Description

L'invention concerne un élément de protection. Plus particulièrement, l'invention concerne un élément de protection apte à protéger un flexible d'échappement de véhicule automobile.The invention relates to a protection element. More particularly, the invention relates to a protection element adapted to protect a motor vehicle exhaust pipe.

Actuellement, les lignes d'échappements de certains véhicules automobiles sont composées d'un assemblage de pots et de tubes dans lequel un flexible assure la liaison entre la ligne d'échappement et le collecteur d'échappement du moteur. Le flexible d'échappement étant un élément relativement fragile, on le protège des chocs par un élément protecteur qui vient protéger le flexible jusqu'au moment du montage de l'ensemble d'échappement sur le véhicule. On approche donc la ligne d'échappement du collecteur, on retire l'élément protecteur et on solidarise la ligne sur le véhicule, généralement par deux écrous.At present, the exhaust lines of certain motor vehicles are composed of an assembly of pots and tubes in which a hose provides the connection between the exhaust line and the exhaust manifold of the engine. The exhaust hose being a relatively fragile element, it is protected from shocks by a protective element that protects the hose until the assembly of the exhaust assembly on the vehicle. The manifold exhaust line is thus approached, the protective element is removed and the line is secured to the vehicle, generally by two nuts.

Actuellement, l'élément protecteur est composé de deux demi-coquilles identiques en matière plastique, qui viennent protéger le flexible.Currently, the protective element is composed of two identical half-shells made of plastic, which protect the hose.

D'une part, cet élément protecteur est volumineux, ce qui pose des problèmes d'encombrements lors de l'approche de la ligne d'échappement dans des espaces réduits, notamment dus à la présence de composants tels que la transmission, des écrans thermiques, les éléments de la direction, etc.On the one hand, this protective element is bulky, which poses congestion problems when approaching the exhaust line in small spaces, especially due to the presence of components such as transmission, heat shields , the elements of management, etc.

D'autre part, le retrait de l'élément protecteur est relativement peu aisé par l'opérateur et ceci du à sa trop grande rigidité dans l'espace réduit ou il se trouve.On the other hand, the removal of the protective element is relatively easy by the operator and this due to its excessive rigidity in the reduced space where it is located.

Par ailleurs, comme décrit notamment dans les documents US 2002/117540 et DE 20 2004 001197 , il existe déjà des éléments protecteurs, dont la structure en lamelles articulées permet une meilleure manipulation pour entourer un élément à protéger. Toutefois, de tels éléments protecteurs sont volumineux, difficiles à manipuler, spécifiquement dédiés au domaine de l'emballage et ne peuvent s'adapter à un flexible d'échappement.Moreover, as described in particular in the documents US 2002/117540 and DE 20 2004 001197 there are already protective elements, whose structure articulated slats allows better handling to surround an element to protect. However, such protective elements are bulky, difficult to handle, specifically dedicated to the field of packaging and can not adapt to an exhaust hose.

L'invention a pour objectif de remédier à l'ensemble des inconvénients ci-dessus et de proposer un élément protecteur moins volumineux et plus aisé à retirer de l'organe qu'il protège.The object of the invention is to overcome all the above disadvantages and to propose a less bulky and easier protective element to be removed from the organ that it protects.

Selon un premier aspect de l'invention, il s'agit d'un élément protecteur destiné à entourer un organe à protéger et constitué par une plaque constituée de plusieurs lamelles, les bords longitudinaux de ces lamelles étant reliés entre eux par un moyen d'articulation pour que la plaque puisse être pliée autour dudit organe, un dispositif de fermeture étant prévu pour maintenir cette plaque pliée autour dudit organe et les lamelles comprenant sur au moins une de leurs extrémités opposées au moins une excroissance.According to a first aspect of the invention, it is a protective element intended to surround an organ to be protected and constituted by a plate consisting of several lamellae, the longitudinal edges of these lamellae being connected to one another by means of articulation so that the plate can be folded around said member, a closure device being provided to maintain the plate bent around said member and the lamellae comprising on at least one of their ends opposite at least one protrusion.

Un élément protecteur muni de telles excroissances permet notamment de le positionner en regard d'au moins un trou d'une bride servant à la fixation d'un autre organe. De telles excroissances permettent également d'empêcher l'opérateur de fixer l'organe à protéger sans avoir au préalable retiré l'élément protecteur.A protective element provided with such outgrowths allows in particular to position it facing at least one hole of a flange for fixing another member. Such growths also make it possible to prevent the operator from fixing the organ to be protected without having first removed the protective element.

Du fait de sa structure en lamelles articulées, l'élément protecteur selon l'invention est beaucoup plus facile à monter sur l'organe à protéger et à retirer de celui-ci, notamment lorsque l'espace environnent est très encombré.Due to its articulated lamella structure, the protective element according to the invention is much easier to mount on the body to be protected and removed from it, especially when the surrounding space is very congested.

Avantageusement, l'élément protecteur comprend au moins trois lamelles. Le nombre de lamelles est fonction de leur largeur ainsi que de la circonférence de l'organe à protéger.Advantageously, the protective element comprises at least three lamellae. The number of lamellae is a function of their width as well as the circumference of the organ to be protected.

Dans une application préférée, l'élément protecteur est monobloc. Par monobloc, on comprend qu'il est composé d'une seule pièce réalisée par exemple par moulage.In a preferred application, the protective element is monobloc. By monobloc, it is understood that it is composed of a single piece made for example by molding.

En particulier, le dispositif de fermeture est prévu sur les deux lamelles situées aux extrémités opposées de la plaque.In particular, the closure device is provided on the two strips located at the opposite ends of the plate.

Avantageusement, chaque lamelle présente une épaisseur allant de l'ordre de 2 mm à 6 mm, avantageusement de l'ordre de 3 mm.Advantageously, each lamella has a thickness ranging from about 2 mm to 6 mm, advantageously of the order of 3 mm.

En particulier, chaque lamelle présente une largeur allant de l'ordre de 1 cm à 3 cm, avantageusement de l'ordre de 1,5 cm à 2,5 cm.In particular, each lamella has a width ranging from 1 cm to 3 cm, advantageously of the order of 1.5 cm to 2.5 cm.

Dans une application préférée, le au moins un moyen d'articulation entre au moins deux lamelles est notamment un rétrécissement de l'épaisseur de la matière entre ces lamelles. Ce rétrécissement doit être d'une part suffisamment mince pour assurer une souplesse à l'ensemble et lui permettre de s'enrouler autour de l'organe à protéger et d'autre part suffisamment épais pour lui assurer de la solidité. La solidité de l'ensemble est notamment importante si l'on souhaite réutiliser l'élément protecteur plusieurs fois.In a preferred application, the at least one means of articulation between at least two lamellae is in particular a narrowing of the thickness of the material between these lamellae. This narrowing must be on the one hand thin enough to ensure flexibility to all and allow it to wrap around the body to protect and secondly thick enough to ensure the solidity. The strength of the assembly is particularly important if one wishes to reuse the protective element several times.

Avantageusement, le rétrécissement s'étend sur tout ou partie de la longueur de chaque lamelle.Advantageously, the narrowing extends over all or part of the length of each lamella.

En particulier, le rétrécissement présente une épaisseur allant de l'ordre de 0.2 mm à 0.9 mm, avantageusement de l'ordre de 0.5 mm.In particular, the narrowing has a thickness ranging from about 0.2 mm to 0.9 mm, preferably of the order of 0.5 mm.

Avantageusement, chaque lamelle comprend au moins une première partie apte à recevoir une tige apte à venir dans le prolongement d'une seconde partie d'une lamelle avoisinante apte à recevoir ladite tige, l'ensemble première partie, deuxième partie et tige formant une articulation.Advantageously, each lamella comprises at least a first portion adapted to receive a rod adapted to come in the extension of a second portion of a neighboring lamella adapted to receive said rod, the entire first part, second portion and rod forming a joint .

En particulier, le dispositif de fermeture est formé d'au moins un clip comprenant au moins un élément femelle à une lamelle d'extrémité et au moins un élément mâle sur l'autre lamelle d'extrémité, le au moins un élément femelle étant apte à coopérer avec le au moins un élément mâle.In particular, the closure device is formed of at least one clip comprising at least one female element with an end plate and at least one male element on the other end plate, the at least one female element being suitable to cooperate with the at least one male element.

Avantageusement, les lamelles sont au moins en partie composées de matière plastique. L'homme du métier pourra avantageusement utiliser d'autres matériaux tels que des matériaux composites ou des matériaux métalliques tels que par exemple des feuilles d'aluminium, voire des composants en nid d'abeille.Advantageously, the slats are at least partially made of plastic. Those skilled in the art may advantageously use other materials such as composite materials or metallic materials such as for example aluminum sheets or even honeycomb components.

L'invention concerne également l'utilisation d'un élément protecteur pour protéger un organe d'une ligne d'échappement lors de son déplacement et de son montage sur un collecteur d'échappement.The invention also relates to the use of a protective element to protect a member of an exhaust line during its movement and its mounting on an exhaust manifold.

L'invention est maintenant décrite en faisant référence aux dessins, non limitatifs, dans lesquels :

  • La figure 1 est une vue d'un élément protecteur selon l'art antérieur dans son milieu d'intégration.
  • La figure 2 est une vue d'ensemble d'un élément protecteur selon l'invention, avant de se mettre en place sur l'organe à protéger.
  • La figure 3 est une vue de l'élément protecteur selon l'invention, en cours de montage sur un organe à protéger.
  • La figure 4 est une vue de l'élément protecteur selon l'invention, après son montage sur l'organe à protéger.
  • La figure 5 est une vue en coupe suivant le plan AA de la figure 4.
The invention is now described with reference to the non-limiting drawings, in which:
  • The figure 1 is a view of a protective element according to the prior art in its integration medium.
  • The figure 2 is an overview of a protective element according to the invention, before being put in place on the body to be protected.
  • The figure 3 is a view of the protective element according to the invention, being mounted on an organ to be protected.
  • The figure 4 is a view of the protective element according to the invention, after its mounting on the body to be protected.
  • The figure 5 is a sectional view according to the plan AA of the figure 4 .

La figure 1 représente un mode de réalisation d'un élément protecteur 1 selon l'art antérieur. Cet élément protecteur 1 comprend deux demi-coques identiques en matière plastique 101 et 102 comprenant chacune un élément de fermeture mâle 101a et un élément de fermeture femelle 101b aptes à coopérer réciproquement avec l'élément mâle 102a et l'élément femelle 102b de la coque opposée pour verrouiller les deux demi-coques autour de l'organe 40 à protéger, qui, dans cet exemple, est un flexible de ligne d'échappement.The figure 1 represents an embodiment of a protective element 1 according to the prior art. This protective element 1 comprises two identical half-shells made of plastics material 101 and 102 each comprising a male closure element 101a and a female closure element 101b able to cooperate with the male element 102a and the female element 102b of the shell. opposite to lock the two half-shells around the member 40 to protect, which in this example is an exhaust line hose.

L'élément protecteur 1 est positionné autour du flexible 40 de la ligne d'échappement 200. Le flexible 40 est fixé au collecteur 300 d'échappement du véhicule.The protective element 1 is positioned around the hose 40 of the exhaust line 200. The hose 40 is attached to the exhaust manifold 300 of the vehicle.

Autour de l'élément protecteur 1 sont disposés divers éléments du véhicule, tel qu'un arbre de transmission 400 et un écran thermique 500.Around the protective element 1 are arranged various elements of the vehicle, such as a transmission shaft 400 and a heat shield 500.

Dans l'exemple représenté, la distance entre l'élément protecteur 1 et l'écran thermique 500, qui est l'organe du véhicule le plus proche du protecteur, est de l'ordre de 25 mm.In the example shown, the distance between the protective element 1 and the heat shield 500, which is the body of the vehicle closest to the protector, is of the order of 25 mm.

Cette faible distance rend difficile le retrait de l'élément protecteur 1.This short distance makes it difficult to remove the protective element 1.

Les figures 2, 3 et 4 représentent un mode de réalisation particulier de l'invention, l'élément protecteur étant représenté à plat sur la figure 2, en cours de positionnement sur la figure 3 et positionné autour de l'élément flexible 40 à protéger sur la figure 4.The figures 2 , 3 and 4 represent a particular embodiment of the invention, the protective element being represented flat on the figure 2 , being positioned on the figure 3 and positioned around the flexible member 40 to be protected on the figure 4 .

L'élément protecteur 1 est destiné à entourer l'organe 40, c'est-à-dire le flexible, et à couvrir l'organe 40 au moins partiellement. Il est constitué d'une plaque constituée de plusieurs lamelles 10, les bords longitudinaux de ces dernières étant reliés entre eux par un moyen d'articulation 20, pour que la plaque puisse être pliée autour de l'organe 40 à protéger. L'élément protecteur 1 comprend un dispositif de fermeture 30 pour maintenir la plaque pliée autour de l'organe 40 à protéger.The protective element 1 is intended to surround the member 40, that is to say the flexible, and to cover the member 40 at least partially. It consists of a plate consisting of several strips 10, the longitudinal edges of the latter being interconnected by a hinge means 20 so that the plate can be folded around the member 40 to be protected. The protective element 1 comprises a closure device 30 for holding the folded plate around the member 40 to be protected.

Dans cet exemple de réalisation de l'invention, la distance entre l'élément protecteur 1 entourant l'organe 40 et l'écran thermique 500, représentant l'organe du véhicule le plus proche de l'élément protecteur 1, est de l'ordre de 43,7 mm, représentant un gain de place d'au moins 18,7 mm.In this embodiment of the invention, the distance between the protective element 1 surrounding the member 40 and the heat shield 500, representing the body of the vehicle closest to the protective element 1, is of the order of 43.7 mm, representing a space saving of at least 18.7 mm.

Cette distance est ainsi supérieure à celle mentionnée dans le cas du protecteur connu, ce qui facilite son retrait de l'organe 40.This distance is thus greater than that mentioned in the case of the known protector, which facilitates its removal from the member 40.

Le dispositif de fermeture 30 est prévu sur les deux lamelles 11 et 12 situées aux extrémités opposées de la plaque.The closure device 30 is provided on the two strips 11 and 12 located at the opposite ends of the plate.

Dans l'exemple représenté, la première lamelle 11 comprend un élément femelle 31 apte à recevoir un élément mâle 32 de la dernière lamelle 12.In the example shown, the first lamella 11 comprises a female element 31 able to receive a male element 32 of the last lamella 12.

L'élément mâle 32 vient se clipper dans l'élément femelle 31, afin d'assurer le verrouillage de l'élément protecteur 1 dans sa position de protection, quand il est positionné autour de l'organe 40 à protéger.The male element 32 is clipped into the female element 31, to ensure the locking of the protective element 1 in its protective position, when it is positioned around the member 40 to be protected.

Toujours selon l'exemple représenté, chaque lamelle 10, 11 et 12 présente une épaisseur sensiblement de l'ordre de 3 mm. La largeur de chaque lamelle 10, 11 et 12 présente une largeur sensiblement de l'ordre de 2 cm. La longueur de chaque lamelle est fonction de l'organe 40 à protéger. Dans l'exemple, chaque lamelle présente une longueur sensiblement de l'ordre de 20 cm.Still according to the example shown, each strip 10, 11 and 12 has a thickness substantially of the order of 3 mm. The width of each lamella 10, 11 and 12 has a width substantially of the order of 2 cm. The length of each slat depends on the member 40 to be protected. In the example, each lamella has a length substantially of the order of 20 cm.

L'homme du métier adaptera l'épaisseur et la largeur de chaque lamelle 10, 11 et 12 en fonction du matériau utilisé qui est en matière plastique dans notre exemple. De même, il adaptera le nombre de lamelles à utiliser en fonction de la circonférence de l'organe 40 à protéger.The skilled person will adapt the thickness and width of each strip 10, 11 and 12 depending on the material used which is plastic in our example. Similarly, it will adapt the number of slats to be used depending on the circumference of the member 40 to be protected.

Comme représenté sur la figure 4, le moyen d'articulation 20 entre au moins deux lamelles 10, 11 et 12 est un rétrécissement de l'épaisseur de la matière entre ces lamelles. Dans notre exemple, le rétrécissement est de l'ordre de 0,5 mm et s'étend sur toute la longueur de chaque lamelle 10, 11, 12. Selon un mode de réalisation non représenté, le moyen d'articulation pourrait s'étendre seulement en partie, en un, deux ou trois points, entre chaque lamelle.As shown on the figure 4 , the articulation means 20 between at least two lamellae 10, 11 and 12 is a narrowing of the thickness of the material between these lamellae. In our example, the shrinkage is of the order of 0.5 mm and extends over the entire length of each strip 10, 11, 12. According to an embodiment not shown, the hinge means could extend only in part, in one, two or three points, between each lamella.

Un mode de réalisation particulier pourrait consister à insérer un composant textile dans la plaque, assurant une fonction de charnière entre les lamelles 10, 11 et 12.A particular embodiment could include inserting a textile component into the plate, providing a hinge function between the lamellae 10, 11 and 12.

Dans un autre mode de réalisation, non représenté, chaque lamelle 10, 11 et 12 comprend au moins une première partie apte à recevoir une tige apte à venir dans le prolongement d'une seconde partie d'une lamelle 10, 11, 12 avoisinante apte à recevoir ladite tige, l'ensemble première partie, deuxième partie et tige formant articulation 20.In another embodiment, not shown, each strip 10, 11 and 12 comprises at least a first portion adapted to receive a rod adapted to come in the extension of a second part of a lamella 10, 11, 12 adjacent to receive said rod, the whole first part, second part and joint rod 20.

Selon l'invention, les lamelles 10, 11 et 12 comportent sur leurs extrémités des excroissances 10', 10", 11', 11" et 12', 12". Dans notre exemple, les excroissances 10', 11', 12', 10", 11" et 12" sont formées aux extrémités des lamelles 10, 11 et 12 en créant un repli desdites lamelles sur elle mêmes. Ce repli peut être réalisé lors du montage des lamelles. L'homme du métier pourra trouver d'autres modes de réalisation pour créer ces excroissances, tels que, par exemple, ajouter par vissage, collage ou clipsage, voir même soudage, un élément complémentaire formant l'excroissance.According to the invention, the lamellae 10, 11 and 12 have on their ends protuberances 10 ', 10 ", 11', 11" and 12 ', 12 "In our example, the protuberances 10', 11 ', 12' , 10 ", 11" and 12 "are formed at the ends of the slats 10, 11 and 12 creating a fold of said slats on itself. This fold can be achieved during the assembly of the slats. Those skilled in the art can find other embodiments to create these growths, such as, for example, add by screwing, gluing or clipping, or even welding, a complementary element forming the protrusion.

De telles excroissances permettent notamment d'empêcher le vissage de la ligne d'échappement et donc de l'élément flexible 40 sur le collecteur d'échappement par l'opérateur. Ainsi, de telles excroissances rendent nécessaire l'opération de retrait de l'élément protecteur pour pouvoir effectuer le vissage.Such excrescences in particular allow to prevent the screwing of the exhaust line and therefore of the flexible element 40 on the exhaust manifold by the operator. Thus, such growths necessitate the removal operation of the protective element to be able to perform the screwing.

Par ailleurs, selon une application préférée de l'invention, afin d'empêcher le mouvement en translation de l'élément protecteur 1 sur l'organe 40 à protéger, ce dernier peut comporter au moins une rainure, ou une bride, sur la périphérie de ses extrémités, les extrémités des excroissances 10', 11', 12', 10", 11" et 12" venant alors se clipper dans lesdites rainures, ou lesdites brides, de l'organe 40 à protéger.Furthermore, according to a preferred application of the invention, in order to prevent the translational movement of the protective element 1 on the member 40 to be protected, the latter may comprise at least one groove, or a flange, on the periphery its ends, the ends of the protuberances 10 ', 11', 12 ', 10 ", 11" and 12 "then being clipped into said grooves, or said flanges, of the member 40 to be protected.

Pour fixer une ligne d'échappement à un collecteur d'échappement, la ligne d'échappement comprenant un organe 40 recouvert au moins en partie par un élément protecteur 1 tel que décrit précédemment, on procède comme suit :

  • On recouvre au moins en partie l'élément 40 de la ligne d'échappement par l'élément protecteur 1.
  • On positionne la ligne d'échappement 200 sur le collecteur 300.
  • On retire l'élément protecteur 1 de l'élément à protéger 40.
  • On visse la ligne d'échappement 200 sur le collecteur 300.
To fix an exhaust line to an exhaust manifold, the exhaust line comprising a member 40 covered at least in part by a protective element 1 as described above, is carried out as follows:
  • At least part of the element 40 of the exhaust line is covered by the protective element 1.
  • Positioning the exhaust line 200 on the manifold 300.
  • The protective element 1 is removed from the element to be protected 40.
  • The exhaust line 200 is screwed onto the manifold 300.

Les principaux avantages de l'invention sont les suivants :

  • Un encombrement plus réduit de l'élément protecteur 1 que dans l'art antérieur, permettant de faciliter l'approche de la ligne d'échappement 200 du collecteur d'échappement 300.
  • Une facilité de démontage de l'élément protecteur 1 par rapport à l'organe 40 à protéger quand ce dernier est mis en place.
The main advantages of the invention are the following:
  • A smaller footprint of the protective element 1 than in the prior art, to facilitate the approach of the exhaust line 200 of the exhaust manifold 300.
  • An easy disassembly of the protective element 1 relative to the member 40 to be protected when the latter is put in place.

En effet, pour démonter cet élément protecteur 1, il suffit de déverrouiller le dispositif de fermeture et de dérouler l'élément protecteur 1 de l'organe 40, comme un ruban enroulé sur une bobine, ce qui est possible grâce à la structure en lamelles de l'élément protecteur.Indeed, to remove this protective element 1, it is sufficient to unlock the closure device and unwind the protective element 1 of the member 40, as a ribbon wound on a coil, which is possible thanks to the slat structure of the protective element.
