Therapeutic body brush

Abstract

A body brush is provided for use in cleaning the human body, and includes two or more brush head mounting structures each fitted with a brush head. A brush head rotation mechanism is mounted to the brush housing and is drivably connected to two or more brush head mounting structures for rotating the brush heads, and a brush head axial reciprocation mechanism is mounted to the brush housing and is drivably connected to the at least two brush head mounting structures for axially reciprocating the brush heads.

1 . A body brush for us in cleaning the human body, comprising: 
 a brush housing;    at least two brush head mounting structures each fitted with a brush head;    brush head rotation means mounted to said brush housing and drivably connected to said at least two brush head mounting structures for rotating said brush heads;    and brush head axial reciprocation means mounted to said brush housing and drivably connected to said at least two brush head mounting structures for axially reciprocating said brush heads out of unison.    
   
   
       2 . The body brush of  claim 1 , wherein said brush housing comprises a handle portion.  
   
   
       3 . The body brush of  claim 1 , wherein at least one of said brush heads comprises a disk with a disk outward face, said disk outward face being fitted with a cluster of bristles.  
   
   
       4 . The body brush of  claim 1 , wherein said brush heads are removable from said brush head mounting structures and replaceable with other said brush heads.  
   
   
       5 . The body brush of  claim 1 , wherein each said brush head mounting structure comprises a brush drive shaft, said body brush additionally comprising a shaft rotation motor mounted to said brush housing and having a motor drive shaft.  
   
   
       6 . The body brush of  claim 5 , additionally comprising drive transmission means between said motor drive shaft and said brush drive shafts; 
 such that said shaft rotation motor rotatably drives all of said drive shafts.    
   
   
       7 . The body brush of  claim 6 , wherein said drive transmission means comprises a motor gear on said motor drive shaft and a brush gear of each said brush drive shaft which mesh with said motor gear.  
   
   
       8 . The body brush of  claim 6 , wherein additional said brush drive shafts fitted with brush heads are fitted with intermeshing gears such that all said brush drive shafts are driven by said shaft rotation motor.  
   
   
       9 . The body brush of  claim 7 , wherein said motor gear and said brush gears have sufficient thickness that they can slide axially relative to each other a distance sufficient to provide brush head reciprocation while remaining inter-meshed.  
   
   
       10 . The body brush of  claim 7 , wherein said brush drive shafts have brush drive shaft inward ends, and wherein said brush reciprocation means comprises: 
 a disk cam rotatably mounted relative to said housing and having a circumferential cam flange with a sinusoidal edge against which said brush drive shaft inward ends ride;    biasing means biasing each of said brush drive shafts inwardly against said cam flange;    and a disk cam motor drivably connected to said disk cam for rotating said disk cam and said cam flange relative to said drive shaft inward ends to cause said brush drive shafts to move inwardly and outwardly relative to said brush housing.    
   
   
       11 . The body brush of  claim 10 , wherein said shaft rotation and disk cam motors are powered by a battery mounted relative to said brush housing and connected to said battery by a circuit wire linked to a control switch with a switch actuator accessible outside said brush housing, said control switch controlling one of brush head rotation and brush head reciprocation.  
   
   
       12 . The body brush of  claim 11 , wherein said brush housing is hollow to contain said shaft rotation and disk cam motors and said drive transmission means.  
   
   
       13 . The body brush of  claim 12 , wherein said brush housing additionally contains said battery.  
   
   
       14 . The body brush of  claim 1 , wherein said handle portion comprises an elongate member having substantially parabolic longitudinal curve to permit better reach of a user back.  
   
   
       15 . The body brush of  claim 1 , wherein said handle portion comprises an elongate flexible member having substantially no elastic memory.
