The pedals 41 are generated independently of each other, and the movements of the two are independent of each other, and the movements of the two pedals do not affect each other, and the operation of the entire structural system can be prevented from being damaged by the continued use of a certain component failure, and during maintenance. It can also be viewed only for faulty components, and has the advantage of easy maintenance and time saving.

Next, please refer to FIG. 6 , which is a second embodiment provided by the present invention, which differs from the first embodiment described above in that the length of the first link set 5 or the step 4 and the first The pivotal connection of the connecting rod set 5 is used to change the stroke of the upper and lower reciprocating displacement of the stepping rod 4, and at least one of the first cranking member 24 and the first transmission rod 51 is sleeved by an outer tube and an inner tube. And a positioning member is provided on the outer tube for positioning the inner tube relative to the outer tube, thereby adjusting the length of the first crank 24 or the first transmission rod 51, in this embodiment The first transmission rod 51 has the above-mentioned adjustment mechanism and is composed of an outer tube 51A, an inner tube 51B and a positioning member 51C. Further, one end of the stepping rod 4 is provided with a plurality of first pivoting portions 44 unequal to the first pivot 42 for the first transmission rod 5 1 Select to pivot to one of them.

In the actual use, as shown in FIGS. 7 and 8 , the first crank rod 24 can be rotated to drive the first transmission rod 51 by adjusting to reduce the length of the first transmission rod 51 . The swinging of the stepping lever 4 by the first pivot 42 as an axis can be increased, and the stroke of the pedal 41 up and down reciprocating displacement is increased.

The first transmission rod 51 can be pivotally connected to one of the first pivoting portions 44. The first transmission rod 44 has a different distance from the first pivot 42 and the first transmission rod The upper and lower displacements of the 51 by the first crank 24 are fixed, so that the pedal 4 is driven by the first transmission rod 51, and the first pivot 42 is pivoted, and the swing will be As the first transmission rod 51 pivotally changes the position of the stepping rod 4, as shown in FIGS. 9 and 10, the closer to the first pivot 42 the larger the swing of the stepping rod 4, the pedal 41 The longer the stroke of the up and down reciprocating displacement is.

Furthermore, as the second link set is disposed, at least one of the second crank 34 and the second drive rod 61 is sleeved by an outer tube and an inner tube, and is disposed on the outer tube. There is a positioning member for positioning the inner tube relative to the outer tube position, whereby the length of the second crank 34 or the second transmission rod 61 can be adjusted, as shown in FIG. 6 in the embodiment, the second The transmission rod 61 has the above-mentioned adjustment mechanism and is composed of an outer tube 61A, an inner tube 61B and a positioning member 61C. Further, one end of the pivoting rod 62 and the second transmission rod 61 is pivotally connected with a plurality of second pivoting portions 65 unequal to the pivoting portion 621, and the second transmission rod 61 is selectively pivotally connected to the second transmission rod 61. one of them.

The above adjustment mechanism is used in actual use, such as Figure 11 and Figure 12. As shown in the figure, when the second crank 34 is rotated to drive the second transmission rod 61 by adjusting the length of the second crank 34 or the second transmission rod 61, the pivot rod 62 can be increased. The pivoting portion 621 is a swing of the front and rear reciprocating pivoting of the shaft, so that the stroke of the reciprocating displacement of the pedal 41 by the pulling rod 63 is increased, and the pulling is selected by the third pivoting portion 45 provided on the pedal. The lever 63 is pivotally coupled to one of the members to change the distance the pedal reciprocates on the pedal.

The second transmission rod 61 can be pivotally connected to one of the second pivoting portions 65. The distance between the second pivoting portions 65 and the pivoting portion 621 is different, and the second transmission rod 61 is different. The upper and lower displacements are fixed by the second crank 34. Therefore, the pivot lever 62 is driven by the second transmission rod 61, and the second pivot 131 is pivoted. As the second transmission rod 61 pivotally changes the position of the pivot rod 62, as shown in FIGS. 13 and 14, the closer to the pivot portion 621, the larger the swing lever 62 swings. The longer the stroke of the pedal 41 for the reciprocating displacement of the pedal 41 is.

Finally, by the second resistance device of the exercise training machine, a combination of two sets of resistance values is provided, so that the control method of the double resistance which is different from the resistance value of the front and rear movement directions can be achieved in the present case, the first resistance device 2 and the The second resistance device 3 is disposed on the same side of a base frame 1; a second link group 6 has three pivot ends, and the first pivot end is pivotally connected to a pedal 41, and the second pivot end is pivoted Connected to the second resistance device 3, and the third pivoting end 621 is pivotally connected to the base frame 1, thereby allowing the second link group 6 to pivot on the base frame 1 and using the pedal 41 to move forward and backward. a second link set 6 for driving the second resistance device 3; a stepping rod 4 having one end connected by a first connection The rod set 5 is connected to the first resistance device 2, and the rod is pivotally connected to the base frame 1 at the ends of the rod, and the first link group 5 is driven up and down by the stepping rod 4 to drive The first resistance device 2 provides a dual resistance control method.

According to the structural details of the foregoing two embodiments, when the resistance value of the first resistance device is adjusted to a maximum value and greater than the resistance value of the second resistance device, the movements before and after are smoother, and the movements of the upper and lower sides are more limited. Therefore, similar forward and backward sliding steps can be simulated; conversely, when the resistance value of the first resistance device is adjusted to a minimum value and is smaller than the resistance value of the second resistance device, the movements before and after are more limited, and the movements of the upper and lower movements are smoother. Can simulate similar functions of up and down steps.

The second embodiment described above can be adapted to the user of different body members to adjust the member according to the step distance and the step height to change the stroke of the pedal in the up and down and back and forth reciprocating displacement, and has the advantages of human factors engineering.

However, the disclosure of the above-described embodiments is intended to be illustrative of the present invention and is not intended to limit the invention, and the replacement of equivalent elements is still within the scope of the invention.

From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objects and is in accordance with the provisions of the Patent Law.
