Abstract
Abstract An improved combination suction elbow assembly and light assembly for use in conjunction with whirlpool bath systems, wherein the embodiment of the invention shown herein is uniquely configured to provide a light assembly which may be readily removed from the inside of the bathtub for replacement of the bulb. The light assembly of the present invention is configured behind a removable deflector with a light transmissive angled surface. The deflector's angled surface minimizes the effect of the light assembly on flow through the suction elbow. In addition, the removable deflector provides a water tight seal connection to prevent any water from reaching the light assembly. A simple tool in the form of an elongated cylinder, having a plurality of wrench pin keys is disclosed. The keys are adapted to engage wrench pins along the peripheral surface of a flange of the removable deflector to enable easy threading and unthreading of the deflector into the housing from inside the tub, without requiring any access from outside the tub.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
125 words
An improved suction assembly for use in whirlpool bath systems of the type installed on a tub, the tub having an interior at least partially filled with water, the suction assembly removing water from the tub through a removable multi-apertured cover while at least one whirlpool jet delivers a mixture of water and air into the tub through a Venturi-type flow channel and a nozzle; the improvement comprising: a light assembly connected to said suction assembly, said suction assembly having at least one light transmissive surface for passing light from said light assembly into said tub interior while preventing water from reaching said light assembly; means for removing said light assembly from said suction assembly from said tub interior for replacement of worn light bulbs.
Claim 2
Dependent Claim
125 words
An improved suction assembly for use in whirlpool bath systems of the type installed on a tub, the tub having an interior at least partially filled with water, the suction assembly removing water from the tub through a removable multi-apertured cover while at least one whirlpool jet delivers a mixture of water and air into the tub through a Venturi-type flow channel and a nozzle; the improvement comprising: a light assembly connected to said suction assembly, said suction assembly having at least one light transmissive surface for passing light from said light assembly into said tub interior while preventing water from reaching said light assembly; means for removing said light assembly from said suction assembly from said tub interior for replacement of worn light bulbs.
Claim 3
Dependent Claim
45 words
The improvement recited in claim 1 wherein said at least one light transmissive surface comprises a light transmissive deflector for receiving said light assembly, the deflector being threadably connected to said suction assembly and having a surface for deflecting water away from said light assembly.
Claim 4
Dependent Claim
32 words
The improvement recited in claim 2 wherein said deflector comprises at least one wrench pin for rotating said deflector for threadably connecting and disconnecting said deflector to and from said suction assembly.
Claim 5
Dependent Claim
43 words
The improvement recited in claim 3 further comprising a tool having one end with at least one wrench pin key for engaging said wrench pin and having another end for grasping said tool from said tub interior while said key engages said pin.
Claim 6
Dependent Claim
84 words
The improvement recited in claim 2 wherein said suction assembly is configured as an elbow having a tub extension and an elbow extension substantially perpendicular to said tub extension for altering the direction of water being removed from said tub, said tub extension and said elbow extension having intersecting axes, said deflector surface being located at about the point of intersection of said axes and forming an angle in the range of about 30 degrees to about 60 degrees with each of said axes.
Claim 7
Dependent Claim
151 words
A suction elbow for use in whirlpool bath systems of the type installed on a tub, the tub having an interior at least partially filled with water, the suction elbow removing water from the tub through a removable multi-apertured cover while at least one whirlpool jet delivers a mixture of water and air into the tub through a Venturi-type flow channel and a nozzle; the improvement comprising: a light assembly connected to said suction elbow, said suction elbow having at least one light transmissive surface for passing light from said light assembly into said tub interior while preventing water from reaching said light assembly; said at least one light transmissive surface comprising a light transmissive deflector for receiving said light assembly, the deflector being threadably connected to said suction elbow for removal from said elbow at said tub interior and having a surface for deflecting water away from said light assembly.
Claim 8
Dependent Claim
151 words
A suction elbow for use in whirlpool bath systems of the type installed on a tub, the tub having an interior at least partially filled with water, the suction elbow removing water from the tub through a removable multi-apertured cover while at least one whirlpool jet delivers a mixture of water and air into the tub through a Venturi-type flow channel and a nozzle; the improvement comprising: a light assembly connected to said suction elbow, said suction elbow having at least one light transmissive surface for passing light from said light assembly into said tub interior while preventing water from reaching said light assembly; said at least one light transmissive surface comprising a light transmissive deflector for receiving said light assembly, the deflector being threadably connected to said suction elbow for removal from said elbow at said tub interior and having a surface for deflecting water away from said light assembly.
Claim 9
Dependent Claim
32 words
The improvement recited in claim 6 wherein said deflector comprises at least one wrench pin for rotating said deflector for threadably connecting and disconnecting said deflector to and from said suction elbow.
Claim 10
Dependent Claim
43 words
The improvement recited in claim 7 further comprising a tool having one end with at least one wrench pin key for engaging said wrench pin and having another end for grasping said tool from said tub interior while said key engages said pin.
Claim 11
Dependent Claim
