A mattress liner and mattress

Abstract

The application discloses a mattress liner and a mattress. The mattress liner comprises a plurality of support layers made of 3D cotton. The plurality of support layers comprises at least two reinforcing layers. Each reinforcing layer comprises a first surface and a second surface opposite to each other in a first direction. The second surface has a higher hardness than the first surface. All the support layers are stacked together, and the first surfaces of the at least two reinforcing layers are arranged to face each other. The second surface of the reinforcing layer can disperse stress to all parts of the support layer, thereby preventing the mattress liner from sagging. The second surface in the reinforcing layer located at the lower part can anchor the support layer at the bottom of the mattress liner. The reinforcing layer and other support layers jointly form a sandwich structure, which has good rigidity and can prevent the support layer from deviating. The defects that the 3D cotton mattress liner is prone to side bulging are solved. In addition, the reinforcing layer is surrounded by other support layers, so that the local stiffness caused by the reinforcing layer is avoided.

Description

Technical Field

[0001] This application relates to the field of furniture, and in particular to a mattress liner and mattress. Background Technology

[0002] 3D cotton mattresses, as a new type of mattress product, have gained widespread popularity in recent years due to the excellent resilience and breathability of their internal three-dimensional mesh structure. 3D cotton effectively distributes pressure and provides good support while facilitating air circulation, improving the comfort of the sleep environment. However, in actual use, pure 3D cotton mattresses have revealed certain structural defects. Because 3D cotton itself has a high elastic deformation capacity, when subjected to localized pressure from the human body, the pressure-bearing areas of the mattress surface are prone to significant sinking. This deformation leads to insufficient overall dimensional stability of the 3D cotton inner core during use, specifically manifesting as insufficient fullness around the sides of the 3D cotton inner core during mattress use.

[0003] To address this deficiency, existing technologies typically increase the length and width of the 3D cotton inner core to compensate for inward deformation under pressure, allowing the mattress to maintain a relatively full appearance even under load. However, this approach introduces new problems: with the inner core size increased while the outer shell size remains unchanged, the fit between the inner core and outer shell becomes uncoordinated, resulting in noticeable bulges on the sides of the mattress. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a mattress insert that can improve the problem of side bulging in existing 3D cotton mattresses.

[0005] According to one embodiment of this application, the mattress inner core includes multiple support layers, all of which are made of 3D cotton. At least two support layers are reinforcement layers. Each reinforcement layer includes a first surface and a second surface that are opposite each other in a first direction. The second surface is harder than the first surface. All support layers are stacked, and the second surfaces of at least two reinforcement layers are arranged facing each other.

[0006] According to one embodiment of this application, the remaining support layers are ordinary layers, and at least two reinforcing layers are stacked. Each reinforcing layer has a plurality of ordinary layers on its two opposite sides in the first direction. The hardness of the two opposite sides of the ordinary layers in the first direction is the same as the hardness of the first side.

[0007] According to one embodiment of this application, at least one support layer located in the middle is provided with a border around its periphery, and the thickness of the border is less than the thickness of the support layer.

[0008] According to one embodiment of this application, an adhesive layer is provided between two adjacent support layers, and the adhesive layer is provided at a first distance from the edge along the mid-surface of the surface where the two adjacent support layers are connected.

[0009] According to one embodiment of this application, each support layer is provided with a threading area, the threading area is at least a second distance from the edge of the support layer, and the threading area is provided with a plurality of lines running through all support layers along a first direction, the two ends of the lines being fixed to the two outermost support layers respectively.

[0010] According to one embodiment of this application, the threading area has 5 lines evenly arranged along the long side of the support layer and 4 lines evenly arranged along the wide side of the support layer.

[0011] The mattress according to another embodiment of this application includes the mattress liner described above.

[0012] A mattress according to another embodiment of this application includes: an inner cover layer for covering the mattress core; and an outer quilted layer for covering the inner cover layer.

[0013] According to another embodiment of the mattress of this application, the outer quilted layer includes a first 3D mesh layer, a first 3D cotton layer with a first thickness, a white cloth, a second 3D cotton layer with a first thickness, and a second 3D mesh layer; and / or, the two sides of the inner cover along the first direction are both third 3D cotton layers with a second thickness, and the other sides of the inner cover are all fourth 3D cotton layers with a third thickness.

[0014] The mattress liner according to the embodiments of this application has at least the following beneficial effects: the reinforcing layer has at least two layers, the second side of one reinforcing layer faces the side of the mattress liner where a person lies down, and the other reinforcing layer is located below the aforementioned reinforcing layer, the second side of which faces the side of the mattress liner where it is placed, and there is another supporting layer between the two reinforcing layers. With this design, on the one hand, the second surface of the upper reinforcing layer can distribute the stress exerted by the human body on the mattress core to various parts of the support layer, thereby maintaining the flatness of the mattress core surface. The second surface of the lower reinforcing layer can anchor the support layer at the bottom of the mattress core, preventing it from shifting and becoming loose during long-term use. On the other hand, there are other support layers between the reinforcing layers, and the reinforcing layers and other support layers together form a sandwich structure. When subjected to bending loads, the reinforcing layers bear tensile and compressive stresses, while the other support layers bear shear stresses, providing good rigidity and preventing the support layers from shifting. In summary, the mattress core of this application improves the defect of 3D cotton mattress cores being prone to bulging on the sides. In addition, the other support layers surround the reinforcing layers, avoiding the local stiffness caused by the reinforcing layers and ensuring a soft sleeping experience for the user.

[0015] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0023] The following is for reference. Figures 1 to 4 This application describes the mattress inner liner according to an embodiment of the present application.

[0024] It is worth noting that, with Figure 1 For example, the first direction of this application is the direction of the Z-axis. The positive direction of the Z-axis points to the top of the mattress inner core, and the negative direction of the Z-axis points to the bottom of the mattress inner core. The X-axis is the direction of the wide side of the mattress inner core, and the Y-axis is the direction of the long side of the mattress inner core.

[0025] Please see Figure 1 In one embodiment of this application, the mattress inner core includes multiple support layers 100, all of which are made of 3D cotton. At least two support layers 100 are reinforcing layers 110, and the remaining support layers 100 are ordinary layers 120. Each reinforcing layer 110 includes a first surface 102 and a second surface 101 that are opposite each other in a first direction. The hardness of the second surface 101 is greater than that of the first surface 102. The ordinary layer 120 includes two surfaces that are opposite each other in the first direction, and the hardness of the two surfaces is the same as that of the first surface 102. Each reinforcing layer 110 and each ordinary layer 120 are stacked. The reinforcing layers 110 and ordinary layers 120 are adjacent to each other, and the first surfaces 102 of at least two reinforcing layers 110 are arranged facing each other.

[0026] As an example, the mattress core includes eight support layers, of which there are two reinforcing layers 110 and six ordinary layers 120. The two reinforcing layers 110 are stacked, and each reinforcing layer 110 has two ordinary layers 120 on its opposite sides in the first direction.

[0027] In other words, with Figure 1 The mattress inner liner in this application is used as an embodiment of the present application. The upper part of the mattress inner liner is used for people to lie down and rest, and the lower part of the mattress inner liner is used for placement.

[0028] Here, 3D cotton refers to a fabric material with a three-dimensional structure, which includes a double-layer mesh and fiber filaments located in the middle of the double-layer mesh. The fiber filaments are arranged vertically and interwoven on the double-layer mesh through a warp knitting process, thereby forming the ordinary layer 120 referred to in this solution. The reinforcing layer 110 is based on the ordinary layer 120, and one of the mesh layers is subjected to a hardening treatment to give it differentiated support performance. Thus, of the two surfaces of the reinforcing layer 110, one surface is the first surface 102 and the other surface is the second surface 101. As an example, the mattress core includes eight support layers 100, two of which are reinforcement layers 110 and six are ordinary layers 120. The ordinary layers 120 and reinforcement layers 110 are stacked together. From the top to the bottom of the mattress core, the sequence is two ordinary layers 120, one reinforcement layer 110, two ordinary layers 120, one reinforcement layer 110, and two ordinary layers 120. The reinforcement layer 110 at the top has its second side 101 facing upwards and its first side 102 facing downwards, while the reinforcement layer 110 at the bottom has its first side 102 facing upwards and its second side 101 facing downwards. Furthermore, the vertically arranged fibers constituting the ordinary layers 120 and reinforcement layers 110 have different bending directions. During the stacking process of the six ordinary layers 120 and the two reinforcement layers 110, the bending directions of the 3D cotton fibers between adjacent layers are different, thereby giving the mattress core better support performance and inhibiting vertical collapse.

[0029] With this configuration, on the one hand, the second surface 101 of the upper reinforcing layer 110 can disperse the stress exerted by the human body on the mattress core to various parts of the support layer 100, thereby maintaining the flatness of the mattress core surface. On the other hand, the second surface 101 of the lower reinforcing layer 110 can anchor the support layer 100 at the bottom of the mattress core, preventing it from shifting and becoming loose during long-term use. On the other hand, there is a common layer 120 between the reinforcing layers 110. The reinforcing layers 110 and the common layer 120 together form a sandwich structure. When subjected to bending loads, the reinforcing layer 110 bears tensile and compressive stresses, while the common layer 120 bears shear stresses, providing good rigidity and preventing the support layer 100 from shifting.

[0030] In summary, the mattress liner of this application improves upon the defect of 3D cotton mattress liners being prone to bulging on the sides. Furthermore, the ordinary layer 120 surrounds the reinforcing layer 110, preventing localized stiffness caused by the reinforcing layer 110 and ensuring a soft sleeping experience for the user.

[0031] In some embodiments, such as Figure 2 As shown, at least one support layer 100 located in the middle is provided with a border 103 around its perimeter, and the thickness of the border 103 is less than the thickness of the support layer 100.

[0032] like Figure 1 and Figure 2As shown, the multi-layer support layer 100 located in the middle includes a first outer layer 130, an inner layer 140, and a second outer layer 150, arranged sequentially. The thickness of the inner layer 140 is less than that of the first outer layer 130 and the second outer layer 150. A frame 103 is provided around the periphery of the first outer layer 130 and the second outer layer 150. The frame 103 is made of high-carbon steel, and its thickness is less than that of the support layer 100. It is understood that the frame 103 can also be made of rigid plastic polymer materials, including ABS and PP. It is worth noting that the multi-layer support layer 100 located in the middle includes all support layers 100 except for the uppermost and lowermost support layers 100.

[0033] like Figure 1 and Figure 2 As shown, taking the multi-layer support layer 100 with six ordinary layers 120 and two reinforcing layers 110 as an example, the first outer layer 130 in this embodiment can be the fourth layer from top to bottom in the support layer 100, the inner layer 140 can be the fifth layer from top to bottom in the support layer 100, and the second outer layer 150 can be the sixth layer from top to bottom in the support layer 100. The inner layer 140 has a size of 176*196*0.6cm, and the other ordinary layers 120 and reinforcing layers 110 have a size of 178*198*2cm. The first outer layer 130 has a frame 103 fixed on its lower surface. The frame 103 is set along the outer contour of the lower surface of the first outer layer 130. The width of the frame 103 is within 2-4cm. At the four corners of the first outer layer 130, the frame 103 forms an arc with a radius of 1-2cm. This arc corner has a certain anti-collision function.

[0034] By adopting the above technical solution, the frame 103 of the first outer layer 130 and the frame 103 of the second outer layer 150 support the edge of the mattress core, solving the technical defect of insufficient support around the 3D cotton mattress core. In addition, an inner layer 140 is placed between the first outer layer 130 and the second outer layer 150. The inner layer 140 can ensure that the human body will not feel the frame 103 of the first outer layer 130 and the frame 103 of the second outer layer 150 when lying on the mattress core, thus improving the user experience.

[0035] It is understandable that the aforementioned combination process of the first outer layer 130, inner layer 140, and second outer layer 150 can be used in conjunction with the combination process of the reinforcing layer 110 and the ordinary layer 120. That is, the sixth layer from the top in the mattress core is the second outer layer 150, which can also be the reinforcing layer 110. The surface below the sixth layer is the second surface 101, and the surface above it is the first surface 102 with a frame 103. In this way, the advantages of both combination processes are combined. Of course, the combination process of the first outer layer 130, inner layer 140, and second outer layer 150 can also be applied alone to the 3D cotton mattress core to enhance the technical defect of insufficient support around the 3D cotton mattress core.

[0036] Furthermore, such as Figure 3 As shown, an adhesive layer is provided between two adjacent support layers 100, and the adhesive layer is located at a first distance from the edge along the surface where the two adjacent support layers are connected. Furthermore, the adhesive layer is specifically a solid adhesive. Using solid adhesive makes it less prone to slippage when bonding and fixing adjacent support layers 100. Compared to glue, solid adhesive is more stable in a predetermined position and less prone to flow. Specifically, from the first layer at the top to the eighth layer at the bottom, each layer of the mattress inner core is bonded together using a glue gun. The solid adhesive is located 5cm from the edge of the mattress inner core. Specifically, a glue gun is used to apply a ring of adhesive 5cm from the edge of the surface where the reinforcing layer 110 and the ordinary layer 120 connect with other ordinary layers 120 or the reinforcing layer 110, forming an adhesive area 170. This initially fixes each ordinary layer 120 and each reinforcing layer 110 without affecting the resilience and firmness of the 3D cotton material.

[0037] In some embodiments, such as Figure 4 As shown, the support layer 100 has a threading area 160, which is at least a second distance from the edge of the support layer 100. The threading area 160 has multiple lines running along a first direction through all the support layers 100, with both ends of the lines fixed to the two outermost support layers 100 respectively. That is, as... Figure 4 As shown, the support layer 100 is sewn with multiple threads that run vertically through the mattress core. These threads pass through an area on the support layer 100 at least 15cm from its edge, specifically in the middle of the support layer 100. The threads extend from the first layer to the eighth layer of the mattress core, leaving a trail like... Figure 4The threading hole 161 shown further secures the reinforcing layer 110 and the ordinary layer 120 with the thread passing through the mattress inner core. Furthermore, the threading area 160 has five threads evenly arranged along the long side of the support layer 100 and four threads evenly arranged along the wide side of the support layer 100. Both ends of each thread are fixed to the first and eighth support layers 100 by knotting. It is understood that the ends of the threads can also be fixed by methods other than knotting, such as heat fusion, where the ends of the threads are heat-fused to form a hardened adhesive particle. This adhesive particle can be embedded inside the support layer 100 to prevent the thread ends from slipping off.

[0038] Another embodiment of the mattress in this application includes the aforementioned mattress core; an inner sleeve layer for covering the mattress core; and an outer quilted layer for covering the inner sleeve layer. The outer quilted layer, along its first direction, is composed of 3D mesh fabric, 3D cotton with a first thickness, 30# white fabric, 3D cotton with a first thickness, and 3D mesh fabric. The inner sleeve has two sides with 3D cotton with a second thickness along its first direction, and the other sides with 3D cotton with a third thickness.

[0039] In other words, the mattress consists of a mattress core, an inner cover, and an outer quilted layer. The inner cover is also made of 3D cotton, with its top and bottom surfaces being 1.5cm thick third 3D cotton layers, and the other sides being 0.7cm thick fourth 3D cotton layers. The different surfaces of the inner cover are connected by stitching. To facilitate the removal of the mattress core inside the inner cover, a zipper is stitched on one side of the inner cover. Each side of the outer quilted layer has a structure consisting of a first 3D mesh layer, a 0.65cm thick first 3D cotton layer, a white cloth layer, a 0.65cm thick second 3D cotton layer, and a second 3D mesh layer. This structure ensures the breathability and resilience of the outer quilted layer. To facilitate the removal of the inner cover and mattress core, a zipper is also stitched on the side of the outer quilted layer.

[0040] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
