Description

  The present invention relates to an exercise device, and more particularly to a stepping exercise machine.

  A stepping exerciser is an exercise device that increases heart rate, burns calories, and increases cardiopulmonary function.

  However, in the conventional technique described above, that is, in the design of the conventional stepping exercise machine, the user stands on two pedals having a predetermined resistance force, and the pedals are changed so as to climb the stairs by putting force on both feet. Repeatedly stepping up and down with this, train the thigh and buttocks muscles. Compared to a running machine, a stepping exercise machine has a smaller impact force on the thigh, but it must be used with care so as not to injure the knee.

  1A and 1B show the structure of two types of conventional stepping exercise machines and the movement trajectory of the pedals. FIG. 1A shows the structure of the fixed shaft portion single connecting rod, and FIG. 1B shows the structure of the fixed shaft portion two connecting rods. The pedal 20 is fixed to the connecting rod 22, one end of the connecting rod 22 is connected to the shaft portion 21, the pedal movement locus P has an outer arc shape, and the center indicates a direction away from the user. This motion trajectory does not match ergonomics and cannot simulate actual stepping, walking, mountain climbing, or the like.

  For example, in the stepping exercise machine described in Patent Document 1, a crank arm applies a force to a swing arm, and a connecting rod (pedal link) connected to the swing arm is moved back and forth. The connecting rod has a roller anti-friction member that is pivotally connected to a pedal. When the connecting rod moves forward, the pedal is interlocked by the roller and moves upward and diagonally forward along the ramp rod. In the above-described structure, the thrust for raising the pedal is insufficient, and an actual stepping, walking, or mountain climbing exercise cannot be simulated. The adjustable stepping exercise machine disclosed in Patent Document 2 and the stepping exercise machine disclosed in Patent Document 3 are both proposed patent applications.

  In addition, the stepping exercise machine according to the prior art cannot adjust the stride size according to each user.

  In addition, in the stepping exercise machine according to the prior art, the pedal slides along a limited trajectory and generates an abnormal noise.

  Regarding the stepping exercise machine according to the prior art, refer to patent application proposals such as “Adjustable stepping exercise machine” in Patent Document 2 and “Stepping exercise machine” in Patent Document 3.

To do. In addition, when a force is directly applied to the footrest support pipe 12 by the crank 14, the disadvantage that the upward thrust is insufficient with the conventional technology pedal is improved, and the pedal movement locus Pb conforms to ergonomics. Get closer to the actual stepping, walking or climbing exercise. In addition, the pedal movement trajectory Pb is very smooth, which increases the comfort of use and eliminates the “hook”. The so-called “hook” is a feeling of stagnation that the user feels when stepping on. In addition, the exercise apparatus 1 according to the embodiment of the present invention does not require a slide tube, and the generation of noise due to the contact of the slide tube during the movement of the pedal 16 is avoided.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
