The slide door 100 slides as shown by the two-dot chain line in FIG. At the time of this opening and closing movement, the upper guide rail 11 and the lower guide rail 12 are moderately provided between the door body and the body 1 because the respective front end portions are biased toward the body 1 as shown in FIG. A large gap (W direction) is formed. By setting such a gap, the slide door 100 can be opened and closed without interfering with the body 1.
[0019]
FIG. 3 shows a main configuration around the upper guide rail 11 in this embodiment. As illustrated, the upper guide rail 11 includes an upper rail 13 and a lower rail 14 that are configured in two upper and lower stages. In this example, the front end portion of the upper rail 13 is arranged so as to extend in the sliding direction (arrow F direction) than the front end portion of the lower rail 14. Moreover, although the upper rail 13 and the lower rail 14 are biased toward the body 1 as described above, they are formed and arranged so as to maintain a predetermined interval in the sliding direction.
[0020]
The door body is connected to the roller arms 16 and 17 via the arm base 15. The roller arms 16 and 17 are coupled to the arm base 15 so as to be rotatable around the support shafts 23 and 24. In this case, although not shown in FIG. 3, for example, a link for connecting the roller arms 16 and 17 may be provided. In this case, the roller arms 16 and 17 constitute a parallel link mechanism. The
[0021]
The guide rollers 18 and 19 supported by the roller arms 16 and 17 can move between the upper rail 13 and the lower rail 14 while being separated from each other by a predetermined distance L in the sliding direction. In this example, a pair of guide rollers 18 and 19 are attached to the roller arms 16 and 17, respectively. As described above, the door body coupled to the guide rollers 18 and 19 mounted on the upper rail 13 and the lower rail 14 via the roller arms 16 and 17 is slidably guided so as to be parallel to the body 1.
[0022]
In the vicinity of the front end portion of the upper guide rail 11, the upper rail 13 and the lower rail 14 are offset from each other and are biased toward the body 1 so as not to overlap. Further, at the center portion or the rear portion of the upper guide rail 11, the upper rail 13 and the lower rail 14 are arranged so as to overlap each other.
[0023]
The lower guide rail 12 is constituted by a single guide rail in the present embodiment, but the door main body is arranged via the roller arm 21 and the guide roller 22 so as to align with the guide for the slide door 100 by the upper guide rail 11. To support.
[0024]
In the above case, a stopper or a guide for restricting the position of the movable component included in the upper guide rail 11 and the lower guide rail 12 is provided. As shown in FIG. 3, a load roller 25 that rolls on the lower rail 14 is provided in the vicinity of the guide roller 19 of the roller arm 17, thereby restricting the height direction of the slide door 100. As a result, the position of each movable component member is restricted by the stoppers and the like, and a predetermined operation can be performed appropriately and smoothly.
[0025]
In the above configuration, the operation of the sliding door 100 of the present invention will be described.
First, when the door is closed, the guide rollers 18 and 19 are located at the front end of the upper guide rail 11 and the guide roller 22 is located at the front end of the lower guide rail 12 as shown by the solid line in FIG. The door body is closed to the side opening of the body 1 through the guide rails 11 and 12.
[0026]
When the door is closed, as shown in FIG. 4A, the guide rollers 18 and 19 supported by the roller arms 16 and 17 are slid in the sliding direction between the upper rail 13 and the lower rail 14 as described above. Are separated by a distance L. By arranging the guide rollers 18 and 19 and the guide roller 22 in this way on the upper guide rail 11 and the lower guide rail 12, the sliding door 100 is supported at three points as shown in FIG. 1 (see triangle ABC).
[0027]
Next, when the sliding door 100 is opened, when the sliding door 100 is pulled in the direction of the arrow R, the guide rollers 18 and 19 and the guide roller 22 are respectively connected to the upper guide rail 11 and the lower guide rail as shown in FIG. 12 moves backward from the front end. As a result, the door body is slidably guided away from the body 1, and an appropriate gap is formed between the door body and the body 1.
[0028]
Thus, when the sliding door 100 slides backward, the guide rollers 18 and 19 supported by the roller arms 16 and 17 move between the upper rail 13 and the lower rail 14 while being separated by a distance L in the sliding direction. During this time, the roller arms 16 and 17 rotate around the respective support shafts 23 and 24, and the door body is slidably guided so as to be parallel to the body 1. Then, while maintaining this state, it moves until it is fully opened as shown in FIG.
[0029]
Further, since the sliding door 100 is substantially supported at three points by the upper guide rail 11 and the lower guide rail 12 (see FIG. 1, triangle ABC), only the upper and lower guide rails 11 and 12 are included. The stable operation of the door body can be ensured.
When the opened slide door 100 is closed again, the slide door 100 is slid along the upper guide rail 11 and the lower guide rail 12 in the reverse operation.
[0030]
Here, in the above-described embodiment, an example in which the upper guide rail 11 of the slide door 100 has the upper and lower two-stage configuration of the upper rail 13 and the lower rail 14 has been described. However, in the modified example of the present invention, for example, the upper guide rail 11 The upper and lower relations of the lower guide rails 12 may be reversed, that is, the lower guide rails 12 may have a two-stage configuration.
[0031]
Further, both the upper guide rail 11 and the lower guide rail 12 may have a two-stage configuration. In this case, although the sliding door 100 is substantially supported at four points (see FIG. 1, quadrangle ABDC), since it is supported at a plurality of fulcrums, stable operation can be ensured.
[0032]
As mentioned above, although this invention was demonstrated about suitable embodiment, this invention is not limited only to the said embodiment, A change etc. are suitably possible within the scope of the present invention. For example, the example in which the front end portion of the upper rail 13 extends in the sliding direction from the front end portion of the lower rail 14 has been described, but the front end portion of the lower rail 14 extends in the sliding direction from the upper rail 13. It is possible to obtain the same effects as described above.
Further, the sliding door of the present invention can be applied not only to the side door but also to a so-called back door as long as space is allowed.
[0033]
【The invention's effect】
As described above, according to the present invention, in this type of sliding door, the door body can be slidably supported by only two upper and lower guide rails, and the center guide rail, which has been indispensable in the past, is eliminated. be able to. Thereby, in addition to the improvement in design, the degree of freedom in design design of the side outer panel portion can be greatly expanded. Further, by eliminating the center guide rail, there are advantages that the number of parts can be reduced and the manufacturing cost can be reduced.
