Abstract:
1. An exercise apparatus comprising: a frame having a fixed unit and a movable unit being movable relative to the fixed unit; an adjusting mechanism coupled to the frame for orienting the movable unit; a crank assembly having a pair of crank units which are respectively and pivotally coupled to the frame about a first axis; first and second reciprocating members respectively and pivotally coupled to the frame about a second axis; first and second linkages, each linkage having a first, second and third connecting portions, the first connecting portions respectively and pivotally coupled to the crank units and moving along a circular path about the first axis, the second connecting portions respectively and pivotally coupled to the first and second reciprocating members and moving reciprocally between a first and second retracing points of a curved path about the second axis, the first retracing and the second retracing points defining a straight line passing through the circular path, the second connecting portions respectively being higher than the first connecting portions and the first retracing point being higher than the second retracing point of the curved path, the third connecting portions respectively being lower than the first connecting portions; first and second swing arms, each swing arm having a top end and a bottom end, the top ends respectively and pivotally coupled to the frame about a third axis; and first and second supporting arms, each supporting arm having a first part, a second part and a third part, the first parts respectively and pivotally coupled to the bottom ends of the first and second swing arms, the second parts respectively arranged in front of the first parts and pivotally coupled to the third connecting portions of the first and second linkages for moving along a first closed path, the third parts respectively arranged behind the first parts for supporting a user's feet and moved along a second closed path; wherein at least one of the first axis, the second axis and the third axis is mounted on the movable unit of the frame and at least one of distances among the first axis, the second axis and the third axis will be changed while the movable unit is moved by the adjusting mechanism whereby inclination of the second closed path relative to the ground will be changed when the movable unit is moving.
