Claims

[Scope of utility model registration request]

One side of the outer link part of the opposing offset-type link part is fixed to both sides of the support stay part, and the frame-shaped link formed by attaching the opening/closing stay part to the other side is connected so as to be bendable to each other at the offset-type link part. , the front part of the outer link part, the support stay part, and the opening/closing stay part in the closed position is formed into a convex cylindrical surface centered on the connecting hole provided in the outer link part, and the connecting hole is surrounded on the inside of the outer link part. Provide a recess that opens forward by bending.
The inner link part of the offset type link part forms a flexible tongue piece that slides into the recess, and has a protruding pin part on the outside of the rear part that fits into the connecting hole, and connects the outer link part and the support stay part. A concave cylindrical surface with a slightly larger diameter than the convex cylindrical surface is formed at the rear of the opening/closing stay part in the position, with the protruding pin part as the center, and when the protruding pin part is inserted into the connecting hole, the recess and the flexible tongue The frame-shaped link can be bent between the position where it forms a straight line due to side contact with the piece and the predetermined angular position where the adjacent front and rear opening/closing stay parts maintain overlap, and the opening/closing stay part is A closed cable that can be opened and closed, which is hinged to the link part with a bendable plastic sheet, and has a concave-convex engaging part that engages with the other outer link part in the closed position, and a snap that locks in the closed position. Dragon chain.
