Abstract
Abstract A therapeutic bath or spa that includes providing aerated streams of water that are injected under pressure into desired areas of the bath receptacle, and a variably positionable occupant support device that can be moved to any desired position relative to the aerated pressure streams to obtain the desired occupant impact pressure and comfort. The spa receptacle includes air and water chambers in tandem integrally formed in a manifold that is coupled around the exterior of the spa receptacle shell, with apertures disposed through the shell and the manifold at desired locations to provide aerated streams of water around the spa. The apertures are repositionable. The periphery of the receptacle shell includes a vertical groove or spaced holes on or near its exterior edge that may encompass the entire receptacle or sections thereof. The occupant support described above may include a resilient, horizontally disposed support and anchor hooks or pins and lines which are fixed to each end of the support for connection into the peripheral groove or holes extending in or around the outside of the spa receptacle shell. The pins or hooks may be anchored at any desired location within the groove or holes thus allowing for alignment and positioning of the occupant support in any direction relative to the inside of the spa and the water jet array within the spa receptacle.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
119 words
A hydrotherapy system having: a waterproof shell defining a receptacle for use as a spa, tub or swimming pool, said shell having means forming a plurality of first holes spaced apart along its interior; and multiple jet manifold means defining a water passageway extending along the outside of said shell at said holes and an air passageway located between said water passageway and the outside of said shell and opening into the interior of the shell through said holes, said manifold means having a second hole leading from said water passageway into said air passageway at each of said first holes to provide aerated impact water through said first holes; said shell forming a wall of said manifold means.
Claim 2
Dependent Claim
119 words
A hydrotherapy system having: a waterproof shell defining a receptacle for use as a spa, tub or swimming pool, said shell having means forming a plurality of first holes spaced apart along its interior; and multiple jet manifold means defining a water passageway extending along the outside of said shell at said holes and an air passageway located between said water passageway and the outside of said shell and opening into the interior of the shell through said holes, said manifold means having a second hole leading from said water passageway into said air passageway at each of said first holes to provide aerated impact water through said first holes; said shell forming a wall of said manifold means.
Claim 3
Dependent Claim
125 words
A hydrotherapy system according to claim 1, wherein: each of said second holes in said manifold means is aligned with and smaller than a corresponding first hole to create a venturi effect; and further comprising: a plurality of plugs removably insertable into aligned first holes and second holes in said manifold means, each of said plugs having a larger segment which is complementary in size and shape to the first hole and having a smaller segment which is complementary in size and shape to the second hole in said manifold means and is positioned for reception in said second hole in said manifold means when said larger segment of the plug is received in the aligned first hole to alter the overall hydrotherapeutic flow pattern.
Claim 4
Dependent Claim
64 words
A hydrotherapy system according to claim 1, wherein: said air passageway and said water passageway extend along the outside of said shell; the outside of said shell defines the inner side of said air passageway; and said air passageway is bounded on its outer side by a wall separating it from said water passageway and formed with said second holes in said manifold means.
Claim 5
Dependent Claim
35 words
A hydrotherapy system according to claim 1 in which said shell defines the outer wall of said manifold means and said first holes are in an inner wall attached to and part of said shell.
Claim 6
Dependent Claim
122 words
In a hydrotherapy system having: a waterproof shell defining a receptacle for use as a spa, tub or swimming pool; the improvement which comprises: means defining a rim extending along the top of said shell on the opposite sides of the receptacle, said rim being formed with an elongated groove extending down from the top of said rim at least partially around the receptacle; and an occupant support means extending between said opposite sides of the receptacle and having flexible lines at its opposite ends attached to fasteners including at least one fastener at one end of said rim removably received in said groove in the rim and at least one fastener in said groove at the opposite end of said rim.
Claim 7
Dependent Claim
122 words
In a hydrotherapy system having: a waterproof shell defining a receptacle for use as a spa, tub or swimming pool; the improvement which comprises: means defining a rim extending along the top of said shell on the opposite sides of the receptacle, said rim being formed with an elongated groove extending down from the top of said rim at least partially around the receptacle; and an occupant support means extending between said opposite sides of the receptacle and having flexible lines at its opposite ends attached to fasteners including at least one fastener at one end of said rim removably received in said groove in the rim and at least one fastener in said groove at the opposite end of said rim.
Claim 8
Dependent Claim
32 words
A hydrotherapy system according to claim 5, wherein: said rim extends around the entire circumference of said shell at the top; said groove extends continuously along the entire length of said rim.
Claim 9
Dependent Claim
35 words
A hydrotherapy system according to claim 1, wherein: the inside of said shell is concave along entire length of said first holes to prevent blockage of said first holes by a person in the receptacle.
Claim 10
Dependent Claim
65 words
A hydrotherapy system according to claim 7, wherein: said air passageway and said water passageway extend substantially horizontally along the outside of said shell; the outside of said shell defines the inner side of said air passageway; and said air passageway is bounded on its outer side by a wall separating it from said water passageway and formed with said holes in said manifold means.
Claim 11
Dependent Claim
116 words
A hydrotherapy system according to claim 8, wherein: each of said holes in said manifold means is smaller than the hole in the shell with which it is aligned; and further comprising: a plurality of plugs removably insertable into aligned holes in the shell and said manifold means, each of said plugs having a larger segment which is complementary in size and shape to the hole in the shell and having a smaller segment which is complementary in size and shape to the hole in said manifold means and is positioned for reception in said hole in said manifold means when said larger segment of the plug is received in the aligned hole in the shell.
Claim 12
Dependent Claim
54 words
A hydrotherapy system according to claim 5 further including manifold means defining a water passageway and an air passageway extending along the outside of said shell, said manifold means having holes leading from said water passageway into said air passageway and aligned holes leading from said water passageway into the interior of said shell.
