Abstract

L'invention porte sur un raccord pour radiateurs de chauffage central, lequel raccord comprend des première et seconde parties de corps (10, 11) destinées respectivement à se raccorder à un orifice du radiateur et à l'un des tuyaux de chauffage central P menant au radiateur. Lors de l'utilisation, deux raccords sont respectivement adaptés sur les orifices d'entrée et de sortie du radiateur. Les première et seconde parties de corps (10, 11) des raccords sont interconnectées rotatives par une union, ce qui permet également un mouvement vertical relatif des parties de corps transversalement à l'axe de relation. Les raccords permettent initialement au radiateur d'être soulevé verticalement de ses étriers, de telle sorte qu'il peut être ensuite amené à pivoter vers le bas autour de l'axe de rotation à l'opposé de la paroi, afin de faciliter le nettoyage et la décoration derrière le radiateur. Un bras de support (60) facilite le soulèvement du radiateur et sert de support à ce dernier lorsqu'il se situe hors de ses étriers.
