BACKGROUND OF THE INVENTION The present invention relates to an automatic sliding door in a one-box car or the like.

[0002]

2. Description of the Related Art A boarding opening 2 is formed on a side surface of a body 1 of a one-box car as shown in a perspective view of a main part in FIG. An automatic sliding door unit 4 is provided with a gap S formed on the step portion 3 for use, and a connecting bracket 5 having an inner end connected to the automatic sliding door unit 4 is projected outward through the gap S. As shown in the cross-sectional view of FIG. 5, the inside of the slide door 6 is connected to the outer end of the connection bracket 5, and the gear motor 42 of the automatic sliding door unit 4 is operated, so that the connection bracket 5 is moved within the gap S. The vehicle is moved in the front-rear direction so that the entrance 2 can be automatically opened and closed by the slide door 6. Reference numeral 41 in FIG. An indoor floor, 7 is a weather strip provided at the opening side of the step portion 3.
In such a conventional structure, it is necessary to provide a gap S as a path for the connecting bracket 5, and the sliding door 6
When the sliding door 6 is in the fully opened state, the gap S is hidden from the outside when the sliding door 6 is in the fully closed state.
Is seen from the outside, and the appearance around the step is deteriorated. In addition, there is a possibility that a child or the like may reach into the gap S and be caught by the sliding door 6, which is dangerous. There was a point.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and does not provide an automatic sliding door capable of improving the appearance around a step and enhancing safety. The gist of the present invention is that the automatic sliding door unit is connected to a bracket protruding outward through the clearance from an automatic sliding door unit disposed with a gap formed on the step of the vehicle entrance, and the operation of the automatic sliding door unit is performed. In the automatic sliding door that automatically opens and closes the entrance via the bracket, a curtain that is connected to the bracket and that opens and closes the gap in conjunction with the bracket is vertically provided between the step and the automatic sliding door unit. It is.

[0004]

When the automatic sliding door unit operates, the bracket moves in the front-rear direction. At this time, the curtain opens and closes the gap in conjunction with the bracket. When the sliding door is fully opened, the gap is closed by the curtain. By being hidden from the outside, the appearance around the step is improved, and the danger of a child or the like getting into the gap is avoided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1 is an enlarged cross-sectional view taken along the line AA in FIG. 4, FIG. 2 is a plan view of an automatic sliding door unit,
FIG. 3 is a perspective view showing a main part of the present invention. In the figure, an auto-slide door unit 4 is disposed on a boarding step 3 at the bottom of a boarding opening 2 formed on the side surface of a body 1 of a one-box car. The upper surface is covered by an upper surface plate 41 disposed flush with the floor F in the room, and a drive gear 43 driven by a gear motor 42 is provided below the upper surface plate 41 as shown in FIG. And pulleys 45 and 46 are rotatably arranged.
3. A belt 44 having teeth formed inside is wound around the pulleys 45 and 46, and a belt guide 47 for guiding the belt 44 is provided. The inner end of the connecting bracket 5 is fixed to the belt 44. The connecting bracket 5 is horizontally protruded outward through a gap S between the automatic sliding door unit 4 and the step portion 3 for riding, and an inner surface of the sliding door 6 is provided at an outer end of the connecting bracket 5. Is fixed. A weather strip 7 is attached to the gap S on the side of the riding step 3 so as to protrude upward.

In this embodiment, a guide rail 8 is arranged on the lower surface of the upper plate 41 in the longitudinal direction (front-rear direction) of the vehicle. A guide roller 10 is rotatably fitted therein, and a roller shaft 10 a that rotatably supports the guide roller 10 is provided upright from the connection bracket 5. One end of a bellows-shaped bellows curtain 9 is connected to the roller shaft 10a. The bellows curtain 9 is moved from the side of the auto slide door unit 4 toward the step part 3 for riding so that the gap S can be opened and closed. It is arranged vertically.

In such a structure, the driving gear 43 is rotated by the driving of the gear motor 42, and the belt 44 is rotated.
The sliding door 6 can automatically open and close the entrance 2 with the rotation of the connecting bracket 5 in this example.
The bellows curtain 9 opens and closes in the direction of opening and closing the gap S in conjunction with the opening, so that when the slide door 6 is fully opened, the gap S is closed by the bellows curtain 9 and the inside of the gap S is hidden from the outside. As a result, the surrounding area will exhibit a neat appearance. Further, since the gap S is closed by the bellows curtain 9 in the fully opened state, it is possible to properly prevent an accident such as a child or the like putting his hand in the gap S and being caught.

[0008]

According to the present invention, the automatic sliding door unit is connected to a bracket protruding outward through the clearance from the automatic sliding door unit provided with a gap formed on the step of the vehicle entrance, and operates the automatic sliding door unit. In the automatic sliding door that automatically opens and closes the entrance via the bracket, a curtain that is connected to the bracket and that opens and closes the gap in conjunction with the bracket is vertically provided between the step and the automatic sliding door unit. In the fully opened state of the slide door, the gap is closed and concealed by the curtain, so the appearance around the step at the entrance is clearly improved,
Further, since the gap is closed by the curtain, the danger of a child or the like getting his hand into the gap and being pinched by the sliding door is avoided.
