Stationary exercise machine

Abstract

Disclosed is an exercise machine of the type which have pedals or foot plates through which a person can, in use, transfer kinetic energy to the machine, which machine comprises a feature for vibrating the pedals or foot plates during exercise.

1 . An exercise machine which has pedals or foot plates through which a person, in use, transfers kinetic energy to the exercise machine, wherein the exercise machine comprises a means for directly vibrating the pedals or foot plates during exercise in the form of a rotatable pedal or footplate mounting shaft of which a rotation axis and a pedal or footplate mounting point is offset to cause a wobble, vibration or oscillation of the pedals or foot plates during exercise. 
     
     
         2 . The exercise machine as claimed in  claim 1 , which is selected from the group consisting of a bicycle, a stationary exercise bicycle and an elliptical exercise machine. 
     
     
         3 . (canceled) 
     
     
         4 . The exercise machine as claimed in  claim 1 , wherein the exercise machine is a bicycle, the bicycle comprising:
 at least one stationary gear mounted on each side of the bicycle and with a circumference similar to a circumference of a virtual circle created by rotating pedal shafts of the bicycle as the rotating pedal shafts complete one revolution around the at least one stationary gear;   at least one crank arm rotatably mounted and connected at one end of the at least one crank arm through a bottom bracket of the bicycle; and   a shaft rotatably mounted through a hole defined in a free end of the at least one crank arm with one end of the rotatably mounted shaft extending inwards towards the bicycle and provided with a coaxial gear respectively engaging the at least one stationary gear, with another end of the rotatably mounted shaft extending outwards provided with a socket for receiving a rotating pedal shaft of a bicycle pedal of the pedals or foot plates, wherein the socket is offset from an axis of the rotatably mounted shaft.   
     
     
         5 . The exercise machine as claimed in  claim 4 , wherein a gear ratio of the at least one stationary gear and the coaxial gear is selected such that at a pedaling cadence range of 70 to 100 revolutions per minute (rpm) the rotating pedal shaft of the bicycle pedal will cycle at 30 to 35 Hertz. 
     
     
         6 . The exercise machine as claimed in  claim 5 , wherein the offset and an amplitude of the wobble, vibration or oscillation is between 3 and 5 mm. 
     
     
         7 . The exercise machine as claimed in  claim 4 , wherein the bicycle is a stationary exercise bicycle.
