Elliptical machine improvement

This creation is about the improvement of an elliptical machine, especially an elliptical machine that can independently control the resistance when swinging or stepping on or mixing and pedaling.

In the field of fitness machines, the most common one is a kind of pedaling elliptical machine. Because of its simple use, the hands and feet are like running, and the pedaling action of the pedal is shaped like an elliptical trajectory. For the elliptical machine, or stepping on the elliptical fitness machine; in general, the elliptical machine, the control of its magnetic control mostly focuses on the resistance regulation of the swinging of the swinging rod, because it directly links the upper and lower pedaling resistance of the pedaling rod by the connecting rod, so that The construction is extremely complicated, and the volume of the overall elliptical machine is increased, resulting in an increase in transportation costs and a lack of space.

Another deficiency is that the resistance of the hands is different from the resistance of the feet. The movements are the same as the resistance of both hands and feet, so the exercise effect should not be obtained, and it may be due to the movement of the feet. Resistance must accommodate the resistance of the hands, and in only one mode of control, it is impossible to get the proper exercise and fitness.

In order to solve the above-mentioned conventional problems, the first magnetic control wheel set respectively controls the resistance of a first and second swing lever transmissions to the first transmission wheel, and at the same time, the swinging lever swings the pedal to move forward and backward. The pedal lever is pivotally connected to the first and second transmission rods, and the first and second transmission rods are respectively The pivoting is alternately oscillating on the first and second pivots; and the second magnetically controlled wheelset respectively controls the pedaling resistance of the first and second pedaling poles, and the first and second transmission rods are synchronously coupled with the coaxial transmission First and second pulling elements, the first and second pulling elements respectively fix a first and second ropes, so that the first and second ropes are connected to a first and second eccentric shafts to mutually tow and rotate the second magnetron wheel set a second transmission wheel, wherein the second magnetron wheel of the second magnetron wheel set is controlled by the pedaling bar to be stepped up and down; and is further disposed on a crank of one of the eccentric shafts of the second magnetron wheel set a magnetic rotating base, respectively, a first magnetic element is fixed on opposite sides of the magnetic rotating base, and when the magnetic rotating base rotates, at a suitable position where the magnetic element passes, a magnetic body identical to that of the first magnetic element is provided The two magnetic elements are kept in a repulsive state forever, so as to control the first and second eccentric shafts to remain in an overlapping position where the moment is not zero, so that the pedaling pole is kept smooth under the pedaling, and by the improved simple structure, Obtain independent control of the pendulum and the pedal Force, it has a broader range of motion outside, and has a reduced volume, to reduce handling costs money.

When the user steps on the pedaling pole and holds both hands on the upper part of the first and second swinging rods, applying a first and second swinging shaft pivotally connected to the frame, the first and second swinging shafts are also Fixing a first and a second connecting rod respectively, wherein the first and second connecting rods are interlocked with the first transmission wheel of the first magnetron wheel set, so that the first and second swing rods alternately move the first and second swing shafts to reciprocate Torsing to separately adjust the rotation of the first magnetron wheel set, so that the first magnetron wheel set controls the swinging resistance of the first and second swing bars, and the first and second transmissions pivotally connected to the pedaling bar The rods are respectively pivotally connected to the first and second pivoting seats, and the first and second pivoting seats are respectively fixed on the first and second pivoting shafts, and the first and second pivoting shafts are respectively fixed on the coaxial one And two traction elements, the first and second traction elements are respectively connected to the first and second ropes on the rear side, and the first and second ropes are respectively fastened to the front end by the first and second traction elements to be fixed to the first and second On the eccentric shaft, the first and second eccentric shafts are respectively connected to a first and second cranks, The first and second cranks are disposed on a main shaft such that the first and second eccentric shafts are located on two sides of the main shaft of the second transmission wheel, so that the second transmission wheel of the main shaft transmission drives the second magnetic control wheel to adjust the rotation resistance thereof. To provide resistance control for the pedaling up and down.

In order to achieve the above object, the present invention provides an improvement of an elliptical machine, which can independently adjust the swing resistance of the swing rod, so that the first magnetron wheel can only control the resistance of the pedaling movement before and after the pedaling. The second magnetron wheel train can independently regulate and control the pedaling rod for the resistance of the upper and lower pedaling movements, and the above-mentioned pendulum rod and the pedaling rod can be mixed for swinging and pedaling to form an elliptical pedaling action for individual adjustment of the hands and feet. The magnitude of the resistance is to provide an individual control of the degree of exercise and the resistance training effect.

Another object of the present invention is to connect a first magnetic member to the first crankshaft connected to the first eccentric shaft, a magnetic rotating seat, a first magnetic component fixed at both ends thereof, and a first magnetic component fixed to the first magnetic component. Fixing a second magnetic element at a position through which the first and second magnetic elements are of the same polarity, so that the first magnetic element and the second magnetic element are repelled by the same polarity, and the second magnetic element is at the position of the first magnetic element The eccentric shaft can push the first eccentric shaft away from the overlapping position of the zero moment to avoid jamming and cause the smooth rotation phenomenon.
