Description

La présente invention concerne une clé utilisable par exemple pour l'actionnement des serrures de véhicules automobiles.The present invention relates to a key used for example for actuating locks of motor vehicles.

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Il existe des clés ayant une extrémité solidaire d'une chape montée entre deux joues d'un boîtier pour tourner autour d'un axe de pivotement entre une position escamotée de la clé dans le boîtier et une position sortie de la clé. Un poussoir de commande est monté dans la chape pour être solidaire en pivotement de celle-ci et pour coulisser entre une position sortie de blocage de la chape dans laquelle le poussoir a des ergots reçus dans des encoches du boîtier qui sont positionnées pour correspondre à chacune de ses positions, et une position enfoncée de libération du pivotement de la chape dans laquelle les ergots sont dégagés des encoches. Un ressort est intercalé entre le boîtier et le poussoir de commande pour rappeler élastiquement la chape dans sa position sortie et le poussoir de commande dans sa position de blocage.There are keys having an end secured to a clevis mounted between two cheeks of a housing for rotation about a pivot axis between a retracted position of the key in the housing and an extended position of the key. A control pusher is mounted in the yoke to be integral in pivoting thereof and to slide between an unlocked position of the yoke in which the pusher has lugs received in notches of the housing which are positioned to correspond to each its positions, and a recessed position of release of the pivoting of the yoke in which the lugs are clear of the notches. A spring is interposed between the housing and the control pusher for elastically returning the yoke in its extended position and the control pusher in its locking position.

Une telle clé est par exemple connue du document EP1 526 232 A1 , qui décrit une clé selon le préambule de la revendication 1.Such a key is for example known from the document EP1 526 232 A1 which describes a key according to the preamble of claim 1.

Le boîtier est généralement fabriqué en matière plastique tandis que le poussoir est lui réalisé en métal. Il est fréquent que le boîtier comporte à l'opposé de la chape un orifice de passage d'un anneau de porte-clé.The case is generally made of plastic while the pusher is made of metal. It is common for the housing to have opposite the clevis a passage opening of a key ring ring.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

On s'est aperçu que le maintien en position de la clé risquait de perdre de son efficacité au cours du temps en raison des efforts de pivotement exercés sur la clé ou le boîtier lorsque la clé est bloquée en position sortie. Ainsi, lorsque la clé en position sortie est engagée dans une serrure et que l'anneau de porte-clé est lourdement chargé, les ergots du poussoir exercent des contraintes importantes contre les parois des encoches qui ont tendance à se mater entraînant un évasement des encoches qui favorise l'échappement des ergots.It has been found that maintaining the position of the key could lose its effectiveness over time due to the pivoting forces exerted on the key or the housing when the key is locked in the extended position. Thus, when the key in the extended position is engaged in a lock and the key ring is heavily loaded, the lugs of the pusher exert significant stresses against the walls of the notches that tend to mater causing a flaring of the notches which promotes the escape of the lugs.

Pour remédier à ce problème, il aurait pu être envisagé d'augmenter la taille des surfaces en contact pour mieux répartir les contraintes. Il en aurait cependant résulté un accroissement de l'encombrement du boîtier. Une autre solution aurait été d'augmenter la raideur du ressort pour empêcher un échappement inopiné des ergots hors des encoches mais cela aurait rendu la manoeuvre du poussoir plus difficile.To remedy this problem, it could be envisaged to increase the size of the surfaces in contact to better distribute the constraints. However, this would have resulted in an increase in the size of the housing. Another solution would have been to increase the stiffness of the spring to prevent unexpected escape of the lugs out of the notches but it would have made the operation of the pusher more difficult.

Un but de l'invention est de fournir un moyen de blocage de la chape en position, qui soit plus fiable tout en restant simple.An object of the invention is to provide a means of locking the yoke in position, which is more reliable while remaining simple.

BREVE DESCRIPTION DE L'INVENTIONBRIEF DESCRIPTION OF THE INVENTION

A cet effet, on prévoit, selon l'invention, une clé ayant une extrémité solidaire d'une chape montée dans un boîtier pour tourner entre une position escamotée de la clé dans le boîtier et une position sortie de la clé, et un poussoir de commande monté dans la chape pour être solidaire en pivotement de celle-ci et pour coulisser entre une position sortie de blocage de la chape dans laquelle le poussoir possède au moins un ergot reçu dans une encoche d'une partie de boîtier et une position enfoncée de libération du pivotement de la chape dans laquelle l'ergot échappe à l'encoche, un ressort étant intercalé entre le boîtier et le poussoir de commande pour rappeler élastiquement la chape vers la position sortie et le poussoir de commande vers sa position de blocage, caractérisée en ce que l'encoche est ménagée dans une bague rapportée dans la partie de boîtier et en ce que la bague a une dureté supérieure au boîtier.For this purpose, according to the invention, there is provided a key having an end integral with a yoke mounted in a housing for rotation between a retracted position of the key in the housing and an extended position of the key, and a pusher of control mounted in the yoke to be integral in pivoting thereof and for sliding between an output position of locking the yoke in which the pusher has at least one lug received in a notch of a housing portion and a depressed position of release of the pivoting of the yoke in which the lug escapes the notch, a spring being interposed between the housing and the control pusher for resiliently returning the yoke to the extended position and the control pusher to its locking position, characterized in that the notch is formed in a ring attached in the housing part and in that the ring has a hardness greater than the housing.

Par bague, on entend toute pièce pourvue d'une ouverture lui permettant d'accueillir le poussoir. Ainsi, la bague est plus résistante mécaniquement que le boîtier et peut être réalisée dans un matériau aussi résistant que celui dans lequel est fabriqué le poussoir. Le blocage de la chape est ainsi particulièrement solide et peu sujet à l'usure.Ring means any piece provided with an opening to accommodate the pusher. So, the ring is more mechanically resistant than the housing and can be made of a material as resistant as that in which the pusher is manufactured. The locking of the yoke is thus particularly strong and not subject to wear.

Selon un premier mode de réalisation particulier, la bague est insérée à force dans un lamage de la partie de boîtier.According to a first particular embodiment, the ring is forced into a counterbore of the housing part.

Selon un deuxième mode de réalisation particulier, la partie de boîtier est surmoulée sur la bague.According to a second particular embodiment, the housing portion is overmolded on the ring.

Selon un troisième mode de réalisation particulier, la partie de boîtier comprend au moins une portion qui a été déformée pour maintenir la bague en position.According to a third particular embodiment, the housing portion comprises at least one portion that has been deformed to hold the ring in position.

De préférence, la bague comprend des moyens de son immobilisation en rotation par rapport à la partie de boîtier , ces moyens comprenant un contour externe non circulaire et avantageusement au moins une excroissance en saillie vers l'extérieur pour prendre appui contre une surface du boîtier.Preferably, the ring comprises means for immobilizing it in rotation with respect to the housing part, these means comprising a non-circular outer contour and advantageously at least one outwardly protruding protrusion for bearing against a surface of the housing.

Le contour non circulaire peut s'étendre sur tout ou partie de l'épaisseur de la bague. Les excroissances permettent de bénéficier d'un effet de bras de levier et d'avoir une surface relativement grande pour répartir les contraintes que va exercer la bague sur le boîtier lorsque celui-ci sera sollicité en rotation par rapport à la clé.The non-circular contour may extend over all or part of the thickness of the ring. The protrusions make it possible to benefit from a leverage effect and to have a relatively large surface area to distribute the stresses that the ring will exert on the housing when it is urged to rotate relative to the key.

D'autres caractéristiques et avantages ressortiront à la lecture de la description qui suit d'un mode de réalisation particulier non limitatif de l'invention.Other characteristics and advantages will become apparent on reading the following description of a particular non-limiting embodiment of the invention.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

La clé conforme à l'invention est ici décrite en tant qu'un dispositif d'actionnement de serrures telles que celles d'un véhicule automobile. En particulier, la clé est utilisable pour le verrouillage et le déverrouillage des ouvrants (portières, malle,...) et de la colonne de direction, ainsi que l'actionnement du contacteur d'allumage.The key according to the invention is here described as a device for actuating locks such as those of a motor vehicle. In particular, the key can be used for locking and unlocking the doors (doors, trunk, ...) and the steering column, as well as the actuation of the ignition switch.

En référence aux figures 1 et 2, la clé, généralement désignée en 1, est montée dans un boîtier 2 pour pivoter entre une position escamotée dans un renfoncement latéral 3 du boîtier 2 et une position sortie dans laquelle la clé 1 s'étend à 180° par rapport à sa position escamotée. Le boîtier 2 est ici formé d'un réceptacle 4 fermé par un couvercle 5 et renferme ici un module électronique de télécommande agencé de manière connue en elle-même pour actionner à distance un dispositif centralisé de verrouillage et déverrouillage des ouvrants du véhicule automobile. Le module électronique de commande peut également être agencé pour activer et désactiver une alarme, allumer et éteindre les projecteurs du véhicule...With reference to Figures 1 and 2 , the key, generally designated 1, is mounted in a housing 2 to pivot between a retracted position in a lateral recess 3 of the housing 2 and an extended position in which the key 1 extends 180 ° relative to its retracted position . The housing 2 is here formed of a receptacle 4 closed by a cover 5 and here encloses an electronic remote control module arranged in a manner known per se for remotely actuating a centralized locking and unlocking device for the openings of the motor vehicle. The electronic control module can also be arranged to activate and deactivate an alarm, turn on and off the vehicle's headlamps ...

Le réceptacle 4 et le couvercle 5 sont ici réalisés en un matériau thermoplastique, par injection.The receptacle 4 and the lid 5 are here made of a thermoplastic material, by injection.

Le couvercle 5 possède une lumière 27 ayant un axe central 11 qui est perpendiculaire à la direction longitudinale de la clé 1 et qui est confondu avec l'axe de pivotement de la clé 1.The cover 5 has a slot 27 having a central axis 11 which is perpendicular to the longitudinal direction of the key 1 and coincides with the pivot axis of the key 1.

Une bague 13 est reçue dans un lamage 14 ménagé dans le couvercle 5 coaxialement à la lumière 27 du couvercle 5 du boîtier 2. Des encoches 26 s'étendant à 180° l'une de l'autre sont réalisées dans l'épaisseur de la bague 13 et débouchent sur une circonférence intérieure de la bague 13 et sur la face de la bague 13 tournée vers le réceptacle 4 (les encoches 26 ont une hauteur inférieure à l'épaisseur de la bague 13). La bague 13 a un pourtour extérieur non circulaire ici pourvu d'un méplat 15 s'étendant au contact d'une face plane du lamage 14 pour immobiliser en rotation la bague 13 par rapport au couvercle 5.A ring 13 is received in a recess 14 countersunk in the cover 5 coaxially with the light 27 of the cover 5 of the housing 2. Notches 26 extending 180 ° from one another are formed in the thickness of the ring 13 and open on an inner circumference of the ring 13 and on the face of the ring 13 facing the receptacle 4 (the notches 26 have a height less than the thickness of the ring 13). The ring 13 has a non-circular outer circumference here provided with a flat portion 15 extending in contact with a flat face of the counter-hole 14 to immobilize the ring 13 in rotation with respect to the lid 5.

La bague 14 est ici réalisée en métal, et plus particulièrement en un alliage à base de zinc incorporant notamment de l'aluminium, tel que celui commercialisé sous la marque ZAMAK. La bague 13 est réalisée par décolletage, frappe à froid, ou découpe emboutissage. Le couvercle 5 est ici surmoulé sur la bague 13. La bague 13 a ainsi une dureté supérieure à celle du matériau thermoplastique constituant le boîtier 2. Plus généralement, la bague 13 a une résistance mécanique supérieure à celle du boîtier 2.The ring 14 is here made of metal, and more particularly of a zinc-based alloy incorporating in particular aluminum, such as that marketed under the trademark ZAMAK. The ring 13 is made by bar turning, cold stamping, or cutting stamping. The cover 5 is here overmolded on the ring 13. The ring 13 thus has a hardness greater than that of the thermoplastic material constituting the casing 2. More generally, the ring 13 has a greater mechanical strength than that of the casing 2.

La clé 1 comprend une extrémité 6 fixée dans une chape généralement désignée en 7 et reçues entre deux joues parallèles du boîtier à une extrémité du renfoncement latéral 3 pour pivoter entre la position sortie et la position escamotée de la clé 1.The key 1 comprises an end 6 fixed in a yoke generally designated 7 and received between two parallel flanges of the housing at one end of the lateral recess 3 for pivoting between the extended position and the retracted position of the key 1.

La chape 7 possède deux faces externes 8, 9 parallèles et opposées l'une à l'autre. La chape 7 comporte un alésage 10 ayant un axe confondu avec l'axe central 11 qui perpendiculaire aux faces externes 8, 9. L'alésage 10 présente une section transversale circulaire et débouche sur les faces externes 8, 9.The yoke 7 has two external faces 8, 9 parallel and opposite to each other. The yoke 7 has a bore 10 having an axis coinciding with the central axis 11 which perpendicular to the outer faces 8, 9. The bore 10 has a circular cross section and opens out onto the outer faces 8, 9.

Le logement 10 de la chape 7 accueille un élément d'articulation généralement désigné en 16 et un poussoir de commande généralement désigné en 17 entre lesquels s'étend un ressort 18.The housing 10 of the yoke 7 accommodates a hinge member generally designated 16 and a control pusher generally designated 17 between which extends a spring 18.

L'élément d'articulation 16 a une forme extérieure cylindrique à contour circulaire et possède une extrémité 19 reçue dans une cavité 20 de l'extrémité du renfoncement latéral 3 recevant la chape 7 et à l'opposé une extrémité 21 reçue à pivotement dans le logement 10 de la chape 7. L'extrémité 19 de l'élément d'articulation 16 et la cavité 20 possèdent des reliefs de forme complémentaire immobilisant l'élément d'articulation 16 en rotation par rapport au boîtier 2. L'extrémité 19 peut ainsi par exemple comprendre des méplats en contact avec des surfaces planes correspondantes de la cavité 20 ou une empreinte excentrée recevant un relief correspondant en saillie de la cavité 20. L'extrémité 21 a une forme extérieure sensiblement cylindrique à section circulaire.The hinge element 16 has a cylindrical outer shape with a circular contour and has an end 19 received in a cavity 20 of the end of the lateral recess 3 receiving the yoke 7 and on the opposite end 21 received pivotally in the housing 10 of the yoke 7. The end 19 of the hinge member 16 and the cavity 20 have reliefs of complementary shape immobilizing the hinge member 16 in rotation relative to the housing 2. The end 19 can thus for example comprise flats in contact with corresponding flat surfaces of the cavity 20 or an eccentric cavity receiving a corresponding relief projecting from the cavity 20. The end 21 has a substantially cylindrical outer shape with circular section.

Le poussoir de commande 17 a une surface extérieure cylindrique circulaire et possède une portion d'extrémité 22 reçue dans le logement 10 et une portion d'extrémité 23 opposée s'étendant en saillie du logement 10 et du couvercle 5 en passant par la lumière 27 de ce dernier. Deux ergots 24 décalés angulairement l'un par rapport à l'autre de 170° s'étendent en saillie de la portion d'extrémité 22 et sont reçus dans des rainures 12 ménagées de manière connue en soi dans le logement 10 avec une forme en baïonnette pour autoriser un coulissement du poussoir entre une position de blocage du pivotement de la chape 7 et une position de libération du pivotement de la chape 7.The control pusher 17 has a circular cylindrical outer surface and has an end portion 22 received in the housing 10 and an opposite end portion 23 projecting from the housing 10 and the cover 5 through the light 27. of the last. Two lugs 24 offset angularly relative to each other by 170 ° project from the end portion 22 and are received in grooves 12 arranged in a manner known per se in the housing 10 with a shape of bayonet to allow a sliding of the pusher between a locking position of the pivoting of the yoke 7 and a release position of the pivoting of the yoke 7.

Dans la position de blocage, deux ergots 25 s'étendant en saillie de la portion d'extrémité 23 en retrait de la face terminale de celle-ci sont engagés dans les deux encoches 26.In the locking position, two lugs 25 protruding from the end portion 23 set back from the end face thereof are engaged in the two notches 26.

Dans la position de libération du pivotement de la chape 7, le poussoir de commande 17 est enfoncé et les ergots 25 sont dégagés des encoches 26.In the position of release of the pivoting of the yoke 7, the control pusher 17 is depressed and the lugs 25 are disengaged from the notches 26.

L'élément d'articulation 16 et le poussoir de commande 17 définissent un axe d'articulation et de pivotement de la chape 7 par rapport au boîtier 2. Cet axe d'articulation est confondu avec l'axe central 11.The hinge element 16 and the control pusher 17 define an axis of articulation and pivoting of the yoke 7 with respect to the housing 2. This hinge axis coincides with the central axis 11.

Le ressort 18 a des extrémités immobilisées en rotation dans l'élément d'articulation 16 et dans le poussoir de commande 17. Le poussoir de commande 17 comprend ici une fente 27 recevant l'extrémité correspondante du ressort 18 pour immobiliser cette extrémité en rotation par rapport au poussoir. Le ressort 18 est un ressort hélicoïdal agencé pour travailler en compression de manière qu'il tend à ramener le poussoir de commande 17 dans sa position de blocage. En outre, lorsque la chape 7 est dans la position escamotée, le ressort 18 a subi une torsion d'au moins 180° par rapport à son état de repos. Le ressort 18 est ainsi également agencé pour travailler en torsion de manière qu'il tend à maintenir les ergots 24 en appui contre le flanc des rainures 12, et ainsi à ramener la chape 7 dans la position sortie de la clé 1.The spring 18 has ends immobilized in rotation in the articulation member 16 and in the control pusher 17. The control pusher 17 here comprises a slot 27 receiving the corresponding end of the spring 18 to immobilize this end in rotation by compared to the pusher. The spring 18 is a helical spring arranged to work in compression so that it tends to return the control pusher 17 to its locking position. In addition, when the yoke 7 is in the retracted position, the spring 18 has undergone a twist of at least 180 ° with respect to its rest state. The spring 18 is thus also arranged to work in torsion so that it tends to hold the pins 24 in abutment against the side of the grooves 12, and thus to bring the yoke 7 into the extended position of the key 1.

On notera qu'en fonctionnement le poussoir de commande 17 dans sa position de blocage assure aussi bien le maintien de la chape 7 dans la position sortie de la clé 1 que dans la position escamotée de la clé 1. Si les encoches 26 sont délimitées latéralement par des flancs parallèles à la direction de coulissement, il est nécessaire d'enfoncer le poussoir de commande 17 dans sa position de libération pour ramener la clé 1 de sa position sortie à sa position escamotée ou inversement.Note that in operation the control pushbutton 17 in its locking position ensures both the maintenance of the yoke 7 in the output position of the key 1 as in the retracted position of the key 1. If the notches 26 are laterally delimited by flanks parallel to the direction of sliding, it is necessary to push the control button 17 in its release position to return the key 1 from its extended position to its retracted position or vice versa.

Dans la variante de la figure 3, les encoches 26 de la bague 13 ont une hauteur égale à l'épaisseur de la bague 13 de sorte que les encoches 26 débouchent sur les deux faces de la bague 13, en facilitant la fabrication, notamment par découpe emboutissage.In the variant of the figure 3 , the notches 26 of the ring 13 have a height equal to the thickness of the ring 13 so that the notches 26 open on both sides of the ring 13, facilitating the manufacture, in particular by cutting stamping.

La bague 13 possède deux excroissances latérales 28 qui s'étendent en saillie extérieure de la bague 13 et qui sont pourvues chacune d'une encoche 29. La partie du couvercle 5 recevant la bague 13 possède une surface latérale s'étendant en regard d'au moins une des excroissances latérales 28 de telle manière que cette excroissance latérale 28 vienne en butée contre cette surface du couvercle 5 s'opposant à un pivotement relatif de la bague 13 et du couvercle 5. Les encoches 29 reçoivent chacune un pion 30 s'étendant en saillie de la surface interne du couvercle 5. Chaque pion 30 a une tête qui s'étend en saillie de la bague 13 et qui a été déformée à chaud (ici aplatie) pour plaquer la bague 13 contre la surface interne du couvercle 5.The ring 13 has two lateral protuberances 28 which extend outwardly from the ring 13 and which are each provided with a notch 29. The part of the cover 5 receiving the ring 13 has a lateral surface extending facing at least one of the lateral protuberances 28 such that this lateral protrusion 28 abuts against this surface of the cover 5 opposing a relative pivoting of the ring 13 and the lid 5. The notches 29 each receive a pin 30 projecting from the inner surface 5. Each peg 30 has a head which protrudes from the ring 13 and which has been deformed hot (here flattened) to press the ring 13 against the inner surface of the cover 5.

En variante, les pions 30 peuvent être emmanchés à force dans des orifices de la bague 13.In a variant, the pins 30 can be press-fitted into holes in the ring 13.

Dans la variante de la figure 4, la bague 13 est insérée à force dans le lamage 14, le lamage 14 ayant, perpendiculairement à l'axe central 11, des dimensions inférieures aux dimensions extérieures de la bague 13, la bague 13 étant maintenue dans le lamage par déformation élastique. Pour faciliter l'insertion à force, il est prévu des chanfreins d'entrée sur le lamage et la bague 13.In the variant of the figure 4 , the ring 13 is inserted by force in the counterbore 14, the counterbore 14 having, perpendicular to the central axis 11, smaller dimensions than the outer dimensions of the ring 13, the ring 13 being held in the counterbore by elastic deformation. To facilitate insertion by force, chamfers are provided on the countersink and the ring 13.

La bague 13 possède des redans périphériques 31 destinés à coopérer avec des reliefs 32 de forme complémentaire du lamage 14 pour l'immobiliser en rotation par rapport au couvercle 5. Les redans 31 s'étendent ici sur une partie seulement de l'épaisseur de la bague 13, du côté du fond du lamage 14, et de manière symétrique par rapport à un plan diamétral de la bague 13.The ring 13 has peripheral rims 31 intended to cooperate with reliefs 32 of complementary shape of the counterbore 14 to immobilize it in rotation relative to the cover 5. The struts 31 here extend over only a portion of the thickness of the ring 13, on the side of the bottom of the counterbore 14, and symmetrically with respect to a diametral plane of the ring 13.

En variante encore, il est possible de fixer la bague 13 au couvercle 5 par soudage par ultra-sons, friction ou induction, par collage, ou tout autre mode de fixation permettant d'immobiliser la bague 13 par rapport au couvercle 5. La bague peut présenter une surface externe à reliefs, tel qu'un moletage, pour favoriser son maintien en position.In another variant, it is possible to fix the ring 13 to the lid 5 by ultrasonic welding, friction or induction, by gluing, or any other method of fixing to immobilize the ring 13 relative to the lid 5. The ring may have an outer surface relief, such as a knurling, to promote its retention in position.

La bague 13 peut être fixée dans un lamage ou directement sur le fond du couvercle.The ring 13 can be fixed in a counterbore or directly on the bottom of the cover.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications.Of course, the invention is not limited to the embodiment described and variants may be provided without departing from the scope of the invention as defined by the claims.

En variante, si l'on veut pouvoir ramener la clé 1 de sa position sortie à sa position escamotée sans devoir actionner le poussoir de commande 17, le flanc des encoches 26 se trouvant du côté de la position escamotée (c'est à dire le flanc contre lequel chaque ergot 25 vient en butée lorsqu'on tente de ramener la clé 1 de sa position sortie à sa position escamotée) peut être incliné pour former par glissement sur l'ergot 25 une came de déplacement du poussoir de commande 17 dans sa position de libération.In a variant, if it is desired to be able to return the key 1 from its extended position to its retracted position without having to actuate the control push-button 17, the side of the notches 26 lying on the side of the retracted position (ie the side against which each lug 25 abuts when attempting to return the key 1 from its extended position to its retracted position) can be inclined to form by sliding on the lug 25 a cam of displacement of the control pusher 17 in its release position.

En outre, le boîtier 2 peut avoir d'autres formes que celle représentée et par exemple une forme cylindrique et les positions escamotée et sortie de la clé peuvent être décalées angulairement l'une de l'autre d'un angle différent de 180° et par exemple 90° ou 120°.In addition, the housing 2 may have other shapes than the one shown and for example a cylindrical shape and the retracted and exit positions of the key can be angularly offset from each other by an angle other than 180 ° and for example 90 ° or 120 °.

De plus, l'élément d'articulation peut être en une seule pièce avec le boîtier.In addition, the hinge member can be in one piece with the housing.

Il est possible de prévoir une seule encoche ou plus de deux. Les encoches sont réalisées sur une hauteur inférieure à une épaisseur de la bague ou sur toute l'épaisseur de la bague pour déboucher sur les deux faces de la bague.It is possible to provide a single notch or more than two. The notches are made on a height less than a thickness of the ring or over the entire thickness of the ring to open on both sides of the ring.

La bague peut être en une ou plusieurs parties, être réalisée en métal ou tout autre matériau plus résistant mécaniquement que la partie de boîtier à laquelle elle est fixée.The ring may be in one or more parts, be made of metal or any other mechanically stronger material than the housing part to which it is attached.
