Cleaning brush

Abstract

A brush for cleaning purposes comprising a brush head from which a plurality of bristles arranged in clumps depend from an underside thereof, the clumps of bristles being disposed in at least two groups, a first group in which the clumps of bristles exhibit a variation in orientation from a direction which is substantially perpendicular to the surface to be cleaned in normal use of the brush to being inclined in a first direction relative to the perpendicular direction, and a second group in which the clumps of bristles exhibit a variation in orientation from substantially perpendicular to being inclined to the perpendicular in a direction opposite to said first direction.

1 . A brush for cleaning purposes comprising a brush head from which a plurality of bristles arranged in clumps depend from an underside thereof, the clumps of bristles being disposed in at least two groups, a first group in which the clumps of bristles exhibit a variation in orientation from a direction which is substantially perpendicular to the surface to be cleaned in normal use of the brush to being inclined in a first direction relative to the perpendicular direction, and a second group in which the clumps of bristles exhibit a variation in orientation from substantially perpendicular to being inclined to the perpendicular in a direction opposite to said first direction.  
   
   
       2 . A brush according to  claim 1  wherein the brush head has a forward end and rear end from which a handle extends, the bristles of the first group extending more forwardly relative to the forward end than those of the second group and at this end being inclined in the forward direction, the bristles of the second group extending more rearwardly relative to the rear end than those of the first group and at this end being inclined in the rearward direction.  
   
   
       3 . A brush according to  claim 2  wherein the clumps of bristles of the first group become progressively move inclined towards the front end of the head.  
   
   
       4 . A brush according to  claim 2  wherein the clumps bristles of the second group become progressively move inclined towards the rear end of the head.  
   
   
       5 . A brush according to  claim 2  wherein the second group of bristle clumps are arranged along the longitudinal centre the brush head and the clumps of the first group at least partly surround the second group in a horseshoe shape.  
   
   
       6 . A brush according to  claim 5  wherein the most rearward clumps of the second group extend through the open side of the horseshoe shape of the first group of clumps.  
   
   
       7 . A brush according to  claim 1  wherein an upper region of the brush head may be provided with additional clumps of bristles at a forward end thereof.  
   
   
       8 . A brush according to  claim 1  wherein the underside of the brush head is downwardly convex in a lateral direction perpendicular to a direction between the forward and rear ends.  
   
   
       9 . A brush according to  claim 1  wherein the underside of the brush head is downwardly convex in the direction between the forward and rear ends.  
   
   
       10 . A brush according to  claim 1  wherein the brush head is of elongate form in the direction between forward and rear ends.  
   
   
       11 . A brush according to  claim 1  wherein an upper region of the brush head is provided with a scraping lip at a forward end thereof.
