Abstract

The utility model relates to a double folding chair. The double folding chair comprises a flexible seat face, at least three groups of side frames, switchover seats and at least four groups of cross tubes. The double folding chair is characterized in that the at least three groups of side frames are upright, and the flexible seat face is sleeved on the side frames; the switchover seats are arranged at the four ends of each group of cross tubes and are sleeved on the side frames; and every two adjacent groups of side frames are connected together through two groups of cross tubes. Two single folding chairs are combined into one double folding chair through sharing one group of side frames; during use, end sleeves abut against foot seats, and a self-locking state is realized by variable triangular mechanisms formed by the cross tubes, side upright tubes, vertical supporting tubes and internal connecting tubes, thereby supplying a supporting force to the flexible seat face; and when the double folding chair is folded up, through the slippage of the internal connecting tubes, the triangular mechanisms formed by the cross tubes, the side upright tubes, the vertical supporting tubes and the internal connecting tubes do reverse movement until all the side frames get together, thereby realizing folding. Thus, the double folding chair is simple in structure and convenient to operate and can be used indoors and in courtyards, camps and the like.

Description

A kind of double folding chair

Technical field

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

Background technology

At present, common folding seat is mostly single folding seat, when many occasions out of doors need two people to sit together chat, often need to carry two single folding seat, yet, the materials of two single folding seat are more than double folding chair materials, Heavy Weight, this tends to increase the burden of going out, and also is unfavorable for energy-conserving and environment-protective, therefore, be necessary to design a kind of double folding chair and satisfy this class demand.

Summary of the invention

The purpose of this utility model is to provide a kind of double folding chair.

The technical scheme that the utility model adopts is: a kind of double folding chair, and it comprises flexible seat surface, body side frame, adapter, cross pipe; It is characterized in that being provided with at least three groups of upright body side frames, flexible seat is socketed on body side frame; At least be provided with four groups of cross pipes, four ends of every group of cross pipe are provided with adapter, and adapter is socketed on body side frame; Link together by two groups of cross pipes between the body side frame of every two groups of vicinities.

Described body side frame is provided with holder, edge-on pipe, Connection Block, seat pipe, perpendicular stay tube, end cover, runners, stull pipe, inner connecting tube; It is characterized in that edge-on pipe and perpendicular stay tube by the holder Joint, the lower end of edge-on pipe and perpendicular stay tube sets firmly respectively the end cover; The two ends of seat pipe set firmly respectively Connection Block, and Connection Block is installed in respectively on edge-on pipe and perpendicular stay tube; The two ends of stull pipe set firmly respectively runners, set firmly inner connecting tube on runners; Inner connecting tube is socketed in respectively on edge-on pipe and perpendicular stay tube; Flexible seat surface is socketed in respectively on edge-on pipe and seat pipe, on the present pipe of adapter socket.

Described inner connecting tube can be in perpendicular pin pipe and perpendicular stay tube inter-sync slippage.

Formed variable triangle mechanism between described cross pipe and edge-on pipe, perpendicular stay tube, inner connecting tube, inconsistent with runners when the end cover, 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 sharing one group of side frame pipe, two single folding seat are combined into a double folding chair, during use, under the effect of the power of taking a seat, the end cover is inconsistent with runners, reach self-locking state by the variable triangle mechanism that forms between cross pipe and edge-on pipe, perpendicular stay tube, 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 forms between stay tube, inner connecting tube, until every group of body side frame is 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.

Fig. 2 is the schematic perspective view after the utility model folds.

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, Fig. 2, a kind of double folding chair, it comprises flexible seat surface 1, body side frame 2, adapter 3, cross pipe 4; It is characterized in that being provided with at least three groups of upright body side frames 2, flexible seat 1 is socketed on body side frame 2; At least be provided with four groups of cross pipes 4, four ends of every group of cross pipe 4 are provided with adapter 3, and adapter 3 is socketed on body side frame 2; Link together by two groups of cross pipes 4 between the body side frame 2 of every two groups of vicinities.Described body side frame is provided with holder 21, edge-on pipe 22, Connection Block 23, seat pipe 24, perpendicular stay tube 25, end cover 26, runners 27, stull pipe 28, inner connecting tube 29; It is characterized in that edge-on pipe 22 and perpendicular stay tube 25 by holder 21 Joints, the lower end of edge-on pipe 22 and perpendicular stay tube 25 sets firmly respectively end cover 26; The two ends of seat pipe 24 set firmly respectively Connection Block 23, and Connection Block 23 is installed in respectively on edge-on pipe 22 and perpendicular stay tube 25; The two ends of stull pipe 28 set firmly respectively runners 27, set firmly inner connecting tube 29 on runners 27; Inner connecting tube 20 is socketed in respectively on edge-on pipe 22 and perpendicular stay tube 25.During use, under the effect of the power of taking a seat, end cover 26 is inconsistent with runners 27, reach self-locking state by having formed variable triangle mechanism between cross pipe 4 and edge-on pipe 22, perpendicular stay tube 25, inner connecting tube 29, support force to flexible seat surface 1 is provided, at this moment, is in the use state after the chair exhibition.

With reference to Fig. 2, when folding, upwards lift outermost two groups of body side frames 2, and outermost two body side frames 2 are drawn close to the center, at this moment, inner connecting tube 29 skids off in perpendicular stay tube 25 and edge-on pipe 22, makes the distance between seat pipe 24 and stull pipe 28 elongated, cross pipe 4 rotates, until every group of side frame pipe 2 abuts against together, at this moment, chair is folded into flat, smaller volume is convenient for carrying.

Above-described embodiment is a kind of preferred version of the present utility model, is not 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.
