Thedetent wheels 31 are adapted to mechanically resist the rotation of the rotatingshafts 14. Eachflexible detent member 32 comprises adetent end 321 affixed to and wound round the outer perimeter of the associatingdetent wheel 31, aconnection end 322 connected to therear end portion 232 of one associatingpedal lever 23, and amiddle body portion 323 connected between thedetent end 321 and theconnection end 322 and is inserted through the U-shaped, tubulartop frame bar 131 of the supportingrack 13 and extended over the associatingpulley 132.

Further, the flexible linkingmembers 34 are respectively extended over therespective guide wheels 121. - The
vertical damping unit 40 is mounted in theframe 10 near theupright column 12 and drivable by thedriving unit 30 to impart a damping to thepedal levers 23 in response to the vertical vector Y. Thevertical damping unit 40 comprises abrake wheel 41 mounted at theupright column 12 of theframe 10, adriving wheel 42 mounted at thebottom frame member 11 at one side relative to thebrake wheel 41, atransmission member 43 connected between thebrake wheel 41 and thedriving wheel 42, acrankshaft 44 fixedly connected to thedriving wheel 42, and a pair ofguide wheels 45 respectively pivotally mounted at two opposite ends of thecrankshaft 44 in an eccentric manner relative to thedriving wheel 42. The flexible linkingmembers 34 are respectively extended over theguide wheels 45 for mechanically resisting the rotation of theguide wheels 45, driving thedriving wheel 42 to rotate and causing thebrake wheel 41 to produce a damping in response to the vertical vector Y. - Referring also to
FIG. 4 , the linking-upunit 50 comprises arocker arm 51 turnable back and forth relative to theupright column 12, a pair ofdrag members 52 respectively affixed to two opposite ends of therocker arm 51, and a pair oflinkages 53 respectively pivotally connected between the two opposite ends of therocker arm 51 and the linking-uprods 211 of thesleeves 21. - Referring also to
FIG. 4 , thehorizontal damping unit 60 comprises adamping wheel 61 pivotally mounted at theupright column 12 of theframe 10, and atransmission member 62 coupled between thedamping wheel 61 and thedrag members 52. Thedamping wheel 61 comprises agear 611. In this embodiment, thetransmission member 62 is a single-sided toothed bar meshed with thegear 611 and thedrag members 52. Using thesleeves 21 to drive therocker arm 51 to oscillate and to simultaneously move thedrag members 52 back and forth via the linking-upunit 50 can cause thetransmission member 62 to rotate thedamping wheel 61, imparting a damping to thepedal unit 20 in response to the horizontal vector X. - Referring also to
FIG. 3 , when the operator steps on thepedals 24 of the fitness equipment and alternately gives pressure to the twopedals 24 and the respective pedal levers 23 through two legs, theswing arms 22 and thehorizontal damping unit 60 are not movable. At this time, therear end portions 232 of thepedals 23 are respectively forced to drag the respectiveflexible detent members 32. Subject to the effect that thedetent ends 321 of theflexible detent members 32 are affixed to and wound around the outer perimeter of the respectivedetent wheels 31, and the effect that thedetent wheels 31 are respectively affixed to the rotatingshafts 14, theflexible detent members 32 mechanically resist the rotation of the rotatingshafts 14 relative to theframe 10. Further, when the rotatingshafts 14 are driven to rotate, they can drive the respective drivenwheels 33 to rotate. Subject to the effect that the drivenends 341 of the flexible linkingmembers 34 are respectively affixed to and wound around the outer perimeter of the respective drivenwheels 33, theflexible detent members 32 mechanically resist the movement of the flexible linkingmembers 34, and the flexible linkingmembers 34 mechanically resist the rotation of theguide wheels 45 and drive thedriving wheels 42 to rotate. This causes thebrake wheel 45 to generate a damping in response to the vertical vector Y, and thus the operator can train the muscles of the legs. - When the operator steps on the
pedals 24 and alternately gives a forward pressure to thepedals 24, in addition to the generation of the aforesaid damping in response to the vertical vector Y, thefront end portions 231 of the pedal levers 23 drive the bottom ends of therespective swing arms 22. Accordingly, theswing arms 22 alternately move therespective sleeves 21 back and forth relative to the respectiverotating shafts 14 and theframe 10. At the same time, the linking-uprods 211 of therespective sleeves 21 drive the respective linking-uprods 53 of the linking-upunit 50 to oscillate therocker arm 51 relative to theupright column 12, causing therocker arm 51 to move thedrag members 52 back and forth. Thus, thetransmission member 62 can be driven to rotate the dampingwheel 61 in generating a damping in response to the horizontal vector X, and the operator can therefore train the muscles of the legs. - Thus, the operator can operate the fitness equipment under different operating modes to generate: (1) damping in response to the horizontal vector X, (2) damping in response to the vertical vector Y, and (3) the combination of damping in response to the horizontal vector X and damping in response to the vertical vector Y. The present invention allows the operator to select different operating modes to meet different requirements, such as: the operating mode of forward-backward sliding, the operating mode of stepping up and down, and the operating mode of forward-backward and up-down elliptical trajectory.
- In conclusion, the present invention has the
rotating shafts 14 rotatably mounted between theupright column 12 and the supportingrack 13, and thesleeves 21 of thepedal unit 20 respectively and rotatably sleeved onto the rotatingshafts 14. This arrangement provides for simplifying the linking structure between thepedal unit 20 and the drivingunit 30, facilitating the installation process and reducing the number of component parts and the cost of equipment. - Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
