Abstract
Description
L'invention concerne les organes de rétention pour serrure de véhicule automobile, et plus particulièrement un pêne et un cliquet pour une telle serrure.The invention relates to retention members for a lock. motor vehicle, and more particularly a bolt and a ratchet for such a lock.
Un premier organe de rétention est ainsi formé par le pêne qui est du type à fourche qui équipe usuellement les serrures de porte, de dossier, de hayon et de capot d'un véhicule automobile. Le pêne coopère avec un deuxième organe de rétention constitué par le cliquet.A first retention member is thus formed by the bolt which is of the fork type which usually equips door locks, backrest, tailgate and hood of a motor vehicle. The bolt cooperates with a second retention member constituted by the pawl.
Pour mieux situer l'invention, un pêne classique sera d'abord décrit à l'exemple d'un pêne de serrure de dossier schématiquement illustré aux figures 1 à 3. Les figures 1 et 2 montrent en outre la coopération du pêne avec un cliquet classique et une gâche. Les autres éléments de la serrure ne seront pas décrits en détail puisqu'ils n'entrent pas dans le cadre de la présente invention.To better situate the invention, a conventional bolt will first be describes the example of a file lock bolt schematically illustrated in Figures 1 to 3. Figures 1 and 2 further show the bolt cooperation with a classic ratchet and a strike. Others elements of the lock will not be described in detail since they are not within the scope of the present invention.
Le pêne 1 est constitué par une plaque en acier découpée de
manière à présenter la forme générale d'une fourche. Il est monté
pivotant sur un axe de pivotement porté par le boítier de la serrure, de
manière à pouvoir pivoter entre une position fermée et une position
ouverte de celle-ci.The
La fourche est définie par une échancrure 2 qui dans la position
fermée illustrée à la figure 1 reçoit et retient une gâche reliée à un
élément de carrosserie du véhicule. La gâche est généralement
constituée d'une plaquette métallique en U dont l'une des branches est
fixée sur un élément de carrosserie du véhicule, et d'un pion 3 reliant
l'une à l'autre les extrémités libres des deux branches du U. Seul le
pion de la gâche est illustré sur les figures 1 et 2.The fork is defined by a
Pour la rétention du pion 3 de la gâche, le pêne 1 coopère avec
un cliquet 4 qui est également constitué par une plaque en acier
découpée de manière à former un levier.For the retention of the
Le pêne est verrouillé dans la position fermée (voir figure 1) à
l'aide du cliquet 4 qui est monté pivotant dans le boítier de la serrure,
autour d'une articulation à l'une des extrémités du cliquet. Pour obtenir
ce verrouillage, le pêne est pourvu d'un organe de verrouillage
constitué par une queue 5 reliée à l'extrémité de l'une des branches de
la fourche et s'étendant dans le plan de celle-ci vers l'arrière,
sensiblement perpendiculairement à cette branche. La longueur de la
queue est adaptée pour que le pêne reste toujours en contact avec le
chant du cliquet, aussi bien dans la position ouverte que dans la
position fermée.The bolt is locked in the closed position (see Figure 1) at
using the
Dans la position fermée, un rebord avant 5' de la queue 5 est en
butée dans un cran 6 constituant l'organe de verrouillage du cliquet 4 et
est constamment sollicité vers le cliquet par un ressort de rappel 7
monté coaxialement sur l'axe la du pêne, dont l'une des extrémités
prend appui sur une patte 8 qui fait perpendiculairement saillie du plan
du pêne et l'autre sur le boítier de la serrure. L'ensemble du pêne est
en même temps sollicité par ce ressort de rappel 7 vers la position
ouverte de la serrure, et en plus par la réaction du joint de porte qui en
état fermé se trouve comprimé.In the closed position, a
Le cliquet 4 est également sollicité vers la queue 5 du pêne par
un ressort de rappel 9 monté coaxialement sur l'axe 4a du cliquet dont
l'une des extrémités prend appui contre un pion 10 du cliquet et l'autre
sur le boítier.The
Pour déverrouiller la queue 5 du pêne 1 de sa prise avec le cran
6 du cliquet 4, il suffit de faire pivoter le cliquet vers le bas dans la
figure 1, ce qui est obtenu à l'aide d'un levier (non représenté)
coopérant avec un pion 11 disposé près de l'extrémité libre du cliquet.
La queue sort alors du cran 6 en glissant sur le chant du cliquet et le
pêne 1 est automatiquement pivoté par le ressort de rappel 7 vers la
position ouverte et reste dans cette position pour que le pêne lâche sa
prise autour du pion 3 de la gâche et pour ainsi permettre de rabattre le
dossier. Dans le cas d'un dossier arrière, celui-ci est fréquemment
composé de deux parties présentant une largeur d'environ 2/3 du
dossier respectivement 1/3 de celui-ci, et chacune des deux parties est
pourvue d'une serrure. Parfois, le dossier arrière s'étend pratiquement
sur toute la largeur de l'espace intérieur du véhicule, deux serrures sont
prévues et il faut par conséquent les actionner en même temps pour
libérer le dossier.To unlock the
Pour réduire le bruit lors du manoeuvre de la serrure, le pêne
est généralement surmoulé par une matière plastique qui forme une
gaine 12 autour du pêne, comme cela est illustré sur les figures 1 et 2.
Certaines parties du pêne sont dénudées, en particulier le fond de
l'échancrure et la queue 5 qui coopère avec le cran 6 du cliquet 4, ainsi
qu'une partie 13 à l'avant du pêne pour éviter l'éclatement du
surmoulage en matière plastique du pêne si l'utilisateur referme
violemment la porte ou le hayon ou le dossier lorsque le pêne se trouve
en position fermée. Un tel éclatement serait susceptible d'entraíner des
frottements du pêne sur les éléments adjacents et doit être évité.To reduce noise when operating the lock, the latch bolt
is generally overmolded by a plastic material which forms a
Pour résister aux efforts en cas de choc violent, le pêne et le cliquet sont fabriqués en un matériau résistant tel que l'acier. La figure 3 montre à cet égard un pêne présentant une épaisseur a (voir figure 3) relativement importante pour résister premièrement aux efforts agissant dans le plan longitudinal du pêne et qui sont susceptibles de provoquer sa rupture, et deuxièmement aux efforts latéraux agissant dans un plan transversal et qui par une déformation de la contreplaque sur laquelle est fixé le pêne peuvent provoquer l'échappement du pêne de sa prise avec le cliquet. Ce qui est dit en référence au pêne s'applique également au cliquet qui est fixé à cette même contreplaque.To withstand the forces in the event of a violent impact, the bolt and the pawl are made of a resistant material such as steel. Figure 3 shows in this respect a bolt having a thickness a (see Figure 3) relatively large to withstand firstly the forces acting in the longitudinal plane of the bolt and which are liable to cause it to break, and secondly the lateral forces acting in one plane transverse and which by a deformation of the counterplate on which the bolt is fixed can cause the bolt to escape from its grip with the ratchet. What is said with reference to the bolt also applies to the pawl which is fixed to this same plywood.
A titre indicatif, l'épaisseur a doit être au moins de 5 mm pour que le pêne puisse résister à la rupture, alors qu'elle doit être de 6 mm pour éviter l'échappement par rapport au cliquet sous l'effet d'efforts transversaux. Bien entendu, on est obligé de choisir l'épaisseur la plus grande même si cela entraíne une augmentation du poids. Ces épaisseurs sont du même ordre de grandeur pour le cliquet.As an indication, the thickness a must be at least 5 mm so that the bolt can resist breaking, while it must be 6 mm to avoid escaping relative to the pawl under the effect of forces transverse. Of course, we are forced to choose the largest thickness even if it results in an increase in weight. These thicknesses are of the same order of magnitude for the ratchet.
A cause d'une contrainte imposée par l'outil de coupe, la largeur b (voir figure 3) de la paroi autour du trou d'articulation du pêne sur son axe de pivotement doit être égale au moins à 1,5 x a. Cette valeur de 1,5 fois l'épaisseur matière est une valeur usuelle qui dépend de la géométrie et de la complexité de la pièce.Because of a stress imposed by the cutting tool, the width b (see Figure 3) of the wall around the bolt's articulation hole on its pivot axis must be at least 1.5 x a . This value of 1.5 times the material thickness is a usual value which depends on the geometry and the complexity of the part.
Par ailleurs, le pêne n'est généralement pas taré en inertie, contrairement au cliquet qui l'est par son ressort. En règle générale, une serrure doit résister aux forces d'inertie suivantes :
- 60 G dans le sens longitudinal ;
- 60 G dans le sens transversal ;
- 60 G dans le sens vertical.
- 60 G in the longitudinal direction;
- 60 G in the transverse direction;
- 60 G vertically.
Pour fabriquer un pêne ou un cliquet présentant une épaisseur de l'ordre de 6 mm, il est indispensable d'avoir recours à une découpe en plusieurs passes avec des poinçons différents. Cela nécessite une machine-outil importante et complexe et il y a en plus un risque de mauvaise continuité dans les lignes de coupe, ce qui crée des saillies sur lesquelles le cliquet peut s'accrocher au pêne. Il est pour cette raison important de contrôler chaque pièce et de la rectifier si besoin en est, ce qui entraíne des opérations supplémentaires.To make a bolt or ratchet with a thickness of the order of 6 mm, it is essential to use a cutout in several passes with different punches. This requires a large and complex machine tool and there is also a risk of poor continuity in the cutting lines, which creates protrusions on which the pawl can hang on the bolt. It is for this important reason to check each part and correct it if necessary is, which results in additional operations.
Le but de l'invention est de proposer un organe de rétention moins onéreux à la fabrication et qui ne présente pas les défauts mentionnés ci-dessus.The object of the invention is to propose a retention device less expensive to manufacture and without defects mentioned above.

Dans la description qui suit, des éléments analogues à ceux déjà décrits en référence aux figures 1 à 3 porteront les même signes de référence. L'invention sera d'abord décrite en détail à l'exemple de la constitution d'un pêne, alors que le même principe s'applique également au cliquet. Cependant, pour éviter les répétitions, les variantes ne seront décrites qu'en référence au pêne.In the description which follows, elements similar to those already described with reference to Figures 1 to 3 will bear the same signs of reference. The invention will first be described in detail using the example of the constitution of a bolt, while the same principle applies also on ratchet. However, to avoid repetition, variants will only be described with reference to the bolt.
La figure 4 montre un organe de rétention selon l'invention sous
forme d'un pêne dont l'épaisseur a est obtenue par deux éléments
d'organe de rétention sous forme d'éléments de pêne 1A et 1B
présentant un profil identique et une forme identique, ces éléments de
pêne étant superposés l'un sur l'autre pour former un ensemble 1'
constituant le pêne proprement dit.Figure 4 shows a retention member according to the invention in the form of a bolt whose thickness a is obtained by two elements of retention member in the form of
Les deux éléments de pêne 1A, 1B sont fixés l'un à l'autre de
manière convenable, par exemple par soudage ou collage.The two
La figure 5 montre une variante avantageuse dans laquelle les
deux éléments de pêne 1A, 1B sont reliés l'un à l'autre par un
surmoulage constituant une gaine 12. Ainsi, l'opération de
solidarisation par soudage ou collage peut grâce à cet agencement être
supprimée puisque la gaine suffit à elle seule pour relier les deux
éléments ensemble d'une manière très ferme.FIG. 5 shows an advantageous variant in which the
two
Le pêne présente dans ce dernier cas des parties dénudées aux
mêmes endroits (2, 5, 13) que le pêne classique décrit en référence aux
figures 1 et 2. La gaine est également pourvue d'une patte d'appui 8
pour un ressort de rappel (non représenté dans la figure). La gaine 12
comporte également quatre encoches 12a au niveau du trou de passage
de l'axe de pivotement du pêne, pour le centrage dans le moule, par
quatre ergots complémentaires.The bolt presents in the latter case bare parts to the
same places (2, 5, 13) as the classic bolt described with reference to
Figures 1 and 2. The sheath is also provided with a
Les éléments de pêne 1A, 1B permettant d'obtenir ensemble
l'épaisseur optimale a, sont de préférence au nombre de deux, mais
peuvent bien entendu comporter trois, voire plus d'éléments qui dans
ce cas constituent un pêne stratifié.The
Les figures 6 et 7 montrent un autre mode de réalisation de
l'invention dans lequel des moyens d'écartement sont disposés entre
deux éléments de pêne juxtaposés 1A, 1B.Figures 6 and 7 show another embodiment of
the invention in which spacing means are arranged between
two
Dans l'exemple illustré, ces moyens d'écartement sont
constitués par des bossages 14 régulièrement disposés sur l'une des
grandes faces de l'élément de pêne 1A. Lors de l'assemblage, ces
bossages 14 sont dirigées vers l'autre élément de pêne juxtaposé 1B de
sorte qu'un interstice 15 soit créé entre ces deux éléments. Dans le cas
où l'épaisseur totale a, hors gaine, correspond par exemple à 6 mm,
l'interstice peut présenter une épaisseur d'environ 1 mm.In the example illustrated, these spacing means consist of
Dans le cas où le pêne est composé de plus de trois éléments de pêne, deux éléments de pêne pourvu de bossages comme illustré aux figures 6 et 7 peuvent être disposé de part et d'autre d'un élément de pêne dépourvu de bossage.In the case where the bolt is composed of more than three elements of bolt, two bolt elements provided with bosses as illustrated in Figures 6 and 7 can be arranged on either side of an element of bolt without boss.
La figure 8 montre les éléments de pêne 1A, 1B de la figure 7
maintenus écartés l'un de l'autre par les bossages et reliés l'un à l'autre
par de la matière surmoulée qui forme une gaine 12 autour des
éléments. De la matière surmoulée remplit également l'interstice 15
entre les deux éléments de pêne de sorte qu'un ensemble de pêne 1'
sans alvéole est obtenu, ce qui est avantageux pour la rigidité de la
pièce.Figure 8 shows the
Ce mode de réalisation est particulièrement avantageux, puisqu'il permet en plus de réduire le poids de l'ensemble du pêne. Par conséquent, il permet l'utilisation d'un ressort de rappel du pêne à dimensions réduites et donc moins cher à la fabrication.This embodiment is particularly advantageous, since it also makes it possible to reduce the weight of the whole bolt. Through therefore, it allows the use of a return spring reduced dimensions and therefore less expensive to manufacture.
Finalement la figure 9 montre un organe de rétention sous
forme d'un cliquet fabriqué de manière analogue à celle illustrée à la
figure 7. Ce cliquet est composé de deux éléments d'organe de
rétention 4A, 4B sous forme d'éléments de cliquet présentant un profil
périphérique sensiblement identique. L'un des éléments de cliquet (4A)
porte sur une de ses faces des moyens d'écartement sous forme de
bossage 14, alors que l'autre élément de cliquet porte sur sa face
tournée vers l'extérieur un pion 10 et un axe 11.Finally Figure 9 shows a retention device under
shape of a ratchet made in a similar way to that illustrated in the
figure 7. This ratchet is composed of two elements of the
Comme dans l'exemple du pêne, ces éléments de cliquet 4A, 4B
peuvent être reliés ensemble par un enrobage, par soudage ou par
collage.As in the example of the bolt, these
Grâce au fait que l'épaisseur a des organes de rétention est
composée par les épaisseurs de chaque élément d'organe de rétention
1A, 1B, respectivement 4A, 4B et éventuellement un interstice entre
deux éléments juxtaposés, l'invention permet la fabrication de chaque
élément d'organe de rétention en une seule opération de découpe. Due to the fact that the thickness of the retaining members is made up by the thicknesses of each
Ainsi, on n'a plus besoin d'une machine-outil complexe pourvue de plusieurs poinçons différents et le prix de revient des pênes selon l'invention se trouve fortement réduit. Le mode de réalisation le plus avantageux est bien entendu celui comprenant un surmoulage, ce qui fait qu'aucune opération d'assemblage proprement dite n'est nécessaire.So you no longer need a complex machine tool provided with several different punches and the cost price of the bolts according to the invention is greatly reduced. The embodiment the more advantageous is of course that comprising an overmolding, this which means that no assembly operation proper is necessary.
Le coût de fabrication .de toute serrure de véhicule automobile comprenant un organe de rétention selon l'invention est également réduit.The manufacturing cost of any motor vehicle lock comprising a retention member according to the invention is also reduced.
