Description

Technical Field

[0001] The present invention relates to the technical field of household articles, and particularly to a spinal care and decompression spring mattress suitable for sedentary sub-healthy people. Background Art

[0002] With the change of modern social work patterns, sitting for a long time has become the norm for many professional groups, especially in office, driving, learning and family environments. Although the long-term sedentary state can improve efficiency, it poses various threats to human health. Among them, spinal health problems are particularly significant, including changes in the physiological curve of the spine, degeneration or herniation of the intervertebral disc, increased lumbar spine pressure, etc., which in turn lead to symptoms such as chronic low back pain, nerve compression and related lower limb numbness. In addition, since the sedentary state will keep the muscles of the neck, shoulders and waist in a tense state for a long time, it will lead to limited blood circulation and gradually increased muscle fatigue, thus causing muscle stiffness and soreness, further reducing the comfort and activity ability of the human body.

[0003] At the same time, sitting for a long time will also have an implicit impact on mental health. Maintaining a single posture for a long time is often accompanied by problems such as mental tension, inattention and accumulation of psychological pressure. These factors will further affect the stability of the biological clock, leading to sleep disorders or even long-term insomnia problems. The decline in sleep quality not only weakens the body's recovery ability, but also forms a vicious cycle of "sub-healthy state".

[0004] At present, the design of traditional mattresses on the market mainly focuses on generality and lacks special optimization for the physiological characteristics of sedentary people. Ordinary mattresses have limited performance in terms of elastic distribution, support uniformity and dynamic adaptability, and it is difficult to effectively relieve spinal pressure or meet the support needs of different parts of the human body. For example, an overly soft mattress may cause the body to sink too deep, resulting in spinal deformation, while an overly hard mattress will exert too much pressure on local bones, affecting blood circulation. That is to say, the existing technologies mainly focus on single-functional improvement for the health problems caused by sitting for a long time, lacking systematic design.

[0005] Therefore, in view of the above background, how to design a mattress product developed specifically for sedentary sub-healthy people, which can not only provide accurate spinal support for users, relieve muscle tension, but also improve the sleep environment for users, enhance comfort and sleep quality, is a problem that those skilled in the art need to solve. Summary of the Invention

[0006] The embodiment of the present invention provides a spinal care and decompression spring mattress suitable for sedentary sub-healthy people, aiming to provide a mattress for users that can achieve spinal support, relieve muscle tension, and improve sleep quality.

[0007] An embodiment of the present invention provides a spinal protection and decompression spring mattress suitable for sedentary sub-healthy people, including a bed perimeter.

[0016] When the progressive decompression padding layer uses high-elastic foam material, the high-elastic foam material is located below the memory elastic foam and / or dynamic response fibers;

[0017] The progressive decompression padding layer further includes an elastic support layer located at the lowermost layer.

[0018] Preferably, the elastic support layer is made of polyurethane sponge, and the density of the polyurethane sponge is greater than 30 kg / m 3 。

[0037] Next, please refer to Figures 1 to 3 , the embodiments of the present invention provide a spinal protection and decompression spring mattress suitable for sedentary sub - healthy people, including a bed perimeter 4. The bed perimeter 4 is sequentially provided with a self - adapting and stabilizing spinal protection spring layer 3, a progressive decompression padding layer 2 and a fabric composite layer 1 from the inside to the outside;

[0038] Among them, the self - adapting and stabilizing spinal protection spring layer 3 includes multi - strand double - layer springs with non - linear deformation characteristics and supporting performance;

[0039] The progressive pressure-relieving cushion layer 2 is made of any two or more materials among dynamic response fibers, new memory elastic foam, latex, and high-elasticity foam, and the hardness of the progressive pressure-relieving cushion layer 2 gradually increases from top to bottom;

[0040] The fabric composite layer 1 includes a knitted fabric layer C11, a flexible fiber layer C12, and a flexible foam layer C13 in sequence from top to bottom.

[0041] In this embodiment, the spinal protection and pressure-relieving spring mattress includes a fabric composite layer 1, a progressive pressure-relieving cushion layer 2, an adaptive stable spinal protection spring layer 3, and a bed perimeter 4 wrapped around the outside from top to bottom. This mattress provides a strong reverse support for the body through multi-strand double-layer springs with non-linear deformation characteristics and support performance, preventing the body from sinking excessively, and ensuring the mechanical stability and anti-interference performance of the overall structure, realizing the dynamic adaptation of spinal support for sedentary people with different body types, weights, and sleeping postures. Through the gradient layering and dynamic adaptability design of the progressive pressure-relieving cushion layer 2, the problems of "pressure fault" and "hanging feeling" existing in the traditional pressure-relieving layer are solved, ensuring that the pressure is gradually and evenly conducted from the surface layer to the lower layer, and realizing the pressure dispersion and support from the surface to the deep layer. The fabric composite layer 1 is also made of knitted fabric, flexible fibers, etc. to improve the ductility and conformability of the fabric composite layer 1 to better adapt to the dynamic characteristics of the multi-layer structure of the mattress.

[0042] The spinal protection spring mattress provided in this embodiment combines the principles of ergonomics, modern materials science, and health rehabilitation science, and provides a systematic solution to health problems such as spinal burden, muscle tension, and sleep quality decline caused by long-term sitting through innovative multi-level support design, personalized cushion structure, and material combination. In particular, the spinal protection spring mattress provided in this embodiment is not only applicable to sedentary professional groups, but also brings new health solutions to special groups such as lumbar rehabilitation patients, athletes, and the elderly.

[0043] In one embodiment, the multi-strand double-layer spring is a double-layer waist-drum-shaped spring, and the double-layer waist-drum-shaped spring includes an upper-layer spring 31 and a lower-layer spring 32. Among them, the stiffness of the upper-layer spring 31 is less than the stiffness of the lower-layer spring 32.

[0044] Specifically, the compression displacement range of the upper-layer spring 31 during use is 15 - 25 mm, and the compression displacement range of the lower-layer spring 32 during use is 5 - 15 mm.

[0045] In this embodiment, a double-layer waist-drum-shaped spring is used as the multi-strand double-layer spring. The double-layer waist-drum-shaped spring consists of an upper and a lower layer structure, which can achieve the non-linear deformation characteristics of the spring mattress core layer and the dynamic response ability of the support performance. Among them, the upper-layer spring 31 is mainly composed of springs with a relatively low stiffness, which can flexibly conform to the body curve and provide flexible support; the lower-layer spring 32 uses high-stiffness springs (greater than the upper-layer stiffness) to provide a stable basic support for the core area of the body (such as the lumbar spine) and prevent excessive sagging. The preferred upper-layer spring 31 should have a compression displacement range of 15-25 mm during use, so that it can easily adapt to the fine adjustment of the human body curve under a small pressure. The main function of the upper-layer spring 31 is to provide flexible support, adapt to the shape and weight distribution of different parts of the human body, ensure uniform contact surface pressure, and reduce the local compression on the skin and soft tissues. The preferred lower-layer spring 32 should have a compression displacement range of 5-15 mm during use to withstand greater pressure and provide stable support. The lower-layer spring 32 is responsible for maintaining the overall support stability of the mattress and the spinal protection function, and avoiding problems such as spinal curvature or insufficient support caused by excessive sagging. The upper and lower layer springs 32 must work together within the elastic range to achieve dynamic pressure transfer and adaptive adjustment, while ensuring that there is no obvious break in pressure transfer.

[0046] Here, in combination with Figure 4 , the double-layer waist-drum-shaped spring adopts a unique structural design. Through the shape optimization with a wider middle part and gradually narrowing ends (for example, the diameter ratio of the middle position of the spring to the opening position at both ends of the spring is 1:1.2-2), the mechanical properties of the spring can be significantly improved, and thus the special health needs of sedentary people can be met. Its core advantage is that it can gradually disperse the force when bearing the human body pressure, avoid the pressure concentration on sensitive areas such as the spine or intervertebral disc, and effectively reduce the burden on the spine and the compression on the intervertebral disc. At the same time, the double-layer waist-drum-shaped spring, relying on its excellent elastic deformation characteristics, can absorb the vibration brought by turning over or dynamic pressure, significantly reduce the interference of the mattress to the partner or other areas, and thus further improve the shock absorption performance.

[0047] In addition, as Figure 5 shown, the double-layer waist-drum-shaped springs are arranged according to the honeycomb structure rule.

[0048] Arranging the double-layer waist-drum-shaped springs according to the honeycomb structure rule can not only improve the uniformity of the overall support, but also make the mattress have higher structural stability. Moreover, the honeycomb arrangement can optimize the spring distribution in a limited space, enabling each spring to be independently stressed and cooperate with each other, thus avoiding the problems of collapse or pressure concentration caused by excessive linkage of traditional springs.

[0049] Furthermore, the double-layer waist drum-shaped spring can dynamically adjust the support force according to different body weights and sleeping postures. Especially in the area where lumbar pressure concentrates due to long-term sitting, the dynamic self-adaptability of the spring helps relieve fatigue and maintain the natural physiological curve of the spine.

[0050] In a specific embodiment, the multi-strand double-layer spring is made by winding or bundling multiple steel wires.

[0051] The multi-strand double-layer spring has excellent fatigue resistance and elastic recovery ability. Even after long-term use, it can maintain a stable support force. At the same time, the multi-strand double-layer spring is composed of multiple thinner steel wires through winding or bundling, forming a composite spring structure as a whole. When vibration is transmitted to the multi-strand double-layer spring, the force will be dispersed to each strand of steel wire, thus reducing the vibration transmission efficiency. The slight sliding, friction or torsion between the multi-strand steel wires further dissipates the vibration energy, thereby achieving the damping effect.

[0052] In this embodiment, the self-adaptive stable spinal protection spring layer 3 is composed of multi-strand double-layer waist drum-shaped springs arranged in a honeycomb pattern, which can significantly improve the spinal support effect, stability and damping performance of the mattress, especially meeting the usage needs of people who sit for a long time and users with special health requirements.

[0053] In one embodiment, when the progressive pressure relief padding layer 2 uses memory elastic foam and / or dynamic response fiber, the memory elastic foam and / or dynamic response fiber is located in the uppermost layer of the progressive pressure relief padding layer 2;

[0054] When the progressive pressure relief padding layer 2 uses high-elastic foam material, the high-elastic foam material is located below the memory elastic foam and / or dynamic response fiber;

[0055] The progressive pressure relief padding layer 2 further includes an elastic support layer C24 located in the lowermost layer.

[0056] Specifically, the elastic support layer C24 is made of polyurethane sponge, and the density of the polyurethane sponge is greater than 30 kg / m 3 .

[0057] In addition, the overall thickness of the progressive pressure relief padding layer 2 is 3 - 8 cm.

[0058] In this embodiment, the progressive pressure relief padding layer 2 adopts a gradient layering and dynamic adaptability design, solving the problems of "pressure fault" and "hanging feeling" of the traditional pressure relief layer, ensuring that the pressure is gradually and evenly conducted from the surface layer to the lower layer, so as to realize the pressure dispersion and support from the surface to the deep layer. The progressive pressure relief padding layer 2 can specifically be composed of two or more materials such as dynamic response fiber, new memory elastic foam, latex and high-elastic foam, and the hardness increases gradually from top to bottom, and the overall thickness is 3 - 8 centimeters.

[0059] In practical applications, if memory elastic foam and dynamic response fibers are selected for the progressive decompression cushioning layer 2, they are preferably placed on the upper surface layer of the progressive decompression cushioning layer 2, and dynamic response fibers and memory elastic foam can also be used in combination. If a high-elastic foam material is selected for the progressive decompression cushioning layer 2, the high-elastic foam material is arranged in the lower layer. At the same time, an elastic support layer C24 with a greater hardness is arranged at the bottom layer. And if both a high-elastic foam material and latex are selected, the latex material is arranged above the high-elastic foam material, and the high-elastic foam material is placed on top of the elastic support layer C24 with a greater hardness. This structural design helps to avoid the "funnel effect" or "hammock effect" in the cushioning layer. It should also be noted that the specific materials selected for the progressive decompression cushioning layer 2 can be set based on actual needs. For example Figure 2 As shown, the progressive decompression cushioning layer 2 sequentially includes a dynamic response fiber layer C21, a memory elastic foam layer C22, a latex layer C23, and an elastic support layer C24 from top to bottom.

[0060] In one embodiment, the knitted fabric layer is made by a flexible high-elastic knitting process.

[0061] The flexible fiber layer is made of any one or a combination of polyester fiber, viscose fiber, microfiber, and Lycra fiber.

[0062] The flexible foam layer is made of any one or a combination of polyurethane foam, latex foam, or bio-based foam material.

[0063] In addition, the thickness of the fabric composite layer 1 is 2 - 5 cm.

[0064] In this embodiment, the fabric composite layer 1 can be composed of an environmentally friendly knitted fabric, flexible fibers, flexible foam, and non-woven fabric, and is fixed by a quilting process with an independent pattern. The pattern size is less than 5 inches (12.7 cm) to ensure the stability and elasticity of the fabric composite layer 1, and the thickness of the fabric composite layer 1 is preferably selected between 2 - 5 cm.

[0065] Among them, the knitted fabric adopts a flexible high-elastic knitting process (a knitting technology that combines flexible materials with high-elastic properties, widely used in clothing, sports equipment, and functional textiles) to provide higher ductility and conformability, better adapting to the dynamic characteristics of the multi-layer structure of the mattress. When the user is sleeping, the knitted fabric can closely conform to the body curve. Further, through the optimization design of the surface mechanism, the soft touch of the knitted fabric can be enhanced. At the same time, the knitted fabric can also significantly suppress the friction sound between the fabric and the internal materials of the mattress, reducing the noise generated by dynamic movements such as turning over, thereby further enhancing the sleep experience. In addition, the durability of the fabric is improved, effectively avoiding pilling and wear during long-term use. Here, the optimization design of the surface mechanism specifically can include the optimization design of the micro-structure, such as increasing the surface roughness or texture, so that the direct contact area is reduced during the friction process, thereby reducing the friction force and the generation of friction sound. And, since the multi-layer structure of the mattress will undergo displacement and deformation during dynamic movement, in this embodiment, the fabric is designed to be able to flexibly adapt to this movement, thereby reducing the friction and noise caused by surface unevenness.

[0066] The flexible fiber is mixed with one or more of polyester fiber, viscose fiber, microfiber, and Lycra fiber. Preferably, a combination of 30%-50% polyester fiber and 50%-70% viscose fiber, or a combination of 50% polyester fiber and 50% microfiber is selected.

[0067] The flexible foam layer is composed of one or more of polyurethane foam, latex foam, or bio-based foam materials. Preferably, a combination of hydrophilic sponge and flexible polyurethane sponge is selected. Here, the hydrophilic sponge generally refers to a foam material with good hydrophilicity, and its main component generally belongs to polyurethane foam. This material has excellent water absorption and water retention capabilities under the action of specific chemical modification and additives, and is widely used in medical, household, and industrial applications. And, the hydrophilic sponge and the flexible polyurethane sponge are two different foam materials. The flexible polyurethane sponge is mainly used to provide comfort and support, suitable for products such as seat cushions and mattresses, and usually has good elasticity and plasticity. The hydrophilic sponge mainly emphasizes its water absorption and water retention capabilities, and is suitable for water treatment and application scenarios with strong absorbency.

[0068] In some actual application scenarios, sleep monitoring sensors can also be set on the mattress to monitor the user's sleep status in real time, such as key indicators like heart rate, breathing rate, and the number of turns. These data are sent to the user's smart device through the built-in wireless transmission module, enabling the user to understand their sleep quality at any time and adjust the mattress according to the monitored data, such as increasing elasticity or adjusting softness and hardness, etc., to obtain a more personalized sleep experience. The setting of sleep monitoring sensors not only improves the intelligence level of the mattress but also provides a scientific and convenient sleep health management solution for users.

[0069] Furthermore, a smart temperature control system can be equipped for the spinal protection and pressure relief spring mattress. This system can automatically adjust the temperature of the mattress according to the user's body temperature change, thereby providing a more comfortable sleep environment. Specifically, the smart temperature control system includes a temperature sensor, a controller, and a heating or cooling element. The temperature sensor is used to monitor the temperature of the mattress surface in real time, and the controller controls the working state of the heating or cooling element based on the data feedback from the sensor to keep the mattress within an appropriate temperature range. This smart temperature control system not only improves the comfort of the mattress but also helps to improve sleep quality and reduce insomnia or discomfort caused by temperature changes. In specific implementation, the smart temperature control system can be designed as a multi-layer structure, where the temperature sensor and the heating or cooling element are respectively embedded in different layers of the mattress. For example, the temperature sensor can be set in the fabric composite layer 1 to accurately sense the temperature of the contact surface between the user and the mattress; while the heating or cooling element can be set in the progressive pressure relief padding layer 2 or the adaptive stable spinal protection spring layer 3 to achieve the adjustment of the overall temperature of the mattress. Preferably, the smart temperature control system can also be integrated with the sleep monitoring sensor to achieve more intelligent sleep management. For example, when the sleep monitoring sensor detects that the user enters the deep sleep state, the smart temperature control system can automatically lower the temperature of the mattress to provide a more comfortable sleep environment for the user.

[0070] In addition, a reinforcement border can be set on the side edge part of the bed perimeter 4 of the mattress to enhance the supporting force of the mattress edge and prevent collapse caused by sitting or lying on the edge for a long time. The reinforcement border can be made of hard materials, such as hard fiberboard or high-density foam, to ensure the stability of the edge structure and extend the service life of the mattress. Further, on the bottom of the mattress, a non-slip bottom layer is set, and this layer can be made of non-slip materials, such as non-slip fabric or rubber material, to increase the friction between the mattress and the bed frame, prevent the mattress from sliding or shifting during use, and ensure the safety and stability of use.

[0071] Generally speaking, compared with the prior art, the mattress provided by the embodiment of the present invention has the following beneficial effects:

[0072] (1) In the embodiment of the present invention, a multi-strand double-layer spring design is adopted in the mattress, which has non-linear deformation characteristics and the dynamic response ability of the support performance. During the pressure-bearing process, the upper hourglass-shaped spring compresses first due to its structural characteristics, providing a gentle buffer, conforming to the subtle curves of the body, providing a soft support effect, and effectively avoiding local high pressure on the body. When the pressure gradually increases, the upper spring enters the compression saturation state, and the pressure is transmitted to the lower spring, providing a strong reverse support for the body, preventing the body from sinking excessively, and ensuring the mechanical stability and anti-interference performance of the overall structure. Therefore, this spring mattress can achieve the dynamic self-adaptation of spinal support for sedentary people with different body types, weights, and sleeping postures. At the same time, through the dispersion of vibration energy, non-linear deformation, multi-frequency absorption, and internal damping effects, the multi-strand double-layer spring can effectively reduce the intensity and frequency of vibration transmission, and has a significant shock-absorbing effect. Its unique mechanical characteristics and stability make it an ideal choice in elastic shock-absorbing devices.

[0073] (2) In the embodiment of the present invention, a knitted fabric and a special surface mechanism optimization design are adopted, which not only improves the ductility and conformability of the fabric composite layer 1, but also better adapts to the dynamic characteristics of the multi-layer structure of the mattress. At the same time, it significantly suppresses the friction sound between the fabric and the internal materials of the mattress, reduces the noise generated by dynamic actions such as turning over, and combines the double-effect sound insulation effect of the spring to reduce noise and shock, effectively improving the sleep experience of sedentary people.

[0074] (3) The gradient layering and dynamic adaptability design of the mattress upholstery layer proposed in the embodiment of the present invention can solve the problems of "pressure fault" and "hanging feeling" existing in the traditional pressure relief layer, ensure that the pressure is gradually and evenly conducted from the surface layer to the lower layer, and achieve pressure dispersion and support from the surface to the deep layer. At the same time, this design is effectively combined with the spring layer to avoid the "funnel effect" or "hammock effect" in the mattress structure.
