La présente invention concerne un dispositif de fermeture d'une ouverture, comprenant un cadre et au moins un panneau articulé, du type de ceux qui constituent des équipements de voirie donnant accès par exemple à des regards enterrés dans le sol.The present invention relates to a device for closing an opening, comprising a frame and at least one articulated panel, of the type of those which constitute road equipment giving access for example to manholes buried in the ground.

On connaît un tel dispositif selon lequel les moyens d'articulation indémontables du panneau relativement au cadre comprennent un tenon en saillie à la périphérie du panneau et adapté pour s'engager dans un logement ménagé dans une jupe du cadre et un axe de pivotement s'étendant transversalement dans le tenon du panneau et le logement du cadre pour permettre au panneau de pivoter entre une position abaissée de fermeture du cadre et une position relevée d'accès à l'ouverture du cadre.Such a device is known according to which the indemountable articulation means of the panel relative to the frame comprise a projecting lug at the periphery of the panel and adapted to engage in a housing formed in a skirt of the frame and a pivot axis s'. extending transversely in the tongue of the panel and the housing of the frame to allow the panel to pivot between a lowered position of closure of the frame and a raised position of access to the opening of the frame.

Un tel dispositif selon le préambule de la revendication 1 est connu par le document GB 2390629 A .Such a device according to the preamble of claim 1 is known from the document GB 2390629 A .

Le cadre est scellé dans le sol, à l'extrémité supérieure du regard de visite, par du béton noyant la semelle du cadre.The frame is sealed in the ground, at the upper end of the manhole, with concrete drowning the sole of the frame.

L'axe de pivotement ou d'articulation du panneau au cadre est généralement constitué par un boulon traversant les deux parois latérales du logement du cadre et le tenon du panneau engagé dans ce logement, la tête et l'écrou de fixation du boulon étant serrés en appui respectivement sur les faces externes des deux parois latérales du logement du cadre.The axis of pivoting or articulation of the panel to the frame is generally constituted by a bolt passing through the two side walls of the frame housing and the tenon of the panel engaged in this housing, the bolt head and the fastening nut being tightened. in support respectively on the outer faces of the two side walls of the frame housing.

De tels moyens d'articulation posent un problème lors de l'installation du panneau au cadre.Such articulation means pose a problem when installing the panel to the frame.

En effet, pour permettre l'engagement du boulon d'articulation au travers des parois latérales du logement du cadre et du tenon du panneau engagé dans ce logement, il est nécessaire au préalable de casser la partie de béton de scellement de la semelle du cadre entourant les parois latérales du logement puis, une fois le boulon d'articulation installé, de remplir à nouveau de béton la partie dégagée autour de l'ouverture du cadre.Indeed, to allow the engagement of the articulation bolt through the side walls of the frame housing and the tenon of the panel engaged in this housing, it is necessary first to break the concrete part of the footing of the frame surrounding the side walls of the housing then, once the bolt of articulated installed, to fill again with concrete the part released around the opening of the frame.

La présente invention a pour but de résoudre le problème ci-dessus des dispositifs de fermeture connus.The present invention aims to solve the above problem of known closure devices.

A cet effet, selon l'invention, le dispositif de fermeture pour regard de chaussée, comprenant un cadre, au moins un panneau adapté pour être porté par le cadre et des moyens d'articulation indémontables du panneau relativement au cadre, les moyens d'articulation comprenant un tenon en saillie à la périphérie du panneau et adapté pour s'engager dans un logement ménagé dans une jupe du cadre et un axe de pivotement s'étendant transversalement dans le tenon du panneau et le logement du cadre, est caractérisé en ce que l'axe de pivotement comprend une broche constituée d'au moins deux parties montées télescopiquement l'une dans l'autre et axialement écartées l'une de l'autre par un ressort disposé entre les deux parties télescopiques de manière à engager et maintenir les deux extrémités de la broche de pivotement respectivement dans deux trous borgnes du cadre.For this purpose, according to the invention, the closing device for manhole, comprising a frame, at least one panel adapted to be carried by the frame and the panel of the releasable hinge means relative to the frame, the means of articulation comprising a projecting lug at the periphery of the panel and adapted to engage in a housing formed in a skirt of the frame and a pivot axis extending transversely in the tongue of the panel and the housing of the frame, is characterized in that that the pivot axis comprises a pin consisting of at least two parts mounted telescopically one in the other and axially spaced apart from each other by a spring disposed between the two telescopic parts so as to engage and maintain both ends of the pivot pin respectively in two blind holes of the frame.

Avantageusement, les deux trous borgnes sont formés respectivement dans deux parois latérales délimitant le logement du tenon du panneau.Advantageously, the two blind holes are respectively formed in two side walls delimiting the housing of the tenon of the panel.

Avant mise en place des moyens d'articulation dans le logement du cadre, les deux parties télescopiques de la broche sont maintenues à une position rentrée ou enfoncée coaxialement l'une dans l'autre à l'encontre de la force de rappel du ressort par une goupille traversant les deux parties télescopiques et pouvant être retirée lorsque le tenon du panneau muni de la broche est engagé dans le logement du cadre de manière que les deux parties télescopiques puissent s'écarter axialement l'une de l'autre par l'action du ressort pour engager leurs extrémités dans les deux trous borgnes du cadre.Before placing the hinge means in the housing of the frame, the two telescopic parts of the spindle are held in a retracted position or pushed coaxially into each other against the return force of the spring by a pin passing through the two telescopic parts and removable when the tenon of the panel provided with the pin is engaged in the housing of the frame so that the two telescopic parts can move axially away from each other by the action spring to engage their ends in the two blind holes of the frame.

Le tenon du panneau comprend au moins une partie évidée suivant sa largeur pour permettre l'introduction de la broche, dont les parties télescopiques sont rentrées l'une dans l'autre, dans le tenon suivant une direction transversale à ce dernier.The tenon of the panel comprises at least one recessed portion along its width to allow the introduction of the pin, the telescopic parts are retracted into one another in the post in a direction transverse thereto.

La goupille de retenue des deux parties télescopiques de la broche fait saillie de la partie évidée du tenon.The retaining pin of the two telescopic parts of the spindle protrudes from the recessed portion of the post.

Le ressort est avantageusement un ressort hélicoïdal de compression logé dans la partie tubulaire externe des deux parties télescopiques et dont une spire d'extrémité est en appui au fond de la partie tubulaire et la spire d'extrémité opposée est en appui sur l'extrémité de la partie télescopiquement interne.The spring is advantageously a helical compression spring housed in the outer tubular part of the two telescopic parts and an end turn of which bears against the bottom of the tubular part and the opposite end turn bears on the end of the tubular part. the telescopically internal part.

L'invention vise également une broche destinée à former une articulation indémontable entre un panneau et un cadre de support du panneau par un regard de chaussée et qui est caractérisée en ce qu'elle comprend deux parties montées télescopiquement l'une dans l'autre et occupant une position rentrée l'une dans l'autre à l'encontre de la force de rappel d'un ressort hélicoïdal de compression disposé entre les deux parties télescopiques qui sont maintenues à cette position par une goupille traversant les deux parties télescopiques.The invention also relates to a pin intended to form an indémontable joint between a panel and a support frame of the panel by a manhole and which is characterized in that it comprises two parts mounted telescopically one in the other and occupying a retracted position against each other against the biasing force of a helical compression spring disposed between the two telescopic parts which are held at this position by a pin passing through the two telescopic parts.

L'invention vise enfin un procédé d'installation d'un panneau, tel qu'un tampon ou une grille, à montage articulé et indémontable sur un cadre de support, tel que défini précédemment, et qui est caractérisé en ce qu'il consiste à loger la broche, dont les deux parties télescopiques sont maintenues en position rentrées l'une dans l'autre par la goupille, dans le tenon au travers de celui-ci, engager le tenon et la broche dans le logement du cadre et retirer la goupille de manière que le ressort écarte axialement l'une de l'autre les deux parties télescopiques pour engager leurs extrémités respectivement dans les deux trous borgnes du cadre.The invention finally relates to a method of installing a panel, such as a pad or a grid, articulated and releasable mounting on a support frame, as defined above, and which is characterized in that it consists to accommodate the spindle, the two telescopic parts of which are held in the retracted position by the pin, in the tenon therethrough, engage the pin and the spindle in the housing of the frame and remove the pin so that the spring axially apart from each other the two telescopic parts to engage their ends respectively in the two blind holes of the frame.

Le tenon 6 du panneau 2 et le logement 7 présentent respectivement deux formes approximativement en T complémentaires l'une de l'autre, mais il est bien entendu que cette forme n'est pas limitative.The post 6 of the panel 2 and the housing 7 respectively have two approximately T-shaped shapes complementary to each other, but it is understood that this form is not limiting.

Ainsi, le tenon 6 comporte une partie 11 s'étendant radialement du panneau 2 et correspondant à la jambe du T et une partie de forme générale cylindrique 12 correspondant à la barre transversale du T. La partie transversale 12 a une longueur quelque peu inférieure à la distance entre les deux faces internes opposées des deux parois latérales 9 du logement 7.Thus, the tenon 6 comprises a portion 11 extending radially from the panel 2 and corresponding to the leg of the T and a portion of generally cylindrical shape 12 corresponding to the transverse bar T. The transverse portion 12 has a length somewhat less than the distance between the two opposite internal faces of the two lateral walls 9 of the housing 7.

Selon l'invention, l'axe d'articulation 8 est constitué par une broche cylindrique comprenant deux parties engagées télescopiquement l'une dans l'autre respectivement une partie externe tubulaire 13 et une partie interne 14 pouvant coulisser coaxialement dans la partie 13 de manière à s'écarter axialement de la partie 13 sous l'action d'un ressort hélicoïdal de compression 15 logé dans la partie 13 en ayant l'une de ses spires d'extrémité en appui sur une paroi de fond 16 de la partie tubulaire 13 et sa spire d'extrémité opposée en appui sur l'extrémité de la partie coulissante 14 logée dans la partie 13 de la broche 8.According to the invention, the hinge pin 8 is constituted by a cylindrical pin comprising two parts telescopically engaged in each other respectively a tubular outer portion 13 and an inner portion 14 slidable coaxially in the portion 13 so to depart axially from the portion 13 under the action of a helical compression spring 15 housed in the portion 13 having one of its end turns bearing on a bottom wall 16 of the tubular portion 13 and its opposite end turn bearing on the end of the sliding portion 14 housed in the portion 13 of the pin 8.

La partie coulissante 14 de la broche 8 se termine à l'opposé de son extrémité en contact avec le ressort 15 par une partie de plus grand diamètre 14a sensiblement égal au diamètre externe de la partie tubulaire 13.The sliding portion 14 of the pin 8 terminates opposite its end in contact with the spring 15 by a portion of larger diameter 14a substantially equal to the outer diameter of the tubular portion 13.

En position inactive de la broche 8, la partie coulissante 14 est enfoncée dans la partie tubulaire 13 en comprimant le ressort 15 et est maintenue à cette position par une goupille 17 traversant les deux parties 13, 14 de la broche 8. A cette position d'enfoncement de la partie 14 dans la partie 13, la partie de plus grand diamètre 14a de la partie 14 est en appui sur l'extrémité correspondante de la partie tubulaire 13.In the idle position of the pin 8, the sliding portion 14 is pressed into the tubular portion 13 by compressing the spring 15 and is held at this position by a pin 17 passing through the two parts 13, 14 of the pin 8. At this position d of the portion 14 in the portion 13, the portion of larger diameter 14a of the portion 14 bears against the corresponding end of the tubular portion 13.

Comme cela ressort mieux de la figure 2, la partie cylindrique 12 du tenon 6 est partiellement évidée comme indiqué en 18 suivant sa direction longitudinale, c'est-à-dire transversale à la largeur du tenon 6, de manière à former une fenêtre dans laquelle peut être engagée la broche 8 dont les deux parties 13, 14 sont maintenues enfoncées l'une dans l'autre par la goupille 17. A cette position enfoncée l'une dans l'autre des parties 13, 14, la broche 8 présente une longueur sensiblement égale à la longueur de la partie cylindrique 12 du tenon 6 dont le perçage traversant 12a a un diamètre légèrement supérieur au diamètre externe de la partie tubulaire 13 de la broche 8.As it stands out better from figure 2 , the cylindrical portion 12 of the post 6 is partially recessed as indicated at 18 in its longitudinal direction, that is to say transverse to the width of the post 6, so as to form a window in which can be engaged pin 8 which the two parts 13, 14 are held pressed into each other by the pin 17. In this position pushed into each other of the parts 13, 14, the pin 8 has a length substantially equal to the length of the cylindrical portion 12 of the pin 6, the through bore 12a has a diameter slightly greater than the outer diameter of the tubular portion 13 of the pin 8.

L'installation de la charnière d'articulation reliant le panneau 2 au cadre 1 s'effectue comme suit.The installation of the hinge hinge connecting the panel 2 to the frame 1 is as follows.

Tout d'abord, la broche 8, dont les deux parties 13, 14 sont maintenues enfoncées l'une dans l'autre par la goupille 17, est introduite dans le trou traversant 12a de la partie cylindrique 12 du tenon 6 au travers de la partie évidée 18 de manière que les extrémités libres de la broche 8 ne fassent pas saillie de part et d'autre du tenon 6.Firstly, the pin 8, the two parts 13, 14 of which are held down one inside the other by the pin 17, is introduced into the through hole 12a of the cylindrical portion 12 of the post 6 through the recessed portion 18 so that the free ends of the pin 8 do not protrude either side of the post 6.

Ensuite, le panneau 2 est présenté relativement au cadre 1 à une position relevée et le tenon 6 est engagé dans le logement 7 du cadre 1. Le maintien du panneau 2 à la position relevée relativement au cadre 1 peut être assuré par deux ergots 19 axialement espacés faisant radialement saillie de la partie cylindrique 12 du tenon 6 et venant en butée sur des surfaces d'appui respectives du cadre 1, comme cela est connu en soi.Then, the panel 2 is presented relative to the frame 1 at a raised position and the post 6 is engaged in the housing 7 of the frame 1. The maintenance of the panel 2 in the raised position relative to the frame 1 can be provided by two lugs 19 axially spaced radially projecting from the cylindrical portion 12 of the pin 6 and coming into abutment on respective bearing surfaces of the frame 1, as is known per se.

Ensuite, la goupille 17 est retirée de la broche 8 et le ressort 15 exerce sur la partie 14 un effort la faisant coulisser dans un sens l'écartant de la partie 13 de manière que les deux extrémités libres 13a et 14a des parties 13 et 14 de la broche 8 puissent s'engager respectivement dans deux trous borgnes coaxiaux 20 formés dans les deux parois latérales 9 du logement 7. De la sorte, la broche 8 est maintenue captive dans le logement 7 en étant pratiquement invisible de l'extérieur du fait que le tenon 6 est logé dans le logement 7 suivant un jeu très faible.Then, the pin 17 is withdrawn from the pin 8 and the spring 15 exerts on the part 14 a force sliding it in a direction away from the part 13 so that the two free ends 13a and 14a of the parts 13 and 14 pin 8 can respectively engage two coaxial blind holes 20 formed in the two side walls 9 of the housing 7. In this way, the pin 8 is held captive in the housing 7 being virtually invisible from the outside of the fact that the stud 6 is housed in the housing 7 in a very weak game.

Ainsi, la mise en place des moyens d'articulation de l'invention reliant le panneau 2 au cadre 1 peut s'effectuer sans casser le matériau, tel que béton, scellant la semelle 5 du cadre 1 dans le sol en entourant les parois latérales 9 du logement 7 puisque les extrémités de la broche 8 peuvent être logées dans les deux trous borgnes 20 formés dans ces deux parois latérales 9.Thus, the establishment of the articulation means of the invention connecting the panel 2 to the frame 1 can be performed without breaking the material, such as concrete, sealing the sole 5 of the frame 1 in the soil surrounding the side walls 9 of the housing 7 since the ends of the pin 8 can be accommodated in the two blind holes 20 formed in these two side walls 9.

Bien entendu, l'invention peut s'appliquer à un équipement de voirie comportant plusieurs panneaux, chacun monté articulé au cadre par les moyens d'articulation ci-dessus décrits. Bien que cela soit plus compliqué du point de vue structure, la broche pourrait être constituée de trois parties, une partie centrale tubulaire et deux parties opposées montées coulissantes respectivement dans les deux parties d'extrémité de la partie centrale avec interposition d'un ressort entre les deux parties coulissantes qui sont, en position inactive de la broche, enfoncées dans la partie tubulaire centrale et retenues dans cette position par deux goupilles accessibles de l'extérieur, l'une traversant la partie tubulaire centrale et l'une des parties coulissantes tandis que l'autre traverse la partie centrale et l'autre partie d'extrémité coulissante. En retirant les deux goupilles, les deux parties d'extrémité coulissante s'écartent l'une de l'autre pour s'engager dans les deux trous borgnes des deux parois latérales délimitant le logement 7 du tenon 6 du panneau.Of course, the invention can be applied to road equipment comprising several panels, each mounted hinged to the frame by the hinge means described above. Although it is more complicated from a structural point of view, the spindle could consist of three parts, a tubular central part and two opposite parts mounted respectively sliding in the two end parts of the central part with interposition of a spring between the two sliding parts which are, in the inactive position of the pin, driven into the central tubular part and retained in this position by two pins accessible from the outside, one passing through the central tubular part and one of the sliding parts while that the other crosses the central portion and the other sliding end portion. By removing the two pins, the two sliding end portions move away from each other to engage the two blind holes of the two side walls defining the housing 7 of the post 6 of the panel.
