Abstract

A low-resilience pocket spring comprising at least two layers of accommodating cavities (10) provided in a vertical direction and composed of fabrics, wherein the accommodating cavity (10) in the uppermost layer is composed of a first fabric (11), and an elastic member (20) is packaged and sealed therein, the remaining accommodating cavities (10) are composed of a second fabric (12), and a spring member (30) is sealed and packaged therein. The air permeability of the first fabric (11) is lower than that of the second fabric (12). Since the uppermost accommodating cavity (10) is composed of a fabric having low air permeability, the uppermost accommodating cavity (10) forms a relatively sealed cavity and causes poor air circulation between the interior and exterior thereof, so as to enable the volume of the uppermost accommodating cavity (10) to change slowly when a pressure is applied thereon or released therefrom, such that the uppermost layer of a pocket spring layer achieves low-resilience characteristics similar to memory foam, and effectively improves the comfort level of the mattress.

Description

Slow rebound spring bag spring

Technical field

The invention relates to the technical field of pocket springs, in particular to a pocket spring.

Background technique

The bag spring is formed by enclosing a single spring package in a bag, and each bag spring is connected in sequence to form a bag spring string, and the bag spring string is arranged and bonded to form a bag spring mattress. In order to improve the comfort of the bag spring mattress in the prior art, a piece of memory foam, latex and the like having a slow resilience property are usually disposed on the top surface of the bag spring mattress, and the slow rebound material property is used for the human body. Provides good uniform support. However, in the prior art, by adding a material having a slow resilience such as a memory cotton or a latex, the manufacturing cost is inevitably increased, and the integrity of the mattress structure is affected.

Summary of the invention

The technical problem to be solved by the present invention is to provide a slow rebound type pocket spring with stable structure and good comfort.

A technical solution adopted to solve the above technical problem: a slow rebound type pocket spring comprising at least two upper and lower accommodating chambers formed of a cloth, and the accommodating chamber at the topmost layer is formed and wrapped by the first cloth The flexible individual is encapsulated, and the remaining receiving chambers are formed by the second cloth and wrapped with a spring individual, the first cloth having a lower gas permeability than the second cloth.

Further, the elastic body is one of a spring, a sponge and a gel.

Further, the first cloth and the second cloth are both non-woven fabrics having vent holes, and the vent hole diameter of the first cloth is smaller than the vent hole diameter of the second cloth; or the vent hole of the first cloth The distribution density is smaller than the distribution density of the vent holes of the second cloth.

Further, the first cloth and the second cloth are all the same non-woven fabric, and the first cloth is coated with a plastic film so that the first cloth has lower gas permeability than the second cloth.

Advantageous Effects: In the slow rebound type bagged spring, since the topmost accommodating chamber is made of a cloth having low gas permeability, the topmost accommodating chamber constitutes a relatively sealed chamber, and the gas outside the cavity is poor in fluidity. The volume change of the topmost accommodating chamber under pressure or pressure release is slow, so that the topmost pocket spring layer has a slow rebound property like a memory cotton, which can effectively improve the comfort of the mattress.

2 is a schematic cross-sectional view showing a structure in which an elastic body is a spring according to an embodiment of the present invention;

3 is a schematic cross-sectional view showing a structure in which an elastic body is a sponge or a gel according to an embodiment of the present invention;

4 is a schematic cross-sectional view showing a structure in which an elastic body is a sponge or a gel according to an embodiment of the present invention.

Detailed ways

1 to 4, a slow rebound type pocket spring of the present invention comprises at least two upper and lower accommodating chambers 10 formed of cloth, and the accommodating chamber 10 at the topmost layer is formed by the first cloth 11 and wrapped. The elastic body 20, the remaining accommodating chamber 10 is formed by the second cloth 12 and wrapped with the spring individual 30, the air permeability of the first cloth 11 is lower than that of the second cloth 12, so that the upper and lower layers accommodate the chamber 10. The breathability is different.

Specifically, the first cloth 11 and the second cloth 12 may each adopt a non-woven fabric having a vent hole, and the first cloth 11 and the second cloth 12 may be the same cloth but the vent holes are different, or the first cloth 11 and The second cloth 12 is composed of two pieces of cloth joined together. In order to achieve poor gas permeability of the accommodating chamber 10 of the top layer, the vent hole diameter of the first cloth 11 may be set smaller than the vent hole diameter of the second cloth 12. Of course, the diameter of the vent holes can also be designed to be the same, and the distribution density of the air holes on the cloth is changed so that the distribution density of the vent holes of the first cloth 11 is smaller than the distribution density of the vent holes of the second cloth 12.

In addition, the first cloth 11 and the second cloth 12 may also be made of a nonwoven fabric having the same venting holes, but the first cloth 11 is coated with a plastic film to reduce the gas permeability of the first cloth 11 to reach the first cloth. The gas permeability of 11 is lower than that of the second cloth 12.

The accommodating chamber 10 of the top layer is constructed of a cloth having a low gas permeability, and the accommodating chamber 10 of the top layer constitutes a relatively sealed chamber, and the flow of air from the chamber to the outside of the chamber or the outside of the chamber to the chamber is slow, so that the accommodating chamber of the top layer 10 The internal volume changes slowly under pressure or pressure release state, especially in the state of pressure release, because the volume change in the accommodating chamber 10 is slow, which restricts the rapid rebound of the elastic individual 20 in the cavity, so that the top layer is packed. The spring layer has a slow rebounding property similar to memory foam, which effectively improves the comfort of the mattress. The elastic body 20 can be a spring, a sponge or a gel.

The slow rebound spring of the invention consists of two layers of a top layer and a bottom layer. The bag spring layer on the top layer has a slow rebounding property similar to that of a memory cotton, and the bottom pocket spring layer is a traditional pocket spring layer, which can provide good performance. Supporting power.

The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above-described embodiments, and can be made without departing from the spirit of the invention within the scope of the knowledge of those skilled in the art. Various changes.
