The frame chair seat has a pair of side ropes via a pair of foot side frame chair seat suspension chains and a frame chair seat suspension chain side rope connection hook, a pair of head side frame chair seat suspension chains and a chain connection hook. And is suspended by a metal head side chain. The side rope is connected to the upper fulcrum on the head side and the lower fulcrum on the foot side, and both ends of the metal head side chain are connected to a pair of upper fulcrum on the head side. A plane perpendicular to the straight line that passes through the midpoint of the straight line connecting the two points on the pair of head side upper fulcrum passes through the midpoint of the straight line that connects the two points on the pair of foot side lower fulcrum. And this plane is perpendicular to the ground. At the center of the metal head-side chain, a cylindrical head-mounting frame made of steel pipe is placed through the metal head-side chain. The head side frame chair seat hanging chain is connected by a chain connecting hook. The backrest fixing chain is connected to the horizontal position of the double-side frame chair seat hanging chain by a chain connecting hook, and the backrest fixing cylindrical tube is disposed through the backrest fixing chain. The backrest is fixed to the cylindrical head-mounting frame and the backrest-fixed cylindrical tube. The frame chair seat is composed of four seat frames, four seat frame joints, an arbitrary number of seat lateral bands and seat longitudinal bands. Four seat frames made of steel pipe are connected to a rectangle by four seat frame joints with hooks. A hook attached to each seat frame joint is connected to a pair of foot side frame chair seat suspension chains and a pair of head side frame chair seat suspension chains. The arbitrary number of seat transverse bands and seat longitudinal bands are bent at both ends of a band made of a flexible material such as a fabric, and the seat band stitching portion is sewn to create a seat frame loop. The seat frame is passed through the seat frame loop, and the seat lateral band is arranged side by side in the lateral direction of the rectangular frame made of the seat frame, and the seat longitudinal band is arranged in the longitudinal direction. The overlap between the lateral seat band and the longitudinal seat band is arranged so that the adjacent ones are alternately up and down. When storing the frame chair seats, remove the pair of frame chair suspension chain side rope coupling hooks from the side ropes and attach them to appropriate positions on the metal head side chain, and fold the seat frame and backrest so that they overlap. To do. A 4-fulcrum hanging chair with the above characteristics. The simple cloth hammock main body is suspended by a pair of simple cloth hammock chains via a flexible polymer resin protective hose. Both ends of one simple cloth hammock chain are connected to a pair of foot side lower fulcrums, and both ends of the other simple cloth hammock chain are connected to a pair of head side lower fulcrums. The two foot side lower fulcrum points and the two head side lower fulcrum points are on the same horizontal plane, and the plane perpendicular to the straight line passing through the midpoint of the straight line connecting the two foot side lower fulcrum points is the pair of heads. It is the same as the plane perpendicular to the straight line passing through the midpoint of the straight line connecting the two lower fulcrum points, and this plane is perpendicular to the ground. The base cloth of the simple cloth hammock body is a single rectangular cloth. Bend both ends of the base fabric and sew along the stitching line. Install the simple cloth hammock chain through the simple cloth hammock retaining ring. A 4-fulcrum hanging hammock with the above characteristics.
