A DOOR OPERATOR SYSTEM

The present invention relates to a.door operation system (1) for opening and closing an opening (2) comprising: a door frame (3) comprising a first frame section (4) at a first side (5) of the opening (2) and a second frame section (6) at a second side (7) of the opening (2); a door (8) arranged to be moved between a closed (C) and an open (O) position, the door (8) being movably connected to the door frame (3); a drive unit (10) mounted on the door (8), the drive unit (10) comprising at least one motor (11) arranged to move the door (8) from the closed (C) position to the open (O) position and vice versa, and an elongated transmission member (19) extending along at least one of the first side (5) and second side (7) of the opening (2), wherein the drive unit (10) further comprises a driven transmission member (18) in driving connection with the motor (11), the driven transmission member (18) being movably connected to the elongated transmission member (19) and arranged to interplay with said elongated transmission member (19) for driving the driven transmission member (18) along said elongated transmission member (19) by the elongated transmission member (19) at least partially wrapping around the driven transmission member (18), wherein at least one guide member (92) mounted to the door (8) is arranged to interplay with the elongated transmission member (19) for guiding the elongated transmission member (19) into contact with the driven transmission member (18), wherein the least one guide member (92) comprises a sliding surface (101) on which the elongated transmission member (19) is configured to slide, and wherein the sliding surface (101) has a curvature, which is configured to urge the elongated transmission member (19) to flex and follow the curvature. La présente invention concerne un système d'actionnement de porte (1) permettant d'ouvrir et de fermer une ouverture (2). Le système d'actionnement de porte comprenant : un cadre de porte (3) comportant une première section de cadre (4) sur un premier côté (5) de l'ouverture (2) et une seconde section de cadre (6) au niveau d'un second côté (7) de l'ouverture (2) ; une porte (8) agencée pour être déplacée entre une position fermée (C) et une position d'ouverture (O), la porte (8) étant reliée de façon mobile au cadre de porte (3) ; une unité d'entraînement (10) montée sur la porte (8) et comportant au moins un moteur (11) agencé pour déplacer la porte (8) de la position fermée (C) à la position d'ouv
