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 are certain difficulties, 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 frame, making the product shape change

Embodiment approach

[0028] Such as Figure 1 to Figure 10 As shown, the present invention discloses a sponge sofa structure, which includes a Styrofoam foamed Styrofoam sofa base 1, and the outer surface of the Styrofoam sofa base 1 is integrally formed. Soak with sponge (PolyurethaneFoam) layer 2. The thickness of the sponge layer 2 is greater than or equal to 1cm.

[0029] Such as figure 1 As shown, the styrofoam sofa base 1 includes a seating surface 11 and a surrounding surface 12 supporting the seating surface 11, and the sponge layer 2 is directly integrally foamed on the outer surface of the seating surface 11 and the surrounding surface 12, while sitting On the surface 11, sofa backrest 3 and sofa armrest 4 are directly foamed. The sponge can be made of hard foam to ensure the support strength of the sofa backrest 3 and the sofa armrest 4. Of course, the support strength of the sofa backrest 3 and the sofa armrest 4 can be bound by leather or cloth outsourced to the sofa.

Abstract

The invention discloses a sponge sofa structure, which comprises a styrofoam sofa base formed by styrofoam foaming, and a sponge layer is integrally foamed on the top surface or the outer surface of the styrofoam sofa base. The sponge sofa structure has the characteristics of simple manufacture technology, easy controlled appearance, high production efficiency and low production cost; in addition, because the styrofoam material is low in price, and has certain support strength and support toughness, the styrofoam material can effectively replace a part of characteristics of hard sponge, the use amount of sponge can be reduced, the material cost of the whole product can be reduced; furthermore, the sponge layer is integrally foamed on the surface of the styrofoam sofa base, is firmly combined with the surface of the styrofoam sofa base, and is not easy to get loose, and the service life of the product can be ensured.

Description

technical field [0001] The invention relates to a furniture product, 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 are certain difficulties, 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...
