Technical Field
[0001] This utility model relates to the field of inflatable product technology, and more specifically, to a hollowed-out inflatable gas strap structure and inflatable gas. Background Technology
[0002] Inflatable products are a type of modern furniture primarily made of flexible materials such as PVC, nylon, or rubber. They are rapidly inflated with air using built-in valves and electric or manual air pumps, offering both portability and comfort. Common forms include inflatable beds, sofas, chairs, and beanbag chairs. Their key features include a lightweight structure, compressibility to a very small volume when stored (usually only a few kilograms), and suitability for various scenarios. Their advantages include easy assembly, space saving, convenient transportation and handling, simple cleaning and maintenance, and significantly lower cost compared to traditional solid wood or fabric furniture. Therefore, inflatable products are widely used in outdoor camping, picnics, beach leisure, and other mobile scenarios, providing flexible solutions for temporary accommodation or rest. They are also commonly found in homes, renters, or for expanding space in small apartments, solving the problem of fixed furniture taking up space. They can also be used as quick-assembly displays for guesthouses, exhibitions, and temporary events; even inflatable mattresses used in medical care to assist with bed rest fall into this category. With its core advantages of being lightweight and adaptable, inflatable furniture is becoming a preferred choice for balancing practicality and convenience in contemporary diverse lifestyles.
[0003] Inflatable products typically include built-in straps as auxiliary fixing components to enhance overall rigidity and stability, while preventing excessive expansion after inflation that could affect usability. However, the use of straps can also have negative impacts. First, it increases overall weight. Straps are mostly made of dense materials such as nylon and polyester. Even if each strap weighs only a few tens of grams, the extra straps make the originally lightweight inflatable furniture bulky, hindering long-distance transport or frequent movement, thus weakening its core advantage of "portability." Second, it affects breathability. Most straps are solid or densely woven. Having multiple straps or sheet-like straps inside an inflatable product can block local airflow, creating tiny enclosed areas. This not only affects inflation efficiency but also the overall airflow within the inflatable product, thereby reducing its comfort. Utility Model Content The present invention aims to overcome at least one defect (deficiency) of the prior art and provide a hollowed-out gas-filled pull strap structure and gas filling, thereby reducing the weight of the pull strap and improving portability.
[0004] One objective of this utility model is to provide a hollowed-out inflatable pull strip structure, including an end face and a side face. The end face is connected to the upper and lower ends of the side face. The side face is formed by a hollow strip. The end face includes an adhesive piece and a hollow strip extending from the side face to the end face. One side of the adhesive piece is attached to the hollow strip, and the other side is fused to the inner wall of the inflatable structure.
[0005] In this technical solution, the inflatable gas can be an inflatable bed, inflatable sofa, etc., and the end face of the inflatable pull strap structure is the side connected to the inflatable gas. The perforated strip can be a strip with a perforated pattern, a mesh strip, or a fiber strip, etc. The end face of the pull strap structure includes two layers: an adhesive piece and a perforated strip. The adhesive piece is attached to the outside of the perforated strip, that is, in the upper end face, the adhesive piece is attached to the upper side of the perforated strip, and in the lower end face, the adhesive piece is attached to the lower side of the perforated strip.
[0006] This design effectively reduces the weight of the pull strap structure by making its sides perforated. This is especially beneficial when there are many pull straps or a large side area, significantly reducing the weight the pull strap structure contributes to inflation and meeting the need for lightweight inflatable gases, making them easier to carry and store. Furthermore, the perforated side design allows for better airflow inside the inflatable gas, improving inflation efficiency and preventing confined spaces from affecting overall airflow, thus enhancing overall comfort during inflation.
[0007] After inflation, the pull strap structure is stretched, requiring a high degree of strength at the connection between the end face and the side. Compared to solid straps, perforated straps are relatively more difficult to connect and are prone to instability. In this solution, the perforated straps on the end face and the side face are connected as a single unit, which not only reduces the number of connection steps but also increases the connection strength between the side face and the end face, extending the service life of the pull strap structure.
[0008] In addition, if the sides and cross-sections are connected by solid materials, the deformation capacity is poor and they are easily torn under stress. This solution sets the sides and ends as hollow strips for connection, which has a strong deformation capacity and can adapt to the stretching during inflation and use, thus improving durability.
[0009] Compared to solid strips, the open areas of perforated strips increase the difficulty of connecting them to other structures. If the perforated strip at the end face is directly connected to the inflated gas, the volume of the gas will increase the difficulty of connecting the perforated strip. This solution uses a bonding plate at the end face of the pull strip structure to reduce the difficulty of connecting the end face to the inflated gas, improving production efficiency. Furthermore, the bonding plate fills the open areas of the perforated strip at the end face, improving the connection strength between the end face and the inflated gas and preventing cracks from appearing in the stress-concentrated areas of the end face after inflation.
[0010] Furthermore, it includes a side surface, wherein the end face is connected to the upper and lower ends of the side surface to form a sheet-like pull strip structure; or, it includes at least two side surfaces, wherein the side surfaces are disposed on opposite sides of the end face, and an open structure is formed between adjacent two side surfaces along the edge of the end face. Furthermore, the gas-inflatable pull strip structure is formed by connecting and surrounding the ends of a perforated strip with two bonding pieces, the bonding pieces being disposed on the outside of the perforated strip to form the end face.
[0011] Furthermore, the gas-inflatable belt structure is formed by connecting and enclosing the ends of two hollowed-out belts with adhesive tabs, the adhesive tabs being disposed on the outer side of the hollowed-out belts to form the end face.
[0012] Furthermore, the gas-inflatable pull strip structure is a hollow strip with adhesive pieces connected to both ends, and the adhesive pieces are located on the outside of the hollow strip to form the end face.
[0013] Furthermore, the ends of the perforated strip are connected by sewing, hot melting and / or adhesive.
[0014] Furthermore, the hollow strip is formed by cutting a hollow sheet, and the hollow sheet is configured to have an adhesive strip connected at a designated position, so that a hollow strip with an adhesive strip is formed after cutting.
[0015] Furthermore, the perforated strip is made of fiber cloth or mesh cloth, and the bonding sheet is made of PVC sheet or TPU sheet; the bonding sheet and the perforated strip are connected by adhesive and / or hot melt bonding.
[0016] Another objective of this utility model is to provide an inflatable body comprising a top surface, a bottom surface, and a surrounding band, and further comprising a perforated inflatable pull band structure as described above. The pull band has an upper end surface and a lower end surface. The upper side of the adhesive piece on the upper end surface is connected to the top surface, and the lower side of the adhesive piece on the lower end surface is connected to the bottom surface; and / or, the upper side of the adhesive piece on the upper end surface is connected to the top surface, the lower side of the adhesive piece on the lower end surface is connected to the surrounding band, the lower side of the adhesive piece on the lower end surface is connected to the bottom surface, and the upper side of the adhesive piece on the upper end surface is connected to the surrounding band.
[0017] Furthermore, the bonding sheet located on the end face is fused to the top and bottom surfaces to form a fusion zone; or, the bonding sheet located on the end face is fused to the top or bottom surface and the surrounding strip to form a fusion zone.
[0018] In this technical solution, the bonding piece located on the end face is fused to the top or bottom face and the surrounding strip. This can be understood as the bonding piece on the end face being fused to the top face and the surrounding strip, or the bonding piece on the end face being fused to the bottom face and the surrounding strip.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention effectively reduces the weight of the pull strap structure by designing its sides as perforated strips. This is especially beneficial when there are many pull straps or a large side area, significantly reducing the weight the pull strap structure contributes to inflation, meeting the need for lightweight inflation, and making it easier to carry and store. Furthermore, the perforated side design allows for better airflow inside the inflation system, improving inflation efficiency and preventing enclosed spaces from affecting overall breathability, thus enhancing overall comfort.

Detailed Implementation
[0041] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0042] Example 1 refer to Figure 1 In conjunction with other accompanying drawings, this embodiment provides a perforated gas-filled pull strap structure, including an end face 100 and a side face 200. The end face 100 is connected to the upper and lower ends of the side face 200. The side face 200 is formed by a perforated strip 300. The end face 100 includes an adhesive piece 400 and a perforated strip 300 extending from the side face 200 to the end face 100. One side of the adhesive piece 400 is attached to the perforated strip 300, and the other side is fused to the inner wall of the gas-filled 500.
[0043] In this technical solution, the air inflator 500 can be an inflatable bed, inflatable sofa, etc., and the end face 100 of the air inflatable pull strap structure is the side connected to the air inflator 500. The perforated strip 300 can be a strip with a perforated pattern, a mesh strip, or a fiber strip, etc. The end face 100 of the pull strap structure includes a two-layer structure, namely, an adhesive piece 400 and a perforated strip 300. The adhesive piece 400 is attached to the outside of the perforated strip 300, that is, in the upper end face 100, the adhesive piece 400 is attached to the upper side of the perforated strip 300, and in the lower end face 100, the adhesive piece 400 is attached to the lower side of the perforated strip 300.
[0044] This design effectively reduces the weight of the pull strap structure by making the side 200 of the pull strap structure a hollowed-out strip 300. This is especially beneficial when there are many pull straps or the side 200 area is large, significantly reducing the weight the pull strap structure adds to the inflator 500, meeting the need for lightweight design and facilitating carrying and storage. Furthermore, the hollowed-out design of the side 200 allows for better airflow inside the inflator 500, improving inflation efficiency and preventing confined spaces from affecting overall airflow, thus enhancing the overall comfort of the inflator 500.
[0045] After inflation to 500g, the strap structure is stretched, requiring a high degree of stability at the connection between end face 100 and side face 200. Compared to solid straps, the perforated strap 300 is more difficult to connect and is prone to instability. In this design, the perforated strap 300 at end face 100 and the perforated strap 300 at side face 200 are integrated, which not only reduces the number of connection steps but also increases the connection strength between side face 200 and end face 100, extending the service life of the strap structure.
[0046] Compared to a solid strip, the perforated area of the perforated strip 300 increases its connection to other structures. If the perforated strip 300 on the end face 100 is directly connected to the inflatable gas 500, the volume of the inflatable gas 500 will increase the difficulty of connecting the perforated strip 300. In this solution, the end face 100 of the pull strip structure is equipped with a bonding piece 400, which reduces the difficulty of connecting the end face 100 and the inflatable gas 500, improves production efficiency, and fills the perforated area of the perforated strip 300 on the end face 100, improving the connection strength between the end face 100 and the inflatable gas 500 and preventing cracks from appearing in the area of the end face 100 where the stress is concentrated after inflation.
[0047] For example, the inflatable pull strap structure of this embodiment includes a side surface 200, and the end face 100 is connected to the upper end and the lower end of the side surface 200 to form a sheet-like pull strap structure; the inflatable pull strap structure is a hollow strip 300 with adhesive pieces 400 connected to both ends, and the adhesive pieces 400 are disposed on the outside of the hollow strip 300 to form the end face 100.
[0048] In this technical solution, the side surface 200 of the pull strap structure is sheet-like. Compared to a tubular pull strap, the sheet-like pull strap structure is beneficial for increasing the contact area between the end face 100 and the gas filling 500, thereby improving the connection's firmness. Preferably, the side surface 200 is connected to the same side of the upper end face 100 and the lower end face 100. Specifically, the end face 100 is rectangular, and the perforated strip 300 of the side surface 200 is connected to the long side of the end face 100.
[0049] The bonding piece 400 is located on the outer side of the perforated strip 300, so that when the end face 100 is formed, the bonding piece 400 is on the side of the end face perforated strip 300 close to the gas filling 500, facilitating the connection of the end face 100 perforated strip 300 to the gas filling 500 via the bonding piece 400. This design only requires bonding the bonding piece 400 to the perforated strip 300 and then welding the bonding piece 400 to the gas filling 500, simplifying the manufacturing process and greatly improving production efficiency.
[0050] Further, refer to Figure 2 The perforated strip 300 is formed by cutting a perforated piece 320, and then attaching an adhesive piece 400 is applied to it so that after the ends of the perforated strip 300 are connected, the adhesive piece 400 is located on the outer side of the perforated strip 300 to form an end face. Alternatively, refer to... Figure 5 and Figure 6 The hollow strip 300 is formed by cutting a hollow piece 320. The hollow piece 320 is configured to have an adhesive strip 330 connected at a designated position, so that after cutting, a hollow strip 300 with an adhesive piece 400 is formed.
[0051] In this technical solution, specifically, the perforated piece 320 is rectangular in shape. Adhesive strips 330 are glued to both ends of the perforated piece 320, with the edges of the adhesive strips 330 coinciding with the edges of the perforated piece 320. The piece is then cut to form a pull strip structure. The process is simple and highly efficient. Furthermore, the perforated strips 300 cut from a single perforated piece 320 have consistent thickness and other structural characteristics, preventing uneven stress on the inflator 500 due to variations in the quality of the perforated strips 300, thus improving the product quality of the inflator 500.
[0052] In this embodiment, the perforated strip 300 is a fiber cloth or a mesh cloth, and the bonding sheet 400 is a PVC sheet or a TPU sheet; the bonding sheet 400 and the perforated strip 300 are connected by adhesive bonding, or the bonding sheet 400 and the perforated strip 300 are connected by heat fusion, or the bonding sheet 400 and the perforated strip 300 are connected by adhesive bonding and heat fusion bonding.
[0053] Example 2 refer to Figures 2 to 8 This embodiment provides a hollowed-out inflatable pull strap structure, including an end face 100 and a side face 200. The end face 100 is connected to the upper and lower ends of the side face 200. The side face 200 is formed by a hollowed-out strip 300. The end face 100 includes an adhesive piece 400 and a hollowed-out strip 300 extending from the side face 200 to the end face 100. One side of the adhesive piece 400 is attached to the hollowed-out strip 300, and the other side is fused to the inner wall of the inflatable 500.
[0054] For example, the gas-inflatable pull strap structure of this embodiment includes at least two sides 200, which are disposed on opposite sides of the end face 100, and an open structure is formed between two adjacent sides 200 along the edge of the end face 100.
[0055] In this technical solution, the pull strap structure may include two, three, or four sides 200, etc. An open structure between adjacent sides 200 constitutes a structure without sides 200. For example, the end face 100 is rectangular, with a side 200 on one opposite side and a through-type side without a side 200 on the other opposite side.
[0056] The design of at least two sides 200 ensures that the pull straps limit the expansion of the gas 500 and maintain its stiffness. The open structure further reduces the weight of the gas 500, which helps to enhance the airflow inside the gas 500, improve inflation efficiency, and enhance the overall flow of the gas 500.
[0057] Furthermore, the gas-inflatable belt structure is formed by connecting and surrounding the ends of a perforated belt 300 with two bonding pieces 400, and the bonding pieces 400 are disposed on the outside of the perforated belt 300 to form the end face 100.
[0058] The ends of the perforated strip 300 are connected by sewing, hot melting and / or adhesive.
[0059] In this technical solution, the bonding piece 400 is positioned at the end face 100 after the hollow strip 300 is connected end to end at the bonding position of the bonding piece 400.
[0060] The perforated strip 300 is formed by connecting the two ends, which is simple in process, highly efficient in production, and eliminates many splicing points. This avoids localized weaknesses caused by material differences and seam wear, improving the overall tensile strength of the pull strip and making its performance more stable. In addition, since the end face 100 is a stress-concentrated area, this design places the seam on the side 200, which helps maintain the integrity and flatness of the end face 100 material and improves the tear resistance of the pull strip.
[0061] In this embodiment, the two ends of the hollow strip 300 are sewn together to form a seam line 210, and it is a butt stitch. Specifically, the two ends of the hollow strip 300 are folded outward or inward and then sewn together.
[0062] Furthermore, the perforated strip 300 is formed by cutting a perforated sheet 320, which is configured to have an adhesive strip 330 connected at a designated position, so that after cutting, a perforated strip 300 with an adhesive strip 400 is formed. The adhesive strip 330 is attached to the perforated sheet 320 by adhesive or heat fusion.
[0063] Specifically, when the strap structure in this embodiment is applied to an air bed, the hollow sheet 320 can be cut into a short-sided hollow strip 300, so that after the hollow strip 300 is connected end to end to form a strap, the longitudinal side length is greater than the transverse side length in the direction of the length of the gas 500; or the hollow sheet 320 can be cut into a long-sided hollow strip 300, so that after the hollow strip 300 is connected end to end to form a strap, the transverse side length in the direction of the length of the gas 500 is greater than the longitudinal side length.
[0064] In this embodiment, the perforated strip 300 is a fiber cloth or a mesh cloth, and the bonding sheet 400 is a PVC sheet or a TPU sheet; the bonding sheet 400 and the perforated strip 300 are connected by adhesive bonding, or the bonding sheet 400 and the perforated strip 300 are connected by heat fusion, or the bonding sheet 400 and the perforated strip 300 are connected by adhesive bonding and heat fusion bonding.
[0065] When the gas-filled tufted structure includes only one side 200, the welding area 610 is a linear welding area 610.
[0066] When the gas-filled pull strip structure includes at least two sides 200, the welding area 610 is a circular welding area 610 or a U-shaped welding area 610.
[0067] Example 3 refer to Figure 9 and Figure 10 This embodiment provides a perforated inflatable pull strap structure, similar to that of Embodiment 2, except that: the inflatable pull strap structure is formed by connecting and surrounding the ends of two perforated strips 300 with adhesive pieces 400, and the adhesive pieces 400 are disposed on the outer side of the perforated strips 300 to form the end face 100. The ends of the perforated strips 300 are connected to the side 200 of the pull strap by sewing, hot melting and / or adhesive.
[0068] Example 4 refer to Figure 11 This embodiment provides a hollowed-out inflatable pull strap structure, which is similar to the structure of Embodiment 2, except that: The ends of the perforated strip 300 are connected by folding and sewing. Specifically, the first and last ends of the perforated strip 300 are folded horizontally outward or inward once, and then folded vertically upward or downward a second time. The first fold is sewn together, and the second fold is sewn together with the folded perforated strip 300. This improves the strength of the sewn connection and enhances the performance stability of the pull strap.
[0069] Example 5 refer to Figure 12 This embodiment provides a hollowed-out inflatable pull strap structure, which is similar to the structure of Embodiment 2, except that: The ends of the perforated strip 300 are connected by a flat overlapping stitch. Specifically, the ends of the perforated strip 300 partially overlap in the longitudinal direction, and the overlapping parts are stitched together.
[0070] Example 6 This embodiment provides a hollowed-out inflatable pull strap structure, which is similar to the structure of Embodiment 2, except that: refer to Figure 13 The ends of the perforated strip 300 are joined by butt joints and then edge-sealed and sewn together. Specifically, the ends of the perforated strip 300 are folded outwards or inwards, sewn together at the fold, and then wrapped with an edge-sealing fabric 310 and sewn again.
[0071] Example 7 refer to Figures 14 to 17 This embodiment provides an inflatable 500, including an inflatable body formed by a top surface 610, a bottom surface 700, and a surrounding strap 800. It also includes an inflatable pull strap structure provided in any one of embodiments 1 to 6. The inflatable pull strap structure is a middle pull strap 910. The end face 100 of the inflatable 500 pull strap includes an upper end face 100 and a lower end face 100. The upper side of the bonding piece 400 of the upper end face 100 is welded to the top surface 610 to form a welded area 610 of the top surface 610. The lower side of the bonding piece 400 of the lower end face 100 is welded to the bottom surface 700 to form a welded area 610 of the bottom surface 700.
[0072] The bonding sheet 400 is fused to the top surface 610 and the bottom surface 700 to form a fusion area 610. Preferably, when the bonding sheet 400 is fused to the top surface 610 or the bottom surface 700, the perforated strip 300 of the end face 100 is also fused together, which further strengthens the connection between the gas filling 500, the bonding sheet 400 and the perforated strip 300, and improves the tensile strength.
