<p>PROBLEM TO BE SOLVED: To provide a fall preventive apparatus which removes a long plate of a length greater than the entire length of a train at a breath to make traffic of all passengers free and returns the long plate to the original position after completion of getting off and getting on.SOLUTION: In the tip 1 of a platform, a large number of long plates 2 are connected to a length beyond the entire length of a train, and the large number of the long plates 2 are attached to the main shaft 12 of a swinging arm provided gear 15 of a hoist unit 9 in a swingable way. The tip shaft 16 of the swinging arm is engaged in a support hole 5 on a lower part of the long plate 2, and an upper rack toothed pull rod 18 and a lower rack toothed pull rod 21 are engaged simultaneously in the vertical direction. The upper rack toothed pull rod 18 and the lower rack toothed pull rod 21 are connected to those of the adjacent hoist unit to form a long pull rod 21. The upper long pull rod is pulled in the right direction to raise the long plate 2 by about 1 m from the upper surface of the platform so as to prevent passengers from getting on from the platform and getting off the platform, and the lower long pull rod 21 is pulled in the right direction to lower the long plate 2 relative to the upper surface of the platform so as to allow passengers getting on and getting off.</p> |
