Description

Sports Equipment

The present invention relates to sports equipment, and more particularly to a sports equipment for leg exercises.

With the increasing popularity of sports today, people are gradually willing to set aside time for various sports when they are busy. However, due to the limited space of urban sports, and outdoor sports are often limited by weather conditions, indoor fitness has gradually emerged. Common indoor sports equipment for legs (lower body) include treadmills, exercise bikes, elliptical machines, slippers, steppers, etc. Except for treadmills, the above-mentioned various sports equipment are guided by movable pedals The user ’s feet are repeatedly moved according to a predetermined motion trajectory. For example, the pedals of the exercise bike are used to guide the cyclic movement of the feet on a circular trajectory, while the elliptical machine guides the biceps with an approximately elliptical trajectory. Foot movement and so on.

For a traditional stepper, it can only guide the pedals to perform up and down movements, so that the feet can move up and down, so that the muscles that can be trained are limited to the front and back local muscles of the legs, and cannot take into account the training of other lower body muscles. This makes the traditional stepper more limited in use and cannot meet the needs of users.

Angle, the present invention can pivot the pedal (52) at the rear end of the carrier arm (51) and the corresponding support rod (40), so that the pedal (52) can still be used when the pedal (52) is at a relatively high first turning point (P1) position. Maintaining an angle suitable for the user to step on, FIG. 7 illustrates that when the pedal (52) is at the first turning point (P1), the supporting rod (40) forms an angle (β) with respect to the horizontal. The included angle (β) is greater than the included angle (α) of the aforementioned pedal (52), that is, when the pedal (52) is located at a relatively high first turning point (P1), the deflection angle of the pedal (52) is smaller than the corresponding support The deflection angle of the lever (40), through the design of this structure, can enable the pedal (52) to be deflected at a small angle in use, so as to be closer to the movement track of the user when stepping on it. In addition, the pedal (52) of the present invention is fixedly connected to the rear end of the corresponding load arm (51) to form a stepping portion. The above embodiment illustrates that the support rod (40) is pivotally connected to the pedal (52), as shown in FIG. It is shown that the support part (42) of the aforementioned support rod (40) is pivotally provided at a pivot ear (523) corresponding to the bottom of the pedal socket (521), however, the support part (42) of the aforementioned support rod (40) can also be directly It is pivotally connected to the carrier arm (51) of the aforementioned carrier (50) to achieve the same purpose and effect.

Position, the lower connecting portion (62) of each of the aforementioned connecting rods (60) can be pivotably connected to any positioning hole (43) on the corresponding supporting rod (40), that is, through the aforementioned adjusting mechanism, each of the connecting rods The lower connecting portion (62) of (60) can adjust its distance from the third horizontal axis (A3) along the length direction of the corresponding support rod (40), and each of the aforementioned cranks (22) uses the first horizontal axis (A1) The orbit of the axis is fixed. By adjusting the distance of the lower connecting portion (62) of each link (60) relative to the third horizontal axis (A3), the swing of the left and right pedals (52) is changed. FIG. 9 is a schematic diagram showing the left and right two pedals (52) in a first use state, wherein the swing of the left and right two pedals (52) at the highest and lowest turning points is (θ1), 10 is a schematic diagram showing the left and right two pedals in a second use state, in which the lower connecting portions (62) of the left and right two links (60) are positioned closer to the aforementioned first use state. before On the positioning hole (43) of the third horizontal axis (A3), the swing of the left and right two pedals (52) at the highest and lowest turning points is (θ2), compared with the left and right two pedals (52) at the first The swing in the use state (Figure 9) and the second use state (Figure 10) can be compared to the angle of (θ2) is greater than (θ1), that is, when the lower connecting portion (62) of the connecting rod (60) is getting closer The third horizontal axis (A3) is pivotally positioned, and the swing amplitude of the two pedals (52) is larger, so that the user can freely adjust the swing amplitudes of the left and right pedals (52) to achieve different motion effects.

It is worth mentioning that the third horizontal axis (A3) of the present invention can also be set to be adjustable (not shown), that is, the aforementioned base (11) is used to pivot the aforementioned left and right support rods (40). The connecting rod (116) can be adjusted back and forth with respect to the base (11). In detail, the aforementioned connecting rod (116) can be movably fixed on the main rod (111) of the base (11). The pivoting portions (41) of the two supporting rods (40) can be adjusted forward and backward along the base (11), and at the same time change the position of the third horizontal axis (A3) relative to the base, thereby changing the left and right two pedaling portions. For example, when the connecting rod (116) or the third horizontal axis (A3) is closer to the front end of the base (11), the moving trajectory of the stepping portion will become steep; and when the connecting rod (116 ) Or as the third horizontal axis (A3) approaches the rear end of the base (11), the movement trajectory of the stepping portion becomes gentle, forming an oblique upward movement trajectory. The aforementioned adjustment mechanism of the third horizontal axis (A3) may also be a slide rail, that is, the aforementioned bottom The main rod (111) of the seat (11) can be provided with a longitudinal slide rail, and the aforementioned connecting rod (116) can be fixed on the slide rail through a slide seat, so the aforementioned connecting rod (116) can be attached to the main rod ( 111) Slide up and down to change the position of the third horizontal axis (A3), that is, change the position of the pivot portion (41) of the left and right support rods (40) relative to the base (11) to change The motion trajectories of the two left and right pedals (52) achieve different motion effects.

The above is only used to explain the preferred embodiments of the present invention, and is not intended to limit the present invention in any form. Therefore, any modification related to the present invention made in the same spirit of creation Or the changes, which are other forms that can be implemented and have the same effect, should still be included in the scope of the present invention.
