<p>The invention relates to a shutter for a roller shutter assembly, the shutter comprising a series of shutter panels (10) and a plurality of connecting arms (20). The shutter panels (10) each have an upper edge (11) and a lower edge (12), a first face (13) and a second face (14), and the first faces (18) all face to a first side of the shutter and the second faces (14) all face to an opposite second side of the shutter. The connecting arms (20) each have a lower edge (21) and an upper edge (22), a lower one of two adjacent shutter panels in the series is pivotally connected to a higher one of the two adjacent shutter panels by at least two of the connecting arms (20). The lower edge (21) of each of the at least two connecting arms (20) is pivotally connected to an upper pivotal connection on the first face (13) of the lower of the two adjacent shutter panels, the upper pivotal connection being spaced below the upper edge of the lower shutter panel (10). The upper edge (22) of each of the at least two connecting arms (20) is pivotally connected to a lower pivotal connection on the second face (14) of an upper of the two adjacent shutter panels (10), the lower pivotal connection being spaced above the lower edge (12) of the upper shutter (11) panel (10). The at least two connecting arms (20) are spaced apart along the axes of the pivotal connections between the at least two connecting arms (20) and the upper and lower shutter panels (10).</p> |
