This application claims priority to CN. Patent Application No. 202411615726.6, filed on November 13, 2024, which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present invention relates to the technical field of outdoor products, and in particular to a combined chair.

BACKGROUND

With the rapid development of the economy and society, people have higher and higher requirements for the quality of life, and outdoor leisure activities such as self-driving tours are becoming more and more popular. The combined chairs are necessary equipment for outdoor leisure activities.

Existing combined chairs are found to have shortcomings during use. First, a single-point support is adopted between the armrests of the backrest and the support rods of the chair frame; and the support points are set higher to ensure that the support function is implemented successfully, leading to discomfort when using the armrests of the backrest. Second, the existing combined chairs can only provide the basic function of human sitting, but cannot provide a rocking function. At the same time, the backrests thereof cannot be adjusted at different angles.

In view of this, the inventor expects to design a combined chair that offers greater comfort of use.

SUMMARY

The present invention aims to overcome the above problems existing in traditional technology and to provide a combined chair.

To implement the above technical objectives and achieve the above technical effects, the present invention is implemented through the following technical solutions:

The present invention provides a combined chair, comprising a backrest and a chair frame, wherein the backrest comprises a backrest body, armrests, armrest support members, and backrest connecting strips, the backrest body is divided into a seat area and a backrest area, the armrests are respectively connected to two sides of the backrest body that are located at the seat area, the armrest support members are mounted at a lower side of each armrest at positions close to two ends, the backrest connecting strips are mounted between rear ends of the armrests and side portions of the backrest area adjacent to the backrest body, and lengths of the backrest connecting strips are fixed or adjustable; and the chair frame comprises a chair frame foundation and four support rods that can be directly or indirectly connected to the corresponding armrest support members.

Further, in the above combined chair, seat fabric support members that prevent fabric of the seat area from gathering are respectively mounted on the two sides of the backrest body that are located at the seat area.

Further, in the above combined chair, seat connecting strips are mounted between the rear ends of the armrests and rear ends of the seat area adjacent to the backrest body, and lengths of the seat connecting strips are fixed or adjustable.

Further, in the above combined chair, extension members are additionally mounted on the backrest at bottom ends of all or part of the armrest support members.

Further, in the above combined chair, the chair frame foundation of the chair frame is of a folded structure that can be folded and unfolded, which specifically comprises four single cross rod assemblies respectively located on a front side, a rear side, a left side, and a right side; and bottom ends of two adjacent single cross rod assemblies share one bottom support base for providing movable supporting, and top ends of the two adjacent single cross rod assemblies share one top support base for providing movable supporting.

Further, in the above combined chair, the support rods and the chair frame foundation are of a split structure.

Further, in the above combined chair, the support rods are fixed-length rods with fixed lengths, the top support base is internally provided with a closed straight sliding groove for facilitating passing of the fixed-length rod, and a bottom end of the fixed-length rod is hinged to a lug base fixed to the single cross rod assembly on the front side or the rear side.

Further, in the above combined chair, the support rods are telescopic rods with adjustable lengths, the telescopic rod comprises an upper section and a lower section that can slide relative to each other, the upper section of the telescopic rod is hinged to the top support base, and a bottom end of the lower section of the telescopic rod is hinged to a lug base fixed to the single cross rod assembly on the front side or the rear side.

Further, in the above combined chair, the support rods and the chair frame foundation are of an integral structure; and the support rod is integrally connected to a top end of a single rod in the single cross rod assembly on the front side or the rear side, and the top support base is internally provided with an open inclined sliding groove or a closed inclined sliding groove for facilitating inner-side sliding of the support rod along an inner side of the top support base.

Further, in the above combined chair, the chair frame foundation of the chair frame is of an integral structure or a split structure that cannot be folded, and the support rods and the chair frame foundation are of an integral structure or a split structure.

The present invention has the following beneficial effects:

The combined chair of the present invention has a reasonable structural design. On the one hand, a double-point support is adopted between the armrests of the backrest and the support rods of the chair frame, which can reduce setting heights of support points on the basis of ensuring that a support function is implemented successfully, thereby enabling heights of the armrests to be ergonomic and improving comfort when using the armrests. On the other hand, in addition to providing a basic function of human sitting, the combined chair can also provide a rocking function, and at the same time, the backrest can be adjusted at different angles, improving the overall comfort of use.

Certainly, any product implementing the present invention does not necessarily need to simultaneously achieve all of the above advantages.
