Description

La présente invention concerne d'une manière générale les regards de chaussée.The present invention relates generally to manholes.

Un regard de chaussée comprend un cadre enfoui dans le sol ou la chaussée, un couvercle pouvant occuper une position de fermeture de l'ouverture du cadre et à laquelle le couvercle s'inscrit dans ce cadre en étant en appui sur une nervure périphérique d'assise solidaire du cadre en faisant saillie dans l'ouverture de ce dernier.A manhole comprises a frame buried in the ground or the roadway, a cover that can occupy a closed position of the opening of the frame and to which the cover fits into this frame while being supported on a peripheral rib of seat secured to the frame projecting into the opening of the latter.

Ce genre de regard (par exemple décrit dans le document WO2010/106266A1 ) est ainsi du type selon lequel le couvercle repose en appui sur la nervure périphérique d'assise du cadre sans être articulé à ce dernier.This kind of look (for example described in the document WO2010 / 106266A1 ) is thus of the type in which the cover rests on the peripheral rib of the frame without being articulated to the latter.

Le cadre d'un tel regard peut être rectangulaire et le couvercle peut être constitué par un ou plusieurs vantaux, par exemple de forme rectangulaire, s'inscrivant dans le cadre en position de fermeture de ce dernier ou par au moins deux vantaux en forme de triangles rectangles s'inscrivant dans le cadre rectangulaire en étant juxtaposés les uns par rapport aux autres à leur position de fermeture de ce cadre.The frame of such a look can be rectangular and the cover can be constituted by one or more leaves, for example of rectangular shape, forming part of the frame in the closed position of the latter or by at least two leaves in the form of right triangles forming part of the rectangular frame being juxtaposed with each other at their closed position of this frame.

Dans certaines circonstances, il peut être nécessaire de remplacer l'ensemble du regard de chaussée à cadre et couvercle par un ensemble selon lequel le couvercle est monté articulé au côté correspondant du cadre pour faciliter l'accès au regard de chaussée au travers de l'ouverture du cadre.In certain circumstances, it may be necessary to replace the entire frame and cover view by an assembly in which the cover is hinged to the corresponding side of the frame to facilitate access to the manhole through the opening of the frame.

A cet effet, il est alors nécessaire de desceller le cadre du sol pour le remplacer par un cadre muni d'éléments d'articulation auxquels seront accouplés des éléments d'articulation du couvercle pour permettre à ce dernier de pivoter entre ses deux positions abaissée de fermeture du cadre et relevée d'ouverture de ce cadre.For this purpose, it is then necessary to unseal the frame of the ground to replace it with a frame provided with hinge elements to which will be coupled hinge elements of the lid to allow the latter to rotate between its two positions lowered from closing the frame and opening statement of this frame.

Une telle solution nécessite de la main d'oeuvre à la fois pour desceller le cadre du sol et sceller dans le sol le nouveau cadre pourvu de ces éléments d'articulation et est également coûteuse, non seulement en raison de la main d'oeuvre, mais également de l'utilisation d'un nouveau cadre à éléments d'articulation. Cette solution a également pour inconvénient qu'elle bloque la chaussée de manière prolongée à cause du temps de prise du mortier de scellement du nouveau cadre dans la chaussée.Such a solution requires labor at a time to unseal the frame of the ground and seal in the ground the new frame provided with these hinge elements and is also expensive, not only because of the manpower, but also the use of a new frame with hinge elements. This solution also has the disadvantage that it blocks the roadway for a long time because of the setting time of the sealing mortar of the new frame in the roadway.

La présente invention a pour but de pallier les inconvénients ci-dessus en proposant une solution permettant de transformer un cadre non pourvu à l'origine d'éléments d'articulation en un cadre apte à recevoir de manière articulée un couvercle d'obturation de ce cadre.The present invention aims to overcome the above drawbacks by proposing a solution for transforming a frame not originally provided. hinge elements in a frame adapted to receive in a hinged manner a closure cover of this frame.

A cet effet, selon l'invention, l'ensemble pour regard de chaussée comprenant un cadre, un couvercle pouvant occuper une position de fermeture de l'ouverture du cadre en appui sur au moins deux faces d'assise solidaires du cadre en faisant saillie dans l'ouverture de ce dernier, est caractérisé en ce que le cadre comprend une pièce rapportée sur l'une des deux faces d'assise et qui est pourvue d'au moins un élément d'articulation pouvant être accouplé à un élément d'articulation correspondant du couvercle pour permettre à ce dernier d'être articulé à la pièce rapportée.For this purpose, according to the invention, the assembly for a manhole comprising a frame, a cover that can occupy a closed position of the opening of the frame resting on at least two integral seat surfaces of the frame projecting in the opening of the latter, is characterized in that the frame comprises an insert on one of the two faces of the seat and which is provided with at least one hinge element that can be coupled to an element of corresponding hinge of the cover to allow the latter to be articulated to the insert.

Selon une variante de réalisation, la pièce rapportée est amoviblement fixée à la face d'assise du cadre par des vis de fixation.According to an alternative embodiment, the insert is removably attached to the seat face of the frame by fixing screws.

Selon d'autres variantes de réalisation, la pièce rapportée est fixée par soudage, collage, clouage ou chevillage à la face d'assise du cadre.According to other embodiments, the insert is fixed by welding, gluing, nailing or pegging to the seat face of the frame.

La pièce rapportée comprend en outre un autre élément d'articulation d'une extrémité d'une jambe de maintien du couvercle à sa position d'ouverture.The insert further comprises another hinge member of an end of a holding leg of the lid to its open position.

La pièce rapportée comprend également un autre élément d'articulation pouvant être accouplé à un élément d'articulation d'extrémité d'un vérin d'assistance à l'ouverture du cadre.The insert also includes another hinge member that can be coupled to an end hinge member of a support cylinder opening the frame.

De préférence, la pièce rapportée est en forme de cornière dont l'une des ailes, qui est en appui et fixée sur la face d'assise du cadre, comprend au moins l'élément d'articulation pouvant être accouplé à l'élément d'articulation correspondant du couvercle et l'autre aile située dans l'ouverture du cadre comprend chaque autre élément d'articulation pouvant être accouplé à l'élément d'articulation d'extrémité du vérin d'assistance et à l'extrémité de la jambe de maintien.Preferably, the insert is shaped angle whose one of the wings, which is supported and fixed on the frame face of the frame, comprises at least the hinge element can be coupled to the element d corresponding hinge of the lid and the other wing located in the opening of the frame comprises each other hinge element which can be coupled to the end hinge member of the assistance cylinder and to the end of the leg keeping.

L'aile de la pièce rapportée en forme de cornière est fixée sur la face d'assise du cadre par les vis de fixation traversant des trous de préférence oblongs perpendiculaires au côté correspondant du cadre et ancrées dans des trous taraudés de cette face d'assise.The wing of the insert-shaped angle is fixed on the seat face of the frame by the fastening screws passing through preferably oblong holes perpendicular to the corresponding side of the frame and anchored in threaded holes of the seat face .

Le couvercle comprend un ou plusieurs vantaux, chacun de forme rectangulaire ou en forme de triangle rectangle, pouvant s'inscrire dans le cadre de forme rectangulaire, chaque vantail comportant à sa face interne au moins l'élément d'articulation situé au voisinage du bord rectiligne correspondant du vantail et pouvant être accouplé à l'élément d'articulation de la pièce rapportée fixé à la partie rectiligne correspondante de la face d'assise s'étendant le long de la paroi correspondante du cadre.The cover comprises one or more leaves, each of rectangular shape or in the shape of a right triangle, which can be part of the rectangular frame, each leaf having at its inner face at least the hinge element located in the vicinity of the corresponding straight edge of the leaf and can be coupled to the hinge element of the insert attached to the corresponding rectilinear portion of the seat face extending along the wall corresponding frame.

Avantageusement, les éléments d'articulation sont constitués par des chapes pouvant être accouplées les unes aux autres par des axes d'articulation.Advantageously, the hinge elements consist of clevises that can be coupled to each other by hinge pins.

L'invention vise également un regard de chaussée, qui est caractérisé en ce qu'il comprend un ensemble tel que défini précédemment.The invention also relates to a manhole, which is characterized in that it comprises an assembly as defined above.

L'invention va être décrite en référence à un regard de chaussée dont le cadre présente une forme générale rectangulaire et le couvercle d'obturation de l'ouverture de ce cadre est constitué par deux plaques ou vantaux rectangulaires, mais il est bien entendu qu'elle peut s'appliquer également à un cadre rectangulaire dont le couvercle est constitué par au moins deux vantaux présentant chacun la forme d'un triangle rectangle et juxtaposés l'un à l'autre en position de fermeture de l'ouverture de ce cadre en s'inscrivant dans celui-ci. L'invention peut également s'appliquer à un cadre pré-scellé à un seul vantail de couvercle ou à plus de deux vantaux de couvercle, selon les dimensions de l'ouverture du cadre.The invention will be described with reference to a manhole whose frame has a generally rectangular shape and the closure cover of the opening of this frame is constituted by two rectangular plates or leaves, but it is understood that it can also be applied to a rectangular frame whose cover is constituted by at least two leaves each having the shape of a right triangle and juxtaposed one to the other in the closed position of the opening of this frame. registering in this one. The invention can also be applied to a pre-sealed frame with a single door leaf or more than two door leaves, depending on the dimensions of the opening of the frame.

En se reportant aux figures, la référence 1 désigne un regard de chaussée comprenant une cheminée de visite 2 enfouie dans le sol et un ensemble à cadre rectangulaire 3 et couvercle 4 pouvant occuper une position abaissée d'obturation de l'ouverture O du cadre 3 en s'inscrivant dans celui-ci comme représenté en figure 1.Referring to the figures, the reference 1 designates a manhole comprising a visit chimney 2 buried in the ground and a rectangular frame assembly 3 and cover 4 can occupy a lowered position of closing the opening O of the frame 3 by registering in it as represented in figure 1 .

Le cadre 3 est disposé sur la cheminée de visite et est également enfoui ou scellé dans le sol ou la chaussée de manière que son bord périphérique supérieur soit en affleurement avec le sol ou la chaussée.The frame 3 is disposed on the inspection chimney and is also buried or sealed in the ground or pavement so that its upper peripheral edge is flush with the ground or the roadway.

Le cadre 3 comprend quatre parois latérales 5 qui sont assemblées les unes aux autres par des boulons de fixation 6 et deux des parois latérales parallèles sont constituées par deux parties de paroi 5a assemblées bout à bout par des boulons de fixation, non représentés.The frame 3 comprises four side walls 5 which are joined to each other by fixing bolts 6 and two of the parallel side walls are constituted by two wall portions 5a assembled end to end by fixing bolts, not shown.

Dans la présente description, le cadre 3 est réalisé en plusieurs éléments de fonderie assemblés entre eux.In the present description, the frame 3 is made of several foundry elements assembled together.

Cependant, le cadre 3 peut également être réalisé en un seul bloc venant de fonderie, en plusieurs éléments venant de fonderie assemblés entre eux par soudage ou encore en acier mécano-soudé.However, the frame 3 can also be made in one block from the foundry, in several elements from the foundry assembled together by welding or welded steel.

Le couvercle 4 est constitué par deux vantaux rectangulaires 7 disposés côte à côte en s'inscrivant dans le cadre 3 à leur position d'obturation de l'ouverture O de ce cadre.The cover 4 is constituted by two rectangular leaves 7 arranged side by side by registering in the frame 3 at their closed position of the opening O of this frame.

Le cadre 3 comprend deux faces internes 8 solidaires de deux des parois latérales parallèles 5 du cadre 3 en faisant saillie dans l'ouverture O de ce dernier et servant d'assise aux deux vantaux 7 lorsqu'ils occupent leur position d'obturation de l'ouverture O du cadre 3.The frame 3 comprises two internal faces 8 secured to two of the parallel side walls 5 of the frame 3 protruding into the opening O of the latter and serving as a seat for the two leaves 7 when they are in their closed position. O opening of the frame 3.

Comme cela ressort des figures, chacune des faces d'assise 8 peut être constituée par deux faces supérieures rectilignes 10 dans un même plan d'un tronçon généralement parallélépipédique 11 de chacune des deux parois parallèles 5 constituées par les deux parties de paroi latérale bout à bout 5a, chaque partie de paroi latérale 5a comportant un demi tronçon 11a. Bien entendu, dans le cas d'un cadre 3 en une seule pièce, chaque face d'assise 8 ne comportera qu'une seule face supérieure 10 de chacune des deux parois parallèles 5 de ce cadre et s'étendant le long de chaque paroi 5.As can be seen from the figures, each of the seat faces 8 may consist of two rectilinear upper faces 10 in one and the same plane of a generally parallelepipedic section 11 of each of the two parallel walls constituted by the two end-to-end sidewall portions. end 5a, each side wall portion 5a having a half-section 11a. Of course, in the case of a frame 3 in one piece, each seat face 8 will have only one upper face 10 of each of the two parallel walls 5 of this frame and extending along each wall 5.

Un dispositif 12 est prévu pour verrouiller les deux vantaux 7 à leur position d'obturation de l'ouverture O du cadre 3.A device 12 is provided for locking the two leaves 7 in their closed position of the opening O of the frame 3.

Le dispositif de verrouillage 12 comprend un pêne 13 solidaire de l'un des vantaux 7 et coopérant avec une gâche 14 de l'une des parois 5 du cadre 3, par exemple l'une des parties 5a de la paroi correspondante 5, lequel pêne 13 peut être manoeuvré par un outil 15 traversant un orifice 16 du vantail 7 pour désengager le pêne 13 de la gâche 14 à l'encontre de la force de rappel d'un ressort hélicoïdal 17 monté concentriquement sur le pêne 13.The locking device 12 comprises a bolt 13 integral with one of the leaves 7 and cooperating with a keeper 14 of one of the walls 5 of the frame 3, for example one of the parts 5a of the corresponding wall 5, which bolt 13 can be operated by a tool 15 through an orifice 16 of the leaf 7 to disengage the latch 13 of the latch 14 against the return force of a coil spring 17 mounted concentrically on the bolt 13.

Un tel dispositif de verrouillage est déjà connu en soi et n'a pas à être davantage détaillé. En outre, d'autres types de dispositifs de verrouillage connus en soi peuvent être utilisés.Such a locking device is already known per se and does not have to be more detailed. In addition, other types of locking devices known per se can be used.

L'autre vantail 7, qui ne comporte pas le dispositif de verrouillage 12, comporte à son côté destiné à être juxtaposé au côté correspondant du vantail 7 à dispositif de verrouillage 12 en position d'obturation de l'ouverture O du cadre 3, une patte 18 venant sous le vantail 7 à dispositif de verrouillage 12 pour empêcher le soulèvement du vantail 7 à patte 18 lorsque l'autre vantail 7 est verrouillé au cadre 3 par le dispositif de verrouillage 12. Cependant, au lieu de constituer un vantail maître 7 verrouillé au cadre 3 et un vantail esclave 7, les vantaux 7 peuvent être verrouillés au cadre 3 indépendamment les uns des autres.The other leaf 7, which does not include the locking device 12, comprises at its side intended to be juxtaposed to the corresponding side of the leaf 7 to locking device 12 in the closed position of the opening O of the frame 3, a tab 18 coming under the leaf 7 with locking device 12 to prevent the lifting of leaf 7 with tab 18 when the other leaf 7 is locked to the frame 3 by the locking device 12. However, instead of constituting a master leaf 7 locked to the frame 3 and a slave leaf 7, the leaves 7 can be locked to the frame 3 independently of each other.

Chaque vantail 7 est également pourvu à la face supérieure de son voile d'au moins un axe 19 accessible de l'extérieur et logé au-dessus d'une excavation 20 du vantail pour permettre l'introduction d'une extrémité en crochet d'un outil 21 permettant de retirer chaque vantail 7 du cadre 3 une fois le dispositif de déverrouillage 12 déverrouillé.Each leaf 7 is also provided at the upper face of its web with at least one axis 19 accessible from the outside and housed above an excavation 20 of the leaf to allow the introduction of a hook end of a tool 21 for removing each leaf 7 of the frame 3 once the unlocking device 12 unlocked.

Comme expliqué au début de la présente description, il peut s'avérer nécessaire de monter de manière articulée deux vantaux 7 au cadre 3 prévu à l'origine pour recevoir des vantaux simplement posés sur les faces d'assise opposées 10.As explained at the beginning of the present description, it may be necessary to hingeably mount two leaves 7 to the frame 3 originally provided to receive leaves simply placed on the opposite seating faces 10.

La présente invention propose une solution permettant d'articuler les deux vantaux 7 au cadre 3 sans desceller le cadre 3 de la chaussée et, par conséquent, en conservant tel quel ce cadre.The present invention proposes a solution for articulating the two leaves 7 to the frame 3 without loosening the frame 3 of the road and, therefore, keeping this frame as it is.

A cet effet, selon l'invention, on prévoit une pièce 30, de préférence constituée par une cornière à ailes 31, 32 perpendiculaires l'une à l'autre, et qui est rapportée sur l'une des deux faces d'assise 8 du cadre 3.For this purpose, according to the invention, there is provided a part 30, preferably constituted by a winged angle iron 31, 32 perpendicular to one another, and which is attached to one of the two seat faces 8 of the frame 3.

Comme représenté, la pièce 30 est rapportée sur les deux faces d'assise 10 en prolongement l'une de l'autre des deux parties de paroi 5a de la paroi 5 opposée à la paroi parallèle 5 dont l'une de ses parties 5a comporte la gâche 14 de verrouillage du vantail correspondant 7 au cadre 3.As shown, the part 30 is attached to the two seat faces 10 in extension of one another of the two wall portions 5a of the wall 5 opposite to the parallel wall 5, one of whose parts 5a comprises the latch 14 for locking the leaf corresponding to frame 7 3.

Comme cela ressort mieux de la figure 6, la pièce en cornière 30 comporte sur son aile 31 quatre éléments d'articulation 33 de préférence en forme de chapes, régulièrement espacés le long de l'aile 31 en faisant saillie perpendiculairement de celle-ci.As it stands out better from figure 6 , the corner piece 30 has on its flange 31 four hinge elements 33 preferably shaped screeds, regularly spaced along the wing 31 projecting perpendicularly thereof.

Chaque chape d'articulation 33 comprend deux parois latérales parallèles 34 s'étendant transversalement à la direction longitudinale de l'aile 31 et une paroi ou âme 35 de liaison des deux parois latérales 34 s'étendant parallèlement à la direction longitudinale de l'aile 31 en étant sensiblement en affleurement avec le bord d'extrémité de l'aile 31. Ainsi, chaque chape d'articulation 33 présente en section transversale une forme sensiblement en U.Each articulation clevis 33 comprises two parallel side walls 34 extending transversely to the longitudinal direction of the wing 31 and a connecting wall or core 35 of the two lateral walls 34 extending parallel to the longitudinal direction of the wing 31 being substantially flush with the end edge of the wing 31. Thus, each hinge clevis 33 has a substantially U-shaped cross section.

Les deux parois latérales 34 de chaque chape d'articulation 33 comportent respectivement deux perçages 36 destinés au passage d'un axe d'articulation 37, comme on le verra mieux ultérieurement.The two side walls 34 of each articulation clevis 33 respectively comprise two holes 36 for the passage of a hinge pin 37, as will be seen later.

La pièce en cornière 30 comprend en outre deux chapes d'articulation 38 solidaires de l'autre aile 32 en étant espacées l'une de l'autre le long de cette aile, chaque chape 38 servant d'articulation à un vérin d'assistance comme on le verra ultérieurement. Le nombre de chapes 38 de fixation de vérins peut dépendre du poids des vantaux 7 et du degré d'assistance souhaité.The angle piece 30 further comprises two pivoting yokes 38 integral with the other flange 32 being spaced apart from each other along this flange, each yoke 38 serving as a hinge to an assistance jack as we will see later. The number of yokes 38 for fixing cylinders may depend on the weight of the leaves 7 and the degree of assistance desired.

Chaque chape d'articulation 38 comprend deux parois parallèles 39 solidaires de l'aile 32 perpendiculairement à celle-ci, chaque paroi 39 comportant deux perçages 40 destinés au passage d'un axe d'articulation 41 comme on le verra ultérieurement.Each articulation clevis 38 comprises two parallel walls 39 integral with the flange 32 perpendicular thereto, each wall 39 having two bores 40 for the passage of a hinge axis 41 as will be seen later.

Les chapes d'articulation 33 et 38 sont disposées symétriquement au plan médian transversal de la pièce en cornière 30.The articulation clevises 33 and 38 are arranged symmetrically with the transverse median plane of the angle piece 30.

L'aile 31 de la pièce en cornière 30 comporte plusieurs perçages en forme de trous oblongs 31a, par exemple au nombre de quatre, et s'étendant suivant une direction transversale à la direction longitudinale de l'aile 31.The wing 31 of the angle piece 30 has several holes in the form of oblong holes 31a, for example four in number, and extending in a direction transverse to the longitudinal direction of the wing 31.

Les perçages 31a peuvent également être disposés symétriquement au plan médian transversal de la pièce en cornière 30.The holes 31a may also be arranged symmetrically to the transverse median plane of the angle piece 30.

Les perçages 31a permettent le passage de vis 42 assurant la fixation de l'aile 31 de la pièce en cornière 30 sur les deux faces d'assise 10 des deux parties 5a de la paroi correspondante 5.The holes 31a allow the passage of screws 42 ensuring the attachment of the wing 31 of the corner piece 30 on the two seat faces 10 of the two parts 5a of the corresponding wall 5.

Ainsi, chacune des faces d'assise 10 comprend deux trous taraudés 43 réalisés dans la partie correspondante 11a du tronçon interne 11 de la paroi 5 suivant une direction perpendiculaire à la face d'assise supérieure 10.Thus, each of the seat faces 10 comprises two threaded holes 43 made in the corresponding part 11a of the internal section 11 of the wall 5 in a direction perpendicular to the upper seat face 10.

La longueur de la pièce en cornière 30 est légèrement inférieure à la longueur de la paroi latérale 5 comportant les deux faces d'assise 10 sur lesquelles la pièce en cornière 30 peut être fixée, afin de permettre l'introduction de la pièce en cornière 30 entre les deux autres parois parallèles en un seul bloc 5.The length of the corner piece 30 is slightly less than the length of the side wall 5 having the two seat faces 10 on which the corner piece 30 can be fixed, to allow the introduction of the piece angle 30 between the other two parallel walls in a single block 5.

Ainsi, la pièce en cornière 30 peut être amoviblement fixée aux deux faces d'assise 10 du cadre 3 par les vis de fixation 42.Thus, the corner piece 30 can be removably attached to the two seat faces 10 of the frame 3 by the fixing screws 42.

Selon une variante de réalisation, la pièce en cornière 30 peut être fixée par soudage aux deux faces d'assise 10 du cadre 3, mais elle peut également être fixée par collage, clouage ou chevillage.According to an alternative embodiment, the corner piece 30 can be fixed by welding to the two seat faces 10 of the frame 3, but it can also be fixed by gluing, nailing or pegging.

Chaque vantail 7 comprend deux éléments d'articulation 44, mieux visibles en figure 4, solidaires de la face interne du vantail 7 et pouvant être accouplés respectivement à deux des éléments d'articulation en forme de chapes 33 de la pièce en cornière 30 par l'intermédiaire des axes d'articulation 37 pour permettre au vantail 7 d'être monté articulé au cadre 3.Each leaf 7 comprises two articulation elements 44, better visible in figure 4 , integral with the inner face of the leaf 7 and can be coupled respectively to two of the clevis-shaped hinge elements 33 of the angle piece 30 via the hinge pins 37 to allow the leaf 7 to be mounted articulated to the frame 3.

Chaque élément d'articulation 44 est en forme de chape comprenant deux parois parallèles 45 faisant saillie de la face interne du vantail 7 perpendiculairement à celle-ci et qui peuvent s'engager entre les deux parois latérales 34 de la chape d'articulation correspondante 33 de la pièce en cornière 30.Each hinge element 44 is in the form of a yoke comprising two parallel walls 45 projecting from the inner face of the leaf 7 perpendicular thereto and which can engage between the two lateral walls 34 of the corresponding hinge yoke 33 of the corner piece 30.

Les deux parois latérales 45 sont raccordées l'une à l'autre par une paroi formant âme 46 également perpendiculaire à la face interne du vantail 7 en étant distante du bord correspondant 7a du vantail 7, les bords opposés des deux parois latérales 45 de l'élément d'articulation 44 étant situés sensiblement dans le même plan que ce bord et perpendiculaire au vantail 7.The two side walls 45 are connected to one another by a core wall 46 also perpendicular to the inner face of the leaf 7 while being spaced from the corresponding edge 7a of the leaf 7, the opposite edges of the two side walls 45 of the articulation element 44 being located substantially in the same plane as this edge and perpendicular to the leaf 7.

Les deux parois latérales 45 d'un élément d'articulation 44 comprennent respectivement deux orifices 47 de dimensions supérieures au diamètre de l'axe d'articulation 37 pour permettre au vantail 7 de pivoter librement, sans coincement entre sa position abaissée de fermeture de l'ouverture O du cadre 1 et sa position relevée de dégagement de cette ouverture à laquelle le vantail s'étend sensiblement perpendiculairement au plan passant par les bords supérieurs des parois latérales 5 du cadre 3.The two side walls 45 of a hinge member 44 respectively comprise two orifices 47 of dimensions greater than the diameter of the hinge pin 37 to allow the leaf 7 to pivot freely, without jamming between its lowered position of closure of the hinge. opening O of the frame 1 and its raised position of clearance of this opening to which the leaf extends substantially perpendicular to the plane passing through the upper edges of the side walls 5 of the frame 3.

Les deux éléments d'articulation en forme de chape 44 d'un vantail 7 peuvent être montés de manière articulée aux éléments d'articulation en forme de chape 33 de la pièce en cornière 30 situés d'un même côté relativement au plan médian transversal de la pièce en cornière 30.The two clevis-shaped hinge members 44 of a leaf 7 may be hingedly mounted to the clevis hinge members 33 of the angle piece 30 located on the same side relative to the transverse median plane of the corner piece 30.

Le regard de chaussée peut également être pourvu d'un vérin 50 d'assistance à l'ouverture de chaque vantail 7 monté articulé au cadre 3. Chaque vérin d'assistance 50 comprend un corps 51 dont l'extrémité comporte une chape 52 montée articulée à une chape 53 solidaire de la face interne du vantail 7 par l'intermédiaire d'un axe d'articulation 54 s'étendant suivant une direction parallèle à la face interne du vantail 7 et à la paroi latérale 5 du cadre 3 à laquelle le vantail est articulé.The manhole can also be provided with a cylinder 50 for assisting the opening of each leaf 7 mounted hinged to the frame 3. Each assistance cylinder 50 comprises a body 51 whose end comprises a yoke 52 mounted articulated to a yoke 53 secured to the inner face of the leaf 7 by means of a hinge axis 54 extending in a direction parallel to the inner face of the leaf 7 and the side wall 5 of the frame 3 to which the leaf is articulated.

Le vérin d'assistance 50 a sa tige 55 dont l'extrémité comporte une chape 56 pouvant être logée entre deux parois latérales 39 d'une chape 38 de la pièce en cornière 30 en étant montée articulée entre ses parois latérales 39 par l'intermédiaire de l'axe d'articulation 41 traversant les deux chapes 38 et 56.The assistance cylinder 50 has its rod 55 whose end comprises a yoke 56 that can be housed between two side walls 39 of a yoke 38 of the angle piece 30 being articulated between its side walls 39 via of the hinge pin 41 passing through the two yokes 38 and 56.

Le regard de chaussée peut également être pourvu d'une jambe 60 interposée entre chaque vantail 7 et le cadre 3 pour maintenir le vantail 7 à sa position relevée de dégagement de l'ouverture O du cadre 3 et l'empêcher de basculer vers sa position de fermeture de cette ouverture, par exemple en cas de vent fort et/ou d'éviter la fermeture involontaire du vantail 7 par une tierce personne pendant qu'une autre intervient dans la chambre 2.The manhole can also be provided with a leg 60 interposed between each leaf 7 and the frame 3 to hold the leaf 7 in its raised position of the opening O of the frame 3 and prevent it from tilting towards its position closing this opening, for example in the event of strong wind and / or to avoid the involuntary closing of the leaf 7 by a third person while another intervenes in the chamber 2.

La jambe 60 a l'une de ses extrémités montée articulée à la pièce en cornière 30 solidarisée à la paroi latérale correspondante 5 du cadre 3 par l'intermédiaire d'une chape 61 dont les deux parois latérales 62 sont solidaires de l'aile 32 perpendiculairement à celle-ci de la pièce en cornière 30.The leg 60 has one of its ends hinged to the bracket member 30 secured to the corresponding side wall 5 of the frame 3 by means of a yoke 61 whose two side walls 62 are integral with the flange 32 perpendicular thereto of the angle piece 30.

Un axe d'articulation 63 traverse la chape 61 et une ouverture 64 de la partie d'extrémité inférieure de la jambe 60, laquelle ouverture 64 est conformée pour participer au blocage du vantail 7 à sa position relevée représentée sur les figures 3 et 4 et désengager la jambe 60 de cette position de blocage par traction vers le haut sur celle-ci à partir de la position relevée du vantail 7.A hinge pin 63 passes through the yoke 61 and an opening 64 of the lower end portion of the leg 60, which opening 64 is shaped to participate in the locking of the leaf 7 in its raised position shown in FIGS. figures 3 and 4 and disengaging the leg 60 from this locking position by pulling it upwards from the raised position of the leaf 7.

La partie d'extrémité de la jambe 60 opposée à celle articulée à la pièce en cornière 30 traverse une fenêtre 65 d'une patte 66 solidaire de la face interne du vantail 7 perpendiculairement à celle-ci.The end portion of the leg 60 opposite that hinged to the angle piece 30 passes through a window 65 of a lug 66 integral with the inner face of the leaf 7 perpendicular to it.

L'extrémité libre de la jambe 60 traversant la fenêtre 65 comporte une partie recourbée à angle droit 67 disposée au-dessus et à proximité de la patte 66 lorsque le vantail 7 occupe sa position relevée pour également empêcher le basculement du vantail 7 vers sa position de fermeture de l'ouverture O du cadre 3.The free end of the leg 60 passing through the window 65 has a right-angle curved portion 67 disposed above and close to the tab 66 when the leaf 7 is in its raised position to also prevent the leaf 7 from tilting towards its position. closing the opening O of the frame 3.

Pour débloquer chaque vantail 7 de sa position relevée, l'opérateur exerce une traction vers le haut sur la jambe 60 pour désengager la partie recourbée à angle droit 67 au-dessus de la patte 66 au travers de la fenêtre 65 avec l'ouverture 64 conformée pour permettre le désengagement de la jambe 60 à une position permettant au vantail 7 de basculer à sa position d'obturation de l'ouverture O du cadre 3.To unlock each leaf 7 from its raised position, the operator pulls up on the leg 60 to disengage the bent portion at right angles 67 above the tab 66 through the window 65 with the opening 64 shaped to allow the disengagement of the leg 60 to a position allowing the leaf 7 to switch to its closed position of the opening O of the frame 3.

Chaque vérin d'assistance 50 et chaque jambe 60 sont déjà connus en soi et n'ont pas besoin d'être détaillés.Each assistance cylinder 50 and each leg 60 are already known per se and do not need to be detailed.

Il est à noter que la chape 61 d'articulation de la jambe 60 n'est pas représentée en figure 6 pour la simplicité.It should be noted that the clevis 61 of articulation of the leg 60 is not represented in FIG. figure 6 for simplicity.

En outre, d'autres moyens de sécurisation peuvent être utilisés, tels que par exemple un bras autobloquant à glissière, connu en soi, dont une extrémité peut être fixée de manière articulée à la pièce en cornière 30.In addition, other securing means may be used, such as for example a slide self-locking arm, known per se, one end of which may be hingedly attached to the angle piece 30.

Chaque vantail 7 comporte deux paires d'entailles parallèles 70 partant du bord 7a du vantail 7 sur une longueur légèrement supérieure à la largeur des parois latérales 34 des chapes d'articulation 33, les entailles 70 traversant l'épaisseur du voile 7b du vantail 7.Each leaf 7 comprises two pairs of parallel notches 70 starting from the edge 7a of the leaf 7 over a length slightly greater than the width of the side walls 34 of the articulation yokes 33, the notches 70 passing through the thickness of the web 7b of the leaf 7 .

Chaque paire d'entailles 70 permet à deux parois latérales 34 d'une chape d'articulation 33 de traverser ces deux entailles lorsque le vantail correspondant 7 occupe sa position d'obturation de l'ouverture O du cadre 3 comme cela ressort mieux de la figure 1 qui montre que la paroi formant âme 35 de chaque chape d'articulation 33 se trouve en regard et à proximité de la paroi correspondante 5 du cadre 3.Each pair of notches 70 allows two side walls 34 of a hinge yoke 33 to pass through these two notches when the corresponding leaf 7 occupies its closed position of the opening O of the frame 3, as is more readily apparent from the figure 1 which shows that the core wall 35 of each articulation clevis 33 is opposite and close to the corresponding wall 5 of the frame 3.

Les axes d'articulation cylindriques 37, 41, 54 et 63 sont maintenus dans leurs chapes respectives 33, 38, 53, 61 en ayant l'une de leurs extrémités comportant une tête de butée et leurs extrémités opposées comportant des goupilles, mais ils peuvent être constitués par des boulons comme celui reliant l'extrémité de la jambe 60 à la chape 61 de la pièce en cornière 30 (voir figure 5).The cylindrical hinge pins 37, 41, 54 and 63 are held in their respective yokes 33, 38, 53, 61 having one of their ends having a stopper head and their opposite ends having pins, but they can be constituted by bolts such as that connecting the end of the leg 60 to the clevis 61 of the corner piece 30 (see figure 5 ).

Lorsqu'il est nécessaire de remplacer un ensemble à cadre et couvercle de regard de chaussée existant, selon lequel le cadre scellé dans le sol est fermé par le couvercle à deux vantaux reposant dans le cadre sans être articulé à celui-ci, par un ensemble selon lequel les vantaux doivent être montés articulés sur un côté du cadre, il suffit tout simplement de percer les trous taraudés 43 dans les faces d'assise 10 s'étendant le long de la paroi latérale correspondante 5 du cadre existant enfoui dans le sol puis de poser la pièce en cornière 30 entre les deux parois latérales 5 perpendiculaires à la paroi 5 adjacente à la face d'assise en amenant l'aile 31 de la pièce 30 en appui sur les faces d'assise 10. Ensuite, l'opérateur fixe l'aile 31 sur les faces d'assise 10 par les vis de fixation 42 introduites dans les trous taraudés 43 au travers des perçages 31a en forme de trous oblongs pour régler la position de la pièce en cornière 30 relativement à la paroi 5. Après serrage des vis 42, l'opérateur saisit un vantail 7 de manière à disposer ses deux éléments d'articulation en forme de chapes 44 respectivement dans les deux éléments d'articulation en forme de chapes 33 de la pièce en cornière 30 et il introduit ensuite les axes d'articulation 37 au travers de ces chapes pour rendre le vantail 7 articulé au cadre. L'opérateur procède de même pour le second vantail 7 afin de le rendre articulé au cadre.When it is necessary to replace a frame assembly and existing manhole cover, in which the frame sealed in the ground is closed by the two-leaf cover resting in the frame without being hinged to it, by a set according to which the leaves must be mounted articulated on one side of the frame, it suffices simply to drill the threaded holes 43 in the seat faces 10 extending along the corresponding side wall 5 of the existing frame buried in the ground then to place the piece in angle 30 between the two side walls 5 perpendicular to the wall 5 adjacent to the seat face by bringing the wing 31 of the piece 30 bearing on the seat faces 10. Then the operator fixed the wing 31 on the seat faces 10 by the fastening screws 42 introduced into the tapped holes 43 through the holes 31a in the form of oblong holes to adjust the position of the piece angle 30 relative to the paro 5. After tightening the screws 42, the operator grasps a leaf 7 so as to arrange its two clevis-shaped hinge members 44 respectively in the two clevis-shaped hinge members 33 of the angle piece 30. and it then introduces the hinge pins 37 through these yokes to make the leaf 7 hinged to the frame. The operator does the same for the second leaf 7 to make it hinged to the frame.

Au besoin, l'opérateur peut également monter le vérin d'assistance à l'ouverture 50 en assemblant ses chapes respectives 52, 56 entre la chape 53 de chaque vantail correspondant 7 et la chape 38 de la pièce en cornière 30 à l'aide des axes d'articulation 54 et 41. En outre, s'il est nécessaire d'équiper également chaque vantail 7 d'une jambe 60 de maintien à la position relevée de ce vantail, il suffit tout simplement d'engager la jambe 60 au travers de la fenêtre 65 de la patte 66 du vantail 7 et de monter de manière articulée son extrémité opposée à l'extrémité coudée 67 dans la chape 61 de la pièce en cornière 30 à l'aide de l'axe d'articulation 63.If necessary, the operator can also mount the assistance cylinder to the opening 50 by assembling its respective clevises 52, 56 between the yoke 53 of each corresponding leaf 7 and the yoke 38 of the angle piece 30 using hinge pins 54 and 41. In addition, if it is necessary to also equip each leaf 7 of a leg 60 to maintain the raised position of this leaf, simply simply engage the leg 60 to through the window 65 of the tab 66 of the leaf 7 and hingedly mounting its opposite end to the bent end 67 in the yoke 61 of the angle piece 30 by means of the hinge axis 63.

En position de fermeture des vantaux 7, ceux-ci sont en appui d'une part sur l'aile 31 de la pièce en cornière 30 et d'autre part sur la face d'assise opposée 8 en conservant normalement la position d'affleurement des vantaux avec les bords supérieurs des parois 5 du cadre 3. Cependant, au besoin, il est possible de fixer une autre pièce en cornière sur la face d'assise opposée 8 pour compenser l'épaisseur de la pièce en cornière 30 à chapes et conserver cette position d'affleurement des vantaux.In the closed position of the leaves 7, they are supported on the one hand on the wing 31 of the corner piece 30 and on the other hand on the opposite seat face 8 while normally maintaining the outcrop position leaves but with the upper edges of the walls 5 of the frame 3. However, if necessary, it is possible to fix another piece in angle on the opposite seat face 8 for compensate for the thickness of the screed-end piece 30 and keep this position flush with the leaves.

L'invention ci-dessus décrite réduit considérablement les coûts d'installation d'un regard de chaussée à cadre et couvercle articulé au cadre en remplacement d'un regard de chaussée à cadre et couvercle non articulé à ce cadre puisque le cadre déjà existant scellé dans le sol est réutilisé sans avoir à le desceller et qu'il suffit par exemple de percer quelques trous taraudés pour fixer la pièce rapportée 30 pourvue des éléments d'articulation permettant le montage articulé du couvercle dont chaque vantail remplaçant le vantail existant est déjà équipé des éléments d'articulation pour des regards de chaussée existants du type à couvercle articulé au cadre. En outre, le temps d'installation d'un regard de chaussée à cadre et couvercle articulé à celui-ci est extrêmement réduit par rapport à la situation selon laquelle on serait amené à desceller un cadre existant du sol pour le remplacer par un cadre spécifique pourvu d'éléments d'articulation à un couvercle.The invention described above considerably reduces the costs of installation of a frame view frame and hinged cover to the frame in replacement of a floor frame and cover not articulated to this frame since the already existing frame sealed in the ground is reused without having to unseal it and it is sufficient for example to drill a few tapped holes to fix the insert 30 provided with hinge elements for hinged mounting of the cover, each leaf replacing the existing leaf is already equipped articulation elements for existing manholes of the hinged lid type to the frame. In addition, the installation time of a frame and cover eye hinged to it is extremely reduced compared to the situation in which it would be necessary to unseal an existing frame of the ground to replace it with a specific frame provided with hinge elements to a lid.

L'invention ci-dessus décrite constitue ainsi un kit d'articulation à fixer dans un cadre standard pour le montage de manière articulée d'un couvercle au cadre.The invention described above thus constitutes a hinge kit to be fixed in a standard frame for the articulated mounting of a cover to the frame.
