Abstract

A tool for removing a tire from a wheel rim includes an elongated body member with a handle at one end and a tool head at the other end. The tool head includes a tire engaging member terminating in at least two laterally spaced apart tire contact parts, and a rigid, L-shaped wheel rim engaging member terminating in a wheel rim contact part. The wheel rim contact part is sufficiently spaced from the tire engaging member to accept a wheel rim flange therebetween. In a preferred embodiment, each of the at least two tire contact parts and the wheel rim contact part has a rotatable roller.

Claims

1. A tool for removing a tire from a wheel rim, the wheel rim having axially spaced flanges at a radially outward edge, the tire having axially spaced beads at a radially inward edge, the beads disposed prior to removal between the flanges of the wheel rim, the beads having a circumference smaller than a circumference of the wheel rim, the tool comprising:

an elongated body member defining a handle end and a tool end;

a tool head at the tool end of the elongated body member, the tool head having;

a tire engaging member extending from the elongated body member and terminating in laterally spaced apart tire contact parts dimensioned for insertion between one of the flanges and one of the beads; and

a rigid, L-shaped wheel rim engaging member extending from the tire engaging member and terminating in a wheel rim contact part, said wheel rim contact part being sufficiently spaced from the tire engaging member to accept a wheel rim flange therebetween, said wheel rim contact part, when disposed on the wheel rim, defining a pivot means for enabling pivoting of the tool head about the wheel rim contact part.

2. The tool according to claim 1, wherein the tire engaging member defines at least two laterally spaced apart legs.

3. The tool according to claim 2, wherein the at least two legs diverge as they extend from the elongated body member.

4. The tool according to claim 1, wherein the wheel rim contact part comprises at least one rotatable roller.

5. The tool according to claim 1, wherein at least one of the at least two tire contact parts comprises at least one rotatable

6. The tool according to claim 1, wherein each of the wheel rim contact part and the at least two tire contact parts comprises at least one rotatable roller.

7. The tool according to claim 1, wherein the tire engaging member is L-shaped.

8. The tool according to claim 1, wherein the at least two tire contact parts are disposed substantially along an arc of a tire bead when the wheel rim flange is between the wheel rim contact part and the tire engaging member.

9. A tool for removing a tire from a wheel rim, the wheel rim having axially spaced flanges at a radially outward edge, the tire having axially spaced beads at a radially inward edge, the beads disposed prior to removal between the flanges of the wheel rim, the beads having a circumference smaller than a circumference of the wheel rim, the tool comprising:

an elongated body member defining a handle end and a tool end;

a tool head at the tool end of the elongated body member, the tool head having;

a tire engaging member extending from the elongated body member and terminating in laterally spaced apart tire contact parts dimensioned for insertion between one of the flanges and one of the beads, and wherein each of the tire contact parts comprises at least one rotatable roller;

a rigid L-shaped wheel rim engaging member extending from the tire engaging member and terminating in a wheel rim contact part, wherein the wheel rim contact part comprises at least one rotatable roller which is sufficiently spaced from the tire engaging member to accept a wheel rim flange therebetween, said wheel rim contact part, when disposed on the wheel rim, defining a pivot means for enabling pivoting of the tool head about the wheel rim contact part.

10. The tool according to claim 9, wherein each of the at least one rotatable rollers are cylindrical.

11. The tool according to claim 9, wherein each of the at least one rotatable rollers are conical.

12. The tool according to claim 9, wherein each of the at least one rotatable rollers are spherical.

13. The tool according to claim 9, wherein each of the at least one rotatable rollers has a rotation axis, and the rotation axes are not parallel.

14. The tool according to claim 9, wherein the tire engaging member defines at least two laterally spaced apart legs.

15. The tool according to claim 14, wherein the at least two legs diverge as they extend from the elongated body member.

16. The tool according to claim 9, wherein the tire engaging member is L-shaped.

17. A tool for removing a tire from a wheel rim, the wheel rim having axially spaced flanges at a radially outward edge, the tire having axially spaced beads at a radially inward edge, the beads disposed prior to removal between the flanges of the wheel rim, the beads having a circumference smaller than a circumference of the wheel rim, the tool comprising:

a tool head defining a plane and having a tire engaging member terminating in a bend such that a distal end of the tire engaging member defines laterally spaced tire contact parts disposed at a distance from the plane, the tire engaging member being dimensioned for insertion between one of the flanges and one of the beads;

a rim engaging member disposed on the tool head and having a substantially L-shaped form, the rim engaging member protruding from the plane at a right angle and extending through a right angled bend to a rim contact part, the rim contact part being spaced from the plane a distance at lest as large as a thickness of the wheel rim, said rim contact part, when disposed on the wheel rim, defining a pivot means for enabling pivoting of the tool head about the wheel rim contact part; and

means for allowing a suer to exert a force on the tool head when the tire engaging member is inserted and the rim contact part is disposed on the outside of the rim, for rotating the tool head around the contact part.

18. The tool according to claim 17, wherein the means for allowing a user to exert a force is an elongated handle.

19. The tool according to claim 17, wherein the tool head has two laterally spaced legs defining said plane.

20. The tool according to claim 17, wherein the distal end of at least one of the rim engaging member and the tire engaging member has a roller.
