Are known. And in the conventional one, a handle for opening and closing is provided on the door plate on the side opposite to the hanging side.

[0003]

However, since the door plate on the side opposite to the hanging side performs a relatively complicated motion when opening and closing, the operation of opening and closing the folding door by holding the handle is normal operation and the like. There is a big difference between the operation of opening and closing. Therefore, there is a problem that a feeling of strangeness is given when the opening / closing operation is performed.

Also in this type of folding door, a locking lock mechanism and the like are provided on a door plate having a handle, and a key is inserted into a key hole provided in the vicinity of the handle to perform a locking operation. The rod projects from the lower surface of the door plate and engages with a lock hole provided in the threshold of the opening. However, since the door plate of the anti-suspension source that has the handle is supported by the side frame member of the opening through the door plate on the suspension source side, it is not possible to position it due to dimensional error or rattling of hinges etc. Misalignment is likely to occur. Therefore, it is likely that the rod of the lock mechanism cannot properly engage with the rod engagement hole.

An object of the present invention is to solve such a problem.

[0006]

The present invention takes the following means in order to achieve such an object.
That is, the folding door according to the present invention comprises a door plate on the hanging side which is hinged to the opening, and a door plate on the anti-hanging side which is hinged to the tip edge of the door plate. It is characterized in that a handle for opening and closing is provided on the side door plate.

In order to reliably perform the lock operation, it is desirable to provide the lock mechanism on the door plate on the hanging side.

[0008]

Since the handle provided on the door plate on the hanging base side makes an arc motion centering on the hinged part of the door plate on the hanging base side, the handle for performing a complicated motion as in the prior art is operated with the hand. than,
The operability will be good.

In addition, when the lock mechanism is provided in the handle portion, the rod of this lock mechanism also only makes an arc motion, so errors are accumulated and the rod is provided at the opening edge portion of the rod and the opening portion in the closed position. In addition, it is possible to solve the problem that the relative position with respect to the rod engaging hole or the like is changed.
