Abstract

Between the collars 21, 31 of the tubular end-fittings 2 and 3 of the device 10 according to the invention and its spherical hollow body 1, a peripheral groove 8, 9 has been formed, one of the faces of which corresponds to the lateral face 11a, 12a of a bead 11, 12. A stop for supporting the plates 4 and 5 is thus formed opposite each collar 21 and 31.

Description

On sait que Les accessoires des véhicules, et plus particulièrement les lanternes de signalisation, sont soumis à des vibrations sinusoida- les importantes, principalement lorsqu'iL s'agit de véhicules tous terrains équipés surtout de moteurs Diesel. Les vibrations sinusoidales mesurées sur véhicule entre 5 et 500 HZ conduisent à des fréquences de résonnance susceptibles de se produire suivant les trois axes traditionnels = verticaL-longitudinal-transversal.  It is known that vehicle accessories, and more particularly signaling lanterns, are subject to significant sinusoidal vibrations, mainly when they are all-terrain vehicles mainly equipped with diesel engines. The sinusoidal vibrations measured on vehicles between 5 and 500 HZ lead to resonance frequencies likely to occur along the three traditional axes = verticaL-longitudinal-transverse.

Ces fréquences de résonnance peuvent facilement atteindre 160 à 200 HZ et détruire les filaments des lampes montées dans les lanternes de signalisation. These resonant frequencies can easily reach 160 to 200 HZ and destroy the filaments of the lamps mounted in the signaling lanterns.

On utilise pour contrecarrer ce phénomène, un ensemble d'amortisseurs permettant d'absorber les vibrations dans les trois axes traditionnels = vertical-longitudinal-transversal et d'obtenir un déplacement très réduit de la position du filament des lampes quand on se trouve en présence de résonance. To counteract this phenomenon, a set of shock absorbers is used to absorb vibrations in the three traditional axes = vertical-longitudinal-transverse and to obtain a very reduced displacement of the position of the filament of the lamps when one is in the presence of resonance.

Les dispositifs amortisseurs sont chacun réalisés au moyen d'un corps creux grossièrerement sphérique prolongé par deux embouts tubulaires axiaux à collerette propres å s'engager d'une part dans l'une des perforations d'une plaque fixée à l'embase de l'appareil et d'autre part dans l'une des ouvertures de la plaque portant par exemple une ampoule. The damping devices are each produced by means of a roughly spherical hollow body extended by two axial tubular ends with a collar suitable for engaging on the one hand in one of the perforations of a plate fixed to the base of the device and on the other hand in one of the openings of the plate carrying for example a bulb.

L'inconvénient principal de tels dispositifs est que sous l'influence des vibrations, il se produit une espèce de fluage de la matière élastique constituant lesdits corps creux et qui se trouve en l'occurence etre du caoutchouc synthétique ou naturel, de telle sorte que ledit corps se déplace plus ou moins de manière définitive, soit dans la perforation de 'la plaque porte-ampoule,soit dans l'ouverture de l'accessoire
Lui-même. Ainsi, Le filament de l'ampoule n'est plus disposé exactement dans l'axe des gravures du couvercle du feu de signalisation, de telle sorte que l'écLairage produit est défectueux et n'est plus conforme au code de la route.
The main drawback of such devices is that under the influence of vibrations, there occurs a kind of creep of the elastic material constituting said hollow bodies and which is in this case being synthetic or natural rubber, so that said body moves more or less permanently, either in the perforation of the bulb holder plate, or in the opening of the accessory
Himself. Thus, the filament of the bulb is no longer placed exactly in the axis of the engravings of the cover of the traffic light, so that the lighting produced is defective and no longer complies with the highway code.

Les perfectionnements qui font L'objet de la présente invention visent à remédier à ces inconvénients et à permettre de réaliser un dispositif amortisseur insensible aux vibrations sinusoidales et conservant sa position initiale avec une grande précision quelles que soient les vibrations suivant les trois axes traditionnels. The improvements which are the object of the present invention aim to remedy these drawbacks and to make it possible to produce a damping device insensitive to sinusoidal vibrations and retaining its initial position with great precision whatever the vibrations along the three traditional axes.

A cet effet, le dispositif amortisseur suivant l'invention comporte une gorge périphérique de part et d'autre du corps au niveau des liaisons avec Les embouts, la largeur de cette gorge correspondant à
L'épaisseur de la plaque qui y est engagée.
To this end, the damping device according to the invention comprises a peripheral groove on either side of the body at the connections with the end pieces, the width of this groove corresponding to
The thickness of the plate which is engaged there.

Dans un mode d'exécution préféré de l'invention, la jonction de la gorge et du corps central du dispositif comporte un cordon formant avec
la face latérale correspondante de la gorge une butée d'appui pour
l'élément plan engagé dans cette gorge, et qui bute en outre contre la collerette correspondante de l'embout ; de ce fait la cote de montage entre les deux gorges est très précise et permet de positionner le filament des lampes avec précision.
In a preferred embodiment of the invention, the junction of the groove and the central body of the device comprises a cord forming with
the corresponding lateral face of the groove a support stop for
the planar element engaged in this groove, and which further abuts against the corresponding collar of the nozzle; therefore the mounting dimension between the two grooves is very precise and allows the filament of the lamps to be positioned precisely.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :
Fig. 1 est une vue agrandie d'un dispositif amortisseur établi conformément à l'invention.
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
Fig. 1 is an enlarged view of a damping device established in accordance with the invention.

Fig. 2 est une coupe transversale d'un feu de signalisation dont le porte-ampoule est monté grace à des dispositifs suivant l'invention. Fig. 2 is a cross section of a signaling light, the bulb holder of which is mounted by means of devices according to the invention.

On a illustré en fig. 1 un dispositif amortisseur 10 suivant l'invention comportant à la manière connue un corps central creux grossièrement sphérique 1 prolongé par deux embouts tubulaires axiaux 2, 3, ledit dispositif 10 étant réalisé en une matière élastique telle qu'un caoutchouc naturel ou synthétique. Chacun des embouts tubulaires 2, 3 est pourvu d'une collerette 21, 31 se dressant perpendicuLairement à L'axe général du dispositif. Ces collerettes se situent dans les dispositifs connus jusqu'à présent à la jonction de la face sphérique extérieure du corps 1 et des embouts tubulaires 2 et 3. Illustrated in fig. 1 a damping device 10 according to the invention comprising in the known manner a roughly spherical hollow central body 1 extended by two axial tubular ends 2, 3, said device 10 being made of an elastic material such as natural or synthetic rubber. Each of the tubular ends 2, 3 is provided with a collar 21, 31 standing perpendicularly to the general axis of the device. These flanges are located in the devices known hitherto at the junction of the outer spherical face of the body 1 and the tubular end pieces 2 and 3.

De cette manière, lorsque de tels dispositifs sont utilisés pour réunir élastiquement une plaque 4 teLLe qu'un porte-ampouLe Cfig. 2) par rapport à une plaque fixe ou cloison 5 assujettie à l'embase 6 d'un feu de signalisation 7, on assiste fréquemment à un déplacement du corps central creux 1 de chaque dispositif par rapport soit à la perforation 41 correspondante de la plaque 4, soit par rapport à l'ouverture 51 de la plaque fixe 5 comme indiqué plus haut. In this way, when such devices are used to elastically join a plate 4 such as a bulb holder Cfig. 2) relative to a fixed plate or partition 5 subject to the base 6 of a signaling light 7, there is frequently a displacement of the hollow central body 1 of each device with respect either to the corresponding perforation 41 of the plate 4, or relative to the opening 51 of the fixed plate 5 as indicated above.

On notera que pour une bonne suspension du porte-ampoule 4 par rapport à la cloison fixe 5, on utilise de préférence trois dispositifs 10 disposés aux trois sommets d'un triangle équilatéral. Autrement dit, en fig. 2, un dispositif 10 non représenté se trouve en avant du plan de coupe. It will be noted that for a good suspension of the bulb holder 4 relative to the fixed partition 5, three devices 10 are preferably used, arranged at the three vertices of an equilateral triangle. In other words, in fig. 2, a device 10 not shown is located in front of the cutting plane.

Conformément à l'invention, l'on ménage au niveau de chacune des jonctions du corps 1 avec les embouts 2 et 3 une gorge périphérique 8, 9 dont la largeur correspond à celle des plaques 4 et 5. Pour renforcer le maintien du dispositif par rapport auxdites plaques, on a fait comporter au corps 1 deux cordons 11, 12 s'étendant vers l'extérieur et dont la face Latérale lla, 12a prolonge la face correspondante de la gorge 8, respectivement 9 de manière à constituer une butée d'appui précise à surface significative pour les plaques 4 et 5 en vis-à-vis des collerettes 21 et 31. In accordance with the invention, a peripheral groove 8, 9, the width of which corresponds to that of the plates 4 and 5, is provided at each of the junctions of the body 1 with the end pieces 2 and 3, in order to reinforce the holding of the device by with respect to said plates, the body 1 has had two cords 11, 12 extending outwards and the lateral face 11a, 12a of which extends the corresponding face of the groove 8, respectively 9 so as to constitute a stop for precise support with significant surface area for plates 4 and 5 opposite the flanges 21 and 31.

De cette manière, le dispositif peut vibrer et amortir les déplacements de ta plaque 4 par rapport à celle 5, mais en évitant tout déplacement ou fluage du corps 1 par rapport auxdites plaques, de telle sorte qu'on est assuré que la plaque 4 au repos et en fonctionnement reprend exactement sa place initiale en replaçant L'ampoule 13 exactement à l'endroit désiré dans l'espace.  In this way, the device can vibrate and dampen the movements of your plate 4 relative to that 5, but avoiding any displacement or creep of the body 1 relative to said plates, so that it is ensured that plate 4 at rest and in operation returns exactly to its original place by replacing the bulb 13 exactly at the desired location in space.

Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents.  It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
