Definitions

  • the present disclosure relates to an inflatable product structure, and in particular to an inflatable product structure which is light in weight and low in cost.
  • Inflatable products are light in weight, easy to house, and easy to carry. Such products technologies have been used for outdoor items and toys, as well as various household goods including inflatable beds, inflatable sofas and the like.
  • inflatable products utilize internal structures in order to form the product into its intended, predetermined shape upon inflation.
  • one type of inflatable bed referred to as a wave-shaped, straight-strip or I-shaped inflatable bed
  • Another type of inflatable bed referred to as a column-type inflatable bed, has tension bands arranged into honeycomb-shaped or cylindrical structures within the inflatable cavity.
  • tension bands disposed in the cavity of the inflatable bed give shape to the bed as internal pressure increases, thereby preventing the inflatable bed from expanding evenly on all sides in the manner of a balloon. More particularly, in order to maintain an inflatable bed as a rectangular shape, the tension bands join the upper and lower surfaces of the inflatable bed to one another. To allow passage of pressurized air to both sides of these joining structures, the tension bands may be formed as belts stretching between the upper and lower surfaces, or as vertical expanses of material with air columns formed therein. The number and spacing of the tension bands is proportional to the sharpness of the rectangularity of the inflated product. That is to say, a greater number and/or linear extent of tension bands within the pressurized cavity results in a more “flat” bed surface.
  • the tension bands are made of PVC sheets with a sufficient thickness to ensure spreading of force and concomitant reductions in stress in the product material.
  • the tension bands of known inflatable beds or sofas may have a thickness of about 0.36 mm.
  • the internal tension bands may have a thickness of about 0.38 mm, while “sandwich” type inflatable swimming pools may have a thickness of 0.7-0.8 mm.
  • the present disclosure provides an internal tensioning structure for use in an inflatable product, and a method for producing the same.
  • the tensioning structure fulfills the basic function of maintaining two adjacent inflatable surfaces in a desired geometric arrangement when the inflatable product is pressurized.
  • the tensioning structure is formed by connecting a pair of plastic strips sheets via spaced-apart strands, such as strings or wires. When pulled taut, the strands provide a high tensile strength between the two opposed plastic strips. At the same time, the plastic strips facilitate a strong, long-lasting weld between the tensioning structure and the inflatable product.

  • the bulk material for tensioning structure 103 may be wound onto a take-up spool for later cutting into a tensioning structure 103 of appropriate size for a particular application.
  • the weld sheet 131 may have a relatively small thickness given the level of internal pressure (and, therefore, tension) expected to be encountered by structure 103 during inflation and use of the product. For example, the thickness may be reduced by 20%-40% with respect known internal tensioning structures lacking strands 32 . Because strands 32 are positioned and configured to bear the tensile loads applied to tensioning structure 103 , weld sheet 131 need only provide for proper positioning and protection of the plurality of strands 32 , such as to avoid knotting or damage of strands 32 during practical use.

  • hook-shaped members 541 are uniformly spaced from one another and arranged at the outer sides of lower pair of weld strips 31 , with each row of hook-shaped members 541 offset with respect to the other row.
  • the continuous strand 532 forms a plurality of end-to-end “V” shaped strands when wrapped around successive hook-shaped members 541 in alternating rows thereof, as shown. That is to say, the corner of each “V” is formed at a respective hook-shaped members 541 , and successive corners traced along continuous strand 532 will alternate between rows of hook-shaped members 541 .
  • a second pair of weld strips 31 ′ are positioned over the first pair of weld strips 31 , respectively, and are clamped thereto such that each “V” shaped corner formed by strand 532 is disposed between one of the first pair of weld strips 31 and the abutting one of the second pair of weld strips 31 ′.

  • tensioning structure 503 may be produced and stored in bulk and later applied to various inflatable products.
  • the length and width of tensioning structure 503 may be trimmed to accommodate the internal length or width of the inflatable product.
  • Fixing strand 532 to the single layer of weld strips 31 may be accomplished in a similar fashion to the single-layer weld strip and weld sheet embodiments described above.
  • tensioning structure 503 may also be provided with at least one reinforcement strand 5 extending along the longitudinal extent of at least one of weld strips 31 , 31 ′. Similar to the uses of reinforcement strands 5 in the embodiments described above, reinforcement strands 5 may be arranged on one of the lower pair of weld strips 31 and/or between the lower and upper pairs of weld strips 31 , 31 ′.
  • a tensioning structure in accordance with the present disclosure has a high tensile strength along the axial extent of the strands 32 , 532 extending between respective weld strips and/or along weld sheets.
  • This high tensile strength is complemented with a full-strength weld between the adjacent material of an inflatable product, which is facilitated by the full surface-area contact provided by the weld strip and/or weld sheet interface between strands 32 , 532 and such adjacent material.
  • the tensioning structure performs well an internal structure of the inflatable product, while facilitating an overall reduction in weight and deflated/folded volume of the inflatable product.
  • a loose arrangement of strands 32 is significantly lighter than a one-piece sheet of comparable size and tensile strength.
  • weld sheets 131 act to ensure a consistent position and arrangement of the plurality of strands 32 (or 532 ), thereby prevent such strands from becoming wound or otherwise entangled with one another.
  • weld strips 31 can be utilized to provide a robust structure for welding the tensioning structure into the inflatable product, thereby ensuring that the high tensile strength offered by the strands of the tensioning structure is fully realized.
  • the use of weld sheet 131 can significantly reduce the weight of the entire inflatable product with respect to a traditional, relatively thicker one-piece sheet which is also responsible for handling tensile loading. In other words, weld sheet 131 reduces by 20%-40% in thickness with respect to an existing tensioning structures having comparable thicknesses of 0.36 mm to 0.8 mm as noted above.
  • tensioning structures 3 have a distance 39 between adjacent tensioning structures 3 .
  • strands 32 have a length 37 that approximates a height 37 of tensioning structures 3 when mattress 10 is inflated.
  • the height of PVC tensioning structures is practically limited by the distance between adjacent PVC tensioning structures. This limitation is the result of the typical manufacturing process wherein the PVC tensioning structures are all aligned on a lower sheet 2 and simultaneously welded to lower sheet 2 . If the PVC tensioning structures are too tall, they will overlap adjacent PVC tensioning structures causing adjacent PVC tensioning structures to be welded together and resulting in dysfunctional PVC tensioning structures.
  • the PVC tensioning structures may be folded in half along their length while one edge is being welded.
  • the maximum height may be increased to slightly less than twice the distance between adjacent PVC tensioning structures (ex. 15 millimeters less than twice the height of the PVC tensioning structure). Providing more than one fold is impracticable.
  • gap portions 33 of tensioning structures 3 are made of strands 32 rather than typical PVC sheets discussed above, they are much more flexible than typical PVC tensioning structures. As a result of this flexibility, mattresses 10 can be readily manufactured having heights 37 greater than twice distance 39 between adjacent tensioning structures 3 .
  • weld strips 31 of each of the plurality of tensioning structures 3 are aligned in their respective position for welding to lower sheet 1 .
  • the other weld strip 31 of these tensioning structures 3 are moved adjacent to the weld strip 31 to be welded as shown in FIG. 33 .
  • strands 32 bunch on top of themselves or on top of nearby strands 32 allowing multiple layers of strands 32 to readily lie on top of one another.
  • height 37 of tensioning structures 3 can be greater than twice distance 39 between tensioning structures 3 .
  • length 37 of strands 32 may be 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6 or more times longer than distance 39 between tensioning structures 3 .
  • loops 41 form in strands 32 during bunching and portions of strands 32 may be positioned under weld strip 31 that is currently not being welded.
  • each strand 32 shown in FIG. 33 only has one loop 41 and is only overlapping one other strand 32
  • each strand 32 may have multiple loops 41 and may overlap multiple other strands 32 , particularly when the distance between stands 32 along weld strips 31 is shorter than that illustrated in FIG. 33 .
  • strands may be collected in piles 43 to account for moving welds strips 31 of each tensioning structure 3 adjacent each other.
  • the turns of piles 43 account for the decreased distance between weld strips 31 when weld strips 31 are moved together.
  • weld strips 31 of each tensioning structure 3 are shifted along the extent or length of tensioning structures 3 as shown in FIG. 36 .
  • tensioning structures 3 may be made taller without interfering with the process of welding tensioning structures 3 to upper and lower sheets 1 , 2 .
  • strands 32 may be longer than shown in FIGS. 33-36 . With such longer strands 32 , more or larger loops 41 ( Fig. 33 ), larger and/or taller piles 43 ( FIG. 35 ), or greater shifting ( FIG. 36 ) may be used to accommodate the longer strands 32 to avoid tensioning structures 3 overlapping during welding.
  • strands 32 When prepared for shipping or storage, mattresses 10 are deflated. During deflation, strands 32 may bunch as shown in FIG. 33 . Further, strands 32 from adjacent tensioning structures 3 will contact each other and may become interleaved with strands 32 from one tensioning structure 3 positioned between strands 32 of another tensioning structure. Further, because strands 32 are very flexible, they collapse readily when contacted by other structures when mattress 10 is deflated for shipping or storage. For example, when strands 32 contact upper or lower sheets 1 , 2 when deflated, they comply to upper and lower sheets 1 , 2 to allow upper and lower sheets 1 , 2 to compact more closely.
  • the overall deflated volume of mattress 10 is reduced when compared to mattresses using PVC sheet tensioning structures.
  • strands 32 from a tensioning structure 3 may become interleaved with strands 32 from the same tensioning structure 32 , loops 41 may form, piles 43 may form, and/or strands 32 may become angled to weld strips 31 in a manner similar to that shown in FIG. 36 .
  • strands 32 when collapsed, may be oriented in different directions with some overlapping as shown in the bottom two strands 32 and other following substantially the same direction as shown in the top three strands 32 . Some strands 32 collapse in directions that are not perpendicular to the extent of weld strips 31 . For example, the lowest-most strand 32 in FIG.
  • the overall folded or deflated volume of mattress 10 may be 8-25% less than comparable mattresses with PVC sheet tensioning structures. According to the preferred embodiment, the volume is about 16% less.
  • a tensioning structure in accordance with the present disclosure is also a low-cost option for imparting a desired structure and shape to an inflatable device.
  • a large reduction in PVC material may be achieved by use of the present tensioning structure, as compared to a one-piece sheet of comparable size and tensile strength.
