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, the glue-connected materials are easily damaged during disassembly, resulting in a low recycling rate.
[0003] Moreover, the existing mattress has the same support hardness across the entire use surface, and when in use, it produces the same support force on all parts of the user's body, making it difficult to form a curve that fits all parts of the body. The support effect on the body is poor, affecting 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 connecting 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, recycled and reused. Moreover, the comfort layer has several support sections with different hardness. When the mattress is used, the comfort layer is deformed by the pressure of different body parts of the user, and 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 to rest and sleep more relaxedly, thereby achieving the purpose of improving the rest and sleep quality of the user.
[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, and the comfort layer has several support sections with different hardness, which are used to enable sections with different hardness to support different body parts of the user.
[0006] In this technical solution, all components of the mattress, including the comfort layer and the surface layer, are made of glue-free raw materials. Furthermore, the comfort layer is secured to the mattress core via the surface layer, which is in turn secured to the mattress core via a glue-free connection structure, creating a glue-free mattress. This improves the user's health, maintains a fresh air odor around the mattress, and facilitates mattress disassembly and recycling. Furthermore, the comfort layer has several support sections of varying hardness. When the mattress is in use, the comfort layer deforms under pressure from different parts of the user's body, creating appropriate support and a support surface that conforms to the user's body curves. This facilitates a more relaxed rest and sleep, thereby improving the user's rest and sleep quality.
[0007] As a further improvement and supplement to the above technical solution, the present invention employs the following technical measures: the comfort layer, disposed on the same surface of the bed core, comprises a first sponge layer on the outside and a second sponge layer on the inside of the first sponge layer, wherein the first sponge layer has a lower hardness than the second sponge layer. By providing a two-layer comfort layer with different hardnesses, the comfort layer can provide a more comfortable support effect.
[0008] Preferably, each of the first and second sponge layers is provided with at least one slit region, with the slit openings of the slit regions being arranged opposite each other. The provision of the slit regions facilitates different hardness zones in the comfort layer along the length of the mattress. When a user lies on the mattress, the comfort layer with different hardness zones can provide appropriate hardness support for different parts of the user's body, thereby providing the user with a more comfortable and supportive experience.
[0009] Preferably, the first sponge layer and the second sponge layer are respectively provided with three first cutting seam areas and three second cutting seam areas at intervals. The three first cutting seam areas are respectively provided at two positions near the two ends of the length direction of the bed core, and one first cutting seam area is provided between the two first cutting seam areas; the three second cutting seam areas include two positions near the two ends of the length direction of the bed core, and one second cutting seam area is provided between the two second cutting seam areas. The first sponge layer and the second sponge layer respectively form three spaced support sections with differentiated hardness through the provision of the first cutting seam areas and the second cutting seam areas (since the three cutting areas are provided continuously, they can be regarded as one area, plus the two areas at both ends of the cutting areas). In addition, the first cutting seam areas on the first sponge layer and the second cutting seam areas on the second sponge layer can be provided in a one-to-one correspondence or staggered arrangement, and can form a rich support hardness differentiation, can better adapt to the human body structure, and improve a more comfortable support effect.
[0010] Preferably, two sections of the first cutting seam area and two sections of the second cutting seam area are arranged near the two ends in the length direction of the bed core, and each cutting seam area has a plurality of cutting seams. The cutting seams of each cutting seam area are arranged along the width direction of the bed core, and the cutting seams are parallel and spaced apart. The cross-sectional dimensions of the cutting seams gradually change from small to large and then from large to small from one end of the bed core toward the other end of the bed core. Of course, the cross-sectional dimensions of the cutting seams can also be appropriately changed according to actual conditions. They can be the same size or randomly arranged in random sizes. These technical solutions also fall within the scope of the present invention.
[0011] Preferably, a section of the first cutting seam area and a section of the second cutting seam area provided in the middle area of the bed core are respectively provided in a one-to-one correspondence, and the first cutting seam area and the second cutting seam area provided in the middle area of the bed core are both a plurality of cutting seams in a uniform wavy shape, and the cutting seams of the first cutting seam area and the cutting seams of the second cutting seam area are interlocked in a yin-yang manner. The yin-yang interlocking is conducive to preventing the first sponge layer and the second sponge layer from shifting relative to each other, so that the first sponge layer and the second sponge layer form a stable matching relationship, which is conducive to ensuring the comfort of the mattress, ensuring that each cutting seam area can support the appropriate part of the user's body, and ensuring the comfort of the mattress.
[0012] Preferably, the comfort layer is disposed on one side of the mattress core or on two opposing sides of the mattress core, and is secured to the mattress core via a surface layer. The securing structure penetrates the comfort layer back and forth, thereby connecting the multi-layered comfort layers. To ensure a stable fit and prevent displacement of the multi-layered comfort layers, a glue-free, back-and-forth securing structure is employed. The securing structure penetrates back and forth, thereby connecting the multi-layered comfort layers. The use of the securing structure further ensures that the mattress is glue-free.
[0013] Preferably, the connection structure includes a handle strip provided on the inner side of the surface layer, and a connector. The handle strip is provided corresponding to the side of the bed core, and the handle strip is fixed to the side of the bed core via the connector. The comfort layer is fixed to the bed core via the surface layer, and the surface layer is fixed to the bed core via the handle strip and the connector, so that the comfort layer and the surface layer are fixed without glue, and at least the outer structure of the mattress is a glue-free structure, which helps to avoid the decomposition and overflow of harmful substances in the glue that affect the user's health and the odor of the air surrounding the mattress, ensuring that the mattress is healthy to use and the air in the environment is fresh. At the same time, due to the glue-free connection, abnormal noises can be avoided, which helps to ensure a quiet use environment and improve the quality of rest and sleep for users using the mattress. In addition, the glue-free connection facilitates disassembly, reduces or even avoids destructive disassembly of structures such as the surface layer, comfort layer, and bed core, facilitates the disassembly, recycling, and reuse of the mattress, and helps to save energy and reduce emissions.
[0014] Preferably, the handle strips comprise at least two strips spaced apart in a vertical arrangement, secured to the side of the mattress core using a staple gun. Securing the handle strips to the side walls of the mattress core facilitates both mounting and removal, improving operational efficiency. The two strips spaced apart in a vertical arrangement enhance securement and prevent displacement of the mattress's top and comfort layers during transport, ensuring their stable positioning on the mattress.
[0015] 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.
[0016] The beneficial effects of the present invention are as follows: 1. 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 beneficial to the disassembly and recycling of the mattress. 2. The comfort layer has several support sections with different hardness. When the mattress is used, the comfort layer is deformed by the pressure of different parts of the user's body, and can form a suitable support force and a support surface that fits the body curve for different parts of the user's body, which is beneficial for the user to rest and sleep more relaxedly, thereby achieving the purpose of improving the user's rest and sleep quality. 3. All structures of the mattress are connected or fixed by a glue-free connection structure or a fixed structure, and all parts of the mattress are made of glue-free raw materials, so that the mattress as a whole is a glue-free mattress, ensuring that the mattress is healthy to use and convenient to disassemble, recycle and reuse.

[0023] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.
[0024] 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.
[0025] 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 has several support sections with different hardness, which are used to enable sections with different hardness to support different body parts of the user.
[0026] First, in this technical solution, all parts of the mattress, such as the comfort layer 2 and the surface layer, are made of raw materials without glue.
[0027] Then, 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] At the same time, 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] Further improvement and supplement to the above technical solutions:
[0030] In actual application, the comfort layer 2 disposed on the same surface of the bed core 1 includes a first sponge layer 9 on the outside and a second sponge layer 10 disposed on the inside of the first sponge layer 9. The hardness of the first sponge layer 9 is lower than that of the second sponge layer 10. By providing a two-layer structure of the comfort layer 2 with different hardnesses, the comfort layer 2 can provide a more comfortable support effect.
[0031] During use, the user first contacts the first sponge layer 9 with lower hardness, and the user can feel the soft and comfortable contact sensation. When the user lies completely on the mattress, the first sponge layer 9 can better wrap the body, and the second sponge layer 10 is harder and can provide better support for the body, so that the user can have better comfort from contacting the mattress to finishing lying on the mattress.
[0032] In practice, each of the first and second sponge layers 9, 10 is provided with at least one slit region, with the cutout openings of the slit regions of the first and second sponge layers 9, 10 positioned opposite each other. The provision of the slit regions facilitates different hardness zones in the comfort layer 2 along the length of the mattress. When a user lies on the mattress, the comfort layer 2 with its different hardness zones can provide appropriate hardness support for different body parts, thereby providing a more comfortable and supportive experience for the user.
[0033] In actual application, three sections of first cutting seam areas 11 and three sections of second cutting seam areas 12 are respectively arranged on the first sponge layer 9 and the second sponge layer 10. The three sections of the first cutting seam areas 11 are respectively arranged at two sections of the first cutting seam areas 11 close to the two ends in the length direction of the bed core 1, and one section of the first cutting seam area 11 is arranged between the two sections of the first cutting seam areas 11; the three sections of the second cutting seam areas 12 include two sections of the second cutting seam areas 12 close to the two ends in the length direction of the bed core 1, and one section of the second cutting seam area 12 is arranged between the two sections of the second cutting seam areas 12.
[0034] The first sponge layer 9 and the second sponge layer 10 are respectively provided with the first cutting seam area 11 and the second cutting seam area 12 to form three spaced support sections with different hardness.
[0035] In addition, the first cutting seam area 11 on the first sponge layer 9 and the second cutting seam area 12 on the second sponge layer 10 can be set in a one-to-one correspondence or staggered arrangement, and can form a rich support hardness distinction, can better adapt to the human body structure, and improve a more comfortable support effect.
[0036] In actual application, two sections of the first cutting seam area 11 and two sections of the second cutting seam area 12 are arranged near the two ends in the length direction of the bed core 1, and each cutting seam area has a plurality of cutting seams. The cutting seams in each cutting seam area are arranged along the width direction of the bed core 1, and the cutting seams are parallel and spaced apart. The cross-sectional size of the cutting seam gradually changes from small to large and then from large to small from one end of the bed core 1 toward the other end of the bed core 1.
[0037] Of course, the cross-sectional dimensions of the cutting seams can also be appropriately changed according to actual conditions. They can be of the same size or randomly arranged in random sizes. These technical solutions also fall within the scope of the present invention.
[0038] In actual application, a section of the first cutting seam area 11 and a section of the second cutting seam area 12 arranged in the middle area of the bed core 1 are respectively arranged in one-to-one correspondence, and the first cutting seam area 11 and the second cutting seam area 12 arranged in the middle area of the bed core 1 are both several uniformly wavy cutting seams, and the cutting seams of the first cutting seam area 11 and the cutting seams of the second cutting seam area 12 are yin-yang fitted together.
[0039] This technical solution prevents the first sponge layer 9 and the second sponge layer 10 from shifting relative to each other through the yin-yang interlocking, so that the first sponge layer 9 and the second sponge layer 10 form a stable matching relationship, which is conducive to ensuring the comfort of using the mattress, ensuring that each cutting seam area can support the appropriate part of the user's body, and ensuring the comfort of using the mattress.
[0040] 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.
[0041] In practical applications, to ensure a stable fit and prevent displacement of the multi-layered comfort layer 2, 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, connecting the multi-layered comfort layer 2. The fixing structure 8 is secured by the glue-free, back-and-forth penetrating fixing structure 8. The fixing structure 8 further ensures that the mattress is glue-free.
[0042] 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.
[0043] In practical applications, a third layer structure may be provided inside the second sponge layer 10 of the comfort layer 2. The material of the third layer structure is at least one of latex, sponge, and 3D mesh. The third layer structure may be a single layer structure or a multi-layer structure of at least two layers. Whether the third layer structure is required depends on actual design requirements or usage requirements. When the third layer structure is a multi-layer structure, the materials of each third layer structure may be the same or different.
[0044] 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.
[0045] 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 the handle cloth strip 3 and the connecting piece 4, so that the comfort layer 2 and the surface layer are fixed without glue, and at least the outer structure of the mattress is a glue-free structure, which is beneficial to avoid the decomposition and overflow of harmful substances in the glue to affect the user's health and affect the odor of the air around the mattress, ensuring that the mattress is healthy to use and the air in the use environment is fresh.
[0046] 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.
[0047] 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.
[0048] 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.
[0049] 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 mattress core 1 by means of nail guns. The handle strips 3 are fixed to the side wall of the mattress core 1, which facilitates the fixing or removal operation and helps improve the operating efficiency.
[0050] The surface layer (the comfort layer 2 is constrained by the surface layer and is fixed to the bed core 1) is fixed to the side wall of the bed core 11 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.
[0051] 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.
[0052] The upper layer 5, lower layer 6, and surrounding surface layer form a fully enclosed mattress, 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 3 is sewn and connected to the upper layer 5 or lower layer 6 through zipper closures, further ensuring that the mattress is glue-free.
[0053] In practical applications, the handle strip 3 can be arranged on the inner side of the surrounding surface layer to facilitate the fixation of the handle strip 3 and to avoid the influence of the handle strip 3 on the comfort of the mattress surface, thereby improving the comfort of the mattress.
[0054] 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.
[0055] 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.
