FIGS. 1-4 , a pneumatically inflatable structure according to a first embodiment of the invention is shown generally at 10. The pneumaticallyinflatable structure 10 includes two parallel spaced apart pneumaticend support tubes 12 and twoopposed pairs 20 of bowed and criss-crossedpneumatic bracing tubes 22 covered by acanopy 30. In one embodiment of the invention,end support tubes 12 and bracingtubes 22 are substantially identical as better described below. The pneumaticallyinflatable structure 10 may also include a base surface such asbase sheet 16. - The pneumatic
end support tubes 12 include ends 12 a secured tobase sheet 16 or to the ground and are bowed when inflated so as to have an apex 18 be also downwardly concave. Thepneumatic support tubes 12 are arranged in parallel to each other so as to define acommon opening 8 thereunder sized for mid to large sized vehicles including vehicles, boats and the like. The pneumaticallyinflatable structure 10 may also include one or moreintermediate support tube 13 secured to the base sheet or ground which are oriented and bowed in parallel to the end support tubes and so as to also have an apex 18. As illustrated inFIG. 2 , oneintermediate support tube 13 is utilized and located at thejunctions 24 of the two pairs of the bracing tubes, although it will be appreciated that more than one intermediate support tube may also be utilized at different locations between theend support tubes 12.Advantageously tubes - Each
pair 20 ofpneumatic bracing tubes 22 are criss-crossed at correspondingjunctions 24 in fluid communication with one another by a cooperating hollowflexible conduit 26. The first and second opposite ends 22 a and 22 b, respectively oftubes 22 are mounted to opposed pneumaticend support tubes 12, that is, to the end support tubes at each end ofstructure 10. The first ends 22 a are each connected to a base 12 a for example by the use of securing means such asflexible end flap 64 formed at the end of each of the tubes. The second ends 22 b are each connected toapex 18 of thetube 12 at the opposite end ofstructure 10, for example by the use of flexible end flaps 64 formed at the end of each of the tubes, so that eachtube 22 extends the length of, and generally diagonally across each lateral side of thestructure 10. The bracingtubes 22 may be secured to each other as well as to thesupport tubes - Each of the pneumatic
end support tubes 12 are bowed and arranged parallel to each other so as to form a frame having downwardly concave elongate structure defining acommon opening 8.Intermediate support tube 18 are bowed and oriented in parallel to theend support tubes 12 so as to support a middle portion of thecanopy 30. Thepneumatic bracing tubes 22 extend between and brace theend support tubes 12 so as to maintain them in their desired parallel orientation. Thus taken in combination the twoopposed pairs 20 ofpneumatic bracing tubes 22 and theend support tubes 12 define an elongate open enclosure elongate along longitudinal axis A. - Referring to
FIG. 4 ,canopy 30 comprises a rectangular substantially planar flexible sheet of material having first and second end edges 32 and 34, respectively and first and second side edges 36 and 38, respectively. The canopy includes a plurality of securingstraps 40 attached to a bottom surface thereof. The securing straps 40 comprise an elongate strip of material having first and secondfastenable portions intermediate support tubes tubes 22 and serve to secure thecanopy 30 thereto. As illustrated inFIG. 1 , thecanopy 30 also includeend flanges 46 extending inwardly from the canopy so as to surround thesupport tubes 12. - As illustrated in
FIG. 1 , thecanopy 30 includes anexterior surface 31 which may include one ormore guy loops 33 for securing a conventional peggedguy wire 35 thereto. It will be appreciated that theguy wires 35 will assist in the lateral stability of theinflated structure 10, in particular when subjected to side loads such as wind, for example. - In an alternative embodiment as illustrated in
FIG. 5 , the pneumaticallyinflatable structure 10 may include a vestibule 50 extending from one or more ends. The vestibule 50 comprises a sheet of material extending from the first orsecond edge canopy 30 to aground securing location 52 at a distance from the first or second end of thestructure 10. The vestibule 50 provides increased wind resistance and security to the structure. The vestibule 50 may be formed as a common sheet with thecanopy 30 or may be a separate sheet that is connected to the canopy when the structure is erected. - The
inflatable structure 10 may include abase sheet 16 comprising a rectangular sheet of material to which the ends 12 a and 12 b of the end support tubes as well as the ends of theintermediate support tubes 13 and the bracingtubes 22 may be secured. Thebase sheet 16 may provide the dimensions of the base of theinflatable structure 10 when erected. Alternatively theinflatable structure 10 may be secured to the ground by passing afastener 60, such as for example a ground spike through aneyelet 62 in the end flaps 64 of the end orintermediate support tubes tubes 22, as illustrated inFIG. 7 . - In a further embodiment of the present invention, one or more of the
inflatable structures 10 as taught above may be lengthwise connected to each other to form a common modular elongate structure. Where more than oneinflatable structure 10 are employed modularly and each already has a base 16 mounted to the ends of the pairs of tubes, in a further embodiment of the present invention, a separate spanning, joining or linking section is employed to join the adjacent sides of thebase 16. As may be understood then, it is not necessary that the inflatable structure according to the present invention merely and only is limited to twoend support tubes 12 and a single span of bracingtubes 22 as it will be understood that a further elongated enclosure may be constructed using two or more pairs of criss-crossed bracing tubes similar to pairs 20. - In a preferred embodiment, each of the criss-crossed
pneumatic bracing tubes 20 of tube pairs 22, pneumaticend support tubes 12 and pneumaticintermediate support tubes 13 are of a design such as taught in my U.S. Pat. No. 6,263,617 and incorporated herein by reference such that a resilient or at least flexible inner tube is mounted within an outer flexible relatively non-resilient sleeve, and wherein such a sleeve has a folded seam along its interior circumference folded over so that the sleeve and inner tube may be constructed as a linear pole which may then be bent to accommodate the required bowed shaped to form the inflated structure. It has been found that such inflatable tubes for example having approximately a twenty inch circumference which is constant along the length of each tube may be inflated to approximately eight to twelve pounds per square inch (psi) and thereby provide sufficient rigidity for an inflatable structure which may then house wheeled vehicles or towable trailers such as a trailer and boat combination which is not intended to be limiting. - Thus in one embodiment, the width of the span between ends of the pneumatic end and
intermediate support tubes intermediate support tubes intermediate support tubes tubes 22 will thus each be approximately twenty-four feet long. It will be appreciated that other lengths of the pneumatic end andintermediate support tubes pneumatic bracing tubes 22 may also be used for other desired dimensions of the inflatable structure. - In a second embodiment illustrated in
FIG. 6 , the pneumatic end andintermediate support tubes pneumatic bracing tubes 22 may be sized so as to provide a structure having internal dimensions adequate for covering the folded wings of a light aircraft. As illustrated inFIG. 6 , the pneumatic end andintermediate support tubes pneumatic bracing tubes 22 may be approximately 47.3 feet long. Accordingly the structure illustrated inFIG. 6 may therefore be 46 feet long, 32 feet wide and having a height of approximately 16 feet. - An array of
