Toilet flushing system

Abstract

A toilet flushing system is provided for both high and low volume flush control. The toilet flushing system comprises a control assembly having an actuator, first link, second link, and swivel member that provide high volume flush control by selectively opening a closure member rotatably attached to the housing. The rotation of a lever mobilizes the actuator such that the first link, swivel member, second link, and closure member are rotated from a closed position to a high volume flush position.

1 . A toilet flushing system for providing both high and low volume flush control, the toilet flushing system comprising:
 a lever rotatable to a first position for a low volume flush and rotatable to a second position for a high volume flush;   a central assembly comprising a housing locatable in a toilet cistern selectively enclosing a flush valve for sealing an exit aperture, the flush valve is selectively opened for dispensing water during both the high and low volume flushes through the exit aperture; and   a control assembly comprising an actuator, first link, second link, and swivel member that provide high volume flush control by selectively opening a closure member rotatably attached to said housing, the rotation of the lever to said second position mobilizes said actuator such that said first link, swivel member, second link, and closure member are rotated from a closed position to a high volume flush position.   
   
   
       2 . The toilet flushing system of  claim 1  wherein said rotation of said lever provides translational movement of said actuator resulting in rotational movement of said first link, swivel member, second link, and closure member, the amount of rotational movement in said first link differing from said rotational movement of said second link. 
   
   
       3 . The toilet flushing system of  claim 1  wherein said first link and said second link provide total support of said swivel member. 
   
   
       4 . The toilet flushing system of  claim 1  wherein said swivel member comprises a first link opening for receiving an end portion of said first link and a second link opening for receiving an end portion of said second link, wherein said first link opening is positioned on said swivel member opposite said second link opening. 
   
   
       5 . The toilet flushing system of  claim 1  wherein said swivel member is constructed of nylon and cylindrically shaped wherein a first link opening is positioned on said swivel member diametrically opposite a second link opening. 
   
   
       6 . The toilet flushing system of  claim 1  wherein said swivel member provides independent degrees of rotation of said first link and said second link as said closure member is rotated from a closed position to a high volume flush position. 
   
   
       7 . The toilet flushing system of  claim 6  wherein said independent degrees of rotation of said first link ranges between 0 degrees in the closed position to 110 degrees in the high volume flush position and independent degrees of rotation of said second link ranges between 0 degrees in the closed position to 30 degrees in the high volume flush condition. 
   
   
       8 . A toilet flushing system for providing both high and low volume flush control, the toilet flushing system comprising:
 a lever rotatable to a first position for a low volume flush and rotatable to a second position for a high volume flush;   a central assembly comprising a housing locatable in a toilet cistern selectively enclosing a flush valve for sealing an exit aperture, the flush valve selectively opened for dispensing water during both the high and low volume flushes through the exit aperture; and   a control assembly comprising an actuator, first link, second link, and swivel member that provide high volume flush control by selectively opening a closure member rotatably attached to said housing, said swivel member being totally supported by said first and second links via a first link opening in the swivel member for receiving an end portion of said first link and a second link opening in the swivel member for receiving an end portion of said second link, wherein said first link opening is positioned in said swivel member opposite said second link opening, the rotation of said lever provides translational movement of said actuator resulting in rotational movement of said first link, swivel member, second link, and closure member, the amount of rotational movement in said first link being greater than said rotational movement of said second link to allow for opening of the closure member for a high volume flush.   
   
   
       9 . The toilet flushing system of  claim 8  wherein said swivel member is constructed of nylon and cylindrically shaped wherein a first link opening is positioned on said swivel member diametrically opposite a second link opening. 
   
   
       10 . The toilet flushing system of  claim 8  wherein said swivel member provides independent degrees of rotation of said first link and said second link as said closure member is rotated from a closed position to a high volume flush position. 
   
   
       11 . The toilet flushing system of  claim 8  wherein said first link further comprises a first crank attached to said actuator and a second crank attached to said swivel member, the second crank being larger than said first crank to allow for a wide and quick opening of the closure member with the housing during a high volume flush. 
   
   
       12 . The toilet flushing system of  claim 8  wherein said first link opening and said second link opening are axially offset about said swivel member. 
   
   
       13 . The toilet flushing system of  claim 12  wherein said first link opening and said second link opening are diametrically opposed. 
   
   
       14 . The toilet flushing system of  claim 8  wherein said swivel member comprises a first end attached said first link and a second end attached to a second link and a pivotal axis located between said first and second ends such that said swivel member rotates about said pivotal axis as the lever is rotated to a high volume flush condition. 
   
   
       15 . A toilet flushing system for providing both high and low volume flush control, the toilet flushing system comprising:
 a lever rotatable to a first position for a low volume flush and rotatable to a second position for a high volume flush;   a central assembly comprising a housing locatable in a toilet cistern selectively enclosing a flush valve for sealing an exit aperture, the flush valve selectively opened for dispensing water during both the high and low volume flushes through the exit aperture; and   a control assembly comprising an actuator, first link, second link, and swivel member that provide high volume flush control by selectively opening a closure member rotatably attached to said housing, said swivel member supported by said first and second links via a first link opening for receiving an end portion of said first link and a second link opening for receiving an end portion of said second link, said first and second link openings being axially offset about the swivel member;   the rotation of said lever provides translational movement of said actuator resulting in rotational movement of said first link, swivel member, second link, and closure member, the amount of rotational movement in said first link being greater than said rotational movement of said second link to allow for opening of the closure member for a high volume flush.   
   
   
       16 . The toilet flushing arrangement of  claim 15  wherein said swivel member further comprises a plurality of first and second link openings for accommodating various toilet cistern sizes and configurations. 
   
   
       17 . The toilet flushing arrangement of  claim 15  wherein said swivel member provides independent degrees of rotation of said first link and said second link as said closure member is rotated from a closed position to a high volume flush position. 
   
   
       18 . The toilet flushing system of  claim 17  wherein said independent degrees of rotation of said first link ranges between 0 degrees in the closed position to 110 degrees in the high volume flush position and independent degrees of rotation of said second link ranges between 0 degrees in the closed position to 30 degrees in the high volume flush condition. 
   
   
       19 . The toilet flushing system of  claim 15  wherein said first link and said second link provide total support of said swivel member.
