Abstract:
A blow-out resistant tire for a vehicle comprising:a tire having an inside wall and an outside wall, an outer peripheral wall extending between and being integrally coupled to an outer edge of said inside wall and said outside wall, each of said inside and outside walls having a generally circular shape and having a central area having a circular opening therein, an inner peripheral wall extending between and being integrally coupled to an edge of each of said openings such that a generally airtight interior of said tire is defined; an intake valve being in communication with said interior of said tire and being mounted on said outside wall of said tire said intake valve being a one-way air valve; a plurality of intermediate walls being positioned within said tire, each of said intermediate walls extending between and being attached to said inner peripheral wall and said outer peripheral wall such that said intermediate walls radiate outwardly from said inner peripheral wall to said outer peripheral wall, each of said intermediate walls extending between said inside wall and said outside wall such that each of a plurality of substantially air-tight chambers is defined between a pair of adjacent intermediate walls, said plurality of intermediate walls comprising six intermediate walls, each of said intermediate walls and said tire comprising an elastomeric material; a plurality of stop valves each being positioned in one of said intermediate walls and being in communication with a pair of adjacently positioned chambers, each of said stop valves being adapted for closing when a first of the chambers associated with the stop valve has an air pressure greater than a second of the chambers associated with the stop valve, each of said stop valves comprising; a tubular member having a first end and a second end, said tubular member extending through one of said intermediate walls such that each of said ends of said tubular member is positioned in a different chamber, said tubular member having a bore extending therethrough and through said first and second ends, a peripheral wall of said bore having a channel therein extending around said bore and being positioned nearer said second end than said first end of said tubular member, a proximal portion of said bore positioned adjacent to said first end of said tubular member and a distal portion of said bore positioned adjacent to said second end of said tubular member each having a width greater than a width of a middle portion of said bore; a pin being positioned in said bore and having a length greater than a length of said bore and a width smaller than said middle portion of said bore, said pin having a pair of bulbous ends, each of said bulbous ends each having a diameter wider than the width of said middle portion of said bore, wherein a first bulbous end may be removably positioned in said proximal portion of said bore and a second bulbous end may be removably positioned in said distal portion of said bore, said pin having a slot therein positioned generally adjacent to said first bulbous end; a biasing means for biasing said bulbous ends outward of said bore, said biasing means having a first end positioned in said slot and a second end positioned in said channel such that said channel of said peripheral wall of said bore inhibits said biasing means from slipping within said bore and failing to bias said pin, said biasing means being resiliently flexible, said biasing means comprising a spring wound about said pin.
