Description

Technical Field

[0001] This invention relates to the field of mattress technology, specifically to a self-adaptive supportive back mattress. Background Technology

[0002] As a sleep tool that comes into close contact with the human body, the support performance of a mattress directly affects sleep quality and spinal health. In order to make the mattress conform to the natural physiological curves of the human body and provide differentiated support for different parts such as the shoulders, waist and hips, and to avoid the waist being unsupported or excessively compressed in certain areas, adaptive support mattresses are generally used.

[0003] Existing adaptive support mattresses typically have multiple independent air chambers inside the mattress. Each air chamber is inflated and deflated individually by an external inflation device, and the expansion and contraction of the air chambers support the user's spine. However, because the air chambers are independently designed, different sleeping positions result in varying pressure on the air chambers. This means the air chambers cannot provide differentiated support for different parts of the user's body, such as the waist and shoulders, leading to ineffective spinal support and poor spinal protection. Furthermore, since different users have different heights and body types, and the air chambers are installed independently inside the mattress, they cannot be adjusted according to the user's body shape and height, resulting in poor performance.

[0004] In view of this, we propose an adaptive support spine-supporting mattress. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive support spinal support mattress that solves the problems of poor spinal protection effect of airbags and the inability to adjust the position of airbag protection according to the user's height and body shape.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An adaptive support back mattress includes a base plate, the top of which is provided with a plurality of limiting frames, each limiting frame having a fixing mechanism on both sides, the fixing mechanism being fixed to the base plate, an airbag being provided inside each limiting frame, and a cushioning pad being provided above the base plate, the top of the airbag extending out of the limiting frame and contacting the bottom of the cushioning pad. Each airbag is equipped with an air guide tube at one end, and a connecting tube is installed on the opposite side of two adjacent air guide tubes. A venting tube is connected between two adjacent connecting tubes through a flange, and a second valve is installed on the connecting tube at one end of the venting tube. Each of the air guide tubes is connected to an air inlet tube at one end, and a one-way valve is connected to one end of the air inlet tube.

[0007] Preferably, the fixing mechanism includes strip connecting plates fixed on both sides of the bottom of the limiting frame. Each strip connecting plate has a mounting hole at its top, and each mounting hole has a bolt inside. A threaded sleeve is installed inside the base plate, and the bottom end of each bolt extends into the corresponding threaded sleeve and is threadedly connected to the threaded sleeve.

[0008] Preferably, a first valve is installed at the end of each of the air guide pipes near the air inlet pipe.

[0009] Preferably, each airbag is provided with a plurality of first elastic straps inside, and both ends of each first elastic strap are fixed to the two sides inside the airbag. Furthermore, each airbag is provided with a plurality of second elastic straps inside, and both ends of the second elastic straps are fixed to the upper and lower ends inside the airbag.

[0010] Preferably, adjacent second elastic bands are staggered with the first elastic bands, and there is a gap between adjacent second elastic bands and the first elastic bands.

[0011] Preferably, a fixing plate is installed at both ends of the vent pipe, and a plurality of capillary tubes are installed between the two fixing plates, the capillary tubes being connected to the connecting pipe.

[0012] Preferably, the base plate and the cushioning pad are provided with a mattress cover, the mattress cover forms an accommodating space, the base plate and the cushioning pad are located in the accommodating space, and the sides of the base plate and the cushioning pad abut against the inner wall of the mattress cover.

[0013] Preferably, one end of the air duct passes through the mattress cover, and both the connecting pipe and the air duct are located outside the mattress cover.

[0014] Preferably, the top of the threaded sleeve is flush with the top of the base plate.

[0015] Preferably, the base plate is made of high-density polyester foam, and the cushioning pad is made of slow-rebound memory foam.

[0016] By employing the above technical solution, the present invention provides a self-adaptive support mattress for spinal health. It possesses at least the following beneficial effects: 1. This invention, by setting up multiple independent airbags and through air guide tubes, connecting tubes, ventilation tubes, and first and second valves, can flexibly control the connection status of airbags in different parts according to the user's body shape, and achieve zoned adaptive support.

[0017] 2. This invention uses capillary tubes to slowly diffuse the gas in the airbag to adjacent airbags when the shoulder is under pressure. At the same time, excess gas can be quickly transferred to the lumbar airbag through the cooperation of the air guide tube and the air inlet tube, causing it to rise. This dynamically adjusts the support force in each area, so that the human spine always maintains its natural physiological curvature, effectively relieving pressure on the lower back and improving the spinal protection effect.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] A self-adaptive support mattress, such as Figure 1 - Figure 5 As shown, an adaptive support back mattress includes a base plate 1, which is made of high-density polyester foam. The base plate 1 has a certain degree of hardness and is a porous material. During use, it can support the user and absorb low-frequency vibrations and airflow noise, preventing sound from being transmitted through the bed frame and thus improving the sound insulation effect.

[0022] like Figure 2 and Figure 4As shown, the top of the base plate 1 is provided with several limiting frames 9. Each limiting frame 9 has a fixing mechanism on both sides. The fixing mechanism is fixed to the base plate 1. The fixing mechanism includes strip connecting plates 12 fixed to the bottom sides of the limiting frame 9. Each strip connecting plate 12 has a mounting hole 19 on its top. Each mounting hole 19 has a bolt 13 inside. A threaded sleeve 18 is installed inside the base plate 1. The top of the threaded sleeve 18 is flush with the top of the base plate 1. The bottom end of each bolt 13 extends into the corresponding threaded sleeve 18 and is threadedly connected to the threaded sleeve 18. Through the cooperation of the bolt 13 and the threaded sleeve 18, the strip connecting plate 12 can be fixed together with the base plate 1, thereby fixing the limiting frame 9 to the base plate 1. During use, the limiting frame 9 will not move horizontally relative to the base plate 1.

[0023] like Figure 2 and Figure 3 As shown, each limiting frame 9 is equipped with an airbag 2 inside, and a cushioning pad 11 is provided above the base plate 1. The top of the airbag 2 extends out of the limiting frame 9 and contacts the bottom of the cushioning pad 11. The cushioning pad 11 is made of slow rebound memory foam, which is used to conform to the curve of the human body to disperse the initial body pressure, absorb the shear force of turning over, and isolate the hard touch of the airbag 2 and the limiting frame 9 below, so as to cushion the user's body and keep the user comfortable.

[0024] It should be noted that, as Figure 1 As shown, a mattress cover 10 is provided on the outside of the base plate 1 and the cushioning pad 11. The inside of the mattress cover 10 forms an accommodating space, in which the base plate 1 and the cushioning pad 11 are located. The sides of the base plate 1 and the cushioning pad 11 abut against the inner wall of the mattress cover 10. The mattress cover 10 can limit the position of the base plate 1 and the cushioning pad 11, so that the cushioning pad 11 and the base plate 1 will not be misaligned during use.

[0025] like Figure 1 and Figure 2 As shown, each airbag 2 has an air guide tube 5 installed at one end, and a connecting tube 3 is installed on the opposite side of two adjacent air guide tubes 5. An air vent 6 is connected between two adjacent connecting tubes 3 through a flange 7, and a second valve 8 is installed on the connecting tube 3 at one end of the air vent 6. The opening and closing of the connecting tube 3 can be controlled by the second valve 8. In this way, during use, the user can control the opening and closing of the corresponding second valve 8 according to their own height and the position of sleeping on the mattress, connecting several airbags 2 located in the user's shoulders, several airbags 2 in the waist, and several airbags 2 in the buttocks and legs. The expansion and contraction of the airbags 2 support the user's spine, and the position of the working airbags 2 can be adjusted according to the user's body position.

[0026] like Figure 2 and Figure 5As shown, both ends of the ventilation tube 6 are equipped with fixing plates 16, and several capillary tubes 17 are installed between the two fixing plates 16. The capillary tubes 17 are connected to the connecting tube 3. In actual use, when the user turns over, the area of ​​the airbag 2 at the shoulder will decrease, which will increase the deformation of the airbag 2 at the shoulder. The air pressure inside the airbag 2 with greater deformation is greater than the air pressure inside the airbag 2 with less deformation. In this way, the air inside the airbag 2 with greater air pressure can be transported to the airbag 2 with less air pressure through the capillary tubes 17. The airflow is slow, so the deformation speed of the airbag 2 is slow, which can support the user's shoulder and protect the user's spine when sleeping.

[0027] like Figure 2 As shown, each air duct 5 is connected to an air inlet pipe 20 at one end. One end of the air inlet pipe 20 is connected to a one-way valve 21, and each air duct 5 is equipped with a first valve 4 near the end of the air inlet pipe 20. The airbags 2 used can be connected through the air duct 5 and the air inlet pipe 20. By controlling the opening and closing of the valve on the air duct 5, the airbag 2 located on the user's shoulder can be connected to the airbag 2 located on the user's waist and the airbags 2 located on the hip and legs. When the user turns over, the shoulder airbag 2 expands and delivers excess gas through the air inlet pipe 20 and along the corresponding air duct 5 to the waist airbag 2, causing the waist airbag 2 to inflate. This can support the user's lumbar spine and protect the user's spine.

[0028] It should be noted that, as Figure 5 As shown, each airbag 2 has several first elastic straps 14 inside, with both ends of each first elastic strap 14 fixed to the two sides inside the airbag 2. Each airbag 2 also has several second elastic straps 15 inside, with both ends of each second elastic strap 15 fixed to the upper and lower ends inside the airbag 2. Adjacent second elastic straps 15 are staggered with the first elastic straps 14, and there is a gap between adjacent second elastic straps 15 and first elastic straps 14. The first elastic straps 14 are used to generate approximately circumferential expansion when the airbag 2 is compressed and laterally inflated. The binding force restricts the radial expansion deformation of the airbag 2 and converts part of the lateral expansion force into an upward lifting force on the top wall of the airbag 2, which can prevent excessive sinking of the shoulder area when the user rolls over; the second elastic strap 15 can be used to limit the maximum upward elongation of the airbag 2 when it is inflated and lifted, ensuring that the lifting height of the airbag 2 in the waist area does not exceed the preset height; so that the airbag 2 can be limited to a safe deformation range in the vertical direction and maintain shape stability in the horizontal direction when compressed, avoiding spinal support instability due to excessive local deformation.

[0029] It should be noted that one end of the air duct 5 passes through the mattress cover 10, and both the connecting pipe 3 and the air duct 6 are located outside the mattress cover 10. This makes it convenient to operate because the air duct 5, the first valve 4 at the end, and the second valve 8 on the connecting pipe 3 are located outside the mattress cover 10.

[0030] When in use, the user opens the second valve 8 located on the user's shoulders, waist, and hips and legs according to their own body shape, so that several airbags 2 located on the user's shoulders are connected to each other, and several airbags 2 located on the user's waist and hips and legs are connected to each other. In this way, the airbags 2 can provide support and protection for users of different body shapes. After adjusting the position of the airbag 2, the user can open the corresponding first valve 4 and close the other first valves 4, and then inflate the air into the air inlet pipe 20. The air inlet pipe 20 delivers air along the corresponding air guide pipe 5 to the corresponding airbag 2, causing the airbag 2 to inflate to the preset height. Through the cooperation of the air inlet pipe 20 and the air guide pipe 5, the airbag 2 at the user's shoulder can be connected to the airbags 2 at the waist and hips and legs. When a user turns over in their sleep, the gas in the shoulder pressure airbag 2 is delivered to the connecting tube 3 through the air guide tube 5. After the airflow passes through the capillary tube 17 and is slowed down, it is delivered to another connecting tube 3 and slowly diffuses along another air guide tube 5 to the adjacent shoulder airbag 2, so that the pressure of the shoulder airbag 2 is evenly distributed. At the same time, the excess gas in the shoulder airbag 2 group quickly enters the air inlet tube 20 through the first valve 4 and the air guide tube 5, and flows rapidly into the waist airbag 2 along the air inlet tube 20 and the corresponding air guide tube 5, forcing the waist airbag 2 to overcome the constraint of the second elastic strap 15 and rise upward to support the user's waist. During this process, the first elastic strap 14 restricts the lateral expansion of the shoulder airbag 2 and converts part of the expansion force into a lifting force on the top, preventing excessive shoulder collapse. In this way, the mattress always keeps the human spine in its natural physiological curvature. At the same time, when the user turns over, it automatically increases the height of the lumbar support and buffers the shoulder pressure, keeping the spine in a natural state and protecting the user's spine.
