L'ouvrant de véhicule peut être une porte avant, une porte arrière, ou encore un volet de coffre ou de hayon.The vehicle opening can be a front door, a rear door, or a tailgate or tailgate.

Avant de réaliser la fixation des gâches des portes avant et arrière sur la caisse d'un véhicule automobile, il est connu de fixer rigidement par soudage sur les pièces de renfort des portes des cages de type dit « cage romaine », par soudage de préférence. Une cage romaine est composée d'une plaque plane ou cage proprement dite, sur laquelle vient se placer une autre plaque dite « romaine », fixée à la gâche et présentant deux degrés de liberté en translation avec la cage pour le pilotage et le positionnement précis de la gâche.Before making the fastening of the doors of the front and rear doors on the body of a motor vehicle, it is known to fix rigidly by welding on the reinforcements of the doors of the type of cage called "Roman cage" by welding preferably . A Roman cage consists of a flat plate or cage proper, on which is placed another plate called "Roman", attached to the striker and having two degrees of freedom in translation with the cage for control and precise positioning of the waste.

On a déjà cherché à simplifier la fixation des systèmes de fermeture des ouvrants de véhicules.It has already been sought to simplify the fixing of closing systems of the opening of vehicles.

Ainsi, le document DE 44 01 071 C1 décrit un dispositif de fixation d'un verrou de blocage sur une caisse de véhicule automobile, par exemple sur un panneau de carrosserie d'un montant de porte latérale. La fixation se fait au moyen d'une liaison par vis. Une plaque, équipée d'un filetage d'écrou et pouvant être connectée au verrou de blocage, est disposée sur l'intérieur du panneau de carrosserie et peut être liée à ce dernier, de façon à permettre un mouvement d'ajustement du positionnement. Pour que ce mouvement puisse être exécuté de manière relativement simple et pour que le verrou de blocage puisse être positionné de telle manière que soit garanti un fonctionnement optimal du verrouillage, le panneau de carrosserie présente des jeux ou espacements, dans lesquels peuvent venir s'insérer des parties en extension de la plaque, découpées suivant un contour bien adapté. Après insertion, ces parties en extension peuvent être reliées au panneau de carrosserie par le moyen d'un simple mouvement de déplacement.Thus, the document DE 44 01 071 C1 discloses a device for fixing a locking lock on a motor vehicle body, for example on a body panel of a side door jamb. Fixing is done by means of a screw connection. A plate, equipped with a nut thread and connectable to the locking latch, is disposed on the inside of the body panel and can be connected thereto, so as to allow movement positioning adjustment. So that this movement can be executed in a relatively simple manner and so that the locking lock can be positioned in such a way that is guaranteed optimal operation of the lock, the body panel has games or spacings, in which can be inserted parts in extension of the plate, cut in a well adapted contour. After insertion, these extended parts can be connected to the body panel by means of a simple movement movement.

The reinforcement 11 is welded to the rear foot 10 by means of weld points 12 at the rabbet. The Roman cage 20, 30 is fixed on the face of the reinforcement 11 opposite to that on which is fixed the striker.

La présente invention porte essentiellement sur la configuration de la cage 20 de la cage romaine, la romaine 30 étant mise en place sur la cage 20 et retenue par les pattes de fixation désignées 25 de la cage 20.The present invention relates essentially to the configuration of the cage 20 of the Roman cage, the Roman 30 being placed on the cage 20 and retained by the designated fastening tabs 25 of the cage 20.

En référence à la figure 4, la cage 20 présente, à sa partie inférieure et à sa partie supérieure, un profilé ou contour 21, respectivement 22, permettant de séparer, comme montré sur la figure 5, les zones des points de soudure 26 pour la fixation de la cage 20 sur le renfort 11 des zones des points de soudure 27 pour la fixation du renfort 11 sur la caisse, à savoir le pied arrière du véhicule.With reference to the figure 4 , the cage 20 has, at its lower part and at its upper part, a profile or contour 21, respectively 22, for separating, as shown in FIG. figure 5 , the areas of the weld points 26 for fixing the cage 20 on the reinforcement 11 of the zones of the weld points 27 for the fixing the reinforcement 11 on the body, namely the rear foot of the vehicle.

Comme on peut le voir également sur la figure 5, les zones de fixation par soudure 27 du renfort 11 sur le pied arrière sont sensiblement dans l'axe A des vis de fixation 4 de la gâche sur la romaine 30, de façon à éviter toute contrainte de torsion qui pourrait endommager la caisse du véhicule sous l'action des efforts mécaniques répétés sur la gâche lors de la fermeture de la porte.As can be seen also on the figure 5 , the weld fixing zones 27 of the reinforcement 11 on the rear foot are substantially in the axis A of the fixing screws 4 of the striker on the Roman 30, so as to avoid any torsional stress which could damage the vehicle body under the action of repeated mechanical forces on the striker when closing the door.

Chacun des contours, 21 et 22, de la cage 20 forme une patte en extension, 21A et 22A respectivement, sur laquelle se trouve une zone de fixation par soudure 26 de la cage 20 sur le renfort 11 et un évidemment sensiblement rectangulaire à l'intérieur duquel se trouve la zone de fixation 27 du renfort 11 sur la caisse.Each of the contours 21 and 22 of the cage 20 form an extended tab 21A and 22A, respectively, on which there is a weld fixing zone 26 of the cage 20 on the reinforcement 11 and a recess substantially rectangular to the inside which is the fastening zone 27 of the reinforcement 11 on the body.

Les zones de fixation par soudure 26 de la cage 20 sur le renfort 11 sont situées, selon la même direction (figure 4) du véhicule, entre les zones de fixation 27 du renfort 11 sur la caisse du véhicule et l'habitacle représenté par le côté d'habitacle 14.The weld fixing zones 26 of the cage 20 on the reinforcement 11 are situated in the same direction ( figure 4 ) of the vehicle, between the attachment zones 27 of the reinforcement 11 on the vehicle body and the passenger compartment represented by the cockpit side 14.

On notera qu'avec une cage classique de fixation de gâche, telle que connue de l'art antérieur, il y a trois pièces d'épaisseur relativement importante à souder ensemble, à savoir la cage 20, le renfort de fixation 11 de gâche et un élément de caisse (côté d'habitacle). Il faut alors réaliser un soudage dit « soudage pulse », c'est-à-dire un soudage par pulsations qui nécessite une force de serrage et une puissance électrique relativement plus importante qu'un soudage par points électriques - ou soudage PSE - de type normal ou standard utilisé pour les assemblages dont l'épaisseur de référence est plus faible.It should be noted that with a conventional striker holder, as known from the prior art, there are three pieces of relatively large thickness to be welded together, namely the cage 20, the striker attachment bracket 11 and a body element (cockpit side). It is then necessary to perform a so-called "pulse welding" welding, that is to say a pulse welding which requires a clamping force and a relatively greater electrical power than a welding by electrical points - or PSE welding - type normal or standard used for assemblies with a lower reference thickness.

La forme de la cage de la présente invention permet d'éviter le recours au soudage « pulse » et permet d'utiliser le soudage PSE « standard » aussi bien pour les points de soudure 27 que pour les points de soudure 26.The shape of the cage of the present invention makes it possible to avoid the use of "pulse" welding and makes it possible to use "standard" PSE welding both for soldering points 27 only for soldering points 26.

Par « soudage PSE standard » ou normal, on entend un soudage train continu pour des assemblages dont l'épaisseur de référence est inférieure ou égale à 1,27 mm avec des embouts de fût de 16 mm et 6mm de face active permettant de réaliser des PSE de 4 mm minimum."Standard or standard PSE welding" means continuous welding of welds for assemblies with a reference thickness of 1.27 mm or less with 16 mm and 6 mm shank ends of active face, allowing PSE of 4 mm minimum.

En évitant ainsi le recours au soudage « pulse », on évite le risque de projection de soudure susceptible d'entraîner des retouches sur le côté d'habitacle, et donc des coûts supplémentaires de fabrication.By avoiding the use of "pulse" welding, it avoids the risk of welding projection likely to cause retouching on the passenger side, and therefore additional manufacturing costs.

Comme représenté sur les figures 4 et 5 en particulier, des encoches ou découpes 23, 24 en forme de secteurs circulaires sont prévues sur les bords latéraux de la cage 20. Des découpes de même profil, désignées 33 et 34 sur la figure 5, sont prévues sur les bords latéraux de la romaine 30. Les découpes 33, respectivement 34, de la romaine 30 sont superposées aux découpes 23, respectivement 24, de la cage 20 et à des trous circulaires 18, respectivement 19, dans le renfort de fixation 11 pour la mise en place des extrémités de la partie en U de la gâche et aussi pour le passage d'une gâche provisoire ou « butée de process » utilisée seulement au cours de l'opération de peinture, comme expliqué plus loin dans le présent texte.As shown on figures 4 and 5 in particular, notches or cuts 23, 24 in the form of circular sectors are provided on the lateral edges of the cage 20. Cutouts of the same profile, designated 33 and 34 on the figure 5 are provided on the lateral edges of the Roman 30. The cutouts 33, respectively 34, of the Roman 30 are superimposed on the cutouts 23, respectively 24, of the cage 20 and circular holes 18, respectively 19, in the reinforcement of fixing 11 for the establishment of the ends of the U-shaped part of the striker and also for the passage of a temporary striker or "process stop" used only during the painting operation, as explained later in the present text.

Le diamètre de la découpe 33 de la romaine 30 est supérieur au diamètre de la découpe 23 de la cage 20 et le diamètre de la découpe 34 de la romaine 30 est supérieur au diamètre de la découpe 24 de la cage 20, de manière à permettre le positionnement précis du dispositif de cage romaine, et donc de la gâche.The diameter of the cutout 33 of the Roman 30 is greater than the diameter of the cutout 23 of the cage 20 and the diameter of the cutout 34 of the Roman 30 is greater than the diameter of the cutout 24 of the cage 20, so as to allow the precise positioning of the Roman cage device, and therefore of the striker.

Il est important de noter que les découpes des cages de fixation connues de l'art antérieur ne permettaient pas la mise en place de la cage par rapport au renfort de fixation 11. Par le dimensionnement relatif des découpes 23, 24 de la cage de la présente invention, cette mise en place devient possible.It is important to note that the cutouts of the fixing cages known from the prior art did not allow the establishment of the cage with respect to the fixing reinforcement 11. By relative sizing of the cuts 23, 24 of the cage of the present invention, this implementation becomes possible.

Ces découpes 23, 24, les découpes 33, 34 sur la romaine, ainsi que les trous 18, 19 dans le renfort 11, servent également à la mise en place d'une butée dite « butée de process » utilisée seulement au cours de l'opération de peinture. Ainsi, lorsque le véhicule est en phase de peinture, il faut maintenir les portes avant et arrière ouvertes. A cette fin, on utilise des fausses gâches en plastique, de préférence, appelées « butées de process ».These cuts 23, 24, the cutouts 33, 34 on the Roman, as well as the holes 18, 19 in the reinforcement 11, are also used for the establishment of a stop called "stop process" used only during the painting operation. Thus, when the vehicle is painting, keep the front and rear doors open. For this purpose, false plastic strikes are used, preferably called "process stops".

La forme spécifique de la cage romaine de la présente invention est adaptée de telle façon qu'elle permet d'utiliser quatre butées identiques de type standard.The specific shape of the Roman cage of the present invention is adapted such that it allows the use of four identical standard type stops.

La figure 6 représente le dispositif de fixation d'une gâche de serrure pour une porte avant de véhicule, selon la présente invention. Lorsqu'il s'agit d'une gâche de porte avant, droite ou gauche, la cage romaine 20, 30 n'est pas fixée sur un renfort de fixation de gâche de porte, mais sur un renfort de pied milieu 17 de la caisse du véhicule.The figure 6 represents the device for fixing a lock striker for a vehicle front door, according to the present invention. In the case of a front door strike, right or left, the Roman cage 20, 30 is not fixed on a door strike fixing reinforcement, but on a middle foot reinforcement 17 of the body of the vehicle.

Les figures 7a à 7d illustrent un avantage important de la présente invention. La figure 7a représente schématiquement une cage selon l'art antérieur et la figure 7b une cage avec sa romaine selon l'art antérieur également. La figure 7c représente schématiquement une cage selon la présente invention, tandis que la figure 7d représente cette même cage selon l'invention avec sa romaine. On notera que cette nouvelle cage permet, non seulement de souder dans l'axe A des fixations en points de soudure standard et de bien positionner la cage 20 par rapport au renfort 11, mais aussi elle permet de récupérer la romaine existante dans les « cages romaines » de l'art antérieur (la romaine est identique dans les figures 7b à 7d).The Figures 7a to 7d illustrate an important advantage of the present invention. The figure 7a schematically represents a cage according to the prior art and the figure 7b a cage with its Roman according to the prior art also. The Figure 7c schematically represents a cage according to the present invention, while the figure 7d represents this same cage according to the invention with its Roman. It will be noted that this new cage makes it possible, not only to weld axis A with standard weld point fastenings and to position cage 20 relatively to reinforcement 11, but also to recover the existing Roman in the "cages". "Roman" of the prior art (the Roman is identical in the Figures 7b to 7d ).

On notera aussi que le dispositif de fixation de serrure de gâche, de type cage romaine, selon la présente invention est identique pour les quatre portes d'un véhicule automobile, par conséquent il y a une cage romaine commune pour les quatre portes : avant droite, avant gauche, arrière droite et arrière gauche.It will also be noted that the Roman cage type lock lock fixing device according to the present invention is identical for the four doors of a motor vehicle, therefore there is a common Roman cage for the four doors: right front, left front, right rear and left rear.

Le dispositif de fixation de gâche de serrure pour un ouvrant, selon la présente invention, offre encore de nombreux avantages, parmi lesquels les avantages suivants :

  • il est compatible avec l'exigence de qualité, la cage romaine étant pilotée grâce à des trous plus importants réalisés sur les éléments de renfort, et la cage,
  • la préparation de la cage romaine est simplifiée et son soudage (en PSE standards) également,
  • la butée dite « butée de process » employée seulement pour la peinture n'est pas en interférence avec la cage romaine, grâce à de larges découpes,
  • le dispositif de fixation permet de respecter les prestations relatives au claquage de la porte,
The lock striker attachment device for an opening, according to the present invention, still offers many advantages, among which the following advantages:
  • it is compatible with the requirement of quality, the Roman cage being piloted thanks to larger holes made on the reinforcement elements, and the cage,
  • the preparation of the Roman cage is simplified and its welding (in standard EPS) also,
  • the abutment called "process abutment" used only for painting is not in interference with the Roman cage, thanks to large cuts,
  • the fixing device makes it possible to respect the services relating to the breakdown of the door,

Enfin, les dimensions du dispositif de fixation de gâche de serrure selon la présente invention, en particulier sa largeur, son épaisseur, rendent le dispositif compatible avec l'environnement exigu des pieds centraux et arrière du véhicule.Finally, the dimensions of the lock strike fixing device according to the present invention, in particular its width and its thickness, make the device compatible with the small environment of the central and rear feet of the vehicle.

Bien entendu, la présente invention n'est pas limitée au mode de réalisation décrit et représenté ci-dessus à titre d'exemple ; d'autres modes de réalisation peuvent être conçus par l'homme de métier sans sortir du cadre et de la portée de la présente invention.Of course, the present invention is not limited to the embodiment described and shown above by way of example; other embodiments may be devised by those skilled in the art without departing from the scope and scope of the present invention.
