Prestressed mattress and design method thereof

Abstract

The invention relates to the field of life supplies of people, and in particular relates to a prestressed mattress and a design method thereof. The prestressed mattress comprises an elastic layer and a prestressed component which is used for pre-compressing the elastic layer so as to enable the elastic layer to obtain a prestressing force. When the intensity of pressure of a human body to the prestressed mattress is less than f0, the prestressed mattress is not deformed; when the intensity of pressure of the human body to the prestressed mattress is more than f0, the prestressed mattress is deformed, and the part of the intensity of pressure which is more than f0 has linear relation with a rigidity coefficient Kb; therefore, the designed prestressed mattress has double parameters, so that the types of mattresses can be enriched, the performances of the mattress are diversified, and the prestressed mattress can well meet various different demands of people.

Description

[0001] The application number of the present invention is 201210436469.0, the application date is November 05, 2012, the name is "spring mattress elastic support assembly and spring mattress" and the application number is 201210498808.8, the application date is November 29, 2012, the name The domestic priority of the two Chinese patent applications for "a kind of spring mattress". technical field [0002] The invention relates to the field of daily necessities for human beings, in particular to a prestressed mattress and a design method thereof. Background technique [0003] About one-third of people's life is spent in bed, and bed is a very important necessity in human life. The main types of elastic mattresses in the prior art are as follows: spring mattresses, latex elastic mattresses, sponge elastic mattresses and 3D fiber elastic mattresses. The elastic layer in the mattress is compressed and deformed to provide protection against the human body. In the field of mattre...

AI Technical Summary

Problems solved by technology

The main types of elastic mattresses in the prior art are as follows: spring mattresses, latex elastic mattresses, sponge elastic mattresses and 3D fiber elastic mattresses. The elastic layer in the mattress is compressed and deformed to provide protection against the human body. In the field of mattress design, people can only control the softness and hardness of the mattress by adjusting the stiffness coefficient of the elastic layer, and the method is single, such as figure 1 As shown, the deformation of the elastic layer has a linear relationship with the pressure. As long as there is pressure, there will be deformation, and the degree of softness and hardness of the mattress is fixed. A mattress that is too soft will cause the body to sink, and a mattress that is too hard will cause the body to suffer. If the force is too concentrated, even if you choose a mattress with suitable hardness and softness, the support of the mattress to the person will vary greatly due to different sleeping positions

[0004] The curve of the human body and the distribution of gravity determine that the pressure of the limbs on the mattress is small, the pressure of the trunk on the mattress is average, and the pressure of the head and buttocks on the mattress increases sharply, so a better mattress should be when the pressure is higher. When the pressure is small or average, the deformation of the mattress is small or even no deformation, so as to obtain the effect of strong supporting force and hard mattress. The area of ​​the support can be increased to disperse the pressure, reduce the pressure, and obtain a soft feeling. The existing mattresses cannot achieve the above effects, and the existing design methods cannot design the above mattresses.
