Device for connecting <B>ä</B> interlocking two 616ments of pipe The present invention relates to a device for connecting <B>ä</B> interlocking two 616ments of pipe, for example made of rigid plastic. , used in particular in irrigation, one <B>ä</B> female end and the other <B>ä</B> male end, this device allowing easy and almost instantaneous assembly and disassembly. This device is characterized in that on the male end is mounted, so as to be <B>ä</B> fixed in translation with respect to <B>ä</B> the corresponding pipe element, a first collar bearing two diametrically opposed tenons, while on the female end is mounted a second collar comprising two openwork lugs diametrically opposed and symmetrical with respect to <B>ä</B> the axis of the said second # me collar, these two ears comprising portions forming hooks intended <B>ä</B> to come into engagement with the tenons of the first collar.
Le dessin annex6 repr6sente, <B>ä</B> titre d'exemple, une forme d'ex6cution du dispositif de raccordement objet de Pinvention. The appended drawing represents, <B>ä</B> by way of example, one form of execution of the connection device which is the subject of the invention.
La fig. <B>1</B> est une vue ext6rieure, avec arrache- ment longitudinal partiel de deux 616ments de cana- lisation munis de ladite forme d'ex6cution du dispo- sitif de raccordement. fig. <B>1</B> is an exterior view, with partial longitudinal tearing away, of two pipe elements provided with said form of execution of the connection device.
La fig. 2 est une coupe longitudinale partielle suivant la ligne 2-2<B>de</B> la fig. <B>1.</B> fig. 2 is a partial longitudinal section along line 2-2<B>of</B> FIG. <B>1.</B>
Les fig. <B>3</B> et 4 repr6sentent en perspective res- pectivement les extr6mit6s mäle et femelle des deux 616ments de canalisation, avant leur r6union. Figs. <B>3</B> and 4 represent in perspective respectively the male and female ends of the two pipe elements, before their reunion.
Suivant les fig. <B>1 ä</B> 4, le dispositif est appliqu6 au raccordement de deux tayaux T, et T2, par exemple en chlorure de polyvinyle rigide, obtenus par extra- sion. According to Figs. <B>1 to</B> 4, the device is applied to the connection of two hoses T1 and T2, for example made of rigid polyvinyl chloride, obtained by extrasion.
Les extr6mit6s <B>ä</B> r6unir, initialement identiques, cylindriques et unies, sont conform6es <B>ä</B> l'int6rieur de deux moules par un proc6d6 d'expansion pneumati- que <B>ä</B> chaud. <B>A</B> la suite de la conformation, ces extr6mit6s ont des dimensions radiales telles que Fune constitue une extr6mit6 mäle et Fautre une extr6mit6 femelle et qu'elles sont pourvues de sail- lies et de creux pour la fixation des organes de liai- sonque comporte le dispositif. The extremities <B>ä</B> to be joined, initially identical, cylindrical and united, are shaped <B>ä</B> inside two molds by a process of pneumatic expansion <B>ä</ B> hot. <B>A</B> Following the shaping, these ends have radial dimensions such that one constitutes a male end and the other a female end and that they are provided with projections and recesses for the fixing of the organs. link comprises the device.
C'est ainsi que l'extr6mit6 mäle du tuyau T, (fig. <B>1</B> et 2) pr6sente une partie cylindrique unie <B>1</B> suivie de deux collerettes 2 m6nageant entre elles une gorge circulaire trap6z6idale <B>3.</B> Dans cette gorge est log6 un collier 4, par exemple m6taUique, pourva de deux tenons diam6tralement oppos6s <B>5</B> en forme de por- tions de nervures eirculaires, <B>ä</B> surfaces actives 5a arqu6es et surfaces avant tronconiques <B>5b</B> (fig. <B>1 ä 3).</B> Thus the male end of the pipe T, (fig. <B>1</B> and 2) has a plain cylindrical part <B>1</B> followed by two flanges 2 forming between them a groove circular trapezoidal <B>3.</B> In this groove is housed a collar 4, for example metal, provided with two diametrically opposed tenons <B>5</B> in the form of portions of circular ribs, <B >ä</B> arched active surfaces 5a and tapered front surfaces <B>5b</B> (fig. <B>1 to 3).</B>
Le collier 4 qui peut servir de moule pour la formation de la gorge circulaire <B>3</B> est fix6 en transla- tion par rapport <B>ä</B> l'616ment T, de canalisation gräce aux collerettes 2, et est fix6 en rotation gräce <B>ä</B> des encoches 20 qui sont paralWes <B>ä</B> Faxe du collier et que vient 6pouser la paroi du tayau T, lors de la n-üse en forme. Ces encoches 20 sont par exemple au nombre de trois, r6parties r6guli#rement dans le sens circonf6rentiel par exempre sur la saillie circulaire interne du collier correspondant <B>ä</B> la gorge <B>3.</B> The collar 4 which can serve as a mold for the formation of the circular groove <B>3</B> is fixed in translation with respect to <B>ä</B> the 616ment T, of pipe thanks to the flanges 2 , and is fixed in rotation thanks <B>ä</B> notches 20 which are paralWes <B>ä</B> Faxe of the collar and that comes 6pouser the wall of the tayau T, during the n-üse in shape . These notches 20 are for example three in number, distributed regularly in the circumferential direction, for example on the internal circular projection of the collar corresponding <B>ä</B> the groove <B>3.</B>
Uemboitement du tuyau T2 comporte une colle- reite <B>6 ä</B> son entr6e, suivie d'une gorge trap6zdidale circulaire <B>7</B> de diametre interne 16g#rement sup6rieur au diamkre externe de l'extr6mit6 cylindrique <B>1</B> Oeu el, fig. 2) suivie 6galement d'une seconde collerette <B>8</B> et d'une partie cylindrique <B>9</B> qui constitue le fond de l'emboitement et est raccord6e par un chanfrein <B>10 ä</B> la partie courante du tuyau T2. La partie cylin- drique <B>9</B> a un diam#tre interne superieur au diamkre interne de la gorge <B>7</B> et m6nage un jeu e2 avec l'ex- tr6mit6 cylindrique <B>1</B> du tuyau T,. The fitting of the pipe T2 has a collar <B>6</B> at its inlet, followed by a circular trapezedidal groove <B>7</B> with an internal diameter slightly greater than the external diameter of the end. cylindrical <B>1</B> Oeu el, fig. 2) also followed by a second flange <B>8</B> and a cylindrical part <B>9</B> which constitutes the bottom of the socket and is connected by a chamfer <B>10 to </B> the current part of the pipe T2. The cylindrical part <B>9</B> has an internal diameter greater than the internal diameter of the groove <B>7</B> and has a clearance e2 with the cylindrical end <B>1 </B> of the pipe T,.
Dans la gorge cireulaire <B>7</B> est ancr6 un collier <B>11,</B> par exemple mAallique, de la m8me mani#re que le collier <B>5</B> dans la gorge <B>3</B> de l'extr6mit6 mäle. Le collier<B>11</B> comporte deux oreilles 21 (fig. 4) diamétralement opposées et symétriques par rapport <B>à</B> Paxe du collier. En outre, ces oreilles sont en sail lie, longitudinalement, au-delà de la tranche #extré- mité de la collerette<B>6</B> du tuyau T.. Chaque oreille 21 comporte, dans le sens circonférentiel, deux par ties, la première est alésée suivant une surface in terne cylindrique 22 de diamètre supérieur<B>à</B> celui des surfaces externes des tenons<B>5</B> pour ménager une entrée<B>à</B> ces tenons, l'autre ajourée en<B>23</B> est profilée<B>à</B> son extrémité en forme de bec<B>à</B> surface tronconique rentrante 24 et constitue un crochet<B>25</B> destiné<B>à</B> venir en prise avec run des tenons<B>5</B> de l'extrémité mâle<B>du</B> tuyau Tl. In the waxy groove <B>7</B> is anchored a collar <B>11,</B> for example maallic, in the same way as the collar <B>5</B> in the groove < B>3</B> from the male end. The collar <B>11</B> comprises two lugs 21 (FIG. 4) diametrically opposed and symmetrical relative <B>to</B> the axis of the collar. In addition, these lugs protrude longitudinally beyond the end edge of the flange <B>6</B> of the pipe T. Each lug 21 comprises, in the circumferential direction, two par ties, the first is bored along a cylindrical inner surface 22 of diameter greater<B>than</B> that of the outer surfaces of the studs<B>5</B> to provide an entry<B>to</B> these tenons, the other perforated at<B>23</B> is profiled<B>at</B> its end in the shape of a beak<B>at</B> re-entrant frustoconical surface 24 and constitutes a hook<B >25</B> intended<B>to</B> come into engagement with a run of tenons<B>5</B> of the male end<B>of</B> pipe Tl.
Chaquel crochet<B>25</B> est séparé de la surface cy lindrique 22 par un cran<B>26</B> de verrouillage (fig. <B>1</B> et 4). La partie cylindrique 22 débouche dans l'évi dement<B>23,</B> mais est partiellement limitée par un res saut<B>27</B> (fig. 4) disposé suivant un plan radial et dia métralement opposé<B>à</B> celui de l'autre oreille. Each hook<B>25</B> is separated from the cylindrical surface 22 by a locking notch<B>26</B> (fig. <B>1</B> and 4). The cylindrical part 22 opens into the recess<B>23,</B> but is partially limited by a res jump<B>27</B> (fig. 4) disposed along a radial and diametrically opposite plane< B>to</B> the other ear.
Par ailleurs, une rondelle & étanchéité <B>15, à</B> deux lèvres concentriques, est placée dans le logement formé par la collerette<B>8,</B> les lèvres étant du côté du fond de l'emboîtement. Le diamètre interne de la rondelle<B>15 à</B> l'état libre est inférieur au diamètre externe de rextrémité <B>1</B> du tuyau TI. In addition, a sealing washer <B>15, with</B> two concentric lips, is placed in the housing formed by the flange<B>8,</B> the lips being on the bottom side of the socket . The internal diameter of the washer<B>15</B> in the free state is less than the external diameter of the end <B>1</B> of the TI pipe.
Le raccordement s'effectue en rapprochant les deux tuyaux Tl et<U>T.</U> de manière que chaque tenon<B>5</B> du collier 4 du tuyau Tl se trouve en face de l'évi dement 22 de l'une des oreilles du collier<B>11</B> du tuyau T2. Une poussée axiale exercée sur le tuyau Tl fait pénétrer son extrémité cylindrique<B>1</B> dans la rondelle d7étanchéité <B>15</B> en comprimant radialement celle-ci. Lorsque chaque tenon<B>5</B> a dépassé axiale- ment le cran<B>26</B> du crochet<B>25</B> correspondant, une rotation dans le sens des aiguilles d7une montre est exercée sur le tuyau Tl afin d'amener chaque tenon <B>5</B> au droit de la partie ajourée de l'oreille 21 en<B>dé-</B> passant ledit cran<B>de</B> verrouillage<B>26.</B> The connection is made by bringing the two pipes T1 and <U>T.</U> together so that each tenon<B>5</B> of the collar 4 of the pipe T1 is opposite the recess 22 one of the lugs of the collar<B>11</B> of pipe T2. An axial thrust exerted on the pipe T1 causes its cylindrical end <B>1</B> to penetrate into the sealing washer <B>15</B>, compressing the latter radially. When each stud<B>5</B> has axially passed the notch<B>26</B> of the corresponding hook<B>25</B>, a clockwise rotation is exerted on the the pipe T1 in order to bring each tenon <B>5</B> to the right of the openwork part of the lug 21 by <B>de-</B> passing said notch<B>of</B> locking <B>26.</B>
Lorsque la canalisation est sous pression, la pres sion exerce des efforts de traction de déboîtement tendant<B>à</B> ramener les tenons<B>5</B> vers l'arrière, en prise sur les crochets<B>25</B> des oreilles 21. When the pipe is under pressure, the pressure exerts disengagement tensile forces tending<B>to</B> bring the tenons<B>5</B> to the rear, in engagement with the hooks<B> 25</B> ears 21.
Cet assemblage est indéboîtable grâce aux crans <B>de</B> verrouillage<B>26</B> et aux ressauts<B>27.</B> Il faut en effet après une poussée axiale, une rotation en sens inverse des aiguilles d!une montre pour dégager les tenons<B>5</B> des crochets<B>25</B> et les ramener en face des évidements cylindriques 22 qui leur laissent toute liberté axiale. La pression de l'eau ne peut pas exercer cette rota tion. This assembly cannot be disengaged thanks to the <B>de</B> locking notches<B>26</B> and the projections<B>27.</B> After an axial thrust, rotation in the opposite direction is required the hands of a watch to disengage the studs<B>5</B> from the hooks<B>25</B> and bring them back in front of the cylindrical recesses 22 which allow them full axial freedom. Water pressure cannot exert this rotation.
Pour séparer les deux tuyaux, on opère en sens inverse. To separate the two pipes, operate in the opposite direction.
Une certaine déviation angulaire est possible en tre les deux tuyaux grâce au jeu radial el entre rex- trémité <B>1</B> du tuyau Tl et la surface interne du tuyau T. au niveau de la garge <B>7</B> d'une part, et au jeu ra dial e2, un peu plus important entre ]!extrémité<B>1</B> du tuyau Tl et la partie<B>9</B> du tuyau T2 d'autre part. Cette déviation angulaire est permise également grâce aux faces (Tappui arquées des tenons<B>5</B> sur les crochets <B>25</B> des oreilles 21 et grâce aux ajourements <B>23</B> de ces oreilles laissant un certain jeu axial aux tenons<B>5</B> comme on le voit aux fig. <B>1</B> et 2. A certain angular deviation is possible between the two pipes thanks to the radial play el between the end <B>1</B> of the pipe T1 and the internal surface of the pipe T. at the level of the garge <B>7</ B> on the one hand, and at the radial clearance e2, a little greater between ]!end<B>1</B> of pipe T1 and part<B>9</B> of pipe T2 on the other go. This angular deviation is also permitted thanks to the faces (Tarched support of the tenons<B>5</B> on the hooks <B>25</B> of the lugs 21 and thanks to the openwork <B>23</B> of these lugs leaving some axial play at the tenons<B>5</B> as seen in Fig. <B>1</B> and 2.
En outre, les organes d'accrochage, tenons<B>5</B> et crochets<B>25</B> des oreilles 21, présentent avantageuse ment de larges faces d%ppui qui assurent fermement la solidité de l'assemblage. In addition, the attachment members, tenons<B>5</B> and hooks<B>25</B> of the lugs 21 advantageously have large supporting faces which firmly ensure the solidity of the assembly. .
Les oreilles 21 sont robustes et d'un encombre ment axial réduit au minimum puisqu'il suffit que leur partie ajourée<B>23</B> soit d7une longueur axiale<B>lé-</B> gèrement supérieure<B>à</B> celle des tenons<B>5</B> augmentée de l'épaisseur des crans de verrouillage<B>26,</B> ces deux dimensions étant relativement faibles. The lugs 21 are robust and of axial bulk ment reduced to a minimum since it suffices that their perforated part<B>23</B> be of an axial length<B>l-</B> greater<B>than </B> that of the tenons<B>5</B> increased by the thickness of the locking notches<B>26,</B> these two dimensions being relatively small.
Par ailleurs, les surfaces tronconiques rentrantes 24 des crochets<B>25</B> du tuyau T2 sur lesquelles peuvent glisser les surfaces<B>5b</B> des tenons<B>5</B> du tuyau Tl lors du rapprochement des deux tuyaux, permettent d'ali gner parfaitement les deux tuyaux avant leur assem blage. Furthermore, the re-entrant frustoconical surfaces 24 of the hooks<B>25</B> of the pipe T2 on which the surfaces<B>5b</B> of the studs<B>5</B> of the pipe T1 can slide during bringing the two pipes together, allow the two pipes to be perfectly aligned before they are assembled.
Enfin, les extrémités mâle et femelle sont faciles <B>à</B> nettoyer sans outil spécial. Finally, the male and female ends are easy <B>to</B> clean without special tools.
