  • Castored base for an office chair
    Patent number: 6637072
    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.

  • Arm assembly for a chair
    Publication number: 20020036422
    Abstract: An arm assembly (24) is provided for a chair (12). The chair (12) has a forward direction and a rearward direction. The arm assembly (24) includes an armrest (26) and a support structure (28). A mounting device movably mounts the armrest to the support structure. The mounting device constrains the movement of the armrest (26) relative to the support structure to movement in a substantially horizontal plane having two degrees of freedom defined by first and second transversely arranged axes lying within the substantially horizontal plane. The armrest (26) thus move in a substantially planar fashion without changing the orientation of the armrest (26).
