Description

Technical Field

[0001] This utility model belongs to the field of folding chair technology, and specifically relates to a folding leisure chair. Background Technology

[0002] As an innovative furniture design, the folding recliner provides a convenient, comfortable, and multifunctional seating solution, and is widely used in various indoor and outdoor settings. However, traditional folding recliners are connected by hinges, which leads to problems such as unevenness, the hinges easily pinching hands when folding, deformation of supporting components due to severe local stress during use, and inconvenient removal and replacement of the chair cover.

[0003] A search revealed that the prior art patent announcement number CN 202618997 U describes a folding recliner, which primarily addresses the problem of head drooping in existing recliners, causing extreme discomfort and affecting rest quality. This folding recliner mainly consists of a folding frame and fabric mounted on it. The folding frame comprises a faceplate and a support hinged to it. A support frame is also mounted on the faceplate. This support frame, acting as a load-bearing component, directly contacts the base frame. Uneven stress on the support frame can easily cause deformation, affecting the recliner's lifespan.

[0004] A search revealed a multi-functional folding recliner with prior art authorization announcement number CN 205432888 U, comprising a base, armrests, support rods, a seat surface, and a footrest tube; the armrests are respectively hinged to both sides of the upper end of the base; the foldable support rods are respectively hinged to the base and the armrests; the footrest tubes are installed at the lower end of the support rods and are hinged to the support rods; the seat surface is respectively fixed to the support rods and the footrest tubes; the base is connected to the footrest tubes via a telescopic rod; the seat surface of this recliner is fixed to the support rods and the footrest tubes via elastic ropes, making it difficult to replace and clean.

[0005] A search revealed a folding recliner with prior art patent publication number CN 108887969 A, comprising a folding frame and fabric mounted on the folding frame. The folding frame consists of a cover for mounting the fabric and a support rotatably mounted on the cover. Armrests are provided on both sides of the cover, and a seat frame is provided in the middle of the cover. A support part that contacts the ground is integrally provided on the seat frame. When the recliner is folded, the support part contacts the ground, and the cover folds inward, shifting the center of gravity of the recliner above the support part, making the recliner stand upright on the ground. The armrests of this recliner are made of ordinary rectangular tubes, which are too narrow to be suitable for resting the arms and are also not ergonomic.

[0006] A search revealed a folding recliner with prior art authorization announcement number CN 201533682 U, which consists of three main parts: a main body, a support part, and a connecting part. The main body comprises a movable rod, a crossbar, a backrest rod, a seat rod, and a seat cushion. The rear support leg, the front support leg, and the chair leg connector are riveted together with steel rivets, and the support part can move in a circular motion. The angle of the chair leg connector is the same as the angle of the rear support leg and is fixed. The armrest rod is connected with steel rivets and can rotate in a circular motion with the chair leg connector. The semi-circular rotation of the armrest rod can move the armrest back and forth, thereby driving the backrest rod to move up and down. The recliner is connected by hinges, and there is a height difference when it is laid flat. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a folding lounge chair. A novel rotating connector allows the legs to rotate smoothly from the bottom support tube. The absence of height difference between the connectors on both sides ensures a more level chair and avoids the problem of fingers being pinched by the hinges during folding. A pad cover prevents the supporting round steel from directly contacting the bottom support tube, solving the problem of deformation caused by excessive stress on the supporting round steel. The armrests feature a streamlined design that fits the arm size and optimizes posture, making it more ergonomic. The chair cover uses Velcro closures and can be fitted with pillows, seat cushions, and leg rests according to usage needs, making it more flexible in different scenarios. The Velcro closure also makes the chair cover easy to remove, clean, and replace.
