Description

Technical Field

[0001] The utility model belongs to the technical field of mattresses, in particular to a three-zone waist-supporting and spine-protecting spring bed net. Background Art

[0002] The spring core of the mainstream spring mattress on the market is basically Bonnier spring net or independent coil pocket spring net. Bonnier spring has the advantages of strong elasticity and good support performance, but since each spring of Bonnier spring is connected in series by steel wire, each individual spring will interfere with each other when in use. Independent coil pocket spring net has good anti-interference performance because each spring is independently stressed and supported, but its spring structure support performance is not as strong as Bonnier spring.

[0003] For example, a hybrid three-zone bed net disclosed in Chinese patent CN213097143U includes a bed net body, wherein the bed net body includes a soft zone and a support zone along its length direction, wherein the soft zone is provided with two blocks, and the support zone is located between the two soft zones; the soft zone includes a plurality of independent pocket springs arranged in a matrix, and the support zone includes a plurality of Bonnier springs that are closely arranged and interconnected to form a net. By arranging the soft zones composed of independent pocket springs at both ends of the mattress, a softer and more comfortable use experience is provided while the support zone supports the human body;

[0004] However, in the above-mentioned prior art, different support strengths can be given to the user's waist and back, head and shoulders, and legs, with the waist and back being supported mainly with stronger strength, while the head and shoulders and legs are supported with soft strength. As a result, the user's overall posture is presented as a posture with the waist raised or tilted upward, which is not ergonomic and affects the user's lying comfort. Utility Model Content

[0005] The embodiment of the utility model provides a three-zone waist-supporting and spine-protecting spring bed net to solve the problems in the prior art.

[0006] The embodiment of the utility model adopts the following technical solution: a three-zone lumbar support and spine protection spring bed net, comprising a bed net body, the bed net body comprising strong support areas and soft support areas alternately arranged along its length direction, the strong support areas are configured into two groups and are respectively located on both sides of the soft support area;

[0007] The strong support area is a first spring group arranged along the length direction of the bed net body, and the spring coils in the first spring group have a large diameter and are loosely arranged. The soft support area is a second spring group arranged along the length direction of the bed net body, and the spring coils in the second spring group have a small diameter and are tightly arranged. The spring coil diameter of the first spring group is larger than the spring coil diameter of the second spring group, and the spring arrangement density of the first spring group is smaller than the spring arrangement density of the second spring group. The spring coil diameter of the second spring group in the middle soft support area is smaller, and the springs are arranged more tightly to achieve tighter and softer support for the waist and hip area. The spring coil diameter of the first spring groups at both ends is larger and is arranged more loosely, so as to achieve better support for the head, shoulders and leg areas.

[0008] Preferably, the first spring group is a plurality of Bonnier springs arranged in a rectangle, and the second spring group is a plurality of independent bagged springs arranged in a rectangle; the Bonnier springs have the characteristics of strong elasticity, excellent vertical support performance, and relatively high hardness, and the independent bagged springs are each independent and subjected to force individually, so the independent bagged springs can better conform to the curves of the human body, and support is provided by different degrees of expansion and contraction of each independent bagged spring, thereby achieving a uniform support effect.

[0009] Preferably, the steel wire diameter of the Bonnier spring is 2.2-2.3mm, the caliber is 68-73mm, and the core diameter is 35-38mm; the wire diameter of the independent pocket spring is 1.7-2.2mm, the caliber is 50-55mm, and the core diameter is 62-67mm. Using springs of appropriate models and sizes can be used to adapt to the corresponding soft support areas and strong support areas to meet the support requirements of different parts of the human body.

[0010] Preferably, the soft support area is located in the range of 660-1320mm along the length direction of the bed net body, and the two groups of strong support areas are respectively located in the range of 0-660mm and 1320-1980mm along the length direction of the bed net body. This size zoning configuration can meet the usage needs of most people.

[0011] Preferably, the height of the independent pocket springs in the soft support area is 1-3 cm higher than the Bonnier springs in the strong support areas at both ends.

[0012] Preferably, the connection between the soft support area and the two groups of strong support areas is set to be "S"-shaped along the width direction of the bed net body; when the human body is in a lying position, the independent bagged springs will be compressed in the waist and hip area first, feeling comfortable and soft, and then the shoulder and back area and leg area of ​​the human body will be supported by the Bonnier springs at both ends, so as to better and more accurately support the user's whole body area point to point.

[0013] Preferably, the bed net body is reinforced by frame edge steel wires on all sides, and the frame edge steel wires have two groups, upper and lower, and are respectively located on the upper and lower sides of the bed net body to ensure the overall stability of the bed net body.

[0014] Preferably, the independent pocket springs in the soft support area and the Bonnier springs in the strong support areas at both ends are fixedly connected by C-type nails, which can ensure the user's usage experience.

[0015] At least one of the above technical solutions adopted in the embodiment of the utility model can achieve the following beneficial effects:

[0016] Firstly, in the present invention, the spring coil diameter of the second spring group in the middle soft support area is smaller, and the springs are arranged more closely, so as to achieve a tighter and softer support for the waist and hip area, while the spring coil diameter of the first spring groups at both ends is larger and the arrangement is looser, so as to achieve better support for the head, shoulders and leg areas.

[0017] Secondly, in the spring bed net main body of the utility model, the surface hardness of the Bonnier spring area is relatively soft, and the core layer and the bottom layer are relatively hard. Therefore, when lying on the side, it can be ensured that the shoulders of the human body have a certain amount of sinking without excessive sinking; the surface hardness, core layer hardness and bottom layer hardness of the independent pocket spring area are relatively hard, so the support for the waist and buttocks is better; in terms of the overall hardness of the spring bed net main body, the independent pocket spring area is softer than the Bonnier spring area, so the waist and buttocks will have enough sinking when lying flat, and at the same time, the independent pocket spring has an independent supporting effect, the support of the waist and buttocks is more delicate, and the spine is guaranteed to be in a naturally curved state.

[0018] Third, when the human body turns over in bed, it mainly relies on the coordinated movements of the waist, hips and torso. The use of independent pocket springs at the waist and hips can provide better stability and anti-interference, effectively enhance the sense of stability when turning over, and the independent pocket springs have better resilience and fatigue resistance. The use of independent pocket springs in the waist and hip area can effectively extend the service life of the mattress and avoid collapse in the waist and hip area due to long-term use of the mattress.

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Reference Figures 1 to 5 As shown, the embodiment of the utility model provides a three-zone waist support and spine protection spring bed net, including a bed net body 1, the bed net body 1 includes a strong support area 11 and a soft support area 12 alternately arranged along its length direction, the strong support area 11 is configured into two groups and is respectively located on both sides of the soft support area 12, and a total of three groups of strong support areas 11 and soft support areas 12 are arranged, and the number ratio of strong support areas 11 to soft support areas 12 is 2:1, that is, the soft support area 12 is located in the middle of the bed net body 1, and the strong support areas 11 are located at both ends of the bed net body 1. The soft support area 12 mainly supports the waist and hip area of ​​the user, and the strong support areas 11 at both ends mainly support the head, shoulders and leg areas of the user;

[0030] The strong support area 11 is a first spring group 111 arranged along the length direction of the bed net body 1, and the spring coils in the first spring group 111 have a large diameter and are arranged loosely. The soft support area 12 is a second spring group 121 arranged along the length direction of the bed net body 1, and the spring coils in the second spring group 121 have a small diameter and are arranged tightly. The spring coil diameter of the first spring group 111 is larger than the spring coil diameter of the second spring group 121, and the spring arrangement density of the first spring group 111 is smaller than the spring arrangement density of the second spring group 121. Therefore, the spring coil diameter of the second spring group 111 in the middle soft support area 12 is smaller, and the springs are arranged more tightly, so as to achieve a tighter and softer support for the waist and hip area. The spring coil diameters of the first spring groups 121 at both ends are larger and are arranged more loosely, so as to achieve better support for the head, shoulders and leg areas.

[0031] Embodiment 1:

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the first spring group 111 is a plurality of rectangularly arranged Bonnier springs 112. The Bonnier spring 112 is a spring with large upper and lower port diameters, a small middle diameter, and end face knotted winding molding. It has the characteristics of strong elasticity, excellent vertical support performance, and relatively high hardness.

[0033] The second spring group 121 is a plurality of independent pocket springs 122 arranged in a rectangular shape. Each spring in the independent pocket spring 122 is independently packed into a bag, so the springs are independent and independently stressed. A part of the spring that is squeezed and stretched does not affect the unsqueezed springs next to it. Therefore, the spring that is independently stressed produces an effect of no interference when lying down and sleeping, greatly reducing the impact of the user's actions such as turning over and getting up at night on the sleeping partner. Because the springs are independent and stressed individually, the independent pocket springs 122 can better conform to the curve of the human body, and support through the different degrees of expansion and contraction of each spring, thereby achieving a uniform support effect.

[0034] The spring particles of the strong support area 11 composed of the two-end Bonnier springs 112 are connected by spiral steel wires, and the spring particles of the soft support area 12 composed of the independent pocket springs 122 are glued together. This connection method can make the independent pocket springs 122 closer, reduce the friction and noise between the independent pocket springs 122, and improve the comfort and stability of the mattress;

[0035] The bed net body 1 is reinforced by frame edge steel wires 2 on all sides. The frame edge steel wires 2 have two groups, upper and lower, and are respectively located on the upper and lower sides of the bed net body 1 to ensure the overall stability of the bed net body 1.

[0036] The independent pocket springs 122 of the soft support area 12 and the Bonnier springs 112 of the strong support areas 11 at both ends are fixedly connected by C-type nails (C-type nails are prior art and not shown in the figure), which can give the connections between different partitions a certain connection stability and avoid the different partitions from being fractured after being subjected to pressure and presenting excessive height differences, affecting the user experience.

[0037] In the spring bed net body 1, the surface hardness of the Bonnier spring 112 area is relatively soft, and the core layer and bottom layer are relatively hard, so when lying on the side, it can ensure that the shoulders of the human body have a certain amount of sinking without excessive sinking; the surface hardness, core layer hardness and bottom layer hardness of the independent pocket spring 122 area are relatively hard, so the support for the waist and buttocks is better;

[0038] In terms of the overall hardness of the spring bed net body 1, the independent pocket spring 122 area is softer than the Bonnier spring 112 area, so the waist and hips will have enough sinking when lying flat. At the same time, the independent pocket spring 122 has an independent supporting effect, and the support for the waist and hips is more delicate, ensuring that the spine is in a naturally curved state.

[0039] In addition, when the human body turns over in bed, it mainly relies on the coordinated movements of the waist, hips and torso. The use of independent pocket springs 122 at the waist and hips can provide better stability and anti-interference, effectively enhance the sense of stability when turning over, and the independent pocket springs 122 have better resilience and fatigue resistance. The use of independent pocket springs 122 in the waist and hip area can effectively extend the service life of the mattress and avoid collapse in the waist and hip area of ​​the mattress due to long-term use.

[0040] Specifically, the steel wire diameter of the Bonnier spring 112 is 2.2-2.3mm, the caliber is 68-73mm, and the core diameter is 35-38mm; the wire diameter of the independent pocket spring 122 is 1.7-2.2mm, the caliber is 50-55mm, and the core diameter is 62-67mm. Using springs of appropriate models and sizes can be used to adapt to the corresponding soft support area 12 and strong support area 11 to meet the support requirements of different parts of the human body.

[0041] Specifically, the soft support area 12 is located in the range of 660-1320mm along the length direction of the bed net main body 1, which is the waist and hip support area; the two groups of strong support areas 11 are respectively located in the range of 0-660mm and 1320-1980mm along the length direction of the bed net main body 1, which are the head and shoulder or leg support areas respectively. This size zoning configuration can meet the usage needs of most people.

[0042] Embodiment 2:

[0043] The height of the independent bagged spring 122 in the soft support area 12 is 1-3 cm higher than the Bonnier spring 112 in the strong support areas 11 at both ends. On the basis of the above-mentioned embodiment one, the height of the independent bagged spring 122 can be 2 cm higher than the Bonnier spring 112 as the best. Since the waist and hip area of ​​the human body is the area with the largest weight, when the human body is in a lying position, the waist and hip area will first compress the independent bagged spring 122 to feel comfortable and soft, and then the shoulder and back area and the leg area of ​​the human body will be supported by the Bonnier springs 112 at both ends, so as to better and more accurately support the user's whole body area point to point, sensitively capture the waist and hip area curve to be more in line with the natural curve of the human body, and also ensure the use of a large number of people.

[0044] Embodiment three:

[0045] like Figure 1 and Figure 5 As shown, in some practical applications, the above two embodiments can be combined, and the connection between the soft support area 12 and the two groups of strong support areas 11 can be set to an "S" shape along the width direction of the bed net body 1, so that the soft support area 12 is presented in different positions along the length direction of the bed net body 1. In this case, the use needs of people of different heights can be met (for example, the heights of husband and wife are different, and the use of this S-shaped setting can make the bed net body 1 have good and comfortable support for both husband and wife).

[0046] Test report on various data of bed net main body 1:

[0047] According to the group standards T / SZFA2003.1-2019 "Mattress Ergonomics Evaluation - Mattress Hardness Grading and Distribution Test and Evaluation Method" and T / SZFA2003.2-2019 "Mattress Ergonomics Evaluation - Mattress Fit Quantification and Evaluation Method", the overall hardness of the mattress, the hardness of each layer of the mattress, and the hysteresis loss rate are measured.

[0048] The hardness of each layer and the total hardness of the spring bed net are the average values ​​of the hardness of each layer and the total hardness of each test point. The hardness of each layer of the spring bed net refers to the hardness index of the surface layer, core layer and bottom layer. The larger the index value, the softer the layers are. The total hardness is the sum of the hardness of each layer. The hardness grade is an objective indicator for evaluating the overall hardness of the mattress, ranging from 1 to 10. The larger the value, the softer the mattress. The hysteresis loss rate is the ratio of the displacement of the spring bed net during loading and unloading to the area enclosed by the load. The surface hardness of the spring bed net is the displacement value corresponding to 40N minus the displacement value corresponding to 4N, the core hardness is the displacement value corresponding to 200N minus the displacement value corresponding to 40N, and the bottom hardness is the displacement value corresponding to 250N minus the displacement value corresponding to 200N. The total hardness value is the sum of the three hardness index values.

[0049] ①Hardness grade calculation

[0050] The calculation formula for the average value T of the slope of the spring bed net loading curve is as follows:

[0051]

[0052] Wherein: T is the average value of the slope of the loading curve, in Newton per millimeter (N / mm); T 210 is the tangent slope of the loading curve at 210N, in Newton per millimeter (N / mm); T 275 is the tangent slope of the loading curve at 275N, in Newton per millimeter (N / mm); T 340 is the tangent slope of the loading curve at 340N, in Newton per millimeter (N / mm).

[0053] K is an important factor affecting the hardness of the bed net, and its unit is mm 2 , the formula is as follows:

[0054]

[0055] Where K is the factor affecting the hardness of the bed net, and the unit is square millimeter (mm 2 ), A450 is the total area between the loading curve and the x-axis in the range of 0N-450N, in Newton millimeters (N mm); T is the average value of the slope of the loading curve, in Newton per millimeter (N / mm).

[0056] The calculation formula for the hardness grade S of the spring bed net is as follows:

[0057] S=10(1-e-(Ka+b))2

[0058] S is the hardness grade of the spring bed net; K is an important factor affecting the hardness of the spring bed net, and the unit is square millimeter (mm 2). a is 6.47×10 -3; b is -0.91467; e is a natural constant. 1≤S≤10, the smaller the S value, the harder it is; when S<3 means hard, 3≤S≤6 means moderate hardness, and 6<S≤10 means soft. Each test point is tested once, and the hardness grade of the spring bed net is the average of the hardness grades of each test point.

[0059] Spring bed net rebound and stability test method. This test is in accordance with GBT 6670-2008 "Determination of rebound properties of soft foam polymer materials by falling ball method". The main principle is: use a steel ball with a certain mass and diameter to drop from a fixed height to the surface of the sample, measure the height of the steel ball bounce, and calculate the percentage of the ratio of the steel ball bounce height to the drop height.

[0060] Table 1 Spring bed net hardness index

[0061]

[0062] The waist and hip parts (independent pocket spring 122 (wire diameter 2.2) area) of the spring bed net body 1 are relatively soft, while the head, shoulders and legs are relatively hard. At the same time, the waist and hip parts are designed with independent pocket springs 122, which have good independent support performance. On the one hand, it is conducive to sufficient sinking of the buttocks to ensure that the spine is in a natural curved state, and on the other hand, it can prevent excessive sinking of the buttocks, which is conducive to avoiding the funnel effect.

[0063] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
