The storage cabinet comprises a frame supporting at least two superimposed rows of pivoting storage modules. The closing-opening angle of rotation beta of the storage modules is calculated according to the center distance y of the axes of rotation of the modules and of the distance x between the plane defined by the rear upper edges of the storage modules and the plane defined by the front lower edges of the storage modules according to the equation sin beta =x/y. The difference between the levels of the lower edge of the front wall of an upper adjacent module and of the upper edge of the rear wall of a lower module is calculated according to the equation z=y (1-cos beta ). The upper edge of the rear wall of a lower storage module comes in the simultaneous opening movement to stop on the lower edge of the front wall of the adjacent upper storage module so as to precisely stop rotation of the storage modules.
