d'un véhicule automobile.of a motor vehicle.
De telles serrures sont constituées globalement d'un barillet cylindrique tourillonnant dans un alésage d'un corps, ledit barillet étant solidaire d'une came Such locks generally consist of a cylindrical barrel journalling in a bore of a body, said barrel being integral with a cam
d'entraînement d'un pêne.bolt drive.
La serrure étant assemblée est introduite dans un support, tel un manchon de verrou et doit être verrouillée par rapport à ce support en translation et en rotation. Néanmoins une telle serrure présente des moyens permettant son extraction du support pour la réparation ou l'entretien, c'est-à-dire sans destruction de ladite serrure. Le verrouillage de la serrure dans son support s'effectue lors de son assemblage sur les chaînes de montage du véhicule: il est donc nécessaire que le dispositif de verrouillage dont elle est équipée fasse partie intégrante de la serrure et ne nécessite aucun The lock being assembled is introduced into a support, such as a lock sleeve and must be locked relative to this support in translation and in rotation. However, such a lock has means allowing its extraction from the support for repair or maintenance, that is to say without destroying said lock. The lock is locked in its support during assembly on the vehicle assembly lines: it is therefore necessary that the locking device with which it is fitted is an integral part of the lock and does not require any
outillage particulier pour sa mise en oeuvre. special tools for its implementation.
Les moyens habituels utilisés sont constitués de goupilles ou de circlips, voire de systèmes vis-écrou ce qui entraîne des opérations de montage relativement The usual means used consist of pins or circlips, or even screw-nut systems, which results in relatively assembly operations.
complexes et difficilement automatisables. complex and difficult to automate.
De plus, l'assemblage d'un tel verrou présente en général un jeu axial résultant des tolérances de fabrication des différents constituants, jeu axial pouvant entraîner des phénomènes de bruit résultant des In addition, the assembly of such a lock generally has an axial clearance resulting from the manufacturing tolerances of the various constituents, axial clearance which can cause noise phenomena resulting from
vibrations auxquelles est soumis le véhicule. vibrations to which the vehicle is subjected.
La suppression du bruit entraîne l'adjonction de pièces supplémentaires, ce qui augmente inévitablement le coût d'un tel ensemble de manière incompatible avec une fabrication en grande série comme c'est le cas en The suppression of noise leads to the addition of additional parts, which inevitably increases the cost of such an assembly in a manner incompatible with mass production as is the case in
particulier dans le domaine de l'automobile. particularly in the automotive field.

Sur la figure 1, on a représenté une serrure 10 immobilisée en translation et en rotation dans un support In Figure 1, there is shown a lock 10 immobilized in translation and in rotation in a support
12, par un organe de verrouillage 14. 12, by a locking member 14.
Bien entendu la serrure 10 comprend à l'intérieur du corps, stator, rotor et organes de verrouillage tels que pistons ou paillettes Tous ces éléments ne faisant pas partie de la présente invention n'ont pas été Of course the lock 10 comprises inside the body, stator, rotor and locking members such as pistons or flakes All these elements not forming part of the present invention have not been
représentés et ne seront donc pas décrits plus en détail. shown and will therefore not be described in more detail.
La partie avant 16 de la serrure 10 présente globalement une forme cylindrique venant en appui contre un épaulement 18 du support 12 et se prolonge par un fût venant se loger dans un alésage 21 du support 12 de plus petit diamètre à l'intérieur duquel est ménagée une rainure radiale 22 destinée au logement de l'organe de The front part 16 of the lock 10 generally has a cylindrical shape coming to bear against a shoulder 18 of the support 12 and is extended by a barrel which is housed in a bore 21 of the support 12 of smaller diameter inside which is provided a radial groove 22 intended for housing the member for
verrouillage 14.lock 14.
En regard de la rainure radiale 22, le support 12 comprend des passages radiaux 24 dont le rôle sera Opposite the radial groove 22, the support 12 includes radial passages 24 whose role will be
explicité plus avant.explained further.
Ainsi qu'on peut le voir plus en détail sur les figures 2 à 5, l'organe de verrouillage 14 est constitué globalement de deux blocs 26, dits blocs de verrouillage, As can be seen in more detail in FIGS. 2 to 5, the locking member 14 is generally made up of two blocks 26, called locking blocks,
à écartement variable, symétriques par rapport à l'axe X- with variable spacing, symmetrical with respect to the X- axis
X de la serrure, les deux blocs 26 étant reliés par des X of the lock, the two blocks 26 being connected by
moyens élastiques 28,29.elastic means 28.29.
Chacun des blocs 26, de forme générale parallélépipèdique, présente un évidement 30 à l'intérieur duquel est agencée de matière une tige radiale 32 dont l'extrémité présente un renflement 34 formant saillie par rapport à la face avant 36 des blocs 26. La face extérieure de chaque bloc est chanfreinée de manière à constituer une face inclinée 38 par rapport Each of the blocks 26, of generally parallelepipedal shape, has a recess 30 inside which is arranged in material a radial rod 32 whose end has a bulge 34 projecting from the front face 36 of the blocks 26. The face outside of each block is chamfered so as to constitute an inclined face 38 relative to
à l'axe général X-X de la serrure. to the general axis X-X of the lock.
Les moyens élastiques 28,29 se présentent sous forme de pattes 28,29 reliant les deux blocs 26 par leurs faces horizontales intérieures 40 L'une des pattes 28 est située vers la face avant 36 des blocs 26 tandis que l'autre patte 29 est située vers la face arrière 42 The elastic means 28, 29 are in the form of lugs 28, 29 connecting the two blocks 26 by their internal horizontal faces 40 One of the lugs 28 is located towards the front face 36 of the blocks 26 while the other lug 29 is located towards the rear 42
desdits blocs 26.of said blocks 26.
Chacune des pattes 28,29 est globalement inclinée par rapport à l'axe vertical Y-Y du dispositif de verrouillage 14 et présente, entre leurs points d'attache Each of the tabs 28, 29 is generally inclined relative to the vertical axis Y-Y of the locking device 14 and has, between their attachment points
aux faces intérieures 40, une double inflexion. on the inner faces 40, a double inflection.
Ainsi qu'on peut le voir sur la figure 2, les pattes 28,29 ont, par rapport à l'axe vertical Y-Y, des As can be seen in FIG. 2, the tabs 28, 29 have, with respect to the vertical axis Y-Y,
inclinaisons opposées.opposite inclinations.
De cette manière chacune des pattes 28,29 relie l'un des bords verticaux d'un des blocs 26, au bord In this way each of the legs 28, 29 connects one of the vertical edges of one of the blocks 26, to the edge
vertical naturellement opposé de l'autre bloc 26. vertical naturally opposite from the other block 26.
Le fonctionnement d'un tel dispositif est le suivant. L'organe de verrouillage 14, obtenu par moulage en matière plastique, est introduit dans la rainure radiale 22 de la serrure 10 et y est maintenu par simple serrage des faces avant 36 et arrière 42 des blocs 26 The operation of such a device is as follows. The locking member 14, obtained by plastic molding, is introduced into the radial groove 22 of the lock 10 and is held there by simple tightening of the front 36 and rear 42 faces of the blocks 26
contre les parois de ladite rainure 22. against the walls of said groove 22.
La serrure 10 ainsi équipée est introduite dans son support 12, suivant un mouvement axial de la droite The lock 10 thus equipped is introduced into its support 12, following an axial movement from the right
vers la gauche dans l'exemple représenté figure 1. to the left in the example shown in Figure 1.
Lors du déplacement de la serrure 10, les faces inclinées 38 des blocs 26 viennent en appui sur l'épaulement 18 du support 12 Grâce à l'élasticité des pattes 28,29, les blocs 26 se déplacent l'un vers l'autre radialement ce qui permet à l'organe de verrouillage 14 During the movement of the lock 10, the inclined faces 38 of the blocks 26 come to bear on the shoulder 18 of the support 12 Thanks to the elasticity of the tabs 28, 29, the blocks 26 move towards each other radially which allows the locking member 14
de franchir l'alésage 21.to cross bore 21.
Ce franchissement réalisé, les blocs 26, toujours sous l'effet des pattes élastiques 28,29, opèrent un mouvement radial inverse au précédent et viennent se loger dans les passages radiaux 24 du support 12, immobilisant ainsi en rotation et en translation This crossing achieved, the blocks 26, still under the effect of the elastic tabs 28, 29, operate a radial movement opposite to the previous one and are housed in the radial passages 24 of the support 12, thus immobilizing in rotation and in translation
l'ensemble de la serrure 10 dans son support 12. the whole of the lock 10 in its support 12.
Les renflements 34 des tiges 32 viennent en appui élastique contre l'une des parois verticales des passages 24 et constituent ainsi un moyen de rattrapage de jeu axial, moyen qui permet en même temps d'éliminer des phénomènes de bruit dus en particulier aux vibrations du The bulges 34 of the rods 32 come into resilient abutment against one of the vertical walls of the passages 24 and thus constitute a means of compensating for axial play, means which at the same time makes it possible to eliminate noise phenomena due in particular to the vibrations of the
véhicule sur lequel un tel dispositif est monté. vehicle on which such a device is mounted.
Autrement dit, les évidements 30, les tiges radiales 32 et les renflements 34 constituent des moyens de guidage pour l'écartement ou le rapprochement desdits In other words, the recesses 30, the radial rods 32 and the bulges 34 constitute guide means for the spacing or bringing together of said
blocs de verrouillage 26.locking blocks 26.
Bien entendu la présente invention ne se limite pas aux formes de réalisation décrites ou représentées mais englobe toute variante que l'homme de l'art pourrait Of course, the present invention is not limited to the embodiments described or shown but encompasses any variant that a person skilled in the art could
y apporter.bring it.
