STEP-BIKE

Abstract: The invention of this Step-Bike moved by Horizontal Pedals with or without Velocities contain a pair of Horizontal Pedals (right and left) on which when one is up (1) the other is down (2) and the alternating propelling force of the right and left Legs of a Person on it, make force on two opposed Shafts (3) which connect by Liners (4) on a Pinion with right and left Crank (5) which through a Transmitting Shaft or Chain (6) connect on a Pinion fixed on a Back Hub (7) that may include, on a velocities option, Internal Gears (from 3 to 10) and Internal Brakes like Shimano Nexus Hub or equivalent - this eliminates the needing of external Gears and Brakes. Complementing this inventive part, the Step-Bike contain a Steel or Aluminium Tubular Frame with Fork, Direction, Handle-bar, Brakes on Fork, Brake Cable and Front Brake Lever, Revo-Shift Lever (in case of Gears), a Front Wheel and a Back Wheel.

Description: DESCRIPTION STEP-BKE The present invention refers to a Step-Bike moved by Horizontal Pedals with or without Velocities. In general any Mini-Scooter is composed of two wheels , a platform to put the foots , a handle-bar to put the hands and a back foot brake. This traditional Mini-Scooter is moved by a Person impulsion , putting one feet on platform and another on floor and have two disadvantages: - on meadle and big distances it is overtired - it is very unbalanced. This invention have the solutions to that limitations. Indeed , the Horizontal Pedals Step-Bike we invented have the following advantages: 1° - a Person can Step kilometres without fatigue 2° - it is not unbalanced 3° - it is similar to the utility of a bicycle. The invention of this Step-Bike moved by Horizontal Pedals with or without Velocities contain a pair of Horizontal Pedals ( right and left ) on which when one is up ( 1 ) the other is down ( 2 ) and the alternating propelling force of the right and left Legs of a Person on it , make force on two opposed Shafts ( 3 ) which connect by Liners ( 4 ) on a Pinion with right and left Crank ( 5 ) which through a Transmitting Shaft or Chain ( 6 ) connect on a Pinion fixed on a Back Hub ( 7 ) that may include, on a velocities option, Internal Gears ( from 3 to 10) and Internal Brakes , like Shimano Nexus Hub or equivalent - this eliminates the needing of external Gears and Brakes. When a Pedal is up ( 1 ) the other is down ( 2 ) and with the back Wheel movement they altemate.Then the continuous Step-Bike movement is made by the alternating propelling force on Pedals of a Person Legs. Like this a Person may Step kilometres without fatigue and stopping. And in case of having Velocities, we can put a low or a high speed for a easily Step. Complementing this inventive part , the Step-Bike contain a Steel or Aluminium Tubular Frame with Fork, Direction, Handle-bar , Brakes on Fork, Brake Cable and Front Brake Lever, Revo-Shift Lever ( in case of Gears ) , a Front Wheel and a Back Wheel. For the construction of this Step-Bike we resolved some Tecnical Problems: A) the Horizontal Pedals setting problem B) the Horizontal Pedals size problem in such a way that maximize the utilization and n irώ-αize the Legs stress C) the Shafts size in such a way that do not make the anti-pedal effect D) the Liners , Pinion , Cranks , Chain or Transmitting Shaft collocation problem E) the back Hub collocation , running well with the Chain or Transmitting Shaft So, a completely different system from the traditional Mini-Scooter. This Step-Bike have completely different materials and we resolved various tecnical problems to make it.

Claims: CLAIMS A Step-Bike moved by Horizontal Pedals with or without Nelocities characterized by the Legs of a Person making propelling force on a pair of Horizontal Pedals ( right and left ) on which when one is up ( 1 ) the other is down ( 2 ) they make force on two opposed Shafts ( 3 ) which connect by Liners ( 4 ) on a Pinion with right and left Crank ( 5 ) which through a Transmitting Shaft or Chain ( 6 ) connect on a Pinion fixed on a Back Hub ( 7 ) that may include, on a velocities option, Internal Gears ( from 3 to 10) and Internal Brakes like Shimano Nexus Hub or equivalent - this eliminates the needing of external Gears and Brakes. A Step-Bike moved by Horizontal Pedals according to Claim I characterized by being complemented with a Steel or Aluminium Tubular Frame with Fork, Direction, Handlebar , Brakes on Fork, Brake Cable and Front Brake Lever, Revo-Shift Lever ( in case of Gears ), a Front Wheel and a Back Wheel .
