An automatic slide door 6 connected to a bracket 5 protruding outward through the gap S from an automatic slide door unit 4 arranged with a gap S formed on a step 3 of an entrance, A bellows curtain 9 is provided which is connected to the bracket 5 and closes the gap S when the automatic slide door 6 is fully opened.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to an automatic slide door in a one-box car or the like.

[0002]

[Prior art and its problems]

 An entrance 2 is formed on the side surface of the body 1 of the one-box car as shown in the perspective view of the main part in FIG. 4, and conventionally, a gap S is formed on the step portion 3 for the passenger, which constitutes the bottom of the entrance 2. And the automatic slide door unit 4 is formed, and the connecting bracket 5 whose inner end is connected to the automatic slide door unit 4 is projected outward through the gap S, as shown in the sectional view of FIG. By connecting the inside of the slide door 6 to the outer end of the connecting bracket 5 and operating the gear motor 42 of the automatic slide door unit 4, the connecting bracket 5 is moved in the front-rear direction within the gap S. The entrance 2 is configured so that it can be automatically opened and closed by the slide door 6, and reference numeral 41 in FIG. 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 passage for the connecting bracket 5, and when the slide door 6 is fully closed, the gap S is hidden from the outside, but the slide door 6 is fully opened. In the state, there is a problem that the gap S is visually recognized from the outside, and the appearance around the step is deteriorated. Also, a child or the like can put his / her hand in the gap S and be caught by the slide door 6. There was a problem that it was dangerous and dangerous.

[0003]

[Means for Solving the Problems]

 The present invention has been devised in view of the above conventional problems, and an object thereof is not to provide an automatic sliding door capable of improving the appearance around the step and improving the safety. , Is connected to a bracket projecting outward through the gap from an automatic slide door unit arranged with a gap formed on the step of the entrance, and through the bracket by the operation of the automatic slide door unit. In the automatic slide door that automatically opens and closes the entrance, a curtain that is connected to the bracket and that opens and closes the gap by interlocking with the bracket is vertically provided between the step and the automatic slide door unit. .

[0004]

[Action]

 When the auto slide door unit operates, the bracket moves in the front-rear direction, and at this time, the curtain interlocks with the bracket to open and close the gap, and when the slide door is fully open, the gap is closed by the curtain, so the gap is opened from the outside. It will be hidden and the appearance around the step will be good, and the risk of children putting their hands in the gap will be avoided.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an enlarged cross-sectional view taken along the line AA in FIG. 4, FIG. 2 is a plan view of an automatic slide door unit, and FIG. 3 is a perspective view showing a main part of the present invention. In the figure, an automatic slide door unit 4 is arranged on a step portion 3 for riding at the bottom of an entrance 2 formed on a side surface of a body 1 of a one-box car. An upper surface plate 41, which is arranged flush with the floor F in the room, covers the upper surface thereof. Below the upper surface plate 41, as shown in FIG. 2, a drive gear 43 driven by a gear motor 42. And pulleys 45 and 46 are rotatably arranged. A belt 44 having teeth formed inside is wound around the drive gear 43 and the pulleys 45 and 46, and a belt guide 47 that guides the belt 44 is provided. The belt 44 has an inner end portion of the connecting bracket 5 fixed to the belt 44. The connecting bracket 5 includes the automatic sliding door unit 4 and the step portion 3 for riding. The gap S is protruded horizontally and into the outward to the inner surface of the sliding door 6 on the outer end of the connecting bracket 5 is made to have been fixed. A weather strip 7 is attached to the step S side of the clearance S so as to project upward.

In this example, a guide rail 8 is arranged on the lower surface of the upper surface plate 41 in the longitudinal direction (front-rear direction) of the vehicle, and the guide rail 8 has a channel shape with an open bottom. A guide roller 10 is rotatably fitted therein, and a roller shaft 10a for rotatably supporting the guide roller 10 is erected from the connecting bracket 5. Further, one end of a bellows-shaped bellows curtain 9 is connected to the roller shaft 10a, and the bellows curtain 9 is moved from the side of the automatic slide door unit 4 toward the side of the riding step 3 so that the gap S can be opened and closed. It is arranged vertically.

In such a structure, the drive gear 43 is rotated by the drive of the gear motor 42, and the belt 44 is rotated, whereby the connecting bracket 5 moves back and forth in the gap S as the belt 44 rotates. The sliding door 6 can automatically open and close the entrance 2 by this, and in this example, the direction in which the bellows curtain 9 opens and closes the gap S in conjunction with the connecting bracket 5. Since the sliding door 6 is fully opened and closed, the gap S is closed by the bellows curtain 9 when the sliding door 6 is fully opened, and the inside of the gap S is hidden from the outside, and the periphery has a neat appearance. . Further, since the gap S is closed by the bellows curtain 9 in the fully opened state, it is possible to favorably prevent an accident such as a child getting his or her hand caught in the gap S and being caught.

[0008]

[Effect of device]

 The present invention is connected to a bracket projecting outward through the gap from an auto slide door unit provided with a gap formed on the step of the entrance, and the bracket is operated by the operation of the auto slide door unit. In the automatic slide door that automatically opens and closes the entrance through the curtain, a curtain that is connected to the bracket and that opens and closes the gap in conjunction with the bracket is hung between the step and the auto slide door unit. As a result, when the slide door is fully opened, the gap is closed and hidden by the curtain, so the appearance around the steps of the entrance is improved and the gap is closed with a curtain, so children and others can use it. It is possible to avoid the risk of putting your hand in the gap and being caught in the sliding door.
