ABRASION CONTROLLED CASTER WHEEL

摘要

An abrasion controlled caster wheel is described. When a sideways force is applied to a rear of a grocery shopping or material cart either during normal operation or when gathered in the parking lot, the caster wheel, at the rear position of the cart, will redirect its direction of travel or change its mount rigidity rather than scraping sideways across the wheel circumference.
