Description

Technical Field

[0001] The present invention relates to the field of bedding, in particular to a strip-shaped air bag and a mattress. Background Art

[0002] Existing strip airbag mattresses include a cushion body, which is provided with a support layer and an outer cover that wraps the support layer. The support layer is provided with a support bag group and a control box for adjusting the support bag group. The control box adjusts the air pressure in the support bag group, thereby adjusting the softness and hardness of the cushion body to meet the differentiated usage needs of users. The existing support bag group includes strip airbags, which are arranged side by side and pieced together to form a support surface for supporting the user. Existing strip airbags increase the vertical deformation amplitude by increasing the height, thereby improving the support comfort. This results in the side walls of the strip airbags being higher, so that the middle part of the side wall of the strip airbag will undergo a large expansion deformation when the strip airbag is inflated. This not only makes it impossible to effectively raise the height of the strip airbags, thereby failing to provide effective support for the user, but also causes friction between the side walls of adjacent strip airbags, thereby generating noise during inflation or compression deformation, affecting the user experience. Summary of the Invention

[0003] In order to address the shortcomings of the existing technology, the present invention provides a strip airbag and mattress with built-in tie rods. The tie rods are arranged between the side walls of the bag body to limit the width of the middle part of the bag body, thereby ensuring that the bag body can effectively increase its height after inflation, reducing the inflation amount, and effectively preventing the side walls of adjacent bags from rubbing against each other, effectively eliminating noise, and improving the user experience.

[0004] The present invention is achieved in the following manner: a strip-shaped airbag with internal tie bars, comprising an elongated airbag body, with tie bars spanning the two side walls of the airbag body, the width of the tie bars being smaller than the width of the airbag body, so that the airbag body forms a funnel shape with its middle portion contracted inward. Tie bars are arranged between the side walls of the airbag body, and the tie bars act as a pull-limiting force on the middle portion of the side walls of the airbag body, so that the airbag body forms a funnel shape with its middle portion contracted inward after inflation. This not only ensures that the airbag body can effectively increase its height after inflation, improves the sensitivity of adjusting the airbag body's hardness, and enhances the effectiveness of support, but also reduces the amount of inflation while achieving the same support force, thereby increasing the adjustment speed. It also effectively prevents the side walls of adjacent airbags from rubbing against each other, effectively eliminating the noise generated by the friction between adjacent airbags, and improving the user experience.

[0005] Preferably, the bottom wall and top wall of the sac are set to have the same width and are both larger than the width of the tie rod. By limiting the width of the tie rod, the distance between the side walls of the sac is limited, ensuring that the width of the middle part of the sac is smaller than the width of the top and bottom surfaces of the sac. By limiting the deformation of the middle part of the side wall of the sac, the preset contour is maintained, thereby ensuring that the vertical support of the sac can be flexibly adjusted.

[0006] Preferably, the capsule includes an end face sheet and an annular edging sheet, wherein the end face sheet covers the upper and lower ports of the edging sheet, so that the end face sheet and the edging sheet are bonded together to form the capsule. The end face sheet and the edging sheet are processed independently and bonded together by welding to form the capsule, which not only facilitates batch processing of the end face sheets and the edging sheets, but also reduces the welding and bonding workload by limiting the number of components, thereby improving assembly efficiency. The edging sheet is cylindrical and tubular, including an upper and lower port aligned vertically. The end face sheet is composed of two pieces and covers the upper and lower ports of the edging sheet respectively and encloses a capsule isolated from the outside world, ensuring that the air pressure inside the capsule is adjustable and effectively maintained.

[0007] Preferably, the edge sheet includes two parallel linear segments and arc segments spanning the corresponding end edges of the linear segments. The tie bars are arranged along the length direction of the linear segments so that the bladder cavity in the bladder is divided into an upper cavity and a lower cavity that are interconnected. The linear segments are arranged to facilitate the adjacent and side-by-side arrangement of the bladders. The gaps between adjacent bladders are reduced to eliminate the foreign body sensation on the supporting surface. The arc segments are arranged to connect the linear segments, thereby positioning the linear segments and ensuring that the linear segments are arranged parallel to each other. Tie bars are arranged between the linear segments to ensure that the distance between the linear segments is the same, thereby maintaining a constant bladder contour, facilitating assembly and inflation and deflation, preventing friction between adjacent bladders due to excessive widthwise expansion, and effectively reducing noise. The upper cavity and the lower cavity are formed by separation to limit the deformation of the bladder, thereby ensuring that the bladder maintains the preset contour.

[0008] Preferably, the tie bars are rectangular sheets, with their side edges bonded to corresponding linear segments to ensure that all sections of the capsule have the same width. The side edges of the tie bars are bonded along the length of the linear segments, ensuring that all areas of the linear segments can be effectively pulled, thereby ensuring that the linear segments remain parallel, effectively maintaining the capsule contour, and facilitating assembly and use.

[0009] Preferably, the side edges of the tie bars are horizontally and continuously bonded to the midline of the linear segment, so that the upper and lower cavities have the same height. The tie bars are located in the middle of the bladder, ensuring that the upper and lower cavities are symmetrically arranged around the tie bars, ensuring balanced reception and preventing tilting or offsetting of the bladder.

[0010] Preferably, the length of the tie rod is shorter than the length of the bladder body, and the upper and lower cavities are connected through the end of the bladder body. A channel connecting the upper and lower cavities is formed by the area between the end edge of the tie rod and the arc segment, ensuring that the air pressure in the upper and lower cavities can be adjusted synchronously.

[0011] Preferably, the end face sheet and the edge sheet are both made of multi-layer materials, which is convenient for processing by stacking and bonding to improve processing efficiency, and can also obtain composite functions and enhance user experience.

[0012] Preferably, the end face of the bag is provided with an air nozzle connected to the outside world. The bags are arranged side by side, and the air nozzles are all arranged on the same end face of the bag. This is convenient for connecting the air nozzles in series and synchronously adjusting the air pressure of the bag, and it can also effectively avoid the user to prevent the sensation of foreign body.

[0013] A mattress comprises a support layer and an outer cover enclosing the support layer. The support layer is provided with strip-shaped air cells, which are arranged side by side and joined together at their top surfaces to form a flat support surface. The side-by-side arrangement of the strip-shaped air cells ensures that their top surfaces are of equal height and join together to form a flat support surface. This effectively improves support comfort and allows the softness and hardness of the support surface to be controlled by adjusting the air pressure within the strip-shaped air cells, thereby meeting the differentiated needs of users and enhancing the user experience.

[0014] The beneficial effects of the present invention are as follows: tie bars are arranged between the side walls of the sac, which play a pulling and limiting role on the middle part of the side wall of the sac, so that the sac forms a funnel shape with the middle part shrinking inward after inflation. This ensures that the sac can effectively increase its height after inflation, improves the sensitivity of adjusting the hardness of the sac, and improves the support effectiveness. It can also reduce the inflation amount while achieving the same supporting force, increase the adjustment speed, and effectively prevent the side walls of adjacent sacs from contacting and rubbing against each other, effectively eliminate the noise generated by the contact and friction between adjacent sacs, and improve the user experience.

[0020] The essential features of the present invention are further described below with reference to the accompanying drawings and specific implementation methods.

[0021] Example 1:

[0022] This embodiment provides a strip-shaped airbag with internal tensioning bars.

[0023] like Figure 1The strip-shaped airbag shown includes an elongated bladder body 1, with tie bars 2 spanning the two side walls of the bladder body 1. The width of the tie bars 2 is smaller than that of the bladder body 1, so that the bladder body 1 forms a funnel shape with its middle portion contracting inward. Tie bars 2 are provided between the side walls of the bladder body 1, and the tie bars 2 act as a pull limiter on the middle portion of the side walls of the bladder body 1, so that the bladder body 1 forms a funnel shape with its middle portion contracting inward after inflation. This not only ensures that the bladder body 1 can effectively increase its height after inflation, improves the sensitivity of the bladder body 1 hardness adjustment, and enhances the effectiveness of support, but also reduces the amount of inflation while achieving the same support force, thereby increasing the adjustment speed. It also effectively prevents the side walls of adjacent bladder bodies 1 from rubbing against each other, effectively eliminating the noise generated by the friction between adjacent bladder bodies 1, and improving the user experience.

[0024] In this embodiment, the capsule 1 includes an end sheet 3 and an annular edge sheet 4 (such as Figure 3 As shown), the edge sheet 4 includes two parallel linear segments 5 and an arc segment 6 spanning the corresponding end edges of the linear segments 5. The linear segments 5 and the arc segments 6 are alternately connected and enclosed to form a ring. The tie rod 2 is arranged along the length direction of the linear segment 5. Specifically, the tie rod 2 is in the shape of a rectangular sheet, and the two side edges of the tie rod 2 are respectively adhered to the corresponding linear segments 5, so that each section of the capsule 1 has the same width.

[0025] During installation, the two side edges of the tie bars 2 are welded and bonded to the centerline of the corresponding linear segments 5. The end panels 3 are overlaid on the upper and lower ends of the edge panels 4 and bonded together by peripheral welding. Once installed, the end panels 3 and edge panels 4 enclose a sealed bladder 1. The tie bars 2 are positioned in the middle of the bladder 1, shaping the middle portion of the bladder 1 to prevent it from expanding outwards due to inflation. This ensures that the bladder 1 can improve height adjustment flexibility by limiting width changes during inflation, thereby increasing the sensitivity of hardness adjustment and preventing widthwise expansion of the bladder 1 when subjected to vertical forces, which could affect support performance.

[0026] In this embodiment, the end sheet 3 covers the upper and lower ends of the edge sheet 4, so that the end sheet 3 and the edge sheet 4 are bonded together to form the bladder 1. The end sheet 3 is flat, and the edge sheet 4 is cylindrical and tubular. The contour of the end sheet 3 is the same as the contour of the upper and lower ends of the edge sheet 4. It not only serves to block the upper and lower ends of the edge sheet 4, improving the sealing performance of the bladder 1, but also serves to limit expansion and deformation of the top and bottom of the bladder 1, ensuring a constant contour of the bladder 1 and allowing the height and support hardness of the bladder 1 to be adjusted by inflation and deflation.

[0027] In this embodiment, the bottom and top walls of the bladder 1 are of equal width and both are greater than the width of the tie bars 2. This not only improves the support stability of the bladder 1 by increasing the width of the bottom wall 1, preventing it from tilting or falling, but also reduces the gap between the top surfaces of adjacent bladders 1 by increasing the width of the top wall 1, thereby improving the flatness of the support surface and ensuring that all areas of the support surface are supported by the bladder 1. Furthermore, the tie bars 2 limit the deformation amplitude of the middle portion of the bladder 1 sidewalls, thereby preventing friction between the sidewalls of adjacent bladders 1, effectively eliminating friction noise and improving the user experience. Furthermore, the width of the middle portion of the bladder 1 is smaller than the width of the bottom and top surfaces of the bladder 1, resulting in less deformation resistance in the middle portion of the bladder 1. This allows the top and bottom surfaces of the bladder 1 to assume different angles by twisting the middle portion of the bladder 1. This ensures that the bottom surface of the bladder 1 remains level and provides effective support for the top surface of the bladder 1, while also ensuring that the top surface of the bladder 1 can swing to conform to a non-horizontal surface of the user, thereby improving support comfort.

[0028] In this embodiment, the cavity in the bladder body 1 is divided into an upper cavity 7 and a lower cavity 8 (such as Figure 2 (As shown). The upper and lower chambers 7 and 8 are connected by a channel at the end of the bladder 1, ensuring that they share a common air nozzle 9 and achieve synchronized air pressure regulation. This ensures that the bladder 1 can be raised and lowered vertically while minimizing tilt, providing vertical force for the user. The side edges of the tie bars 2 are continuously horizontally bonded to the centerline of the linear segment 5, ensuring that the upper and lower chambers 7 and 8 have the same height, ensuring that they exhibit similar mechanical properties, thereby improving the synchronization of deformation at the top and bottom of the bladder 1.

[0029] In this embodiment, the length of the tie rod 2 is smaller than the length of the bladder 1, and the upper cavity 7 and the lower cavity 8 are connected through the end of the bladder 1, ensuring that the tie rod 2 can completely cover the linear segment 5, and the width limiting effect of the middle part of the bladder 1 is improved by increasing the welding adhesion length. A channel for connecting the upper cavity 7 and the lower cavity 8 can also be formed between the end edge of the tie rod 2 and the arc segment 6, ensuring that the air pressure in the upper cavity 7 and the lower cavity 8 are synchronously adjusted, and the synchronization is improved by increasing the cross-sectional area of the channel.

[0030] In this embodiment, the end sheet 3 and the edge sheet 4 are both made of multi-layer materials. By setting materials with different functions to obtain corresponding functions, the end sheet 3 and the edge sheet 4 have composite functions, thereby improving the user experience.

[0031] In this embodiment, the end surface of the bladder body 1 is equipped with an air nozzle 9 for communication with the outside world. The air nozzle 9 is independently machined and assembled on the bladder body 1, facilitating processing and assembly. A mounting hole is provided at the bottom of the arc segment 6, through which the air nozzle 9 is passed and welded. This ensures that the air nozzle 9 is firmly attached to the bladder body 1 and communicates with the lower chamber 8, thereby enabling synchronous regulation of the air pressure in the upper and lower chambers 7 and 8. The air nozzle 9 is preferably located at the bottom or middle of the end surface.

[0032] Example 2:

[0033] Compared with the first embodiment, this embodiment provides a mattress.

[0034] like Figure 4 The mattress shown includes a support layer 10 and a cover 11 encasing the support layer 10. The support layer 10 is provided with strip-shaped air cells arranged side by side and joined together to form a flat support surface. The side-by-side arrangement of the strips ensures that their top surfaces are of equal height and join together to form a flat support surface. This not only effectively improves support comfort, but also allows the softness and hardness of the support surface to be controlled by adjusting the air pressure within the strips, meeting the diverse needs of users and enhancing the user experience.

[0035] In this embodiment, the support bladder group is arranged in the middle of the support layer 10, which can not only provide effective support for the user, but also reduce production costs by limiting the number of bladders 1.

[0036] In this embodiment, a massage component is provided on the top surface of the support layer 10. The massage component generates vertical deformation by inflation and deflation, thereby applying a massage force to the user.

[0037] In this embodiment, a device portion is provided in the support layer 10, and a control box is provided in the device portion. The air pressure of the support bag group and the massage component is adjusted through the control box to obtain corresponding functions and enhance the user experience.

[0038] In this embodiment, the outer cover 11 can completely wrap the support layer 10, which not only plays a role in wrapping and protecting the support layer 10, but also makes it easy to disassemble and replace the outer cover 11, and clean the outer cover 11, thereby improving the user experience.

[0039] The other structures and effects of the strip-shaped airbag described in this embodiment are consistent with those in the first embodiment and will not be described in detail.
