That is, the limbs cooperation exerciser controls the rotation of the first operating member or the second operating member to lower the difference between the rotating speeds of the first operating member and the second operating member.

A linear powered input device that utilizes linear input from a user and converts the linear input rotational energy to perform work. The linear input is generated by lever arms having a slotted attachment at a pivot point that allows a free end of the lever arms to move linearly rather than in an arcuate path. The lever arms are connected to a power transmission mechanism that wraps around one or more drive wheels having one-way bearings mounted on one or more output shafts. The output shafts can be connected to any type of auxiliary device to perform the desired work. Output wheels may be mounted on the output shafts and operatively connected by a transmission link that allows linear motion of any lever arm in any allowable direction to cause the output shaft to rotate in the same rotational direction so as to receive continuous input.

An exercise device of the type including a frame with a first crank assembly rotatably coupled to the frame about a first axis and a second crank assembly rotatably coupled to the frame about a second axis. A control system may be used in communication with the first crank assembly and the second crank assembly, which may provide a synchronous movement of the first crank assembly relative to the second crank assembly. A pedal arm may be provided with a first end pivotally coupled to the first crank assembly and a pedal positioned on a second end. A crank link may be used with one end coupled to the second crank assembly and a second end coupled to the pedal arm. The crank link may be movable on the pedal arm which may provide varying paths of motion of the pedals.

A transmission structure of a climbing machine for an operator to operate in a standing position is disclosed. The transmission structure of the climbing machine includes a base, a support frame, a first slide rail, a second slide rail, a first transmission unit, a second transmission unit, a first handle slider, a first pedal slider, a second handle slider, a second pedal slider, and a resistance unit. The climbing machine is used to train the synchronized and coordinated movements of hands and feet for simulating rock climbing and mountaineering. The support frame, the first slide rail, the second slide rail, the first transmission unit and the second transmission unit are all located at the center line position of the upright trunk of the operator. The volume of the climbing machine can be reduced greatly to save the space occupied.

A foldable gymnastic machine comprising a supporting structure to rest said gymnastic machine on a resting surface, comprising a front portion, comprising in turn a resistance member, and a rear portion, an exercise device, through which a user performs a gymnastic exercise, coupled to said supporting structure and to said resistance member, capable of resisting during the execution of a gymnastic exercise, said exercise device comprising a second pair of levers for the feet, in turn comprising a first and a second lever, each provided with a first end, coupled to said supporting structure, and a free second end, capable of fitting said user's feet during the execution of the gymnastic exercise, said gymnastic machine being characterized in that said first and second lever of said second pair of levers for the feet are capable of passing from an open position, in which the user can perform the gymnastic exercise, to a closed position, when the gymnastic machine is not in use.

An exercise machine is for performing a striding exercise motion. The exercise machine has a frame, first and second pedal members, first and second foot pads on the first and second pedal members, respectively, wherein the first and second foot pads are configured to move in respective elliptical paths during the striding exercise motion, and first and second rocker arms. The first and second pedal members are pivotably coupled to the first and second rocker arms and move with the first and second rocker arms relative to the frame. An adjustment device pivotably couples the first and second rocker arms to the frame. The adjustment device is configured to actively adjust and set a position of the first and second rocker arms relative to the frame, respectively, which thereby changes an incline shape of the elliptical paths, respectively, during the striding exercise motion.

An exercise device with controllable training modes includes a base, a first exercise mechanism, a second exercise mechanism, and an operating mechanism. The first exercise mechanism has a first gear member. The second exercise mechanism has a second gear member. The operating mechanism has a third gear member. When the third gear member is at a first position, the third gear member meshes with the first gear member and the second gear member to form a linked state, so that the first exercise mechanism and the second exercise mechanism are operatively linked and coupled and swing in opposite directions. When the third gear member is at a second position, the third gear member is disengaged from either the first gear member or the second gear member or both to form a free state, so that the first exercise mechanism and the second exercise mechanism individually swing.

A climbing exercise machine includes a beam supported on two columns supported on a base. Two handles are movably supported on the columns, respectively. The handles are movable in opposite directions. Two treads are movably supported on the columns, respectively. The treads are movable in opposite directions. An input axle is supported on the columns. The input axle is rotated as the handles and the treads are moved. A transmission case connects the input axle to an output axle. A disc is connected to the output axle. A frame is connected to the beam. A resistance element is supported on the frame. The resistance element includes a magnet. The resistance element is movable relative to the disc to adjust magnetism exerted on the disc by the magnets.

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.

A vertically oriented fitness apparatus utilizes a combination of upper and lower assemblies resistant to vertical motion when the user pushes and pulls against crossbar members of the assemblies vertically. In alternate embodiments of the apparatus, resistance is provided by a dual action dashpot such as an adjustable bidirectional hydraulic damping cylinder which may be used in combination with spring resistance elements. The user is thus able to perform strength training and fitness conditioning exercises for both upper and lower extremities, and their core simultaneously while using the apparatus.
