Description

DISPOSITIF DE PROTECTION D'EMBOUT MALE DE TUYAUTERIE  MALE PIPE PROTECTION DEVICE FOR PIPING
La présente invention concerne un dispositif de protection d' embout mâle de tuyauterie équipé ou non d'au moins un joint torique d'étanchéité et comportant une bride de fixation sur une tuyauterie adj acente . The present invention relates to a protection device male pipe endpiece with or without at least one O-ring sealing and having a fixing flange on an adjoining pipe.
Elle concerne également un système dispositif/tube mettant en œuvre un tel dispositif.  It also relates to a device / tube system implementing such a device.
Elle trouve une application particulièrement importante, bien que non exclusive, dans le domaine de la protection des raccordements de tuyauterie de circuits de climatisation, de circuits de refroidissement, de circuits de frein ou encore de direction assistée automobile, ou de toutes autres canalisations nécessitant leur manutention et/ou leur transport avant montage. Il est en effet nécessaire de protéger l'embout de telles tuyauteries en général muni d'un joint, avant de procéder à leur installation de façon différée.  It finds a particularly important application, although not exclusive, in the field of the protection of the piping connections of air conditioning circuits, cooling circuits, brake circuits or automotive power steering, or any other pipes requiring their handling and / or transport before assembly. It is indeed necessary to protect the tip of such pipes generally provided with a seal, before proceeding with their installation deferred.
On connaît déjà des systèmes de protection d'embouts de canalisation par le biais de chaussettes de protection, qu'on vient enfiler sur les embouts, et/ou de boîtiers amovibles.  We already know the protection of piping tips by means of protective socks, which is put on the end caps, and / or removable housings.
De tels systèmes, qui permettent une protection efficace, présentent cependant des inconvénients.  Such systems, which provide effective protection, however, have disadvantages.
En effet, outre le fait qu'ils risquent d'endommager l'embout et notamment le ou les joints préinstallés, lors de leur mise en place et/ou leur retrait, ils sont coûteux.  Indeed, in addition to the fact that they may damage the tip and including the pre-installed seal (s), when they are put in place and / or removed, they are expensive.
De plus, lorsqu'on souhaite les conserver, il convient alors de les stocker ce qui, ici encore, est un inconvénient car ils sont en général encombrants. La présente invention vise à fournir un dispositif de protection répondant mieux que ceux antérieurement connus aux exigences de la pratique, notamment en ce qu'elle permet un montage facile et en ce qu'elle répond pleinement aux exigences des constructeurs automobiles . In addition, when one wishes to keep them, it is then necessary to store them which, again, is a disadvantage because they are generally bulky. The present invention aims to provide a protection device better than those previously known to the requirements of practice, in particular in that it allows easy assembly and in that it fully meets the requirements of car manufacturers.
Le dispositif selon l'invention présente en effet une excellente tenue aux fluides (huile, eau ...) , est recyclable à 100%, facile à fabriquer et permet une protection du formage parfaite tant en ce qui concerne les salissures (propreté) que les chocs.  The device according to the invention has in fact excellent resistance to fluids (oil, water, etc.), is 100% recyclable, easy to manufacture and provides perfect forming protection both with regard to soiling (cleanliness) and the shocks.
Dans un mode de réalisation, le dispositif est totalement translucide, ce qui permet de voir l'embout sans enlever la protection, par exemple pour vérifier s'il y a lieu si le joint est bien présent sur l'embout.  In one embodiment, the device is totally translucent, which allows to see the tip without removing the protection, for example to check if it is necessary if the seal is present on the tip.
Egalement, dans un autre mode de réalisation de l'invention, les formes tronconiques ou sensiblement tronconiques de l'embase et des parois de l'alvéole vont permettre d'encastrer les dispositifs les uns dans les autres, limitant ainsi les volumes de stockage .  Also, in another embodiment of the invention, the frustoconical or substantially frustoconical shapes of the base and the walls of the cell will allow to embed the devices into each other, thus limiting the storage volumes.
Dans le but de résoudre ces problèmes, l'invention propose notamment un dispositif de protection d'un embout mâle de tuyauterie comprenant une bride de fixation sur une tuyauterie adjacente, caractérisé en ce qu'il est formé d'un capuchon comprenant une alvéole de protection de l'embout en matière plastique rigide ou semi-rigide munie d'une embase annulaire encastrable sur ladite bride, dont le fond est agencé pour former un trottoir d' appui sur la face de jonction de ladite bride avec la tuyauterie adjacente, la paroi de ladite embase étant d'une hauteur h et propre à être située à distance d de la face externe latérale de ladite bride lorsque le fond est en appui dessus, ladite embase comportant des nervures de serrage d'épaisseur e, en saillie vers l'intérieur de l'embase, agencées pour coopérer à frottement avec ladite face externe de la bride, lorsque le dispositif est en place sur l'embout. In order to solve these problems, the invention proposes, in particular, a device for protecting a male piping endpiece comprising a fastening flange on an adjacent pipework, characterized in that it is formed of a cap comprising a honeycomb cell. protection of the tip of rigid or semi-rigid plastic material provided with an annular base flush on said flange, whose bottom is arranged to form a sidewalk support on the junction face of said flange with the adjacent pipe, the wall of said base being of a height h and adapted to be located at a distance d from the lateral external face of said flange when the bottom bears on it, said base comprising thickness clamping ribs e, projecting towards the inside of the base, arranged to cooperate frictionally with said outer face of the flange, when the device is in place on the tip.
Par épaisseur e on entend la dimension transversale maximale hors tout de la nervure qui peut être de section transversale carré, rectangulaire, ovale ou circulaire.  Thickness means the maximum transverse dimension overall of the rib which may be of square, rectangular, oval or circular cross section.
L'épaisseur e est par ailleurs variable dans le sens longitudinal, par exemple de façon linéaire, entre une première valeur, maximale, ei du côté de la périphérie externe de l'embase, et une deuxième valeur minimale e2 au niveau du fond, e2 pouvant être nulle . The thickness e is also variable in the longitudinal direction, for example linearly, between a first maximum value ei on the side of the outer periphery of the base, and a second minimum value e 2 at the bottom, e 2 can be zero.

La présente invention sera mieux comprise à la lecture de la description qui suit de modes de réalisation donné à titre d'exemples non limitatifs. La description se réfère aux dessins qui l'accompagnent dans lesquels : The present invention will be better understood on reading the following description of embodiments given as non-limiting examples. The description refers to the accompanying drawings in which:
Les figures 1 et 2 sont des vues en perspective par le dessus d'un système dispositif/tube selon un mode de réalisation de l'invention respectivement en partie éclatée, et complet.  Figures 1 and 2 are perspective views from above of a device / tube system according to an embodiment of the invention respectively partially exploded and complete.

Les figures 7 et 8 sont, respectivement des vues en perspective et de dessus, d'un autre mode de réalisation du dispositif selon l'invention. Figures 7 and 8 are respectively views in perspective and from above, of another embodiment of the device according to the invention.
La figure 9 est une vue en coupe selon IX-IX de la figure 8.  Figure 9 is a sectional view along IX-IX of Figure 8.
La figure 10 montre le détail X de la figure 9. Figure 10 shows detail X of Figure 9.
Les figures 1 et 2 montrent un dispositif 1 de protection d' un embout mâle 2 de tuyauterie 3 comprenant une bride 4 de fixation sur une tuyauterie adjacente (non représentée). Figures 1 and 2 show a device 1 for protecting a male end 2 of pipe 3 comprising a flange 4 for attachment to an adjacent pipe (not shown).
Le dispositif 1 est formé d'un capuchon 5 comprenant une alvéole 6 propre à englober à distance l'embout sans le toucher, ladite alvéole étant délimitée par une paroi 7 en matière plastique rigide ou semi-rigide translucide munie d'une embase 8 annulaire encastrable sur la bride 4.  The device 1 is formed of a cap 5 comprising a cell 6 adapted to remotely encompass the tip without touching it, said cell being delimited by a wall 7 of translucent rigid or semi-rigid plastic material provided with an annular base 8 flush mounted on flange 4.
L'embase annulaire 8 en surchappement sur le bord 9 de la bride comprend un fond plan 10 en saillie par rapport à la paroi 7 de l'alvéole, vers l'extérieur, d'appui sur la face 11 de jonction de la bride avec la tuyauterie adjacente. La paroi 12 externe de l'embase 8 sensiblement perpendiculaire au fond 10 est de hauteur h et propre à être située à une distance d de la face externe latérale 13 de la bride 4 lorsque le fond 12 est en appui sur la bride. The annular base 8 on the edge 9 of the flange comprises a flat bottom projecting from the wall 7 of the cell, towards the outside, bearing on the face 11 of the junction of the flange with adjacent piping. The outer wall 12 of the base 8 substantially perpendicular to the bottom 10 is of height h and suitable to be located at a distance d from the lateral external face 13 of the flange 4 when the bottom 12 bears on the flange.
L'embase est légèrement tronconique en étant plus large vers l'extérieur, ce qui entraine une distance d variable entre une première valeur di par exemple de 2 mm et une deuxième valeur d2 du côté du fond 10, par exemple de 1 mm.  The base is slightly frustoconical while being wider towards the outside, which causes a variable distance d between a first value di for example of 2 mm and a second value d2 on the side of the bottom 10, for example 1 mm.
L'embase 8 comprend des nervures 14 de serrage d'épaisseur e, en saillie vers l'intérieur de l'embase, et agencées pour coopérer à frottement avec la face externe latérale 13, lorsque le dispositif est encastré sur la bride.  The base 8 comprises ribs 14 clamping thickness e, projecting inwardly of the base, and arranged to cooperate frictionally with the lateral external face 13, when the device is recessed on the flange.
Ici encore, l'épaisseur e_ est variable entre les valeurs ei et e2, avec sensiblement ei = di et e2 = d2, pour permettre le frottement recherché. Here again, the thickness e_ is variable between the values ei and e 2 , with substantially ei = di and e 2 = d 2 , to allow the desired friction.
La hauteur ou profondeur P de l'alvéole 6 est supérieure à la longueur L de l'embout mâle 2 de tuyauterie, la largeur Y du fond 12 de l'embase 8 étant agencée pour que la paroi 7 de l'alvéole ne soit jamais en contact avec la périphérie de l'embout. En fait, dans ce mode de réalisation, la largueur y est supérieure au diamètre de l'embout, qui est centré par rapport à la bride.  The height or depth P of the cell 6 is greater than the length L of the male end 2 of pipe, the width Y of the bottom 12 of the base 8 being arranged so that the wall 7 of the cell is never in contact with the periphery of the tip. In fact, in this embodiment, the width is greater than the diameter of the tip, which is centered relative to the flange.
Une telle disposition permet une excellente protection, toujours à distance, dudit embout, qui va pouvoir comporter des joints 15 exemple toriques d' étanchéité , visibles au travers de l'alvéole.  Such an arrangement allows excellent protection, always at a distance, of said tip, which will be able to include seals O 15 example of sealing, visible through the cell.
Plus précisément, le capuchon 5 est symétrique par rapport à un plan 16 longitudinal. Il comprend un rebord 17 d'extrémité, s' étendant vers l'extérieur de l'embase parallèlement au fond 10, et va permettre à la fois une protection contre le caractère éventuellement coupant qu'aurait pu avoir la périphérie 18 de l'embase, et pour permettre son accrochage par les doigts d'un utilisateur. More precisely, the cap 5 is symmetrical with respect to a longitudinal plane 16. It comprises an end flange 17, extending outward from the base parallel to the bottom 10, and will allow both a protection against the possibly cutting character that could have the periphery 18 of the base, and to allow its attachment by the fingers of a user.
Dans le mode de réalisation plus particulièrement décrit ici, en référence aux figures 1 et 2, l'embase 8 est de forme sensiblement oblongue, munie d'une extrémité 19 plus étroite que le reste 20 de 1 ' embase .  In the embodiment more particularly described here, with reference to FIGS. 1 and 2, the base 8 is of substantially oblong shape, provided with an end 19 narrower than the rest 20 of the base.
Elle présente au moins deux nervures 14 de serrage de part et d'autre de la pointe de 1 ' extrémité 19.  It has at least two clamping ribs 14 on either side of the tip of one end 19.
On a représenté sur les figures 3 à 6 un mode de réalisation d'un dispositif 21 selon l'invention.  FIGS. 3 to 6 show an embodiment of a device 21 according to the invention.
Dans la suite de la description on utilisera les mêmes numéros de référence pour désigner des éléments identiques ou similaires.  In the remainder of the description, the same reference numbers will be used to designate identical or similar elements.
Le dispositif 21 comprend une alvéole 22 sensiblement en forme de cylindre 23 s' écrasant vers l'extrémité 19, ladite alvéole étant fermée vers le haut par une face supérieure solidaire des parois latérales, formant du côté plus étroit par une surface 25 de section ellipsoïdale en forme de coiffe .  The device 21 comprises a substantially cylinder-shaped cell 22 crushing towards the end 19, said cell being closed upwards by an upper surface secured to the side walls, forming on the narrower side by a surface 25 of ellipsoidal section. in the shape of a cap.
Le dispositif 21 comprend l'embase 8 annulaire selon l'invention, s' étendant symétriquement de part et d'autre du plan longitudinal 16.  The device 21 comprises the annular base 8 according to the invention, extending symmetrically on either side of the longitudinal plane 16.
L'alvéole et l'embase présentent ainsi une forme tronconique de volume décroissant du bas vers le haut qui va permettre un encastrement d'un dispositif dans 1 ' autre . Dans ce mode de réalisation deux nervures 26 s'étendent longitudinalement sur une longueur 1 déterminée, par exemple 1cm et sur une hauteur i_ inférieure à la hauteur h de l'embase 8, par exemple dur l/5è à 1/3 de celle-ci. The cell and the base thus have a frustoconical shape decreasing volume from bottom to top which will allow a recess of one device in the other. In this embodiment two ribs 26 extend longitudinally over a length 1 determined, for example 1 cm and a height i_ less than the height h of the base 8, for example hard 1 / 5th to 1/3 of that- this.
Avantageusement l'embase comprend une nervure circulaire longitudinale 27 sur l'arrière (par exemple 1/3 de la demi-circonférence) de l'embase, opposée à l'extrémité 19, les deux nervures 14 symétriques par rapport au plan 16 situé du côté de l'extrémité 19, et, du côté opposé 20, deux jeux de trois nervures, à savoir une nervure étroite 28, une nervure large 29, et une nervure étroite 30, symétriquement par rapport au plan 16.  Advantageously the base comprises a longitudinal circular rib 27 on the rear (for example 1/3 of the half-circumference) of the base, opposite the end 19, the two ribs 14 symmetrical with respect to the plane 16 located on the side of the end 19, and the opposite side 20, two sets of three ribs, namely a narrow rib 28, a wide rib 29, and a narrow rib 30, symmetrically with respect to the plane 16.
De façon à permettre l'emboîtement des dispositifs l'un dans l'autre, la paroi tronconique d'une alvéole est dans le prolongement, de l'extrémité des nervures. Par exemple la paroi arrière 23 est dans le prolongement de l'extrémité 31 de la nervure 27 (trait mixte 32 sur la figure 6) .  In order to allow the interlocking of the devices in one another, the frustoconical wall of a cell is in the extension of the end of the ribs. For example, the rear wall 23 is in the extension of the end 31 of the rib 27 (mixed line 32 in FIG. 6).
Les figures 7 à 10 illustrent un autre mode de réalisation d'un dispositif 33 dont l'embase 8 comporte à partir de l'arrière, une nervure 27 longitudinale sur l'arrière, deux jeux de deux nervures 14, étroites, et deux nervures longitudinales sur l'extrémité.  FIGS. 7 to 10 illustrate another embodiment of a device 33 whose base 8 comprises, from the rear, a longitudinal rib 27 on the rear, two sets of two narrow ribs 14, and two ribs. longitudinal on the end.
On va maintenant décrire en référence aux figures 1 et 2, le fonctionnement de l'ensemble tuyauterie/dispositif selon le mode de réalisation de l'invention plus particulièrement décrit ici.  We will now describe with reference to Figures 1 and 2, the operation of the entire piping / device according to the embodiment of the invention more particularly described here.
Après montage des joints 15 sur l'embout 2, et afin de protéger ce dernier, on vient clipper le capuchon 5 par simple pression, jusqu'à ce que la face 10 du fond 10 de l'embase vienne s'appuyer sur la face 11 en vis à vis de la bride. After assembling the seals 15 on the tip 2, and to protect the latter, the cap 5 is clipped by a simple pressure, until the face 10 of the bottom 10 of the base comes to bear on the face 11 opposite the flange.
Les nervures 14, 26, 27 (figures 4 et8) viennent frotter par leur sommets 32 sur la face externe 13 de la bride, la hauteur h de l'embase étant plus grande que l'épaisseur h_ de la bride laissant un dépassement x de l'embase par rapport à la bride.  The ribs 14, 26, 27 (FIGS. 4 and 8) are rubbed by their vertices 32 on the external face 13 of the flange, the height h of the base being greater than the thickness h_ of the flange, leaving an overhang x of the base relative to the flange.
Les dimensions du capuchon sont bien sûr adaptées à celles de la bride. Le frottement, la forme et la dépassement x par exemple de 3 à 10 mm, permettent une excellente fixation du dispositif, qui ne risque pas de se déboiter, en cas de choc.  The dimensions of the cap are of course adapted to those of the flange. The friction, the shape and the excess x for example from 3 to 10 mm, allow excellent fixation of the device, which is not likely to dislodge, in case of shock.
Quand il s'agit ensuite de faire le montage de la tuyauterie, il suffit alors d'enlever le capuchon en le tirant dans le sens longitudinal de la tuyauterie.  When it comes to the assembly of the piping, it is then sufficient to remove the cap by pulling it in the longitudinal direction of the piping.
Ce dernier, de part sa forme et ses caractéristiques, est en effet facilement préhensible et déboîtable de la bride.  The latter, because of its shape and its characteristics, is indeed easily prehensile and dislodgeable of the flange.
Comme il va de soi et comme il en résulte d'ailleurs de ce qui précède, la présente invention n' est pas limitée aux modes de réalisation plus particulièrement décrits. Elle en embrasse au contraire toutes les variantes et notamment celles où la bride à une forme différente, celles où le capuchon est transparent et non translucide, celles où les nervures sont aménagées différemment, celles où les épaisseurs e des nervures sont différentes entre les nervures d'extrémité et celles de la base.  It goes without saying and as it follows from the foregoing, the present invention is not limited to the embodiments more particularly described. On the contrary, it embraces all the variants and in particular those in which the flange has a different shape, those in which the cap is transparent and non-translucent, those in which the ribs are arranged differently, those in which the thicknesses and ribs are different between the ribs. end and those of the base.
