Abstract

The articulated duct (11) for extracting stale air has three flexible joints and is connected by a swivel joint to the fan housing. The duct is balanced on a pivot by a counterweight and a lever. The counterweight is connected to a pulley which is connected by an endless cable to a second pulley attached to the flexible joint. When the arms of the duct are moved in a specified direction, the pulley is rotated so that the counterweight also moves to maintain the balance of the duct. The balance system is unaffected by rotating the duct about the swivel joint.
