Description

Sofa backrest displacement structure

Technical field

The utility model relates to the office appliance field, and particularly sofa device field specifically is meant a kind of sofa backrest displacement structure.

Background technology

In the modern life and the work, people are more and more higher to the pursuit of the level of comfort of indoor various furniture, and wherein the most widely used is exactly sofa.And in the prior art, present commercially available various sofas, majority is a fixed dimension, can not change.Its shortcoming is: can not satisfy the needs of human body under different sitting postures, can not satisfy the people's of different height builds size needs, can not satisfy the needs that cooperate the varying environment style.Cause and take uncomfortablely, the use crowd is limited, and it is single only to be fit to environment, and the stiff dull environment of style has brought certain inconvenience with regard to the live and work to people like this.

The utility model content

The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, a kind of placement location that can adjust backrest as required flexibly is provided and use specification, simple in structure, cost is lower, easy to use, satisfy multiple build crowd use, firm and durable, the scope of application apparatus for placing of sofa backrest comparatively widely.

In order to realize above-mentioned purpose, sofa backrest displacement structure of the present utility model has following formation:

This sofa backrest displacement structure, the handrail and the backrest that comprise the sofa main body seat surface left and right sides, its main feature is, described each armrest rear end corresponding position has each groove, described backrest is bar-shaped, its middle part is convex to side protuberance, and described backrest both ends are movable respectively to be embedded in the groove of each handrail.

The shape of the groove of the armrest rear end of this sofa backrest displacement structure and the shape of cross section at backrest both ends are complementary.

The armrest rear end groove of this sofa backrest displacement structure be shaped as square, the shape of cross section at described backrest both ends also is a square.

The longitudinal cross-section of the convex protuberance at the backrest middle part of this sofa backrest displacement structure can be square, rectangle, semicircle, waveform or trapezoidal.

Adopted the apparatus for placing of the sofa backrest of this utility model, because backrest is flush-mounted in the groove at handrail rear portion by the both ends activity, and the backrest middle part has the convex protuberance, thereby can be positioned in the sofa main body by four direction, adjustment by the backrest modes of emplacement reaches four kinds of uses of a sofa specification, four kinds are used sight, build crowd's not of the same race needs have been satisfied, not only novel structure is simple, and cost is lower, easy to use, flexible and changeable, firm and durable, the scope of application is comparatively extensive, brings great convenience for people's live and work.

The specific embodiment

In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.

See also shown in Figure 1, sofa device of the present utility model, comprise: main body 1, backrest 2, wherein, main body about 1 two armrest rear ends are a groove 11, described backrest 2 is bar-shaped, its middle part is convex 22 to side protuberance, described backrest 2 both ends 21 are movable respectively to be embedded in the groove 11 of each handrail, wherein the shape of cross section at the shape of this groove 11 and backrest 2 both ends 21 is complementary, in the present embodiment, the armrest rear end groove 11 of this sofa backrest displacement structure be shaped as square, the shape of cross section at described backrest 2 both ends 21 also is a square, can certainly adopt other suitable matched shape as required.

Simultaneously, the longitudinal cross-section of the convex at backrest 2 middle parts of this sofa backrest displacement structure protuberance 22 is square, can certainly adopt rectangle, semicircle, waveform or trapezoidal as required.

See also shown in Figure 2ly again, backrest 2 is placed on the main body 1, make the convex of backrest 2 front ends swell 22 directions backward, both ends 21 snap in the square indentations 11 on the body 1.This moment, whole sofa outward appearance was upright, and vision is penetrating, was fit to formal occasion and used; Seat surface 12 degree of depth of sofa main body 1 are darker, and the backrest 2 and part broad that make progress parallel with horizontal plane is fit to the user and is fixed against among the sofa than the lowland with the posture loosened, center of gravity, and arm can be supported on the backrest naturally.

See also shown in Figure 3ly again, backrest 2 is placed on the main body 1, make the convex of backrest 2 front ends swell 22 directions upwards, both ends 21 snap in the square indentations 11 on the body 1.This moment, whole sofa outward appearance was irregular square, and vision is penetrating, was fit to unofficial occasion and used; Seat surface 12 degree of depth of sofa main body 1 are darker, and backrest 2 strong points are higher relatively, and the people that suitable build is bigger uses.

See also shown in Figure 4ly again, backrest 2 is placed on the main body 1, the convex protuberance 22 of backrest 2 front ends is directed downwards, both ends 21 snap in the square indentations 11 on the body 1.This moment, whole sofa outward appearance was upright, was fit to formal occasion and used; Seat surface 12 degree of depth of sofa main body 1 are bigger, and backrest 2 strong points are relatively low, and vision is not penetrating, and the sense of security is stronger.

See also shown in Figure 5ly again, backrest 2 is placed on the main body 1, make the convex of backrest 2 front ends swell 22 directions forward, both ends 21 snap in the square indentations 11 on the body 1.This moment, whole sofa outward appearance was irregular, and vision is penetrating, was fit to unofficial occasion and used; Seat surface 12 degree of depth of sofa main body 1 are more shallow, and backrest 2 strong points are relatively low, are fit to the less crowd of build and use, and what also suitable user straightened one's clothes and sit properly is seated at wherein.

Adopted the apparatus for placing of above-mentioned sofa backrest, because backrest 2 is flush-mounted in the groove 11 at handrail rear portion by the both ends activity, and the backrest middle part has convex protuberance 22, thereby can be positioned in the sofa main body 1 by four direction, adjustment by backrest 2 modes of emplacements reaches four kinds of uses of a sofa specification, four kinds are used sight, build crowd's not of the same race needs have been satisfied, not only novel structure is simple, and cost is lower, easy to use, flexible and changeable, firm and durable, the scope of application is comparatively extensive, brings great convenience for people's live and work.

In this specification, the utility model is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
