Therotary shaft 60 is journalled on thesupport plate 40 by means of a thrust bearing 77 and thebearing 762 so as to permit smooth rotation of theflywheel 75 relative to theplate 40. - The adjustable
magnetic resistance device 80 is disposed adjacent to theflywheel assembly 70 so as to provide resistance to rotation of theflywheel assembly 70, and includes apositioning seat 81, a threadedshaft 83, and amagnet seat 82. Thepositioning seat 81 is fixed on thesupport plate 40, and has two spaced-apart parallel slidingrails 811. The threadedshaft 83 is journalled on thepositioning seat 81, and has one end provided with ahand knob 831 to facilitate manual adjustment of the threadedshaft 83, and the other end formed with an externally threadedportion 832. Themagnet seat 82 includes a U-shapedbody 821 and two spaced-apart parallel slidingplates 822 that are connected fixedly to the U-shapedbody 821 and that are disposed respectively and slidably along the slidingrails 811. Thebody 821 has twoopposite side walls magnet units 825, between which theflywheel assembly 70 is disposed, and a connectingwall 826 which interconnects theside walls hole 8261 that engages the externally threadedportion 832 of the threadedshaft 83 so as to move the U-shapedbody 821 toward and away from theflywheel 75 when the threadedshaft 83 is rotated relative to thepositioning seat 81, thereby adjusting magnitude of the resistance. - Referring to FIG. 8, when performing a running exercise, the user's hands can grip the
fixed handles 30 so as to obtain suitable body support, thereby preventing accidents due to imbalance. When the user performs a treading exercise or jogging, the user's hands can pull thehandgrips 54 and move the foot and body portions accordingly. Due to the resistance provided by the spring members 526 (see FIG. 5) of the biasing units when thehandgrips 54 are pulled from the position shown in FIG. 6 to the position shown in FIG. 7, training of the user's forearms, stomach and leg muscles can be achieved, and functioning of the user's lungs can be improved, thereby effecting whole body exercise. Thus, the dual-function treading exerciser of the present invention does not only function as an ordinary treading exerciser, but also can provide training of the user's hand portion, stomach portion and leg portion and improve functioning of the lungs while permitting movement of the user's body in a comfortable and natural manner. - Referring to FIGS. 3 and 4, with regard to the operation of the biasing units, because each of the upper and
lower pulling devices rotary shaft 60 by means of theunidirectional bearing 53, when either of thehandgrips 54 is pulled rearwardly, thecorresponding pull cord 55 is unwound from thecorresponding pulley 52 such that thecorresponding pulley 52 rotates in a direction (A) (see FIG. 7) so as to rotate therotary shaft 60 and theflywheel 75 synchronously with thecorresponding pulley 52. Subsequently, upon release of thehandgrip 54, thecorresponding spring member 526 biases thecorresponding pull cord 55 to wind around thecorresponding pulley 52. At this time, thecorresponding pulley 52 rotates in a direction that is opposite to the direction (A) (see FIG. 7) so that rotation of thecorresponding pulley 52 cannot be transferred to therotary shaft 60 and theflywheel 75. - Referring to FIGS. 5 and 7, when the
handgrips 54 are pulled, due to the magnetic force applied on theflywheel 75 by themagnet units 825, thespring members 526 and themagnetic resistance device 80 provide cooperatively a relatively great resistance to rearward movement of thehandgrips 54 during exercise. Referring once again to FIG. 8, because themovable handle assembly 4 is disposed substantially higher than the fixed handles 30, when the user uses the pullingdevices handgrips 54 are pulled rearwardly and downwardly such that movement of thehandgrips 54 can train not only the forearm muscles, but also the stomach muscles. - Referring back to FIG. 5, when an increased load of exercise is desired, the
hand knob 831 is rotated so as to move themagnet seat 82 toward theflywheel 75 in a direction (B) in order to obtain a greater magnetic force. When themagnet seat 82 is moved away from theflywheel 75, as shown in FIG. 4, the magnetic resistance is reduced. - Referring to FIG. 9, the adjustable
magnetic resistance device 90 of the second preferred embodiment of the dual-function treading exerciser according to the present invention is shown to be substantially similar to the adjustable magnetic resistance device 80 (see FIG. 3) of the first preferred embodiment. However, in this embodiment, themagnetic resistance device 90 further includes amotor 91 and agear 93. The motor is disposed on thesupport plate 40, and is provided with amotor shaft 92. Thegear 93 is sleeved fixedly on themotor shaft 92, and engages the externally threaded portion of the threadedshaft 83 so as to transfer rotation of themotor shaft 92 to the threadedshaft 83. - The advantages of the dual-function treading exerciser of the present invention can be summarized as follows:
- 1. The dual-function treading exerciser of the present invention does not only have fixed
handles 30 to support the user during a running exercise, but also has amovable handle assembly 4 that can effectively train forearm, stomach, and leg muscles of the user and that can improve functioning of the user's lungs, thereby effecting exercise of the user's whole body. - 2. The design of the
movable handle assembly 4, which includes theflywheel assembly 70 and the adjustablemagnetic resistance device 80, enables the user to obtain a greater exercise effect. Furthermore, the presence of the upper and lower pullingdevices movable handle assembly 4 enables the user's hands to follow the body movement in a comfortable and natural manner. - 3. The
movable handle assembly 4 is disposed higher than the fixed handles 30 so as to train not only the forearm muscles, but the stomach muscles as well. - While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
