Description

ORGANE DE MONTAGE ANTI-BRUIT D'UN DISPOSITIF SUR UNE PAROI SUPPORT MUNI DE MOYENS DE PRE-MAINTIEN.  ANTI-NOISE MOUNTING DEVICE OF A DEVICE ON A SUPPORT WALL PROVIDED WITH MEANS OF PRE-MAINTENANCE.
Domaine de l'invention Field of the invention
La présente invention concerne d'une manière générale les organes de montage anti-bruit (également dénommés « silent bloc ») permettant d'assurer la mise en place d'un dispositif mécanique (par exemple, un dispositif d'essuie-glaces) ou électronique (par exemple, un boîtier de servitude intelligent) sur une paroi support telle que le tablier d'interface situé entre le compartiment moteur et l'habitacle d'un véhicule automobile, de sorte à isoler acoustiquement cet habitacle des vibrations sonores émises par le moteur.  The present invention generally relates to anti-noise mounting members (also called "silent block") for ensuring the establishment of a mechanical device (for example, a windscreen wiper device) or electronic device (for example, an intelligent service case) on a support wall such as the interface deck located between the engine compartment and the passenger compartment of a motor vehicle, so as to acoustically isolate this passenger compartment from the sound vibrations emitted by the engine.
Arrière-plan de l'invention Background of the invention
Un tel organe de montage anti-bruit, est notamment décrit dans la demande de brevet américaine US 4,522,378.  Such an anti-noise mounting member is particularly described in US patent application US 4,522,378.
Ce dernier comporte une bague monobloc réalisée dans un matériau élastiquement déformable et dont la face latérale externe présente, dans sa partie centrale, une gorge annulaire s'étendant selon un plan transversal à l'axe de cette bague. Cette gorge annulaire est destinée à recevoir le pourtour annulaire d'une ouverture ménagée dans une âme de fixation (telle qu'une plaque ou un plot) située sur le dispositif (ou sur le bâti supportant ce dispositif) afin de rendre solidaire l'organe de montage anti-bruit de ce dispositif.  The latter comprises a one-piece ring made of an elastically deformable material and whose outer lateral face has, in its central part, an annular groove extending in a plane transverse to the axis of this ring. This annular groove is intended to receive the annular periphery of an opening in a fixing core (such as a plate or a stud) located on the device (or on the frame supporting this device) to make the organ integral. anti-noise mounting of this device.
La bague élastiquement déformable présente un orifice cylindrique axial à travers lequel est inséré un manchon métallique présentant un diamètre externe légèrement plus petit que le diamètre interne de cet orifice axial.  The elastically deformable ring has an axial cylindrical orifice through which is inserted a metal sleeve having an outer diameter slightly smaller than the internal diameter of this axial orifice.
Ce manchon, destinée à être traversé lors du montage du dispositif sur la paroi support par la tige filetée d'un élément de fixation tel qu'une vis ou un goujon coopérant avec un écrou complémentaire, permet de garantir la tension de serrage après vissage de l'écrou sur la tige filetée de la vis. Pour effectuer le montage du dispositif sur la paroi support, l'opérateur doit en premier lieu introduire la tige filetée de l'élément de fixation au travers du manchon de l'organe de montage anti-bruit ainsi que d'un orifice pratiqué dans cette paroi. This sleeve, intended to be traversed during mounting of the device on the support wall by the threaded rod of a fastening element such as a screw or a stud cooperating with a complementary nut, makes it possible to guarantee the tightening tension after screwing of the the nut on the threaded rod of the screw. To mount the device on the support wall, the operator must first insert the threaded rod of the fastener element through the sleeve of the anti-noise mounting member and an orifice made in this wall.
Ce dernier doit ensuite procéder au vissage de l'écrou sur la tige filetée de l'élément de fixation, tout en maintenant l'organe de montage plaqué contre la paroi support.  The latter must then proceed to screw the nut on the threaded rod of the fastener, while maintaining the mounting member pressed against the support wall.
Le plaquage de cet organe de montage anti-bruit monopolisant une première main de l'opérateur, celui-ci ne dispose plus que d'une seule main pour engager l'écrou et procéder à son vissage. De fait, les opérations de fixation du dispositif sur la paroi support sont particulièrement délicates à réaliser, d'autant que ces dernières doivent être réalisées la plupart du temps en aveugle et dans un environnement encombré comme peut l'être par exemple le compartiment moteur d'un véhicule automobile.  The plating of this mounting member anti-noise monopolizing a first hand of the operator, it has more than one hand to engage the nut and proceed to its screwing. In fact, the fixing operations of the device on the support wall are particularly difficult to achieve, especially since they must be made mostly blind and in a congested environment as can be for example the engine compartment of 'a motor vehicle.

Selon l'invention, l'organe de montage anti-bruit 1 comporte également de moyens de pré-maintien en position temporaire du dispositif mécanique ou électronique contre la paroi support 4 sur laquelle il doit être fixé. Ces moyens sont constitués par une languette métallique 30 découpée dans la portion centrale du manchon 20 et rabattue partiellement du côté interne de ce dernier. According to the invention, the anti-noise mounting member 1 also comprises pre-holding means in the temporary position of the mechanical or electronic device against the support wall 4 on which it must be fixed. These means consist of a metal tongue 30 cut in the central portion of the sleeve 20 and partially folded on the inner side of the latter.
Plus précisément, et comme illustré par la figure 1, cette languette 30 s'étend suivant la direction d'insertion de l'élément de fixation 5 en s'inclinant vers l'axe de l'organe de montage 1, de sorte que son extrémité libre frotte le long de la tige filetée de cet élément de fixation 5 lors de la traversée du manchon 20 par cette tige filetée au cours de l'opération de montage du dispositif sur la paroi support 4.  More specifically, and as illustrated in FIG. 1, this tongue 30 extends in the direction of insertion of the fixing element 5 while inclining towards the axis of the mounting member 1, so that its free end rubs along the threaded rod of this fastener 5 during the passage of the sleeve 20 by the threaded rod during the mounting operation of the device on the support wall 4.
Lorsque l'organe de montage 1 vient se plaquer contre cette paroi support 4, la coopération entre l'extrémité libre de la languette 30 et le filet de l'élément de fixation 5 assure le maintien de cet organe de montage 1 contre la paroi support 4.  When the mounting member 1 comes to press against this support wall 4, the cooperation between the free end of the tongue 30 and the thread of the fastening element 5 ensures the maintenance of this mounting member 1 against the support wall 4.
L'opérateur peut ainsi disposer de ses deux mains pour réaliser le vissage de l'écrou sur la tige filetée de l'élément de fixation 5, ce qui permet d'améliorer l'ergonomie du poste de travail et de réduire le temps de montage du dispositif.  The operator can thus have both hands for screwing the nut on the threaded rod of the fastening element 5, which improves the ergonomics of the workstation and reduces the assembly time of the device.
Selon des variantes non représentées, l'organe de montage 1 comporte une pluralité de languettes de pré-maintien telles que 30 (par exemple, 2, 3 ou encore 4) réparties angulairement de manière régulière sur la périphérie du manchon 20, de sorte à obtenir un meilleur centrage de l'organe de montage 1 sur la tige filetée de l'élément de fixation 5.  According to variants not shown, the mounting member 1 comprises a plurality of pre-holding tongues such as 30 (for example, 2, 3 or 4) distributed angularly in a regular manner on the periphery of the sleeve 20, so that obtain a better centering of the mounting member 1 on the threaded rod of the fastening element 5.
On va maintenant décrire à l'appui des figures 3 et 4, l'organe de montage anti-bruit selon un deuxième mode de réalisation de l'invention.  We will now describe the support of Figures 3 and 4, the anti-noise mounting member according to a second embodiment of the invention.
