A slat for a rolling shutter is provided that is formed as a single walled, continuous bent sheet. The slat includes a body having a hook-shaped engaging track at a first end, and a receiving track at the second end comprising a guard member and a hook-shaped lip member that form a pocket for receiving the engaging track of another slat. The guard member includes a portion of the sheet that is bent over on itself. The lip member extends from the guard member, and is spaced apart from the guard member to define an aperture that is sized and shaped to receive the engaging track of the other slat.

A rolling shutter mechanism and a method for protecting a rolling shutter assembly covering an opening. The rolling shutter assembly includes a shutter, guide rails, a shutter roller and a locking mechanism. The rolling shutter mechanism includes protecting means to cover the rolling shutter assembly. The protecting means include a protecting box covering the shutter roller, protecting frames covering the guide rails and a protecting unit covering the lower part of the shutter when it is in its closed position.

A slat for roller shutters includes an internally hollow elongated body extending along a longitudinal direction with a first face and opposite second face, designed to turn respectively towards the outside and inside of the compartment closed by the shutter. A cavity along a first longitudinal edge of the body is delimited by a first appendage on the first face, and a second appendage on the second face. A coupling appendage extends from a second longitudinal edge. Two recesses are at ends of the second longitudinal edge. Two notches on the second appendage near the opposite ends extend transverse to the first longitudinal edge, and define, on the second appendage, first and second tabs at opposite ends of the body. Each tab bends against the first appendage to close the coupling cavity at the ends of the body. The first appendage extends continuously from one end of the body.

A roller shutter may include a rotatable drum; a shutter curtain including a series of three or more elongate slats pivotally interlocked in a longitudinal-edge-to-longitudinal-edge arrangement and arranged parallel to the rotatable drum, wherein a first and second longitudinal end portions of each elongate slat may be respectively aligned to form a first side border and a second side border, respectively, of the shutter curtain, wherein the first and second longitudinal end portions of each elongate slat may be respectively provided with at least one eyelet-structure which protrudes therefrom, whereby a first and second rows of eyelet-structures are formed along the first and second side borders; and at least a first cord and a second cord respectively strung loosely through all eyelet-structures of respective row of eyelet-structures, and each cord may be configured to confine all eyelet-structures of the respective row of eyelet-structures within a length of each cord.

An elongate shell for forming a slat for a rolling door includes a planar portion having parallel first and second longitudinal edges and formed along the first longitudinal edge with a first arcuate segment and formed along an opposing second longitudinal edge with second arcuate segment, the first and second arcuate segments being positioned on the same side of said planar portion and configured and dimensioned to enable the second arcuate segment of a first shell to be received with clearance within a first arcuate segment of second shell identical to the first shell to form an articulated joint hingedly connecting the elongate shells so they can be pivoted relative to each other. Two identical shells can be oriented to be assembled to form a double-walled slat with longitudinal hooks or claws for assembling a plurality of slats, with or without insulation, into a curtain assembly for a rolling door.
