Definitions

  • the present invention relates to the field of physical exercising or fitness equipment, and in particular to an elliptical track exercising device having a reduced volume and effectively increasing exercising amount.
  • FIG. 1 of the attached drawings shows a conventional vane-type stationary bicycle, which comprises a home or chassis 10 that stands on the ground.
  • a vane assembly 11 for inducing a wind resistance is mounted on the frame 10 .
  • the vane assembly 11 is driven by a crank assembly 12 that is arranged in the rear portion.
  • the crank 12 are provided at opposite sides thereof two pedals 13 that are provided with linking bars 14 .
  • Handgrips 15 which can rock back and fro, are provided at opposite sides of a front end of the frame 10 . Lower ends of the handgrips 15 are respectively pivoted to the linking bars 14 of the pedals 13 to form driving coupling therebetween.
  • a central portion of the frame 10 is raised upward and is provided with a seat assembly 16 , whereby a user may sit on the seat assembly 16 and treads the pedals 13 with hands holding and rocking the handgrips 15 back and fro. Since the pedals 13 are directly coupled to the center of the crank assembly 12 , they just undergo rotation along circular tracks. This means the amount of exercise is less.
  • the seat assembly 16 and the handgrips 15 are must for the known device and this means it is in general not possible to significantly reduce the overall volume of the device, which leads to troubles in storage and transportation.
  • FIG. 2 is a magnetism-controlled track exercising device, comprising an I-shaped base 20 having a front end on which a suspension frame 21 is provided.
  • a magnetism control wheel set 22 and a crank set 23 are respectively arranged at front and rear sides of the suspension frame 21 .
  • Pedals 24 are respectively located on opposite sides and rear ends of the pedals 24 are rotatably connected to the crank set 23 so as to induce motion along an elliptic track, which helps increasing the amount of exercising.
  • handgrips 25 are located on opposite sides of and are pivotally coupled to the front end of the suspension frame 21 .
  • FIG. 3 which illustrates a dual-crank type track exercising device, comprising a chassis 30 having a front section on which a suspension frame 31 is arranged.
  • a flywheel set 32 is arranged in the suspension frame 31 and has crank arms 33 on opposite sides thereof.
  • the chassis 30 is provided at a rear section thereof with a crank set 34 that drives the flywheel set 32 .
  • Pedals 35 are arranged on opposite sides of the crank set 34 .
  • a link 36 is connected to a front end of each pedal 35 and is also connected to the respective crank arm 33 , so that the pedals 35 can reciprocate back and fro between the crank arms 33 of the flywheel set 32 and the crank set 34 .
  • handgrips 37 are provided at front end of both the suspension frame 31 and the chassis 30 to be held by the rider.
  • the crank arms 33 and the crank set 34 are rotated to the topmost positions, the pedals 35 have the gravity centers thereof located at very high position whereby without holding the handgrips 37 , the rider may be subject to high potential of risk.
  • the handgrips 37 are a must for the known device.
  • FIG. 4 of the attached drawings illustrates a slide type track exercising device, comprising a chassis 40 and a vertical post 41 is arranged at a rear end of the chassis 40 .
  • a crank set 42 is rotatably mounted to a top end of the post 41 .
  • a guide tube 44 which carries a pedal 43 , is provided at each side of the crank set 42 .
  • the guide tube 44 contains therein a compression spring is in telescopic connection with a slide bar 45 that is pivoted to the chassis 40 .
  • FIG. 5 illustrates a further conventional slide type track exercising device, which comprises a chassis 50 having a rear end to which a crank set 51 is mounted and a flywheel set 52 is arranged in front of and in driving coupling with the crank set 51 .
  • the flywheel 52 provides resistance to effect exercising.
  • a handgrip post 53 is erected at a front end of the chassis 50 .
  • a guide bar 54 is provided at and pivoted to opposite sides of a lower section of the handgrip post 53 and a slidable pedal 55 is slidably mounted on each guide bar 54 .
  • the slidable pedal 55 is pivoted at a rear end thereof to the crank set 51 so that when the crank set 51 is rotated, the slidable pedals 55 slide along the guide bars to effect the greatest extent of track exercising.
  • the pedals 55 are not fixed with respect to the guide bars 54 and thus the handgrip post 53 is a must for the user to keep balance.
  • the overall volume cannot be reduced, leading to the same problems of storage, use,
  • the known pedaling type track exercising devices provides the users with exercising by pedaling action. Since in all the known devices, the support point or fulcrum and the pivot point are “floating” rather than stationary, when the device is operated to take track motion, the gravity center of the pedals are located in front of the user so that the user cannot control the balance thereof and thus handgrips located in front of the chassis are required to support the user.
  • the known sliding type uses the slidable pedals sliding along the guide bars to realize exercising. Again, since the pedals are “floating” and are not properly supported, when the device is operated to take track motion, the user is not able to control balance so that again, handgrips are needed in the front of the chassis for supporting the user.
  • the conventional pedaling type track, exercising devices realize exercising by pedaling action.
  • a large size vane is needed.
  • crank set and chain are used to drive the vane. All these complicate the construction and enlarge the overall volume.
  • the gravity center is put at a high altitude, causing negative effect on the operation safety.
  • the handgrips that allow the user to keep balance also increase the overall volume of the track exercising device, causing problems in flexibility of space use and inconvenience of use, installation, storage, and transportation.
  • the primary purpose of the present invention is to provide a miniaturized track exercising device, which has reduced overall volume and has enhanced operation safety.
  • a miniaturized track exercising device comprises a chassis on which a counterweight wheel set is provided.
  • the counterweight wheel set is provided with a resistance adjusting unit for adjusting the resistance induced by the counterweight wheel set.
  • Two crank arms extend in opposite directions and are arranged on opposite sides of the counterweight wheel set. Each crank arm is pivotally connected to a pedal in an offset manner.
  • the pedals are provided with a guide rail unit that is opposite to the crank arms with respect to the pedals and that provides a pivot joint and a fulcrum.
  • the present invention may adjust the resistance against the rotation of the counterweight wheel set by means of the resistance adjusting unit and the guide rail unit, provides support against gravitational force acting on the pedals while the pedals undergo track motion, so that the user may stably stand on the pedal to take the track motion without the handgrips to maintain balance.
  • reduction of overall volume and putting the gravity center at a lower altitude are realized. And, exercising result can also be enhanced with safety.
