Definitions

• the present invention relates to an apparatus for physical exercise, and a crank device and foot supporting platforms for use with such apparatus, as defined in the introductory part of the attached independent claims.
• the invention is useful to provide for a choice among a plurality of different workout options related to simulation of movements, and to provide means for adjustment thereof according to user defined options.
• a single apparatus capable of providing to highly satisfactory degree exercise assistance to such large variety of simulated movements is yet to be found on the market.
• the present invention thus intends to solve inherent shortcomings of currently available exercise apparatus, and the present invention therefore intends to provide various embodiments of a single multifunctional piece of equipment or exercise apparatus which may be utilised to assist simulation of different exercises, including walking, jogging, running, skiing and climbing without imparting shock to the user's body joints in the manner of exercise treadmills.
• the inventive apparatus replaces treadmills, all types of steppers, elliptic operation type of apparatus, cross trainers, skiing exercise apparatus and various types of indoors training bikes.
• Another aspect of the invention is strengthening of the joints and more specifically the muscles and tendons.
• Training during instability also called proprioseptive training, has shown positive effects strengthening the muscles round joints.
• a medical study using unstable pedals during training proves significant results. Such pedals are shown in publication WO00/68067 assigned Flexiped AS. The medical test mentioned was published in Scandinavian Journal of Medicine and Science in Sports, Vol. 13, issue 4, August 2003, author: Dr. Per H ⁇ iness.
• the present invention offers inclusion of elements of instability, specifically regarding supporting means for the feet.
• the feet supports will optionally be able to tilt transversely of the path of motion, and in addition have the ability to tilt parallel to the path of motion, to give a toe-heel movement.
• an exercise apparatus with assisting handles for arm movement and for assisting in simulating a range of stepping motions, including walking, jogging, running, climbing and skiing, and with means for manually or automatically adjusting motions from a linear to elliptical path or elliptical like path to the footrest for user's feet.
• Another object of the present invention is to provide the above exercising apparatus with means for producing any desired path or movement wanted by the user, and more specifically provide for selective adjustment to match e.g. stride of the user, size of orbit and the type of exercise chosen, preferably with automatically means.
• Yet another object of the present invention is to provide a controlled posture and angle of the feet supports related to the exercise apparatus to match the stride and any movement required by the user.
• Yet a further object of the present invention is to provide tilting of feet supports being operative on the exercise apparatus to create a degree of instability, which imposes challenges to the muscles and balance of the user.
• Still another object of the present invention is to provide an exercise apparatus, which requires minimal space to operate and store, yet is still easy to operate, simple and reliable in operation and maintenance, and provides a cost-efficient piece of exercise apparatus capable of providing a greater variety of modes of use in a single piece of equipment compared with prior art devices.
• the present invention also aims at providing a crank device useful for the exercise apparatus and which provides for a greater range of modes of use, and is capable of contributing to the versatility previous unknown to a single piece of apparatus for physical exercise.
• the invention utilises cardanic motion for producing a plurality of motions in a training or exercise apparatus.
• the motions are provided by a crank mechanism utilising cardanic motion which on each side of an axle has a disc, sprocket, cog or gear, here referred to as a sun gear, which is fixed relative to a second gear of half the size which revolves around the sun gear.
• the second gear is rotationally fixed on a crank arm, with an axle rotationally running through the sun gear.
• the rotational motion of the second gear is produced through a linkage to the sun gear, the linkage being gears, belts, chains or other mechanical transmission means.
• To the second gear is fixed a second crank arm, which has foot-supporting means.
• the foot supports in a preferred embodiment have means for controlling stability and angle relative to the motion.
• the training apparatus has mechanical means for adjusting a length of the crank arms, e.g. through use of motors and gears.
• the length of the crank arm decides the size and shape of the orbit and is preferably automatically adjustable dependent on speed or desired stride length.
• the orientation of the inventive crank system may be adjustable rotated in order to change the inclination of the path and motion, the rotation of the system preferably assisted by a motor.
• the foot supporting means have also means for adjusting the angle to create a toe-heel tilt.
• the foot supporting means in form of platforms have optional tilt movement with an adjustable mechanism, the movement transverse the stepping motion, for utilising proprioceptive training and exercise.
• a flywheel is mounted on a portion of the frame connected so to rotate as result of the crank movements.
• the flywheel serves as a momentum-storing device to simulate the momentum of the body during various stepping motions. Resistance may be applied to the rotation of the flywheel, to make the motion harder or easier to achieve. This resistance may be co-ordinated with the workout level desired by the user. Similar kind of system is found on training/exercise apparatus, such as ergo-meter bikes, spinning bikes, cross trainers and the like.
• the exercise apparatus would in a preferred embodiment include handlebars, which move as part of a training exercise.
• the handle bars would be pivotally fixed to a forward part of the training apparatus and hinged to bars linked to rotational parts of the crank mechanism in such a way that the bars move in an opposite direction relative to the feet supports giving a full cardiovascular workout.
• the exercise apparatus includes a user input, monitoring and control device, hereinafter referred to as a man machine interface device (MMI) which allows the user to adjust the machine so to achieve desired motion, speed, resistance and path, it being walking, jogging, running, climbing or skiing.
• MMI man machine interface device
• the MMI device is preferably of a touchscreen type but could also be a combination of a display/screen and a panel of buttons.

• Fig. 63 shows the training apparatus shown in fig. 32, with the addition of an electric motor 620 operatively connected to the flywheel 621.
• the motor is either connected to the flywheel directly by gear 622 as indicated on fig. 64a or by pulley and belt 624 shown on fig. 64b.
• an electric DC motor it is possible to change the current so that the motor either can drive the crank arms or provide a resistance to movement of the crank arms when forcibly moved by a user. To have this double function the flywheel is needed for keeping a momentum when the motor is not driving the crank.
• Fig. 65 shows a block schematic of how such a system would be.
• a user is able to select between a forced drive mode 625 or a movement resistance mode 626.
• the CPU 613 activates delivery of power 612 to the motor 620 which will drive the crank device if forced drive mode 625 is selected. If movement resistance mode 626 is selected the current setting of the power in the motor will cause the drive direction of the crank device to be in reverse direction so as to give a movement resistance when crank is turned.
• foot supporting means or foot supports should be understood as applying to all kinds of pedals, pedal like devices, platforms and other devices for apparatus made for placing feet and stepping on or otherwise moving the feet for turning a crank like device.
