Abstract

The boot consists of a rigid upper topped by a reinforcing collar that is able to slide and pivot relative to the upper by means of a screw (80) and nut (81) coupling passing through a hole in the upper and a slot in the collar. After the screw and nut have been fixed together the recessed tip (803) of the screw is bent over to form a lip (804) which prevents the coupling from coming undone unless a given torque is applied to it. Both the screw and nut have sockets (805, 813) to receive keys, preferably Allen keys.

Description

La présente invention concerne une chaussure de sport destinée aux pratiques sportives telles que le patin en ligne, le patin à glace, le ski de fond, la randonnée, le snowboard, wake board, etc. Dans la plupart de ces pratiques sportives, les chaussures proposées combinent des parties rigides pour assurer des fonctions de protection et de transmission des efforts, et des parties plus souples pour le confort, l'aération, etc.The present invention relates to a sports shoe intended for sports such as inline skating, ice skating, cross-country skiing, hiking, snowboarding, wake board, etc. In most of these sports, the proposed shoes combine rigid parts to provide protection and transmission functions for efforts, and softer parts for comfort, ventilation, etc.

Dans certaines applications comme le patin, il est connu de proposer une chaussure comportant une ossature rigide comprenant une base de coque sur laquelle est relié selon au moins un axe transversal un élément de collier. Une telle construction en deux parties rigides reliées entre elles a pour avantages, entre autres, d'autoriser une certaine liberté de mouvement du bas de jambe, dans certaines conditions, tout en assurant toujours une protection efficace, une transmission des efforts et de bons appuis lors du patinage.In certain applications such as skating, it is known to offer a shoe with a rigid frame comprising a shell base to which is connected in accordance with minus a transverse axis a collar element. Such a construction in two rigid parts linked together has for advantages, inter alia, of allowing a certain freedom of lower leg movement, under certain conditions, while always ensuring effective protection, transmission of effort and good support during skating.

Avec l'émergence de nouvelles pratiques dans le domaine du patin en ligne comme « l'aggressive », sont apparues de nouvelles exigences en terme de sauts, figures, glissades, etc., qui ont donné naissance à des constructions de chaussures adaptées. Par exemple, les pratiquants veulent pouvoir réaliser des figures acrobatiques lors des sauts ou des glissades sur des rambardes, des barres ou des trottoirs qui exigent une inclinaison latérale importante de la cheville. Dans le même temps, la chaussure doit apporter suffisamment de rigidité dans toutes les directions pour conserver de bons appuis lors du patinage et une protection efficace contre les chocs et aussi en prévention de torsions dangereuses et accidentelles de la cheville.With the emergence of new practices in the field of inline skating as "aggressive", appeared from new requirements in terms of jumps, tricks, slides, etc. which gave rise to shoe constructions adapted. For example, practitioners want to be able to realize acrobatic figures when jumping or sliding on guardrails, bars or sidewalks that require significant lateral inclination of the ankle. In the same time, the shoe should provide enough stiffness in all directions to maintain good support during skating and effective impact protection and also to prevent dangerous and accidental torsion of the ankle.

Une chaussure répondant aux spécificités de la pratique du patin « aggressive » peut donc présenter, de façon avantageuse, un collier recouvrant une partie du bas de jambe qui est relié à une base de coque rigide recouvrant, au moins partiellement, le pied. Des parties plus souples sont généralement associées aux parties rigides, tel qu'un rembourrage interne prenant place à l'intérieur de la coque. Pour assurer ce besoin de laxité transversale, le collier est relié à la base de coque selon deux systèmes d'axes sensiblement transversaux de chaque côté de la chaussure associés à des moyens d'inclinaison transversale, tels que des lumières facilitant le mouvement relatif transversal du collier par rapport à la base de coque.A shoe that meets the specificities of the practice of “aggressive” skate can therefore advantageously present a collar covering a part of the lower leg which is connected to a rigid shell base covering, at least partially, foot. More flexible parts are generally associated to rigid parts, such as internal padding taking place inside the hull. To ensure this need for transverse laxity, the collar is connected to the shell base according to two systems of substantially transverse axes of each side of the shoe associated with tilt means transverse, such as lights facilitating movement transverse relative of the collar relative to the shell base.

Un tel exemple de construction est décrit dans la demande de brevet européenne non encore publiée n° 97119222.4 dont le contenu est incorporé dans la présente demande par référence. Les moyens de liaison, proprement dit du collier sur la base de coque comprennent avantageusement des moyens démontables du type vis/écrou. De tels moyens présentent l'avantage de résister aux efforts importants d'arrachement imposés sur le collier lors de flexions. Pour cela, la longueur de filetage, le diamètre de la tige d'axe, etc., doivent être dimensionnés en conséquence. Ils existent d'autres moyens de fixation mais qui ne donnent pas entièrement satisfaction tels que des rivets qui sont beaucoup moins résistants à l'arrachement. Le moyen de fixation vis/écrou possède aussi l'avantage de rendre le collier interchangeable. En effet, la tendance est à la « customisation » des produits. Certains pratiquants veulent pouvoir adapter des colliers tantôt plus souples, tantôt plus rigides selon leur poids, le type de pratique, ou simplement par souci de réparation du fait que le matériau peut vieillir ou casser à force de sollicitations répétées.Such a construction example is described in the request. of European patent not yet published n ° 97119222.4 whose content is incorporated into this application by reference. The connecting means, proper of the collar on the basis of shell advantageously include removable means of the screw / nut type. Such means have the advantage of resist the significant pullout forces imposed on the collar during bending. For this, the thread length, the diameter of the shaft rod, etc., must be dimensioned Consequently. There are other ways of fixing but not entirely satisfactory such as rivets which are much less resistant to tearing. Way to fixing screw / nut also has the advantage of making the interchangeable collar. Indeed, the trend is towards "Customization" of products. Some practitioners want ability to adapt collars sometimes more flexible, sometimes more rigid according to their weight, the type of practice, or simply for repair of the fact that the material can age or break by force of repeated stresses.

Un des problèmes rencontrés est alors d'éviter un desserrage intempestif du moyen de liaison qui est favorisé par la liberté relative de mouvement du collier par rapport à la base de coque. Il existe des produits du type « frein-filet » qui sont appliqués par vaporisation sur la partie filetée de la vis et qui se plastifient ensuite pour s'opposer au desserrage. Toutefois, on a pu constater que l'efficacité de ces moyens se révèlent tout à fait insuffisante pour prévenir le risque desserrage.One of the problems encountered is then to avoid a untimely loosening of the connecting means which is favored by relative freedom of movement of the collar with respect to the hull base. There are products of the "threadlocker" type which are applied by spraying on the threaded part of the screws and which then plasticize to prevent loosening. However, it has been observed that the effectiveness of these means is prove completely insufficient to prevent risk loosening.

Un autre problème est lié à la difficulté de contrôler l'intensité du serrage tout en conservant des possibilités de mouvements relatifs entre le collier et la coque. En effet, si le serrage est trop fort, on risque de rendre solidaire le collier de la base de coque sans possibilité de mouvement. Si le serrage est trop lâche, le risque de desserrage est fortement augmenté. Il s'avère donc antagoniste de vouloir à la fois sécuriser un serrage sans risque de desserrage et à la fois autoriser un certain jeu pour le glissement des pièces à serrer.Another problem is related to the difficulty of controlling the intensity of the tightening while retaining possibilities of relative movements between the collar and the shell. Indeed, if the tightening is too strong, there is a risk of making the shell base collar with no possibility of movement. Yes the tightening is too loose, the risk of loosening is greatly increased. It is therefore antagonistic to want to secure a tightening without risk of loosening and times allow a certain play for the sliding of the pieces to tighten.

La présente invention a donc pour but de proposer une solution aux problèmes précités.The present invention therefore aims to provide a solution to the above problems.

Pour cela l'invention concerne une chaussure de sport comprenant:

  • une portion de coque rigide assurant le maintien partiel au moins du pied;
  • un collier recouvrant une partie de ladite portion de coque et la prolongeant vers le haut pour un maintien du bas de jambe;
  • au moins un moyen de liaison du collier sur ladite portion de coque comprenant un élément de vis comprenant une partie de tige ayant au moins une portion filetée et un élément complémentaire d'écrou comprenant une portion filetée complémentaire permettant l'engagement de ladite portion de tige caractérisée en ce que,
  • la partie de tige de l'élément de vis comprend une extrémité qui s'engage dans l'élément d'écrou et qui comprend au moins une portion de lèvre bouterollée sur l'élément d'écrou.
    • For this, the invention relates to a sports shoe comprising:
  • a rigid shell portion providing partial support at least for the foot;
  • a collar covering part of said shell portion and extending it upwards to hold the lower leg;
  • at least one means of connecting the collar to said shell portion comprising a screw element comprising a rod part having at least one threaded portion and a complementary nut element comprising a complementary threaded portion allowing the engagement of said rod portion characterized in that,
  • the rod part of the screw element comprises an end which engages in the nut element and which comprises at least one portion of lip snapped onto the nut element.

    • Une telle conception du moyen de liaison permet de prévenir le desserrage de l'élément de vis provoqué par les mouvements répétés du collier par rapport à la base de coque. En revanche, la possibilité existe alors de provoquer volontairement le desserrage en forçant jusqu'à déformation ou rupture de la portion de lèvre en appliquant un couple de desserrage au delà d'un seuil prédéterminé.Such a design of the connecting means makes it possible to prevent loosening of the screw element caused by movements repeated of the collar with respect to the shell base. On the other hand, the possibility then exists of voluntarily provoking the loosening by forcing until deformation or rupture of the lip portion by applying a couple of loosening beyond a predetermined threshold.

    Un autre avantage est qu'il n'est pas nécessaire d'appliquer un couple de serrage trop important pour sécuriser la fixation, et donc, le mouvement entre les pièces continue à être favorisé indépendamment de l'intensité du serrage.Another advantage is that it is not necessary applying too much tightening torque to secure the fixing, and therefore, the movement between the pieces continues to be favored regardless of the intensity of the tightening.

    D'autres caractéristiques et avantages de l'invention ressortiront de la description des figures qui suivent et dans lesquelles:

  • La figure 1 est une vue en perspective arrière d'un patin en ligne comprenant une chaussure selon l'invention.
  • La figure 2 montre une vue éclatée du détail de l'assemblage de la chaussure selon l'invention.
  • La figure 3 est une vue en coupe selon A-A de la chaussure représentée à la figure 1 au moment du montage du collier sur la base de coque.
  • La figure 4 est une vue en coupe selon A-A de la chaussure représentée à la figure 1 dans une configuration opérationnelle.
  • La figure 5 est une vue en coupe selon A-A de la chaussure représentée à la figure 1 dans une opération ultérieure de démontage du collier.
    • Other characteristics and advantages of the invention will emerge from the description of the figures which follow and in which:
  • Figure 1 is a rear perspective view of an inline skate comprising a shoe according to the invention.
  • Figure 2 shows an exploded view of the detail of the assembly of the shoe according to the invention.
  • Figure 3 is a sectional view along AA of the shoe shown in Figure 1 at the time of mounting the collar on the shell base.
  • Figure 4 is a sectional view along AA of the shoe shown in Figure 1 in an operational configuration.
  • Figure 5 is a sectional view along AA of the shoe shown in Figure 1 in a subsequent operation of removing the collar.

    • L'invention est illustrée dans le cadre d'un patin en ligne 1 du type « aggressive » illustré à la figure 1 dans la mesure où il s'agit, à la connaissance du demandeur, du mode de réalisation préféré dans lequel l'invention présente le plus d'avantages reconnus. Toutefois, l'invention ne saurait se limiter à ce seul type d'application mais peut recouvrir d'autres types de produits incorporant une chaussure technique munie de parties rigides assemblées entre elles et dans lesquelles les parties rigides sont destinées à se déplacer relativement l'une par rapport à l'autre lors de sollicitations de la jambe ou du pied.The invention is illustrated in the context of an inline skate 1 of the “aggressive” type illustrated in FIG. 1 to the extent where, as far as the applicant is aware, this is the method of preferred embodiment in which the invention presents the most recognized benefits. However, the invention cannot be limit to this type of application only but can cover other types of products incorporating a technical shoe provided with rigid parts assembled together and in which the rigid parts are intended to move relatively to each other when stressed leg or foot.

    Le patin en ligne de la figure 1 comprend une chaussure 2 rapportée sur un châssis 3 muni d'une série de roues 4 orientées selon un alignement longitudinal. Le châssis 3 comprend des flasques latéraux 30, 31 reliés entre eux par des ponts 32, 33 localisés respectivement à l'avant et à l'arrière de la chaussure. Les ponts ont des portions s'étendant latéralement au delà des flasques latéraux de part et d'autre de ceux-ci, de façon à offrir des surfaces d'appui suffisantes avec la semelle 20 de la chaussure avec laquelle ils s'assemblent. L'assemblage du châssis sur la chaussure peut se faire selon tout moyen de fixation approprié tels que des vis, rivets, collage, soudage, emboítement ou toute combinaison appropriée de ces moyens.The inline skate of FIG. 1 comprises a shoe 2 attached to a chassis 3 fitted with a series of wheels 4 oriented in a longitudinal alignment. Chassis 3 comprises lateral flanges 30, 31 interconnected by bridges 32, 33 located respectively at the front and at the rear of the shoe. Bridges have portions extending laterally beyond the side flanges on either side of these, so as to provide sufficient bearing surfaces with the sole 20 of the shoe with which they come together. The assembly of the chassis on the shoe can be use any suitable fixing means such as screws, rivets, gluing, welding, interlocking or any combination appropriate of these means.

    La partie de chaussure comprend une base de coque 5, en plastique dur par exemple, qui forme une partie rigide de la chaussure recouvrant au moins partiellement le pied. La région recouverte par la base de coque 5 peut être variable selon le type d'utilisation de la chaussure. Dans le contexte d'un patin du type « aggressive », la base de coque est en général assez étendue pour des raisons de protection et de maintien du pied. Elle s'étend de manière sensiblement continue de la région des orteils 50 jusqu'au contrefort de talon arrière 51. La base de coque peut remonter plus ou moins haut par rapport à la région des malléoles selon les cas. Une ouverture 52 est généralement prévue sur le dessus du pied sur les bords de laquelle des moyens de serrage du type passants 53 ou autres, sont prévus pour ajuster en serrage le volume de la base de coque. Par endroit, une partie de la base de coque pourrait être formée d'un matériau souple tel qu'un textile ou autre, bien entendu sans pour cela sortir du cadre de l'invention.The shoe part comprises a shell base 5, in hard plastic for example which forms a rigid part of the shoe at least partially covering the foot. The region covered by the shell base 5 can be variable depending on the type of shoe use. In the context of a skate of the "aggressive" type, the hull base is generally quite extended for reasons of protection and support of the foot. It extends substantially continuously from the region of toes 50 to the rear heel counter 51. The base of shell can go up more or less high compared to the region malleoli as appropriate. An opening 52 is generally provided on the top of the foot on the edges of which clamping means of the passers-by type 53 or other, are provided to tighten the volume of the shell base. Through place, part of the shell base could be formed of a flexible material such as a textile or the like, of course without departing from the scope of the invention.

    La base de coque est prolongée vers le haut en direction de la jambe par un collier 6, lui aussi comprenant, au moins, des portions relativement rigides destinées à assurer des prises d'appui et une protection du bas de jambe. Il peut s'agir d'une pièce plastique relativement rigide ayant une forme générale tubulaire ouverte vers l'avant comprenant un recouvrement ajustable au serrage par au moins un moyen de serrage 7 du type à boucle, par exemple. Le collier possède une région de support arrière 60 offrant une partie d'appui large et confortable à la base du mollet lors des appuis arrières.The hull base is extended upwards towards the leg by a collar 6, also comprising, at least, relatively rigid portions intended to ensure grips support and lower leg protection. It can be a relatively rigid plastic part having a general shape tubular open towards the front including a cover adjustable to clamping by at least one clamping means 7 of the type loop, for example. The collar has a support region rear 60 offering a wide and comfortable support part to the base of calf during rear support.

    Le collier 6 se rapporte sur la base de coque par recouvrement partiel d'une portion basse du collier sur une portion haute de la base de coque approximativement dans la région des malléoles. L'ancrage principal du collier sur la base de coque est réalisé par des moyens de liaison 8 situés de chaque côté de la chaussure. La chaussure possède aussi des autres éléments tels qu'un chausson rembourré souple interne 40, par exemple, essentiel pour le confort du pied. La figure 1 montre l'un des moyens de liaison du côté extérieur. Il faut réaliser qu'un autre moyen de liaison se situe à l'opposé du côté intérieur. Ainsi, le collier est assemblé selon deux moyens de liaison latéraux favorisant une flexibilité avant/arrière du bas de jambe.The collar 6 relates to the shell base by partial covering of a lower portion of the collar on a upper portion of the shell base approximately in the malleoli region. The main anchoring of the collar on the hull base is produced by connecting means 8 located each side of the shoe. The shoe also has other elements such as an internal soft padded liner 40, for example, essential for the comfort of the foot. Figure 1 shows one of the connecting means on the outside. It is necessary realize that another connection means is located opposite the interior side. Thus, the necklace is assembled in two lateral connection means favoring flexibility front / back of the lower leg.

    Sur la chaussure représentée, la flexibilité avant/arrière est contrôlée vers l'avant et vers l'arrière par un moyen de rappel élastique 9 consistant en un arceau arrière 61 du collier et une ouverture arrière 62 séparant l'arceau de la partie d'appui arrière 60 du collier. La base de l'arceau 610 est apte à se déformer élastiquement pour favoriser un mouvement sensiblement de rotation du collier dans une direction avant/arrière. Un moyen de butée arrière 10 est prévu afin d'arrêter le déplacement du collier, plus spécifiquement de l'arceau 61, par rapport à la base de coque. Pour cela, l'arceau 61 présente un bord inférieur 611 en appui sur un bord supérieur 510 du contrefort talon. Afin de jouer son rôle de moyen de rappel élastique du collier, l'arceau 61 est fixé à la base de coque au moyen d'élément de fixation 11 approprié. Dans une configuration démontable du collier, il sera prévu des moyens du type à vis, de préférence, des vis auto-taraudables engagées directement dans la matière de la base de coque ou dans des éléments indépendants. Dans une alternative, les moyens de fixation 11 peuvent être omis de façon à libérer la flexion de l'arrière vers l'avant, favorisant ainsi le mouvement de patinage. Dans ce cas, l'arceau joue le rôle de moyen de rappel élastique par déformation lors d'un appui arrière vers un retour à la position de repos.On the shoe shown, the front / rear flexibility is controlled forwards and backwards by means of elastic return 9 consisting of a rear hoop 61 of the collar and a rear opening 62 separating the arch from the rear support part 60 of the collar. The base of the roll bar 610 is able to deform elastically to favor a substantially rotational movement of the collar in a forward / backward direction. A rear stop means 10 is provided in order to stop the movement of the collar, more specifically of the arch 61, relative to the hull base. For it, the arch 61 has a lower edge 611 bearing on an edge upper 510 of the heel counter. In order to play its role of elastic return means of the collar, the arch 61 is fixed to the shell base by means of appropriate fastening element 11. In a removable configuration of the collar, provision will be made for screw type means, preferably self-tapping screws engaged directly in the material of the hull base or in independent elements. In an alternative, the fastening means 11 can be omitted so as to release the bending from back to front, thus promoting skating movement. In this case, the roll bar plays the role of elastic return means by deformation when pressed back to a return to the rest position.

    Les moyens de liaison 8 vont maintenant être décrits de façon plus détaillée sur la base de la construction prédéfinie étant entendu que cette base de construction n'est pas la seule possible et que les moyens de liaison peuvent être adaptés à d'autres types de constructions du type « base de coque/collier » ou autres. The connection means 8 will now be described from in more detail based on the predefined construction it being understood that this building base is not the only one possible and that the connecting means can be adapted to other types of constructions such as "base of shell / collar "or others.

    La figure 2 montre le détail d'un moyen de liaison 8 du collier 6 sur la base de coque 5. La base de coque est munie d'un trou 54 circulaire d'axe I s'étendant transversalement. Le collier est, quant à lui, muni d'une lumière oblongue 63, de préférence orientée sensiblement verticalement. Le moyen de liaison 8, proprement dit, comprend un élément de vis 80 et un élément d'écrou 81 complémentaire qui assure l'assemblage du collier sur la base de coque au travers du trou 54 et de la lumière oblongue 63. On comprend que la lumière 63 favorise un déplacement relatif du collier par rapport à la base de coque selon la direction principale d'orientation I1 de la lumière. Dans cette configuration, on comprend que la liaison favorise un déplacement avant/arrière mais aussi transversal ou latéral du collier par rapport à la base de coque. Dans un mouvement avant/arrière, la lumière crée un déplacement de l'axe virtuel d'articulation qui est localisé alors vers l'arrière du collier, plus spécifiquement au voisinage de la base 610 de l'arceau. Le moyen de liaison 8 est donc un moyen de liaison partiel dans le sens où il doit maintenir la jonction des pièces rigides 5, 6 entre elles tout en autorisant un degré de liberté dans une ou plusieurs directions privilégiées déterminées; le déplacement relatif fonctionnant par glissement des surfaces de contact des pièces 5, 6 entre elles.Figure 2 shows the detail of a connecting means 8 of the collar 6 on the shell base 5. The shell base is provided with a circular hole 54 of axis I extending transversely. The collar is, in turn, provided with an oblong lumen 63, preferably oriented substantially vertically. The connecting means 8, proper, comprises a screw element 80 and a complementary nut element 81 which assembles the collar on the shell base through the hole 54 and the oblong opening 63. It is understood that the light 63 promotes a relative movement of the collar relative to the shell base in the main direction of orientation I 1 of the light. In this configuration, it is understood that the connection promotes forward / backward movement but also transverse or lateral movement of the collar relative to the shell base. In a forward / backward movement, the light creates a displacement of the virtual axis of articulation which is then located towards the rear of the collar, more specifically in the vicinity of the base 610 of the arch. The connecting means 8 is therefore a partial connecting means in the sense that it must maintain the junction of the rigid parts 5, 6 with one another while allowing a degree of freedom in one or more given preferred directions; the relative displacement operating by sliding of the contact surfaces of the parts 5, 6 between them.

    Bien entendu, on peut aussi prévoir que la lumière soit ménagée sur la base de coque alors que le trou 54 est ménagé dans le collier. On peut aussi bien faire varier l'orientation de la lumière selon la cinétique de mouvement recherchée.Of course, we can also provide that the light is formed on the shell base while the hole 54 is formed in the necklace. We can also vary the orientation light according to the kinetics of movement sought.

    Comme le montre la figure 4 en détail, l'élément de vis 80 comprend une tête 800 se prolongeant par une partie de tige 801 comprenant une portion filetée 802. La tête 800 prend appui sur les bords de la surface externe 630 du collier. La tête 800 est munie d'une empreinte de clé, du type alène, par exemple. L'élément d'écrou 81 comprend, quant à lui une tête 810 en appui sur les bords de la surface interne 540 de la base de coque. Il est muni aussi d'une portion tubulaire 811 comprenant une surface interne filetée 812 et une surface externe 815 de diamètre correspondant sensiblement au diamètre du trou 54 dans lequel elle s'engage. La surface annulaire externe 815 est le moyen de guidage de l'axe formé par le moyen de liaison à la fois dans le trou 54 et dans la lumière oblongue 63. La partie de tige filetée 801 coopère au vissage avec la portion tubulaire filetée 811 de façon à rapprocher la base de coque du collier tout en laissant un jeu fonctionnel qui autorise un mouvement de glissement relatif des pièces de la chaussure entre elles; en particulier, dans le cas présent, selon la direction définie par l'oblong.As shown in Figure 4 in detail, the screw member 80 includes a head 800 extending by a rod portion 801 comprising a threaded portion 802. The head 800 is supported on the edges of the outer surface 630 of the collar. Head 800 is provided with a key imprint, of the awl type, for example. The nut element 81 comprises, for its part, a head 810 in press on the edges of the internal surface 540 of the base of shell. It is also provided with a tubular portion 811 comprising an internal threaded surface 812 and an external surface 815 of diameter corresponding substantially to the diameter of hole 54 in which it undertakes. The external annular surface 815 is the means for guiding the axis formed by the means for connecting to the times in hole 54 and in oblong lumen 63. The part of threaded rod 801 cooperates in screwing with the portion 811 threaded tubular so as to bring the shell base closer to the collar while leaving a functional play which allows a relative sliding movement of the shoe parts between them; in particular, in this case, according to the direction defined by oblong.

    Selon une caractéristique essentielle de l'invention, la partie de tige 801 comprend une portion d'extrémité 803 opposée à la tête 800 de l'élément de vis. Cette extrémité est formée par une portion de lèvre 804 bouterollée qui déborde radialement au delà de la section de la surface interne filetée 812 afin de sécuriser l'élément de vis selon la direction de l'axe d'engagement I du moyen de liaison. Pour cela, l'élément d'écrou possède un puits 813 débouchant vers l'extérieur dont la section est, de préférence, celle d'une empreinte de clé, par exemple de type alène. Vers l'intérieur, le puits se raccorde à la surface interne filetée 812 par un bord d'épaulement annulaire 814 contre lequel la portion de lèvre prend appui.According to an essential characteristic of the invention, the stem portion 801 includes an opposite end portion 803 at the head 800 of the screw element. This end is formed with a portion of lip 804 which is protruding overflowing radially beyond the section of the internal threaded surface 812 to secure the screw element in the direction of the axis of engagement I of the connecting means. For this, the element nut has a well 813 opening to the outside, the section is preferably that of a key fingerprint, for example of the awl type. Inward, the well is connects to the internal threaded surface 812 by an edge 814 annular shoulder against which the lip portion is supported.

    La figure 3 illustre la méthode d'assemblage du collier 6 sur la base de coque 5. Dans un premier temps, l'élément d'écrou 81 est préengagé au travers du trou 54. L'élément de vis 80 est alors rapporté et vissé avec l'élément d'écrou 81 jusqu'à atteindre un niveau de serrage approprié qui assure a la fois une résistance mécanique suffisante fonction de la longueur de filetage tout en laissant un jeu suffisant entre les pièces 5, 6 afin d'autoriser leur déplacement relatif par glissement. Dans un second temps, on effectue le bouterollage de l'extrémité 803. Pour cela, on utilise un outil de bouterollage adapté à cette opération comprenant un poinçon 90 muni d'une empreinte 91 de forme annulaire concave. L'empreinte doit avoir une section inférieure à la section du puits 813 de l'élément d'écrou afin d'atteindre l'extrémité à bouteroller. Au départ l'extrémité de l'élément de vis comprend une portion tubulaire rectiligne. Cette portion est déformée par action du poinçon de façon à former une portion de lèvre continue annulaire qui déborde radialement et prend appui sur le bord 814 du puits de l'élément d'écrou. L'outil possède à l'opposé une surface d'appui 92 pour l'appui de la tête de l'élément de vis 80 lors de l'opération.Figure 3 illustrates the method of assembling the collar 6 on the hull base 5. First, the element nut 81 is pre-engaged through hole 54. The element of screw 80 is then attached and screwed with the nut element 81 until an appropriate tightening level is reached which ensures both sufficient mechanical strength depending on the thread length while leaving sufficient clearance between parts 5, 6 in order to authorize their relative displacement by slip. In a second step, we do the rolling end 803. For this, we use a bolting adapted to this operation including a punch 90 provided with a concave annular imprint 91. The imprint must have a section smaller than the section of well 813 of the nut element in order to reach the end to be bolted. At the start, the end of the screw element includes a portion straight tubular. This portion is deformed by the action of punch so as to form a portion of continuous lip annular which projects radially and bears on the edge 814 from the nut element well. The tool has the opposite a bearing surface 92 for supporting the head of the element of screw 80 during the operation.

    La figure 5 montre l'opération de démontage du moyen de liaison par deux clés 93, 94 engageant les empreintes 805, 813 formées dans les têtes des éléments 80, 81. Au delà d'un certain seuil prédéterminé de couple de desserrage, il est possible de supprimer le bouterollage soit par déformation élastique de la portion de lèvre, soit par rupture de la portion de lèvre sous l'effort de couple appliqué. Toutefois, le démontage peut être destructif dans le sens où l'élément 80 peut être endommagé dans certain cas de rupture de la lèvre. Dans ce cas, l'élément de vis est remplacé par un nouvel élément et le montage est effectué selon la méthode décrite précédemment. Contrairement à un assemblage à rivet, le démontage est une opération facilitée qui n'emploie que des clés traditionnelles et en appliquant un couple suffisant de desserrage.Figure 5 shows the disassembly operation of the means of connection by two keys 93, 94 engaging the fingerprints 805, 813 formed in the heads of elements 80, 81. Beyond a certain predetermined loosening torque threshold, it is possible to remove the rolling or by deformation elasticity of the lip portion, either by rupture of the portion of lip under the applied torque force. However, disassembly can be destructive in the sense that element 80 may be damaged in some cases of lip rupture. In this case, the screw element is replaced by a new one. element and assembly is carried out according to the method described previously. Unlike a rivet connection, the disassembly is a facilitated operation which only employs traditional keys and applying a sufficient couple of loosening.
