Du fait du nouveau concept du pneumatique selon l'invention, les jantes traditionnelles ne sont pas adaptées à ce pneumatique et par conséquent, un autre objet de l'invention est une jante pouvant coopérer avec un pneumatique selon l'invention.Due to the new concept of the tire according to the invention, the traditional rims are not adapted to this tire and therefore another object of the invention is a rim that can cooperate with a tire according to the invention.
Ainsi, un autre objet de l'invention est une jante pour cycle, comportant un élément annulaire présentant une gorge périphérique extérieure apte à recevoir un pneumatique de cycle, ledit élément annulaire étant apte à être relié par des moyens de liaison à un moyeu central d'une roue de cycle, la jante selon l'invention comporte dans ladite gorge des trous adaptés pour recevoir les crampons d'un pneumatique tel que défini ci-dessus.Thus, another object of the invention is a cycle rim, comprising an annular element having an outer peripheral groove adapted to receive a cycle tire, said annular element being able to be connected by means of connecting means to a central hub of a cycle wheel, the rim according to the invention comprises in said groove holes adapted to receive the studs of a tire as defined above.
Selon d'autres caractéristiques de la jante selon l'invention : - lesdits trous sont complémentaires desdits crampons ;According to other characteristics of the rim according to the invention: said holes are complementary to said crampons;
- lesdits moyens de liaison sont des rayons filiformes et ledit élément annulaire comporte sur sa périphérie intérieure des trous de fixation des rayons, le nombre de trous dans ladite gorge aptes à recevoir lesdits crampons étant au moins égal au double du nombre de trous de fixation des rayons. Encore un autre objet de l'invention est une roue de cycle comportant le pneumatique et la jante selon l'invention.said connecting means are filiform radii and said annular element has radially fixing holes on its inner periphery, the number of holes in said groove capable of receiving said studs being at least equal to twice the number of holes for fixing the radii. rays. Yet another object of the invention is a cycle wheel comprising the tire and the rim according to the invention.

Dans les figures, les éléments identiques ou équivalents porteront les mêmes signes de référence. Un premier mode de réalisation de l'invention sera maintenant décrit en référence aux figures 1 à 4.In the figures, identical or equivalent elements will bear the same reference signs. A first embodiment of the invention will now be described with reference to FIGS. 1 to 4.
Le pneumatique 1 comporte une carcasse tubulaire 2 formant une enveloppe sensiblement circulaire apte à ceinturer une chambre à air (non représentée) prévue dans le volume intérieur 3 de la carcasse. La carcasse 2 est sur sa périphérie extérieure pourvue d'une chape 4 formant bande de roulement et présente une fente circulaire 5 s'étendant sur toute sa périphérie intérieure.The tire 1 comprises a tubular carcass 2 forming a substantially circular envelope adapted to surround an air chamber (not shown) provided in the interior volume 3 of the carcass. The carcass 2 is on its outer periphery provided with a clevis 4 forming a tread and has a circular slot 5 extending over its entire inner periphery.
Le pneumatique 1 est également sur toute sa périphérie intérieure pourvu de deux semelles continues 6, 7 qui s'étendent sur toute la longueur des bords de la fente 5 en refermant pratiquement la fente 5 de la carcasse. Les différences entre les figures 1 et 2 viennent de ce que la figure 1 se rapproche davantage du mode de fabrication d'un pneumatique traditionnel et de ce que la figure 2 se rapproche davantage du mode de fabrication, le plus souvent utilisé, pour les boyaux traditionnels.The tire 1 is also on its entire inner periphery provided with two continuous soles 6, 7 which extend over the entire length of the edges of the slot 5 substantially closing the slot 5 of the carcass. The differences between FIGS. 1 and 2 are that FIG. 1 is closer to the manufacturing method of a conventional tire and that FIG. 2 is closer to the most commonly used method of manufacturing for the intestines. traditional.
La figure 1 fait apparaître une tringle 8 autour de laquelle les fils (non représentés) de la carcasse 2 se retournent.Figure 1 shows a rod 8 around which the son (not shown) of the carcass 2 are turned over.
Les différentes parties du pneumatique, carcasse 2, chape 4, tringle 8 et semelles 6, 7 sont préfabriqués et solidarisées par vulcanisation.The various parts of the tire, carcass 2, yoke 4, rod 8 and flanges 6, 7 are prefabricated and secured by vulcanization.
La valve de chambre à air n'est pas représentée ; elle est de type intérieur et semblable à celles utilisées par les vessies des ballons. Cette valve est implantée le long de la périphérie intérieure du pneumatique 1.The air valve is not shown; it is of the internal type and similar to those used by the bladders of the balloons. This valve is located along the inner periphery of the tire 1.
La figure 2 ne montre pas de tringle. Les différentes parties du pneumatique 1 sont ici solidarisées par coutures. La figure fait apparaître deux coutures continues 9 qui contribuent à rendre solidaires semelles 6, 7 et carcasse 2. Les coutures 9 sont des coutures définitives auxquelles on n'a pas à toucher pour réparer le pneumatique.Figure 2 does not show a rod. The different parts of the tire 1 are here secured by seams. The figure shows two continuous seams 9 which contribute to make soles 6, 7 and carcass 2 integral. The seams 9 are definitive seams which are not touched to repair the tire.
Le pneumatique 1 est monté sur jante de cycle 10 constituée par un élément annulaire présentant une gorge périphérique extérieure 12 qui est définie entre deux lèvres 13, 14. La gorge 12 reçoit le pneumatique 1 dont les semelles 6, 7 reposent entièrement contre la gorge. Le pneumatique 1 selon l'invention présente des protubérances 15 qui, implantées sur la surface extérieure du pneumatique, sont en contact avec la jante 10. Dans ce premier mode de réalisation, les protubérances sont sensiblement cylindriques et sensiblement dirigées vers l'axe de roue.The tire 1 is mounted on a cycle rim 10 constituted by an annular element having an outer peripheral groove 12 which is defined between two lips 13, 14. The groove 12 receives the tire 1 whose sole 6, 7 lie entirely against the groove. The tire 1 according to the invention has protuberances 15 which, implanted on the outer surface of the tire, are in contact with the rim 10. In this first embodiment, the protuberances are substantially cylindrical and substantially directed towards the wheel axle. .
Ces protubérances appelées crampons dans la description qui suivra sont proches les unes des autres et régulièrement réparties tout le long de la périphérie intérieure du pneumatique 1.These protuberances called crampons in the description that will follow are close to each other and regularly distributed all along the Inner periphery of the tire 1.
Les crampons 15 sont destinés à venir se loger dans autant de trous circulaires 16 percés dans la gorge 12 de la jante 10.The crampons 15 are intended to be housed in as many circular holes 16 drilled in the groove 12 of the rim 10.
On sait que les gorges traditionnelles destinées aux boyaux sont déjà percées pareillement afin de permettre la présentation des écrous de rayons. Il va de soi qu'avec un pneumatique selon l'invention le nombre et le diamètre de ces trous 16 seront adaptés aux crampons 15 de ce pneumatique.It is known that the traditional grooves for gutters are already drilled similarly to allow the presentation of the spoke nuts. It goes without saying that with a tire according to the invention the number and the diameter of these holes 16 will be adapted to the crampons 15 of this tire.
On conçoit déjà que les crampons 15, prisonniers des trous 16 de la jante 10, interdisent tout déplacement longitudinal ou transversal du pneumatique 1 sur la jante et que le collage traditionnel des boyaux n'a plus de raison d'être avec un pneumatique selon l'invention.It is already conceivable that the studs 15, trapped in the holes 16 of the rim 10, prohibit any longitudinal or transverse displacement of the tire 1 on the rim and that the traditional gluing of the hoses no longer has any reason to be with a tire according to the invention. 'invention.
Dans le mode de réalisation illustré sur les figures 1 à 4, les crampons 15 sont cylindriques, alors que chaque crampon est ici composé de deux demi- crampons 15', 15" sensiblement hémi-cylindriques, placés en position de vis-à- vis sur chacun des bords de la fente 5 du pneumatique 1 (les faces planes des demi-cylindres étant dans le plan moyen du pneumatique), et destinés à occuper deux par deux les trous circulaires 16 percés dans la jante 10 à cet effet.In the embodiment illustrated in FIGS. 1 to 4, the crampons 15 are cylindrical, whereas each crampon is here composed of two semi-crampons 15 ', 15 "that are substantially semi-cylindrical and placed in a position opposite each other. on each of the edges of the slot 5 of the tire 1 (the plane faces of the half-rolls being in the mean plane of the tire), and intended to occupy two by two the circular holes 16 drilled in the rim 10 for this purpose.
De plus, si on considère maintenant un pneumatique 1 présentant une enveloppe 2 qui ceinture entièrement la chambre à air et présente une solution de continuité le long de sa génératrice intérieure, et des crampons constitués de ces demi-crampons 15', 15", il apparaît que ces caractéristiques maintiennent les bords de l'enveloppe en juxtaposition avant et après le gonflage de la chambre à air et ceci, sans avoir eu recours à aucune couture. Comme déjà mentionné, les bords de la carcasse 2 présentent au contact de la jante 10 deux semelles continues 6, 7 disposées à l'extérieur de la carcasse 2 et solidaires de cette dernière. Ces semelles 6, 7 supportent les demi- crampons 15', 15" situés sur le même bord qu'elles. Un rôle important des semelles 6, 7 est d'assurer la transmission des efforts entre la carcasse 2 et les demi-crampons 15', 15". Les semelles sont 6, 7 sont de préférence en caoutchouc et éventuellement renforcé dans la mesure du nécessaire. Chaque semelle 6, 7 et les demi-crampons 15' respectivement 15" qu'elle supporte constituent une seule pièce qui a été préfabriquée et solidarisée avec la carcasse 2.In addition, if we now consider a tire 1 having an envelope 2 which completely surrounds the inner tube and has a solution of continuity along its inner generatrix, and crampons consisting of these half-crampons 15 ', 15 ", it It appears that these characteristics hold the edges of the envelope in juxtaposition before and after inflation of the inner tube and this, without having resorted to any seam As already mentioned, the edges of the carcass 2 have in contact with the rim Two continuous soles 6, 7 disposed outside the carcass 2 and integral with the latter 2. These flanges 6, 7 support the half crampons 15 ', 15 "located on the same edge as they. An important role of the soles 6, 7 is to ensure the transmission of forces between the carcass 2 and the half-crampons 15 ', 15 ".The soles are 6, 7 are preferably made of rubber and possibly reinforced to the extent necessary. Each sole 6, 7 and the half cramps 15 'respectively 15 "it supports constitute a single piece which has been prefabricated and secured to the carcass 2.
Les figures 5 et 6 d'une part, 7 et 8 d'autre part montrent, tout comme les figures 1 et 2, deux types de pneumatiques différents. Les coupes transversales des figures 5 et 7 ont été faites en partie courante, les crampons n'y apparaissent pas. Les coupes transversales des figures 6 et 8 ont été faites au droit d'un crampon 15.Figures 5 and 6 on the one hand, 7 and 8 on the other hand show, just like Figures 1 and 2, two different types of tires. The cross sections of Figures 5 and 7 were made in the current part, the crampons do not appear. The cross sections of Figures 6 and 8 were made to the right of a crampon 15.
En partie basse des figures 5 à 8, on reconnaît le profil de la jante 10, ses lèvres 13, 14 et sa gorge 12 percée de trous circulaires 16 dont les axes sont dans le plan médian de la jante. Ces trous sont équidistants.In the lower part of Figures 5 to 8, there is the profile of the rim 10, its lips 13, 14 and its groove 12 with circular holes 16 whose axes are in the median plane of the rim. These holes are equidistant.
Il apparaît que ce type de jante est facile à réaliser à partir d'un tube en alliage léger ou en fibres de carbone. Le profil est d'un type traditionnel et les trous 16 ne diffèrent pas de ceux que l'on perce habituellement pour le passage des écrous de rayons.It appears that this type of rim is easy to make from a light alloy tube or carbon fiber. The profile is of a traditional type and the holes 16 do not differ from those which are usually pierced for the passage of the spoke nuts.
A titre d'exemple, ces trous 16 sont au nombre de 72 et leur diamètre est de 13 mm. Un diamètre en fond de gorge de 624 mm fait apparaître une distance voisine de 27 mm entre les axes des trous 16. Une roue de 24 rayons comme une roue de 18 rayons sont bien adaptées aux 72 trous ; on sait que ces rayonnages sont souvent utilisés pour les roues de cycles de compétition.By way of example, these holes 16 are 72 in number and their diameter is 13 mm. A diameter at the bottom of the groove 624 mm shows a distance of about 27 mm between the axes of the holes 16. A wheel of 24 spokes like an 18-spoke wheel are well adapted to the 72 holes; we know that these shelves are often used for competition wheels.
En partie haute des figures 5 à 8, on reconnaît un pneumatique 1 qui ceinture entièrement la chambre à air et qui présente une solution de continuité le long de sa périphérie intérieure.In the upper part of Figures 5 to 8, there is a tire 1 which completely surrounds the air chamber and which has a solution of continuity along its inner periphery.
Le long de chaque bord, les demi-crampons 15', 15" sont régulièrement répartis ; les demi-crampons des deux bords sont placés en vis-à-vis ; deux demi- crampons 15', 15" en vis-à-vis occupent un même trou 16.Along each edge, the half-crampons 15 ', 15 "are regularly distributed, the half-crampons of the two edges are placed facing each other, two semi-crampons 15', 15" facing each other. occupy the same hole 16.
Selon une autre caractéristique de l'invention qui apparaît sur ces figures, des bagues 17 sensiblement cylindriques sont prévues pour être associées aux crampons 15 afin assembler deux par deux les demi-crampons 15', 15" avant de présenter le pneumatique 1 sur sa jante 10, après avoir introduit la chambre à air dans son enveloppe 2. Ainsi les bords de l'enveloppe sont rendus solidaires au moyen de ces bagues 17.According to another characteristic of the invention which appears in these figures, rings substantially cylindrical 17 are provided to be associated with the crampons 15 to assemble two by two half crampons 15 ', 15 "before presenting the tire 1 on its rim 10, after introducing the inner tube into its envelope 2. Thus the edges of the envelope are rendered secured by means of these rings 17.
Même si ces bagues 17 ne sont pas indispensables, elles sont avantageuses à plusieurs titres :Even if these rings 17 are not essential, they are advantageous for several reasons:
- elles facilitent le montage du pneumatique 1 sur sa jante 10, - elles soulagent la jante 10 en assurant elles-mêmes la tenue aux efforts d'ouverture de l'enveloppe 2 sous l'effet de la pression,- They facilitate the mounting of the tire 1 on its rim 10, - they relieve the rim 10 by ensuring themselves holding the opening forces of the casing 2 under the effect of pressure,
- elles protègent les demi-crampons 15', 15" des bords des trous 16 bruts de perçage et quelque peu tranchants,they protect the half-crampons 15 ', 15 "of the edges of the rough and somewhat sharp cutting holes 16,
-elles sont faciles à retirer et faciles à remettre en place. Ces bagues 17, par exemple métalliques, sont montées suffisamment serrées pour se maintenir en cours de manipulation ; par contre, ce serrage ne résiste pas à l'extrémité d'un tournevis qui donnera au cycliste un accès facile à la chambre à air.they are easy to remove and easy to put back in place. These rings 17, for example metal, are mounted sufficiently tight to hold during handling; on the other hand, this tightening does not resist the end of a screwdriver that will give the cyclist easy access to the tube.
Du côté de la jante, les bagues montrent un léger rétreint 18 qui facilite la mise en place des crampons 15 dans les trous 16 de la jante 10. Les extrémités des crampons 15 sont biseautées de manière à épouser la forme de ce rétreint 18.On the side of the rim, the rings show a slight narrowing 18 which facilitates the establishment of the crampons 15 in the holes 16 of the rim 10. The ends of the crampons 15 are bevelled so as to match the shape of the constriction 18.
Du côté opposé, les bagues 17 sont avantageusement, comme cela est illustré à la figure 10, munies de deux butées 19 sous forme de pattes situées dans le plan médian du pneumatique 1 , et qui sont au contact des semelles 6, 7, ces butées 19 étant arrêtées par les bords des trous 16.On the opposite side, the rings 17 are advantageously, as illustrated in FIG. 10, provided with two stops 19 in the form of tabs situated in the median plane of the tire 1, and which are in contact with the soles 6, 7, these stops 19 being stopped by the edges of the holes 16.
Ces butées 19 maintiennent les bagues prisonnières tant que le pneumatique 1 reste sur la jante 10. Ces butées 19 qui s'escamotent dans des empreintes 20 aménagées à la surface extérieure des semelles 6, 7 (voir figure 11) respectent un contact parfait entre semelles 6, 7 et la gorge 12 dé jante 10. La figure 9 montre une variante avec une butée constituée par une collerette 21 qui vient prendre appui contre le bord du trou 16 de la gorge 12 de la jante 10. Egalement dans ce cas, une empreinte (non représentée), qui alors est circulaire, peut être prévue dans les semelles 6, 7.These stops 19 hold the rings captive as the tire 1 remains on the rim 10. These stops 19 which retract into imprints 20 arranged on the outer surface of the soles 6, 7 (see Figure 11) respect a perfect contact between soles. 6, 7 and the throat 12 de rim 10. Figure 9 shows a variant with a stop constituted by a flange 21 which bears against the edge of the hole 16 of the groove 12 of the rim 10. Also in this case, a imprint (not shown), which then is circular, can be provided in the soles 6, 7.
Dans le mode de réalisation illustré aux figures 5 à 8, les semelles 6 ,7 ne sont pas rigoureusement symétriques : l'une (6) d'elles présente une lèvre continue 22 au contact de la chambre à air et qui recouvre au moins partiellement l'autre semelle 7. Plaquée par la pression de l'air cette lèvre 22 évite le pincement de la chambre à air dans le plan médian du pneumatique.In the embodiment illustrated in FIGS. 5 to 8, the soles 6, 7 are not rigorously symmetrical: one (6) of them has a continuous lip 22 in contact with the inner tube and which at least partially covers the other sole 7. Plated by the pressure of the air this lip 22 prevents the pinching of the air chamber in the median plane of the tire.
Si la roue de cycle est une roue équipée de rayons filiformes, leur nombre est compris le plus souvent entre 12 et 24 pour les roues de vocation sportive.If the cycle wheel is a wheel equipped with filiform spokes, their number is most often between 12 and 24 for sports-oriented wheels.
Ce nombre est insuffisant pour le bon accrochage d'un pneumatique 1 suivant l'invention ; il convient de prévoir un nombre de crampons 15 au moins égal au double du nombre de rayons et par conséquent, la jante 10 destinée à supporter ce pneumatique présentera aussi un nombre de trous de réception 16 des crampons 15 au moins égal au double du nombre de rayons.This number is insufficient for the proper attachment of a tire 1 according to the invention; it is appropriate to provide a number of crampons 15 at least equal to twice the number of spokes and therefore the rim 10 intended to support this tire will also have a number of receiving holes 16 of the cramps 15 at least equal to twice the number of spokes rays.
Les trous les plus faciles à réaliser sont les trous circulaires et une jante 10 percée de trous circulaires 16 sous-entend pour les crampons 15 Ia forme de cylindres à base circulaire ; pourtant le choix de crampons à base elliptique (le grand axe de l'ellipse, sensiblement égal au diamètre du trou, étant placé transversalement) peut être avantageux, car une telle disposition exige moins de précision dans la position longitudinale des trous 16 de la jante 10 puisqu'elle permet un certain jeu dans les sens longitudinal du pneumatique des crampons 15 dans les trous de la jante.The easiest holes to be made are the circular holes and a rim 10 pierced with circular holes 16 implies for the crampons 15 Ia form of cylinders with circular base; yet the choice of elliptical-based spikes (the major axis of the ellipse, substantially equal to the diameter of the hole, being placed transversely) may be advantageous, since such an arrangement requires less precision in the longitudinal position of the holes 16 of the rim 10 since it allows a certain clearance in the longitudinal direction of the tire studs 15 in the holes of the rim.
La figure 12 montre une variante d'un pneumatique selon l'invention pourvu de crampons présentant une forme prismatique et plus précisément dans l'exemple illustré hexagonale, alors que la figure 13 montre une jante 10 dont la gorge 12 est pourvue de trous hexagonaux adaptés pour recevoir les crampons de la figure 12.FIG. 12 shows a variant of a tire according to the invention provided with crampons having a prismatic shape and more precisely in the illustrated hexagonal example, whereas FIG. 13 shows a rim 10 whose groove 12 is provided with adapted hexagonal holes. to receive the crampons of Figure 12.
La figure 14 montre une variante d'un pneumatique selon l'invention pourvu de crampons présentant une forme allongée, à extrémités arrondies, alors que la figure 15 montre une jante 10 dont la gorge 12 est pourvue de trous également allongés adaptés pour recevoir les crampons de la figure 14.FIG. 14 shows a variant of a tire according to the invention provided with crampons having an elongated shape with rounded ends, while FIG. 15 shows a rim 10 whose groove 12 is provided with equally elongated holes adapted to receive the crampons. of Figure 14.
Le même résultat peut être obtenu avec des dispositions différentes des crampons 15. Par exemple, dans le cas d'une enveloppe 2 qui ceinture la chambre à air et qui présente une solution de continuité au voisinage de sa périphérie intérieure, le pneumatique 1 pourra présenter sur l'un et l'autre bords de son enveloppe des crampons 15 destinés à occuper individuellement les trous de la jante qui leur sont destinés.The same result can be obtained with different arrangements of the crampons 15. For example, in the case of a casing 2 which surrounds the air chamber and which has a solution of continuity in the vicinity of its inner periphery, the tire 1 may have on both sides of its envelope crampons 15 for individually occupy the rim holes that are intended for them.
Un premier exemple d'une telle disposition de crampons cylindriques 15 est montré aux figures 16 et 17. Dans cet exemple, une série de crampons 15 est disposée de part et d'autre de la fente 5 de l'enveloppe 2. Les deux séries de crampons s'étendent ainsi parallèlement l'une à l'autre sur la périphérie intérieure du pneumatique. Les crampons de chaque série de crampons 15 sont disposés en position de vis-à-vis par rapport aux crampons de l'autre série de crampons.A first example of such an arrangement of cylindrical studs 15 is shown in FIGS. 16 and 17. In this example, a series of crampons 15 is disposed on either side of the slot 5 of the casing 2. The two series studs thus extend parallel to one another on the inner periphery of the tire. The crampons of each series of crampons 15 are arranged in position vis-à-vis with respect to the crampons of the other series of crampons.
Un deuxième exemple d'une telle disposition de crampons cylindriques 15 est montré aux figures 18 et 19. Egalement dans cet exemple, une série de crampons 15 est disposé de part et d'autre de la fente 4 de l'enveloppe 2. Contrairement au premier exemple, les crampons de chaque série de crampons 15 sont ici décalés dans le sens longitudinal par rapport aux crampons de l'autre série de crampons.A second example of such an arrangement of cylindrical studs 15 is shown in FIGS. 18 and 19. Also in this example, a series of studs 15 is disposed on either side of the slot 4 of the casing 2. first example, the crampons of each series of crampons 15 are here shifted in the longitudinal direction relative to the crampons of the other series of crampons.
Les figures 20 et 21 montrent un autre exemple, toujours dans le cas d'une enveloppe 2 qui ceinture la chambre à air et qui présente une solution de continuité au voisinage de sa génératrice intérieure. Dans ce cas, les bords de l'enveloppe, appelés à se croiser à la manière des pans d'une manteau, sont fort différents. Le bord intérieur au contact de la chambre à air présente des crampons cylindriques 15 destinés à occuper individuellement les trous 16 de la jante 10 qui leur sont destinés. Le bord extérieur au contact de la jante 10 présente des trous 23 sous forme de boutonnières destinées à être enfilées sur les crampons 15 du bord intérieur avant que ceux-ci ne viennent se loger dans les trous 16 de la jante 10.Figures 20 and 21 show another example, still in the case of a casing 2 which surrounds the air chamber and which has a solution of continuity in the vicinity of its inner generator. In this case, the edges of the envelope, called to cross in the manner of the sides of a coat, are very different. The inner edge in contact with the inner tube has cylindrical studs 15 for individually occupying the holes 16 of the rim 10 for them. The outer edge in contact with the rim 10 has holes 23 in the form of buttonholes intended to be threaded on the crampons 15 of the inner edge before they are housed in the holes 16 of the rim 10.
Egalement dans ces exemples, le pneumatique accepte une jante facilement réalisable à partir d'un tube en alliage léger ou en fibres de carbone et les crevaisons sont faciles à réparer par les cyclistes eux-mêmes. Finalement, la figure 22 montre une vue d'ensemble en perspective d'une jante 10 selon l'invention faisant partie d'une roue de cycle 24 montrée sans son pneumatique pour plus de clarté. L'élément annulaire 11 de la jante 10 est relié à un moyeu central 25 de la roue par des moyens de liaison qui ici ont la forme de rayons filiformes schématiquement illustrés qui s'étendent entre le moyeu 25 et des trous de fixation 27 effectués sur la périphérie intérieure de la jante 10. Cette figure montre également les trous 16 prévue dans la gorge 12 de la janteAlso in these examples, the tire accepts a rim easily achievable from a light alloy tube or carbon fiber and punctures are easily repaired by the cyclists themselves. Finally, FIG. 22 shows an overall perspective view of a rim 10 according to the invention forming part of a cycle wheel 24 shown without its sound. pneumatic for clarity. The annular element 11 of the rim 10 is connected to a central hub 25 of the wheel by connecting means which here have the form of schematically illustrated filiform radii which extend between the hub 25 and fixing holes 27 made on the inner periphery of the rim 10. This figure also shows the holes 16 provided in the groove 12 of the rim
10 pour recevoir les crampons 15 du pneumatique. Comme déjà mentionné, le nombre de ces trous 16 est au moins égal au double du nombre de trous de fixation 27 des rayons 26.10 to receive the crampons 15 of the tire. As already mentioned, the number of these holes 16 is at least equal to twice the number of fixing holes 27 of the spokes 26.
On conçoit que le pneumatique 1 au complet a pu être préassemblé en atelier de fabrication, qu'il a été commercialisé préassemblé, qu'il a été facile à monter sur sa jante 10 et que, en cas de crevaison, il sera facile à retirer de la jante.It is conceivable that the entire tire 1 could be preassembled in the workshop, it was marketed preassembled, it was easy to mount on its rim 10 and that, in case of puncture, it will be easy to remove of the rim.
L'emplacement du trou de crevaison sera facile à repérer par immersion. Après repérage, les bagues 17 seront retirées au voisinage du trou de crevaison, la chambre à air sera partiellement dégagée, réparée et réintroduite dans son enveloppe. Les bagues 17 une fois replacées, le pneumatique 1 sera facilement remonté sur sa jante 10.The location of the puncture hole will be easy to locate by immersion. After identification, the rings 17 will be removed in the vicinity of the puncture hole, the air chamber will be partially cleared, repaired and reintroduced into its envelope. The rings 17 once replaced, the tire 1 will be easily reassembled on its rim 10.
Le pneumatique selon l'invention est particulièrement bien adapté à une jante réalisable à partir d'un tube en alliage léger ou en fibres de carbone et peut ainsi être remonté sans couture ni collage. II est aussi facile à réparer qu'un pneumatique classique.The tire according to the invention is particularly well suited to a rim achievable from a light alloy tube or carbon fiber and can be reassembled without seam or gluing. It is as easy to repair as a conventional tire.
11 va de soi que les modes de réalisation décrits ne sont pas limitatifs et que l'homme du métier pourra envisager des variantes sans pour autant sortir du cadre de l'invention. It goes without saying that the embodiments described are not limiting and that the art can consider variations without departing from the scope of the invention.
