Abstract: ASSA ABLOY Entrance Systems AB has developed the present invention relates to a connection device (100) for a door operator system(S) for opening and closing an opening (O). Said door operator system(S) comprises a door (20) and a drive unit mounted on said door (20) and arranged to move the door (20) between an open and closed position. The door operator system comprises an elongated transmission member (40) extending along a side of the opening (O), wherein a driven transmission member (34) of said drive unit (30) is arranged to interplay with said first elongated transmission member (40) so as to move the door (20) between the closed and open position. Said tension arrangement (100) comprises a bracket member (110) for facilitating attachment of said tension arrangement (100); a tension device (T) comprising a connection member (120) for connecting said first elongated transmission member (40) and a spring arrangement (130) comprising a spring member (132).

Abstract: The disclosure relates to a sliding door operator system (1) for opening and closing an opening (2), comprising: a track (3) configured to be mounted at an upper part (21) of the opening (2), one or more sliding door(s) 10 slidably connected to the track (3) and comprising a door leaf (4) configured to be moved along the track (3) between an open (o) and closed (c) position, and a drive unit (5) mounted on the door leaf (4), moveably connected to the track (3) and arranged to move the door leaf (4) between the closed position (c) and the open position (o). The disclosure further relates to a drive unit (5) for moving a sliding door leaf (4) between an open and a closed position (O, C) and a control system (11) for regulating one or more sliding door (10).

Abstract: A guiding assembly (300) for guiding a sliding door leaf (101) movable along a sliding door rail (110) is provided. The guiding assembly (300) comprises a bogie (130) having a first end (132) being provided with a first steering member (136) and a second steering member (138), and an opposite end (134) comprising at least one guiding element (122) being engaged with the sliding door rail (110), wherein the bogie (130) is connected to the sliding door leaf (101). The guiding assembly (300) further comprises a guiding rail (140) having first end section (140a) and a second end section (140b). The bogie (130) is configured to pivot relative the sliding door leaf (101) as the second steering member (138) travels along the guiding rail (140).

Abstract: A door operating assembly (100) for operating a sliding door leaf (101) driven by a drive unit (112) along a sliding door rail (110), said door operating assembly (100) comprising a door bracket (150) configured to position the door leaf (101) relative the rail (110), a drive member (170) adapted to be driven by the drive unit (112), and a lever arm (160) having one end (161) pivotally connected to the drive member (170) and a remote portion (167) pivotally connected to the door bracket (150) via a cam structure (194) such that the vertical position of the door leaf (101) relative the rail (110) varies when the lever arm (170) pivots.
