Description

Technical Field

[0001] This utility model relates to the field of home furnishing technology, specifically to a lightweight mattress structure and an air bed including the mattress structure. Background Technology

[0002] With the popularization of the concept of deep sleep, mattresses made primarily of elastic materials such as foam and silicone have become a core category for upgrading outdoor camping. Their excellent elasticity and conformability bring consumers a comfortable experience, but the high density and large volume also bring problems such as high weight, large size, and difficulty in storage.

[0003] Currently, the industry standard for foam mattresses is "post-foam cutting": at the front-end processing station, a vertical or horizontal band saw / wire saw is used to cut the entire foam into equal-distance sections longitudinally (along the length direction) or laterally (along the width direction), achieving weight reduction and compression by "hollowing out" parts of the material. However, this process only treats "weight" as the sole optimization objective, lacking a systematic design for the resulting geometry, waste material flow, and reuse paths. Its structure often suffers from uneven stress distribution and low material utilization.

[0004] Therefore, there is an urgent need for a mattress structure that can significantly reduce weight, be easy to store, and have high material utilization while ensuring good support and comfort. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a lightweight mattress structure and air bed. Through a unique complementary design of the support body and the groove body, it achieves a balance of lightweight, high support and comfort, and optimizes material utilization and storage volume.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] On the one hand, this utility model provides a lightweight mattress structure, including a mattress body, the mattress body including a support body and a middle body, the support body including a plurality of top supports and a plurality of bottom supports, the middle body being located between the top supports and the bottom supports, a groove being formed between adjacent support bodies, the groove including a top groove formed between adjacent top supports and a bottom groove formed between adjacent bottom supports, and a bottom support being disposed directly below each top support.

[0008] Preferably, the supports are distributed in any of the following ways:

[0009] The support body is arranged as one in the width direction of the mattress body, and the support body is arranged as several evenly distributed in the length direction of the mattress body;

[0010] The support body is arranged as one in the length direction of the mattress body, and the support body is arranged as several evenly distributed in the width direction of the mattress body;

[0011] The support body is arranged in a plurality of evenly distributed components along the length of the mattress body and in a plurality of evenly distributed components along the width of the mattress body.

[0012] Preferably, the cross-section of the support includes a support contact edge, a support transition edge, and a support connecting edge. The support contact edge is an outer edge that is straight as a whole. The support connecting edge is the boundary edge between the support and the intermediate body. The support transition edge is the edge line where the support contact edge transitions to the support connecting edge. The length of the support contact edge is greater than or equal to the length of the support connecting edge.

[0013] Preferably, the cross-section of the tank includes a tank opening edge, a tank transition edge, and a tank connecting edge. The tank opening edge is an externally located, straight edge. The tank connecting edge is the boundary line between the tank and the intermediate body. The tank transition edge is the edge line where the tank opening edge transitions to the tank connecting edge. The length of the tank connecting edge is greater than or equal to the length of the tank opening edge.

[0014] Preferably, the length of the contact edge of the support is 2 to 4 times the length of the groove edge of the groove, and the cross-sectional shape profile of the support is complementary to the cross-sectional shape profile of the groove.

[0015] Preferably, the cross-section of the support is trapezoidal, rectangular, or T-shaped.

[0016] Preferably, the support includes an externally disposed, planar support contact surface, and the groove includes an externally disposed groove, wherein the area of ​​the support contact surface is greater than or equal to the area of ​​the groove.

[0017] Preferably, the mattress body is cut from a porous elastic material, and the porous elastic material can be cut into several identical, stacked mattress bodies, with adjacent mattress bodies;

[0018] Between adjacent mattress bodies, the bottom support of the upper mattress body is embedded in the top groove of the lower mattress body, and the top support of the lower mattress body is embedded in the bottom groove of the upper mattress body.

[0019] On the other hand, this utility model provides an air bed, including a cover cloth that wraps around the lightweight mattress structure described in any of the above claims, and the cover cloth is provided with an inflation valve.

[0020] Preferably, the cover fabric includes a cover fabric, sidewalls, and a bottom fabric, wherein the cover fabric and sidewalls are made of skin-friendly materials, and the bottom fabric is made of TPU or PVC materials.

[0021] The beneficial effects of this utility model are:

[0022] This application utilizes top and bottom supports with a groove between them to provide solid support at key stress points while eliminating a significant amount of non-load-bearing material, thus significantly reducing the overall weight of the mattress while maintaining support strength. The mattress structure is particularly suitable for cutting from a single piece of porous elastic material, resulting in almost no material waste and effectively reducing production costs. When stacked, the unique complementary interlocking design allows multiple mattresses to interlock tightly, resulting in a volume far smaller than that of traditional solid mattresses, greatly facilitating storage, transportation, and home organization. This application can be used alone as a regular mattress or combined with an air cover as a core filling to form a comfortable and lightweight air bed, expanding its application scenarios.

[0040] Example 1

[0041] like Figure 1-10 As shown, this embodiment provides a lightweight mattress structure, including a mattress body 1. The mattress body 1 includes a support body 2 and an intermediate body 3. The support body 2 includes a plurality of top supports 21 and a plurality of bottom supports 22. The intermediate body 3 is located between the top supports 21 and the bottom supports 22. A groove 4 is formed between adjacent support bodies 2. The groove 4 includes a top groove 41 formed between adjacent top supports 21 and a bottom groove 42 formed between adjacent bottom supports 22. A bottom support 22 is arranged directly below each top support 21.

[0042] The top support 21 is located on the upper part of the mattress body 1 and is the support part that directly contacts the human body or the upper structure. The bottom support 22 is located on the lower part of the mattress body 1 and is the support part that contacts the ground or the lower structure. The two are connected as a whole by the intermediate body 3. The grooves 4 are naturally formed between the adjacent support bodies 2. The existence of the grooves 4 reduces the amount of material used, achieves a lightweight effect, and may also enhance breathability.

[0043] The top support 21 and bottom support 22 are aligned vertically to form a stable support frame. Therefore, the pressure applied by the human body to a certain top support 21 can be directly transferred to the support surface (such as the bed board or the ground) through the bottom support 22 directly below, avoiding the disorderly diffusion of stress in the intermediate body 3 and preventing excessive deformation and collapse of the mattress.

[0044] Regarding the distribution of support 2, support 2 can be distributed in any of the following ways:

[0045] Method 1, such as Figure 2 As shown, there is one support body 2 in the width direction of the mattress body 1, and several support bodies 2 are evenly distributed in the length direction of the mattress body 1. This method means that the support bodies 2 present a single row and multiple columns layout, similar to a long strip support structure being divided into several segments along the length direction, with grooves 4 formed between each segment, presenting an overall multi-segment support arranged in a straight line.

[0046] Method 2, such as Figure 3As shown, there is one support body 2 along the length of the mattress body 1, and several support bodies 2 are evenly distributed along the width of the mattress body 1. This arrangement means that the support bodies 2 present a multi-row, single-column layout, similar to a long strip of support structure being divided into several strips along the width direction, with grooves 4 formed between each strip, presenting multiple parallel supports as a whole.

[0047] Method 3, such as Figure 4-5 As shown, the support bodies 2 are evenly distributed along the length of the mattress body 1 and also evenly distributed along the width of the mattress body 1. This arrangement means the support bodies 2 present a multi-row, multi-column layout. Looking at both the length and width of the mattress, the support bodies 2 are evenly divided into several independent parts. These independent support bodies 2 are interwoven to form a grid-like arrangement, and grooves 4 are formed between adjacent support bodies 2 (regardless of length or width).

[0048] Preferred, such as Figure 7-8 As shown, the cross-section of the support 2 includes a support contact edge 23, a support transition edge 24, and a support connecting edge 25. The support contact edge 23 is an outer edge that is straight as a whole. The support connecting edge 25 is the boundary edge between the support 2 and the intermediate body 3. The support transition edge 24 is the edge line where the support contact edge 23 transitions to the support connecting edge 25. The length of the support contact edge 23 is greater than or equal to the length of the support connecting edge 25.

[0049] The cross-section of support 2 (i.e., the outline formed after cutting along a direction perpendicular to the mattress surface, such as...) Figure 1 The AA direction section consists of three key edges:

[0050] 1. Support contact edge 23: Located on the outermost side of the support 2, it is the edge line that directly contacts the outside (such as the contact edge of the top support 21 contacting the human body or the upper structure, and the contact edge of the bottom support 22 contacting the ground or the lower structure). The support contact edge 23 is straight as a whole to ensure the stability of the contact and the uniformity of the force.

[0051] 2. Support Body Connecting Edge 25: This is the boundary line between the support body 2 and the intermediate body 3, defining their structural boundaries. It's important to note that the supporting body connecting edge 25 does not mean that the support body 2 and the intermediate body 3 are two physically independent components joined together by adhesive. In this embodiment, the support body 2 and the intermediate body 3 are two integrally formed parts with different names; they are not physically independent. In other embodiments, the support body 2 and the intermediate body 3 can be formed independently and then spliced ​​together.

[0052] 3. Transition edge 24 of the support body: The transition part connecting the contact edge 23 of the support body and the connecting edge 25 of the support body. Its function is to smoothly connect the edge lines of the inner and outer sides, so that the force can be smoothly transmitted from the contact edge to the connecting edge, and then to the intermediate body 3, avoiding stress concentration.

[0053] The length of the contact edge 23 of the support body is greater than or equal to the length of the connecting edge 25 of the support body to ensure the contact area. When the contact edge is longer, the contact area between the support body 2 and the outside is larger, which can distribute the pressure and improve the stability and comfort of the support. The shorter connecting edge length can reduce the connection area between the support body 2 and the intermediate body 3, reduce the amount of material used while ensuring strength, and conform to the lightweight design concept.

[0054] Preferred, such as Figure 7-8 As shown, the cross-section of the tank 4 includes a tank opening edge 43, a tank transition edge 44, and a tank connecting edge 45. The tank opening edge 43 is an outer edge that is straight as a whole. The tank connecting edge 45 is the boundary edge between the tank 4 and the intermediate body 3. The tank transition edge 44 is the edge line where the tank opening edge 43 transitions to the tank connecting edge 45. The length of the tank connecting edge 45 is greater than or equal to the length of the tank opening edge 43.

[0055] The cross-section of the trough 4 (is in the same cutting direction as the cross-section of the support 2, such as...) Figure 1 The AA direction section consists of three key edges:

[0056] 1. Slot edge 43: Located at the outermost opening of the slot 4, it is the virtual edge where the slot 4 contacts the external space. The entire virtual edge is straight, ensuring that the slot 46 has a regular shape, which is beneficial to the breathability and structural consistency of the mattress.

[0057] 2. Tank body connecting edge 45: This is the dividing line connecting the tank body 4 and the intermediate body 3, defining the structural boundary between the tank body 4 and the intermediate body 3. Since the tank body 4 itself is a hollow non-solid, the tank body connecting edge 45 is the virtual edge line of the upper surface of the intermediate body 3.

[0058] 3. Transition edge 44 of the tank body: This is the transition part connecting the groove opening edge 43 and the connecting edge 45 of the tank body. Its function is to smoothly connect the groove opening 46 with the interior, avoid stress concentration caused by sharp corners at the edge of the tank body 4, and ensure the continuity of the intermediate body 3 structure. Since the tank body 4 itself is a hollow non-solid, the connecting edge 45 of the tank body is located in the same position as the transition edge 24 of the support body.

[0059] The shorter length of the groove edge 43 allows for better control of the opening size of the groove 4, reducing material usage while avoiding excessive weakening of the overall structural strength of the mattress.

[0060] Preferred, such as Figure 9-10As shown, the length of the support contact edge 23 is 2 to 4 times the length of the groove opening edge 43. The cross-sectional shape of the support 2 is complementary to that of the groove 4. The length of the support contact edge 23 (which directly bears the support function) is greater than that of the groove opening 46, ensuring sufficient support area and avoiding insufficient support due to the groove 4 being too large. The 2-4 times ratio reduces material usage through the groove 4 and ensures structural strength through the relative size of the support 2, preventing the mattress from easily deforming due to the groove 4 being too wide.

[0061] The cross-sectional shape of the support 2 is complementary to that of the groove 4, meaning the outer contour of the support 2's cross-section perfectly matches the inner contour of the groove 4's cross-section, similar to the interlocking texture of a jigsaw puzzle. This design allows the support 2 and groove 4 to form a continuous and regular whole in cross-section, reducing structural redundancy and enhancing the mechanical stability of the mattress body 1. Furthermore, when multiple mattress bodies 1 need to be stacked, such as for thickening mattresses or for transportation purposes, the bottom support 22 of the upper mattress can be precisely embedded into the top groove 41 of the lower mattress (or vice versa), achieving a stable connection through complementary shapes. In addition, the complementary shapes facilitate mass production using molds or cutting processes, reducing material waste and improving production efficiency.

[0062] Preferred, such as Figure 7-8 As shown, the cross-section of the support 2 is trapezoidal, rectangular, or T-shaped.

[0063] When the cross-section of the support 2 is trapezoidal, the two parallel sides of the trapezoid are as follows: the longer side is the support contact side 23, the shorter side is the support connecting side 25, and the two inclined sides are the support transition side 24.

[0064] When the cross-section of the support 2 is rectangular, the contact side 23 of the support and the connecting side 25 of the support are parallel and of equal length, and the transition side is perpendicular to both. This shape and structure is simple, provides strong support stability, and is suitable for scenarios with high structural strength requirements.

[0065] When the cross section of the support 2 is T-shaped, for the top support 21, the top of the horizontal part of the T is the support contact edge 23, the bottom of the vertical part of the T is the support connecting edge 25, and the rest is the support transition edge 24.

[0066] It should be noted that the above descriptions of trapezoids, rectangles, or T-shapes do not require their dimensions to meet the precise mathematical definitions of each shape; they only need to roughly conform to or approximate the shape.

[0067] Example 2

[0068] In this embodiment, as Figure 6 As shown, the support 2 includes a support contact surface 26 that is disposed on the outside and is generally planar, and the groove 4 includes a groove 46 disposed on the outside. The area of ​​the support contact surface 26 is greater than or equal to the area of ​​the groove 46.

[0069] The support contact surface 26 refers to the flat part of the support 2 exposed to the outside of the mattress, such as the upper surface of the top support 21 and the lower surface of the bottom support 22. It is the part that directly contacts the human body, the ground or other structures. Its whole is flat to ensure the stability of the contact and the uniformity of the force.

[0070] The slot 46 of the tank body 4 refers to the part of the tank body 4 that communicates with the external space, such as the upper opening of the top slot 41 and the lower opening of the bottom slot 42. It is a key structure for the tank body 4 to achieve lightweight and breathable functions.

[0071] The area of ​​the support contact surface 26 is greater than or equal to the area of ​​the groove 46, ensuring that the support area accounts for a larger proportion of the mattress surface and avoiding problems such as insufficient support points and concentrated force due to an excessively large groove 46. At the same time, the larger contact surface can distribute pressure and reduce the pressure sensation when the human body is in contact with the mattress.

[0072] Example 3

[0073] In this embodiment, as Figure 9-10 As shown, the mattress body 1 is cut from a porous elastic material. Several identical, stacked mattress bodies 1 can be cut from the porous elastic material. Between adjacent mattress bodies 1, the bottom support 22 of the upper mattress body 1 is embedded in the top groove 41 of the lower mattress body 1, and the top support 21 of the lower mattress body 1 is embedded in the bottom groove 42 of the upper mattress body 1.

[0074] Porous elastic materials can utilize high-density polyurethane foam, memory foam, high-resilience sponge, latex sponge, EVA foam, and other materials. These materials are precisely machined using CNC vibratory cutters, laser cutting tools, or specialized molds to create a complete structure of "support body 2 + intermediate body 3 + groove body 4" directly from a single piece of material, rather than through splicing or gluing. This integrated structure avoids gaps or adhesive layers at joints, ensuring a seamless connection between support body 2 and intermediate body 3. This results in more even force distribution under load, preventing support failure due to loosening at joints and extending the mattress's lifespan. Furthermore, material utilization is higher, and precision cutting optimizes the cutting path according to mattress dimensions, significantly improving material utilization and reducing costs.

[0075] Because the upper and lower mattress structures are cut from a single piece of material, the support 2 and groove 4 of the upper and lower mattress structures form an embedded complementary structure. The cross-sectional dimensions and spacing of the upper mattress bottom support 22 correspond perfectly to the cross-sectional dimensions and spacing of the lower mattress top groove 41; similarly, the dimensions of the lower mattress top support 21 also perfectly match the dimensions of the upper mattress bottom groove 42, ensuring no looseness or gaps during embedding. Furthermore, since the structure of each mattress body 1 is identical, it can be stacked in 2, 3, or even more layers, allowing users to freely combine them according to their needs for mattress thickness and firmness.

[0076] Example 4

[0077] This utility model also discloses an inflatable bed 5, such as Figure 11 As shown, it includes a cover 6, which wraps around any of the lightweight mattress structures described in the aforementioned embodiments, and the cover 6 is provided with an inflation valve 7.

[0078] The lightweight mattress structure serves as the internal skeleton of the air mattress 5. Its support body 2 and intermediate body 3 form a rigid support frame, bearing the main load-bearing function. The cover 6, as the outer wrapping material, can fix the internal mattress structure, prevent the stacked mattress body 1 from shifting, and form a sealed space. Working with the inflation valve 7, it allows for inflation and deflation, isolating the internal materials from the human body and improving comfort. The inflation valve 7 can adjust the firmness of the mattress by regulating the air pressure inside the cover 6. More air means a stronger constraint on the internal mattress structure, resulting in a firmer overall mattress; deflation reduces the constraint, making the mattress softer, thus meeting the different tactile needs of users.

[0079] More specifically, the cover fabric 6 includes a cover fabric 61, side walls 62 and a bottom fabric 63. The cover fabric 61 and side walls 62 are made of skin-friendly materials, and the bottom fabric 63 is made of TPU or PVC materials.

[0080] The cover fabric 61, side walls 62, and bottom fabric 63 work together to achieve the functions of wrapping and sealing. The cover fabric 61 is located on the upper surface of the air bed 5, and the side walls 62 are located on the circumferential side of the air bed 5. They are the parts that come into direct contact with the human body. Therefore, when implementing this, soft, breathable, and skin-friendly fabrics with low skin irritation can be used. Common fabrics include cotton fabrics, polyester fiber blends, and skin-friendly knitted fabrics. Composite materials are usually used, that is, the side that comes into contact with the human body is a skin-friendly fabric layer, and the side that comes into contact with the mattress body 1 is an airtight material, such as TPU and PVC, which facilitates the formation of a sealed inflation shape inside the air bed 5.

[0081] The bottom fabric 63 is located on the lower surface of the inflatable bed 5 and is in contact with the ground. It needs to be made of wear-resistant and non-slip material to prevent the bed from sliding or being scratched by sharp objects on the ground during use. Therefore, TPU composite material (polyurethane) or PVC composite material (polyvinyl chloride) can be selected. Both materials have good tensile properties, can expand to the design size when inflated, and have high tear resistance, which is suitable for the expansion and contraction requirements of the side walls 62 and the scratch protection requirements of the bottom fabric 63.

[0082] It should be noted that the cover fabric 61, side wall 62, and bottom fabric 63 can be a single integrated design with no physical separation between adjacent parts. For example, when transitioning from the cover fabric 61 to the side wall 62, it can be a smooth transition structure without sewn heat-pressed seams. Similarly, the transition between the side wall 62 and the bottom fabric 63 can also be a smooth transition structure without sewn heat-pressed seams.
