Description

Technical Field

[0001] This invention relates to the field of home mattress technology, and in particular to a modular, glue-free mattress. Background Technology

[0002] Currently, with consumers' increasing awareness of environmental protection and their growing demand for health and safety, the home furnishing industry, especially the mattress sector, is undergoing a profound transformation. Traditional mattresses commonly use glue as an adhesive during the manufacturing process, such as in fixing individually pocketed springs, laminating multiple layers of comfort materials, and installing edge foam. These glues may contain volatile organic compounds (VOCs) such as formaldehyde and benzene, which are slowly released over a long period, affecting indoor air quality, potentially threatening the health of people with respiratory sensitivities, and causing unpleasant chemical odors. Furthermore, glue aging can lead to interlayer delamination or loosening of the overall structure, affecting the mattress's support performance and lifespan, and its use also makes mattress recycling difficult. Therefore, "glue-free" mattresses have emerged as an important industry trend, aiming to eliminate these chemical hazards at the source and meet the market's expectations for more environmentally friendly and healthier sleep products.

[0003] To eliminate the need for glue, the industry has explored various physical fastening technologies. For example, mechanical connections such as zippers, Velcro, staples, stitching (e.g., suture structures), and copper ring fastening are used to replace adhesives, achieving the bonding of mattress top layers, comfort layers, and support layers. Regarding spring cores, ultrasonic welding technology is used to connect individually pocketed springs, replacing traditional hot melt adhesives. At the materials level, new materials such as 4D polymer PE and POE air fibers have been developed, which achieve physical interlocking through a unique three-dimensional network structure, forming a stable whole without glue. These technological solutions have indeed made progress in eliminating the environmental and health hazards associated with glue.

[0004] However, these existing "glue-free" solutions, especially in mattresses that combine multiple materials and rely primarily on physical wrapping and layering, have revealed new technical shortcomings. Due to significant differences in the hardness, density, and elasticity of different materials—for example, when soft latex or memory foam is directly combined with firmer jute, coir, or spring support layers—and subjected to continuous compression and vibration during processing, packaging, and transportation, the layers are prone to relative displacement, collapse, or wrinkling due to a lack of rigid connections or effective constraints. This not only affects the mattress's appearance at the factory but also often requires manual adjustment and repositioning upon arrival at the user's location, severely impacting the unboxing experience and ease of use. More importantly, misalignment and deformation of the material layers directly disrupt the mattress's intended support uniformity and ergonomic design, potentially leading to insufficient localized support or stress concentration, affecting sleep comfort, and even potentially weakening its intended spinal support functions. Therefore, while existing "glue-free" mattresses address basic environmental and health concerns, they still have significant shortcomings in achieving reliable structural stability, ensuring final product quality, and improving user experience.

[0005] In conclusion, the market urgently needs an innovative "zero-glue" mattress structural solution. This solution not only needs to completely eliminate glue bonding, ensuring the product's environmental friendliness and health safety, but also needs to effectively overcome problems such as compression, wrinkling, and deformation caused by differences in material hardness and independence in existing technologies. The goal is to improve the overall structural stability and shape retention of the mattress during processing, transportation, and long-term use, thereby ensuring that the product maintains its excellent shape and intended comfort support performance from the factory to the user's home, ultimately improving user convenience and satisfaction. Summary of the Invention

[0006] The purpose of this invention is to provide a modular, glue-free mattress to solve the problems mentioned in the background art. Through its simple structure, it enables the use of glue-free products and can prevent displacement and wrinkling of internal materials during processing and transportation, thereby improving the environmental performance and stability of the product.

[0007] This invention is achieved through the following scheme: A modular, glue-free mattress includes an inner core structure, a first binding structure, an upper insulating layer, and a lower insulating layer. The upper and lower insulating layers are respectively disposed on the upper and lower sides of the inner core structure. The first binding structure is sleeved on the outside of the inner core structure, the upper insulating layer, and the lower insulating layer. The upper insulating layer is provided with multiple support members, and a second binding structure is provided between adjacent support members.

[0008] Based on the above-mentioned structure of a modular zero-glue mattress, the inner core structure includes a sponge cavity, a support frame, spring sleeves, and spring components; the support frame is arranged around the inner cavity of the sponge cavity, the spring components are arranged in the spring sleeves, the spring sleeves near the support frame are fixedly connected to the support frame, and the spring sleeves away from the support frame are connected to their adjacent spring sleeves; the spring components are arranged in the inner cavity structure of the sponge cavity.

[0009] Based on the structure of the above-mentioned modular zero-glue mattress, the support frame includes a first frame and a second frame, which are arranged vertically parallel to each other. A counter-current steel wire is provided between the first frame and the second frame, and multiple counter-current steel wires are arranged along the circumferential position of the first frame and the second frame.

[0010] Based on the structure of the above-mentioned modular zero-glue mattress, the first frame and the second frame are provided with frame pins, and the frame pins are arranged in multiple ways along the length of the first frame and the second frame. The foam cavity is also provided with a binding strap for fixing the foam cavity, and the binding straps are arranged in multiple ways along the length of the foam cavity. The two ends of the binding straps are respectively fixed to the frame pins on the first frame and the second frame.

[0011] Based on the structure of the above-mentioned modular zero-glue mattress, the first binding structure includes a top quilted cover, a quilted surround cover, and a bottom quilted cover; the upper and lower ends of the quilted surround cover are respectively provided with zipper structures that cooperate with the top quilted cover and the bottom quilted cover.

[0012] Based on the structure of the above-mentioned modular zero-glue mattress, the upper insulating layer includes a sponge pad and a polymer meltblown three-dimensional material pad; the polymer meltblown three-dimensional material pad is disposed between the sponge pad and the inner core structure.

[0013] Based on the above-mentioned structure of a combined glue-free mattress, the second binding structure is an I-shaped glue needle, wherein multiple glue needle holes are discretely arranged on the sponge pad and the polymer meltblown three-dimensional material pad, and the two ends of the I-shaped glue needle pass through the glue needle holes respectively.

[0014] Based on the structure of the above-mentioned combined zero-glue mattress, the I-beam glue pin specifically includes a first limiting post, a second limiting post, and a connecting line; the first limiting post and the second limiting post are arranged in parallel, and the connecting line is arranged between the first limiting post and the second limiting post.

[0015] Based on the structure of the above-mentioned modular zero-glue mattress, the width of the quilted overlay is not less than the height of the foam cavity.

[0016] Based on the structure of the above-mentioned modular zero-glue mattress, the lower insulating layer is specifically a soft cotton felt layer.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This solution uses a second binding structure to fix the upper isolation layer located above the inner liner structure, avoiding wrinkles during processing and transportation. Combined with the binding of the second binding structure on the overall inner liner structure and isolation layer structure, it can achieve the fixation of the overall structure with zero glue. The structure of the entire assembly is simple, and it is relatively easy to process and assemble for ordinary users. Disassembly and maintenance are also relatively simple. Through the use of the assembly, the universal matching of materials can be achieved, while also improving the environmental performance and stability of the product. Attached Figure Description

[0022] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0023] Example 1 like Figures 1-4 As shown, the present invention provides a technical solution: A modular, glue-free mattress includes an inner core structure 1, a first binding structure 2, an upper insulating layer 3, and a lower insulating layer 4. The upper insulating layer 3 and the lower insulating layer 4 are respectively disposed on the upper and lower sides of the inner core structure 1. The first binding structure 2 is sleeved on the outside of the inner core structure 1, the upper insulating layer 3, and the lower insulating layer 4. The upper insulating layer 3 is provided with multiple layers of support members, and a second binding structure is provided between adjacent support members.

[0024] Based on the above structure, this solution uses a second binding structure to fix the upper isolation layer 3 located above the inner liner structure 1, avoiding wrinkles during processing and transportation. With the binding of the second binding structure on the overall inner liner structure 1 and the isolation layer structure, it is possible to achieve fixation of the overall structure without the use of glue. The structure of the entire assembly is simple, and for ordinary users, processing and assembly are relatively simple, and disassembly and maintenance are also relatively simple. Through the use of the assembly, the universal matching of materials can be achieved, while also improving the environmental performance and stability of the product.

[0025] As an example, the inner liner structure 1 may include a sponge cavity 11, a support frame 12, a spring sleeve 13, and a spring member 14; the support frame 12 is arranged around the inner cavity of the sponge cavity 11, the spring member 14 is disposed in the spring sleeve 13, the spring sleeve 13 near the support frame 12 is fixedly connected to the support frame 12, and the spring sleeve 13 away from the support frame 12 is connected to its adjacent spring sleeve 13; the spring member 14 is disposed in the inner cavity structure of the sponge cavity 11.

[0026] Based on the above structure, the support frame 12 restricts the boundary of the spring element 14 and supports the spring sleeve 13, so that all the spring elements 14 are confined within a predetermined area. The sponge cavity 11 surrounds the entire side of the support frame 12, making it more comfortable for the human body to use.

[0027] As an example, the support frame 12 may include a first frame 121 and a second frame 122, which are arranged vertically parallel to each other. A counter-current steel wire 123 may be provided between the first frame 121 and the second frame 122, and multiple counter-current steel wires 123 may be provided at circumferential positions along the first frame 121 and the second frame 122.

[0028] Based on the above structure, the first frame 121 and the second frame 122 are complete rectangular frames that serve as supports. The anti-rebound steel wires 123 are set at certain intervals and have a certain elastic contraction function.

[0029] As an example, scaffolding studs 124 can be provided on the first frame 121 and the second frame 122. Multiple scaffolding studs 124 are provided along the length of the first frame 121 and the second frame 122. A restraint strap 125 for fixing the sponge cavity 11 can also be provided on the sponge cavity 11. Multiple restraint straps 125 are provided at intervals along the length of the sponge cavity 11. The two ends of the restraint strap 125 are respectively fixed to the scaffolding studs 124 on the first frame 121 and the second frame 122.

[0030] Based on the above structure, in this solution, the sponge cavity 11 is fixed to the first frame 121 and the second frame by the binding strap 125. No glue is needed throughout the process, which can achieve efficient fixation of the sponge cavity 11.

[0031] As an example, the first binding structure 2 may include a top quilted cover 21, a quilted girdle cover 22, and a bottom quilted cover 23; the upper and lower ends of the quilted girdle cover 22 are respectively provided with zipper structures that cooperate with the top quilted cover 21 and the bottom quilted cover 23.

[0032] The width of the quilted cover 22 is not less than the height of the sponge cavity 11, so that the quilted cover 22 can wrap the sponge cavity 11.

[0033] Based on the above structure, the top quilted cover 21, the quilted girder cover 22 and the bottom quilted cover 23 are connected as a whole by a zipper structure to achieve the fixation of the entire bed structure.

[0034] As an example, the upper isolation layer 3 may include a sponge pad 31 and a polymer meltblown three-dimensional material pad 32; the polymer meltblown three-dimensional material pad 32 is disposed between the sponge pad 31 and the inner liner structure 1; The second binding structure can be an I-shaped glue needle, with multiple glue needle holes discretely arranged on the sponge pad 31 and the polymer meltblown three-dimensional material pad 32, and the two ends of the I-shaped glue needle passing through the glue needle holes respectively.

[0035] Based on the above structure, this solution uses discretely arranged I-beam adhesive to fix the sponge pad 31 and the polymer meltblown three-dimensional material pad 32, so that they can maintain the stability between adjacent layers after transportation and extrusion, while avoiding the use of glue.

[0036] As an example, the I-shaped adhesive needle can specifically include a first limiting post 51, a second limiting post 52, and a connecting line 53; the first limiting post 51 and the second limiting post 52 are arranged in parallel, and the connecting line 53 is arranged between the first limiting post 51 and the second limiting post 52.

[0037] Based on the above structure, the positions of the sponge pad 31 and the polymer meltblown three-dimensional material pad 32 can be restricted by the first limiting post 51 and the second limiting post 52, thereby fixing the material and preventing the material from shifting.

[0038] As an example, the lower insulating layer 4 can specifically be a soft cotton felt layer, which can prevent the spring layer from directly contacting the bottom quilted fabric.

[0039] Example 2 This invention provides a technical solution: A modular, glue-free mattress includes an inner core composed of a four-leaf clover spring and foam; the upper padding layer of the inner core uses a combination of foam and high-polymer meltblown three-dimensional material, which is connected by I-beam adhesive pins; the surface and bottom are provided with independently quilted washable covers, which are connected to a washable mattress quilted overlay cover 22 by zippers to realize the assembly of the entire product.

[0040] The mattress inner core is composed of clover-shaped springs and foam. The inner core is composed of springs covered with a fabric cover, which are combined and positioned by upper and lower frame steel wires. The upper and lower frame steel wires are then supported by anti-rebound steel wires 123 and fixed to the frame steel wires by staples, which play a supporting role and form an internal spring mesh.

[0041] The inner spring mesh is surrounded by a sponge layer. The sponge layer is made of a certain width of fabric and is locked to the steel wire at the top and bottom ends by mattress frame steel wire nails, which serves to stabilize the surrounding sponge and form the sponge and spring mesh inner core.

[0042] The inner liner of the sponge and spring mesh is covered with a fabric layer on the outside. The upper and lower ends of the fabric layer are fixed to the steel wire of the frame by staples, which covers the internal material and plays a role in sound insulation and wear prevention.

[0043] The inner liner is padded with a combination of sponge and polymer meltblown three-dimensional material, which are connected by I-beam adhesive pins.

[0044] The two ends of the I-shaped adhesive needle are horizontally cylindrical, and the middle is connected by a linear shape, which can fix the material and prevent the material from shifting.

[0045] The surface and bottom are provided with independently quilted washable covers, which are combined and connected with washable mattress quilted cover 22 by means of zippers to realize the combination of the whole product.

[0046] The washable face cover is made of fabric and washable cotton quilting, and can be washed. It is assembled with a zipper and a mattress quilted cover 22 after being sewn around the perimeter to form the product.

[0047] The mattress quilted cover 22 is made of fabric and washed cotton quilting, and can be washed. It is connected to the cover by a zipper to complete the assembly of the entire product.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
