Abstract

The subject matter discloses an exercising device enabled to switch between elliptical course and circular course of footrests used by a user, comprising two main wheels, each connected to a different footrest; two connecting rods, the distal end of each connecting rod is connected to each main wheel and the proximal end of each connecting rod is connected to the body of the exercising device, said connecting rods are enabled to move the two main wheels on a horizontal axis.

The subject matter also discloses A mechanism within an exercising device enabling both elliptical and circular movement of a footrest in the exercising device, the mechanism comprising: a main wheel connected to the footrest and rotated upon movement of the footrest; a connecting rod connected on its proximal end to the body of the exercising device and on its distal end to the main wheel; wherein the course of the footrest'"'"'s movement is elliptical when the distal end is connected to a non-centric position on the main wheel and circular when the connecting rod is connected to a centric position on the main wheel or when the connecting rod is not connected to both the main wheel and the body of the exercising device.

The footrests and handlebars of the exercising device fit the new motions enabled by the device. A stepper can also be embedded within the exercising device of the disclosed subject matter.

Claims

1. An exercising device enabled to switch between elliptical course and circular course of footrests used by a user, comprising:

two main wheels, each connected to a different footrest;

at least one connecting rod connected to the two main wheels, said at least one connecting rod is enabled to move the two main wheels on a horizontal axis.

2. The exercising device according to claim 1, wherein the at least one connecting rod is at least two connecting rods.

3. The exercising device according to claim 2, wherein the distal end of each of the at least two connecting rods is connected to each main wheel and the proximal end of each of the at least two connecting rods is connected to the body of the exercising device.

4. The exercising device according to claim 1, further comprising a power-generating module for maneuvering the at least one connecting rods.

5. The exercising device according to claim 1, further comprising a control unit for controlling the movement of the at least one connecting rods.

6. The exercising device according to claim 1, wherein controlling the movement of the at least one connecting rod is performed mechanically.

7. The exercising device according to claim 1, wherein the footrest is folded when the course of the footrest'"'"'s movement is circular and unfolds when the course of the footrest'"'"'s movement is elliptical.

8. The exercising device according to claim 1, wherein the footrest is a pedal.

9. The exercising device according to claim 1, wherein the control unit determines parameters selected from a group consisting of the amplitude, velocity, frequency and phase of the at least one connecting rod'"'"'s movement.

10. The exercising device according to claim 1, further comprising two interconnected secondary wheels, each secondary wheel is limited to vertical movement and connected to a different main wheel, wherein both secondary wheels are in the same height.

11. The exercising device according to claim 10, wherein the two interconnected secondary wheels affix the two main wheels in the same distance from the center of the range of the horizontal movement of the main wheels.

12. The exercising device according to claim 1, wherein the movement of the footrests is elliptical when the two main wheels are moved on the horizontal axis and circular when the two main wheels are not moved on the horizontal axis.

13. The exercising device according to claim 1, wherein the distal end of the at least one connecting rod is connected to the center of the main wheel.

14. A mechanism within an exercising device enabling both elliptical and circular movement of a footrest in the exercising device, the mechanism comprising:

a main wheel connected to the footrest and rotated upon movement of the footrest;

a connecting rod connected on its proximal end to the body of the exercising device and on its distal end to the main wheel;

wherein the course of the footrest'"'"'s movement is elliptical when the distal end is connected to a non-centric position on the main wheel and circular when the connecting rod is connected to a centric position on the main wheel or when the connecting rod is not connected to both the main wheel and the body of the exercising device.

15. The mechanism according to claim 14, further comprising a secondary wheel for synchronizing the movement of the main wheel to the movement of another main wheel connected to another footrest.

16. A mechanism for changing the surface area of a footrest while exercising, comprising:

a footrest composed of at least two surfaces connected serially;

a rotation axis connected to at least one of the surfaces such that at least one surface rotates on the rotation axis and folds on or beneath another surface.

17. The mechanism according to claim 16, wherein said footrest rotates within said rotation axis such that the surface of said pedal may be parallel to the vertical or horizontal axes.

18. The mechanism according to claim 16, further comprises a locking mechanism for securely holding the pedal perpendicular to the ground.

19. A handlebar for an exercising device enabling both elliptical and circular range of movement of a footrest, wherein the handlebar is immobile in case of circular course and move in case of elliptical course.

20. The handlebar according to claim 19, wherein the handlebar comprises two portions, each associated with a different footrest, wherein the movement of each portion of the handlebar is a function of the movement of the associated footrest.

21. A method for providing elliptical movement of a device connected to a wheel, the method comprising:

rotating the device connected to the wheel on the course of movement of the wheel; and

generating linear movement of the wheel.
