Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a strip-shaped airbag and a mattress. Background Technology

[0002] Existing strip-shaped airbag mattresses include a mattress body, a support layer within the mattress body, and an outer cover enclosing the support layer. The support layer contains a support bladder assembly and a control box for adjusting the air pressure within the support bladder assembly. The control box regulates the air pressure within the support bladder assembly, thereby adjusting the firmness of the mattress to meet the diverse needs of users. Existing support bladder assemblies include strip-shaped airbags arranged side-by-side and joined to form a support surface for supporting the user. Existing strip-shaped airbags increase their height to enhance vertical deformation and thus improve support comfort. However, this results in relatively high sidewalls for the airbags. Consequently, each height range of the sidewalls of the airbags undergoes significant expansion and deformation during inflation. This not only prevents the airbags from effectively raising their height and thus failing to provide effective support for the user, but also causes friction between the sidewalls of adjacent airbags, generating noise during inflation, deflation, or deformation under pressure, thus affecting the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a strip-shaped airbag and mattress with multi-layered reinforcing ribs. At least two vertically staggered reinforcing ribs are provided between the side walls of the airbag, so that each height range of the side wall of the airbag can be pulled and shaped by the corresponding reinforcing ribs. This not only ensures that the height of the airbag can be effectively increased after inflation, but also effectively prevents the side walls of adjacent airbags from rubbing against each other, effectively eliminates noise, and improves the user experience.

[0004] This invention is achieved through the following method: a strip-shaped airbag with multiple layers of reinforcing ribs, comprising a long strip-shaped airbag body, with reinforcing ribs spanning between the two side walls of the airbag body. The reinforcing ribs are at least two pieces and vertically staggered to limit the distance between the side walls of the airbag body. By providing at least two vertically staggered reinforcing ribs between the side walls of the airbag body, each height range of the side walls can be pulled and shaped by the corresponding reinforcing ribs. This ensures that the airbag can effectively increase its height after inflation, improving the sensitivity of the airbag's firmness adjustment, and also effectively prevents friction between the side walls of adjacent airbags, effectively eliminating noise caused by friction between corresponding side walls of adjacent airbags, thus improving the user experience.

[0005] Preferably, the bottom and top walls of the bladder are of equal width and both are wider than the width of the reinforcing rib, so that the bladder has a funnel shape that tapers inward from the center. By limiting the width of the reinforcing rib, the distance between the side walls of the bladder is limited, ensuring that the width of the middle part of the bladder is less than the width of the top and bottom surfaces. By limiting the deformation of the middle part of the side walls, the preset contour is maintained, thereby ensuring that the vertical support of the bladder can be flexibly adjusted. Setting the cross-sectional contour of the bladder to a funnel shape that tapers inward from the center effectively increases the distance between corresponding side walls of adjacent bladders, thereby preventing friction between the side walls and effectively eliminating the impact of noise on the user's sleep.

[0006] Preferably, the capsule includes an end face sheet and an annular rim sheet. The end face sheet covers the upper and lower ends of the rim sheet, so that the end face sheet and the rim sheet are bonded together to form the capsule. The end face sheet and the rim sheet are processed independently and bonded together by welding to form the capsule. This facilitates mass production of the end face sheet and the rim sheet, and reduces the amount of welding work by limiting the number of components, thereby improving assembly efficiency. The rim sheet is cylindrical and includes vertically aligned upper and lower ends. The end face sheet consists of two pieces, which respectively cover the upper and lower ends of the rim sheet and form a capsule isolated from the outside, ensuring that the air pressure inside the capsule is adjustable and effectively maintained.

[0007] Preferably, the edging sheet includes two parallel linear segments and an arc segment spanning the corresponding ends of the linear segments, with the tie rods arranged along the length of the linear segments. The linear segments facilitate adjacent side-by-side placement of the bladders, reducing gaps between adjacent bladders to ensure a smooth connection of the supporting surfaces, thus eliminating any foreign object sensation. The arc segments connect the linear segments, providing positioning and ensuring parallel arrangement. The tie rods between the linear segments ensure equal distances between them, maintaining a constant bladder profile, facilitating assembly and inflation / deflation, preventing friction between adjacent bladders due to excessive width expansion, and effectively reducing noise.

[0008] Preferably, the tie rods are rectangular sheets arranged parallel to each other. The two sides of each tie rod are bonded to corresponding linear segments, so that each area of ​​the bladder sidewall is pulled and limited by the tie rods, maintaining a uniform width. The tie rods are bonded along the length of the linear segments, ensuring that each area of ​​the linear segment can be effectively pulled, thus maintaining parallelism between the linear segments, effectively preserving the bladder's outline, and facilitating assembly and use. Corresponding tie rods are provided for each height range of the bladder sidewall to prevent excessive horizontal expansion in localized areas due to lack of tie rod support, ensuring that the width of each height range in the middle of the bladder is the same, effectively improving the reliability of the bladder's shape.

[0009] Preferably, the bladder body is divided into multiple chambers of equal height from top to bottom by the reinforcing ribs. These chambers are elongated and vertically stacked. By dividing the bladder body into multiple chambers, deformation is limited, thereby improving the shape stability of the bladder body and ensuring it maintains a predetermined contour. This effectively supports the user and prevents friction between adjacent chambers, effectively eliminating noise. The vertically stacked and interconnected chambers allow for adjustments to the bladder body's height through deformation, thus regulating its vertical stiffness. They also share an air source, ensuring synchronized air pressure regulation within each chamber.

[0010] Preferably, the bottom end face of the bladder is provided with an air nozzle that communicates with the outside. The bladders are arranged side by side, and the air nozzles are all located at the bottom end face of the same bladder. This not only facilitates the connection of the air nozzles in series and the synchronous adjustment of the bladder air pressure, but also effectively avoids the user and prevents the feeling of a foreign object.

[0011] Preferably, the length of the tie rod is less than the length of the capsule body. A through-hole is formed between the edge of the tie rod and the arc segment, allowing adjacent chambers to connect. This through-hole between the tie rod edge and the arc segment ensures that the air pressure in each chamber can be adjusted synchronously. The through-hole is located at the end of the capsule body, minimizing its impact on the capsule's shape retention. Its vertically continuous design ensures effective communication with all chambers, improving the synchronicity of air pressure adjustment.

[0012] Preferably, both the end face sheet and the edge sheet are made of multi-layered materials, which not only facilitates processing through stacking and bonding, improving processing efficiency, but also achieves composite functions and enhances the user experience.

[0013] A mattress includes a support layer and an outer cover enclosing the support layer. The support layer contains strip-shaped air chambers arranged side-by-side and joined together at their top surfaces to form a flat support surface. The side-by-side arrangement of the air chambers ensures that their top surfaces are at the same height and joined together to form a flat support surface. This effectively improves support comfort and allows for control of the firmness of the support surface by adjusting the air pressure within the air chambers, meeting diverse user needs and enhancing the user experience.

[0014] The beneficial effects of this utility model are as follows: At least two vertically staggered tie rods are provided between the side walls of the bladder, so that each height range of the side wall of the bladder can be pulled and shaped by the corresponding tie rods. This not only ensures that the height of the bladder can be effectively increased after inflation, improves the sensitivity of the bladder's softness and hardness adjustment, but also effectively prevents the side walls of adjacent bladders from rubbing against each other, effectively eliminates the noise caused by the friction between the corresponding side walls of adjacent bladders, and improves the user experience.

[0023] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1:

[0025] This embodiment provides a strip-shaped airbag with multiple layers of reinforcing ribs.

[0026] like Figure 1 and 2 The illustrated strip-shaped airbag includes a long, strip-shaped airbag body 1. Two tie rods 2 are strung across the two side walls of the airbag body 1, and these tie rods 2 are at least two in number and vertically staggered to limit the distance between the side walls of the airbag body 1. The presence of at least two vertically staggered tie rods 2 on the side walls of the airbag body 1 ensures that each height range of the side walls can be pulled and shaped by the corresponding tie rods 2. This not only ensures that the airbag body 1 can effectively increase in height after inflation, improving the sensitivity of the airbag body 1's firmness adjustment, but also effectively prevents friction between the side walls of adjacent airbag bodies 1, effectively eliminating noise caused by friction between corresponding side walls of adjacent airbag bodies 1, thus improving the user experience.

[0027] In this embodiment, the capsule 1 includes an end face sheet 3 and an annular surrounding sheet 4. The end face sheet 3 covers the upper and lower ends of the surrounding sheet 4, so that the end face sheet 3 and the surrounding sheet 4 are bonded together to form the capsule 1. The surrounding sheet 4 includes two parallel linear segments 5 and an arc segment 6 spanning the corresponding ends of the linear segments 5. The tie rod 2 is arranged along the length of the linear segments 5.

[0028] During installation, firstly, a rectangular substrate is rolled and bonded to form a rim sheet 4. The rim sheet 4 is then shaped to obtain the linear segment 5 and the arc segment 6. Next, tie rods 2 are inserted into the rim sheet 4 in sequence and welded and bonded to the corresponding height range. The tie rods 2 are attached and bonded along the corresponding linear segment 5 through their side edges, so that the tie rods 2 are arranged parallel to each other. Finally, the end face sheet 3 is covered on the upper and lower ends of the rim sheet 4 and welded to seal.

[0029] After installation, the end face sheet 3 and the surrounding sheet 4 are joined to form a sealed bladder 1. The tie rods 2 are set at each height range of the bladder 1. The tie rods 2 are used to pull and shape each height range of the bladder 1, ensuring that each height range of the bladder 1 will not expand outward due to inflation. This ensures that the bladder 1 can improve the height adjustment flexibility by limiting the width change when inflated, thereby improving the sensitivity of softness and hardness adjustment, and preventing the bladder 1 from affecting its support performance due to width expansion when subjected to vertical force.

[0030] In this embodiment, the bottom and top walls of the bladder 1 are of equal width and both are wider than the width of the tie rod 2, so that the bladder 1 is funnel-shaped with the center contracting inward. By setting the tie rod 2 with a smaller width, the distance between the side walls of the bladder 1 is limited, thereby making the bladder 1 funnel-shaped. By increasing the inward concavity of the side walls of the bladder 1, the distance between the corresponding side walls of adjacent bladder 1 is increased. When the top surfaces of adjacent bladder 1 are tightly fitted, a larger space can still be reserved between the side walls of adjacent bladder 1. This not only prevents friction between the side walls of bladder 1, effectively reducing noise, but also ensures that the top surfaces of adjacent bladder 1 are flat and fitted together, eliminating the feeling of foreign objects on the supporting surface.

[0031] In this embodiment, the tensioner 2 is rectangular and parallel to each other. The two sides of the tensioner 2 are respectively adhered to the corresponding linear segments 5, so that each area of ​​the sidewall of the capsule 1 is pulled and limited by the tensioner 2 and maintains a uniform width. The length of the tensioner 2 matches the length of the linear segments 5, allowing the side edges of the tensioner 2 to extend through the length of the linear segments 5. This ensures that each section of the linear segments 5 is subjected to the pulling force of the tensioner 2, thereby ensuring that the linear segments 5 on the sidewall of the capsule 1 maintain a parallel posture and improving the shaping effect of the capsule 1.

[0032] In this embodiment, the bladder 1 is divided by the tensioning tendon 2 into multiple chambers 7 arranged at equal heights from top to bottom (e.g., ...). Figure 4 As shown), the chambers 7 are elongated and vertically stacked. The length of the tie rod 2 is less than the length of the bladder body 1, and a through hole 8 is formed between the end edge of the tie rod 2 and the arc segment 6 to allow communication between adjacent chambers 7 (as shown). Figure 3 As shown), so that each chamber 7 is connected to the air nozzle 9 through the through hole 8. The chambers 7 are connected through the through hole 8 to ensure that the air pressure in each chamber 7 can be adjusted synchronously, to prevent the capsule 1 from having a difference in softness and hardness due to the air pressure difference between the chambers 7, and to ensure that the top surface of the capsule 1 can be vertically raised and lowered through the inflation and deflation operation.

[0033] In this embodiment, the bottom end face of the capsule 1 is provided with an air nozzle 9 that communicates with the outside. The air nozzle 9 is independently machined and assembled onto the capsule 1, which facilitates machining and assembly. An installation hole is opened at the bottom of the arc segment 6, through which the air nozzle 9 passes and is welded and bonded to ensure that the air nozzle 9 is fixedly connected to the capsule 1 and communicates with the through hole 8, thereby enabling synchronous adjustment of the air pressure in each chamber 7.

[0034] In this embodiment, both the end face sheet 3 and the edge sheet 4 are multi-layered materials. By setting materials with different functions, corresponding functions are obtained, thereby enabling the end face sheet 3 and the edge sheet 4 to have composite functions and improve the user experience.

[0035] In this embodiment, the number of the tension braces 2 can be adjusted adaptively according to the height of the bladder 1. When the number of tension braces 2 is three or more (e.g., Figure 5 and 6 As shown in the figure, the tie rods 2 are equidistantly placed within the surrounding sheet 4, and adjacent tie rods 2 have the same height difference, which should also be regarded as a specific implementation of this embodiment.

[0036] Example 2:

[0037] Compared to Embodiment 1, this embodiment provides a mattress.

[0038] like Figure 7 The mattress shown includes a support layer 10 and an outer cover 11 that surrounds the support layer 10. The support layer 10 contains strip-shaped airbags arranged side-by-side and joined together at their top surfaces to form a flat support surface. The side-by-side arrangement of the airbags ensures that their top surfaces are at the same height and joined together to form a flat support surface. This effectively improves support comfort and allows for control of the firmness of the support surface by adjusting the air pressure within the airbags, meeting diverse user needs and enhancing the user experience.

[0039] In this embodiment, the support bladder assembly is located in the middle of the support layer 10, which can provide effective support for the user and reduce production costs by limiting the number of bladders 1.

[0040] In this embodiment, the top surface of the support layer 10 is provided with a massage component. The massage component generates vertical deformation by inflating and deflating air, thereby applying a massage force to the user.

[0041] In this embodiment, the support layer 10 is provided with a device section, and the device section is provided with a control box. The air pressure of the support bladder group and the massage component is adjusted through the control box to obtain the corresponding functions and improve the user experience.

[0042] In this embodiment, the outer cover 11 can completely wrap the support layer 10, which not only protects the support layer 10, but also makes it easy to disassemble and replace the outer cover 11 and clean it, thus improving the user experience.

[0043] The other structures and effects of the strip-shaped airbag described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.
