    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to FIGS. 3 to 5, the elliptical exerciser 1 of the present invention comprises a frame 10 with a wheel 20 connected thereto and two swinging mechanisms 40 are pivotably connected on two sides of the wheel 20. A post is connected to the frame 10 and a control panel 11 is connected to a top of the post. Two handles 12 are located in front of the control panel 11. Each swinging mechanism 40 includes a swing bar 41 which has a mediate portion 411 pivotably connected to two pivots 13 on two sides of the post. Two connection links 42 each have a first end 422 pivotably connected to the wheel 20 and a second end of each connection link 42 is connected to an adjusting mechanism 30 by two connection bars 32. Two pedals 43 are connected to the connection links 42 and two connection rods 421 are connected between the lower ends of the swing bars 41 and the support of the pedal 43.
  • The adjusting mechanism 30 including a main body 31 which is an H-shaped member and includes two lower ends 311 at a first end of the main body 31 pivotably connected to two first lugs 14 on the frame 10 by two bolts 51. Two upper ends 312 of a second end of the main body 31 are bent toward the wheel 20 and are pivotably connected to two respective first holes 321 in two respective first ends of the two connection bars 32 by two bolts 52. Two respective second holes 322 are defined in two respective second ends of the two connection bars 32 and the two respective second ends of the connection links 42 are pivotably connected with the second holes 322 by extending two pins 53 through the second holes 322, the second ends of the connection links 42 and tow respective pivotable members 322. The main body 31 includes two transverse bars and one of the transverse bars has a second lug 313. A retractable device 33 is connected between the adjusting mechanism 30 and the frame 10.
  • The retractable device 33 includes a motor 331, a threaded rod 332 and a sleeve 333. The motor 331 is fixed on the frame 10 and includes an output portion 3311 and the threaded rod 332 is retractably connected to an output portion 3311 of the motor 331. The sleeve 333 is connected to the threaded rod 332 and pivotably connected to the second lug 313 on the main body 31. The sleeve 333 moves when the threaded rod 332 is rotated.
  • As shown in FIG. 6, the user can activate the motor 331 by operation on the control panel 11 so as to retract the threaded rod 332 so that the main body 31 tilts 14 degrees from the position in FIG. 5 where the main body 31 is perpendicular to the frame 10. Referring to FIGS. 7 and 8, when the two respective first ends 422 of the connection links 42 are moved to two opposite ends of the wheel 20, an angle of 10 degrees is defined between the two connection links 42 when the main body 31 is perpendicular to the frame 10, and an angle of 1 degree is defined between the two connection links 42 when the main body 31 is pivoted 14 degrees from the position in FIG. 7. An angle between the two connection bars 32 is 55 degrees when the main body 31 is pivoted 14 degrees. In the position of FIG. 8, the distance between the two pedals 43 is reduced and the long and short axes of the oval track of the pedals are also changed.
  • FIGS. 9 and 10 show another embodiment of the adjusting mechanism 30 wherein the retractable device 33 is a substantially T-shaped device and one end of a rod 34 of the retractable device 30 is connected to the second lug 313. The other end of the rod 34 includes a transverse shaft 342 and two rollers 54 are connected to two ends of the shaft 342. The two rollers 54 are movable on two rails 15 on the frame 10. A pivotable member 343 is connected to a mediate portion of the rod 34 and pivotably connected to the sleeve 333 of the retractable device 33. The sleeve 333 is connected to the threaded rod 332 and pivotably connected to a third lug 341 of the rod 34. The sleeve 333 moves when the threaded rod 332 is rotated.
  • As shown in FIG. 11, when the motor 331 is activated, the threaded rod 332 is rotated so that the sleeve 333 is moved to pull the main body 31 toward the wheel 20, and the rollers 54 move along the rails 15. When the main body 31 is positioned as shown in FIG. 10, the long axis of the oval track of the pedals 43 is an inclined oval. When the main body 31 is pivoted angle as disclosed in FIG. 11, the long axis of the oval track of the pedals 43 is adjusted to be close to a horizontal line.
  • While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
