Claim 1
Independent Claim
331 words
An exercise mechanism comprising a support frame including a base, a post extended upward from said base and including two side walls, a stay extended upward from said base to interconnect with said post at a point between its ends, said post including a slot formed in a lower portion of each of said side walls thereof and a groove formed in an upper portion of each of said side walls thereof; a pair of laterally adjacent foot pedals pivotally mounted at one end on said stay at a location above said base, each of said foot pedals including a shaft fixed thereto and extended through a respective slot of said post and extended into said post; a handle slidable along each of said grooves and having one end located in said post; resistance means interconnected between said foot pedals and a location on said support frame above said foot pedals; a first pulley rotatably disposed in top of said post, a second pulley and a third pulley provided in said post, in which said second pulley being located above said third pulley; a rope coupled between said second pulley and said shaft fixed to a first foot pedal; a cord coupled between said third pulley and said shaft fixed to a second foot pedal; a cable having one end fixed to a first side wall and extended downward and over said second pulley, extended upward and fixed to a first handle, extended upward and over said first pulley, extended downward and fixed to a second handle, extended downward and over said third pulley, extended upward and having the other end fixed to a second side wall of said post; said first foot pedal being caused to move upward when said second handle is pulled downward and when said second foot pedal is pressed downward, and said second foot pedal being caused to move upward when said first handle is pulled downward and when said first foot pedal is pressed downward.
Claim 2
Dependent Claim
331 words
An exercise mechanism comprising a support frame including a base, a post extended upward from said base and including two side walls, a stay extended upward from said base to interconnect with said post at a point between its ends, said post including a slot formed in a lower portion of each of said side walls thereof and a groove formed in an upper portion of each of said side walls thereof; a pair of laterally adjacent foot pedals pivotally mounted at one end on said stay at a location above said base, each of said foot pedals including a shaft fixed thereto and extended through a respective slot of said post and extended into said post; a handle slidable along each of said grooves and having one end located in said post; resistance means interconnected between said foot pedals and a location on said support frame above said foot pedals; a first pulley rotatably disposed in top of said post, a second pulley and a third pulley provided in said post, in which said second pulley being located above said third pulley; a rope coupled between said second pulley and said shaft fixed to a first foot pedal; a cord coupled between said third pulley and said shaft fixed to a second foot pedal; a cable having one end fixed to a first side wall and extended downward and over said second pulley, extended upward and fixed to a first handle, extended upward and over said first pulley, extended downward and fixed to a second handle, extended downward and over said third pulley, extended upward and having the other end fixed to a second side wall of said post; said first foot pedal being caused to move upward when said second handle is pulled downward and when said second foot pedal is pressed downward, and said second foot pedal being caused to move upward when said first handle is pulled downward and when said first foot pedal is pressed downward.
Claim 3
Dependent Claim
89 words
An exercise mechanism according to claim 1, wherein a rib is longitudinally formed in an upper portion of said post and located below said first pulley such that a space is formed between said rib and each of said side walls of said post, each of said handles includes a block fixed to said one end thereof and slidable along a respective space formed between said rib and said side walls of said post so that said handles can be guided to move up and down along said spaces.
Claim 4
Dependent Claim
326 words
An exercise mechanism comprising a support frame including a base, a post extended upward from said base and including two side walls, a stay extended upward from said base to interconnect with said post at a point between its ends, said post including a slot formed in a lower portion of each of said side walls thereof and a groove formed in an upper portion of each of said side walls thereof; a pair of laterally adjacent foot pedals pivotally mounted at one end on said stay at a location above said base, each of said foot pedals including a shaft fixed thereto and extended through a respective slot of said post and extended into said post; a handle slidable along each of said grooves and having one end located in said post; resistance means interconnected between said foot pedals and a location on said support frame above said foot pedals; a first pulley rotatably disposed in top of said post, a second pulley and a third pulley provided in said post, in which said second pulley being located above said third pulley; a cord coupled between said third pulley and a first foot pedal; a rope coupled between said second pulley and a second foot pedal; a cable having one end fixed to a first side wall of said post and extended downward and over said second pulley, extended upward and fixed to a first handle, extended upward and over said first pulley, extended downward and fixed to a second handle, extended downward and over said third pulley, extended upward and having the other end fixed to a second side wall of said post; said second foot pedal being caused to move upward when said second handle is pulled downward and when said first foot pedal is pressed downward, and said first foot pedal being caused to move upward when said first handle is pulled downward and when said second foot pedal is pressed downward.
Claim 5
Dependent Claim
326 words
