A device for the therapeutic treatment and/or training of the lower extremities of a human having driven and controlled movement devices which are connected to a stationary frame and comprise holding members for fastening of one extremity. The holding members can be moved independently of one another along walking trajectories, wherein the movement devices each comprise a pivot arm pivotable into different elevations, the pivot arm being rotatably connected to one single sled on a linear track. A first rotational drive is attached to a single sled and is connected to the pivot arm for changing the elevation of the respective holding member. The pivot arm comprises a second rotational drive for changing the inclination of the respective holding member and the sled is connected to a linear drive for changing the longitudinal position of the respective holding member.

A device for the therapeutic treatment and/or training of the lower extremities of a human has independent driven and controlled movement devices which are connected to a stationary frame. Each of the movement devices include foot plates that are moved independently of one another along walking trajectories. Each movement device has a pivot arm pivotable into different elevations where the pivot arm is rotatably connected to a single sled on a linear track. A first rotational drive is attached to the sled and is connected to the pivot arm for changing the elevation of the respective holding member. A second rotational drive changes the inclination of the foot plate and the sled is connected to a linear drive for changing the longitudinal position of the foot plate.

A stepping exercise machine includes a support unit, a transmission unit and a tread unit. The support unit includes a support beam and a plurality of support legs connected to the support beam. The transmission unit includes a lever. The lever is pivotally connected to a connecting member provided on the support beam. Two sides of the lever are an effort arm and a resisting arm with the connecting member as a fulcrum. The two sides of the lever are connected to two ends of the support beam through tension springs, respectively. The tread unit includes a pair of pedals. The pedals are connected to two ends of the lever. The transmission unit further includes a pair of swing rods. First ends of the swing rods are pivotally connected to the connecting member. Second ends of the swing rods are pivotally connected to lower ends of the pedals, respectively.

The present disclosure relates to a stair steppers, comprising a base, a bracket and a motion mechanism, the base supports the bracket, and the motion mechanism is disposed on the bracket, the bracket comprises a main body fixed to the base and a guide rail hinged to the main body, the guide rail is disposed to be inclined to the base, the motion mechanism comprises pedal links, pedals and pedal cranks, the pedal is disposed on the pedal link, the pedal link is hinged to the pedal crank, the pedal cranks are further hinged to the main body of the bracket, a hinge point of the pedal crank and the pedal link is disposed to be spaced apart from a hinge point of the pedal crank and the main body, the pedal link is provided with an abutting portion which abuts against the guide rail and is reciprocatingly movable along the guide rail. Since the guide rail is hinged to the main body, it is feasible to adjust an inclination angle of the guide rail relative to the base so as to change a movement trajectory of the pedal links and thereby adjust the difficulty of exercise of the stair steppers. When an angle between the guide rail and the base is larger, the difficulty of exercise is higher, otherwise, the difficulty of exercise is lower.

Embodiments of an exercise machine are disclosed. In one embodiment, an exercise machine includes a base frame, a pair of left and right pedal assemblies, and a pedal supporting assembly. The base frame is adapted to be positioned on a support surface. The left and right pedal assemblies have a pair of left and right pedals, and each is positioned over and rotatably supported by the base frame. The pedal supporting assembly is attached to the base frame and configured to pivot around an axis. The pedal supporting assembly also supports the left and right pedal assemblies. The pedal supporting assembly is operable to generate resistance in response to movement of the left and right pedals and the pedal supporting assembly pivoting around the axis.

A figure trimmer comprises a base, a pedal set, and a rotating assembly. The pedal set comprises a left pedal and a right pedal. The rotating assembly movably connects with the base. The rotating assembly is able to rotate about a shaft of the base. The rotating assembly comprises two ends, in which one end includes a first shaft and the other includes a second shaft. The left pedal can rotate about the first shaft, and the right pedal can rotate about the second shaft.
