Abstract: An elliptical machine includes: a transmission mechanism disposed a the base, one end of the lateral swing track disposed on both sides is pivoted at the base, and each lateral swing track can swing laterally; a connecting rod and a stepping mechanism are disposed on both sides of the transmission mechanism, and the front end of the front connecting rod in each mechanism is pivotally connected to the base; a front end is connected to the rear connecting rod of the front connecting rod in a universal joint type, the rear connecting rod is disposed on the corresponding track; the rear connecting rod free end part is pivoted to the pedal. When the pedal is stepped on, the front connecting rod is reciprocally extended with the transmission mechanism, and the user can freely manipulate the swing angle of the lateral swing track through the lateral force applied to the pedal.

Abstract: An elliptical machine has a base, an upright column fixed to the base, a transmission mechanism mounted on the base, and two link mechanisms respectively connected with opposing sides of the transmission mechanism. Each link mechanism includes a first link rod that is telescopic and connected with both the transmission mechanism and the base, and a second link rod having a pedal and connected with the first link rod such that the pedals of the two link mechanisms are respectively linked to the transmission mechanism through the first and second link rods. When a user uses each pedal, a total length of the corresponding first link rod is reciprocatingly and continuously changed, so that a top end of the first link rod makes a first circulatory movement along a first elliptical path, and the corresponding pedal synchronously makes a second circulatory movement along a second elliptical path.

Abstract: An elliptical machine includes a base and an upright column fixed to the base; a transmission mechanism mounted on the base, the bases on both sides of which are respectively provided with the link mechanism connected with the transmission mechanism wherein each link mechanism includes a first link rod connected with the transmission mechanism, and a second link rod having a pedal and connected with the first link rod. The first link rod is telescopic and connected to the base. When the user uses the pedal of two link mechanisms to link the transmission mechanism through the link rods, the total length of the first link rod is reciprocatingly and continuously changed, so that the top end of the first link rod can make the circulatory movement along an elliptical path, and interlocks the second link rod, and the pedal synchronously can make the circulatory movement along an elliptical path.

Abstract: An elliptical trainer has a base, and two crank assemblies, a handle assembly and a linkage assembly mounted on the base. Each crank assembly has two cranks and a transmission wheel. A transmission strip is mounted around the transmission wheels of the crank assemblies to simulate rotations of the crank assemblies. The linkage assembly connects the cranks of the crank assemblies to the handle assembly. When the elliptical trainer is operated, the linkage assembly drives the cranks to alternately rotate upwardly and downwardly. The cranks that rotate downwardly drag the other cranks to rotate upwardly. Therefore, the crank assemblies and the linkage assembly operate smoothly, and consequently, the user is capable of smoothly performing walking or running movements.
