Abstract

L’invention porte sur un dispositf d’accès (1) à une installation souterraine, comportant un cadre (2) formant une ouverture et une surface d’assise (5) pour le couvercle (3), le couvercle (3) étant monté pivotant vis-à-vis dudit cadre (2), le couvercle ayant une face supérieure et une face inférieure opposée à ladite face supérieure, le couvercle (3) pouvant prendre une position fermée dans laquelle il est en appui sur la surface d’assise (5), le dispositif d’accès comportant une jambe de maintien (7) qui comporte une portion terminale (10) en crochet. La jambe de maintien (7) est positionnée en totalité sous la face inférieure (8) du couvercle (3) et est fixée audit couvercle (3). Elle est pivotable selon un axe sensiblement orthogonal à la face inférieure (8) du couvercle (3), de sorte qu’elle peut être positionnée :- soit dans une position angulaire de maintien dans laquelle le couvercle (3) peut être amené de la position fermée à une position entrouverte dans laquelle la portion terminale (10) de la jambe de maintien (7) interfère mécaniquement avec le cadre (2) et empêche toute ouverture au-delà de ladite position entrouverte ;- soit dans une position angulaire de libération, dans laquelle le couvercle (3) peut être amené de la position fermée à une position ouverte dans laquelle l’ouverture du cadre est dégagée, sans que la jambe de maintien (7) n’interfère mécaniquement avec le cadre (2). L’invention porte également sur un procédé d’obtention d’un tel dispositif, sur la base d’un dispositif préexistant. Figure pour l’abrégé : Fig. 1The invention relates to an access device (1) to an underground installation, comprising a frame (2) forming an opening and a seating surface (5) for the cover (3), the cover (3) being mounted pivoting with respect to said frame (2), the cover having an upper face and a lower face opposite said upper face, the cover (3) being able to take a closed position in which it rests on the seat surface (5), the access device comprising a retaining leg (7) which comprises a hook-shaped end portion (10). The retaining leg (7) is positioned entirely under the lower face (8) of the cover (3) and is fixed to said cover (3). It is pivotable along an axis substantially orthogonal to the lower face (8) of the cover (3), so that it can be positioned: - either in an angular holding position in which the cover (3) can be brought from the closed position to a half-open position in which the end portion (10) of the retaining leg (7) mechanically interferes with the frame (2) and prevents any opening beyond said half-open position; - either in an angular release position , in which the cover (3) can be moved from the closed position to an open position in which the opening of the frame is clear, without the retaining leg (7) mechanically interfering with the frame (2). The invention also relates to a method for obtaining such a device, on the basis of a pre-existing device. Figure for abstract: Fig. 1
