  • the spinning axis 220 is disposed along the elongating direction of the shaft 21.
  • the first coiled section 221 and the second coiled section 222 are connected to each other along the spinning axis 220 of the wheel hub 22.
  • the cable 23 is coiled around the first coiled section 221 of the wheel hub 22 and has a first cable end and a second cable end.
  • the first cable end and the second cable end of the cable 23 are opposite to each other.
  • the first cable end of the cable 23 is fastened to the first coiled section 221 of the wheel hub 22 and is able to spin with the wheel hub 22.
  • the handle 24 is connected to the second cable end of the cable 23.
  • the two guiding rollers 25 are rotatably mounted to the cover 14. Each one of the two guiding rollers 25 has a rolling axis parallel to the spinning axis 220 of the wheel hub 22.
  • the second cable end of the cable 23 passes between the two guiding rollers 25 and then is connected to the handle 24.

  • the first pulley set 31 has at least one pulley.
  • the second pulley set 32 is connected to a bottom portion of the assembling mount 13 and is disposed at the second end of the beam 12.
  • the elastic cord 33 has elasticity and may be a flexible rope or even a combination of both a flexible rope and a cotton rope.
  • the elastic cord 33 is coiled around the second coiled section 222 of the wheel hub 22 and has a first cord end and a second cord end.
  • the first cord end and the second cord end of the elastic cord 33 are opposite each other.
  • the first cord end of the elastic cord 33 is stationary.
  • the first cord end of the elastic cord 33 is fastened to the second pulley set 32.
  • the first cord end of the elastic cord 33 may be optionally fastened to elsewhere.
  • the second cord end of the elastic cord 33 is fastened to the second coiled section 222 of the wheel hub 22 and is able to spin with the wheel hub 22.
  • the resistance assembly 40 is disposed adjacent to the rolling assembly 20 and has a tubular mount 41, an adjusting stick 42, a flywheel 44, and a resistance unit 43.
  • the tubular mount 41 is mounted to the cover 14.
  • the tubular mount 41 is disposed in the lengthwise direction of the beam 12 and extends into the cover 14.
  • the adjusting stick 42 is a threaded rod, is screwed with the tubular mount 41, and is movably mounted through the tubular mount 41.
  • the flywheel 44 may be made of a magnetic material.
  • the flywheel 44 is mounted to the shaft 21, is coaxially connected to the wheel hub 22 via the shaft 21, and is able to simultaneously rotate with the wheel hub 22.
  • the resistance unit 43 is pivotally connected to the tubular mount 41, and is connected to the adjusting stick 42.
  • the resistance unit 43 has multiple magnets and a brake pad.
  • the resistance unit 43 is driven by the adjusting stick 42 and is swingable toward the flywheel 44.
  • the handle 24 is pulled toward the first end of the beam 12.
  • the cable 23 connected to the handle 24 is pulled out from the cover 14 and is guided by the two guiding rollers 25. Since the cable 23 is coiled around the first coiled section 221 of the wheel hub 22 and the first cable end of the cable 23 is fastened to the first coiled section 221 of the wheel hub 22, the wheel hub 22 rotates along a counter-clockwise direction as shown in Fig. 7 . Then the elastic cord 33 is wound up on the second coiled section 222. Once the handle 24 is free from subjecting forces, the elastic cord 33 restores, the elastic cord 33 that is coiled around and fastened to the second coiled section 222 drives the wheel hub 22 to rotate along a clockwise direction as shown in Fig. 7 .
  • the cable 23 is wound up by the wheel hub 22, and the handle 24 connected to the cable 23 is drawn back toward the cover 14.
  • a user reciprocately pulls the handle 24 and is reciprocately drawn by the elastic cord 33 and the cable 23 to simulate the action of watercraft rowing.
  • the restoring force of the elastic cord 33 resists the user to pull the handle 24 and achieves resistance training.
  • the indoor rower in accordance with the present invention utilizes the restoring force of the elastic cord 33 to drive the wheel hub 22 to rotate and make the wheel hub 22 retract the cable 23.
  • the structure of the indoor rower in accordance with the present invention is simple, is convenient for assembling, and has the advantage of low manufacturing cost.
  • the resistance assembly 40 may be operated to adjust a training load of the indoor rower in accordance with the present invention.
  • the adjusting stick 42 mounted through the tubular mount 41 is able to move toward or away from the flywheel 44.
  • the adjusting stick 42 drives the resistance unit 43 to swing toward or away from the flywheel 44 to adjust a rotational speed of the flywheel 44.
  • the adjusting stick 42 extends into the cover 14 and pushes the resistance unit 43 to swing toward the flywheel 44.
  • the resistance unit 43 equipped with the magnets and the brake pad interferes with the rotating flywheel 44. Since the wheel hub 22 coaxially connected to the flywheel 44 via the shaft 21 is able to simultaneously rotate with the flywheel 44, the wheel hub 22 is difficult to rotate as well. Therefore, the user has to take more effort to pull the handle 24 to connect to the cable 23 that is coiled around the wheel hub 22.
  • a training load of the indoor rower in accordance with the present invention is enhanced.
