Description

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 some on the market are more common, its structure mainly contains following several, and 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, thereby have 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, after growing in use, sofa can be easy to generate distortion, and promptly rough phenomenon appears in the sofa surface, and 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, thus 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, stressed less position then because elasticity is big to upper process.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 is to provide a kind of rational in infrastructure, sofa that comfortableness is good.

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, it is characterized in that: support comprises a quadra 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, 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, spongy layer is arranged on the top of spring layer, spongy layer comprises first spongy layer, second spongy layer, gum sprayed cotton, be equipped with some packed strong springs at first spongy layer, on packed strong spring, lay second spongy layer, on second spongy layer, lay gum sprayed cotton.

Of the present utility modelly further be set to: described support bar is set to three, a centre position that vertically is arranged on framework, and all the other two become the diagonally opposing corner setting.This set has not only improved the intensity of support, has effectively prevented the distortion of support, and has saved material.

Of the present utility modelly further be set to: the two ends of spring all are fixed on the framework by clip, and described spring adopts serpentine spring.This set can make spring stable, not loosening, has played fastening effect.

Of the present utility modelly further be set to: described rope is a cotton cord.This set has improved anti-impact force.

Of the present utility modelly further be set to: be equipped with one deck burlap layer on the described elastic cord.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.

Of the present utility modelly further be set to: density sponge during first spongy layer adopts, second spongy layer adopts high-density sponge.Adopting high-density sponge is in order to prevent packed strong spring perforation, and the comfortableness that improves sofa.

The beneficial effects of the utility model are: one, the sofa of the utility model manufacturing is more comfortable, softer; Two, the utility model can solve the old trouble that sofa subsides easily, makes sofa be with high resilience in gentle; Three, in public places, because the utilization rate height more is easy to generate problem, the utility model can make sofa full for a long time, well-pressed, sagging, indeformable; Four, the utility model has solved the moving spring cry of sofa seat for a long time, makes sofa not have the spring grating; Five, increase service life more than at least three times; Six, increase the fatigue strength of sponge and reduce loss more than 50%.
