DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Next, an embodiment of the present invention will be described.

FIG. 1 is an external view of a sliding door device for a vehicle according to a first embodiment of the present invention, and FIG. 2 is a conceptual diagram of the sliding door device for a vehicle according to the first embodiment of the present invention. In the figure, 1 is a vehicle body, 2a is a front door up to the bonnet side surface 3 in the closed position, 2b is a front door up to the bonnet side surface in the open position, 11 is an upper rail as a guide rail, and 21b is an open state sliding with the upper rail 11. An upper rail, which is a guide rail, 12 is a center rail, which is a guide rail, and 22b is a center rail, which is an open guide rail that slides with the center rail 12.

It is necessary to provide the tire 13 slightly inside so as not to hit the front door 2a which opens and closes, or to warp the guide rail outward. The size of the front door including the bonnet side surface 3 is to allow the front door to slide forward without being pulled forward.

To get on and off, open the front door 2a to the open position. As a result, a sufficient opening is obtained, so that the side surface of the vehicle only needs a space substantially equal to the thickness of a human. The reason for opening the front door 2a before sliding is that
This is because there is no interference with the rear door, and in many cases, the vehicle is parked in the parking position at the back when parking normally. In this case, there is often room to slide the door forward.
Although not shown, a lock mechanism in a closed position and an open position similar to a normal sliding door that opens backward is provided. In addition, it is possible to make the upper rail 11 and the lower rail 12 apart from each other more firmly. Also, unlike ordinary hinged doors, the sliding door has a small projected area in the operating direction, so it is difficult to receive wind pressure, and because it does not move in a direction perpendicular to a large sliding area, it suddenly closes due to the wind. Less danger.

Embodiment 2 FIG. FIG. 3 is a conceptual diagram of a vehicle sliding door device according to Embodiment 2 of the present invention.
In the figure, 14 is a guide rail, 24b is a guide rail 14

In FIG. 13, reference numeral 30 denotes a crushable zone line, and reference numeral 31 denotes a conventional sliding door that opens backward. The area before the crushable zone line 30 is the crushable zone. Even in the situation where the center rail is long and the front fender is not split, the split center rail allows the part without the split center rail of the front fender to be provided as a crushable zone to absorb the impact at the time of collision. Will be possible. And in the case of a frontal collision or a side collision at the intersection where there is a high possibility of all collisions, the crushable zone near the tip of the front fender is likely to collapse and absorb the impact at the time of collision,
The possibility of breakage of the center rail can be reduced. This has the effect of preventing the occupant from being trapped inside the vehicle due to breakage of the center rail. Furthermore, since there is no center rail in the crushable zone, there is an effect that crushable is not affected.

FIGS. 4 and 13 show a sliding door which can be opened in combination with a conventional sliding door 31 which opens backward. In this case, if the front and rear upper rails and lower rail interfere, there is no problem if the mounting height is shifted up and down.

According to the same concept, the guide rail can be divided into three parts. In this case, the bending moment applied to the guide rail and the roller around the vertical axis of the door and the guide rail becomes about three times stronger at the time of full opening than when there is no division.

In the case where the guide rail is divided into two or three parts, the ratio of the door protruding from the front fender becomes large. For example, a fluorescent color (not shown) or a light recursive label (not shown) may be attached to the inside and outside of the door to prevent a collision. The warning is displayed to increase safety.

If it is not convenient to provide the roller extension rod 26 shown in FIG. 5, the divided guide rails 15hc and 15ho shown in FIGS.
Corresponding rollers may be provided before and after the upper part of the window frame.

The above mechanism is naturally mirror-symmetric on the left and right sides of the vehicle. Note that the above components can be variously combined, and the respective effects can be obtained by selecting the components according to the purpose. Further, although the description has been made for a vehicle, if the invention is applied to a transportation system, for example, a ship or an aircraft, the effect of preventing the door from being flung by a gust than the door space at the time of getting on and off can be expected similarly to the vehicle.
