Abstract
A supporting device for furniture shelves configured to provide a reversible connection of a shelf with an opposite shoulder of a piece of furniture includes a main body, with which a movable engagement system is slidingly associated, coupled to a pin. The movable engagement system slides with respect to the main body along a sliding direction between a first non-operating position, in which the pin does not protrude from the shelf, and a second operating position, in which the pin projects outwardly from a transverse edge of the shelf. The supporting device further includes an actuation system of the engagement system and a movement-transmission system configured to transform the movement of the actuation system into a translational movement along the sliding direction of the movable engagement system.
