Description

adjustable stepper

technical field

The utility model relates to a stepper body-building exercise equipment, in particular to an adjustable stepping amplitude exercise equipment.

Background technique

The original sports equipment is a monotonous, fixed-range stepping exercise method, and its disadvantage is that the user must exercise with a fixed stepping range when stepping on it. And use a pneumatic cylinder or hydraulic cylinder as a damper. When the user steps on the left foot at the beginning, it takes a lot of effort to leave the top dead center and step on it to the bottom dead point. At the beginning of the right foot, it must take a lot of effort to leave the top dead point to move to the bottom dead point, and the bottom dead point will produce a pause. This kind of pause and the force application state at the beginning of pedaling are burdens on the knees of elderly users or long-term users.

Warming up is often required at the beginning of exercise, which is suitable for small strides. After warming up, larger strides are required to meet the exercise needs. The user's footsteps often need to be adjusted. Therefore, the past stepping fitness equipment has the disadvantages of limited footstep range and inability to adjust. And such a stride limit does not necessarily meet the needs of all users. For example, users of different genders or ages have different demands on the stride length, just like the amount of exercise required by the elderly and children is different from that of young men. It is the same reason that the amount of exercise required must be different. Avoid strong use of unsuitable and non-adjustable fitness equipment, which is also prone to danger when used.

China Taiwan Patent No. M391978 discloses an adjustable lever to change the inclination angle of the support to the frame, and adjust the inclination of the linear movement track of the pedal according to user needs, which can provide a simulation of climbing a steeper ladder or a smaller slope. ladder. However, this adjustment is limited to the adjustment of the inclination of the linear movement of the board, and cannot provide the user with the ability to adjust the stride size of the linear movement. The user must be limited to the range of the pedals of the exercise equipment to exercise, which may cause injuries that may cause overstretched muscles in the early stages of exercise. Due to the need to stand all the way in the use state, when the user's foot strength is overwhelmed, it may be necessary to suspend the large stride stepping action at any time during the stepping action, or change the foot to step on the force to avoid falling. Presently known stepper exercise equipment does not all provide this design.

The pivoting position of the rotating connecting rod can be adjusted to adjust the action angle of the crank and the rotating angle of the pedal tube. In other words, You can adjust the user's pedaling range. A variety of adjustable stepping steps can further provide users with a complete exercise cycle, such as: a complete training process from warm-up stride requirements to intense exercise stride requirements. The step length can be adjusted so that the user's height and leg length are not limited, and it can also meet the needs of multiple users, such as the use of the whole family and public places.

Since the user is standing during the whole process of use, the safety during use is very important. The pulley and the left and right cranks are assembled and combined by a one-way bearing, so that the crank and the pulley can be separated and rotated independently at different speeds. That is, when the user's footsteps have not stepped on the predetermined position, they suddenly stop or change directions, so as to ensure that the user's footsteps will not be affected and cause the danger of an imbalanced center of gravity.
