Abstract
A coupling mechanism for an exercise apparatus is disclosed. The coupling mechanism may include a resistance source coupled with a housing, a rod coupled to the resistance source, a clevis coupled to the rod, and a cam rotatably coupled to the clevis about an axis. The cam may include a curved outside surface with a first channel, and a curved inside surface with a second and third channel. The coupling mechanism may also include a cable key coupled to the cam and several cables.

A coupling mechanism for an exercise apparatus, the coupling mechanism comprising:
- a resistance source rotatably coupled with a housing;
- a rod coupled to the resistance source;
- a clevis coupled to the rod;
- a cam rotatably coupled to the clevis about an axis, the cam comprising:
- a curved outside surface having a first channel;
- and
- a curved inside surface having a second channel and a third channel;
- a first cable, wherein one end of the first cable is coupled to one or more resistance engagements and another end of the cable is connected to the cam;
- and
- a second cable and a third cable coupled to the housing on one end and the cam on another end.
A coupling mechanism for an exercise apparatus, the coupling mechanism comprising:
- a resistance source rotatably coupled with a housing;
- a rod coupled to the resistance source and configured to oscillate in a linear direction;
- a clevis coupled to the rod;
- a cam rotatably coupled to the clevis about an axis, the cam comprising:
- a curved outside surface;
- and
- a curved inside surface positioned opposite the curved outside surface;
- one or more tension members coupled to the cam and disposed on the curved outside surface, wherein a first portion of the one or more tension members extends away from the cam tangentially adjacent to the curved outside surface, wherein a second portion of the one or more tension members extends away from the cam tangentially adjacent to the curved inside surface;
- and
- an anchor attached to the housing and coupled to the second portion of the one or more tension members;
- and
- a movable resistance engagement coupled to the first portion of the one or more tension members.
