Adjustable link mechanism for tank of toilets

Abstract

An angle adjustable link mechanism for toilets includes a flush handle connected to the tank and a connection extension extends from a shaft of the flush handle. An adjustable assembly includes a first part and a second part which is rotatably connected to the first part. The connection extension is connected to the second part. A link has an end connected to the first part which is pivoted about a common axis with the second part so that the position of the link is set relative to the flush handle by adjustment between the first and second parts.

1 . A link mechanism for toilets, comprising:
 a flush handle with a connection extension extending from a shaft thereof;   an adjustable assembly having a first part and a second part which is rotatably connected to the first part, the first part including a first connection member and a first pivotable member which is connected to a side of the first connection member, the first connection member including a first slot, the second part including a second connection member and a second pivotable member which is connected to a side of the second connection member, the second connection member including a second slot in which the connection extension is fixed therewith, the first connection member including a rack portion integrally formed on the side where the first pivotable member is connected, the rack portion being formed axially in the side of the first connection member and the first pivotable member located beneath the rack portion, the second pivotable member being a cylindrical member and including teeth integrally defined in an outer periphery thereof so as to be directly engaged with the rack portion, the first and second pivotable members rotatably sharing a common axle, and   a link having a first end which is connected to the first slot in the first part.   
   
   
       2 . The mechanism as claimed in  claim 1 , wherein a collar is mounted on a top of the second pivotable member and the common axle extends through the collar, the second pivotable member and the first pivotable member and is connected with a nut, a tongue extends radially from the collar and a stud extends from an underside of the tongue, the stud is inserted in a recess defined in a top of the first connection member. 
   
   
       3 . The mechanism as claimed in  claim 1 , wherein a positioning member extends through a hole defined in the first connection member and is connected with a hole in the link in the first slot. 
   
   
       4 . The mechanism as claimed in  claim 1 , wherein a positioning member extends through a hole defined in the second connection member and contacts against the connection extension in the second slot. 
   
   
       5 . The mechanism as claimed in  claim 1 , wherein the first pivotable member includes teeth defined in a top thereof and the second pivotable member includes teeth defined in a bottom thereof, the teeth the first pivotable member are engaged with the teeth the second pivotable member. 
   
   
       6 . The mechanism as claimed in  claim 1 , wherein the link includes a first section and a second section which is parallel to the first section, the first and second sections are located on two different parallel planes, a connection section is connected between the first and second sections at an angle.
