CN2489655Y - Chair back - Google Patents

Abstract

The utility model discloses the seat back of the chair comprises frame, the dictyosome, registrate frame, the frame is the cavity framework that corresponds back of the chair shape, the dictyosome is made by soft materials and closely coats the frame outer fringe, the registrate frame is the cavity type body of making by hard material to set up the indent annular that supplies to embed the frame in the place ahead end limit, set up a plurality of rigid coupling holes in its annular, after the dictyosome combines with the frame end limit imbed in the annular of registrate frame, and alternate rigid coupling hole and annular rigid coupling by the rigid coupling component. After the chair back is assembled, the strength and the supporting safety of the chair back can be improved by the nesting frame, the frame can be wrapped by the nesting frame to improve the integrity of the assembly, and the aesthetic feeling of the assembly of the chair back can be improved by the modeling of the nesting frame.

Description

Chair back

The utility model relates to a kind of Chair back, mainly refers to a kind of assembling globality, support safety and assemble variational Chair back promoted.

Seat is one of necessary furniture of people.Known seat has multiple different types, and for promoting seat air ventilation comfortableness, known seat adopts the design of breathable mesh back.Fig. 4,5 is depicted as one of the mesh back structure of commonly seeing, mainly form by a framework 1 ' and a dictyosome 2 ', wherein: framework 1 ' is the hard hollow framework of corresponding chair back shape, dictyosome 2 ' is by the soft material manufacturing, and closely coat the outer rim of framework 1 ', make dictyosome 2 ' can cover framework 1 ', and make the chair back lie by the time can support by framework 1 ' and lie by weight, and reach ventilated comfortable purpose by the areola of dictyosome 2 '.

Yet aforementioned structure still has following shortcoming when implementing:

1. the chair back only supports by the framework of being located in the dictyosome 2 ' 1 ', easily causes framework 1 ' distortion or fracture when lying by power greatly, thereby causes danger.

2. the shape that is shaped as associated frame members 1 ' after the chair back makes up, tool assembling variability.

3. still can obviously see after the assembling and show framework 1 ', cause the not good situation of assembling globality by the areola of dictyosome 2 '.

In view of above-mentioned, the purpose of this utility model provides a kind of the enhancement and assembles globality, support safety and assemble variational Chair back.

The purpose of this utility model is achieved through the following technical solutions:

A kind of Chair back comprises framework and dictyosome, and framework is the hollow framework of corresponding chair back shape, and dictyosome is made by soft material, and closely coats the framework outer rim, it is characterized in that:

Also comprise the fit frame, this fit frame is the hollow molding body of being made by hard material, and its place ahead ora terminalis is provided with and supplies to set the interior concave ring groove of framework, and some coupling holes are set in the annular groove;

The ora terminalis of framework embeds in the annular groove of fit frame, and is affixed by interspersed coupling hole of affixed element and annular groove.

Advantage of the present utility model: can promote chair back intensity and support safety by the fit frame after the combination, framework can be coated with by the fit frame promotes composite entity, and can be by the moulding of fit frame to promote chair back assembling variability aesthetical effect.

Describe in detail below in conjunction with drawings and Examples.

Fig. 1,2 is respectively decomposing schematic representation and the combination schematic diagram of the utility model embodiment:

Fig. 3 is the combination cross-sectional schematic of the utility model embodiment;

Fig. 4,5 is respectively the decomposing schematic representation and the combination schematic diagram of known products.

See also Fig. 1 to Fig. 3, the utility model mainly is made up of framework 1, dictyosome 2, fit frame 3, framework 1 is the hollow framework of corresponding chair back shape, dictyosome 2 is by the soft material manufacturing, and running-on 21 and slide fastener 22 be set in the bottom, make dictyosome 2 wear framework 1 by running-on 21, and again driving fit slide fastener 22 so that dictyosome 2 closely coats framework 1 outer rims;

Fit frame 3 is the hollow molding body of being made by hard material, and can be for the interior concave ring groove 31 of setting framework 1 in the place ahead ora terminalis setting, and in annular groove 31 appropriate locations some coupling holes 32 is set.

Dictyosome 2 with the ora terminalis of framework 1 is embedded in the annular groove 31 of fit frame 3 after framework 1 engages, and it is affixed with annular groove 31 by affixed element 34 interspersed coupling holes 32, can promote chair back intensity and support safety by fit frame 3 after the combination, framework 1 is coated with by fit frame 3 promotes composite entity, and can be by 3 moulding of fit frame to promote chair back assembling variability aesthetic feeling.

Claims (1)

1. A seat back, comprising a frame and a net body, the frame is a hollow frame corresponding to the shape of the chair back, the net body is made of soft material, and tightly covers the outer edge of the frame, characterized in that: It also includes a fitting frame, the fitting frame is a hollow molded body made of hard material, the front edge of which is provided with a concave ring groove for embedding the frame, and a number of fastening holes are arranged in the ring groove; The end edge of the frame is inserted into the annular groove of the fitting frame, and the fixing element is inserted through the fixing hole to be fixedly connected to the annular groove.
