Reconfigurable flapper assembly for toilet flush valve

A flapper assembly for a flush valve for a toilet, the flush valve having a valve seat provided by a valve body, the flapper assembly comprising:

• a seal member having a first side providing a sealing face configured to seal with the valve seat and a second side providing a back support face opposite the first side;
• a frame assembly including:
• a) a main frame operably configured to pivotally attach to the valve body of a toilet;
• b) a seal support body having a seal support flange defining a seal support surface, the seal support surface defining a support plane, the seal member attachable to the frame assembly with the back support face facing the seal support surface of the seal support flange and the sealing face facing away from the seal support surface;
• and
• c) a pivotal connection arrangement pivotally connecting the seal support body to the main frame, the pivotal connection arrangement having a first portion provided by a first arm member of the main frame and a second portion provided by the seal support body, wherein one of the first and second portions is a first pivot pin and the other one of the first and second portions is a first pin receiver, the first pin receiver pivotally receiving the first pivot pin to pivotally connect the seal support body for pivotal movement about a pivot axis to the first arm of the main frame, the pivot axis being substantially parallel to the support plane, the first pivot pin having an outermost pivot surface positioned closest to the seal member, the outermost pivot surface having an outermost extent that is substantially co-planar with the support plane.

A flapper assembly for a flush valve for a toilet, the flush valve having a valve seat provided by a valve body, the flapper assembly comprising:

• a seal member having a first side providing a sealing face configured to seal with the valve seat;
• a frame assembly including:
• a) a main frame operably configured to pivotally attach to the valve body of a toilet for pivotal movement about a pivot axis between a seated position and an unseated position, the main frame including:
• i) a main body having first, second, third and fourth attachment locations, each attachment location having an attachment abutment facing away from the pivot axis, the first and second attachment locations spaced apart a first distance from one another parallel to the pivot axis, the third and fourth attachment locations spaced apart a second distance from one another different than the first distance;
• ii) a first leg having a first body portion selectively attachable to the first and third attachment locations and a first pivot lever attached to the first body portion at a first fulcrum, the first pivot lever including a first lever arm and a first lever abutment, the first pivot lever is configured such that when the first body portion is attached to the first or third attachment location and the first lever arm is moved in a first direction relative to the first fulcrum the first lever abutment disconnects from the attachment abutment of the corresponding one of the first or third attachment locations;
• iii) a second leg having a second body portion selectively attachable to the second and fourth attachment locations, the second leg having a second pivot lever attached to the second body portion at a second fulcrum, the second pivot lever including a lever arm and a second lever abutment, the second pivot lever is configured such that when the second body portion is attached to the second or fourth attachment location and the second lever arm is moved in a first direction relative to the second fulcrum the second lever abutment disconnects from the attachment abutment of the corresponding one of the second or fourth attachment locations.
