Abstract

Cette fermeture à tourniquet pour le verrouillage d'un couvercle de regard, d'une grille ou similaire sur son cadre est du type dans lequel le tourniquet est monté sur le couvercle de sorte qu'on puisse le faire tourner au moyen d'un boulon fileté, ce tourniquet s'engageant en position de verrouillage au-dessous d'une surface d'arrêt prévue sur le cadre et pouvant être serré contre cette surface par rotation du boulon fileté. En position de verrouillage, le tourniquet 6 et la surface d'arrêt 10 sont sollicités élastiquement l'un contre l'autre par au moins un ressort 7 qui agit sur le tourniquet 6 et/ou sur la surface d'arrêt 10 et qui est mis sous pression par serrage du boulpn fileté 3. Grâce à cette construction, lorsque le tourniquet est en position de verrouillage, il ne peut pas tourner intempestivement dans sa position d'ouverture, même en cas de vibrations permanentes.
