(FR) DISPOSITIF D'AFFICHAGE LUMINEUX
Abstract
(EN) An illuminated display device (10) according to the present invention comprises an image sheet (48) comprising, in turn, a plurality of series of image portions (47a, 47b, 47c) etc. and a mask sheet (62) having alternative opaque strips (63) and transparent windows (61). The mask sheet (62) is located in face-to-face relation to the image sheet (48). First and second roller means (64, 66) are located in a substantially parallel spaced-apart arrangement relative to the image sheet (48) and the mask sheet (62) and are operatively associated with one of the image sheet (48) and the mask sheet (62). The device (10) is provided with means to oscillatingly move the one of the image sheet (48) and the mask sheet (62) relative to the other of the image sheet (48) and the mask sheet (62). The moving means comprises a drive means (84), a cam (88); a cam follower lever (90) or (91) associated with the cam (88); and a crank mechanism comprising a crank lever (92) or (94) operatively associated with the first roller means (64) and a linkage mechanism comprising the cam follower lever (90) or (91) and the crank lever (92) or (94).
(FR) L'invention concerne un dispositif d'affichage lumineux (10) comprenant une feuille image (48) qui comporte, à son tour, une pluralité de parties image (47a, 47b, 47c) et une feuille masque (62) présentant des bandes opaques (63) et des fenêtres transparentes (61). La feuille masque (62) est placée face à la feuille image (48). Des premier et second organes d'enroulement (64, 66) sont placés sensiblement parallèles et espacés par rapport à la feuille image (48) et la feuille masque (62) et sont associés de manière opérationnelle à l'une des feuilles image (48) et masque (62). Le dispositif (10) est pourvu d'organes conçus pour déplacer de manière oscillatoire la feuille image (48) et la feuille masque (62) l'une par rapport à l'autre. Les organes de déplacement comprennent un organe d'entraînement (84), une came (88), un élément galet suiveur (90, 91) associé à la came (88) et un mécanisme à manivelle comprenant un élément manivelle (92, 94) associé de manière opérationnelle au premier organe d'enroulement (64) et à un mécanisme de couplage comprenant l'élément galet suiveur (90, 91) et l'élément manivelle (92, 94).
