Description

BACKGROUND OF THE INVENTION

1. Technical Field

The invention belongs to the technical field of chairs, and particularly relates to a rotary hanging chair.

2. Description of Related Art

Swing chairs are common leisure furniture in courtyards, gardens and amusement parks and are extremely popular in amusement parks because of their attractive appearance and romantic atmospheres created by them during use. When users sit on the swing chairs to rest in the shade, the swing chairs can by pushed to swing to allow users to feel comfortable and cool. Traditional swing chairs can only swing forwards and backwards like a swing and have a relatively constant angle that cannot be adjusted freely during use. In addition, existing swing chairs are provided with two symmetric supports, an adjustment device and a suspension rod are connected to the end of each support, and a shelter is assembled between the two adjustment devices. However, such swing chairs can only be used outdoors due to their large size. In addition, such swing chairs have a complicated structure, and it is difficult to assemble the ends of the supports, the adjustment devices, the suspension rods and the shelter together, which makes the swing chairs inconvenient to assemble and disassemble and makes it time-consuming and strenuous to assemble and dissemble such swing chairs. Besides, such swing chairs are inconvenient to use and difficult to carry. So, traditional changing chairs can only swing forwards and backwards, have a constant swing angle in use, and have a direction that cannot be adjusted, thus failing to meet the requirement of users for angle adjustment, and users cannot have a good relax when sitting on the swinging chairs.

All components of the entire rotary hanging chair can be disassembled easily and can also be assembled conveniently and quickly.

Specifically, in this embodiment, the support frame comprises a body composed of two support tubes 12, two connecting members 13 and a horizontal tube 14, a bearing 18, a connecting shaft 110, a protective cover 15, and locking plugs 11. Wherein, each of two ends of the horizontal tube 14 is connected to a lower end of one support tube 12 through one connecting member 13, and upper ends of the two support tubes 12 are connected to two ends of the cushion 17; and the horizontal tube 14 is rotatably connected to a top of the base assembly, so that the entire support frame is able to rotate within 360° with respect to the base assembly.

For the purpose of rotation, the bearing 18 is disposed in the middle of a bottom surface of the horizontal tube 14, and the connecting shaft 110 in the middle of the bearing 18 is connected to the base assembly. Specifically, the connecting shaft is mounted on the base assembly, the entire support frame rotates with respect to the connecting shaft through the bearing, and then, the cushion 7 is driven to rotate by any angle.

In a preferred implementation, the connecting members 13 and the horizontal tube 14 are welded together, and the lower ends of the support tubes 12 are detachably connected to the connecting members 13. Slots are formed in upper ends of the connecting members 13, and the support tubes 12 are inserted into the slots, so that the horizontal tube 14 and the horizontal tubes 14 are assembled and fixed together, and the support tubes 12 and the horizontal tube 14 can be assembled and disassembled quickly. To improve the firmness of the structure, the horizontal tube 14 may be a square tube, and the support tubes 12 may be round tubes.

The locking plugs 11 are disposed around the upper ends of the support tubes 12, and suspension ropes at two ends of the cushion 17 are fixed to the locking plugs 11 on the two support tubes 2 respectively, so that the cushion 17 can swing forwards and backwards with respect to the support tubes 12 like a swing. The cushion 17 is designed with a backrest, so that users can feel more relaxed and comfortable when sitting on the rotary hanging chair. The two ends of the cushion are connected to an upper end of the support frame through adjustment belts, and the length of the adjustment belts is adjustable. By adjusting the length of the adjustment belts, different users can sit on the rotary hanging chair more comfortably.

The bearing is preferably a tapered roller bearing capable of steering under pressure, so that noise and shaking are smaller, and the stability is high.

In this embodiment, the protective cover 15 is disposed around the horizontal tube 14, clamping grooves are formed in two symmetrical ends of the protective cover 15, and the protective cover is clamped in the middle of the horizontal tube through the clamping grooves and covers a joint of the horizontal tube 14 and the bearing 4.

When the rotary hanging chair is to be unfolded, the leg tubes 112 are pulled outwards and upwards to gradually form a tapered shape with the support shaft 111 as the center, the connecting tubes 113 are driven to be horizontal gradually until the base assembly is completely unfolded, the connecting shaft is inserted into the support shaft, and at this moment, users can sit on the rotary hanging chair. When the rotary hanging chair is to be folded, the leg tubes 112 are pushed inwards and downwards, the leg tubes 112 and the connecting tubes 113 move close to the axis of the support shaft 111 gradually, the multiple leg tubes 112 are gathered together to the center to fold the base assembly, and at this moment, the three-dimensional space occupied by the rotary hanging chair is reduced.

To ensure that the rotary hanging chair can be moved and stored conveniently, the leg pads 115 are designed into universal structures. Specifically, upper ends of the leg tube sleeves 114 are disposed around lower ends of the leg tubes 112 (preferably, the upper ends of the leg tube sleeves 114 are disposed around notches in the lower ends of the leg tubes 112), spherical grooves 1141 are formed in the lower ends of the leg tube sleeves 114, and balls on the leg pads 115 are embedded in the spherical grooves 1141. Through the spherical design, the leg pads can be flexibly adjusted to any angles.

Because the leg tube connecting seat 19, the support shaft 111 and the connecting shaft 110 are key parts that are assembled together, the leg tube connecting seat decorative cover 18 is disposed to cover the support shaft 111, so the support shaft 111 is prevented from being exposed, and the appearance is more beautiful and simpler.

To increase the support capacity on the ground, the leg pads 115 are in the shape of a disc, and the balls are disposed on the discs. The leg tubes 112 and the connecting tubes 113 are preferably round tubes.
