Door operator system

Abstract

The present invention relates to a door operating system (1) for opening and closing an opening (2), comprising: a door frame (3) including a first frame section (4) located on a first side (5) of the opening (2) and a second frame section (6) located on a second side (7) of the opening (2); a door (8) arranged to move between a closed position (C) and an open position (O), the door (8) being movably connected to the door frame (3); a drive unit (10) mounted on the door (8), the drive unit (10) including at least one motor (11) arranged to move the door (8) from the closed position (C) to the open position (O) and from the open position (O) to the closed position (C), and vice versa; and an elongated transmission member (19) extending along at least one of the first side (5) and the second side (7) of the opening (2), wherein the drive unit (10) further includes A driven transmission member (18) is driven and connected to a motor (11), the driven transmission member (18) is movably connected to an elongated transmission member (19), and is arranged to interact with the elongated transmission member (19) by at least partially surrounding the driven transmission member (19) to drive the driven transmission member (18) along the elongated transmission member (19), wherein at least one guide member (92) mounted to the door (8) is arranged to interact with the elongated transmission member (19) to guide the elongated transmission member (19) into contact with the driven transmission member (18), wherein the at least one guide member (92) includes a sliding surface (101), the elongated transmission member (19) is configured to slide on the sliding surface (101), and wherein the sliding surface (101) has a curvature configured to cause the elongated transmission member (19) to flex and follow the curvature.
