Isokinetic paintbrush control handle

Abstract

The isokinetic result of forces upon the human muscles of the forearm, wrist and hand from the forces encountered by the tasks of thrust, draw and twist during applying coating materials to substrates (commonly called “painting”) are reduced by the inclusion of sections of the embodiment, tapered to oppose the direction(s) of said task forces, in sufficient length and shape to engage both hands to eliminate repeated gripping strains on the muscles of each hand, wrist and forearm. Non-obvious embodiments include a plurality of tapering shapes formed into the shafts of the brush tool to prevent slipping and loss of control with less strain of muscles required for gripping with two-hand paint brushes. Non-obvious embodiments include a plurality of tapering shapes formed into the shafts of the brush tool to prevent slipping and loss of control with less strain of muscles required for gripping with one-hand brushes.

1 . A paintbrush containing a plurality of bristles at the distal end thereof and a shaft handle with a plurality of ribs tapering with larger dimension towards the proximal end.  
   
   
       2 . Non-obvious variations of these embodiments include hang holes at selected locations along the shaft.  
   
   
       3 . Non-obvious variation embodiments are like the preferred embodiments with means of detaching the common bristle plurality.  
   
   
       4 . Non-obvious variation embodiments are like the preferred embodiments with means of a second section of a plurality of ribs tapering with larger dimension towards the distal end, thus one section in direction of thrust and the opposing section in direction of draw motions of the user.  
   
   
       5 . Non-obvious variation embodiments are like the preferred embodiments with shortened length to allow operation of one-hand only.
