(54) Manhole cover


(57) A manhole cover, of the type constituted by a quadrangular frame (11, 111, 211), to which at least two complementary triangular lids (14, 15, 114, 115, 124, 125, 214, 215, 224, 225) are coupled by means of hinges (12, 26). A first lid (14, 114, 214) of the two complementary triangular lids is coupled to a side (13) of the frame (11) by means of a hinge (12) arranged at one of its vertices (17); the second lid (15, 115, 215) is coupled to the same side (13) by means of at least one articulation (16) arranged on its side (18) that is contiguous to the vertex (17) of the first lid (14, 114, 214). A manhole cover thus structured allows an operator to access from three sides the spaces and items arranged beneath the manhole cover.
