Description

Technical Field

[0001] This utility model relates to the field of mattress spring technology, and in particular to a moisture-proof, noise-reducing independent pocket spring and a spring mattress. Background Technology

[0002] Pocket springs are widely used in upholstered furniture such as spring mattresses and sofas. By individually wrapping and sealing each spring in a cloth bag, they effectively prevent the springs from rubbing against each other and generating noise.

[0003] However, existing pocket springs generally use ordinary non-woven fabric or cotton linen as the wrapping material, which has the following technical shortcomings: 1) Ordinary non-woven fabrics are not durable enough and will turn to powder after long-term use. They also have poor breathability, which can easily accumulate moisture, breed bacteria and mites, and threaten human health. 2) Ordinary non-woven fabrics have insufficient moisture resistance, and moisture in the environment can easily penetrate into the bag chamber, causing the springs to rust and shortening the product's service life. 3) Under long-term dynamic load, the metal end face of the spring will continuously rub against the inner wall of the bag, which can easily wear through the bag from the inside. This will not only produce abnormal noise, but may also cause the spring to be punctured, thus causing the structural failure of the bag spring.

[0004] Therefore, overcoming the problems of insufficient moisture resistance, insufficient durability, and easy wear and tear of the bag chamber from the inside, which can cause abnormal noise, is a technical problem that urgently needs to be solved. Utility Model Content

[0015] The aforementioned moisture-proof, noise-reducing, individually pocketed springs and spring mattresses have the following beneficial effects: 1) The moisture-proof and noise-reducing independent pocket spring of this utility model uses the pocket chamber on the encapsulation body to wrap the helical spring, which can effectively block the intrusion of external moisture, prevent the internal spring from rusting, and extend the service life of the product. 2) The moisture-proof and noise-reducing independent pocket spring of this utility model disperses the concentrated stress on the inner wall of the spring and the inner wall of the pocket by setting a gasket on the end face of the spring support part on the inner wall of the pocket, effectively solving the problem of friction noise caused by the spring wearing through the pocket from the inside, and improving the structural integrity and long-term reliability of the pocket spring. 3) The moisture-proof and noise-reducing independent pocket spring of this utility model has a casing made of cool cloth, which is both breathable and durable.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0022] One embodiment of this utility model provides a moisture-proof, quiet, independently pocketed spring, see reference. Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The moisture-proof and noise-reducing independent pocket spring includes: a helical spring 2 and a casing 1 made of PVC fabric; the casing 1 is provided with at least one pocket chamber 13, and the helical spring 2 is wrapped inside the pocket chamber 13; the helical spring 2 includes an upper support part 21, a helical elastic body 22 and a lower support part 23 arranged sequentially from top to bottom; a first gasket is fixed to the inner wall of the pocket chamber 13 corresponding to the end face of the upper support part 21; a second gasket is fixed to the inner wall of the pocket chamber 13 corresponding to the end face of the lower support part 23.

[0023] Preferably, the cool fabric is a nonwoven fabric made of water-repellent fiber material that has undergone carding, web laying, entanglement needle punching, and heat setting. The heat setting process includes four stages: preheating, heat penetration, molecular chain adjustment, and cooling setting. The water-repellent fiber material can be any one of polyester fiber, polypropylene fiber, and nylon fiber. Compared to ordinary nonwoven fabrics or cotton / linen fabrics, this cool fabric forms a stable mesh structure through entanglement needle punching, effectively resisting compression deformation. Heat setting further fixes the fiber structure, allowing the material to maintain good resilience even after long-term use. Simultaneously, the cool fabric also possesses good air permeability and water repellency, ensuring a dry internal environment for the bag chamber 13, thereby effectively preventing spring corrosion caused by moisture intrusion and extending the service life of the individually pocketed springs.

[0024] Specifically, the package 1 is a single-chamber or multi-chamber structure made of a piece of fabric. (See reference) Figures 1 to 3 When the package 1 adopts a single-chamber structure, the single-chamber structure is sealed to form a sealed chamber 13 through the longitudinal sealing weld lines 12 on both sides and the transverse sealing weld line 11 in the middle. (Reference) Figure 6 and Figure 7 When the package 1 adopts a multi-chamber structure, the multi-chamber structure is sealed to form multiple linearly arranged chambers 13 by a common transverse sealing weld line 11 and multiple parallel longitudinal sealing weld lines 12.

[0025] The transverse sealing weld line 11 extends along the length of the package 1 and is located in the middle of the package 1; the longitudinal sealing weld line 12 extends along the height of the package 1 and is located on both sides of the bag chamber 13. The shape of the longitudinal sealing weld line 12 between adjacent bag chambers 13 can be set according to the number of sealing weld lines. For example, when there is a single longitudinal sealing weld line, it is straight. When there are two longitudinal sealing weld lines, each longitudinal sealing weld line 12 includes a straight line in the middle section and a transition arc connecting the curved surfaces of the bag springs on both sides. The two longitudinal sealing weld lines 12 are axially symmetrical about the center line of the adjacent independent bag springs.

[0026] The helical spring 2 is made of metal wire wound together and includes an upper support part 21, a helical elastic body 22 and a lower support part 23 in sequence along its axial direction. The upper support part 21 and the lower support part 23 are closed, approximately planar support rings, and the helical elastic body 22 is a helical coil structure that provides the main buffering function. The wire diameter, number of turns and pitch of the helical coil structure are set according to the stiffness requirements.

[0027] Secondly, a gasket is provided on the inner wall of the bag chamber 13 corresponding to the end faces of the two supports of the helical spring 2. The gasket can be made of the same material as the encapsulation body 1, and the gasket is circular in shape and its size is adapted to the support. The gasket can buffer and disperse the concentrated stress on the end face of the support against the inner wall of the bag chamber 13, effectively preventing the support from wearing through the bag chamber 13 under long-term impact, thereby improving the durability of the individually pouched cartridge.

[0028] The aforementioned moisture-proof, quiet, individually pocketed springs have the following beneficial effects: 1) The moisture-proof and noise-reducing independent pocket spring in this embodiment uses the pocket chamber 13 on the encapsulation body 1 to wrap the helical spring 2, which can effectively block the intrusion of external moisture, prevent the internal spring from rusting, and extend the service life of the product. 2) The moisture-proof and noise-reducing independent pocket spring in this embodiment disperses the concentrated stress on the inner wall of the spring end face of the spring support part by setting a gasket on the inner wall of the pocket chamber 13. This effectively solves the problem of friction noise caused by the spring wearing from the inside or even puncturing the pocket chamber 13, and improves the structural integrity and long-term reliability of the independent pocket spring. 3) The moisture-proof and noise-reducing independent pocket spring in this embodiment has a housing 1 made of breathable and durable fabric, which can dissipate moisture in time and inhibit the growth of bacteria and mites, providing users with a healthy and dry sleeping environment.

[0029] As a preferred embodiment, the inner wall of the fabric is provided with a low coefficient of friction coating.

[0030] The low friction coefficient coating is a water-based polyurethane coating or a modified silicone resin coating.

[0031] When using a water-based polyurethane coating, the water-based polyurethane is uniformly scraped or sprayed onto the inner wall of the bag chamber 13. After drying, a coating with a thickness of 0.01 to 0.05 mm is formed. This coating can effectively reduce the friction between the helical spring 2 and the inner wall of the bag chamber 13 during compression and rebound, thereby reducing noise.

[0032] When a modified silicone resin coating is used, the modified silicone resin is uniformly coated onto the inner wall of the bag chamber 13 by dip-coating. Then, it is thermo-cured at a temperature of 100-50°C to form a smooth coating with a thickness of 0.005-0.03 mm. This coating not only has an extremely low coefficient of dynamic friction, but also can be firmly bonded to the fabric material (i.e., water-repellent fiber material), thereby effectively inhibiting coating peeling during use and further improving the durability and noise reduction effect of the bag chamber 13.

[0033] The modified silicone resin is a copolymer emulsion, prepared by copolymerizing pure silicone resin with epoxy or polyester resin, which has strong adhesion to water-repellent fiber materials. The epoxy or polyester segments in the modified silicone resin molecular chain are well compatible with the fiber material, thereby enhancing the adhesion between the coating and the fabric.

[0034] Understandably, the moisture-proof and noise-reducing independent pocket spring of this embodiment reduces the frictional resistance between the inner wall of the pocket chamber 13 and the coil spring 2 by providing a low-friction coefficient coating on the inner wall of the pocket chamber 13, thereby achieving the noise reduction of the overall pocket spring structure.

[0035] In a preferred embodiment, reference Figure 5 The helical elastomer 22 has an equal-pitch cylindrical structure.

[0036] That is, the helical spring 2 in this embodiment is composed of an upper support part 21, multiple helical coils with equal pitch and a lower support part 23 connected sequentially from top to bottom. The helical spring 2 with the above structure is simple and can provide uniform and continuous support force.

[0037] In another preferred embodiment, reference Figure 4 The helical elastomer 22 is a variable stiffness structure; the helical elastomer 22 includes at least two elastic segments, and the pitch of adjacent elastic segments along the axial direction is different.

[0038] That is, in this embodiment, the helical spring 2 is connected from top to bottom to an upper support 21, a first elastic segment 221, a second elastic segment 222, and a lower support 23. The number of coils in the first spring segment is greater than the number of coils in the second elastic segment 222, and the pitch of the first spring segment is smaller than the pitch of the second spring segment. For example, the first elastic segment 221 is made of 4 helical coils with a pitch of 10mm, and the second elastic segment 222 is made of 3 helical coils with a pitch of 40mm.

[0039] The helical spring 2 with the above structure has a phased response support characteristic. In the initial compression stage, the first elastic segment 221 with more coils and a smaller pitch is compressed first. Its easy deformation characteristic can quickly conform to the body curve, effectively relieve the initial pressure and enhance comfort. In the deep compression stage, the second elastic segment 222 with fewer coils and a larger pitch intervenes. Its higher stiffness provides strong stable support, effectively preventing collapse and enhancing durability. That is, this variable stiffness design with upper softness and lower toughness has both a close-fitting softness and a deep stable support force, which can better adapt to the differentiated force needs of different parts of the human body from head to toe.

[0040] The preparation method of the moisture-proof, quiet, individually pocketed springs described in the above embodiments is as follows: Step S10: After combing and laying the water-repellent fiber material into a web, it is entangled and needle-punched to obtain a fabric.

[0041] Specifically, the water-repellent fiber material (such as polyester fiber) is first opened and combed to obtain a fiber web; then, the fiber web is introduced into a needle punching machine, and the fibers are entangled in multiple directions through a three-dimensional entanglement needle punching process to form a fabric with a network structure.

[0042] Step S20: Heat set the fabric to obtain Cool Fabric.

[0043] Specifically, heat setting includes four stages: preheating, heat penetration, molecular chain adjustment, and cooling setting. In this case, step S20 specifically includes the following steps: The fabric is fed into a hot air tenter frame and passes through a preheating zone, a tenter frame, and a cooling zone in sequence to complete the setting process and obtain the Cool Fabric. The preheating zone is used to heat the fabric to a preset setting temperature. The tenter frame is used to perform heat penetration and molecular chain adjustment on the fabric at the preset setting temperature. The cooling zone is used to cool the fabric to a preset cooling temperature to fix the fiber structure.

[0044] That is, in the first step, the fabric obtained in step S20 is sent to the preheating zone of the hot air tenter frame, and the fabric is heated to the preset setting temperature before being sent to the tenter frame.

[0045] The preset setting temperature is typically higher than the fabric's glass transition temperature but lower than its melting point. Specifically, this setting temperature is determined based on the fabric's constituent raw materials and their blending ratio. For example, the setting temperature for polyester fiber fabrics is set to 180℃~210℃. Understandably, if the setting temperature is too low, the fabric's breaking strength may be insufficient, potentially causing the resulting pocket springs to expand excessively after prolonged use, even bursting the pocket chamber. Conversely, if the setting temperature is too high, the fabric may become too stiff, affecting its feel and increasing the coefficient of friction, leading to unusual friction noises in the resulting pocket springs.

[0046] The second step involves heat penetrating the fabric at a preset setting temperature upon entering the stretching and setting zone. After heat penetrating, the fabric undergoes molecular chain adjustment under tension before being sent to the cooling zone.

[0047] Specifically, when the fabric leaves the preheating zone and enters the stretching and setting zone, it is maintained at the preset setting temperature for a preset time, allowing heat energy to penetrate from the fabric surface to the interior, thereby enabling the entire fabric to reach a uniform setting temperature. The time of this heat penetration process is determined based on the fabric's unit area weight and the fiber's thermal conductivity. When the entire fabric reaches the setting temperature, under tension, the weaker secondary valence bonds in the fibers are broken, causing the molecular chain segments to rearrange and orient along the direction of the external force, establishing new intermolecular forces. The time for this molecular chain adjustment process is 1 to 2 seconds.

[0048] The third step is to force the fabric to cool to a preset cooling temperature when it enters the cooling zone.

[0049] The preset cooling temperature is 20°C. Specifically, when the fabric leaves the tenter frame and enters the cooling zone, it is rapidly cooled to 20°C by cold air or cooling rollers, which fixes the fibers in a new molecular arrangement before finally being laid.

[0050] Furthermore, to verify the performance of the spunlace fabric obtained by the present invention through steps S10 and S20, performance tests were conducted on the spunlace fabric and an existing spunlace fabric (i.e., spunlace nonwoven fabric). The preparation process of the existing spunlace fabric is as follows: Step a, Raw material processing: Mix, loosen, and comb polypropylene and other fiber raw materials into a web; Step b, fiber reinforcement: The fiber web is reinforced using a hydroentangling process; Step c, drying and post-processing: After dehydration and drying of the nonwoven fabric obtained through reinforcement, the dried nonwoven fabric is slit, printed and embossed to obtain the final product.

[0051] The performance tests include water repellency testing, coefficient of friction testing, abrasion resistance testing, and noise testing. The water repellency test involves cutting the fabric sample from this application and existing fabric samples separately, immersing the samples in a water-filled container until the water completely covers the fabric, and recording the maximum time without water seepage. The coefficient of friction test is conducted according to standard ASTM D1894, "Standard Test Method for Static and Dynamic Coefficients of Friction of Plastic Films and Sheets," and the static coefficient of friction is recorded. The abrasion resistance test involves placing the fabric sample on an abrasion testing machine and, after 5000 cycles of friction, observing the surface of the sample under a microscope to see if pilling occurs. The noise test involves using the fabric from this application and existing fabrics to create individual pocket springs, and using a universal testing machine to continuously compress the springs 50 times at a constant speed (compressing them to 50% of their original height). A calibrated decibel meter is placed 2 cm away from the spring, and the maximum sound pressure level generated in each compression cycle is recorded. The average of the 50 tests is taken as the final result. The performance test results are shown in Table 1.

[0052] Table 1. Performance Test Comparison Table of the Coolbu in this Application and Existing Coolbu

[0053] As shown in Table 1, the Cool Fabric of this application has better water repellency, abrasion resistance and noise reduction performance compared with existing Cool Fabric, and has a lower coefficient of friction, which can effectively reduce the noise of pocket spring products.

[0054] Step S30: Cut the target fabric of the preset size from the cool fabric.

[0055] That is, based on the size parameters of the coil spring (i.e., the outer diameter and free height of the spring) and the layout requirements, cut out the required size of the fabric as the target fabric.

[0056] Step S40: After assembling the target fabric, the gasket group and the helical spring, seal them to form an independent pocket spring.

[0057] That is, a set of gaskets is fixed on the target fabric and a spiral spring is placed in the middle of the gasket set. The target fabric is then melted and sealed by hot rolling or ultrasonic bonding to form a sealed independent pocket spring. This sealing method forms a holeless sealing structure, which can avoid water seepage caused by thread holes compared to the sewing process, thus having a better moisture-proof effect.

[0058] Preferably, step S40 includes the following steps: Step 1: Fix the pad assembly to the target fabric and place the helical spring at the corresponding position of the pad assembly.

[0059] The gasket assembly includes a first gasket and a second gasket that correspond to the upper and lower end faces of the helical spring, respectively.

[0060] Specifically, the positioning areas for fixing the gaskets are marked on the cut fabric (i.e., the target fabric). The hot melt adhesive pre-applied to the surfaces of the first and second gaskets is melted by a hot pressing process, thereby firmly bonding the two first and second gaskets to the corresponding positioning areas. Finally, the upper and lower support parts of the coil spring are placed on the edges of the corresponding gaskets to ensure that the end face of the coil spring is aligned with the gasket when the fabric is sealed.

[0061] Step two: The target fabric containing the helical spring is ultrasonically welded to form an independent pocket spring.

[0062] Understandably, the aforementioned individually pocketed springs can be as follows: Figure 1 The single spring shown or as Figure 6 The image shows a spring string consisting of multiple springs.

[0063] When an independent pocket spring is a single spring, the two ends of the target fabric are first folded towards the middle to wrap the helical spring, forming a bag structure with three unsealed edges. Then, the three unsealed edges of the bag structure are ultrasonically welded to form the independent pocket spring. The three unsealed edges are located on both sides and in the middle of the bag structure.

[0064] When the individual pocket springs are spring strings, multiple sets of gaskets and helical springs are laid on the target fabric. The spacing of the helical springs is set according to the sealing weld lines formed by ultrasonic welding. The two ends of the target fabric are folded towards the middle to wrap all the helical springs. Multiple parallel longitudinal sealing weld lines are formed by ultrasonic welding, thereby producing a series of interconnected individual pocket springs, i.e., spring strings.

[0065] Based on the same inventive concept, an embodiment of this utility model also provides a spring mattress, see reference. Figure 8 and Figure 9 The spring mattress includes a spring core 100, which includes a plurality of moisture-proof and noise-reducing individually pocketed springs 10 of the above embodiments arranged in an array, and the encapsulations of adjacent moisture-proof and noise-reducing individually pocketed springs 10 in a row are interconnected.

[0066] That is, firstly, multiple moisture-proof and noise-reducing individually pocketed springs 10 are arranged horizontally to form a spring column. The encapsulation bodies of adjacent moisture-proof and noise-reducing individually pocketed springs 10 in the spring column are connected to each other by sealing welding wire. When the moisture-proof and noise-reducing individually pocketed springs 10 are spring strings, they themselves constitute a complete spring column. Then, multiple spring columns are arranged vertically to form a spring bed core 100.

[0067] In a preferred embodiment, the moisture-proof and noise-reducing independent pocket springs 10 in different columns are fixedly connected by connectors.

[0068] The connector can be either a connecting wire or tape.

[0069] Specifically, after the moisture-proof and noise-reducing independent pocket springs 10 are arranged horizontally to form a spring column, a connection point is set on each spring column. The connection point is located at both ends of the center line between adjacent moisture-proof and noise-reducing independent pocket springs 10. At this time, the spring bed core 100 with a stable structure can be formed by connecting the connection points in the same row of each spring column through connecting lines or tape.

[0070] The above-mentioned spring mattress has the following beneficial effects: 1) The spring mattress of this embodiment includes a spring core 100 formed by an array of multiple moisture-proof and noise-reducing independent pocket springs 10. The multiple array of moisture-proof and noise-reducing independent pocket springs 10 together form a support plane, which can provide uniform and close support and effectively avoid the occurrence of local collapse. 2) In this embodiment of the spring mattress, the adjacent moisture-proof and noise-reducing independent pocket springs 10 are interconnected, which can effectively absorb or reduce the vibration and noise generated when the springs move, ensuring that the entire spring core 100 remains highly quiet under dynamic load. 3) In the spring mattress of this embodiment, the moisture-proof and noise-reducing independent pocket spring 10 is made of cool fabric, which has good breathability, durability and moisture resistance.

[0071] In a preferred embodiment, the spring mattress further includes an upper fabric layer 300, a comfort layer 200, an antibacterial layer 400, and a lower fabric layer 500, wherein the upper fabric layer 300, the comfort layer 200, the spring core 100, the antibacterial layer 400, and the lower fabric layer 500 are stacked sequentially.

[0072] Understandably, the top layer 300 can be made of knitted fabric; the comfort layer 200 can be made of high-density, high-resilience foam to improve the comfort and resilience of the mattress; the antibacterial layer 400 can be made of firm jute, such as Bengal jute, which has antibacterial and anti-mite properties; and the bottom layer 500 can be made of 3D fabric, which is breathable and also makes the mattress durable.

[0073] The layers of the spring mattress are bonded together with an adhesive material, preferably an environmentally friendly adhesive, hot melt adhesive, etc.

[0074] The aforementioned spring mattresses also have the advantages of being antibacterial and highly comfortable.

[0075] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model.
