Abstract: A hydrotherapy jet system includes a fixture body, an air line connector coupled to the fixture body, and a water line connector coupled to the air line connector. The air line connector is provided with structure adapted to couple about the outside of relatively small fixture bodies and about the inside of relatively large fixture bodies. As such, the air line connector is universal for multiple sizes of fixture bodies. The water line connector is coupled to the rear of the air line connector. The air and water line connectors may be rotated relative to the element to which each is coupled to facilitate assembly and plumbing. Other plumbing components and fittings may be coupled in manner which provides a fluidtight seal and permits the components and fitting to thereafter be rotated relative to each other.

Abstract: A coupling system for coupling flexible tubing between ports includes a port element provided with a barb, and a clamp which secures the tubing over the port element. A first end of the clamp is formed as a plurality of axially extending resilient, yet stiff, fingers having a barb at a tip. The fingers are biased slightly inward toward a center of the channel to define an inner diameter which is smaller than the outer diameter of the tubing. A diameter at the second end of the clamp is larger than a diameter of the tubing to allow for easier installation of the tubing through the channel of the clamp. A diameter of a portion of the channel between the first end and the second end is substantially the same or slightly smaller than the diameter of the tubing such that the clamp snugly grips the tubing without affecting the flow through the tubing. In use, the tubing is inserted through the second end of the clamp, and the tubing is then positioned over the barb of the port element.

Abstract: A spa fixture assembly includes a resilient grommet and a fixture. The grommet has a lip, an inner surface, and an outer surface. The fixture may, by way of example, be a skim filter, a speaker system, a water jet assembly, a light fixture, and a suction fitting. The grommet and fixture are non-circular in cross-section. The grommet is inserted in a hole drilled in a tub wall until the lip of the grommet seats flush with the tub wall. The fixture is inserted into the grommet until the lip of the fixture abuts the lip of the grommet. With this design and method of installation no back grinding is required of the drilled hole and no other sealant, such as a gasket, caulking, or o-ring, is required for installation. The entire installation may be completed by one person.

Abstract: A spa enclosure for a spa tub is provided with a cabinet having at least one towel bar or towel hook and which at least partially recesses into the wall of the enclosure. The cabinet is provided with vent openings which permit heat cogenerated by a water pump used to pump water in the spa, an air blower, and/or a water heater to enter the cabinet by convection, heat towels provided on the bars or hooks, and exit through an upper portion of the cabinet. No additional dedicated heating element is provided to heat the towels. According to one preferred embodiment of the invention, the cabinet is hinged at a lower portion to the enclosure and pivots about the hinge to open. The front and sides of the cabinet are preferably insulated to retain heat within the cabinet, and likewise, the enclosure may be insulated. A supply of towels may be kept in the cabinet or towels may be placed in the cabinet just prior to entering the spa tub.

Abstract: A hydrotherapy jet system is provided which generally includes a fixture body, a nozzle, and a fluid line connector. The fixture body is insertable into a hole in a spa tub wall. The nozzle is inserted into a front end of the fixture body. An optional cover may be provided over the front end of the fixture body securing the nozzle in position. The fluid line connector has a first end adapted to be snap fit to a rear portion of the fixture body such that a fluid-tight coupling is provided, and a second end adapted for secure coupling to a flexible plumbing conduit. The fluid line connector is couplable to the fixture body without tools by simply snap-fitting the fluid line connector with the fixture body. An O-ring is preferably provided to one of the rear portion of the fixture body and fluid line connector to ensure the fluid-tight seal. It will be appreciated that after securely coupling the fluid line connector to the fixture body, the fluid line connector is rotatable relative to the fixture body.

Abstract: A hydrotherapy jet assembly includes a resilient grommet and a jet valve body. The grommet has a lip, a body having an inner surface and an outer surface, and a raised bead running the inner surface circumference. The inner surface includes a tapered portion tapering away from the lip. The jet valve body has a water entry port, an air conduit, a lip, and an external circumferential groove for interlocking with the raised bead of the grommet, and a water fitting. According to a method of the invention, the grommet is inserted from the inside of the tub through a hole drilled in a tub wall until the lip of the grommet seats flush with the tub wall. The jet valve body is inserted from the inside of tub until the bead of the grommet interlocks with the groove of the jet valve body and the lip of the jet valve body abuts the lip of the grommet.

Abstract: A spa fixture assembly includes a resilient grommet, a fixture body (e.g., a jet valve body), and a fixture cartridge (e.g., a combined jet valve and cover). The grommet has a body having an inner surface and an outer surface and a lip, with the inner surface preferably tapering away from the lip. The fixture body has a water entry port, an air conduit, a lip, and a threaded insert holder. The fixture cartridge includes a body having external threads, a front peripheral cover, and an insert (e.g., a jet valve). The grommet is inserted from either the front or back of a tub through a hole drilled in a tub wall until the lip of the grommet seats flush with the tub wall. The fixture body is inserted through the grommet (towards the tapered end of the grommet) from the back of tub until the lip of the fixture body seats against the lip of the grommet and is thereby interference fit within the grommet. The fixture cartridge is thread into the fixture body from the front of tub (i.e.

Abstract: Structure for neck and shoulder massage in a hydrotherapy hot tub consists of a pillow element against which a person's head rests with a cavity in the pillow element through which a stream of fluid is directed toward the person's neck. The structure includes a surface interposed in the stream of fluid to deflect the stream to impinge on the person's neck downward at an adjusted acute angle thereto. Another form of the structure includes wing portions extending over the shoulders of a person whose head and neck are at the pillow element with conduits and nozzles at spaced intervals directing streams of fluid downward from the undersides of the wing portions onto the shoulders of the person.
