Abstract
A device, for automatic extraction of a supply drawer from a household appliance, includes a releasable locking device for releasably locking the drawer; an elastic element for pushing the drawer into an extracted position; a braking element for opposing movement of the drawer; a support housing the elastic and the braking elements; and a toothed pinion fitted idly to the support, which is configured to leave at least one given circumferential portion of the teeth of the pinion exposed. The elastic element is to exert a torque in a given direction on the pinion, which is connected angularly integral with the braking element. The exposed circumferential portion of the pinion teeth meshes selectively with a straight or curved rack, formed externally on a wall of the drawer, by simply rotating the support with respect to the drawer, so that the same device can be used for both slide-out and swing-out drawers.
