The support arms (11) are hinge mounted on slider blocks (12) moving along the side gutters and secured via a slot and pin couplings. The leading edge of the panel (3) is shaped to force the arms down, against spring pressure, into a storage setting with the deflector (10) over the drainage channel (9). The deflector is hinge mounted on the arms via spring levers (27) and is held in the operating position by springs (23). These are compressed by the folding action.
