In a preferred embodiment of the invention (not shown), the aforementioned guiding means may employ a conventional mechanism to provide a wraparound joint that can move around an elliptical, oval or other type of trajectory. In addition, the guiding device (12〇) can be connected to the 2 garments (not shown in the figure), so that the rewinding joint (123) must be turned into a force and force to rotate 'but this part is a conventional technique, and the present invention The association is not big. = The left and right sides of the exercise machine (10) each have a _most forward and a long section, and the front ends of the two support rods (130) each form a ^=(133), respectively pivoted The two windings a of the guiding device (12 〇) are moved, that is, restricted to the aforementioned circular trajectory (T1). The left and right sides of the ellipse == each have a longitudinally extending swing arm. Each swing arm (140) pivots a predetermined portion (hereinafter referred to as a splicing portion) (141) of the intermediate section to the skeleton. (10)), so that the top end and the bottom end can be opposite to each other with the pivot portion (14 ι) as the axis. The second swing arm (10) is slid into a grip (142) for the left hand and the user to grasp, and the bottom end (hereinafter referred to as a swing portion) (143) is pivotally connected to the two support rods (130), respectively. The upper portion is at a second portion (134) of the intermediate rearward position, whereby the second portion (134) of the guiding rod (10) is guided to move back and forth on the circular path of the aforementioned oscillating portion (10). The rear end of each support rod (13G) forms a stepping portion (g pedal) (135), and the H stepping portion (1 (6) is used to support the left and right feet of the user respectively. 9 200831161 By the above-mentioned basic structure 'When the user steps his feet on the aforementioned Erlang part (10)), and puts his hands on the front speed two grips (142), then pushes the support rods with both feet and hands. (130) and when the swing arm (140) is moved, the user's foot will move relative to the left and right two stepping portions (135) in an approximately elliptical "track, for example, ❾T2 in the figure", the hand The part also reciprocates back and forth along an arc track in reverse with the left and right grips (14 2). The elliptical exerciser (1〇〇) of this embodiment is characterized in that each support rod (130) ) is formed by joining a rod-shaped front piece (131) and a rod-shaped rear piece (]°32), and the two (131) (132) can move substantially along the long axial direction of the support rod (13〇). In this embodiment, the joint portion of the front piece (131) and the rear piece (132) is coaxially sleeved by a structure similar to a telescopic rod, and There is provided a maintaining device (not shown), and the foregoing maintaining device has a tendency to maintain a predetermined relative relationship between the front and rear members (131) and the rear member (132) even if the support rod is maintained for a predetermined length. When each other is to be separated from the aforementioned relationship 'including relatively close (ie, the support rod is shortened) and relatively far away (ie, the support rod is elongated), it is necessary to resist the predetermined resistance applied by the aforementioned maintaining means. For example, each of the maintaining means may employ two The group of magazines achieves the above-mentioned effects. The two springs are respectively connected between the front section (131) and the rear section (132), but the two are installed in opposite directions, and one of the tensions of the springs will be opposite to the front section (131). Pushing forward, the stretch of the other will push the front piece (131) relatively backward, so that the front piece (131) has a tendency to remain at a preset position relative to the rear piece (132), in other words, when When sufficient external force (one of the springs is compressed and the other spring is stretched), the front section (131) and the 200831161 rear section (132) will be correspondingly relatively close or relatively far apart, when the external force disappears or When the reduction is made, the front section (131) and the rear section (132) are inclined to restore the aforementioned preset relationship. In this embodiment, the swinging portion (143) of each of the swing arms (140) is pivotally connected to the support rod (130). The rear section (132) is forwardly positioned, in other words, the first portion (133) and the second portion (134) on each of the support rods (130) are located at the front section (131) and the rear section (132), respectively. on.

In addition, a spring (460) is disposed between the front end (451) of the connecting rod (45〇) and the swing arm (430), so that the front end (451) is maintained relative to the swing arm (43〇). The trend of a preset position. The above structure also allows the tread portion (4 41) to move on an approximately elliptical trajectory 'and 'when the user applies a force in the front-rear direction ± more than a certain degree, the front end (451) of the connecting rod (45G) is at the swing arm The position on (430) will be offset (ie, where - spring compression, another - elastic stretch), with the relative angle between the ^ ^ bone rod (44G) and the swing arm (10), so that the slider (10)) The stepping part (441) can be made further forward or backward. In this embodiment, the other-variant type can also achieve the same effect, that is, the front end of the rod (the front end of the _ (the predetermined position of the pivoting arm on the swing arm _ is shifted up and down; oppositely the 'sliding rods (side) The front end is changed to: enough = arm (10)) long axial slip way, pivoted on the coffee ^ track ί ί ru ru bottom. In this way, the movement of the treading portion (441) to the second reading length 'is also responded to the user's exertion force. 16 200831161 The front end of the connecting rod (450) and the front end of the sliding rod (440) on the swing arm (430) It is also possible to reverse the up and down. Finally, referring to the fifth preferred embodiment of the present invention shown in the eighth and ninth embodiments, the elliptical exercise machine (5〇〇) of the present embodiment mainly comprises: a skeleton (510); a guiding device (520), Referring to the ninth figure, in the present embodiment, the taxi guide I (520) has two mobile racks (521) (521)' that are juxtaposed side by side, and each can utilize the bottom roller (522) (522,) in the skeleton (510).
