Mattress for evenly gathering and dispersing human body gravity

Abstract

A mattress for evenly gathering and dispersing human body gravity comprises elastic surface layer connecting cloth (1), elastic support frames (2), lateral connecting cloth (3), a filling region (4), granular fillers (5), a filler inlet/outlet (6), lower connecting cloth (7), a foot limiting belt (8), a leg limiting belt (9), hip limiting belts (10) and a back limiting belt (11) (limiting belts for short). The width of each of the limiting belts (8, 9, 10, 11) is less than that of the filling region. Upper ends and lower ends of the limiting belts (8, 9, 10, 11) are separately connected to an upper cloth layer and a lower cloth layer. When the mattress is stressed by human body gravity, the granular fillers automatically move towards a gravity-free region and fill a gap between the human body and the mattress, so as to provide a larger balanced stress surface for the human body and realize balancing of the human body gravity. The mattress is self-adaptive to a posture of lying on the side or lying on the back, so that no pillow is required. The mattress has functions of improving blood circulation and relieving fatigue of joints and muscles, and can avoid discomfort due to uneven stress. The mattress is partitioned into one or more independent filling regions by lateral upright partitioning cloth (12), so that the mattress can be used by one or more persons.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

(10) As shown in FIG. 1 and FIG. 3, the present invention is implemented as below. The structure of a mattress for evenly gathering and dispersing human body gravity is as shown in FIG. 5, FIG. 6, FIG. 7 and FIG. 8. The mattress includes elastic surface layer connecting cloth 1, elastic support frames 2, lateral connecting cloth 3, a filling region 4, granular fillers 5, a filler inlet/outlet 6, lower connecting cloth 7, a foot limiting belt 8, a leg limiting belt 9, hip limiting belts 10 and a back limiting belt 11, characterized in that upper surfaces of the two elastic support frames 2 are connected to the elastic surface layer connecting cloth 1 while lower surfaces thereof are connected to the lower connecting cloth 7; front sides and rear sides of the two elastic support frames 2 are connected to the lateral connecting cloth 3; the filler inlet/outlet 6 is provided on the lateral connecting cloth 3; a space formed by the elastic support frames 2, the upper elastic connecting cloth 1, the lower connecting cloth 7 and the lateral connecting cloth 3 is the filling region 4 in which the granular fillers 5 are filled, and the foot limiting belt 8, the leg limiting belt 9, the hip limiting belts 10 and the back limiting belt 11, which are arranged in parallel, are provided in the filling region 4, as shown in FIG. 5; an upper end and a lower end of each of the foot limiting belt 8, the leg limiting belt 9, the hip limiting belts 10 and the back limiting belt 11 are connected to the upper elastic connecting cloth 1 and the lower connecting cloth 7, respectively, and the width of each of the foot limiting belt 8, the leg limiting belt 9, the hip limiting belts 10 and the back limiting belt 11 is less than that of the filling region 4, such that a passage 14 substantially perpendicular to the limiting belts for flow of the granular fillers 5 is formed on each side of the limiting belts; the passage 14 communicates with the areas limited by the limiting belts. The granular fillers 5 are movable granules of a spherical or oval structure. Such a structure enables the granular fillers 5 to quickly roll.

(11) There are two hip limiting belts 10. A supporting region for the hip is partitioned into two regions by the hip limiting belts, so as to reduce the flowability of the granular fillers 5 in the hip region and enhance the stability of support.

(12) The lower connecting cloth 7 is composite reticulate sandwich cloth to enhance the elasticity of the mattress surface.

(13) As shown in FIG. 4, one piece of lateral connecting cloth 3 located on the front and rear sides of the two elastic support frames 2 and close to the foot limiting belt 8 is replaced by an elastic support frame 2. Such a structure enables the mattress to have elastic support frames in three adjacent directions so as to strengthen the structure of the mattress.

(14) The fillers in the elastic support frames 2 refer to elastic material, for example, polyurethane foam or hollow cotton. As shown in FIG. 6, lateral upright isolating cloth 13, used for isolating the granular fillers 5, is provided on a side of the elastic support frames 2 close to the filling region 4.

(15) In order to improve the applicability of the mattress, the mattress may be manufactured into a double-bed mattress structure. The structure thereof will be described as below.

(16) As shown in FIG. 2, at least one piece of lateral upright partitioning cloth 12 is provided on the mattress for evenly gathering and dispersing human body gravity in a direction vertical to each of the limiting belts. The filling region 4 is at least partitioned into two identical independent filling regions by the lateral upright partitioning cloth. An upper end and a lower end of the lateral upright partitioning cloth 12 are connected to the elastic surface layer connecting cloth 1 and the lower connecting cloth 7, respectively. Partitioned by the lateral upright partitioning cloth 12, the mattress may form identical filling regions for bearing two persons independently.

(17) The implementation and working principle of the mattress of the present invention are as follows: the elastic support frames 2 are filled with flexible material, for example, polyurethane foam or hollow cotton, as a skeleton, and the granular fillers 5 are formed by foaming polystyrene (EPS) or polypropylene (EPP). During manufacturing, the elastic support frames 2 are fixed by seaming the elastic surface layer connecting cloth 1, the lower connecting cloth 7 and the lateral connecting cloth 3 together, so as to form a mattress skeleton in a regular shape; and then, the granular fillers 5 are filled into the filling region 4 from the filler inlet/outlet 6, and the mattress is shaped as the granular fillers 5 are continuously filled. When in use, the granular fillers 5 in the filling region 4 move due to different pressures and sizes of human bodies. Since each part of the human body has a different pressure on the mattress, the granular fillers 5 will move according to different pressures, so as to self-adapt to the shape of the human body and realize balancing of the pressure, thus to evenly balance and buffer the pressure of the human body coming into contact with the mattress. Due to the structural design of the foot limiting belt 8, the leg limiting belt 9, the hip limiting belts 10 and the back limiting belt 11, the granular fillers 5 move within corresponding regions of the foot limiting belt 8, the leg limiting belt 9, the hip limiting belts 10 and the back limiting belt 11. The foot limiting belt 8, the leg limiting belt 9, the hip limiting belts 10 and the back limiting belt 11 play an important role in buffering the granular fillers 5 and limiting the large-scale irregular movement of the granular fillers. In the present invention, under the human body gravity, the stressed fillers in the mattress move towards a gravity-free region, and the shape of the mattress is changed by the coordination of the elastic surface layer and the limiting belts. First, the pressure at a part highly stressed by the human body is dispersed; second, gaps corresponding to the shoulders, elbows, neck, spine, knees, ankles and other parts are filled to provide a balanced stress surface for the human body, so that fatigue or damage of the human body resulted from uneven stress may be avoided. By establishing a gravity balance relationship between the human body and the mattress, low quality of sleep, caused by the strain and pain of the shoulders, neck, lumbar vertebra, knees, ankles and other parts due to the stress of gravity to human body parts and improper postures and by the coldness, is solved. The present invention changes the conventional mattress concept, and no pillow is required during sleeping.
