Description

La présente invention concerne un dispositif de verrouillage d'aiguillage ferroviaire, notamment du type de ceux concernés par la norme NF F 52-162.The present invention relates to a rail switch locking device, in particular of the type of those concerned by the NF F 52-162 standard.

Ces dispositifs sont également connus sous la dénomination verrous « VCC » (pour Verrou Carter Coussinet). Il est nécessaire d'utiliser ces dispositifs par paire, puisqu'il faut un verrou par aiguille : les deux verrous sont commandés ensemble par un élément de liaison indéformable. Dans le cadre de l'invention, et par soucis de concision, on ne décrira qu'un verrou seul, bien que destiné à fonctionner par paire, et on utilisera indifféremment le terme « dispositif de verrouillage d'aiguillage ferroviaire » et le terme plus concis de « verrou ».These devices are also known under the name locks "VCC" (for Cargo Lock Bush). It is necessary to use these devices in pairs, since a needle lock is required: the two locks are controlled together by a dimensionally stable connecting element. In the context of the invention, and for the sake of brevity, only one lock will be described, although intended to operate in pairs, and the term "railway switch locking device" will be used interchangeably and the term concise "lock".

Le document WO 99/20513 décrit un dispositif de verrouillage d'aiguillage avec deux verroux en liaison.The document WO 99/20513 describes a switch locking device with two interlocks in connection.

Ces paires de verrous assurent la manoeuvre et le verrouillage de l'aiguille fermée contre sa contre-aiguille (c'est-à-dire la portion de rail correspondante), la manoeuvre et le calage de l'aiguille en position ouverte. La détection de la lame d'aiguille ouverte correctement écartée de sa contre-aiguille, la détection de la position de la lame correctement fermée contre sa contre-aiguille, et la détection du verrou de lame fermée en position de verrouillage sont assurées par un contrôleur de verrou.These pairs of locks ensure the operation and locking of the closed needle against its counter-needle (that is to say the corresponding rail portion), the maneuver and the setting of the needle in the open position. The detection of the open needle blade correctly spaced from its counter-needle, the detection of the position of the blade properly closed against its counter-needle, and the detection of the closed blade lock in the locking position are performed by a controller lock.

Chaque verrou comporte généralement un bâti protégé par un couvercle, un bras de verrouillage associé à une « main » (décrite plus loin). L'ensemble, usuellement appelé« C-main », fonctionne en accord avec un ensemble de verrouillage et un contrôleur de verrou, appelé également détecteur de verrou.Each lock generally comprises a frame protected by a cover, a locking arm associated with a "hand" (described below). The assembly, usually called "C-hand", works in accordance with a lock assembly and a lock controller, also called a lock detector.

On peut décomposer ce verrou en deux parties : une partie fixe liée au bâti, qu'on vient solidariser à la contre-aiguille et qui est destinée à être fixée à l'extérieur de la voie, et une partie mobile, qui est entraînée par un organe de commande commun aux deux verrous et qui est liée mécaniquement à l'aiguille, cette partie mobile assurant l'application de l'aiguille contre la contre-aiguille, son verrouillage sur la partie fixe, et le fonctionnement du contrôleur. Elle autorise aussi le déplacement longitudinal de l'aiguille par rapport à sa contre-aiguille sous l'effet de sollicitations diverses.This lock can be broken down into two parts: a fixed part linked to the frame, which is secured to the counter-needle and which is intended to be fixed outside the track, and a movable part, which is driven by a control member common to the two locks and which is mechanically linked to the needle, this moving part ensuring the application of the needle against the counter-needle, its locking on the fixed part, and the operation of the controller. It also allows longitudinal movement of the needle relative to its counter-needle under the effect of various stresses.

Ces verrous intègrent un boulon creux comprenant une vis équipée d'une tête dite « marteau », un écrou auto-chanfreiné ou sécurisé et au moins une rondelle s'interposant entre vis et écrou. La vis est percée axialement d'un orifice traversant, permettant le passage d'un piston, généralement en bronze, à l'intérieur dudit orifice libre en translation. Elle sera désignée ci-après sous le terme de vis creuse.These locks incorporate a hollow bolt comprising a screw equipped with a so-called "hammer" head, a self-chamfered or secured nut and at least one washer interposed between screw and nut. The screw is pierced axially with a through orifice, allowing the passage of a piston, usually made of bronze, inside said free orifice in translation. It will be referred to hereinafter as hollow screw.

Ce boulon à tête marteau assure plusieurs fonctions : il permet de positionner et fixer le bâti contre l'âme de la contre-aiguille, et il autorise la libre translation du piston mentionné plus haut qui doit prendre appui sur la lame d'aiguille pour manoeuvrer le contrôleur localisé de l'autre côté de la contre-aiguille.This hammerhead bolt performs several functions: it allows to position and fix the frame against the core of the counter-needle, and it allows the free movement of the piston mentioned above which must be supported on the needle blade to maneuver the controller located on the other side of the counter-needle.

Ce boulon creux se trouve soumis à différentes contraintes mécaniques, notamment aux efforts de serrage, et aux vibrations créés par les passages des véhicules ferroviaires sur les voies. Ces contraintes peuvent finir par provoquer la rupture de la vis, le plus souvent localisées dans la zone où la vis se raccorde à sa tête marteau, au niveau de laquelle se concentrent les contraintes mécaniques, du fait du grand changement de section entre le corps de la vis d'une part, et la tête marteau d'autre part.This hollow bolt is subject to various mechanical stresses, including clamping forces, and vibrations created by the passage of railway vehicles on the tracks. These stresses may eventually cause the screw to break, most often located in the area where the screw is connected to its hammer head, at the level of which the mechanical stresses are concentrated, because of the large sectional change between the body of the screw. the screw on the one hand, and the hammer head on the other.

L'invention a alors pour but de remédier au moins en partie à cet inconvénient. Elle a pour but d'améliorer la conception des boulons creux utilisés dans les verrous, notamment en vue de diminuer les risques de casse de ceux-ci.The object of the invention is therefore to remedy at least part of this disadvantage. Its purpose is to improve the design of hollow bolts used in locks, in particular to reduce the risk of breakage thereof.

L'invention a pour objet un dispositif de verrouillage d'aiguillage ferroviaire comprenant une partie fixe destinée à être solidarisée à un rail contre-aiguille et une partie mobile par rapport à ladite partie fixe et destinée à être fixée sur l'aiguille correspondante. La partie mobile permet l'application de l'aiguille sur le rail contre-aiguille et son verrouillage au moyen d'un bras de verrouillage destiné à être entraîné par un organe de manoeuvre de l'aiguillage. La partie fixe comprend un boulon à vis creuse dans laquelle coulisse un piston destiné à être actionné par l'aiguille afin de commander le contrôleur dudit dispositif de verrouillage. La vis creuse, selon l'invention, comporte un corps de vis et une tête marteau qui est distincte du corps de vis et qui est solidarisée à celui-ci.The subject of the invention is a railway switch locking device comprising a fixed part intended to be secured to a counter-needle rail and a part movable relative to said fixed part and intended to be fixed on the corresponding needle. The movable part allows the application of the needle on the counter-needle rail and its locking by means of a locking arm intended to be driven by an actuating member of the switch. The stationary portion includes a hollow screw bolt in which a piston to be actuated by the needle slides to control the controller of the locking device. The hollow screw according to the invention comprises a screw body and a hammer head which is distinct from the screw body and which is secured thereto.

Grâce à cette vis creuse en deux parties, il s'est avéré que les efforts mécaniques auxquels elle était soumise pouvaient être mieux répartis, notamment sur toute la longueur de la liaison mécanique prévue entre le corps de vis et sa tête, et non plus se concentrer majoritairement au niveau de la base de la tête de vis. On augmente ainsi significativement la tenue à l'effort de la vis, donc du boulon dans son ensemble.Thanks to this hollow screw in two parts, it turned out that the mechanical forces to which it was subjected could be better distributed, especially over the entire length of the mechanical connection provided between the screw body and its head, and no longer concentrate mainly at the base of the screw head. This significantly increases the resistance to effort of the screw, so the bolt as a whole.

De préférence, le corps de vis et sa tête marteau sont solidarisés par engagement d'une extrémité du corps de vis dans un orifice (traversant) pratiqué dans la tête marteau.Preferably, the screw body and its hammer head are secured by engaging one end of the screw body in a hole (through) formed in the hammer head.

Plus particulièrement, on peut prévoir que la solidarisation se fasse par emmanchement conique du corps de vis dans l'orifice pratiqué dans la tête marteau.More particularly, it can be provided that the fastening is done by conical fitting of the screw body in the hole made in the hammer head.

Ainsi, les contraintes mécaniques sont réparties sur toute la longueur de l'interface, par exemple conique dans le cas d'un emmanchement conique, entre les deux pièces, longueur que l'on peut adapter en fonction des besoins et du dimensionnement des pièces.Thus, the mechanical stresses are distributed over the entire length of the interface, for example conical in the case of a conical fitting, between the two parts, which length can be adapted according to the needs and dimensioning of the parts.

Optionnellement, le corps de vis et sa tête marteau sont munis de moyens de positionnement relatif, notamment des moyens de centrage radial par rapport à l'axe du corps de vis.Optionally, the screw body and its hammer head are provided with relative positioning means, in particular radial centering means with respect to the axis of the screw body.

Il peut notamment s'agir d'un pion sur l'une des pièces coopérant avec une échancrure de forme complémentaire sur l'autre pièce, par exemple d'un pion saillant radialement à l'extrémité du corps de vis et coopèrant avec une échancrure de forme complémentaire dans l'orifice de la tête marteau dans lequel est engagée ladite extrémité du corps de vis.It may in particular be a pin on one of the parts cooperating with a notch of complementary shape on the other part, for example a pin protruding radially at the end of the screw body and cooperating with a notch of complementary shape in the hole of the hammer head in which is engaged said end of the screw body.

Ces moyens de positionnement relatif facilitent le montage du boulon : ils viennent aider l'opérateur à orienter correctement la tête marteau par rapport à l'axe de la vis creuse avant le serrage avec l'écrou (La tête marteau n'a en effet pas une forme de révolution par rapport à l'axe de la vis), ce qui présente tout particulièrement un intérêt quand vis et tête marteau sont assemblées sur site. Quand on prévoit plutôt d'assembler les pièces en usine, on peut ne pas y avoir recours ou réaliser le détrompage différemment.These relative positioning means facilitate the mounting of the bolt: they come to help the operator to correctly orient the hammer head relative to the axis of the hollow screw before tightening with the nut (The hammer head has indeed not a form of revolution relative to the axis of the screw), which is particularly relevant when screws and hammer head are assembled on site. When we plan to assemble the parts in the factory, we may not use them or perform the foolproofing differently.

On peut prévoir de munir la vis creuse, notamment le corps de vis, de moyens anti-rotation de l'écrou associé : Ils permettent d'empêcher la rotation de la vis quand on vient serrer la vis sur le bâti avec l'écrou.It may be provided to provide the hollow screw, including the screw body, anti-rotation means of the associated nut: They prevent the rotation of the screw when it comes to tighten the screw on the frame with the nut.

Ces moyens anti-rotation peuvent prendre la forme d'au moins une zone saillante ou en creux sur la face d'extrémité du corps de vis opposée à l'extrémité engagée dans la tête marteau, apte à former une prise pour / s'engager dans un outil présentant la forme complémentaire de cette zone saillante ou en creux.These anti-rotation means may take the form of at least one protruding zone or hollow on the end face of the screw body opposite to the end engaged in the hammer head, able to form a catch for / engage in a tool having the complementary shape of this projecting area or hollow.

L'écrou associé à la vis creuse est de préférence un écrou auto-freiné.The nut associated with the hollow screw is preferably a self-locking nut.

D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lumière de la description qui va suivre et des dessins annexés, concernant un mode de réalisation particulier, non limitatif, en référence aux figures suivantes:

Ces figures sont très schématiques et ne respectent pas nécessairement l'échelle entre les différents éléments représentés afin d'en faciliter la lecture. Les mêmes éléments portent les mêmes références dans l'ensemble des figures. Tous les composants du verrou ne sont pas nécessairement représentés ou décrits en détails, seuls ceux important à l'invention le sont. Il est à noter que toutes les indications de disposition dans l'espace, de type « haut », « bas », « supérieur », « inférieur », « latéral » se comprennent en considérant le verrou en position de fonctionnement sur une voie ferrée.These figures are very schematic and do not necessarily respect the scale between the different elements represented in order to facilitate reading. The same elements bear the same references in all the figures. All components of the lock are not necessarily represented or described in detail, only those important to the invention are. It should be noted that all the indications of spatial arrangement, of the "up", "down", "upper", "lower", "lateral" type are understood by considering the lock in operating position on a railway .

Les figures 1 à 4 décrivent donc le verrou V dans son ensemble, tandis que les figures 5 et 6 se concentrent sur les composants visés plus particulièrement par l'invention. Le principe de fonctionnement d'un verrou muni de son contrôleur est connu en soi et ne sera pas décrit en détails.The Figures 1 to 4 therefore describe the V latch as a whole, while the Figures 5 and 6 concentrate on the components targeted more particularly by the invention. The operating principle of a lock with its controller is known per se and will not be described in detail.

La figure 1 représente la partie fixe PF du verrou V, celle fixée, en fonctionnement, au bord extérieur du rail contre-aiguille. Elle comporte un bâti 1 en métal, usiné pour s'adapter à la forme de la contre-aiguille, de l'aiguille et de la forme de la voie ferroviaire. Ce bâti 1 présente un corridor de translation et une chambre de verrouillage, elle-même usinée pour satisfaire les conditions d'ouverture de l'aiguillage, de façon connue.The figure 1 represents the fixed part PF of the lock V, that fixed, in operation, to the outer edge of the counter-needle rail. It comprises a metal frame 1, machined to adapt to the shape of the counter-needle, the needle and the shape of the railway track. This frame 1 has a translation corridor and a locking chamber, itself machined to meet the opening conditions of the switch, in known manner.

La partie fixe PF du verrou comporte aussi une plaque de base 2, en métal également, fixée au bâti 1 par des vis 3, et un support 4 vis-à-vis d'une fourrure de glissement 5 sur laquelle la lame d'aiguille se déplace. Le support 4 de la fourrure 5 est inséré dans le bâti 1 et fixé sur la plaque de base 2 par un pion de centrage et une vis 6. La partie fixe comprend aussi un boulon creux 7 comprenant une vis creuse 71 qui traverse une paroi du bâti et qui est équipée d'une tête marteau 72, d'une rondelle élastique 73 et d'un écrou auto-freiné 74, dans lequel coulisse un piston 75 (représenté à la figure 4) en bronze qui commande le contrôleur 30. Elle comprend aussi une pièce de verrouillage en bronze 8 fixée au bâti 1 par une vis 9. Elle prévoit aussi deux demi-colliers 10 pour la fixation des câbles des contrôleurs, et deux mâchoires 11 et leurs fixations 12 plaquant le bâti 1 contre le pied de la contre-aiguille. Elle prévoit aussi un capot de protection 13 et une trappe d'accès 14 facilitant l'accès pour diverses opérations de maintenance.The fixed portion PF of the lock also comprises a base plate 2, also of metal, fixed to the frame 1 by screws 3, and a support 4 vis-à-vis a sliding fur 5 on which the needle blade moves. The support 4 of the fur 5 is inserted in the frame 1 and fixed on the base plate 2 by a centering pin and a screw 6. The fixed part also comprises a hollow bolt 7 comprising a hollow screw 71 which passes through a wall of the frame and which is equipped with a hammer head 72, an elastic washer 73 and a self-locking nut 74, in which slides a piston 75 (shown in FIG. figure 4 ) It also comprises a bronze locking piece 8 fixed to the frame 1 by a screw 9. It also provides two half-collars 10 for fixing the cables of the controllers, and two jaws 11 and their fasteners 12 pressing the frame 1 against the foot of the counter-needle. It also provides a protective cover 13 and an access hatch 14 facilitating access for various maintenance operations.

La figure 2 représente la partie mobile PM du verrou, celle fixée à l'aiguille. Elle comprend un bras de verrouillage 15 (« C») en métal muni d'une branche de commande 16. Le bras de verrouillage est guidé le long de la fourrure de glissement 5 de la figure 1 par la glissière inférieure 15A et repose sur la plaque de base par l'intermédiaire d'un patin de glissement 17. Un trou 18 à l'extrémité de la branche de commande 16 permet la fixation de la tringle de connexion permettant une commande commune aux deux verrous d'un système d'aiguillage complet, par l'intermédiaire d'un axe non représenté. La « main » de fixation 19 est fixée contre l'âme de la lame d'aiguille par l'intermédiaire de deux trous oblongs 20, de façon à autoriser un déplacement longitudinal de la lame d'aiguille, dû notamment à des phénomènes de dilatation. L'ensemble de verrouillage « C-main » est fixé à la lame d'aiguille par des boulons à tête marteau 21 équipés de rondelles et d'un écrou auto-freiné, l'ensemble étant sécurisé par une goupille fendue 22. La tête de verrouillage de l'ensemble « C-main » est équipée d'un patin de glissement de tête 23 tenu mécaniquement par une vis 24 et d'une encoche 25 servant au guidage du bras de commande du contrôleur. Le bras de verrouillage « C » et la main de fixation sont maintenus solidaires par un axe et unebague, ce qui autorise un mouvement de rotation du « C » par rapport à la « main ».The figure 2 represents the movable part PM of the lock, that fixed to the needle. It comprises a locking arm 15 ("C") of metal provided with a control arm 16. The locking arm is guided along the sliding fur 5 of the figure 1 by the lower slide 15A and rests on the base plate via a sliding pad 17. A hole 18 at the end of the control branch 16 allows the attachment of the connecting rod for common control to the two locks of a complete referral system, through a axis not shown. The "hand" fastening 19 is fixed against the core of the needle blade by means of two oblong holes 20, so as to allow a longitudinal displacement of the needle blade, due in particular to expansion phenomena . The lock assembly "C-hand" is attached to the needle blade by hammerhead bolts 21 equipped with washers and a self-locking nut, the assembly being secured by a cotter pin 22. The head The locking system of the "C-main" assembly is equipped with a head sliding shoe 23 held mechanically by a screw 24 and a notch 25 serving to guide the control arm of the controller. The locking arm "C" and the fixing hand are held together by an axis and a ring, which allows a rotation movement of the "C" relative to the "hand".

La figure 3 est une vue de dessus de l'ensemble du verrou V associant les parties fixe PF et mobile PM des figures 1 et 2, en position ouverte, la partie fixe étant solidarisée à un rail contre-aiguille 26 et la partie mobile étant solidarisée à l'aiguille 27. En position fermée, l'aiguille est plaquée contre sa contre-aiguille par un mouvement relatif entre partie fixe et partie mobile du verrou, puis bloquée en position.The figure 3 is a top view of the assembly of the lock V associating the fixed parts PF and mobile PM of Figures 1 and 2 in the open position, the fixed part being secured to a counter-needle rail 26 and the movable part being secured to the needle 27. In the closed position, the needle is pressed against its counter-needle by a relative movement between the fixed part and mobile part of the lock, and then locked in position.

La figure 4 est une vue latérale du verrou V, qui montre l'écrou 74 du boulon creux 7, son piston 75 et le contrôleur de verrou 30 associé au verrou V, le verrou étant en position fermée-verrouillée.The figure 4 is a side view of the lock V, which shows the nut 74 of the hollow bolt 7, its piston 75 and the lock controller 30 associated with the lock V, the latch being in the closed-locked position.

Les figures 5 et 6 représentent, de façon isolée, la vis creuse 71 associée à sa tête marteau 72. La vis creuse 71 est percée d'un orifice cylindrique O traversant en son centre, sur toute sa longueur le long de son axe longitudinal X, de façon à permettre le coulissement libre du piston 75.The Figures 5 and 6 represent, in an isolated manner, the hollow screw 71 associated with its hammer head 72. The hollow screw 71 is pierced with a cylindrical orifice O crossing at its center, along its entire length along its longitudinal axis X, so as to allow the free sliding of the piston 75.

Selon les solutions techniques antérieures, cette vis creuse était d'un seul tenant avec sa tête.According to the prior technical solutions, this hollow screw was in one piece with its head.

Ici, et selon l'invention, la vis se décompose en un corps de vis 71 (désigné aussi indifféremment sous le terme de tige creuse filetée dans le présent texte), qui est fileté sur une partie de sa longueur au moins L2, qui est assemblée à une tête marteau 72, qui est une pièce distincte. Les deux pièces sont liées mécaniquement par emmanchement conique de l'une des extrémités de la tige filetée 71 dans un orifice traversant dans la tête marteau 72. Ce type de montage est connu en soi : la tige est insérée en force dans l'orifice, dans une zone où les deux composants présentent une forme conique complémentaire, de façon à assurer un coincement de la tige 71 dans l'orifice de la tête marteau 72. La liaison mécanique ainsi réalisée est solide (bien qu'il reste éventuellement possible de les désolidariser ultérieurement, le cas échéant). Cette interface de liaison sur une longueur L1 de la tige filetée 71 permet de répartir les efforts, au lieu, comme dans les solutions antérieures, de les concentrer à la base de la tête marteau 72. La réduction des contraintes au niveau de la base de la tête marteau 72 est considérable. Il a été mesuré que les contraintes internes maximales à l'intérieur du boulon 7 étaient réduites d'au moins 50%, et même atteignaient une réduction de 70%, en utilisant une vis en deux parties, ce qui conduit à diminuer drastiquement le nombre de casses, donc à limiter/espacer les interventions d'opérateur sur cette partie du verrou.Here, and according to the invention, the screw is broken down into a screw body 71 (also referred to alternatively as threaded hollow rod in the present text), which is threaded over a portion of its length at least L2, which is assembled to a hammer head 72, which is a separate piece. The two parts are mechanically linked by conical fitting of one of the ends of the threaded rod 71 in a through hole in the hammer head 72. This type of assembly is known per se: the rod is inserted into the orifice forcefully, in an area where the two components have a complementary conical shape, so as to ensure a jamming of the rod 71 in the hole of the hammer head 72. The mechanical connection thus made is solid (although it may still be possible to disconnect later, if necessary). This connection interface over a length L1 of the threaded rod 71 distributes the forces, instead, as in the Prior solutions, concentrate them at the base of the hammer head 72. The reduction of stresses at the base of the hammer head 72 is considerable. It was measured that the maximum internal stresses inside the bolt 7 were reduced by at least 50%, and even reached a 70% reduction, using a two-part screw, which leads to drastically reducing the number breaks, so to limit / space operator interventions on this part of the lock.

La figure 5, plus particulièrement, représente également un creux 77 délimitant un espace sensiblement cubique/parallélépipédique sur la tige filetée 71, sur sa face d'extrémité opposée à celle assemblée à la tête marteau 72. Ce creux 77 est un moyen anti-rotation de la tige filetée 71 : L'opérateur vient la serrer à l'aide de l'écrou 74 sur le bâti en engageant un outil présentant une tête de forme complémentaire dans ce creux, empêchant ainsi la tige de tourner en même temps que l'écrou lors du serrage. On peut bien sûr prévoir des formes différentes pour ce creux 78, tant qu'on choisit un volume qui n'est pas de révolution par rapport à l'axe X de la tige filetée 71. On peut aussi inverser la complémentarité des formes entre vis et outil, en prévoyant un pion ou autre élément saillant sur la face d'extrémité de la tige filetée 71, destinée à coopérer avec une tête de l'outil présentant alors un creux de forme complémentaire.The figure 5 , more particularly, also represents a hollow 77 delimiting a substantially cubic / parallelepipedal space on the threaded rod 71, on its end face opposite to that assembled to the hammer head 72. This hollow 77 is an anti-rotation means of the rod threaded 71: The operator comes to tighten it with the nut 74 on the frame by engaging a tool having a complementary shaped head in this hollow, thus preventing the rod from rotating together with the nut during the Tightening. We can of course provide different shapes for this hollow 78, as long as we choose a volume that is not revolution with respect to the X axis of the threaded rod 71. It is also possible to reverse the complementarity of the shapes between the screws. and tool, by providing a pin or other element projecting on the end face of the threaded rod 71, intended to cooperate with a head of the tool then having a complementary shaped depression.

La figure 6, plus particulièrement, représente également des moyens de centrage relatifs entre la tige filetée 71 et la tête marteau 72, sous la forme d'un pion saillant radialement 76 à l'extrémité de la tige filetée solidarisée à la tête 72, coopérant avec une échancrure de forme complémentaire présente au niveau de l'orifice conique de la tête 72 accueillant la tige filetée 71. Ainsi, avant le serrage avec l'écrou, l'opérateur peut facilement repérer comment positionner en orientation radiale par rapport à l'axe X les deux pièces entre elles. En effet, comme représenté aux figures, la tête marteau 72 présente une forme spécifique qui n'est pas de révolution par rapport à l'axe X, et il est important qu'elle soit positionnée correctement. Bien sûr, on peut choisir d'autres moyens de centrage/détrompage pour positionner les deux pièces l'une par rapport à l'autre, par exemple en inversant le positionnement de la partie mâle (pion, forme saillante) et de la partie femelle (creux) desdits moyens.The figure 6 more particularly, also represents relative centering means between the threaded rod 71 and the hammer head 72, in the form of a radially projecting pin 76 at the end of the threaded rod secured to the head 72, cooperating with a notch of complementary shape present at the conical orifice of the head 72 accommodating the threaded rod 71. Thus, before tightening with the nut, the operator can easily identify how to position in radial orientation with respect to the X axis the two rooms between them. Indeed, as shown in the figures, the hammer head 72 has a specific shape that is not revolution with respect to the X axis, and it is important that it is positioned correctly. Of course, one can choose other means of centering / foolproof to position the two parts relative to each other, for example by inverting the positioning of the male part (pin, protruding form) and the female part (hollow) of said means.

D'autres modes de réalisation de l'invention sont possibles. Ainsi, on peut envisager d'autres liaisons mécaniques pour solidariser la tige filetée 71 et sa tête marteau 72, tant qu'elles permettent un contact entre les deux pièces sur une longueur suffisante pour répartir les efforts.Other embodiments of the invention are possible. Thus, one can consider other mechanical connections to secure the threaded rod 71 and its hammer head 72, as long as they allow contact between the two parts over a sufficient length to distribute the forces.

Le procédé de serrage du boulon selon l'invention reste le même qu'avec la vis en un seul tenant des solutions antérieures. Il est simplement précédé de l'assemblage du corps de vis à la tête marteau, soit préalablement, soit lors de l'installation du verrou.The clamping method of the bolt according to the invention remains the same as with the screw in one piece previous solutions. It is simply preceded by the assembly of the screw body to the hammer head, either before or during the installation of the lock.
