초록 ▼

The invention is an inflatable tube system, having an inflatable tube in the shape of a cylinder having two ends and a shaft. The tube includes a bladder, made of an elastometer in the shape of a cylinder, and a fabric covering made of woven polyethylene, the fabric covering enclosing the bladder. A pair of end closures sealing the fabric covering at the ends of the cylinder. An air valve extends into the bladder through one of the end closures.

대표청구항 ▼

An inflatable tube, comprising: a) a cylindrically-shaped elastomer bladder having a pair of ends and containing an internal cavity, said pair of ends of said cylindrically-shaped elastomer bladder having a plurality of circumferencially disposed throughbores; b) a cylindrically-shaped woven polyethylene fabric casing having a pair of ends, said pair of ends of said cylindrically-shaped woven polyethylene fabric casing having a plurality of circumferencially disposed throughbores, said cylindrically-shaped woven polyethylene fabric casing covering said cylindrically-shaped elastomer bladder with said plurality of circumferencially disposed throughbores of said pair of ends of said cylindrically-shaped woven polyethylene fabric casing aligning with said plurality of circumferencially disposed throughbores of said pair of ends of said cylindrically-shaped elastomer bladder, so that said cylindrically-shaped elastomer bladder can expand to a high pressure in the range of 50 psi and 500 psi within the confines of said cylindrically-shaped woven polyethylene fabric casing without breaking due to the inherent strength of said cylindrically-shaped woven polyethylene fabric casing; c) a pair of end closures covering said pair of ends of said cylindrically-shaped woven polyethylene fabric casing, each of said pair of end closures having a face corresponding to an end of said pair of ends of said cylindrically-shaped woven polyethylene fabric casing and a lip extending perpendicularly from said face of each of said pair of end closures and along said cylindrically-shaped woven polyethylene fabric casing, said lip of each of said pair of end closures having a plurality of circumferencially disposed throughbores aligning with said plurality of circumferencially disposed throughbores of each of said pair of ends of said cylindrically-shaped woven polyethylene fabric casing and aligning with said plurality of circumferencially disposed throughbores of each of said pair of ends of said cylindrically-shaped elastomer bladder; d) an air valve extending through said face of one of said pair of end closures and in to said internal cavity of said cylindrically-shaped elastomer bladder and being in fluid communication therewith; e) a plurality of rivets having a plurality of rivet heads, said plurality of rivet heads of said plurality of rivets disposed in said internal cavity of said cylindrically-shaped elastomer bladder, said plurality of rivets passing through said plurality of circumferencially disposed throughbores of said lip of each of said pair of end closures, passing through said plurality of circumferencially disposed throughbores of said pair of ends of said cylindrically-shaped woven polyethylene fabric casing, and passing through said plurality of circumferencially disposed throughbores of said pair of ends of said cylindrically-shaped elastomer bladder, so that said pair of end closures, said cylindrically-shaped woven polyethylene fabric casing, and said cylindrically-shaped elastomer bladder are fastened together simultaneously; and f) a plurality of washers disposed between said plurality of rivet heads and said cylindrically-shaped elastomer bladder, so that said plurality of rivet heads are prevented from pulling through said cylindrically-shaped elastomer bladder.
