Self draining fitting for a whirlpool bath

Abstract

A whirlpool tub fitting assembly includes a suction cover, a threaded nut, a threaded fitting, and an offset elbow. The fitting assembly is located in a respective aperture in the tub wall. The threaded fitting defines a conduit fitting draft angle of approximately 15 degrees. As tub walls are typically angled at approximately 3-5 degrees and the fitting draft angle is approximately 15 degrees, water within the piping will drain into the tub rather than being retained within the elbow.

1 . A fitting assembly for mounting within a wall of a whirlpool bath comprising: 
 a threaded fitting which defines a first axis, said threaded fitting comprising a conduit which defines a second axis, said second axis transverse said first axis.    
   
   
       2 . The fitting assembly as recited in  claim 1 , wherein said conduit defines an opening offset from a center of a face of said threaded fitting.  
   
   
       3 . The fitting assembly as recited in  claim 1 , wherein said second axis defines an angle of approximately 15 degrees relative said first axis.  
   
   
       4 . The fitting assembly as recited in  claim 1 , wherein said fitting assembly comprises a suction fitting.  
   
   
       5 . The fitting assembly as recited in  claim 1 , wherein said fitting assembly comprises a water jet.  
   
   
       6 . The fitting assembly as recited in  claim 1 , wherein said conduit comprises an inner diameter defined about said second axis.  
   
   
       7 . The fitting assembly as recited in  claim 6 , further comprising an offset elbow receivable within said inner diameter.  
   
   
       8 . A whirlpool bath comprising: 
 a whirlpool bath wall defining a wall draft angle; and    a threaded fitting receivable within said whirlpool bath wall, said threaded fitting defines a first axis generally perpendicular to said whirlpool bath wall and a conduit which defines a second axis angled relative said first axis at a fitting draft angle greater than said wall draft angle.    
   
   
       9 . The whirlpool bath as recited in  claim 8 , wherein said conduit comprises an inner diameter defined about said second axis.  
   
   
       10 . The whirlpool bath as recited in  claim 9 , further comprising a retainer engageable with said threaded fitting to retain said threaded fitting to said whirlpool bath wall.  
   
   
       11 . The whirlpool bath as recited in  claim 10 , further comprising an offset elbow receivable within said inner diameter.  
   
   
       12 . The whirlpool bath as recited in  claim 11 , further comprising a water circulation system in communication with said offset elbow.  
   
   
       13 . The whirlpool bath as recited in  claim 8 , further comprising a water circulation system in communication with said conduit to intake water therethrough.  
   
   
       14 . The whirlpool bath as recited in  claim 8 , further comprising a water circulation system in communication with said conduit to jet water therethrough.  
   
   
       15 . The whirlpool bath as recited in  claim 8 , wherein said second axis defines an acute angle relative said whirlpool bath wall.
