CASTER DIRECTION-LOCKING MECHANISM FOR MOBILE CART
摘要
CASTER DIRECTION-LOCKING MECHANISM FOR MOBILE CART A caster direction-locking mechanism for a mobile cart improves agility and stability of the cart during high speed movement. This cart includes four casters supporting it for rolling movement. Each caster has a wheel rotatable about a horizontal axis and is mounted with the cart for swiveling movement about a generally vertical axis. The caster direction-locking mechanism selectably locks two adjacent casters against such swiveling movement and with the horizontal axes thereof in generally mutually parallel relation. A handle is mounted on the cart for steering it and an actuator is associated with the handle for actuating the caster direction-locking mechanism to selectably lock and unlock the two casters against swiveling movement. 1253Z/wjm
