A support structure for leaf shutters (2) comprises two facing uprights (4,5), an upper cross-member (6) connecting together said uprights (4,5) and hinges (8) for enabling the shutter leaves (3) to rotate. Advantageously the hinges (8) fixed to a respective upright (4,5) are positioned so as to have their respective axes of rotation substantially aligned together along a straight line (X-X) intersecting the upper cross-member (6). Furthermore the upper cross-member (6) defines a housing (9) suitable for housing actuating means (12) for actuating the shutter leaves, so that the actuating means (12) have a rotating shaft (13) extending in alignment with the axes of rotation of the hinges (8) of a respective upright (4,5). |
