Extruded box concrete float blade

Abstract

An implement for working uncured concrete includes a removable manipulator and a tool for engaging the surface of uncured concrete. The implement is configured to permit manipulators to be interchanged such that the appropriate manipulate or may be used to perform a particular task during the concrete curing process.

1 . An implement for working the surface of uncured concrete comprising
 a manipulator configured to permit a user to manually move the implement over the surface of the incurred concrete,   a tool having a concrete engaging surface, the tool including a plurality of elongate channels, the channels being separated by at least one relatively thin wall that extends from a lower wall to an upper wall, and   a quick release support structure secured to the tool, the manipulator being releasably secured to the quick release support structure.   
     
     
         2 . The implement of  claim 1 , wherein the manipulator comprises a handle having a shaft, a collar supported on the shaft and slidable relative to the shaft, a pair of struts pivotably coupled to the collar at a first end of each of the struts, a bracket, each of the struts pivotably coupled to the bracket at a second end of each strut, the bracket being releasably secured to the quick release support structure. 
     
     
         3 . The implement of  claim 2 , wherein the quick release support structure comprises a pair of spaced apart supports, each supports extending upwardly from a top surface of the tool. 
     
     
         4 . The implement of  claim 3 , wherein the quick release support structure comprises a manually manipulable clamp screw engaged with each support of the quick release support structure, the bracket being clamped to each of the supports by respective manually manipulable clamp screw. 
     
     
         5 . The implement of  claim 4 , wherein the bracket includes respective notches that overlie the shaft of the respective clamp screws to secure the bracket from lateral movement relative to the he supports. 
     
     
         6 . The implement of  claim 5 , wherein the tool comprises at least three channels that extend along the length of the tool, wherein the tool includes at least two outboard channels, each outboard channel having a first sidewall extending upwardly from the lower wall and defining an edge of the tool, and each outboard channel being defined by an inner wall that extends from the lower wall to the upper wall, the inner wall being color than the first sidewall, and each outboard channel being defined by an incline wall that extends from the first sidewall to the inner wall of each respective chamber. 
     
     
         7 . The implement of  claim 6 , wherein each support of the quick release support structure is secured to the tool by a fastener that extends through the upper wall of the tool and into a channel of the tool. 
     
     
         8 . The implement of  claim 7 , wherein the fastener that secures the support of the quick release support structure extends through a spacer and threads into a plate positioned in the channel. 
     
     
         9 . The implement of  claim 3 , wherein each support of the quick release support structure is secured to the tool by a fastener that extends through the upper wall of the tool and into a channel of the tool. 
     
     
         10 . The implement of  claim 9 , wherein the fastener that secures the support of the quick release support structure extends through a spacer and threads into a plate positioned in the channel. 
     
     
         11 . The implement of  claim 10 , wherein the implement further comprises a vibrator unit configured to transfer vibration to the tool. 
     
     
         12 . The implement of  claim 11 , wherein the vibrator unit is configured to be supported by the supports of the quick release support structure. 
     
     
         13 . The implement of  claim 12 , wherein a manually manipulable clamp screw simultaneously secures the bracket and the vibrator unit to a support of the quick release support structure. 
     
     
         14 . The implement of  claim 13 , wherein the vibrator unit comprises a frictional throttle. 
     
     
         15 . The implement of  claim 14 , wherein the manipulator comprises a handle that is independent from the vibrator unit, the orientation of the handle relative to the tool being adjustable independent of the vibrator unit. 
     
     
         16 . The implement of  claim 15 , wherein the struts move with the handle as it is adjusted. 
     
     
         17 . The implement of  claim 1 , wherein the implement further comprises a vibrator unit configured to transfer vibration to the tool. 
     
     
         18 . The implement of  claim 14 , wherein the manipulator comprises a handle that is independent from the vibrator unit, the orientation of the handle relative to the tool being adjustable independent of the vibrator unit. 
     
     
         19 . The implement of  claim 18 , wherein the quick release support structure comprises a pair of spaced apart supports, each supports extending upwardly from a top surface of the tool. 
     
     
         20 . The implement of  claim 19 , wherein the vibrator unit is configured to be supported by the supports of the quick release support structure, and wherein a manually manipulable clamp screw simultaneously secures the bracket and the vibrator unit to a support of the quick release support structure.
