Abstract

The utility model provides a folding chair. The folding chair comprises a flexible seat surface, spacer sleeves, side vertical pipes, cross pipes, switching seats, foot seats, horizontal supporting pipes, vertical supporting pipes, end sleeves, seat pipes, armrest pads, fixed seats and inner connecting pipes. The folding chair is characterized in that the fixed seats, the spacer sleeves and the end sleeves are fixedly arranged on the side vertical pipes; the vertical supporting pipes are fixedly arranged on the fixed seats; two ends of the seat pipes are respectively hinged with the side vertical pipes and the vertical supporting pipes by the spacer sleeves; the inner connecting pipes are arranged in the side vertical pipes and the vertical supporting pipes; the foot seats are fixedly arranged at the lower ends of the inner connecting pipes; the horizontal supporting pipes are hinged with the inner connecting pipes; the switching seats are arranged at the two ends of the seat pipes and the horizontal supporting pipes respectively; the cross pipes are fixedly connected with the switching seats; and the flexible seat surface is sleeved on the side vertical pipes and the seat pipes. The folding chair has the beneficial effects that the during seating, when the end sleeves push against the foot seats, four triangular mechanisms formed between the cross pipes and the side vertical pipes, the vertical supporting pipes as well as the inner connecting pipes achieve a self-locking state and provide forces for supporting the flexible seat surface; 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

Folding seat

Technical field

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

Background technology

Chinese patent database discloses the utility model of denomination of invention for " a kind of rest folding chair frame " on August 25th, 2004, and the patent No. is 03217983.9.A kind of rest folding chair frame comprises two forelegs, two back leg component parts, and rear leg assemblies is that telescopic tube assembly comprises sleeve and loop bar, the hinged connection of the upper end of loop bar and foreleg; Two cross bars, the hinged connection of cross bar and foreleg, the hinged connection of rear end and sleeve; Two handrails, handrail middle part and the foreleg hinged connection in middle part, rear end and the sleeve hinged connection in middle part; The first cross members, it comprises two support bars of decussate, the two ends of support bar respectively with the hinged connection in lower end of front end and the foreleg of cross bar; The second cross members, it comprises two support bars of decussate, the two ends of support bar respectively with the upper end of foreleg and the hinged connection in upper end of sleeve.The shortcoming of this folding seat is that two cross bars and the two foreleg assemblies that support seat surface are realized cross-brace by the first cross members and the second cross members of being arranged to X-shaped, when seat surface is received when taking a seat power, the first cross members and the second cross members that support two cross bars and two foreleg groups can rotate, cause seat surface to stay, that takes a seat is comfortable bad, and simultaneously the structure member of folding seat is many, and assembles and expend man-hour, cause cost compare high, be unfavorable for promoting.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 the folding seat of the flexible seat surface of a kind of cross-brace.

The technical scheme that the utility model adopts is: a kind of folding seat, and it comprises flexible seat surface, spacer sleeve, edge-on pipe, cross pipe, adapter, runners, stull pipe, perpendicular stay tube, end cover, seat pipe, armrest pad, holder, inner connecting tube; It is characterized in that setting firmly on two edge-on pipes that be arranged in parallel holder, spacer sleeve and end cover; One end of two perpendicular stay tubes that be arranged in parallel is installed on the holder, and the other end is provided with the end cover, and the middle part of perpendicular stay tube sets firmly spacer sleeve; The two ends of two seat pipes that be arranged in parallel are hinged by spacer sleeve and edge-on pipe, perpendicular stay tube respectively; Respectively be provided with an inner connecting tube in edge-on pipe and the perpendicular stay tube, the lower end of inner connecting tube sets firmly runners; The stull pipe connects with inner connecting tube phase dumpling; The two ends of seat pipe respectively are provided with adapter, and the two ends of stull pipe respectively are provided with adapter; Adapter Joint on two cross pipes upper ends that be arranged in parallel and the seat pipe, the adapter Joint on lower end and the stull pipe; The flexible mount surface cover is connected on edge-on pipe and the seat pipe.

Described edge-on pipe is provided with perpendicular pin pipe, handrail tube, the penstock that connects by arc transition, installs inner connecting tube in the set perpendicular pin pipe; Set handrail tube is provided with armrest pad, is used for shelving arm; Described penstock is provided with flexible seat surface, relies on for backrest.

Form rigid frame between described edge-on pipe, perpendicular stay tube, the seat pipe.

Form U-shaped framework between described stull pipe and the inner connecting tube, the stull pipe can guarantee that inner connecting tube is in perpendicular pin pipe and perpendicular stay tube inter-sync slippage.

Described cross pipe and flexible seat surface have formed four symmetrically arranged variable triangle mechanisms between cross pipe and the ground.

Four symmetrically arranged variable triangle mechanisms have been formed between described cross pipe and edge-on pipe, perpendicular stay tube, the inner connecting tube, when end overlaps with runners inconsistent, make this triangle mechanism be issued to self-locking state at the state of the power of taking a seat, the support force to flexible seat surface is provided.

The beneficial effects of the utility model are: by forming two rigid frames by edge-on pipe, perpendicular stay tube, seat pipe, inner connecting tube and stull pipe, linked together by cross pipe between the framework, during use, under the effect of the power of taking a seat, the end cover is inconsistent with runners, reach self-locking state by having formed four symmetrically arranged variable triangle mechanisms between cross pipe and edge-on pipe, perpendicular stay tube, the inner connecting tube, the support force to flexible seat surface is provided; When folding, slippage by inner connecting tube makes cross pipe and edge-on pipe, erects the triangle mechanism generation counter motion that has formed two symmetries between stay tube, the inner connecting tube, until two frameworks are bonded to each other, realize folding, therefore, the utlity model has simple in structure, easy to operate and be suitable as indoor, garden, camp, characteristics that the occasion such as sandy beach is used.
