Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a supporting structure for a sliding door of a one-box type automobile, for example.

[0002]

[Prior art]

 As shown in Fig. 3, a slide door (3) is attached to the side entrance (2) of the one-box type automobile (1). Conventionally, in the sliding door (3), a door bracket (4) is attached to the sliding door (3) as shown in FIG. 4, and a roller bracket (5) is attached to the door bracket (4). It is rotatably attached via (4A), and the horizontal guide rollers (6A, 6B) are pivotally supported by the front and rear support parts (5A, 5B) of the roller bracket (5), and the central support part (5C) is supported. The vertical main roller (6C) was pivotally supported, and a structure was adopted in which the main roller (6C) and the guide rollers (6A, 6B) were supported by rails (7).

[0003]

[Problems to be solved by the device]

 However, in the above conventional configuration, there is a gap d (play) between the guide rollers (6A, 6B) and the inner walls (7A, 7B) of the rails (7), and the roller bracket (5) is separated by the gap d from the shaft ( 4A) as the center rotates (swings) back and forth as shown by the arrow, the main roller (6C) does not become parallel to the rail (7), and the slide door (3) slides smoothly. There was a problem that there was no.

[0004]

[Means for Solving the Problems]

 As a means for solving the above conventional problems, the present invention is a door bracket (14) attached to a sliding door (13) and a roller bracket (15) rotatably attached to the door bracket (14). And a pair of front and rear horizontal guide rollers (16A, 16B) axially supported by the roller bracket (15) and a vertical main roller (16C) axially supported between the pair of horizontal guide rollers (16A, 16B). ) And an elastic stopper (18) that is pushed out from the door bracket (14) and comes into pressure contact with the side edge of the roller bracket (15), and one guide roller (16A) is attached to the inner wall (17A of the rail (17A). ) And the other guide roller (16B) is in contact with the outer wall (17B) of the rail (17) so that the main roller (16C) is horizontal with the rail (17). It provides the structure.

[0005]

[Action]

 According to the present invention, the roller bracket (15) is forcibly shaken by the elastic stopper (18) extended from the door bracket (14), and one of the horizontal guides pivotally supported by the roller bracket (15) is used. The roller (16A) abuts the inner wall (17A) of the rail (17) without a gap, and the other horizontal guide roller (16B) abuts the outer wall (17B) of the rail (17) without a gap. In this state, the main roller (16C) is parallel to the rail (17).

[0006]

【Example】

 The present invention will be described with reference to one embodiment shown in FIGS. 1 and 2. A door bracket (14) is attached to the front edge of the sliding door (13), and the door bracket (14) is attached to the door bracket (14). The roller bracket (15) is rotatably attached via the shaft (14A), and the horizontal guide rollers (16A, 16B) are attached to the front and rear support parts (15A, 15B) of the roller bracket (15). The main support (15C) is supported by a vertical main roller (16C). A stopper (18) is extended from the door bracket (14), and an elastic member made of rubber, plastic, or the like that is in pressure contact with the front edge of the roller bracket (15) is provided at the tip of the stopper (18). The body (18A) is attached.

In the above structure, the roller bracket (15) is forcibly swung in the direction of arrow A in FIG. 2 by the elastic body (18A) of the stopper (18) of the door bracket (14), and as a result, the front horizontal direction. The guide roller (16A) abuts the inner wall (17A) of the rail (17) without any gap, the horizontal guide roller (16B) on the rear side abuts the outer wall (17B) without any gap, and in this state, the main roller (16C) ) Is maintained parallel to the rail (17). Then, the slide door (13) slides back and forth in the closing direction (arrow B) and the opening direction (arrow C).

The present embodiment is not limited to the above embodiment, and the supporting structure of the slide door may be provided not only at the upper edge portion of the slide door but also at the middle portion or the lower edge portion, and the elastic stopper. A spring or the like may be attached instead of the elastic body.

[0009]

[Effect of device]

 Therefore, in the present invention, the play of the guide roller is eliminated and the main roller is maintained parallel to the rail, so that the sliding door can be opened and closed smoothly.
