Description

[Detailed Description of the Invention] The present invention relates to a side sliding door device provided at a side entrance of a railway vehicle.

In recent years, from the viewpoint of reducing construction limits, railway vehicles have been constructed with side stances inclined toward the center of the vehicle body, as shown in FIG. When the side structure is sloped in this manner, the side sliding door 2 also follows the same slope. In such a side sliding door 2, since the degree of contact between the side sliding door 2 and the lower rail increases, the lower rail and the rail slider wear quickly, and maintenance is required frequently. Also, side sliding door 2
Since this is a support method using a door hanging wheel, when the side sliding door 2 is pressed against the entrance pillar side by the door engine at the time of closing, the door end side becomes floating, creating a gap and generating noise when the vehicle is running. There was a drawback. In order to prevent this noise, the side sliding door 2
There is a structure in which guide rollers 1 are provided on both sides of the central part of the sliding door, but in the structure where the side sliding door is inclined as described above, the displacement on the lower rail surface is large, causing early wear of the sliding metal and the above-mentioned noise. The drawback was that it was not very effective in prevention.

In view of the above points, the present invention, in a side sliding door device having an inclined side sliding door, eliminates the gap between the side sliding door and the side sliding door support member when the door is closed, and reduces the noise generated from the side sliding door portion when the vehicle is running. The purpose is to prevent

The present invention provides a cylindrical guide roller having a contact surface having an angle corresponding to the inclination angle α of the side sliding door on either one of the side sliding door or the door pocket post, and By providing a sliding plate with an inclination that contacts the guide roller at a position corresponding to the guide roller and presses the side sliding door against the door bag pillar as the side sliding door moves, the deflection of the side sliding door is reduced. The feature is that it can be prevented.

Next, the present invention will be explained with reference to an embodiment shown in the drawings. Figure 2 is a front view of the side sliding door device according to the present invention.
3 is a view taken along the line AA in FIG. 2, FIG. 4 is a view taken along the line BB in FIG. 2, and FIG. 5 is a perspective view showing the sliding plate and guide rollers provided on the side sliding door. In the figures, the same reference numerals as in the conventional example indicate the same members. 3 is made of a material such as nylon, and the inclination angle α of the side sliding door 2 is
It is a cylindrical guide roller forming a contact surface having an angle along , and is provided at a position opposite to the side sliding door 2 at the lower part of the inner door bag pillar 10 forming the entrance/exit 13. The entrance is constituted by an inner door pillar 10 and an entrance pillar 14 provided at a position opposite to the inner door pillar 10. Reference numeral 4 denotes a sliding plate disposed at the lower part of the guide side of the side sliding door 2, which also serves as a cover plate for preventing damage to the lining 16 constituting the side sliding door 2. A sloped portion 11 is provided that protrudes toward the indoor side. 5 is side sliding door 2
6 is an upper rail that supports the side sliding door 2 against the roof.
7 is a door engine that drives the side sliding door 2, and 8 is a door hanging wheel that has rollers 9 and supports the side sliding door 2. 12
is a guide groove 15 formed on the lower end surface of the side sliding door 2.
This is a metal plate provided on the bottom rail 5, and is arranged opposite to the lower surface rail 5.

In such a configuration, the door engine 7 moves the side sliding door 2 toward the entrance pillar 14 and opens the doorway 1.
3, the inclined portion 11 of the sliding plate 4 hits the guide roller 3 and the side sliding door 2 is pushed toward the outside of the vehicle. This prevents the side sliding door 2 from moving toward the indoor side due to its inclination, and by pressing it toward the outside of the vehicle, eliminates the gap between the side sliding door 2 and its support material, thereby reducing noise generation when the vehicle is running. To prevent. Further, even when the side sliding door 2 is pressed against the entrance pillar 4 and the door end side becomes floating, the above-mentioned action can prevent contact noise between the lower surface rail 5 and the sliding metal 12 due to vehicle vibration.

Furthermore, when moving the side sliding door 2 to close the entrance/exit 13 as described above, the contact surface of the guide roller 3 with the sliding plate 4 has an angle corresponding to the inclination angle α of the side sliding door 2. Due to the contact between the guide rollers 3 and the sliding plate, an upward force is applied to the side sliding door 2. Therefore, when pressing the side sliding door 2 in the left-right direction to prevent its vibration, contact between the side sliding door 2 and the lower rail 5 is avoided in order to apply a force that pushes the side sliding door 2 upward. It is possible,
It is possible to prevent problems such as wear caused by contact between the lower surface rail 5 and the side sliding door 1.

According to such a configuration, the inner lining 16 of the side sliding door 2
A sloped portion 11 is provided on the sliding plate 4 which also serves to prevent damage to the
In addition, with a simple structure in which guide rollers 3 facing the sliding plate 4 are provided on the inner door bag post 10, vibration of the side sliding door 2 when the vehicle is running can be prevented, and noise accompanying the vibration can be eliminated.

By the way, in the above configuration, a configuration in which a sliding plate is provided on the side sliding door and a guide roller is provided on the door pocket pillar is explained, but the present invention is not limited to this.
Even if the arrangement is reversed, the same effect can be obtained. Furthermore, although the side sliding door 2 is configured to be pushed toward the outside of the vehicle, it may also be configured to be pressed toward the inside of the vehicle.

As explained above, according to the present invention, it is possible to eliminate the gap when the side sliding door is closed with a simple configuration, and it is possible to prevent the generation of noise due to vibrations when the vehicle is running.
