Patent ID: 8668629

Claim:
A multimode exercise device, comprising: a chassis with two opposing elongated sides; an exercise mechanism mounted onto the chassis comprising on each side of the chassis: a slidable assembly that is configured to move backward and forward along one elongated side of the chassis; a rotatable wheel configured to rotate about an axis at its center and mounted onto the slidable assembly; a pedal coupled to the rotatable wheel configured to rotate the rotatable wheel; a restraining rod that is rotatably coupled to a side of the chassis on a first end and rotatably coupled to the rotatable wheel at one of a plurality of user selectable attachment positions on the second end; and a synchronizing mechanism to synchronize between the rotations of the rotatable wheels on both sides of the chassis; and wherein each side of the chassis further comprises: a drive gear coupled to the rotatable wheel and configured to rotate with the rotatable wheel; a telescopic drive shaft coupled to the drive gear for passing on the motion of the rotatable wheel; and a synchronization gear that receives the motion of the rotatable wheel via the telescopic drive shaft and is intermeshed with the synchronization gear of the other side to synchronize between the motion of the rotatable wheels on both sides of the chassis.
