BICYCLE WITH ELLIPSOID DRIVE Russian patent published in 2015 - IPC B62M3/06 A63B23/00 

FIELD: transport.

SUBSTANCE: proposed invention relates to class of vehicles, for instance bicycles, which employ energy of human body muscular contractions as motive force. At the same time, proposed invention also relates to sports equipment and can be used in the area of sport, physical culture and rehabilitation medicine. Proposed bicycle with ellipsoid drive includes frame with handle bar and saddle, wheels and drive with driving sprocket, two reciprocating rods and pedals. The drive consists of ellipsoidal member the inner ellipsoidal surface of which forms working track with indented profile, and pedal mechanism. The pedal mechanism is installed on ellipsoidal member with possibility to move over indented surface of working track and contains operating gear, hold-down gears with screw load regulator, and tightening rollers. Operating gear shaft fixed in pedal mechanism housing with possibility of rotation is made hollow, and driving sprocket shaft passes through the operating gear shaft. Both shafts are connected with stepped clutch one end of which is installed on driving sprocket shaft with possibility of axial movement and forms sline joint with this shaft, the second end of stepped clutch is installed with possibility to form together with outer surface of operating gear shaft the tool joint to transfer torque form sprocket shaft to gear shaft.

EFFECT: combination of vehicle functionality, for instance functions of bicycle and ellipsoidal exercycle, in design of bicycle with ellipsoid drive, as well as in higher efficiency of training action on human body due to increase in amplitude of trained muscles and lower limb joints work.
