Summary of the Invention

Problems to be Solved by the Invention

[0005] In the platform fence of Patent Document 1, the inspection panel (40) that serves as a sliding door for emergency escape is a large structure that slides across two movable door driving parts (30, 31). Therefore, the opening that becomes the emergency exit starts to open after sliding a distance corresponding to one of the two movable door driving parts. In addition, a long-distance sliding movement is necessary to fully open the emergency exit. Also, because the total length in the longitudinal direction of the platform is long, the inspection panel (40) has a corresponding weight, and a large force may be required for those who want to open the emergency exit. necessary. Also, because the total length in the longitudinal direction of the platform is long, the inspection panel (40) has a corresponding weight, and a large force may be required for those who want to open the emergency exit.

[0006] The problem that this invention aims to solve is to provide a technology that enables the structure of an emergency exit in a sliding platform safety barrier with an emergency exit to be realized in a simpler and more rational structure than in conventional designs. [Means for solving the problem]

[0007] The first invention for solving the above problems is a platform fence comprising a door pocket and a door, wherein the door pocket comprises a sliding panel portion and a fixed panel portion that slidably supports the door portion in the longitudinal direction of the platform and slidably supports the sliding panel portion between a normal position and an emergency position in the longitudinal direction of the platform, the sliding panel portion comprises a platform-side cover portion whose length in the longitudinal direction of the platform is longer than that of the fixed panel portion and which is located on the platform side of the fixed panel portion at both the normal position and the emergency position, and an upper cover portion of the sliding panel, the fixed panel portion comprises an upper cover portion of the fixed panel, and the upper cover portion of the sliding panel and the upper cover portion of the fixed panel do not interfere with each other in the sliding movement of the sliding panel portion, and the upper cover portion of the fixed panel is exposed upward at both the normal position and the emergency position of the sliding panel portion, thus having a cover non-interference structure.

[0008] According to the first invention, the sliding panel section is supported by a single support structure called the fixed panel section, and when slid in an emergency, the opening as an emergency exit begins to open immediately, resulting in a simple and rational structure.

[0009] Furthermore, the sliding panel section functions not only as an emergency door but also as the exterior of the door pocket section. Specifically, the platform-side cover section of the sliding panel section covers the platform-side of the door pocket section, and the upper sliding panel cover section of the sliding panel section covers the upper part of the door pocket section. The length of the sliding panel section in the longitudinal direction of the platform is longer than that of the fixed panel section, and in both the normal and emergency positions it is located on the platform side of the fixed panel section, so it covers the platform side of the fixed panel section in both normal and emergency situations. Even in an emergency, the interior of the fixed panel section is not exposed to the platform side, and the design of the door pocket section as seen from the platform side is not compromised even in an emergency.

[0010] In addition, due to the cover's non-interference structure, the upper cover portion of the fixed panel is exposed upwards in both normal and emergency situations, so the internal structure of the fixed panel portion is not exposed even in an emergency.

[0011] The second invention is a platform safety barrier in which the cover non-interference structure is such that the upper cover portion of the fixed panel is positioned above the upper cover portion of the sliding panel, and the upper cover portion of the sliding panel slides below the upper cover portion of the fixed panel.

[0012] According to the second invention, the upper part of the fixed panel is double-covered by the fixed panel upper cover and the slide panel upper cover. It can also be described as a double structure in which the slide panel upper cover extends below the fixed panel upper cover.

[0013] The third invention is a platform safety barrier in which the upper cover portion of the fixed panel is connected to the fixed panel portion on the track side, and the upper cover portion of the sliding panel is connected to the sliding panel portion on the platform side.

[0014] According to the third invention, a double structure consisting of a fixed panel upper cover and a sliding panel upper cover can be realized.

[0015] The fourth invention is a platform safety barrier in which the cover non-interference structure is such that the upper cover portion of the slide panel is supported on the slide panel so as to be vertically rotatable, and is displaceable between an interference position in which it interferes with the upper cover portion of the fixed panel and a non-interference position in which it does not interfere during sliding movement.

[0016] According to the fourth invention, the slide panel can be made to slide by rotating the upper cover portion of the slide panel to a non-interference position. In other words, it becomes possible to switch between normal operation, when the emergency exit is not in use, and emergency operation, when the emergency exit is in use, with a simple operation of rotating the upper cover portion of the slide panel.

[0017] The fifth invention is a platform safety barrier in which, when the upper cover portion of the sliding panel is located at the interference position, the upper cover portion of the fixed panel and the upper cover portion of the sliding panel are in a predetermined height relationship having a design in which the upper surface shapes are continuous.

[0018] According to the fifth invention, by aligning the heights of the upper cover portion of the sliding panel and the upper cover portion of the fixed panel, a cover non-interference structure that looks good at the top of the door pocket can be realized under normal conditions.

Embodiments for Carrying Out the Invention

[0020] Hereinafter, embodiments of the circuit controller to which the present invention is applied will be described. Needless to say, the forms to which the present invention can be applied are not limited to the following embodiments. In each drawing, a right-handed orthogonal three-axis (X-axis, Y-axis, Z-axis) indicating a common direction is shown. The XY plane represents a plane parallel to the upper surface of the platform. The positive X-axis direction indicates the track side, and the negative X-axis direction indicates the home side. The positive Y-axis direction indicates the right side as seen from the track side, and the positive Z-axis direction indicates the upward direction.

[0021] 〔First Embodiment〕 FIG. 1 is an external view of the home barrier 2 of the first embodiment as seen from the track side, showing the normal state in which the boarding and alighting openings are fully closed. FIG. 2 is a side view of the home barrier 2 as seen from the negative Y-axis direction. FIG. 3 is an external view of the home barrier 2 as seen from the track side, showing the state in which the emergency opening is open.

[0022] The home barrier 2 includes a door pocket portion 10 and a door portion 20. The door pocket portion 10 is erected and fixed at the track-side end of the platform 3 of the station, supports the door portion 20 so as to be slidable along the home longitudinal direction (the left-right direction and the Y-axis direction in FIG. 1) of the platform 3, and advances / retracts it to open and close the boarding and alighting openings to the train.

[0023] The door pocket portion 10 has a first support portion 11 that supports and moves the first door portion 21 forward and backward, a second support portion 12 that supports and moves the second door portion 22 forward and backward, and a slide panel portion 50 that is supported so as to be slidable along the home longitudinal direction (Y-axis direction) on the home side of the first support portion 11.

[0024] The first support portion 11 and the second support portion 12 are fixed in a straight line along the longitudinal direction (Y-axis direction) of the door pocket portion 10, separated by a predetermined distance Le that includes the space designated as an emergency exit (see Figure 3) in an emergency.

[0025] In the normal state shown in Figure 1, the slide panel section 50 is in the normal position that blocks the platform side of the gap Le, and its end on the positive Y-axis side is locked to the second support section 12 by the locking section 7. The locking section 7 can be locked / unlocked from the track side. In an emergency, the locking is released by unlocking the locking section 7, allowing the slide panel section 50 to slide. Then, by sliding the slide panel section 50 toward the first support section 11 (negative Y-axis direction) to the emergency position shown in Figure 3, the area from the gap Le excluding the remaining portion (the area of ​​the emergency exit shown by the double arrow in Figure 3) becomes an emergency exit.

[0026] This section explains the detailed structure of platform screen door 2. The first support section 11 is a fixed panel section 19 that supports the first door section 21 so as to be slidable in the longitudinal direction of the platform, and supports the sliding panel section 50 so as to be slidable between a normal position and an emergency position in the longitudinal direction of the platform.

[0027] Specifically, as shown in Figure 1, the first support section 11 incorporates a sway-preventing guide 14 for the first door section 21 at its upper part, and incorporates a linear guide 15 that slidably supports the first door section 21 and a drive unit 30 that moves the first door section 21 forward and backward at its lower part.

[0028] The drive unit 30 is a belt-type drive unit in which, for example, a toothed belt 31 stretched over the lower end of the first door section 21 is placed on a drive pulley 33 driven by the drive mechanism section 32, and appropriate tension is applied by a driven pulley 34. The drive mechanism section 32 includes an electric motor, a reduction gearbox, a control board, etc. The drive unit 30 receives an opening / closing signal for the platform gate 2 from the outside and drives the electric motor in forward / reverse direction to advance the first door section 21 from the first support section 11 to close the platform gate 2, or to retract it to the storage position to open the platform gate 2. Note that the drive method of the drive unit 30 is not limited to a belt type.

[0029] As shown in Figure 2, the upper part of the fixed panel section 19 is covered by the fixed panel upper cover section 41. In addition, the three sides of the fixed panel section 19—the side on the Y-axis positive direction, the side on the X-axis positive direction (trajectory side), and the side on the Y-axis negative direction—are covered by the side cover section 42. The upper cover portion 41 of the fixed panel may be integrated with the side cover portion 42 or it may be a separate part. The side cover portion 42 may be configured to cover three sides—the side on the negative Y-axis direction, the side on the positive X-axis direction (trajectory side), and the side on the positive Y-axis direction—with a single part, or it may be configured to cover multiple parts.

[0030] The upper cover portion 41 of the fixed panel has an upright portion that rises upward from the track-side portion of the side cover portion 42, and has a curved shape that covers the upper part of the fixed panel portion 19 in a mountain-like manner toward the platform side from this upright portion. When the upper cover portion 41 of the fixed panel is viewed from the negative Y-axis direction, it has a two-slope shape in which a sloping surface that slopes downward toward the platform side and a sloping surface that slopes downward toward the track side are connected.

[0031] The first support section 11 has a linear guide 16 for the slide panel section 50 and supports the slide panel section 50 so that it can slide freely between a normal position (the position shown in Figure 1) and an emergency position (the position shown in Figure 3) in the longitudinal direction of the home (Y-axis direction).

[0032] The linear guide 16 is composed of, for example, an upper linear guide 16a provided on the upper part of the first support section 11 and a lower linear guide 16b provided on the lower end of the first support section 11 on the platform side. However, the mounting position and number of the linear guides 16 are not limited to these. For example, the linear guides 16 may be provided on the platform side of the first support section 11.

[0033] The sliding panel section 50 is an emergency door element that closes the platform side of the gap Le which serves as an emergency exit, and also an exterior element that covers the platform side of the first support section 11. Specifically, the sliding panel section 50 has a platform side cover section 51 and an upper sliding panel cover section 52.

[0034] The platform-side cover portion 51 is a plate-like portion that, in its normal position, integrally covers the platform side of the fixed panel portion 19 and the platform side at the gap Le. The lower end of the platform-side cover portion 51 is slidably supported by the lower linear guide 16b.

[0035] The length of the slide panel section 50 in the longitudinal direction of the platform (length in the Y-axis direction) is set to a length equivalent to the length of the first support section 11 in the longitudinal direction of the platform plus the interval Le. Therefore, the platform-side cover section 51 has a length in the longitudinal direction of the platform that is longer than the first support section 11 (fixed panel section 19), and is located on the platform side of the fixed panel section 19 in both the normal position and the emergency position.

[0036] The upper cover portion 52 of the slide panel also serves as an element that covers the area above the gap Le in the normal position. Specifically, the length of the upper cover portion 52 of the slide panel in the longitudinal direction of the platform is the same as that of the platform-side cover portion 51. Furthermore, when viewed from the side from the negative Y-axis direction, the upper surface shape of the upper cover portion 52 of the slide panel has a two-slope shape that is substantially similar to the upper surface shape of the upper cover portion 41 of the fixed panel. The lower surface of the upper cover portion 52 of the slide panel is slidably supported by the upper linear guide 16a.

[0037] The upper cover portion 52 of the slide panel is located lower than the upper cover portion 41 of the fixed panel, and whether the slide panel portion 50 is in the normal position or the emergency position, a part of the upper cover portion 52 of the slide panel is always positioned below the upper cover portion 41 of the fixed panel. In other words, the upper cover portion 52 of the slide panel and the upper cover portion 41 of the fixed panel do not interfere with each other during the sliding movement of the slide panel portion 50, and the upper cover portion 41 of the fixed panel is exposed above in both the normal position and the emergency position of the slide panel portion 50, thus forming a cover non-interference structure.

[0038] The second door section 22 has a structure that is a left-right inversion of the first door section 21.

[0039] The second support section 12 incorporates a sway-preventing guide 14 for the second door section 22 at its upper part, and a linear guide 15 at its lower part that supports the second door section 22 so as to be slidable in the longitudinal direction of the platform, as well as a drive unit 30 that moves the second door section 22 forward and backward. However, the second support section 12 does not have a slide panel section 50 or any related components.

[0040] The second support section 12 is covered on the outside by an upper cover section 43 and a full-circumference cover section 44. The upper cover section 43 covers the top of the second support section 12. When viewed from the side from the negative Y-axis direction, the upper surface shape of the upper cover section 43 has two slopes that are substantially similar to the upper surface shape of the upper cover section 41 of the fixed panel of the first support section 11. The full-circumference cover section 44 covers four sides: the side on the positive Y-axis direction, the side on the positive X-axis direction (track side), the side on the negative Y-axis direction, and the side on the negative X-axis direction (home side).

[0041] The height of the second support section 12 is the same as that of the first support section 11. The length of the second support section 12 in the longitudinal direction of the home (length in the Y-axis direction) is the same as that of the first support section 11.

[0042] Therefore, the overall appearance of the door pocket section 10 in normal conditions (when the emergency exit is closed) will be a single, box-shaped structure. The upper surface of the door pocket section 10 consists of the upper cover section 41 of the fixed panel of the first support section 11, the upper cover section 52 of the sliding panel section 50, and the upper cover section 43 of the second support section 12, which are arranged in a stepped manner in a straight line along the length of the platform. Passengers on the platform side will see a straight line with two sloping shapes, and the gap Le will be hidden and not visible.

[0043] I will now explain how to open the emergency exit. In an emergency, anyone attempting to open the emergency exit unlocks the locking mechanism 7 from the track side. They then slide the sliding panel 50 in the direction of the first support 11 (to the left in Figure 3; negative Y-axis direction). As soon as the panel is slid, the opening that forms the emergency exit, secured by the gap Le, begins to open. By sliding the sliding panel 50 to the emergency position, the emergency exit is fully opened. During this time, the fixed panel upper cover 41 is positioned above the sliding panel upper cover 52, and the sliding panel upper cover 52 slides below the fixed panel upper cover 41. As shown by the double arrows in Figure 3, the area from the gap Le (see Figure 1) excluding the remaining portion functions as the "emergency exit".

[0044] As described above, according to this embodiment, in a sliding platform safety barrier with an emergency exit, the structure related to the emergency exit can be realized with a simpler and more rational structure than in the conventional design.

[0045] In other words, the sliding panel section 50 that closes the gap Le which serves as an emergency exit is supported solely by the first support section 11 and not by the second support section 12. The sliding panel section 50 is structured so that when it is slid in an emergency, the opening for the emergency exit begins to open immediately.

[0046] Furthermore, the sliding panel section 50 also serves as an exterior element covering the platform side of the first support section 11. In both the normal and emergency positions, it is located closer to the platform than the first support section 11 (fixed panel section 19), and covers the platform side of the first support section 11 and the gap Le with one surface. Therefore, even in an emergency, the interior of the first support section 11 will not be exposed to the platform side.

[0047] In addition, due to the cover non-interference structure, the upper cover portion 41 of the fixed panel is exposed upwards in both normal and emergency situations, so the internal structure of the first support portion 11 (fixed panel portion 19) is not exposed upwards even in an emergency.

[0048] Furthermore, the upper part of the first support section 11 is double-covered by the upper cover section 52 of the slide panel section 50 and the upper cover section 41 of the fixed panel. This double-layered structure makes it possible for anyone attempting to open the emergency exit to intuitively understand how to do so.

[0049] Specifically, the structure in which the sliding panel upper cover portion 52 is tucked inside the fixed panel upper cover portion 41 can be easily understood visually, so that anyone attempting to open an emergency exit can understand at a glance whether to move the sliding panel portion 50 to the left or right.

[0050] Of course, when putting the platform screen door 2 into practical use, the operation method of the slide panel section 50 will need to be indicated in some way (for example, on the track-side surface of the platform-side cover section 51, there will be an explanation of the operation method and a diagram showing the direction of movement of the slide panel section 50). However, with the structure of this embodiment, the double structure, which is naturally visible when trying to operate the slide panel section 50 to open the emergency exit, makes it possible for the person trying to open the emergency exit to intuitively understand how to open it.

[0051] [Second Embodiment] Next, a second embodiment will be described. However, the same reference numerals will be used for components similar to those in the first embodiment, and redundant explanations will be omitted. The focus will be on the differences from the first embodiment.

[0052] Figure 4 is an external view of the platform screen door 2B of the second embodiment as seen from the track side, showing the boarding / alighting opening fully closed under normal conditions. Figure 5 is a side view of the platform screen door 2B of Figure 4 as seen from the negative Y-axis direction. Figure 6 is a longitudinal cross-sectional view of the platform screen door 2B of Figure 4 as seen from the negative Y-axis direction along the VI-VI section.

[0053] As shown in Figure 5, the upper surface shape of the door pocket portion 10 of the platform fence 2B, when viewed from the side in the negative Y-axis direction, has a two-slope shape similar to the first embodiment, with a slope descending towards the platform and a slope descending towards the track. However, the slope descending towards the platform is divided.

[0054] Specifically, the upper cover portion 41B of the fixed panel of the platform fence 2B has a slope 45 that slopes downward toward the track and an upper divided slope 46 that slopes downward toward the platform. The upper divided slope 46 forms part of the platform-side slope of the door pocket portion 10 and is interrupted midway up the upper part of the platform-side slope. The portion of the slope that slopes downward from the point of interruption is formed by the upper surface of the slide panel portion 50B.

[0055] The upper surface of the slide panel section 50B has a downward dividing inclined surface 53 that slopes downward toward the platform side along its entire length in the longitudinal direction of the platform. The inclination angle of the downward dividing inclined surface 53 is the same as that of the upper dividing inclined surface 46 of the fixed panel upper cover section 41B, and these dividing inclined surfaces are set to appear as a single continuous inclined surface when viewed from the side in the negative Y-axis direction.

[0056] The upper part of the sliding panel section 50B is connected to the upper part of the rotating sliding panel upper cover section 52B by a hinge 58. The total length of the rotating sliding panel upper cover section 52B is limited to the range of the interval Le.

[0057] As shown in Figure 6, the upper surface shape of the rotating slide panel upper cover portion 52B, viewed from the negative Y-axis direction, is a two-slope shape with a slope descending towards the platform side and a slope descending towards the track side, corresponding to the upper surface shape of the fixed panel upper cover portion 41B.

[0058] The hinge 58 has a rotation axis in the longitudinal direction of the home (Y-axis direction). Therefore, the upper cover portion 52B of the rotating slide panel is rotatably supported so that it can be flipped upward and tilted toward the home side using the axis of the hinge 58 as the pivot axis.

[0059] As shown in Figure 4, when the slide panel section 50 is in its normal position, the upper cover section 52B of the rotating slide panel is contained within the gap Le. The upper cover section 41B of the fixed panel of the first support section 11, the upper cover section 52B of the rotating slide panel, and the upper cover section 43 of the second support section are aligned in height and top surface shape. In other words, these three cover sections have a predetermined height relationship that creates a continuous design of top surface shapes, and the upper surface of the door pocket section 10 appears to form a continuous roof shape.

[0060] Focusing on the non-interference structure of the platform screen door 2B, the upper cover portion 52B of the rotating slide panel is supported by the slide panel portion 50B so as to be able to rotate up and down. This structure allows for displacement between an interference position where it interferes with the upper cover portion 41B of the fixed panel and a non-interference position where it does not interfere during sliding movement.

[0061] Figure 7 is an external view of platform screen door 2B as seen from the track side, showing the emergency exit in the open position. Figure 8 is a side view of platform barrier 2B in Figure 7, viewed from the negative Y-axis direction.

[0062] In an emergency, anyone attempting to open the emergency exit unlocks the locking mechanism 7 from the track side. Next, they push up the upper cover portion 52B of the rotating slide panel and tilt it toward the platform. This displaces the upper cover portion 52B of the rotating slide panel to a non-interference position where it does not interfere with the upper cover portion 41B of the fixed panel during sliding. Next, anyone attempting to open the emergency exit slides the slide panel portion 50B toward the first support portion 11 (to the left in Figure 7; negative Y-axis direction). As soon as it slides, the opening that forms the emergency exit, secured by the gap Le, begins to open. By sliding the slide panel portion 50B to the emergency position, the emergency exit is fully opened. During the sliding motion, the upper cover portion 52B of the rotating slide panel does not come into contact with the upper cover portion 41B of the fixed panel, maintaining a state where the upper cover portion 41B of the fixed panel is exposed above.

[0063] According to platform screen door 2B, switching between normal use when the emergency exit is not in use and emergency use when the emergency exit is in use can be achieved with a simple operation: rotating the upper cover section 52B of the rotating slide panel.

[0064] [Variation] Furthermore, the applicable embodiments of the present invention are not limited to those described above, and components can be added, omitted, or modified as appropriate.

[0065] For example, although the upper surface shape of the door pocket section 10 was described as a two-slope shape like a gable roof, it may be a single-slope roof shape consisting of one sloping surface, or it may be a shape with a flat surface in part, or a curved shape.

[0066] Alternatively, a single platform screen door 2,2B may be constructed by omitting the second support section 12 and the second door section 22.

[0067] Furthermore, in the second embodiment, when the upper cover portion 52B of the rotatable slide panel is in its normal position, the cover portion interferes with the upper cover portion 41B of the fixed panel of the first support portion 11, so the slide panel portion 50B cannot be opened in effect. Therefore, the locking portion 7 may be omitted from the second embodiment. In this case, the slide panel portion 50B can be slid simply by rotating the upper cover portion 52B of the rotatable slide panel upward. [Explanation of symbols]
