AUTOMATIC DOOR DEVICE

Japanese Patent JP2016223167

A

PROBLEM TO BE SOLVED: To provide an automatic door device capable of readily opening/closing a door having a sliding door panel and a rotary door panel.SOLUTION: In an aspect of an automatic door device of the present invention, an opening/closing device includes a sliding door drive member fixed on a sliding door and being almost cross-shaped when seen in a planar view, a rotation switching part, and a posture regulating mechanism. The sliding door drive member includes a first extension part, a second extension part, a third extension part, and a fourth extension part. The rotation switching part presses the first extension part inward in an opening/closing direction, when outward driving force in the opening/closing direction is exerted on the second extension part after the sliding door is fully opened. The posture regulating mechanism includes a first regulating member and a second regulating member. The first regulating member exerts moment in a direction of rotation to close a folding door when the folding door is closed, by pressing the third extension part rearward. The second regulating member exerts moment in the direction of rotation to close the folding door when the folding door is closed, by pressing the fourth extension part forward.SELECTED DRAWING: Figure 4
