  • Indoor exercisers are popular in modem societies by providing exercising effects without going to the outside. The exercisers also provide rehabilitation functions for patients or people having difficulty in getting about.
  • A pedal exerciser generally includes a pedaling device providing a pedaling function like a bicycle and a mat on which a user can sit or lie while proceeding with pedaling with his or her hands or legs. However, adjustment of the height of the pedaling device is inconvenient to the user and is difficult to patients or people having difficulty getting about.
  • Some of currently available pedal devices allow adjustment in the resistance to rotational movement by using magnetic control or a damping mechanism. The damping mechanism increases the overall weights of the pedaling devices and increases the difficulty of height adjustment.

    •  DETAILED DESCRIPTION OF THE INVENTION
  • With reference to FIGS. 1-5, a pedal exerciser according to the present invention includes a base 1, a pedaling device 2, and a height adjusting mechanism 3. The base 1 is adapted to be located on the ground. The base 1 includes a seat 11 on a rear end thereof. A user can sit or lie on the seat 11 while using the pedal exerciser. An engagement portion 12 is provided in front of the seat 11 and includes a coupling tube 13 extending substantially vertically from a bottom of the base 1. The coupling tube 13 can be fixed to the base 1 or adjustable to change a relative angular position between the coupling tube 13 and the base 1. The coupling tube 13 includes a coupling hole 131 and a first notch 132 extending vertically and in communication with the coupling hole 131.
  • The pedaling device 2 is adapted to be rotated by legs or hands or the user. The pedaling device 2 includes a column 21 on a lower portion thereof. The column 21 includes a rack 22 having a toothed portion 221. The column 21 is received in the coupling hole 131 of the base 1. The rack 22 is received in the first notch 132, and the toothed portion 221 extends outside of the first notch 132.
  • The height adjusting mechanism 3 includes a motor 31, a sleeve 32, and a coupling seat 33. The motor 31 is adapted to be controlled by a controller. The height adjusting mechanism 3 further includes a reduction gear box 311 having an output shaft 312 driven by a rotating shaft of the motor 31. A transmission gear 313 is mounted on the output shaft 312 and meshes with the toothed portion 221 of the rack 22. The sleeve 32 receives the column 21 and has a bottom portion received in the coupling hole 131 of the base 1. The sleeve 32 further has a second notch 321 receiving the rack 22. The coupling seat 33 is mounted around an upper portion of the sleeve 32. The coupling seat 33 includes a coupling section 330 coupled with the reduction gear box 311. The coupling section 330 includes a compartment 331 having an opening 3311 facing the second notch 321. Transmission gear 313 is rotatably received in the compartment 331. The coupling seat 33 further includes a third notch 332. The coupling seat 33 further includes a first tightening bolt hole 333 in a location corresponding to the opening 3311 of the compartment 331 and a second tightening bolt hole 334 in a location corresponding to the third notch 332. First and second tightening bolts 335 and 336 are mounted in the first and second tightening bolt holes 333 and 334.
  • The column 21 of the pedaling device 2 is extended through the sleeve 32 and the coupling hole 131 of the coupling tube 13 of the seat 1. The transmission gear 313 meshes with the rack 22 via the opening 3311 of the compartment 331.
  • With reference to FIGS. 6 and 7, the motor 31 is operable to drive the output shaft 312 to move the rack 22 in a vertical direction via the transmission gear 313. Thus, the pedaling device 2 is moved in the vertical direction, providing convenient adjustment of a height of the pedaling device 2 in the vertical direction. After adjustment, the first and second tightening bolts 335 and 336 can be rotated such that the sleeve 32 clamps and tightens the column 21. The second and third notches 321 and 332 and the opening 3311 of the compartment 331 provides room for deformation of the sleeve 32 clamping the column 21, providing reliable positioning.
  • The pedal exerciser according to the present invention allows easy adjustment of the height of the pedal device 2 by providing the height adjusting mechanism 3, which is suitable for patients or weak users. The motor 31 can be mounted to a side of the column 21 through other provisions with the transmission gear 313 meshed with the rack 22.
  • Although specific embodiments have been illustrated and described, numerous modifications and variations are still possible without departing from the essence of the invention. The scope of the invention is limited by the accompanying claims.
