Description

  

  Bicyclette avec     guidon    moteur.    La     construetion    de bicyclettes dont le       - idon    est monté à pivot à. l'extrémité supé  rieure de la fourche et dont les oscillations  du guidon sont transformées en un mouve  ment rotatif transmis à la roue avant est  connue. Dans une telle bicyclette, l'énergie  des bras et du tronc     du    cycliste agissant al  ternativement sur l'une et l'autre poignée du       guidon    s'ajoute à celle de ses jambes agissant  sur les pédales pour mouvoir la machine.  



       L'objet    de l'invention est une bicyclette  <B>(le</B> ce genre, c'est-à-dire dont le guidon est  monté à pivot à l'extrémité supérieure de la  fourche de façon à pouvoir osciller, ses oscil  lations étant transformées en un mouvement  rotatif transmis à l'aide d'un pignon à roue  libre à. la, roue avant, caractérisé par le fait  que la roue avant, actionnée par les oscilla  tions du guidon, est rendue solidaire du pi  gnon qui la commande aux points morts.  



  Le dessin annexé montre une forme d'exé  cution de l'invention, donnée à titre d'exemple.       Fig.    1 est une vue de face d'une partie  de la machine;       Fig.    2 est une élévation latérale de cette  partie de la machine, et         Fig.    3 une vue d'un détail.  



  Au cadre de la bicyclette est reliée de la  manière usuelle la fourche s portant la roue  avant<I>p</I> et le guidon<I>w.</I> La roue arrière (non  représentée) est actionnée au moyen des pé  dales de la manière ordinaire.  



  La roue avant p joue le rôle de roue mo  trice, grâce à un pignon à roue libre d relié  par une chaîne q avec la roue dentée b.  



  La bielle<I>v</I> relie la manivelle<I>x</I> au gui  don     2v.        Ledit    guidon est pivoté à la tête de  la fourche s, en sorte que tout en actionnant  cette dernière pour la direction, comme dans  une bicyclette ordinaire, il peut osciller dans  un plan perpendiculaire à celui de la roue  avant. Le mouvement oscillant du guidon     w     actionne la. manivelle x et, par     conséquent,     la roue avant p.  



  Deux segments de contact a, diamétrale  ment opposés, sont fixés à la roue dentée     Ü     de telle façon que lorsque la bielle approche  d'un des points morts, un des     segments    a en  tre en contact     avec    l'anneau c qui est mobile  dans un plan parallèle à celui de la roue  avant<I>p.</I> Des ressorts e, fixés au moyeu     f    de  la roue avant maintiennent l'anneau     c    dans      la position concentrique     indiquée    à la.     fig.    3,  position dans laquelle la roue est indépen  dante de son pignon d.

   Dès que la bielle ap  proche d'un point mort de sa course, un des  segments a entre en contact avec     l'anneau    c  et appuie sur celle-ci. L'anneau c sous cette  pression descend et vient     entrainer    à la fois  le pignon à roue libre<I>d</I> et le moyeu<I>f</I> de la  roue avant. Ces deux organes sont, par con  séquent, accouplés l'un à l'autre. Cela a pour  résultat que le pignon à roue libre d est alors  entraîné par le mouvement de la. roue avant p  et, à sa suite, la     chaine        q,    la roue dentée, la  manivelle     ,x    et la, bielle v qui traverse ainsi  le point mort.

   Dès que la bielle v a passé  ce point mort le segment a abandonne l'an  neau c à l'action des ressorts de rappel e, qui  le ramène dans sa position normale (repré  sentée     filc;.    3). La, roue libre est ainsi réta  blie jusqu'au prochain point mort, c'est-à-dire    pendant approximativement un demi-tour de  la roue dentée G. Pour réduire les frottements  provenant du fait que les     mouvements    de  l'anneau mobile c et des segments de contact  a sont opposés, on     peut    utiliser des galets  amortisseurs, en caoutchouc, par exemple.



  Bicycle with motorized handlebars. The construetion of bicycles the - idon of which is pivotally mounted. the upper end of the fork and of which the oscillations of the handlebars are transformed into a rotary movement transmitted to the front wheel is known. In such a bicycle, the energy of the arms and trunk of the cyclist acting alternately on one and the other handlebar grip is added to that of his legs acting on the pedals to move the machine.



       The object of the invention is a bicycle <B> (the </B> this kind, that is to say, the handlebars of which are pivotally mounted at the upper end of the fork so as to be able to oscillate, its oscillations being transformed into a rotary movement transmitted by means of a freewheel pinion to the front wheel, characterized in that the front wheel, actuated by the oscillations of the handlebars, is made integral with the foot gnon who controls it at dead spots.



  The accompanying drawing shows one embodiment of the invention, given by way of example. Fig. 1 is a front view of part of the machine; Fig. 2 is a side elevation of this part of the machine, and FIG. 3 a view of a detail.



  To the frame of the bicycle is connected in the usual manner the fork s carrying the front wheel <I> p </I> and the handlebar <I> w. </I> The rear wheel (not shown) is actuated by means of the pals in the ordinary way.



  The front wheel p acts as a driving wheel, thanks to a freewheel pinion d connected by a chain q with the toothed wheel b.



  The <I> v </I> connecting rod connects the <I> x </I> crank to the gui don 2v. Said handlebars are pivoted at the head of the fork s, so that while operating the latter for steering, as in an ordinary bicycle, it can oscillate in a plane perpendicular to that of the front wheel. The oscillating movement of the handlebars w actuates the. crank x and therefore the front wheel p.



  Two diametrically opposed contact segments a are fixed to the toothed wheel Ü so that when the connecting rod approaches one of the dead points, one of the segments a comes into contact with the ring c which is movable in a plane parallel to that of the front wheel <I> p. </I> Springs e, fixed to the hub f of the front wheel, keep the ring c in the concentric position indicated in. fig. 3, position in which the wheel is independent of its pinion d.

   As soon as the connecting rod approaches a neutral point in its travel, one of the segments a comes into contact with the ring c and presses on the latter. The ring c under this pressure descends and drives both the freewheel pinion <I> d </I> and the hub <I> f </I> of the front wheel. These two organs are, therefore, coupled to each other. As a result, the freewheel gear d is then driven by the movement of the. front wheel p and, following it, the chain q, the toothed wheel, the crank, x and the connecting rod v which thus crosses the neutral point.

   As soon as the connecting rod v has passed this neutral point, the segment a abandons the ring c to the action of the return springs e, which brings it back to its normal position (shown filc ;. 3). The freewheel is thus restored to the next neutral point, that is to say for approximately half a turn of the toothed wheel G. To reduce the friction resulting from the fact that the movements of the movable ring c and contact segments a are opposed, one can use damping rollers, rubber, for example.
