Multi-directional brush

Abstract

A multi-directional brush includes a handle, a brush, and an angle adjuster that pivotally connects the brush to the handle. The adjuster includes a lower half portion and a upper half portion. The upper half portion includes a base and an elongate column protruded from the base, which are received in a mounting hole in the brush. The base has a shape of semi-sphere, and the elongate column has a circular shape. A blocking piece prevents rotation of the brush body with respect to the angle adjuster. The blocking piece is fastened to the angle adjuster by a fastening device.

1 . A multi-directional brush comprising:

       2 . The multi-directional brush of  claim 1 , wherein the upper half portion is adapted to engage with the lower portion at a plurality of angles between the centerline of the upper half portion and the centerline of the lower half portion.  
   
   
       3 . The multi-directional brush of  claim 1 , wherein the base has a shape of semi-sphere.  
   
   
       4 . The multi-directional brush of  claim 3 , wherein the elongate column has a circular shape.  
   
   
       5 . The multi-directional brush of  claim 4 , wherein the mounting hole has a shape corresponding to the base and the elongate column whereby tight fit between the upper half portion and the brush body is provided.  
   
   
       6 . The multi-directional brush of  claim 5 , wherein the upper half portion further comprises a securing device that secures the upper half portion to the brush body.  
   
   
       7 . The multi-directional brush of  claim 6 , wherein the securing device comprises one or more spring washer fixed to the end of the elongate column, wherein the spring washer comprises a plurality of teeth that is adapted to cut into the wall of the mounting hole.  
   
   
       8 . The multi-directional brush of  claim 5 , wherein the upper half portion is adapted to engage with the lower portion at a plurality of angles between the centerline of the upper half portion and the centerline of the lower half portion.  
   
   
       9 . The multi-directional brush of  claim 1 , wherein the upper half portion further comprises an upper engaging body, wherein the lower half portion comprises a lower engaging body, wherein the upper engaging body comprises a plurality of radial teeth, wherein the lower engaging body comprises a plurality of radial teeth, wherein the upper engaging body is pivotable with respect to the lower engaging body, wherein the teeth of the upper engaging body engage with the teeth of the lower engaging body.  
   
   
       10 . The multi-directional brush of  claim 9 , wherein the angle adjuster further comprises a fastening device that fastens the lower half portion and the upper half portion.  
   
   
       11 . The multi-directional brush of  claim 1 , further comprising a blocking piece that prevents rotation of the brush body with respect to the angle adjuster.  
   
   
       12 . The multi-directional brush of  claim 11 , wherein the blocking piece is fastened to the angle adjuster by a fastening device.  
   
   
       13 . The multi-directional brush of  claim 12 , wherein the blocking piece comprises a blocking piece body and a tab that extends from the blocking piece body, wherein the blocking piece body is attached to the upper half portion of the angle adjuster, wherein the tab partly covers the brush body.  
   
   
       14 . The multi-directional brush of  claim 13 , wherein the blocking piece body comprises a hole, and the upper half portion comprises a boss that is received by the hole of the blocking piece body, wherein the boss comprises a tapered portion, wherein the diameter of the tapered portion decreases toward the free end of the boss, wherein the hole has a step that engages with the tapered portion of the boss whereby the blocking piece does not fall out of the boss.  
   
   
       15 . The multi-directional brush of  claim 14 , wherein the tapered portion of the boss comprises one or more recesses around the periphery thereof.  
   
   
       16 . The multi-directional brush of  claim 15 , wherein the base has a shape of semi-sphere, wherein the elongate column has a circular shape, wherein the mounting hole has a shape corresponding to the base and the elongate column whereby tight fit between the upper half portion and the brush body is provided.  
   
   
       17 . The multi-directional brush of  claim 16 , wherein the upper half portion further comprises a securing device that secures the upper half portion to the brush body, wherein the securing device comprises one or more spring washer fixed to the end of the elongate column, wherein the spring washer comprises a plurality of teeth that cut into the wall of the mounting hole.  
   
   
       18 . The multi-directional brush of  claim 17 , wherein the upper half portion is adapted to engage with the lower portion at a plurality of angles between the centerline of the upper half portion and the centerline of the lower half portion.  
   
   
       19 . The multi-directional brush of  claim 17 , wherein the lower half portion is integrated with the handle at the second handle end.
