Anti-slip scrubber brush and assembly methods

Abstract

In one aspect, a scrubber brush assembly is provided. The scrubber brush assembly includes a scrubber brush including exterior molded surfaces and a mounting passage having interior molded surfaces, the interior molded surfaces having molded foam, raised rotation-restraining features, and a mandrel including recesses directly coupled to the molded foam, raised rotation-restraining features of the scrubber brush to prevent slippage. Scrubber brushes and methods of assembly are provided, as are numerous other aspects.

The invention claimed is: 
     
         1 . A method of assembling a scrubber brush assembly, comprising:
 providing a scrubber brush having a scrubber brush body with a mounting passage having a molded interior surface with molded foam, raised rotation-restraining features; and   inserting a mandrel into the mounting passage and receiving the molded foam, raised rotation-restraining features in contact with recesses formed on an outer surface of the mandrel to form the scrubber brush assembly.   
     
     
         2 . The method of  claim 1 , wherein the receiving of the molded foam, raised rotation-restraining features in contact with the recesses comprises substantially filling the recesses with the molded foam, raised rotation-restraining features. 
     
     
         3 . The method of  claim 2 , further comprising:
 engaging the foam molded, raised rotation-restraining features into the recesses along substantially an entire length L of the scrubber brush.   
     
     
         4 . The method of  claim 1 , further comprising:
 providing openings on the mandrel, the openings being configured and adapted to jet a liquid directly into the scrubber brush.   
     
     
         5 . A scrubber brush assembly, comprising:
 a scrubber brush having a scrubber brush body including a mounting passage with molded interior surfaces, the molded interior surfaces having molded foam, raised rotation-restraining features; and   a mandrel having recesses formed on an outer surface of the mandrel, the mandrel being directly coupled to the molded interior surfaces by receiving the molded foam, raised rotation-restraining features in direct contact with the recesses.   
     
     
         6 . The scrubber brush assembly of  claim 5 , wherein the molded foam, raised rotation-restraining features comprise a plurality of molded foam ribs that extend longitudinally along substantially an entire length of the scrubber brush. 
     
     
         7 . The scrubber brush assembly of  claim 6 , wherein the molded foam, raised rotation-restraining features comprise four or more molded foam ribs. 
     
     
         8 . The scrubber brush assembly of  claim 5 , wherein the molded foam, raised rotation-restraining features comprise open-cell foam. 
     
     
         9 . The scrubber brush assembly of  claim 5 , wherein each of the molded foam, raised rotation-restraining features comprises at least two sides in direct contact with at least two sides of the recesses. 
     
     
         10 . The scrubber brush assembly of  claim 5 , wherein the molded interior surfaces further comprise molded foam grooves. 
     
     
         11 . The scrubber brush assembly of  claim 10 , wherein each of the molded foam grooves comprise a radiused bottom profile. 
     
     
         12 . The scrubber brush assembly of  claim 10 , wherein the molded foam grooves extend longitudinally along substantially an entire length of the scrubber brush. 
     
     
         13 . The scrubber brush assembly of  claim 5 , wherein the molded raised rotation-restraining features have a height of greater than about 1.5 mm. 
     
     
         14 . The scrubber brush assembly of  claim 5 , wherein a top side of the molded raised rotation-restraining features has a width of greater than about 4 mm. 
     
     
         15 . A scrubber brush, comprising:
 a scrubber brush body having a mounting passage with a molded interior surface with molded foam, raised rotation-restraining features configured and adapted to couple into recesses on an outer surface of a mandrel.   
     
     
         16 . The scrubber brush of  claim 15 , wherein the molded foam, raised rotation-restraining features comprise a plurality of molded ribs that extend longitudinally along substantially an entire length of the scrubber brush. 
     
     
         17 . The scrubber brush of  claim 15 , wherein the molded foam, raised rotation-restraining features comprise open-cell foam. 
     
     
         18 . The scrubber brush of  claim 15 , wherein the molded foam, raised rotation-restraining features have a height of greater than about 1.5 mm, and a width of greater than about 4 mm. 
     
     
         19 . The scrubber brush of  claim 15 , wherein the scrubber brush body comprises open-cell foam. 
     
     
         20 . The scrubber brush of  claim 19 , wherein the interior molded surface comprises molded foam grooves.
