(57) There is disclosed a venetian blind (50) having a top bar (21), a bottom bar (20)
and horizontal slats (35) disposed between the top and bottom bars (21; 20). There
is also a raising mechanism (30, 31) for adjusting the height of a bottom bar (20)
of the venetian blind (50). The raising mechanism (30, 31) comprises a first member
(11,13) attached to the top bar (21) and a second member (10, 12) attached to the
bottom bar (20). There is also a cord (1,2), which is attached at one end of the venetian
blind (50) and is fed past the first and second members (11, 13; 10 , 12). In such
an arrangement the displacement of the free end of the cord (25) is greater than the
displacement of the bottom bar (20), to adjust the height of the bottom bar (20) with
a mechanical advantage.
