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 can not 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.

The connecting rod (116) can be adjusted forward and backward relative 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 part (41) of the support rod (40) can be adjusted forward and backward along the base (11), and at the same time change the position of the third axis (A3) relative to the base, thereby changing the movement of the left and right stepping parts. For example, when the connecting rod (116) or the third axis (A3) is closer to the front end of the base (11), the movement trajectory of the stepping portion will tend to When the connecting rod (116) or the third axis (A3) is closer to the rear end of the base (11), the movement track of the stepping portion tends to be gentle, forming an oblique upward movement track. The adjustment mechanism of the third axis (A3) may also be a slide rail, that is, a longitudinal slide rail may be provided on the main rod (111) of the base (11), and the connecting rod (116) may be provided. A sliding seat is fixed on the slide rail, so that the connecting rod (116) can be slid on the main rod (111) to change the position of the third axis (A3), that is, change the left and right. The position of the pivoting part (41) of the two supporting rods (40) relative to the base (11) is to change the movement trajectory of the aforementioned left and right two pedals (52) to achieve different movement effects.
