Dual flush handle control

Abstract

Disclosed are various embodiments for a dual flush handle control. A rotary handle assembly for a dual flush toilet system includes a flush stop, a handle lever, a handle switch, and a restriction arm. The handle switch is configured to extend through a surface of the handle lever from an unextended position to an extended position. The restriction arm is configured to engage the handle switch at a proximal end and control engagement with the flush stop to restrict rotation of the handle lever based upon the position of the handle switch.

         5 . The rotary handle assembly of  claim 1 , wherein the surface of the handle lever is contoured. 
     
     
         6 . The rotary handle assembly of  claim 5 , wherein the contoured surface of the handle lever includes at least one depression, wherein the handle switch extends through the surface of the handle lever in the at least one depression. 
     
     
         7 . A rotary handle assembly for a dual flush toilet system, comprising:
 a mounting sleeve including a flush stop;   a handle lever including a shaft passing through the mounting sleeve;   a handle switch configured to extend through a surface of the handle lever from an unextended position to an extended position; and   a restriction arm configured to engage the handle switch at a proximal end and the flush stop at a distal end to restrict rotation of the handle lever.   
     
     
         8 . The rotary handle assembly of  claim 7 , wherein the rotary handle assembly is configured to restrict rotation of the handle lever to a first position when the handle switch is held in the unextended position and to restrict rotation of the handle lever to a second position otherwise. 
     
     
         9 . The rotary handle assembly of  claim 8 , wherein a quick flush of the dual flush toilet system is initiated when rotation of the handle lever is restricted to the first position and a full flush of the dual flush toilet system is initiated when rotation of the handle assembly is restricted to the second position. 
     
     
         10 . The rotary handle assembly of  claim 7 , wherein the rotary handle assembly is configured to detachably connect to an actuation control box of the dual flush toilet system, the actuation control box configured to translate a rotational motion of the handle lever to initiate a flush mode of the dual flush toilet system. 
     
     
         11 . The rotary handle assembly of  claim 7 , wherein the handle lever further includes a pin, the restriction arm configured to pivot about the pin during rotation of the handle lever. 
     
     
         12 . The rotary handle assembly of  claim 7 , further comprising a spring mechanism configured to retract the handle switch into the handle lever from the extended position to the unextended position. 
     
     
         13 . The rotary handle assembly of  claim 7 , wherein the rotary handle assembly is configured to restrict rotation of the handle lever to a first position when the handle switch is in the extended position and to restrict rotation of the handle lever to a second position otherwise. 
     
     
         14 . A dual flush toilet system, comprising:
 a dual flush assembly;   an activation control box in communication with the dual flush assembly; and   a rotary handle assembly detachably connected to the activation control box, the rotary handle assembly including:
 a handle lever that initiates a quick flush of the dual flush assembly when rotated to a first position and a full flush of the dual flush assembly when rotated past the first position to a second position; and 
 a handle switch configured to engage a restriction arm to restrict rotation of the handle lever to the first position when handle switch is depressed and to restrict rotation of the handle lever to the second position otherwise. 
   
     
     
         15 . The dual flush toilet system of  claim 14 , wherein the restriction arm engages the handle switch at a proximal end and a flush stop at a distal end to restrict rotation of the handle lever. 
     
     
         16 . The dual flush toilet system of  claim 15 , wherein the handle lever further includes a pin, the restriction arm configured to pivot about the pin during rotation of the handle lever. 
     
     
         17 . The dual flush toilet system of  claim 15 , wherein the rotary handle assembly further comprises a mounting sleeve including the flush stop, where the handle lever includes a shaft passing through the mounting sleeve, the shaft in communication with the activation control box. 
     
     
         18 . The dual flush toilet system of  claim 14 , further comprising a spring configured to restore the handle lever to a neutral position from the first and second positions. 
     
     
         19 . The dual flush toilet system of  claim 14 , wherein the handle switch extends from the handle lever when the handle lever is rotated from the first position to the second position.
