Abstract

The utility model provides a folding chair. The folding chair comprises a flexible back, a seat pipe, a rear leg pipe, nuts, linkage pipes, seat supporting pipes, limiting seats, a flexible seat surface and a front leg pipe and is characterized in that the rear leg pipe and the seat pipe are hinged on the front leg pipe; the limiting seats are arranged at the ports of the rear leg pipe; the rear leg pipe and the seat pipe are hinged by the linkage pipes; the nuts are arranged at the ports of the linkage pipes; the flexible back is sleeved at the upper end of the front leg pipe; the flexible seat surface is sleeved at the front end of the seat pipe; and the front leg pipe, the rear leg pipe, the linkage pipes and the seat pipe form a four-bar motion mechanism. The folding chair has the advantages that after the chair is unfolded, the limiting seats push against the seat pipe, so that a triangular supporting structure is formed by the seat pipe, the front leg pipe and the rear leg pipe, thus keeping the four-bar mechanisms in a static supporting state after seating; and therefore the folding chair has a simple structure, is convenient to operate and is suitable to use in rooms, courtyards, camps and the like.

Description

A kind of folding seat

Technical field

The utility model relates to a kind of chair, particularly a kind of folding seat.

Background technology

The outdoor chair that the family expenses chair of commonly using at present or garden are used adopts reassembling type or one Welding Structure to be made usually, the chair of reassembling type need to carry out loaded down with trivial details assembling when using, power when relatively expending, particularly when collection, have and to dismantle the smaller volume that just can make chair, and the dismounting back part is more scattered, also is not easy to preserve; Although the welded chair of one does not need dismounting before use, the monomer volume ratio of chair is larger, need to take larger space during collection.For this point shortcoming, be necessary to make improvements.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of folding seat that does not need dismounting.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of folding seat, and it comprises the flexible back side, seat tubes, rear foot tube, nut, linkage tube, seat stay pipe, limit base, flexible seat surface, front foot pipe; It is characterized in that hinged rear foot tube and seat tubes on the front foot pipe, be provided with limit base at the port of rear foot tube; Be hinged by linkage tube between rear foot tube and the seat tubes, be provided with nut at the port of linkage tube; The flexible back side is socketed in the upper end of front foot pipe, and the flexible mount surface cover is connected on the front end of seat tubes.

The forward of described front foot pipe is set to the U-shaped pipe, the support that lands of the bottom of U-shaped pipe, and the openend of U-shaped pipe is socketed the flexible back side, as relying on supporting surface; The laterally disposed of front foot pipe is S shape, guarantees that landing of front foot pipe forms seat depth between support and the backrest dependence.

The forward of described rear foot tube is set to the U-shaped pipe, the support that lands of the bottom of U-shaped pipe, and the port of U-shaped pipe sets firmly limit base and is hinged with front foot pipe; The laterally disposed of rear foot tube is L shaped, makes spacing between front foot pipe and the rear foot tube can guarantee the stability of chair.

Four bar linkage motion mechanisms have been formed between described front foot pipe, rear foot tube, linkage tube, the seat tubes, after chair launches, limit base and seat tubes are inconsistent, make between seat tubes, front foot pipe, the rear foot tube to have formed triangular support structure, make the rear quadric chain of taking a seat keep the stationary support state.

The utility model has the advantages that: by hinged rear foot tube and seat tubes on the front foot pipe, be provided with limit base at the port of rear foot tube; Be hinged by linkage tube between rear foot tube and the seat tubes, be provided with nut at the port of linkage tube; The flexible back side is socketed in the upper end of front foot pipe, and the flexible mount surface cover is connected on the front end of seat tubes; Four bar linkage motion mechanisms have been formed between front foot pipe, rear foot tube, linkage tube, the seat tubes, after chair launches, limit base and seat tubes are inconsistent, make between seat tubes, front foot pipe, the rear foot tube and formed triangular support structure, make the rear quadric chain of taking a seat keep the stationary support state, therefore the utlity model has simple in structurely, easy to operate, be fit to the sandy beach, camp, the characteristics such as various occasion uses such as garden.

The specific embodiment

Below by specific embodiment, and by reference to the accompanying drawings the technical solution of the utility model is described further.

Embodiment: with reference to Fig. 1, a kind of folding seat, it comprises the flexible back side 1, seat tubes 2, rear foot tube 3, nut 4, linkage tube 5, seat stay pipe 6, limit base 7, flexible seat surface 8, front foot pipe 9; It is characterized in that hinged rear foot tube 3 and seat tubes 2 on the front foot pipe 9, be provided with limit base 7 at the port of rear foot tube 3; Be hinged by linkage tube 5 between rear foot tube 3 and the seat tubes 2, be provided with nut 4 at the port of linkage tube 5; The flexible back side 1 is socketed in the upper end of front foot pipe 9, and flexible seat surface 8 is socketed in the front end of seat tubes 2.

With reference to Fig. 2, during use, by having formed four bar linkage motion mechanisms between front foot pipe 9, rear foot tube 3, linkage tube 5, the seat tubes 2, promote the motion of four connecting rods, after seat tubes 2 and limit base 7 are inconsistent, the rigid triangle supporting construction that has formed self-locking state between seat tubes 2, front foot pipe 9, the rear foot tube 3, angle between seat tubes 2, front foot pipe 9, the rear foot tube 3 is remained unchanged under the power of taking a seat, thereby cause quadric chain to reach the stationary support state, at this moment, chair is in the use state after launching.

With reference to Fig. 3, when folding, only need upwards lift seat tubes 2, seat tubes 2 and limit base 7 are separated, at this moment, remove self-locking by having formed the rigid triangle supporting construction between seat tubes 2, front foot pipe 9, the rear foot tube 3, make by having formed four bar linkage motion mechanisms between front foot pipe 9, rear foot tube 3, linkage tube 5, the seat tubes 2 to move, at this moment, chair is in the folded state.

With reference to Fig. 4, when continuing to fold, continue upwards to lift seat tubes 2, continue to promote to move by having formed four bar linkage motion mechanisms between front foot pipe 9, rear foot tube 3, linkage tube 5, the seat tubes 2, until seat tubes 2 and the flexible back side 1 are inconsistent, at this moment, reach the state after folding, the smaller volume of chair is convenient for carrying and transports.

Above-described embodiment is a kind of preferred version of the present utility model, is not the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
