Description

Technical Field

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

[0002] Currently, most lounge chairs are assembled using screws. Screw assembly presents several problems: 1. Users may misalign holes or strip screws during self-assembly, leading to assembly failure or frame deformation and uneven stress after assembly; 2. Users cannot determine whether screws are tightened or loose during connection; 3. Long-term outdoor use may cause screw corrosion, affecting structural stability; 4. Multiple screw types are easily lost or confused, increasing maintenance difficulty; 5. Exposed screws affect the overall aesthetics. Chinese Patent Application No. 2024109058181 discloses a lounge chair and its assembly method. The frame assembly, consisting of the top frame, multiple connecting rods, legs, support frame, and fasteners, can be disassembled when needed. For example, when transporting the lounge chair from one location to another, it can be disassembled. The space occupied by the disassembled components is smaller than that occupied by the assembled chair, thus reducing transportation costs. However, this method requires many screws for assembly, resulting in the aforementioned drawbacks. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a leisure chair structure that has fewer screws for assembly, good stability, simple structure, and low cost when in use; and is easy to disassemble and store when stored, with fewer steps, making it practical and portable.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a leisure chair structure, including two armrests and a seat frame and a backrest frame disposed between the two armrests. The front and rear parts of the seat frame are inserted and connected to the armrests. A rear support rod is detachably connected between the two armrests. The lower part of the backrest frame is rotatably connected to the seat frame and the backrest frame is supported on the rear support rod.

[0005] When disassembling and storing the lounge chair, both armrests are separated from the seat frame and backrest frame. The backrest frame and seat frame are folded together, allowing the armrests, backrest frame, and seat frame to be stacked together for packaging, significantly reducing storage volume, making it easier to carry and reducing transportation costs. To unfold the lounge chair for use, insert the two armrests into the left and right sides of the seat frame respectively, then rotate the backrest frame backward to support it on the rear support rod. At this point, the lounge chair is fully unfolded, stable, and reliable. No screws are used during the disassembly and assembly of the lounge chair, thus reducing the number of screws used throughout the chair and lowering the risks associated with screw connections.

[0006] The leisure chair described in this patent application has fewer screws when in use, resulting in good stability, simple structure, and low cost; when stored, it is easy to disassemble, requires fewer steps to store, and is practical and portable.

[0007] Preferably, the seat frame and armrests are connected by a horizontal insertion mechanism and a vertical insertion mechanism. The horizontal insertion mechanism inserts the seat frame and armrests from the left and right sides, allowing them to rotate relative to each other. The vertical insertion mechanism inserts the seat frame from top to bottom.

[0008] The lateral insertion mechanism inserts from the left and right sides, allowing the seat frame and armrests to rotate longitudinally relative to each other. This enables the longitudinal insertion mechanism to insert from top to bottom, achieving reliable positioning between the two armrests and ensuring the stability of the entire lounge chair.

[0009] Preferably, the transverse insertion mechanism includes a insertion post and an insertion base. The insertion base is provided with a transverse insertion hole, and a locking block is provided in the transverse insertion hole.

The width of the opening of the snap-fit ​​groove is smaller than the width of the widest part of the snap-fit ​​component.

[0012] The longitudinal insertion mechanism is used for connecting the seat frame and armrests. As the seat frame and armrests rotate relative to each other, the locking block moves circumferentially along the locking groove. Simultaneously, the snap-fit ​​component inserts from top to bottom into the snap-fit ​​groove on the snap-fit ​​seat. The snap-fit ​​component is longitudinally supported and limited within the snap-fit ​​groove, ensuring reliable support. The opening width of the snap-fit ​​groove is smaller than the widest part of the snap-fit ​​component to prevent the snap-fit ​​component from disengaging from the snap-fit ​​groove, ensuring the stability of the lounge chair.

[0014] The horizontal and vertical insertion mechanisms are positioned in different locations to enable various assembly methods, making it flexible and convenient.

[0015] Preferably, the chair frame includes two seat posts and a front seat plate and a rear seat plate connected between the two seat posts, both of which are connected to armrests.

[0016] The frame structure, consisting of the front seat, rear seat, and two seat posts connected together, provides good stability. Both the front and rear seat panels are connected to the armrests to ensure stable support.

[0017] Preferably, the backrest frame includes two backrest rods and an upper backrest crossbar and a lower backrest crossbar connected between the two backrest rods, with the lower part of the backrest rods rotatably connected to the chair seat frame.

[0018] The frame structure, consisting of an upper backrest crossbar, a lower backrest crossbar, and two backrest bars connected together, provides excellent stability. The lower part of the backrest bars is rotatably connected to the seat frame for easy storage and unfolding.

[0019] Preferably, a backrest bracket is provided between the backrest frame and the rear support rod. The backrest bracket has a front slot and a rear slot. The front slot is inserted into the backrest frame, and the rear slot is inserted into the rear support rod.

[0020] When the backrest is unfolded and in use, the backrest brackets position the backrest and ensure stable support.

[0021] Preferably, the handrail has an inverted U-shaped structure, with the rear side of the handrail tilting backward from top to bottom.

[0022] The armrests provide support for the entire lounge chair, and the back of the armrests slopes downwards and backwards, which helps to improve the stability of the armrest support.

[0023] As a preferred option, a seat cushion is installed on the seat frame, and a backrest cushion is installed on the backrest frame.

The snap-fit ​​component 16 is provided with a T-shaped snap-fit ​​post 29, and the snap-fit ​​groove 17 has a T-shaped structure. The snap-fit ​​post 29 is snapped into the T-shaped snap-fit ​​groove 17. Both the snap-fit ​​post 29 and the snap-fit ​​groove 17 gradually decrease in size from top to bottom, thereby limiting the longitudinal support of the snap-fit ​​component 16 within the snap-fit ​​groove 17; or, the lower end of the snap-fit ​​groove 17 is closed, thereby limiting the longitudinal support of the snap-fit ​​component 16 within the snap-fit ​​groove 17. After the snap-fit ​​post 29 and the snap-fit ​​groove 17 are inserted and connected, longitudinal limiting can be achieved, thereby achieving reliable support for the chair seat frame 2. Moreover, after the snap-fit ​​post 29 and the snap-fit ​​groove 17 are inserted, reliable lateral limiting is achieved, preventing the chair seat frame 2 and the armrest 1 from laterally separating.

[0055] A seat cushion 18 is installed on the seat frame 2, and a backrest cushion 19 is installed on the backrest frame 3. The seat frame 2 includes two seat posts 20 and a front seat plate 21 and a rear seat plate 22 connected between the two seat posts 20. Both the front seat plate 21 and the rear seat plate 22 are connected to the armrests 1. Insertion seats 10 are fixedly connected to both ends of the front seat plate 21, and snap-fit ​​seats 15 are fixedly connected to both ends of the rear seat plate 22. The backrest frame 3 includes two backrest rods 23 and an upper backrest crossbar 24 and a lower backrest crossbar 25 connected between the two backrest rods 23. The lower part of the backrest rods 23 is rotatably connected to the seat frame 2. Supports are fixedly connected to both seat posts, and the lower part of the backrest rods 23 is rotatably connected to the supports. A backrest holder 26 is provided between the backrest frame 3 and the rear support rod 5. The backrest holder 26 has a front slot 27 and a rear slot 28. The front slot 27 is inserted into the backrest frame 3, and the rear slot 28 is inserted into the rear support rod 5. The backrest holder 26 is fastened to the backrest rod 23, or the backrest holder 26 is fastened to the rear support rod 5. In this embodiment, the backrest holder 26 is fastened to the backrest rod 23.

[0056] When disassembling and storing the lounge chair, both armrests 1 are separated from the seat frame 2 and backrest frame 3. The backrest frame 3 and seat frame 2 are folded together. At this point, the armrests 1, backrest frame 3, and seat frame 2 can be stacked together for packaging, greatly reducing storage volume, making it easier to carry and reducing transportation costs. When unfolding the lounge chair for use, insert the two armrests 1 into the left and right sides of the seat frame 2 respectively, and then rotate the backrest frame 3 backward so that it supports itself on the rear support rod 5. At this point, the lounge chair is fully unfolded, stable, and reliable. No screws are needed during the disassembly and assembly of the lounge chair, thus reducing the number of screws used throughout the chair and lowering the risks associated with screw connections.

[0057] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
