Description
La présente invention concerne un dispositif de maintien pour une rondelle en matière plastique interposée entre deux pièces dont l'une est en tôle. The present invention relates to a holding device for a plastic washer interposed between two parts, one of which is made of sheet metal.
Un tel dispositif trouve application en particulier à des rondelles en matière plastique percées formant entretoise entre deux tôles, l'une formant écran thermique et l'autre formant support solidaire de la caisse d'un véhicule automobile. Such a device finds application in particular to drilled plastic washers forming a spacer between two sheets, one forming a heat shield and the other forming a support integral with the body of a motor vehicle.
Lors du montage de la tôle formant écran thermique sur la tôle de support fixe, il faut mettre en lieu et place un certain nombre de rondelles d'isolation en matière plastique afin d'éviter une conductibilité thermique de la tôle formant écran avec la caisse du véhicule à laquelle est fixée la tôle de support. When mounting the sheet metal forming a heat shield on the fixed support sheet, a certain number of plastic insulating washers must be replaced instead of thermal conductivity of the sheet metal forming the screen with the body of the vehicle to which the support plate is attached.
A cet effet, diverses solutions ont été proposées jusqu'à maintenant. To this end, various solutions have been proposed so far.
L'une de ces solutions consiste à maintenir chacune de ces rondelles par collage (point de colle) ou par adjonction d'un film autocollant à double face. One of these solutions consists in maintaining each of these washers by gluing (point of glue) or by adding a double-sided adhesive film.
Cette solution est relativement coûteuse et le film autocollant, en contact direct avec la tôle, peut brûler. This solution is relatively expensive and the self-adhesive film, in direct contact with the sheet, can burn.
Une autre solution consiste à maintenir la rondelle à la tôle correspondante par une autre pièce en forme de cage. Another solution is to hold the washer to the corresponding sheet by another piece in the form of a cage.
Cependant, cette solution, en plus d'être également coûteuse, est gênante ou encombrante de par la présence de la cage de maintien de la rondelle. However, this solution, in addition to being also expensive, is bothersome or bulky due to the presence of the washer retaining cage.
La présente invention propose un dispositif de maintien pour une rondelle en matière plastique éliminant les inconvénients ci-dessus des dispositifs connus. The present invention provides a holding device for a plastic washer eliminating the above drawbacks of known devices.
A cet effet, selon l'invention, le dispositif de maintien pour une rondelle en matière plastique interposée entre deux pièces dont l'une est en tôle, est caractérisé en ce qu'il comprend au moins deux languettes de maintien de la rondelle relativement à la pièce en tôle et découpées dans la pièce en tôle avec leurs extrémités coopérant avec le contour de la rondelle. To this end, according to the invention, the holding device for a plastic washer interposed between two parts, one of which is made of sheet metal, is characterized in that it comprises at least two tabs for holding the washer relative to the sheet metal part and cut from the sheet metal part with their ends cooperating with the contour of the washer.
Avantageusement, l'extrémité des languettes de maintien est écartée du plan de contact entre la rondelle et la pièce en tôle et la portion extrême des languettes est inclinée vers ce plan en s'approchant de son extrémité. Advantageously, the end of the retaining tongues is spaced from the contact plane between the washer and the sheet metal part and the end portion of the tongues is inclined towards this plane while approaching its end.
Selon un mode de réalisation, le plan de contact précité est constitué, sur la pièce en tôle, par le fond plat d'un embouti de même largeur que la rondelle. According to one embodiment, the abovementioned contact plane is formed, on the sheet metal part, by the flat bottom of a stamped of the same width as the washer.
Avantageusement, la profondeur de l'embouti est suffisante pour que les languettes de maintien soient sur toute leur longueur inclinées vers le plan de contact sans désaffleurer de la face avoisinante de la pièce en tôle. Advantageously, the depth of the stamp is sufficient for the holding tabs to be inclined over their entire length towards the contact plane without flush with the neighboring face of the sheet metal part.
L'invention vise également l'application du dispositif de maintien défini ci-dessus à une rondelle en matière plastique percée formant entretoise entre deux tôles, telles qu'une tôle formant écran thermique et une tôle de support solidaire de la caisse d'un véhicule automobile, et recevant un rivet de fixation de la tôle munie de la rondelle à l'autre tôle. The invention also relates to the application of the holding device defined above to a plastic washer pierced forming a spacer between two sheets, such as a sheet forming a heat shield and a support sheet integral with the body of a vehicle. automobile, and receiving a rivet for fixing the sheet fitted with the washer to the other sheet.
L'invention sera mieux comprise et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant deux modes de réalisation de l'invention et dans lesquels:
- la figure 1 est une vue de face d'un premier mode de réalisation du dispositif de maintien d'une rondelle conforme à l'invention,
- la figure 2 est une vue en coupe suivant la ligne II-II de la figure 1,
- la figure 3 est une vue de face du second mode de réalisation du dispositif de maintien d'une rondelle conforme à l'invention; et
- la figure 4 est une vue en coupe suivant la ligne IV-IV de la figure 3.The invention will be better understood and other objects, characteristics, details and advantages thereof will appear more clearly during the explanatory description which follows, made with reference to the appended schematic drawings given solely by way of example illustrating two modes. of the invention and in which:
FIG. 1 is a front view of a first embodiment of the device for holding a washer according to the invention,
FIG. 2 is a sectional view along the line II-II of FIG. 1,
- Figure 3 is a front view of the second embodiment of the device for holding a washer according to the invention; and
- Figure 4 is a sectional view along line IV-IV of Figure 3.
L'invention va être décrite en application au maintien d'une rondelle en matière plastique formant entretoise entre deux tôles, une tôle formant écran thermique et une tôle de support solidaire de la caisse d'un véhicule automobile, mais il est bien entendu qu'elle n'est pas limitée uniquement à une telle application. The invention will be described in application to the maintenance of a plastic washer forming a spacer between two sheets, a sheet forming a heat shield and a support sheet integral with the body of a motor vehicle, but it is understood that it is not limited only to such an application.
En se reportant aux figures 1 et 2, le dispositif de maintien d'une rondelle en matière plastique 1 interposée entre une tôle formant écran thermique 2 et une tôle de support 3 solidaire de la caisse (non représentée) d'un véhicule automobile, comprend un certain nombre de languettes 4 de maintien de la rondelle 1 relativement à la tôle 2 et découpées dans cette dernière avec leur extrémité 4a coopérant avec le contour de la rondelle 1. Dans le cas présent, les languettes de maintien 4 sont au nombre de six, deux à deux diamétralement opposées, mais il est bien entendu qu'on peut prévoir un nombre différent de languettes pourvu qu'il y en ait au moins deux pour assurer le maintien de la rondelle 1. Referring to Figures 1 and 2, the device for holding a plastic washer 1 interposed between a sheet forming a heat shield 2 and a support sheet 3 secured to the body (not shown) of a motor vehicle, comprises a certain number of tongues 4 for holding the washer 1 relative to the sheet 2 and cut therefrom with their end 4a cooperating with the contour of the washer 1. In the present case, there are six retaining tongues 4 , two to two diametrically opposite, but it is understood that one can provide a different number of tongues provided that there are at least two to ensure the maintenance of the washer 1.
Comme cela ressort de la figure 2, l'extrémité 4a des languettes de maintien 4 est écartée du plan de contact P entre la rondelle 1 et la tôle 2 et la portion extrême 4b des languettes 4 est inclinée vers ce plan en s'approchant de son extrémité. L'extrémité 4a des languettes 4 s'engage légèrement dans la rondelle 1 par déformation élastique de cette dernière. As can be seen from FIG. 2, the end 4a of the retaining tongues 4 is moved away from the contact plane P between the washer 1 and the sheet 2 and the end portion 4b of the tongues 4 is inclined towards this plane while approaching its end. The end 4a of the tongues 4 engages slightly in the washer 1 by elastic deformation of the latter.
Le plan de contact P est constitué, sur la tôle 2, par le fond plat d'un embouti 5 sensiblement de même largeur que la rondelle 1. De plus, la profondeur de l'embouti 5 est suffisante pour que les languettes de maintien 4 soient sur toute leur longueur inclinées vers le plan de contact P sans désaffleurer de la face avoisinante F de la tôle 2. The contact plane P is formed, on the sheet 2, by the flat bottom of a stamped 5 substantially the same width as the washer 1. In addition, the depth of the stamped 5 is sufficient for the holding tabs 4 are along their entire length inclined towards the contact plane P without flush with the neighboring face F of the sheet 2.
Une vis ou un rivet en aluminium 6 traversant les tôles 2, 3 et le perçage axial la de la rondelle 1 permet la fixation de l'ensemble tôle 2 et rondelle 1 à la tôle de support 3 avec bien entendu la tôle 2 espacée de la tôle 3 par la rondelle 1. An aluminum screw or rivet 6 passing through the sheets 2, 3 and the axial drilling la of the washer 1 allows the fixing of the sheet 2 and washer 1 assembly to the support sheet 3 with of course the sheet 2 spaced from the sheet 3 by washer 1.
Le dispositif de maintien représenté aux figures 3 et 4 ne diffère de celui des figures 1 et 2 que par l'absence d'embouti formant le plan de contact P et par le nombre de languettes de maintien 4 dans le cas présent au nombre de trois. The holding device shown in Figures 3 and 4 differs from that of Figures 1 and 2 only by the absence of stamped forming the contact plane P and by the number of holding tabs 4 in this case three in number .
Ainsi, selon ce second mode de réalisation, le plan de contact P entre la rondelle 1 et la tôle 2 est tout simplement constitué par la face plane de cette dernière.Thus, according to this second embodiment, the contact plane P between the washer 1 and the sheet 2 is simply constituted by the planar face of the latter.
Mises à part ces différences, le dispositif de maintien de ce second mode de réalisation présente les mêmes caractéristiques que celui du premier mode de réalisation décrit précédemment.Apart from these differences, the holding device of this second embodiment has the same characteristics as that of the first embodiment described above.
Selon le dispositif de maintien conforme à l'invention, où chaque rondelle entretoise est intégrée à la tôle formant écran thermique, le montage de cette dernière à la tôle de support solidaire du châssis d'un véhicule automobile peut être effectué en automatique et, dans le cas d'un montage en manuel, celuici est grandement facilité. According to the holding device according to the invention, where each spacer washer is integrated into the sheet forming a heat shield, the mounting of the latter to the support sheet integral with the chassis of a motor vehicle can be carried out automatically and, in in the case of manual assembly, this is greatly facilitated.
