EXERCISE MACHINE

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.

主权项

1. A stationary exercise machine comprising:
a stationary frame; a crankshaft mounted to the stationary frame to rotate about a crankshaft axis; first and second handles operatively associated with first and second virtual crank arms, respectively, to convert a user's input force at the first and second handles into a first moment on the crankshaft; first and second crank arms fixedly connected to the crankshaft and rotatable about the crankshaft axis, the first and second crank arms pivotally connected to first and second lower reciprocating members, respectively, at a respective pivot axis; each of the pivot axes orbit the crankshaft axis; and an angle between the first and second crank arms and corresponding first and second virtual crank arms is between approximately 60 and 90 degrees.
