Definitions

  • the invention is a construction for propelling vehicles through the muscular power of the legs and is based on the common bicycle pedal construction with the addition that the pedal axle is mechanically connected to the frame in such as way that the cyclist can apply a torsion force on the pedal with the pedal axle as a rotation line which results in a propelling force for the vehicle.
  • the result is a construction that allows the cyclist to develop a substantially higher power output to propel the vehicle.
  • This invention named "Torque Pedal” is related to propelling vehicles of all sorts by the muscular power of the legs. Special attention will be given to the bicycle as this is the most common application of a vehicle propelled by leg power.
  • This invention offers an improved propulsion system that allows the cyclist to develop substantially more power for the propulsion of a bicycle that the conventional pedal system, as well as offering more comfort in the process.
  • the conventional construction has a dead zone in the highest and lowest position of the pedals in which the cyclist can only produce limited power.
  • a torsion force applied to the pedal surface with the pedal axle as rotation line is not used for propelling the vehicle, because the pedal can rotate freely in its bearings.
  • the foot however is very well capable of generating a torsion force around the pedal axle. This torsion force could very well be used to propel the vehicle, however, conventional constructions leave it unused.
  • the essence of the Torque Pedal is that is allows the cyclist to exploit a torsion force around the pedal axle for the propulsion of the vehicle, next to the traditional pushing force on the pedal axle itself. At the same time, the cyclist is able to generate more power in the so called “dead zone”. In addition the Torque Pedal prevents the cyclist from having to strain the calf muscle without it adding to useful power to the vehicle.
  • the essence of the construction is that the pedal surface is mechanically connected to the frame in such a way that a torsion force applied to the pedal surface with the pedal axle as a rotation line results in a torsion force on the main axle and so results in a driving force for the vehicle.
  • the Torque Pedal can make use of a click binding and a shoe with a ridged sole so that the foot becomes an integral unit with the pedal surface, as is common in bicycle racing.
  • the pedal axle will be situated at the fore foot, identical with conventional pedal shoe bicycle click bindings.
  • the pedal at the highest point will start under an angle of around 45degrees to the horizontal, with the heel up and the toe down.
  • the cyclist now pushes on the heel and pulls up the toes, so creating a torsion force on the pedal surface with the pedal axle as rotation line.
  • Through the mechanical connection between the pedal surface and the frame this results in a torsion force on the main axle.
  • Figure 1 shows a three dimensional impression of the construction.
  • the chain connecting pedal gear and main axle gear is not shown.
  • the pedal construction is not shown. It becomes apparent that the construction of the torque pedal does not alter the charcter of the of the bicycle.

  • Figure 2 shows a cross section at the main axle of the bicycle.
  • a gear is fixed that propels the rear wheel by means of a chain identical to the construction of conventional bicycles.
  • the main axle gear runs on bearings on the main axle and is prevented from rotating by a strip of material that is connected to the frame.
  • Figure 3 shows the second construction option in the form of a cross section at the main axle of a bicycle, including a part of the rear wheel, and shows how the pedal surface is connected through chain gears and chain to the help axle.
  • the help axle runs in bearings in the crank.
  • On the frame side the help axle is connected via a one way clutch to a gear that is meshed in the gear crown.
  • a torsion force on the pedal surface with the pedal axle as rotation line results in a torsion force on the main axle (when the one way clutch blocks) that is exploited for the propulsion of the vehicle.
  • the cyclist places his foot on the pedal surface with his fore foot over the pedal axle as with a conventional pedal construction.
  • the cyclist pushes down on the heel, and if the shoe is clicked into a binding on the pedal he pulls the toe up thus exercising a torsion force around the pedal axle.
  • the torsion force applied by the foot results in a torsion force on the main axle that in turn adds to the propelling power of the vehicle.
  • Figure 4 shows a side view of figure 3 and shows the drive connection between the chain gear fixed to the pedal and the chain gear fixed to the help axle (pedal itself not shown here).
  • the figure shows the ratio of around 1 to 1.7 but could be as much as 1 to 2.2.
  • the figure shows the chain gear fixed on the frame side of the help axle meshed in the gear crown.
  • Figure 5 shows the Torque Pedal construction (option with gear crown) as fixed to a bicycle. It can be seen how the various parts of the construction fit into the bicycle as a whole. The figure shows the construction is feasible without harming the character of the bicycle. The position of the cyclist as well as his leg movements remain unchanged. However in the down stroke the cyclist pushes down on the heel rather than the fore foot.

Abstract

La présente invention concerne une structure mécanique améliorée destinée à augmenter l'efficacité du transfert de la force appliquée à un ensemble manivelle sur la roue arrière d'une bicyclette. Cette structure permet à une force de torsion (couple) exercée autour de l'axe de la pédale d'être transmises sous forme de force d'entraînement à la roue arrière de la bicyclette, en plus de la force de poussée classique exercée contre l'axe de la pédale.
