Exercise trainer with a stride multiplier

An exercise trainer with a stride multiplier comprising:

• a base;
• first and second crank arms supported on said base substantially 180° apart on an axle having a common axis passing through each of said crank arms;
• first and second foot links pivotally connected respectively on said first and second crank arms at one end and supported for sliding movement on an end removed therefrom;
• first and second foot pedals respectively supported for longitudinal movement on said first and second foot links;
• and,
• a flexible connection between said foot pedals and a ground connection on said base and interconnected with said foot links so that said foot links when moved in supported relationship with said crank arms provide for a degenerated elliptical movement of said foot pedals such that a point on said foot pedals moves a distance greater than twice the length of its respective crank arm.

An exercise trainer comprising:

• a base;
• a wheel mounted on said base;
• an axle through said wheel having a first and second crank arm substantially 180° apart from each other mounted on said axle connected to said wheel;
• first and second foot links respectively pivotally connected to said first and second crank arms;
• a bearing surface mounted on said base removed from said pivotal mounting of said foot links to said crank arms providing reciprocal movement of said foot links on said bearing surface;
• a foot pedal mounted on each of said foot links having bearing surfaces which engage said foot links for reciprocal movement with respect to said foot links;
• a mechanical linkage between said foot pedals and said foot links;
• and,
• means for securing said mechanical linkage to a fixed portion on said base to provide relative movement of said foot pedals on said foot linkage greater than twice the length of a crank arm, and in a degenerated elliptical path.

An exercise trainer comprising:

• a first and second foot link connected and supported for opposing reciprocal movement;
• a first and second pivotal support for said foot links providing a bearing surface for reciprocal movement and support so as to allow said foot links to reciprocate;
• a first foot pedal mounted on said first foot link and a second foot pedal mounted on said second foot link;
• a flexible member connected between said foot link and said foot pedal;
• and,
• a ground connection connected to said flexible member to assist movement of said foot pedals on said foot link in a modified elliptical path.

An exercise trainer comprising:

• a first and second crank arm having a common axis supported on a frame with a base, said first and second crank arm being angularly displaced from each other;
• a flywheel connected to said crank arms;
• a first foot link and a second foot link respectively supported on said first crank arm and said second crank arm, said foot links being formed from elongated members having longitudinal channels;
• bearing support means engaging said foot link channels removed from said first and second crank arm supports for supporting said foot links for reciprocal movement as said cranks are turned;
• a first foot pedal on said first foot link and a second foot pedal on said second foot link supported for reciprocal movement on said foot link having rollers engaging the channels of said foot links;
• and,
• a flexible linkage between said foot pedal and said foot link and a fixed portion of said frame to provide reciprocal movement of said foot pedals through a degenerated ellipse having its major axis substantially four times the length of the crank arm to which it is supported.
