Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a schematic exploded perspective view showing two doors 7,7.
Is installed on the upper and lower rails 1 and 2 freely,
A large number of doors 7 may be used. Two guide grooves 8 are formed in each of the upper and lower rails 1 and 2. Traveling shafts 5 are provided projecting from the upper and lower ends of the door main body 3 on the door end side. Runner rollers 9 are rotatably provided on the upper traveling shaft 5 via traveling blocks, and the runner rollers 9 are mounted on the receiving surface of the upper rail 1 so that they can travel. On the lower surface of the rear end of the door body 3,
A door roller 10 is provided and fitted in the guide groove 8 of the lower rail 2 so as to be freely movable. On the upper rail 1, a traveling receiving piece 11 composed of a horizontal piece and a standing piece is formed over the entire length. A hook 12 having a hanging piece is attached to the upper surface of the rear end portion of the door main body 3, and by engaging the hook 12 with the travel receiving piece 11, it is possible to prevent lateral rattling and to travel. There is.

The vertical frame 13 as an example of the receiving body 4 for deciding the closing position of the door main body 3 which is built in the door main body 3 in such a manner is rotatably and rotatably pivoted via the hinge 14. , Vertical frame 1
The door 3 can be retracted from the running position of the door body 3. Then, the upper and lower rails 1 and 2 are extended to a position where the vertical frame 13 is retracted, that is, a position where the closed position of the door main body 3 is crossed in the closing direction, and the door main body 3 can travel to the extended position X. I am doing it. As shown in FIG. 2, the upper and lower rails 1 and 2 of the extension portion X are provided with a riding guide 15 that rises toward the rear side,
At the extension portion X of the door body 3, the runner rollers 9 ride on the upper riding guides 15, and the lower surface of the door body 3 rides on the lower riding guides 15 to lift the door body 3 substantially in parallel and The door roller 10 is lifted from the guide groove 8 and removed, and the hook 12 is lifted from the travel receiving piece 11 to remove the door main body 3 from the upper and lower traveling shafts 5 and 5 with respect to the upper and lower rails 1 and 2. It can be opened and rotated so as to be substantially orthogonal. A catch 16 as an example of the opening rotation holding means 6 is provided at the top and bottom of the extension portion X, and the door main body 3 has traveled to the depth of the extension portion X.
The upper and lower traveling shafts 5 and 5 are fitted and retained by the catch 16, and the traveling shafts 5 and 5 are retained in this manner to open the door main body 3 so as to be substantially orthogonal to the upper and lower rails 1 and 2. It turns.

In this way, the vertical frame 13 as the receiving body 4 that determines the closed position of the door body 3 is rotated and retracted to extend the door body 3 to the extension portion X.
The door body 3 is lifted up substantially in parallel by the ride guide 15, the hook 12 and the door roller 10 are disengaged from the travel receiving piece 11 and the guide groove 8, and the opening rotation holding means is provided at the back of the extension X. By holding the traveling shafts 5 and 5 above and below the tip of the door body 3 with the catch 16 of 6, the door body 3 can be opened and rotated so as to be substantially orthogonal to the upper and lower rails 1 and 2, and the sliding door Such a door is more convenient to use, and in such a case, the traveling shafts 5 and 5 are effectively used, and the receiving body 4,
Open rotation holding means 6 for holding the extension X and the traveling shaft 5.
This makes the structure relatively simple.

Then, the catches 16, 16 serving as the opening rotation holding means 6
As shown in Fig. 5, the catch on the side of the opening rotation direction
16a is displaced with respect to the adjacent catch 16b by an interval b equal to the interval a which is slightly wider than the interval between the guide grooves 8, 8 of the upper and lower rails 1, 2, so that the adjacent open rotation holding means 6, 6 ... The positions of the catches 16 ... Are shifted in the rail length direction so that the plurality of door bodies 3 can be opened and rotated in parallel.

According to such a configuration, after the vertical frame 13 is retracted,
The door body 3a on the front side in the opening rotation direction is moved to the extension point X, the traveling shafts 5, 5 are inserted into the catches 16a, 16a, and the door body 3b on the back side in the opening rotation direction is extended. When traveling to the position X, the hook 12 of the succeeding door body 3b comes into contact with the hook 12 of the preceding door body 3a, the succeeding door body 3b is positioned, and the traveling axes 5, 5 of the door body 3b are made. Is inserted into the catches 16b, 16b, and the two door bodies 3a, 3b arranged side by side in such a state are collectively opened and rotated in the opening and rotating direction. Also, the two sheets can be returned together. FIG. 6 shows another embodiment.

In the embodiment, the door body 3 is lifted by the riding guide 15 at the extension point X and the hook 12 and the door roller 10 are removed from the traveling receiving piece 11 and the guide groove 8. It is also possible to hold the traveling shafts 5 and 5 by the catch 16 without lifting the door 3 and to open and rotate the door main body 3 so as to be substantially orthogonal to the upper and lower rails 1 and 2 in this state. In this case, the door roller 10 and the hook 12 on the rear side of the door body 3 may be like an elastic latch that is biased in the protruding direction by using a spring. or,
Notches may be provided in the upper and lower rails 1 and 2 corresponding to the door roller 10 and the hook 12 at the open and pivot position of the door body 3.

Further, in the embodiment, the receiving body 4 is the vertical frame 13, but the receiving body 4 does not have to be the entire length of the door body 3 in the vertical direction like the vertical frame 13 and may be short. 1, 2 may be provided, and the receiving body 4 may be variously changed in design such that the receiving body 4 can be folded at the door tip of the door body 3 with a hinge or the like.

Further, in the embodiment, the open rotation holding means 6 holds the traveling shafts 5, 5 by the substantially C-shaped catch 16, but the traveling shafts 5, 5 may be held vertically from the upper and lower ends thereof. It's good.

Further, in the embodiment, the receiving body 4 is rotated and retracted, but the retracting may be performed by sliding.

Further, in the embodiment, each of the upper and lower rails 1 and 2 has two, but it may have more than this. In such a case, it goes without saying that the opening rotation holding means 6 is provided at each extension portion X.

[Effects of the Invention] In summary, according to the present invention, a plurality of door bodies are arranged side by side along the upper and lower rails, which are arranged side by side, so that the door bodies can be opened and closed. It is freely installed, and the upper and lower rails extend beyond the closing position of the door body in the closing direction so that the door body can travel up to the extension point. Opening rotation holding means is provided for holding the traveling shaft projecting in the direction of the door so as to open and rotate the door main body substantially orthogonal to the upper and lower rails, and the position of the adjacent opening rotation holding means in the rail length direction. Since it is configured to open and rotate a plurality of door main bodies in a side-by-side arrangement by shifting them, the receiver that determines the closing position of the door main body is retracted and the door main body is run to the extension position. With the opening rotation holding means provided at the back of the extension part, the top and bottom of the door body can be moved up and down. By holding the row axis, the door main body can be opened and rotated so as to be substantially orthogonal to the upper and lower rails, and the usability of the door such as a sliding door is increased, but the rails of the adjacent opening rotation holding means are also provided. By displacing the position in the length direction and opening and rotating a plurality of door main bodies in parallel,
There is an advantage that the door main bodies held by the opening rotation holding means can be collectively opened and rotated at a time, and the workability when the door main body is opened and rotated and returned can be improved.
