Abstract:
1. An exerciser comprising: a frame constructed and arranged to be mounted stably on a horizontal surface; left and right elongated foot pedaling members each including a forward end and rearward end and a foot receiving structure between said rearward and forward ends; a crank assembly mounted on said frame for rotation about a generally horizontal axis; said crank assembly including a left crank rotatably connected to one end of said left foot pedaling member and a diametrically opposed right crank rigidly fixed with respect to said left crank and rotatably connected to one end of said right foot pedaling member; left and right arms each pivoted at one end thereof to said frame and having a free end spaced from the one end thereof; left and right springs each connected between said frame and an associated left or right arm constructed and arranged to resiliently bias the free end of the associated left or right arm upwardly into a limiting position and to allow resilient downward movement of the associated left or right arm away from said limiting position; left and right rollers rotatably mounted on the free ends of said left and right arms, respectively, constructed and arranged to rollingly engage opposite end portions of said left and right foot pedaling members, respectively, so that the foot engaging structures of said left and right foot pedaling members move in a substantially elliptical path as the user moves the left and right foot pedaling members through 180° out of phase cycles each including a pumping stroke when the associated crank is moving downwardly and a return stroke when the associated crank is moving upwardly; said left and right springs being constructed and arranged to enable the left and right arms to freely resiliently yield away from the limiting position thereof in response to the pumping stroke of the associated foot pedaling member by virtue of the force transmittal thereto of the associated pedaling member through the associated roller and to freely resiliently return during the return stroke of the associated foot pedaling member; and an adjustable movement resisting mechanism constructed and arranged to provide a resistance to the cycle of movement of said foot pedaling members by a user which can be adjusted so as to vary the amount of resistance provided.
