  • Patent number: 5848444
    Abstract: An articulated jet structure which is mountable on the wall of a tub or spa, and which can be moved into a variety of positions to deliver a pulsed air/water stream to a desired location. More specifically, the hydrotherapy jet which extends from the wall of the hydrotherapy spa can be directed to any number of desired positions and will maintain the desired position while the pulsed air/water stream is delivered to the spa occupant. The hydrotherapy jet comprises a housing and an articulated or flexible section. The mixing of water and air occurs in the housing forming an air/water stream which is delivered to the articulated section of the jet. The articulated section of the jet preferably comprises a plurality of articulating elements interconnected to provide a wide range of motion and which hold their position when released. These elements form a water tight conduit and deliver the air/water stream from the housing to a discharge nozzle on the end of the articulated section.
