Description of the Related Art Conventionally, in a single-deck general railway vehicle, there is known a device for automatically rotating a plurality of seats for one vehicle so that a crew member can change the seating direction at the starting station. This conventional device has a motor installed in each seat,
The vehicle is provided with a control panel and an operation panel, and the control panel controls the motor of each seat based on a rotation command from the operation panel.

[0003]

However, when the conventional device is applied to a double-deck vehicle and the control panel and the operation panel for the seats on the second floor are arranged on the second floor, the crew members turn to rotate the seats on the second floor. There is the trouble of climbing to the second floor and operating the control panel.

In order to avoid this, it is possible to install a control panel and an operation panel common to all seats on the first and second floors on the first floor. However, in this case, there is a problem that the control panel becomes complicated and large, and it is difficult to install the control panel. In particular, in railway vehicles, the division of labor between the vehicle body and the seats is progressing, and seat manufacturers are installing the control panel for seats in the seats instead of in the vehicle body. Often integrated into one seat.) Required to be delivered. Therefore, if the control panel becomes large, it cannot be installed in one seat, and it is necessary to install the control boards separately in a plurality of seats. Moreover, in that case, cables must be connected between the separate control panels. Also, since the control panel on the first floor also controls each seat on the second floor, it is necessary to connect the control panel and each seat on the second floor with a large number of cables, which hinders the wiring between the first and second floors. There is also the problem of coming.

Therefore, an object of the present invention is, in a double-deck vehicle, not only can all the seats on the first and second floors be easily rotated, but also the control panel can be made compact so that it can be installed in one seat, and the wiring can be reduced. It is to provide a new seat rotation device that can simplify the above.

[0006]

In order to solve the above-mentioned problems, according to the present invention, in a device for rotating a plurality of seats respectively arranged on the first and second floors of a double-deck vehicle, each of the first and second floors is rotated. Connected to the first-floor control panel and the first-floor control panel for controlling the motor of each seat on the first floor, the second-floor control panel for controlling the motor of each seat on the first floor And a transmission cable for transmitting a rotation command from the first floor control panel to the second floor control panel.

Here, the first floor control panel is installed in any one of the first floor seats, and the second floor control panel is installed in any one of the second floor seats. It can be configured.

[0008]

In the seat rotating apparatus of the present invention, a rotation command is output from the operation panel to the first floor control panel, the first floor control panel controls the motors of the first floor seats, and the motors control the first floor seats. Is automatically rotated. In addition, the rotation command is transmitted from the first floor control panel to the second floor control panel via a transmission cable, the second floor control panel controls the motors of the seats on the second floor, and the motors automatically rotate the seats on the second floor. .

As described above, the first-floor control panel only needs to control the motor of each seat on the first floor, and the second-floor control panel only needs to control the motor of each seat on the second floor. Compared with the case of controlling the motors of the seats on the first and second floors, the number of parts of each control panel can be reduced and the parts can be made small, and each control panel can be configured in a small size. Further, since the transmission cable transmits the rotation command, the number of cables can be small.

Then, the control panels 9 and 10 on the first and second floors are powered on, and the power source display lamp 23 of the operation panel 20 is turned on. Thereby, the crew member can confirm that the seat rotation device is in an operable state.

In this state, when a crew member operates the up push button 21 or the down push button 22 of the operation panel 20, a rotation command for up rotation or down rotation is input to the first floor control panel 9, and the operated push buttons 21, 22 are also inputted. The rotation direction indicator lamp inside is turned on. Then, based on a command from the sequencer 31 of the first floor control panel 9, the seats 2 of the A group on the right and left rows of the first floor
After being rotated, the seats 2 of the B group on the right and left rows of the first floor are rotated, and the seating directions of the seats on the first floor are changed.

For a predetermined time after operating the push buttons 21 and 22,
For example, when 60 seconds have passed, next, a rotation command having the same content as that of the first floor is transmitted from the first floor control panel 9 to the second floor control panel 10 via the transmission cable 29. Then, based on a command from the sequencer 31 of the second floor control panel 10, A on the right and left columns of the second floor
After the seats 2 of the group are rotated, the seats 2 of the B group on the right and left rows of the second floor are rotated to change the seating direction of each seat on the second floor. Thus, when all the seats 2 on the first and second floors are rotated, the rotation direction display lamp of the operation panel 20 is turned off after a predetermined time, for example, 120 seconds has elapsed since the pushbuttons 21 and 22 were operated, and the seat rotation work is performed. finish.

Therefore, the crew member has one operation panel 20 on the first floor.
The seating directions of all the seats 2 on the first floor and the second floor can be easily changed only by operating. Moreover, the first floor control panel 9
Need only control the motor 4 and the clutch 5 of each seat 2 on the first floor, and the second floor control panel 10 need only control the motor 4 and the clutch 5 of each seat 2 on the second floor. In comparison with the case of controlling each seat on the first floor and the second floor, the number of parts of each control panel 9 and 10 can be reduced, and the sequencer 31 can be made small with a small number of terminals. Therefore, each of the control panels 9 and 10 can be constructed in a small size, and can be easily incorporated in the internal space of the base 3 of one seat 2. Further, since the transmission cable 29 transmits the rotation command, the number of cables is small, and it can be wired in the limited space between the first and second floors without any trouble.
