SUMMARY

[0003] The utility model aims at giving a kind of anti-collapse edge bed mattress equipped with M-shaped spring, which can avoid the collapse of the edge of bed tail of bed mattress body to some extent.

[0004] A kind of anti-collapse edge bed mattress equipped with M-shaped spring, the edge of bed tail of bed mattress body is equipped with multiple M-shaped springs, these M-shaped springs adhere to the inner side wall of bed mattress body, each M-shaped spring includes upper portion left and right horizontal wire, front and rear horizontal spring ring and lower portion left and right horizontal wire from top to bottom, the left end of upper portion left and right horizontal wire is bent and turns to oblique lower right and then extends the front end of front and rear horizontal spring ring, the left end of lower portion left and right horizontal wire is bent and turns to oblique upper right and then extends the rear end of front and rear horizontal spring ring, the right end of upper portion left and right horizontal wire of these M-shaped springs is equipped with front and rear horizontal upper limit rod, and the right end of lower portion left and right horizontal wire is equipped with front and rear horizontal lower limit rod;These M-shaped springs are arranged left and right, the upper and lower two bending places of each M-shaped spring are all to left, and the upper and lower two limit rods of each M-shaped spring are respectively clamped into the upper and lower two bending places of the M-shaped spring adjacent to right.

[0005] Furthermore, the right end of the upper left and right transverse steel wires of the M-shaped spring turns to extend obliquely downward to the right to form an upper rounded bend, and the right end of the lower left and right transverse steel wires turns to extend obliquely upward to the right to form a lower rounded bend; the upper and lower limiting rods are respectively mounted on the upper and lower rounded bends.

[0006] Furthermore, the upper and lower limit rods face opposite directions.

[0007] Furthermore, the upper limit lever faces horizontally backward, and the lower limit lever faces horizontally forward.

[0008] Furthermore, multiple pocket support springs are installed in the non-edge areas of the mattress body.

[0009] Furthermore, it includes multiple layers of cushioning pads laid on the plurality of pocket support springs and the M-shaped springs.

[0010] The beneficial effects are as follows: The M-shaped springs in this anti-collapse mattress do not require assembly into the existing double M-shaped springs. The lengths of the upper and lower left and right horizontal steel wires are only half that of the double M-shaped springs, making them less prone to bending and deformation under load, thus preventing the edge of the mattress from collapsing. Furthermore, because the upper and lower limiting rods of each M-shaped spring are respectively engaged in the upper and lower bends of the adjacent M-shaped spring on the right, the right ends of the upper and lower left and right horizontal steel wires of the M-shaped springs are supported by the spring coils of the adjacent M-shaped springs, while the left ends are supported by their own spring coils. Therefore, both ends of the upper and lower left and right horizontal steel wires are supported by spring coils, making them less prone to bending and deformation. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to specific embodiments.

[0017] likeFigure 1 As shown, the M-shaped spring includes, from top to bottom, upper left and right transverse steel wires, front and rear transverse spring coils 4, and lower left and right transverse steel wires. The left end of the upper left and right transverse steel wires bends downwards and to the right before extending to connect with the front end of the front and rear transverse spring coils 4. The left end of the lower left and right transverse steel wires bends upwards and to the right before extending to connect with the rear end of the front and rear transverse spring coils 4. Figure 2 As shown, the upper left and right horizontal steel wires of the M-shaped spring turn at their right ends and extend diagonally downwards to the right to form an upper rounded bend 6. The upper rounded bend 6 is provided with a horizontally rearward upper limit rod 7. The lower left and right horizontal steel wires turn at their right ends and extend diagonally upwards to the right to form a lower rounded bend 6. The lower rounded bend 6 is provided with a horizontally forward lower limit rod 7.

[0018] like Figure 4 As shown, multiple M-shaped springs are installed near the foot of the mattress body 1. These M-shaped springs are arranged horizontally from left to right, with the upper and lower bends 3 of each M-shaped spring facing left. The upper and lower limit rods 7 of each M-shaped spring respectively engage with the upper and lower bends 3 of the adjacent M-shaped spring on the right, preventing the left M-shaped spring from shifting to the left and preventing the right M-shaped spring from shifting to the right. These M-shaped springs are close to the inner wall of the mattress body 1 to support the foot of the mattress body 1. The existing double M-shaped springs have the following disadvantages: the upper horizontal steel wire of the M-shaped spring is 16cm long. If two M-shaped springs are joined together to form a double M-shaped spring as in the current technology, the upper steel wire of the double M-shaped spring will be 32cm long. Only two spring coils 4 are used for support near the left and right ends, and the midpoint is relatively easy to bend and deform under pressure. The M-shaped spring of this invention provides support to the right end of the upper left and right horizontal steel wires by inserting the upper and lower limiting rods 7 into the upper and lower bends 3 of the adjacent M-shaped springs on the right. This solves the problem that the right end of a single M-shaped spring cannot be supported, eliminating the need to assemble a double M-shaped spring for support on the right end. The upper left and right horizontal steel wires can maintain their original length of 16cm without needing to be extended to the 32cm of a double M-shaped spring. Therefore, they are not easily bent or deformed under pressure.

[0019] Preferably, multiple pocket support springs are installed in the non-edge areas of the mattress body 1, and multiple layers of cushioning pads are laid on these pocket support springs and these M-shaped springs.

[0020] The above description is merely an embodiment of this utility model and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on this utility model will still fall within the scope of patent protection.
