Description

La présente invention concerne un verrou à rotor débrayable.The present invention relates to a disengageable rotor lock.

L'invention concerne plus particulièrement un verrou à rotor débrayable du type comportant un rotor tourillonnant dans un stator intermédiaire, lui-même pivotant dans un corps fixe, des organes de verrouillage tels que des paillettes ou des couples de pistons coopérant avec le rotor et le stator intermédiaire pour les solidariser en rotation en l'absence de clé, ou en présence d'une clé non conforme, et pour libérer le rotor en rotation par rapport au stator intermédiaire après introduction d'une clé conforme, et du type comportant un organe d'indexation du stator intermédiaire par rapport au corps fixe.The invention relates more particularly to a disengageable rotor lock of the type comprising a rotor swiveling in an intermediate stator, itself pivoting in a fixed body, locking members such as flakes or pairs of pistons cooperating with the rotor and the intermediate stator to secure them in rotation in the absence of a key, or in the presence of a non-conforming key, and to release the rotor in rotation relative to the intermediate stator after introduction of a conforming key, and of the type comprising a member indexing the intermediate stator relative to the fixed body.

On connaît un exemple de réalisation d'un tel verrou dans lequel l'organe d'indexation est réalisé sous la forme d'un bras agencé dans un logement longitudinal formé dans la paroi périphérique du stator intermédiaire dans lequel il est monté mobile, pivotant, au voisinage de l'une de ses extrémités, autour d'un axe perpendiculaire à l'axe du verrou, entre une position d'indexation, vers laquelle il est rappelé élastiquement, et une position escamotée dans laquelle il est effacé au moins en partie dans le logement, à l'encontre de l'effort élastique de rappel.An exemplary embodiment of such a lock is known, in which the indexing member is produced in the form of an arm arranged in a longitudinal housing formed in the peripheral wall of the intermediate stator in which it is mounted mobile, pivoting, in the vicinity of one of its ends, around an axis perpendicular to the axis of the bolt, between an indexing position, towards which it is spring-loaded, and a retracted position in which it is at least partially erased in the housing, against the elastic return force.

Selon cette conception connue, le bras d'indexation est réalisé sous la forme d'un levier qui est monté pivotant au voisinage de l'une de ses extrémités par rapport au stator intermédiaire et il est prévu un ressort hélicoïdal de compression qui coopère avec la face radiale interne du levier et qui prend appui contre une surface d'appui formée dans le fond du logement pour solliciter élastiquement le levier d'indexation vers sa position d'indexation.According to this known design, the indexing arm is produced in the form of a lever which is pivotally mounted in the vicinity of one of its ends with respect to the intermediate stator and a helical compression spring is provided which cooperates with the internal radial face of the lever and which bears against a bearing surface formed in the bottom of the housing to elastically urge the indexing lever towards its indexing position.

Cette conception est particulièrement complexe dans la mesure où elle nécessite de prévoir des moyens d'articulation de l'extrémité du levier par rapport au stator intermédiaire ainsi qu'un ressort de rappel indépendant de très petite dimension, ces deux composants devront être assemblés et mis en position avec précision dans le verrou lors de l'assemblage des composants de ce dernier. Une telle complexité ne permet notamment pas d'automatiser les opérations d'assemblage.This design is particularly complex insofar as it requires provision for means of articulation of the end of the lever relative to the intermediate stator as well as an independent return spring of very small dimension, these two components must be assembled and put in position precisely in the latch when assembling the components of the latter. Such complexity in particular does not make it possible to automate assembly operations.

Afin de remédier à ces inconvénients, l'invention propose un verrou à rotor débrayable du type mentionné précédemment, caractérisé en ce que le bras d'indexation est réalisé sous la forme d'une poutre qui s'étend longitudinalement pour occuper normalement ladite position d'indexation et qui peut ête déformée élastiquement en flexion pour occuper ladite position escamotée.In order to remedy these drawbacks, the invention provides a disengageable rotor lock of the type mentioned above, characterized in that the indexing arm is produced in the form of a beam which extends longitudinally to normally occupy said position d 'indexing and which can be deformed elastically in bending to occupy said retracted position.

  • les figures 6 à 10 sont des vues similaires à celles des figures 1 à 3 qui illustrent un second mode de réalisation d'un verrou réalisé conformément aux enseignements de l'invention.
Other characteristics and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawings in which:
  • Figure 1 is a schematic view in axial section of a lock produced in accordance with the teachings of the invention;
  • Figure 2 is an enlarged view of a detail of Figure 1 illustrating the indexing member;
  • Figure 3 is a partial sectional view along line 3-3 of Figure 2 in which, as in Figure 2, the indexing member is illustrated in the indexing position;
  • Figure 4 is a view similar to that of Figure 3 illustrating the indexing member in the retracted position;
  • Figure 5 is a perspective view of the lock indexing member made in accordance with the teachings of the invention; and
  • Figures 6 to 10 are views similar to those of Figures 1 to 3 which illustrate a second embodiment of a lock produced in accordance with the teachings of the invention.

Le verrou illustré en particulier à la figure 1 comporte un rotor 10 qui est monté tourillonnant dans un stator intermédiaire 12, ce dernier étant lui-même monté pivotant dans un corps fixe 14 du verrou.The lock illustrated in particular in Figure 1 comprises a rotor 10 which is pivotally mounted in an intermediate stator 12, the latter itself being pivotally mounted in a fixed body 14 of the lock.

Le rotor 10 comporte un canal longitudinal d'introduction de clé 16 dans lequel débouchent des fentes radiales 18.The rotor 10 has a longitudinal key introduction channel 16 into which radial slots 18 open.

Le stator intermédiaire comporte des fentes longitudinales destinées à recevoir les extrémités de paillettes qui sont logées dans les fentes radiales 18.The intermediate stator has longitudinal slots intended to receive the ends of flakes which are housed in the radial slots 18.

En l'absence de clé, ou en présence d'une clé non conforme, les extrémités des paillettes font saillie à l'extérieur de l'enveloppe cylindrique du rotor 10 qui est ainsi rendu solidaire en rotation du stator intermédiaire 12.In the absence of a key, or in the presence of a non-conforming key, the ends of the flakes protrude outside the cylindrical envelope of the rotor 10 which is thus made integral in rotation with the intermediate stator 12.

Bien entendu, les paillettes qui constituent les organes de verrouillage entre le rotor 10 et le stator intermédiaire 12 peuvent être remplacées par tout type d'organes de verrouillage connus, tels que des couples de pistons, des leviers, etc.Of course, the flakes which constitute the locking members between the rotor 10 and the intermediate stator 12 can be replaced by any type of known locking members, such as pairs of pistons, levers, etc.

L'ensemble du verrou est destiné à être fixé par exemple dans une poignée de portière de véhicule automobile.The entire lock is intended to be fixed for example in a door handle of a motor vehicle.

Le rotor 10 comporte, à l'une de ses extrémités, un ergot 24 destiné à coopérer avec un organe de commande 26 dont l'axe 28 est solidaire d'un levier de manoeuvre 30 relié à une tringle d'actionnement (non représentée) du mécanisme de serrure qui équipe la portière.The rotor 10 comprises, at one of its ends, a lug 24 intended to cooperate with a control member 26 whose axis 28 is integral with an operating lever 30 connected to an actuating rod (not shown) of the lock mechanism which equips the door.

Tous ces éléments ne faisant pas partie de la présente invention, ne seront pas décrits ici plus en détail.All these elements not forming part of the present invention will not be described here in more detail.

On se reportera maintenant aux figures 2 à 5 pour la description détaillée du premier mode de réalisation de l'organe d'indexation du stator intermédiaire 12 par rapport au corps de verrou fixe 14.Reference will now be made to FIGS. 2 to 5 for the detailed description of the first embodiment of the indexing member of the intermediate stator 12 relative to the fixed lock body 14.

L'organe d'indexation 32 se présente sous la forme d'un élément unique, moulé en matière plastique, réalisé sous la forme d'une poutre agencée dans un logement longitudinal 33.The indexing member 32 is in the form of a single element, molded in plastic material, produced in the form of a beam arranged in a longitudinal housing 33.

La poutre présente un corps longitudinal 34 qui s'étend parallèlement à l'axe X-X du verrou et dont la section est sensiblement rectangulaire.The beam has a longitudinal body 34 which extends parallel to the axis X-X of the lock and whose section is substantially rectangular.

L'extrémité 36 de gauche du corps 34 de la poutre 32, en considérant la figure 2, est encastrée et est à cet effet reçue dans un évidement formé dans la paroi périphérique 13 du stator intermédiaire 12 dans laquelle il débouche et qui comporte un fond d'évidement 38 contre lequel prend appui la face radiale interne 40 de l'extrémité encastrée 36 de la poutre 32.The left end 36 of the body 34 of the beam 32, considering FIG. 2, is embedded and for this purpose is received in a recess formed in the peripheral wall 13 of the intermediate stator 12 into which it opens and which has a bottom a recess 38 against which the internal radial face 40 of the embedded end 36 of the beam 32 bears.

La face radiale externe 42 de l'extrémité encastrée 36, qui est continue le long du corps 34 de la poutre, est en contact avec la paroi périphérique interne 15 du corps fixe 14 du verrou.The external radial face 42 of the embedded end 36, which is continuous along the body 34 of the beam, is in contact with the internal peripheral wall 15 of the fixed body 14 of the lock.

L'extrémité encastrée 36 est ainsi maintenue radialement dans les deux sens tandis que la poutre est immobilisée longitudinalement au moyen d'un doigt de retenue 44, réalisé venu de matière avec le corps 34, qui s'étend radialement vers l'extérieur et qui est reçu dans un trou de forme complémentaire 46 formé dans la paroi périphérique 13 du stator intermédiaire 12 et qui débouche dans cette dernière.The embedded end 36 is thus held radially in both directions while the beam is immobilized longitudinally by means of a finger. retainer 44, made integrally with the body 34, which extends radially outward and which is received in a hole of complementary shape 46 formed in the peripheral wall 13 of the intermediate stator 12 and which opens into the latter.

La poutre d'indexation est illustrée aux figures 2 et 3 en trait plein dans sa position de repos qu'elle occupe normalement et qui correspond à la position d'indexation de la poutre.The indexing beam is illustrated in Figures 2 and 3 in solid lines in its rest position which it normally occupies and which corresponds to the indexing position of the beam.

Afin d'assurer l'indexation angulaire du stator intermédiaire 12 par rapport au corps fixe 14, la poutre 32 comporte, au voisinage de son extrémité libre 46, une saillie en forme de V inversé qui s'étend radialement vers l'extérieur depuis la face radiale externe 42 de la poutre.In order to ensure the angular indexing of the intermediate stator 12 relative to the fixed body 14, the beam 32 has, in the vicinity of its free end 46, an inverted V-shaped projection which extends radially outwards from the external radial face 42 of the beam.

Dans la position d'indexation, la saillie 48 est reçue dans une rainure longitudinale 58, de profil complémentaire en forme de V inversé, formée dans la paroi interne 15 du corps fixe 14 du verrou.In the indexing position, the projection 48 is received in a longitudinal groove 58, of complementary profile in the form of an inverted V, formed in the internal wall 15 of the fixed body 14 of the latch.

L'extrémité libre 46 de la poutre 32 comporte, sur sa face radiale interne 40, un talon de verrouillage 60 qui, en position d'indexation, s'étend à l'intérieur du logement 33, dans lequel s'étend le corps 34 de la poutre 32, en regard d'une fenêtre 62 formée dans le fond du logement 33 et qui débouche dans la paroi interne 11 du stator intermédiaire 12 en regard d'une encoche 64 formée dans la surface périphérique 9 du rotor 10.The free end 46 of the beam 32 comprises, on its internal radial face 40, a locking heel 60 which, in the indexing position, extends inside the housing 33, in which the body 34 extends of the beam 32, opposite a window 62 formed in the bottom of the housing 33 and which opens into the internal wall 11 of the intermediate stator 12 opposite a notch 64 formed in the peripheral surface 9 of the rotor 10.

La poutre d'indexation 32 peut être fléchie, à partir de sa position d'indexation, et à l'encontre de l'élasticité propre de la poutre, pour venir occuper une position escamotée, illustrée en pointillés à la figure 2, dans laquelle le talon 60 est reçu dans l'encoche 64.The indexing beam 32 can be bent, from its indexing position, and against the inherent elasticity of the beam, to occupy a retracted position, illustrated in dotted lines in FIG. 2, in which the heel 60 is received in the notch 64.

Dans la position de repos du verrou, ou en cas d'introduction d'une clé conforme, l'organe d'indexation 32 occupe la position illustrée en trait plein à la figure 2. Dans cette position, la saillie 48 est reçue à l'intérieur d'une rainure longitudinale 58 du corps fixe 14 et le talon 60 est situé à l'intérieur du logement 33.In the rest position of the lock, or in the event of the insertion of a conforming key, the indexing member 32 occupies the position illustrated in solid lines in FIG. 2. In this position, the projection 48 is received at inside a longitudinal groove 58 of the fixed body 14 and the heel 60 is located inside the housing 33.

Lorsqu'une clé conforme est introduite dans le verrou, les organes de verrouillage constitués par les paillettes sont en concordance avec le rotor 10 et ce dernier est ainsi désolidarisé en rotation du stator intermédiaire 12.When a conforming key is introduced into the lock, the locking members constituted by the flakes are in agreement with the rotor 10 and the latter is thus separated in rotation from the intermediate stator 12.

Dans cette configuration, le talon 60 de l'organe d'indexation 32 n'est plus en vis-à-vis de l'encoche 64 mais est en affleurement avec la surface périphérique pleine 9 du rotor 10 empêchant ainsi tout débrayage intempestif, par exemple lorsque la clé conforme est en butée, à la fin de la course de rotation du rotor.In this configuration, the heel 60 of the indexing member 32 is no longer vis-à-vis the notch 64 but is flush with the solid peripheral surface 9 of the rotor 10 thus preventing any inadvertent disengagement, by example when the conforming key is in abutment, at the end of the rotor rotation stroke.

Le fait de tourner la clé entraîne en rotation le rotor 10 qui, par son ergot 24, entraîne à son tour l'organe de commande 26 et le levier 30 relié au mécanisme de serrure.Turning the key rotates the rotor 10 which, by its lug 24, in turn drives the control member 26 and the lever 30 connected to the lock mechanism.

Si une clé non conforme est introduite dans le rotor 10, les organes de verrouillage maintiennent le rotor 10 solidaire en rotation du stator intermédiaire 12.If a non-conforming key is inserted into the rotor 10, the locking members keep the rotor 10 integral in rotation with the intermediate stator 12.

Lorsque l'on cherche à forcer en rotation l'ensemble constitué par le rotor 10 et le stator intermédiaire 12 solidarisés en rotation, la saillie 48 de l'organe d'indexation 32 échappe hors de la rainure longitudinale 58 et le talon 60 vient simultanément pénétrer dans l'encoche 64 formée dans le rotor 10, ainsi que cela est illustré en trait mixte à la figure 3 et en trait plein à la figure 4. Cette coopération du talon 60 avec l'encoche 64 permet de renforcer la solidarisation en rotation du rotor 10 avec le stator intermédiaire 12. C'est donc l'ensemble constitué par le rotor 10 et le stator intermédiaire 12 qui tourillonne dans le corps 14 empêchant tout actionnement du mécanisme de serrure.When one seeks to force in rotation the assembly formed by the rotor 10 and the intermediate stator 12 secured in rotation, the projection 48 of the indexing member 32 escapes from the longitudinal groove 58 and the heel 60 simultaneously comes into the notch 64 formed in the rotor 10, as shown in phantom in Figure 3 and in solid line to FIG. 4. This cooperation of the heel 60 with the notch 64 makes it possible to reinforce the rotational connection of the rotor 10 with the intermediate stator 12. It is therefore the assembly formed by the rotor 10 and the intermediate stator 12 which pivots in the body 14 preventing any actuation of the lock mechanism.

On appréciera que l'organe d'indexation 32 réalisé conformément aux enseignements de l'invention est de conception particulièrement simple dans la mesure ou il s'agit d'une pièce unique moulée en matière plastique qui est mise en position, lors de l'assemblage du verrou, en mettant en place son extrémité 36, 44 dans l'évidement 38 et le trou 46, sans qu'aucune opération supplémentaire de montage d'un ressort de rappel ne soit nécessaire.It will be appreciated that the indexing member 32 produced in accordance with the teachings of the invention is of particularly simple design insofar as it is a single piece molded from plastic material which is placed in position during the assembly of the lock, by putting its end 36, 44 in the recess 38 and the hole 46, without any additional operation for mounting a return spring being necessary.

On décrira maintenant le second mode de réalisation illustré aux figures 6 à 10.We will now describe the second embodiment illustrated in FIGS. 6 to 10.

Ce second mode de réalisation se distingue essentiellement du mode de réalisation précédent en ce que la poutre d'indexation 32 n'est pas encastrée au voisinage de sa première extrémité longitudinale 36 mais est réalisée sous la forme d'une poutre simple en appui à ses deux extrémités opposées.This second embodiment differs essentially from the previous embodiment in that the indexing beam 32 is not embedded in the vicinity of its first longitudinal end 36 but is produced in the form of a simple beam resting on its two opposite ends.

A cet effet, l'extrémité 36 de gauche du corps 34 de la poutre 32, en considérant la figure 7, est en appui contre un fond en vis-à-vis 39 du logement 33, tandis que l'extrémité 41 de droite du corps 34 de la poutre 32 est en appui contre une portion de fond correspondante 43 du logement 33.To this end, the left end 36 of the body 34 of the beam 32, considering FIG. 7, is pressed against a bottom facing 39 of the housing 33, while the right end 41 of the body 34 of beam 32 is pressing against a corresponding bottom portion 43 of the housing 33.

Les portions de fond 39 et 43 sont délimitées longitudinalement par la fenêtre 62 formée dans le fond du logement 33.The bottom portions 39 and 43 are delimited longitudinally by the window 62 formed in the bottom of the housing 33.

La face radiale externe 42 de l'extrémité de gauche 36 de la poutre, qui est continue le long du corps 34 de la poutre, est en contact avec la paroi périphérique interne 15 du corps fixe 14 du verrou.The external radial face 42 of the left end 36 of the beam, which is continuous along the body 34 of the beam, is in contact with the internal peripheral wall 15 of the fixed body 14 of the latch.

L'extrémité 36 est ainsi maintenue radialement dans les deux sens.The end 36 is thus held radially in both directions.

La poutre d'indexation 32 illustrée aux figures 6 à 10 est donc ainsi susceptible de se déformer élastiquement dans sa partie centrale.The indexing beam 32 illustrated in FIGS. 6 to 10 is therefore thus liable to deform elastically in its central part.

La saillie 48 et le talon 60 sont tous deux agencés dans la partie centrale de la poutre d'indexation 32, c'est-à-dire dans la partie susceptible de se déformer élastiquement entre les appuis d'extrémité opposés.The projection 48 and the heel 60 are both arranged in the central part of the indexing beam 32, that is to say in the part liable to deform elastically between the opposite end supports.

Le fonctionnement de ce second mode de réalisation est en tous points identiques à celui qui a été décrit en référence aux figures 1 à 5.The operation of this second embodiment is identical in all respects to that which has been described with reference to FIGS. 1 to 5.

A titre de variante, et sans sortir du cadre de l'invention, il est possible de réaliser la poutre d'indexation venue de matière par moulage avec le stator intermédiaire.Alternatively, and without departing from the scope of the invention, it is possible to produce the indexing beam made of material by molding with the intermediate stator.
