Description

Technical Field

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

[0002] In mattresses, the mattress mesh is a crucial support component, and its structural design plays a decisive role in the overall performance of the mattress. However, traditional mattress mesh structures have many shortcomings. For example, some traditional mattress meshes use a single type of individual pocket coils or a simple arrangement, which cannot accurately adapt to the pressure differences of different parts of the body. This design results in insufficient support for some parts of the body, while other parts may be over-supported. This not only affects sleep comfort but may also have adverse effects on spinal health. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a modular mattress that can provide different levels of support based on pressure differences at different positions of the user, thereby improving the user's mattress experience.

[0004] According to one embodiment of this application, a modular mattress includes an inner core layer, which includes a mattress mesh, an upper irregularly shaped pad, and a lower irregularly shaped pad. The mattress mesh has a first concave-convex structure along a first direction, conforming to the curve of the human body. The upper irregularly shaped pad is provided with a second concave-convex structure adapted to the mattress mesh, and when the upper irregularly shaped pad covers the mattress mesh, the mattress mesh and the upper irregularly shaped pad are interlocked. The lower irregularly shaped pad is provided with a third concave-convex structure adapted to the upper irregularly shaped pad, and when the upper irregularly shaped pad covers the lower irregularly shaped pad, the upper irregularly shaped pad and the lower irregularly shaped pad are interlocked.

[0005] According to one embodiment of this application, one side of the upper irregular pad is formed as a plane, and the other side is formed with a second concave-convex structure.

[0006] According to one embodiment of this application, one side of the lower irregular pad is formed as a plane, and the other side is provided with a third concave-convex structure adapted to the upper irregular pad.

[0007] According to one embodiment of this application, the inner liner includes an inner sleeve for combining the upper shaped pad and the lower shaped pad to form a double-layer pad.

[0008] According to one embodiment of this application, the modular mattress includes an upper layer and a lower layer, which together wrap an inner core layer. Both the upper and lower layers include a fabric layer, a fiber cotton layer, a sponge layer, and a non-woven fabric layer, which are arranged sequentially. The non-woven fabric layer is in contact with the inner core layer. A zipper is provided on the non-woven fabric layer of the upper layer, which is located along the edge of the non-woven fabric layer, for removing the upper and lower irregularly shaped pads located in the inner core layer.

[0009] According to one embodiment of this application, the basis weight of the upper layer of fiber cotton is greater than that of the lower layer of fiber cotton, and the thickness of the upper layer of sponge is greater than that of the lower layer of sponge.

[0010] According to one embodiment of this application, the bed net includes multiple sets of springs arranged side by side along a first direction of the bed net. Each set of springs includes multiple springs with the same wire diameter. The multiple springs are arranged along a second direction of the bed net. There is a difference in height between the multiple sets of springs. From any end of the first direction of the bed net to the middle of the first direction of the bed net, the height of the spring set first increases and then decreases.

[0011] According to one embodiment of this application, from any end of the bed net in a first direction to the middle of the bed net in a first direction, the number of spring coils first increases and then decreases.

[0012] According to one embodiment of this application, each spring is wrapped with a closed bag. After the spring is put into the closed bag, the closed bag compresses the spring. From any end of the bed net in the first direction to the middle of the bed net in the first direction, the height of the spring put into the closed bag first rises and then falls.

[0013] According to one embodiment of this application, the modular mattress includes a side guard disposed along the peripheral edge of the mattress mesh to support the edge of the mattress mesh.

[0014] The modular mattress according to the embodiments of this application has at least the following beneficial effects: along the first direction of the mattress net from any end of the long side to the middle of the long side, the height of the mattress net first increases and then decreases. The upper irregularly shaped pad is provided with a second concave-convex structure adapted to the mattress net. When the upper irregularly shaped pad covers the mattress net, the mattress net and the upper irregularly shaped pad interlock to provide the user with a soft sleeping experience. The lower irregularly shaped pad is provided with a third concave-convex structure adapted to the second concave-convex structure. The interlocking of the lower irregularly shaped pad and the upper irregularly shaped pad and their placement on the mattress net can slightly increase the firmness of the modular mattress, providing the user with different firmness options. The interlocking of the lower irregularly shaped pad and the upper irregularly shaped pad forms a double-layer mattress. Using the double-layer mattress alone can bring the user a softer sleeping experience than when the mattress net and the upper irregularly shaped pad are interlocked. The user can personalize the modular mattress according to their needs for mattress firmness. The adjustment process is convenient and does not require changing to a different mattress.

[0023] In mattresses, the mattress mesh is a crucial support component, and its structural design plays a decisive role in the overall performance of the mattress. However, traditional mattress mesh structures have many shortcomings. For example, some traditional mattress meshes use a single type of individual pocket coils or a simple arrangement, which cannot accurately adapt to the pressure differences of different parts of the body. This design results in insufficient support for some parts of the body, while other parts may be over-supported. This not only affects sleep comfort but may also have adverse effects on spinal health.

[0024] To address the aforementioned issues, this application provides a modular mattress that can provide different levels of support based on pressure differences at different user positions, thereby enhancing the user's mattress experience.

[0025] The following is for reference. Figures 1 to 8 A modular mattress according to an embodiment of this application is described.

[0026] It is worth noting that, please refer to Figure 1 The first direction of the bed net 100 in this application is Figure 1 The X-axis direction in the diagram, the first direction is the long side direction of the bed net 100, and the second direction is... Figure 1 The Y-axis direction is the second direction, which is the width direction of the bed net 100, and the height direction is... Figure 1 The Z-axis direction in the equation.

[0027] Reference Figure 1 and Figure 2 As shown, in one embodiment of this application, the combined mattress includes an inner core layer 1000, which includes a bed net 100. The bed net 100 includes multiple sets of spring groups 110 arranged side by side along the long side of the bed net 100. Each set of spring groups 110 includes multiple springs 111. The multiple springs 111 are arranged along the wide side of the bed net 100. The heights of the multiple spring groups 110 differ, and the height variation of the spring groups 110 forms a first concave-convex structure according to the curve of the human body.

[0028] In other words, such as Figure 2 As shown, the bed net 100 includes multiple sets of springs 110, each set of springs 110 including multiple springs 111. The multiple springs 111 in each set of springs 110 are arranged along the width of the bed net 100. Each spring 111 is wrapped with a closed bag 112, which is used to compress the spring 111 to a certain height. The closed bags 112 of each set of springs 110 are not exactly the same, therefore the heights of each set of springs 110 differ to some extent. Please refer to... Figure 2The spring groups 110 located at both ends of the long side of the mattress 100 and the spring group 110 located in the middle of the long side of the mattress 100 are lower in height than other spring groups 110. However, viewed as a whole, the height of each spring group 110 from any end of the long side of the mattress 100 to the middle of the long side first increases and then decreases. In this embodiment, the minimum height of the spring groups 110 of the mattress 100 is 66mm, and the maximum height is 120mm. The spring groups 110 with the minimum height are specifically located at both ends and the middle of the long side of the mattress 100, while the spring groups 110 with the maximum height are specifically located at one-quarter and three-quarters of the long side of the mattress 100. The height of the spring groups 110 between the minimum and maximum height at both ends of the long side of the mattress 100 shows a gradually increasing trend, with spring groups 110 measuring 66mm, 75mm, ... The height of the spring groups 110 gradually decreases from 84mm, 93mm, 102mm, 111mm, to 120mm. This transition occurs between the tallest spring group 110 and the shortest spring group 110 located in the middle of the mattress 100, with spring groups 110 exhibiting a gradual decrease in height. The spring groups 110 show a gradual transition from 120mm, 113mm, 107mm, 100mm, 93mm, 86mm, 79mm, 72mm, to 66mm, ultimately achieving a first concave-convex structure for each spring group 110 of the mattress 100, conforming to the curves of the human body. Within this first concave-convex structure, the lower spring groups 110 provide relatively firm support, while the higher spring groups 111 provide relatively soft support. This provides different levels of support based on pressure differences in different parts of the user's body, effectively relieving fatigue in various parts of the body and significantly improving the user's sleep comfort. It is worth noting that the spring assembly 110 with the maximum height in this application is not limited to being set at one-quarter and three-quarters of the long side of the bed net 100. This position can be adaptively adjusted according to factors such as the specific size of the bed net 100 and the target audience of the bed net 100.

[0029] In some embodiments, the springs 111 in the spring groups 110 located at both ends of the long side of the bed net 100 and the spring group 110 located in the middle of the long side of the bed net 100 have the smallest number of turns. From any end of the long side of the bed net 100 to the middle of the long side of the bed net 100, the number of turns of the springs 111 first increases and then decreases. In other words, in this embodiment, the minimum number of coils of each spring group 110 is 4.9 coils, and the maximum number of coils is 5.9 coils. The spring group 110 with the minimum number of coils is located at both ends of the long side of the bed net 100, and the spring group 110 with the maximum number of coils is located at one-quarter and three-quarters of the long side of the bed net 100. The number of coils of the spring group 110 between adjacent spring groups 110 with the minimum number of coils and spring groups 110 with the maximum number of coils shows a gradually increasing trend. The spring group 110 shows a gradual transition trend of 4.9 coils, 5.4 coils, and 5.9 coils, ultimately achieving a wave-like change in the number of coils of each spring group 110 of the bed net 100 corresponding to the human body curve. Springs 111 with fewer coils provide relatively firm support, while springs 111 with more coils provide relatively soft support. This perfectly matches the aforementioned height of the springs 111. In the wave-shaped arrangement of the spring groups 110, the lower spring groups 110 have relatively fewer coils, providing relatively firm support, while the higher spring groups 111 have relatively more coils, providing relatively soft support. This provides different levels of support based on the pressure differences in different parts of the user's body, effectively relieving fatigue in various parts of the body and improving the user's sleep comfort. It is worth noting that the spring group 110 with the maximum number of coils in this application is not limited to being located at one-quarter and three-quarters of the way along the long side of the bed net 100. This position can be adaptively adjusted according to the specific size of the bed net 100, the target users, and other factors.

[0030] In some embodiments, the springs 111 located at both ends of the long side of the bed net 100 and the spring 111 located in the middle of the long side of the bed net 100 are at their lowest height before being wrapped in the closed bag 112. From any end of the long side of the bed net 100 to the middle of the long side of the bed net 100, the height of the spring assembly 110 first increases and then decreases.

[0031] In other words, in this embodiment, the minimum height of spring 111 in each spring group 110 before being inserted into the closed bag 112 is 160mm, and the maximum height before being inserted into the closed bag 112 is 190mm. The spring group 110 with the minimum height before being inserted into the closed bag 112 is specifically located at both ends of the long side of the bed net 100, and the spring group 110 with the maximum height before being inserted into the closed bag 112 is specifically located at one-quarter and three-quarters of the long side of the bed net 100. The height of the spring group 110 between adjacent minimum height and maximum height spring groups 110 shows a gradually increasing trend, with the spring group 110 showing a gradual transition trend of 160mm, 175mm, and 190mm. Ultimately, the height of spring 111 in each spring group 110 of the bed net 100 before being inserted into the closed bag 112 is also formed to change in a first concave-convex structure along the long side of the bed net 100 according to the curve of the human body. This change trend also happens to match the height of the spring group 110 after being inserted into the closed bag 112. For example, arranging the springs 111 from one end of the long side of the bed net 100 to the middle of the long side, the compression of the springs 111 before and after compression is as follows: First, three sets of springs 111 with a height of 160mm are respectively placed into the sealed bag 112. These three sets of springs 111 have 4.9 coils, and their heights are compressed to 66mm, 75mm, and 84mm respectively; next, a set of springs 111 with a height of 175mm is placed into the sealed bag 112. This set of springs 111 has 5.4 coils, and its height is compressed to 93mm; then, five sets of springs 111 with a height of 190mm are placed into the sealed bag. 112. The three sets of springs 111 have 5.9 coils each, and their heights are compressed to 102mm, 111mm, 120mm, 113mm, and 107mm respectively. Next, two sets of springs 111 with a height of 175mm are placed in the sealed bag 112. These two sets of springs 111 have 5.4 coils each, and their heights are compressed to 100mm and 93mm respectively. Finally, four sets of springs 111 with a height of 160mm are placed in the sealed bag 112. These four sets of springs 111 have 4.9 coils each, and their heights are compressed to 86mm, 79mm, 72mm, and 66mm respectively. The arrangement of the springs 111 from the other end of the long side of the bed net 100 along the long side to the middle of the long side is consistent with the above, and the two are arranged symmetrically.As can be seen, the spring assembly 110, with a height of 190mm and a height of 120mm after being inserted into the closed bag 112, provides relatively soft support, and this point is located at one-quarter of the long side of the mattress 100. The spring assembly 110, with a height of 160mm and a height of 66mm after being inserted into the closed bag 112, provides relatively firm support. This also corresponds to the aforementioned trends in the height variation of the spring assembly 110 and the number of coils of the spring 111. It can provide different support according to the pressure differences of different parts of the user's body, further improving the support effect of the mattress 100 in various parts, effectively relieving fatigue in various parts of the user's body, and improving the user's sleep comfort. It is worth noting that the spring 111 with the maximum height before being inserted into the closed bag 112 is not limited to being set at one-quarter and three-quarters of the long side of the mattress 100. This position can be adaptively adjusted according to the specific size of the mattress 100, the target users of the mattress 100, and other factors.

[0032] In some embodiments, such as Figure 1 As shown, the modular mattress includes a side rail 120, which is positioned along the periphery of the mattress 100 to support its edges. Understandably, when using a mattress 100 without edge reinforcement, the user applies force to the edges, causing significant pressure on the springs 111. However, due to insufficient support, the springs 111 are easily overcompressed, leading to edge collapse and potentially causing the user to slip and injure themselves. Therefore, the side rail 120 of this application is made of high-density, high-firm foam. Encircling the periphery of the mattress 100 enhances its stability and prevents collapse due to excessive compression of the springs 111 at the edges.

[0033] In some embodiments of this application, such as Figure 3 and Figure 5 As shown, the modular mattress includes an inner core layer 1000, which further includes an upper irregularly shaped pad 200 and a lower irregularly shaped pad 300. The upper irregularly shaped pad 200 is provided with a second concave-convex structure 210 adapted to the bed net. When the upper irregularly shaped pad 200 is covered by the bed net 100, multiple sets of springs 110 extend into the second concave-convex structure 210. One side of the upper irregularly shaped pad 200 is formed as a flat surface, and the other side is formed with the second concave-convex structure 210. One side of the lower irregularly shaped pad 300 is formed as a flat surface, and the other side is provided with a third concave-convex structure 310 adapted to the upper irregularly shaped pad 200. When the upper irregularly shaped pad 200 is covered by the lower irregularly shaped pad 300, the upper irregularly shaped pad 200 and the lower irregularly shaped pad 300 are interlocked.

[0034] In other words, the modular mattress includes an upper irregularly shaped pad 200 that fits the mattress 100. It can be understood that the upper irregularly shaped pad 200 has a second concave-convex structure 210. The upper irregularly shaped pad 200 covers the multiple spring groups 110 of the mattress 100. The higher spring groups 110 on the mattress 100 can extend into the concave part of the second concave-convex structure 210. After being covered, the upper irregularly shaped pad 200 provides the user with a soft sleeping experience. To increase the available firmness of the mattress, the modular mattress also includes a lower shaped pad 300. The lower shaped pad 300 has a third concave-convex structure 310 with the same trend as the spring assembly 110 of the mattress 100. Therefore, the upper shaped pad 200 can also be used in conjunction with the lower shaped pad 300. After the upper shaped pad 200 and the lower shaped pad 300 are combined and placed on the mattress 100, since the spring assemblies 110 on the mattress 100 no longer extend into the concave part of the second concave-convex structure 210 of the upper shaped pad 200, compared with the combination of the upper shaped pad 200 and the mattress 100, the combined action of the mattress 100, the upper shaped pad 200 and the lower shaped pad 300 will slightly increase the firmness of the modular mattress.

[0035] In some embodiments, such as Figure 5 As shown, the modular mattress includes an inner cover 500, which is used to combine the upper irregular-shaped pad 200 and the lower irregular-shaped pad 300 to form a double-layer mattress. That is, the user aligns the second concave-convex structure 210 of the upper irregular-shaped pad 200 with the third concave-convex structure 310 of the lower irregular-shaped pad 300, and then wraps the combined upper irregular-shaped pad 200 and lower irregular-shaped pad 300 together with the inner cover 500 to form a double-layer mattress. The user can use the double-layer mattress alone to obtain a softer sleep experience than when the upper irregular-shaped pad 200 is combined with the mattress net 100.

[0036] In some embodiments, such as Figure 4 , Figure 6 and Figure 8 As shown, the modular mattress also includes an upper layer 2000 and a lower layer 3000. The modular mattress is arranged along... Figure 4 Along the Z-axis, the layers are arranged in sequence: lower layer 3000, inner liner layer 1000, and upper layer 2000. The upper layer 2000 and lower layer 3000 together enclose the inner liner layer 1000. The inner liner layer 1000 includes a bed net 100, an upper shaped mattress 200, a lower shaped mattress 300, an inner sleeve 500, and a support layer 400. The inner liner layer 1000 extends along... Figure 4 Along the Z-axis, the layers are, in order: support layer 400, bed net 100, lower irregular pad 300, and upper irregular pad 200. Inner sleeve 500 is used to wrap the upper irregular pad 200 and the lower irregular pad 300. The support layer 400 is made of a 20mm thick layer of palm fiber, which can support the bed net 100 above it and prevent the bed net 100 from sinking.

[0037] In addition, such as Figure 7As shown, a zipper 910 is provided on the non-woven fabric layer 900 of the upper layer 2000. The zipper 910 is provided along the edge of the non-woven fabric layer 900 and is used to remove the upper irregularly shaped pad 200 and the lower irregularly shaped pad 300, so that the user can switch between the mattress firmness according to the desired firmness. If the user places the upper shaped mattress 200 and the lower shaped mattress 300 into the inner core layer 1000, the combined effect of the mattress mesh 100, the upper shaped mattress 200, and the lower shaped mattress 300 provides a firmer sleep experience. If the user removes the lower shaped mattress 300 from the inner core layer 1000, the combined effect of the upper shaped mattress 200 and the mattress mesh 100 provides a softer sleep experience compared to the combined effect of the three. If the user removes both the upper shaped mattress 200 and the lower shaped mattress 300 from the inner core layer 1000 and then wraps them with the inner sleeve 500 to form a double-layer mattress, using the double-layer mattress alone provides a softer sleep experience than the two firmness levels mentioned above. Understandably, users can switch between different mattress combinations according to their individual sleep requirements, and by combining the spring assembly 110 on the mattress mesh 100 to provide different levels of support in different areas, the user's sleep comfort can be improved.

[0038] In some embodiments, both the upper layer 2000 and the lower layer 3000 include a fabric layer 600, a fiber cotton layer 700, a sponge layer 800, and a nonwoven fabric layer 900, arranged sequentially, with the nonwoven fabric layer 900 in contact with the inner lining layer 1000; the basis weight of the fiber cotton layer 700 in the upper layer 2000 is greater than that of the fiber cotton layer 700 in the lower layer 3000, and the thickness of the sponge layer 800 in the upper layer 2000 is greater than that in the lower layer 3000.

[0039] In other words, in this embodiment, the upper layer 2000 and the lower layer 3000 have similar structures, both including a fabric layer 600, a fiber cotton layer 700, a sponge layer 800, and a non-woven fabric layer 900. The fabric layer 600, the fiber cotton layer 700, the sponge layer 800, and the non-woven fabric layer 900 are combined together by a quilting process. The fiber cotton layer 700 in both the upper layer 2000 and the lower layer 3000 is made of fiber cotton. The weight of the fiber cotton in the upper layer 2000 is 300g, and the weight of the fiber cotton in the lower layer 3000 is between 180g and 200g. It can be understood that the fiber cotton layer 700 of the upper layer 2000 is thicker, which can increase the user's sleeping comfort when lying on the upper layer 2000. The upper layer 2000 has two foam layers 800, each 15mm thick, both made of soft foam to provide users with sleep comfort; the lower layer 3000 has a single foam layer 800, 15mm thick, supported by firm foam, together with the support layer 400 to form a double-layer support structure for the mattress to prevent mattress sagging and improve the overall structural strength.

[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.
