Description

Technical Field

[0001] The present invention relates to the technical field of household mattresses, and particularly to a spinal protection and pressure relief spring mattress. Background Art

[0002] With the continuous aggravation of the global population aging, the health and quality of life of the elderly have become the core issues of widespread social concern. After entering old age, the elderly inevitably experience degenerative changes in physical functions, including decreased muscle tension, increased bone loss, and limited joint mobility. Particularly importantly, due to osteoporosis, vertebral body deformation, and degenerative diseases, the spinal column and skeletal system of the elderly show greater vulnerability, resulting in a significant decline in the spinal support ability. Especially in the lumbar region, it is often difficult to maintain the normal physiological curve, thus causing health problems such as compressive pain and joint discomfort. Sleep, as an important link in maintaining life and health, is crucial for the rehabilitation and quality of life of the elderly. However, the above problems have significantly reduced their comfort and the proportion of deep sleep during sleep.

[0003] In addition, as the basal metabolic rate of the elderly decreases, their skin gradually becomes thinner, drier, and has a weakened adaptability to the external environment. This change not only makes the elderly more likely to feel cold in a low-temperature environment but also increases the risk of discomfort or even injury to the skin after being compressed or rubbed. Especially for the elderly with disabilities or limited mobility, maintaining the same sleeping position for a long time will cause continuous compression of local tissues, which is extremely likely to induce complications such as pressure sores. These problems indicate that providing mattress products with professional designs for the elderly, aiming to effectively support their bodies, protect the skin, and improve the sleep environment, is a difficult problem that urgently needs to be solved at present.

[0004] However, most of the current mattress products on the market are mainly targeted at ordinary consumers and generally adopt a general design, which cannot effectively meet the unique physiological and health needs of the elderly. Traditional mattresses have obvious deficiencies in spinal support, uniform pressure distribution, and temperature and humidity regulation performance, and often cannot provide an ideal sleep experience. More critically, the lack of professional optimization design for spinal health and pressure management may exacerbate the problems of the elderly's skeletal system and even affect their overall health status.

[0034] Next, please refer to Figure 1 and Figure 2 In the embodiments of the present invention, a spinal protection and pressure-relieving spring mattress is provided, including a bed perimeter edge 6. The bed perimeter edge 6 is sequentially provided with an adaptive spring mattress core 5, a multi-layer composite material padding layer, and a temperature control and adjustment fabric composite layer 1 from the inside to the outside;

[0035] Among them, the adaptive spring mattress core 5 includes multiple strands of double-segment composite special-shaped springs, and the multiple strands of double-segment composite special-shaped springs adopt a segmented stiffness design;

[0036] The multi-layer composite material padding layer includes a soft and warm heat preservation covering layer 2, a gentle and pressure-relieving layer 3, and a pressure-dividing support layer 4 from top to bottom in sequence;

[0037] The temperature control and adjustment fabric composite layer 1 is made of temperature control fabric C11.

[0038] The spinal protection and pressure relief spring mattress described in this embodiment can significantly improve the dynamic support performance and pressure dispersion ability of the mattress by integrating multiple multi-strand double-segment composite special-shaped springs and multi-layer composite material paving technology, thereby alleviating the burden on the spine and maintaining the natural curved spinal physiological structure. At the same time, by setting the temperature control and adjustment fabric composite layer 1 and the soft and warm heat preservation cover layer 2, the effect of dynamically adjusting the temperature and humidity of the sleep microenvironment can be achieved, so that the discomfort problems caused by cold or dryness can be further alleviated. In addition, the gentle design of the gentle pressure relief layer 3 combined with the application of antibacterial materials not only improves the skin friendliness of the mattress, but also effectively reduces the risk of skin friction and allergies. Thus, the spinal protection and pressure relief spring mattress has the characteristics of safety, comfort and functionality.

[0039] It should also be noted that the spinal protection and pressure relief spring mattress provided in this embodiment is particularly suitable for the elderly. This mattress can meet the special health needs of the elderly. From spinal support, pressure dispersion, temperature and humidity adjustment to skin protection, it comprehensively improves the sleep quality of the elderly and solves the problems of insufficient spinal health protection, uneven pressure distribution and poor adaptability to temperature and humidity environment in the general design of existing mattresses. Of course, the spinal protection and pressure relief spring mattress provided in this embodiment is also suitable for other people with similar sleep problems.

[0040] Combined with Figures 3 to 5 , in one embodiment, the adaptive spring bed core 5 is divided into a head support area, a torso support area and a leg support area, and the multiple multi-strand double-segment composite special-shaped springs have different elastic coefficients in the head support area, the torso support area and the leg support area.

[0041] Specifically, the multiple multi-strand double-segment composite special-shaped springs are encapsulated into a plurality of independent pocketed springs, and the plurality of independent pocketed springs are arranged according to a straight row pattern, and the plurality of independent pocketed springs are connected into an integral bed core structure.

[0042] The multiple multi-strand double-segment composite special-shaped springs include an upper segment spring and a lower segment spring. The upper segment spring is arranged in a drum-shaped structure, and the lower segment spring is arranged in a cone-shaped structure.

[0043] The number of spring coils of the upper segment spring is greater than that of the lower segment spring, and the flexibility of the upper segment spring is greater than that of the lower segment spring.

[0044] The elastic coefficient of the multiple multi-strand double-segment composite special-shaped springs in the head support area is 5-8 N / cm, in the torso support area is 10-15 N / cm, and in the leg support area is 6-10 N / cm.

[0045] In this embodiment, the core structure of the adaptive spring mattress core 5 is a multi-strand double-segment composite special-shaped spring. It adopts a segmented stiffness design and has dynamic response ability to achieve an organic combination of soft fitting and deep support, so as to provide users with a more accurate and scientific support experience. In addition, the multi-strand double-segment composite special-shaped spring adopts an independent pocketed form, and the stability of the spring is further enhanced through the multi-strand wire design to optimize the shock absorption frequency.

[0046] Specifically, the adaptive spring mattress core 5 adopts three-zone precise support, which is optimized according to the human body pressure distribution. That is, according to the pressure distribution characteristics of different parts of the human body, the mattress core is divided into a head support area, a torso support area, and a leg support area. As Figure 4 shown, Figure 4 in which R1, R2, and R3 respectively correspond to the head support area, the torso support area, and the leg support area. The elastic coefficient of each area is carefully designed to meet the specific support force requirements of different parts, so as to provide a more scientific and comfortable support experience. As Figure 3 shown, Figure 3 from left to right in the figure are the multi-strand double-segment composite special-shaped springs corresponding to the head support area, the torso support area, and the leg support area respectively. In addition, the adaptive spring mattress core 5 is composed of a number of multi-strand independent pocketed springs arranged according to the straight row pattern, and these independent pocketed springs are connected into an integral structure through high-strength glue or other fixing techniques to ensure the stability and durability of the mattress core. And each independent pocketed spring is composed of a multi-strand double-segment composite special-shaped spring wrapped in a non-woven bag.

[0047] Furthermore, the multi-strand double-segment composite special-shaped spring adopts a segmented structure design to achieve a gradient distribution of longitudinal stiffness. That is, the multi-strand double-segment composite special-shaped spring includes an upper spring and a lower spring. Among them, the upper spring adopts a drum-shaped structure (narrow at both ends and wide in the middle), with more turns and greater flexibility, and has excellent primary support characteristics. When a person applies pressure to the mattress, the upper drum-shaped spring is compressed first, which can accurately fit the body curve, especially in high-pressure areas such as the shoulders, back, and hips. Its soft primary support effectively disperses the pressure and reduces the pressure on key parts of the body, thus providing a comfortable "wrapping feeling". The lower spring adopts a conical design (narrow at the upper end and wide at the lower end), with fewer turns and stronger rigidity, and has excellent deep support performance. When the pressure gradually increases, the upper drum-shaped spring will be compressed to the saturation state, and then transfer the pressure to the lower conical spring. The conical spring can provide strong deep support to prevent the user's body from sinking too much during sleep. At the same time, the high rigidity of the lower spring ensures the overall structural stability of the mattress, can meet the needs of long-term use, and effectively prevent the occurrence of the "hammock effect" or "funnel effect".

[0048] Specifically, the elastic coefficient of the multi-strand double-segment composite special-shaped spring corresponding to the head support area is 5-8 N / cm (lower stiffness), and the proportion of the upper-segment drum-shaped spring is higher, making it easier for primary compression and conforming to the human body shape of the head and shoulders. The elastic coefficient of the multi-strand double-segment composite special-shaped spring corresponding to the torso support area is 10-15 N / cm (medium-high stiffness), and the rigidity and wire diameter of the lower-segment conical spring increase to enhance the anti-deformation ability, with an appropriate number of turns to enhance the dynamic response ability. The elastic coefficient of the multi-strand double-segment composite special-shaped spring corresponding to the leg support area is 6-10 N / cm (medium stiffness), and the lower-segment conical spring has appropriate rigidity to ensure the fit between the legs and the mattress.

[0049] In addition, as Figure 5 shown, the dynamic response ability is reflected in non-linear deformation and pressure adaptation. That is, the upper-segment drum-shaped spring compresses first under slight pressure to provide soft support; as the pressure increases, the lower-segment conical spring gradually takes over, forming a segmented dynamic response system. This non-linear deformation characteristic enables the mattress to automatically adapt according to the user's weight, posture, and pressure distribution, and both lightweight users and heavier users can obtain comfortable support.

[0050] Furthermore, the multi-strand 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 spring, the force will be dispersed to each steel wire instead of concentrating on a single steel wire. The deformation of each steel wire absorbs part of the vibration energy, making the overall structure respond softly to vibration, thereby reducing the vibration transmission efficiency. The slight sliding, friction, or torsion between the multi-strand steel wires further dissipates the vibration energy, achieving the shock absorption effect. The non-linear mechanical characteristics of the multi-strand spring endow it with the dynamic adaptation ability under different pressures. In the initial stage, the thinner strands or the outer steel wires, as the flexible part of the multi-strand spring, will deform preferentially to mitigate the vibration impact under light pressure. Under high pressure, as the pressure increases, the overall multi-strand structure gradually increases in rigidity, so as to be able to withstand greater vibration impacts. In this non-linear deformation process, the spring produces a segmented response of "buffering-absorbing-rebounding" to vibration, significantly reducing the intensity and frequency of vibration transmission.

[0051] In one embodiment, the soft and warm heat-insulating covering layer 2 sequentially includes a combination layer of superfine fiber and recycled polyester fiber, a combination layer of phase change microcapsule fiber and hollow fiber, and a combination layer of hollow fiber and wool from top to bottom.

[0052] The material of the soft and gentle pressure-relieving layer 3 includes at least two of new memory elastic foam, dynamic response fiber, latex, and high-elastic foam, and the hardness of the soft and gentle pressure-relieving layer 3 gradually increases from top to bottom.

[0053] The material of the pressure-dividing support layer 4 includes a highly elastic foam substrate, and the hardness of the pressure-dividing support layer 4 is greater than that of the soft and gentle pressure-relieving layer 3.

[0054] The multi-layer composite paving layer described in this embodiment adopts an overall multi-layer gradient stratification and dynamic adaptability design, which can solve the problems of "pressure fault" and "hanging feeling" of the traditional pressure-relieving 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. In addition, this structure also has functions such as moisture absorption and sweat discharge, anti-allergy, warmth retention and moisture retention. From top to bottom, it includes a soft and warm heat-preserving covering layer 2, a soft and gentle pressure-relieving layer 3, and a pressure-dividing support layer 4. Specifically:

[0055] (1) The soft and warm heat-preserving covering layer 2 realizes an all-round upgrade of softness, dynamic warmth retention and environmental adaptability through the ingenious combination of multi-layer composite and high-performance materials. Its total thickness is 1 cm - 1.5 cm, and the thickness of each layer is quite the same. The first layer of this layer (the soft and skin-friendly surface layer, that is, Figure 2 the soft and skin-friendly surface layer C21 in Figure 2 ) adopts a combination of ultra-fine fibers (50% - 70%) and recycled polyester fibers (30% - 50%) to provide a smooth and soft touch and increase durability. The target thickness is 3 - 5 mm, and the gram weight is 300 - 400 g / m²; the second layer (the middle layer for dynamic warmth retention, that is, Figure 2 the dynamic warmth-retention middle layer C22 in

[0056] ) adopts phase change microcapsule fibers (50% - 70%) and hollow fibers (30% - 50%) to achieve dynamic temperature control and warmth retention, lock in heat and reduce heat loss; the third layer (the bottom layer for high-efficiency heat insulation, that is, Figure 2As shown, the gentle pressure-relieving layer 3 from top to bottom successively includes a new memory elastic foam layer C31 and a high-elasticity foam layer C32. Here, the new memory elastic foam refers to a memory sponge that, in addition to polyurethane, may incorporate other types of polymers and additives, such as rubber, EVA (ethylene-vinyl acetate copolymer), and phase change materials. Dynamic response fibers are a type of highly adaptable material that can dynamically adjust according to environmental and body conditions. Their wide range of application fields and potential to enhance the wearing experience make them occupy an important position in modern textile technology. Dynamic response fibers are a special type of functional fiber that can dynamically adjust their properties according to changes in the external environment or body state. Such fibers are often used in fields such as clothing, sportswear, and medical devices, aiming to enhance comfort, elasticity, and functionality. The design principles of dynamic response fibers are mainly based on the following aspects: temperature regulation ability, moisture regulation, pressure and tension response, application of phase change materials, intelligent functions (such as monitoring heart rate, temperature, or motion state), etc. High-elasticity foams are foam materials with high resilience, such as high-elastic sponges and latex.

[0057] Compared with traditional rigid or single-elastic foam materials, the material combination used in this embodiment has a higher deformation ability, can disperse local pressure, and at the same time provides dynamic buffering and support according to the pressure changes in different parts of the human body, especially achieving precise fitting in the shoulder, waist, and hip regions, enhancing the "wrapping feeling".

[0058] (3) The pressure-dividing support layer 4 is composed of a high-elasticity foam substrate (such as high-elastic sponges and latex, which are foam materials with high resilience), with a thickness of 1 - 3 cm, used to provide deep support and avoid sagging. This layer and the gentle pressure-relieving layer 3 together constitute a soft-hard gradient layered design to solve the problems of "pressure fault" and "hanging feeling" of traditional pressure-relieving layers, ensuring that the pressure is evenly conducted from the surface layer to the lower layer and avoiding the occurrence of "funnel effect" and "hammock effect".

[0059] In one embodiment, the materials of the temperature control and regulation fabric composite layer 1 include a temperature control fabric C11, flexible fibers, skin-friendly foam, and non-woven fabric.

[0060] The temperature control and regulation fabric composite layer 1 is fixed by an independent pattern quilting process, and the pattern size is less than 5 inches.

[0061] The temperature control and regulation fabric composite layer 1 is woven by interlacing a phase change microcapsule yarn and a composite moisturizing fiber yarn, and the ratio of the phase change microcapsule yarn to the composite moisturizing fiber yarn is 2 - 4:6 - 8.

[0062] In this embodiment, combined with Figure 2, the temperature control and adjustment fabric composite layer 1 is composed of a temperature control fabric C11, a flexible fiber layer C12, a skin-friendly foam layer C13, and a non-woven fabric (located at the bottom layer of the temperature control and adjustment fabric composite layer 1), and is fixed by an independent pattern quilting process. The pattern size is less than 5 inches (12.7 cm) to ensure the stability and elasticity of the fabric composite layer. The temperature control and adjustment fabric layer is woven by interlacing phase change microcapsule yarns and composite moisturizing fiber yarns in proportion. Among them, the phase change microcapsule yarns are embedded with phase change materials to achieve the function of dynamic temperature adjustment. The phase change materials can be paraffin wax, fatty acids, inorganic salt hydrates, or bio-based phase change materials (Bio-based PCMs), etc. The embedding ratio of the phase change materials can be 5% to 30% of the phase change microcapsule yarns. A higher addition ratio can increase the temperature control ability, but may affect the softness and breathability of the yarns. After adding the phase change materials, the phase change materials are encapsulated through a chemical process to form microcapsules. These microcapsules can be mixed with other fibers (such as polyester, nylon, etc.) to enable the phase change materials to be stably embedded in the yarns. The phase change materials (such as microcapsule phase change materials) can also be mixed with matrix fibers such as polyester fibers, and then made into yarns through a spinning process. This method is simple and effective, but the phase change materials may hydrolyze due to fiber moisture absorption. In addition, the proportion of the phase change microcapsule yarns is between 20% and 40%. This is because a higher proportion of the phase change microcapsule yarns can improve the effect of temperature control and adjustment, but at the same time, the breathability and softness of the fabric need to be considered. The proportion of the composite moisturizing fiber yarns is between 60% and 80%. In this way, the composite moisturizing fiber yarns can provide good comfort and breathability.

[0063] The temperature control and adjustment fabric composite layer 1 described in this embodiment can automatically adjust the surface temperature of the mattress according to the environmental temperature change, helping the elderly to maintain a suitable sleep microenvironment in different seasons and alleviating the impact of cold or heat on sleep. In addition, composite moisturizing fibers (such as TENCEL TM - a regenerated fiber made from wood pulp, a high-performance polyester fiber, Bamboo Fiber - bamboo fiber, etc.) have good hydrophilicity, can keep the skin moist, and relieve the discomfort caused by dryness, which is particularly suitable for the needs of elderly sensitive skin care. The flexible fibers can be selected from one or more of polyester fibers, viscose fibers, microfibers, and Lycra fibers. It is preferred to choose a combination of 30%-50% polyester fibers and 50%-70% viscose fibers, or a combination of 50% polyester fibers and 50% microfibers. The skin-friendly foam can be selected from one or more of polyurethane viscoelastic flexible foams, latex foams, or bio-based foam materials. It is preferred to choose a combination of hydrophilic sponges and flexible polyurethane sponges. The thickness of the temperature control and adjustment fabric composite layer 1 is recommended to be between 2 cm and 5 cm.

[0064] Generally speaking, the spinal care and decompression spring mattress provided in this embodiment has the following beneficial effects:

[0065] (1) Based on the design of multi-strand double-segment composite special-shaped springs, the mattress has non-linear deformation characteristics and the dynamic response ability of the support performance. During the pressure-bearing process, the upper drum-shaped springs first compress due to their structural characteristics, so they can provide a gentle buffer, conform to the subtle curves of the body, provide a soft support effect, and effectively avoid local high pressure on the body. When the pressure gradually increases, the upper drum-shaped springs enter the compression saturation state, and the pressure is transmitted to the lower conical springs, 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. At the same time, the multi-strand springs effectively reduce the intensity and frequency of vibration transmission through dispersing vibration energy, non-linear deformation, multi-frequency absorption and internal damping effects, and have a significant shock absorption effect. Its unique mechanical characteristics and stability make it an ideal choice in elastic shock absorption devices.

[0066] (2) Based on the double-layer pressure-sharing structure design of the soft pressure-relieving layer 3 and the pressure-sharing support layer 4, combined with the multi-strand double-segment composite special-shaped springs, through a reasonable structure and hardness gradient distribution design, uniform and progressive pressure relief and transmission are achieved, avoiding the "pressure fault" and "weightlessness" body sensations caused by unreasonable mattress structure and hardness design. The soft pressure-relieving layer 3 can effectively conform to the human body curve and disperse the contact pressure through the high deformation characteristics of the material, providing sufficient "wrapping feeling" for the elderly, reducing the irritation and compression of the high-pressure points on the skin; the pressure-sharing support layer 4 further undertakes the support task, evenly transmitting the remaining pressure to the spring core of the bed, maintaining uniform support, and at the same time avoiding excessive deformation or sinking, and avoiding the "hammock effect" or "funnel effect".

[0067] (3) Through the double-layer pressure-sharing structure design of the soft pressure-relieving layer 3 and the pressure-sharing support layer 4, combined with the multi-strand double-segment composite special-shaped springs, the three work together to form a mechanical transmission and support system from the surface fitting to the bottom layer stable support, effectively reducing the burden on the spine and providing a stable support guarantee for maintaining the natural curvature of the spine.

[0068] (4) By regulating the synergistic effect of the fabric composite layer 1 and the soft and warm insulation covering layer 2 through temperature control, the dynamic temperature control, moisture protection and high-efficiency heat preservation functions of the mattress under different environmental conditions are realized. The temperature control regulating fabric composite layer 1 is woven by interlacing phase change microcapsule yarns and composite hydrophilic fiber yarns in a certain proportion, and realizes the dynamic balance of heat storage and release through phase change materials; it can automatically adjust the temperature of the mattress surface when the temperature changes, helping the elderly maintain a suitable sleep microenvironment and effectively alleviating problems such as joint stiffness and poor blood circulation caused by cold. At the same time, the composite hydrophilic fiber yarns have hydrophilic properties, keep the skin moist, and reduce the risks of dryness and allergy. The soft and warm insulation covering layer 2 further enhances the heat preservation performance of the mattress by effectively preventing heat loss in a cold environment through high-efficiency heat preservation design.
