In the above elliptical exercise machine, the second end of the second link has a positioning member ′ which is adjustable and positioned relative to the lower end of the second guiding mechanism. [Embodiment] Hereinafter, a preferred embodiment of the present invention and the achievable effects thereof will be described in detail with reference to the accompanying drawings. Referring to the first to fourth figures, the elliptical exercise machine (1) comprises a body (10) for being placed on a plane, the frame body (10) has a base (11), and the base (11) has a a first end and a second end, the first end is provided with a bracket (12). The bracket (12) is provided with an upwardly extending pole (13), and a top end of the pole (13) is fixed with a console (14). User-friendly. A first guiding mechanism (20) has two rails (21), each rail (21) has a first end and a second end, and the first end is respectively fixed to the second end of the base (11), and two rails ( 21) A fixing rod (22) is fixed between the second ends. a winding mechanism (30) having a rotating shaft (not shown), two cranks (31), a flywheel (32) and a pulley (33), the rotating shaft is disposed on the bracket (12), and the two cranks (31) Fixed on the two ends of the rotating shaft, and each crank (31) has opposite ends, one end of which is provided with a rewinding joint (34), which is rotatable relative to the rotating shaft, and the revolving joint (34) can be rotated in a circular path when rotating. On the movement. The flywheel (32) is pivotally mounted on the bracket (12) and can be rotated in situ relative to the crank (31). The pulley (33) is pivoted on the bracket (12), and the flywheel (32) and the pulley (33) are driven by a belt (not shown). The first connecting rods (40) each have a first end, a second end and a 200906462 struts, each of which is pivotally connected to the wrap-around joint (34), and each of the second ends is pivoted with a roller ( 41) 'When the rewinding joint (34) rotates relative to the rotating shaft, the roller (41) can be guided by the guide rail (21) to reciprocate on the guide rail (21). The support device is disposed between the first end and the second end. In this embodiment, the support device is a pulley (42) pivotally disposed on a side edge of the first link (40) and opposite to the first link. (40) Rotation in place. In addition, when the first end of the first link (4〇) moves along the circular trajectory and the roller (41) of the second end reciprocates on the guide rail (21), the pulley (42) is closed along an approximate ellipse. Track (T1) motion. A second guiding mechanism (50)' includes two handrails (51) pivoted on opposite sides of the pole (13) by a first pivot (52), respectively, for swinging relative to the pole (Μ). Each of the handrail bars (51) has an upper end portion (511) and a lower end portion (512). The upper end portion (511) forms a grip for the user to grasp; the lower end portion (512) is provided with a motor (53). A drive rod (54) and a second pivot (55), the motor (53) is electrically connected to the console (14) and can drive the drive rod (54) to move relative to the motor (53). In addition, when the handrail bar swings relative to the upright (13), the second pivot (55) reciprocates along an arcuate track. The second connecting rods (60) each have a first end and a second end, and the first end is provided with a positioning member " ' ----, Yue Yue, DU, and the skirt is changed to the lower end of the grab bar (51) The portion (512) is slidable relative to the grab bar (51) between an upper pole and a lower pole. The second end of the second link (6〇) is pivoted on the corresponding first link (40), and the pivot of the second end is pivoted with the pulley (42) of the side edge of the first link (4〇) Coaxially, when the pulley (42) moves along the aforementioned elliptical closed rail ^(Τ1), the second end of the second link (6 〇) is also synchronized along the closed trajectory (τ motion. 200906462 two support rods (70), respectively The pulley (42) is mounted on the pulley (42) of the first connecting rod (40), and is supported by the pulley (42). Each of the supporting rods (7〇) has a first end and a second end, and the first ends are disposed correspondingly. a second pivot (55) of the lower end portion (512) of the grab bar (51), and a second end branch-step (9) for the user to step on. Next, the use mode of the elliptical exercise machine (1) and the use thereof Efficacy, the following is an example of the above description of the upper pole and the lower pole. Please refer to the third figure 'not the slip sleeve (the 6〇 is positioned at the upper pole of the lower end (512) of the armrest 捍 (51). When the user operates the elliptical exercise machine (1), the pulley (42) moves along the closed trajectory (T1) while the support rod (7 〇) reciprocates on the pulley phantom. Due to the second pivot (55) The distance from the first yoke (52) is greater than the distance between the sliding sleeve (61) and the first pivot (52), so when the armrest cup (51) swings | the second drag axis (5) The moving distance is greater than the moving distance of the sliding sleeve (8), so that the moving distance of the pedal (71) is greater than the moving distance of the first end of the second connecting rod (60), whereby the elliptical exercise machine (1) can achieve the pedal stroke amplification The effect. Alternatively, the user can control the motor (53) to drive the drive rod (54) to move by operating the console (14) to move and position the sleeve (61) along the lower end portion (512) of the grab bar (51). The fourth figure shows that the sliding sleeve (Μ) is moved to the lower pole. The closed trajectory of the second end of the second connecting rod (6〇) before and after adjustment is unchanged, and the length of the second connecting rod (6〇) is also No change, so after the adjustment, the swinging amplitude of the handrail bar (5丨) is reduced, so that the running distance of the second pivotal illusion and the pedal (π) is small, and the stroke of the (four) plate (71) is larger. The closed trajectory (Τ21) is changed to a smaller closed trajectory (Τ22), whereby 200906462 can achieve the purpose of adjusting the foot movement stroke. Referring to the fifth figure, another embodiment is shown in the figure. Each of the tower poles (Π0) has a sliding slot (172). The first connecting rod (140) is provided with supporting means at the corresponding position, and the supporting device has A fixing bolt (143) is disposed in the sliding groove (172) to allow the support rod (170) to slide relative to the first link (140). The sixth figure shows another embodiment. The lower end portion (2512) of each of the armrest bars (251) of the elliptical exercise machine (2) is provided with a plurality of positioning holes (257), and each positioning member has a sliding sleeve (261) and a The positioning bolt (262) has a through hole, and the positioning bolt (262) is perforated through the sliding sleeve (261) and is disposed in the positioning hole (257). When the user needs to adjust the foot walking process, the positioning bolt (262) can be pulled out, then the sliding sleeve (261) is moved to the appropriate position, and the positioning bolt (262) is inserted into the sliding sleeve (261) perforation and positioning hole (257). Just fine. Finally, it should be noted that the elliptical motion machine shown in the above and the drawings is only a preferred embodiment of the present invention and does not limit the scope of the invention and the scope of the patent. In summary, the elliptical exercise machine of the present invention has an industrial value in addition to an increase in the foot movement stroke, the foot movement stroke of which can be adjusted by the user.
