Abstract

The utility model provides a bamboo backed armchair comprising four supporting feet with U-shaped structures, a sitting surface interlaced vertically and horizontally, handrails, a backrest and a chair ring, wherein the sitting surface is arranged on support parts at the upper ends of the supporting feet; foot parts at the lower ends of two adjacent supporting feet are in glue joint; the lower ends of the handrails are in glue joint with the foot parts at the lower ends of the supporting feet; two sides of the backrest are respectively in glue joint with the rear sides of the handrails on the left and right sides of the sitting surface; the lower surface of the chair ring is in glue joint with the handrails and the backrest; and the lower tail ends of the handrails, the backrest and the chair ring are aligned with the tail ends of the foot parts of the supporting feet. The whole components of the bamboo backed armchair adopt bamboo structures; bamboo is subjected to hot bending processing to form the supporting feet, the handrails, the backrest and the chair ring, so that not only can the characteristics of spreading, vertical stress, easiness in hot bending processing of the bamboo be fully utilized, but also the structural strength requirement of the chair is met while the structure of the chair is simplified; and the bamboo backed armchair is a bamboo ancient folding chair which is ingenious in design, can produced in a large scale, is concise and stable in structure, and conform to the aesthetic needs of the public.

Description

A kind of bamboo round-backed armchair

Technical field

The utility model is a kind of furniture, is specifically related to a kind of bamboo round-backed armchair, belongs to the innovative technology of existing bamboo furniture.

Background technology

Bamboo wood is as localized fast growing wood, and in recent years research and development both domestic and external are more, particularly in the base material research and development application of recombining bamboo.At furniture industry, bamboo wood is also by extensive base material as furniture, for the manufacture of furniture such as sofa, chairs.

Bamboo chair is as daily furniture, and its intensity must satisfy instructions for use, but traditional bamboo chair satisfies instructions for use in order to guarantee its intensity, and complete bamboo material is all adopted in its force part, and strap-on structure is used in the junction.After recombining bamboo occurred, bamboo also adopted Tenon to connect, but Recombined bamboo furniture is consistent with the solid wood furniture structure, substantially be in bamboo imitation timber state, fail to show completely the bamboo wood characteristics, cause existing bamboo round-backed armchair integral body heavier, cost is high, and elasticity is also bad, also has the overall structure of chair also complicated.

Summary of the invention

The purpose of this utility model be to provide a kind of show completely bamboo U.S., simple for structure stable, cost is low, bamboo round-backed armchair that can large-scale production.The utility model is reasonable in design, and is convenient and practical.

In order to achieve the above object, the technical solution of the utility model is: a kind of bamboo round-backed armchair, comprise bracing frame, be installed in the seat face on the bracing frame, the both sides of sitting face are provided with handrail, the rear side of seat face is provided with backrest, support frame as described above comprises the feet that is located at respectively below around the seat face, and feet is U-shaped structure, and the seat face is installed in the support portion of feet upper end, the foot of adjacent two feet lower ends interconnects, and foot's end of all feets at grade.

The lower end of above-mentioned handrail is adjacent to the foot of feet lower end and is connected, and the upper end of handrail exceeds the upper surface of seat face.

The both sides of above-mentioned backrest are adjacent to the rear side of the handrail of sitting the face left and right sides respectively and are connected.

The chair circle also is installed on the above-mentioned handrail, and the lower surface of chair circle is connected with backrest with handrail and is connected.

Above-mentioned feet, handrail, backrest and chair circle junction is each other adopted splicing or is threaded.

Above-mentioned handrail, backrest and the terminal of chair circle below all align with foot's end of feet.

The support portion of above-mentioned feet offers installing hole, and the seat face is fixed on the installing hole of support portion.

Above-mentioned seat face is to interweave in length and breadth and consist of by knitting bar, and the installing hole of support portion is passed respectively at the two ends of knitting bar.

The cross section of above-mentioned feet, handrail, backrest and chair circle is rectangle.

The shape of cross section of above-mentioned feet, handrail, backrest and chair circle or size are identical.

Whole member of the present utility model adopts the structure of bamboo wood, by the bamboo wood hot bending being processed into feet, handrail, backrest and chair circle, again feet, handrail, backrest and chair circle are gluedd joint the whole pedestal that is combined into chair dexterously, not only give full play to extension, the vertical applied force of bamboo wood, the characteristics of hot bending handling ease, in the structure of simplifying chair, also satisfied the structural strength requirement of chair, in addition, the seat face is to be interwoven in length and breadth by knitting bar, cause and sit the flexible and permeability of mask, use comfortable.The utility model is that a kind of design is ingenious, can large-scale production, and simple for structure stable, and can meet the bamboo armchair of popular aesthetic requirement.
