Exercise and therapeutic trainer
First Claim
1. An exercise trainer to provide exercise movement to a user comprising:
- a first crank arm and a second crank arm oriented at an angular distance from the other;
a first foot link connected to said first crank arm and a second foot link connected to said second crank arm;
foot pedals supported on said foot links for relative movement with respect to said foot links;
a bearing support for said foot links at a point removed from said first and second crank arms to which said first and second foot links are supported for sliding reciprocating movement;
a connection between a grounded point and said foot pedals interconnected with said foot links to provide relative horizontal movement of said foot pedals at least twice the length of each respective crank arm; and
, a seat mounted on said trainer to provide for a user sitting on said trainer and placing the user'"'"'s feet on said foot pedals for exercise movement.

Abstract
An exercise trainer having a first crank arm and a second crank arm respectively connected to a first foot link and a second foot link with foot pedals supported on the foot links, and bearing supports for the foot links removed from the crank arms. A flexible connection connects a ground point, the foot pedals, and the foot links to provide relative movement in a modified ellipse as to the ground point of at least twice the length of each crank arm. A seat is mounted on the trainer having a motor and control for raising and lowering the seat with respect to the foot pedals. The first and second crank arms are connected to a motor for driving the crank arms at a given speed which can supplement a user'"'"'s effort or provide a load to a user beyond a given speed.

8. An exercise trainer with a leg movement multiplier and a seat comprising:
-
a base;
first and second crank arms rotationally supported angularly apart on said base;
first and second foot links connected respectively to said first and second crank arms at one end and supported for sliding movement distally from said crank arms;
first and second foot pedals respectively supported for longitudinal movement on said first and second foot links;
a 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 horizontal elliptical movement of said foot pedals greater than twice the length of its respective crank arm; and
,a seat mounted on said base having a height adjustment with respect to the foot pedals. - View Dependent Claims (9, 10, 11)

12. An exercise trainer comprising:
-
a base;
a first and second crank arm angularly apart from each other mounted on said base;
a motor connected to said crank arms for driving said crank arms;
first and second foot links respectively connected to said first and second crank arms;
a bearing surface mounted on said base removed from said connection of said foot links to said crank arms providing reciprocal movement of said foot links;
a foot pedal mounted on each of said foot links having a bearing surface which engages said foot links for reciprocal movement with respect to said foot links;
a linkage between said foot pedals and said foot links;
a securement for securing said linkage to a fixed portion on said base to provide relative horizontal movement of said foot pedals greater than twice the length of a crank arm, and in a degenerated elliptical path; and
,a seat mounted for movement by a motor up and down with respect to said foot pedals in order to raise and lower a user with respect to said foot pedals. - View Dependent Claims (13, 14)

15. An exercise trainer comprising:
-
a first and second foot link connected and supported for opposing reciprocal movement;
a 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 connecting member connected between said foot link and said foot pedal;
a base with a ground connection connecting said base to said connecting member to assist movement of said foot pedals on said foot link in a modified elliptical path;
a seat mounted on said exerciser for raised and lowered placement with respect to said pedals; and
,a motor for driving said foot pedals. - View Dependent Claims (16, 17, 18)

19. An exercise trainer having a seat 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 first foot link and a second foot link respectively supported on said first crank arm and said second crank arm;
a support for supporting said foot links removed from said first and second crank arm supports 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;
a 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 greater than the length of the crank arm to which it is supported;
a seat mounted on said exercise trainer having an adjustable seat mounting for moving said seat as to its distance with respect to said first and second foot pedals; and
,a motor connected to said seat for adjusting the distance of said seat with respect to said pedals. - View Dependent Claims (20, 21, 22, 23)

24. An exercise trainer having a seat comprising:
-
a motor and a seat positioned generally vertically higher than said motor;
a first crank arm and a second crank arm angularly offset from each other connected to said motor for rotational movement;
a first foot link connected to said first crank arm and a second foot link connected to said second crank arm;
a first foot receiving member and a second foot receiving member respectively connected for movement on said first foot link and said second foot link;
a linkage between said first foot link and said foot receiving member interconnecting them, a linkage between said second foot link and said foot receiving member, both of said linkages connected to a ground point so that said foot links when reciprocated cause said foot receiving members to reciprocally move on said foot links in relative displacement with respect to said ground; and
