A blind comprising a plurality of lamellae and a scissor-type guide for guiding the plurality of lamellae and a mount for attaching a scissor-type guide to an opening of a building structure, said scissor type guide comprising - at least two scissor links , each scissor link comprising a first scissor member and a second scissor member connected in a rotational joint , - a first end ; and - a free, second end (20") which may be extended away from and retracted towards the first end in a first direction (D 1 ), wherein each lamella has an elongate plate shape extending in a second direction (D 2 ) perpendicular to said first direction (D 1 ), said mount comprising - a first mount member ; - a second mount member , - a first rotational mount joint ; and - a second rotational mount joint , wherein a first end of the first mount member is rotatably connectable to the opening of the building structure via the first rotational mount joint ; and a first end of the second mount member is rotatably connectable to the opening of the building structure via the second rotational mount joint , and where the first and second mount members are rotatably connected to the first end of the scissor type guide , such that a second end (101 ") of the first mount member is connected to a first end of the first scissor member of the scissor link (23ʺʺ), and a second end (102") of the second mount member is connected to a first end of the second scissor member of the scissor link (23""). said scissor type guide comprising - at least two scissor links , each scissor link comprising a first scissor member and a second scissor member connected in a rotational joint , - a first end ; and - a free, second end (20") which may be extended away from and retracted towards the first end in a first direction (D 1 ), - at least two scissor links , each scissor link comprising a first scissor member and a second scissor member connected in a rotational joint , - a first end ; and - a free, second end (20") which may be extended away from and retracted towards the first end in a first direction (D 1 ), wherein each lamella has an elongate plate shape extending in a second direction (D 2 ) perpendicular to said first direction (D 1 ), said mount comprising - a first mount member ; - a second mount member , - a first rotational mount joint ; and - a second rotational mount joint , - a first mount member ; - a second mount member , - a first rotational mount joint ; and - a second rotational mount joint , wherein a first end of the first mount member is rotatably connectable to the opening of the building structure via the first rotational mount joint ; and a first end of the second mount member is rotatably connectable to the opening of the building structure via the second rotational mount joint , and where the first and second mount members are rotatably connected to the first end of the scissor type guide , such that a second end (101 ") of the first mount member is connected to a first end of the first scissor member of the scissor link (23ʺʺ), and a second end (102") of the second mount member is connected to a first end of the second scissor member of the scissor link (23""). <EOS>
