DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0037] With particular reference to the figures described above, the spacer device for slats of rolling shutters or rolling gates according to the present invention is designated, as a whole, by the reference number 1.

[0038] The spacer device 1 is applied to rolling shutters or rolling gates that slide in a first and a second vertical guides (not represented) opposed to one another.

[0039] The device 1 comprises a first and a second connecting rods, designated as a whole by the numeral 2, each having at least one first slot that, preferably but not necessarily, has a partition 15 that divides the slot into a first and a second half-slot 3 and 4, which engage, respectively, first and second pins designated generically by numerals 5 and 6.

[0040] The first half-slot 3 is connected via the first pins 5 inside first seats 7 present on the opposed faces 8 and 9 of a first slat 10.

[0041] The second half-slot 4 is connected via the second pins 6 inside second seats 16 present on the opposed faces 17 and 18 of a second slat 19.

[0042] The first and second pins 5 and 6 each have a stem 20 having a first end 21 that engages in first and second housings 22 present, respectively, on first and second caps 23 and 24 closing the opposed faces 8 and 9 and 17 and 18 of the first and second slats 10 and 19.

[0043] The stem 20 has a second end 25, opposite to the first end, which engages in the first and second seats 7 and 16.

[0044] In particular, in a preferred solution, the first end 21 has a widened head 26, having a cylindrical shape that mates with that of the first and second housings 22 so that it can be withheld by the latter both radially and axially.

[0045] Each stem 20 has, beside the head 26, an annular thickened portion 27 having a diameter larger than that of the first and second seats 7 and 16 and a length greater than the thickness of the first and second half-slots 3 and 4.

[0046] In this way, the stem is housed inside the first and second seats 7 and 16 as far as the annular thickened portion 27, which functions as spacer between the opposed faces of the slats 10 and 19 in such a way as to enable the first and second connecting rods 2 to move freely and without friction with respect to the slats 10 and 19.

[0047] Moreover, the annular thickened portion thus structured engages in the first and second half-slots 3 and 4, guaranteeing a greater resistance to shear stresses and friction that are exerted thereon by the connecting rods during movement of the rolling shutter.

[0048] To guarantee perfect winding on the winding roller, both the first and the second connecting rods 2, together with the first and second caps 23 and 24, have a radius of curvature equal to that of the slats.

[0049] In addition, in order to enable perfect contact between the slats when the rolling shutter is totally closed, the first and second connecting rods 2 have a length shorter than the height of each of the slats themselves.

[0050] Advantageously, moreover, the first and second caps each have two wings 30 and 31, present on which are the housings 20 and, in a central position, a projection 33, which extends orthogonally from the wings and is designed to engage with a central seat 34 of the first and second slats 10 and 19.

[0051] The caps are fixedly connected in the seats 34 via a self-tapping screw (not represented), and simultaneously perform various functions.

[0052] In the case where the pins 5 and 6 are rotatably housed in the seats 7 and 16, each cap has the function, not only of closing the slats, but also of preventing the pins from slipping out of them, also guaranteeing a possible rotation movement thereof during movement of the connecting rods so as to reduce friction on the annular thickened portion.

[0053] In the case, instead, where the pins are housed with interference in the respective seats, the caps have, not only the function of closing the slats, but also that of preventing them from undergoing bending, thus avoiding friction due to undesired contacts and guaranteeing a greater duration thereof.

[0054] The spacer device for slats of rolling shutters or rolling gates thus conceived may undergo modifications and variations, all of which fall within the inventive idea; moreover, the materials used may be any according to the needs.
