Definitions

  • the present invention relates to fitness equipment and more particularly to a stair-climber with an adjustable inclination angle.
  • the present invention provides a stair-climber according to claim 1.
  • the sensor is disposed at the rear end of the second inclination unit to sense a user's feet on the multiple steps and send a sensing signal.
  • the control unit is electrically connected to the driving source of the step unit and the sensor to receive the sensing signal of the sensor and determine, with reference to a sensing result, whether to stop the driving source from operating.
  • the user adjusts the inclination angle of the inclination unit with the inclination unit regulator and then adjusts the angles of the steps with the step regulator such that the user can take exercise while treading on different climbing slopes with correct and comfortable postures.
  • the sensor is triggered to send a sensing signal to a control unit as soon as the user loses his or her footing, such that the control unit stops a driving source of the step unit from operating, thereby enhancing user safety.
  • a stair-climber 10 of the present invention comprises a base 20, a inclination unit assembly 25, an inclination unit regulator 50, a handrail unit 60, a step unit 70, a step regulator 80, a sensor 90, and a control unit 64.

  • the steps 75 are pivotally connected to the two chains 74 by a step shaft 752, such that the steps 75 are not only driven by the chains 74 to move cyclically but are also pivotally rotated relative to the second inclination unit 40 upward and downward.
  • the step unit 70 has a driving source 79.
  • the driving source 79 is mounted at the front end of the second inclination unit 40 and connected to one of the front sprockets 72 to thereby serve as a power source.
  • the step unit 70 further has a step adjustment frame 76.
  • the step adjustment frame 76 has two opposing lateral boards 77.

  • a guide slot 776 is disposed on the inner side of each lateral board 77.
  • the steps 75 are each connected to the lateral boards 77 by a guide rod 754.
  • a guide wheel 756 is mounted at each of the two ends of the guide rod 754.
  • the guide wheels 756 are rotatably inserted into the guide slots 776 of the lateral boards 77, respectively, to not only increase the stability of the recurring operation of the steps 75 but also allow the steps 75 to synchronize with the step adjustment frame 76.

  • the sensor 90 is mounted at the rear end of the second inclination unit 40 to sense a user's feet on the steps 75.
  • the sensor 90 is exemplified by an optical breaker and comprises a light-emitting component 92 and a light-receiving component 94. Any break in the light path between the light-emitting component 92 and the light-receiving component 94 indicates that the user's foot is incorrectly placed on a step, and thus the sensor 90 sends a sensing signal.

  • the handrail rods 63 and the movable upright rods 61 enable the user to adjust the handrail rods 63 to an appropriate position with reference to the inclination angle of the second inclination unit 40.
  • the present invention is characterized in that: the second motor 81 is started, such that the second bolt 82 is driven by the second motor 81; the second sleeve 83 pulls the linkage unit 88 to thereby not only drive the two slide tables 87 to slide forward along the rails 86 but also pull the bottom end of the linkage arms 89, such that the second pivot P2 moves forward along the limiting slot 42 of the second inclination unit 40, thereby allowing the linkage arms 89 to deflect; during the deflection of the linkage arms 89, the top ends of the linkage arms 89 pull the step adjustment frame 76 downward, such that the step adjustment frame 76 moves downward relative to the second inclination unit 40; during the movement of the step adjustment frame 76, due to the relation between each lateral board 77 and a corresponding one of the guide wheels 756, the steps 75 each rotate pivotally relative to the second inclination unit 40 such that the steps 75 are each oriented at a specific angle, for example, oriented horizontally or oriented at
