In this case, there is an advantage that the opening can be almost fully opened without opening only one half of the opening like a sliding door. On the other hand, the use of Gremon tablets for locking allows the handle to be operated before the folding door is extended and closed before the rod reaches the predetermined position on the upper and lower frames. The misoperation of the glemon lock, such as the lock being left unlocked or the pulling of the handle after operating the handle, causes the rod or the locking member provided on the rod to abut the upper and lower frames, causing damage to them. There is a possibility that this may cause trouble.

[0004] The present invention has been made in view of such circumstances, and a problem to be solved is to make it impossible to operate the handle unless the folding door is extended and closed. Another object of the present invention is to provide an apparatus for preventing erroneous operation of a glemon lock of a folding fitting, which can eliminate the problem.

While the side of the intermediate connecting frame and the side of the partition panel face each other in series, when folded, the intermediate connecting frame and the partition panel escape from the upper and lower frames to the outdoor side, and these side surfaces are mutually connected. Attention is paid to the fact that the intermediate connection frame and the side surfaces of the partition panel are separated from each other in accordance with the opening and closing of the folding door when they are separated from each other so as to form an L-shape at or near a right angle. A trigger mechanism is installed on a rod operating portion of the glemon tablet installed on the connection frame that moves the rod up and down by the above-mentioned handle operation, and the trigger mechanism is controlled by moving the partition panel into and out of the intermediate connection frame. When the arm is separated from the intermediate connecting frame, the trigger mechanism locks the rod operating part and disables the operation of the handle, and the partition panel faces and faces the intermediate connecting frame. Only in the assembled state, the trigger mechanism releases the lock of the rod operating portion to enable the operation of the steering wheel. The frame is composed of a folding door that connects the left and right partition panels by rotatably disposing the frame and an intermediate connecting frame rotatably interposed in the middle in the width direction, and the upper and lower frames and the left and right vertical frames. The single or left or right folding door is suspended above and the traveling frame is movable in the in-plane direction by the guide of the opposing guide rails formed on the upper and lower frames, thereby enabling the folding door to be opened and closed. A folding door is provided with a door frame and an indoor side handle-operated glemon lock is installed in the intermediate connection frame, and a pair of two-way rods is lifted and lowered so that the two doors can be freely disengaged from the upper and lower frames. For folding fittings, A trigger mechanism is installed on the rod operating part of the lock, and when the intermediate connecting frame and the partition panel are in a rotating state, the trigger is projected sideways from the intermediate connecting frame to lock the rod operating part and perform the handle operation. On the other hand, when the intermediate connecting frame and the partition panel are in a series state, the trigger is immersed in the intermediate connecting frame by pressing the partition panel, thereby unlocking the rod operating portion and enabling the handle operation. This is a device for preventing erroneous operation of a foldable fitting of a folding fitting.

[0006] In addition to the above, the invention according to claim 2 provides:
The rotation of the handle, especially when locked and unlocked, has ample 180 degree rotation so that the handle is positioned within the width of the intermediate connection frame, due to the large stroke of the lock operation part of the gremone lock. In order to obtain a reliable and stable operation by simplifying the structure of the trigger mechanism and the relationship with the lock operating part as much as possible, the rod operating part of the Gremon lock is operated by the handle operating means. And a pair of opposing racks, each of which fixes the pair of bidirectional rod ends, and which can move up and down in the opposite direction by rotation of the pinion.
