Roller Supported Pedal Arm Elliptical

An elliptical walking exercise machine comprising:

• a. a base assembly for supporting the elliptical walking exercise machine on a floor;
• b. a base upper pivot connecting a right handle and a left handle to the base assembly, wherein the base upper pivot provides a pendulum like motion for the right handle and left handle, wherein the right handle and left handle are above the base upper pivot;
• c. a right third link connected below the right handle and a left third link connected below the left handle, wherein the right third link and the left third link are substantially upright and are provided a pendulum like motion about the base upper pivot, the right third link having a right bottom end and the left third link having a left bottom end;
• d. a right second pivot connected at the right bottom end and a left second pivot connected a left bottom end;
• e. a right second link connected to the right second pivot, and a left second link connected to the left second pivot, wherein the right second link and the left second link are somewhat horizontally oriented and also received a pendulum like motion relative to the base;
• f. a left pedal connected to the left second link and a right pedal the right second link;
• g. a main wheel receiving force from user movement of the left third link, the right third link, the left second link and the right second link;
• h. a base crank pivot for mounting the main wheel, wherein the main wheel rotates about the base crank pivot;
• i. a right crank arm fixed to the main wheel, and a left crank arm fixed to the main wheel, wherein the right crank arm and the left crank arm are fixed to have the same angular position as the main wheel, wherein the right crank arm and the left crank arm are mounted at an offset of each other of approximately 180°;
• j. a right first link connected to the right crank arm at a right crank pivot and a left first link connected to the left crank arm at a left crank pivot;
• k. a force unit providing resistance to the main wheel;
• l. an elliptical movement mechanism comprising:
• i. a right first link connected to the right first pivot, and a left first link connected to the left first pivot, wherein the right first pivot is located on the right second link behind the right second pivot and wherein the left first pivot is located on the left second link behind the left second pivot, a forward end of the right first link connecting to the right crank pivot, and a forward end of the left first link;
• wherein the right first pedal is mounted not to slide along a length of the right second link, and wherein the left first pedal is mounted not to slide along a length of the left second link;
• ii. a left roller mounted on a left crank step and a right roller mounted on a right crank step, wherein the right second link has a right contact surface and the left second link as a left contact surface, wherein the right contact surface is adapted to engage the right roller, and wherein the left contact surface is adapted to engage the left roller;
• iii. wherein a rear end of the right second link and a rear end of the left second link have substantially elliptical motion while the left first pedal and the right first pedal have substantially elliptical motion.
