Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a folding door that opens by pivoting one end to one vertical stile, moving the other end along the upper and lower frames, and bending the middle part.

(Prior Art) Japanese Patent Publication No. 61-4955 discloses a structure in which a handle is attached to the vertical stile at the center of a folding door, thereby reducing the range of movement of the hand when opening and closing the door.

(Problem to be Solved by the Invention) In the above-mentioned conventional technology, in order to improve operability, it is necessary to provide a space between the grip of one handle and the vertical stile so that a finger can be inserted with plenty of room. By providing this distance, when opening the folding door, that is, when opening the left and right doors connected by the center hinge etc. so that they overlap, the handles attached to the adjacent vertical frames will come into contact with each other. There was a problem in that the stiles could not be opened very close together, and therefore the width of the opening for people to pass through when opening the folding door could not be made very wide.
On the other hand, if the distance between the gripping part of the handle and the vertical stile is narrowed, it becomes difficult to grip one handle, resulting in poor operability.

The present invention aims to solve these problems.

That is, it is an object of the present invention to provide a folding door having a structure that allows a sufficient distance between the gripping part of one handle and the vertical stile, and also allows a wide opening when the folding door is opened.

(Measures to Solve the Problem) In order to achieve this object, the folding door according to the present invention has a handle for attaching the handle to the vertical stile on the center side of the folding door, and the handle is attached to the handle in the direction inward of the panel surface. It is rotatably mounted, and when the handle is oriented horizontally, the tip of the handle is located closer to the panel than the outside surface of the stile, and when the handle is oriented vertically, the tip of the handle is located outside the outside surface of the stile. The handle and attachment are characterized by having an engaging structure with the tool.

(Function) Since the present invention has the above-described structure, when one handle is oriented vertically, a sufficient distance can be maintained between the gripping part of the handle and the vertical stile, and when the handle is oriented horizontally, Since the tip of the handle can be positioned inside the outer surface of the stile, that is, on the panel side, the left and right door bodies can be brought close to each other when the folding door is open.
