On the armrest bracket (1 5), and apply force to the legs to stagger back and forth, please refer to the fifth to eighth figures, the foot pedal (61) is driven by the leg force to drive the pedal (56) The walking link sets (50) on both sides of the linkage are respectively oscillated with respect to the fulcrum shaft (140) in a staggered manner, and the front end of the lower link (51) is connected to the axle link to rotate the 10 M383421 rotating wheel (20), and then through Train the resistance wheel _ through the interlocking belt (4 〇) to increase the resistance of the stepping motion, thereby achieving the training of the leg muscles. Body effect. From the fulcrum shaft (10) of the upper link of the stroller linkage (5 〇) (called at the front end pivoted to the side frame 04), the front and rear ends of the upper link (53) will be - It swings up and down with respect to the fulcrum axis ((10)), and the ❹(4) of the pedal forms a high and low undulation of the ups and downs, which improves the movement effect. Further, since the foot pedal (61) is pivotally disposed on the # step bar (56) in a swingable manner, and is equipped with the arrangement of the drawbar (62), each walking link group (5〇) is before and after When swinging, the pedals (61) can be simultaneously controlled to move to different positions', and different tilt angles are displayed relative to the pedals (56) to adapt to the bending state of the user's foot. A pedal assembly (6〇) that conforms to changes in the bending angle of the human foot and enhances comfort during exercise, and provides a natural and comfortable pedaling function for the user. Further, please refer to the fourth, fifth to eleventh drawings. The adjustable span elliptical stepper of the present invention is provided with an adjustment connection seat (55) on the connecting rod (54) after each walking link group (5〇). ), after the positioning bolt (552) of the adjusting connecting seat (55) is disassembled, the sliding sleeve (551) is slidable up and down with respect to the rear connecting rod (54), and is adjusted to make the sliding sleeve (551) The perforation corresponds to the positioning holes (550) of other different heights on the rear connecting rod (54), and then the positioning bolt (552) is locked, so that the rear connecting (54) and the lower connecting # (51) rear end pivoting can be changed. The position is thereby adjusted to adjust the swing of the rear link (54) and further change the span size of the pedal (56) and the pedal assembly (6〇). Referring to Figures 5 to 8, when the sliding sleeve (551) of the adjusting joint (55) is adjusted to the positioning hole (55〇) on the upper side of the rear link (54), the rear link M383421 forms a large swing. The pedal assembly has a small height fluctuation, and the front and rear spans of the pedaling (56) and the pedal assembly (6〇) are increased; please refer to the ninth to tenth drawings when adjusting the sliding of the connecting seat (55) When the sleeve (551) is adjusted to the positioning hole (55〇) on the lower side of the rear link (54), the swing of the rear link (54) is reduced, and the height fluctuation of the pedal member is smaller than λ, and the pedal is made (56) h distance reduction with the pedal assembly (6〇)~ This can be used to match the user's leg length and use requirements, and appropriately adjust the span' to achieve improved comfort during exercise and training for improved service. The purpose of the effect. φ [Simple description of the diagram] The first diagram is a perspective view of the appearance of the side view before the creation. The second figure is a perspective view of the appearance of the side view after the creation. The third figure is a partial exploded perspective view of the present creation.
