Description

COUVERCLE DE S RET POUR BOUCHES D' GOUTSS RET COVER FOR TASTE MOUTHS

La présente invention se rapporte à un couvercle de sreté pour bouches d'égouts, dont l'objectif réside dans 5 sa conformation comme couvercle de sreté présentant dans sa structure des caractéristiques qui le dotent d'une double sécurité, évitant l'apparition de situations malencontreuses, en particulier lors d'inondations, aux cours desquelles les couvercles d'égouts ordinaires sont 10 déplacés hors de leur emplacement habituel à cause de la pression de l'eau qui émerge verticalement, ceci produisant une ouverture qui peut conduire à ce que les personnes et les véhicules qui passent par cet endroit puissent s'introduire par les bouches étant donné que les cavités de 15 celles-ci sont complètement invisibles du fait que les rues ou les zones o elles se situent sont recouvertes par une  The present invention relates to a safety cover for manholes, the objective of which lies in its conformation as a safety cover having in its structure characteristics which endow it with double security, avoiding the appearance of situations. unfortunate, especially during floods, in which ordinary sewer covers are moved out of their usual location due to the pressure of water emerging vertically, this producing an opening which can lead to the people and vehicles passing through this place can enter through the mouths since the cavities of these are completely invisible because the streets or the areas where they are located are covered by a

hauteur d'eau considérable.considerable height of water.

Cette invention s'applique au secteur des industries 20 dédiées à la fabrication de couvercles pour les égouts,  This invention applies to the sector of industries 20 dedicated to the manufacture of covers for sewers,

plus concrètement pour les bouches d'égouts.  more concretely for the manholes.

L'art antérieur connaît déjà un grand nombre de couvercles applicables aux bouches d'égouts, aux coffrets, 25 aux constructions enfouies sous le sol pour effectuer l'installation de nombreux éléments, comme les connexions électriques, de gaz, d'eau, etc., qui présentent dans la partie correspondant à la bouche un encadrement, ou base, fabriqué de préférence avec un matériau métallique, qui 30 peut adopter n'importe quelle forme Jugée opportune, en  The prior art already knows a large number of covers applicable to manholes, boxes, constructions buried underground to perform the installation of many elements, such as electrical connections, gas, water, etc. ., which have in the part corresponding to the mouth a frame, or base, preferably made with a metallic material, which can take any form deemed appropriate, in

général circulaire, rectangulaire ou quadrangulaire.  general circular, rectangular or quadrangular.

Une fois l'encadrement fixé sur la structure de support, le couvercle proprement dit est incorporé sur l'ouverture pourvue d'un rebord périmétrique interne, ou saillie, et ferme la cavité d'accès. Il a été constaté que lors de l'apparition de crues, d'alluvions ou de pluie en grandes quantités, les égouts ordinaires n'offrent aucune possibilité pour évacuer 10 traditionnellement l'eau entraînée dans leurs conduites, les fluides cherchant une sortie vers l'extérieur qui provoque dans beaucoup d'occasions le déplacement du couvercle situé sur la bouche, laissant à découvert l'ouverture d'accès à l'intérieur des égouts, ladite 15 ouverture ou bouche restant recouverte d'eau, ce qui rend impossible pour les personnes et les véhicules qui se déplacent dans ce secteur la visualisation directe du trou créé par le déplacement du couvercle, situation pouvant aboutir à ce qu'une personne ou un véhicule se déplaçant 20 dans ce secteur puisse s'introduire dans la bouche  Once the frame has been fixed to the support structure, the cover itself is incorporated into the opening provided with an internal perimeter rim, or projection, and closes the access cavity. It has been observed that when floods, alluvium or rain appear in large quantities, ordinary sewers offer no possibility for traditionally discharging the water entrained in their pipes, the fluids seeking an outlet to the exterior which causes in many occasions the displacement of the cover located on the mouth, leaving uncovered the access opening to the interior of the sewers, said opening or mouth remaining covered with water, which makes it impossible for people and vehicles moving in this sector direct visualization of the hole created by the movement of the cover, situation which can lead to a person or a vehicle moving in this sector being able to enter the mouth

dépourvue de couvercle.without cover.

Afin d'éviter que ces désordres se produisent, il faudrait disposer d'une invention qui présenterait, fixée 25 au cadre ou à l'encadrement de support du couvercle sans ouverture, une grille supplémentaire incorporée à la zone interne qui pallierait cette possibilité citée comme occasionnelle ou accidentelle, ladite grille de sreté devant être dotée d'un moyen d'élévation ou de déplacement 30 dans le cas o serait nécessaire l'entrée par la bouche d'égout de personnel autorisé, comme par exemple les  In order to prevent these disorders from occurring, it would be necessary to have an invention which would present, fixed to the frame or the support frame of the cover without opening, an additional grid incorporated in the internal zone which would overcome this possibility cited as occasional or accidental, said safety grid to be provided with a means of elevation or displacement 30 in the case where entry by authorized sewerage of authorized personnel, such as for example the

services publics d'entretien des égouts.  public sewer maintenance services.

Néanmoins, il semble qu'il n'existe pas à l'heure actuelle de dispositifs qui présentent les caractéristiques décrites dans le présent document, et qui sont signalées  However, it seems that there are currently no devices which have the characteristics described in this document, and which are indicated

comme propres.as clean.

L'invention est dotée de moyens appropriés qui permettent le déplacement de la grille de sreté dans le cas o elle devrait être libérée pour que les services 15 publics puissent accéder à l'intérieur des égouts, si nécessaire. L'invention concerne un couvercle de sreté pour bouches d'égout, celles formées à partir d'un cadre ou 20 châssis fabriqué en matériau métallique de même que l'ensemble des pièces qui composent ledit couvercle, qui présente une saillie périphérique munie de perforations pour sa fixation sur la base, incorporant deux renforcements latéraux entre lesquels se déplace un crochet 25 qui, en guise de charnière permet l'élévation et l'abaissement d'un couvercle sans ouverture muni de nervures situées sur la partie interne, caractérisé par le fait que dans la zone interne du cadre ou châssis est incorporée une saillie périphérique ou échelonnement o 30 s'assemble une grille de forme identique au cadre ou châssis, disposant d'un élément d'immobilisation applicable  The invention is provided with suitable means which allow the movement of the security grid in the event that it should be released so that the public services can access the interior of the sewers, if necessary. The invention relates to a safety cover for manholes, those formed from a frame or chassis made of metallic material as well as all the parts which make up said cover, which has a peripheral projection provided with perforations. for its attachment to the base, incorporating two lateral reinforcements between which a hook 25 moves which, by way of hinge allows the raising and lowering of a cover without opening provided with ribs located on the internal part, characterized by fact that in the internal zone of the frame or chassis is incorporated a peripheral projection or staggering where a grid of identical shape is assembled to the frame or chassis, having an applicable immobilizing element

sur la grille et préparé pour être libéré.  on the grid and prepared to be released.
