Abstract

A kind of chair, including chair face, chair legs and backrest, the chair face and backrest are integrally formed for molding, and the integrally formed chair face and backrest of being molded includes upper strata, lower floor and the middle interlayer between the upper and lower；The chair face is corner round rectangle in the arc-shaped, is the sphere of indent among rectangle, air-vent is provided with the sphere；The backrest is set with chair face into obtuse angle.Chair face of the present utility model and backrest are easily manufactured using the integrally formed structure of molding.The spherical structure design of inner concavity increases the compactness of chair face and human body on chair face, make chair face periphery uniform force, the load-bearing dynamics of chair is enhanced, and the setting of air-vent can ensure the permeability of chair, enhance the comfort level of people's summer seat period of the day from 11 p.m. to 1 a.m；Thermoplastic resin and continuous fiber braid mixing compression molding are used simultaneously, the mechanical property of chair is enhanced, extends the service life of chair.

Description

A kind of chair

Technical field

The utility model belongs to furniture, and in particular to a kind of chair.

Background technology

Traditional chair is made up of plastics or wood materials more, and chair is typically more heavy made of wood materials, and Need to link together between each part of chair, the chair robustness of this attachment structure is poor, and more bulky chair It is not easy to carry, it is fragile during transport, the labor intensity of worker is added, improves cost of transportation.And some Plastic chairs Or the usual intensity of stool is poor, chair causes the final damage of bird caging deformation because of discontinuity.

Utility model content

The purpose of this utility model is to provide a kind of light, uniform force and is not easy the chair of torsional deformation.

To achieve the above object, the utility model adopts the following technical scheme that：

A kind of chair, including chair face, chair legs and backrest, the chair face and backrest are integrally formed for molding, described Being molded integrally formed chair face and backrest includes upper strata, lower floor and the middle interlayer between the upper and lower；The chair Face is corner round rectangle in the arc-shaped, is the sphere of indent among rectangle, air-vent is provided with the sphere；It is described to lean on The back of the body is set with chair face into obtuse angle.

The upper strata is thermoplastic resin long fibre prepreg, and the middle interlayer is compiled for infiltrated treated continuous fiber Fabric, the lower floor are the thermoplastic long fiber compound not infiltrated.

The backrest bottom is provided with arc convex portion.

Hole is provided among the backrest top.

Chair face of the present utility model and backrest are easily manufactured using the integrally formed structure of molding.Indent on chair face The design of the spherical structure of shape increases the compactness of chair face and human body, makes chair face periphery uniform force, enhances chair Load-bearing dynamics, and the setting of air-vent can ensure the permeability of chair, enhance relaxing for people's summer seat period of the day from 11 p.m. to 1 a.m Appropriateness；Thermoplastic resin and continuous fiber braid mixing compression molding, the addition of continuous fiber braid, enhancing are used simultaneously The mechanical property of chair, makes uniform force, avoids that local pressure is uneven and the situation of torsional deformation, can become chair The thin intensity for not reducing chair while lighten, has saved production cost, has extended the service life of chair.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the integrally formed chair face of molding and backrest diagrammatic cross-section.

Embodiment

As depicted in figs. 1 and 2, a kind of chair, including chair face 5, chair legs 4 and backrest 1, chair face 5 and backrest 1 are mould Pressure is integrally formed, the integrally formed chair face 5 of the molding and backrest 1 include upper strata 21, lower floor 23 and in upper strata 21 and under Middle interlayer 22 between layer 23；Chair face 5 is corner round rectangle in the arc-shaped, is the sphere 6 of indent among rectangle, sphere Air-vent 7 is provided with 6；Backrest 1 is set with chair face 5 into obtuse angle.

Upper strata 21 is thermoplastic resin long fibre prepreg, and middle interlayer 22 is infiltrated treated continuous fiber braiding Thing, lower floor 23 are the thermoplastic long fiber compound not infiltrated.Thermoplastic resin and the shaping of continuous fiber braid composite coining Chair can improve the uniformity of chair stress, strengthen the integrally-built mechanical property of chair, make chair firm and durable.

The bottom of backrest 1 is provided with arc convex portion 3.The setting in backrest lower lobes portion can make human body lean on back When waist be brought into close contact backrest and waist is more loosened, cambered design adds comfort level.

Hole 2 is provided among the top of backrest 1.The hole on backrest top can play a part of ventilative radiating, while be moved in people Hand handle is facilitated to hold the chair back when dynamic chair.

Claims (4)
