Work Tool Indicator for a Machine

Abstract

A coupler unit for coupling a work tool to a machine. The coupler unit comprising an indicator coupled to the coupler unit and pivotable between a first position and a second position. The second position indicative of the work tool coupled to the machine. A coupling member movable by an actuator to couple the work tool to the machine wherein coupling of the work tool by the coupling member causes the indicator to pivot from the first position to the second position.

1 . A coupler unit for coupling a work tool to a machine, the coupler unit comprising:
 an indicator coupled to the coupler unit and pivotable between a first position and a second position, wherein the second position is indicative of the work tool being coupled to the machine;   a coupling member movable by an actuator to couple the work tool to the machine;   wherein coupling of the work tool by the coupling member is configured to cause the indicator to pivot from the first position to the second position.   
     
     
         2 . The coupler unit of  claim 1 , wherein the indicator is coupled to a coupler arm of the coupler unit. 
     
     
         3 . The coupler unit of  claim 1 , wherein the indicator is configured to provide a visual indication of an engagement status of the work tool with the machine, the first position of the indicator being indicative of a disengagement and the second position being indicative of an engagement between the work tool and the machine. 
     
     
         4 . The coupler unit of  claim 1 , further comprising a spring configured to bias the indicator towards the first position. 
     
     
         5 . The coupler unit of  claim 1 , wherein the coupling member has at least one engagement pin configured to couple the work tool to the machine. 
     
     
         6 . The coupler unit of  claim 1 , wherein the coupling member is configured to actuate the indicator to the second position after coupling with the work tool. 
     
     
         7 . The coupler unit of  claim 1 , further comprising a cover for the indicator. 
     
     
         8 . A machine having a coupler unit, the coupler unit comprising:
 an indicator coupled to the coupler unit and pivotable between a first position and a second position, wherein the second position is indicative of the work tool being coupled to the machine;   a coupling member movable by an actuator to couple the work tool to the machine;   wherein coupling of the work tool by the coupling member causes the indicator to pivot from the first position to the second position.   
     
     
         9 . The machine of  claim 8 , wherein the indicator is coupled to a coupler arm of the coupler unit. 
     
     
         10 . The machine of  claim 8 , wherein the indicator is configured to provide a visual indication of an engagement status of the work tool with the machine, the first position of the indicator being indicative of a disengagement and the second position being indicative of an engagement between the work tool and the machine. 
     
     
         11 . The machine of  claim 8 , further comprising a spring configured to bias the indicator towards the first position. 
     
     
         12 . The machine of  claim 8 , wherein the coupling member has at least one engagement pin configured to couple the work tool to the machine. 
     
     
         13 . The machine of  claim 8 , wherein the coupling member is configured to actuate the indicator to the second position after coupling with the work tool. 
     
     
         14 . The machine of  claim 8 , further comprising a cover for the indicator. 
     
     
         15 . A method of coupling a work tool to a machine, the machine comprising:
 a coupling member for coupling the work tool to the machine;   an indicator coupled to the machine and movable between a first position and a second position, the second position indicative of the work tool coupled to the machine; the method comprising:   moving the coupling member to couple the work tool;   wherein coupling of the work tool by the coupling member moves the indicator to the second position.   
     
     
         16 . The method as claimed in  claim 15 , wherein the indicator is coupled on a coupler arm of the machine. 
     
     
         17 . The method as claimed in  claim 15 , wherein the indicator provides a visual indication of an engagement status of the work tool with the machine, the first position of the indicator being indicative of a disengagement and the second position being indicative of an engagement between the work tool and the machine. 
     
     
         18 . The method as claimed in  claim 15 , the method further comprising providing a spring coupled to the indicator to bias the indicator towards the first position. 
     
     
         19 . The method as claimed in  claim 15 , wherein the coupling member moves the indicator to the second position after coupling with the work tool. 
     
     
         20 . The method as claimed in  claim 15  further comprising providing a cover for the indicator.
