Description
Technical Field
[0001] The utility model relates to the technical field of chairs, and specifically relates to a gathering chair. Background Art
[0002] Gathering chairs are favored by people because of their characteristics of being freely retractable. When needed, they can be unfolded for sitting, and when not needed, they can be folded up, without wasting space and with strong portability. There are many types of gathering chairs on the market at present, and most of them are composed of a metal chair frame and an Oxford cloth chair surface. The chair frame usually includes two leg frames on the left and right. The front ends of the two leg frames are connected by a front folding frame, and the rear ends of the two leg frames are respectively connected to two back frames; a rear folding frame is arranged between the two back frames. The rear folding frame is composed of a parallel four-bar parallel mechanism, including an upper link assembly, a lower link assembly and a connecting rod. The two ends of the upper link assembly are connected to the back frame, the two ends of the lower link assembly are connected to the leg frame, and the middle parts of the upper link assembly and the lower link assembly are connected by a connecting rod; when in use, the folding or unfolding of the chair frame in the left-right direction is realized by the up-and-down movement of the connecting rod.
[0003] Since the lower link assembly of the rear folding frame is connected to the leg frame, and the width between the two leg frames is different from the width between the two back frames, this results in different sizes of the upper link assembly and the lower link assembly, and two sets of molds need to be opened during processing, with a complex structure and high cost. In addition, only the upper link assembly of the chair back plays a supporting role, and the comfort is also poor. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the above defects of the prior art and provide a gathering chair with a simple structure, low cost, and a more comfortable backrest when in use.
[0005] The technical solution of the utility model is to provide a gathering chair with the following structure: including a gathering chair frame and a chair surface detachably connected to the gathering chair frame. The gathering chair frame includes leg frames, a front folding frame, back frames and a rear folding frame; there are two leg frames spaced left and right. The two ends of the front folding frame are respectively hinged to the front ends of one of the leg frames, and the front folding frame can be folded up to make the front ends of the two leg frames approach each other. There are two back frames, which are respectively hinged to the rear ends of one of the leg frames. The rear folding frame is connected between the two back frames, and the rear folding frame can be folded up to make the rear ends of the two leg frames approach each other; the rear folding frame includes two support components and a connecting rod. The two support components are arranged at intervals up and down; each support component includes a first support rod, a second support rod and a hinge. The opposite ends of the first support rod and the second support rod are hinged to the hinge, and the opposite ends are hinged to the corresponding back frame; the two ends of the connecting rod are respectively connected to one of the hinges for forcing the two hinges to move synchronously.
[0006] After adopting the above structure, compared with the prior art, the gathering chair in the present utility model has the following advantages:
[0007] Both support components of the rear folding frame are connected to the backrest frame, which can make the backrest more comfortable while ensuring the stability of the seat; since both support components are connected to the backrest frame, the two hinge joints can be made the same, which reduces the cost of the mold and is also more convenient for assembly.
[0008] Preferably, a through groove penetrating the left and right end faces thereof is provided on the hinge joint, and the opening of the through groove is arranged downward; the opposite ends of the first support rod and the second support rod are hinged in the through groove; when the gathering chair frame is unfolded for use, the height of the support component gradually decreases from both ends to the middle.
[0009] After such a setting, when a user sits on the chair, a backward and downward force will be exerted on the support component. Since the top wall in the through groove abuts against the upper end faces of the first support rod and the second support rod, it can play a good supporting role to prevent the gathering chair from automatically folding up, making the gathering chair more stable during use; when it is necessary to fold up the gathering chair, only need to lift the connecting rod, and make the support component change from concave to horizontal and then to convex upward, then the gathering chair can be folded up.
[0010] Preferably, a connecting hole penetrating the upper and lower ends thereof is provided in the middle of the hinge joint for connecting the connecting rod.
[0011] Preferably, the leg frame includes a front leg, a rear leg, a cross bar and an armrest. The upper ends of the front leg and the rear leg are both hinged to the armrest, and the middle parts of the front leg and the rear leg are both hinged to the cross bar.
[0012] Preferably, the front folding frame includes two front support rods hinged in an X shape, and the two ends of the front support rod are respectively hinged to the corresponding front leg and the cross bar.
[0013] Preferably, the backrest frame includes a back rod, the lower end of the back rod is hinged to the rear leg, and the middle part of the back rod is hinged to the armrest.
[0014] Preferably, the chair surface includes a back surface and a seat surface made of a flexible material, and the back surface and the seat surface are integrally formed. This can reduce the processing and assembly processes of the chair surface, which is simple and convenient. Description of the Drawings
