An exercise equipment comprises a display and a rotating mechanism, which includes a rotatable body and a stationary body. The rotatable body connects with the display, and the stationary body connects with a mechanism of the exercise equipment. The display rotates with the rotatable body, whose angle of rotation has an upper limit to avoid damage to wires. In addition, the rotating mechanism can emit a sound to notify the user that the display has been rotated to a specific angle.

An embodiment of the present invention provides an elliptical trainer including structures featuring a first amplitude, a second amplitude, and a third amplitude. By the driving of cranks and the combination of the three amplitudes, the elliptical trainer's pedals move along a closed ellipse path. In addition, the first amplitude is more than twice or three times of the third amplitude, resulting in a wide adjustment range of the stride of the pedal. Accordingly, the elliptical trainer is applicable to users of various heights.

An embodiment of this invention discloses a folding mechanism of a rowing machine that comprises a first frame, a second frame, a saddle member, and a control member. A front of the second frame includes a guiding portion that comprises an operation cut and a storage cut. The saddle member fixes with a rear end of the first fame and straddles on the rear end of the first frame. The saddle member includes a slot, and the first frame pivotally connects with the second frame via a pivot of the saddle member. The control member is arranged below the first frame and includes a bar at its rear end. The rowing machine can be folded for storage or spread for operation by switching the bar into the storage cut or operation cut.

An exercise device includes a frame, two first swing arms, two second swing arms, two pedals, a resistance device, two cranks, two link rods, two supporting mechanisms, two rock rods, and two adjusting devices. Each first swing arm couples with the frame and has a lower end coupling with a first end of one second swing arm. Each second swing arm has a second end coupling with one pedal. Each crank has a first end coupling with the resistance device and a second end coupling with a first end of one link rod. Each link rod has a second end coupling with one second swing arm. Each rock rod has a first end pivotally coupling with a fulcrum of one supporting mechanism and a second end coupling with one second swing arm. Each adjusting device adjusts the distance between the second end of one rock rod and one fulcrum.

An exercise device comprises a frame, two first swing arms, two second swing arms, two pedals, a resistance device, two cranks, two link rods, a lever bracket, two rock rods, and an adjusting device. Each first swing arm has a first end coupling with the frame and a second end coupling with a first end of one second swing arm, which has a second end coupling with one pedal. Each crank has a first end coupling with the resistance device and a second end coupling with a first end of one link rod, which has a second end coupling with one second swing arm. The lever bracket pivotally couples with the frame and has two fulcrums. Each rock rod has a first end coupling with one fulcrum and a second end coupling with one second swing arm. The adjusting device adjusts the distance between the fulcrums and an axle.

A figure trimmer comprises a chassis, a pedal set, a rotating assembly, at least a first elastic component, and at least a second elastic component. The pedal set is arranged on the chassis and is able to restrictedly rotate in horizontal and vertical direction. The rotating assembly couples to the pedal set and the chassis, so as to drive the pedal set rotating in the horizontal direction. When the pedal set rotates in the horizontal direction, the first elastic component exerts an opposite reaction force to the pedal set. When the pedal set rotates in the vertical direction, the second elastic component exerts an opposite reaction force to the pedal set.

An elliptical trainer comprises a reciprocal-movement mechanism and an angle-adjusting chassis. The angle-adjusting chassis comprises a frame, a guider, an angle-adjusting assembly, and an intermediary part. Both the front end of the frame and the rear end of the guider may contact a supporting surface, and the rear portion of the frame may be pivotally coupled with a front portion of the guider. The angle-adjusting assembly is arranged near the rear portion of the frame, and the intermediary part is arranged at or near or attached to the front portion of the guider. The angle-adjusting assembly pushes the intermediary part, such that the guider rotates around its rear end, and the frame rotates around its front end, resulting in varying a first angle between the guider and the supporting surface and varying a second angle between the frame and the supporting surface.

A foldable treadmill includes a base for running or walking, a frame set pivotally connected with the base, and a folding mechanism for folding the frame set. The folding mechanism has a control assembly and a sliding rod connected with the frame set and capable of being locked or released by the control assembly. When the control assembly locks the sliding rod at a first position, the frame set cannot be rotated, and when the control assembly releases the sliding rod, the frame set can be rotated to a storage position thus pulling the sliding rod to a second position.

A workout device with a foot-oriented elliptical loop is provided and bilaterally equipped with a transmission rod, a first link rod, a driving rod, a second link rod, a swing arm, and a supporting rod. The transmission portions are pivotally coupled to cranks to enable the cranks to undergo revolution. The supporting rods each have a supporting portion to support a user's feet. The aforesaid rods interact with each other. The supporting portions of the supporting rods move along a closed elliptical loop with segmental junctions spaced apart by a relatively short distance, such that the user's treading process is prevented from undergoing abrupt descents, unsmooth transitions, and thus jolts.

The hand-oriented and foot-oriented elliptical mechanisms enable a user's hands and feet to revolve in the same direction and follow closed paths, respectively. Hence, the user can exercise ergonomically and work different muscle groups.
