Definitions
- the present disclosure relates to inflatable products and, in particular, to an inflatable product incorporating a durable tensioning structure that is light in weight and low in cost.
- Inflatable products such as inflatable toy structures, inflatable beds, inflatable sofas, inflatable pools and the like are well known in the art. Such products are typically light in weight, easy to pack and store, and easy to carry.
- air beds may incorporate one or more coil-beams or I-beams within the inflatable cavity of the bed. These beams are generally disposed at various locations within the inflatable cavity to shape the bed as the inflatable cavity is pressurized. The beams prevent the air bed from expanding evenly on all sides, similar to that of a balloon. More particularly, in order to maintain the generally rectangular shape of the air bed, these beams may join, for example, upper and lower surfaces of the air bed to one another to restrict their separation during inflation.
- the number and spacing of the beams is proportional to the sharpness of the rectangularity of the inflated product. In other words, the greater the number and/or linear extent of the beams within the inflatable cavity, the “flatter” the bed surfaces become.
- the beam structures are typically made of plastic or PVC sheets with a sufficient thickness to ensure that external loads are spread and concomitant tensile stresses are reduced in the product material.
- conventional inflatable structures utilizing plastic beam structures may meet their desired load requirements by varying the thickness of the beams. This contributes to increased weight of the inflatable product.
- an increase in the thickness and/or spatial density of the beams also increases the compressed/folded volume of the deflated inflatable structure.
- Beam structures made of a solid PVC sheet generally are not strong enough to withstand high pressure loads generated during inflation. Such structures are easily deformed once stretched beyond their elastic limit. This contorts the shape and weakens the strength of the inflatable structure. Further, such beam structures may also rip or tear along seams coupling the beam structures to, for example, the upper and lower surfaces of the inflatable structure if the inflatable structure is over-inflated.
- the inflatable product includes a first sheet, a second sheet disposed opposite the first sheet, where the first sheet and second sheet are spaced apart to define a gap therebetween, and where at least one tensioning structure spans the gap between the first sheet and the second sheet.
- the tensioning structure may include a panel made of a single sheet of porous material, where the panel includes a first end and an opposing second end.
- the tensioning structure may further include a first coupling affixed to the first end of the panel, where the first coupling is also coupled to the first sheet, and a second coupling affixed to the second end of the panel, where the second coupling is also coupled to the second sheet.
- the panel may be made of material having an open cell mesh construction.
- the open cell mesh construction comprises an array of evenly spaced, hexagon-shaped apertures.
- the open cell mesh construction comprises an array of evenly spaced, circular-shaped apertures.
- the first weld sheet and the second weld sheet may each include a first strip of material affixed to a front surface of the panel and a second strip of material affixed to a back surface of the panel.
- the first weld sheet and the second weld sheet may each include a single strip of material folded about the ends of the panel such that one end of the strip of material is affixed to a front surface of the panel and the opposite end of the strip of material is affixed to a back surface of the panel.
- the first end of the panel and the second end of the panel may be coated with PVC or other durable material having favorable bonding characteristics to form coating layers that are coupled to the first sheet and the second sheet.
- the inflatable product may include a first plastic sheet, a second plastic sheet spaced apart from the first plastic sheet, an inflatable air chamber defined by the first plastic sheet and the second plastic sheet, and a plurality of tensioning structures disposed within the air chamber, where each tensioning structure is coupled between the first wall and the second wall.
- Each of the plurality of tensioning structures may include a panel made of a single sheet of porous material, a first weld sheet affixed to a first end of the panel and affixed to the first plastic sheet, and a second weld sheet affixed to a second end of the panel opposite the first weld sheet and affixed to the second plastic sheet.
- the inflatable product may include a first wall, a second wall spaced apart from the first wall, an inflatable air chamber defined by the first wall and second wall, and a plurality of tensioning structures disposed within the air chamber, where each tensioning structure is coupled between the first wall and the second wall.
- Each of the plurality of tensioning structures may include a panels made of single sheet of porous material, a first weld sheet affixed to a first end of the panel and affixed to the first sheet, and a second weld sheet affixed to a second end of the panel opposite the first weld sheet and affixed to the second sheet.
- a method for producing an inflatable product includes the steps of providing a first sheet made of weldable material, and providing a second sheet made of weldable material, where the first sheet is spaced apart from the first sheet to define a gap therebetween.
- the method further includes the step of providing at least one tensioning structure spanning the gap between the first sheet and the second sheet, where the at least one tensioning structure includes a tensile sheet made of porous material.
- the tensile sheet includes a first end and an opposing second end.
- a first weld strip is applied along the first end of the tensile sheet and a second weld strip is applied along the second end of the tensile sheet, where the first weld sheet is coupled to the first sheet and the second weld sheet is coupled to the second sheet.
- the inflatable product is an air mattress having an upper sheet, a lower sheet, and a side wall.
- the method further comprises the steps of creating an inflatable chamber defined by the upper sheet, the lower sheet, and the side wall by coupling the side wall to the upper sheet and coupling the side wall to the lower sheet; and providing a valve in communication with the inflatable chamber to facilitate inflation and deflation of the air mattress.
- the inflatable product is an inflatable spa having an inner wall, an outer wall, a top wall, and a bottom wall.

Description
- This application claims priority of U.S. application Ser. No. 62/002,727, filed on May 23, 2014, titled INTERNAL SUPPORTS FOR INFLATABLE STRUCTURES, which application is incorporated in its entirety by reference in this application.
- 1. Field of Invention
- The present disclosure relates to inflatable products and, in particular, to an inflatable product incorporating a durable tensioning structure that is light in weight and low in cost.
- 2. Background
- Inflatable products such as inflatable toy structures, inflatable beds, inflatable sofas, inflatable pools and the like are well known in the art. Such products are typically light in weight, easy to pack and store, and easy to carry.
- Most inflatable products utilize internal structures in order to form the product into its intended, predetermined shape upon inflation. For example, air beds may incorporate one or more coil-beams or I-beams within the inflatable cavity of the bed. These beams are generally disposed at various locations within the inflatable cavity to shape the bed as the inflatable cavity is pressurized. The beams prevent the air bed from expanding evenly on all sides, similar to that of a balloon. More particularly, in order to maintain the generally rectangular shape of the air bed, these beams may join, for example, upper and lower surfaces of the air bed to one another to restrict their separation during inflation.
- The number and spacing of the beams is proportional to the sharpness of the rectangularity of the inflated product. In other words, the greater the number and/or linear extent of the beams within the inflatable cavity, the “flatter” the bed surfaces become.
- In conventional inflatable products, such as the air beds described above, the beam structures are typically made of plastic or PVC sheets with a sufficient thickness to ensure that external loads are spread and concomitant tensile stresses are reduced in the product material. As such, conventional inflatable structures utilizing plastic beam structures may meet their desired load requirements by varying the thickness of the beams. This contributes to increased weight of the inflatable product. Similarly, an increase in the thickness and/or spatial density of the beams also increases the compressed/folded volume of the deflated inflatable structure.
- Beam structures made of a solid PVC sheet generally are not strong enough to withstand high pressure loads generated during inflation. Such structures are easily deformed once stretched beyond their elastic limit. This contorts the shape and weakens the strength of the inflatable structure. Further, such beam structures may also rip or tear along seams coupling the beam structures to, for example, the upper and lower surfaces of the inflatable structure if the inflatable structure is over-inflated.
- Accordingly, a need therefore exists for a tensioning structure suited for inflatable products that is durable, yet lightweight and easy to manufacture.
- A tensioning structure for use in an inflatable product is provided. In one example, the inflatable product includes a first sheet, a second sheet disposed opposite the first sheet, where the first sheet and second sheet are spaced apart to define a gap therebetween, and where at least one tensioning structure spans the gap between the first sheet and the second sheet. The tensioning structure may include a panel made of a single sheet of porous material, where the panel includes a first end and an opposing second end. The tensioning structure may further include a first coupling affixed to the first end of the panel, where the first coupling is also coupled to the first sheet, and a second coupling affixed to the second end of the panel, where the second coupling is also coupled to the second sheet.
- The panel may be made of material having an open cell mesh construction. In one implementation, the open cell mesh construction comprises an array of evenly spaced, hexagon-shaped apertures. In another implementation, the open cell mesh construction comprises an array of evenly spaced, circular-shaped apertures.
- The first weld sheet and the second weld sheet may each include a first strip of material affixed to a front surface of the panel and a second strip of material affixed to a back surface of the panel. In other implementations, the first weld sheet and the second weld sheet may each include a single strip of material folded about the ends of the panel such that one end of the strip of material is affixed to a front surface of the panel and the opposite end of the strip of material is affixed to a back surface of the panel. In yet another implementation, the first end of the panel and the second end of the panel may be coated with PVC or other durable material having favorable bonding characteristics to form coating layers that are coupled to the first sheet and the second sheet.
- In a second example, the inflatable product may include a first plastic sheet, a second plastic sheet spaced apart from the first plastic sheet, an inflatable air chamber defined by the first plastic sheet and the second plastic sheet, and a plurality of tensioning structures disposed within the air chamber, where each tensioning structure is coupled between the first wall and the second wall. Each of the plurality of tensioning structures may include a panel made of a single sheet of porous material, a first weld sheet affixed to a first end of the panel and affixed to the first plastic sheet, and a second weld sheet affixed to a second end of the panel opposite the first weld sheet and affixed to the second plastic sheet.
- In a third example, the inflatable product may include a first wall, a second wall spaced apart from the first wall, an inflatable air chamber defined by the first wall and second wall, and a plurality of tensioning structures disposed within the air chamber, where each tensioning structure is coupled between the first wall and the second wall. Each of the plurality of tensioning structures may include a panels made of single sheet of porous material, a first weld sheet affixed to a first end of the panel and affixed to the first sheet, and a second weld sheet affixed to a second end of the panel opposite the first weld sheet and affixed to the second sheet.
- A method for producing an inflatable product is further provided. The method includes the steps of providing a first sheet made of weldable material, and providing a second sheet made of weldable material, where the first sheet is spaced apart from the first sheet to define a gap therebetween. The method further includes the step of providing at least one tensioning structure spanning the gap between the first sheet and the second sheet, where the at least one tensioning structure includes a tensile sheet made of porous material. The tensile sheet includes a first end and an opposing second end. A first weld strip is applied along the first end of the tensile sheet and a second weld strip is applied along the second end of the tensile sheet, where the first weld sheet is coupled to the first sheet and the second weld sheet is coupled to the second sheet.
- In one implementation, the inflatable product is an air mattress having an upper sheet, a lower sheet, and a side wall. In the implementation, the method further comprises the steps of creating an inflatable chamber defined by the upper sheet, the lower sheet, and the side wall by coupling the side wall to the upper sheet and coupling the side wall to the lower sheet; and providing a valve in communication with the inflatable chamber to facilitate inflation and deflation of the air mattress.
- In another implementation, the inflatable product is an inflatable spa having an inner wall, an outer wall, a top wall, and a bottom wall. In this implementation, the method further includes the steps of creating an inflatable chamber defined by the inner wall, the outer wall, the top wall, and the bottom wall by coupling the inner wall, the top wall, and the bottom wall, and coupling the outer wall to the top wall and the bottom wall; and providing a valve in communication with the inflatable chamber to facilitate inflation and deflation of the inflatable spa.
- Other devices, apparatus, systems, methods, features and advantages of the disclosure will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description, and be protected by the accompanying claims.

FIGS. 1-9 illustrate examples of different implementations of tensioningstructures 100 employed in inflatable objects. The tensioning structures give shape to inflatable objects, such as inflatable couches, beds, waterslides, structures, or swimming pools. The tensioning structures are lightweight and occupy minimal volume when the inflatable objects are deflated and packed away, while also functioning as strong and durable internal supports upon inflation and use of the inflatable object. - An exemplary tensioning structure in accordance with the present disclosure utilizes thin, flexible I-beam structures that join two areas of fabric to one another. The I-beam structures comprise open cell or mesh material and are firmly connected at their ends to adjacent fabric by an intermediate material, such as a strip of plastic. The intermediate material is in turn firmly attached to the fabric. The area of contact between the intermediate material and the I-beam structure may be adjusted to impart a connection strength commensurate with the tensile strength of the I-beam structure. Similarly, the area of contact between the intermediate material and the adjacent fabric may also be manipulated to impart a fabric/tensioning structure connection strength commensurate with the aggregate tensile strength of all of the I-beams comprising the inflatable object.
- Various tensioning structures are described in detail below. It is contemplated that any of the tensioning structures described herein may be used in any inflatable product, either alone, as a group, or in combination with one another as required or desired for a particular design. In addition, it is contemplated that tensioning structures in accordance with the present disclosure can be used in other contexts, such as in camping, recreational, entertainment, amusement, extreme sports, fall-arrest safety and fire rescue equipment, or in any other context where a lightweight, inflatable structure is needed.
- In one exemplary application shown in
FIGS. 1-5B , the tensioningstructures 100 may include one or more I-beam support structures 102 incorporated into an inflatable product, such as aninflatable air mattress 104. Theair mattress 104 may include atop sheet 106, a ground-contactingbottom sheet 108, and aflexible sidewall 110. Theflexible sidewall 110 may be fixedly connected or welded to the peripheries of thetop sheet 106 and thebottom sheet 108 to form aninflatable chamber 112. Within theinflatable chamber 112, the I-beam structures 102 may be attached to inner surfaces of thetop sheet 106 andbottom sheet 108. The I-beam structures 102, collectively, form channels that help shape and structurally reinforce theinflatable chamber 112. - The
top sheet 106,bottom sheet 108, andsidewall 110 may be constructed of plastic, polyvinyl chloride (PVC), thermoplastic rubber (TPR), polyethylene vinyl acetate (PEVA), ethylene vinyl acetate (EVA), thermoplastic polyurethane elastomer (TPU), neoprene-coated fabric, or any other suitable material. In some implementations, thetop sheet 106 may be overlaid with a layer of fabric, padding, flocking, or other material to provide a sleeping surface for the user. One or more air valves (not shown) may be provided and coupled, for example, to thesidewall 110 for inflating and deflating theinflatable chamber 112. - Although
air mattress 104 is shown as a single layer, the present disclosure may also apply to mattresses having multiple layers (e.g., double layers). In addition to mattresses, tensioning structures of the present disclosure may be used in other inflatable products such as inflatable boats, inflatable islands, floatation devices, swimming pools, inflatable slides, and any other inflatable devices. -
FIG. 2 is a front view of the I-beam structure 102. The I-beam structure 102 may be generally rectangular in shape and include apanel 202 made of a material having fibers that form an open cell mesh construction where the cells may be shaped, cut, or otherwise formed into various geometrical shapes. The I-beam structure 102 acts as a retention member, and functions to limit the outward expansion of the top andbottom sheets 106 and 108 (for example, into a balloon shape) when themattress 104 is filled with air. This type of retention is well known to those skilled in the art of inflatable devices, such as floating devices, air mattresses, and the like. Accordingly, although I-beam retention members are shown herein, other retention members can be used in accordance with the present disclosure, including tufted beam structures, coil-beam structures, X-beam structures, and the like. It is noted that, regardless of the type of retention structure used, the shape and comfort of the inflatable chamber will be directly dependent upon the number of retention structures used therein. - As illustrated in
FIG. 3 , thepanel 202 may comprise acircular mesh array 302. Themesh array 302 may be formed from a plurality offibers 304 that define a plurality of pores orapertures 306 therebetween. While theapertures 306 are illustrated inFIG. 3 as being circular in shape, in other implementations, thefibers 304 may define a plurality ofapertures 306 having other geometric shapes, for example, hexagonal or triangular-shapedapertures 306. When the mattress 104 (FIG. 1 ) is inflated, thereby engaging one or more of the I-beam structures 102, thefibers 304 may be placed in tension to maintain the shape and prevent over-expansion or “ballooning” of themattress 104. - The
fibers 304 may be bundled or arranged in a staggered grid pattern to form a lattice of evenly spaced, circular-shapedapertures 306. Theapertures 306 may be spaced apart and arranged at regular intervals to provide the panel 202 (FIG. 2 ) with a substantially constant tensile strength. - Referring now to
FIG. 4A , thepanel 202 may comprise a skeletal hexagonalcellular mesh array 402. Themesh array 402 may be formed from a plurality offibers 404 that define a plurality of pores orapertures 406 therebetween. - The
mesh array 402 may include a first set of spaced-apart andparallel fiber members 408, a second set of spaced-apart andparallel fiber members 410, and a third set of spaced-apart andparallel fiber members 412. The first, second and third set offiber members apertures 406. - The
fibers 404 may be bundled or arranged in a staggered grid pattern to form a lattice of, evenly spaced, hexagon-shapedapertures 406. Thefiber members FIG. 2 ) with a substantially constant tensile strength. - In some implementations, as shown in
FIGS. 3 and 4A , thefibers fiber bundles 414 may be constructed by knotting or weaving together strands of materials such as twine, wire, string, or threads. - In another example, as shown in
FIG. 4B , thepanel 202 may be formed from a plurality of ligaments orframe members 420 that define a plurality of pores oropen cells 422 therebetween. Theframe members 420 may be arranged in a grid pattern, including a first set of spaced-apart andparallel frame members 424 and a second set of spaced-apart andparallel frame members 426. In this grid pattern, the first set offrame members 424 is transverse to the second set offrame members 426 such that the first set offrame members 424 intersects the second set offrame members 426 at ajunction 428. In example shown inFIG. 4A , the first set offrame members 424 intersects the second set offrame members 426 to form a lattice of, evenly spaced, diamond-shapedopen cells 422.Adjacent frame members 420 may be spaced apart at regular intervals to provide thepanel 202 with a substantially constant tensile strength. The size and shape of eachopen cell 422 may vary depending on the thickness and orientation of the surroundingframe members - In some implementations, the
frame members 420 may comprise a cloth or cast screen or mesh of fabric such as nylon, polyester or other durable material. In other implementations,frame members 420 may be constructed by knotting or weaving together strands of materials such as twine, wire, string, or threads. - Turning back to
FIG. 2 , each I-beam structure 102 may include weld strips 204 and 206 connected to upper and lower ends of thepanel 202. The upper and lower weld strips 204 and 206 are in turn welded to thetop sheet 106 andbottom sheet 108, respectively, such that forces urging thetop sheet 106 andbottom sheet 108 apart are encountered by tension in the open cell structure of thepanel 202. -
FIG. 5A is a cross section of the I-beam structure 102 taken along line 2-2 ofFIG. 2 . As shown, and briefly described above, thestructure 102 may be manufactured as a dual layer structure using a pair of weld strips 204 and 206, both above and below thepanel 202. The weld strips 204 and 206 may comprise relatively thin strips of plastic, PVC, or other durable material. For example, the weld strips 204 and 206 may be constructed to a thickness of 0.20 mm-0.40 mm and a width of 20 mm-40 mm; however, the dimensions of the weld strips may vary depending on the size and inflation pressure of the inflatable product. - The use of two mutually opposed weld strips 204 and 206 employs a gripping action to “sandwich” the
panel 202 therebetween, thereby contributing to a high-strength coupling interface. The weld strips 204 and 206 may be affixed to thepanel 202 using suitable coupling techniques, such as radio-frequency (RF) welding, hot-air coupling (e.g., melting or welding), adhering (e.g., gluing) or other means known in the art. When implemented in an inflatable product, the resulting dual-layer tensioning structure 100 has improved strength and can be welded to thetop sheet 106 andbottom sheet 108, on either side (see e.g.,FIG. 6B ). - In other implementations, as shown in
FIG. 5B , asingle weld strip 502 may be used and folded about the lateral ends of thepanel 202 such that one end of the weld strip is affixed to a bottom surface of thepanel 202 and the opposite end of the strip is affixed to a top surface of thepanel 202. In another implementation, one end of theweld strip 502 may be affixed to a surface of thepanel 202, while an opposing end theweld strip 502 may be coupled to a correspondingtop sheet 106 orbottom sheet 108. In yet another implementation, the end regions covered bywelds strips FIG. 2 may, alternatively, be coated by a plastic or PVC coating or coating of another suitable material, thus forming coating layers that may be welded to thetop sheet 106 andbottom sheet 108, respectively. -
FIG. 6A is a perspective view showing a second example of an implementation of the present disclosure where the tensioning structures includes a number of I-beam structures 602 used in an inflatable structure such as anair mattress 600. Themattress 600 includes a sleeping surface attop sheet 604, and a ground-contactingbottom sheet 606. Themattress 600 further includes asidewall 608 that is fixedly connected or welded to the peripheries of thetop sheet 604 and thebottom sheet 606 to form aninflatable chamber 610. In this example, the I-beam structures 602 may include an opencell mesh fabric 612 having one or more cut-outs 614 such that air may flow past the ends ofstructures 602. -
FIG. 6B is a cross-sectional view of theair mattress 600 ofFIG. 6A . As shown, weld strips 616 and 617 affixed along the lateral ends of themesh fabric 612 are bent to a substantially 90° angle at opposite ends of thefabric 612, such that each lateral end of the I-beam structure 602 may be coupled between thetop sheet 604 and thebottom sheet 606 of theair mattress 600 by, for example, sewing, stitching, RF welding, hot-air coupling, adhering, or other means known in the art. Because each I-beam structure 602 is air permeable, due to the open cell structure of themesh fabric 612, pressurized air flowing into theinflatable chamber 610 is permitted to freely flow from one portion of the chamber to an adjoining portion of the chamber during inflation or deflation, as illustrated byarrows mesh fabric 612 provides tension for maintaining the shape of theair mattress 600 as internal pressure increases, thereby preventing theair mattress 600 from expanding evenly on all sides, similar to a balloon. -
FIG. 7A is perspective view showing a third example of an implementation of the present disclosure where the tensioning structures includes a plurality of coil-beam structures 702 used in an inflatable structure such as anair mattress 700. In this example, themattress 700 includes atop sheet 704 and abottom sheet 706. Themattress 700 further includes asidewall 708 that is fixedly connected or welded to the peripheries of thetop sheet 704 andbottom sheet 706 to form aninflatable chamber 710. The coil-beam structures 702 may comprise an opencell mesh fabric 712. -
FIG. 7B is a cross-sectional view of theair mattress 700 ofFIG. 7A . As illustrated inFIGS. 7A and 7B , the coil-beam structures 702 are arranged in an annular fashion to form a closedcolumnar structure 714. Weld strips 716 may be affixed to axial ends of eachcolumnar structure 714 and flared outwards (i.e., bent outwards forming a substantially 90° angle) such that weld strips 716 may be coupled to thetop sheet 704 and thebottom sheet 706 of theinflatable mattress 700. -
FIG. 8 is a perspective view of aninflatable pool 800 incorporating another example of an implementation of the present disclosure. In this example, the tensioningstructures 802 may include a plurality of I-beam structures 804, each having an open cell mesh construction, incorporated into theinflatable pool 800. Theinflatable pool 800 may include abase sheet 806 with a circular edge and an inflatable hollowannular wall 808 coupled thereabout by, for example, sewing, stitching, heat or weld coupling. Thewall 808 may comprise a hollow shell having an oval, circular, or rectangular shape or the like. There may be further provided a reinforcing ring-shapedinflatable base member 810 coupled to the bottom end of thewall 808. Thebase sheet 806,annular wall 808, andbase member 810 may be constructed of a gas impervious, heat-sealable plastic material, such as PVC or other watertight and airtight material. Theinflatable pool 800 may further incorporate other components not shown or described herein, such as water pumps, valves, piping, and motors known in the art. -
FIG. 9 is a cross-sectional view taken along line 9-9 ofFIG. 8 . As shown both inFIGS. 8 and 9 , theannular wall 808 may include aninner wall 812, anouter wall 814, and an interiorannular cavity 816. The interiorannular cavity 816 is defined by the spacing between the inner andouter sidewalls pool 800 is inflated. Thepool 800 may be inflated through one or more air valves (not shown) formed in one of thesidewalls - Ends of each I-
beam structure 804 may be glued, welded, or otherwise adhered to theinner wall 812 and theouter wall 814 of theannular wall 808, respectively. The I-beam structures 804 may be coupled to theinner wall 812 and theouter wall 814 by an intermediate material, such as the weld strips (i.e., 204, 206, 502, and 716) described above, or other suitable means. The I-beam structures 804 may extend radially between theinner wall 812 and theouter wall 814 at spaced intervals of, for example, 15° to form a series of I-beam supports around the circumference of the interiorannular cavity 816. - The open cell mesh construction of the I-
beam structures 804 permits air admitted through the air valve to communicate with all points around the circumference of theannular cavity 816. In some implementations, the I-beam structures 804 may not extend to the top and/orbottom edges annular wall 808 to provide an additional means for air admitted through the air valve to communicate with all points around the circumference of theannular cavity 816. The I-beam structures 804 provide increased support and strength to theinflated pool 800 so that water of substantial depths can be supported within thepool 800 before thesidewall - The open cell mesh construction of the tensioning structures of the present disclosure provide a weight savings over tensioning structures presently used in inflatable products that comprise solid pieces of material. The construction of the fibers comprising the mesh structure enables tension stresses to be distributed more effectively throughout the tensioning structure. Tensioning structures of the present disclosure are capable of withstanding high tension forces and are adapted to maintain the desired shape and structural integrity of the inflatable product even after surfaces of the inflatable product have been stretched beyond their elastic limit. Tensioning structures of the present disclosure are simple in structure, easy to manufacture, durable, and low in production cost. Tensioning structures of the present disclosure are, further, capable of withstanding high inflation pressure values; thus providing the support surface(s) of the product with an appropriate hardness to provide support and comfort to the user.
- In general, terms such as “coupled to,” and “configured for coupling to,” and “secured to,” and “configured for securing to” and “in communication with” (for example, a first component is “coupled to” or “is configured for coupling to” or is “configured for securing to” or is “in communication with” a second component) are used herein to indicate a structural, functional, mechanical, electrical, signal, optical, magnetic, electromagnetic, ionic or fluidic relationship between two or more components or elements. As such, the fact that one component is said to be in communication with a second component is not intended to exclude the possibility that additional components may be present between, and/or operatively associated or engaged with, the first and second components.
- The present disclosure may be used in any application where a lightweight, packable structure is needed to join two pieces of material that are urged away from one another in use. Although the previous description illustrates particular examples of various implementations, the present disclosure is not limited to the foregoing illustrative examples. A person skilled in the art is aware that the disclosure as defined by the appended claims and their equivalents can be applied in various further implementations and modifications. In particular, a combination of the various features of the described implementations is possible, as far as these features are not in contradiction with each other.
