Abstract
A castored base (18) for an office chair includes a plurality of radially extending legs (300), each leg having a socket or sleeve (308) fixed thereto adjacent an outer end thereof. A castor (302/402) is connected to each socket or sleeve (308), each castor having two wheel portions (312/412) and an axle assembly (316/404). The axle assembly includes an axle (314/414) to which the two wheel portions are rotatably mounted in spaced disposition and including a pin (318/418), wherein the pin (318/418) of each castor is received in a respective socket or sleeve (308) which extends at least in part between the two wheel portions (312/412). Only a small clearance is required between the underside of the legs (300) and the tops of the castors (302/402). Further, low profile legs (300) may be used in the base (18), while still providing the required strength and stability.
