Domestic refrigerator provided with shelves

A domestic refrigerator comprising:

• a plurality of walls defining a cavity;
• opposing supporting elements provided within the cavity, each supporting element being elongated and having a guide at one end and a seat at an opposite end;
• and
• a shelf comprising two planar portions articulated with one another, a first portion having sliders received within the guides to slidably move between first and second stable positions at different heights, a second portion rotatably mounted to the seats to rotate between a first configuration substantially coplanar with the first portion and a second configuration angled relative to the first portion;
• wherein the first portion is in the first stable position when the second portion is in the first configuration, the first portion is in the second stable position when the second portion is in the second configuration, and sliding movement of the first portion between the first and second stable positions affects rotation of the second portion between the first and second configurations;
• and
• wherein each of said guides is substantially V shaped and comprises an insertion leg for receipt of the sliders and an operational leg that ends at the top in a turned-down seat capable of retaining the respective slider stably in the first stable position.
