Technical Field

The invention relates to sports equipment, in particular to sports equipment for leg sports.

Background

Fig. 1 and 2 show a publicly-known and used sports apparatus 90 (trade name: Matrix S-Force Performance Trainer) having a left swing arm 95L and a right swing arm 95R, each of which is swingable forward and backward according to a pivot a at a top end thereof corresponding to a left-right axial direction, and a left pedal 96L and a right pedal 96R are respectively provided at bottom ends of the left swing arm 95L and the right swing arm 95R, each pedal being displaceable along an arc trajectory T having the pivot a as an arc center in accordance with the swinging motion of the corresponding swing arm, each pedal being displaceable forward (simultaneously upward) at most to a position directly in front of the arc center and backward (simultaneously downward) at most to a position directly below the arc center based on a predetermined stop position, a linkage device (not shown) being provided between the two swing arms 95, 95R so that the forward swinging motion of one swing arm and the backward swinging motion of the other swing arm are mutually moved, and the two swing arms 95R are positioned at a balanced position (the left and right swing arms 96R) as shown in a side view of the left swing arm 95 and the left swing arm 96R, wherein the left swing arm 95 and the right swing arm are positioned at a balanced position (simultaneously as shown in a side view of the left swing arm 96R) and the left swing arm 96R, wherein the left swing arm.

As shown in FIG. 2, when the exercise apparatus 90 is used, the user U holds the handles 92 at the front end of the frame 91 with two hands, and steps on the left and

right pedals

96L, 96R, respectively, to alternately press down and lift up (simultaneously forward) the legs in opposite directions, and during the process, the user can control the movement of the feet by the movement of the two legs, such as making the

pedals

96L, 96R reciprocate approximately between the upper and lower positions shown in FIG. 2, or making the pedals turn back after descending to a lower position and ascending to a higher position, however, because the left and

right pedals

96L, 96R of the exercise apparatus 90 are displaced symmetrically and reversely with the balance position being fixed as the center, the movement stroke can be changed to some extent even though the relative angle between the upper pedal and the lower pedal is not changed, and the pedals are always displaced along the arc trajectory T between the front and the lower position of the arc center, the posture of the user is not changed substantially.

Furthermore, the exercise device 90 only provides the user with the leg exercise, and the user's hands and upper body are stable during the leg exercise and cannot move in cooperation with the lower body, so the exercise form and exercise effect are limited.

In addition, the pedals 96, 96R of the exercise apparatus 90 are pivotally connected to the bottom ends of the swing arms 95, 95R by a pivot (not numbered) corresponding to the left-right axial direction, respectively, and each pedal 96, L, 96R is naturally turned into a horizontal state with its top surface facing upward by its own weight when no external force is applied thereto (as shown in fig. 1), and each pedal 96, 96R follows the user's foot at any time during the reciprocating swing of the

swing arms

95L, 95R by the leg exercise described above, and is deflected with respect to the corresponding swing arm 95, 95R, keeping the top surface thereof in contact with the user's foot, however, since the swing arms 95, 95R are relatively deflectable at any angle (in an extreme, any position of the pedal on the circular arc trajectory T may be any angle), the user may have a feeling of swinging or leaning of the top surface of the pedal when performing the leg exercise, and accordingly, the rear end of the frame 91 of the exercise apparatus 90 is provided with a seat 93, so that the user may sit on the seat before performing the leg exercise, and may not stably perform the two steps on the seat 96, and may cause the user to perform the two steps on the seat 93, and may be directly, and may cause the two steps on the seat 93, and the foot, or the seat 93, and may be left and then, the foot may be left and right, and then, and may be left, and right, and then, and may be left.

member

150L, 150R to form a first pivotal connection (not labeled in the figures), and correspondingly, the front end is pivotally connected to the second swinging portion 162 of the corresponding second swinging

member

160L, 160R to form a second pivotal connection (not labeled in the figures), so that the first swinging

members

150, 150R and the second swinging

crank arms

182L and 182R are opposite to each other by 180 degrees around the axis of the crank shaft 181 (hereinafter referred to as the rotating axis).

A left connecting rod 190L and a right connecting rod 190R are connected between the rotating mechanism 180 and the left and right first swinging

members

150L, 150R, specifically, a first end (in this example, the front end) of each connecting

rod

190L, 190R is pivoted to the outer end of the

In another embodiment of the present invention (not shown), the stop portion may be disposed to limit the rotation range of the crank arm or the swing range of the first swinging member, so that the first end of the connecting rod can be displaced around the rotation axis as a circle center, but cannot completely surround the rotation axis; even so, each support part can still move along a circular arc or a reciprocating track similar to the circular arc, and the left and the right support parts are overlapped at a middle position on the reciprocating track. In addition, even if the first ends of the left and right links are not opposite to each other by 180 degrees around the rotation axis, the arrangement may be such that when one of the support portions is displaced forward from the intermediate position, the other support portion is displaced backward from the intermediate position.

It should be noted that, in the present invention, if the grip portion is provided to be swingable back and forth with the movement of the foot, it is not limited to providing the grip portion 163/164 on each of the second swing members 160L/260L and 160R/260R whose swing axes are fixed as in the first and second preferred embodiments, and it is noted that the present invention may also provide the grip portion on each of the first swing members whose swing axes are moved with the holder unit.

Fig. 12 shows a sporting apparatus 400 according to a fourth preferred embodiment of the present invention, which has the most obvious difference compared to the sporting apparatuses according to the previous embodiments, in that the second axle parts 461 of the left and right second swinging

members

460L, 460R in this embodiment are not directly pivoted on the frame 410, but pivoted on the holder unit 420 like the first axle parts 451 of the first swinging

members

450L, 450R, and the positions thereof relative to the frame 410 are changed along with the holder unit 420, specifically, the second axle parts 461 of the second swinging

Finally, referring to fig. 13, the exercise apparatus 500 of the preferred embodiment is similar to the conventional exercise apparatus 90 shown in fig. 2, wherein the left and right first swinging members 550L, 550R correspond to the left and right swinging arms 95L, 95R in fig. 2, and the top ends (the first axial portion 551) are pivoted on the bottom side of a seat 517, and the swinging motion of one of the left and right first swinging members 550L, 550R and the swinging motion of the other one of the left and right first swinging members are driven by a linkage mechanism (not shown) disposed inside the housing 518 under the seat 517, compared to the conventional exercise apparatus 90 shown in fig. 2, the exercise apparatus 500 of the preferred embodiment adds the left and right second swinging members 560L, 560R and the left and right second supporting members 570L, 570R, each of the second swinging members 560, 560R is pivoted on the frame 510 by the second axial portion 561, each of the supporting members 570 5, 570R is connected to the corresponding first swinging portion 562 and the second swinging portion 570, and then serves as a single swinging end 389 for a user to swing and provide a swing structure for a user to step on the top ends of the user, and provide a swing mechanism 387 for a user to get a step on the top end of the user's holding portion 387, and provide a user's holding portion 387 for a user's holding portion 387.
