Description

elliptical machine

technical field

The utility model relates to an elliptical machine, in particular to an elliptical machine, which is provided with a rotating wheel on the bottom frame and an interlocking hand handle and pedals on the wheel, so that the user can perform exercises on it through the interlocking relationship. Equipment for circular exercise like climbing a ladder.

Background technique

The elliptical machine is a kind of indoor sports equipment designed based on imitating walking movements. It is different from other common fitness equipment in that it is mostly provided with a rotating wheel on a base frame, and the rotating wheel is connected to a flywheel. A damping device is arranged on the flywheel, and a hand handle that can swing back and forth is pivoted from both sides of the bottom frame, and the hand handle is bent and extended from the bottom end and is provided with a corresponding human foot at the extension end. A pedal, and the handle bar, the pedal and the rotating wheel are pivotally connected to each other through a plurality of linkage rods, so that the user can step on the pedal forward on the elliptical machine through two casters on the one hand, and the other On the one hand, cooperate with both hands to hold the handle to push and pull back and forth, and then drive the pedals to circulate in an elliptical track to achieve a circular and coordinated walking movement effect;

However, there are many mechanism principles of elliptical machines currently on the market, but generally only one rotating wheel is used as the main mechanism to drive the circulation. However, while driving the circulation, the rotating wheel is also the main support point for supporting the weight of the human body and applying force, so The design of using a single rotating wheel as a support without other force points to distribute the force evenly to the handle bar and pedals will easily cause the user to use the arm to exert a large amount of force to provide the hand movement at certain angles during the exercise process. The handlebars drive the cycle, and at certain angles, you must use your feet to step on the pedals with greater force. Such an uneven force application method will easily cause the elliptical machine to rotate unsmoothly, and more importantly, lose weight. The coordination training effect of the elliptical machine has an adverse effect on the user's exercise.
