Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 6, a folding chair with independent armrest members comprises a folding chair frame, a group of side standing mechanisms arranged in parallel, a front cross mechanism 1 and a rear cross mechanism 2 positioned between the side standing mechanisms.

The side-standing mechanism comprises a backrest pipe 31, a rear foot pipe 32, a seat pipe 33 and a supporting pipe, wherein the backrest pipe 31 is provided with an articulated seat 4, and the upper end of the rear foot pipe 32 is articulated with the articulated seat 4. The rear end of the seat tube 33 is connected with the rear leg tube 32, and the middle part is hinged with the backrest tube 31. The front part of the seat tube 33 is fixedly connected with a front support connecting piece 5, the upper end of the support tube is hinged with the front support connecting piece 5, and the lower end of the support tube is hinged with the backrest tube 31.

As shown in fig. 2 and 3, the backrest tube 31 is hinged to the armrest via a connecting member, the connecting member includes two iron sheets disposed on two sides of the backrest tube 31, the iron sheets are substantially triangular, two ends of the iron sheets are respectively a first end and a second end, the first end is hinged to the backrest tube 31, and the second end is hinged to the armrest and the limiting column 62. The cross section of the limiting column 62 is of a polygonal structure, two surfaces of the limiting column 62 are a first limiting surface and a second limiting surface respectively, the first limiting surface of the limiting column 62 abuts against the backrest tube 31 when the armrest piece is unfolded, and the second limiting surface of the limiting column 62 abuts against the backrest tube 31 when the armrest piece is folded, so that the armrest piece is prevented from overturning.

The scheme solves the problem that in the prior art, the hard armrest 72 folding chair is fixed by the armrest 72 after being unfolded and can not be independently folded or unfolded according to needs. The connecting piece is arranged at the connecting part of the backrest tube 31 and the handrail piece, so that the handrail piece is not limited by the linkage of the folding chair frame, and the folding chair is more flexible to use.

In this embodiment, the armrest member includes a supporting member 71 and an armrest 72, the supporting member 71 is fixedly connected to an iron plate located outside the backrest pipe 31, and the armrest 72 is fixedly connected above the supporting member 71. In order to ensure the supporting strength of the supporting member 71, the supporting member 71 is made of iron, plastic or other rigid materials. The armrest 72 is made of iron, wood, plastic or other materials, or made of a combination of two or more materials.

In the embodiment shown in fig. 4, a sliding member 81 is sleeved on the rear leg tube 32, and the rear end of the seat tube 33 is hinged to the sliding member 81. When folding, the sliding member 81 drives the rear end of the seat tube 33 to move downward, so that the seat tube 33 is folded upward. The rear leg tube 32 is fixedly connected with a limiting member 82 for limiting the displacement of the sliding member 81 and preventing the rear end of the rear seat tube 33 from moving upwards to cause instability when the folding seat frame is unfolded.

In the embodiment shown in fig. 5, the support tube is a telescopic tube, and includes an inner tube 341, an outer tube 342, and a stop sleeve 343 disposed at the connection between the inner tube 341 and the outer tube 342, the upper end of the outer tube 342 is hinged to the front support connector 5, and the lower end of the inner tube 341 is hinged to the backrest tube 31. When the folding chair frame is folded, the front end of the seat tube 33 moves upwards to drive the outer tube 342 to extend upwards, so that the seat tube 33 can be smoothly folded, and the limiting sleeve 343 is used for preventing the inner tube 341 from coming out when the outer tube 342 extends out to reach the limit value.

The front cross mechanism 1 comprises two straight pipes hinged to each other in the middle, the upper ends of the straight pipes are hinged to the front support connecting pieces 5 on the same side, and the lower ends of the straight pipes are hinged to the inner pipes 341 on the same side.

The rear cross mechanism 2 comprises two straight pipes hinged with each other at the middle part, and two ends of the straight pipes are respectively hinged with the backrest pipes 31 at the same side.

In order to further ensure the stability of the folding chair frame when being unfolded for use, the lower ends of the backrest tube 31 and the rear foot tube 32 are sleeved with the foot sleeves 9.

In addition, the folding chair can be spliced into a double-person bench or a multi-person bench under the connection of the temporary assembly parts, so that the experience feeling in the use process is improved.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
