Description

  

  Manivelle de pédale pour     bicyclette.       La présente invention se rapporte à une  manivelle de pédale, pour bicyclette. Cette  manivelle est caractérisée en ce qu'elle est  divisée en deux branches qui vont en s'écar  tant vers l'extérieur, réciproquement, par  rapport à l'axe auquel elles sont connectées  par des raccords et une douille de fixation.  



  Le dessin annexé représente, à titre  d'exemple et schématiquement, un mode de  réalisation de l'invention.  



  La manivelle représentée est constituée  par une première partie 1, droite, compor  tant le forage fileté habituel 2 dans lequel  vient se visser la pédale. Cette première  partie se divise au point 3 en deux bran  ches 4 et 5 qui vont en s'écartant récipro  quement pour se raccorder par des parties       amant    un arc 6 et 7, avec la douille ou       l'smanchon    de fixation 8, qui est fixé. de  faon     habituelle    sur l'axe de transmission.  



  L'avantage     @btde    cette manière con  siste     principalement        en    un plus grand mo-    ment d'inertie, et par suite en une meilleure  distribution de la transmission des forces,  plus particulièrement à proximité du point  mort, qui se trouve dépassé avec une grande  facilité.  



  La manivelle de pédale décrite ne pré  sente pas une augmentation de poids par  rapport aux manivelles de pédale connues  jusqu'à présent; elle est établie et se monte  avec la même simplicité que les autres ma  nivelles.



  Pedal crank for bicycle. The present invention relates to a pedal crank for a bicycle. This crank is characterized in that it is divided into two branches which move apart towards the outside, reciprocally, relative to the axis to which they are connected by fittings and a fixing sleeve.



  The accompanying drawing represents, by way of example and schematically, an embodiment of the invention.



  The crank shown is constituted by a first part 1, straight, comprising the usual threaded borehole 2 in which the pedal is screwed. This first part is divided at point 3 into two branches 4 and 5 which go apart reciprocally to be connected by parts making an arc 6 and 7, with the sleeve or the fixing sleeve 8, which is fixed. . in the usual way on the transmission axis.



  The advantage @bt in this way consists mainly in a greater moment of inertia, and consequently in a better distribution of the transmission of the forces, more particularly near the neutral point, which is easily exceeded. .



  The described pedal crank does not present an increase in weight compared to the pedal cranks known hitherto; it is established and assembled with the same simplicity as the other my levels.
