DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments will be described with reference to the drawings, in which the same or corresponding parts are designated by the same reference numerals.

[0011] [Embodiment 1] Figure 1 shows the configuration of a platform door system 800 according to this embodiment. This platform door system 800 includes multiple platform doors 600 installed on each platform PF, and a control device 700 that controls the multiple platform doors 600.

[0012] A plurality of platform doors 600 are lined up along the track RT at the edge of the platform PF. Each platform door 600 separates a passenger waiting space SA above the platform PF from a track space SB through which the railway vehicles 900 travel.

[0013] Each platform door 600 includes a door pocket 610 fixed to the platform PF and a door body 620 that moves forward and backward from the door pocket 610. In other words, the door pocket 610 has a structure that can accommodate the door body 620. The door pocket 610 is an example of a fence structure according to the present disclosure.

[0014] The advancement of door body 620 from door pocket 610 corresponds to the closing of platform door 600. The retreat of door body 620 into door pocket 610 corresponds to the opening of platform door 600. When platform door 600 opens and boarding door 910 of stopped railway car 900 opens, passenger waiting space SA and the passenger compartment of railway car 900 are connected.

[0015] Additionally, a drive control mechanism 630 that moves the door body 620 forward and backward from the door pocket 610 is housed inside the door pocket 610. The drive control mechanisms 630 of each platform door 600 are collectively controlled by a control device 700. The control device 700 and each drive control mechanism 630 are connected to each other via a wired or wireless network so that they can communicate with each other.

[0016] The greatest feature of the platform door system 800 according to this embodiment is the structure of the door pocket 610 as a fence structure of each platform door 600. Therefore, the structure of the door pocket 610 will be described below.

[0017] As shown in Figure 2, the door pocket 610 comprises a first panel 100 having a surface 100a facing the passenger waiting space SA, a second panel 200 having a surface 200a facing the track space SB, and a framework 500 to which the first panel 100 and the second panel 200 are attached.

[0018] The first panel 100 and the second panel 200 face each other via a storage space SP. The storage space SP between the first panel 100 and the second panel 200 accommodates the door body 620, the drive control mechanism 630, and the like shown in FIG.

[0019] To facilitate the following explanation, a right-handed XYZ Cartesian coordinate system is defined, in which the direction perpendicular to the surface 100a of the first panel 100 and the surface 200a of the second panel 200 is the X-axis direction, and the vertical direction is the Y-axis direction. In this case, the Z-axis direction coincides with the length direction of the track RT shown in FIG.

[0020] In this embodiment, the direction from the first panel 100 to the second panel 200 is defined as the positive direction of the X-axis (hereinafter referred to as the positive X-axis direction). In this case, the positive Y-axis (hereinafter referred to as the positive Y-axis direction) is upward.

[0021] Each of the first panel 100 and the second panel 200 is formed into a rectangular shape when viewed in the X-axis direction. The framework 500 is assembled into a rectangular frame shape when viewed in the X-axis direction. Of the multiple components of the framework 500, only the upper frame member 300 and the lower frame member 400, which face each other in the Y-axis direction, are shown in Figure 2. The upper frame member 300 is positioned above the lower frame member 400.

[0022] In the door pocket 610 according to this embodiment, the first panel 100 is designed to be easily attached to and detached from the framework 500. That is, in this embodiment, the first panel 100 is an example of a panel according to the present disclosure. Therefore, the configuration related to the attachment and detachment of the first panel 100 will be described below.

[0023] As described above, the first panel 100 is formed into a rectangular shape when viewed in the X-axis direction. Therefore, the surface 100a of the first panel 100 has a pair of edge portions 100a1 and 100a2 that face each other in the Y-axis direction, and a pair of edge portions (not shown) that face each other in the Z-axis direction. Each of the pair of edge portions 100a1 and 100a2 that face each other in the Y-axis direction extends in the Z-axis direction. Each of the pair of edge portions (not shown) that face each other in the Z-axis direction also extends in the Y-axis direction.

[0024] The upper frame member 300 is disposed above the first panel 100, and extends in the Z-axis direction along an edge 100a1 located at the upper end of the surface 100a of the first panel 100. The lower frame member 400 is disposed below the first panel 100, and extends in the Z-axis direction along an edge 100a2 located at the lower end of the surface 100a of the first panel 100.

[0025] A lower edge portion 100a2 of the first panel 100 is fixed to the lower frame member 400. This point will be described in detail below.

[0026] The first panel 100 has a bottom plate portion 190 that extends in the positive direction of the X-axis from the lower edge portion 100a2. The bottom plate portion 190 faces the lower frame member 400 in the Y-axis direction. The bottom plate portion 190 is disposed below the lower frame member 400. The bottom plate portion 190 is fixed to the lower frame member 400 by screws BT that are inserted in the Y-axis direction.

[0027] Meanwhile, an upper edge portion 100a1 of the first panel 100 is fixed to an upper frame member 300. The upper frame member 300 is an example of a frame member according to the present disclosure. Screws BT are not used to fix the upper edge portion 100a1 of the first panel 100 to the upper frame member 300. This point will be described in detail below.

[0028] The upper frame member 300 is provided with an engaged portion 611. Meanwhile, the upper edge portion 100a1 of the first panel 100 is provided with an engaging portion 612 that engages with the engaged portion 611. The engaged portion 611 has a recess 380, and the engaging portion 612 has an insertion portion 180 that is inserted into the recess 380.

[0029] Then, by inserting the insertion portion 180 into the recess 380, the upper edge portion 100a1 of the first panel 100 is fixed to the upper frame member 300. Moreover, by removing the insertion portion 180 from the recess 380, this fixation is released.

[0030] In this way, the engaged portion 611 and the engaging portion 612 allow the upper edge portion 100a1 of the first panel 100 to be fixed to and released from the upper frame member 300 without using the screw BT. Therefore, compared to when the screw BT is also used to fix the upper edge portion 100a1 of the first panel 100, the first panel 100 can be easily attached to and detached from the framework 500 during maintenance, inspection, etc.

[0031] Furthermore, since there is no need to use screws BT, lock handles, etc. to fix the upper edge portion 100a1 of the first panel 100 to the upper frame member 300, there is no need to expose the screws BT, lock handles, etc. on the surface 100a of the first panel 100. This contributes to improving the aesthetic appearance of the door pocket 610 and preventing tampering with the door pocket 610.

[0032] The screws BT that secure the lower edge portion 100a2 of the first panel 100 to the lower frame member 400 are disposed at the bottom of the door pocket 610 that faces the platform PF. In other words, the screws BT are not exposed to the eyes of passengers. Therefore, the screws BT are unlikely to spoil the aesthetic appearance of the door pocket 610, and are also unlikely to be used for mischief.

[0033] The configurations of the engaged portion 611 and the engaging portion 612, each extending in the Z-axis direction, will be described in detail below. First, the configuration of the engaging portion 612 will be described with reference to FIG.

[0034] 3, the engagement portion 612 has the aforementioned insertion portion 180 and a base portion 110 that connects the insertion portion 180 to the upper edge portion 100a1 of the first panel 100. The insertion portion 180 and the base portion 110 extend in the Z-axis direction along the upper edge portion 100a1 of the first panel 100.

[0035] The base portion 110 extends in the positive direction of the X-axis from an upper edge portion 100a1 of the first panel 100, which extends parallel to the YZ plane.

[0036] The insertion portion 180 stands up from the base portion 110. The insertion portion 180 has a root portion 120 connected to the base portion 110 and an extension portion 130 extending from the root portion 120. The extension portion 130 forms a tip 130a of the insertion portion 180.

[0037] When the insertion portion 180 is inserted into the recess 380 described above, the base portion 120 is located at the entrance of the recess 380 , and the extension portion 130 is located deeper in the recess 380 than the base portion 120 .

[0038] Specifically, the root portion 120 rises from the base portion 110 in the positive direction of the Y axis. The extension portion 130 extends at an angle relative to the extension direction of the root portion 120, i.e., the Y axis direction, in a direction approaching the orbital space SB shown in Fig. 2. Therefore, the tip 130a of the extension portion 130 is disposed inward, farther from the surface 100a of the first panel 100 than the root portion 120, in the X axis direction.

[0039] Next, the configuration of the engaged portion 611 will be described with reference to FIG.

[0040] 4, the engaged portion 611 has the recess 380 described above and a base surface 310 located on the edge of an opening 381 of the recess 380. The recess 380 has a depth in a direction intersecting an XZ plane, which is an imaginary plane parallel to the X-axis direction and the Z-axis direction, which is the extension direction of the upper frame member 300, specifically in the Y-axis direction. More specifically, the recess 380 is recessed in the positive direction of the Y-axis relative to the base surface 310.

[0041] The base surface 310 is located at the edge of the opening 381 of the recess 380 that is closer to the surface 100a of the first panel 100 in the X-axis direction. The recess 380 and the base surface 310 extend in the Z-axis direction along the upper edge portion 100a1 of the first panel 100.

[0042] Recess 380 has narrowed portion 320 which constitutes the entrance portion of recess 380, and inner portion 330 which constitutes the portion of recess 380 deeper than narrowed portion 320. Narrowed portion 320 defines an opening 381.

[0043] The inner surface of the narrowed portion 320 has a first inner inlet surface portion 321 and a second inner inlet surface portion 322 that face each other in the X-axis direction with a gap that defines the opening 381. The first inner inlet surface portion 321 rises from the above-mentioned base surface 310. The second inner inlet surface portion 322 is located further inward than the first inner inlet surface portion 321 from the front surface 100a of the first panel 100 in the X-axis direction.

[0044] The inner dimension of the deepest portion 330 in the X-axis direction is larger than the inner dimension of the narrowed portion 320 in the X-axis direction. The inner surface of the deepest portion 330 has a bottom portion 333 located at the deepest part of the recess 380, and a first side surface portion 331 and a second side surface portion 332 connecting the bottom portion 333 and the narrowed portion 320. The first side surface portion 331 and the second side surface portion 332 face each other in the X-axis direction. The bottom portion 333 connects the first side surface portion 331 and the second side surface portion 332.

[0045] In this embodiment, bottom portion 333 extends parallel to the XZ plane perpendicular to the Y-axis direction. Furthermore, first side surface portion 331 and second side surface portion 332 extend parallel to the YZ plane perpendicular to the X-axis direction. An inside corner (hereinafter referred to as a deep inside inside corner portion) 334 formed at the boundary between bottom portion 333 and second side surface portion 332 is an example of a deep inside inside surface portion against which tip end 130a of insertion portion 180 described above abuts.

[0046] Hereinafter, a method for inserting the insertion portion 180 into the recess 380 will be described with reference to FIG.

[0047] 5, first, the first panel 100 is brought diagonally in the positive direction toward the upper frame member 300. This causes the tip 130a of the insertion portion 180 to pass through the opening 381 of the recess 380 and come into contact with the second side surface portion 332.

[0048] Here, the "diagonal positive direction" refers to the direction indicated by a vector expressed as the sum of a vector in the positive direction of the X axis and a vector in the positive direction of the Y axis. The concept of a diagonal positive direction includes the direction in which the extension portion 130 extends from the base portion 120.

[0049] Next, the first panel 100 is brought closer to the upper frame member 300 in the positive direction of the Y axis. Then, when the base portion 110 of the first panel 100 abuts against the base surface 310 at the edge of the opening 381 of the recess 380, the insertion of the insertion portion 180 into the recess 380 is completed.

[0050] The insertion portion 180 can be removed from the recess 380 by reversing the above-described procedure. A specific explanation will be given below. In the following explanation, the "diagonal negative direction" refers to the direction indicated by a vector expressed as the sum of a vector in the negative X-axis direction and a vector in the negative Y-axis direction.

[0051] First, the first panel 100 is moved in the negative Y-axis direction away from the upper frame member 300. This causes the base portion 120 of the insertion portion 180 to come out of the recess 380.

[0052] Next, the first panel 100 is moved diagonally in the negative direction away from the upper frame member 300. This causes the extension portion 130 of the insertion portion 180 to come out of the recess 380. This completes the process of removing the insertion portion 180 from the recess 380.

[0053] 6 shows a state in which insertion of insertion portion 180 into recess 380 is complete. When insertion is complete, root portion 120 abuts against first inlet inner surface portion 321, tip end 130a of extension portion 130 abuts against rear inner corner portion 334, and base portion 110 abuts against base surface 310.

[0054] When tip 130a of extension portion 130 abuts against rear inner corner portion 334, displacement of first panel 100 in the positive X-axis direction, which is the direction in which the force with which tip 130a presses against rear inner corner portion 334, increases, is suppressed. Furthermore, when root portion 120 abuts against first inlet inner surface portion 321, displacement of first panel 100 in the negative X-axis direction, which is the direction in which the force with which root portion 120 presses against first inlet inner surface portion 321 increases, is also suppressed. As a result, rattle of first panel 100 in the X-axis direction is suppressed.

[0055] Furthermore, by having the base portion 110 come into contact with the base surface 310, displacement of the first panel 100 in the positive Y-axis direction, which is the direction in which the force with which the base portion 110 presses the base surface 310 increases, is suppressed. Displacement of the first panel 100 in the negative Y-axis direction is suppressed by the screws BT shown in Figure 2. As a result, rattle of the first panel 100 in the Y-axis direction is suppressed.

[0056] As described above, the position at which tip 130a of extension portion 130 abuts is deep inner corner portion 334. Therefore, when insertion portion 180 is inserted into recess 380, not only is displacement of tip 130a prevented in the positive X-axis direction, but displacement of tip 130a toward the back of recess 380, specifically in the positive Y-axis direction, is also prevented. To illustrate the significance of this, reference form 1 will be described below.

[0057] 7 shows a configuration according to Reference Mode 1. In Reference Mode 1, when the insertion of the insertion portion 180 into the recess 380 is complete, the position with which the tip 130a of the extension portion 130 abuts is the second side surface portion 332.

[0058] Even in this case, since the tip 130a of the extension portion 130 abuts against the second side surface portion 332, even if a pushing force F in the positive X-axis direction acts on the first panel 100, displacement of the first panel 100 in the positive X-axis direction is suppressed.

[0059] However, if the pushing force F is strong enough to deflect the insertion portion 180, the tip 130a of the extension portion 130 slides in the positive direction of the Y axis along the second side surface portion 332 while remaining in contact with the second side surface portion 332, and at the same time, the insertion portion 180 deflects. As a result, the root portion 120 moves away from the first inlet inner surface portion 321, and the first panel 100 is easily displaced in the positive direction of the X axis.

[0060] The reason for this phenomenon is that the extending portion 130 extends in an oblique direction inclined relative to the X-axis and Y-axis directions. In other words, because the extending portion 130 extends in an oblique direction, the force with which the tip 130a of the extending portion 130 presses the second side surface portion 332 has not only a component force component in the positive direction of the X-axis, but also a component force component in the positive direction of the Y-axis. The component force component in the positive direction of the Y-axis causes the sliding described above.

[0061] After sliding along the second side surface portion 332 in the positive direction of the Y axis, when the tip 130a of the extension portion 130 hits the rear inner corner portion 334, the tip 130a of the extension portion 130 is prevented from sliding in the positive direction of the Y axis. At this time, the first panel 100 is prevented from being displaced in the positive direction of the X axis for the first time.

[0062] In contrast, in the configuration according to this embodiment, as shown in Fig. 6, when the insertion of the insertion portion 180 into the recess 380 is completed, the tip 130a of the extension portion 130 has already come into contact with the rear inner corner portion 334. Therefore, displacement of the tip 130a in the positive direction of the Y axis is also prevented, and sliding of the tip 130a in the positive direction of the Y axis does not occur.

[0063] For this reason, with the configuration according to this embodiment, first panel 100 is less likely to be displaced in the positive direction along the X axis than with the configuration according to Reference Form 1. As described above, preventing displacement of tip 130a in the positive direction along the Y axis is significant in that it enhances the effect of suppressing displacement of first panel 100 in the positive direction along the X axis.

[0064] Next, a second embodiment will be described to illustrate other features of this embodiment.

[0065] Fig. 8 shows a configuration according to Reference Form 2. In Reference Form 1, the width of opening 381 of recess 380 in the X-axis direction is narrower than in the embodiment shown in Fig. 6. For this reason, when inserting extension portion 130 of insertion portion 180 into narrow portion 320 of recess 380, it is necessary to rotate the entire first panel 100 by a certain angle φ around the Z axis and bring it closer to upper frame member 300 in a diagonal positive direction.

[0066] Unless the entire first panel 100 is rotated by the angle φ, the tip 130a of the extension portion 130 will hit the second inlet inner surface portion 322, preventing the extension portion 130 from passing through the opening 381. Similarly, when removing the insertion portion 180 from the recess 380, the entire first panel 100 must be rotated by the angle φ.

[0067] The operation of rotating the entire first panel 100 by the angle φ can be a factor that hinders the simplification of attaching and detaching the first panel 100. Below, we return to the description of the configuration of this embodiment that solves this problem.

[0068] 6, the width of opening 381 of recess 380 in the X-axis direction, i.e., the distance in the X-axis direction between first inlet inner surface portion 321 and second inlet inner surface portion 322, is defined as A. Also, the dimension of second inlet inner surface portion 322 in the Y-axis direction is defined as B. Also, the inclination angle of extension portion 130 with respect to the Y-axis direction is defined as θ.

[0069] This embodiment employs a configuration that satisfies arctan(A / B)≧θ. As a result, as shown in Fig. 5, tip 130a of insertion portion 180 can be passed through opening 381 of recess 380 and brought into contact with second side surface portion 332 while keeping surface 100a of first panel 100 parallel to the YZ plane.

[0070] After tip 130a of insertion portion 180 hits second side surface portion 332, the insertion of insertion portion 180 into recess 380 can be completed by moving first panel 100 in the positive direction of the Y axis while keeping surface 100a of first panel 100 parallel to the YZ plane. In other words, there is no need to rotate first panel 100 about the Z axis during the insertion process.

[0071] Furthermore, after inserting portion 180 has been completely inserted into recess 380, it is possible to move it in the negative Y-axis direction until extending portion 130 abuts narrowed portion 320, and then, while keeping surface 100a of first panel 100 parallel to the YZ plane, extend- ing portion 130 can be removed from narrowed portion 320. In other words, there is no need to rotate first panel 100 about the Z-axis during the removal process.

[0072] As described above, according to this embodiment, by adopting a configuration that satisfies arctan(A / B)≧θ, it is not necessary to rotate the entire first panel 100 about the Z axis when inserting the insertion portion 180 into the recess 380 or removing the insertion portion 180 from the recess 380. Therefore, compared to the configuration according to the second embodiment, the first panel 100 can be attached and detached more easily and quickly.

[0073] [Embodiment 2] 2 shows an example of a configuration in which the first panel 100 facing the passenger waiting space SA can be easily attached and detached. A configuration in which the second panel 200 facing the on-track space SB can be easily attached and detached may also be adopted. This will be explained in detail below.

[0074] 9 shows a configuration that simplifies attachment and detachment of the second panel 200. That is, in this embodiment, the second panel 200 is an example of a panel according to the present disclosure. Therefore, in this embodiment, the direction from the second panel 200 toward the first panel 100 is defined as the positive direction of the X axis. In this case, the positive direction of the Z axis is opposite to the definition shown in FIG. 2.

[0075] In this embodiment, an engaging portion 612 is provided on an upper edge portion 200a1 of the surface 200a of the second panel 200. An engaged portion 611 that engages with the engaging portion 612 is provided on the upper frame member 300. Also, as in the case of embodiment 1, a lower edge portion 200a2 of the surface 200a of the second panel 200 is fixed to the lower frame member 400 by a screw BT.

[0076] The configurations and operations of the engaging portion 612 and the engaged portion 611 according to this embodiment are the same as those in the first embodiment, and according to this embodiment, the second panel 200 can be easily attached and detached during maintenance, inspection, etc. Note that by combining the first and second embodiments, it is possible to simplify the attachment and detachment of both the first panel 100 and the second panel 200.

[0077] [Embodiment 3] FIG. 2 illustrates a configuration in which the upper frame member 300 is provided with an engaged portion 611, and the first panel 100 is provided with an engaging portion 612 on the upper edge portion 100a1.

[0078] As shown in FIG. 10, in this embodiment, an engaged portion 611 is provided on the upper edge portion 100a1 of the first panel 100, and an engaging portion 612 is provided on the upper frame member 300.

[0079] In this embodiment as well, the edge portion 100a1 of the first panel 100 is fixed to the upper frame member 300 by inserting the insertion portion 180 of the engaging portion 612 into the recess 380 of the engaged portion 611. This fixation is released by removing the insertion portion 180 from the recess 380. This makes it easy to attach and detach the first panel 100 for maintenance, inspection, and the like.

[0080] Furthermore, displacement of first panel 100 in the positive direction along the X axis is suppressed by tip 130a of insertion portion 180 abutting against rear inner corner portion 334. Displacement of first panel 100 in the negative direction along the X axis is suppressed by root portion 120 abutting against first inlet inner surface portion 321. Therefore, rattling of first panel 100 in the X axis direction is suppressed.

[0081] Furthermore, displacement of the first panel 100 in the positive direction of the Y axis is suppressed by the base portion 110 abutting against the base surface 310. Displacement of the first panel 100 in the negative direction of the Y axis is suppressed by the screws BT shown in Figure 2. Therefore, rattle of the first panel 100 in the Y axis direction is also suppressed.

The shape of a cross section of the depth 330 perpendicular to the Z-axis direction is not particularly limited to a rectangle.

[0083] 11, the inner surface of the back portion 330 according to this embodiment has a curved surface that is convex in the direction from the narrowed portion 320 toward the back of the recessed portion 380, i.e., in the positive Y-axis direction. The recessed portion 380 has the narrowed portion 320, which is the same as the configuration according to the first embodiment shown in FIG. This embodiment also provides the same effects as the first embodiment.

[0084] [Embodiment 5] In the first to fourth embodiments, the engaged portion 611 may be formed by attaching a narrow portion-forming member that forms the narrow portion 320 and the base surface 310 to a deep portion-forming portion where the deep portion 330 of the recess 380 is formed. An example will be described below.

[0085] As shown in FIG. 12, the engaged portion 611 according to this embodiment is formed by attaching two plate-like members 300b, each extending in the Z-axis direction, to the main body portion 300a of the upper frame member 300.

[0086] The main body 300a of the upper frame member 300 is an example of a deep portion forming portion in which the deep portion 330 of the recess 380 is formed. The two plate-like members 300b are an example of narrow portion forming members that form the narrow portion 320. One of the plate-like members 300b forms the base surface 310 and the first inlet inner surface portion 321. The other plate-like member 300b forms the second inlet inner surface portion 322.

[0087] According to this embodiment, the recess 380 having the innermost portion 330 and the narrowed portion 320 and the base surface 310 can be easily formed.

[0088] The above describes embodiments 1 to 5. The following variations are also possible.
