Description

Technical Field

[0001] This utility model relates to the field of outdoor products technology, and in particular to a combination chair. Background Technology

[0002] With rapid economic and social development, people have increasingly higher demands for quality of life, and outdoor leisure activities such as self-driving tours are becoming more and more popular. And modular chairs are essential equipment for outdoor leisure activities.

[0003] Existing modular chairs have several shortcomings. First, the armrests on the backrest and the support rods of the chair frame use a single-point support. To ensure the smooth implementation of the support function, the support point is set too high, resulting in discomfort when using the backrest and armrests. Second, they can only provide the basic function of sitting and cannot provide a rocking function, and the backrest cannot be adjusted to different angles.

[0004] In view of this, the inventors hoped to design a combination chair with better comfort. Summary of the Invention

[0005] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a modular chair.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0007] This utility model provides a combination chair, including a backrest and a chair frame. The backrest includes a backrest body, armrests, armrest supports, and a backrest connecting strip. The backrest body is divided into a seat area and a backrest area. Armrests are connected to both sides of the seat area of ​​the backrest body. An armrest support is installed on the lower side of each armrest near both ends. A backrest connecting strip is installed between the rear end of the armrest and the side of the backrest area adjacent to the backrest body. The length of the backrest connecting strip is fixed or adjustable. The chair frame includes a chair frame base and four support rods that can be directly or indirectly connected to the corresponding armrest supports.

[0008] Furthermore, in the aforementioned combination chair, the backrest body is equipped with seat support components on both sides of the seat surface area to prevent the seat surface fabric from gathering.

[0009] Furthermore, in the aforementioned combination 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 aforementioned combination chair, the backrest is equipped with an extension at the bottom end of all or part of the armrest support.

[0011] Furthermore, in the aforementioned combination chair, the chair frame base is a folding structure that can be closed and extended, specifically comprising four single crossbar assemblies located on the front, rear, left, and right sides respectively; the bottom ends of two adjacent single crossbar assemblies share a bottom support for providing movable support, and the top ends of two adjacent single crossbar assemblies share a top support for providing movable support.

[0012] Furthermore, in the aforementioned combination chair, the support rod and the chair frame base are separate structures.

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

[0014] Furthermore, in the aforementioned combination chair, the support rod is a telescopic rod with adjustable length. 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 a single crossbar assembly on the front or rear side.

[0015] Furthermore, in the aforementioned combination chair, the support rod and the chair frame base are an integral structure; the top of the support rod is connected to the top of the single rod in the front or rear single cross rod assembly, and the top support is provided with an open or closed oblique groove that facilitates the sliding of the support rod along its inner side.

[0016] Furthermore, in the aforementioned combination chair, the chair frame base is a non-foldable one-piece structure or a separate structure, and the support rod and the chair frame base are either one-piece structures or separate structures.

[0017] The beneficial effects of this utility model are:

[0018] This utility model of a combination chair has a reasonable structural design. On the one hand, the armrests of the backrest and the support rods of the chair frame adopt a double-point support. While ensuring the smooth realization of the support function, the height of the support point can be reduced, thereby making the armrest height conform to ergonomics and improving the comfort of using the armrests. On the other hand, in addition to providing the basic function of sitting, it can also provide a rocking function based on the connection method between the backrest and the chair frame. At the same time, the backrest can be adjusted to different angles, improving the overall comfort of use.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description
