The guide roller 24a regulates the lateral movement of the door body 1.

Next, the opening / closing operation of the door body 1 will be described with reference to FIG.

When the right end portion of the door main body 1 is pressed in the direction of arrow F, the door main body 1 rotates counterclockwise about the upper rotary shaft 16 and the lower rotary shaft 24, so that the shaft 27a passes through the door main body 1. The guide arm 28 rotates clockwise around the shaft 26a to move to the front side.

Thus, the upper rotary shaft 16 and the lower rotary shaft 24 move to the left by being guided by the upper rails 9a and 9b and the guide rail 25, respectively, and the guide arm 28 is finally positioned at 28 ', and the shaft 27a is Located at 27a ', the door body 1 is at a position 1'perpendicular to the upper rails 9a, 9b and the guide rail 25. That is, it is fully opened.

When a force in the direction opposite to the arrow F, that is, a force in the arrow F'direction is applied to the door main body 1, the door main body 1 operates in the opposite manner.

In this case, when the door body 1 is opened, as shown in FIG. 6, the portion of the door body 1 on the right side of the vertical rotation shaft 23 is located on the side facing the vertical frame 6, and the right end of the door body 1 is The dead space surrounded by the locus 32 and the locus 33 on the front side surface of the door body 1 required for opening and closing the door body 1 is extremely small.

Further, as shown in FIG. 7, that is, the positions of the upper rotary shaft 16 and the lower rotary shaft 24 are moved to the center side of the door body 1,
When the position of the shaft 26a of the coupling metal fitting 26 is moved from the vertical frame 6 to the front side and the position of the shaft 27a of the coupling metal fitting 27 is arranged close to the door body 1, the right end portion of the door body 1 is indicated by the arrow G. When pushed in the direction (front side), the door body 1 rotates clockwise about the rotation shaft 16, and the guide arm 28 causes the coupling metal fitting 27.
It rotates counterclockwise about the shaft 26a via a, and finally the rotary shaft 16 is guided by the upper rails 9a and 9b to be positioned at 16 'and the guide arm 28 is positioned at 28'. . A force is applied in the direction opposite to arrow G. That is, when a force is applied in the direction of the arrow G ', the door body 1 operates in the opposite manner to the above and is closed.

Also in this case, the dead space for opening / closing surrounded by the locus 34 on the side surface of the door body 1 and the locus 35 on the right end of the door body 1 is very small.

As described above in detail, the opening / closing direction of the door body 1 and the opening / closing of the door body 1 are required depending on the mounting positions of the rotary shaft 16 and the lower rotary shaft 24, the dimensions of the fittings 26, 27, and the mounting position. Dead space, door body 1 when opened

In the first embodiment, the one-door opening device has been described, but in this embodiment, an automatic opening / closing double door opening device will be described. Needless to say, when the two doors are automatically operated, the same operation as described above can be performed. Further, the automatic operation described below can also be applied to the single-door opening device.

However, it will be explained below that one condition is necessary for the automatic operation described here.

The applied force of the automation device is P along the upper rails 9a and 9b (see FIG. 6). This force P passes through the rotary shaft 16
In addition to the door body 1, if the shaft 27a is on the line 36 connecting the lower rotary shaft 16 and the shaft 26a, the guide arm 28 is also on the line 36 and the force P is divided into the line 36. The force P'pushes the guide arm 28 in the direction of its axis via the shaft 27a, and only the component force P'provides a compressive force to the guide arm 28.
8 cannot be rotated.

Therefore, in order to automatically operate by the force such as P described above, the shaft 27a must be arranged at a position deviated from the line 36. Also in FIG. 7, the shaft 27a is arranged at a position deviated from the line 36 connecting the upper rotary shaft 16 and the shaft 26a (of course, as described above, the force is manually applied in the directions of the arrows F and G). In some cases, this condition is not necessary).

Next, the structure of the drive mechanism will be described with reference to FIG. 8 (also used in FIG. 3A).

As shown in FIG. 3 (a), the motor 37 is connected to the upper rail 9
This motor 37 is attached to the upper frame 7 above a and 9b.
A drive pulley 38 is attached to the output shaft of the above, and a driven pulley 39 of the same shape is pivotally supported by the upper frame 7 at a position at the same height as the drive pulley 38 above the right ends of the upper rails 9a and 9b. A belt 40 is stretched around the pulleys 38 and 39.

Further, a mounting bracket 41 is attached to the left main body 12 of the hanging portion, and turnbuckles 42, 4 are attached to both ends of the mounting bracket 41.
Both ends of the belt 40 are attached via 2 so that the tension can be adjusted.

Further, the upper belt 40 is attached to the right-hand door suspension body 12 via a belt attachment fitting 43.

In addition, as shown in FIG. 3, the drive mechanism and the door suspension 2 are
It is covered by the decorative plates 29 and 30.

The operation of this drive mechanism will be described. When the drive pulley 38 is rotated by the motor 37 in the direction of the arrow 44, the lower belt 40 causes the turnbuckle 42, the mounting bracket 41, the door suspension body 12, and the rotary shaft 16 to rotate. Through the left door body 1
Is applied with the force P described in FIG. In addition, similarly, the upper belt 40 includes the belt mounting bracket 43 and the main body 1 of the hanging part.
2. A force in the direction opposite to the force P described in FIG. 6 is applied to the right door main body 1 via the upper rotary shaft 16.

The door main body 1 on the left side (see FIG. 6) is the upper rotary shaft 16 of the force P.
The guide arm 28 is rotated clockwise through the shaft 27a by the component force P ″ in the direction of the line 45 that connects the shaft 27a with the shaft 27a.
Finally, the rotary shaft 16 is at 16 'and the guide arm 28 is at 2'.
8 ', the door body 1 is orthogonal to the upper rails 9a, 9b.

It should be noted that when the motor 37 is rotated in the reverse direction, it operates in the opposite manner to close the door body 1.

It goes without saying that the operation of the door body 1 as shown in FIG. 7 is the same as that in FIG.

Thus, the left and right door bodies 1 operate symmetrically with respect to the intermediate portions of the vertical frames 6 and 6 to be opened and closed. For example, FIG. 11 shows the operation shown in FIG. 7 symmetrically with respect to the central portions of the vertical frames 6, 6.

If the motor 37 is automatically or remotely operated, the door body 1 is automatically operated.

As described above in detail, in the second embodiment,
In addition to the effects described in the first embodiment, there is an effect that automation of door opening / closing can be easily performed without affecting the appearance.

[Effects of the Invention] As described in detail above, the present invention provides a door body having an upper frame and an upper frame on an eccentric vertical axis of rotation and an upper frame and a lower frame on a lower frame, and the upper frame. The main body of the hanging part to be supported, at least two guide doors that are pivotally supported by the main body of the door and are guided to roll on the upper surface of the upper rail attached to the upper frame, and the door hanging below the outer guide door.
