Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a fitness stair climbing machine. Background Art

[0002] A stair climber is a highly effective fitness device with a unique motion and a range of functions. It provides a high-intensity, low-stress, full-body workout, significantly impacting both health and fitness. The stair climber's motion simulates the movements of climbing a mountain or staircase, providing a gradually increasing intensity workout through alternating foot movements.

[0003] Existing stair climbers include a frame, two inclined straight tracks, and two pedals. The two straight tracks are connected to the frame, and the two pedals are slidably mounted on the two straight tracks. A pull rope is provided between the upper portions of the two straight tracks, with the ends of the pull rope connected to the two pedals, respectively. An elastic rope is also connected between the two pedals. The elastic rope in the above-mentioned stair climber only produces significant resistance when the two pedals are in a high and low position. This causes the resistance felt by the feet to be intermittent during the alternating movement, which does not provide a good experience for people during the simulated climbing process. Moreover, the elastic rope connecting the two pedals causes the two pedals to press against the outer edges of the tracks during the alternating movement, ultimately preventing the two pedals from smoothly alternating.
