Integral covered bagged spring cushion

Abstract

The invention belongs to an integral covered bagged spring cushion comprising a plurality of spiral spring rows and two layers of seaming cloth, wherein seams of the two layers of seaming cloth are distributed between every two adjacent spiral spring rows; an upper separating seam of an upper cover body formed by the upper layer of cloth is distributed among individual springs of the spiral spring rows; a lower separating seam of a lower cover body formed by the lower layer of cloth is distributed among the individual springs of the spiral spring rows; and the individual springs of the plurality of spiral spring rows are distributed in a bag body seamed by the upper cover body formed by the upper layer of cloth and the lower cover body formed by the lower layer of cloth. The integral covered bagged spring cushion is simple in structure, low in cost, more environment-friendly, comfortable in use and durable.

Description

technical field [0001] The invention belongs to the technical field of sofas or mattress furniture, and relates to a spring cushion used for sofas and beds. Background technique [0002] With the development of spring mattresses, pocket springs are used to improve the comfort of sofas or beds with the characteristics of good air permeability, low interference, and hygienic softness. Existing pocket spring sofa cushions and pocket spring mattresses are mainly formed by bonding several pocket springs 2-1 with glue 1-1, such as figure 1 shown. With this bonding structure, there are the following problems: [0003] (1) A large amount of glue is required for bonding, because the glue used is mainly composed of chemical raw materials, which will have a certain impact on human health and the environment; and because the glue used is expensive, the production cost is increased. [0004] (2) With the accumulation of time, the bonding performance of the glue, that is, the viscosity...

AI Technical Summary

Problems solved by technology

[0003] (1) A large amount of glue is required for bonding, because the glue used is mainly composed of chemical raw materials, which will have a certain impact on human health and the environment; and because the glue used is expensive, the production cost is increased

[0004] (2) With the accumulation of time, the adhesive performance of the glue, that is, the viscosity, will decrease. When people squeeze the pocket spring again, splits between the pocket spring rows are easy to occur

[0005] (3) The production process is cumbersome. It is necessary to produce the pocket springs first, then cut the pocket springs into strips, and then glue the pocket spring strips into mats through the bonding combination machine.

[0006] (4) Since the existing bonded bag spring pad is bonded with glue, if it is used on an electric folding bed, the glue will be easily damaged after repeated folding and pulling for a long time

[0007] In summary, the existing spring-bonded sofa cushions and spring mattresses are complicated to produce, have poor structural stability, are easily displaced and deformed between pocket spring rows, have high production costs, pollute the environment, and affect people's health.
