Abstract

Apparatus and method for simulating a back and forth leg or foot movement, the apparatus comprising: a pair of pivotable support mechanisms supported on a frame, a pair of foot pedals mounted on the support mechanisms for back and forth movement along an arcuate path of translation movement, the foot pedals being adjustable to a selected segment of an overall arcuate path of translation movement. The apparatus includes handles or arms interconnected or interlinked to the foot pedals for upper body pushing or pulling energy input. The handles or arms pivot together with and in the same back or forth direction as the pedals to which they are interlinked.

Claims

1. An apparatus for simulating a back and forth leg or foot movement comprising:

a pair of left and right foot pedals each having a foot sole receiving surface horizontally oriented relative to the ground for a user standing thereon vertically upright,

the foot pedals being mounted on a frame for movement in a back and forth direction along an arcuate path between forwardmost upward horizontal and rearwardmost downward horizontal positions;

a pair of left and right manually graspable input arms each pivotably interconnected to a respective one of the left and right foot pedals such that the left arm pivots forwardly together with forward and upward movement of the left pedal, the left arm pivots rearwardly together with backward and downward movement of the left pedal, the right arm pivots forwardly together with forward and upward movement of the right pedal and the right arm pivots rearwardly together with backward and downward movement of the right pedal.

2. The apparatus of claim 1 wherein the foot pedals are adjustable to move in an arcuate path of selected incline.

3. The apparatus of claim 1 wherein the input arms are adjustable to move in a pivot path of selected degree of pivot.

4. The apparatus of claim 1 wherein the pedals and the input arms are interconnected to a pivot mechanism adjustable to a selected degree of pivot that adjusts the arcuate path of the foot pedals and the degree of pivot of the input arms.

5. The apparatus of claim 1 wherein the arms and the pedals are interconnected to a reciprocating mechanism that directs one of the left or right pedals to travel in the back or forth direction while simultaneously directing the other of the left or right pedals to travel in an opposite direction.

6. The apparatus of claim 1 wherein the arms and the pedals are interconnected to a reciprocating mechanism that directs one of the left or right pedals to travel in the back or forth direction while simultaneously directing the other of the left or right pedals to substantially always travel in an opposite direction.

7. The apparatus of claim 5 wherein the reciprocating mechanism comprises a rotating mechanism having a pair of pivot points, one pivot point pivotably interconnected to one of the left or right pedals and arms and the other pivot point pivotably interconnected to the other of the left or right pedals and arms.

8. The apparatus of claim 5 wherein the pivot points are disposed at substantially opposing 180 degree positions along a circular path of rotation, the pedals and the arms being interconnected to a respective pivot point by a link mechanism.

9. The apparatus of claim 1 wherein the foot pedals pivot or rotate less than about three degrees during movement between the forwardmost and backwardmost positions.

10. The apparatus of claim 1 wherein each of the foot pedals are mounted on the frame via a four bar linkage mechanism.

11. An apparatus for simulating a back and forth leg or foot movement of a user comprising:

a pair of left and right foot pedals each having a foot sole receiving surface horizontally oriented relative to the ground, the foot pedals being mounted and arranged on a frame by linkages for supporting the user vertically upright and for movement in a back and forth direction along an overall arcuate path defined by the linkages;

a pair of left and right manually graspable input arms each pivotably interconnected to a respective one of the left and right foot pedals for pivoting movement in the back or forth direction;

wherein the foot pedals are adjustable to move along a selected segment of the overall arcuate path between forwardmost upward horizontal and backwardmost downward horizontal positions, the selected segment of the overall arcuate path being variably selectable by the user to have a variable degree of incline;

wherein the left arm pivots forwardly together with forward movement of the left pedal, the left arm pivots rearwardly together with backward movement of the left pedal, the right arm pivots forwardly together with forward movement of the right pedal and the right arm pivots rearwardly together with backward movement of the right pedal.

12. The apparatus of claim 11 wherein the foot sole receiving surfaces pivot or rotate less than about three degrees between the forwardmost and backwardmost positions.

13. The apparatus of claim 11 wherein the linkages comprise a four bar linkage mechanism.

14. An apparatus for simulating a back and forth leg or foot movement of a user comprising

a pair of left and right foot pedals each having a foot sole receiving surface horizontally oriented relative to the ground,

the foot pedals being mounted and arranged on a frame for supporting the user standing thereon vertically upright and for movement in a back and forth direction along any one of a plurality of reproducible user selectable segments of an arcuate path between forwardmost upright horizontal and rearwardmost downward horizontal positions;

a pair of left and right handles for being grasped by a user'"'"'s hands each pivotably interconnected to a respective one of the left and right foot pedals such the left handle pivots forwardly together with forward movement of the left pedal, the left handle pivots backwardly together with backward movement of the left pedal, the right handle pivots forwardly together with forward movement of the right pedal and the right handle pivots backwardly together with backward movement of the right pedal.
