Adjustable angle cleaning brush head

Abstract

Adjustable angle cleaning brush comprised of a handle and rotatably attached first longitudinal brush head and a second longitudinal brush head that are side by side and parallel to each other in one configuration and rotate out to a T position with respect to the handle in a second configuration. One end of each brush head is fixedly attached to a pinion gear within the handle. The pinion gears engage a centrally located rack so that when a user pushes up on an actuation button attached to the rack, the brushes rotate out into a T position. They are held in a T position by a spring biased post. The user can press on the post to return the brush heads to the side by side position.

1 . adjustable angle cleaning brush head comprising:
 a first brush head;   a second brush head;   a brush angle change button;   a hollow main handle;
 a slide button; 
   a slide button track;   a locking post;
 a locking post spring 
   a rack tension spring;   a first pinion gear;   a second pinion gear;   a rack; and   a rack extension shaft;
 said hollow handle enclosing said rack and said rack extension shaft and said tension spring which are all located longitudinally within said handle; 
 said hollow handle being widened at the uppermost portion to retain said first and second pinion gears; 
 said rack capable of extending out of the top portion of said handle; 
 said slide button fixedly attached to said rack extension shaft; 
 said tension spring attached at one end to said slide button and at the opposite end to a retaining post within the lower portion of said hollow handle; 
 said first pinion gear fixed by a shaft on the upper left side of said rack and said second pinion gear fixed by a shaft on the upper right side of said rack; 
 said first and second gear shafts rotatably attached to apertures in the said widened portion of said handle; 
 said first and second brush heads being constructed in a standard longitudinal bottle brush format; 
 said first brush head fixedly attached to said first pinion gear and said second brush head fixedly attached to said second pinion gear so that both said brush heads are in close proximity to and parallel to each other; 
 said first and second brush heads capable of rotating outwardly from each other to form a T shape with respect to said handle when a user slides said slide button along said slide button track located on said handle in an upward motion toward said brush head portion which causes said rack to move upward and force said first pinion gear to rotate counter clockwise and said second pinion gear to rotate clockwise; 
 said first and second brush heads capable of being fixed in place in said T position when said spring biased locking post engages an aperture in the side of said hollow handle; 
 said first and second brush heads capable of being disengaged from said T position and returning to said side by side parallel position when a user presses on the tip of said locking post so that it is freed from said side aperture thereby allowing said rack to be pulled downward. 
   
   
   
       2 . Adjustable angle cleaning brush head as claimed in  claim 1  wherein a third brush head is fixedly attached to the opposite end of said handle;
 said third brush head angled at approximately forty five degrees with respect to said handle.   said third brush bristles mounted in a standard rigid flat plastic base plate so that said third brush head bristles are facing away from said handle.   
   
   
       3 . An alternate embodiment of said adjustable angle cleaning brush head as claimed in  claim 1  wherein said cleaning brush head is comprised on only one rotatable brush head capable of forming an L shape rather than the said T shape. 
   
   
       4 . An alternate embodiment of said adjustable angle cleaning brush head as claimed in  claim 1  wherein said first and second brush heads are capable being fixed a plurality of Y shaped configurations by use of a plurality of said locking pin apertures located in a linear orientation on the side of said brush handle. 
   
   
       5 . An alternate embodiment of said adjustable angle cleaning brush head as claimed in  claim 1  wherein said first and second pinion gears are eliminated and said rack is eliminated and said first and second brush heads are rotatably pinned to the top most portion of a centrally located slidable post within said hollow handle and where said slidable post can be pulled down by the user causing said first and second brush heads to be forced from a parallel position to a T position with respect to said handle.
