Abstract

The quick connector of a male coupling (1) to a female coupling (2) comprises locking cam-tilting mechanisms (10) from heads (16) located on the axes of rotation of the cams, thereby enabling remote control of the rotation of the retaining cams by means of a tool attached at the tip of a long handle which is rotated.

Description

RACCORDEMENT D'EMBOUTS CONNECTION OF END CAPS
DESCRIPTIONDESCRIPTION
Le sujet de cette invention est un raccordement d'embouts de connexion de tuyaux. Les embouts de connexion sont nombreux et de genres différents, mais on s'intéresse ici à la conception d'un embout qui soit manipulé à distance par un outil situé au bout d'une perche et qui n'impose que des mouvements simples. Les raccords usuels n'ont pas cette facilité de manipulation, ce qui est préjudiciable quand on doit s'occuper d'ouvrir ou de fermer les raccordements de tuyaux menant à des appareils tels que des filtres immergés au fond d'une piscine et susceptibles d'être irradiants : les raccords utilisés jusqu'à maintenant obligent à employer un pont roulant pour relever l'appareil et porter les raccords à la surface où ils sont maniés, ce qui impose à la fois des embarras dus à cette manœuvre fastidieuse et des risques de contamination. Le raccord de l'invention appartient à laThe subject of this invention is a connection of pipe connection end pieces. The connection ends are numerous and of different kinds, but we are interested here in the design of an end piece which is manipulated remotely by a tool located at the end of a pole and which requires only simple movements. The usual fittings do not have this ease of handling, which is detrimental when one has to deal with opening or closing the pipe connections leading to devices such as filters immersed in the bottom of a pool and susceptible to '' be irradiating: the fittings used until now oblige to use an overhead crane to raise the device and bring the fittings to the surface where they are handled, which imposes both embarrassments due to this tedious maneuver and risks contamination. The connector of the invention belongs to the
"famille des raccords rapides, où la connexion est assurée par un seul mouvement, plus simple qu'un vissage ; elle consiste en un perfectionnement d'un raccord existant, où un raccord femelle -dans lequel un raccord mâle est enfoncé- est muni de deux cames articulées et qu'il est possible de déplacer par des leviers : les cames pénètrent dans la paroi du raccord femelle, où sont ménagées des encoches, puis dans une gorge du raccord mâle quand celui-ci a été placé, pour le retenir à l'état connecté. Mais ce système est insuffisant pour l'application envisagée, puisqu'il n'est pas possible de saisir ni de faire tourner des leviers à une distance de plusieurs mètres . Le raccord de l'invention se distingue du précédent en ce qu'il comprend un berceau de réception, pour l'embout femelle et qui est situé sous et devant l'embout mâle, et aussi en ce que les moyens de rotation des cames consistent en des têtes situées sur les axes d'articulation des cames, et que des butées d'arrêt en rotation existent entre l'embout femelle et l'embout mâle. Ainsi, le raccord est amélioré sous trois aspects différents : la jonction préliminaire des embouts est facilitée par le berceau ; la rotation des cames peut être accomplie par un simple mouvement de rotation sur des têtes faciles à saisir et à tourner par un outil tel qu'une clé usuelle soudée au bout d'une perche ; et les butées limitent la rotation des embouts l'un sur l'autre quand l'outil pèse sur les cames en accomplissant sa manœuvre. " family of quick couplings, where the connection is ensured by a single movement, simpler than a screwing; it consists of an improvement of an existing fitting, where a female fitting - in which a male fitting is pushed in - is provided with two articulated cams that can be moved by levers: the cams penetrate into the wall of the female connector, where notches are made, then into a groove of the male connector when it has been placed, to keep it in the connected state. However, this system is insufficient for the intended application, since it is not possible to grasp or rotate levers at a distance of several meters. The connector of the invention differs from the previous one in that it comprises a receiving cradle, for the female end piece and which is located under and in front of the male end piece, and also in that the means of rotation of the cams consist in heads located on the cam articulation axes, and that rotational stops exist between the female end piece and the male end piece. Thus, the connection is improved in three different aspects: the preliminary joining of the end pieces is facilitated by the cradle; the rotation of the cams can be accomplished by a simple rotational movement on heads which are easy to grasp and turn by a tool such as a conventional key welded to the end of a pole; and the stops limit the rotation of the bits one on the other when the tool weighs on the cams while performing its maneuver.
Plusieurs perfectionnements à cette définition générale peuvent être discernés dans le mode "de réalisation qui sera décrit plus loin. Tout d'abord, le raccord préexistant n'est pas modifié mais complété par des pièces nouvelles, ce qui est plus économique. Ainsi, les têtes de préhension sont solidaires de joues à fourchette enserrant les leviers des cames : la rotation des têtes produit une rotation des joues, puis une rotation des leviers par une poussée des branches de la fourchette. Un autre aspect important est que les tuyaux prennent des orientations diverses en fonction des positions des matériels auxquels ils sont joints, et qu'il n'est pas possible de les saisir à distance pour les tourner. Il est alors utile de régler la position du berceau pour le ramener sous le raccord mâle. Cela est possible si le berceau comprend un collier de serrage, qui peut être serré sur une douille intercalée entre le raccord mâle et le tuyau associé ; et si la douille comprend une portée de réception de collier de serrage et des mamelons encadrant la portée de réception, il est possible de desserrer et de resserrer le collier, et les mamelons empêchent le collier de glisser le long de la douille. II est bon que le collier comprenne une' tête de serrage à section identique aux têtes de préhension, afin que toutes les têtes puissent être saisies et tournées par le même outil.Several improvements to this general definition can be discerned in the "embodiment which will be described later. First, the preexisting fitting is not modified but supplemented by new parts, which is more economical. gripping heads are integral with fork cheeks enclosing the cam levers: the rotation of the heads produces a rotation of the cheeks, then a rotation of the levers by a pushing of the branches of the fork. Another important aspect is that the pipes take various orientations depending on the positions of the materials to which they are attached, and that it is not possible to grasp them from a distance to turn them. It is then useful to adjust the position of the cradle to bring it back under the male connector. This is possible if the cradle includes a hose clamp, which can be tightened on a sleeve interposed between the male fitting and the associated pipe; and if the socket includes a collar receiving area and nipples framing the receiving area, it is possible to loosen and tighten the collar, and the nipples prevent the collar from sliding along the socket. It is good that the collar includes a 'tightening head with identical section to the gripping heads, so that all the heads can be grasped and turned by the same tool.
L'invention sera maintenant décrite en détail au moyen des figures suivantes qui en représentent une réalisation préférée :The invention will now be described in detail by means of the following figures which represent a preferred embodiment:
- la figure 1 illustre les conditions de "service et de manipulation du raccord,- Figure 1 illustrates the conditions of " service and handling of the connector,
- et les figures 2, 3 et 4 sont trois vues différentes du raccord.- And Figures 2, 3 and 4 are three different views of the connector.
Le raccord est en général référencé par A. Un embout mâle porte la référence 1, et un embout femelle la référence 2. Ils sont situés au bout des tuyaux respectifs 3 et 4, mais une douille 5 est disposée entre l'embout mâle 1 et son tuyau 3 associé.The connector is generally referenced by A. A male end piece is given the reference 1, and a female end piece is given the reference 2. They are located at the end of the respective pipes 3 and 4, but a socket 5 is placed between the male end piece 1 and its associated pipe 3.
Le raccordement peut être produit par l'engagement d'extrémités filetées 6 de la douille 5 dans des taraudages correspondant de 1 ' embout mâle 1 et du tuyau associé 3, et une portée circulaire 7 lisse s'étend entre ces extrémités filetées. Elle est limitée par des mamelons 8 des deux côtés et dont le but sera expliqué plus loin. L'embout mâle 1 comprend une gorge 9, et l'embout femelle 2 comprend une paire de cames 10 qui lui sont articulées par des axes 11 et sont prolongées par des leviers 12 ; les cames 10 pénètrent dans l'embout femelle 2 en traversant des encoches 13 opérées à travers celui-ci (jusqu'à une profondeur variable régie par l'angle dont on fait basculer les leviers 12) . Dans une position extrême, les cames 10 pénètrent aussi dans la gorge 9 quand l'embout mâle 1 a été installé dans le raccord femelle 2 et contribuent à le bloquer.Connection can be produced by engagement threaded ends 6 of the sleeve 5 in corresponding threads of the male end 1 and the associated pipe 3, and a smooth circular surface 7 extends between these threaded ends. It is limited by nipples 8 on both sides and the purpose of which will be explained later. The male end piece 1 comprises a groove 9, and the female end piece 2 comprises a pair of cams 10 which are articulated to it by pins 11 and are extended by levers 12; the cams 10 enter the female end piece 2 by crossing notches 13 operated through it (to a variable depth governed by the angle whose levers 12 are tilted). In an extreme position, the cams 10 also penetrate into the groove 9 when the male end piece 1 has been installed in the female connector 2 and help to block it.
Les axes 11 traversent des bossages 15 de l'embout femelle 2 où ils sont retenus, et s'étendent au-dehors, finissant en une tête de préhension 16 pouvant prendre l'aspect d'une tête de vis hexagonale terminée par un cône de centrage 17. Des joues 18 s ' étendant parallèlement au levier 12 sont solidaires "des têtes 17, et leur extrémité est munie d'une paire de dents 19 d'une fourchette, entre lesquelles le levier 12 associé est retenu. Une rotation des têtes 16 impose donc une rotation correspondante des joues 18, puis des leviers 12 par l'intermédiaire des dents 19, et enfin des cames 10. Une languette 20 de liaison s'étend entre les axes 11, sous les têtes de préhension 16 et les joues 18, et encore autour d'eux pour finir en deux extrémités recourbées 21. Le mécanisme comprend encore un berceau 22 s' étendant sous l'embout mâle 1 et devant lui, et qu'un collier 23 de serrage, disposé autour de la portée circulaire 1 , maintient en place. Dans cette réalisation, le collier 23 est une cerce continue munie d'un taraudage 24 dans lequel est engagée la tige d'une vis de serrage 25, dont la tête 26 comprend une base hexagonale 27 comme pour les têtes de préhension 16 et une extrémité arrondie ou conique 28. un arceau 35 dépendant du collier 23 retient une portion amincie de la vis de serrage 25 et la rend imperdable .The axes 11 pass through bosses 15 of the female end piece 2 where they are retained, and extend outside, ending in a gripping head 16 which can take the appearance of a hexagonal screw head ending in a cone of 17. centering cheeks 18 extending parallel to lever 12 are integral "heads 17, and their end is provided with a pair of teeth 19 of a fork, between which the associated lever 12 is retained. a rotation of the heads 16 therefore requires a corresponding rotation of the cheeks 18, then of the levers 12 via the teeth 19, and finally of the cams 10. A connecting tongue 20 extends between the axes 11, under the gripping heads 16 and the cheeks 18, and again around them to finish in two curved ends 21. The mechanism includes another cradle 22 extending under the male end piece 1 and in front of it, and a clamping collar 23, arranged around the circular bearing 1, holds in place. In this embodiment, the collar 23 is a continuous hoop provided with a thread 24 in which is engaged the rod of a clamping screw 25, the head 26 of which comprises a hexagonal base 27 as for the gripping heads 16 and one end rounded or conical 28. an arch 35 depending on the collar 23 retains a thinned portion of the clamping screw 25 and makes it captive.
Ce raccord A est plongé à quelques mètres de profondeur dans une piscine et sert à relier un filtre 29 à un autre équipement. Un opérateur saisit un outil 30 composé d'une perche 31 au bout de laquelle est soudée une douille à vis 32 afin de raccorder les embouts 1 et 2 l'un à l'autre. Il se peut d'abord que le berceau 22 soit renversé ou mal placé : l'opérateur desserre alors la vis de serrage 25 pour dégager le collier 23 de la portée 7, puis il peut tourner le berceau 22 en prenant appui sur la vis de serrage 25 pour la remettre à sa position utile commode, sous 1''embout mâle 1 ; puis l'opérateur prend une pince aux branches longues pour saisir l'embout femelle 2, le poser sur le berceau 22 et l'enfoncer autour de l'embout mâle 1 jusqu'à ce qu'il se coince contre un joint d'étanchéité 33. Il reprend alors l'outil 30 et place la douille 32 sur les têtes de préhension 16 pour faire basculer les cames 10 et les faire entrer dans la gorge 9. La connexion est alors complétée. La poussée que l'outil 30 exerce sur les têtes 16 pendant cette opération fait tourner l'embout femelle 2, mais les extrémités des axes 11 viennent buter contre les bords du berceau 22 et limitent donc ce mouvement. La déconnexion s'effectue avec des opérations inverses. This connection A is immersed a few meters deep in a swimming pool and is used to connect a filter 29 to other equipment. An operator grasps a tool 30 composed of a pole 31 at the end of which is welded a screw socket 32 in order to connect the end pieces 1 and 2 to each other. It may first be that the cradle 22 is overturned or improperly placed: the operator then loosens the clamping screw 25 to disengage the collar 23 from the bearing 7, then he can turn the cradle 22 while resting on the screw clamping 25 to return it to its convenient useful position, under 1 '' male end piece 1; then the operator takes a pliers with long branches to grasp the female end piece 2, place it on the cradle 22 and push it around the male end piece 1 until it gets stuck against a seal 33. He then takes up the tool 30 again and places the sleeve 32 on the gripping heads 16 to tilt the cams 10 and bring them into the groove 9. The connection is then completed. The thrust that the tool 30 exerts on the heads 16 during this operation rotates the female end piece 2, but the ends of the axes 11 abut against the edges of the cradle 22 and therefore limit this movement. Disconnection is carried out with reverse operations.
