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 une première joue et une deuxième joue d'un boîtier pour pivoter entre une position escamotée et une position sortie autour d'un pivot et d'un poussoir de commande du pivotement de la clé qui sont montés dans un alésage de la chape et respectivement dans un logement de la première joue et un logement de la deuxième joue. Le poussoir de commande est monté dans l'alésage pour être solidaire en pivotement de la chape et pour coulisser entre une position en saillie du boîtier, ou position de maintien, dans laquelle le poussoir maintient la chape dans la position escamotée et une position de libération du pivotement de la chape. Le pivot est indexé en rotation dans le logement de la première joue pour former un organe d'indexation d'un ressort intercalé entre le pivot et le poussoir de commande pour rappeler élastiquement la chape dans la position sortie et le poussoir de commande dans la position de maintien de la chape. Une telle clé est par exemple connue de EP 1526232 A .There are keys having an integral end of a yoke mounted between a first cheek and a second cheek of a housing for pivoting between a retracted position and an extended position around a pivot and a control pushbutton of the pivoting of the key that are mounted in a bore of the yoke and respectively in a slot of the first cheek and a slot of the second cheek. The control pusher is mounted in the bore to be integral in pivoting the yoke and for sliding between a projecting position of the housing, or holding position, in which the pusher maintains the yoke in the retracted position and a release position. pivoting of the screed. The pivot is indexed in rotation in the housing of the first cheek to form an indexing member of a spring interposed between the pivot and the control pusher for resiliently returning the yoke in the extended position and the control pusher in the position keeping the screed. Such a key is for example known from EP 1526232 A .

Dans ces clés, le pivot, le ressort et le poussoir de commande sont montés successivement après mise en place de la chape entre les joues du boîtier. L'indexation du pivot résulte de l'emboîtement d'un index en saillie du logement dans un renfoncement du pivot. Or, on s'est aperçu que lorsque la clé subit un choc dans le sens de l'axe de pivotement de la chape, par exemple lorsqu'elle échappe à son utilisateur et tombe au sol, il existe un risque que le pivot se rapproche du bouton poussoir dégageant ainsi l'index de son renfoncement. Le ressort provoque alors un pivotement du pivot désarmant le ressort et empêchant celui-ci d'exercer sa fonction de rappel de la chape en position sortie.In these keys, the pivot, the spring and the control pusher are mounted successively after placing the yoke between the cheeks of the housing. The indexing of the pivot results from the fitting of an index protruding from the housing in a recess of the pivot. However, it has been found that when the key is impacted in the direction of the pivot axis of the yoke, for example when it escapes the user and falls to the ground, there is a risk that the pivot is approaching push button thus releasing the index of its recess. The spring then causes pivoting of the pivot disarming the spring and preventing it from exercising its function of reminder of the clevis in the out position.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Un but de l'invention est de fournir un moyen permettant de fiabiliser le rappel de la chape en position sortie.An object of the invention is to provide a means to make reliable the return of the yoke in the extended position.

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 entre une première joue et une deuxième joue d'un boîtier pour pivoter entre une position escamotée et une position sortie autour d'un pivot et d'un poussoir de commande du pivotement de la clé qui sont montés dans un alésage de la chape et respectivement dans un logement de la première joue et un logement de la deuxième joue, le poussoir de commande étant solidaire en pivotement de la chape et le pivot étant indexé en rotation dans le logement de la première joue pour former un organe d'indexation d'un ressort intercalé entre le pivot et le poussoir de commande pour rappeler élastiquement la chape dans la position sortie et le poussoir de commande dans une position en saillie du boîtier. Le pivot comprend au moins un ergot reçu dans une rainure du logement de la première joue, et une rainure est ménagée sur une longueur du logement de la deuxième joue, les rainures des logements de la première et de la deuxième joue étant agencées pour déboucher dans des extrémités d'une rainure de l'alésage pour au moins une position intermédiaire de la chape.For this purpose, it is provided, according to the invention, a key having an end secured to a yoke mounted between a first cheek and a second cheek of a housing for pivoting between a retracted position and an output position around a pivot and a button for controlling the pivoting of the key which are mounted in a bore of the yoke and respectively in a housing of the first cheek and a housing of the second cheek, the control pusher being pivotally secured to the yoke and the pivot being indexed in rotation in the housing of the first cheek to form an indexing member of a spring interposed between the pivot and the control pusher for resiliently returning the yoke in the extended position and the control pusher in a position protruding from the housing. The pivot comprises at least one lug received in a groove of the housing of the first cheek, and a groove is provided along a length of the housing of the second cheek, the grooves of the housing of the first and second cheek being arranged to open into ends of a groove of the bore for at least one intermediate position of the yoke.

Ainsi, l'ergot du pivot va prendre appui contre la chape et s'opposer à un déplacement du pivot vers le bouton poussoir lorsque la chape n'est pas en position intermédiaire. La communication des rainures pour au moins une position intermédiaire permet le montage du pivot dans le boîtier et la chape. Pour que le pivot soit désindexé à la suite d'un choc, il faudrait que le choc intervienne alors que la clé est dans la position intermédiaire. Or, la clé étant généralement en position sortie ou escamotée, et la position intermédiaire étant une position instable, il est peu probable qu'un choc puisse déplacer le pivot.Thus, the lug of the pivot will bear against the yoke and oppose a displacement of the pivot to the push button when the yoke is not in the intermediate position. The communication of the grooves for at least one intermediate position allows the mounting of the pivot in the housing and the yoke. In order for the pivot to be deindexed following a shock, it would be necessary for the impact to occur while the key is in the intermediate position. However, the key being generally in the extended or retracted position, and the intermediate position being a unstable position, it is unlikely that a shock could move the pivot.

De préférence, les rainures des logements de la première et de la deuxième joue sont agencées pour déboucher dans les extrémités de la rainure de l'alésage pour une pluralité de positions intermédiaires contenues dans une plage angulaire de la chape.Preferably, the grooves of the housings of the first and second flanges are arranged to open into the ends of the groove of the bore for a plurality of intermediate positions within an angular range of the yoke.

La plage angulaire permet de faciliter le montage du pivot sans trop augmenter le risque d'une suppression de l'indexation à la suite d'un choc.The angular range facilitates the mounting of the pivot without increasing the risk of a removal of the indexing after an impact.

Selon un mode de réalisation particulier, le poussoir de commande possède au moins un ergot maintenu par l'action du ressort dans un tronçon borgne de la rainure de l'alésage, le tronçon borgne ayant une entrée débouchant avec un angle dans un tronçon principal de la rainure.According to a particular embodiment, the control pusher has at least one lug held by the action of the spring in a blind section of the groove of the bore, the blind section having an inlet opening with an angle in a main section of the groove.

Ainsi, la rainure de l'alésage permet également le montage du poussoir de commande. Le tronçon borgne accueille l'ergot du poussoir de commande en opération et permet son coulissement entre sa position en saillie et une position de libération du pivotement de la chape.Thus, the groove of the bore also allows the mounting of the control pusher. The blind section receives the lug of the control pushbutton in operation and allows it to slide between its projecting position and a release position of the pivoting of the yoke.

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.

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 central 11 perpendiculaire à la direction longitudinale de la clé 1 et 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 comprises a bore 10 having a central axis 11 perpendicular to the longitudinal direction of the key 1 and to the outer faces 8, 9. The bore 10 has a circular cross section and opens on the outer faces 8, 9.

Des rainures 12 sont ménagées dans l'alésage 10 pour avoir des extrémités débouchant sur les faces externes 8 et 9. Les rainures 12 sont décalées angulairement l'une par rapport à l'autre d'un angle α valant ici 170° environ. Ce décalage angulaire inférieur à 180° permet d'éviter qu'une des rainures n'empiète sur la zone de la chape 7 dévolue à l'extrémité 6 de la clé 1 tout en ayant une chape 7 relativement compacte.Grooves 12 are formed in the bore 10 to have ends opening on the outer faces 8 and 9. The grooves 12 are angularly offset relative to each other by an angle α of about 170 °. This angular offset of less than 180 ° allows to prevent one of the grooves impinges on the area of the yoke 7 devolving at the end 6 of the key 1 while having a relatively compact yoke 7.

Chaque rainure 12 comprend un tronçon principal 13 débouchant par un tronçon terminal 15.1 sur la face externe 8 de la chape 7 et par un tronçon terminal 15.2 sur la face externe 9 de la chape 7. Un tronçon borgne 14 débouche dans le tronçon principal 13.Each groove 12 comprises a main section 13 opening through a terminal section 15.1 on the outer face 8 of the yoke 7 and by a terminal section 15.2 on the outer face 9 of the yoke 7. A blind section 14 opens into the main section 13.

Les tronçons terminaux 15.1, 15.2 s'étendent parallèlement à l'axe central 11 et le tronçon central 13 s'étend selon une circonférence du logement 10. Le tronçon terminal 15.2 est situé derrière le tronçon terminal 15.1 par référence au sens de pivotement de la clé 1 de sa position escamotée vers sa position sortie.The terminal sections 15.1, 15.2 extend parallel to the central axis 11 and the central section 13 extends along a circumference of the housing 10. The terminal section 15.2 is located behind the terminal section 15.1 with reference to the direction of rotation of the key 1 from its retracted position to its extended position.

Le tronçon borgne 14 s'étend parallèlement à l'axe central 11 dans le prolongement du tronçon terminal 15.2 vers la joue 4.2 (ceci permet de faciliter la réalisation de la rainure comme cela sera expliqué par la suite).The blind section 14 extends parallel to the central axis 11 in the extension of the terminal section 15.2 to the cheek 4.2 (this facilitates the realization of the groove as will be explained later).

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

Le pivot 16 a une forme extérieure cylindrique à contour circulaire et possède une extrémité 19 reçue dans un logement 20 de la joue 4.1 et à l'opposé une extrémité 21 reçue à pivotement dans l'alésage 10 de la chape 7. L'extrémité 19 du pivot 16 et le logement 20 possèdent des reliefs d'indexation de forme complémentaire immobilisant le pivot 16 en rotation par rapport au boîtier 2. L'extrémité 19 a ainsi un fond pourvu d'une encoche 28 recevant une languette 29 s'étendant en saillie du logement 20. En variante, l'extrémité 19 peut par exemple comprendre des méplats latéraux en contact avec des surfaces planes correspondantes du logement 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. Deux ergots 30 décalés angulairement l'un par rapport à l'autre de l'angle α s'étendent latéralement en saillie externe du pivot 16 au voisinage de son extrémité 19 et sont reçus dans des rainures 31 s'étendant axialement dans le logement 20 en décalage angulaire l'une par rapport à l'autre d'un angle α. Les ergots 30 coopèrent avec la face externe 9 pour former une butée s'opposant à l'extraction du pivot 16 hors du logement 20.The pivot 16 has a cylindrical outer shape with a circular contour and has an end 19 received in a housing 20 of the flange 4.1 and opposite an end 21 pivotally received in the bore 10 of the yoke 7. The end 19 of the pivot 16 and the housing 20 have indexing reliefs of complementary shape immobilizing the pivot 16 in rotation relative to the housing 2. The end 19 thus has a bottom provided with a notch 28 receiving a tongue 29 extending in As a variant, the end 19 may for example comprise lateral flats in contact with corresponding flat surfaces of the housing 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. Two lugs 30 angularly offset relative to each other of the angle α extend laterally external projection of the pivot 16 in the vicinity of its end 19 and are received in grooves 31 extending axially in the housing 20 angularly offset relative to each other by an angle α. The lugs 30 cooperate with the outer face 9 to form a stop opposing the extraction of the pivot 16 from the housing 20.

Le poussoir de commande 17 a une surface extérieure cylindrique circulaire et possède une portion d'extrémité 22 reçue dans l'alésage 10 et une portion d'extrémité 23 opposée s'étendant en saillie de l'alésage 10, d'un logement 32 de la joue 4.2 et du couvercle 5 en passant par une lumière 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 les tronçons borgnes 14 des rainures 12 pour coulisser entre une position de blocage du pivotement de la chape 7 et une position de libération du pivotement de la chape 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 deux encoches 26 ménagées au voisinage de la lumière du couvercle 5 du boîtier 2 à 180° l'une de l'autre. 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.The control pusher 17 has a circular cylindrical outer surface and has an end portion 22 received in the bore 10 and an opposite end portion 23 projecting from the bore 10, a housing 32 of the cheek 4.2 and cover 5 through a light of the latter. Two lugs 24 angularly offset relative to each other by 170 ° extend projecting from the end portion 22 and are received in the blind portions 14 of the grooves 12 to slide between a locking position of the pivoting of the the clevis 7 and a release position of the pivoting of the yoke 7. In the locking position, two lugs 25 projecting from the end portion 23 set back from the end face thereof are engaged in two notches 26 formed in the vicinity of the light of the cover 5 of the housing 2 180 ° from one another. 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.

Le pivot 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 pivot 16 and the control pusher 17 define an axis of articulation and pivoting of the yoke 7 relative to the housing 2. This hinge axis coincides with the central axis 11.

Le logement 32 de la joue 4.2 présente des rainures s'étendant axialement dans le logement 32 avec un décalage angulaire de α l'une par rapport à l'autre. Les rainures 31 des logements 31, 32 de la première et de la deuxième joue 4.1, 4.2 sont agencées pour déboucher respectivement dans les tronçons terminaux 15.1, 15.2 de la rainure 12 de l'alésage 10 pour une pluralité de positions intermédiaires contenues dans une plage angulaire de la chape 7, la plage angulaire étant inférieure à 90° environ et ici de 35°. La position sortie étant à 180° environ de la position escamotée, la plage angulaire s'étend entre 90° et 125°.The housing 32 of the cheek 4.2 has grooves extending axially in the housing 32 with an angular offset of α relative to each other. The grooves 31 of the housings 31, 32 of the first and second cheeks 4.1, 4.2 are arranged to open respectively into the end sections 15.1, 15.2 of the groove 12 of the bore 10 for a plurality of intermediate positions within an angular range of the yoke 7, the angular range being less than 90 ° and 35 ° here. As the extended position is approximately 180 ° from the retracted position, the angular range extends between 90 ° and 125 °.

Le ressort 18 a des extrémités immobilisées en rotation dans le pivot 16 et dans le poussoir de commande 17. Le pivot 16 et le poussoir de commande 17 comprennent ici une fente 34, 27 recevant l'extrémité correspondante du ressort 18 pour immobiliser cette extrémité en rotation par rapport au pivot et au poussoir de commande respectivement. 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 28 des tronçons borgnes 14, 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 pivot 16 and in the control pusher 17. The pivot 16 and the control pusher 17 here comprise a slot 34, 27 receiving the corresponding end of the spring 18 to immobilize this end. rotation relative to the pivot and the control pusher respectively. 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 lugs 24 in abutment against the side 28 of the blind sections 14, and thus to bring the yoke 7 into the extended position of the key 1.

On notera qu'en fonctionnement le poussoir de commande 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. En revanche, 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.Note that in operation the control pusher 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 delimited laterally 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. On the other hand, 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 control pushbutton 17 in its release position.

En cas de déplacement du pivot 16 vers le poussoir de commande 17, les ergots 30 viennent buter contre la face externe 9 de la chape 7, empêchant un désengagement relatif de la languette 29 hors de l'encoche 28.In case of displacement of the pivot 16 towards the control pusher 17, the lugs 30 abut against the outer face 9 of the yoke 7, preventing a relative disengagement of the tongue 29 from the notch 28.

Le montage de la clé 1 dans le boîtier 2 est réalisé en introduisant la chape 7 équipée de la clé 1 entre les joues 4.1, 4.2 du réceptacle 4 du boîtier 2. Puis, tout en maintenant la chape 7 en position intermédiaire dans la plage angulaire comprise entre 90° et 125°, on dispose, d'une part, le pivot 16 dans le logement 20 et l'alésage 10 et d'autre part, le poussoir de commande 17 dans l'alésage 10 et le logement 32 en ayant interposé le ressort 18 entre le pivot 16 et le poussoir de commande 17. On notera qu'il est nécessaire de faire pivoter le pivot 16 ou la chape 7 pour amener les ergots 30 des tronçons terminaux 15.1 vers les tronçons terminaux 15.2 en passant dans les tronçons principaux 13. L'introduction des ergots 24 dans les tronçons borgnes 14 est réalisée en faisant préalablement pivoter le poussoir de commande 17 par rapport au boîtier 2 et à la chape 7 pour engager les ergots 24 dans les portions terminales 13.1. Le sens de pivotement est le même que celui qui permet à la chape 7 d'aller de la position sortie à la position escamotée : ce pivotement doit être supérieur à 180° pour exercer une précontrainte en torsion sur le ressort 18. Le poussoir de commande 17 est ensuite enfoncé pour amener le poussoir de commande 17 dans le tronçon central 13. Le ressort 18 se détendant légèrement en torsion (la torsion doit encore être de 180° par rapport à son état de repos) amène les ergots 24 dans les tronçons borgnes 14 et se détendant en compression ramène le poussoir de commande 17 vers sa position de blocage.The mounting of the key 1 in the housing 2 is performed by introducing the yoke 7 equipped with the key 1 between the flanges 4.1, 4.2 of the receptacle 4 of the housing 2. Then, while maintaining the yoke 7 in the intermediate position in the angular range between 90 ° and 125 °, one has, on the one hand, the pivot 16 in the housing 20 and the bore 10 and on the other hand, the control pusher 17 in the bore 10 and the housing 32 having interposed the spring 18 between the pivot 16 and the control pusher 17. Note that it is necessary to rotate the pivot 16 or the yoke 7 to bring the lugs 30 of the terminal sections 15.1 to the terminal sections 15.2 passing through the main sections 13. The introduction of the lugs 24 in the blind sections 14 is achieved by first pivoting the control pushbutton 17 relative to the housing 2 and the yoke 7 to engage the lugs 24 in the end portions 13.1. The pivoting direction is the same as that which allows the yoke 7 to go from the extended position to the retracted position: this pivoting must be greater than 180 ° to exert a torsional preload on the spring 18. The control pusher 17 is then depressed to bring the control pusher 17 into the central section 13. The spring 18 which relaxes slightly in torsion (the torsion must still be 180 ° with respect to its rest state) brings the pins 24 into the blind sections 14 and relaxing in compression brings the control pushbutton 17 to its locking position.

On remarquera que le poussoir de commande 17 peut être démonté en effectuant les opérations inverses.It will be noted that the control pusher 17 can be disassembled by performing the reverse operations.

On notera que le tronçon terminal 15.2 débouche par une extrémité sur la face externe 9 et par l'autre extrémité dans le tronçon central 13 et dans le tronçon borgne 14 de manière à faciliter la fabrication par moulage de la chape 7. Lors du moulage de la chape 7, l'alésage 10 est réalisé au moyen de deux noyaux mobiles coaxiaux dont les extrémités sont amenées en contact. L'un des noyaux comporte des languettes en saillie externe pour former les tronçons terminaux 15.1 et l'autre des noyaux comporte des languettes en saillie externe pour former les tronçons terminaux 15.2 et les tronçons borgnes 14. Chaque tronçon central 13 est formé à l'intersection des tronçons terminaux et est principalement délimité par le fond du tronçon terminal 15.1 et le flanc opposé du tronçon terminal 15.2.Note that the terminal section 15.2 opens at one end on the outer face 9 and the other end in the central section 13 and in the section blind eye 14 so as to facilitate the manufacture by molding of the yoke 7. When molding the yoke 7, the bore 10 is made by means of two coaxial mobile cores whose ends are brought into contact. One of the cores comprises tongues projecting from outside to form the terminal sections 15.1 and the other of the cores comprises tongues projecting from outside to form the terminal sections 15.2 and the blind sections 14. Each central section 13 is formed at the intersection of the terminal sections and is mainly delimited by the bottom of the terminal section 15.1 and the opposite side of the terminal section 15.2.

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 particulier, bien que la rainure ait été représentée avec une forme en J, la rainure peut avoir une forme en V, le tronçon d'entrée formant un angle aigu avec le tronçon terminal borgne.In particular, although the groove has been shown with a J-shape, the groove may have a V-shape, the inlet portion forming an acute angle with the blind end portion.

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.

La plage angulaire peut être plus restreinte et ne couvrir qu'une seule position intermédiaire.The angular range may be smaller and cover only one intermediate position.

Le pivot 16 peut ne comprendre qu'un ergot, le ou les ergots pouvant avoir des formes diverses comme une forme en oreille, en cylindre...The pivot 16 may comprise only one lug, the lug or lugs may have various shapes such as an ear shape, cylinder shape ...
