Description

Technical Field

[0001] The present invention relates to the technical field of inflatable products, and more particularly to an inflatable mattress Background Art

[0002] An inflatable mattress is a mattress that has strong flexibility and elasticity and expands in volume after being inflated. It has the beneficial effects of not being easily deformed, being comfortable and easy to carry, and is deeply loved by people.

[0003] The inflatable mattresses currently on the market generally have the following shortcomings: first, poor air permeability. People sleeping on them for a long time will feel stuffy and uncomfortable, and long-term moisture will have adverse effects on human health; second, the noise is relatively loud. When the user turns over in bed, the inflatable mattress will also make noise, which will affect the user's sleep; third, the mattress is prone to expand into irregular shapes after inflation, affecting the use effect.

[0004] On the other hand, to maintain the desired shape of an air mattress when inflated, drawstrings are typically installed within the air chamber. Traditional drawstrings connect the top and bottom sheets of the air mattress vertically. When the air mattress is inflated, the drawstrings exert vertical tension on the top and bottom sheets. However, air mattresses with this structure have the following drawstrings: First, the seam connecting the drawstrings to the top or bottom sheet is subject to concentrated force, which can easily cause the drawstrings to break or tear at the joint; second, they can easily cause the mattress to partially collapse or tilt upward, making it unstable, impacting performance and lifespan. Summary of the Invention

[0005] The present invention aims to overcome at least one of the defects of the above-mentioned prior art and provide an inflatable mattress to solve the problems of loud noise, poor air permeability, easy sliding during use, discomfort and excessive expansion and deformation of the inflatable mattress.

[0006] The technical solution adopted by the present invention is an inflatable mattress, comprising a mattress body enclosed by a top surface, a bottom surface and side surfaces, the top surface of the mattress body being formed by laminating a flocking layer and a PVC / TPU layer, and the bottom surface and / or side surfaces of the mattress body being formed by laminating a fabric layer and a PVC / TPU layer.

[0007] Among them, the flocking layer on the top surface is arranged on the outside of the PVC / TPU layer, the fabric layer on the bottom surface and / or the side surface is arranged on the outside of the PVC / TPU layer, and the PVC / TPU layers between the top surface and the side surface, and the bottom surface and the side surface are welded or bonded to each other to form a mattress structure.

[0008] In this technical solution, the top surface of the mattress body corresponds to the side on which the user lies flat, and the bottom surface corresponds to the side in contact with the ground. By arranging a flocking layer on the top surface of the mattress body, the noise generated by the friction between the PVC material and the human body can be reduced. In addition, flocking on the top surface of the mattress body can make the inflatable mattress more delicate and breathable, giving people a more comfortable feeling when in contact with human skin, and improving the comfort of use.

[0009] The bottom and at least one side of the mattress body are formed by laminating a fabric layer and a PVC / TPU layer. The fabric layer can reduce the noise generated when the mattress is touched, avoid cracking, and increase the service life of the mattress body.

[0010] Furthermore, conventional mattresses tend to expand into an arc shape after inflation, creating a loaf-like appearance. This makes the mattress less flat and aesthetically pleasing, shortening its lifespan. The fabric layer, however, limits the expansion of the PVC / TPU layer, resulting in a smoother, more aesthetically pleasing mattress. This prevents deformation and increases the mattress's hardness, providing greater comfort. It also prevents cracking and extends its lifespan.

[0011] Among them, preferably, the bottom and side surfaces of the mattress body are formed by laminating a fabric layer and a PVC / TPU layer. The fabric layer can reduce the noise generated when the mattress is touched, improve its toughness, avoid cracking, and improve the comfort and service life of use.

[0012] Furthermore, the PVC hardness value of the bottom surface of the mattress body is greater than the PVC hardness value of the top surface of the mattress body.

[0013] Further preferably, the hardness of the PVC on the side of the mattress body is consistent with the hardness of the PVC on the bottom of the mattress body.

[0014] Furthermore, at least the bottom surface of the mattress body is formed by laminating a fabric layer and a PVC / TPU layer, the PVC hardness of the top surface structural layer of the mattress body is 35-45 PHR, and the PVC hardness of the bottom surface structural layer of the mattress body is 55-75 PHR.

[0015] In the present technical solution, since the top and bottom / side structural layers are different, and the PVC hardness value of the top structural layer is lower than that of the bottom structural layer, that is, the top surface has greater elasticity, in order to further maintain the flatness and aesthetic performance of the mattress body and avoid the formation of bread-like protrusions on the surface of the mattress body, the PVC hardness of the PVC / TPU layer on the top surface of the mattress body is adjusted to between 35 and 45 PHR, preferably 40 PHR, so as to better match the PVC hardness and elasticity of the bottom / side structural layer.

[0016] A higher PHR value indicates a softer PVC, resulting in a greater expansion coefficient and greater elasticity, making the mattress more susceptible to deformation. Conversely, a lower PHR value indicates a smaller elasticity and less deformation. Traditional PVC mattresses typically require a PHR between 50 and 56 to achieve a balance between expansion coefficient and elasticity.

[0017] The parameter PHR represents the number of parts of rubber or resin added to every 100 parts (by mass) of PVC material, indirectly indicating the hardness of the PVC. The PHR value can be measured using a Rockwell hardness tester.

[0018] In this technical solution, the top flocking layer is made of fiber fleece, which does not affect the PVC's elasticity when bonded to it. The bottom fabric layer, on the other hand, has little or no elasticity, and forms a single unit with the PVC when bonded. Therefore, the fabric acts as a restraint, limiting the PVC's expansion and deformation, thereby restricting the mattress's expansion and deformation. The PVC hardness of the bottom bonding layer is adjusted to 55-75 PHR, and further adjusted to 60-70 PHR. This not only softens the PVC hardness of the bottom bonding layer but also prevents deformation, providing a more comfortable feel during use and better meeting user needs.

[0019] Furthermore, an upper filling piece is provided at the connection between the top surface and the side surface of the mattress body, and a lower filling piece is provided at the connection between the bottom surface and the side surface of the mattress body.

[0020] In this technical solution, the mattress body is formed into a rectangular parallelepiped by the top, side, and bottom surfaces. The upper and lower patch panels are respectively arranged within the space enclosed by the mattress body. The upper patch panels are located around the connection between the top and side surfaces, and the lower patch panels are located around the connection between the bottom and side surfaces, forming the upper and lower edges of the mattress body. The upper edge is higher than other parts of the top surface, which can intercept and limit the quilt, effectively preventing it from slipping, and also preventing the user from sliding off the mattress while sleeping. The lower edge increases the friction between the mattress and the bottom surface, giving the mattress body greater grip and a more stable grip, providing an anti-slip effect and improving user comfort.

[0021] In this technical solution, the PVC / TPU layers on the top, bottom, and sides are all located on the inside, while the flocking / fabric layer is located on the outside, resulting in better noise reduction. Furthermore, the connections between the top and side surfaces, as well as between the bottom and side surfaces, are first made through the PVC / TPU layer, ensuring airtightness and toughness at the joints, enhancing the mattress's stability.

[0022] Welding methods include high-frequency and hot-melt bonding, and lamination includes gluing or molding. The top, bottom, and side surfaces of the mattress body are connected by hot-melt bonding or adhesive bonding. The PVC / TPU and flocking layers, as well as the PVC / TPU and fabric layers, are bonded by gluing, hot-melt bonding, or molding.

[0023] Furthermore, the upper and lower patching material four-pieces are made of PVC / TPU material, and the PVC / TPU sheets are sequentially welded end to end or attached to form a rectangular shape.

[0024] Furthermore, the upper and lower patch panels are arranged in the space enclosed by the mattress body, and the connection position of the upper patch panel with the top surface is higher than the connection position with the side surface, and the connection position of the lower patch panel with the bottom surface is lower than the connection position with the side surface.

[0025] The arrangement of the upper and lower filling pieces can make the mattress body more flat and stable as a whole.

[0026] Furthermore, a plurality of drawstrings are provided in the space enclosed by the side surfaces, and the drawstrings are respectively connected to the top surface and the bottom surface of the mattress body.

[0027] By setting the drawstring, the three-dimensional sense and hardness of the inflatable mattress are improved, making the mattress flatter after inflation.

[0028] Furthermore, the drawstring is at least partially arranged obliquely in the space enclosed by the mattress body, and on the same cross section, an extension line of the obliquely arranged drawstring intersects with an extension line of the side surface.

[0029] The inclination of the drawstring adjusts the force on the bottom and top surfaces of the mattress body, making the force more balanced. Since the force position on the upper side and the force position on the lower side of the drawstring are not on the same vertical line, the top and bottom surfaces of the mattress body can be flatter and more stable.

[0030] In this technical solution, since the structural layers of the top and bottom / side surfaces of the mattress body are inconsistent, the stress level, expansion level, PVC hardness, etc. of the top surface relative to the bottom / side surfaces are also different. The inclined setting of the pull strap can better match the stress conditions of different surfaces, making the stress between the top surface and the ground / side surfaces more balanced. At the same time, it can also adjust the flatness of the top and bottom / side surfaces, so that the stress of the mattress body is more balanced, and the stability and aesthetics are better.

[0031] Furthermore, the angle α formed by the drawstring and the bottom surface of the mattress body is in the range of 60 degrees < α ≤ 90 degrees.

[0032] Furthermore, the drawstrings form a smaller angle with the bottom surface of the mattress body as they extend from the center of the mattress body toward the head and tail edges. The drawstrings are arranged within the space enclosed by the mattress body, with the angle decreasing toward the head and tail edges, tending toward 60 degrees; and increasing toward the center, tending toward 90 degrees.

[0033] The PVC of the top structural layer of this technical solution has low hardness and high elasticity, while the bottom or side structural layers, due to the addition of a patch layer, have little or no elasticity. Therefore, the drawstring is tilted to better accommodate the difference in elasticity between the top and bottom surfaces. To better adapt to the hardness of the PVC on the top surface of the mattress body, the angle α formed by the drawstring and the bottom surface of the mattress body is within the range of 60 degrees < α ≤ 90 degrees.

[0034] Among them, the oblique pulling of the drawstrings in this technical solution does not only stagger the forces on the top and bottom surfaces of the drawstrings, but also makes the forces on the drawstrings not in a unified direction. By tilting the drawstrings and pulling each other, the forces that offset each other are generated to achieve the balance of the force surfaces. The drawstrings gradually tilt outward from the middle toward the head and tail of the mattress body, so that the top surface of the mattress achieves a flat effect after inflation.

[0035] Furthermore, with the midline of the long side of the mattress body as the axis of symmetry, when the number of drawstrings is even, the drawstrings are symmetrically and obliquely arranged in the space formed around the axis of symmetry of the mattress body; when the number of drawstrings is odd, one group of drawstrings is arranged in the space where the axis of symmetry of the mattress body is located, which is perpendicular to the bottom and top surfaces of the mattress body, and the drawstrings other than the axis of symmetry are symmetrically and obliquely distributed in the space formed around the axis of symmetry of the mattress body.

[0036] Furthermore, the drawstring is gradually inclined outward from the top surface of the mattress body to the bottom surface of the mattress body.

[0037] The drawstring is gradually inclined outward from the top surface of the mattress body to the bottom surface of the mattress body, that is, the support position of the drawstring on the top surface of the mattress body is close to the middle of the mattress body, and the support position of the drawstring on the bottom surface of the mattress body is far away from the middle of the mattress body, so that the mattress body has a more stable grip and is not easy to tip over, with the beneficial effect of being more stable and flatter.

[0038] Furthermore, the fabric layer is made of nylon or polyester or polyester-cotton blended fabric or cotton cloth or mesh cloth.

[0039] Furthermore, the drawstring has a sheet-like, column-like or ring-like structure. The sheet-like drawstring is arranged along the inner circumference of the mattress body and is designed to be curved or straight at the connection between the top / bottom surfaces of the mattress body; the column-like or ring-like drawstring is evenly arranged in the space of the mattress body and arranged in a certain pattern or shape.

[0040] Among them, the top / bottom of the sheet-like structure of the pull strap is designed in a straight line or a wavy shape, which makes the force more balanced and the appearance better.

[0041] The columnar structure of the pull strap is more stable and can also achieve the beneficial effect of evenly distributing force on the top and bottom surfaces and improving the aesthetics.

[0042] Among them, the columnar structure pull straps include cylindrical pull straps, 8-shaped pull straps or honeycomb pull straps, etc.; the pull straps of this technical solution are not limited to the above structural designs, and can also be other design styles, such as pull straps with annular structures.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] This technical solution effectively reduces the noise of the mattress body and improves the user's sleep quality and usage effect by arranging the bottom and at least one side of the mattress body to be formed by laminating a fabric layer and a PVC / TPU layer. It also reduces the irregular expansion rate of the mattress body, making the mattress body flatter and less prone to deformation and cracking, and increases the hardness of the mattress body, thereby improving the comfort and service life of the user.

[0045] This technical solution sets the drawstring at an angle so that the force points on the top and bottom surfaces of the same drawstring are staggered, making the force on the top and bottom surfaces more balanced, and greatly reducing the bread-like bulge of the mattress surface and the surrounding area, making the mattress body more beautiful; at the same time, the drawstring is set to gradually tilt outward from the top surface to the bottom surface, and the inclination angle from the center to the outside is increased, so that the bottom surface of the mattress has a more stable grip on the ground, ensuring the stability and flatness of the mattress body.

[0046] This technical solution improves the problem of loud noise and airtightness on the top surface of the inflatable bed by adopting a structural layer design of a flocking layer and a PVC / TPU layer laminated together on the top surface of the mattress body. At the same time, the bottom and / or side surfaces of the mattress body adopt a structural layer design of a fabric layer and a PVC / TPU layer laminated together, which can effectively improve the problem of local bread-shaped bulges and expansion deformation of traditional inflatable beds after inflation, making the mattress body flatter. At the same time, the fabric layer can also effectively reduce the risk of the mattress body being scratched, abraded or punctured, thereby increasing the service life of the mattress body.

[0070] The accompanying drawings are for illustrative purposes only and are not to be construed as limiting the present invention. To better illustrate the following embodiments, some components in the accompanying drawings may be omitted, enlarged, or reduced in size, and do not represent actual product dimensions. Those skilled in the art will appreciate that some well-known structures and their descriptions may be omitted from the accompanying drawings.

[0071] Example 1

[0072] like Figure 1 and Figure 13 As shown, an air mattress includes a mattress body surrounded by a top surface 110, a bottom surface 120 and side surfaces 130.

[0073] like Figure 3 As shown, the top surface 110 of the mattress body is formed by laminating a flocking layer B and a PVC layer A.

[0074] like Figure 4 As shown, the bottom surface 120 and the side surface 130 of the mattress body are formed by laminating a fabric layer C and a PVC layer A.

[0075] Among them, Figure 1 As shown, the top surface 110 of the mattress body corresponds to the side on which the user lies flat, and the bottom surface 120 corresponds to the side in contact with the ground. In addition, a flocking layer B is provided on the top surface 110 of the mattress body, which can reduce the noise generated by the friction between the PVC material and the human body, and can make the inflatable mattress more delicate and breathable, giving people a more comfortable feeling when in contact with human skin, and improving the comfort of use.

[0076] The bottom surface 120 and the side surface 130 of the mattress body are formed by laminating a fabric layer C and a PVC layer A. The fabric layer C can reduce the noise generated when the mattress is touched, improve its toughness, avoid cracking, and improve the comfort and service life of the mattress.

[0077] In addition, the provision of the fabric layer C limits the expansion of the PVC layer A, making the mattress body smoother and more beautiful, and increasing the hardness of the mattress body, making the mattress body more comfortable.

[0078] Wherein, the fabric layer C is made of nylon.

[0079] like Figure 1 and Figure 2 As shown, an upper filling piece 210 is provided at the connection between the top surface 110 and the side surface 130 of the mattress body, and a lower filling piece 220 is provided at the connection between the bottom surface 120 and the side surface 130 of the mattress body.

[0080] like Figures 5 to 8 As shown, in this technical solution, the mattress body is enclosed by the top surface 110, the side surface 130 and the bottom surface 120 to form a rectangular parallelepiped shape. The upper patch sheet 210 and the lower patch sheet 220 are respectively arranged in the space enclosed by the mattress body, and the upper patch sheet 210 is located around the connection of the top surface 110 and the side surface 130, and the lower patch sheet 220 is located around the connection of the bottom surface 120 and the side surface 130, forming the upper and lower edges of the mattress body. Among them, the upper edge is higher than other positions of the top surface 110, which can play a role of interception and limitation, effectively preventing the quilt from slipping, and also preventing the user from slipping off the mattress when sleeping. The setting of the lower edge increases the friction between the mattress and the bottom surface 120, making the mattress body have greater grip and more stable grip, thereby improving the comfort of use.

[0081] The upper and lower patching material four-pieces 210 and 220 are made of PVC material, and are formed into a rectangular shape by welding the PVC sheets end to end in sequence.

[0082] like Figures 3 and 4 As shown, the flocking layer B of the top surface 110 is arranged on the outside of the PVC layer A, the fabric layer C of the bottom surface 120 and / or the side surface 130 is arranged on the outside of the PVC layer A, and the PVC layers A between the top surface 110 and the side surface 130 and the bottom surface 120 and the side surface 130 are welded to each other to form a mattress structure.

[0083] The PVC layer A of the top surface 110, bottom surface 120, and side surface 130 is located on the inside, while the flocking layer B / fabric layer C is located on the outside, which improves noise reduction. Furthermore, the connection between the top surface 110 and the side surface 130, as well as the connection between the bottom surface 120 and the side surface 130, is first welded by welding the PVC layer A to the PVC layer A, ensuring the airtightness and toughness of the joints, thereby enhancing the stability of the mattress.

[0084] The top surface 110, the bottom surface 120 and the side surface 130 are sealed by hot melt welding. The PVC layer A and the flocking layer B, as well as the PVC layer A and the fabric layer C, are bonded by adhesive bonding, hot melt bonding or low temperature compression molding.

[0085] like Figure 1 、 Figure 11 and Figure 12 As shown, a plurality of drawstrings 300 are provided in the space enclosed by the side surfaces 130 .

[0086] like Figure 9 and Figure 10 As shown, the drawstrings 300 are respectively connected to the top surface 110 and the bottom surface 120 of the mattress body.

[0087] By providing the drawstring 300 , the three-dimensional effect and hardness of the air mattress are enhanced, and the mattress is made flatter after being inflated.

[0088] like Figures 5 to 8 As shown, the upper patch sheet 210 and the lower patch sheet 220 are arranged in the space enclosed by the mattress body, and the connection position of the upper patch sheet 210 with the top surface 110 is higher than the connection position with the side surface 130, and the connection position of the lower patch sheet 220 with the bottom surface 120 is lower than the connection position with the side surface 130.

[0089] The arrangement of the upper filling material four-piece piece 210 and the lower filling material four-piece piece 220 can make the mattress body as a whole more flat and stable.

[0090] like Figure 11 and Figure 12 As shown, the drawstring 300 is at least partially tilted and arranged in the space enclosed by the mattress body.

[0091] The drawstring 300 is tilted to adjust the force on the bottom surface 120 and the top surface 110 of the mattress body, making the force more balanced. Since the force position on the upper side and the force position on the lower side of the drawstring 300 are not on the same vertical line, the top surface 110 and the bottom surface 120 of the mattress body can be flatter and more stable.

[0092] The drawstring 300 is gradually inclined outward from the top surface 110 of the mattress body to the bottom surface 120 of the mattress body.

[0093] The drawstring 300 gradually tilts outward from the top surface 110 of the mattress body to the bottom surface 120 of the mattress body, that is, the contact position of the drawstring 300 on the top surface 110 of the mattress body is close to the middle of the mattress body, and the contact position of the drawstring 300 on the bottom surface 120 of the mattress body is away from the middle of the mattress body, so that the mattress body has a more stable grip and is not easy to tip over, which has the beneficial effect of being more stable and flatter.

[0094] like Figure 12 and Figure 13 As shown, the drawstring 300 is of sheet-like design, and the connection position between the drawstring 300 and the top surface 110 and the bottom surface 120 is wavy, and the top surface 110 and the bottom surface 120 of the mattress body are wavy.

[0095] The inclination angle formed by the drawstring 300 and the bottom surface 120 of the mattress body is in the range of 60 degrees < α ≤ 90 degrees.

[0096] The drawstring 300 forms a smaller angle with the bottom surface 120 of the mattress body as it extends from the center of the mattress body toward the head and tail ends. The drawstring 300 is positioned within the space enclosed by the mattress body. The angle decreases toward the head and tail ends of the mattress body, approaching 60 degrees. The angle increases toward the center of the mattress body, approaching 90 degrees.

[0097] Example 2

[0098] like Figures 14 and 15 As shown, the difference between this embodiment and embodiment 1 is that the drawstring 300 is a sheet-shaped design, and the connection position between the drawstring 300 and the top surface 110 and the bottom surface 120 is a straight line, and the top surface 110 and the bottom surface 120 of the mattress body have straight lines.

[0099] Example 3

[0100] like Figures 16-19 As shown, the difference between this embodiment and embodiment 1 is that the drawstring 300 of this embodiment is designed in an 8-shape, and the 8-shaped drawstring 300 is tilted in the space enclosed by the mattress body and is respectively connected to the top surface 110 and the bottom surface 120 of the mattress body.

[0101] The connection position between the drawstring 300 and the top surface 110 and the bottom surface 120 is in an 8-shape, and the top surface 110 and the bottom surface 120 of the mattress body are in an 8-shaped pattern.

[0102] Example 4

[0103] like Figures 20-23 As shown, the difference between this embodiment and embodiment 1 is that the drawstring 300 of this embodiment is cylindrical in design. The cylindrical drawstring 300 is tilted in the space enclosed by the mattress body and is respectively connected to the top surface 110 and the bottom surface 120 of the mattress body.

[0104] The connection positions between the drawstring 300 and the top surface 110 and the bottom surface 120 are circular, and the top surface 110 and the bottom surface 120 of the mattress body are circular in texture.
