Sponge sofa or sponge stool structure

Abstract

The invention discloses a sponge sofa or sponge stool structure which comprises a low-density sponge foaming forming sofa base or low-density sponge foaming forming stool base with the foaming density of 10-35 kg / m<3>, wherein a high-density sponge cladding layer with the foaming density of 35-60 kg / m<3> is integrally foamed on the outer surface of the base; the hardness of the sponge sofa base or the sponge stool base is Share A 20+; the hardness of the sponge cladding layer is 30-80 Kgf. The sponge sofa structure has the characteristics of simple manufacturing process, shape controllability, high production efficiency and low manufacturing cost. In addition, a low-density sponge of the sponge sofa base or the sponge stool base is relatively low in price and light in weight and has certain supporting strength and supporting toughness. Therefore, the consumption of a high-density sponge can be reduced, and the material cost and weight of a whole sponge sofa or stool can be further reduced. Moreover, the sponge cladding layer is integrally foamed on the outer surface of the sponge sofa base or the sponge stool base, is firmly attached to the surface of the base and is unlikely to loosen, and thus the service life of the sponge sofa or stool is guaranteed.

Description

technical field [0001] The invention relates to a furniture product, in particular to a structure of a sponge sofa and a sponge stool. Background technique [0002] At present, commonly used sponges are divided into three types according to their structure: high-density sponges, medium-density sponges, and low-density sponges. Among them, the high-density sponge has many holes, is full, and has good air permeability and elasticity; sponge products have gradually become popular in people's lives, including seats, sofas, mattresses and other household items made of sponge. [0003] And the making of sponge stool, sponge sofa mainly is to coat sponge layer outside a base body at present, outside the sponge layer, coat surface material to form again. Due to the elasticity of the sponge, multiple fastening points (such as fastening nails, etc.) must be used to make the desired shape when it is coated on the substrate, and it needs to be prepared by manual operation. It is diffi...

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 desired shape when it is coated on the substrate, and it needs to be prepared by manual operation. It is difficult and the production efficiency is low; according to the current preparation method of secondary coating, it is difficult to guarantee the uniformity of the product shape; in addition, if the fastening nails fall off, the sponge layer will be separated from the substrate, causing the product shape to change. Variety

In addition, based on the above problems, a one-piece sponge sofa or sponge stool has been developed. The sponge sofa or sponge stool of this design is heavy and inconvenient to use in daily life. At the same time, it also has problems such as high cost and poor elastic memory.
