Definitions

  • the present invention relates to a roller shutter for windows, doors and similar openings comprising a plurality of slats disposed in side by side relationship along minor longitudinal faces thereof which correspond to their thickness and each having at said minor longitudinal faces, attachment extensions adapted to form articulated connections with the respective attachment extensions of the adjacent slats.
  • roller shutters can be manufactured using either plastic or wood material or a metal material if particular features of sturdiness and resistance to illicit tampering are required.
  • Each roller shutter comprises a plurality of slats disposed in side by side relationship along their minor longitudinal faces corresponding to their thickness and each having attachment extensions at said minor longitudinal faces adapted to form articulated connections with respective attachment extensions of the adjacent slats so as to enable winding of the shutter itself on a roller.
  • each slat is formed of a main body consisting of a box-shaped element obtained from a pressure-bent sheet metal according to a preestablished shape that also defines the attachment extensions turned upwardly and downwardly in the operating position of the slat.
  • the known art of the standardized type generally provides for said upwardly-facing attachment extension to have a substantially arched configuration in the form of a hook, i.e. like an open eyelet, and for the downwardly-facing attachment extension to substantially consist of a sheet metal portion bent at an acute angle, i.e. having a starting flat length substantially in alignment with the main face of said slat with which a final flat length is integral, which final length is bent relative to the starting length so as to form a sharp edge therewith.
  • Said final flat length is adapted to fit the concavity of the hook-like arched extension of the underlying slat.
  • the minor longitudinal face of the slat corresponding to the downwardly-facing attachment extension generally extends according to a shape adapted to define a substantially concave hollow space intended for housing the upper attachment extension of the downwardly disposed slat.
  • a concave hollow space is laterally confined, on the side of the main slat face designed to be turned outwardly, by a final flat portion of the minor longitudinal face itself, which is substantially opposite to the starting flat length of the lower attachment extension.
  • Said final flat portion forms a beak-shaped endpiece with an end band of the adjacent main face, which is adapted to cover the upper attachment extension of the underlying slat.
  • the technical task underlying the present invention is to conceive a roller shutter for windows, doors and similar openings capable of substantially obviating the above mentioned drawbacks.
  • a roller shutter for windows, doors and similar openings comprising a plurality of slats disposed in side by side relationship along minor longitudinal faces thereof that correspond to their thickness and each having, at said minor longitudinal faces, a first attachment extension which is integral with a first minor longitudinal face of the slat and has a final arched portion in the form of a hook, and a second attachment extension which is integral with the second minor longitudinal face of the slat, characterized in that it has an arched end adapted to be housed in said hook-like arched final portion of an adjacent slat.
  • It comprises a plurality of slats 2 disposed in side by side relationship along minor longitudinal faces thereof that correspond to their thickness and comprising, for each slat, a first minor longitudinal face 3 turned upwardly when the shutter is in an operating position, and a second minor longitudinal face 4 turned downwardly.
  • Each slat 2 is formed of a box-shaped element obtained through pressure-bending of a sheet metal which is preferably externally plasticized, and comprising a main body 5 advantageously filled with foamed material. Projecting from said main body is a first attachment extension 6 integral with the first minor longitudinal face 3 and a second attachment extension 7 integral with the second minor longitudinal face 4.
  • the first attachment extension 6 of each slat is adapted to form an articulated connection with the second attachment extension 7 of the slat overlying it in an operating position.
  • both attachment extensions 6 and 7 have an arched shape. More specifically, the first attachment extension 6 comprises a hook-like arched final portion 6a substantially defining an arc of a circumference corresponding to an angle not exceeding 180°, and the second attachment extension 7 comprises an arched end 7a substantially defining an arc of a circumference corresponding to an angle not exceeding 270° and adapted to be housed in said arched final portion 6a.
  • the arched end 7a has a convex outer surface 7b the shape of which matches the shape of the concave inner surface 6b of the final portion 6a at least partly, and is suitably oriented from a base portion 7c of the second attachment extension 7 itself so that it makes the convex surface 7b abut against said concave surface 6b of the first attachment extension 6 of the overlying slat.
  • the arched final portion 6a is disposed in the continuation of a flat starting segment 6c of the first attachment extension 6 in alignment with a first main face 8 of slat 2 designed to define the inner surface of the slat, whereas the base portion 7c of the second attachment extension 7 extends starting from a second main face 9 opposite to the first main face 8 and designed to define the outer surface of the slat.
  • the base portion 7c of the second attachment extension 7 comprises a first flat length 7d in alignment with the second main face 9 and a second flat length 7e bent at an angle relative to the first length 7b.
  • the second length 7b advantageously looks slightly inclined downwardly, away from the first main face 8, to enable outflow of rainwater to the outside.
  • an inclination angle included between 6° and 8°, preferably of 7° is provided.
  • the second minor longitudinal face 4 preferably has a concave shape with a bending radius substantially corresponding to that of the arched final portion 6a of the first attachment extension 6.
  • the first flat length 7d of the second attachment extension extends in a convenient manner so as to form a space 10 sufficient to enable articulation between the slats, which space is confined between the second minor longitudinal face 4 and said arched final portion 6a of the underlying slat.
  • the starting segment 6c too of the first attachment extension 6 has a development adapted to define a hollow space 11 of appropriate sizes for operation of the roller shutter, which space is interposed between the second length 7e of the second attachment extension 7 and the first minor longitudinal face 3 of the underlying slat 2.
  • ribs are present that extend in parallel to the longitudinal axis along the whole surface of the second main face 9.
  • Such ribs are made up of substantially circular recessed grooves of a radius substantially corresponding to the distance between the length 7e of a slat and the first minor longitudinal face 3 of the adjacent slat at the region where said slats are in engagement with each other.
  • the ribs that are substantially spaced apart the same distance from each other have a camouflaging function with the hollow space 11 to which they seem to be almost identical when seen from the outside.
  • the invention achieves important advantages.
  • roller shutter in accordance with the invention enables a very high safety to be achieved due to the fact that all slats forming the roller shutter are hooked together very strongly.
  • use of roller shutters of metal material appears to be quite appropriate because the invention makes it possible to fully exploit the greater capacities of resisting breaking or burglary that these roller shutters have as compared with those made of other different materials.
