Abstract: The present invention relates to a device which makes it possible to use the maximum height of the room or of the warehouse in a storage zone without using a forklift truck apparatus or, more simply, a chair or ladder. The device allows contents located outside an ergonomic zone to be made accessible by moving them in order to bring them within the reach of every user. The device adapts its dimensions (height, width, depth, volume) to all types of storage conditions, whether for a kitchen unit, an office unit or a storage rack. This invention promotes independence of disabled persons (in a wheelchair or the like), by increasing and facilitating their access to inaccessible storage, while reducing the floor space taken up.
