Patent ID: 7462135

Claim:
An elliptical fitness machine having inclination adjusting mechanism comprises: a first frame, a second frame supported by the first frame, and an enabling assembly for enabling the second frame to rotate with respect to the first frame, wherein the first frame securely supported on a floor and the second frame mounted with an elliptical structure, and the second frame pivotally coupled to the first frame by a pivotal axle, such that the second frame and the elliptical structure can be rotated with respect to the first frame to change the inclination of the second frame when the enabling assembly actuates, wherein the enabling assembly including a support rod and an actuating device, the support rod pivotally coupled to the rear end of the second frame, and the actuating device coupled between the support rod and the second frame, and the actuating device including a body and a contractible rod, and the contractible rod can be contracted with respect to the body to swing the support rod to an angle, and wherein the elliptical structure comprising a rotating member coaxially coupled to two cranks to define a rigid body corresponding to an axle, and two pedal arms, and the middle of the rotating member and the two cranks pivotally coupled with the second frame by the axle, each crank having an eccentric pivotal point, each pivotal point of each crank pivotally coupled to a first end of one corresponding pedal arm, and each pedal arm including a footrest capable of moving in an elliptic path.
