Patent ID: 8490242

Claim:
An caster alignment system of a mobile device having a fork rotationally connected to a leg of the mobile device, wherein the caster alignment system comprises: a first component operably connected to the leg of the mobile device, wherein the first component includes: a housing having a first end, a second end, a longitudinal through-bore from the first end to the second end forming a sidewall, and an elongated slot through the sidewall extending longitudinally between the first end and the second end; a threadable handle having an end disposable in the longitudinal through-bore of the housing through the first end of the housing, wherein the threadable handle is secured in the first end of the housing, an upper magnet disposed at the second end of the housing opposing the threadable handle; a collar having a through-bore at one end sized to slideably receive the housing; a bolt secured to the one end of the collar and disposed through the elongated slot of the housing such that the end of the threadable handle contacts the bolt as the housing slideably travels longitudinally downward to define an “on” mode and the upper magnet contacts the bolt as the housing slideably travels longitudinally upward to define an “off” mode, wherein the bolt retains the upper magnet to the bolt when the upper magnet is in proximity of the bolt; and a second component operably connected to the fork of the mobile device, wherein the second component comprises a lower magnet on its upper surface, wherein the first and second components are positioned in parallel orientation to each other to form a perpendicular gap between the upper magnet of the first component and the lower magnet of the second component, wherein the magnetic properties of the lower magnet of the second component are a polar opposite of the magnetic properties of the upper magnet of the first component, wherein alignment of a caster rotatably connected to the fork of the mobile device is achieved by an attractive force of the upper magnet of the first component to the lower magnet of the second component when the caster is caused to deviate from a straight path when the caster alignment system is in the “on” mode.
