Abstract
An air jet of an air massage system used with a bathtub having a wall defining opposite visible and hidden surfaces and defining a number of openings through the bathtub wall. The air jet comprises a hollow body having opposed inlet and outlet ends and a unidirectional flow device disposed therebetween. The outlet end is mounted directly to the hidden surface of the bathtub wall opposite one of the openings. The inlet end is connected to a source of pressurized air. The unidirectional flow device allows pressurized air therethrough only in a direction from the inlet to the outlet end and then through the opening in the bathtub wall, thereby preventing water in the bathtub from conveying through the air jet when the source of pressurized air is not in use. The outlet end comprises a flange provided on a downstream side thereof with recesses for receiving an adhesive for securing the flange to the hidden surface of the bathtub wall. The flange comprises an annular seat disposed around an inner wall of the hollow body and blades extending radially outwardly from the annular seat with the recesses extending between the blades and outwardly of the annular seat. The blades and the annular seat contact the hidden surface. The flange also defines a number of holes between the blades for introducing the adhesive in the recesses from an upstream side of the flange. The air jet is connected to an air distribution piping of the air massage system, for instance using fitting. The air jet further comprises an annular seal sandwiched between the upstream side of the flange and a further flange provided at a downstream end of the fitting.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
