Abstract
Described herein is a method for dismounting a tire from a wheel assembly. The method may comprise inserting at least a first finger and a second finger between a top bead of a tire and a top bead seat of a wheel, pulling a portion of at least the top bead past a plane defined by the outer edge of the top bead seat, and moving the first finger in a first rotational direction away from the second finger. Also described herein is a finger for dismounting a tire from a wheel. The finger may comprise at least one roller having two opposing ends, each end connected to a corresponding end of a roller nest of the finger. Also described herein is an apparatus for removing a tire from a wheel. The apparatus may comprise a wheel alignment assembly, a tire dismount assembly, a bead lifter, and a rotation assembly.
Claims17
An apparatus (3010) for removing a tire (1100) from a wheel assembly (1200) comprising:
- a wheel alignment assembly (3100) comprising a shaft (3110), a base pad (3120) comprising a hub (3130), and a first lock mechanism (3140), said shaft having a shaft first end (3112) and a shaft second end (3114) opposite the shaft first end wherein said base pad is connected to the shaft at a shaft location proximate to the shaft second end, and said first lock mechanism is located at the shaft second end;
- a tire dismount assembly (3200) comprising an inner rotator shaft (3210) having an inner rotator shaft first end (3212) and an inner rotator shaft second end (3214), an outer rotator shaft (3220) having an outer rotator shaft first end (3222) and an outer rotator shaft second end (3224), a first sweeper arm (3230) connected to the inner rotator shaft at an inner rotator shaft location proximate to the inner rotator shaft first end, a second sweeper arm (3240) connected to the outer rotator shaft at an outer rotator shaft location proximate to the outer rotator shaft first end, a finger assembly (3250) connected to a bead lifter (3300) said finger assembly comprising a shoe wing (3251) said shoe wing comprising a first wing (3252) and a second wing (3253) said finger assembly further comprising a first finger (3254) removably connected to the first wing, a second finger (3255) removably connected to the second wing, wherein said bead lifter is capable of applying a series of linear forces to the finger assembly;
- a rotation assembly (3400) wherein said rotation assembly is capable of applying a first rotational force in a first rotational direction to the inner rotator shaft and said rotation assembly is capable of applying a second rotational force in a second rotational direction to the outer rotator shaft wherein the first rotational direction is opposite the second rotational direction;
- and
- wherein the inner rotator shaft comprises a second lock mechanism (3216) located at the inner rotator shaft first end, said second lock mechanism configured to interact with the first lock mechanism.
