A mattress with adjustable firmness

Abstract

The invention relates to a mattress with adjustable hardness, which relates to the technical field of bedding. The adjustment of the hardness of the existing mattress is very troublesome. This solution includes an upper pad and a lower pad. The lower pad includes a rigid frame and a hardness adjustment assembly located in the rigid frame. The hardness adjustment assembly includes several elastic support pieces and linear pullers. The directions are arranged in a straight line, the lower end of the elastic support piece is connected to the rigid frame by rotation, and the rotation axis of the elastic support piece is set horizontally and perpendicular to the long side direction of the lower pad, and the upper pad is supported on the upper end of the elastic support piece; each elastic support piece The upper ends are all connected to the linear puller, and the linear puller is connected to the end of the rigid frame along the long side of the lower pad, and one side of the rigid frame is installed with a positioning assembly for limiting the movement of the linear puller along its pulling direction . In this solution, the hardness of the lower mattress is adjusted by controlling the hardness adjusting component, thereby more conveniently changing the hardness of the entire mattress.

Description

technical field [0001] The invention relates to the technical field of bedding, in particular to a mattress with adjustable hardness. Background technique [0002] About one-third of a person's life is spent in sleep. Having a good sleep is a necessary condition for maintaining human health. Therefore, it is very important to choose a mattress with appropriate hardness. Most of the existing mattresses on the market are mattresses with constant hardness, which cannot be adapted to the needs of different people, especially when different members of a family use the same mattress, it may not be suitable for all members situation, thus creating a bad experience for the unsuitable party. [0003] With the development of the times, a class of mattresses with adjustable hardness have also appeared in the prior art, such as the Chinese invention patent application with the application publication number CN109475236A, which discloses a mattress, including a base part located at the ...

Problems solved by technology

[0004] Although the above-mentioned type of mattress can realize hardness adjustment, the entire inner core needs to be replaced each time the hardness adjustment is made. Since the inner core is usually large, it is often difficult for one member to be easily realized, which eventually leads to very difficult and impractical adjustment of the hardness.
