Polishing brush system

Abstract

A brush assembly for a floor machine. The brush includes a base having a annular moat, and a plurality of cleaning element set within the annular moat and secured to the base. The moat may include a plurality of pocket sets for receiving and securing legs of associated cleaning elements.

1 . A brush assembly for a floor machine, comprising:
 a base having a top side attachable to a floor machine and a bottom side opposite the top side,   an annular moat recessed within the bottom side; and   a plurality of cleaning elements secured within the annular moat and extending from the bottom side of the base.   
     
     
         2 . The brush assembly according to  claim 1 , wherein the plurality of cleaning elements are secured within the annual moat via a curable material. 
     
     
         3 . The brush assembly according to  claim 1 , wherein the cleaning elements each include a base portion configured to attach the base and an abrasive portion. 
     
     
         4 . The brush assembly according to  claim 3 , wherein the abrasive portion is overmolded to a distal end of the base portion. 
     
     
         5 . The brush assembly according to  claim 1 , wherein the cleaning elements are oriented along an axis that is angled in relation to a radius of the base. 
     
     
         6 . The brush assembly according to  claim 1 , further comprising a plurality of pockets disposed within the annular moat, each pocket configured to receive a cleaning element of the plurality of cleaning elements. 
     
     
         7 . The brush assembly according to  claim 1 , further comprising a plurality of pocket sets disposed within the annular moat, wherein each pocket of a pocket set is configured to receive a portion of the cleaning element base. 
     
     
         8 . The brush assembly according to  claim 7 , wherein the base of the cleaning element comprises at least two spaced apart legs, wherein each pocket of a pocket set is configured to receive one of the two spaced apart legs. 
     
     
         9 . The brush assembly of  claim 7 , wherein each pocket set includes a pocket set axis that is offset at an angle from a radius of the base. 
     
     
         10 . The brush assembly according to  claim 1 , wherein each cleaning element extends from the bottom surface of the base at an angle between about 25 degrees to about 75 degrees. 
     
     
         11 . A method for manufacturing a brush assembly comprising:
 providing a base with an recessed annular moat;   providing a plurality of cleaning elements each including a base portion and abrasive portion;   positioning the base portion of each cleaning element of the plurality of cleaning elements within the annular moat;   flooding the annular moat with a curable material; and,   securing the plurality of cleaning elements to the base by curing the curable material.   
     
     
         12 . The method according to  claim 11 , wherein providing the plurality of cleaning elements comprising overmolding the abrasive portion on a distal end of the base portion. 
     
     
         13 . The method according to  claim 11 , wherein the recessed annular moat includes a plurality of spaced apart pockets; wherein positioning the base portion of each cleaning element comprising placement of the base of the cleaning element into an associated pocket. 
     
     
         14 . The method according to  claim 11 , wherein each cleaning element is positioned to extend from a bottom surface of the base at an angle of about 30 degrees to about 65 degrees. 
     
     
         15 . The method according to  claim 11 , wherein each of the cleaning elements are clocked along an axis that is angled in relation to a radius of the base.
