Wrist exerciser

Claim 1

A wrist exercising device for suspending between the hands of a user comprising: an elongated flexible member for supporting a load; a reel having a peripheral surface onto which said flexible member is windable through a plurality of turns, said reel having a pair of opposed ends; a pair of generally cylindrical handles respectively disposed on said ends of said reel, said handles having a common axis defining the axis of rotation of said device, rotation of said handles about said axis serving to rotate said reel and wind said flexible member on said peripheral surface to raise said weight, the improvement wherein said peripheral surface is eccentric in relation to said common axis, having a first portion of minimum eccentricity and a second portion of maximum eccentricity diametrically opposed thereto, with portions of said surface intermediate said first and second portions having intermediate eccentricity, whereby the effort necessary to raise said load varies with the rotation of said handles about their common axis to pass through either a maximum or a minimum value for any 180° interval of rotation and wherein said reel has a central axis of rotational symmetry parallel to said common axis and offset therefrom.
