Movement track. In detail, although the auxiliary swing arm and the base are pivoted in the front opening patent, the shaft joint only allows pivoting without the function of height or horizontal position adjustment. The trajectory adjusting mechanism of the present invention gives a height adjustment function to the shaft contact point (the pivot joint 40) of the auxiliary swing arm 930 and the base 911, and thus changes the pivot joint of the pivot joint 40 to the auxiliary sliding sleeve 931 and the rotating link 941. The distance between the sub-sliders 931 and the fulcrum pivoted relative to the rotating link 941 is connected to thereby change the trajectory generated by the pedal 9224.

Referring now to the fourth figure, which is a side view of the trajectory adjustment mechanism of the present invention, wherein the drive source 30 is not activated, the trajectory adjustment mechanism is in the first position. In the first position, since the driving shaft of the driving source 30 is folded, the distance between the inner ends of the L-shaped components 11 and 21 is the shortest, so the connecting portions 15 and 25 are pivoted downward to present a relative folding. The positional relationship causes the slides 13, 23 pivoted to the outer ends of the L-shaped members 11, 21 to be in the highest position, and the pivotal seats 40 are also located at the highest position.

The fifth figure is the movement track O1 generated by the link type sports equipment when the track adjustment mechanism is in the first position and the pivotal support 40 of the track adjustment mechanism is at the highest position.

In the second position, since the driving shaft of the driving source 30 protrudes from one half of the stroke thereof, the distance between the inner ends of the L-shaped members 11 and 21 is relatively pushed away, so that the connecting portions 15 and 25 are pivoted upward. Turning, the distance is longer than the fourth figure, that is, the relative positional relationship, so that the slides 13, 23 pivoted to the outer ends of the L-shaped components 11, 21 are lowered, and the pivotal seats 40 are middle place.

The seventh figure is the movement track O2 generated by the link type sports equipment when the track adjustment mechanism is in the second position and the pivotal support 40 of the track adjustment mechanism is in the intermediate position.

As shown in the eighth figure, which is a side view of the trajectory adjustment mechanism of the present invention, wherein the drive source 30 is activated and stopped at the full stroke position, so that the trajectory adjustment mechanism is in the third position. In the third position, since the driving shaft of the driving source 30 completes its stroke, the connecting portions 15, 25 continue to pivot upward, so that the innermost end of the L-shaped members 11, 21 is the longest, that is, the present The fully deployed positional relationship causes the sliders 13, 23 and the pivoting seat 40 pivotally connected to the outer ends of the L-shaped members 11, 21 to descend to the lowest position.

The ninth figure is the movement track O3 generated by the first type of link sports equipment when the track adjustment mechanism is in the third position and the pivotal support 40 of the track adjustment mechanism is at the lowest position.

It can be seen from the figure that due to the change of the position of the slides 13, 23, the link type sports equipment does generate multiple movement trajectories such as O1, O2 and O3, so that the user is provided with training of different muscle groups or different difficulty levels. However, it should be noted that the trajectory adjustment mechanism of the present invention utilizes the feature that the drive source 30 (ie, the linear actuator) is disposed at the center of the mechanism, and can effectively drive the pivots of both sides of the link sports equipment with a single drive source. The socket 40 not only improves the reliability of the mechanism, but also reduces the structural complexity, and also provides stepless track adjustment. In other words, in the embodiment, the movement track of the rod type sports equipment is not limited to O1, O2 and O3 shown in the figure, but can be arbitrarily adjusted according to the stroke of the drive shaft of the actuator 30, The same link-type sports equipment has an infinite track change.

In addition, the trajectory adjusting mechanism of the present invention does not cause the problem that the sliding seats 13 and 23 are unevenly displaced or the mechanism is unevenly biased, so that the heights of the auxiliary swing arms 930 on both sides of the sports equipment and the base 911 can be ensured to be the same height. In order to avoid the user's unbalanced tilting movement, the safety of the movement is ensured, and the uneven force of the mechanism can be avoided, resulting in a problem of failure after long-term use. Moreover, the trajectory adjustment mechanism of the present invention only needs a single driving source to achieve the function of changing the height of the auxiliary swing arm 930 on both sides of the sports equipment and the base 911 shaft contact point, and eliminating the need to set a driving source 30 on both sides, so Economic advantage.

Furthermore, as shown in FIG. 11 , in addition to adjusting the height of the pivoting seat 40 by the trajectory adjusting mechanism to adjust the motion track generated by the link type sports equipment, the present invention can further adjust the pivot. The horizontal position of the socket 40 is adjusted to adjust the elevation angle of the motion trajectory. For example, a sliding seat 50 and a sliding rail 51 can be disposed between the trajectory adjusting mechanism and the base 911. The trajectory adjusting mechanism can be used by the sliding seat 50. A horizontal slip is generated on the sliding rail 51 to drive the pivoting seat 40 to generate a horizontal position adjustment, and the trajectory adjusting mechanism can be slidably adjusted on the sliding rail 51 by means of manual or power source driving, and Lock and fix again after adjusting to the appropriate position. When the pivotal point of the main swing arm 920 and the bracket 912 and the pivotal point of the auxiliary swing arm 930 and the base 911 are changed, the elevation and elevation of the motion path of the link sports equipment may be generated. The angle changes.
