Abstract:
An exercise device comprising:a frame configured to be supported on a floor, said frame having a first and a second pivot axis defined thereupon;a first and a second guide link, each guide link having a first and a second attachment point defined thereupon, each guide link being pivotally attached, through its first attachment point, to said frame at the first pivot axis thereof;a first and a second foot link, each foot link being pivotally attached to a respective one of said first and second guide links through the second attachment point thereof;a first and a second crank arm, each being pivotally attached to said frame at said second pivot axis so as to be rotatable thereabout;a first and a second intermediate link, each having a first connection point mechanically coupled to a respective one of said guide links, and a second connection point mechanically coupled to a respective one of said crank arms, so that rotation of said first and second crank arms about said second pivot axis causes said respective first and second guide links to pivot about said first pivot axis;a first and a second control member, each having a first junction point affixed to a respective one of said foot links;first and second reciprocating means, each in mechanical communication with a respective one of said crank arms and with a second junction point defined on a respective one of said first and second control members, each of said reciprocating means being operable to reciprocate the second junction point of its respective control member as its respective crank arm rotates about the second pivot axis, so that its respective control member is operative to vary an angle defined between its respective foot link and its associated guide link, as said guide link pivots about said first pivot axis.
