Description

L'invention concerne un ensemble selle-tigeJe sella de bicyclettes et véhicules similaires. The invention relates to a saddle-rod assemblyI sella of bicycles and similar vehicles.

L'objet de l'invention se rattache notamment au secteur technique des accessoires de cycles et véhicules analogues, t t plus particulièrement des selles et tiges de selles. The object of the invention relates in particular to the technical sector of accessories for cycles and similar vehicles, more particularly saddles and seat posts.

I1 existe de nombreux types de selles et tiges de selles sur le marché. On cite notamment : les selles à armature dont les fils coopèrent avec une tige de selle ou un chariot de tige de selle, les selles incorporant une plaque rigide agencée pour coopérer avec une tige de selle... There are many types of saddles and seat posts on the market. We cite in particular: the saddles with reinforcement whose threads cooperate with a seatpost or a seatpost carriage, the saddles incorporating a rigid plate arranged to cooperate with a seatpost ...

Dans tous les cas, ltextrémité supér-eure de la tige de selle est conformée par forgeage, découpage, emboutissage, ce qui implique des opéraffons d'usinage et un nombre de pièces élevé qui augmentent considérablement le prix de revient et ne permettent pas toujours des règlages intéressants. In all cases, the upper end of the seat post is shaped by forging, cutting, stamping, which involves machining operations and a high number of parts which considerably increase the cost price and do not always allow interesting settings.

C'est pour obvir à ces inconvénients que l'on a conçu l'en- semble selle-tige de selle selon l'invention. It is to overcome these drawbacks that the saddle-seatpost assembly according to the invention has been designed.

Suivant une première caractéristique, ltensemble selle- tige de selle comprend une selle incorporant une carcasse ou os- sature rigide et profilée dont une partie de sa longueur, de pré- férense la partie arrière,présente dans sa partie médiane, une cavité courbe dans le sens longitudinal, à concavité tournée vers le bas pour recevoir à coulissement guidé ltextrémité recourbée d'une tige de selle de section correspondante à la section de la cavité ; la carcasse de la selle et ltextrémité recourbée de la tige de selle étant solidarisées de manière démontable et règlable par tous moyens. According to a first characteristic, the saddle-seatpost assembly comprises a saddle incorporating a rigid and profiled carcass or framework, part of its length, preferably the rear part, present in its median part, a curved cavity in the longitudinal direction, concavity turned downward to receive guided sliding the curved end of a seat post of section corresponding to the section of the cavity; the carcass of the saddle and the curved end of the seatpost being secured in a removable manner and adjustable by any means.

Ces caractéristiques et d'autres encore ressortiront de la description qui suit. These characteristics and others will emerge from the description which follows.

la fiure 5 est une vue en coupe considérée suivant la ligne 5-5 de la figure 4. Figure 5 is a sectional view taken along line 5-5 of Figure 4.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant sous des formes non limitatives de réalisation illustrées aux figures du dessin. In order to make the object of the invention more concrete, it is now described in nonlimiting embodiments illustrated in the figures of the drawing.

la selle S illustrée,est composée d'une carcasse ou ossature 1 rigide, en tôle par exemple,mais non limitativement, d'un matériau de remplissage et d'une enveloppe (illustrés en traits interrompus et repérés en R aux figures 1, 2, 3). the saddle S illustrated, is composed of a rigid carcass or framework 1, of sheet metal for example, but not limited to, of a filling material and of an envelope (illustrated in dashed lines and marked at R in FIGS. 1, 2 , 3).

A titre d'exemple, la carcasse 1 est profilée pour présenter à l'avant un bec la, et à l'arrière un siège lb, avec un double cintrage longitudinal entre ces deux parties. La section transversale, comme on le voit aux figures 2 et 3, est en forme de U, et la partie arrière lb présente dans sa partie médiane une cavité lc emboutie par exemple, de section semi-circulaire par exemple, sur tout ou partie de sa longueur, et de profil concave par rapport à la tige de selle. By way of example, the carcass 1 is profiled so as to present at the front a spout la, and at the rear a seat 1b, with a double longitudinal bending between these two parts. The cross section, as seen in Figures 2 and 3, is U-shaped, and the rear part lb has in its middle part a cavity lc stamped for example, semi-circular section for example, on all or part of its length and concave profile with respect to the seatpost.

Cette cavité lc est destinée à recevoir et à guider la tige de selle 2 qui est avantageusement réalisée dans un tube acier ou en alliage léger, ou matériau plastique, et simplement recourbée en arc de cercle à son extrémité 2a, avec un rayon R1 correspondant au rayon R2 de la cavité (figure 1) pour qu'elle s'y loge convenablement en épousant le profil de la cavité. L'autre extrémité 2b de litige de selle est introduite de manière classique, dans le tube Ti du raccord T2 de selle. Il n'est pas exclu de prévoir d'autres formes en section pour l'extrémité recourbée et la cavité. This cavity lc is intended to receive and guide the seatpost 2 which is advantageously produced in a steel or light alloy tube, or plastic material, and simply bent in an arc of a circle at its end 2a, with a radius R1 corresponding to the radius R2 of the cavity (FIG. 1) so that it fits there properly by conforming to the profile of the cavity. The other end 2b of saddle litigation is introduced in a conventional manner, into the tube Ti of the saddle fitting T2. It is not excluded to provide other shapes in section for the curved end and the cavity.

La fixation entre la carcasse de selle 1 et la tige de selle 2, peut s'opérer de plusieurs manières. The attachment between the seat carcass 1 and the seat post 2 can take place in several ways.

On a illustré à la figure 3 notamr.ent, une fixation préférée quoique non limitative, suivant laquelle un cavalier ou collier ss est conformé pour épouser dans sa partie centrale cintrée ja, la tige de selle 2 et pour être fixé sous la carcasse par ses ailes latérales Lb, au moyen de boulons 4 ou organes similaires traversant la carcasse et les ailes. Illustrated in Figure 3 in particular, a preferred but non-limiting fixing, according to which a rider or collar ss is shaped to match in its central curved part ja, the seatpost 2 and to be fixed under the carcass by its lateral wings Lb, by means of bolts 4 or similar members passing through the carcass and the wings.

On comprend que de cette manière simple, le réglage an;u- laire de la selle par rapport à la tige de selle, s'opes par dévissaffle du cavalier ou collier, afin de faire coulisser la cavité lc de la carcasse par rapport à la tige de selle. It is understood that in this simple way, the annual adjustment of the saddle relative to the seat post, is effected by unscrewing the rider or collar, in order to make the cavity lc of the carcass slide with respect to the saddle stem.

Suivant une autre réalisation illustrée aux figures 4 et 5, la fixation et le règlage angulaire s' opèrent par au moins une, et de préférence deux vis 5 à tête solidaires de la carcasse et traversant avec jeu des luniières 6a exécutées axialement sur les parois opposées de l'extrémité recourbée 6b de la tige de selle 6; l'assemblage stoperant par rondelle et écrou 7, sous la tige de selle. Pour renforcer l'assemblage à ce niveau, on peut prévoir une ouille 8 (traits interrompus), percée d'orifices 8a de passage de La vis, et cintrée comme la tige de selle. According to another embodiment illustrated in Figures 4 and 5, the fixing and the angular adjustment are effected by at least one, and preferably two screws 5 with head secured to the carcass and crossing with play of the luniières 6a executed axially on the opposite walls from the curved end 6b of the seatpost 6; the stopper assembly by washer and nut 7, under the seatpost. To strengthen the assembly at this level, one can provide a lug 8 (broken lines), pierced with holes 8a for the passage of the screw, and bent like the seatpost.

lies avantages ressortent bien de la description, on souligne notamment - T'a fabrication solide et économique de l'ensemble selle-tige de selle, par les formes simples et profilées - Les règlages angulaires rapides et larges ; - La légèreté de l'ensemble - lie nombre réduit de pièces. the advantages clearly emerge from the description, it is emphasized in particular - The solid and economical manufacture of the saddle-saddle assembly, by the simple and streamlined shapes - The quick and wide angular adjustments; - The lightness of the whole - reduces the reduced number of parts.

L'invention ne se limite aucunement à celui de ces modes d'application, non plus qu'à ceux des modes de réalisation de ces diverses parties ayant plus spécialement été indiqués ; elle en embrasse au contraire toutes les variantes. The invention is in no way limited to that of these modes of application, nor to those of the embodiments of these various parts which have been more particularly indicated; on the contrary, it embraces all its variants.
