[0001] The present invention concerns an elongated modular element, commonly called "slat", for the production of blinds, shutters, roll-up shutters, wall panels of wardrobes, casings for electrical equipment or similar. A characteristic of the closing elements produced with the modular elements according to the present invention is that in a first adjustment position thereof they allow the passage of air but not light, whereas in a second adjustment position thereof they prevent the passage of both air and light. Therefore said elements are particularly suited to use for the protection of environments in which a certain degree of aeration has to be maintained, but in which the sunlight could cause alteration of the goods contained in them, for example picture galleries, libraries, wineries and similar.
[0003] Further objects and advantages of the present invention will become clearer during the following description thereof, with reference to the attached drawings, in which:
Figure 1 illustrates in perspective, with parts in cross section, a slat for blinds according to a first embodiment of the present invention, in which the component elements of the blind are in the position in which they allow the passage of air but not light.
Figures 2 and 3 illustrate in cross section blind elements obtained by joining several slats (three as illustrated) of the type shown in figure 1.
Figures 4 and 5 illustrate in cross section blind elements obtained by joining several slats (three as illustrated) of the type shown in figure 1, to produce an embodiment of a shutter.
Figures 6 and 7 illustrate in cross section further shutter embodiments similar to those of figures 4 and 5 in which, however, the slat elements of the shutter are able to mutually slide; lastly
Figure 8 illustrates in perspective a further embodiment of slat for shutters according to the invention.
[0004] With reference to the drawings, and with particular reference to figure 1 thereof, the slat 1 in question is formed of two parts 101, 201 which extend longitudinally and are profiled and connected together so as to form between them an S-shaped channel, with reference number 2, which opens on both fronts of the slat. The two parts 101, 201 are maintained integral with each other by means of two sides 3. Furthermore, the slat 1 has on the upper longitudinal side thereof a longitudinal bead 4 and on the lower side a corresponding groove 5. Thus shaped, the slat 1 is particularly suitable for the production of blinds, shutters and similar (see figures 2 and 3). A blind made in this way can therefore prevent the inlet of light and at the same time allow an optimal internal aeration. Preferably, the slat 1 is provided with a control device of the channel 2. As illustrated, said device consists of a shaft 6 which extends throughout the length of the slat 1 and is rotatingly mounted flush with the channel 2, said shaft 6 comprising a bar 7 which can be made to oscillate from a passive position (fig. 2), in which it does not interfere with the channel 2, to an active position, in which it can interfere with the channel 2 so as to limit or even prevent the passage of air (fig. 3) there through. At one end of the single shaft 6 a lever 8 is fixed, the end of which projects a small distance from its slat. The ends of all the levers 8 are engaged in a vertical cursor 9, the manual or mechanized sliding of which causes oscillation of the bar 7.
[0005] In the embodiment of figures 4 and 5, the slat 1 is used to produce roll-up shutters. Overall it has a form similar to that of figures 1 and 2, but comprises above and below deep slots 10 in which two enlargements 12 of a connecting strip 11 slidingly engage, allowing, as in the traditional roll-up shutters, a limited relative movement between each slat. Also this embodiment is preferably provided with a device that controls the aeration channel 2. Said device comprises a sliding bar 13 mounted in the area of the channel 2 and carried at the ends by a pair of plate-like side panels 14. Said side panels 14 are in turn coupled to one of the enlargements 12 of the relative connecting strips 11, so that, with the slats spaced apart, the bar lies in a passive position whereas with the slats adjacent, the bar intercepts the passage of air in the channel 2.
[0006] In the embodiment of figures 6 and 7, the slat 1 has a form similar to that of figures 4 and 5, but its two semi parts 101 and 102 are mounted between the two plate-like sides 15 so as to reciprocally slide. To allow this limited relative movement, the semi part 201 is fixed to the sides 15 by means of the pins 16, whereas the pins 17 of the semi part 101 can slide in the slots 18 correspondingly obtained in the sides 15. In this way, when the slats are moved apart, the channel remains completely open (fig. 6) whereas with the slats adjacent, the semi part 101 drops, due to gravity, onto the semi part 201 occluding the ends of said channel (fig. 7).
[0007] Lastly, according to an embodiment illustrated in fig. 8, the single connecting strip 11 of the slats 1 for roll-up shutters is made with interspaced windows 111 and comprises a plate-like longitudinal cursor 19 also provided with identical windows 20. Obviously a brief sliding of the cursor 19 can lead to a partial or total correspondence of the windows 111, 20 of the two elements 11 and 19, thus permitting a limited passage of light, when the slats of the shutter are moved apart. Naturally, the single strip 11 can be totally obscured, by appropriately operating the cursor 19.

shutters, wall panels of wardrobes, casing for electrical equipment or similar, characterized in that each slat comprises two parts (101, 201) which extend longitudinally and which are
profiled and connected together to form between them an S-shaped channel (2) which
opens on both fronts of the slat and further characterized in that in a first adjustment position of the parts (101, 201), the latter allow the passage
of air and not light, whereas in a second adjustment position, they prevent the passage
