By forming the wide portion b for preventing the swinging of the rotated door body 2, the door body 2 is opened at the open and rotated position.
The held portion 6 provided integrally with the door body also rotates integrally with the door body 2, and both ends of the held portion 6 are pressed against the wide portion b in a tension bar shape so that the door body 2 is opened and rotated. 2 can be held without causing any runout, and such holding is made up of the wide portion b provided on the upper and lower rails 1 and 8 and the held portion 6 formed on the vertical traveling tools 3a and 3b. Therefore, the steady rest of the door body 2 can be surely performed.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

Two upper rails with an inverted U-shaped cross section with an open bottom 1,1
And a cross section of approximately U, which is laid below and opened at the top
The two door bodies 2,2 can be freely traveled along the two lower rails 8,8 through the vertical running tools 3a, 3b on the door tip side and the vertical running tools 9a, 9b on the rear side. Configured. Specifically, the door body 2
A disc-shaped upper traveling tool 3a is integrally attached to the door body 2 via the mounting shaft 10 at the upper end of the door tip side of the upper rail 1, and the disc-shaped upper traveling tool 3a is mounted on the upper rail 1. Mounted on surface 11. A sub-runner 15 is rotatably attached to the rear upper end of the door body 2 via a runner shaft 14, and the sub-runner 15 is mounted on the mounting surface 11 of the upper rail 1 so that the door body 1 is mounted on the upper rail 1. It is suspended so that it can run freely.

In the lower part of the door body 2, a floor contacting member 16 is provided so as to be vertically movable over substantially the entire length of the door body 2. A lower shaft 13 provided with a slider 12 as a lower traveling tool 3b is provided at the lower end of the door body 2 of the door body 2 downwardly by a spring 23 to urge the slider 12 to a lower rail 8. It is slidably inserted. A slider 17 is provided on the lower rear end of the floor-contacting member 16, and the slider 17 is slidably fitted on the lower rail 8. The raising operation of the floor-contacting member 16 is performed by the operation knob 19, and the raised position is releasably locked so that the floor-contacting member 16 is in an oblique posture so that the slider 17 side thereof greatly floats from the lower rail 8. It can be held in the lifted state (see FIG. 1).

The door body 2 has a vertical rail 1,
It is designed so that it can rotate approximately open with respect to 1,8,8. The opening and rotating structure of the door body 2 will be described in detail below.

A narrow portion a and a wide portion b as shown in FIG. 5 are provided on the upper and lower rails 1 and 8 at the traveling end position of the door main body 2, that is, at the open rotational position where the door main body 2 is opened and rotated, and the spring plate 20 and the like. The channel member 22 formed in (4) is inserted. On the upper surface of the disk-shaped upper running tool 3a fixed to the door body 2, there is formed a rod-shaped held portion 6 which can pass through the narrow portion a and enter the wide portion b. The slider 12 into which the lower rail 8 is inserted is also formed in a substantially rod shape, and the held portion 6 is formed by the slider 12 itself, and both ends of the upper and lower held portions 6 are respectively upper and lower rails. The door body 2 that is opened and rotated by pressing against the wide portions b of 1 and 8 in the form of a tension rod is vertically supported.

In this way, the held part 6 is formed on the vertical traveling tools 3a, 3b,
When the door body 2 is opened and rotated, the narrow rails a and 8 to be passed through the held portions 6 of the vertical running tools 3a and 3b and the both ends of the held portions 6 are pressed against each other to open and close the upper and lower rails 1 and 8 to open. By forming the wide portion b that prevents the swinging of the rotated door body 2, the held portion 6 provided integrally with the door body 2 is also integrated with the door body 2 at the open and rotated position of the door body 2. When the door 6 is rotated integrally, both ends of the held portion 6 are pressed against the wide portion b in a tension bar shape, and the door body 2 is held in the open and rotated position of the door body 2 without causing a shake. The steady rest is surely performed.

When the door body 2 is opened and rotated, the slider 17 and the floor-contacting member 16 near the slider 17 are raised. Further, the upper rail 1 is provided with a notch 21 so that the rear traveling tool 9a can be escaped.

A plurality of wide portions b are formed in the rail length direction so that the door main bodies 2 can be opened and rotated at each wide portion b. FIG. 8 shows another embodiment in which the spring plates 20 are provided so as to face each other, and the narrow portion a
And a wide portion b is formed.

[Effects of the Invention] In summary, the present invention has the vertically traveling tool integrally formed with the held portion, and vertically moves on the upper and lower rail portions at the open pivot position where the door body traveling along the vertical rail opens and pivots. The narrow portion that allows the held portion of the tool to pass through and the wide portion that prevents the swinging of the door body that is opened and rotated by pressing both ends of the held portion are provided, and the held portion is narrower than the narrow portion. Since the width of the door is set and the length of the held portion is set so as to approximately match the wide portion, it is provided integrally with the door body when the door body is opened and rotated. The held part also rotates integrally with the door body, and both ends of the held part are pressed against the wide part in the form of tension rods to hold the door body in the open and rotated position of the door body without causing shake. Such holding can be done by the wide part provided on the upper and lower rails and the vertical traveling tool. Since it is performed with the formed held portion, there is an advantage that the steady rest of the door body can be reliably performed.
