Abstract

This application relates to a step-up training device, including a base frame assembly, a support frame assembly, and a foot pedal. The base frame assembly is mounted on a bearing plane, and the support frame assembly is rotatably mounted on the base frame assembly. The support frame assembly has a pivot point rotatably connected to the base frame assembly and a shoulder support. The foot pedal is mounted on the base frame assembly, and the top surface of the foot pedal is used to create a height difference relative to the bearing plane for single-leg step-up training. During training, the user places one foot on the top surface of the foot pedal, extends the hip diagonally upward, and pushes against the shoulder support around the pivot point to perform step-up training. The trajectory formed by the shoulder support during the user's training is an arc-shaped trajectory, and the angle between the tangent of the arc and the plane where the foot pedal is located is an acute angle. By setting the angle between the tangent of the arc-shaped trajectory of the shoulder support and the plane where the foot pedal is located to an acute angle, this application makes the user's force direction diagonally upward, enhancing the stimulation of the gluteal muscles and reducing the impact on the knee and ankle joints.

Specifically, the legs of the user stepping on the pedal 5 are perpendicular to the top surface of the pedal 5, the body of the user extends obliquely upwards to the hip, the shoulder pushing portion 28 rotates around the turning point 29 to form an arc track, and the included angle between the tangent line of the arc track and the plane of the pedal 5 is an acute angle, so that the force-generating direction of the user in the pedaling training is the direction which is obliquely upwards away from the bearing plane.

The upward oblique force direction can make the hip of the trainer bend and stretch to a greater extent, and activate the hip muscles more effectively, so as to enhance the stimulating effect on the muscles and promote the training effect, and in addition, the upward oblique force direction can better disperse the body weight and training load, reduce the impact on knee joints and ankle joints, and reduce the risk of joint injury.

In some embodiments, the vertical distance of the point 29 relative to the bearing plane is a first distance, the vertical distance of the shoulder 28 relative to the bearing plane is a second distance, and the second distance is greater than the first distance in the initial position.

The initial position is the position of the shoulder portion 28 and the point 29 at this time when the user is not on the machine for training or when the user is not exerting a force after the user is on the machine. Wherein the position of the turning point 29 relative to the bearing plane is fixed, and the shoulder 28 rotates relative to the turning point 29 during training, and the position of the shoulder 28 relative to the bearing plane is always higher than the position of the turning point 29.

In some embodiments, the top surface of the pedal 5 is approximately parallel to the bearing plane, the pedal 5 is arranged on the underframe assembly 1 in a height-adjustable manner, the top surface of the pedal 5 is used for forming a height difference relative to the bearing plane, when the first distance is within a preset range, a user steps on the top surface of the pedal 5 with one foot, and the body extends obliquely upwards to push the shoulder lever 28 for stepping training.

It should be noted that the fact that the top surface of the pedal 5 is approximately parallel to the bearing plane means that there may be a case where the top surface of the pedal 5 is not parallel to the bearing plane, and in this case, the vertical distance from the center point of the pedal 5 to the bearing plane is taken as the height difference.
