Description

Stepper with freely adjustable stride

The new model relates to a kind of fitness equipment, in particular to a stepper machine which can freely adjust the stride.

Referring to FIG. 1 , a conventional stepper includes a frame 11 , two swing frames 12 rotatably disposed on the frame 11 , and a plurality of weighted bars 13 disposed on the swing frames 12 . During use, the user simulates a running posture, steps on the swinging frames 12 backwards with both feet, and increases the resistance during the simulated running by the weight of the swinging frames 12 and the weighted bars 13, thereby increasing the Muscle strength required for running.

However, since the weight of the swing frames 12 and the weighted bars 13 is used to provide resistance, the gravity continues to act on the swing frames 12 and the weighted bars 13 during use. When the muscle strength is insufficient and the support is lost, the swing frames 12 and the weighted bars 13 will swing directly toward the user, resulting in insufficient safety. In addition, the existing stepper occupies a large space, and in order to provide resistance , the weight of the swinging frame 12 and the weighted bar piece 13 is relatively heavy, which causes the problem of being difficult to store when not in use.

Therefore, the purpose of the present invention is to provide a stepper with a freely adjustable stride that can improve safety and is easy to store.

The resistance unit includes a rotatable resistance member driven by the driving groups and providing resistance, and an adjustment group disposed on the rack unit and used for adjusting the resistance provided by the resistance member.

The rack unit can be switched between an unfolded state and a folded state. In the unfolded state, the rack unit is unfolded, and the transmission unit and the resistance unit can be actuated. In the folded state, the rack unit is folded And the occupied space is smaller than in the unfolded state.

The effect of the present invention is that the foot levers are freely swingable connected to the rack unit, and the resistance during movement is provided by rotating the pivot lever to link the rotatable resistance group instead of weight Therefore, the effect of improving safety can be achieved, and the rack unit can be switched between an unfolded state and a folded state, and in the folded state, the rack unit is folded and takes up less space than in the When unfolded, it is small to achieve the effect of easy storage.
