Description

Aerated product

Technical Field

The present application relates to inflatable products. In particular, the present application relates to an inflatable product comprising a tensioning member.

Background

As material technology has evolved and social demands have increased, various portable devices have been increasingly used for applications in various different locations, for example, devices have moved from indoor use to outdoor use. As a representative, inflatable products are lightweight and easy to package and store, and have been widely used in life.

Most inflated products are formed into their predetermined shape by the setting of the internal structure, so that after inflation of the product, the product is brought to a predetermined final shape by the internal air pressure. For example, the inflation chamber of the inflatable product may be provided with a tensioning structure that is connected to the interior wall location of the inflation chamber so as to assume a desired shape after the inflatable product is pressurized.

With the increasing variety of inflatable products, some inflatable products need to have a higher air pressure in the inflatable chamber, so that the inflatable products can meet the use requirement. The connection of the tensioning member to the inner wall of the inflation chamber should therefore be very reliable, as should the tensioning member itself.

In the prior art, the inflatable product is often formed by splicing various sheet materials through high-frequency welding, so that the surface material and the inner tensioning member material of the product are often sheet elastic chemical materials capable of being welded at high frequency. PVC materials have been used as a widely used chemical material in most inflatable products. However, under the condition of higher internal air pressure of the product, due to the creep property (creep behavior) of the material, when the sheet-shaped internal tension member made of the PVC material bears higher tensile force (especially when the ambient temperature is higher), the sheet-shaped internal tension member can deform, so that the appearance of the inflatable product deforms, and the use of a user is influenced.

In the prior art, technicians sometimes use laminated construction materials as the internal tension members, for example, a layer of fabric is disposed between two layers of PVC film, and the laminate is made by a lamination process, such that creep characteristics of the internal tension members made of the laminate are changed, and the product deformation resistance is improved. However, this process material still undergoes some deformation and requires more PVC material, resulting in increased material costs; and after the product is abandoned, the PVC material is difficult to degrade, and the natural environment is negatively affected.

The skilled person would like to make the inner tension member of a material with high stretch resistant properties, such as cotton, chemical fabrics or fabrics of other materials. However, these fabrics cannot be fixed to the aforementioned sheet-like elastic chemical materials which can be welded at high frequencies, and therefore cannot be used.

Those skilled in the art have focused on developing an inflatable product technology to improve the stretch resistance of the internal tension members of the inflatable product, reduce the use of non-degradable materials, improve the natural environment, and reduce costs.

In the description of the present application, the meaning of "a plurality" is two or more unless explicitly defined otherwise.

In the description of the present application, an "inflated product" comprises at least one inflated chamber for inflation, in which the inflated product is in an inflated (inflated) state and maintains a certain shape after the pressure of the gas (e.g., air) within the inflated chamber reaches a desired value; after the gas in the inflation chamber of the inflation product is discharged, the inflation product is in a deflated state, and the volume of the inflation product is greatly reduced relative to the inflation product in the inflated state, so that the inflation product is convenient to store.

One or several tensioning members are provided in the inflation chamber of the inflatable product, at least two ends of the tensioning members being connected to the wall of the inflation chamber, respectively. The tensioning members, when tensioned, provide a pulling force to limit deformation of the walls of the inflation chamber so that the inflated product retains a certain shape after being inflated.

Referring to fig. 1, in an exemplary embodiment of the present application, the aerated product is an aerated water tank 1. The aerated water tank 1 comprises a tank wall 11 and a tank bottom 12. The tank wall 11 is connected to the tank bottom 12 and defines a water containing chamber 10. The cell wall 11 includes an inner wall 111, an outer wall 112, and an inflation chamber 115, the inflation chamber 115 being defined between the inner wall 111 and the outer wall 112. For example, the tank wall 11 further includes a top wall 113 and a bottom wall 114, wherein the top wall 113 is connected to the upper end of the inner wall 111 and the upper end of the outer wall 112, respectively, and the bottom wall 114 is connected to the lower end of the inner wall 111 and the lower end of the outer wall 112, respectively, and the inner wall 111, the outer wall 112, the top wall 113, and the bottom wall 114 define an inflation chamber 115. Ambient air enters the plenum 115 through a gas inlet (not shown) provided in the cell wall 11 so that the plenum 115 is inflated. Within the plenum 115 are disposed a plurality of tensioning members 14, one end of the tensioning members 14 being connected to the inner wall 111 and the other end of the tensioning members 14 being connected to the outer wall 112. The inner wall 111 and the outer wall 112 are pulled by the tensioning members 14 in the direction of the plenum 115, respectively, so that the tank wall 11 and the plenum 115 maintain the desired shape.

Each of the tension members 14 of the pneumatic pool 1 of fig. 1 is disposed vertically or substantially vertically within the pneumatic chamber 115, with the tension members 14 being arranged in an array within the pneumatic chamber 115. It will be appreciated that the tension members 14 arranged in a vertical direction or substantially in a vertical direction are merely illustrative of specific embodiments of the present application. For example, the tension member 14 in another embodiment is at an acute angle (e.g., without limitation, an acute angle of approximately 5 degrees, approximately 10 degrees, approximately 15 degrees, approximately 20 degrees, approximately 25 degrees, approximately 30 degrees, approximately 35 degrees, approximately 40 degrees, approximately 45 degrees, approximately 50 degrees, approximately 55 degrees, approximately 60 degrees, approximately 65 degrees, approximately 70 degrees, approximately 75 degrees, approximately 80 degrees, or approximately 85 degrees) with the horizontal. In another embodiment, the tension members 14 are arranged in a horizontal direction or disposed in a substantially horizontal direction. These embodiments are identical or substantially identical to embodiments in which the tension members 14 are arranged in a vertical direction or substantially in a vertical direction, except for the difference in the angle between the tension members 14 and the horizontal plane.

Fig. 2a shows a schematic structure in which the tension member 14 is connected to the inner wall 111 by a connecting member 13 in one embodiment. In this embodiment, the tension member 14 is connected to the inner wall 111 by the connecting member 13. For example, the tension member 14 is connected with the connection member 13, and the connection member 13 is connected with the inner wall 111, so that the tension member 14 is indirectly connected with the inner wall 111 through the connection member 13. It will be appreciated that the manner in which the tension member 14 is connected to the outer wall 112 is the same as the manner in which the tension member 14 is connected to the inner wall 111.

In this embodiment, as shown in fig. 2a, the connection member 13 is elongated and extends substantially linearly along the length direction thereof. In other embodiments, the connecting member 13 has other shapes, for example, referring to fig. 2b, the connecting member 13 is also elongated and extends in a curved manner along its length. In other embodiments, the connecting member 13 may take other shapes, such as a dog bone, a donut, an oval, a "C" shape, etc. of the connecting member 13, and the cross-section of the tensioning member 14 to which the connecting member 13 is connected may be correspondingly generally dog bone, donut, oval, C "shape, etc. Those skilled in the art will appreciate that these shapes of the connecting members 13 are not exhaustive examples and that connecting members 13 having the appropriate shape may be selected according to actual needs.

Referring to fig. 2a and 2b, in some embodiments, the tensioning member 14 is connected with the connecting member 13 by sewing. The tensioning member 14 and the connecting member 13 are connected to each other by one or more stitches, which in this embodiment form two rows of stitches 15 on the surface of the tensioning member 14. It will be appreciated that the number of stitches 15 formed by the suture on the surface of the tensioning member 14 need not be two, but may be more or less and that embodiments are within the scope of the present application. For example, referring to fig. 2c, the suture forms a row of stitches 15' on the surface of the tensioning member 14.

For convenience of explanation, the connection member 13 and the tension member 14 are described in detail below based on the connection member 13 shown in fig. 2a, and the connection manner of the connection member 13 and the inner and outer walls 111 and 112 is described in detail taking an end of the tension member 14 near the inner wall 111 as an example.

Connecting component

For convenience of description, only fig. 3a is used as an example. The connecting member is constituted by at least one strip-shaped structural unit 130. The tie bar structure unit 130 is composed of at least two materials to firmly bond the connecting member 13 and the tension member 14. Specifically, the connecting strip 130 is composed of at least one fiber layer and at least one coating layer.

Coating 1311 and coating 1312 are polyvinyl chloride (i.e., PVC material) or may be TPU, PET, EVA, polyurethane (PU) or nylon (nylon) material. These materials may be fixedly attached to the inner wall 111 by high frequency welding, hot melt or high strength adhesive or other high strength attachment means.

The fiber layer 1313 comprises a number of fibers or threads, a planar fabric material or a dimensional fabric material. These materials are made of one or several high tensile strength fibers (e.g., natural or chemical fibers). For example, the one or more fibers may be selected from the group consisting of, but not limited to:

Cotton thread (cotton fibers)

Linen (linens)

Silk thread (silk fibers)

Nylon fibers

Polyacrylonitrile fibers (PAN fibers)

-ultra high molecular weight polyethylene fibres (Ultra High Molecular Weight Polyethylene Fiber, UHMWPEF)

It will be appreciated that the nature of natural or chemical fibers is very wide and for the sake of brevity is not explicitly recited herein, but rather provides only a few general examples which do not constitute a limitation to the specific embodiments of the application. Embodiments based on these fibers are included within the scope of the present application.

It will be appreciated that the examples of materials described above can be applied to all of the strip-shaped structural units 130 of the present application.

In other embodiments, the connector strips 130 are all integrally formed of the same material (e.g., polyvinyl chloride or PVC material, or TPU, PET, nylon material).

Fig. 3a schematically shows a structural unit 130 for forming the connecting member 13 of fig. 2 according to an embodiment of the application. In the present embodiment, the structural unit 130 of the connecting member 13 is specifically illustrated by a connecting strip 131 made of a composite layer. The connecting strip 131 is made of three material layers by lamination. Specifically, the connecting bar 131 includes a first cladding layer 1311, a second cladding layer 1312, and a fiber layer 1313. Wherein the first cladding layer 1311 and the second cladding layer 1312 are made of PVC material.

The fiber layer 1313 is sandwiched between the first cladding layer 1311 and the second cladding layer 1312, and the first cladding layer 1311 and the second cladding layer 1312 are bonded through gap gluing between adjacent wires or by welding (e.g., thermal welding or high frequency welding). The fiber layer 1313 has higher tensile properties, and limits deformation of the connecting bar 131 when it is subjected to tensile force, so as to maintain reliability of the inflated product.

The fiber layer 1313 includes a plurality of threads 13131. The wires 13131 are each made of single or multi-ply fibers extending along or generally along a direction parallel to the length of the connecting strip 131, and the plurality of wires 13131 are parallel or substantially parallel to one another.

Alternatively, the wire 13131 is disposed obliquely between the first cladding layer 1311 and the second cladding layer 1312, that is, the wire 13131 is not disposed strictly along the length of the connecting bar 131, but forms an angle with the direction of the length of the connecting bar 131.

Fig. 3b schematically shows a structural unit 130 for forming the connecting member 13 of fig. 2, according to an embodiment of the application. In the present embodiment, the structural unit 130 of the connecting member 13 is specifically illustrated by a connecting strip 132 made of a composite layer. In this embodiment, the connecting strip 132 is also laminated from three layers of material. Specifically, the sheet of material 132 includes a first cladding layer 1321, a second cladding layer 1322, and a fibrous layer 1323. Wherein the fibrous layer comprises a plurality of threads 13231. The wires 13231 are each single-stranded or multi-stranded, differing from the structure of fig. 3a in that the plurality of wires 13231 extend along or substantially along the width of the connecting strip 132, and the plurality of wires 13231 are parallel or substantially parallel to each other.

Fig. 3c schematically shows a structural unit 133 for forming the connecting member 13 of fig. 2, according to an embodiment of the application. In the present embodiment, the structural unit 130 of the connecting member 13 is specifically illustrated by a connecting strip 132 made of a composite layer. The connecting strip 133 is laminated from three layers of material. Specifically, the connection bar 133 includes a first cladding layer 1331, a second cladding layer 1332, and a fiber layer 1333. The construction differs from that of fig. 3a in that the fibrous layer 1333 is a woven mesh structure comprising a plurality of threads 13331 and a plurality of threads 13332. The wires 13331 are each single or multi-stranded, extending along or generally along a direction parallel to the length of the connector strip 133, and the plurality of wires 13331 are parallel or substantially parallel to one another. The wires 13332 are each single or multi-stranded, extending along or generally along a direction perpendicular to the length of the connector strip 133, and the plurality of wires 13332 are parallel or substantially parallel to one another. The threads 13331 and 13332 are interwoven to form the aforementioned mesh structure.

The fiber layer 1333 is interposed between the first cladding layer 1331 and the second cladding layer 1332, and the first cladding layer 1331 and the second cladding layer 1332 are bonded by through holes between the fiber layer 1333 and the network structure of the fiber layer 1333, or are welded (e.g., heat welded or high-frequency welded) by through holes between the network structure of the fiber layer 1333. Thereby firmly fixing the fiber layer 1333 between the cladding layer 1331 and the second cladding layer 1332.

Instead, both the line 13331 and the line 13332 are obliquely disposed between the first and second cladding layers 1331 and 1332, respectively, so that the aforementioned mesh structure is obliquely disposed between the first and second cladding layers 1331 and 1332. That is, the lines 13331 and 13332 form an angle with the direction of the length of the connecting bar 133. It will be appreciated that this feature can be applied in all embodiments of the application.

In another embodiment, the first cladding 1331 is omitted. That is, the fibrous layer 1333 is bonded only with the second cladding layer 1332 by gluing and/or laminating (not shown). The structure of the connecting strip is otherwise the same as that described above. It will also be appreciated that this feature may be applied in all embodiments of the application.

In one embodiment, the cover and the fibrous layer are laminated together by gluing and/or roller means.

In another embodiment, the fiber layer is combined with the coating layer by a laminating method, that is, the fiber layer is immersed in, for example, PVC gum solution and then taken out, the gum solution with irregular surface of the fiber layer is removed, and the composite material required by the strip-shaped structural unit 130 is formed after drying. It will be appreciated that this embodiment can equally be applied in all other embodiments of the application in a suitable manner.

In this embodiment, the connecting strip 133' is laminated from three layers of material. Specifically, connecting bar 133 includes a first cladding layer 1331, a second cladding layer 1332, and a fibrous layer 1333'. Wherein the fibrous layer 1333' comprises a mesh structure comprising a plurality of threads 13335 and a plurality of threads 13336.

Unlike the embodiment shown in fig. 3c, in this embodiment, a plurality of parallel lines 13335 form a first layer of parallel lines and a plurality of parallel lines 13336 form a second layer of parallel lines. The two wire layers are stacked on each other without going through a braiding process, and are disposed between the first cladding layer 1331 and the second cladding layer 1332. Wherein, a plurality of parallel lines 13335 are disposed along the length direction of the connecting piece 133', and a plurality of parallel lines 13336 are disposed along the width direction of the connecting piece 133'. Thus, the production process mode is greatly simplified, and production staff can directly use the wire material for manufacturing, so that the process of weaving the wire material into a net structure is omitted.

In another embodiment, the first cladding 1331 is omitted. That is, the fibrous layer 1333' is bonded only with the second cladding layer 1332 by gluing and/or laminating (not shown). The structure of the connecting strip is otherwise the same as that described above.

Tensioning member

For ease of illustration, the tension member 14 is depicted by FIG. 2 a. The tension members 14 are made of a high tensile material with an elastic modulus (elastic modulus) such that the tension members undergo only a small deformation when subjected to substantial tensile forces. In a preferred embodiment, the tension member 14 is a woven fabric material such that the tension member 14 is attached to the attachment member 13 by stitching.

The fabric material is a plane fabric material or a three-dimensional fabric material and is made of one or more fibers (such as natural fibers or chemical fibers). For example, the one or more fibers may be selected from the group consisting of, but not limited to:

cotton thread (cotton fibers)

Linen (linens)

Silk thread (silk fibers)

Nylon fibers

Polyacrylonitrile fibers (PAN fibers)

It should be understood that the nature of natural fibers or chemical fibers is not explicitly recited herein for the sake of brevity, but rather provides some examples of what are generally known and do not constitute limitations to the embodiments of the application. Embodiments based on these fibers are included within the scope of the present application.

The tension member is directly made of a fabric material, and has better tensile properties than the elastic chemical material. The fabric material may be cotton, hemp, wool, silk or chemical fabrics (e.g. oxford). These fabrics are treated to generally have the ability to retain their properties in a wet environment and can be directly exposed to the air cells of the inflatable product without the need for a continuous coating on the surface during production. Textile materials are generally less expensive to manufacture and lower in weight than the same area of elastane material. In this way, the manufacturing cost and weight of the inflatable product made of the tensioning member is greatly reduced. Meanwhile, the fabric material can use cotton threads or hemp threads and other easily degradable materials, so that the inflatable product is more friendly to the natural environment.

It will be appreciated that the tension members may also be made of a non-woven material. Any material that can be firmly bonded to the connecting member by sewing or bonding is applicable. For example, some leather material with high tensile strength.

Referring to fig. 5a, in one embodiment, the fabric material 141 used to make the tension member 14 is made from a plurality of threads 1411 and 1412 that are interwoven, with the threads 1411 and 1412 being made from one or more fibers (e.g., natural or chemical fibers).

Referring to fig. 5b, in another embodiment, the fabric material 142 used to make the tension member 14 is interwoven from a plurality of wire sets 1421 and a plurality of wire sets 1422. The wire set 1421 includes at least two wires, and the wire set 1422 includes at least two wires. The wires in the wire sets 1421 and 1422 are made of one or several fibers (e.g., natural fibers or chemical fibers), respectively.

Referring to fig. 5c, in another embodiment, the fabric material 143 used to make the tension member 14 is interwoven from a plurality of threads 1431 and a plurality of thread sets 1432. The wire set 1432 includes at least two wires. The wires in the wire set 1432 and the wires 1431 are each made of one or several fibers (e.g. natural fibers or chemical fibers).

Referring to fig. 5d, in another embodiment, the web material 144 used to make the tension member 14 includes an array comprising a plurality of hexagonal cells 1441. Each grid 1441 is defined by a hexagonal frame 14411, respectively, and each hexagonal frame 14411 is defined by one or more fibers, respectively. The cells 1441 in the cell array are staggered and evenly distributed so that the web material 144 has a substantially constant tensile strength in different directions. The hexagonal frame is made of the above-mentioned fibers.

Referring to fig. 5e, in another embodiment, the fabric material 145 used to make the tension member 14 comprises an array comprising a plurality of circular hole cells 1451. Each mesh 1451 is defined by a frame 14511, respectively, and each frame 14511 is defined by one or more fibers, respectively. The cells 1451 in the grid array are staggered and evenly distributed such that the fabric 145 has a substantially constant tensile strength in different directions. The frame is made of the above mentioned fibers.

In some embodiments, the fabric material used to make the tension members 14 is a three-dimensional fabric material. The three-dimensional textile material is typically formed by spatially aligning or entangling fibers. For example, the three-dimensional fabric material is constructed by joining multiple layers of fabric together with binder yarns.

Mounting of tensioning members and connecting members

The various tension members made of, for example, a fabric material as described above, but the tension members made of a fabric material are difficult to be directly fixed to the wall of the inflatable product by means of heat pressing, welding (e.g., thermal welding or high frequency welding), or the like. Although these tensioning members may be secured to the wall of the inflatable product by means of gluing, if the adhesive strength is insufficient, the material sometimes separates at the gluing location in case the inflation pressure of the inflatable product is high.

In view of the above, some embodiments of the present application connect a tensioning member made of a fabric material to a suitable connecting member, wherein the connecting member is capable of being welded to the wall of the inflatable product. Thus, there is a strong connection between the tensioning member and the wall of the inflatable product, allowing the inflatable product to withstand relatively high internal air pressures.

In some embodiments, the tensioning member is connected to the connecting member, the connecting member being connected to the wall of the inflation chamber of the inflatable product, such that the tensioning member is indirectly connected to the wall of the inflation chamber of the inflatable product through the connecting member. For example, the tensioning member is attached to the connecting member by sewing, and the connecting member with which the tensioning member has completed is attached to the wall of the inflation chamber by gluing, heat pressing, welding (e.g., thermal welding or high frequency welding), or other means. In this way, the tension member and the connection member can be reliably connected to the wall of the inflation chamber (e.g., the inner wall 111 and the outer wall 112 of the tank wall 11 of the inflation water tank 1) while keeping the wall of the inflation chamber intact and unbroken, so that the wall of the inflation chamber is less likely to leak at the location of the connection member to cause quality problems of the inflation product.

The following describes a specific embodiment of the present application for installing tension members in an inflatable product, taking as an example the installation of tension members on the inner wall 111 of the tank wall 11 of the inflatable pool 1. These embodiments are applicable to any wall of an inflatable product. Wherein in some embodiments the connecting members used to connect the tensioning members to different walls of the inflatable product (e.g., inner wall 111 and outer wall 112) have the same or substantially the same structure. In other embodiments, the connecting members used to connect the tensioning members to different walls of the inflatable product (e.g., inner wall 111 and outer wall 112) have different structures.

Fig. 6a and 6b exemplarily show a specific structure in which the tension member 14 of fig. 2 is connected with the inner wall of the inflation chamber through the connection member 13 according to one embodiment of the present application. In this embodiment, the tensioning member 14 is secured to the connecting member 13 by one or more stitches 151 in a sewn manner. Fig. 6b is a view in the direction A-A of fig. 6 a. The stitches 151 form two rows of stitches 15, the stitches 15 extending along or substantially along the length of the connecting member 13. The connection member 13 includes a connection bar 131 (refer to fig. 3 a). In this way, the tension member 14 is connected to the connecting bar 131 by sewing. More specifically, the fabric structure of the tension member 14 is reliably connected with the fiber layer in the connecting bar 131 by the sewing thread 151. Subsequently, one coating layer of the connecting strip 131 is connected to the inner wall 111 by means of high-frequency welding.

Alternatively, the threads 13131 are disposed obliquely between the first cladding layer 1311 and the second cladding layer 1312, with the same suture 151 interwoven across the plurality of threads 13131.

Fig. 6c schematically shows a specific structure of the tensioning member 14 of fig. 2 connected to the inner wall of the inflatable chamber by means of the connecting member 13 according to an embodiment of the application. A difference from the embodiment shown in fig. 6a and 6b is that one coating of the connecting strip 131 is omitted. The connecting bar 131' includes a second cladding layer 1312' and a fibrous layer 1313' (see fig. 3 f). The suture 151' secures the tensioning member 14' to the connecting member 13'. The fiber layer 1313' is disposed between the second cladding layer 1312' and the inner wall 111'. The second cladding layer 1312 'is attached to the inner wall 111' by gluing, hot pressing, welding (e.g., thermal welding or high frequency welding), or other means.

It will be appreciated that the number of stitches formed by the suture on the surface of the tensioning member need not be two, but may be more or less and that embodiments are within the scope of the present application.

The specific configurations of the connecting bars 135, 136 and 137 are described with reference to the "connecting members" section.

As an alternative embodiment, one coating of the connecting strip is omitted, one fibrous layer of the connecting strip being in close proximity to the inner wall 111; the barrier layer of the connecting strip is connected to the inner wall 111 by gluing, hot pressing, welding (e.g. heat welding or high frequency welding) or other means.

It will be appreciated that the connecting strips described above may be combined with each other to form the connecting member 13. For example, without limitation, the connection bar 131 shown in fig. 3a, the connection bar 132 shown in fig. 3b, and the connection bar 133 shown in fig. 3c to 3e may be attached to the connection bar 131 'shown in fig. 3f or the connection bar 132' shown in fig. 3g, respectively, to constitute the connection member 13.

Fig. 13a schematically illustrates a specific configuration in which a tensioning member is directly connected to the inner wall of the inflation chamber, in accordance with one embodiment of the present application. The following describes an example of mounting the tension members on the inner wall 211 of the wall of the pneumatic pool. However, the tensioning member is suitable for use with any wall of an inflatable product. Wherein in some embodiments the means for connecting the tensioning means to different walls of the inflatable product have the same or substantially the same structure. In other embodiments, the connecting members used to connect the tensioning members to different walls of the inflatable product have different structures.

Specifically, referring to fig. 13a, the tension member 24 is sewn to the inside surface of the inner wall 211 of the sink wall by one or more stitches. The one or more stitches form a stitch 25. The tension member 24 comprises a fabric material. For example, the tensioning member 24 includes, but is not limited to, a fabric material as shown in any one of fig. 5 a-5 e.

Air leakage may occur due to the sewing process of the outer wall of the inflation chamber, and it is necessary to provide the sealing member 231 attached to the other side of the wall of the inflation product, for example, the other side of the inner wall 211, with respect to the tension member. In some embodiments, the sealing member 231 is substantially entirely made of the same material (e.g., polyvinyl chloride or PVC, or silicone). In other embodiments, the sealing member 231 is composed of at least two materials, for example, the sealing member 231 has the same or substantially the same structure as the connecting strip shown in any one of fig. 3a to 3g, or the sealing member 231 has the same or substantially the same structure as the connecting strip shown in any one of fig. 4a to 4 h.

The sealing member 231 covers the pins 25 to seal the inflation chamber of the inflatable product. Such a configuration for mounting the tension member 24 within the inflatable product may reduce the manufacturing cost of the inflatable product and provide sufficient strength.

Fig. 13a schematically shows a specific structure in which a tensioning member is fixed to the wall of the inflatable product by means of a connecting piece according to an embodiment of the application. The tensioning member is secured to the wall of the inflatable product by a connecting tab. The following describes an example of mounting the tension members on the inner wall 211 of the wall of the pneumatic pool. However, the tensioning member is suitable for use with any wall of an inflatable product. Wherein in some embodiments the means for connecting the tensioning means to different walls of the inflatable product have the same or substantially the same structure. In other embodiments, the connecting members used to connect the tensioning members to different walls of the inflatable product have different structures.

Alternatively, in some embodiments, the tensioning member 24 is disposed between the first end 2322 of the first connection tab 232 and the second end 2332 of the second connection tab 233 and conforms to the first connection tab 232, the second connection tab 233, respectively.

The first connecting piece 232 is made of substantially all of the same material (e.g., polyvinyl chloride or PVC, or silicone), and the second connecting piece 233 is made of substantially all of the same material (e.g., polyvinyl chloride or PVC, or silicone). In other embodiments, the first connecting piece 232 and the second connecting piece 233 are each composed of at least two materials, for example, the first connecting piece 232 and the second connecting piece 233 each have the same or substantially the same structure as the connecting strip shown in any one of fig. 3a to 3g, or the first connecting piece 232 and the second connecting piece 233 each have the same or substantially the same structure as the connecting strip shown in any one of fig. 4a to 4 h.

Referring to fig. 13c, in some embodiments, the tensioning member 24 is not directly connected to the first connection tab 232 or the second connection tab 233, but is indirectly connected to the first connection tab 232 or the second connection tab 233. The tensioning member 24 is secured to the third connecting piece 234 by one or more stitches in a sewn manner. The one or more stitches form stitch 25'. The third connecting piece 234 is made of substantially the same material (e.g. polyvinylchloride or PVC, or silicone), or the third connecting piece 234 is made of at least two materials. For example, the third connecting piece 234 has the same or substantially the same structure as the connecting strip shown in any one of fig. 3a to 3g, or the third connecting piece 234 has the same or substantially the same structure as the connecting strip shown in any one of fig. 4a to 4 h. The third bond pad 234 is attached to the second end 2322 of the first bond pad 232 or the second end 2332 of the second bond pad 233 by gluing, heat pressing, welding (e.g., thermal welding or high frequency welding) or other means. Optionally, the third connecting piece 234 is wholly or partially sandwiched between the first connecting piece 232 and the second connecting piece 233.

Optionally, one of the first connection tab 232 and the second connection tab 233 is omitted in some embodiments.

Alternatively, the stitch 25' is disposed at a connection position of the third connection piece 234 and the first connection piece 232 and/or the second connection piece 233. The suture passes through the tensioning member 24 and the third connecting piece 234, as well as through the first connecting piece 232 and/or the second connecting piece 233.

Fig. 13d schematically shows a specific structure in which one tensioning member is fixed to the wall of the inflatable product by means of a clamping piece, according to one embodiment of the application. The following describes an example of mounting the tension members on the inner wall 211 of the wall of the pneumatic pool. However, the tensioning member is suitable for use with any wall of an inflatable product. Wherein in some embodiments the means for connecting the tensioning means to different walls of the inflatable product have the same or substantially the same structure. In other embodiments, the connecting members used to connect the tensioning members to different walls of the inflatable product have different structures.

Specifically, the tensioning member 24 is sandwiched between the first clamping piece 235 and the second clamping piece 236. The tension member 24 comprises a fabric material. For example, the tensioning member 24 includes, but is not limited to, a fabric material as shown in any one of fig. 5 a-5 e. The tensioning member 24 is adhesively connected to the first and second clamping tabs 235, 236, respectively. Alternatively, the first and second clamp pieces 235, 236 are joined by welding (e.g., heat welding or high frequency welding) in which molten material penetrates through the holes in the tension members 24 to join the first and second clamp pieces 235, 236 so that the first and second clamp pieces 235, 24, 236 are joined together.

The first clamping piece 235 and the second clamping piece 236 are each made of substantially the same material (e.g. polyvinylchloride or PVC, or silicone). In other embodiments, the first and second clamping tabs 235, 236 are each composed of at least two materials, e.g., the first and second clamping tabs 235, 236 each have the same or substantially the same structure as the connecting strip shown in any of fig. 3 a-3 g, or the first and second clamping tabs 235, 236 each have the same or substantially the same structure as the connecting strip shown in any of fig. 4 a-4 h.

Fig. 13e schematically shows a specific structure in which one tensioning member is fixed to the wall of the inflatable product by means of a clamping piece, according to one embodiment of the application. The following describes an example of mounting the tension members on the inner wall 211 of the wall of the pneumatic pool. However, the tensioning member is suitable for use with any wall of an inflatable product. Wherein in some embodiments the means for connecting the tensioning means to different walls of the inflatable product have the same or substantially the same structure. In other embodiments, the connecting members used to connect the tensioning members to different walls of the inflatable product have different structures.

Specifically, the tension member 24 is sandwiched between the pressing piece 237 and the inner wall 211. The tension member 24 comprises a fabric material. For example, the tensioning member 24 includes, but is not limited to, a fabric material as shown in any one of fig. 5 a-5 e. The clamp tab 237 is joined by welding (e.g., heat welding or high frequency welding) in which molten material penetrates the aperture in the tension member 24 so that the clamp tab 237, the tension member 24 and the inner wall 211 are joined together.

The compression tabs 237 are substantially all made of the same material (e.g., polyvinyl chloride or PVC, or silicone). In other embodiments, the pressure tab 237 is formed of at least two materials, for example, the pressure tab 237 has the same or substantially the same structure as the attachment strip shown in any of fig. 3 a-3 g, or the pressure tab 237 has the same or substantially the same structure as the attachment strip shown in any of fig. 4 a-4 h, respectively.

Fig. 13f schematically shows a specific structure in which a tensioning member is directly fixed to the wall of the inflatable product, according to an embodiment of the application. The following describes an example of mounting the tension members on the inner wall 211 of the wall of the pneumatic pool. However, the tensioning member is suitable for use with any wall of an inflatable product.

Specifically, the first end 243 of the tension member 24 is welded to one wall of the inflatable product (e.g., the inner wall 211 of the tank wall of the inflatable tank) and the second end 244 of the tension member 24 is welded to the other wall of the inflatable product (e.g., the outer wall of the tank wall of the inflatable tank). For example, referring to fig. 13g, the tensioning member 24 includes a plurality of wires 241 and a plurality of wires 242, the wires 241 and 242 interwoven with one another to form a mesh structure. In different embodiments, the mesh structure of the tension member 24 may have different configurations. For example, but not limiting of, the tensioning member 24 in some embodiments has a mesh structure as shown in any one of fig. 5 a-5 e.

The wires 241 are all made of substantially the same material (e.g., polyvinyl chloride or PVC, or silicone), and the wires 242 are all made of substantially the same material (e.g., polyvinyl chloride or PVC, or silicone). In other embodiments, wires 241 and 242 are each made from wire stock 2411. Referring to fig. 13h, the strand 2411 includes a core 24111 and an outer layer 24112. The core is made of one or several fibers, such as natural or chemical fibers. For example, the one or more fibers are selected from, but not limited to, the following materials:

Cotton thread (cotton fibers)

Linen (linens)

Silk thread (silk fibers)

Nylon fibers

Polyacrylonitrile fibers (PAN fibers)

The outer layer 24112 is made of a weldable material so that the wire strands 2411 can be welded to the wall of the inflatable product. The outer layer 24112 is made of, for example, but not limited to, polyvinyl chloride (or PVC) or silicone.

The present application thus far satisfactorily discloses a solution in which a plurality of tensioning arrangements are connected to the inner wall of the inflatable product by means of connecting members. These solutions make more use of materials (e.g. fabrics) that have high tensile strength and are degradable, yet allow them to be connected to the inner wall of the inflatable chamber in a firm manner by means of connecting members or other means, greatly reducing the costs and significantly reducing the proportion of non-degradable material of the inflatable product.

Fig. 14a and 14b exemplarily show a specific structure of a laminate for manufacturing a tension member of an inflatable product according to an embodiment of the present application. The tensioning member is directly connected to at least one wall of the inflatable product. The laminate is composed of at least two materials. For example, the laminate is composed of at least one fibrous layer and at least one cladding layer. The coating is applied to one side surface of the fibrous layer, for example by gluing, welding, hot pressing or other means, the fibrous layer comprising a plurality of fibres or threads, a two-dimensional textile material or a three-dimensional textile material.

Wherein the threads or fibers, the two-dimensional textile material or the three-dimensional textile material in the fiber layers are made of one or several fibers, such as natural fibers or chemical fibers. For example, the one or more fibers are selected from, but not limited to, the following materials:

cotton thread (cotton fibers)

Linen (linens)

Silk thread (silk fibers)

Nylon fibers

Polyacrylonitrile fibers (PAN fibers)

For example, laminate 340 includes two cladding layers and one fibrous layer sandwiched between the two cladding layers. Specifically, referring to fig. 14a and 14c, laminate 341 includes first cladding layer 3411, second cladding layer 3412, and fibrous layer 3413. The fiber layer 3413 includes a plurality of threads 34131. The direction of the tension experienced by the laminate 340 in the tension member 34 is indicated by the arrow. The direction of the wire 34131 is parallel or substantially parallel to the direction of the pulling force and the elongation of the wire 34131 is less than the elongation of the first and second coating layers 3411, 3412 so that the wire 34131 can limit the amount of deformation of the tensioning member 34 in the direction of the pulling force it receives as it is pulled to maintain the reliability of the inflated product. The first end of the tensioning member 34 is connected to one wall of the inflatable product (e.g., the inner wall 311 of the tank wall of the inflatable pool) and the second end of the tensioning member 34 is connected to the other wall of the inflatable product (e.g., the outer wall of the tank wall of the inflatable pool). For example, the tension member 34 is attached to one wall of the inflatable product (e.g., the inner wall 311 of the tank wall of the inflatable pool) by gluing, heat pressing, welding (e.g., heat welding or high frequency welding), or other means.

In some embodiments, the tension members 34 are each provided with a fold at both ends. As shown in fig. 14c, the material of the ends of the tension members 34 are folded over and overlapped, and the overlapped portions are joined together by gluing, heat pressing, welding (e.g., heat welding or high frequency welding) or other means to form a folded portion 341. Folded portion 341

Is attached to one wall of the inflatable product (e.g., the inner wall 311 of the tank wall of the inflatable pool) by gluing, heat pressing, welding (e.g., heat welding or high frequency welding), or other means. The thickness of the folded portion 341 is greater than the thickness of the middle of the tension member 34, has higher strength than the unfolded laminate 340, and is less prone to fatigue crack generation, thereby providing a satisfactory reliability of the inflated product.

Alternatively, the threads in the fibrous layer are arranged in other directions. For example, referring to fig. 14b, laminate 342 includes a first cladding layer 3421, a second cladding layer 3422, and a fibrous layer 3423. The fibrous layer 3423 includes a plurality of threads 34231. The direction of the tension experienced by the laminate 340 in the tension member 34 is indicated by the arrow. The direction of line 34231 is perpendicular or substantially perpendicular to the direction of the pulling force. In other embodiments, line 34231 is disposed obliquely between first cladding layer 3421 and second cladding layer 3422, and line 34231 is neither parallel nor perpendicular to the direction of the pulling force. In other words, the angle between the line 34231 and the direction of the pulling force is acute.

For inflatable products incorporating the tension members 34 described above, it may be possible to enhance the reliability and aesthetics of the arrangement of the tension members 34.

Referring to fig. 14d and 14e, in one exemplary embodiment of the present application, the aerated product is an aerated water pond 3. The aerated water tank 3 comprises a tank wall 31 and a tank bottom 32. The tank wall 31 is connected to the tank bottom 32 and defines a water containing chamber 30. The cell wall 31 includes an inner wall 311, an outer wall 312, and an inflation chamber 315, the inflation chamber 315 being defined between the inner wall 311 and the outer wall 312. For example, the tank wall 31 further includes a top wall 313 and a bottom wall 314, wherein the top wall 313 is connected to an upper end of the inner wall 311 and an upper end of the outer wall 312, respectively, and the bottom wall 314 is connected to a lower end of the inner wall 311 and a lower end of the outer wall 312, respectively, and the inner wall 311, the outer wall 312, the top wall 313, and the bottom wall 314 define an inflation chamber 315. Ambient air enters the inflation chamber 315 through the gas passage provided in the cell wall 31, so that the inflation chamber 315 is inflated. Within the plenum 315 are disposed a number of tensioning member sets, each comprising a tensioning member 34 and a tensioning member 34'. Alternatively, each tensioning building set contains more than two tensioning members. The tension members 34 and 34' are disposed in parallel with a distance therebetween that is substantially less than a distance between adjacent tension member sets. Two or more tension members in the tension member set disperse the tension of the inflatable product's inflatable chamber at the location where it is connected to the tension members, providing a relatively smooth outer surface for the inflatable product and reducing the tension experienced by a single tension member, thereby improving the safety of the inflatable product and extending the service life of the inflatable product.

One end of the tension member 34 is connected to the inner wall 311 and the other end of the tension member 34 is connected to the outer wall 312. One end of the tension member 34 'is connected to the inner wall 311 and the other end of the tension member 34' is connected to the outer wall 312. The tension members 34 and 34' are not stretchable or are difficult to stretch, and the inner wall 311 and the outer wall 312 are pulled toward the inflation chamber 315 by the tension member sets, respectively, so that the tank wall 31 and the inflation chamber 315 can maintain a desired shape.

Each set of tensioning members of the pneumatic pool 3 is disposed vertically within the pneumatic chamber 315 or substantially vertically within the pneumatic chamber 315, the sets of tensioning members being arranged in an array within the pneumatic chamber 315. It should be noted that groups of tensioning members arranged in a vertical direction or substantially in a vertical direction are only used to illustrate specific embodiments of the present application. The tension member sets do not have to be arranged in a vertical direction as shown in fig. 14d and 14 e.

The tension member 34 is connected to two walls of the inflatable product (e.g., the inner wall 311 and the outer wall 312 of the pool wall 31) by folded portions (e.g., folded portions 341) at both ends thereof, respectively.

The tensioning members, connecting members, and manner in which the tensioning members may be assembled in an inflatable product are described in detail above based on an inflatable pool. However, the disclosed tension members, connection members, and tension members are not limited to use in inflatable products, but are also applicable to other inflatable products, including, but not limited to, inflatable toys, inflatable sofas, inflatable mattresses, inflatable standing-up pad boards (SUP pads), and the like. After inflation of the inflatable product, the tensioning members are tensioned and provide a pulling force to limit deformation of the inflatable product, maintaining the inflatable product in a shape.

For example, fig. 15 shows an inflatable mattress 4 that includes a top wall 411 and a bottom wall 412, and also includes side walls 416. The top wall 411, bottom wall 412 and side walls 416 define an inflation chamber 415. Within the plenum 415 are disposed a plurality of tensioning members 44, with the ends of the tensioning members 44 being connected directly or indirectly to the top and bottom walls 411, 412, respectively. The tensioning members 44 are optionally distributed in an array. After inflation of inflatable mattress 4, tensioning members 44 are tensioned and provide a pulling force to limit deformation of top wall 411 and bottom wall 412, maintaining inflatable mattress 4 in a shape.

Fig. 16a and 16b show an inflatable standing skateboard 5 comprising a top wall 511 and a bottom wall 512, and further comprising side walls 516. The top wall 511, bottom wall 512, and side walls 516 define an inflation chamber 515. The standing skateboard also includes an inflation port 517, the inflation port 517 being illustratively provided on the top wall 511 in fig. 16 a. Within the plenum 515 are provided a number of tensioning members 54, with both ends of the tensioning members 54 being connected directly or indirectly to the top wall 511 and the bottom wall 512, respectively. The tension members 54 are optionally distributed in an array. After the inflatable standing skateboard 5 is inflated, the tensioning members 54 are tensioned and provide tension to limit deformation of the top and bottom walls 511 and 512, maintaining the skateboard 5 in a shape.

It will be evident to those skilled in the art that the application is not limited to the details of the foregoing illustrative embodiments, and that the present application may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned. Furthermore, it is evident that the word "comprising" does not exclude other elements or steps, and that the singular does not exclude a plurality. A plurality of units or means recited in the apparatus claims can also be implemented by means of one unit or means in software or hardware. The terms first, second, etc. are used to denote a name, but not any particular order.
