Abstract: An articulatable mounting device for positioning a hand grip or a tool interface in a particular position, is described. The articulatable positioning device comprises a mounting means having variously sized curved surfaces for contacting a plurality of different sized tubing in an area contact relationship. The articulatable mounting device also comprises two pairs of mating serrated surfaces that provide a wide range of articulatable motion for the hand grip or tool interface with respect to the mounting means and the associated tubular support. A slotted connection between the pair of serrated surface further increases the range motion.
