<p>An advertising device is composed of several adjacent image elements (1) that are able to rotate around their longitudinal axes. Each individual image element carries on each side an image carrier (2) which receives a longitudinal strip of the whole advertising image. The cross-section of the image carrier has essentially the form of a box (21) provided with an opening (5) on the side facing the image element (1). A leaf spring (3) is fastened with rivets (4) to the image element (1). The image carrier bears with its opening (5) against the free end (31) of the leaf spring (3), so that latter can ingress into the box (21). The image carrier (2) then slides downwards until it reaches a stop and the leaf spring (3) holds it immovably on the inner side of the box (21). The assembly is dismounted in the reverse order. It thus becomes possible to easily exchange image carriers (2) and to replace them on the spot by new, already prepared image carriers.</p> |
