Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of furniture, in particular to a novel folding chair with a steel-wood structure. Background Art
[0002] In modern society, folding seats have become one of the furniture widely used in various occasions, such as outdoor terraces, restaurants, event venues, etc. The traditional folding seat design is mainly based on a folding frame and a seat surface, and some of them come with a foldable backrest. Although these traditional folding seats have certain advantages in providing convenience and easy storage, they often have some inconveniences and defects, which limit their practical application and usage experience.
[0003] The components of traditional folding chairs are large in size and may require a lot of strength to fold and unfold, which may cause trouble for some special groups, such as the elderly or people with physical disabilities. Secondly, the structure of traditional folding chairs often concentrates the force points on a single part at the hinge, which is prone to loosening or breaking during folding after long-term use.
[0004] Therefore, in view of the above-mentioned problems and limitations of traditional folding seats, an innovative design is urgently needed to provide a more convenient, stable and easy-to-store folding chair, so it is necessary to design corresponding technical solutions to solve the existing technical problems.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-3 The embodiment of the utility model provides a technical solution: a foldable portable seat, comprising two bracket assemblies, the bracket assemblies comprising a front support rod 1, an oblique support rod 2 and a rear support rod 3, the top of the oblique support rod 2 is rotatably connected to the top of the rear support rod 3, and the bottom of the oblique support rod 2 is rotatably connected to the bottom of the front support rod 1, a cross bar 1 4 is arranged between the top inner walls of the two rear support rods 3, a rotatable seat plate 7 is arranged on the cross bar 1 4, a cross bar 2 5 is arranged between the top outer walls of the two front support rods 1, the cross bar 2 5 is fixedly connected to the front support rod 1, a cross bar 3 6 is arranged between the inner walls of the bottoms of the two rear support rods 3, the cross bar 3 6 is fixedly connected to the rear support rod 3, and pull ropes 8 are symmetrically arranged on both sides of the cross bar 2 5, and the bottom ends of the pull ropes 8 are connected to the cross bar 3 6.
[0022] The seat plate 7 is made of a hard material, and a hook strip is provided at the front end of the seat plate 7, which can be buckled with the cross bar 2 5. The hard seat plate 7 is used to enhance the supporting effect, and the hook strip can be buckled with the cross bar 2 5 to enhance the stabilizing effect.
[0023] The seat plate 7 is provided with a plurality of air holes 9, which can be used to reduce the weight and also to provide ventilation.
