Description

  

  Selle.    L'objet de l'invention est une selle de  cycle, motocycle, etc., comportant un cadre  métallique, des anneaux et des organes élas  tiques reliant ces anneaux entre eux et au  cadre, "le tout étant disposé en vue de ré  partir uniformément les     efforts    sur les organes  élastiques et de transmettre uniformément  les réactions de la selle au passager par  toute la surface de cette dernière.  



  Le dessin annexé représente schématique  ment et à titre d'exemple trois formes d'exé  cution de l'objet de l'invention.  



  La     fig.    1 est une vue en perspective d'une  première forme d'exécution ;  La     fig.    2 une vue en perspective d'une  seconde forme d'exécution,  La     fig.    3 une vue en perspective d'une  troisième forme d'exécution,  La     fig.        4;'    une vue de détail relative à  cette dernière forme d'exécution, à plus  grande échelle.  



  A la     fig.    1 le cadre de la selle est cons  tituée par deux pièces métalliques latérales 1  fixées à leur partie postérieure à une pièce  transversale 2. Les pièces 1 et la pièce trans-         versale    2 sont constituées par des fers plats  posés de champ. Ces pièces 1 sont pliées de  manière telle que leurs grandes faces soient  planes. L'extrémité antérieure de ces pièces  est perforée et traversée par un axe 11 au  tour duquel le cadre peut pivoter. A cette  même extrémité une pièce 3, présentant en  section transversale la forme d'un<B>U</B> renversé  est fixée sur eux. La partie médiane     ca    de  cette pièce 3 est sensiblement plane.  



  La pièce transversale 2 est incurvée laté  ralement et ses extrémités sont coudées ver  ticalement pour venir en prise avec une ex  trémité des pièces 1.  



  Cette pièce transversale 2 supporte, en  sa partie médiane, une pièce 12' dont les deux  extrémités 12 sont coudées à angles droits,  de manière à être sensiblement verticales et  à prendre appui sur l'extrémité inférieure de  ressorts 13. L'autre extrémité     de'ces    ressorts  est reliée à un point fixe par des pattes 14.  



  La partie. antérieure du cadre est donc  pivotée et la partie postérieure suspendue  d'une manière élastique.      Deux anneaux 4, placés à une petite dis  tance de la pièce transversale 2, sont dis  posés symétriquement par rapport à l'axe  longitudinal de la selle.  



  Des organes élastiques constitués par des  ressorts à boudin 5 relient ces anneaux 4 à  la partie     supérieure    de la pièce transversale  2. Un ressort 7 les relie entre eux. Des res  sorts 6, fixés sur la pièce 3, relient les an  neaux 4 à cette pièce. Deux ressorts 8 re  lient les deux anneaux à un même ressort  9 fixé sur la partie médiane a, de la pièce 3.  



  Les     anneaux    4, les ressorts 5, 6, 7, 8 et  9 sont situés     pratiquement    dans un même  plan.  



  Un ressort 10 relie chaque anneau 4 à  la pièce voisine l.. Ces ressorts 10 ne sont  pas dans le même plan que les anneaux. Ces  organes sont disposés de telle façon que les  efforts tendent à être répartis uniformément  sur les organes élastiques et en vue de trans  mettre uniformément les réactions de la selle  au passager par toute la surface de cette  dernière.  



  Dans la forme d'exécution représentée à  la     fig.    2, le cadre est constitué, comme dans  la première forme d'exécution, par deux pièces  latérales perforées à leurs extrémités     arrté-          rieures    et réunies à leurs extrémités posté  rieures par une pièce transversale. Les fers  plats 1 constituant les pièces latérales sont  posés de champ et ne sont pliés qu'à leurs  extrémités, pour venir se fixer, comme dans  la foi-me d'exécution décrite, à leur partie  antérieure, sur la pièce 3, à section trans  versale en forme de<B>U,</B> à leur partie posté  rieure sur la pièce transversale 2. Cette der  nière est analogue à celle déjà décrite.  



  Les extrémités de la pièce transversale  2     supportent    les deux bouts d'une tige 12'  munie de deux bras 12 sensiblement verti  caux prenant appui sur des ressorts de sus  pension 13.  



  Comme dans la première forme d'exécu  tion, deux anneaux 4 sont reliés entre eux, à  la pièce transversale 2 et à la pièce 3 par  des organes élastiques constitués par des  ressorts.    Par contre, le,     anneaux    ne sont pas reliés  aux pièces latérales 1. A chaque extrémité  de la partie supérieure de la pièce transver  sale 2, un ressort 15 est fixé par une de ses  extrémités, l'autre étant fixée aux ressorts  b et c reliant l'anneau voisin 4 à la pièce 3.  Les ressorts b et c sont connectés tous deux  au ressort 15.  



  Ces ressorts et ces     anneaux    sont situés  pratiquement dans un même plan. Ces or  ganes sont disposés en vue d'atteindre le  même but que dans la première forme d'exé  cution.  



  Dans la troisième forme d'exécution,     fig.3,     le cadre est semblable au cadre de la deuxième  forme décrite. Les anneaux et les ressorts les  reliant au cadre et à la pièce 3 ont une dis  position analogue. Cette selle comporte deux  fers plats 16, disposés de champ et pliés de  telle manière que sur toute leur longueur,  excepté leur extrémité postérieure, les grandes  faces soient planes. L'extrémité antérieure  des fers 16 est articulée sur le cadre. Ces  fers 16 portent un dispositif de fixation de la  selle. Un boulon 17 relie les fers 1 du cadre,  la pièce 3 en forme de<B>U</B> et les fers 16. Une  douille d'écartement 18, placée autour du  boulon 17, maintient constante la distance  des pièces assemblées     (fig.    3 et 4).  



  Les extrémités postérieures des fers 16  sont tordues de façon à pouvoir se fixer au  moyen d'un boulon 20 sur une pièce trans  versale 19 disposée horizontalement et de  manière à supporter l'extrémité d'un ressort  21 reliant la pièce transversale 2 du cadre  à cette membrure, ce ressort     étant    maintenu  en place à sa partie inférieure par le bou  lon 20.  



  La pièce     transversale    19 de la membrure  est constituée par un fer plat.  



  Dans les formes d'exécution décrites, la  position des anneaux est telle que ceux-ci  correspondent aux parties par lesquelles le  passager prend appui sur le siège.  



  Le     nombre    des anneaux, leur position et  leur forme pourraient être     différents    de ceux  décrits.      Les organes élastiques pourraient ne pas  être des ressorts à boudin, leur nombre et  leur disposition pourraient ne pas être les       mimes    que ceux représentés au dessin.



  Saddle. The object of the invention is a saddle for cycles, motorcycles, etc., comprising a metal frame, rings and elastic members connecting these rings to each other and to the frame, "the whole being arranged with a view to uniformly leaving. the forces on the elastic members and uniformly transmit the reactions of the saddle to the passenger through the entire surface of the latter.



  The appended drawing represents schematically and by way of example three embodiments of the object of the invention.



  Fig. 1 is a perspective view of a first embodiment; Fig. 2 a perspective view of a second embodiment, FIG. 3 a perspective view of a third embodiment, FIG. 4; ' a detail view relating to the latter embodiment, on a larger scale.



  In fig. 1 the frame of the saddle is constituted by two lateral metal parts 1 fixed at their rear part to a transverse part 2. The parts 1 and the transverse part 2 are constituted by flat irons placed in the field. These parts 1 are folded in such a way that their large faces are flat. The front end of these parts is perforated and traversed by a pin 11 around which the frame can pivot. At this same end a part 3, having in cross section the shape of an inverted <B> U </B> is fixed to them. The middle part ca of this part 3 is substantially flat.



  The cross piece 2 is curved laterally and its ends are bent vertically to engage with one end of the pieces 1.



  This transverse part 2 supports, in its middle part, a part 12 ′, the two ends 12 of which are bent at right angles, so as to be substantially vertical and to bear on the lower end of springs 13. The other end of 'these springs is connected to a fixed point by tabs 14.



  The part. the front part of the frame is therefore pivoted and the rear part suspended in an elastic manner. Two rings 4, placed at a small distance from the transverse part 2, are arranged symmetrically with respect to the longitudinal axis of the saddle.



  Elastic members constituted by coil springs 5 connect these rings 4 to the upper part of the transverse part 2. A spring 7 connects them together. Spells 6, fixed on part 3, connect the rings 4 to this part. Two springs 8 connect the two rings to the same spring 9 fixed on the middle part a, of part 3.



  The rings 4, the springs 5, 6, 7, 8 and 9 are located practically in the same plane.



  A spring 10 connects each ring 4 to the neighboring part 1. These springs 10 are not in the same plane as the rings. These members are arranged in such a way that the forces tend to be distributed uniformly over the elastic members and with a view to uniformly transmitting the reactions of the saddle to the passenger over the entire surface of the latter.



  In the embodiment shown in FIG. 2, the frame is formed, as in the first embodiment, by two side pieces perforated at their rear ends and joined at their rear ends by a transverse piece. The flat bars 1 constituting the side pieces are placed on the field and are only bent at their ends, to be fixed, as in the faith-me of the execution described, at their anterior part, on part 3, in section transverse in the form of <B> U, </B> to their posterior part on the transverse part 2. The latter is similar to that already described.



  The ends of the transverse part 2 support the two ends of a rod 12 'provided with two substantially vertical arms 12 bearing on suspension springs 13.



  As in the first embodiment, two rings 4 are connected to one another, to the transverse part 2 and to the part 3 by elastic members constituted by springs. On the other hand, the rings are not connected to the side parts 1. At each end of the upper part of the transverse part 2, a spring 15 is fixed by one of its ends, the other being fixed to the springs b and c connecting the neighboring ring 4 to part 3. The springs b and c are both connected to the spring 15.



  These springs and these rings are located practically in the same plane. These organs are arranged with a view to achieving the same goal as in the first embodiment.



  In the third embodiment, fig.3, the frame is similar to the frame of the second form described. The rings and the springs connecting them to the frame and to the part 3 have a similar position. This saddle comprises two flat irons 16, arranged field and folded in such a way that over their entire length, except their rear end, the large faces are flat. The front end of the irons 16 is articulated on the frame. These irons 16 carry a device for fixing the saddle. A bolt 17 connects the irons 1 of the frame, the <B> U </B> shaped part 3 and the irons 16. A spacer sleeve 18, placed around the bolt 17, keeps the distance of the assembled parts constant ( fig. 3 and 4).



  The rear ends of the irons 16 are twisted so as to be able to be fixed by means of a bolt 20 on a transverse part 19 arranged horizontally and so as to support the end of a spring 21 connecting the transverse part 2 of the frame to this frame, this spring being held in place at its lower part by the bolt 20.



  The transverse part 19 of the frame consists of a flat bar.



  In the embodiments described, the position of the rings is such that they correspond to the parts by which the passenger leans on the seat.



  The number of rings, their position and their shape could be different from those described. The elastic members may not be coil springs, their number and their arrangement may not be the same as those shown in the drawing.
