Selective locking assembly of extractable components such as furniture drawers

A selective locking assembly of extractable components, including several drawers, arranged side by side on a first row and adapted to be displaced along a horizontal direction between a retracted position and an extracted position with respect to a containing structure, the selective locking assembly being adapted for preventing the simultaneous extraction of more than one of the several drawers, and comprising at least a pair of actuating means each formed by at least one rigid elongated element extending horizontally and arranged so as to be axially rotatable in proximity to a back wall of at least one of the several drawers, each actuating means being operatively associable with a corresponding one of the several drawers through first coupling means and being also equipped, in correspondence with another of the at least one of the several drawers, with stop means configured and arranged for selectively cooperating with the another of the at least one of the several drawers to prevent/allow their extraction, each actuating means being adapted to be rotatably displaced, in response to the extraction movement of the drawer to which it is associated, from a first position, wherein the stop means allow the extraction of any one of the another of the at least one of the several drawers, to a second position, wherein the stop means interact with the another of the at least one of the several drawers thereby preventing their extraction,

• wherein the first coupling means comprise a reference member formed of a pin projecting from a rear surface of the back wall of the relative drawer and an abutment body rigidly mounted on the respective actuating means and arranged so as to interact with the reference pin in order to rotatably displace the actuating means between the first and the second position, and
• wherein the stop means comprise L-shaped elements adapted to selectively cooperate with engaging means provided on the another of the at least one of the several drawers.
