Abstract

A tire changing tool including a lever plate having a flat surface terminating at an upturned lip for supporting a tire, a solid handle extending upwardly from the lever plate, and a pair of wheel assemblies mounting the lever plate and having soft rubber tires to resist rotation about their axles such that the tire changing tool will not freely roll.

Claims

1. A tire changing tool comprising a lever plate having sides and front and rear ends, a handle, extending from the rear end of said lever plate, formed from a solid bar bent to form a straight bottom portion secured to said lever plate and an upwardly extending central portion joining a grip portion through a bend in said solid bar, a cross member extending laterally along said lever plate secured to it and said handle in an off-center position such that said tire changing tool rotates about said cross member to move the front end of said lever plate upward, and a pair of wheel assemblies mounted on opposite sides of said lever plate and including axles extending from opposite ends of said cross member and having externally threaded ends, rubber tires frictionally mounted on said axles to resist rolling of said tire changing tool, rubber washers mounted on said axles and contacting said tires, and nuts threaded on the end of each axle to force said washers against said tires, said lever plate including a flat surface extending from said rear end to an upturned lip at said front end of said flat surface being wider than said rear end, a pair of side walls depending from opposite sides of said flat surface and tapering toward a point from said rear end to said front end, and a pair of flanges at the termination of said side walls to strengthen said lever plate tapering toward a point from said rear end to said front end.
