the open position, the second right bar 20R is located between the first right front portion 13R and the front wall of the gate post 90.

[0067] The first left bar 10L, the second left bar 20L, the first right bar 10R and the second right bar 20R in the open position allow people to disembark from each boarding / alighting door 7B onto the platform 9 and to board from the platform 9 into each boarding / alighting door 7B.

[0068] As shown in Figures 1 to 3, the platform 9 is not provided with any obstacles that are fixed between two adjacent gateposts 90 and extend in the left-right direction to prevent passengers from getting on and off at each boarding / alighting entrance 7B.

[0069] As shown in Fig. 2, the inner width of each entrance 7B in the left-right direction is 2L. The interval between each gate post 90 in the left-right direction is 2x. As shown in Fig. 4, the distance between each gate post 90 and the edge portion 9E in the front-rear direction is y.

[0070] As shown in Fig. 6, the outer width in the left-right direction of each gate post 90 is defined as p. As shown in Fig. 6(b), the outer width in the left-right direction of a set of first left bar 10L, second left bar 20L, first right bar 10R, and second right bar 20R supported by each gate post 90 in the open position is defined as w.

[0071] Specific examples of L, x, y, p, and w are as follows: In this embodiment, L=650 mm, x=660 mm, y=660 mm, p=200 mm, and w=198 mm.

[0072] The platform structure 1 satisfies 2L≦2x≦3L, L≦y<1.5L, L>p, and w≦p. In particular, in this embodiment, 2L≦2x≦2.2L, L≦y<1.2L, and 0.4L>p are satisfied.

[0073] If 2L>2x, one boarding / alighting entrance 7B may overlap with two gate posts 90 in the front-to-rear direction, which is not preferable.

[0074] If 2x>3L, the lengths of the first left bar 10L, the second left bar 20L, the first right bar 10R and the second right bar 20R become too large, making it difficult to ensure the safety of people on the platform in the closed position. In addition, the drive unit M1 becomes too large accordingly, which is undesirable.

[0075] If L>y, passengers getting on or off at an entrance 7B (for example, 7B2, 7B3, 7B4 shown in FIG. 3) that overlaps with the gatepost 90 in the front-to-rear direction must make a large detour around the gatepost 90, which is not preferable.

[0076] When y≧1.5L, the gap between the gatepost and the edge becomes excessively wide, and people waiting on the platform 9 tend to feel cramped when the gate is closed. Also, when the gate is open, the time required for passengers to get on or off the train from the boarding / alighting door 7B tends to be long, which is not preferable.

[0077] If L≦p, passengers getting on or off at an entrance 7B (for example, 7B2, 7B3, 7B4 shown in FIG. 3) that overlaps with the gatepost 90 in the front-to-rear direction must make a large detour around the gatepost 90, which is not preferable.

[0078] w≦p means that the sets of first left bar 10L, second left bar 20L, first right bar 10R, and second right bar 20R supported by each of the gate posts 90 do not protrude from each gate post 90 in the open position. If w>p, the parts of the sets of first left bar 10L, second left bar 20L, first right bar 10R, and second right bar 20R supported by each of the gate posts 90 that protrude from each gate post 90 in the open position are likely to interfere with passengers, which is not preferable.

[0079] <Action and effect> In the platform structure 1 of Example 1, the first left bar 10L, the second left bar 20L, the first right bar 10R and the second right bar 20R, each supported by one of the gate posts 90, are driven by a drive unit M1 built into each of the gate posts 90, and swing between an open position shown in Figure 3, etc. and a closed position shown in Figure 1, etc.

[0080] When the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R are in the open position, they allow passengers to get on and off at each of the boarding and alighting doors 7B. When the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R are in the closed position, they prohibit passengers from getting on and off at each of the boarding and alighting doors 7B.

[0081] Here, in this platform structure 1, as shown in Figs. 1 to 3, the platform 9 is not provided with any obstacle that is fixed between two adjacent gate posts 90 in a state of extending in the left-right direction and that prohibits passengers from getting on and off at each boarding / alighting opening 7B. This platform structure 1 satisfies 2L ≦ 2x ≦ 3L. As a result, when multiple types of track cars 7 with different arrangements and numbers of boarding / alighting openings 7B stop in front of the edge 9E of the platform 9, a part of each boarding / alighting opening 7B overlaps a part of each gate post 90 in the front-rear direction, while the other part of each boarding / alighting opening 7B does not overlap with each gate post 90 in the front-rear direction.

[0082] This platform structure 1 satisfies L≦y<1.5L, L>p, and w≦p. As a result, as shown in FIG. 3, when the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R swing to the open position and passengers start getting off and boarding at each boarding / alighting door 7B, passengers getting off or boarding at the boarding / alighting door 7B (e.g., 7B2, 7B3, 7B4) that overlaps with the gate post 90 in the front-rear direction can pass by the side of the overlapping gate post 90 without making a large detour. Also, at that time, passengers getting off or boarding at the boarding / alighting door 7B (e.g., 7B1) that does not overlap with the gate post 90 in the front-rear direction do not need to detour around the gate post 90 that does not overlap.

[0083] Therefore, even if the rail car 7 stops with each boarding / alighting entrance 7B overlapping with each gatepost 90 in the front-rear direction, there is no hindrance to passengers getting on and off. Therefore, the rail car 7 is easy to operate.

[0084] Furthermore, this platform structure 1 can be achieved by simply lining up multiple sets of gate posts 90, first left bar 10L, second left bar 20L, first right bar 10R and second right bar 20R on the platform 9 along the edge 9E.

[0085] Therefore, the platform structure 1 of Example 1 makes it easy to operate the track vehicle 7, ensures the safety of people on the platform 9, and, with a simple configuration, can facilitate passengers' disembarking and boarding to and from track vehicles 7 having multiple boarding and alighting entrances 7B with different arrangements and numbers.

[0086] Furthermore, according to this platform structure 1, even if a set of the gatepost 90, the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R fails and the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R of that set cannot swing to the open position, L≦y<1.5L is satisfied, and the set of the gatepost 90, the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R next to the failed set operates normally, so that passengers can easily bypass the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R of the failed set. As a result, this platform structure 1 can suppress the occurrence of confusion on the platform 9 due to partial failure. Furthermore, according to this platform structure 1, waterproofing and dustproofing measures need only be taken for the parts supporting the swinging shafts of the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R in each gate post 90. As a result, this platform structure 1 can simplify maintenance work compared to sliding doors, etc., and can suppress a decrease in durability even if it is installed in a place where it is likely to be exposed to rain, etc. In addition, according to this platform structure 1, since the width of the gate post 90 is narrowed by satisfying L>p, the gate post 90 is less likely to receive wind pressure accompanying the passage of the track car 7, etc., and further, since the gate post 90 is separated from the edge part 9E of the platform 9 by satisfying L≦y, the gate post 90 is even less likely to receive wind pressure accompanying the passage of the track car 7. As a result, the durability of the part fastening the gate post 90 to the platform 9 is improved. Furthermore, with this platform structure 1, by satisfying w≦p, the widths of the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R are narrowed. Therefore, the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R are less susceptible to wind pressure caused by the passage of the track cars 7 when they swing to the closed position. As a result, with this platform structure 1, reinforcement work for the platform 9 can be simplified or omitted, and thus installation costs can be reduced.

[0087] In addition, in this platform structure 1, the second left axis X2L is spaced vertically downward from the first left axis X1L, and the second right axis X2R is spaced vertically downward from the first right axis X1R. The first left axis X1L and the first right axis X1R have the same height, and the second left axis X2L and the second right axis X2R have the same height. In the conventional platform structure, as shown in FIG. 1 of Patent Document 1, the adjacent left and right pillars are separate, the right side wall of the left pillar and the left side wall of the right pillar are adjacent to each other, and each pair of the left and right pillars incorporates two drive units in total. In contrast, in this platform structure 1, one pillar 90 does not have the right side wall of the left pillar and the left side wall of the right pillar according to the conventional platform structure, and only incorporates one drive unit M1. As a result, the platform structure 1 makes it easier to reduce the left-right outer width p of each gate post 90 compared to the left-right outer width of the adjacent left and right gate posts in the conventional platform structure. Also, in the conventional platform structure, the second left axis is located at a position spaced downward and to the left from the first left axis, and the second right axis is located at a position spaced downward and to the right from the first right axis. In contrast, in the platform structure 1, the second left axis X2L is located at a position spaced vertically downward from the first left axis X1L and is not spaced to the left from the first left axis X1L. Also, the second right axis X2R is located at a position spaced vertically downward from the first right axis X1R and is not spaced to the right from the first right axis X1R. As a result, the platform structure 1 makes it easier to reduce the left-right outer width p of each gate post 90 compared to the left-right outer width of the adjacent left and right gate posts in the conventional platform structure. Therefore, according to this platform structure 1, it is easy to reduce the extent to which passengers getting on or off at boarding / alighting entrances 7B (e.g., 7B2, 7B3, 7B4) that overlap with the gate pillars 90 in the front-to-rear direction have to make a detour when passing by the side of the overlapping gate pillars 90. As a result, this platform structure 1 can further facilitate smoother boarding and disembarking of passengers from rail cars 7 having multiple boarding / alighting entrances 7B with different arrangements and numbers.

[0088] Furthermore, in this platform structure 1, as shown in Fig. 5, the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R extend downward in the open position. In the open position, the second left bar 20L is located between the first left end portion 13L of the first left bar 10L and the front wall of the gatepost 90. In the open position, the second right bar 20R is located between the first right end portion 13R of the first right bar 10R and the front wall of the gatepost 90. With this configuration, the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R extending downward in the open position are less likely to impair the visibility of the platform 9 compared to the case where the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R extend upward in the open position. In addition, the first left bent portion 12L of the first left bar 10L and the first right bent portion 12R of the first right bar 10R prevent the first left base portion 11L of the first left bar 10L and the first right base portion 11R of the first right bar 10R from becoming bulky in the front-to-rear direction when the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R are in the open position.

[0089] Example 2 As shown in FIG. 7, the platform structure of Example 2 is the same as the platform structure 1 of Example 1 except that the first left bar 10L, the second left bar 20L, the first right bar 10R and the second right bar 20R extend upward when in the open position.

[0090] Other configurations of the second embodiment are similar to those of the first embodiment. Therefore, the same configurations as those of the first embodiment are denoted by the same reference numerals and the description thereof will be omitted.

[0091] <Action and effect> The platform structure of Example 2, like the platform structure 1 of Example 1, makes it easy to operate the track vehicle 7 and ensures the safety of people on the platform 9, while being simply configured to facilitate smooth boarding and disembarking of passengers from track vehicles 7 having multiple boarding and alighting entrances 7B with different arrangements and numbers.

[0092] Example 3 As shown in FIGS. 8 to 10, the platform structure of the third embodiment is modified as follows from the platform structure 1 of the first embodiment.

[0093] This platform structure has been modified so that the vertical distance between the first left axis X1L and the second left axis X2L, and the vertical distance between the first right axis X1R and the second right axis X2R are larger than in Example 1.

[0094] The platform structure has been modified so that the first left bar 10L, the second left bar 20L, the first right bar 10R and the second right bar 20R extend upwardly when in the open position shown in Figures 9 and 10(b).

[0095] This platform structure is modified to further include a third left bar 30L that can swing about a third left axis X3L and a third right bar 30R that can swing about a third right axis X3R, as shown in Figures 8 to 10. The third left bar 30L and the third right bar 30R are located forward of the gate post 90.

[0096] As shown in Fig. 10, the third left axis X3L and the third right axis X3R extend in the front-rear direction. The third left axis X3L is located between the first left axis X1L and the second left axis X2L in the vertical direction. The third right axis X3R is located between the first right axis X1R and the second right axis X2R in the vertical direction. The third left axis X3L and the third right axis X3R are at the same height.

[0097] The third left bar 30L swings between an open position in which it extends upward along the gate post 90, as shown in Figures 9 and 10(b), and a closed position in which it protrudes to the left from the gate post 90, as shown in Figures 8 and 10(a), by a driving force controlled by the control unit C1.

[0098] The third right bar 30R swings between an open position in which it extends upward along the gate post 90, as shown in Figures 9 and 10(b), and a closed position in which it protrudes to the right from the gate post 90, as shown in Figures 8 and 10(a), by a driving force controlled by the control unit C1.

[0099] As shown in Figure 10(b), the sets of first left bar 10L, second left bar 20L, third left bar 30L, first right bar 10R, second right bar 20R and third right bar 30R supported by each gate post 90 do not protrude from each gate post 90 in the open position.

[0100] In this embodiment, the first left bar 10L, the second left bar 20L, the first right bar 10R, the second right bar 20R, the third left bar 30L, and the third right bar 30R are common parts, and the cost is reduced by reducing the number of parts. The first left bar 10L, the second left bar 20L, the first right bar 10R, the second right bar 20R, the third left bar 30L, and the third right bar 30R are all equal in length.

[0101] As shown in FIG. 10(a), the left-right length from the tip of the first left bar 10L in the closed position to the first left axis center X1L, the left-right length from the tip of the second left bar 20L in the closed position to the second left axis center X2L, the left-right length from the tip of the third left bar 30L in the closed position to the third left axis center X3L, the left-right length from the tip of the first right bar 10R in the closed position to the first right axis center X1R, the left-right length from the tip of the second right bar 20R in the closed position to the second right axis center X2R, and the left-right length from the tip of the third right bar 30R in the closed position to the third right axis center X3R are all equal in length LA1.

[0102] Other configurations of the embodiment 3 are similar to those of the embodiment 1. Therefore, the same configurations as those of the embodiment 1 are denoted by the same reference numerals and the description thereof will be omitted.

[0103] <Action and effect> The platform structure of Example 3, like the platform structures 1 of Examples 1 and 2, makes it easy to operate the track vehicles 7 and ensures the safety of people on the platform 9, while using a simple configuration to facilitate smooth boarding and disembarking of passengers from track vehicles 7 having multiple boarding and alighting entrances 7B with different arrangements and numbers.

[0104] This platform structure further includes a third left bar 30L and a third right bar 30R. The third left axis X3L is located between the first left axis X1L and the second left axis X2L in the vertical direction. The third right axis X3R is located between the first right axis X1R and the second right axis X2R in the vertical direction. The third left axis X3L and the third right axis X3R are at the same height. With this configuration, the first left bar 10L and the first right bar 10R in the closed position, the second left bar 20L and the second right bar 20R in the closed position, and the third left bar 30L and the third right bar 30R in the closed position can reduce the vertical gap between them. As a result, this platform structure can reliably prohibit passengers from disembarking and boarding at each boarding and alighting gate 7B when the first left bar 10L, the second left bar 20L, the third left bar 30L, the first right bar 10R, the second right bar 20R and the third right bar 30R are in the closed position.

[0105] Example 4 As shown in FIGS. 11 to 13, the platform structure of the fourth embodiment is modified from the platform structure 1 of the first embodiment as follows.

[0106] This platform structure has been modified so that the vertical distance between the first left axis X1L and the second left axis X2L, and the vertical distance between the first right axis X1R and the second right axis X2R are larger than in Example 1.

[0107] This platform structure has been modified so that the first left bar 10L and the first right bar 10R are positioned rearward relative to the gatepost 90.

[0108] In this platform structure, the shape of the second left bar 20L and the second right bar 20R is changed to a rod shape without bending, and the second left bar 20L and the second right bar 20R are modified so that they extend upward in the open position.

[0109] This platform structure is modified to further include a third left bar 430L that can swing about a third left axis X3L and a third right bar 430R that can swing about a third right axis X3R. The third left bar 430L and the third right bar 430R are located rearward relative to the gate post 90.

[0110] As shown in Fig. 13, the third left axis X3L and the third right axis X3R extend in the front-rear direction. The third left axis X3L is located between the first left axis X1L and the second left axis X2L in the vertical direction. The third right axis X3R is located between the first right axis X1R and the second right axis X2R in the vertical direction. The third left axis X3L and the third right axis X3R are at the same height.

[0111] The third left bar 430L swings between an open position in which it extends downward along the gate post 90, as shown in Figures 12, 13(b) and 13(c), and a closed position in which it protrudes to the left from the gate post 90, as shown in Figures 11 and 13(a), by a driving force controlled by the control unit C1.

[0112] The third right bar 430R swings between an open position in which it extends downward along the gate post 90, as shown in Figures 12, 13(b) and 13(c), and a closed position in which it protrudes to the right from the gate post 90, as shown in Figures 11 and 13(a), by a driving force controlled by the control unit C1.

[0113] In the open position, the third left bar 430L is located between the first left front portion 13L of the first left bar 10L and the rear wall of the gate post 90. In the open position, the third right bar 430R is located between the first right front portion 13R of the first right bar 10R and the rear wall of the gate post 90.

[0114] As shown in Figures 13(b) and (c), the sets of first left bar 10L, second left bar 20L, third left bar 430L, first right bar 10R, second right bar 20R and third right bar 430R supported by each gate post 90 do not protrude from each gate post 90 in the open position.

[0115] In this embodiment, the second left bar 20L, the second right bar 20R, the third left bar 430L, and the third right bar 430R are common parts, and the cost is reduced by reducing the number of parts. The first left bar 10L, the second left bar 20L, the first right bar 10R, the second right bar 20R, the third left bar 430L, and the third right bar 430R are all equal in length.

[0116] As shown in FIG. 13(a), the left-right length from the tip of the first left bar 10L in the closed position to the first left axis center X1L, the left-right length from the tip of the second left bar 20L in the closed position to the second left axis center X2L, the left-right length from the tip of the third left bar 430L in the closed position to the third left axis center X3L, the left-right length from the tip of the first right bar 10R in the closed position to the first right axis center X1R, the left-right length from the tip of the second right bar 20R in the closed position to the second right axis center X2R, and the left-right length from the tip of the third right bar 430R in the closed position to the third right axis center X3R are all equal in length LA1.

[0117] Other configurations of the fourth embodiment are similar to those of the first embodiment. Therefore, the same components as those of the first embodiment are denoted by the same reference numerals and the description thereof will be omitted.

[0118] <Action and effect> The platform structure of Example 4, like the platform structures 1 of Examples 1 to 3, makes it easy to operate the track vehicle 7 and ensures the safety of people on the platform 9, while using a simple configuration to facilitate smooth boarding and disembarking of passengers from track vehicles 7 having multiple boarding and alighting entrances 7B with different arrangements and numbers.

[0119] This platform structure further includes a third left bar 430L and a third right bar 430R. The third left axis X3L is located between the first left axis X1L and the second left axis X2L in the vertical direction. The third right axis X3R is located between the first right axis X1R and the second right axis X2R in the vertical direction. The third left axis X3L and the third right axis X3R have the same height. With this configuration, the first left bar 10L and the first right bar 10R in the closed position, the second left bar 20L and the second right bar 20R in the closed position, and the third left bar 430L and the third right bar 430R in the closed position can reduce the vertical gap between them. As a result, this platform structure can reliably prohibit passengers from disembarking or boarding at each boarding / alighting gate 7B when the first left bar 10L, the second left bar 20L, the third left bar 430L, the first right bar 10R, the second right bar 20R and the third right bar 430R are in the closed position.

[0120] Furthermore, in this platform structure, the first left bar 10L, the third left bar 430L, the first right bar 10R and the third right bar 430R extend downward in the open position. The third left bar 430L is located between the first left end portion 13L of the first left bar 10L and the rear wall of the gate post 90 in the open position. The third right bar 430R is located between the first right end portion 13R of the first right bar 10R and the rear wall of the gate post 90 in the open position. And the second left bar 20L and the second right bar 20R are located forward of the gate post 90 and extend upward in the open position. With this configuration, the first left bar 10L, the third left bar 430L, the first right bar 10R, and the third right bar 430R extending downward in the open position are less likely to impair visibility of the platform 9 compared to a case in which the first left bar 10L, the third left bar 430L, the first right bar 10R, and the third right bar 430R extend upward in the open position. In addition, the first left bent portion 12L of the first left bar 10L and the first right bent portion 12R of the first right bar 10R can prevent the first left base portion 11L of the first left bar 10L and the first right base portion 11R of the first right bar 10R from becoming bulky in the front-rear direction when the first left bar 10L, the third left bar 430L, the first right bar 10R, and the third right bar 430R are in the open position. Furthermore, even if the second left bar 20L and the second right bar 20R that extend upward in the open position are made longer, the visibility of the platform 9 is not likely to be impaired.

[0121] Example 5 As shown in FIGS. 14 to 16, the platform structure of the fifth embodiment is modified as follows with respect to the platform structure 1 of the first embodiment.

[0122] 16, in this platform structure, the outer width p in the left-right direction of each gate post 90 is changed to be smaller than the outer width p according to Example 1. Accordingly, the distances by which the first right axis X1R and the second right axis X2R are separated to the right from the first left axis X1L and the second left axis X2L are also changed to be smaller than those in Example 1.

[0123] This platform structure employs a first left bar 510L, a second left bar 520L, a first right bar 510R and a second right bar 520R instead of the first left bar 10L, the second left bar 20L, the first right bar 10R and the second right bar 20R of Example 1.

[0124] 14, the first left bar 510L in the closed position protrudes slightly leftward and upward from the gate post 90, then bends and protrudes to the left. The first right bar 510R in the closed position protrudes slightly rightward and upward from the gate post 90, then bends and protrudes to the right.

[0125] The second left bar 520L protrudes leftward from the gate post 90 in the closed position. The second right bar 520R protrudes rightward from the gate post 90 in the closed position.

[0126] When the first left bar 510L, the second left bar 520L, the first right bar 510R and the second right bar 520R are in the closed position, their cross sections have a flattened rectangular cross section whose length in the front-to-back direction is significantly greater than its length in the up-down direction.

[0127] 15, in the open position, the first left bar 510L protrudes slightly to the left and downward from the gate post 90, then bends and protrudes downward. In the open position, the first right bar 510R protrudes slightly to the right and downward from the gate post 90, then bends and protrudes downward.

[0128] In the open position, the second left bar 520L and the second right bar 520R protrude downward from the gate post 90. In this state, the upper portions of the second left bar 520L and the second right bar 520R are sandwiched between the lower portions of the first left bar 510L and the first right bar 510R.

[0129] As shown in FIG. 16(b), in a set of a first left bar 510L, a second left bar 520L, a first right bar 510R and a second right bar 520R supported on each gate post 90, the outer width w in the left-right direction in the open position satisfies w≦p.

[0130] As shown in Figure 16(a), the left-right length from the tip of the first left bar 510L in the closed position to the first left axis center X1L, the left-right length from the tip of the second left bar 520L in the closed position to the second left axis center X2L, the left-right length from the tip of the first right bar 510R in the closed position to the first right axis center X1R, and the left-right length from the tip of the second right bar 520R in the closed position to the second right axis center X2R are all equal in length LA2.

[0131] Other configurations of the embodiment 5 are similar to those of the embodiment 1. Therefore, the same configurations as those of the embodiment 1 are denoted by the same reference numerals and the description thereof will be omitted.

[0132] <Action and effect> The platform structure of Example 5, like the platform structures 1 of Examples 1 to 4, makes it easy to operate the track vehicle 7 and ensures the safety of people on the platform 9, while using a simple configuration to facilitate smooth boarding and disembarking of passengers from track vehicles 7 having multiple boarding and alighting entrances 7B with different arrangements and numbers.

[0133] Example 6 As shown in FIGS. 17 to 20, the platform structure of the sixth embodiment is modified from the platform structure 1 of the first embodiment as follows.

[0134] In this platform structure, a gatepost 90 is modified to have a body portion 91 shown in FIGS. 17, 18 and 20, and a base portion 93 shown in FIGS.

[0135] As shown in Fig. 17, the main body 91 supports the first left bar 10L, the second left bar 20L, the first right bar 10R, and the second right bar 20R in a swingable manner. As shown in Fig. 18, a plurality of circular holes 91H are formed in the side wall at the lower end of the main body 91. The lower end of the main body 91 is open, and a connection cable M1C extending from the drive unit M1 extends downward.

[0136] 17 and 20, the base portion 93 is installed on the platform 9. The main body portion 91 has a lower end portion which fits into the base portion 93 and is fastened to the base portion 93.

[0137] More specifically, as shown in FIGS. 19 and 20, the base portion 93 has a base plate 94, a mounting plate 95, a fitting portion 97, an intermediate plate 96, and a plurality of bolts 94B, 95B, each of which is made of metal.

[0138] The base plate 94 is a stepped disk in which a large diameter disk and a small diameter disk are integrally formed coaxially. The small diameter disk protrudes upward from the upper surface of the large diameter disk. The base plate 94 has a cable insertion hole 94C that passes through its center in the vertical direction.

[0139] 19 is inserted through the cable insertion hole 94C. Although not shown, the connection cable C1C extends from the control unit C1 and passes through a connection cable passage formed in the platform 9 before being inserted into the cable insertion hole 94C from below.

[0140] 19 and 20, the base plate 94 has a plurality of screw holes 94H in the center. Each screw hole 94H is recessed downward from the upper surface of the small diameter disk and surrounds a cable insertion hole 94C.

[0141] The base plate 94 has a plurality of countersunk holes 94Z on the outer periphery of the small diameter disk. Each of the countersunk holes 94Z passes through the large diameter disk in the vertical direction.

[0142] As shown in FIG. 20, a plurality of bolts 94B are inserted into the countersunk holes 94Z and screwed into female threaded anchors 94A embedded in the platform 9, thereby fastening the base plate 94 to the platform 9.

[0143] 19 and 20, the mounting plate 95 is a disk having the same outer diameter as the outer diameter of the large diameter disk of the base plate 94. As shown in Fig. 20, the lower surface of the mounting plate 95 is gently inclined with respect to the horizontal plane.

[0144] The mounting plate 95 has a cable insertion hole 95C that passes through the center thereof in the up-down direction. The connection cable C1C shown in FIG. 19 is also inserted through the cable insertion hole 95C.

[0145] 19 and 20, the mounting plate 95 has a plurality of upper through-holes 95H in the center thereof which correspond to the respective screw holes 94H. Each of the upper through-holes 95H passes through the mounting plate 95 in the vertical direction and surrounds a cable insertion hole 95C.

[0146] The fitting portion 97 has a rectangular cylindrical shape surrounding the cable insertion hole 95C and each upper insertion hole 95H, and protrudes upward from the upper surface of the mounting plate 95. An upper portion of the fitting portion 97 can be inserted into the lower end portion of the main body portion 91 from below and fitted into the lower end portion.

[0147] The upper portion of the fitting portion 97 has a plurality of screw holes 97H which align with the respective circular holes 91H of the main body portion 91. The connection cable C1C shown in FIG.

[0148] 19 and 20, the intermediate plate 96 is a disk having an outer diameter equal to that of the large diameter disk of the base plate 94. The intermediate plate 96 has an intermediate insertion hole 96H in the center. The inner diameter of the intermediate insertion hole 96H is slightly larger than the outer diameter of the small diameter disk of the base plate 94. The upper surface of the intermediate plate 96 is gently inclined with respect to the horizontal plane.

[0149] 20 , the intermediate plate 96 is placed on the upper surface of the large disk of the base plate 94 fastened to the platform 9. The small disk of the base plate 94 is positioned in the intermediate insertion hole 96H of the intermediate plate 96. This allows the intermediate plate 96 to rotate around the small disk of the base plate 94.

[0150] The mounting plate 95 is placed on the upper surface of the intermediate plate 96 , such that the intermediate plate 96 is sandwiched between the base plate 94 and the mounting plate 95 .

[0151] In this state, the mounting plate 95 and the intermediate plate 96 are fastened to the base plate 94 by inserting the bolts 95B from above into the upper through-holes 95H and the intermediate through-holes 96H and screwing them into the screw holes 94H. In this case, with the mounting plate 95 and the intermediate plate 96 temporarily fastened to the base plate 94 by the bolts 95B, the intermediate plate 96 can be rotated relative to the mounting plate 95 to easily adjust the inclination of the fitting portion 97 relative to the vertical direction. In addition, the vertical height of the main body 91 can be adjusted by appropriately selecting a plurality of types of intermediate plates 96 having different thicknesses or by appropriately selecting a plurality of types of shims having different thicknesses and placing them between the intermediate plate 96 and the base plate 94. As a result, height adjustment using shims or the like when fastening the base plate 94 to the platform 9 can be simplified or omitted, and the heights of the respective tips of the first left bar 10L and the first right bar 10R in the open position, and the heights of the respective tips of the second left bar 20L and the second right bar 20R in the open position can be easily aligned.

[0152] Then, after connecting the connector of the connection cable C1C and the connector of the connection cable M1C, the upper portion of the fitting portion 97 is fitted into the lower end portion of the main body portion 91, and multiple bolts 91B are inserted into each of the circular holes 91H of the main body portion 91 and screwed into each of the screw holes 97H of the fitting portion 97, thereby fastening the main body portion 91 to the base portion 93.

[0153] <Action and effect> The platform structure of Example 6, like the platform structures 1 of Examples 1 to 5, makes it easy to operate the track vehicle 7 and ensures the safety of people on the platform 9, while using a simple configuration to facilitate smooth boarding and disembarking of passengers from track vehicles 7 having different arrangements and numbers of boarding and alighting entrances 7B.

[0154] In addition, this platform structure has a gate post 90 having a base portion 93 and a main body portion 91, and the main body portion 91 can be easily attached and detached from the base portion 93, thereby simplifying the replacement work of the main body portion 91 and reducing the time and cost required.

[0155] Furthermore, in this platform structure, the foundation portion 93 has a base plate 94, a mounting plate 95, a fitting portion 97, an intermediate plate 96, and a plurality of bolts 95B. The upper surface of the intermediate plate 96 and the lower surface of the mounting plate 95 are inclined with respect to the horizontal plane. With this configuration, the fitting portion 97 can be easily adjusted to eliminate the inclination of the fitting portion 97 with respect to the vertical direction by rotating the intermediate plate 96 with respect to the mounting plate 95 in a state in which the mounting plate 95 and the intermediate plate 96 are temporarily fixed to the base plate 94 with the plurality of bolts 95B. As a result, the main body portion 91 is unlikely to incline with respect to the vertical direction in a state in which it is fastened to the fitting portion 97. In addition, the intermediate plate 96 and the mounting plate 95 cover the plurality of bolts 94B that fasten the base plate 94 to the platform 9, so that passengers can be prevented from tripping over each bolt 94B, and the appearance of the base portion 93 can be improved.

[0156] In the above, the present invention has been described based on Examples 1 to 6. However, the present invention is not limited to the above Examples 1 to 6, and it goes without saying that the present invention can be modified and applied as appropriate without departing from the spirit of the present invention.

[0157] For example, the platform structure of Example 6 is the platform structure 1 of Example 1 provided with a base portion 93 and a main body portion 91, but the present invention is not limited to this configuration. The platform structure 1 of Examples 2 to 5 is also included in the present invention in a configuration in which a similar base portion 93 and a main body portion 91 are provided. In the case of a configuration in which a similar base portion 93 and a main body portion 91 are provided in the platform structure of Example 3, the main body portion 91 swingably supports the first left bar 10L, the second left bar 20L, the third left bar 30L, the first right bar 10R, the second right bar 20R, and the third right bar 30R. In the case of a configuration in which a similar base portion 93 and a main body portion 91 are provided in the platform structure of Example 4, the main body portion 91 swingably supports the first left bar 10L, the second left bar 20L, the third left bar 430L, the first right bar 10R, the second right bar 20R, and the third right bar 430R.
