Description

Technical Field

[0001] This utility model relates to the field of bed net technology, and in particular to a bed net with a variable stiffness spring. Background Technology

[0002] As people's living standards continue to improve, their demands for sleep quality are also increasing. As a crucial component of sleep, the performance and comfort of the bed have become a key focus for consumers. The mattress mesh, as one of the core components of the bed, directly affects the overall performance of the mattress and the user's sleep experience.

[0003] Currently, the mainstream spring mattress cores on the market are mainly individually pocketed springs and Bonnell springs. Individually pocketed springs are basically drum-shaped, with a small opening diameter and a large core diameter, forming a symmetrical structure around the core diameter. Bonnell springs are biconical, with a large opening diameter and a small core diameter, also forming a symmetrical structure around the core diameter. However, both types of springs only have one stiffness, resulting in a monotonous sleeping experience and a lack of depth. In actual use, they cannot simultaneously meet people's needs for a mattress that both softly embraces the body and provides stable support.

[0004] Therefore, it is necessary to develop a bed net that can achieve variable stiffness and precise zoned support. Utility Model Content

[0005] This utility model provides a bed net with a variable stiffness spring to solve the problems in the prior art.

[0006] The present invention adopts the following technical solution: a bed net with variable stiffness springs, which is composed of a head area, a back area, a waist area, a hip area, and a leg area connected in sequence; the bed net further includes: a first spring, of which a plurality of springs are arranged evenly to form the head area, back area, and leg area of ​​the bed net; a second spring, of which a plurality of springs are arranged evenly to form the waist area of ​​the bed net; and a third spring, of which a plurality of springs are arranged evenly to form the hip area of ​​the bed net; the first spring, the second spring, and the third spring each include a stable support area and a soft support area located above the stable support area; wherein the total number of coils of the second spring, the first spring, and the third spring are equal, and the number of coils of the soft support area gradually increases. Since the total number of coils of the second, first, and third springs is equal, and the number of coils in the soft support area gradually increases, the support and wrapping performance of the three types of springs are also different. Different springs are used in the head, back, waist, hip, and leg areas to achieve precise zoned support, better adapt to the weight distribution and curves of the human body, and further improve the support effect and comfort.

[0007] Preferably, each of the first spring, the second spring, and the third spring is placed in an individual bag to form an individually bagged spring.

[0008] Preferably, the coil diameters of the several spring coils in the stable support area are equal, while the coil diameters of the several spring coils in the flexible support area increase sequentially from top to bottom, and are all greater than or equal to the coil diameters of the several spring coils in the stable support area. This gradual change in coil diameter in the flexible support area allows the springs to better adapt to the contours and pressure changes of different parts of the human body when compressed.

[0009] Preferably, the diameter difference between any two adjacent spring coils in the flexible support area is at least 4 mm. As the pressure increases, the spring coils in the flexible support area deform sequentially. The difference in coil diameter allows them to compress and rebound in an orderly manner, ensuring the flexibility and recoverability of the spring throughout the entire working process.

[0010] Preferably, the pitch of the flexible support area increases sequentially from top to bottom.

[0011] Preferably, the lowest spring coil in the stabilizing support area is a support coil. The pitch between this support coil and its adjacent spring coils is less than the minimum pitch of the flexible support area. The pitches of the remaining spring coils in the stabilizing support area are equal and greater than the maximum pitch of the flexible support area. When the flexible support area is fully compressed and tightened, the stabilizing support area plays a major supporting role. The fact that the pitches of the remaining spring coils in the stabilizing support area, except for the support coil, are equal and greater than the maximum pitch of the flexible support area allows the spring coils to provide a more stable and consistent supporting force when subjected to stress.

[0012] Preferably, the first, second, and third springs each have 10 coils. The first spring has a wire diameter of 2.0mm, with its soft support area consisting of the first 5 coils and its stable support area consisting of the last 5 coils. The second spring has a wire diameter of 2.2mm, with its soft support area consisting of the first 4 coils and its stable support area consisting of the last 6 coils. The third spring has a wire diameter of 2.2mm, with its soft support area consisting of the first 6 coils and its stable support area consisting of the last 4 coils. The third spring in the hip area has a larger soft support area, providing more gentle support, allowing the hip area to sink effectively, while the lumbar area receives effective support, allowing the spine to more closely follow its natural curvature when lying on the mattress.

[0013] Preferably, the length of the head region is configured to be 280mm, the length of the back region is configured to be 360mm, the length of the waist region is configured to be 120mm, the length of the hip region is configured to be 480mm, and the length of the leg region is configured to be 760mm.

[0014] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0015] Firstly, the mattress is divided into five zones: head, back, legs, waist, and hips, each composed of a first, second, and third spring evenly arranged. Different springs are configured for different zones according to the pressure requirements of different parts of the body, adapting to the body's curves and weight distribution. Each spring has a stable support zone and a soft support zone, with the soft support zone having lower stiffness and the stable support zone having higher stiffness. When a person lies on the mattress, the body parts first apply pressure to the soft support zone of the spring, causing it to deform significantly and conform well to the body. As the pressure increases, the soft support zone is fully compressed and tightened, and only then does the spring in the stable support zone deform significantly, providing stable support.

[0016] Secondly, mainstream spring mattress cores on the market offer a limited sleeping experience, while this mattress uses variable stiffness springs to combine soft envelopment with stable support, creating a layered sleeping experience that better meets people's sleep needs for mattresses.

[0017] Thirdly, because the upper layer of springs is softer, different parts of the body can better conform to the mattress, reducing pressure on the body-bed contact surface, avoiding excessive local pressure, lowering the risk of bedsores, and improving sleep comfort. The lower layer of springs is firmer, which can prevent excessive sinking in the buttocks area, avoiding spinal curvature and deformation caused by buttocks sinking, helping to maintain the normal physiological curve of the spine and protecting spinal health.

[0018] Fourth, since the total number of coils of the second, first, and third springs is equal, and the number of coils in the soft support area gradually increases, the support and wrapping performance of the three springs (i.e., the first, second, and third springs) are also different. Different springs are used in the head, back, waist, hip, and leg areas to take into account the characteristics of different parts of the human body, so as to achieve precise zoned support, better adapt to the weight distribution and curves of the human body, and further improve the support effect and comfort.

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1 to 2 As shown, this utility model embodiment provides a bed net with variable stiffness springs, which is composed of a head area, a back area, a waist area, a hip area and a leg area connected in sequence; the bed net also includes three different types of springs: a first spring, a second spring and a third spring; in practical applications, each of the first spring, the second spring and the third spring is put into an independent pocket to form an independent pocket spring.

[0026] Several first springs are evenly arranged to form the head, back, and leg areas of the mattress; several second springs are evenly arranged to form the waist area of ​​the mattress; and several third springs are evenly arranged to form the hip area of ​​the mattress. Each of the first, second, and third springs includes a stable support area 2 and a flexible support area 1 located above the stable support area 2. The total number of coils in the second, first, and third springs is equal, and the number of coils in the flexible support area 1 gradually increases. Figure 1 and Figure 2 The image shows the structure of the first spring. Figure 2 The first spring on the left in the diagram is a schematic diagram of its compressed state. Figure 2 The first spring on the right is shown in its extended state.

[0027] The mattress is divided into five zones: head, back, legs, waist, and hips, each composed of a first, second, and third spring evenly arranged. Different springs are configured for different zones according to the pressure requirements of different parts of the body, adapting to the body's curves and weight distribution. Each spring has a stable support zone 2 and a soft support zone 1, with the soft support zone 1 having lower stiffness and the stable support zone 2 having higher stiffness. When a person lies on the mattress, the body parts first apply pressure to the soft support zone 1, causing it to deform significantly and conform well to the body. As the pressure increases, the soft support zone 1 is fully compressed and tightened, at which point the spring in the stable support zone 2 undergoes greater deformation, providing stable support.

[0028] While most mainstream spring mattress cores offer a limited range of sleeping experiences, this mattress uses variable stiffness springs to combine soft comfort with stable support, creating a layered sleeping experience that better meets people's sleep needs.

[0029] Because the upper layer of springs is softer, different parts of the body can better conform to the mattress, reducing pressure on the body-bed contact surface, avoiding excessive local pressure, lowering the risk of bedsores, and improving sleep comfort. The lower layer of springs is firmer, preventing excessive sagging in the buttocks area, avoiding spinal curvature caused by buttock sagging, helping to maintain the normal physiological curve of the spine, and protecting spinal health.

[0030] In addition, since the total number of coils of the second spring, the first spring, and the third spring are equal, and the number of coils in the soft support area 1 gradually increases, the support and wrapping performance of the three springs (i.e., the first spring, the second spring, and the third spring) are also different. Different springs are used in the head, back, waist, hip, and leg areas to achieve precise zoned support, better adapt to the weight distribution and curves of the human body, and further improve the support effect and comfort.

[0031] In some practical applications, the coil diameters of the several spring coils 3 in the stable support area 2 are equal, while the coil diameters of the several spring coils 3 in the soft support area 1 increase sequentially from top to bottom, and are all greater than or equal to the coil diameters of the several spring coils 3 in the stable support area 2. The spring coil 3 with the smallest diameter at the top of the soft support area 1 deforms first under pressure. As the pressure increases, the spring coils 3 with gradually increasing diameters participate in the deformation in turn, making the deformation process of the soft support area 1 more gradual and continuous, and better conforming to the contours of the human body. When the soft support area 1 is fully compressed and tightened, the spring coils 3 with the same diameter in the stable support area 2 begin to work, providing stable and uniform support force due to their structural characteristics. The gradual change in coil diameter in the soft support area 1 allows the springs to better adapt to the contours and pressure changes of different parts of the human body when compressed, further enhancing the fit between the mattress and the human body and improving sleep comfort.

[0032] In some practical applications, based on the above embodiments, the pitch of the flexible support region 1 increases sequentially from top to bottom. Furthermore, the lowermost spring coil 3 of the stable support region 2 is a support coil 4, and the pitch between the support coil 4 and the adjacent spring coil 3 is less than the minimum pitch of the flexible support region 1. The pitches between the remaining spring coils 3 of the stable support region 2 are equal and greater than the maximum pitch of the flexible support region 1.

[0033] When a person lies on the mattress, the spring coil 3 with the smallest pitch at the top of the soft support area 1 is stressed first. Due to its small pitch, the spring coils 3 are relatively dense, making them easier to deform and quickly conform to the body surface. As the pressure is transmitted downwards, the pitch gradually increases, and the deformation capacity of the spring coils 3 changes gradually, allowing the soft support area 1 to deform in a gradual, continuous manner that better conforms to the body's pressure distribution, thus better wrapping the body. Once the soft support area 1 is fully compressed and tightened, the stable support area 2 plays its main supporting role. Except for the support coil 4, the remaining spring coils 3 in the stable support area 2 have equal pitches and are larger than the maximum pitch of the soft support area 1. This larger and more uniform pitch allows the spring coils 3 to provide more stable and consistent support force when stressed. The pitch between the support coil 4 and the adjacent spring coil 3 is smaller than the minimum pitch of the soft support area 1, which allows the support coil 4 to transmit pressure more stably when in contact with the mattress support structure (such as the bed frame), enhancing the overall stability of the mattress.

[0034] In some practical applications, the diameter difference between any two adjacent spring coils 3 in the flexible support area 1 is at least 4 mm. Because of this difference in diameter, the spring coils 3 in the flexible support area 1 will not jam due to their similar diameters when compressed. As the pressure increases, the spring coils 3 in the flexible support area 1 deform sequentially. The difference in diameter allows them to compress and rebound in an orderly manner, ensuring the flexibility and recoverability of the spring throughout its operation.

[0035] In summary, based on the above embodiments, in practical applications, the first, second, and third springs are all configured with 10 turns each. Specifically, the first spring has a wire diameter of 2.0 mm, its flexible support area 1 comprises the first 5 turns, and its stable support area 2 comprises the last 5 turns. The second spring has a wire diameter of 2.2 mm, its flexible support area 1 comprises the first 4 turns, and its stable support area 2 comprises the last 6 turns. The third spring has a wire diameter of 2.2 mm, its flexible support area 1 comprises the first 6 turns, and its stable support area 2 comprises the last 4 turns.

[0036] In some practical applications, based on the above embodiments, the soft support area 1 of the third spring is configured as the first 6 coils of the third spring, and the stable support area 2 of the third spring is configured as the last 4 coils of the third spring. The length of the head area of ​​the mesh bed is configured as 280mm, the back area as 360mm, the lumbar area as 120mm, the hip area as 480mm, and the leg area as 760mm. Therefore, the soft support area 1 of the third spring in the hip area is larger, providing softer support, allowing the hip area to sink effectively, while the lumbar area is effectively supported, so that when a person lies on the mattress, the spine is closer to its natural curvature.

[0037] Furthermore, the soft support area of ​​the first spring is configured as the first 5 coils of the first spring, wherein the diameter of the first coil is 45-50mm, the diameter of the second coil is 50-55mm, the diameter of the third coil is 55-60mm, the diameter of the fourth coil is 60-65mm, and the diameter of the fifth coil is 65-70mm; the stabilizing support area 2 of the first spring is configured as the last 5 coils of the first spring, each coil having an equal diameter of 55-60mm. The pitch of the first 5 coils of the first spring is 10-25mm, and the pitch of each coil gradually increases; the lowest spring coil 3 in the stabilizing support area 2 of the first spring is a support coil 4, and the pitch between the support coil 4 and the adjacent spring coil 3 is 5-10mm. The pitch between the remaining spring coils 3 in the stabilizing support area 2 is equal and 30-60mm.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
