Toilet overflow check system

Abstract

A toilet overflow check system having a toilet bowl rim engagement member, a pivot adjustment upright member extending downward from the rim engagement member, an elongate pivot member having a proximate end portion and a distal end portion, a pivot member float mounted on the distal end portion of the elongate pivot member, and having a centrally located pivot point, and a pivot axle supported by the pivot adjustment upright member. The pivot axle pivotally supports the elongate pivot member at the pivot point, and there is a connecting cord secured to the proximate end portion of the elongate pivot member, the connecting cord being connected to the flap member of a flap valve of the toilet. In operation, upon the float rising upward with water approaching an overflow condition, the elongate pivot pulls the connecting cord, closing the toilet flap valve.

1 . A toilet overflow check system, comprising: 
 a toilet bowl rim engagement member;    a pivot adjustment upright member extending downward from said rim engagement member;    an elongate pivot member having a proximate end portion a central portion, and a distal end portion;    a pivot member float mounted on said distal end portion of said elongate pivot member;    said pivot member having a pivot point in said central portion;    a pivot axle;    said pivot adjustment upright member supporting said pivot axle;    said pivot axle pivotally supporting said elongate pivot member at said pivot point; and    a connecting cord secured to said proximate end portion of said elongate pivot member, said connecting cord being directly connected to the flap member of a flap valve of the toilet; 
 whereby, upon said float rising upward with water approaching an overflow condition, said elongate pivot member rotates around said pivot, pulling said proximate end of said pivot member downward, and thereby pulling said connecting cord, said connecting cord pulling the flap element downward against the seat of the flap valve of the water tank, thereby stopping flow of water from the toilet tank to the toilet bowl and avoiding overflow of the bowl.  
   
   
   
       2 . The toilet overflow check system according to  claim 1 , wherein said pivot adjustment upright member includes means defining a plurality of pivot points for selective placement of said pivot axle, whereby said pivot member is vertically adjustable, whereby the overflow check system is adjusted to be even with a predetermined, ordinary water level in said toilet bowl.  
   
   
       3 . The toilet overflow check system according to  claim 1 , wherein said elongate pivot member proximate end portion includes means defining a plurality of eyelets therealong and therethrough, for selective attachment of said connecting cord thereto.  
   
   
       4 . The toilet overflow check system according to  claim 1 , wherein said pivot adjustment upright member includes an upper horizontal member extending across a toilet bowl rim, and an outer, depending portion thus to mount said pivot adjustment upright member firmly onto the annular rim of a toilet bowl.  
   
   
       5 . The toilet overflow check system according to  claim 4 , wherein said outer depending portion includes a thumbscrew for securing said depending portion firmly to the annular rim of a toilet bowl.  
   
   
       6 . The toilet overflow check system according to  claim 4 , wherein said pivot adjustment upright member, said upper horizontal member, and said outer depending portion are of one-piece, unitary construction.  
   
   
       7 . A toilet overflow check system for use with a toilet having a bowl with an annular, upper rim, a water tank, and a flapper valve assembly at the bottom of the tank for admitting water into the toilet bowl, the flapper valve assembly including a flapper valve and a valve seat therefor, said overflow check system comprising: 
 an upright member depending into the toilet bowl from the rim of the toilet bowl;    an elongate pivot member pivotally attached to said upright member and having a distal end and a proximate end nearer the flapper valve;    a cord connecting the pivot member proximate end with the flapper valve; and    a float on the pivot member distal end;    whereupon rising of water within the toilet bowl above a predetermined level will cause said pivot member to rotate under urging from said float, to pull said cord and pull the flapper valve down against its seat, thus stopping water flow from the toilet tank into the toilet bowl.    
   
   
       8 . The overflow check system according to  claim 7 , wherein said upright member includes bracket structure for releasably mounting said upright member firmly on the annular rim of a toilet.  
   
   
       9 . The overflow check system according to  claim 7 , said upright member including multiple mounting points vertically therealong for selective mounting of said pivot member.  
   
   
       10 . The overflow check system according to  claim 7 , wherein said pivot member proximate end includes a plurality of attachment holes formed therethrough for selective attachment of said cord.  
   
   
       11 . The overflow check system according to  claim 7 , there further being a screw eye attachment in the flapper valve of the toilet for attachment of the cord thereto.
