| Zusammenfassung: | The application discloses a caster assembly which includes a caster support leg, a protective shell, a wheel and an axle bolt. The protective shell has a caster support leg housing to receive the caster support leg therein and a sloped side, and the wheel has a tread, a hub and a bearing. The axle bolt secures the caster support leg and the protective shell to the wheel. The caster support leg housing has an upper base, a lower base, and a side wall. The upper base is substantially flat and parallel to the axis of the hub whereas the lower base extends flat from an end of the side wall to form a flat portion and then downwardly sloped toward an inlet of the caster support leg housing. In addition, the sloped side extends downwardly from the upper base toward the tread of the wheel. |
