Claims (1)

[Scope of utility model registration request] A hinge post is arranged vertically between a pair of adjacent panels, and hooks protruding from the side edges of each panel are rotatably fitted into the hinge shafts formed on the left and right sides of the hinge post, respectively. In a folding door that is foldably connected via a hinge post and arranged between upper and lower rails, the hinge post has a U-shaped horizontal cross section with tongues extending inward from the ends of both sides at a substantially right angle. is formed in such a shape that a substantially circular hinge shaft is formed at the tip of each tongue with a gap between them, and the horizontal cross section formed at the tip of the hook protruding from the side edge of each panel is C-shaped. The C-shaped portions of the two are rotatably fitted around the respective hinge shafts, and a notch is formed at the lower end of the hinge post by removing a portion extending from both hinge shafts to the tongue piece at a predetermined height. A cutout window is formed at the lower end of the hook by removing the C-shaped part so as to match this notch, and one side of the block to be fitted into the lower end of the hinge column is exposed to the above notch and cutout window, and the block A vertical hole is provided that passes through the vertical hole, and a vertically long elongated hole that communicates with the vertical hole is formed on one side exposed to the notch and the notched window, and a vertical bar that is inserted into the vertical hole so as to be able to move vertically. The operating lever protrudes from the side surface through a long hole, and protrudes from the inner wall surface of the vertical hole by a pull that fits into the left and right horizontal holes penetrated through the block so as to be orthogonal to the vertical hole. A ball is provided that is movable between the block and the position retracted from the inner wall surface, and on the outer surface side of both sides of the block there are springs in the horizontal hole and horizontal holes to prevent the ball from falling outward. A temporary fixing tape is pasted to cover the opening on the outside of the hole, and while the ball is in bone contact with the outside surface of the vertical bar due to the force of the spring, the bottom end of the vertical bar protrudes downward and attaches to the bottom of the lower rail. The ball moves up and down between the position where it fits into the recess provided in one place and the position where the lower end is retracted into the hinge column, and when the lower end of the vertical bar is retracted into the hinge column, the ball moves around the outer periphery of the vertical bar. A locking structure for a folding door in which the vertical bar is locked in this position by entering one locking groove, and the C-shaped lower end surface of the hook that fits into each hinge shaft is locked to the upper end of the block.
