Abstract:
An exercise device which comprises:a first arm having first end and a second end; a second arm having a first end and a second end; a joint assembly defining an axis of rotation, said first end of said first arm being attached to said joint assembly to establish a fixed relationship between said first arm and said axis, with said first end of said second arm being pivotally attached to said joint assembly for rotation of said second arm about said axis in a first direction and in a second direction; a means attached to said second end of said first arm for stabilization of said second end of said first arm during a movement of said second arm about said axis of rotation; a shaft mounted on said joint assembly and fixedly interconnected with said second arm; a one-way clutch engageable with said shaft; a cone member engaged with said one-way clutch for free rotation of said second arm relative to said cone member around said axis in said second direction, and for rotation of said second arm with said cone member around said axis in said first direction, said cone member having a surface; a cup member fixedly attached to said first arm, said cup member having a surface dimensioned for a mating engagement with said surface of said cone member at an interface there between to establish said resistance to said rotation of said second arm, and wherein said cup member is formed with an annular groove, said groove being centered on said axis of rotation and lying in a plane substantially perpendicular thereto; a guide pin, said guide pin being mounted on said second arm for insertion into said groove to interconnect said second arm with said joint assembly; a plunger; a force transfer mechanism positioned between said plunger and said cone member; a knob mounted on said cup member and connected to said plunger, said knob being rotatable to selectively move said plunger relative to said cone member to activate said force transfer mechanism and urge said surface of said cone member against said surface of said cup member to establish said resistance; and a plurality of spring-loaded detents, said spring-loaded detents being mounted on said cup member to urge against said knob to provide an aural signal in response to rotation of said knob.
