Description

Technical Field

[0001] The utility model relates to the field of inflatable facilities, in particular to an inflatable body structure. Background Art

[0002] Inflatable structures are made of materials that can contain air cavities that are inflated, where the air is used as an element to support and stabilize the structure. Inflatable structures have many advantages, including lightness, ease of carrying, quick installation, and good flexibility. They are widely used in various fields, such as floats (such as lifebuoys, lifeboats, kayaks), temporary shelters (such as inflatable tents, inflatable buildings, etc.), packaging (cushion bags), inflatable toys, shoes, clothing, etc.

[0003] If the existing inflatable structure wants to present a predetermined shape in the inflated state, please refer to the inflatable boat structure with the authorization announcement number CN201082757Y for details. First, multiple air cavities are spliced ​​to form, and the specific predetermined shape and height after inflation need to be adjusted according to the shape and position of the spliced ​​air cavities, which has poor integrity and complicated installation; second, the entire air cavity is formed by hot pressing or bonding the upper and lower surfaces of some areas, and the specific predetermined shape and height after inflation need to be adjusted according to the bonding area and position. Although it has good integrity and simple installation, it cannot achieve the predetermined shape without any bonding and all parts are inflated. The shape can be a design effect with ups and downs and an overall concave and convex feeling. Utility Model Content

[0004] To this end, it is necessary to provide an inflatable body structure that can assume a predetermined shape in the inflated state without any bonding of the inflatable portion.

[0005] To achieve the above-mentioned purpose, the utility model provides an inflatable structure, which includes an air cavity, wherein the air cavity includes an upper surface and a lower surface, and the air cavity has a plurality of connecting lines connecting the upper surface and the lower surface. The heights of the plurality of connecting lines in the height direction are determined so that the air cavity presents a predetermined shape when inflated.

[0006] Furthermore, the plurality of connecting lines are in a Z shape or a cross shape.

[0007] Furthermore, the plurality of connecting lines are formed by interweaving a yarn on the upper surface and the lower surface.

[0008] Furthermore, the plurality of connecting lines are formed by interweaving two yarns on the upper surface and the lower surface.

[0009] Furthermore, the upper surface and the lower surface respectively include a base fabric layer and a sealing material layer which are stacked and connected, or a composite layer of a composite material having a sealing material layer.

[0010] Furthermore, a plurality of connecting lines connect the upper surface and the lower surface without passing through the outermost sealing material layer.

[0011] Furthermore, the upper surface and the lower surface respectively include a base fabric layer and a sealing material layer connected in layers or a composite layer of a composite material having a sealing material layer;

[0012] The yarn connects the upper surface and the lower surface, does not pass through the outermost layer, and has several sections of bonding lines.

[0013] Furthermore, the yarn connects the upper surface and the lower surface, does not pass through the outermost sealing material layer, and has a plurality of sections of bonding lines.

[0014] Different from the prior art, the above technical solution connects the upper and lower surfaces of the air cavity through several connecting lines, and flexibly controls the shape of the air cavity by setting several connecting lines in the height direction; after the air cavity is inflated, the pressure inside the air cavity increases, and several connecting lines form straight lines due to the pressure inside the cavity, so that the connecting lines and the upper and lower surfaces of the air cavity form a support structure, which maintains the shape and stability of the air cavity and prevents the air cavity from deforming or collapsing. The height of the connecting lines in the height direction can flexibly control the height of each part of the air cavity, so that the air cavity presents a pre-designed shape. When it needs to be folded and stored, the air cavity is deflated, and the connecting lines naturally fall down, making the air cavity plastic, which is convenient for folding and carrying.

[0039] See also Figure 1-Figure 4As shown, the utility model provides an inflatable gas structure, including an air cavity 40, the upper surface 10 and the lower surface 20 of the air cavity 40 are connected by a plurality of connecting lines 301, and the shape of the air cavity 40 can be flexibly controlled by setting the height of the plurality of connecting lines 301 in the height direction; in the application, an inflation hole is usually left in the air cavity for gas to enter, and after the gas is inflated from the inflation hole, the pressure in the air cavity 40 increases, and the plurality of connecting lines 301 form a straight line due to the pressure in the cavity, so that the connecting line 301 and the upper surface 10 and the lower surface 20 of the air cavity 40 form a support structure, which maintains the shape and stability of the air cavity 40 and can prevent the air cavity 40 from being deformed or collapsed. The height of the connecting line 301 in the height direction can flexibly control the height of each part of the air cavity 40, so that the air cavity 40 presents a pre-designed shape, and when it needs to be folded and stored, the air cavity 40 is deflated, and the connecting line 301 naturally hangs down, so that the air cavity 40 becomes plastic, which is convenient for folding and carrying.

[0040] The above-mentioned inflatable structure can be represented by any inflatable product and / or article that is deemed feasible and / or appropriate, such as floating objects (such as life jackets, lifebuoys, lifeboats, kayaks), temporary shelters (such as inflatable tents, inflatable buildings, etc.), packaging (such as cushioning bags), inflatable toys, shoes (uppers, insoles, etc.), clothing, decorations, etc.

[0041] The following is a detailed description of an inflatable structure provided by the utility model. An inflatable structure includes an air cavity 40, the air cavity 40 includes an upper surface 10 and a lower surface 20, and the air cavity 40 has a plurality of connecting lines 301 connecting the upper surface 10 and the lower surface 20, and the heights of the plurality of connecting lines 301 in the height direction are determined so that the air cavity 40 presents a predetermined shape in the inflated state.

[0042] The upper and lower in the upper surface 10 and the lower surface 20 are only used to indicate the orientation. The air cavity 40 can be formed by the same surface and completely without splicing, or it can be formed by splicing multiple surfaces. The splicing can be formed by splicing all or part of the same surface, or it can be formed by splicing completely different surfaces. Different surfaces refer to surfaces with different materials, synthetic materials, shapes, sizes, thicknesses, etc. The height of the above-mentioned several connecting lines 301 in the height direction refers to the height of the projection of the upper surface 10 and the lower surface 20 of the air cavity 40 connected by the several connecting lines 301 in the height direction.

[0043] See also Figure 1 and Figure 2As shown, the upper surface 10 and the lower surface 20 of the above-mentioned several sections of connecting lines 301 can be in a straight line, a Z-shaped, an oblique line, a cross shape, etc., preferably in a Z-shaped or cross shape. The Z-shaped or cross shape can increase the intersection points between the connecting lines 301, and the connecting lines 301 cross or intersect in different directions, which can more evenly disperse the pressure inside the air cavity 40. It helps to avoid excessive accumulation of gas in certain areas, more evenly disperse the pressure inside the air cavity 40, reduce the possibility of structural deformation, and effectively disperse and absorb stress when subjected to external force or pressure, provide better structural support, and achieve good effects such as uniform pressure distribution and improved anti-deformation ability.

[0044] In some embodiments, the plurality of connecting lines 301 may be formed by interweaving one yarn 30 on the upper surface 10 and the lower surface 20. In some embodiments, the plurality of connecting lines 301 may be formed by interweaving two yarns 30 on the upper surface 10 and the lower surface 20. The one or two yarns 30 mentioned above refer to the plurality of connecting lines 301 formed by interweaving on the upper surface 10 and the lower surface 20 within the range of the length limit of the yarn 30. The interweaving of one or two yarns 30 between the upper surface 10 and the lower surface 20 can reduce the deformation and change of the connecting line 301 during tension or compression. The connecting line 301 can withstand greater tension and pressure and has better tensile strength, making the connecting line 301 more stable and less likely to loosen or deform. At the same time, there is no need to sew or tie each of the several sections of connecting line 301 between the upper surface 10 and the lower surface 20. Only one or two yarns 30 need to be sewed or tied between the upper surface 10 and the lower surface 20, which reduces the connection process and improves production efficiency.

[0045] The upper surface 10 and the lower surface 20 can have any thickness deemed appropriate, for example, considering the expected inflatable structure, such as a range from a few tenths of a millimeter to several millimeters. The upper surface 10 and the lower surface 20 can have shapes and sizes deemed appropriate, and can be adaptively selected according to the expected inflatable structure. The materials, synthetic materials, shapes, sizes, thicknesses, etc. of the upper surface 10 and the lower surface 20 are different. The upper surface 10 and the lower surface 20 can each be made of any known material (such as a mixture of one or more of polyester fibers, polyamide fibers, polypropylene fibers, TPU, etc.). The upper surface 10 and the lower surface 20 can also each be represented by a corresponding group of several layers stacked. As described, the upper surface 10 and the lower surface 20 each include but are not limited to a laminated base fabric layer and a sealing material layer or a composite layer of a composite material having a sealing material layer. That is, in some embodiments, the upper surface 10 and the lower surface 20 each include but are not limited to a laminated base fabric layer and a sealing material layer; in some embodiments, the upper surface 10 and the lower surface 20 each include but are not limited to a laminated base fabric layer and a composite material layer having a sealing material layer. The base fabric layer mentioned above can be a mesh, a flat cloth, etc. formed of any known material. The above-mentioned sealing material layer mainly serves to wrap and seal the gas-filled cavity to form a complete structure, effectively keep the gas inside the structure, and prevent leakage and gas loss. The base fabric layer can be coated with PVC, coated with TPU, or laminated with polyester fiber, polyamide fiber, polypropylene fiber, etc. The base fabric layer can also be coated with PVC, coated with TPU and / or laminated with polyester fiber, polyamide fiber, polypropylene fiber, etc. on the base fabric layer, and the base fabric layer can be completely the same, partially the same, or different.

[0046] See also Figure 3 and Figure 4As shown, the upper surface 10 and the lower surface 20 each include but are not limited to a laminated base fabric layer and a sealing material layer. That is, the upper surface 10 includes but is not limited to a laminated base fabric layer 101 and a laminated sealing material layer 102; the lower surface 20 includes but is not limited to a laminated base fabric layer 201 and a laminated sealing material layer 202; other layers can be added between and / or before and after the base fabric layer and the sealing material layer of the upper surface 10 and / or the lower surface 20 to form a material composite layer to increase the wear resistance, protective performance, air tightness, etc. of the inflatable structure to ensure the stability and safety of the structure, wherein the other layers can be the same and / or different from the base fabric layer and the sealing material layer. For example, the upper surface 10 and / or the lower surface 20 is a mesh layer, a hot melt adhesive layer, a sealing material layer, and a mesh layer laminated once. The connecting line 301 can pass through one, several, or all layers in the corresponding group of layers. Preferably, when the connecting line 301 connects the upper surface 10 and the lower surface 20, it does not pass through the outermost sealing material layer (the sealing material layer closest to the external air) to prevent gaps in the connection, which may cause air leakage, protect the airtightness of the inflatable body, and enhance the overall stability and durability of the structure.

[0047] See also Figure 4As shown, when one or two yarns 30 are interwoven between the upper surface 10 and the lower surface 20, the yarn 30 connects the upper surface 10 and the lower surface 20, does not pass through the outermost layer, and has several sections of bonding lines 302. That is, when the yarn 30 does not pass through the outermost layer (the layer closest to the external air), a part of the yarn 30 is bonded between the stacked layers to form bonding lines 302. The bonding lines 302 form a durable bonding line 302 between the stacked layers, increasing the contact area between the yarn 30 and the stacked layers. At the same time, during the process of compounding the stacked layers, the bonding line 302 can be fixed to prevent the bonding line 302 from moving, that is, to prevent the yarn 30 from sliding and detaching from the upper surface 10 and / or the lower surface 20, so that the height of the connecting line 301 in the height direction can be maintained, thereby maintaining the distance between the upper surface 10 and the lower surface 20, keeping the shape of the air cavity 40 stable, and ensuring the stability and integrity of the entire structure. Preferably, the yarn 30 connects the upper surface 10 and the lower surface 20, does not pass through the outermost sealing material layer, and has several sections of bonding lines 302. That is, when the yarn 30 does not pass through the outermost sealing material layer (the sealing material layer closest to the external air), a part of the yarn 30 is bonded between the stacked layers to form bonding lines 302. This can prevent the connection from generating gaps, which will cause air leakage, protect the airtightness of the inflatable body, and enhance the overall stability and durability of the structure; at the same time, it prevents the relative sliding and separation of the yarn 30 on the upper surface 10 and / or the lower surface 20, so that the height of the connecting line 301 in the height direction can be maintained, thereby maintaining the distance between the upper surface 10 and the lower surface 20, so that the shape of the air cavity 40 remains stable, and the stability and integrity of the entire structure are ensured.

[0048] The above-mentioned connecting line 301 can be represented by strands and / or threads of fibers such as polyester materials, cotton, polyester, nylon, etc., or can be represented by strands and / or threads of a plurality of different materials. The specific material of the thread or the types of yarns used to form the thread can be set according to the needs of the inflatable products and / or products of the specific application of the inflatable structure, providing more diverse functions and performances.

[0049] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described herein, or equivalent structural or equivalent process transformations made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the scope of patent protection of the utility model.
