[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
[0021] Please refer to Figures 1 to 2 A first embodiment of a spring A with a soft spring area for a mattress provided by the present application has a first soft spring area (11) with a pitch and a core diameter gradually increasing from one end to the other end, a first buffer area (12) with a pitch and a core diameter larger than the first soft spring area (11), a supporting area (13) with a core diameter smaller than or a pitch larger than the first buffer area (12), a second buffer area (14) with a structure identical to the first buffer area (12), and a second soft spring area (15) with a pitch larger than the first soft spring area (11).
[0022] In the present embodiment, the first soft spring area (11) is a spring coil with a pitch and a core diameter gradually increasing, and the effective number of turns is at least two turns.
[0023] In the present embodiment, the first buffer area (12) is a spring coil with a pitch and a core diameter gradually increasing, and the effective number of turns is at least two turns.
[0024] In the present embodiment, the supporting area (13) is a spring coil, and the effective number of turns is at least one turn.
[0025] The second buffer area (14) is a spring coil with a pitch gradually decreasing, and the effective number of turns is at least two turns.
[0026] The second soft spring area (15) is a spring coil with a pitch and a core diameter gradually decreasing, and the effective number of turns is at least two turns.
[0027] It is worth mentioning that the first soft spring area (the first layer of spring from top to bottom) has a smaller caliber and core diameter, the smallest pitch and the most number of turns in the whole spring, a soft hardness, a prominent independent support effect, and no mutual interference. The quiet effect is better, and it plays a point-to-point support and wrapping effect on the human body, and plays a massage effect. It replaces the additional independent mini spring (commonly known as bread spring) on the bed core, solves the problems of displacement and uneven distribution caused by the difficulty of fixing after stacking due to the easy shrinkage of the bread spring, significantly saves the labor and material costs, and at the same time enhances the firmness and comfort of the mattress.
[0028] The first buffer area (the second layer of spring from top to bottom) has the largest core diameter (similar to the core diameter of the second buffer area), a moderate pitch, a moderate softness and hardness, and plays a role of buffering the upper layer and conducting stress downward. The structural design not only saves the material of the comfort layer, but also avoids the phenomenon of sinking and difficulty in turning over caused by the over-thickness of the wrapping material. Through the soft elasticity, it can quickly release the body pressure, improve the sleep experience, and help the user naturally adjust the sleeping posture in a deep sleep state.
[0029] The supporting area (the third layer of spring from top to bottom) has a smaller core diameter or a larger pitch, and the highest hardness, and bears the main supporting role of the whole spring combination. Due to the small core diameter or large pitch and high hardness, a relatively thin steel wire is used to achieve the hardness effect of a thicker wire diameter in the traditional spring structure. This design not only maintains the elasticity and supporting force of the thicker steel wire, but also can be configured into different softness and hardness of bread massage springs at both ends, improves the overall stability of the elastic system, and meets the personalized comfort needs.
[0030] The second buffer area (the fourth layer of spring from top to bottom) has a core diameter similar to that of the first buffer area, a moderate pitch, and a moderate softness and hardness. As a lower buffer system, it can effectively absorb the stress conducted from top to bottom, and has a buffering effect similar to "soft landing of heavy objects".
[0031] The second soft spring area (the fifth layer of spring from top to bottom) has a structure similar to the first soft spring area, but the pitch and core diameter are slightly larger, so the hardness of this layer is larger than that of the first soft spring area. It maintains independent support and non-interference, and is suitable for users who prefer a harder comfort layer. If it is not necessary to distinguish the different softness and hardness of the two sides of the mattress, or in order to reduce the cost, the fifth layer can be selected to be cancelled. When the fifth layer is cancelled, it is the second embodiment of the present application, as shown in Figure 3As shown, a spring for a mattress with a soft spring area has a first soft spring area 11A, a first buffer area 12A with a pitch and a core diameter larger than the first soft spring area 11A, a supporting area 13A with a core diameter smaller or a pitch larger than the first buffer area 12A, and a second buffer area 14A consistent with the first buffer area 12A.
[0032] As shown, a spring bed net provided by the present application can freely adjust the core diameter and pitch of each area to achieve ideal softness and elasticity. Figure 4 As shown, a spring bed net provided by the present application can freely adjust the core diameter and pitch of each area to achieve ideal softness and elasticity.
[0033] It is worth noting that the two adjacent springs have a spacing between them to reduce point-to-point friction and effectively reduce noise. This structure enhances the independence between layers and improves the elasticity and comfort of the spring system, allowing users to enjoy a more peaceful and comfortable sleep experience during use.
[0034] The material of the cylindrical cloth bag B is any one of cotton, linen, denim, non-woven fabric, etc., and the adjacent two cylindrical cloth bags B are packaged on the side or back by ultrasonic or sewing equipment. The two springs can be packaged in a straight line or in a curve (the curve packaging effect is different from the traditional straight line packaging of independent bagged springs. It is to package the contour of multiple spring combinations in a curve. This design can perfectly wrap and fix the shape of the spring, avoid unnecessary shaking, interference and noise caused by spring walking deformation, and improve the structural stability and service life).
[0035] The connection and assembly method of the spring mattress: the second layer, the fourth layer and the third layer of the adjacent two groups of springs are connected and assembled, which can adopt the connection and assembly method of the traditional independent bagged spring bed net (such as adhesive, buckle, buckle, threading, etc.), or can adopt glue-free assembly and other assembly methods such as four-leaf clover-shaped ultrasonic welding.
[0036] The advantages of the present application are:
[0037] 1. Simple and reliable structure: under the premise of better independent bagged spring bed net stacking and combination effect of several different softness and hardness, the weight of the entire spring system can be greatly reduced, and the height of the spring system can be more conveniently adjusted. The production process is simplified, and the stretchability and structural stability of the spring are improved.
[0038] 2. Cost saving: reduces raw material consumption and labor costs in the production process, effectively reducing overall manufacturing costs.
[0039] 3. Durability and stability: the special and simple structure of the elastic system avoids problems such as jamming, misalignment, and wear caused by the stacking of several independent pocket springs with different hardness, enhancing durability.
[0040] 4. Low noise: the first layer is independently distributed and does not generate friction; the second and fourth layers have large core diameters but small contact surfaces; and the third layer has a small core diameter but good support. Each layer is distinct and does not interfere with the others, resulting in even lower noise.
[0041] 5. More personalized: although the elastic system is divided into five layers, each layer is distinct and has a clear function, and individualized sleep customization can be achieved by adjusting the diameter, core diameter, pitch, and number of turns of the five layers of springs according to customer needs.
[0042] 6. More scientific, environmentally friendly, and diverse assembly method: the utility model not only retains the traditional independent pocket spring bed net adhesive assembly method, but also through innovative design, completely realizes glue-free fixing, meeting environmental protection requirements. A multi-layer independent pocket spring bed core replaces and surpasses the traditional independent pocket spring bed net stack combination bed core.
[0043] 7. Strong comfort: through soft elasticity, it can quickly release human pressure, improve sleep experience, help users naturally adjust their sleep position in a deep sleep state, and solve the problem of lack of comfort in market four-leaf clover-shaped springs.
[0044] The above-described embodiments are merely examples of the utility model and do not limit the scope of the utility model's patent, and any equivalent structure or equivalent process conversion using the utility model specification and drawings, or direct or indirect application in other related technical fields, are also included in the utility model's patent protection scope.
