| 1. A moving jet structure for a spa having a tank with sides containing water for body immersion and a source of pressurized
water, the improvement comprising:
a plurality of flexible tubes connected to the source of pressurized water at a first end, each tube having a second end which
will whip about in reaction to the pressurized water exhausting from the second end;
a plurality of articulated sleeves, an articulated sleeve encircling each one of the plurality of flexible tubes from the
first end to the second end, each sleeve limiting the flexing of the tube to an arc with a change of direction at the end
of the arc;
a manifold connecting together the plurality of articulated sleeves at the second end of the plurality of flexible tubes,
the manifold, in combination with the plurality of articulated sleeves, constraining movement of the plurality of flexible
tubes in unison to a vertical plane;
a plurality of nozzles, one nozzle for each one of the flexible tubes, connected to a flexible tube at the second end, each
nozzle moving in unison with all the other nozzles in a vertical plane, the nozzles exhausting water into the tank from a
side of the tank.
