Description

  

  Mécanisme de direction de cycle.    La présente invention a pour objet un mé  eanisme de direction de cycle qui est caracté  risé en ce qu'un tube de direction de la  fourche du cycle tourne dans     un    tube de di  rection du cadre, par l'intermédiaire d'organes  présentant des surfaces d'appui et de friction  complémentaires de forme sphérique, lesdits  organes étant solidaires respectivement du  tube de direction de la fourche et du tube de  direction du cadre à chacune des extrémités  de ce dernier     tube.     



  La figure du dessin annexé montre, à titre  d'exemple non     limitatif,        une    forme d'exécu  tion de l'objet de l'invention.  



  La figure représente, en partie     ime    coupe,  en partie une vue de l'intérieur.  



  Le tube de direction du cadre comporte,  à sa partie supérieure, une cuvette d'appui  file cc dont il est solidaire et dont la creusure  est établie avec une forme sphérique corres  pondant à la surface d'appui mâle de la pièce  b, laquelle est vissée sur le tube de fourche  et dont le serrage est par conséquent réglable.  



  A la partie inférieure du tube de direc  tion, avec une disposition symétrique, est mon  tée la cuvette d'appui c également solidaire       dudit    tube de direction en présentant une  creusure établie avec une forme sphérique cor  respondant à la surface d'appui mâle de la  pièce d solidaire du tube de direction de la  fourche.  



  Il faut considérer qu'avec ces dispositions  d'appui supérieur et inférieur opposés et    symétriques, on a -un positionnement automa  tique des surfaces portantes (surfaces d'ap  pui sphériques en égard des portées sphéri  ques des cuvettes fixes).  



  De plus, ces surfaces portantes sphériques  réduisent la pression, ce qui évite tout grip  page, échauffement ou matage.  



  Il apparaît que cette disposition, en sup  primant les billes, permet une grande écono  mie tout en facilitant le montage et le réglage  en position. des organes qui s'effectue automa  tiquement, cela     sans    nuire à une rotation  douce de l'ensemble     tournant.     



  Il reste entendu que la disposition ci-dessus  peut être inversée en ce qui concerne la dispo  sition des cuvettes en égard des surfaces d'ap  pui mâles.



  Cycle steering mechanism. The present invention relates to a cycle steering mechanism which is characterized in that a steering tube of the cycle fork rotates in a steering tube of the frame, by means of members having surfaces. complementary bearing and friction spherical shape, said members being secured respectively to the steering tube of the fork and to the steering tube of the frame at each of the ends of the latter tube.



  The figure of the appended drawing shows, by way of non-limiting example, one embodiment of the object of the invention.



  The figure shows, partly a section, partly an interior view.



  The steering tube of the frame comprises, at its upper part, a support cup file cc which it is integral with and whose hollow is established with a spherical shape corresponding to the male support surface of part b, which is screwed onto the fork tube and the tightening of which is therefore adjustable.



  At the lower part of the steering tube, with a symmetrical arrangement, is mounted the bearing cup c also integral with said steering tube by having a recess established with a spherical shape corresponding to the male bearing surface of the part d integral with the steering tube of the fork.



  It should be considered that with these opposing and symmetrical upper and lower support arrangements, there is an automatic positioning of the bearing surfaces (spherical support surfaces with respect to the spherical bearing surfaces of the fixed cups).



  In addition, these spherical bearing surfaces reduce pressure, which prevents any grip page, heating or matting.



  It appears that this arrangement, by removing the balls, allows great savings while facilitating mounting and adjustment in position. organs which is carried out automatically, without harming a smooth rotation of the rotating assembly.



  It remains understood that the above arrangement can be reversed as regards the arrangement of the bowls with regard to the male support surfaces.
