<First embodiment / Wire 5 is driven vertically / Guard member 4 is moved vertically>
Hereinafter, examples will be described in more detail. FIG. 1 is a schematic diagram showing a schematic configuration of a railway platform safety device SAFE according to the first embodiment, and FIG. 2 is a perspective view showing an essential part thereof.

  The illustrated safety device SAFE illustrates a case where a vehicle travels on both sides of a railroad platform, and has a plurality of device accommodating portions 1 arranged adjacent to an existing structural pillar and a lateral width slightly narrower than the home width. And the upper frame 2 disposed on the upper part of the device accommodating portion 1, the elevating member 3 that descends from the upper frame 2 toward the home holding hole HO, and the two adjacent elevating members 3 ascending and descending A guard member 4, a wire member 5 that holds the elevating member 3 in a suspended state, a drive member 6 that moves the elevating member 3 up and down through the wire member 5, and a control device (not shown) that controls the drive member 6. It is structured around.

  A plurality of device accommodating portions 1 are discretely arranged orthogonal to the paper surface of FIG. 1, and the upper frame 2 is held by the adjacent device accommodating portions 1 and circulates in a rectangular shape on the same plane. (See FIG. 2).

  Moreover, in FIG. 1, while the raising / lowering member 3 and the guard member 4 on the left side are raised, a boarding / alighting space for the arrived vehicle is secured, while the right raising / lowering member 3 and the guard member 4 are held in the lowered state. As a result, movement from the railroad platform to the track direction is prevented. As shown in FIG. 1, the tip of the right elevating member 3 is inserted into the holding hole HO, and the tip of the elevating member 3 is magnetically attached to the holding hole HO by the magnet MG disposed at the insertion tip. . Therefore, the fixed posture of the elevating / lowering member 3 and the guard member 4 is maintained even in the case of being hit by a strong wind.

  As shown in FIG. 3B, the elevating member 3 includes a base pipe 10 that extends downward in a fixed state to the upper frame 2, and a movable pipe that is guided by the base pipe 10 and can move in the vertical direction. 11, a tip pipe 12 that extends downward continuously from the moving pipe 11, and a magnet MG that is fixed to the tip of the moving pipe 11.

  The moving pipe 11 is a double pipe composed of an inner pipe IN and an outer pipe OUT, and the proximal pipe 10 is configured to slide on the inner peripheral surface of the inner pipe IN. Further, the inner peripheral surface of the tip pipe 12 slides on the outer peripheral surface of the inner pipe IN of the moving pipe 11, and the outer peripheral surface of the tip pipe 12 slides on the inner peripheral surface of the outer pipe OUT of the moving pipe 11. It is configured.

  The guard member 4 includes an upper plate 15 fixed to the moving pipe 11 and a lower plate 16 fixed to the tip pipe 12. 1B shows the moving pipe 11 and the tip pipe 12, the upper plate 15 and the lower plate 16 are shown as transparent for the sake of convenience. In practice, however, the plates 15, 16 are shown. Is made of a punching metal material or the like.

  As shown in FIG. 3B, the horizontal end of the upper plate 15 is fixed by the mounting arms A1 and A1 at the upper and lower positions of the moving pipe 11, and the horizontal end of the lower plate 16 is fixed to the tip pipe. It is fixed by mounting arms A2 and A2 at 12 vertical positions. The other end portions of the upper plate 15 and the lower plate 16 are fixed to the moving pipe 11 and the tip pipe 12 of the adjacent elevating member 3 with exactly the same mounting structure (see FIG. 3A).

  Here, one mounting arm A <b> 2 passes through the tip pipe 12 and is fixed to the end of the wire member 5 inside the tip pipe 12. Therefore, the tip pipe 12 and the lower plate 16 are suspended and held by the wire member 5 and can be raised in response to the five-winding operation of the wire member. Further, the moving pipe 11 and the upper plate 15 rise in response to the rise of the tip pipe 12 and the lower plate 16.

  In order to realize such an operation, the moving pipe 11 is formed with a notch groove GV1 continuous from its lower end surface with an axial length H1, and the mounting arm A2 slides in this notch groove GV1. It is configured as follows. Therefore, the upward movement of the lower plate 16 is prohibited at the uppermost position of the notch groove GV1. Note that FIG. 3C shows a storage state in which the lower plate 16 is raised to the limit position.

  Further, a cut groove GV2 (or a thin groove GV2) having an axial length H2 (≈H1) is formed in the tip pipe 12 from an appropriate upper position toward the tip side. Then, the pin member P1 is inserted from the outer periphery of the moving pipe 11 after the assembling of the elevating member 3 is completed at the position of the cut groove GV2, and the tip thereof is disposed in the cut groove GV2.

  Therefore, when the tip pipe 12 moves upward, the mounting arm A2 of the tip pipe 12 slides in the notch groove GV1 of the moving pipe 11, and the tip of the pin member P1 passes through the notch groove GV2 of the tip pipe 12. Will slide. On the other hand, when the tip pipe 12 is moved downward, no further descent is prohibited at the position where the cut groove GV2 is interrupted, so that the tip pipe 12 does not fall out of the moving pipe 11.

  Similarly, the proximal pipe 10 is also formed with a thin groove GV3 (or a cut groove GV3) having an appropriate length from an appropriate upper position toward the distal end. Then, after the assembly of the elevating / lowering member 3 is completed, the pin member P2 is inserted from the outer periphery of the moving pipe 11 at the position of the thin groove GV3, and the tip thereof is disposed in the thin groove GV3.

  Therefore, when the moving pipe 11 moves downward, the pin member P2 slides on the thin groove GV3 of the proximal pipe 10, and further lowering is prohibited at the position where the thin groove GV3 is interrupted. . Therefore, there is no possibility that the moving pipe 11 falls off from the proximal end pipe 10.

  As shown in FIG. 2, the drive member 6 includes a drive roller RV that is rotated in the forward direction or the reverse direction by the drive motor MO, a driven roller RO that guides the wire member 5, and a weight fixed to the base end of the wire member 5. W. Note that at least three driven rollers RO are arranged at the bending position of the wire member 5, but only one is shown in FIG. The weight W has a weight corresponding to the total weight of the elevating member 3.

  The two drive motors MO, MO arranged at the adjacent positions rotate in the forward direction or the reverse direction in synchronization with each other, thereby driving the respective wire members 5, 5 in the winding direction or the lowering direction. As shown in FIG. 2, the two wire members 5, 5 suspend and hold the left and right positions of the lower plate 16, so that the tip pipe 12 and the lower plate 16 are driven by winding up the wire members 5, 5. Will rise. On the other hand, when the wire members 5 and 5 are driven to be lowered, the tip pipe 12 and the lower plate 16 are lowered based on their own loads.

[Operation when train arrives]
Based on the above, the operation when the train arrives will be described. At the normal time, the elevating member 3 is stable in the lowered state of FIG. In this descending state, at a suitable timing preceding the arrival of the train, the pair of drive motors MO and MO start forward rotation in synchronization with each other, and drive the wire members 5 and 5 in the winding direction.

  Then, the tip pipe 12 and the lower plate 16 are pulled up by the wire member 5 and rise corresponding to the winding drive. At this time, the mounting arm A2 of the tip pipe 12 slides and rises in the cutout groove GV1 of the moving pipe 11, and the tip of the pin member P1 slides in the cutout groove GV2 of the tip pipe 12.

  Then, when the cutout groove GV1 or the cutout groove GV2 is interrupted, thereafter, the tip pipe 12 and the lower plate 16 are integrated with the moving pipe 11 and the upper plate 15, and the lower plate 16 and the upper plate 15 Rises in the polymerized state. At this time, the distal end of the pin member P2 slides in the thin groove GV3 of the proximal end pipe 10. And if the raising / lowering member 3 raises to an appropriate position, the winding drive of drive motor MO and MO will be stopped, and it will be in the raising accommodation state shown in FIG.3 (c).

  As a result, the boarding / exiting space for the arriving train is opened, and passengers can freely move to and from the train.

  In the present embodiment, in accordance with the arrival position of the train, the elevating member 3 at the optimum position is raised and the boarding / exiting space is opened, and the movement preventing state in the track direction by the guard member 4 is maintained in other places. Therefore, the safety of train users is ensured. Moreover, even if the position of the passenger door changes depending on the type of train, this can be appropriately handled.

[Operation when train leaves]
Next, the operation when the train departs will be described. The pair of drive motors MO, MO start reverse rotation in synchronization with each other and drive the wire members 5, 5 in the lowering direction at an appropriate timing when the passengers move.

  Then, the tip pipe 12 and the lower plate 16 start to descend together with the moving pipe 11 and the upper plate 15 from the ascending accommodation state shown in FIG. At this time, the distal end of the pin member P2 disposed on the moving pipe 11 slides in the thin groove GV3 of the base end pipe 10, but further lowering is restricted at a position where the thin groove GV3 is interrupted.

  Therefore, after that, only the tip pipe 12 and the lower plate 16 descend based on their own weight. At this time, the tip of the pin member P1 disposed on the moving pipe 11 slides in the cut groove GV2 of the tip pipe 12, and the mounting arm A2 of the tip pipe 12 slides in the cut groove GV1 of the moving pipe 11. As a result, only the lower plate 16 is lowered.

  As a result of such an operation, the upper plate 15 and the lower plate 16 spread in the vertical direction, and finally, the magnet MG disposed in the tip pipe 12 is seated in the holding hole HO and is stabilized. FIG. 3B shows this fixed state, in which the proximal end pipe 10, the moving pipe 11, and the distal end pipe 12 are extended to the limit state, and the upper plate 15 and the lower plate 16 are expanded in the vertical direction. Stable in condition.

It is structured in the center. In FIG. 4, the illustration of the upper frame 2 disposed between the guide pipe 20 and the device accommodating portion 1 is omitted for convenience.

  In the second embodiment, the guide pipe 20 is disposed in a fixed state, and a mounting arm A3 to which the wire member 5 is fixed is disposed. In addition, a guide groove GV4 is formed in the guide pipe 20 in the axial direction, and the protruding piece PR of the mounting arm A3 passes through the guide pipe 20 and is exposed.

  The elevating member 3 includes an upper ring 21 and a lower ring 22, and the outer peripheral surfaces of the upper ring 21 and the lower ring 22 are fixed to the back surface of the guard member 4 together with the protruding piece PR of the mounting arm A3. The elevating member 3 is integrated, and the elevating member 3 and the mounting arm A3 are integrated.

  And the movement range of the protrusion piece PR of mounting arm A3 is regulated by forming guide groove GV4 from the upper part of guide pipe 20 to the middle of the lower part. The case where the projecting piece PR is located at the lower limit point is a steady state, and movement from the home to the line direction is prevented.

  On the other hand, when the train arrives, the wire member 5 is wound up by the drive member 6, whereby the elevating member 3 and the guard member 4 are integrally lifted to open the boarding / alighting space of the arrived train. Also in the case of this embodiment, only the elevating member 3 at the optimum position rises corresponding to the arrival position of the train, and the movement prevention state by the guard member 4 is maintained in the other portions. Safety is ensured. There is no problem even if the position of the entrance door changes depending on the type of train.

  In the present embodiment, the drive member 6 includes a rack that moves the guard member 4 up and down, a pinion that meshes with the rack, and a drive motor that rotates the pinion in the forward direction or the reverse direction.

  The guard member 4 includes a base bar 40 that is connected to the rack and is driven up and down, and a blocking plate 41 that is fixed to the base bar 40. The blocking plate 41 is made of, for example, a punching metal material. In the railroad platform, a housing groove HO corresponding to the shape and size of the base bar 40 is formed to lower the base bar 40 downward from the platform surface.

  In addition, a passage groove PAS having an appropriate depth is formed in the railway platform so as to lower the blocking plate 41 in response to the lowering operation of the base bar 40. For safety reasons, if the height of the blocking plate 41 is sufficiently secured, the passage groove PAS that accommodates the blocking plate 41 generally penetrates the railroad platform in the vertical direction.

On the other hand, when the guard member 4 descends, the protective member CV falls toward the guard member 4 and the guard member 4 descends to the limit position. Then, the upper part of the guard member 4 is completely covered to bring the railroad platform into a flush state (see FIG. 8B). Therefore, the presence of the accommodation groove HO does not become an obstacle to the movement of passengers.

  In addition, in order to secure the above-described collapse operation of the protective member CV, a mechanism that interlocks the protective member CV and the guard member 4 may be employed (see, for example, FIG. 9B). Moreover, in the structure of FIG.8 (b), although the protection member CV is made into the integral structure, it is good also as a separated structure. For example, if the protective member CV is configured to be separated into a first member G1 that closes the accommodation groove HO in the train traveling direction, and a second member G2 and a third member G3 that close the accommodation groove HO perpendicular to the train traveling direction. The standing height of the second member G2 and the third member G3 can be made equal to the standing height of the first member G1.

For example, as shown in FIG. 8D, as the guard member 4, a base bar 40 connected to a rack and driven to move up and down, and a plurality of blocking bars 42 protruding downward from the base bar 40 may be provided. In this case, an accommodation hole with an appropriate depth is formed in the railroad platform so that the blocking bar 42 can be lowered in response to the lowering operation of the base bar 40.

  In this case, it is not necessary to form the passage groove PAS that penetrates the railroad platform in the vertical direction as in the configuration of FIG. On the other hand, when the passage groove PAS penetrating the railroad platform in the vertical direction is formed, it is also preferable to use a guard member 4 that can be bent.
