Definitions

  • the subject of the present invention is a slat for roller shutters and a shutter comprising said slat.
  • a roller shutter for windows and glass doors consists of a plurality of slats which are identical to each other and coupled to each other along respective longitudinal edges.
  • the slats are shaped so as to be able to be mutually coupled to each other.
  • the coupling zones are configured to allow partial rotation between the slats about the longitudinal direction.
  • the roller shutter is able to roll up on itself.
  • the roller shutter may be completely or partially raised by rolling one or more slats into a suitable container arranged above the window or glass door space, depending on the opening requirements of the space.
  • a traditional slat D consists of an elongated body E made of metal or plastics material, which body comprises a coupling appendage A extending along the whole of an upper longitudinal edge BS and a hollow seat C extending along the whole of a lower longitudinal edge BI.
  • the coupling appendage A is made as one piece with the elongated body E.
  • the hollow seat C and the coupling appendage A are shaped so as to allow mutual coupling.
  • the coupling appendage of a slat fits into the hollow seat of the above slat so as to be able to slide, in a direction Y transverse to the longitudinal direction X, between a position in which it is completely inserted in the hollow seat ( Fig. 4a ) and a position in which is it partially removed from the hollow seat ( Fig. 4b ).
  • the coupling appendage still connects the two slats together, but is free to rotate with respect to the hollow seat, allowing mutual rotation between the slats ( Fig. 4c ) and thus allowing the shutter to roll up.
  • the slats have a plurality of longitudinal slits F, which slits allow minimal air circulation and minimal light ingress even when the shutter occupies the entire span of the space but is not totally unrolled.
  • a traditional slat consists of an elongated body which may be made of a metal material or plastics material. If the elongated body is made of a metal material, it is made by bending and profiling a metal sheet. In this case, the longitudinal ventilation and lighting slits are made by means of punching. Considering the reduced dimensions of the coupling appendages and the fact that the appendages themselves are defined by two overlapping portions of sheet metal, this operation may be difficult and does not always lead to satisfactory aesthetic results.
  • the main object of this invention is to completely or partly eliminate the disadvantages of the aforementioned prior art by providing a slat for roller shutters that allows the ventilation and lighting slits in the coupling appendages to be created in a simpler manner.
  • a further object of this invention is to provide a slat for roller shutters that is simple and cost-effective to produce.
  • the slat 1 for roller shutters according to the invention has been indicated as a whole by reference sign 1 in the accompanying figures.
  • the slat 1 for roller shutters comprises:
  • the coupling cavity 20 is intended to be engaged by the coupling appendage 30 of a first slat identical to said slat 1, while the coupling appendage 30 is intended to engage the coupling cavity 20 of a second slat (not shown in the figures) identical to said slat 1.
  • the coupling cavity 20 is designed to define, with a coupling appendage 30, an articulated coupling, wherein the coupling appendage 30 is free to slide inside said cavity 20 in a direction Y transverse to said longitudinal direction X (see Fig. 7a and 7b ) and to rotate at least partially about said longitudinal direction (see Fig. 7b and 7c ).
  • the coupling cavity 20 is defined by a chamber which extends from the first longitudinal edge 11 toward the second longitudinal edge 12 of the elongated body 10 in the aforesaid transverse direction Y. At the first edge 11, the chamber is partially closed by a bottom wall 22 which delimits a longitudinal aperture 21.
  • the coupling appendage 30 extends from the elongated body 10 with a free hook-shaped end (in the following also referred to as a coupling portion 30a). In the assembled condition, the free hook-shaped end is inserted into the coupling cavity 20 and is free to slide inside the chamber by passing through the aforesaid longitudinal aperture 21.
  • the free hook-shaped end is dimensioned such that it does not fit through the longitudinal opening 21, and such that it engages the bottom wall of the chamber.
  • the latter acts as an end stop, preventing the coupling appendage 30 from completely leaving the coupling cavity, and at the same time defines the center of rotation of the articulated coupling (see Fig. 7b and 7c ).
  • the coupling appendage 30 consists of one or more profiled elements 31, 32, 33, 34 which are separate with respect to the elongated body 10.
  • Each of these one or more profiled elements 31, 32, 33, 34 is engaged on said elongated body 30 at a longitudinal engagement seat 13 which is made on the elongated body 10 along said second longitudinal edge 12.
  • Each profiled element 31, 32, 33 and 34 protrudes from the elongated body 10 with a coupling portion 30a which protrudes from said longitudinal engagement seat 13.
  • the slat 1 comprises one or more ventilation and lighting apertures that are defined by:
  • the coupling appendage 30 of the slat consists of one or more elements which are separate with respect to the elongated body 10 (i.e. not made as one piece therewith), it is possible to simplify the production of the ventilation and lighting apertures on the slat.
  • these apertures may be made by making holes on the single profiled element or on multiple profiled elements that form the coupling appendage, which elements are separate from the elongated body. This avoids production complications from making the holes in the elongated body that forms the coupling appendage.
  • these apertures may be defined without making holes in the profiled elements, and instead simply by spacing these profiled elements apart from each other.
  • This mode of realization not only makes it possible to eliminate the step of making the holes, but also ensures greater operational flexibility, since the dimensions of the ventilation/lighting apertures may be defined simply by the dimensions of the profiled elements and the respective spacings.
  • the coupling appendage 30 consists of a single profiled element 31 which has a longitudinal extension substantially equivalent to the longitudinal extension of the elongated body 30.
  • the ventilation and lighting apertures are defined by a plurality of longitudinal slits 41 made on the coupling portion 30a of said single profiled element 31.
  • the aforesaid longitudinal slits 41 are distributed, preferably uniformly, along the longitudinal extension of said single profiled element 41.
  • the coupling appendage 30 consists of two or more separate profiled elements 32, 33, 34 which are arranged at positions spaced apart from each other along said longitudinal engagement seat 13. In so doing, a free space and longitudinal spacing is defined between two profiled elements 32, 33 and 33, 34.
  • the ventilation and lighting apertures are defined by the longitudinal spacings 42 present between the coupling portions 30a of two or more of said profiled elements 32, 33, 34.
  • the aforesaid longitudinal spacings 42 are distributed, preferably uniformly, along the longitudinal extension of said elongated body 41.
  • the ventilation and lighting apertures may be defined not only by the longitudinal spacings 42 but also by a plurality of longitudinal slits made on the coupling portions 30a of two or more of said profiled elements 32, 33, 34.
  • the ventilation and lighting apertures are defined only by the longitudinal spacings 42 present between the coupling portions 30a of two or more of said profiled elements 32, 33, 34.
  • each of said one or more profiled elements 31, 32, 33, 34 comprises an engagement base 30b at which the profiled element 31, 32, 33, 34 is engaged inside said longitudinal seat 13.
  • the coupling portion 30a extends from said engagement base 30b.
  • This engagement base 30b is preferably defined by two wings 30b' and 30b" which are angled with each other and are inserted in two respective branches 13' and 13" of said longitudinal seat 13, which branches are counter-shaped with respect to said two wings.
  • a first wing 30b' (with the respective seat branch 13') extends along the transverse direction Y, while a second wing 30b" (with the respective seat branch 13") extends orthogonally to said first wing 30b'.
  • This configuration makes it possible to create a coupling between the engagement base 30b and longitudinal seat 13 that is more resistant to torsional strains, thus making the engagement of the coupling appendage 30 on the elongated body 10 more stable over time.
  • each of said one or more profiled elements 31, 32, 33, 34 consists of an extruded body, preferably made of metal.
  • each of said one or more profiled elements 31, 32, 33, 34 consists of a portion of sheet metal which is bent and profiled.
  • the elongated body 10 preferably consists of a box-shaped body made by bending and profiling a metal sheet.
  • the subject of the present invention is also a roller shutter comprising a plurality of slats coupled with each other in pairs.
  • Each of said slats is a slat 1 according to the invention, and in particular as described above.
  • the invention achieves numerous advantages, some of which have already been described.
  • the slat 1 for roller shutters according to the invention makes it possible for the ventilation and lighting apertures in the coupling appendages to be created in a simpler manner.
  • the slat 1 for roller shutters according to the invention is also simple and cost-effective to produce.
