Exercise assemblies having foot pedal members that are movable along user defined paths
An exercise assembly comprises a frame and elongated foot pedal members that are each movable along user-defined paths of differing dimensions. Each foot pedal member has a front portion and a rear portion. Footpads are disposed on the rear portion of one of the pair of foot pedal members. Elongated coupler arms have a lower portion and an upper portion that is pivotally connected to the frame. Crank members have a first portion that is pivotally connected to the front portion of one of the pair of foot pedal members and have 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. Elongated rocker arms have 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 have an upper portion that is pivotally connected to the frame.
1. An exercise assembly comprising:
a frame;
a first pedal member that has a first portion and a second portion;
a second pedal member that has a first portion and a second portion;
a first coupler arm that has a first portion and a second portion, wherein the second portion of the first coupler arm is pivotally coupled to the frame;
a second coupler arm that has a first portion and a second portion, wherein the second portion Of the second coupler arm is pivotally coupled to the frame;
a first crank member that has a first portion that is pivotally coupled to the first portion of the first pedal member and a second portion that is pivotally coupled to the first portion of the first coupler arm; and
a second crank member that has a first portion that is pivotally coupled to the first portion of the second pedal member and a second portion that is pivotally coupled to the first portion of the second coupler arm;
wherein the first crank member is rotatable in a circular path entirely around the first portion of the first coupler arm as the first coupler arm pivots back and forth with respect to the frame and wherein the second crank member is rotatable in a circular path entirely around the first portion of the second coupler arm as the second coupler arm pivots back and forth with respect to the frame, such that the first and second pedal members are each movable along user defined paths of differing dimensions.
2. The exercise assembly according to claim 1 , further comprising a first rocker arm that has a first portion that is pivotally coupled to the first pedal member and a second portion that is pivotally coupled to the frame and a second rocker arm that has a first portion that is pivotally coupled to the second pedal member and a second portion that is pivotally coupled to the frame.
3. The exercise assembly according, to claim 2 , further comprising, first handle on the first rocker arm and a second handle on the second rocker arm.
4. The exercise assembly according to claim 3 , wherein the second portions of the first and second rocker arms pivot about a common axis.
5. The exercise assembly according to claim 4 , wherein the first and second rocker arms are pivotally coupled to the frame via a rear cross-shaft.
6. The exercise assembly according to claim 2 , further comprising a cross-linking mechanism that pivotally connects the first and second rocker arms together.
7. An exercise assembly comprising:
a frame;
a first pedal member that has a first portion and a second portion;
a second pedal member that has a first portion and a second portion;
a first coupler arm that has a first portion and a second portion, wherein the second portion of the first coupler arm is pivotally coupled to the frame;
a second coupler arm that has a first portion and a second portion, wherein the second portion of the second coupler arm is pivotally coupled to the frame;
a first crank member that has a first portion that is pivotally coupled to the first portion of the first pedal member and a second portion that is pivotally coupled to the first portion of the first coupler arm; and
a second crank member that has a first portion that is pivotally coupled to the first portion of the second pedal member and a second portion that is pivotally coupled to the first portion of the second coupler arm;
wherein the first crank member is rotatable in a circular path about the first portion of the first coupler arm as the first coupler arm pivots back and forth with respect to the flame and wherein the second crank member is rotatable in a circular path about the first portion of the second coupler arm as the second coupler arm pivots back and forth with respect to the frame, such that the first and second pedal members are each movable along user defined paths of differing dimensions; and
first and second timing belts coupled to the second portions of the first and second crank members, respectively, such that movement of the first and second crank members along, the circular paths causes rotation of the respective first and second timing belts.
8. The exercise assembly according to claim 7 , further comprising first and second lower timing pulleys coupled to the first and second crank members, respectively, and transferring rotational movement of the respective first and second crank members to the first and second timing belts.
9. The exercise assembly according to claim 8 , further comprising first and second upper timing pulleys coupled to a front cross-shaft and respectively transferring rotational movement of the first and second timing belts to the front cross-shaft.
