<p>Method enabling to modify the classification of superposed cards. The device enabling to implement such method is comprised of vertical slides consisting of a bottom (14) and two flanges (15) carrying pins (16) on which the cards (17, 26) are bearing. The cards have a head such that when a card (25) is inserted between two other cards it spaces apart the card which is under (26) from its bearings (16) thereby initiating the fall of the card which will cause the following card to fall and so on all cards which are under will fall down by one space in cascade until they find available bearings (16). Fields of utilization: bureautics (evolutive plannings); sports: continuous display of classification with successive performances.</p> |
