A drive mechanism for an elliptically-driven device includes a drive arm with a foot platform pivot assembly; a crank arm; a foot platform assembly pivotally coupled to the drive arm via the foot platform pivot assembly; a foot platform angle adjustment mechanism operably coupling the foot platform assembly to the crank arm so as to impart a foot platform angle of the foot platform assembly relative to the drive arm that varies during a stroke of the foot platform assembly.

A stationary exercise device having variable footpaths is disclosed. The exercise device includes a frame, a pair of supporting members that have a first end to rotate about an axis and a second end to move along a reciprocating path, a pair of pedals joined to the supporting members, and a guider assembly for adjusting an incline angle of the reciprocating path.

An exercise equipment with an improved connecting bar connecting an exercise foot retaining device to a resistance, wherein a first longitudinal pedal bar is connected to a first bent longitudinal pedal connector bar and a second longitudinal pedal bar is connected to a second bent longitudinal pedal connector bar, the first and second bent longitudinal pedal connector bars each having a bent angle greater than zero and less than ninety degrees to thereby prevent an occurrence of a dead angle.

A stationary exercise device having variable footpaths is disclosed. The exercise device includes a frame, a pair of supporting members that have a first end to rotate about an axis and a second end to move along a reciprocating path, a pair of pedals joined to the supporting members, and a guider assembly for adjusting an incline angle of the reciprocating path.

The invention (variants) relates to a field of sports and medicine, and it concerns training devices, namely, rotary training machines which are used for a simultaneous training of human should, pelvic girdles, and trunk muscles. The claimed invention is based on a task to create a rotary multi-function training machine for the simultaneous training of human shoulder girdle, pelvic girdle, and trunk muscles, while involving all groups of muscles in a balanced manner in order to provide a high quality and efficiency of the trainings at different usage modes of the training machine due to maintaining a synchronization of a rotation of shafts of load modules of the training machine by adjusting a relationship between their rotational speed and efforts applied thereto.

This invention discloses an elliptical exercise apparatus that is characterized in having left and right tracks disposed in a guider frame which is pivotally coupled to a rear portion of the elliptical exercise apparatus. When a user uses the elliptical exercise apparatus, the guider frame is at a use position. When the user folds the elliptical exercise apparatus, the guider frame is at a storage position. A user can complete folding procedure merely by operating the guider frame without lifting some heavy components of the elliptical exercise apparatus.

An exercise machine includes a frame, a first rotary mechanism supported on the frame, a second rotary mechanism rotatably engaging with the first rotary mechanism, and a driving mechanism operatively coupled to the second rotary mechanism and configured to impart rotation of the second rotary mechanism while the driving mechanism is being actuated. The second rotary mechanism is hubless. The second rotary mechanism is configured to absorb and retain an amount of the actuation of the driving mechanism as a moment of inertia while the second rotary mechanism rotates.

An exercise apparatus includes a base frame, a swing unit including a pair of swing arms pivotally mounted at the base frame, a pedal unit pivotally mounted at the swing unit, a travel path constraining unit including a pivot axle pivotally connected to the base frame, a pair of upper crank arms respectively affixed to two opposite ends of the pivot axle in reverse directions and a pair of links respectively pivotally connected between the upper crank arms and the swing arms for limiting the swinging range of the swing unit, a first damping unit for providing a damping resistance to the pedal unit, and a second damping unit for providing a damping resistance to the swing arms.

Apparatus for disabled persons, comprising a skid which optionally may be equipped with wheels, to which skid is connected a device for tightening the user's knees.

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.
