Exercise apparatus
An exercise apparatus ( 10 ) has two wheels ( 12, 12 ′) rotatably mounted to a base ( 14, 14 ′), spaced apart and each located within a pair of wheel housings ( 15, 15 ′), respectively. Pivotably connected to each wheel is a cam ( 16 ). Another end of the cam ( 16 ) is pivotably connected to a push rod ( 17 ) which is pivotably connected to a handle ( 18 ) which is rotatably mounted in a housing ( 20 ). The pair of handle housings ( 20 ) are pivotably and respectively mounted to the pair of cams ( 16 ) such that movement of each arm in a vertical plane up or down by operating on the respective handle causes an elliptical rotation of the respective cam relative to the respective wheel ( 12, 12 ′).
1. An exercise apparatus comprising at least one wheel, wherein each wheel is respectively and pivotably connected to a first end of a bar, a second end of the bar being respectively and pivotably connected to an actuating member, wherein each actuating member is respectively and pivotably mounted and comprises a handle mounted thereto, respectively, such that movement of the handle is possible while the respective bar is displaced during use, wherein a rotation opposing means is associated with each wheel to provide a variable resistance to rotation of the respective wheel, wherein movement of the respective bar relative to the respective wheel is elliptical, and wherein the exercise apparatus further comprises a seat located a vertical distance above the at least one wheel.
2. The exercise apparatus as claimed in claim 1 , wherein each wheel is magnetic and the respective rotation-opposing means comprises at least one magnet.
3. The exercise apparatus as claimed in claim 1 , wherein the rotation-opposing means comprises a torsion spring having a resistance that can be varied.
4. The exercise apparatus as claimed in claim 1 , wherein the rotation-opposing means comprises webbing which can extend at least partially around a circumference of the respective wheel to provide the variable resistance to the rotation of the respective wheel.
5. The exercise apparatus as claimed in claim 1 , wherein the rotation-opposing means comprises one or more blades mountable onto a surface of the respective wheel to resist the rotation by providing resistance against a fluid.
6. The exercise apparatus as claimed in claim 5 , wherein the fluid comprises air, liquid, or a combination thereof.
7. The exercise apparatus as claimed in claim 1 , wherein the exercise apparatus is a hand-operated elliptical trainer.
8. The exercise apparatus as claimed in claim 1 , wherein a vertical height of the seat can be adjusted.
9. The exercise apparatus as claimed in claim 1 , wherein the seat is moveably mounted and can be moved in a plane with respect to the exercise apparatus.
10. The exercise apparatus as claimed in claim claim 1 , wherein the at least one wheel comprises a first wheel and a second wheel, the at least one bar comprises a first bar and a second bar, the actuating members comprise a first actuating member and second actuating member, and the handles comprise a first handle and a second handle, wherein the first bar is pivotably connected to the first wheel at one end and pivotably connected at another end to the first actuating member,
wherein the first actuating member is pivotably mounted and comprises the first handle mounted thereto such that movement of the first handle is possible while the first bar is displaced during use; and
wherein the second bar is pivotably connected to the second wheel at one end and pivotably connected at the another end to the second actuating member, wherein the second actuating member is pivotably mounted and comprises the second handle mounted thereto such that movement of the second handle is possible while the second bar is displaced during use; and
wherein the rotation-opposing means are respectively associated with first and second wheels to provide the variable resistance to the rotation of the first and second wheels and wherein the movement of the first and second bars relative to the first and second wheels is elliptical.
11. The exercise apparatus as claimed in claim 10 wherein the first and second wheels are spaced apart and respectively mounted on a first base and a second base.
12. The exercise apparatus as claimed in claim 1 , wherein the at least one wheel is two wheels, and wherein the seat is disposed between the two wheels.
13. The exercise apparatus as claimed in claim 1 wherein the each handle is rotatably mounted within a housing.
14. The exercise apparatus as claimed in claim 13 wherein each handle has a plurality of grip positions configured for a user to engage with the respective handle.
15. The exercise apparatus as claimed in claim 14 wherein the handles comprise grip elements configured for minimizing slippage and lift-off of hands of the user.
16. The exercise apparatus as claimed in claim 1 wherein each wheel is moveably mounted on a base.
17. The exercise apparatus as claimed in claim 16 , wherein each wheel is independently moveable relative to one another.
