As shown in FIGS. 3 and 4, the upper end of the base 31 is rotatably connected to the door frame 2 via bearings 61 and 62 and a shaft (first rotation shaft) 63 that faces in the vertical direction. . As shown in FIGS. 3 and 5, the lower end of the base 31 is connected to the door frame 2 via a bracket 64, a bearing 65, and an axis (first rotation axis) 66 that faces in the vertical direction.
Are rotatably connected to the The axis of the shaft 66 matches the axis of the axis 63. Therefore, the rotation arm 3 can rotate in the horizontal direction about the shafts 63 and 65. Moreover, the upper arm 32 can rotate in both the forward and reverse directions from the closed position parallel to the upper frame portion 21, and when rotated about 90 ° (slightly 90 ° in this embodiment) in the forward and reverse directions, The closed position is reached (see FIG. 8).

The door body 4 is used to open and close an entrance defined by the door frame 2 and the rotating arm 3, and as shown in FIGS. The intermediate portion in the direction is rotatably supported at the distal end of the upper arm 32 via a bearing 67, a support plate 68, and a shaft (second rotation shaft) 69 that faces in the vertical direction. As shown in FIGS. 1 and 5, an intermediate portion of the lower end portion of the door body 4 in the left-right direction is provided with a washer 70 and a vertical shaft (second rotation shaft) 71 at the distal end of the lower arm 33. It is rotatably supported. Accordingly, the door body 4 can be horizontally rotated in both the forward and reverse directions about the axes 69 and 71 with respect to the rotating arm 3. The rotation range of the door body 4 is the closed position (in this case, the rotation arm 3
Is also in the closed position. ) Is approximately 90 in both forward and reverse directions.
(See FIG. 8). A gap is formed between the door body 4 and the upper frame 21 in front of the upper arm 32. As shown in FIGS. 1 and 7, this gap is shielded by decorative plates 72 and 73. ing.

The door body 4 is connected to the upper frame 21 via the guide body 5 so as to be movable in the left-right direction (longitudinal direction of the upper frame 21) and rotatable in the horizontal direction. That is, as shown in FIGS. 6 and 7, the guide body 5 has a main body 51. On both sides of the main body 51, a pair of wheels 52, 52 are rotatably provided. This wheel 5
The guide members 5 are movably connected to the upper frame portion 21 in the left-right direction (longitudinal direction of the upper frame portion 21) by the rollers 2 and 52 being inserted into the guide portion 23 and rolling. Also, the main body 5
An upper end portion of a shaft (third rotation shaft) 53 whose axis is oriented in the up-down direction is connected to the central portion of 1. The lower end of the shaft 53 is rotatably connected to the upper end of the door body 4 via a washer 74. As a result, the door body 4 is supported by the upper frame portion 21 so as to be movable in the left-right direction and to rotate in the horizontal direction. It should be noted that the shaft 53 is connected to a position away from the shaft 68 in a direction opposite to the shaft 63. That is, axis 6
3 (66), 69 (71), and 53 correspond to one of the vertical frame portions 22.
(The right vertical frame portion 22 in FIG. 1) is sequentially arranged from the side to the other vertical frame portion 22 side. Of course, the shafts 63 (66), 69 (71), and 53 are arranged so that the door body 4 can move and rotate following the rotation of the rotation arm 3.

As shown in FIG. 2, a shaft 6 serving as a first rotating shaft is provided.
When the door device 1 is viewed from above with the door main body 4 in the closed position, the shafts 69, 71 and the shaft 53, which are the second rotation shafts, It is arranged so as to be located on one extending horizontal line L. As a result, as shown in FIG. 8, the door main body 4 can be opened and rotated in the forward and reverse directions from the closed position. By the way, in the conventional door device, one of the first to third rotating shafts is out of the line connecting the other two shafts, so that the door body is opened and rotated only in one of forward and reverse directions. I couldn't do that.

When the door body 4 can be opened and rotated in both forward and reverse directions from the closed position, the door body 4 can be pushed and opened in any case when moving in and out of the frame.
Therefore, it is possible to easily enter and exit the skeleton. Further, one door device 1 can be used as either a right-handed or left-handed door device. Therefore, it is not necessary to manufacture two types of door devices having different arbitrarily, and it is possible to reduce the manufacturing cost and the management cost by that much.

Next, another embodiment of the present invention will be described. 9 to 12 show a second embodiment of the present invention. In the embodiment 1A,
The pivot arm 3 is supported by the door frame 2 by a hinge 8 instead of the shafts 63 and 66 so as to be pivotable in the horizontal direction. The hinge 8 includes a mounting piece 81 fixed to each of the opposing surfaces of the one vertical frame portion of the door frame 2 and the base 31 of the rotating arm 3,
82, and a hinge body 83 disposed between the mounting pieces 81, 82. At both ends of the hinge body 83,
Cylindrical portions 84 and 85 are provided with their axes directed vertically, and hinge shafts 86 and 87 are inserted into each of the cylindrical portions 84 and 85. One end of the hinge body 83 is attached to the mounting piece 8 via one hinge shaft (one-way rotation shaft) 86.
1, and the other end is rotatably connected via the other hinge shaft (other direction rotation shaft) 87. When viewed from above, the hinge shafts 86 and 87 are arranged at symmetrical positions with respect to a horizontal line L orthogonal to the shafts 69 and 71 serving as the second rotation shafts and the shaft 53 serving as the third rotation shaft. Therefore, the pivot arm 3 pivots about the hinge shaft 86 between the closed position and the one open position (see FIG. 11),
It rotates about the hinge shaft 87 between the closed position and the other open position (see FIG. 12). When the rotation arm 3 rotates, the door body 4 opens and closes between the closed position and the two open positions.

An elastic member made of a coil spring is inserted into each of the cylindrical portions 84 and 85 between each inner peripheral surface and each of the hinge shafts 86 and 87. The first elastic member inserted into one of the tubular portions 84 urges the door body 4 toward the closed position via the rotating arm 3 when the door body 4 rotates from the closed position to the one open position. Then, the turning arm 3 and the door body 4 are returned to the closed position. The second elastic member inserted into the other cylindrical portion 85 biases the door body 4 toward the closed position via the rotating arm 3 when the door body 4 is rotated from the closed position to the other open position. Then, the turning arm 3 and the door body 4 are returned to the closed position. Therefore, in the door apparatus 1A, it is not necessary to close the opened door body 4 by hand. That is, the door device 1A is a semi-automatic door that can automatically rotate the opened door body 4 to the closed position. The other configuration is the same as that of the first embodiment.

FIG. 13 shows a third embodiment of the present invention. In a door device 1B according to this embodiment, a rotating arm 3 and a door body 4 are provided on both left and right sides in one door frame 2. And a pair of guide bodies 5 are arranged. Each rotating arm 3 is rotatably connected to the door frame 2 via the shafts 63 and 65, but may be rotatably connected to the door frame 2 using the hinge 8.

In this door apparatus 1B, the opening of the frame can be greatly opened by simultaneously rotating the two door bodies 4, 4 to the open position. When opening the door bodies 4, 4, they may be rotated to the open position on the same side of the skeleton, one of the door bodies 4 is rotated to a closed position inside the skeleton, and the other door body 4 is rotated. May be rotated to the closed position outside the frame. Further, in the door device 1B, since the rotating arm 3, the door main body 4, and the guide body 5 can be shared, the manufacturing cost of the door device 1B can be reduced.

FIG. 14 shows a fourth embodiment of the present invention in which the embodiment shown in FIG. 13 is modified. In the door device 1C of this embodiment, two stoppers S1 and S2 are provided. Is provided. One stopper S1
The opening of one door body 4 is prevented from rotating toward the inside of the body, and the other stopper S2 is configured to prevent the opening movement of the other door body 4 from opening to the outside. Therefore, one door body 4 is dedicated to the exit, and the other door body 4 is dedicated to the entrance. In this case, as is clear from the rotation trajectories of the door bodies 4, 4,
The dead space required for opening and closing 4 can be made very small.

It should be noted that the present invention is not limited to the above-described embodiment, and can be appropriately changed. For example, the first
Also in the embodiment, the first urging means for urging the door body turned to the one open position side to the closed position side, and the door body turned to the other open position side to the closed position side And a second urging means for urging the semi-automatic door in the same manner as in the second embodiment. In that case, the first,
The second biasing means may be provided separately, or may be shared by one coil spring or the like.
