Exercise assemblies having crank members with limited rotation

摘要

An exercise assembly has a frame, a pair of elongated foot pedal members, a pair of elongated coupler arms, a pair of crank members, a pair of elongated rocker arms, and a front cross-shaft. The pair of foot pedal members are each movable along user-defined paths of different dimensions. Each crank member is rotatable in a circular path and is freely rotatable along the circular path in a first direction and restrained from rotation along the circular path in a second, opposite direction.

主权项

1. An exercise assembly, the assembly comprising:
a frame; a pair of elongated foot pedal members, each food pedal member having a front portion and a rear portion; a pair of elongated coupler arms, each coupler arm having a lower portion and having an upper portion that is pivotally connected to the frame; a pair of crank members, each crank member having a first portion that is pivotally connected to the front portion of one of the pair of foot pedal members and having a second portion that is pivotally connected to the lower portion of one of the pair of coupler arms, such that each crank member is rotatable in a circular path; a pair of elongated rocker arms, each rocker arm having a lower portion that is pivotally connected to one of the pair of foot pedal members in between the foot pad and the crank member and having an upper portion that is pivotally connected to the frame; wherein the pair of foot pedal members are each movable along user-defined paths of different dimensions; and a front cross-shaft, wherein the pair of crank members are operatively connected to the front cross-shaft such that movement of each of the pair of crank members along the circular path causes rotation of the front cross-shaft; wherein the pair of crank members are freely rotatable along the circular path in a first direction and restrained from rotation along the circular path in a second, opposite direction.
