As described above, since the spring 9 can obtain the force for urging the frame 6 leftward in FIG. 1 and the air pressure can obtain the force for pushing the frame 6 rightward in FIG. As a result, there is no possibility that a trouble caused by water will occur. When a motor is used as a driving device, it is necessary to electrically control the amount of advance and retreat of the frame 6, and a circuit for that purpose is required, which complicates the device configuration. Is not required, a circuit for controlling the amount of movement of the frame 6 is not required, and the configuration of the apparatus can be simplified. As a result, the durability of the getting-on / off assist device can be enhanced, and a proper operation can always be performed even on a platform exposed to rain.

In this embodiment, the roller 7 provided on the frame 6 as the support means and the rail 8 on which the roller 7 rides have been described as an example, but the present invention is not limited to this. That is, other forms, for example,
A configuration in which a rail is provided on the frame 6 side and a roller is provided on the base 3b side is also possible. Further, instead of the roller 7 riding on the rail 8, another form such as a cam follower or a pin can be used.

Next, the operation of the getting-on / off assist device according to an embodiment of the present invention configured as described above will be described with reference to FIGS. Here, a case where three getting-on / off assist devices 1 are provided in series will be described as an example.

The first plate 4 covers all the other components including the base 3b during standby and during use.
The first plate 4 is substantially horizontal both during standby and during use, and forms the same plane as the surface of the platform. For this reason, the getting-on / off assistance device 1 does not obstruct the passage of passengers. In the standby state, no compressed air is supplied to the air cylinder 10 and the air cylinder 1
0 does not work. For this reason, the spring 9 is
The frame 6 and the second plate 5 are stored on the lower surface of the first plate 4 by the force constantly applied to the first plate 4.
Therefore, the second plate 5 does not protrude from the edge of the platform during standby, and therefore does not hinder the passage of the train.

FIGS. 6 and 7 are perspective views showing the use state of the getting-on / off assist device according to the present embodiment. When the operator presses one switch (not shown), compressed air is supplied to the air cylinder 10 from an air compressor (not shown). As a result, the air cylinder 10 applies a force to the frame 6 against the force of the spring 9, so that the second plate 5 advances from the edge of the platform 2. Since the air compressor generates a strong force, the time required for transition from the standby state to the use state is about one second. As described above, since the second plate 5 advances to the entrance 21 of the train 20,
The gap existing between the train entrance and platform and the platform is closed. Since the getting on / off assist device according to the present embodiment can shift from the standby state to the use state in one operation, the operator need only press the switch once. FIG. 7 shows a state in which the getting-on / off assistance device 1 has just been used by an operation of a conductor, a station attendant, or the like. As shown in FIG. 7, the getting-on / off assistance device 1 according to the present invention may be provided at a position corresponding to, for example, the getting-on / off opening 21 closest to the conductor compartment. The platform 2 may be provided so as to correspond to all entrances and exits of the train 20.

FIG. 8 is a view showing a switch for operating the getting on / off assist device according to one embodiment of the present invention.
The switch 80 can transmit a signal to the getting-on / off assistance device 1 by wire, wirelessly, or by infrared rays. In the present embodiment, a switch that performs wireless transmission is not necessary because the wireless switch does not require construction work such as wiring installation on the platform 2 and a wired switch may cause mischief on the platform 2. 80 is exemplified. The switch 80 includes a monitor LED 81, an A button 82, and a B button 83. The A button 82 is a button for generating a signal for shifting the getting-on / off assist device 1 from the standby state to the use state. The B button 83 is a button for generating a signal for shifting the getting-on / off assist device 1 from the use state to the standby state. The operator can operate the getting-on / off assistance device 1 by pressing one of these buttons. Therefore, unlike the conventional method, many operations are not required.

In the above description, the second plate 5
Although the example in which the spring 9, the air cylinder 10, and the air cylinder 10 are provided on the base 3b has been described, the present invention is not limited to this. For example, it is also possible to adopt a mode in which the second plate 5, the spring 9, and the air cylinder 10 are provided on the back surface of the first plate 4.

As described above, since the urging means constantly urges the second plate-shaped body in the direction from the vehicle entrance to the platform, when the standby state is changed to the use state, the urging means is turned on. If a force greater than that of the urging means is applied in the direction from the platform to the vehicle entrance, the second plate-like body advances from the edge of the platform, and can close the gap between the platform and the vehicle entrance. As a result, safety when a passenger gets on and off the vehicle can be improved. On the other hand, when the getting on / off of the passenger is completed and the getting on / off assist device is in the standby state, the operation of the pushing means is stopped, and if the pushing means cuts off the force applied to the second plate, the second plate Since a force is constantly applied to the body from the urging means in the direction from the vehicle entrance to the platform, the second plate-like body retreats to a position covered by the first plate-like body. As a result, it is not necessary to provide a drive system such as a cylinder and a motor for shifting from the use state to the standby state, and it is possible to reduce the manufacturing cost. In addition, the manufacturing cost of the getting-on / off assistance device 1 according to the present invention is approximately one third of the device using the motor and the electric circuit.

And urging means for urging the second plate in the direction from the vehicle entrance to the platform, and pushing means for pushing the second plate in the direction from the platform to the vehicle entrance when in use. Take the configuration to prepare.

As described above, since the urging means constantly urges the second plate-shaped body in the direction from the vehicle entrance to the platform, when the standby state is changed to the use state, the pushing means is moved to the platform. If a force greater than that of the urging means is applied in the direction from the vehicle to the vehicle entrance, the second plate-shaped body can advance from the edge of the platform and close the gap between the platform and the vehicle entrance. As a result, safety when a passenger gets on and off the vehicle can be improved. On the other hand, when the getting on / off of the passenger is completed and the getting on / off assist device is in the standby state, the operation of the pushing means is stopped, and if the pushing means cuts off the force applied to the second plate, the second plate Since a force is constantly applied to the body from the urging means in a direction from the vehicle entrance to the platform, the second plate-like body retreats to a position covered by the first plate-like body. As a result, it is not necessary to provide a drive system such as a cylinder and a motor in order to shift from the use state to the standby state, and it is possible to reduce the manufacturing cost.
