[Problems to be solved by the invention]
By the way, as a sliding door of this type, there has been conventionally provided a wheel or a guide roller at least at the lower end of the sliding door, and the sliding door is operated to open and close the opening while rolling on the floor. However, in this case, when the floor through which the wheels and the like pass is a soft floor such as a carpet, a rail is necessary, so that there is a disadvantage that a step is formed on the floor and hinders access. Further, even if the floor is hard to some extent, it is difficult to avoid scratches and deformations on the floor when the sliding door wheels and the like pass frequently.
[0004]
On the other hand, in order to suspend and support the sliding door, a rail is provided in the vicinity of the upper edge of the opening, while a wheel or the like is provided at the upper end of the sliding door via a bracket, and the wheel or the like is hooked on the rail. Thus, it is also considered that the sliding door is supported in a suspended state on the rail, and the lower end side of the sliding door is basically a free end. However, in this way, the vicinity of the rail is visually recognized from the opening, and it is difficult to avoid that the appearance is impaired due to the fact that the rail structure itself tends to become large by supporting the sliding door only at the upper end side. It becomes. In addition, if this is done, the lower end is fluttered and the opening and closing of the sliding door is likely to be rattled, so it is necessary to take some measures.
[0005]
Furthermore, when wheels are arranged at the upper and lower ends within the thickness of the sliding door, the effective opening is reduced by the amount that the wheel is interposed between the sliding door and the opening edge. Is inconvenient.
[0006]
The present invention has been made paying attention to such problems, and can be effectively supported in a state in which the appearance is good and the sliding door is suspended or other cantilevered state. The object of the present invention is to provide a sliding door support device that can be enhanced in function.

Supports non-movable parts placed in The top wall of the movable bracket that is a part of the movable part of the linear guide mechanism and the outer standing wall are brought out to the arrangement position of the sliding door so as not to interfere with the decorative surface, and located on the side of the take-out end. The upper protective frame of the sliding door is attached to the outer standing wall, and the height position of the lower end of the upper protective frame of the sliding door is substantially matched with the height position of the lower end of the support frame, and the frame material is disposed on the sliding door. It is arranged at a position displaced from the position in the plate thickness direction .
[0009]
In this way, when viewed from the sliding door side, the space between the fixed guide portion and the movable portion is concealed behind the decorative surface and is no longer visible, so the linear guide mechanism configured between the fixed guide portion and the movable portion is Even if it becomes large-scale, it can be effectively prevented that it is exposed to the outside and the appearance is impaired. For this reason, it becomes possible to realize a sliding door support device having a good appearance and a stable support state. In addition, the fixed guide portion is provided at a position displaced in the plate thickness direction from the position where the sliding door is disposed, and is not interposed between the sliding door and the opening edge, so that the opening is not substantially narrowed. This structure is effective when it is desired to make maximum use of the opening. In addition, the fixed guide part is accommodated inside the frame material having a hollow body shape, a part of the outer wall of the frame material is used as the decorative surface, and a part of the frame material is adjacent to the sliding door. Since it is configured to function as a support frame that supports the non-movable part arranged at the position, there is continuity in appearance between the sliding door and the non-movable part arranged at the adjacent position of the sliding door. be able to.
[0010]
As a specific embodiment, the fixed guide portion is accommodated in a hollow frame material and a part of the outer wall of the frame material is used as the decorative surface. . For example, at least a part of the frame material is channel-shaped, and a bottom wall that is substantially orthogonal to the sliding door and a standing wall that is substantially parallel to the sliding door function as the decorative surface.

The opening S is opened by moving it to a position where it is substantially superposed.
[0019]
For this purpose, as shown in FIGS. 2, 3, and 4, the support device includes a fixed guide portion 1 that is displaced in the plate thickness direction from the arrangement position of the sliding door D and is arranged at the opening edge S <b> 1, and the sliding door D. And a decorative surface K provided at a position for concealing the fixed guide portion 1 with respect to the arrangement position. A linear guide mechanism is configured by supporting the movable portion 2 movably along the opening / closing direction of the sliding door D on the fixed guide portion 1, and a part of the movable portion 2 does not interfere with the decorative surface K. Thus, the sliding door D is taken out to the position where the sliding door D is disposed, and the sliding door D is attached to the take-out end side.
[0020]
Specifically, as shown in FIGS. 4 and 5, the supporting device for the sliding door D uses an inverted L-shaped fixing bracket 11 composed of a horizontal wall 11a and a hanging wall 11b as a scaffold. The horizontal wall 11a of the bracket 11 has a planar shape that extends above positions that substantially correspond to the non-movable portion L, the movable region of the sliding door D, and the entire region of the opening S, and the hanging wall 11b is the other end of the horizontal wall 11a. It is provided to project integrally downward. And the fixed guide part 1 consists of the said hanging wall 11b and the fixed rail 12 attached to this hanging wall 11b.
