A suspension device for a sheet-shaped information medium (4), such as a poster or the like, for attachment to a wall or another surface, comprising an upper and a lower bar (1, 2) to which the information medium can be fastened, whereby the upper bar (1) is connected to a cord system having pulleys (5, 7, 13, 16, 17, 18) for raising and lowering relatively to wall elements (8, 9, 10, 11, 15) attached to the wall or the like, said cord system comprising a single cord (6) which is fastened to an upper wall element (8) attached to the wall and which runs below two pulleys (5, 18) journalled in the upper bar (1) in the vicinity of the ends thereof and runs above a third pulley (7) journalled in an upper wall element (9) attached to the wall, and depends from this third pulley (7) in order to be manipulated for raising and lowering. In order to prevent flexing of the upper bar (1) at least one additional wall element (15) is situated between the first and the second wall element (8, 9) and comprises a pulley (16) above which the cord (6) runs, and the upper bar (1) comprises two additional pulleys (13, 17) for each additional wall element (15) in the region or regions below the at least one additional wall element (15). <IMAGE> |
