[Problems to be solved by the invention]
However, providing guide rails on the floor requires a new construction of Sanwa clay, which is troublesome. Also, if there is a guide rail on the floor, it is not barrier-free, and it is inconvenient for cleaning.
[0006]
Therefore, an object of the present invention is to provide an opening / closing device including a sliding door that can easily suppress the lateral swing of the hanging door without a guide rail on the floor.
[0007]
[Means for Solving the Problems]
Hereinafter, the present invention will be described. In addition, in order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are added in parentheses, but the present invention is not limited to the illustrated embodiment.
[0008]
The invention according to claim 1 has two sliding doors (12, 13), and at least one of the sliding doors has a hanging wheel (201a, 201b) provided on an upper part thereof on a guide rail (202a, 202b). An opening / closing device (1B) configured as an upper hanging sliding door that rolls to open and close an opening and has no rail below the opening, and guide rollers (15a, 15b) are provided on a floor surface (FL). The upper hanging sliding door is provided with the guide roller in a lower guide groove (207a, 207b) formed at a lower end of the sliding door, and the upper hanging sliding door is cooperated with the guide groove and the guide roller. Of the two sliding doors, and the side rollers (300a, 300b) attached to each of the two sliding doors are provided on the other side. Providing an opening and closing apparatus characterized by being regulated deflection transverse to each other by being loosely fitted in the id groove (126, 127) to solve the above problems.
[0009]
According to the present invention, at least one shoji is guided by the guide rollers attached to the floor while being guided in the running direction at one point in the indoor and outdoor directions, and has its own plane rigidity in the vertical direction. Together, side contact is suppressed. Since each of the two sliding doors is provided with a side roller that is guided by a side guide groove of the other sliding door, each of the two sliding doors is involved and generates rigidity in a plane direction that cannot be constituted by an individual sliding door alone. And increased resistance to twisting. Therefore, as a whole, at least one point is fixed to the floor surface by the guide roller and the rigidity against twisting of each sash is increased, so that one side is suppressed from warping even when receiving a force in the front-rear direction due to wind, etc. Can be easily suppressed.

[0029]
A side roller 300a is attached to the lower part of the left side surface of the combination frame 133 of the outer sliding door 13. A side roller 300b is attached to the lower part of the right side of the joining frame 124 of the inner sash 12. Hereinafter, the configuration and operation of the side rollers 300a and 300b will be described with reference to FIGS. FIG. 4A is a perspective view schematically showing the layout of the outer sash 13, the side rollers 300 a attached thereto, and the guide rollers 15 (showing the inside of the outer sash 13 as see-through). . FIG. 4B is a diagram schematically illustrating a planar arrangement of the outer sash 13 and the inner sash 12, the guide rollers 15a and 15b, and the side rollers 300a and 300b. FIG. 5 is a schematic perspective view of the side roller 300a of the outer sash 10 inserted into the side guide groove 126 of the inner sash 12 as viewed obliquely downward from the outdoor side.
[0030]
The side roller 300a of the outer shoji 13 is attached to the lower part of the left end surface of the mating frame 133 and is fixed by screws 304a to 304c, and the inner shoji 12 is formed in a substantially "S" shape from the lower end of the mounting part 303a. An arm portion 301a extending to the side is provided, and a roller 302a is rotatably mounted on the upper end of the arm portion 301a in a horizontal direction. The roller 302a is inserted into a side guide groove 126 (see also FIG. 2) provided in the lower part of the inner sash through a slit-shaped horizontal opening 126a of the inner sash 12 via an arm portion 301a, and is inserted into the side guide. It is in contact with the inner surface of the groove 126.
[0031]
On the other hand, the side roller 300b of the inner sash 12 is in contact with the lower part of the right end surface of the mating frame 124 and is fixed by three screws (not shown). An arm portion 301b extending in the shape of the outer sash 13 and a roller 302b rotatably mounted in a horizontal direction on the top surface of the tip of the arm portion 301b. The roller 302b is inserted into the side guide groove 127 (see also FIG. 2) provided in the lower part of the inner sash from the slit-shaped horizontal opening 127a of the outer sash 13 via the arm portion 301b, and the side guide is provided. It is in contact with the inner surface of the groove 127.
[0032]
With reference to FIG. 4 (B), the opening / closing device 1B configured as described above uses the guide rollers 15a and 15b to control the floor surface against swinging in the indoor and outdoor directions at one point of each of the outer sliding door 13 and the inner sliding door 12. Fixed to FL. In addition, the outer sash 13 and the inner sash 12 are mutually restrained by side rollers 300a and 300b, respectively, and the rigidity of the sash against twisting is increased. Therefore, even if a force in the indoor / outdoor direction is received by wind or the like, the one surface side is prevented from warping, and it is easy to suppress the “lateral vibration” in the indoor / outdoor direction. The roller 302a of the side roller 300a of the outer sash 13 is accommodated in the side guide groove 127 of the inner sash 12 to secure a trajectory that keeps a certain distance from the inner sash 12 when opening and closing. Similarly, the roller 302b of the side roller 300b of the inner sash 12 is housed in the side guide groove 126 of the outer sash 13 to secure a trajectory that keeps a certain distance from the outer sash 13 at the time of opening and closing.
[0033]
