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 bladder group and a control box that adjusts the support bladder group. The control box adjusts the air pressure within the support bladder group, thereby adjusting the softness and hardness of the cushion body to meet the user's differentiated usage needs. The existing support bladder group includes strip airbags, which are arranged side by side and assembled to form a support surface for supporting the user. The strip airbags are formed by gluing end sheet material and edge sheet material together. The edge sheet material is cylindrical and tubular. Because it is annular and is formed by curling and gluing long strips of sheet material, the length of the sheet material must reach the circumference of the edge sheet material, which increases the difficulty and cost of raw material supply and affects 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 a spliced substrate. The edge sheet is formed by gluing two substrates of the same length together. This not only reduces the requirement for substrate length by increasing the number of substrates, thereby facilitating the supply of raw materials and reducing costs, but also facilitates batch preparation of raw materials by using substrates of the same length, thereby improving the user experience.

[0004] The present invention is achieved through the following method: a strip-shaped airbag with a spliced substrate, comprising an elongated airbag body, the airbag body comprising end face sheets and an annular edge sheet, the end face sheets covering the upper and lower ends of the edge sheet, the end face sheets and the edge sheet being bonded together to form the airbag body, the edge sheet being formed by bonding two elongated substrates of the same length to shorten the substrate length. The end face sheets are bonded and welded to the upper and lower ends of the edge sheet to form the airbag body, and the edge sheet is formed by bonding two substrates of the same length. This not only reduces the substrate length requirement by increasing the number of substrates, thereby facilitating raw material supply and reducing costs, but also facilitates batch preparation of raw materials by using substrates of the same length, improving the user experience.

[0005] Preferably, the corresponding end edges of adjacent substrates are flattened and bonded together via a connecting piece, thereby sealing the adjacent substrate end edges together. Flattening the corresponding end edges of the substrates and bonding them together via the connecting piece ensures a constant circumferential length of the edge sheet, preventing variations in circumferential length of the edge sheet due to different overlapping lengths when bonding the substrate ends. Furthermore, the corresponding end edges of the substrates are aligned and abutted, ensuring that the edge sheets have a uniform circumference, facilitating production.

[0006] Preferably, the connecting sheet is in the form of an elongated strip, and its length matches the length of the substrate edges, so that the connecting sheet completely blocks the gap between the corresponding edges of adjacent substrates. The connecting sheet can completely cover the gap between the adjacent substrate edges, ensuring a sealed connection between the substrate edges and preventing air leakage from the capsule.

[0007] Preferably, the edge sheet includes two parallel linear segments and an arc segment spanning the corresponding end edges of the linear segments, and the connecting piece is provided at the junction of the arc segment and the linear segment. Each substrate includes a linear segment and an arc segment. The linear segment is provided to facilitate the side-by-side arrangement of the capsules, and the foreign body sensation on the supporting surface is eliminated by reducing the gap between adjacent capsules. The arc segment is provided to connect the linear segments, which plays a positioning role for the linear segments and ensures that the linear segments are arranged parallel to each other. The connecting piece is provided at the junction of the arc segment and the linear segment to ensure the continuity of the linear segment and the arc segment, and to avoid the tie rod, thereby preventing the weld formed by welding from overlapping and causing the risk of air leakage, thereby ensuring the reliability of the seal.

[0008] Preferably, the bladder is provided with horizontally arranged tie bars, and the bladder is divided into an upper cavity and a lower cavity that are interconnected. The width of the tie bars is smaller than the width of the bladder, so that the bladder is in the shape of a funnel with the middle part shrinking inward. The upper cavity and the lower cavity are formed by separation to limit the deformation of the bladder, thereby ensuring that the bladder maintains a preset contour. Tie bars are provided between the side walls of the bladder, and the tie bars have a pulling and limiting effect on the middle part of the side walls of the bladder, so that the bladder forms a funnel shape with the middle part shrinking inward after inflation, which not only ensures that the height of the bladder can be effectively increased after inflation, improves the sensitivity of the bladder hardness adjustment, and improves the effectiveness of support, but also effectively prevents the side walls of adjacent bladders from rubbing against each other, effectively eliminates the noise generated by the friction between adjacent bladders, and improves the user experience.

[0009] Preferably, the tie bars are in the form of elongated strips, with their side edges continuously bonded along the sidewalls of the linear segments to avoid the connecting tabs. Bonding along the length of the linear segments allows for effective pulling of all regions of the linear segments, ensuring parallelism between the segments, effectively maintaining the capsule contour, and facilitating assembly and use. The tie bar side edges are positioned along the linear segments to avoid contact with the connecting tabs, preventing multiple welding in the same area, which could affect sealing reliability.

[0010] Preferably, the tie rod is located at the midline of the sidewall of the linear segment, so that the upper and lower cavities have the same height. The tie rod is located in the middle of the bladder body, ensuring that the upper and lower cavities are symmetrically arranged around the tie rod, ensuring balanced reception and preventing tilting or offsetting of the bladder body.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] The beneficial effects of the present invention are as follows: the end face sheets are adhered to the upper and lower ends of the edge sheets and welded and adhered to form a capsule. The edge sheets are formed by adhering two substrates of the same length. This not only reduces the requirement for the length of the substrate by increasing the number of substrates, thereby facilitating the supply of raw materials and reducing costs, but also facilitates the batch preparation of raw materials by using substrates of the same length, thereby improving the user experience.

[0023] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0024] Example 1:

[0025] This embodiment provides a strip-shaped airbag with a spliced substrate.

[0026] like Figure 1 and 2 The illustrated strip-shaped airbag comprises an elongated airbag body 1, comprising an end sheet 3 and an annular edge sheet 4. The end sheet 3 covers the upper and lower ends of the edge sheet 4. The end sheet 3 and the edge sheet 4 are bonded together to form the airbag body 1. The edge sheet 4 is formed by bonding two elongated substrates 12 of the same length to shorten the length of the substrates 12. The end sheet 3 is bonded and welded to the upper and lower ends of the edge sheet 4 to form the airbag body 1. The edge sheet 4 is formed by bonding two substrates 12 of the same length. This not only reduces the length requirement of the substrates 12 by increasing the number of substrates 12, thereby facilitating the supply of raw materials and reducing costs, but also facilitates the batch preparation of raw materials by using substrates 12 of the same length, improving the user experience.

[0027] In this embodiment, the capsule 1 includes an end sheet 3, a base material 12, a connecting piece 13 and a tie rod 2. During installation, first, the base material 12 is spliced end to end to form a ring, and the corresponding end edges of adjacent base materials 12 are aligned and spliced and welded and bonded through the connecting piece 13 to form a surrounding sheet 4; then, the tie rod 2 is inserted into the surrounding sheet 4, and the side edges of the tie rod 2 are welded and bonded to the linear segment of the surrounding sheet 4 and avoid the connecting piece 13; finally, the end sheet 3 is covered on the upper and lower ports of the surrounding sheet 4 and bonded by welding.

[0028] After installation, the end sheet 3 and the base material 12 are welded to form a sealed bladder 1. The tie rod 2 is set in the bladder 1 and acts as a pull on the middle part of the bladder 1, ensuring that the bladder 1 is funnel-shaped with the middle part shrinking inward. It also acts as a limiter on the middle part of the bladder 1 to prevent the side walls of adjacent bladders 1 from rubbing against each other and causing noise. The edge sheet 4 is formed by welding two pieces of base material 12 of the same size together end to end. This can reduce the size requirements of a single base material 12 by providing multiple base materials 12, thereby reducing processing difficulty and improving processing efficiency. It can also facilitate batch processing by using base materials 12 of the same size, without affecting production efficiency due to the requirements of multiple sizes.

[0029] In this embodiment, the end sheet 3 and base material 12 are independently processed and welded together to form the bladder 1. This not only facilitates mass production of the end sheet 3 and base material 12, but also reduces the welding and bonding workload by limiting the number of components, thereby improving assembly efficiency. The edge sheet 4 is cylindrical and tubular, including vertically aligned upper and lower ports. The end sheet 3 is composed of two pieces, which cover the upper and lower ports of the edge sheet 4, respectively, to form the bladder 1, which is isolated from the outside world. This ensures that the air pressure within the bladder 1 can be adjusted and effectively maintained.

[0030] In this embodiment, the corresponding end edges of adjacent substrates 12 are flattened and bonded together via a connecting piece 13, so that the end edges of adjacent substrates 12 are sealed. The connecting piece 13 is in the form of an elongated strip, and its length matches the length of the end edges of the substrates 12, so that the connecting piece 13 completely blocks the gap between the corresponding end edges of adjacent substrates 12. The substrates 12 have the same width. During production, the corresponding end edges of the substrates 12 are aligned with each other and flattened. The connecting piece 13 is laid along the gap between the substrates 12, so that the two side edges of the connecting piece 13 overlap with the end edges of the substrates 12 on both sides. Continuous welding ensures that a sealed weld is formed between the connecting piece 13 and the corresponding end edges of the substrates 12, thereby ensuring that the adjacent substrates 12 are sealed and connected, ensuring the sealing of the capsule 1.

[0031] In actual operation, 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 connecting piece 13 is provided at the junction of the arc segment 6 and the linear segment 5 (e.g. Figure 4 The substrate 12 is a flat sheet, one end of which is bent to form an arc segment 6, and the remaining area forms a linear segment 5. When the substrates are bonded together to form the edge sheet 4, the linear segments 5 of adjacent substrates 12 are bonded to the arc segments 6, so that the edge sheet 4 has parallel linear segments 5 of equal length. The tie bars 2 are elongated sheets, and the side edges of the tie bars 2 are continuously bonded along the sidewalls of the linear segments 5 to avoid the connecting piece 13. This prevents repeated welding of parts of the edge sheet 4 from affecting the structural seal, ensuring a reliable overall seal of the bladder 1.

[0032] In this embodiment, the bladder 1 is provided with a horizontally arranged tie rod 2, and the bladder 1 is divided into an upper cavity 7 and a lower cavity 8 which are connected to each other (such as Figure 3 As shown), the width of the tie rod 2 is smaller than the width of the bladder 1, so that the bladder 1 is funnel-shaped with the middle part shrinking inward. The tie rod 2 is located at the midline of the side wall of the linear segment 5, so that the upper cavity 7 and the lower cavity 8 have the same height. The upper cavity 7 and the lower cavity 8 are connected by a channel provided at the end of the bladder 1, ensuring that the upper cavity 7 and the lower cavity 8 can share the air nozzle 9 and realize synchronous air pressure adjustment, ensuring that the bladder 1 can be raised and lowered vertically and reduce the tilt amplitude, providing vertical force for the user. The side edge of the tie rod 2 is continuously adhered to the midline of the linear segment 5 in the horizontal direction, so that the upper cavity 7 and the lower cavity 8 have the same height, ensuring that the upper cavity 7 and the lower cavity 8 have the same mechanical performance, thereby improving the deformation synchronization of the top and bottom of the bladder 1.

[0033] 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.

[0034] 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.

[0035] In this embodiment, the end surface of the capsule 1 is provided with an air nozzle 9 (such as Figure 5 As shown, the air nozzle 9 is independently machined and assembled on the bladder body 1, facilitating both processing and assembly. A mounting hole is provided at the bottom of the arc segment 6, through which the air nozzle 9 is welded and bonded. This ensures that the air nozzle 9 is securely attached to the bladder body 1 and communicates with the lower chamber 8, thereby enabling synchronous regulation of the air pressure within the upper and lower chambers 7 and 8. The air nozzle 9 is preferably located in the middle or bottom portion of the end face.

[0036] Example 2:

[0037] Compared with the first embodiment, this embodiment provides a mattress.

[0038] like Figure 6The 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.

[0039] In this embodiment, the support capsule 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 capsules 1 .

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.
