Patent ID: 7871356

Claim:
An arm mechanism for an elliptical exerciser comprising: a linkage having a first end pivotally mounted to a frame of the elliptical exerciser, and a second end receiving a reciprocating movement from a foot pedal of the elliptical exerciser; an arm member having a handling portion to be handled by a user of the elliptical exerciser, and a coupling portion to be coupled to the first end of the linkage; a coupling mechanism for releasably coupling the linkage to the arm member, the coupling mechanism having cylinders on the arm member and on the linkage, the cylinders being axially aligned and having matching serrated surfaces for coupling engagement such that the linkage and the arm member rotate jointly about the frame upon the linkage receiving the reciprocating movement from the foot pedal in a coupled position of the coupling mechanism, and for decoupling the arm member from the linkage in a decoupled position of the coupling mechanism to prevent rotation of the arm member while the linkage rotates.
