Description

Technical Field

[0001] The utility model relates to the technical field of spring mattresses, in particular to an independent spring structure, a bed net and a mattress which can be disassembled, assembled and customized. Background Art

[0002] Independent springs are packed in non-woven fabric bags and then sealed by gluing or ultrasonic bonding. The more turns a spring has, the higher the spring body is and the softer it is. The most turns are 6 or 7. The number of springs arranged is based on the inner diameter of the spring. The smaller the inner diameter, the more springs are required, and the mattress will be harder.

[0003] At present, people's living standards are constantly improving, and the demand for comfort and spine protection of sleeping mattresses is increasing. However, the current status of the independent pocket spring mattress industry has the following problems:

[0004] 1. The pocketed spring strips are bonded side by side with hot melt adhesive, and are evenly distributed side by side. The two adjacent springs on a pocketed spring strip are separated and independent after being hot-pressed with pocketed cloth. When a spring is stressed, the pocketed cloth will pull the adjacent springs to produce an interaction force. The spring cannot be subjected to the weight of the human body alone, which affects the sleeping experience.

[0005] 2. In addition, since a whole independent spring is arranged side by side and evenly, when it is used, the force will involve the springs around it, thus affecting the sleeping feeling and comfort. At the same time, it is arranged side by side, and there is a certain gap in the middle. The gap part has no spring support, so the comfort is not delicate enough;

[0006] 3. The existing bagged spring technology is that the spring steel wire needs to be preheated and then rolled into a spring before the spring is bagged. However, due to the continuous and uninterrupted rolling and bagging method, the heat treatment method is insufficient, the constant temperature time is short, and the temperature control is unstable. Then the spring is directly bagged. Such a process will cause the elasticity of the spring to decay easily and the fatigue strength to decrease, thereby shortening the service life and comfort.

[0007] 4. Each person has a different body shape and spinal curvature. Different parts of the body require different support forces, and the height difference formed after fitting with the mattress is also different. The springs in the existing independent pocket spring bed nets: the material of the steel wire, the wire diameter, the inner diameter of the spring, the number of turns, and the preload height are all unified, and cannot be customized according to the user's spinal curvature and comfort. Utility Model Content

[0008] The purpose of the utility model is to provide a detachable, assembled and customizable independent spring structure, bed net and mattress, so as to reduce the mutual entanglement of adjacent independent spring structures when subjected to force, improve the independent force of the independent spring structures, and then formulate a bed net that meets the personalized needs of customers to improve the technical effect of comfort, etc.

[0009] The utility model is realized by the following technical solutions:

[0010] A detachable, assembleable and customizable independent spring structure comprises a bag, wherein a spring core is arranged in the bag, and a hook is arranged at one end of the bag, and the end of the spring core can be hung in the hook. Connecting parts are arranged at both ends of the bag so that other independent spring structures can be connected side by side to form a side-by-side independent bag structure. Adhesive parts are also arranged on both sides of the bag.

[0011] To further explain, the above-mentioned side-by-side mainly refers to parallel arrangement and connection, which can be horizontal side-by-side connection or vertical side-by-side connection, and no excessive limitations are given here.

[0012] In order to better implement the present invention, further, the connecting portion is arranged close to one end of the bag, and the height of the connecting portion is one third to one half of the height of the bag.

[0013] In order to better realize the utility model, further, the bonding part is arranged close to one end of the bag, and the height of the bonding part is one fifth to one third of the height of the bag, and the bonding part includes a felt surface and a hook felt surface, the felt surface is located on one side of the bag, and the hook felt surface is located on the other side of the bag.

[0014] In order to better implement the utility model, further, there are at least two inverted hooks.

[0015] A detachable, assembleable, customizable independent spring bed net, the independent spring bed net comprising independent spring structures, a plurality of the independent spring structures being able to be arranged side by side to form a side-by-side independent bag structure;

[0016] The independent spring bed net is composed of a plurality of side-by-side independent bag structures, and adjacent side-by-side independent bag structures can be arranged in alignment or in a staggered arrangement.

[0017] A mattress, comprising the independent spring bed net, a bottom layer is further arranged at the bottom of the independent spring bed net, and a surface layer is further arranged on the top of the independent spring bed net;

[0018] The bottom layer comprises a knitted bottom layer and a fiber cotton bottom layer in sequence;

[0019] The surface layer comprises a sponge layer, a fiber cotton layer and a knitted surface layer in sequence.

[0020] The beneficial effects of the utility model are:

[0021] The utility model is provided with an independent spring structure, and connecting parts are provided at both ends of the independent spring structure. The height of the connecting parts only occupies one-third to one-half of the height of the bag. Adjacent independent spring structures are arranged side by side through the connecting parts to form a side-by-side independent bag structure. The side-by-side independent bag structure and other side-by-side independent bag structures form a bed net through the bonding part. When in use, the independent spring force structures are not involved with each other. Since the independent springs can be customized, the comfort of the mattress is improved. When lying on your back, it can meet the physiological curve of the body, and when sleeping on your side, it can meet the horizontal straight line of the spine, so as to achieve healthy sleep. This is because the connecting part has only a certain height. When the top of the independent spring structure is under pressure, the adjacent independent spring structures are not involved, so that the independent spring structures bear the corresponding pressure separately. When used, it can reduce the impact of other people's turning over on their own sleep, and improve the user experience.

[0022] The utility model provides an independent spring bed net, which is composed of an independent spring structure. The independent spring structures are arranged side by side to form side-by-side independent bag structures, and have multiple side-by-side independent bag structures. In the prior art, the side-by-side independent bag structures of the bed net are all arranged side by side, so that the gap in the middle is larger, and the supporting force of the gap is poor, which brings a poor experience to the user. The utility model connects the side-by-side independent bag structures with the side-by-side independent bag structures through the bonding parts on both sides of the pockets of the independent spring structure. The arrangement of the side-by-side independent bag structures can be planned according to user needs. Specifically, the specific installation position of the independent spring structure can be planned to reduce the retention of gaps, provide more comprehensive support, and provide users with a more delicate sense of comfort.

[0023] The independent spring bed net provided by the utility model can replace the conventional installation method. Since the independent spring structures are independent of each other and the forces can be separated from each other, they are not restricted by the surrounding independent spring structures. Therefore, the utility model is specially produced to be able to customize a special bed net that meets the user's situation and needs. Specifically, by measuring the user's body data and sleeping habits, the stiffness and prestress borne by the independent spring structure in the corresponding area are measured, and then the inner diameter of the spring, the number of turns, etc. can be further measured, so as to prepare a unique bed net and mattress that meet the user's needs.

[0024] The utility model calculates the stiffness, preload, number of springs, spring radius, number of spring coils, etc. corresponding to each part according to the measured data of each part of the human body, and customizes the spring core according to the data. After the customized spring core is bagged, it forms a bed net through a connecting part and an adhesive part. When in use, it can meet the physiological curve of the body when sleeping on the back, and can meet the horizontal straight line of the spine when sleeping on the side, so as to achieve healthy sleep.

[0036] The technical solution of the present invention will be described below in conjunction with the accompanying drawings of the present invention.

[0037] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present utility model, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] Please see Figures 1 to 8 The utility model provides an independent spring structure. In the prior art, strips of bagged spring strips are bonded side by side with hot-melt adhesive, and are evenly distributed side by side. Two adjacent springs are separated after being bagged by hot pressing. When one of the springs is subjected to force, the bagged cloth will pull the adjacent springs, causing interaction forces, which will lead to a poor user experience. In order to solve the above technical problems, the utility model optimizes the structure to achieve a mutually independent structure, which is not affected by the surrounding springs, thereby improving the sleep quality and comfort.

[0039] like Figure 1 As shown in .2.3, the bag 10 includes a sleeve 10. When the spring core 11 is bound, one end of the sleeve 10 is provided with an opening, and the other end is provided with a seal, and a barb 12 is provided at the open end. After the spring core 11 is bound into the sleeve, the end of the spring core 11 is hooked by the barb 12. The purpose of setting the barb 12 is to better hook and fix the spring core 11, prevent the spring core 11 from deforming during use, and enhance stability. Therefore, it is preferred that the number of the barb 12 is at least 2. As shown in the figure, the barb 12 has 4 and is evenly distributed in the sleeve 10. The height of the spring core 11 is greater than the height of the sleeve 10. After bagging, the force between the spring core and the sealed end is the preload of the independent spring structure. The magnitude of the preload is the force corresponding to the compression of the spring core 11 to the height of the sleeve 10. The magnitude of the preload determines the comfort level, and at the same time achieves the purpose of firmly hooking the spring core 11 in the sleeve 10.

[0040] In addition to the above-mentioned structure, connecting parts 13 are provided at both ends of the bag 10 (the two ends refer to the end parts on the circumferential side of the bottom of the bag 10, which can also be called two sides). Other independent spring structures can be connected side by side through the connecting parts 13, as shown in the figure. In addition, bonding parts are provided on both sides of the bag 10, and their function is to bond other independent spring structures.

[0041] The height of the connecting portion 13 and the bonding portion is one fifth to one third of the height of the bag 10, and one third is selected in this embodiment. When multiple independent spring structures are connected side by side, their bottoms are connected to each other, but their tops are not connected. The connecting portion 13 can be connected by hot melting or sewing. Since there is no connection at the top, when subjected to force, the forces of adjacent independent spring structures are also independent of each other, and there will be no transition involving adjacent structures, which will bring a poor experience.

[0042] The independent spring core 11 is customized, the stiffness of the spring core 11 is very precise, the spring core 11 is more fully heat-treated, and can also provide a favorable premise for user comfort, and can also extend the service life of the independent spring pocket structure.

[0043] In the process of preparing the existing bed net, the independent spring pocket structure is arranged side by side, so that the pores in the middle are larger, and the pores are not strong enough to support the user. Figure 5 , which will also bring a bad experience to the user. Therefore, in order to be able to arrange in multiple ways, bonding parts are also provided on both sides of the bag, and the bonding parts include a felt surface 14 and a hook felt surface 15. The independent spring bag structures of adjacent side-by-side independent bag structures can be bonded to each other through the combination of the felt surface 14 and the hook felt surface 15, thereby reducing the pores and improving the comprehensiveness of the support, thereby achieving a better bed net structure and providing a better user experience. Figure 4 shown.

[0044] The bed net can be made according to the above method, and the mattress can be customized according to the user's situation. The operation of customizing the mattress is as follows:

[0045] Measuring the user's body data:

[0046] Including human parameters: height, weight, BMI value, record sleeping habits: side sleeping, back sleeping, lying down sleeping, as well as the softness and comfort of your favorite mattress.

[0047] The utility model can calculate the stiffness and prestress of the springs corresponding to different areas in the bed net according to the user's data, and then customize the springs according to the spring conditions in different areas to customize spring cores with different steel wire diameters, different numbers of turns and different heights, and then customize an independent spring structure.

[0048] During the processing of the spring core 11, the spring steel wire is preheated sufficiently before being installed in the sleeve, thereby improving the service life of the spring core 11, anti-fatigue strength, and extending the service life.

[0049] The customization process begins with measuring the body data and finding out the number of springs in each area, as shown in the following figure:

[0050] Then measure the values ​​of the human body's shoulders and waist in different states, as follows:

[0051] F'1: The preload of the bed net under the contact area between the shoulder and the mattress when sleeping on the side is the sum of the preloads of the independent spring structure (the bed net will move downward only after reaching this pressure)

[0052] F1: The preload of the bed net under the contact area between the waist and the mattress when sleeping on the side is the sum of the preloads of the independent spring structure (the bed net will move downward only when this pressure is reached)

[0053] F'2: The preload of the bed net under the contact area between the shoulder and the mattress when sleeping on your back is the sum of the preloads of the independent spring structure (the bed net will move downward only when this pressure is reached)

[0054] F2: The pre-pressure of the bed net under the contact area between the waist and the mattress when sleeping on your back (the bed net will move downward only after reaching this pressure)

[0055] When sleeping on your back, the number of spring cores under the contact force area between the waist and the mattress is: a

[0056] When sleeping on your side, the number of spring cores under the contact force area between the waist and the mattress is: c

[0057] The number of spring cores under the contact area between the shoulder and the mattress when sleeping on your back is: b

[0058] When sleeping on your side, the number of spring cores under the contact area between the shoulder and the mattress is: d

[0059] The uniform preload of each independent spring structure under the waist area is: F

[0060] The spring constant of each spring core in the waist area is: KWaist

[0061] The uniform preload of each independent spring structure in the shoulder area is: Fshoulder

[0062] The spring constant of each spring core under the shoulder area is: Kshoulder'

[0063] S'1: The contact area between the shoulder and the mattress when sleeping on the side

[0064] S'2: The contact area between the shoulder and the mattress when sleeping on your back

[0065] S1: The contact area between the waist and the mattress when sleeping on the side

[0066] S2: The contact area between the waist and the mattress when sleeping on your back

[0067] L0: The height of the waist when sleeping on the side (this value needs to be predetermined. The higher the L0, the softer the bed net is when sleeping on the side, and the stronger the bed net wraps the body. Conversely, the lower the L0, the harder the bed net is when sleeping on the side, and the better the bed net supports the body)

[0068] L1: When the human body is standing sideways, the horizontal distance between the waist concave point and the shoulder convex point is taken as the basic force point (also the height difference between the waist force point and the shoulder force point when sleeping on your back)

[0069] L2: When the human body is standing upright, the horizontal distance between the waist concave point and the shoulder convex point is taken as the basic force point (also the height difference between the waist force point and the shoulder force point when sleeping on the side)

[0070] G1: Gravity in the shoulder area (gravity remains the same when sleeping on your side or back)

[0071] G2: Gravity in the lumbar area (gravity remains the same when sleeping on your side or back)

[0072] in:

[0073] S1 / S2=F1 / F2=c / a (the area is proportional to the number of springs)

[0074] S'1 / S'2=F'1 / F'2=d / b (the area is proportional to the number of springs)

[0075] G2=F2=a*F waist (waist in supine sleeping position, as the basic reference point)

[0076] G2=F1+c*K waist*L0=c*F waist+c*k waist*L0 (waist side sleeping state)

[0077] G1=F'2+b*Kshoulder*L1=b*Fshoulder+b*Kshoulder*L1 (shoulder supine sleeping state)

[0078] G1=F'1+d*Kshoulder(L0+L2)=d*Fshoulder+d*Kshoulder*(L0+L2) (shoulder side sleeping state)

[0079] By using the above values ​​and combining with the following calculation formula, the stiffness and preload of the spring core 11 are calculated and the calculation formula is given:

[0080] The stiffness calculation formula of each spring at the waist position is as follows:

[0081] K waist = (ac)*G2 / a*c*L0

[0082] The calculation formula for the preload of each spring at the waist position is as follows:

[0083] F waist = G2 / a.

[0084] The stiffness calculation formula of each spring at the shoulder position is as follows:

[0085] K shoulder = (bd)*G1 / b*d*(L0+L2-L1)

[0086] The calculation formula for the preload of each spring at the shoulder position is as follows:

[0087] F shoulder=G1*(L0+L2-b*L1 / d) / b*(L0+L2-L1).

[0088] Through the above-mentioned customization method, each independent spring structure that meets the individual characteristics of the customer can be formulated, and connected according to the corresponding positions to form a bed net, and then the bed net is added between the bottom layer and the surface layer to form a mattress. In this embodiment, the bottom layer includes a knitted bottom layer and a fiber cotton bottom layer, and the surface layer includes a sponge layer, a fiber cotton layer, and a knitted surface layer in sequence. The structure of the surface layer and the bottom layer can be added or reduced according to customer needs, and the structure of the surface layer and the bottom layer both belong to the inner lining layer of the existing conventional mattress and can be directly purchased and processed on the market. The bed net produced after the above-mentioned customization and the mattress after arrangement are more in line with the user's usage habits, thereby improving the user's sleep quality and user experience.

[0089] To further explain, in addition to the calculation of the stiffness and preload of the shoulders and waist listed above, the stiffness and preload of important parts of the human body such as the head, neck, back, buttocks, thighs, calves, and feet can be further calculated. The calculation method is the same as that of the shoulders mentioned above, and will not be elaborated here. In addition, after calculating the stiffness and preload of important parts, the number of springs in that part, the height of the spring, the middle diameter of the spring, the number of coils of the spring, the diameter of the steel wire, the heat treatment of the spring and other parameters can be calculated accordingly, and then customization can be carried out. The calculations are all conventional technical methods in the industry, so they will not be elaborated here.

[0090] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
