Description

Technical Field

[0001] The invention relates to the technical field of outdoor products, in particular to a combined chair. Background Art

[0002] With the rapid development of 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. And modular chairs are necessary equipment for outdoor leisure activities.

[0003] The existing combination chairs have been found to have shortcomings during use. First, a single-point support is used between the armrests of the backrest and the support rods of the chair frame. In order to ensure the smooth realization of the support function, the support point is set relatively high, which makes the armrests of the backrest uncomfortable when used; second, it can only provide the basic function of sitting for the human body, but cannot provide a shaking function, and the backrest cannot be adjusted to different angles.

[0004] In view of this, the inventor hopes to design a combination chair with better use comfort. Summary of the invention

[0005] The purpose of the present invention is to overcome the above problems existing in the traditional technology and provide a combined chair.

[0006] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0007] The present invention provides a combination chair, comprising a backrest and a chair frame, the backrest comprising a backrest body, armrests, armrest support members and a backrest connecting strip, the backrest body being divided into a seat surface area and a backrest area, the backrest body being located on both sides of the seat surface area and being connected with armrests respectively, an armrest support member being installed on the lower side of each armrest near both ends, a backrest connecting strip being installed between the rear end of the armrest and the side of the backrest area adjacent to the backrest body, and the length of the backrest connecting strip being fixed or adjustable; the chair frame comprising a chair frame base and four support rods that can be directly or indirectly connected to the corresponding armrest support members.

[0008] Furthermore, in the above-mentioned combined chair, seat surface supporting members for preventing the seat surface fabric from gathering are respectively installed on both sides of the seat surface area of ​​the backrest body.

[0009] Furthermore, in the above-mentioned combined chair, a seat surface connecting strip is installed between the rear end of the armrest and the rear end of the seat surface area adjacent to the backrest body, and the length of the seat surface connecting strip is fixed or adjustable.

[0010] Furthermore, in the above-mentioned combined chair, an extension piece is installed at the bottom end of the backrest located at all or part of the armrest support pieces.

[0011] Furthermore, in the above-mentioned combination chair, the chair frame base of the chair frame is a folding structure that can be closed and expanded, and specifically includes four single cross rod assemblies respectively located at the front, rear, left and right sides; the bottom ends of two adjacent single cross rod assemblies share a bottom support for providing movable support, and the top ends of two adjacent single cross rod assemblies share a top support for providing movable support.

[0012] Furthermore, in the above-mentioned combined chair, the support rod and the chair frame base are separate structures.

[0013] Furthermore, in the above-mentioned combination chair, the support rod is a fixed-length rod, and the top support is provided with a closed straight sliding groove for facilitating the passage of the fixed-length rod, and the bottom end of the fixed-length rod is hinged to an ear seat fixed on the front or rear single cross rod assembly.

[0014] Furthermore, in the above-mentioned combination chair, the support rod is a telescopic rod with adjustable length, and the telescopic rod includes 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, and the bottom end of the lower section of the telescopic rod is hinged to an ear seat fixed on the front or rear single cross rod assembly.

[0015] Furthermore, in the above-mentioned combination chair, the support rod and the chair frame base are an integrated structure; the support rod is connected to the top end of the single rod in the front or rear single cross rod assembly, and the top support is provided with an open inclined groove or a closed inclined groove for facilitating the support rod to slide along its inner side.

[0016] Furthermore, in the above-mentioned combination chair, the chair frame base of the chair frame is an integral structure or a split structure that cannot be folded, and the support rod and the chair frame base are an integral structure or a split structure.

[0017] The beneficial effects of the present invention are:

[0018] The combined chair of the present invention has a reasonable structural design. On the one hand, double-point support is adopted between the armrests of the backrest and the support rods of the chair frame. On the basis of ensuring the smooth realization of the supporting function, the height of the supporting point can be lowered, so that the height of the armrests is ergonomic, thereby improving the comfort of the armrests when used. On the other hand, in addition to providing the basic function of sitting for the human body, it can also provide a rocking function, and the backrest can be adjusted to different angles, thereby improving the overall comfort of use.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
