Claims (1)

[Scope of Claim for Utility Model Registration] The upper side of a folding door, in which two door bodies are folded and unfoldably connected with a hinge, is attached to a movable hanging body slidably supported by an upper guide rail on four non-parallel sides. The lower part of the side of the folding door is connected to the movable guiding body slidably engaged with the lower guide rail via a non-parallelogram link mechanism, and the folding door is connected to swing open and close via a non-parallelogram link mechanism. When the folding door is movably connected and is in the unfolded and closed position,
The side part of the folding door is configured to overlap the outside of the opening side frame, and the movement locus of the side part of the folding door when the folding door moves from the unfolded and closed position to the folded open position is configured. The sliding folding door is configured such that the non-parallelogram link mechanism passes through an area that does not come into contact with the opening side frame. The suspension movable body is connected to a vertical plate that is flat in the sliding direction, a pair of front and rear supporting horizontal shaft rollers that are pivotally supported only on the outside of the vertical plate, and are bent and connected outward from the upper end of the vertical plate. and a pair of vertical axis rollers for steady rest pivotally supported on the upper side of the horizontal plate part, and the non-parallelogram link mechanism is disposed on the outside of the vertical plate, and the upper guide rail A utility model comprising a gate-shaped cross section in which a vertical axis roller for steady rest is fitted inside, and a support rail part for supporting the horizontal axis roller for support is provided in a cantilevered manner from the lower end of the outer plate part to the inside. A sliding folding door as set forth in the registered claims. The vertical plate is composed of an upper vertical plate that pivotally supports the roller, and a lower vertical plate suspended from the lower end of the upper vertical plate so as to be swingable in the sliding direction by a horizontal horizontal axis, and the lower vertical plate The sliding folding door according to claim 1, wherein the non-parallelogram link mechanism is disposed on the outside of the sliding folding door.
