Abstract
A tire changing machine of the present disclosure may comprises a chassis base, a rotatable wheel holder, a tower, and an arm. A linear actuator is attached to the tower via a pivoting arm assembly. The linear actuator includes an implement on a lower end of the linear actuator. The arm includes an elongate portion, a coupler, first and second ends, first and second halves, and first and second claws. The coupler is located at a central portion of the elongate portion and is operable to couple the arm to the implement of the linear actuator. The first and second claw are operable to engage a tread portion of a tire.

A tire changing machine, comprising:
- a chassis base;
- a rotatable wheel holder operable to retain a wheel rim;
- a tower extending upward from the chassis base, the tower carrying a linear actuator attached to the tower via a pivoting arm assembly, the linear actuator including an implement on a lower end of the linear actuator;
- an arm including an elongate portion, a coupler at a central portion of the elongate portion operable to couple the arm to the implement of the linear actuator, the arm further including a telescopic portion having first and second ends, a center member defining the central portion, a first outer member extending from the central portion to the first end, a second outer member extending from the central portion to the second end, a first claw coupled to the first end of the telescopic portion of the arm, and a second claw coupled to the second end of the telescopic portion of the arm, the first and second claws being operable to engage a tread portion of a tire;
- wherein the first outer member is configured to receive the center member and includes gear teeth, and the second outer member is configured to receive the first outer member and includes gear teeth;
- and
- wherein the coupler is connected to the center member and comprises a handle with first and second gears rotatably coupled to the handle, the first gear operable to engage the gear teeth of the first outer member, the second gear operable to engage the gear teeth of the second outer member.
