The present invention relates to a concealed hinge for enabling rotation of one part of a structure relative to another part according to a predetermined limit angle. The hinge (14) includes two opposite wings (41a, 41b) connectable to the respective parts of the structure in order to enable such rotation, and a plurality of levers (42) including a fist lever set (421) and a second lever set (422). The first set is pivotally connected to the second set so that the levers in the first set are arranged in mirrored manner with respect to the levers in the second set, and each wing (41a, 41b) has a pair of slots (43a, 43b) in which first ends (53) of said fist lever set (421) can be pivotally mounted; and a pair of holes (44a, 44b) in which second ends (54) of said second lever set (422) can be pivotally mounted.
