This invention relates to a device for an advertising sign wherein a relatively thin, flexible and translucent canopy (7) on which the desired message has been applied forms the visible front (2) of a rigid, box-shaped apparatus (1), in which, if desired, sources of light (11) are mounted. The invention is characterized in that the canopy (7) is stretched by fastening one or more of the sides of the canopy (7) to one or more tightening members (16) which, in abutment with stop means, are caused to swing in the direction away from the front (2) and toward the sides (3, 4) of the apparatus (1) so that the angle between the tightening member(s) (16) and the sides (3, 4) of the apparatus (1) becomes smaller than at the starting point, and that the tightening member(s) (16) then is/are secured to the sides (3, 4) of the apparatus (1) or prevented by other means from swinging back again. The invention is further characterized in that the stop means may consist of bent panels (9), tracks (27) in U-shaped profiles (25), channels (36) on the top side of flat profiles (25) or rows of holes on the surface of the same profiles (25) _ all close to the front (2). |
