(3) FIG. 2 shows a partially sectioned perspective view of the enlarged detail of an articulation joint of two arms, and

(4) FIG. 3 shows it in a different perspective view with some details removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(5) As can be seen from the figures, the roller awning according to the invention is traditional in itself and includes a tubular shaft 2, a support structure 4 of the tubular shaft 2, a sheet 6 (or similar/equivalent covering element) which can be wrapped around the tubular shaft 2 and unrolled from this, a rigid crosspiece 8, to which the edge of the sheet 6 is applied opposite to that constrained by the tubular shaft 2, and two pairs of articulated arms 10,10 which connect the rigid crosspiece 8 to the support structure 4 and they guide its translational movements with respect to it.

(6) The tubular shaft 2 can advantageously be a metal shaft, or made of other material, with a hexagonal or octagonal section or similar, of the type traditionally used for curtains and/or roller shutters.

(7) The tubular shaft 2 can house inside it a traditional tubular motor 12 for rotating the awning, and also the shaft 2 for winding/unwinding the said sheet 6.

(8) The tubular shaft 2 can house inside it a traditional device 14 for powering and controlling a plurality of light sources, in particular LED lights.

(9) Preferably, inside the tubular shaft 2 there is housed a radio receiver or a radio transceiver with driver for controlling the LED outputs, which, in addition to receiving commands for activating/adjusting the LED outputs, can transmit signals on the status of the LEDs themselves, in so that the user can remotely control, via a radio control or even via smartphone or similar, the switching on, off and adjustment of the LEDs and can receive, again with the smartphone or similar, information on the current status of these.

(10) Preferably, said LED lights are made up of LED strips 16 applied to the support structure 4 and/or to the crosspiece 8 and/or to the articulated arms 10.

(11) Preferably, the support structure 4 is essentially made up of a C-shaped bracket, with a central wing 18, at which the structure 4 is fixed to a wall and with two lateral wings 20, which protrude outwards and they are configured to support the tubular shaft 2 and everything contained therein.

(12) Preferably, the crosspiece 8 is made up of a profile with an arched section. Preferably, the crosspiece 8 is provided at the ends with two closing elements 22 having a shape complementary to the shape of the lateral wings 20 of the support structure 4, so that when the crosspiece adheres to this it defines with it a closed container which is housed in its inside the sheet 6 completely wrapped around the tubular shaft 2 and the two pairs of articulated arms 10, 10 completely folded.

(13) Preferably, the articulation joint between the two articulated arms 10,10 of each pair provides that one end of each arm is provided with discs 24,24 centrally perforated and configured so that they can be inserted between them to be crossed by a single pin 26, internally hollow, around which they can articulate. Conveniently, as can be seen from the figures, the pin 26 extends longitudinally and is open at its mutually opposite longitudinal ends; conveniently, as can be seen from the figures, the pin 26 is hollow and, in particular, includes an axial cavity 37 inside it.

(14) In particular, the disks 24,24 are integral with/fixed respectively to the arms 10, 10.

(15) Preferably, in a possible embodiment illustrated in the figures, two disks 24 are integral with the arm 10 while three disks 24 are integral with the arm 10, which in the joint formed are arranged one between the two disks 24 of the arm 10 and two externally to these two discs 24. Preferably, a number of disks are attached to one arm which is one unit greater than the disks of the other arm.

(16) Preferably, the discs 24, 24 are rounded, in particular at their outermost edge, similarly to the longitudinal edges of the arms 10, 10, to give the whole a linear and aesthetically pleasing appearance.

(17) The ends of the hollow pin 26 stop at the two external disks 24. Preferably, the pin 26 is mounted neutrally with respect to all the disks 24 and is instead made integral with at least one of the disks 24 by any traditional means, and in particular by means of screws.

(18) Inside an upper cavity 28, preferably cylindrical shape, obtained in the upper disk 24, at the upper end of the pin 26, a printed circuit board 30 is applied, on which one or more LEDs are mounted, which face the axial cavity 37 of the pin itself.

(19) The printed circuit board 30 is powered via a cable 32, which is fixed or associated with the upper edge of the arm 10 and enters the cylindrical cavity 28. Conveniently, the cable 32 can run along the upper edge of one of the two articulated arms 10 or 10 (which can be the arm to which the upper disc is attached or the other one).

(20) Conveniently, in a possible embodiment not shown, the printed circuit board 30 is provided with a power battery for said at least one LED mounted on the board itself.

(21) Preferably, the cavity 28 is then closed by a removable plug 34 preferably having the shape of a spherical cap, more preferably a flattened spherical cap. Preferably, the plug 34 can be crossed by the cable 32.

(22) Inside the axial cavity 37 of the pin 26 there is a light guide 36, which has the upper end facing the LED fixed to the printed circuit board 30 and the lower end opening at the lower end of the axial cavity 37 of said pin 26.

(23) Preferably, a light diffuser 38 is associated with the lower end of said light guide 36. Preferably, the lower end of the light guide 36 extends into a light diffuser 38. Conveniently, the light diffuser 38 can be single body with the light guide 36 or it can be removably fastened to the light guide 36 and/or to the axial cavity 37 of the pin 26.

(24) Preferably, said light diffuser 38 has the shape of a spherical cap. Preferably, the shape of the light diffuser 38 is similar to the shape of the plug 34 closing the cavity 28.

(25) Advantageously in this way, when the awning is unfolded, the light generated by the LED mounted on the printed circuit board 30 and preferably diffused by the light diffuser 38 creates substantial continuity with the light strips generated by the LEDs 16 applied to the lower edge of the arms 10,10, thus eliminating the inconvenience found in roller blinds with arms equipped with LED strips.

(26) Furthermore, advantageously, the elimination of this drawback is achieved without substantially modifying the traditional conformation of the articulation joints of the arms 10,10 of a traditional roller awning, but simply by replacing the articulation pin of the latter with the hollow pin 26 provided with board 30 provided with LEDs, with light guide 36 and, preferably, with diffuser 38.

(27) This allows you to modify the articulation joint of the arms of a traditional awning with a rather simple operation, which can also be carried out in existing awnings but not provided with this functionality.

(28) Finally, advantageously, the power supply of the LED, which allows the articulation joint between the two arms 10, 10 to perform this new function, is obtained with a cable 32 which runs above one of the arms 10 and that is in position not visible as it is located on the opposite side to that intended for users of the tent.

(29) The present invention has been illustrated and described in some of its preferred embodiments, but it is understood that executive variations may be made to them in practice, without however departing from the scope of protection of the present patent for industrial invention.
