Abstract

The nut has a cylindrical body (1a) extended through a head and including an inner threading throughout its length, where the body fixes a threaded end of a spoke (2) by screwing. The head is slit along different axis by defining a set of lips (1d) and radial slits (1e), where the lips are radially deformed by a pressing action in order to be hooked to a material constitutive of the threaded end with respect to the spoke. An independent claim is also included for a method of connecting a threaded end of a spoke of a bicycle through a lock nut.

Description

ECROU FREIN POUR RAYONS DE BICYCLETTES ET PROCEDE DE MONTAGE DESDITSBRAKE NUT FOR BICYCLE RAYS AND METHOD OF MOUNTING SAID

RAYONSRAYS

L'invention se rattache au secteur technique de la fixation des rayons de cycles sur les jantes.  The invention relates to the technical sector of the fixing of the rays of cycles on the rims.

Chaque roue de cycles, bicyclettes et similaires comprend environ 20 à 30 rayons qui sont destinés à faire la jonction entre le moyeu de roue et la jante de roue. Ces rayons sont généralement vissés dans des écrous qui sont montés et solidarisés à la jante. Cela représente environ 95 % du marché mondial. Les rayons présentent des extrémités filetées permettant ainsi leur vissage dans chaque écrou correspondant qui présente de manière complémentaire un taraudage.  Each wheel of cycles, bicycles and the like comprises about 20 to 30 spokes which are intended to make the connection between the wheel hub and the wheel rim. These spokes are generally screwed into nuts that are mounted and secured to the rim. This represents about 95% of the world market. The spokes have threaded ends allowing them to be screwed into each corresponding nut which additionally has a tapping.

En pratique, on a constaté qu'il y avait, en fonction des sollicitations, des risques de dévissage des rayons et de nombreux fabricants ont imaginé des solutions pour consolider en quelque sorte l'assemblage et éviter les risques de désolidarisation.  In practice, it was found that there was, depending on the solicitations, the risk of unscrewing the spokes and many manufacturers have devised solutions to consolidate somehow assembly and avoid the risk of separation.

Ces solutions ont été décrites, par exemple, dans le brevet FR 2. 801.247 avec mise en oeuvre d'une déformation du corps du raccord à vis et de son filetage intérieur. L'enseignement du brevet GB 1.000.694 prévoit aussi la mise en oeuvre d'une déformation par compression latérale du raccord à vis dans sa partie corps.  These solutions have been described, for example, in patent FR 2 801.247 with implementation of a deformation of the body of the screw connection and its internal thread. The teaching of the patent GB 1 000 664 also provides for the implementation of a deformation by lateral compression of the screw connection in its body part.

Le brevet EP n 838.352 fait, lui, référence à l'intégration d'un matériau de garnissage dans la tête de l'écrou frein en combinaison avec une liaison par vissage de l'extrémité filetée du rayon par rapport à un taraudage formé sur le raccord.  EP Patent No. 838,352 refers to the integration of a packing material in the head of the brake nut in combination with a screw connection of the threaded end of the spoke with respect to a tapping formed on the connection.

Le brevet EP n 123.519 propose une autre solution avec une 5 différenciation de la dureté des matériaux constitutifs de l'assemblage raccord frein rayon.  EP 123,519 proposes another solution with a differentiation of the hardness of the materials constituting the brake radius connection assembly.

Le brevet FR n 2.774.184 vise un écrou frein dont la tête est arrondie ou sphérique.  FR No. 2,774,184 is aimed at a brake nut whose head is rounded or spherical.

Le brevet EP n 1.169.182 prévoit une autre solution consistant à injecter une dose de colle dans le taraudage de l'écrou frein pour assurer la liaison avec le rayon.  EP No. 1,169,182 provides an alternative solution of injecting a dose of glue into the tapping of the brake nut to ensure the connection with the spoke.

On cite aussi d'autres solutions décrites dans EP 1.479.532, WO 2004/101. 294, WO 2004/054.819, WO 2004/065.138, EP 626.277.  Other solutions described in EP 1.479.532, WO 2004/101 are also mentioned. 294, WO 2004 / 054,819, WO 2004 / 065,138, EP 626,277.

Ainsi qu'il apparaît de cet art antérieur très diversifié dans les solutions retenues et de constructeurs divers, le problème posé est donc d'une acuité importante. Les solutions décrites dans ces différents documents s'avèrent soit complexes et coûteuses, soit offrent une faible fiabilité dans le temps.  As it appears from this very diverse prior art in the solutions selected and various manufacturers, the problem posed is therefore of significant acuity. The solutions described in these various documents prove to be either complex and expensive or offer poor reliability over time.

Le demandeur, qui a une très large expérience de cette question, en étant l'un des principaux fabricants de rayons de bicyclettes dans le monde, a tenté de rechercher une autre solution qui soit simple à mettre en oeuvre et qui présente des garanties d'assemblage et de tenue dans le temps.  The applicant, who has extensive experience in this area, being one of the world's leading manufacturers of bicycle shelves, has tried to find an alternative solution that is simple to implement and that offers guarantees of safety. assembly and holding in time.

Selon une première caractéristique, l'écrou frein pour rayon de roues de bicyclettes et véhicules similaires du type comprenant un corps cylindrique prolongé par une tête et présentant un taraudage intérieur sur toute sa longueur et autorisant la fixation par vissage de l'extrémité filetée d'un rayon est remarquable en ce que ladite tête est fendue selon plusieurs axes en définissant une pluralité de lèvres et de fentes radiales, et en ce que lesdites lèvres sont déformées radialement par action de pressage de sorte à venir s'ancrer dans la matière constitutive de l'extrémité filetée en regard du rayon.  According to a first feature, the brake wheel nut for bicycle wheels and similar vehicles of the type comprising a cylindrical body extended by a head and having an internal thread over its entire length and allowing the threaded end of the threaded end to be screwed on. a ray is remarkable in that said head is split along several axes by defining a plurality of lips and radial slots, and in that said lips are deformed radially by pressing action so as to be anchored in the constituent material of the threaded end opposite the spoke.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures des dessins où : - la figure 1 est une vue en coupe longitudinale d'un assemblage de l'écrou-frein sur rayon, selon l'invention, après ancrage sur l'extrémité filetée du rayon associé, l'écrou-frein étant à six pans standard, - la figure 2 est une vue en coupe longitudinale de l'assemblage de l'écroufrein sur rayon, selon l'invention, après ancrage sur l'extrémité du rayon associé, l'écrou frein étant à six pans court, - la figure 3 est une vue en coupe longitudinale de l'écrou frein, selon l'invention, avec la représentation de la déformation de sa partie tête, - la figure 4 est une vue de dessus, selon la figure 3, - la figure 5 est une vue d'un écrou frein 6 pans en variante selon l'invention, - la figure 6 est une vue en coupe longitudinale, selon l'axe A.A de la figure 5, - la figure 7 est une vue de face de l'écrou frein, selon la figure 6, - la figure 8 est une vue en coupe longitudinale, selon la ligne B.B de la figure 9, de l'écrou-frein après déformation, - la figure 9 est une vue de face de l'écrou-frein, selon la figure 8.  In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings in which: - Figure 1 is a longitudinal sectional view of an assembly of the lock nut; on the spoke, according to the invention, after anchoring on the threaded end of the associated spoke, the brake nut being standard hexagon, - Figure 2 is a longitudinal sectional view of the assembly of the nut on radius according to the invention, after anchoring on the end of the associated spoke, the brake nut being short hexagon, - Figure 3 is a longitudinal sectional view of the brake nut, according to the invention, with the representation the deformation of its head part, - figure 4 is a view from above, according to figure 3, - figure 5 is a view of an alternative hexagon nut brake according to the invention, - figure 6 is a longitudinal sectional view, along the axis AA of FIG. 5, - FIG. 7 is a front view of the brake nut, according to FIG. 6 is a longitudinal sectional view, along the line BB of FIG. 9, of the locknut after deformation; FIG. 9 is a front view of the locknut according to FIG. Figure 8.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures des dessins.  In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings.

L'écrou frein, selon l'invention, est référencé dans son ensemble par (1) et reçoit un rayon (2), ledit écrou frein étant fixé de manière usuelle sur la jante (3) ou roue de bicyclettes et véhicules similaires, quelles qu'en soient les utilisations, course, randonnée, VTT par exemple.  The brake nut, according to the invention, is referenced as a whole by (1) and receives a spoke (2), said brake nut being fixed in the usual manner on the rim (3) or wheel of bicycles and similar vehicles, which whatever the uses, race, hike, mountain bike for example.

L'écrou frein (1) présente un corps (la) cylindrique ou six pans ou carré avec un taraudage (lb) intérieur. La tête (1 c) représentée figures 3 et 4 est en prolongement du corps avec une configuration conique. Cette tête, selon l'invention, est fendue dans des plans axiaux perpendiculaires XX YY pour faire apparaître quatre lèvres (ld). Le taraudage (lb) se prolonge dans la partie axiale de la tête. Le nombre de fentes radiales (le) et donc de lèvres (ld) peut être de quatre, ou de trois, selon une pluralité d'axes radiaux, et en toute hypothèse selon un nombre permettant ensuite la déformabilité des lèvres ainsi qu'il sera précisé par la suite.  The brake nut (1) has a cylindrical or hexagonal or square body (1a) with internal thread (1b). The head (1c) shown in Figures 3 and 4 is in extension of the body with a conical configuration. This head, according to the invention, is split in perpendicular axial planes XX YY to reveal four lips (ld). The tapping (lb) extends in the axial part of the head. The number of radial slots (le) and therefore of lips (ld) can be four, or three, according to a plurality of radial axes, and in any case according to a number which then allows the deformability of the lips as it will be specified later.

Selon la variante des figures 5 à 7, l'écrou frein présente une tête (lc) à 6 pans (1f) se prolongeant ainsi par des lèvres (ld) séparées par des fentes (le) en nombre prédéterminés, quatre, trois ou autres. Dans cette mise en oeuvre également, le taraudage (lb) intérieur de l'écrou est établi et se prolonge dans la tête (1c).  According to the variant of Figures 5 to 7, the brake nut has a head (lc) hexagon (1f) thus extending by lips (ld) separated by slots (the) in predetermined number, four, three or other . In this implementation also, the tapping (lb) inside the nut is established and extends in the head (1c).

Les rayons (2) ont une extrémité filetée (2a) qui est donc engagée dans l'écrou frein par vissage classique.  The spokes (2) have a threaded end (2a) which is therefore engaged in the conventional screw nut.

Selon l'invention, la partie tête au niveau des lèvres (ld) est soumise à une déformation radiale par pressage ou écrasement afin de refermer l'extrémité de l'écrou frein. Les lèvres sont rapprochées les unes des autres et sont ancrées dans l'extrémité filetée du rayon. De par l'effort de serrage, la matière constitutive des lèvres s'incruste dans la partie filetée en regard du rayon contribuant ainsi à sa retenue. La liaison obtenue est ferme de par l'intégration des parties en regard de la tête de l'écrou frein et du rayon.  According to the invention, the head portion at the lips (ld) is subjected to radial deformation by pressing or crushing to close the end of the brake nut. The lips are close together and are anchored in the threaded end of the spoke. Due to the clamping force, the constituent material of the lips is embedded in the threaded portion opposite the radius thus contributing to its retention. The connection obtained is closed by the integration of the parts facing the head of the brake nut and the spoke.

L'invention vise aussi un procédé de liaison de l'extrémité filetée d'un rayon (2) de bicyclettes dans un écrou frein (1) du type présentant un corps (la) avec un taraudage intérieur (lb) et une tête (1c) . Ce procédé consiste en ce qu'on fabrique un écrou frein avec une tête présentant des lèvres (ld) et des fentes radiales, ensuite on procède à la déformation radiale de la tête (1c) par pressage de sorte que lesdites lèvres viennent s'ancrer dans la partie filetée en regard du rayon, et ensuite on introduit et on visse l'extrémité filetée du rayon dans l'écrou-frein qui est emmanchée serrée du fait de ladite déformation.  The invention also relates to a method of connecting the threaded end of a radius (2) of bicycles in a brake nut (1) of the type having a body (la) with an internal thread (lb) and a head (1c ). This method consists in producing a brake nut with a head having lips (ld) and radial slots, then radially deforming the head (1c) by pressing so that said lips are anchored. in the threaded portion opposite the spoke, and then introduced and screwed the threaded end of the spoke in the lock nut which is pressed tight due to said deformation.

La solution est simple à mettre en oeuvre, peu coûteuse. La fiabilité de la liaison est assurée grâce à une force de pression suffisante pour éviter toute liaison superficielle. En d'autres termes, les rayons ne peuvent plus être dévissés ne pouvant plus tourner sur eux-mêmes suite aux sollicitations extérieures. Seul un arrachage du rayon, selon une force substantielle, pourrait permettre la désolidarisation du rayon de l'écrou frein, force qui ne peut être exercée qu'avec l'intervention humaine d'un opérateur. En situation courante d'utilisation, les contraintes extérieures ne permettent pas d'engendrer une telle force.  The solution is simple to implement, inexpensive. The reliability of the connection is ensured by a sufficient pressure force to avoid any superficial binding. In other words, the spokes can no longer be unscrewed can not turn on themselves after external stresses. Only a pulling of the spoke, according to a substantial force, could allow the separation of the radius of the brake nut, a force that can be exerted only with the human intervention of an operator. In current use situation, the external constraints do not allow to generate such a force.

La solution apportée engendre des coûts de fabrication peu élevés et, 5 en tout cas, apparaît largement compétitive en égard des solutions de l'art antérieur. 15 20  The solution provided generates low manufacturing costs and, in any case, appears to be largely competitive with regard to the solutions of the prior art. 15 20
