Abstract
An elliptical machine, which includes a frame body including a base and an upright column connected with the base; two movable mechanisms, each including a swing arm and a pedal rod, a first end of the swing arm being provided with a handle, a second end of the swing arm being rotatably connected to a first end of the pedal rod, a second end of the pedal rod being provided with a pedal; two adjusting mechanisms, each including a connecting rod and a driving device, the connecting rod being in swivel connection with a corresponding pedal rod, the driving device being drivingly connected with a first end of the connecting rod, for adjusting a position of a rotation center of the first end of the connecting rod; and a resistance mechanism, disposed on the frame body and movably connected with a second end of the connecting rod.
Claims7
An elliptical machine, comprising:
- a frame body comprising a base and an upright column connected with the base;
- two movable mechanisms, located at opposite sides of the upright column in a first direction, respectively, each movable mechanism comprising a swing arm, a pedal rod and a connecting rod, the swing arm being rotatably connected to the upright column, a first end of the swing arm being provided with a handle, a second end of the swing arm being rotatably connected to a first end of the pedal rod, a second end of the pedal rod being provided with a pedal, the connecting rod being rotatably connected with the pedal rod;
- two adjusting mechanisms, disposed corresponding to the two movable mechanisms, each adjusting mechanism being drivingly connected with a first end of the connecting rod of a corresponding one of the two movable mechanism, for adjusting a position of a rotation center of the first end of the connecting rod;
- a resistance mechanism, disposed on the frame body and movably connected with a second end of the connecting rod of each one of the two movable mechanisms, for applying reverse resistance to a motion of the second end of the connecting rod of each one of the two movable mechanisms;
- and
- wherein the frame body further comprises two support columns connected with the base, which are disposed corresponding to the two adjusting mechanisms;
- each adjusting mechanism comprises a telescopic unit, a rotating piece and an adjusting rod, the telescopic unit being installed on a corresponding one of the two support columns, the rotating piece being rotatably installed on the corresponding one of the two support columns, a first end of the rotating piece being rotatably connected to an output end of the telescopic unit, a first end of the adjusting rod being rotatably connected with a second end of the rotating piece, a second end of the adjusting rod being rotatably connected to the first end of the connecting rod of the corresponding one of the two movable mechanisms;
- wherein a motion trajectory of the second end of the pedal rod of each one of the two movable mechanisms has an included angle with respect to a horizontal direction, which is positively related to a height of the position of the rotation center of the first end of the connecting rod of the corresponding one of the two movable mechanisms;
- wherein the height of the position of the rotation center of the first end of the connecting rod is negatively related to a stroke of the telescopic unit of a corresponding one of the two adjusting mechanisms.
