Reconfigurable flapper for different sized flush valves

Abstract

A flapper assembly for a flush valve as well as method of assembly are provided. The flapper assembly includes a frame and multiple buoyancy assemblies attachable to the frame so as to adjust the buoyancy of the flapper assembly. The flapper assembly kit may have adjustable legs attachable to the frame. The flapper assembly kit may have multiple seal members for use in sealing with different sized/shaped valve seats of different sized flush valves.

What is claimed is: 
     
         1 . A toilet flapper assembly kit comprising:
 a frame;   a first ballast attachable to a first ballast attachment interface, the first ballast providing a first amount of buoyancy when attached; and   a second ballast attachable to a second ballast attachment interface, the second ballast providing a second amount of buoyancy when attached, the second amount being different than the first amount;   a first seal member removably attachable to the frame having a first characteristic for sealing with a valve seat of a first size flapper valve body;   a second seal member removably attachable to the frame having a second characteristic for sealing with a valve seat of a second size flapper valve body, the second size being different than the first size.   
     
     
         2 . The toilet flapper assembly kit of  claim 1 , wherein the frame includes a first radially outward opening seal mounting groove for mounting the first seal member. 
     
     
         3 . The toilet flapper assembly kit of  claim 1 , wherein the first ballast attachment interface is different than the second ballast attachment interface. 
     
     
         4 . The toilet flapper assembly kit of  claim 3 , wherein the first ballast attachment interface is different than the second ballast attachment interface in that the first ballast attachment interface has a different diameter than the second ballast attachment interface. 
     
     
         5 . The toilet flapper assembly kit of  claim 1 , including a first set of legs operably removably attachable to the frame. 
     
     
         6 . The toilet flapper assembly kit of  claim 1 , wherein the first ballast attachment interface is a radially outward extending projection that provides an undercut region, the first ballast having a radially inward extending projection that extends into the undercut region. 
     
     
         7 . The toilet flapper assembly kit of  claim 6 , wherein the radially outward extending projection and the radially inward extending projection resiliently snap engage to allow for selective removal of the first ballast. 
     
     
         8 . The toilet flapper assembly kit of  claim 1 , wherein the first ballast attachment interface is provided by the frame. 
     
     
         9 . The toilet flapper assembly kit of  claim 8 , wherein the second ballast attachment interface is provided by the frame. 
     
     
         10 . The toilet flapper assembly kit of  claim 1 , wherein the frame includes a radially outward extending first flange portion, the radially outward extending first flange portion and the first seal member forming an axial gap therebetween when the first seal member is mounted to the frame. 
     
     
         11 . The toilet flapper assembly kit of  claim 10 , wherein when the second seal member is mounted to the frame, the second seal member extends radially outward beyond the radially outward extending first flange portion. 
     
     
         12 . The toilet flapper assembly of  claim 1 , wherein first seal member has a first maximum thickness and the second seal member has a second maximum thickness different than the first maximum thickness. 
     
     
         13 . The toilet flapper assembly of  claim 1 , wherein the first size is greater than the second size and the first maximum thickness is greater than the second maximum thickness. 
     
     
         14 . The toilet flapper assembly of  claim 13 , wherein the first size is approximately three inches in diameter and the second size is approximately two inches in diameter. 
     
     
         15 . The toilet flapper assembly of  claim 1 , further including a pair of adjustable legs adjustably attachable to the main frame, the pair of legs being adjustable in at least one of a spacing between the legs or a length of the legs. 
     
     
         16 . The toilet flapper assembly of  claim 1 , wherein the first ballast attachment interface is offset from the second ballast attachment interface. 
     
     
         17 . The toilet flapper assembly of  claim 1 , wherein the first ballast attachment interface is located within the second ballast when the second ballast is attached to the second ballast attachment interface.
