Abstract

L'invention concerne une porte comprenant un vantail de porte et un ensemble de rails de guidage. L'ensemble de rails de guidage présente des rails complémentaires qui coopèrent avec des moyens de guidage avant montés dans la zone du bord avant, lors d'un mouvement d'ouverture, d'un organe de vantail de porte avant lors du mouvement d'ouverture, et qui présentent une troisième partie s'étendant de manière rectiligne au-dessus de la deuxième partie, s'étendant de manière rectiligne, sensiblement parallèlement à celle-ci.
