[Embodiment] Next, an embodiment of the present invention will be described with reference to FIGS. Reference numeral (1) is a swing door that opens and closes by a swing, and an advance / retreat door (2) that slides in and out of the swing door (1) is provided at the tip of the swing door (1). The revolving door (1) covers the arm (22) (23) via the cover (3).
It is fixed to the inner swivel shaft (24), and the swivel shaft (24) is pivotally supported by the fixed support column (3) via the supports (25) (26). A transmission gear (27) is further fixed to the swivel shaft (24), and meshes with a drive gear (28) fixed to the output shaft (9) of the drive motor (8). 27)
(28) is set to 1: 4, for example. The advancing / retreating door (2) has two upper and lower guide rollers (11) (11) (12).
It is supported by (12) and is driven by a nut (29) fixed to the door (2) and a screw (30) screwed to the nut (29). The screw (30) is rotatably supported by the arm (22), and a bevel gear (31) is fixed to the tip of the screw (30). The bevel gear (31) is fixedly installed in the fixed column (3). Broken bevel gears (32)
Meshes with. The interrupting bevel gear (32) is set to interrupt at 90 degrees as shown in FIG.
The advance / retreat distance is set by the ratio between the bevel gear (31) and the discontinuous bevel gear (32) and the pitch between the nut (29) and the screw (30). When the advancing / retreating distance is required to be 30 cm, the pitch of the nut (29) and the screw (30) is set to 10 cm, and the bevel gears (31) (32) are set to 12: 1.

In the above embodiment, first, when the drive motor (9) is operated with the door (2) shown in FIG. 3 (a) and the output shaft (9) is rotated counterclockwise, the gear (28 ) (27)
As a result, the turning shaft (24) rotates to the right, and the turning door (1) also turns to the right. Here, the screw (30) rotates because the bevel gear (31) rolls on the discontinuous bevel gear (32), and the advancing / retreating door (2) moves to the third position by the nut (29) and the screw (30).
It is drawn into the revolving door (1) as shown in FIGS.
When the swivel door (1) reaches 90 degrees, the intermittent bevel gear (32) is interrupted as shown in FIG. 2 (b), the screw (30) is not driven, and the retractable door (2) is not retracted any more. Only the swivel door (1) turns. Here, when the drive motor (8) is rotated in the reverse direction, the swing door (1) is rotated in the opposite direction, and when it reaches 90 degrees, the intermittent bevel gear (32) meshes with the bevel gear (31) and the screw (30) is driven. And the retreat door (2) is the swivel door (1)
It is pushed out of and returns to the original closed state.

In the above embodiment, the forward / backward door (2) is retracted when the revolving door (1) turns right, but the invention is not limited to this, and it may be retracted when turning left, and in this case, there is a break. The attachment position of the bevel gear (32) may be changed, the nut (29) and the screw (30) may be reverse-threaded, and the rotation direction of the output shaft (9) of the drive motor (8) may be reversed. When the entire door is long, casters may be attached to the lower surface of the tip of the revolving door (1).

[Effect of the Invention] Since the present invention is configured as described above, even in a narrow space, it is possible to obtain a frontage up to twice that space,
Since there is no space in the past and a sufficient frontage cannot be secured, the swing door can be installed in a place where the swing door cannot be used, and the swing door can be used in a wider range. Furthermore, since the forward / backward movement mechanism is simple, it is robust and is not easily damaged, and the timing of turning and forward / backward movement is accurate. Furthermore, since the forward / backward movement is performed using nuts and screws, the forward / backward movement door can be opened and closed. It has the effect that it does not move even if it is pushed or pulled from the outside.
