Sponge sofa structure

Abstract

The invention discloses a sponge sofa structure. The sponge sofa structure comprises a hard sofa primary structure; a layer of soft sponge layer at least covers on the upper surfaces of back rest part and sitting part of the sofa primary structure; wherein a plurality of springs are at least arranged in the sitting part of the soft primary structure, each spring is arranged in the manner that the axis is vertical to the surface of the sitting part. The springs are arranged in a sofa base during a foaming moulding process of the sofa base, the springs not only have higher supporting strength and buffer property but also can effectively reduce the usage amount and weight of hard sofa primary structure materials, therefore the manufacturing cost of the sponge sofa is reduced effectively, and the market competitiveness of products is enhanced.

Description

technical field [0001] The invention relates to a sofa, in particular to a sponge sofa structure. Background technique [0002] Sofa is the most popular furniture item, which is comfortable to sit on and has various forms. However, in addition to wooden sofas, sponges are essential materials in the basic composition of leather sofas and cloth sofas. The making of sofa is mainly to coat sponge layer outside a sofa frame at present, and then coat surface leather material or cloth quality material outside sponge layer to form. Due to the elasticity of the sponge, multiple fastening points (such as fastening nails, etc.) must be used to make the required shape when it is covered on the sofa frame, and it needs to be prepared manually. Therefore, not only There is a certain degree of difficulty, and the production efficiency is low. [0003] Therefore, the applicant in this case invented a sponge sofa with high production efficiency and good service life. It mainly made a hard...

AI Technical Summary

Problems solved by technology

Due to the elasticity of the sponge, multiple fastening points (such as fastening nails, etc.) must be used to make the required shape when it is covered on the sofa frame, and it needs to be prepared manually. Therefore, not only There is a certain degree of difficulty, and the production efficiency is low

[0003] Therefore, the applicant in this case invented a sponge sofa with high production efficiency and good service life. It mainly made a hard sofa base with supporting strength first, and then foamed a sponge layer on the outer surface of the hard sofa base, and then Formed by wrapping the outer surface, the hard sofa base is mainly made of hard sponge, so the weight of the whole sofa is relatively large, and the cushioning performance is not ideal. Based on this, the sponge sofa still needs improvement
