  • contact portions 14A and 14B of each of the coils 14 are respectively and securely connected to the upper layer 11 and the lower layer 12 so as to limit movement of the upper layer 11 and the lower layer 12. It is noted that in the conventional arrangement shown in Figs. 1 and 2 , contact portions 14A and 14B must be relatively large in order to securely adhere the straps to the upper and lower layers.
  • a second conventional inflatable device 2 has an upper layer 21, a lower layer 22 and a sidewall 23 connecting a peripheral edge of the upper layer 21 to a peripheral edge of the lower layer 22 so as to form a space between the upper layer 21 and the lower layer 22.
  • multiple straps 24 are provided inside the space between the upper layer 21 and the lower layer 22 to respectively and securely engage a lower face of the upper layer 21 and a top face of the lower layer 22. With the provision of the straps 24, movement of the upper layer 21 as well as the lower layer 22 is limited.
  • each strap is independent from the other.
  • the conventional arrangement of the straps in Figs. 1-4 may result in the waste of material, and can create difficulties in the assembly process.
  • Embodiments of the inflatable device of the present application comprise an upper layer, a lower layer, and at least one strap alternately connected to the upper layer and the lower layer to form a wavelike pattern between the upper layer and the lower layer so as to limit deformation of both the upper layer and the lower layer.
  • the strap comprises a plurality of first contact portions connected to the upper layer, and a plurality of second contact portions connected to the lower layer, wherein the first contact portions are offset from the second contact portions in a horizontal plane respectively defined by the upper layer and the lower layer, such that the first contact portions are not superimposed with the second contact portions from a perspective orthogonal to the upper and lower layers.
  • a preferred embodiment of an inflatable device 3 constructed in accordance with the present application has a upper layer 31, a lower layer 32, and a sidewall 33 connecting an outermost peripheral edge of the upper layer 31 to an outermost peripheral edge of the lower layer 32 so as to form at least one receiving space between the upper layer 31 and the lower layer 32.
  • a plurality of straps 34 are engaged inside the receiving space and connected to the upper layer 31 and the lower layer 32 respectively.
  • the receiving space defines an inflatable bladder or plenum that can be inflated from a deflated stated to an inflated state by an inflator.
  • the material of the upper layer, lower layer, sidewall and straps may be Polyvinyl Chloride (PVC), or any other suitable material known in the art of inflatable products.
  • each strap 34 is a strip of material extending back and forth between the upper layer 31 and the lower layer 32 to form a wavelike pattern when the inflatable device is inflated. Due to the wavelike pattern of the strap 34, each strap 34 is alternately and securely connected to the upper layer 31 and the lower layer 32.
  • each strap 34 is a single, continuous strip of material. As illustrated in Fig. 9 , in other embodiments, each strap 34 comprises a plurality of individual strips connected between the upper and lower layers.
  • each dark contact portion 34A represents the portion of each of the straps 34 contacting the upper layer 31.
  • Each light contact portion 34B represents a projection of the portion of each of the straps 34 contacting the lower layer 32, which from the perspective of Figs. 6 and 7 would be directly below upper layer 31.
  • the contact portions 34A in the upper layer 31 and the contact portions 34B in the lower layer 32 are offset in a horizontal plane respectively defined by the upper layer 31 and the lower layer 32 such that contact portions 34A are not superimposed with the contact portions 34B from a perspective orthogonal to the upper and lower layers.
  • the straps 34 may extend longitudinally or latitudinally relative to the dimensions of the inflatable device. Furthermore, the contact portions connected to a given layer may be aligned in the longitudinal or latitudinal directions as shown in Fig. 6 , or offset in the longitudinal or latitudinal directions as shown in Fig 7 . For any given strap 34, the first contact portion at a distal end of the strap may be connected to the upper layer 31 or the lower layer 32.
  • contact portions 34A and 34B are respectively connected to the upper layer 31 and lower layer 32 by welding.
  • other methods known in the art may be used to adhere the contact portions of the straps to the upper and lower layers.
  • all of the connections of the contact portions 34A with the upper layer 31 and/or all of the connections of the contact portions 34B with the lower layer 32 may be simultaneously welded with a single press of a machine.
  • the inner surface of upper layer 31 and the inner surface of lower layer 32 respectively define an area available for engagement with the contact portions 34A and contact portions 34B of straps 34.
  • An area of the inner surface of the upper layer and/or the lower layer is defined as an available area wherever a load might be applied.
  • the total areas of the contact portions 34A and 34B are respectively greater than or equal to 6.3% of the available areas of the upper layer and the lower layer.
  • the total areas of the contact portions 34A and 34B are respectively less than or equal to 63% of the available areas of the upper layer and the lower layer.
  • an underside of the lower layer 32 of the inflatable device 3 may be free of any support.
  • a protruding peripheral edge 35, 35' may be provided to the underside of the lower layer 32 such that after the inflatable device 3 is inflated, a suction cup is formed under the inflatable device 3.
  • an auxiliary strap 36 may be provided inside the inflatable device 3 and between an inner surface of the sidewall 33 and an inner surface of the lower layer 32, as shown in Fig. 9 .
  • An auxiliary strap 37 may also be provided between an outer surface of the lower layer 32 and the protruding peripheral edge 35', as shown in Fig. 10 .
  • the upper layer, the lower layer and the sidewall 33 form a trapezoidal shape when the inflatable device 3 is inflated.
  • the addition of the auxiliary strap 36 between the inner sidewall of the sidewall 33 and the sidewall of the lower layer 32 reduces or eliminates deformation of the trapezoidal shape.
  • Figs. 8 and 10 illustrate embodiments of the application in which the cross-section of the inflatable device 3 is rectangular.
  • inflatable device 3' has a first auxiliary bar 38 provided at a joint between the upper layer 31 and the sidewall 33 and a second auxiliary bar 38' provided at a joint between the sidewall 33 and the lower layer 32 to enhance the integrity of both the upper layer 31 and the lower layer 32. Furthermore, an upright second inflatable device 3" is securely or detachably connected to the inflatable device 3' depending on the requirements and design differences.
  • each segment 34C of the strap extending between the upper and lower layers is slanted with respect to a reference line orthogonal to the upper layer 31 and the lower layer 32 when the inflatable device is inflated.
  • the angle measured between a segment of the strap forming the contact portion 34A or 34B and a segment 34C of the strap extending between the upper layer 31 and the lower layer 32 is between 91 and 167 degrees. In one preferred embodiment, the angle is 112 degrees. However, it is understood that according to different requirements and designs, any angle larger than 90 degrees and smaller than 180 degrees may be used for the arrangement of the strap 34.
  • each strap 34 is formed into a wavelike pattern with segments extending back and forth between the upper and lower layers.
  • the wavelike pattern has a height H measured from a peripheral edge of a given contact portion 34A in the upper layer to the face to the lower layer, or vice versa.
  • the length of the segment 34C extending from the peripheral edge of a given contact portion 34A in the upper layer to a peripheral edge of an adjacent contact portion 34B in the lower layer (or vice versa) is Y, where H is shorter than Y.
  • X is distance between the peripheral edge of the contact portion 34A in the upper layer projected to the peripheral edge of the adjacent contact portion 34B in the lower layer (or vice versa).
  • the arrangement of straps 34 in a wavelike pattern between upper and lower layers of inflatable device 3 increases the tensile strength of the inflatable device when a load is applied thereon.
  • the wavelike pattern of the straps 34 disclosed in the present application wherein a contact portion 34A in the upper layer 31 shares a single segment 34C of the strap 34 with an adjacent segment 34B in the lower layer 32, allows secure connection of the straps 34 to the upper and lower layers using contact portions 34A and 34B with areas smaller relative to what would be necessary in the conventional coil arrangement shown in Figs. 1 and 2 .
  • the amount of material used in the strap can be reduced relative to the conventional arrangement shown in the Figs. 1-2 .
  • the same amount of material relative to the conventional arrangement shown in the Figs. 1-2 may be used, but more contact portions can be provided, resulting in improved tensile strength of the inflatable device.
  • a total of ninety-nine contact portions may be provided in each of the upper and lower layers with the same amount of material that would allow for only forty eight contact portions in each of the upper and lower layers using the conventional arrangement shown in Figs. 1 and 2 . It is understood that in other embodiments of the application, both material savings and improved tensile strength over the conventional arrangement may be achieved by balancing the amount of material and the number of contact portions according to design requirements.
