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. Summary of the Invention

[0003] The purpose of the present utility model 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 through the surface layer, and the surface layer is fixed to the bed core through the handle cloth strip and the connecting piece, so that the fixation of the comfort layer and the surface layer is glue-free. In addition, the fixation of the surface layer and the surrounding edge is a stitching connection, which is also glue-free. If the comfort layer is a multi-layer structure, it is fixed by a fixing structure at the periphery of the comfort layer, which is also glue-free, so that the entire mattress is a glue-free mattress, which is beneficial to improving the health of the mattress and keeping the surrounding air fresh, and is also beneficial to the disassembly, recycling and reuse of the mattress.

[0004] The above technical objectives of the present invention are primarily achieved through the following technical solution: a glue-free mattress comprising a mattress core, a comfort layer covering the surface of the mattress core, and a surface layer covering the mattress core and the comfort layer, characterized in that a handle strip is provided on the inner side of the surface layer, the handle strip being provided corresponding to the side of the mattress core, and the handle strip being fixed to the side of the mattress core via a connector, thereby forming a fixed connection between the surface layer and the mattress core. In this technical solution, the comfort layer is fixed to the mattress core via the surface layer, which is in turn fixed to the mattress core via the handle strip and the connector, thereby achieving a glue-free connection between the comfort layer and the surface layer, at least in the outermost structure of the mattress. This helps prevent the decomposition and spillage of harmful substances in the glue from affecting the user's health and the odor of the air surrounding the mattress, thereby ensuring healthy use of the mattress and fresh air in the environment. Furthermore, the glue-free connection prevents the generation of unusual noises, thus ensuring a quiet environment and improving the quality of rest and sleep for the user. In addition, the use of glue-free connection makes disassembly easy, reducing or even avoiding destructive disassembly of the surface layer, comfort layer, bed core and other structures, which is conducive to the disassembly, recycling and reuse of the mattress, and is conducive to energy conservation and emission reduction.

[0005] In addition, in this technical solution, all parts of the mattress, such as the comfort layer and the surface layer, are made of raw materials without glue.

[0006] As a further improvement and supplement to the above-mentioned technical solution, the present invention employs the following technical measures: the handle strips are at least two strips spaced apart, one above the other. The handle strips are secured to the side walls of the mattress core, facilitating both mounting and removal operations and improving operational efficiency. The two strips, spaced apart, enhance securement and prevent displacement of the mattress's top and comfort layers during transport, ensuring they remain stably positioned on the mattress.

[0007] Preferably, the handle strip is fixed to the side of the bed core by means of a nail gun.

The upper layer, lower layer, and peripheral layer form a fully enclosed structure, which improves the overall quality and visual effect of the mattress. The various components are connected by glue-free sewing, sewing zippers, and zipper connections, further ensuring that the mattress is glue-free.

[0009] Preferably, the comfort layer is disposed on one side of the bed core or on two opposing sides thereof. The material of the comfort layer is at least one of latex, sponge, and 3D mesh, and the comfort layer is secured to the bed core via a surface layer. The comfort layer may be a single layer or multiple layers. In the case of a multiple layer structure, the materials of the various comfort layers may be the same or different, depending on actual design requirements or usage needs.

[0010] Preferably, the comfort layer is a single-layer structure or a multi-layer structure of at least two layers. In the case of a multi-layer structure, a fixing structure is provided around the periphery of the comfort layer, and the fixing structure penetrates back and forth through the comfort layer to connect the multi-layer comfort layers together. The multi-layer comfort layer is secured using a glue-free, back-and-forth penetrating fixing structure, further ensuring that the mattress is glue-free.

[0011] Preferably, the fixing structure is a suture structure.

[0012] Preferably, the comfort layer comprises an outer latex layer and an inner sponge layer, each of which is provided with a plurality of spaced-apart slit sections. To enhance the comfort of the comfort layer, a structure of at least two layers made of different materials is employed. To further enhance comfort, the slit sections facilitate the formation of zones in the comfort layer, providing different levels of support for different body parts when the user lies on the mattress.

[0013] Preferably, three spaced-apart cutting seam sections are provided on the latex layer and the sponge layer, so that the latex layer and the sponge layer each form five spaced-apart support drives with differentiated hardness; the cutting seam sections on the latex layer and the corresponding cutting seam sections on the sponge layer are staggered, and local sections overlap.

[0021] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0022] Example: Figures 1-4 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.

[0023] This technical solution differs from the prior art in that a handle strip 3 is provided on the inner side of the surface layer, the handle strip 3 being arranged corresponding to the side of the bed core 1. The handle strip 3 is fixed to the side of the bed core 1 via a connector 4, thereby forming a fixed connection between the surface layer and the bed core 1. Furthermore, in this technical solution, all components of the mattress, including the comfort layer and the surface layer, are made of raw materials without glue.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] In actual use, to improve the reliability of the fixing and prevent the surface layer and comfort layer 2 from shifting during transportation, the handle strips 3 are at least two strips spaced apart. The surface layer (the comfort layer 2 is constrained and fixed to the bed core 1 by the surface layer) is fixed to the side wall of the bed core 1 by the handle strips 3, which facilitates the fixing and removal operations and improves the operating efficiency.

[0029] 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.

[0030] 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 zippers. The handle fabric is sewn and connected to the top layer 5 or bottom layer 6 through zippers, further ensuring that the mattress is glue-free.

[0031] 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.

[0032] Next, we will further explain other structures on the mattress to make the technical solution more complete:

[0033] 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. The material of the comfort layer 2 is at least one of latex, sponge, and 3D mesh. The comfort layer 2 is fixed to the bed core 1 through a surface layer.

[0034] In practical applications, the comfort layer 2 is a single-layer structure or a multi-layer structure of at least two layers. When it is a multi-layer structure, the materials of the comfort layers 2 can be the same or different, depending on the actual design requirements or usage requirements.

[0035] In practical applications, when the comfort layer 2 is a multi-layer structure, a fixing structure 8 is provided around the periphery of the comfort layer 2. The fixing structure 8 penetrates the comfort layer 2 back and forth to connect the multi-layer comfort layers 2 together. The multi-layer comfort layer 2 is fixed by the fixing structure 8 that penetrates back and forth without glue, further ensuring that the mattress is free of glue.

[0036] In order to further improve the fixing reliability of the multi-layered comfort layer 2 , a fixing structure 8 may be provided in the middle area of ​​the comfort layer 2 .

[0037] In practical applications, the fixing structure 8 is a suture structure. The suture structure can be completed efficiently and with high quality on the comfort layer 2 by a suture machine, and the cotton thread is guided by steel nails to sew.

[0038] In practical applications, in order to improve the comfort of the comfort layer 2, a comfort layer 2 with at least two layers of different materials is used. Preferably, the comfort layer 2 includes an outer latex layer and an inner sponge layer.

[0039] In actual use, to further enhance comfort, the latex layer and the sponge layer are each provided with a plurality of spaced-apart cutout sections 9. The provision of the cutout sections facilitates the formation of zones in the comfort layer 2, providing different levels of comfort support for different body parts when the user lies on the mattress.

[0040] In this embodiment, three cutting seam sections 9 are respectively provided on the latex layer and the sponge layer, so that both the latex layer and the sponge layer form a five-partition structure.

[0041] In actual use, three spaced-apart cutout sections 9 are provided on each of the latex layer and the sponge layer, forming five spaced-apart support structures with varying degrees of hardness. Preferably, the cutout sections 9 on the latex layer and the corresponding cutout sections 9 on the sponge layer are staggered, with some sections overlapping, to provide a more layered support effect and further improve the user's rest and sleep quality when using the mattress.

[0042] In practical applications, the bed core 1 is a bed core 1 of several independent pocket springs or a Bonnier spring bed core 1 , and adjacent independent pocket springs are connected by ultrasonic welding.

[0043] Specifically, the independent springs are housed in independent cloth bags, and the bed core 1 formed by ultrasonically welding adjacent cloth bags and the Bonnier spring bed core 1 do not contain glue, further ensuring that the mattress does not contain glue, ensuring that the mattress is healthy to use and convenient for recycling.
