DEMONTE-PNEU
La présente invention concerne un démonte-pneu du type comprenant un corps terminé par un crochet.TIRE LEVER
The present invention relates to a tire changer of the type comprising a body terminated by a hook.
Comme on le sait, cet outil est destiné, en coopération avec un ou deux autres du même genre, à extraire un pneu, notamment de bicyclette ou de motocyclette, de sa jante, totalement lorsque ce pneu doit être remplacé, ou partiellement lorsqu'$1 doit être réparé après crevaison. As is known, this tool is intended, in cooperation with one or two others of the same kind, to extract a tire, in particular of bicycle or motorcycle, from its rim, completely when this tire needs to be replaced, or partially when $ 1 must be repaired after puncture.
Dans ce dernier cas, il n'est nécessaire d'extraire de la jante qu'un seul des flancs du pneu. Pour ce faire, on introduit le crochet du démonte-pneu entre la tringle délimitant le flanc du pneu et la jante, et par un effet de levier on fait sortir de la jante la partie correspondante dudit flanc. Après basculement, on peut maintenir le levier en place grâce à une fente prévue à l'extrémité opposée à celle qui comporte le crochet, en engageant cette fente sur le rayon le plus voisin de la roue. Les mêmes opérations, répétées au voisinage du précédent démonte-pneu, avec au moins deux autres démonte-pneus, permettent en général l'extraction du flanc du pneu sur une longueur suffisante pour qu'ensuite le flanc puisse être entièrement extrait de la jante à la main, suite à quoi on peut retirer la chambre à air pour la réparer.In the latter case, it is only necessary to extract from the rim one of the sidewalls of the tire. To do this, the hook of the tire lever is introduced between the bead wire delimiting the sidewall of the tire and the rim, and by means of a lever effect, the corresponding part of said sidewall comes out of the rim. After tilting, the lever can be held in place thanks to a slot provided at the end opposite to that which includes the hook, by engaging this slot on the spoke closest to the wheel. The same operations, repeated in the vicinity of the previous tire changer, with at least two other tire changers, generally allow the extraction of the sidewall of the tire over a sufficient length so that the sidewall can be completely removed from the rim at hand, after which the inner tube can be removed for repair.
Lorsque l'on crève à cause d'un silex ou d'un petit morceau de verre ou d'acier, il est important de l'extraire du pneu avant de remettre la chambre à air en place, faute de quoi on pourrait crever à nouveau la chambre dès après son remontage, en la regonflant. When you die because of a flint or a small piece of glass or steel, it is important to remove it from the tire before putting the inner tube back in place, otherwise you could puncture. new the room immediately after reassembly, by re-inflating it.
Le but de la présente invention est de faciliter cette opération, et à cet effet un démonte-pneu conforme à l'invention est caractérisé en ce qu'il comporte un logement pour l'insertion d'un extracteur en forme de pointe, cet extracteur permettant l'enlèvement de l'objet ayant causé la crevaison, tel qu'un silex ou tout autre objet coupant ou perforant de petites dimensions et propre à rester inclus dans l'épaisseur du pneu. Grâce à une extrémité pointue de l'extracteur, que l'utilisateur aura immédiatement sous la main, il pourra de la sorte extraire commodément ce type d'objet, sans risquer de se blesser, et remettre ensuite l'extracteur dans son logement, ce qui évitera de le perdre. The purpose of the present invention is to facilitate this operation, and for this purpose a tire lever according to the invention is characterized in that it comprises a housing for the insertion of a tip-shaped extractor, this extractor allowing the removal of the object causing the puncture, such as a flint or any other cutting or perforating object of small dimensions and suitable for remaining included in the thickness of the tire. Thanks to a pointed end of the extractor, which the user will have immediately at hand, he can in this way conveniently extract this type of object, without risking injury, and then put the extractor back in its housing, this who will avoid losing it.
De préférence, on utilise pour ce démonte-pneu de la matière plastique armée, étant entendu cependant que l'extracteur pourrait aussi être constitué d'une simple pointe de menuisier. Preferably, for this tire lever, reinforced plastic is used, it being understood however that the extractor could also consist of a simple carpenter's point.
Avantageusement, la matière plastique est une résine polyamide armée de fibres de verre, mais l'extracteur peut aussi être en polyacétal. Advantageously, the plastic material is a polyamide resin reinforced with glass fibers, but the extractor can also be made of polyacetal.
Un jeu de deux ou trois démonte-pneus étant empilé, on pourra prévoir de n'équiper d'un extracteur qu'un seul d'entre eux, avantageusement celui du dessus, puisqu'il n'est pas nécessaire de disposer de plusieurs extracteurs pour un seul Jeu de démonte-pneus. A set of two or three tire levers being stacked, provision may be made for equipping only one of them with an extractor, advantageously the one above, since it is not necessary to have several extractors for a single set of tire changers.
Un mode d'exécution de l'invention est décrit cidessous avec référence aux figures du dessin annexé dans lequel
- la figure 1 est une vue de face d'un démonte-pneu conforme à l'invention, l'extracteur étant retiré de son logement
- la figure 2 est une vue de dessus
- la figure 3 est une vue de dessous
- la figure 4 est une vue de gauche ; et
- la figure 5 est une vue de face montrant deux démonte-pneus accouplés.An embodiment of the invention is described below with reference to the figures of the accompanying drawing in which
- Figure 1 is a front view of a tire changer according to the invention, the extractor being removed from its housing
- Figure 2 is a top view
- Figure 3 is a bottom view
- Figure 4 is a left view; and
- Figure 5 is a front view showing two coupled tire levers.
Dans les différentes figures, chaque démonte-pneu comporte un corps 1, un crochet d'extrémité 2 et, à l'opposé, une extrémité relevée 3 à fente 4, le corps servant à saisir le démonte-pneu et les autres parties ayant la fonction décrite plus haut. Un logement longitudinal 5, débouchant à la surface supérieure du corps 1, permet l'insertion, par un engagement à force, d'un extracteur 6 à extrémité pointue 7. In the various figures, each tire changer has a body 1, an end hook 2 and, on the other hand, a raised end 3 with a slot 4, the body serving to grip the tire changer and the other parts having the function described above. A longitudinal housing 5, opening onto the upper surface of the body 1, allows the insertion, by force engagement, of an extractor 6 with a pointed end 7.
Le corps et l'extracteur peuvent être en une résine polyamide, armée par exemple de fibres de verre pour en augmenter la rigidité, mais l'extracteur peut aussi être en polyacétal. The body and the extractor can be made of a polyamide resin, reinforced for example with glass fibers to increase its rigidity, but the extractor can also be made of polyacetal.
Le corps 1 de chaque démonte-pneu peut comporter sur une face une cavité ronde 8 et à l'opposite un plot de forme complémentaire 9, ce qui permet d'empiler un nombre quelconque de démonte-pneus en les accouplant deux à deux, comme montré à la figure 5. The body 1 of each tire changer can have a round cavity 8 on one side and a complementary shaped stud 9 opposite, which allows any number of tire levers to be stacked by coupling them two by two, as shown in figure 5.
