Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to the field of outdoor auxiliary equipment or devices technology, specifically to a portable detachable reclining chair. Background Technology

[0002] Chairs are used in almost every aspect of life, and there are many different types available, especially portable outdoor chairs. However, most existing portable chairs focus on being foldable and easy to store, resulting in relatively lower levels of comfort. Those with higher comfort levels often fall short in terms of storage capacity and size. Outdoor portable chairs are commonly used for picnics, spring outings, and fishing. Especially for fishing, a simple sitting posture is often insufficient for anglers, and those who fish for extended periods often crave a reclining position. Therefore, developing a new type of chair that can be used for both sitting and reclining is essential for outdoor enthusiasts. Utility Model Content

[0003] To address the issue that existing portable outdoor chairs are limited to deformable storage and cannot solve the problem of lying down for rest, this application provides a portable detachable chair that can be used for both sitting and reclining. The chair can be switched between sitting, reclining, and fully detached storage states according to the user's needs. The entire chair can be installed without tools, has a small storage size, can be placed in a regular family car, and is highly portable.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] A portable, detachable reclining chair includes a detachably connected seat mechanism, two support mechanisms mounted below the seat mechanism for supporting the seat mechanism, and a backrest mechanism mounted above the seat mechanism at an angle α to the seat mechanism; the backrest mechanism is connected to the seat mechanism via a straight sleeve or a connecting bend to form a reclining chair or seat structure.

[0006] To simplify the structure, preferably, the seat mechanism includes two parallel horizontal bars, with a seat cloth slidably connected to the two horizontal bars.

[0007] To further enhance the comfort of the sitting posture, preferably, the seat mechanism also includes an armrest mounted on the horizontal bar, the armrest including an armrest body and a lockable sleeve for fixing both ends of the armrest body to the horizontal bar.

[0008] More preferably, the support mechanism includes a crossbeam, with support rods detachably connected to both ends of the crossbeam via branch pipes to form an H-shaped support structure. The lower end of the support rod is rotatably mounted with an adjustable-angle base, and the upper end of the support rod is connected to a horizontal rod via a connecting bend.

[0027] Example 1:

[0028] This embodiment provides a portable, detachable, reclining chair; see the instruction manual attached. Figures 1-4 As shown, it includes a detachably connected seat mechanism 1, two support mechanisms 2 installed opposite to the seat mechanism 1 for supporting the seat mechanism 1, and a backrest mechanism 3 installed above the seat mechanism 1 and forming an angle α with the seat mechanism 1; the backrest mechanism 3 is connected to the seat mechanism 1 through a straight sleeve 14 or a connecting bend 22 to form a recliner or seat structure.

[0029] Explanation of structure and working principle:

[0030] See the instruction manual appendix Figure 1 As shown, the backrest mechanism 3 and the support mechanism 2 are detachably mounted on the upper and lower parts of the seat mechanism 1, respectively, forming a configuration as shown. Figure 1 The seat structure is shown in the seated posture state. In this seated posture state, the angle α between the plane of the backrest mechanism 3 and the plane of the seat plate mechanism 1 determines the seat posture state. The angle α is achieved by the angle of the connecting bend 22.

[0031] In the reclining position, support mechanism 2 always provides support and is always installed at the bottom, although its installation position may vary. Figure 3 As shown, in the case of a reclining chair structure, the backrest mechanism 3 is connected to the seat mechanism 1 via a straight sleeve 14, forming a straight whole and constituting a structure for reclining. Two support mechanisms 2 are distributed at both ends of the structure, respectively installed on the backrest mechanism 3 and the seat mechanism 1, providing good support for the overall weight. The main structure of this embodiment is assembled from rods, straight sleeves 14, and connecting bends 22. By simply changing the assembly method and adjusting the connection positions between the structures, the state can be quickly changed, making it suitable for different application scenarios.

[0032] Example 2:

[0033] To simplify the structure, in this embodiment, the seat mechanism 1 includes two parallel horizontal rods 11, and a seat fabric 12 slidably connected to the two horizontal rods 11. The horizontal rods 11 are made of aviation aluminum tubes or thickened stainless steel tubes, and the seat fabric 12 is made of multi-layer fabric or breathable mesh structure.

[0034] To further enhance the comfort of the sitting posture, in this embodiment, the seat mechanism 1 also includes an armrest 13 mounted on the horizontal bar 11. The armrest 13 includes an armrest body and a lockable sleeve for fixing both ends of the armrest body to the horizontal bar 11. The lockable sleeve can be easily disassembled and fixed by using a bolt-locking structure to clamp the separate sleeves onto the horizontal bar 11; alternatively, it can be locked using a threaded L-shaped screw arranged radially. Of course, in addition to the portability and tool-free installation characteristics of the L-shaped screw, other screw structures that can be tightened by hand can also be used, such as a T-shaped or enlarged structure at the end of the screw that facilitates hand tightening.

[0035] Further preferably, in this embodiment, the support mechanism 2 includes a crossbeam 25, with support rods 21 detachably connected to both ends of the crossbeam 25 via branch pipes 24 to form an H-shaped support structure. An adjustable-angle base 23 is rotatably mounted on the lower end of the support rod 21, and the upper end of the support rod 21 is connected to a horizontal rod 11 via a connecting bend 22. (See attached specification) Figures 1-2 As shown, the support mechanism 2 is one of the main force-bearing mechanisms used to support the overall weight and limit the tension of the two horizontal bars 11 under the tension from the seat fabric 12. When the seat fabric 12 is subjected to downward stress, such as when a user sits on the seat fabric 12, in order to provide support, the two horizontal bars 11 will inevitably be subjected to a pulling force from the seat fabric 12 towards each other. However, to maintain the relative distance between the two horizontal bars 11 and not affect the user's use, the crossbeam 25 plays a lateral support role. However, this support force is not borne by the crossbeam 25 alone, but works together with the backrest mechanism 3, thereby making the entire seat structure stable. Since the seat fabric 12 is made of a soft structural material, it is used to provide comfort in the sitting posture.

[0036] To balance the convenience of detachment with the stability of the connection, in this embodiment, both ends of the connecting bend 22 are provided with locking screws. The locking structure of the locking screws employs at least one radially arranged locking screw to achieve adjustable connection stability and convenient disassembly by changing the radial stress between the locking screw and the connecting bend 22.

[0037] In this embodiment, the backrest mechanism 3 includes a U-shaped rod 31 detachably connected to a horizontal rod 11 via a connecting bend 22 or a straight sleeve 14. A backrest fabric 32 is slidably connected to the U-shaped rod 31, and a headrest 33 is disposed on the backrest fabric 32 or the U-shaped rod 31. The backrest fabric 32 is slidably sleeved on the straight section of the U-shaped rod 31, and can be disassembled at any time when the seat or recliner structure changes, so as to facilitate the installation of the connecting bend 22 in different positions. The backrest fabric 32 is preferably made of a breathable material with a small degree of elasticity, which facilitates adaptive adjustment of position and improves practicality and ease of adjustment.

[0038] To ensure sufficient comfort for users of different heights in a lying position, please refer to the instruction manual. Figure 3 and Figure 4 As shown, it also includes an extension rod 34 that is connected to the ends of the U-shaped rod 31 and the horizontal rod 11 via a straight sleeve 14 to form a flat reclining bed structure. As another optional feature, a support mechanism 2 can be added to the extension rod 34 to further improve the stability and load-bearing capacity of the reclining chair.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
