Abstract

La présente invention concerne un dispositif de rail de guidage d'ascenseur, dans lequel un premier élément de rail a une première surface de lame et une première surface arrière. Un second élément de rail a une seconde surface de lame et une seconde surface arrière. Une première surface inclinée qui est inclinée dans la direction verticale par rapport à la première surface de lame est formée sur la première surface arrière. Une plaque articulée présente une première surface de chevauchement et une seconde surface de chevauchement. La première surface de chevauchement est inclinée par rapport à la seconde surface de chevauchement. Lorsque la seconde surface de chevauchement est placée sur la seconde surface arrière, la première surface de chevauchement est parallèle à la première surface inclinée. Lorsqu'une pluralité d'éléments de fixation sont desserrés, la position de la plaque articulée par rapport au corps de rail de guidage peut être ajustée dans la direction verticale.
