Total Claims: 9
Claim 1
Independent Claim
178 words
A hydromassaging apparatus comprising in combination a tub having a two-level bottom wall defined by two successive essentially flat surfaces interconnected to one another by a transverse ramp of limited extent, a front inclined wall having a shallow depression centrally thereof, an essentially vertically extending end wall and two lateral walls extending essentially vertically, compressed air supply means located adjacent said tub, longitudinally extending air distribution duct means secured to the outside surface of said tub peripherally thereof along the base of said front wall, end wall and lateral walls, said duct means also comprising air distribution branches disposed immediately adjacent said transverse ramp, and a plurality of small apertures extending through said tub from said air distribution ducts means, said apertures being evenly spaced apart along the base of said lateral walls there being at least two such apertures at spaced apart locations in said ramp, said air distribution duct means also comprising extensions behind the base of said front wall leading to apertures disposed at spaced apart locations of said shallow depression toward the base thereof.
Claim 2
Dependent Claim
178 words
A hydromassaging apparatus comprising in combination a tub having a two-level bottom wall defined by two successive essentially flat surfaces interconnected to one another by a transverse ramp of limited extent, a front inclined wall having a shallow depression centrally thereof, an essentially vertically extending end wall and two lateral walls extending essentially vertically, compressed air supply means located adjacent said tub, longitudinally extending air distribution duct means secured to the outside surface of said tub peripherally thereof along the base of said front wall, end wall and lateral walls, said duct means also comprising air distribution branches disposed immediately adjacent said transverse ramp, and a plurality of small apertures extending through said tub from said air distribution ducts means, said apertures being evenly spaced apart along the base of said lateral walls there being at least two such apertures at spaced apart locations in said ramp, said air distribution duct means also comprising extensions behind the base of said front wall leading to apertures disposed at spaced apart locations of said shallow depression toward the base thereof.
Claim 3
Dependent Claim
38 words
Hydromassage tub as defined in claim 1 wherein said transverse ramp is located essentially at equal distance from said end wall and said front wall, and defines a smooth transition from the two levels of said bottom wall.
Claim 4
Dependent Claim
69 words
Hydromassage tub as defined in claim 1 wherein said duct means is defined by two laterally extending preformed troughs adequately secured to the outer surface of said tub adjacent the bottom of said lateral walls extending behind said front wall behind said end wall, each trough including a branch forming section secured to the lower surface of said transverse ramp and defining the lowermost portion of said duct means.
Claim 5
Dependent Claim
52 words
Apparatus as defined in claim 3 wherein the lowermost portion of said branch forming section is located at the level or slightly above the highest point of the lower level of said bottom wall, and comprises at least one said aperture essentially level with said lowermost portion of said branch forming section.
Claim 6
Dependent Claim
40 words
Apparatus as defined in any of claims 1, 3 or 4 wherein said compressed air supply means comprises a 180° coupling located immediately below the upper edge of said bathtub and interconnecting said air supply means to said duct means.
Claim 7
Dependent Claim
33 words
Apparatus as defined in claim 1 wherein said compressed air supply means comprises two electric motor driven air blowers permanently connected to a suitable supply of electricity through a ground fault protection breaker.
Claim 8
Dependent Claim
20 words
Apparatus as defined in claim 6 wherein each air blower has a capacity of approximately 100 cubic feet per minute.
Claim 9
Dependent Claim
29 words
Apparatus as defined in claim 1 or 7 comprising a total of approximately 34 apertures, each aperture being of circular cross-section measuring about 3/16 of an inch in diameter.
