Adjustable Drain Assembly

Abstract

An adjustable drain assembly is provided. The assembly includes a base that has a concave inner pivoting surface and a top surface. An upper member is present and has a bottom surface located above the top surface. The upper member may have a concave inner pivoting surface. A pivot component may be present and have a convex outer pivoting surface that engages the concave inner pivoting surface of the base and upper member. The pivot component may be configured for engagement with a cover member. The base may have a pipe engagement surface for engagement with a pipe that is located completely below the pivot component.

What is claimed is: 
     
         1 . An adjustable drain assembly, comprising:

         2 . The adjustable drain assembly of  claim 1  including an inner surface extending from the concave inner pivoting surface and disposed above the pipe engagement surface. 
     
     
         3 . The adjustable drain assembly of  claim 2  wherein the inner surface extending from the concave inner pivoting surface is sloped inward. 
     
     
         4 . The adjustable drain assembly of  claim 2  including a shelf extending from the inner surface. 
     
     
         5 . The adjustable drain assembly of  claim 1  wherein said cover member is adjustably attached to said upper member so that the distance between the top of the cover member and the top of the upper member can be varied. 
     
     
         6 . The adjustable drain assembly of  claim 1  wherein at least a portion of the pivot component includes recesses. 
     
     
         7 . The adjustable drain assembly of  claim 1  wherein said lower step is an outward lower step. 
     
     
         8 . The drain assembly of  claim 1  wherein said upper member and said lower member are removable connected by a bayonet friction coupling. 
     
     
         9 . An adjustable drain assembly, comprising:
 a base having a concave inner pivoting surface that defines a portion of a through bore of the base, wherein the through bore of the base extends from a top surface of the base to a bottom surface of the base, wherein the concave inner pivoting surface extends from the top surface of the base to a location that is not at the bottom surface of the base, wherein the portion of the base defining the concave inner pivoting surface and the portion of the base defining the through bore from the concave inner pivoting surface to the bottom surface of the base are a single component;   an upper member that has a concave inner pivoting surface, wherein the upper member has a through bore;   a pivot component whose position can be adjusted relative to the base and the upper member, wherein the pivot component has a convex outer pivoting surface, wherein at least a portion of the pivot component is located in the through bore of the upper member, wherein the position of the pivot component can be adjusted relative to the base and the upper member to a desired position and then can be locked into place so as to have a fixed position relative to the base and the upper member; and,   a pipe engagement surface that extends from the bottom surface of the base to a lower step that defines a portion of the through bore of the base and is configured for engagement with a pipe.   
     
     
         10 . The adjustable drain assembly of  claim 9  wherein the lower step extends from the through bore through the base extending away from the outer surface of the base. 
     
     
         11 . The adjustable drain assembly of  claim 9  including an inner surface extending from the concave inner pivoting surface and disposed above the pipe engagement surface. 
     
     
         12 . The adjustable drain assembly of  claim 11  wherein the inner surface extending from the concave inner pivoting surface is sloped. 
     
     
         13 . The adjustable drain assembly of  claim 11  including a shelf extending from the inner surface. 
     
     
         14 . The adjustable drain assembly of  claim 11  including a shelf extending into the through bore and carried by an inner surface of the base. 
     
     
         15 . An adjustable drain assembly, comprising:
 a base having a concave inner pivoting surface and a through bore;   a pipe engagement surface included in the base and disposed under the concave inner pivoting surface for attaching a pipe to the base;   an inner step included in the base extended into the through bore;   an upper member that has a concave inner pivoting surface removably attached to the base; and,   a pivot component having a convex outer pivoting surface whose position can be adjusted relative to the base and the upper member and then can be locked into place so as to have a fixed position relative to the base and the upper member.   
     
     
         16 . The adjustable drain assembly of  claim 15  including an outer step included in the base extending away from the through bore. 
     
     
         17 . The adjustable drain assembly of  claim 15  including a cover member removably attached to the pivot component and extendable away from the pivot component to vary the distance between the bottom of the base and the top of the cover component. 
     
     
         18 . The adjustable drain assembly of  claim 15  including a bayonet friction coupling for locking the base and the upper member and securing the pivot component in a desired position. 
     
     
         19 . The adjustable drain assembly of  claim 18  including an upper tab included in the upper member to assist with rotating the upper member relative to the base to lock the upper member and base together. 
     
     
         20 . The adjustable drain assembly of  claim 18  including a lower tab included in the base to assist with rotating the upper member relative to the base to lock the upper member and base together.
