Description

A kind of sofa

Technical field

The utility model relates to a kind of furniture, especially relates to a kind of sofa.

Background technology

At present, the sofa that on the market some are more common, its structure mainly contains following several: a kind of is the sponge sofa, promptly directly lay sponge on hardboard, this sofa configuration is simple, and production cost is low, but after using a period of time, it is very poor that its elasticity can become, and whole sofa also is out of shape severity simultaneously, thereby has influence on comfortableness.Also has a kind of spring sofa that is, this sofa is owing to installed spring additional, its elasticity is more much better than sponge sofa, but, the user is generally reflected, than after long, sofa can be easy to generate distortion in use, and promptly rough phenomenon appears in the sofa surface, this mainly is because the uneven institute of its horizontal and vertical elasticity causes, during use, under the compressing of user's weight, the discontinuity of sofa, thereby the distortion that causes each position of sofa to produce under long term is also inconsistent, often a stressed or stressed bigger position can produce depression, and then to upper process, serious spring can penetrate sponge because elasticity is big at stressed less position.Above-mentioned these problems all are that the unreasonable structure owing to sofa itself causes, and these problems not only have influence on the comfortableness of use, and, go down for a long time, can bring bad influence to user healthy.

The utility model content

At existing in prior technology the problems referred to above, the purpose of this utility model be to provide a kind of rational in infrastructure, comfortableness good, durable in use, stressed in use evenly, on-deformable sofa.

The technical scheme that the utility model is taked for achieving the above object is: a kind of sofa, comprise support, spring layer, spongy layer, described support comprises a framework and be connected with some support bars on framework, spring layer comprises being installed in and is vertically some evenly distributed springs on the framework, the two ends of this spring all are fixed on the framework by clip, be installed in some ropes that are horizontally set on the framework and pass spring, on spring, also be horizontally arranged with one deck elastic cord, the two ends of elastic cord are fixed on the framework, are equipped with a spongy layer on elastic cord.

Of the present utility modelly further be set to: described framework is a quadra, and is connected with 4～8 support bars on framework, two centre positions that vertically are arranged on framework wherein, and all the other bevels are provided with.This set has not only improved the intensity of support, has effectively prevented the distortion of support, and has saved material.

One splinting layer is installed on the described framework.This set can further prevent the distortion of support, makes framework more firm, and has played the effect of supporting with framework.

Described spring adopts serpentine spring, has stability preferably; Described rope is a cotton cord, and cotton cord passes spring, has improved anti-impact force and has guaranteed that also spring is not yielding simultaneously.

Be equipped with a burlap layer between described elastic cord and the spongy layer.This set can balancing spring, elastic cord be subjected to dynamics, improve the balance of sofa, the people is not tilted above being sitting in and can prevent that sofa from sounding because of the spring friction.

Described spongy layer adopts high-density sponge.Adopting high-density sponge is in order to prevent strong spring perforation, and the comfortableness that improves sofa.

Be equipped with gum sprayed cotton or elastic cotton on the described spongy layer.The comfortableness that has improved sofa is set like this, makes the profile of sofa more apparent full simultaneously.

The beneficial effects of the utility model are: one, the sofa of the utility model manufacturing is more comfortable, softer; Two, in use, the stressed even dispersion of strong spring has solved yielding, the givey old trouble of sofa, makes sofa be with high resilience in gentle, can make sofa full for a long time, well-pressed, do not sink, indeformable; Three, this product has solved the moving spring cry of sofa seat for a long time, makes sofa not have the spring grating; Four, increase service life more than at least three times; Five, increase the fatigue strength of sponge and reduce loss more than 50%.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

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

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the Facad structure schematic diagram of framework described in the utility model and support bar;

Fig. 4 is the structural representation behind mounting spring, elastic cord and cotton cord on the support described in the utility model.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model comprises support 1, spring layer 2, spongy layer 3.

As shown in Figure 3, described support 1 comprises a quadra 11 and be connected with some support bars 12 on framework 11, concrete is to be connected with 4～8 support bars 12 on framework 11, two centre positions that vertically are arranged on framework 11 wherein, all the other bevels are provided with, this set has not only improved the intensity of support 1, has effectively prevented the distortion of support 1, and has saved material.See again shown in Fig. 1,, one deck splinting layer 13 is installed also on framework 11 in order to make framework 11 more firm.

As shown in Figure 4, spring layer 2 comprises being installed in and is vertically evenly distributed some springs 21 on the framework 11, the two ends of spring 21 all are fixed on the framework 11 by clip 22, in order to make spring 21 have good stable, described spring 21 can adopt serpentine spring, in order to strengthen the anti-impact force of spring 21, be horizontally arranged with pass spring 21 some ropes 23 and be fixed on the framework 11, rope 23 can adopt cotton cord, can ensure that like this all springs 21 are stressed, thereby spring 21 suffered impulsive forces are disperseed, for reducing the impulsive force of spring 21, can set up one deck elastic cord 24 on spring 21, elastic cord 24 is a horizontally set, and two ends are fixed on the framework 11.

Again as shown in Figure 1 and Figure 2, on elastic cord 24, be equipped with a spongy layer 3.Can add one deck burlap layer 25 between elastic cord 24 and spongy layer 3, its advantage is one can balancing spring 21, elastic cord 24 is stressed, improves the balance of sofa, and the people is not tilted above being sitting in; Two can prevent that sofa from sounding because of the spring friction.In order to prevent strong spring 21 perforation, described spongy layer 3 adopts high-density sponge.In order to improve the comfortableness of sofa, make the profile of sofa more apparent full simultaneously, on spongy layer 3, lay gum sprayed cotton or elastic cotton 33.The utility model also can coat a profile cover for seat 36 and reverse side and fix after above-mentioned the setting, can make profile more attractive in appearance.
