Movement system of large cases (7) that consists of a satisfactory number of cases, which bear objects (furniture) for exhibition to standing spectators, and which can move horizontally and vertically with the help of rectilinear guides (13, 12, 4) and hydraulic propellants (1, 2, 10, 11, 14, 15, 16) within a frame or a construction. The cases bear two rows of wheels (8, 18) that move in reverse (P) and are placed on the top of the previous box in series (17, 19). The movement of the boxes one by one is accomplished with the help of automatic operating pins that hold in place the rest of the cases during the moving stage of the upper and lower placed cases. |
