The table has a support frame with legs (4) and it has two central plates (6,6'). Under the plates there are two fixed guides (18,18') and two intermediate guides (16,16'), under the first extensions (8,8'), slide on these. The outer extensions (10,10') have guides (14,14'), under them that slide on the intermediate extensions. Folding legs (12,12') support the outer extensions when they are open. When the extensions are slid under the central plates the legs are folded under the table by a plate (22,22'), joined to each leg, whose axle slides along the outer guides.
