Description

Technical Field

[0001] This utility model relates to the technical field of mattresses, and in particular to a double-layer spring mattress. Background Technology

[0002] Double-spring mattresses are the core of a high-performance mattress, consisting of two layers of independently pocketed springs of different sizes stacked vertically. Typically, the upper layer uses thinner, softer springs for close-fitting cushioning, while the lower layer uses thicker, firmer springs for stable support. This structure allows for precise zoned support, effectively absorbing vibrations and providing excellent anti-interference for the partner. It combines a soft, conforming feel with strong support, effectively promoting spinal health. However, common double-spring mattresses, due to their two layers of springs, tend to be heavier and more difficult to move and install. Therefore, a double-spring mattress design is needed.

[0003] Existing double-spring mattresses are relatively heavy due to their two layers of springs, making them difficult to move and install. Furthermore, the bonding between the two layers relies on adhesives, and if the process is substandard, there is a risk of separation between the layers after prolonged use, affecting overall performance. Additionally, the fixed connection between the two spring layers makes replacement and repair difficult, failing to meet the needs of different users.

[0004] To solve the above problems, after searching, the patent with publication number CN215271674U discloses a double-layer zoned spring mattress and mattress. The article proposes that "(1) by setting five first zones, it is more in line with the application of ergonomics. In addition, by setting the first bed net and the second bed net, the mattress can be used in both directions, with two different sleeping sensations, making the functions more abundant and meeting the needs of different people; (2) by setting independent pocket springs that do not interfere with each other, noise can be effectively reduced, providing a quiet and comfortable sleeping environment, promoting users to fall into deep sleep faster. The Bonnell spring layer has excellent vertical support performance, strong elasticity, and is durable and not easy to collapse; (3) by setting a cotton felt layer, the cotton felt layer not only plays a sound insulation role, but also has a certain cushioning and balancing ability, making the spring mattress feel more natural." Although the mattress can be used in both directions by stacking the first bed net (independent pocket spring layer) and the second bed net (Bonnell spring layer), providing two different sleeping sensations (the quiet and comfortable feeling of independent pocket springs vs. the comfort of independent pocket springs)... Bonnell offers strong support, but adjacent zones are only secured by pegs. Variations in the wire diameter of the individual pocket springs can lead to unnatural transitions in support, resulting in a sagging gradient after long-term use. Furthermore, the mattress has a large difference in firmness between the two sides, requiring users to adjust the mattress orientation when flipping it over, which is a heavy burden for the user.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0006] The purpose of this utility model is to provide a double-layer spring mattress to solve the problems mentioned in the background art. In use, because the existing double-layer spring mattress is composed of two layers of springs, the mattress is relatively heavy and difficult to move and install. At the same time, the connection between the upper and lower layers depends on the adhesive process. If the process is not up to standard, there may be a risk of separation between the layers after long-term use, which will affect the overall performance. In addition, because the upper and lower springs are fixedly connected, it is difficult to replace or repair the upper and lower springs, and it cannot meet the needs of different users.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a double-layer spring mattress, comprising a bottom pad layer, a first side panel attached to the outer surface of the bottom pad layer, a first fixing block attached to the outer surface of the first side panel, plate hooks extending through and rotatably connected to both sides of the first fixing block, a first support layer attached to the upper inner ring surface of the first side panel, a second support layer abutting the upper surface of the first support layer, a second side panel attached to the outer surface of the second support layer, a second fixing block attached to the outer surface of the second side panel, retaining rings extending through and rotatably connected to both sides of the second fixing block, a reinforcing layer attached to the upper surface of the second support layer, a first spring attached to the outer ring of the upper surface of the reinforcing layer, a cloth bag attached to the upper surface of the reinforcing layer, reinforcing ribs fixedly connected to the inner ring surface of the cloth bag, and a second spring abutting the inner ring surface of the cloth bag.

[0008] Preferably, the upper surface of the first support layer has a locking hole, and the lower surface of the second support layer is fixedly connected with a protrusion, wherein the inner ring surface of the locking hole is in close contact with the outer ring surface of the protrusion.

[0009] Preferably, the first fixing block and the second fixing block are arranged vertically, and the plate hook is engaged with the retaining ring.

[0010] Preferably, a third support layer is attached to the upper inner ring surface of the second sidewall, and an anti-slip block is attached to the upper surface of the third support layer.

[0011] Preferably, the upper and lower ends of the inner ring surface of the second side are abutted by the first support rod, and the side of the first support rod is in close contact with the side of the first spring.

[0012] Preferably, the two sets of the first springs are tightly connected vertically by a first vertical locking ring, and the two sets of the first springs are tightly connected laterally by a first transverse locking ring, and the wire diameter of the first spring is 1.8mm.

[0013] Preferably, the reinforcing rib is engaged with the second spring, and the wire diameter of the second spring is 1.2 mm.

[0014] Preferably, the upper surface of the bag cover is sewn with a sewn cover, and the sides of both sets of bag covers are sewn together with connecting fabric.

[0015] Preferably, the upper and lower ends of the inner ring surface of the first side are fitted with a second support rod, and the upper surface of the bottom pad is fitted with a third spring, with the side of the second support rod being tightly connected to the side of the third spring.

[0016] Preferably, the two sets of the third springs are tightly connected vertically by a second vertical locking ring, and the two sets of the third springs are tightly connected laterally by a second transverse locking ring, wherein the wire diameter of the third spring is 2.0 mm.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the double-layer spring bed net, 1. Through the setting of plate hooks, retaining rings and protrusions, during use, the plate hooks and retaining rings can tightly fix the first side and the second side, and the protrusions can tightly fit the first support layer and the second support layer. With the cooperation of the plate hooks, retaining rings and protrusions, a stable fit between the first layer of mattress and the second layer of mattress can be achieved to prevent misalignment. At the same time, it also facilitates the transportation of mattresses and the replacement of upper mattresses with different firmness. 2. Through the design of the first spring, the second spring, the fabric pocket cover, and the reinforcing ribs, the thickened first spring can reinforce the sides of the mattress during use, preventing side collapse. The reinforcing ribs can strengthen the connection between the fabric pocket cover and the second spring, making it easier to replace when the second spring is damaged and increasing the independence of the second spring, thus better meeting the needs of the human body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-7 This utility model provides a technical solution: a double-layer spring mattress, including a bottom pad layer 1, a first side panel 2 attached to the outer surface of the bottom pad layer 1, a first fixing block 3 attached to the outer surface of the first side panel 2, plate hooks 4 connected through and rotatably to both sides of the first fixing block 3, a first support layer 5 attached to the upper inner ring surface of the first side panel 2, a second support layer 6 abutting the upper surface of the first support layer 5, a second side panel 8 attached to the outer surface of the second support layer 6, a second fixing block 9 attached to the outer surface of the second side panel 8, retaining rings 10 connected through and rotatably to both sides of the second fixing block 9, a reinforcing layer 13 attached to the upper surface of the second support layer 6, a first spring 15 attached to the outer ring of the upper surface of the reinforcing layer 13, a cloth bag cover 18 attached to the upper surface of the reinforcing layer 13, a reinforcing rib 19 fixedly connected to the inner ring surface of the cloth bag cover 18, and a second spring 20 abutting the inner ring surface of the cloth bag cover 18.

[0022] Furthermore, a locking hole is provided on the upper surface of the first support layer 5, and a protrusion 7 is fixedly connected to the lower surface of the second support layer 6. The inner ring surface of the locking hole and the outer ring surface of the protrusion 7 are closely fitted. Through the locking hole and the protrusion 7, the first support layer 5 and the second support layer 6 can be quickly and accurately positioned and laterally limited during use. The protrusion 7 is embedded in the locking hole, which effectively prevents the upper and lower support layers from sliding or misaligning relative to each other during use, thereby enhancing the stability of the connection between the bed net layers. At the same time, this plug-in method is also convenient for installation and disassembly.

[0023] Furthermore, the first fixing block 3 and the second fixing block 9 are arranged vertically, and the plate hook 4 is engaged with the retaining ring 10. Through the arrangement of the first fixing block 3, the second fixing block 9, the plate hook 4 and the retaining ring 10, the first side panel 2 and the second side panel 8 can be quickly connected and locked during use. By rotating the plate hook 4 to engage with the retaining ring 10, the first fixing block 3 and the second fixing block 9, which are respectively fixed on the first side panel 2 and the second side panel 8, can be firmly connected together, thereby stably combining the upper and lower layers of the bed net into a whole, and allowing non-destructive separation, which is convenient for transportation and interlayer adjustment.

[0024] Furthermore, a third support layer 11 is attached to the upper inner ring surface of the second side panel 8, and an anti-slip block 12 is attached to the upper surface of the third support layer 11. Through the setting of the third support layer 11 and the anti-slip block 12, additional support can be provided at the edge of the bed net and the surface friction can be increased during use. The third support layer 11 enhances the structural strength of the edge of the bed net and prevents the edge from collapsing, while the anti-slip block 12 can effectively reduce the sliding of the pads or mattresses placed on the bed net due to human movement, ensuring the flatness and stability of the sleeping surface.

[0025] Furthermore, the upper and lower ends of the inner ring surface of the second side 8 are abutted by the first support rod 14. The side of the first support rod 14 is in close contact with the side of the first spring 15. Through the setting of the first support rod 14, the first spring 15 located in the periphery of the bed net can be provided with lateral support and positioning during use. The first support rod 14 abuts against the side of the first spring 15, which can prevent the first spring 15 from excessively displacing or tilting to the side during use, ensuring the stability and shape maintenance of the peripheral spring array, thereby maintaining the support performance of the bed net edge.

[0026] Furthermore, the two sets of first springs 15 are tightly connected vertically via first vertical locking rings 16, and the two sets of first springs 15 are tightly connected laterally via first transverse locking rings 17. The wire diameter of the first spring 15 is 1.8mm. Through the setting of the first vertical locking rings 16 and the first transverse locking rings 17, individual first springs 15 can be connected into a stable whole spring net during use. The locking rings tightly connect adjacent springs in the longitudinal and transverse directions, enabling them to work together and provide uniform and powerful support. The use of thicker springs with a wire diameter of 1.8mm is intended to provide a solid foundation support for the perimeter of the bed net.

[0027] Furthermore, the reinforcing rib 19 engages with the second spring 20, which has a wire diameter of 1.2mm. The reinforcing rib 19 enhances the connection between the bag cover 18 and the second spring 20 during use. The engagement of the reinforcing rib 19 with the second spring 20 effectively secures the second spring 20 within the bag cover 18, preventing the spring from shifting or rotating within the cover and improving the stability of the independent pocket spring unit. At the same time, the thinner spring with a wire diameter of 1.2mm is designed to provide a softer, more intimate cushioning.

[0028] Furthermore, a sewn cover 21 is sewn onto the upper surface of the bag cover 18, and the sides of both sets of bag covers 18 are sewn together by connecting fabric 22. Through the setting of sewn cover 21 and connecting fabric 22, the spring can be encapsulated and each independent spring bag can be connected during use. The sewn cover 21 is used to close the upper opening of the bag cover 18 and encapsulate the second spring 20 inside. The connecting fabric 22 connects each independent bag spring unit into a complete spring layer, ensuring the structural integrity of the entire spring layer while maintaining the independent action of each spring (providing precise support and anti-interference).

[0029] Furthermore, the upper and lower ends of the inner ring surface of the first side panel 2 are both fitted with second support rods 23, and the upper surface of the bottom pad layer 1 is fitted with a third spring 24. The side of the second support rod 23 is closely connected to the side of the third spring 24. Through the setting of the second support rod 23 and the third spring 24, another set of spring support system can be built at the bottom of the bed net during use. The second support rod 23 is used to position and support the third spring 24. The third spring 24 (with a wire diameter of 2.0 mm, the thickest) provides the most basic and solid core support for the bed net, and together with the first spring 15 and the second spring 20, it forms a multi-layered and zoned support system.

[0030] Furthermore, the two sets of third springs 24 are tightly connected vertically via the second vertical locking ring 25, and the two sets of third springs 24 are tightly connected laterally via the second transverse locking ring 26. The wire diameter of the third spring 24 is 2.0mm. Through the setting of the second vertical locking ring 25 and the second transverse locking ring 26, the third springs 24 can be connected into a solid whole spring core during use. The locking rings ensure the integrity and stability of the bottom thick wire diameter spring network, enabling it to withstand the main weight load and provide durable and reliable support, preventing local collapse and extending the service life of the bed net.

[0031] Working principle: The equipment is based on the base layer 1, which is connected to the first fixing block 3 via the first side panel 2. The plate hooks 4 on both sides of the first fixing block 3 can engage with the retaining rings 10 on both sides of the second fixing block 9 on the second side panel 8, realizing the quick and stable connection and convenient separation of the upper and lower bed nets. The interlayer positioning is achieved by the retaining holes on the first support layer 5 and the protrusions 7 on the lower side of the second support layer 6, which fit tightly to prevent misalignment. In terms of the support structure, the outer periphery of the reinforcing layer 13 on the upper side of the second support layer 6 is arranged with a first spring 15 with a wire diameter of 1.8mm. It is connected as a whole by the first vertical locking ring 16 and the first horizontal locking ring 17, and is laterally limited by the first support rod 14, providing strong support for the periphery of the bed net. The upper comfort layer is composed of a cloth bag 18, which is equipped with reinforcing ribs 19 to enhance the connection with the first spring 15 with a wire diameter of 1.2mm. The two springs 20 are engaged and fixed. The top of the bag cover 18 is closed by the sewn cover 21. Adjacent bag covers 18 are connected by connecting fabric 22 to form an independent bag spring layer, providing precise cushioning. The core support of the bottom layer is provided by the third spring 24 with a wire diameter of 2.0mm. It is connected as a whole by the second vertical locking ring 25 and the second horizontal locking ring 26 and positioned by the second support rod 23. Together with the first spring 15 and the second spring 20, it forms a multi-layer support system. The upper end of the second side panel 8 is also provided with a third support layer 11 and an anti-slip block 12 to enhance edge stability and prevent the padding layer from sliding. The overall structure replaces traditional bonding with modular mechanical connection, which solves the problems of easy separation between layers, excessive weight and difficulty in moving and installing, and difficulty in replacing and adjusting the upper and lower layers. It achieves a unity of stable support, convenient disassembly and assembly, and personalized sleeping comfort adjustment.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
