It is sandwiched between the frames 35 and is firmly attached.
[0016]
As shown in FIGS. 6 and 7, the sliding door device 1 of the present invention directs the sliding door 2 toward the closed position 7 by biasing the support shaft 3 toward the end point 14 toward the skewed portion 11 of the guide portion 5. An opening prevention means 12 for biasing is provided, and the opening prevention means 12 includes an arm-shaped base 15 and a biasing means 16.
[0017]
The base body 15 includes a substrate 36 and a rib 37 rising from the substrate 36, and the substrate 36 is sandwiched between the straight portion 10 and a skew portion 11 that is inclined with respect to the straight portion 10 in plan view. That is, the base 15 is pivotally supported by the first fixed shaft 20 provided on the guide plate 24 inside the curved shape formed by the straight portion 10 and the skew portion 11 in plan view, so that the base 15 is connected to both ends of the skew portion 11. It is attached so that it can rotate between the starting point 13 and the end point 14 which follow the orthogonal part 10 which becomes. Further, the base body 15 abuts against a blocking piece 39 provided on the guide plate 24 on the starting point 13 side, and rotation beyond the starting point 13 is blocked.
[0018]
The urging means 16 includes a cylinder 41 having a compression spring 40 and a slidably provided in the cylinder 41 and a rod 42 urged forward by the compression spring 40, that is, in a protruding direction. It consists of a device 19. The rear end of the cylinder 41 is outside the curved shape formed by the straight portion 10 and the skew portion 11 in plan view, and is pivotally supported by the second fixed shaft 21 provided on the guide plate 24. The front end of the rod 42 is It is rotatably fixed to a connecting shaft 43 provided at the tip of the base 15. Thus, as shown in FIG. 7B, the pressing device 19 is pivotally supported by the second fixed shaft 21 on the extension line 44 of the base body 15 whose rear end is located between the start point 13 and the end point 14. Therefore, the rod 42 connected to the connecting shaft 43 is biased toward the end point 14 by the force of the compression spring 40 with respect to the base body 15 closer to the end point 14 than the extension line 44. Conversely, the rod 42 is biased toward the start point 13 toward the base 15 closer to the start point 13 than the extension line 44.
[0019]
The base body 15 is provided with a long hole portion 17 oriented in the longitudinal direction by cutting out the substrate 36, and the long hole portion 17 is formed by cutting out a part of the rib 37 on the side portion of the base body 15. There is an entrance / exit 18 that opens toward the straight portion 10 at the start point 13. Further, the first fixed shaft 20 is formed at a position closer to the end point 14 than the start point 13 of the skew portion 11.
[0020]
However, as shown in FIG. 7A, when the sliding door 2 moves horizontally from the opening position 9 toward the closing position 7, the support shaft 3 attached to the sliding door 2 skews the direct portion 10 of the guide portion 5. After moving toward the starting point 13 of the part 11, the long hole part 17 extends from the entrance / exit 18 of the base 15 waiting at the starting point 13 of the guide part 5 by being urged by the pressing device 19 and contacting the blocking piece 39.

By pressing the inner periphery, the base 15 rotates toward the end point 14 against the urging force of the pressing device 19. Further, since the first fixed shaft 20 is formed at a position closer to the end point 14 than the start point 13 of the skew portion 11, the support shaft 3 is guided by the skew portion 11 in accordance with the rotation. It moves inside the rotation locus 45 of the entrance / exit 18 shown in FIG. As a result, the support shaft 3 moves in the long hole portion 17 into the long hole portion 17 that is closer to the first fixed shaft 20 than the entrance / exit 18, and is sandwiched between the ribs 37 on both sides in the long hole portion 17. It is restrained by the base body 15 at this position.
[0022]
Next, as the support shaft 3 and the base body move toward the end point 14, as shown in FIG. 7B, the extension shaft 44 connects the first fixed shaft 20 and the second fixed shaft 21. Further, beyond this, the rod of the pressing device 19 is urged toward the end point 14 with respect to the base body 15 located on the end point 14 side of the extension line 44. Accordingly, the support shaft 3 constrained by the base body 15 is urged toward the end point 14, whereby the sliding door 2 is urged toward the closing position 7. As described above, after the base body 15 and the support shaft 3 restrained by the base body 15 exceed the extension line 44, the sliding door 2 reliably reaches the closed position 7 due to the inertia of the movement of the sliding door 2 and the urging force of the pressing device 19. Therefore, the operation for closing the sliding door 2 to the final closing position 7 is not required, and the operability is good.
[0023]
Further, as shown in FIG. 7C, the support shaft 3 positioned at the end point 14 of the guide portion 5 is restrained by the base body 15 urged in the direction reaching the end point 14 by the pressing device 19, and the support shaft 3 is supported. The shaft 3 is biased toward the end point, so that the sliding door 2 is biased toward the closing position 7, so that the sliding door 2 that has moved to the closing position 7 is subject to reaction at the moving end. It does not open from the closed position 7. As a result, no sound leaks from the gap, impairing the sound insulation, and no light leaks. Furthermore, the air conditioning effect is enhanced and the appearance is excellent. Further, since the opening preventing means 12 automatically prevents the generation of a gap in the sliding door 2 due to the reaction at the moving end, an operation for reliably stopping the sliding door 2 at the closing position 7 is unnecessary, and the operability is excellent.
[0024]
Further, when opening the sliding door 2 at the closed position 7, an operation for opening the sliding door 2 along the skewed portion 11 of the guide portion 5 is performed, so that the base body 15 with the support shaft 3 positioned at the end point 14 is moved to the aforementioned position. It rotates toward the starting point 13 against the urging force of the pressing device 19 and reaches the extension line 44 connecting the first fixed shaft 20 and the second fixed shaft 21 as shown in FIG. 7B. Further, beyond this, when reaching the starting point 13 side from the extension line 44, the pressing device 19 biases the base body 15 and the support shaft 3 constrained thereto toward the starting point 13, so that the sliding door 2 is moved. Be forced. As shown in FIG. 7A, the base body 15 rotated to the starting point 13 is stopped by abutting against the blocking piece 39, and the support shaft 3 restrained by the long hole portion 17 is connected to the base 15 from the entrance / exit 18. It slips out and moves to the straight portion 10 of the guide portion 5 to guide the sliding door 2 toward the opening position 9.
[0025]
In the present embodiment, the anti-opening means 12 is provided on one of the two guide portions 5 arranged in a row, but it can also be provided on both guide portions 5, and in this case, the rotation of both bases 15 can be performed. In order to synchronize, it is preferable to link with a link.
[0026]
