Abstract

Bicycle pedal and gear mechanism with pedal cast in one piece with axisoffset from the platform, articulated on one or more bearings fixed to thecrank base. Will be constructed of steel, aluminium, Duralumin, Titanium, oran alloy of these metals, and of composite materials, carbon fibre, fibreglass or a mixture of the latter.<IMAGE>

   Description : Pédalier de vélo a pédale monobloc à axe décalé de la plate-forme de pédalage, articulé sur un ou des roulements fixés a l'interieur de la base des manivelles. 



  L'invention concerne la partie inférieure de la manivelle et la pédale de type monobloc qui est   inséree   dans une cuvette ménagée dans la base et calée dans un ou des roulements par un système de vis et de   serre-clips ; l'axe etant décale   de vingt millimètres vers le bas de la   pédale amenagée   en plate-forme recevant le pied de l'utilisateur. 



  Le déport de la pedale fera que la plate-forme decrira une ellipse vingt millimètres plus basse, raccourcissant le temps de passage du point mort haut, permettant a l'utilisateur, et c'est le but de l'invention, d'utiliser des manivelles plus longues que celles qu'il utilise habituellement, lui donnant plus de forces dans le secteur favorable après le point mort haut. 



  Ce type de manivelle sera construit en Acier, Aluminium, Durai, Titane ou alliage de ces métaux, en matériau composite, Fibre de Carbonne, Fibre de verre ou mélange de ces matériaux. 



  La longueur de ces manivelles s'échelonnera de   120   mm a   230   mm ou plus suivant le gré de l'utilisateur.

   Description: Bicycle pedalboard with monobloc pedal with axis offset from the pedaling platform, articulated on one or more bearings fixed inside the base of the cranks.



  The invention relates to the lower part of the crank and the monobloc type pedal which is inserted into a bowl provided in the base and wedged in one or more bearings by a system of screws and clip-on clips; the axis being shifted by twenty millimeters downwards from the pedal arranged in a platform receiving the foot of the user.



  The offset of the pedal will cause the platform to describe an ellipse twenty millimeters lower, shortening the time of passage from top dead center, allowing the user, and this is the aim of the invention, to use cranks longer than those he usually uses, giving him more strength in the favorable sector after top dead center.



  This type of crank will be built in Steel, Aluminum, Durai, Titanium or an alloy of these metals, in composite material, Carbon fiber, Fiberglass or a mixture of these materials.



  The length of these cranks will range from 120 mm to 230 mm or more depending on the user's preference.

Claims (1)

Revendications : EMI2.1 Je revendique le fait que le déca ! age de la pedale monobloc à axe décalé permet un franchissement plus aise du point mort haut, la plate-forme de pédalage se trouvant vingt millimètres plus bas dans cette position ; elle parcourt une ellipse plus courte et rejoint plus \ite le secteur force de la poussée du pied de l'utilisateur ; de plus la possibilite d'utiliser des manivelles plus longues (suivant le principe du bras de levier) sera- à coup sur vecteur de vitesse plus élevée. Claims:  EMI2.1  I claim the fact that deca! age of the one-piece pedal with offset axis allows easier crossing of top dead center, the pedaling platform being twenty millimeters lower in this position; it traverses a shorter ellipse and joins more \ ite the sector force of the push of the foot of the user; more the possibility of using longer cranks (according to the principle of the lever arm) will be suddenly on higher speed vector.
