Abstract

L'invention concerne un ensemble support pour un module photovoltaïque PV (25), comprenant une fixation de maintien (1) et une poutre (3). Cette poutre (3) peut être montée sur un composant (2) du support au moyen de la fixation de maintien (1). Cette opération doit pouvoir être exécutée rapidement et de manière ergonomique par une seule personne. A cet effet, la fixation de maintien (1) comprend une portée de roulement ouverte latéralement dans laquelle un axe d'articulation (4) fixé sur la poutre (3) peut être inséré latéralement à partir d'une position (PO) séparée de la fixation de maintien (1). Dans une première position d'oscillation (P1) de la poutre (3) et dans une deuxième position d'oscillation (P2, P2') de la poutre qui est tournée par rapport à ladite première position, l'axe d'articulation (4) fixé sur la poutre (3) est inséré dans la portée de roulement latéralement ouverte. Ladite poutre (3) présente une surface de butée (8) pouvant buter contre une surface de blocage de la fixation de maintien (1). Cette surface de blocage est disposée dans une zone à l'arrière de la portée de roulement ouverte latéralement, de manière que dans la première position d'oscillation (P1), l'axe d'articulation (4) fixé sur la poutre (3) puisse sortir latéralement de la portée de roulement ouverte latéralement, et que dans la deuxième position d'oscillation (P2, P2') de la poutre (3), une sortie latérale de l'axe d'articulation (4) fixé sur la poutre (3) et se trouvant dans la portée de roulement ouverte latéralement (5) soit empêchée au niveau de la surface de blocage par l'intermédiaire d'une butée contre la surface de butée (8). Ladite poutre peut être fixée sur la fixation de maintien sur le lieu de montage, pratiquement sans outil, et sans accessoire à fournir séparément.
