Tension arrangement for a door operator syste

A tension arrangement (100) for a door operator system (S), the door operator system(S) being configured for opening and closing an opening (O), the door operator system comprising:

• a door frame (10) comprising a first frame section (12) at a first side (I) of the opening (O) and a second frame section (14) at a second side (II) of the opening (O) opposite the first side (I);
• a door (20) arranged to be moved between an open position and a closed position, the door (20) being movably arranged in connection to the door frame (10);
• a drive arrangement (D), said drive arrangement comprising a drive unit (30) mounted on the door (20), said drive unit (30) comprising at least one motor (32) being arranged to move the door (20) between the open position and closed position and a first driven transmission member (34) in driving connection with the motor (32), the door operator system comprising
• a first elongated transmission member (40) extending along the first side (I) of the opening (O) between an upper position and a lower position, the first elongated transmission member (40) being configured to be connected at said upper position and at said lower position, wherein the first driven transmission member (34) is movably connected to said first elongated transmission member (40) and arranged to interplay with said first elongated transmission member (40) for driving the first driven transmission member (34) along said first elongated transmission member (40) by means of the first elongated transmission member (40) so as to move the door (20) between the closed and open position,
• wherein said tension arrangement (100) is configured to be attached in connection to said first side (I) at one of said upper and lower positions, said tension arrangement (100) comprising
• 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), said spring arrangement (130) being configured to be connected to said connection member (120) so as to facilitate adapting the spring load of said spring member (132),
• wherein said tension device (T) is configured to be arranged in connection to said bracket member (110) so that, when said first elongated transmission member (40) is connected at one of said upper and lower positions and connected to said connection member (120) at the other of said upper and lower positions, tension of said first elongated transmission member (40) is provided.
