Description

La présente invention concerne un dispositif permettant de maintenir captif au moins un axe d'articulation dans un logement conjugué d'un élément de couronnement, tel qu'une grille ou un tampon, destiné à être monté articulé sur un cadre de support par l'intermédiaire de cet axe.The present invention relates to a device for holding captive at least one hinge axis in a conjugate housing of a cap element, such as a grid or a buffer, intended to be mounted articulated on a support frame by the intermediate of this axis.

L'articulation d'un tel élément de couronnement sur le cadre ne permet pas le démontage ou l'extraction de l'élément de couronnement de son cadre.The articulation of such a crown element on the frame does not allow disassembly or extraction of the crown element of its frame.

Selon l'art antérieur (= GB 2 192 654 A ), l'installation à montage articulé indémontable de l'élément de couronnement à son cadre de support consistait à loger, juste avant la pose de l'élément de couronnement sur le cadre, au moins un axe d'articulation dans un logement réalisé dans un côté de l'élément du couronnement à proximité de sa rive d'articulation au cadre et parallèlement à cette dernière. Une fois l'élément de couronnement posé sur son cadre, un opérateur coulait de la résine dans le logement de l'axe d'articulation de manière à repousser l'axe d'articulation en partie hors de son logement et l'introduire dans une gâche du cadre pouvant être constituée par un trou borgne. Une fois la résine durcie, l'axe d'articulation devient indémontable du cadre.According to the prior art (= GB 2,192,654A ), the installation articulated mount indémontable of the crown member to its support frame was to accommodate, just before the installation of the crown member on the frame, at least one axis of articulation in a housing made in one side of the crown element near its hinge edge to the frame and parallel to the latter. Once the cap element was placed on its frame, an operator poured resin into the housing of the hinge pin so as to push the hinge axis partially out of its housing and introduce it into a striker of the frame that can be constituted by a blind hole. Once the resin hardened, the hinge axis becomes unmountable frame.

Un tel montage a pour inconvénient majeur que l'axe d'articulation peut sortir de son logement de l'élément de couronnement lors de la manipulation de ce dernier pour le poser sur son cadre de support, au risque de le perdre.Such an arrangement has the major disadvantage that the hinge pin can out of its housing of the cap member during handling of the latter to the rest on its support frame, at the risk of losing it.

La présente invention a pour but d'éliminer l'inconvénient ci-dessus en prévoyant un dispositif permettant de rendre captif l'axe d'articulation dans son logement de l'élément de couronnement.The present invention aims to eliminate the above disadvantage by providing a device for making captive the hinge axis in its housing of the cap element.

A cet effet, selon l'invention, le dispositif permettant de maintenir captif au moins un axe d'articulation dans un logement conjugué d'un élément de couronnement, tel qu'une grille ou un tampon, destiné à être monté articulé sur un cadre de support par l'intermédiaire de cet axe, est caractérisé en ce qu'il comprend une goupille amoviblement fixée dans un perçage de l'élément de couronnement transversalement au logement de l'axe d'articulation de manière à retenir axialement cet axe dans le logement à l'encontre de la force de rappel d'un organe élastique monté précontraint dans le logement entre le fond de celui-ci et l'extrémité de l'axe opposée à celle en appui sur la goupille transversale de retenue.For this purpose, according to the invention, the device for keeping captive at least one axis of articulation in a conjugate housing of a cap element, such as a grid or a buffer, intended to be mounted articulated on a frame of support via this axis, is characterized in that it comprises a pin removably fixed in a piercing of the cap member transversely to the housing of the hinge pin so as to axially retain this axis in the housing against the biasing force of an elastic member mounted prestressed in the housing between the bottom thereof and the end of the axis opposite to that bearing on the transverse retaining pin.

De préférence, l'organe élastique de rappel est un ressort hélicoïdal de compression monté dans le logement coaxialement à l'axe d'articulation.Preferably, the elastic return member is a helical compression spring mounted in the housing coaxially with the hinge pin.

L'axe d'articulation a une longueur telle qu'après retrait de la goupille, l'axe fait partiellement saillie de l'élément de couronnement sous l'action de la force de rappel de l'organe élastique.The axis of articulation has a length such that after removal of the pin, the axis partially projects from the cap member under the action of the restoring force of the elastic member.

L'axe d'articulation est avantageusement cylindrique.The hinge axis is advantageously cylindrical.

L'élément de couronnement peut avoir une forme rectangulaire et le logement de l'axe d'articulation est alors réalisé dans un côté de l'élément de couronnement parallèlement à la rive d'articulation correspondante de l'élément de couronnement et à proximité de cette rive.The crown element may have a rectangular shape and the housing of the hinge pin is then made in one side of the crown element parallel to the corresponding hinge edge of the crown element and close to this shore.

Le logement de l'axe d'articulation et le perçage de l'élément de couronnement viennent de fonderie.The housing of the hinge pin and the piercing of the cap element come from foundry.

L'invention vise également un élément de couronnement, tel qu'une grille ou un tampon, notamment pour regard de chaussée, et qui est caractérisé en ce qu'il comprend un dispositif tel que précédemment défini.The invention also relates to a cap element, such as a grid or a buffer, especially for pavement, and which is characterized in that it comprises a device as previously defined.

L'invention vise en outre un procédé d'installation d'un élément de couronnement, tel qu'une grille ou un tampon, à montage articulé sur un cadre de support, l'élément de couronnement étant pourvu d'un dispositif tel que défini précédemment, et qui est caractérisé en ce qu'il consiste à poser l'élément de couronnement sur le cadre avec l'axe d'articulation maintenu captif dans son logement de l'élément de couronnement et à retirer la goupille de l'élément de couronnement de manière à permettre à l'organe élastique de repousser l'axe en partie hors du logement et de l'introduire coaxialement dans un trou borgne formant gâche du cadre.The invention further relates to a method of installing a cap member, such as a grid or a buffer, hingedly mounted on a support frame, the cap member being provided with a device as defined above, and which is characterized in that it consists in placing the cap element on the frame with the hinge pin held captive in its housing of the crown member and removing the pin from the cap member so as to allow the resilient member to push the axis partially out of the housing and introduce it coaxially into a blind hole forming a keeper of the frame.

En se reportant aux figures, la référence 1 désigne un cadre qui présente une forme rectangulaire et sur lequel est articulé un élément de couronnement 2 constitué dans le cas présent par une grille, étant bien entendu que l'élément de couronnement 2 peut être constitué par un tampon ou couvercle.Referring to the figures, the reference numeral 1 denotes a frame which has a rectangular shape and on which is articulated a cap element 2 constituted in this case by a grid, it being understood that the cap element 2 may be constituted by a tampon or lid.

Le cadre 1 est noyé dans la chaussée de manière que l'élément de couronnement 2 permette d'obturer un regard de chaussée.The frame 1 is embedded in the pavement so that the cap element 2 makes it possible to close a manhole.

L'élément de couronnement 2 a sa rive 3 montée articulée à la rive correspondante 4 du cadre 1 suivant un axe d'articulation X1, X2 s'étendant parallèlement aux rives 3, 4.The coronation element 2 has its bank 3 mounted articulated to the corresponding bank 4 of the following frame 1 a hinge axis X1, X2 extending parallel to the banks 3, 4.

L'articulation de l'élément de couronnement 2 au cadre 1 est du type ne permettant pas le démontage ou l'extraction de l'élément 2 de son cadre.The articulation of the crown element 2 to the frame 1 is of the type that does not allow the dismantling or extraction of the element 2 from its frame.

L'élément de couronnement 2 est logé, à sa position de fermeture du cadre 1, dans une feuillure 5 du cadre 1 et peut reposer sur un joint périphérique 6 logé dans la feuillure afin de diminuer les bruits de montage de l'élément 2 dans son cadre.The cap member 2 is housed, in its closed position of the frame 1, in a rabbet 5 of the frame 1 and can rest on a peripheral seal 6 housed in the rabbet to reduce the mounting noise of the element 2 in its frame.

Selon l'invention, avant montage articulé de l'élément de couronnement 2 dans son cadre 1, l'élément de couronnement 2 est pourvu d'au moins un axe cylindrique d'articulation 7 emprisonné de façon imperdable dans un logement conjugué 8 réalisé dans l'élément de couronnement 2 et débouchant d'un côté de ce dernier.According to the invention, before articulated mounting of the cap member 2 in its frame 1, the cap member 2 is provided with at least one cylindrical axis of articulation 7 captively imprisoned in a conjugate housing 8 made in the coronation element 2 and opening on one side of the latter.

Le logement 8 est réalisé dans la rive d'articulation 3 de l'élément 2 à partir du côté de cet élément en s'étendant parallèlement à cette rive et coaxialement à l'axe d'articulation X1, X2.The housing 8 is formed in the hinge side 3 of the element 2 from the side of this element extending parallel to this side and coaxially with the axis of articulation X1, X2.

L'axe d'articulation 7 est maintenu captif dans son logement 8 par une goupille 9 amoviblement fixée dans un perçage 10 de l'élément de couronnement 2 et réalisé perpendiculairement à l'axe longitudinal du logement 8, la goupille 9 traversant ainsi ce logement.The hinge pin 7 is held captive in its housing 8 by a pin 9 removably fixed in a bore 10 of the cap member 2 and made perpendicularly to the longitudinal axis of the housing 8, the pin 9 thus passing through this housing .

La goupille 9 exerce sur une extrémité de l'axe 7 un effort axial tel que l'extrémité opposée de l'axe 7 comprime un ressort hélicoïdal de compression 11 entre cette extrémité et le fond 8a du logement 8.The pin 9 exerts on one end of the axis 7 an axial force such that the opposite end of the axis 7 compresses a helical compression spring 11 between this end and the bottom 8a of the housing 8.

La goupille 9 fait en partie saillie de la face supérieure de la rive d'articulation de l'élément de couronnement 2 de manière à pouvoir la saisir et la retirer manuellement de cet élément.The pin 9 is partly projecting from the upper face of the hinge flange of the cap member 2 so that it can be grasped and removed manually from this element.

De préférence, le logement 8 et le perçage 10 de l'élément de couronnement 2 viennent de fonderie.Preferably, the housing 8 and the piercing 10 of the cap member 2 come from casting.

La goupille 9 maintenant de façon imperdable l'axe d'articulation 7 dans le logement 8 de l'élément de couronnement 2, ce dernier peut être stocké et/ou manipulé sans risque de perte de l'axe d'articulation 7.The pin 9 now captively the hinge pin 7 in the housing 8 of the cap member 2, the latter can be stored and / or manipulated without risk of loss of the hinge pin 7.

L'extrémité de la rive d'articulation 3 de l'élément de couronnement 2 et opposée à celle comportant l'axe d'articulation 7 captif dans son logement 8, est articulée de façon classique au cadre 1 par un axe d'articulation solidaire coaxialement à l'axe 7 soit de cette extrémité de rive d'articulation 3, soit de la rive correspondante du cadre 1, cet axe pouvant s'engager librement lors du montage de l'élément de couronnement 2 sur le cadre 1 dans une gâche de la rive du cadre 1 ou de l'extrémité de la rive d'articulation 3 de l'élément 2.The end of the articulation flange 3 of the crown member 2 and opposite that comprising the hinge pin 7 captive in its housing 8, is articulated in a conventional manner to the frame 1 by an integral hinge pin coaxially with the axis 7 is this end of joint flange 3, or the corresponding side of the frame 1, this axis can engage freely during assembly of the cap member 2 on the frame 1 in a waste the edge of the frame 1 or the end of the hinge side 3 of the element 2.

Le montage de l'articulation de l'élément de couronnement 2 au cadre 1 ressort déjà de la description qui précède et va être maintenant expliqué.The assembly of the articulation of the cap element 2 to the frame 1 is already apparent from the foregoing description and will now be explained.

Tout d'abord, un opérateur saisit l'élément de couronnement 2 pour le poser sur le cadre 1 en introduisant l'axe d'articulation de l'élément 2, opposé à l'axe d'articulation captif 7, dans la gâche correspondante du cadre 1 ou de l'extrémité de la rive d'articulation 3, puis pose l'élément 2 complètement en appui dans la feuillure 5 du cadre 1 comme représenté en figure 1.Firstly, an operator grasps the crown member 2 to place it on the frame 1 by introducing the axis of articulation of the element 2, opposite to the captive articulation axis 7, in the corresponding striker of the frame 1 or the end of the articulation flange 3, then places the element 2 completely in support in the rabbet 5 of the frame 1 as shown in FIG. figure 1 .

Ensuite, l'opérateur retire manuellement, si nécessaire à l'aide d'un outil, la goupille 9 de l'élément de couronnement 2 de façon à libérer l'axe 7 qui, sous l'action de la force de rappel du ressort 11, sort en partie du logement 8 pour s'engager automatiquement dans une gâche correspondante 12 du cadre 1, la gâche 12 pouvant être constituée par un trou borgne.Then, the operator manually removes, if necessary using a tool, the pin 9 of the cap member 2 so as to release the pin 7 which, under the action of the spring restoring force 11, partially out of the housing 8 to engage automatically in a corresponding keeper 12 of the frame 1, the striker 12 may be constituted by a blind hole.

De la sorte, l'articulation de l'élément de couronnement 2 à son cadre 1 est rendue indémontable pour empêcher l'extraction de l'élément 2 de ce cadre.In this way, the articulation of the cap element 2 to its frame 1 is made indémontable to prevent the extraction of the element 2 of this frame.

Le dispositif de l'invention est d'une conception très simple et peu coûteuse puisqu'il utilise des composants du commerce.The device of the invention is of a very simple and inexpensive design since it uses commercial components.
