Selectively attached and oriented indicator of body position and movement

Abstract

A pointer rod may be selectively positioned on a person or apparatus held and swung by a person and selectively positioned and oriented to provide a visible magnified indication of the motion of position at which the pointer rod is positioned.

What is claimed is: 
     
         1 . A body position and rotation indicator comprising:
 a pointer rod;
 the pointer rod extending from a base end to an indicating end opposite the base end; 
   a rod base;
 the base end of the pointer rod is rotationally connected to the rod base to rotate about an axis that extends through the pointer base; 
 the rod base forming a generally flat rod base support face that is generally parallel to the axis; 
   a pointer base
 the pointer base forming a generally flat pointer base support face 
 the rod base support face being sized to be selectively positionable against the pointer base support face; and 
 the pointer base and the rod base constructed for the rod base support face and the pointer base support face to be releasably secured to each other. 
   
     
     
         2 . The body position and rotation indicator of  claim 1  wherein:
 the rod base forms an edge adjacent to the pointer rod; 
 the edge positioned and configured to be adjacent to the pointer rod as the pointer rod rotates about the axis; 
 a series of pointer rod indicia marks is positioned along the edge; and 
 a rod mark is positioned on the pointer rod adjacent to the edge 
 whereby the pointer rod may be rotated about the axis to selectively position the angle of the pointer rod with respect to the rod base by reference to the rod mark and the series of pointer rod indicia marks. 
 
     
     
         3 . The body position and rotation indicator of  claim 1  further comprising a selectively actuated clamp for maintaining the pointer rod at a selected angle with respect to the rod base. 
     
     
         4 . The body position and rotation indicator of  claim 1  wherein:
 an outer periphery extends around the rod base support face; 
 a series of pointer base indicia marks is positioned adjacent to the outer periphery of the rod base support face; and 
 a pointer base mark is positioned on the pointer base adjacent to the pointer base support face 
 whereby the rod base may be rotated on the pointer base support face to selectively position the angle of the rod base with respect to the pointer base by reference to the pointer base mark and the series of pointer base indicia marks. 
 
     
     
         5 . The body position and rotation indicator of  claim 1  wherein the rod base comprises a ferromagnetic material adjacent to rod base support face and the pointer base further comprises a magnet that forms the pointer base support face whereby is releasably secured to the pointer base by attraction of the rod base to the magnet of the pointer base. 
     
     
         6 . A body position and rotation indicator comprising:
 a pointer rod;
 the pointer rod extending from a mounting end to an indicating end opposite the mounting end; 
   a pointer base;
 the mounting end of the pointer rod is connected to the pointer base by a joint that allows to rotate in two planes with respect to the pointer base; 
 the mounting end of the pointer rod is connected to the pointer base by a clamp that engages the mounting end of the pointer rod to the pointer base to prevent rotation and releases to allow the mounting end of the pointer rod to rotate with respect to the pointer base. 
   
     
     
         7 . The body position and rotation indicator of  claim 6  wherein a strap extends through the pointer base to secure the pointer base to a desired location on a person's body.
