For example, it is performed by pressing the fourth door toward the third door, and in this case, the pressing force causes the fourth door and the third door to move in a vertical direction of a straight line connecting the swing axis centers thereof. They are folded at equal angles with respect to the bisector. However, the second
The pivotal portion between the door and the third door may move immediately due to this pressing force, or may move after the third door and the fourth door are in a superposed state. An angle formed by the door and the second door, an angle formed by the third door and the fourth door,
Do not have the same angle. Therefore, the folding work cannot be performed smoothly. On the contrary, when the folded state in which the four sheets are superposed is changed to the unfolded state, the angle formed by the first door and the second door, the third door, and the fourth door in the middle of unfolding. The angle formed by does not match, and the four doors are not reliably interlocked and folded. Even if the number of doors is three, the folding and unfolding work cannot be performed smoothly.

Therefore, an object of the present invention is to provide a folding door that can be reliably opened and closed by interlocking a plurality of doors and is excellent in design.

[Means for Solving the Problems]

In order to achieve the above object, the folding door according to the present invention comprises:
Plural doors suspended from the upper frame of the frame are pivotally connected to adjacent doors so that they can be displaced between a developed state where they are on the same straight line when seen in a plan view and a folded state where they overlap each other. A folding door provided with a hinge to the upper edge and / or lower edge side of the door; and a mounting piece to which the hinge is attached to the door next to each other,
A pair of pivotally connecting gears that mesh with each other and are arranged in two stages in the vertical direction via a neck, and the gearing of the pivoting is provided as an upper frame of the frame and / Or it is stored in the lower frame.

[Action]

In the unfolded state, if one of the adjacent doors is pressed toward the other door, the gear part of the pivot connection of one door and the gear part of the pivot connection of the other door are mutually Because they are in mesh
The two doors are surely interlocked and oscillate at the same oscillating angle to be folded, and conversely, in the folded state, one of the adjacent doors is opposite to the other door. In this case, the two doors are surely interlocked with each other by pressing in the direction, and are swung at the same swing angle to be deployed.
