(57) A right or left hinge for lids for electric household appliances, having a structure
of the type that comprises a supporting head (10) provided with a partially threaded
pivot (11) inserted in a helical spring (20) which acts by torsion and whose ends
(21,22) are rigidly coupled respectively to the head (10) and to an adjustment nut
(25) screwed onto the pivot thread (12), a lock nut (26), being further screwed onto
the pivot thread (12), to lock the adjustment nut (25). The helical spring (20) is
rigidly coupled, with its end (21) that lies opposite with respect to the adjustment
nut (25), to a cam element (14) through which the pivot (11) passes, and a rod (16)
cooperating with the cam element (14) is provided to convert rotary motion into axial
translational motion, the rod (16) being perpendicular to the pivot axis and being
pushed by a compression spring (27) arranged between the rod (16) and a portion of
the head (10).
