Claims (1)

[Scope of Claim for Utility Model Registration] (1) A hanging door along the opposite end of either one of the hanging side frame and hanging door body that constitute a swinging door or a folding door. A first convex guard member having a first arc-shaped convex surface centered on the rotation axis of the rotational support portion of the body is attached, and the other opposing end of the hanging side frame and the hanging door body. a first concave guard member having a first circular concave surface concentric with the first circular convex surface and spaced apart from the first circular convex surface with a slight gap, and A folding door characterized in that, when the door is not bent, a non-overlapping portion of a predetermined size is provided on both sides of a portion where the first arcuate convex surface overlaps with the first arcuate concave surface. Department structure. (2) Out of the plurality of door bodies that make up the folding door, two adjacent door bodies that have a bent part between them are connected along the opposite end of one of them. The second center is centered on the rotation axis of the hinge coupling member.
A second convex guard member having an arc-shaped convex surface and whose center is displaced by a predetermined dimension toward the bending recess when the door is not bent is installed, and the other of the two adjacent door bodies is installed. a second concave guard member having a second arc-shaped concave surface concentric with the second arc-shaped convex surface and spaced apart from the second arc-shaped convex surface with a slight gap; installed, and configured such that when the door is not bent, the angle formed by both side surfaces of the second convex guard member and the second concave guard member on the bent protruding side is a predetermined angle or more. Characteristic folding structure of the door. (3) Along the opposite end of either the hanging side frame or the hanging door body that make up the folding door, centered on the rotation axis of the rotation support part of the hanging door body. 1st
A first convex guard member having an arc-shaped convex surface is installed, and is concentric with the first arc-shaped convex surface along the opposite end of the other of the hanging side frame and the hanging door body. A first concave guard member having a first arc-shaped concave surface spaced apart from the first arc-shaped convex surface with a slight gap is attached, and when the door is not bent, the first arc-shaped convex surface A non-overlapping portion of a predetermined size is provided on both sides of the overlapping portion with the first arcuate concave surface in the door, and furthermore, a non-overlapping portion of a predetermined size is provided on both sides of the overlapping portion with the first arcuate concave surface, and further, a phase member having a bent portion between both of the plurality of door bodies constituting the door. It has a second arc-shaped convex surface centered on the rotation axis of the hinge coupling member that connects both door bodies along the opposing side end of either one of the two adjacent door bodies, and the non-folding surface of the door. A second convex guard member is installed in which the center is displaced by a predetermined dimension toward the bending depression side when the door is bent, and the second convex guard member is mounted along the other opposing side edge of the two adjacent door bodies A second concave guard member having a second arc-shaped concave surface concentric with the arc-shaped convex surface and spaced apart from the second arc-shaped convex surface with a slight gap is attached, and when the door is not bent. The folding structure of a door according to the invention, wherein the angle formed by both side surfaces of the second convex guard member and the second concave guard member on the protruding side of the fold is greater than or equal to a predetermined angle. (4) The distal ends of a pair of plate members each having an arcuate distal end are overlapped vertically, a bearing is interposed in the overlapping part, and the rotational axis of the overlapping part is aligned with the second convex guard member.
