Tire puncture repair apparatus

A tire puncture repair apparatus comprising;

• a mounting unit having a tapped bore,
• an elongated probe having external threads mating with said mounting unit tapped bore, said probe provided with a hollow interior and having opposite distal and proximal open ends with said distal open end adapted to be inserted through a tire puncture from the tread of a tire to the inner surface of a tire casing,
• said probe, upon rotation in opposite directions, is advanced and retracted through the tire puncture,
• attachment elements operable to fixedly secure said mounting unit to the tire adjacent the puncture,
• a rubber boot initially disposed within said probe interior and including a collapsed main body attached to a central stem,
• a piston within said probe hollow interior at said proximal open end and having an aperture therethrough,
• a plunger rod engaging said boot and having an upper end projecting through said piston aperture and above said probe proximal open end,
• a flexible foldable tether joining said boot to said plunger rod, whereby following insertion of said probe distal end through the puncture to the inner surface of a tire casing, subsequent downward displacement of said plunger rod forces said boot main body through the puncture and into an un-collapsed position radially extending in a coextensive manner around the puncture while withdrawal of said plunger rod unfolds and then withdraws said flexible tether through said piston aperture in said probe proximal open end,
• said probe hollow interior adapted to receive a measure of rubber bonding fluid beneath said piston, and
• a drive rod having a lower end insertable into said probe and engageable atop said piston, whereby upon downward displacement of said drive rod said piston forces said rubber bonding fluid to exit said probe distal open end to sealingly attach said boot main body to the tire inner surface juxtaposed the puncture.
