Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bed mattress, especially a bed mattress with three-ring springs. BACKGROUND

[0002] The bed mattress in prior art is evenly arranged with multiple ordinary springs, and each ordinary spring is basically structure symmetrical in left-right direction, the reaction force direction of these ordinary springs after compression is vertically upward, and the person sleeping on the bed mattress is supported. Although the bed mattress with ordinary springs has no problem in support, it is insufficient in protection for the person who likes to turn over on the side, for example, if the person turns over on the side to the left side multiple times, it is easy to roll off from the left side of the bed mattress. SUMMARY

[0003] The utility model aims at giving a bed mattress with three-ring springs, which can prevent the person from rolling off the bed mattress when turning over on the same side multiple times to a certain extent.

[0004] A bed mattress with three-ring springs, comprising a bed mattress body, a plurality of three-ring springs are arranged on the bed mattress body; the three-ring spring comprises top, middle and bottom three layers, a circle of steel wires is arranged on the bottom layer, the end of the steel wire is located on the right side of the bottom layer, the end of the steel wire is coiled upward by half to the middle layer and then coiled upward by half to the right side of the top layer, and then the steel wire is coiled by one circle, the bending part is protruded to the left to form a side protrusion part; the three-ring springs are arranged on the bed mattress body, wherein the side protrusion part of the three-ring spring located on the left side of the self-symmetry axis of the bed mattress is directed to the left, and the side protrusion part of the three-ring spring located on the right side of the self-symmetry axis of the bed mattress is directed to the right.

[0005] Further, four bed mattress edge guards are arranged on the upper, lower, left and right edges of the bed mattress body respectively, the side protrusion part of the three-ring spring located on the leftmost side is arranged on the left bed mattress edge guard, and the side protrusion part of the three-ring spring located on the rightmost side is arranged on the right bed mattress edge guard.

[0006] Further, the right side of the middle layer is left empty to form a side concave avoiding part, and the side concave avoiding part can accommodate the side protrusion part of the adjacent three-ring spring.

[0007] Further, the three-ring spring is an independent bagged spring.

[0008] Further, a plurality of buffer pads are arranged on the top of the three-ring spring.

[0009] The beneficial effect is that the person has the risk of falling only when sleeping on one side of the bed and turning over to the side. For example, the person sleeps on the left half of the bed, in the left half of the bed, the three-ring spring left part has three layers of steel wires, the top ring, the side bulge part and the bottom ring, and the right part only has two layers of steel wires, the top ring and the bottom ring, the compression degree of the right part of the spring is greater than that of the left part, so that the left half of the bed is slightly inclined to the right after being compressed, and the person is not easy to turn over to the left side, reducing the risk of falling. Similarly, the person sleeping on the right half of the bed is not easy to turn over to the right side. In addition, if the person sleeps in the center of the bed, the left half of the bed is slightly inclined to the right, and the right half of the bed is slightly inclined to the left, which is like wrapping the person, so that the person feels better wrapping and comfort.

[0014] The utility model creation will be further explained in detail in combination with specific implementation manners.

[0015] As Figure 3 shown, the three-ring spring 6 includes upper, middle and lower three layers, the lower layer is provided with a circle of steel wires, the end of the steel wire is located at the right side of the lower layer, the end of the steel wire is left obliquely wound for half a circle to the middle layer, and then the right oblique up winding half a circle is connected to the right side of the top ring to the upper layer, and then a circle is wound, and the bending part protrudes to the left to form the side bulge part 3.

[0016] As Figure 1 shown, the bed mattress given by the utility model is provided with four bed mattress edge protections 1 on the upper, lower, left and right four edges of the bed mattress body. A plurality of three-ring springs 6 are arranged in the left part of the bed mattress body (i.e. the left half of the bed mattress) left to the symmetry axis 7 of the bed mattress body, the side bulge parts 3 of the three-ring springs 6 are directed to the left, and the side bulge part 3 of the three-ring spring 6 located at the leftmost is arranged on the left bed mattress edge protection 1. Similarly, a plurality of three-ring springs 6 are arranged in the right part of the bed mattress body (i.e. the right half of the bed mattress) right to the symmetry axis 7 of the bed mattress body, the side bulge parts 3 of the three-ring springs 6 are directed to the right, and the side bulge part 3 of the three-ring spring 6 located at the rightmost is arranged on the left bed mattress edge protection 1. As Figure 2As shown, the person 9 sleeps in the center of the mattress, and the left half of the mattress is slightly tilted to the right and down, because: the left part of the three-ring spring 6 has three layers of steel wires, i.e., the top ring, the side protrusion 3 and the bottom ring, while the right part has only two layers of steel wires, i.e., the top ring and the bottom ring, so the compression degree of the right part is greater than that of the left part, which makes the left half of the mattress slightly tilted to the right and down after being compressed. Similarly, the right half of the mattress is slightly tilted to the left and down, so that the person 9 feels better wrapped and comfortable.

[0017] As shown, Figure 3 The right side of the middle layer is left empty to form a side concave avoiding part 10. If the three-ring springs 6 need to be closely arranged side by side, the side concave avoiding part 10 can accommodate the side protrusion 3 of the adjacent three-ring spring 6. The three-ring spring 6 is an independent bagged spring, and the top of the three-ring spring 6 is laid with multiple layers of cushion pads (not shown in the figure).

[0018] The above description is only an embodiment of the present application, and does not limit the patent protection range. Those skilled in the art can make non-substantial changes or substitutions on the basis of the present application, and still fall within the scope of the patent protection.
