| 摘要 |
Described herein are embodiments of stationary exercise machines having reciprocating foot and/or hand members, such as foot pedals that move in a closed loop path. Some embodiments can include reciprocating foot pedals that cause a user's feet to move along a closed loop path that is substantially inclined, such that the foot motion simulates a climbing motion more than a flat walking or running motion. Some embodiments can further include reciprocating handles that are configured to move in coordination with the foot via a linkage to a crank wheel also coupled to the foot pedals. Variable resistance can be provided via a rotating air-resistance based mechanism, via a magnetism based mechanism, and/or via other mechanisms, one or more of which can be rapidly adjustable while the user is using the machine. |

1. A stationary exercise machine, comprising:
a frame including an upper support structure; a crank shaft rotatably coupled with the upper support structure and rotatable about a crank axis; first and second connection members that each rotate about a rotation axis that substantially coincides with the crank axis; first and second crank arms coupled to the first and second connection members, respectively, to rotate about the rotation axis of its respective connection member; first and second reciprocating foot members operatively associated with the first and second crank arms, respectively, in such a manner that at least a portion of each of the first and second reciprocating foot members orbits the crank shaft as the crank shaft rotates; first and second foot pedals coupled to the first and second reciprocating foot members, respectively; first and second handles supported by the upper support structure to rotate about a handle axis; first and second reciprocating members rotatably coupled to the first and second handles, respectively; third and fourth connection members operatively associated with the crank shaft and with the first and second connection members, respectively; the third and fourth connection members each define a rotation axis that is parallel to and offset from the crank axis; and the first and second reciprocating members rotatably coupled to the third and fourth connection members, respectively, to rotate about the rotation axis defined by its respective connection member. |
