Description

Technical Field

[0001] The utility model relates to the field of bedding, in particular to a glue-free mattress. Background Art

[0002] Existing mattresses contain glue, primarily in three locations: 1. The core (primarily pocket springs), which is bonded together with hot-melt adhesive (adjacent pocket springs are connected by glue); 2. The multi-layered comfort layer (using multiple comfort layers improves comfort), which is typically secured with a spray-on adhesive process; and 3. The raw materials (comfort layer and cover) themselves contain glue. These mattresses are environmentally unfriendly, emit formaldehyde, volatile compounds, have an unpleasant odor, and are noisy, posing safety risks to sleep. Furthermore, during disassembly, the glued materials can break easily, resulting in a low recycling rate.

[0003] In addition, the existing mattresses have a single support hardness on the same usage surface, and the support provided by the mattress from top to bottom is the same, either harder or softer, without soft and hard support levels, which has a poor support effect on the body and affects the user's rest and sleep quality. Summary of the Invention

[0004] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art and to provide a glue-free mattress. The comfort layer is fixed to the bed core by a surface layer, and the surface layer is fixed to the bed core by a glue-free connection structure, so as to form a glue-free mattress. It is beneficial to the health of the user, keeps the air around the mattress fresh, and is also convenient for the mattress to be disassembled and recycled for reuse. Moreover, at least one support layer on the comfort layer has several support sections with different hardness, which can form appropriate support force and support surface that fits the body curve for different body parts of the user, which is conducive to the user's more relaxed rest and sleep, thereby achieving the purpose of improving the user's rest and sleep quality.

[0005] The above technical objectives of the present invention are mainly solved through the following technical solutions: a glue-free mattress, comprising a bed core, a comfort layer covering the surface of the bed core, and a surface layer wrapping the bed core and the comfort layer, characterized in that the surface layer is connected to the bed core through a connecting structure, the comfort layer is fixed to at least one surface of the bed core through the surface layer, the comfort layer on the same side of the bed core comprises a first support layer, a second support layer and a third support layer, wherein at least one support layer has several support sections with different hardness, which are used to enable sections with corresponding hardness to support corresponding body parts of the user.

[0006] In this technical solution, the comfort layer is fixed to the bed core through the surface layer, and the surface layer is fixed to the bed core through a glue-free connection structure, forming a glue-free mattress, which is beneficial to the user's health, keeps the air around the mattress fresh, and is also conducive to the disassembly, recycling and reuse of the mattress.

[0007] At the same time, the comfort layer has several support sections with different hardness. When using the mattress, the comfort layer is deformed by the pressure of different parts of the user's body, and can form appropriate support force and a support surface that fits the body curve for different parts of the user's body, which is conducive to the user's more relaxed rest and sleep, thereby achieving the purpose of improving the user's rest and sleep quality.

[0008] In addition, the hardness and material of the first support layer, the second support layer and the third support layer can be independently selected according to actual conditions to form a rich support effect, which is more suitable for the corresponding users and further helps to improve the user's rest and sleep quality.

[0009] As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures: the first support layer is a 3D mesh layer, the second support layer is a latex layer, and the third support layer is a sponge layer. Of course, the hardness and material of the first, second, and third support layers are not limited to the 3D mesh, latex, sponge, etc. selected in this technical solution. The first, second, and third support layers can be independently selected according to actual conditions to achieve a rich support effect that is more suitable for the corresponding user, further helping to improve the user's rest and sleep quality.

[0010] Preferably, along the length of the bed core, the first support layer includes a first-layer central support section, first-layer middle support sections located at both ends of the first-layer central support section, and first-layer end support sections respectively cooperating with both ends of the bed core. The hardness of the first-layer central support section, the first-layer middle support section, and the first-layer end support sections decrease in sequence. The first support layer forms five sections with rich soft and hard support effects, respectively supporting the head and neck, back, waist, buttocks, and legs of the human body. When the user lies on the mattress, each area of ​​the first support layer is subjected to the force of the corresponding body part, forming a curved surface that fits the curve of the human body and providing appropriate support force to each body part, thereby helping to improve the user's rest and sleep quality.

[0011] Preferably, the outer side of the second support layer is provided with at least two spaced-apart second-layer slits, forming a three-part support layer with differentiated hardness. Similar to the principle of providing individual support segments in the first support layer, the second support layer is preferably formed into three-part support segments by providing slits. Each segment of the second support layer overlaps with the corresponding segment of the first support layer, enabling the comfort layer to better support various parts of the user's body, forming a curved surface that better conforms to the body's curves, thereby further improving the user's rest and sleep quality.

[0012] Preferably, each second-layer slit region is provided with a plurality of second-layer slits, each of which is spaced parallel to and spaced apart from the width of the mattress core. Each second-layer slit has a rectangular cross-section, and the depth of each second-layer slit is less than the thickness of the second support layer. The shape and depth of the second-layer slits can better balance the pressure exerted by the user's body on the comfort layer, allowing each section of the first and second support layers to form appropriate deformations to better conform to the body's curves, thereby further ensuring the user's rest and sleep quality.

[0013] Preferably, a plurality of third-layer cutting seams are provided on the inner side of the third support layer along the length direction of the bed core, and each of the third-layer cutting seams is provided in parallel and spaced apart along the width direction of the bed core. The third-layer cutting seams are symmetrically provided along the length direction of the bed core with the center line of the bed core as the symmetry line, and the cross-sectional area of ​​the third-layer cutting seams on one side of the symmetry line gradually increases and then gradually decreases, and so on. The cutting seams on the third support layer are used to change the deformation capacity and support strength of the corresponding positions of the third support layer. The third support layer with cutting seams is overlapped with the first support layer and the second support layer, so that the support force and deformation effect of each part of the comfort layer are more compatible with the user's body, providing more appropriate support force for each part of the user's body, and being able to better overlap with the human body curve, which can better improve the user's rest and sleep quality.

[0014] Preferably, a fixing structure is provided around the periphery of the comfort layer, extending back and forth through the comfort layer to connect the multiple layers of the comfort layer. The fixing structure is a suture. The fixing structure serves to secure the layers of the comfort layer, preventing them from shifting and ensuring comfort. Furthermore, the fixing structure ensures that the mattress is glue-free, ensuring safety, and facilitating the recycling of used mattresses, contributing to environmental protection and energy conservation.

[0015] Preferably, the connection structure includes a handle cloth strip arranged on the inner side of the surface layer, and a connector. The handle cloth strip is arranged corresponding to the side of the bed core, and the handle cloth strip is fixed to the side of the bed core through the connector. The handle cloth strip is at least two cloth strips spaced apart from each other, and the handle cloth strips are fixed to the side of the bed core through nails. The connection structure using handle cloth strips and connectors is used to ensure that the mattress is glue-free, which is beneficial to ensuring the safety of the mattress, and is also beneficial to the recycling and reuse of old mattresses, which is environmentally friendly and energy-saving. Providing at least two cloth strips spaced apart from each other is beneficial to improving the reliability of the surface layer fixation, ensuring that the surface layer and the comfort layer can be stably limited on the bed core during the transportation and displacement of the mattress, thereby ensuring the quality and reliability of the mattress.

[0016] Preferably, the mattress core comprises multiple pocket springs or a Bonnier spring core, with adjacent pocket springs connected by ultrasonic welding. The individual springs are housed in separate pockets, and the core formed by ultrasonic welding of adjacent pockets, as well as the Bonnier spring core, are glue-free, further ensuring a glue-free mattress that is both safe to use and easily recyclable.

[0017] The beneficial effects of the present invention are as follows: the comfort layer is fixed to the bed core by the surface layer, and the surface layer is fixed to the bed core by a glue-free connection structure, thereby forming a glue-free mattress, which is beneficial to the user's health, keeps the air around the mattress fresh, and is also beneficial to the disassembly and recycling of the mattress. Moreover, the first support layer, the second support layer and the third support layer on the comfort layer can form rich and detailed support force differentiation and form a support surface that completely fits the user's body curve through corresponding cutting seam settings or material hardness settings, thereby meeting the needs of more different users and ensuring that all users can get better relaxation, rest and sleep quality.

[0024] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0025] Example: Figure 1-Figure 5 As shown, a glue-free mattress includes a bed core 1, a comfort layer 2 covering the surface of the bed core 1, and a surface layer wrapping the bed core 1 and the comfort layer 2.

[0026] The difference between this technical solution and the existing technology is that: the surface layer is connected to the bed core 1 through a connecting structure, the comfort layer 2 is fixed to at least one surface of the bed core 1 through the surface layer, and the comfort layer 2 on the same surface of the bed core 1 includes a first support layer 9, a second support layer 10 and a third support layer 11, wherein at least one support layer has several support sections with different hardness, which are used to enable sections with corresponding hardness to support corresponding body parts of the user.

[0027] In this technical solution, the comfort layer 2 is fixed to the bed core 1 through the surface layer, and the surface layer is fixed to the bed core 1 through a glue-free connection structure, forming a glue-free mattress, which is beneficial to the user's health, keeps the air around the mattress fresh, and is also conducive to the disassembly, recycling and reuse of the mattress.

[0028] In this technical solution, the comfort layer 2 has several support sections with different hardness. When the mattress is used, the comfort layer 2 is deformed by the pressure of different parts of the user's body, and can form appropriate support force and a support surface that fits the body curve for different parts of the user's body, which is conducive to the user's more relaxed rest and sleep, thereby achieving the purpose of improving the user's rest and sleep quality.

[0029] In this technical solution, the hardness and material of the first support layer 9, the second support layer 10 and the third support layer 11 can be independently selected according to actual conditions to form a rich support effect, which is more suitable for the corresponding users and further helps to improve the user's rest and sleep quality.

[0030] Next, further improve the above technical solution:

[0031] In actual application, the comfort layer 2 is arranged on one side of the bed core 1 or on two opposite sides of the bed core 1 , and the comfort layer 2 is fixed to the bed core 1 through a surface layer.

[0032] In practical applications, the first supporting layer 9 is a 3D mesh layer, the second supporting layer 10 is a latex layer, and the third supporting layer 11 is a sponge layer.

[0033] Of course, in actual applications, the hardness and materials of the first support layer 9, the second support layer 10 and the third support layer 11 are not limited to the 3D mesh, latex, sponge and other materials selected in this technical solution. The first support layer 9, the second support layer 10 and the third support layer 11 can be independently selected according to actual conditions to form a rich support effect, which is more suitable for the corresponding user, and further helps to improve the user's rest and sleep quality.

[0034] In actual use, along the length of the bed core 1, the first support layer 9 includes a first-layer central support section 13, a first-layer middle support section 14 located at both ends of the first-layer central support section 13, and a first-layer end support section 15 respectively cooperating with both ends of the bed core 1. The hardness of the first-layer central support section 13, the hardness of the first-layer middle support section 14, and the hardness of the first-layer end support section 15 decrease in sequence. The first support layer 9 forms five sections with rich soft and hard support effects, which are used to support the head and neck, back, waist, buttocks, and legs of the human body respectively. When the user lies on the mattress, each area of ​​the first support layer 9 is subjected to the force of the corresponding part of the human body, forming a curved surface that fits the curve of the human body and providing appropriate support force to each part, thereby helping to improve the user's rest and sleep quality.

[0035] In practice, the outer side of the second support layer 10 is provided with at least two spaced-apart second-layer slit regions 16, forming a three-part support layer with differentiated hardness. Similar to the principle of providing individual support segments in the first support layer 9, the second support layer 10 is preferably formed into three-part support segments by providing slits. Each segment of the second support layer 10 overlaps with the corresponding segment of the first support layer 9, enabling the comfort layer 2 to better support various parts of the user's body, forming a curved surface that better conforms to the body's curves, thereby further improving the user's rest and sleep quality.

[0036] In practice, each second-layer slit region 16 is provided with a plurality of second-layer slits 17 . Each second-layer slit 17 is spaced parallel to and spaced apart from each other along the width of the bed core 1 . Each second-layer slit 17 has a rectangular cross-section, and its depth is less than the thickness of the second support layer 10 . The shape and depth of the second-layer slits 17 better balance the pressure exerted by the user's body on the comfort layer 2 , allowing each section of the first support layer 9 and the second support layer 10 to deform appropriately, better conforming to the body's curves and ensuring a better rest and sleep quality for the user.

[0037] In actual application, a plurality of third-layer cutting seams 18 are provided on the inner side of the third support layer 11 along the length direction of the bed core 1. Each of the third-layer cutting seams 18 is provided in parallel and spaced apart along the width direction of the bed core 1. The third-layer cutting seams 18 are symmetrically provided along the length direction of the bed core 1 with the center line of the bed core 1 as the symmetry line. The cross-sectional area of ​​the third-layer cutting seams 18 on one side of the symmetry line gradually increases and then gradually decreases, and so on. The cutting seams on the third support layer 11 are used to change the deformation ability and support strength of the corresponding positions of the third support layer 11. The third support layer 11 with the cutting seams is overlapped with the first support layer 9 and the second support layer 10, so that the support force and deformation effect of each part of the comfort layer 2 are more compatible with the user's body, providing more appropriate support for each part of the user's body, and being able to better overlap with the human body curve, which can better improve the user's rest and sleep quality.

[0038] In actual use, a fixing structure 8 is provided around the periphery of the comfort layer 2. The fixing structure 8 extends back and forth through the comfort layer 2 to connect the multiple layers of the comfort layer 2. The fixing structure 8 serves as a suture. The fixing structure 8 serves to secure the various layers of the comfort layer 2, preventing them from shifting and ensuring user comfort. Furthermore, the use of the fixing structure 8 ensures that the mattress is glue-free, ensuring safety, and facilitating the recycling of used mattresses, thereby contributing to environmental protection and energy conservation.

[0039] The surface layer in this technical solution is connected without glue, which can effectively avoid the generation of abnormal noise (due to the different hardness of the glue after curing and the hardness of the surface layer, during use, the displacement of the cured glue and the surface layer caused by the pressure and movement of the user is different, and they are prone to rubbing against each other to produce abnormal noise), which is conducive to ensuring a quiet use environment and improving the quality of rest and sleep of users using the mattress.

[0040] In this technical solution, the surface layer is connected without glue, which is convenient for disassembly, reduces or even avoids destructive disassembly of the surface layer, comfort layer 2, bed core 1 and other structures, is conducive to the disassembly, recycling and reuse of the mattress, and is conducive to energy conservation and emission reduction.

[0041] In practical applications, the fixing structure 8 is preferably a cotton thread sewn structure formed by sewing the comfort layer 2 with cotton thread pulled by a steel needle.

[0042] In actual application, the connection structure includes a handle strip 3 arranged on the inner side of the surface layer, and a connector 4. The handle strip 3 is arranged corresponding to the side of the bed core 1, and the handle strip 3 is fixed to the side of the bed core 1 through the connector 4.

[0043] The connection structure, using a handle strip 3 and connector 4, ensures that the mattress is glue-free, which helps ensure mattress safety, facilitates the recycling of old mattresses, and promotes environmental protection and energy conservation. The provision of at least two strips of fabric spaced apart above and below helps improve the reliability of the surface layer, ensuring that the surface layer and comfort layer 2 can be stably fixed to the mattress core 1 during transportation and relocation, thereby ensuring the quality and reliability of the mattress.

[0044] In actual application, the handle strip 3 is fixed to the side of the bed core 1 by means of nails (i.e., the connecting member 4 is preferably a nail). The use of nails does not require glue and is highly efficient in the fixing process. In addition, it is also convenient for disassembly and reduces the destructive effects of nail removal.

[0045] In actual use, in order to improve the fixing reliability and prevent the surface layer and comfort layer 2 from shifting during transportation of the mattress, the handle strips 3 are at least two strips of cloth spaced apart from each other, and the handle strips 3 are fixed to the side of the bed core 11 by means of nails. The handle strips 3 are fixed to the side wall of the bed core 1, which facilitates the fixing or removal operation and helps improve the operating efficiency.

[0046] The surface layer (the comfort layer 2 is constrained by the surface layer and fixed to the bed core 1) is fixed to the side wall of the bed core 1 by the handle strip 3, which is convenient for fixing or removing operations and is conducive to improving operating efficiency. The handle strip 3 is set on the side, which is also conducive to improving the comfort of using the mattress.

[0047] In actual application, the surface layer includes an upper layer 5, a lower layer 6 and a surrounding surface layer. The edge of the upper layer 5 is sewn to the upper edge of the surrounding surface layer, and the lower edge of the surrounding surface layer is connected to the edge of the lower layer 6 by a zipper. The surface layer is a fabric layer, or the surface layer includes a fabric layer for the face and a flexible elastic layer quilted and composited to the inner surface of the fabric layer.

[0048] The top layer 5, bottom layer 6, and surrounding surface layer form a fully enclosed structure, which helps improve the overall quality and visual effect of the mattress. The various parts are connected by glue-free stitching and zipper closures. The handle fabric is sewn to the top layer 5 or bottom layer 6 through zipper closures, further ensuring that the mattress is glue-free.

[0049] In actual use, the mattress core 1 is a plurality of independently pocketed springs or a Bonnier spring core, with adjacent independently pocketed springs connected by ultrasonic welding. The independently pocketed springs are housed in separate fabric pockets, and the fabric core 1 and Bonnier spring core 1 are both glue-free, further ensuring a glue-free mattress that is both safe to use and easily recyclable.

[0050] In this technical solution, all parts of the mattress, such as the comfort layer 2 and the surface layer, are made of glue-free raw materials, which is conducive to ensuring that all parts of the mattress are free of glue, eliminating the presence of glue inside the mattress, and preventing the harmful gas generated by the decomposition of the internal glue over time from overflowing and affecting the health of use, thereby ensuring the overall health of the mattress.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations are possible in the above embodiments. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
