- Referring to the drawings and initially to FIGS.1-5, an exercising monocycle in accordance with a preferred embodiment of the present invention comprises a
main body 1, amain frame 10, amain shaft 20, anacceleration mechanism 30, and amagnetic control mechanism 40. - The
main body 1 is provided with aseat 1′ so that the user may be seated on theseat 1′ to ride the exercising monocycle. - The
main frame 10 is a substantially U-shaped frame that is secured on themain body 1. Themain frame 10 includes abottom plate 12 secured on themain body 1, and twoopposite fixing plates 11. Preferably, thebottom plate 12 is integrally formed with the twoopposite fixing plates 11. Each of the twoopposite fixing plates 11 is provided with abearing 13. One of the twoopposite fixing plates 11 is protruded with twoopposite support plates 14. - The
main shaft 20 is rotatably mounted in thebearing 13 of each of the twoopposite fixing plates 11, and has two ends each protruded outward from each of the twoopposite fixing plates 11 and each secured with acrank 21 which has apedal 22, so that themain shaft 20 may be rotated through thecranks 21 by stepping thepedals 22. - The
acceleration mechanism 30 is mounted in themain frame 10, and is driven by themain shaft 20, to output an acceleration power. - The
magnetic control mechanism 40 is mounted in themain frame 10, and includes aflywheel 41 for receiving the acceleration power output from theacceleration mechanism 30, and adamping device 45 for increasing the resistance of the entire system. Preferably, theacceleration mechanism 30 is mounted in theflywheel 41, and thedamping device 45 is a magnetic type damping device. - Thus, the user may be seated on the
seat 1′ to tread thepedals 22, thereby driving themain shaft 20 to rotate. Then, theacceleration mechanism 30 may be driven by rotation of themain shaft 20 to output an acceleration power to accelerate rotation of theflywheel 41. The rotation of theflywheel 41 is subjected to the resistance of thedamping device 45, so that the user has to provide a treading force to overcome the resistance of thedamping device 45, thereby obtaining an exercising effect. - The
acceleration mechanism 30 includes adrive gear 31 secured on and rotated by themain shaft 20, and a drivengear 32 rotatably mounted on themain shaft 20. A single direction bearing 320 is mounted on one side of the drivengear 32. Theacceleration mechanism 30 further includes asupport shaft 33 mounted on themain frame 10 and is parallel with themain shaft 20, and acomposite gear 34 rotatably mounted on thesupport shaft 33. Thecomposite gear 34 includes asmaller gear 340 meshing with thedrive gear 31, and alarger gear 341 meshing with the drivengear 32. Preferably, thedrive gear 31 has sixty teeth, the drivengear 32 has twenty teeth, thelarger gear 341 has sixty teeth, and thesmaller gear 340 has twenty teeth, thereby obtaining the optimum rotation ratio of 1:9. - The
flywheel 41 of themagnetic control mechanism 40 is mounted on the single direction bearing 320 that is mounted on one side of the drivengear 32. Theflywheel 41 of themagnetic control mechanism 40 is formed with anannular flange 42 which has an inner wall provided with ametallic layer 43. - The
flywheel 41 of themagnetic control mechanism 40 has a surface formed with multiple throughholes 44 each having one side protruded with anair guide plate 440 for introducing the ambient colder air through the throughholes 44 into the system when theflywheel 41 is rotated, and for carrying the heat produced by the magnetic resistance out of the system through the throughholes 44 when theflywheel 41 is rotated, thereby achieving the heatsink effect. - The
damping device 45 of themagnetic control mechanism 40 includes twoopposite support plates 46 each provided with multiplemagnetic blocks 460 which are spaced from theflange 42 of theflywheel 41 with a determined distance. Each of the twoopposite support plates 46 has a first end formed with apivot end 461 and a second end formed with afree end 462. Thedamping device 45 of themagnetic control mechanism 40 includes twopivot shafts 47 each extended through thepivot end 461 of each of the twoopposite support plates 46 and each secured on each of thesupport plates 14 of thefixing plate 11 of themain frame 10, so that thefree end 462 of each of the twoopposite support plates 46 may be pivoted about thepivot shaft 47. - Thus, the user may be seated on the
seat 1′ to tread thepedals 22, thereby driving themain shaft 20 to rotate, thereby rotating thedrive gear 31 which rotates thesmaller gear 340 which rotates thelarger gear 341 which rotates the drivengear 32 which rotates the single direction bearing 320 which rotates theflywheel 41. - Referring to FIG. 5, when the
flywheel 41 is rotated, themetallic layer 43 of theflywheel 41 is subjected to the magnetic force of themagnetic blocks 460 of the twoopposite support plates 46. Thus, the rotation of theflywheel 41 is subjected to the resistance of thedamping device 45, so that the user has to provide a treading force to overcome the magnetic resistance produced by the magnetic force of themagnetic blocks 460 of the twoopposite support plates 46 of thedamping device 45 of themagnetic control mechanism 40, thereby obtaining an exercising effect. - In general, the magnetic force of the
magnetic blocks 460 of thesupport plates 46 of thedamping device 45 of themagnetic control mechanism 40 may be changed, to change the magnetic resistance produced by the magnetic force of themagnetic blocks 460, so as to determine and change the user's exercising strength, that is, the range of consumption of the user's physical energy. - The exercising monocycle in accordance with a preferred embodiment of the present invention further comprises an adjusting
device 50 for adjusting the distance between themetallic layer 43 of theflywheel 41 and themagnetic blocks 460 of the twoopposite support plates 46, so as to change the magnetic force of themagnetic blocks 460 of thesupport plates 46 of thedamping device 45 of themagnetic control mechanism 40. - The adjusting
device 50 includes aseat plate 51, acontrol rod 52, aguide wheel 54, twocontrol wires 55, and twoelastic members 56. - The
seat plate 51 is secured on an upper portion of one of the two fixingplates 11 of themain frame 10, and is formed with a throughhole 510, andmultiple positioning recesses 511 surrounding the throughhole 510. - The
control rod 52 is passed through the throughhole 510 of theseat plate 51, and has an upper section secured with arotary knob 520, a mediate section provided with apositioning block 53, and a lower section extended into themain frame 10 and secured with a fixingblock 521. Thepositioning block 53 has a bottom formed with achamber 530 for receiving acompression spring 531 and apositioning ball 532 that may be locked in one of themultiple positioning recesses 511 of theseat plate 51, thereby providing a temporary positioning effect when therotary knob 520 is rotated. - The
guide wheel 54 is mounted on theseat plate 51, and is located adjacent to the fixingblock 521 of thecontrol rod 52. Theguide wheel 54 has a periphery formed withmultiple grooves 540. - Each of the two
control wires 55 has a first end secured on thefree end 462 of each of the twoopposite support plates 46 and a second end reeved through thegrooves 540 of theguide wheel 54 and secured on the fixingblock 521 of thecontrol rod 52. - Each of the two
elastic members 56 has a first end secured on theseat plate 51 and a second end secured on thefree end 462 of each of the twoopposite support plates 46. - When the
rotary knob 520 is rotated, thecontrol rod 52 may be rotated to rotate the fixingblock 521 which pulls thecontrol wires 55 through theguide wheel 54, so that thefree end 462 of each of the twoopposite support plates 46 may be pulled and moved by each of the twocontrol wires 55 from the position as shown in FIG. 5 to the position as shown in FIG. 6, thereby increasing the distance between themagnetic blocks 460 of the twoopposite support plates 46 and themetallic layer 43 of theflywheel 41, so that the magnetic force of themagnetic blocks 460 of the twoopposite support plates 46 on themetallic layer 43 of theflywheel 41 is decreased, and the magnetic resistance produced by the magnetic force of themagnetic blocks 460 is decreased. Thus, the user's exercising strength (or the range of consumption of the user's physical energy) is reduced. - On the contrary, when the
rotary knob 520 is rotated reversely, thecontrol rod 52 may be rotated to rotate the fixingblock 521 which releases thecontrol wires 55 through theguide wheel 54, so that thefree end 462 of each of the twoopposite support plates 46 may be pushed by the restoring force of each of the twoelastic member 56 to move from the position as shown in FIG. 6 to the position as shown in FIG. 5, thereby decreasing the distance between themagnetic blocks 460 of the twoopposite support plates 46 and themetallic layer 43 of theflywheel 41, so that the magnetic force of themagnetic blocks 460 of the twoopposite support plates 46 on themetallic layer 43 of theflywheel 41 is increased, and the magnetic resistance produced by the magnetic force of themagnetic blocks 460 is increased. Thus, the user's exercising strength (or the range of consumption of the user's physical energy) is increased. - Accordingly, the exercising monocycle in accordance with a preferred embodiment of the present invention has the following advantages.
- 1. The
main shaft 20 of the power input and theflywheel 41 of the power output are arranged in themain frame 10, so as to form a single-wheel type structure, thereby greatly reducing the volume of the exercising monocycle, so that the exercising monocycle occupies a smaller space. - 2. The
acceleration mechanism 30 includes multiple gears that may co-operate with each other, and the transmission ratio of the gears is not limited by the space and the wheel radius, so as to obtain a higher transmission ratio, thereby increasing the exercising effect. - Although the invention has been explained in relation to its preferred embodiment as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
