DESCRIPTION

Field of the invention
The present invention relates to an articulated arm for arm awnings and an awning comprising said arm. The present invention preferably but not exclusively finds application within the field of sun awnings, usually for outdoor spaces, which comprise two or more jointed or articulated arms, wherein said arms serve the function of allowing the opening of the awning, allowing its inclination and also of supporting the awning.

Background of the invention
Articulated arms for sun awnings have been known for a long time.
For example, the patent EP1650373 illustrates an articulated arm for sun awnings that comprises an arm and a forearm jointed together by means of an articulated joint. The arm has an end fastened by means of an articulated joint to a fixed support and an opposite end fastened by means of an articulated joint to an end of the forearm. The other end of the forearm is connected to a bar. The awning extends between the fixed support and the bar.
Articulated arms comprising lighting systems are also known. Such lighting systems usually consist of lights, for example arrays of LEDs, which are mounted outside the arm and the forearm with the related power supply cables that run, visible, along the forearm and the arm to the fixed support to be able to connect them to an electrical power supply. Also known are articulated arms in which the power supply cables are made to run partially inside the arm and the forearm but that at the articulated joint between arm and forearm remain visible forming a bend that hangs down when the arm is extended because it has to be able to allow the arm to bend freely.

Summary
In this field, the Applicant has observed that known articulated arms can be improved according to different aspects, in particular with reference to the structure, management and arrangement of the lighting systems and, more in general, of electric users mounted on the arm.

Detailed description
With reference to the aforementioned figures, the reference numeral 1 designates in its entirety an awning with articulated arms provided with two articulated arms 2 in accordance with the present invention.
The awning 1 comprises a box 3 mounted on the wall P of a building. The box 3 is provided with a crosspiece 4. Each of the two articulated arms 2 has its own end fastened to the wall P by means of an articulated connection 5 (more visible in Figure 2) and elements of the box not shown in detail and an opposite end fastened to the crosspiece 4 by means of connecting elements 6 (more visible in Figure 2). An awning 7 is wound on a roller in the box 3 and it is fastened to the crosspiece 4.
The two articulated arms 2 are symmetrical, therefore only one of them will be described below.
The articulated arm 2 comprises an arm 8 and a forearm 9 connected to each other by an articulated joint 10.
The arm 8 has a first end provided with a first part 11 of the articulated joint 12 and a second end, opposite to the first, having the aforementioned articulated connection 5. The forearm 9 has a first end provided with a second part 12 of the articulated joint 11, and a second end, opposite to the first, having the connecting elements 6 to the crosspiece 4.
As is more visible in Figure 3, the first part of the articulated joint 10 comprises a first plate 13, a second plate 14 and a lug 15 constituted by a single body. The first plate 13 and the second plate 14 are circular, coaxial to a rotation axis "X" and axially distanced from each other. The lug 15 has a prevalent development along an orthogonal direction to the axis of rotation "X". The first plate 13 and the second plate 14 have holes that are coaxial to the rotation axis "X".
As is more visible in Figures 2 and 3, the second part of the articulated joint 12 comprises a first plate 16, a second plate 17 and a lug 18 constituted by a single body. The first plate 16 and the second plate 17 are circular, coaxial to a rotation axis "Y" and axially distanced from each other. The lug 18 has a prevalent development along an orthogonal direction to the axis of rotation "Y". The first plate 16 and the second plate 17 have holes that are coaxial to the rotation axis "Y".
When the articulated joint 10 is assembled, as in Figures 2, 4-7, the rotation axes "X", "Y" coincide and a pin 19 coaxial to the axis of rotation "X" or "Y" is inserted through in the holes of the plates to allow a relative rotation between the first and the second part 11, 12 around said rotation axis. Moreover, the first plate and the second plate 13, 14 of the first part 11 are located in an axially inner position with respect to the first and second plate 16, 17 of the second part 12. In other words, the first plate and the second plate 16, 17 of the second part 12 are contained between the first and the second plate 13, 14 of the first part 11.
The arm 8 further comprises a first tubular section 20 connected to the first part 11 of the joint 10. In particular, the lug 15 of the first part 11 is inserted and locked in the first tubular section 20. The arm 8 comprises a second tubular section 21 connected to the second part 12 of the joint 10. In particular, the lug 18 of the second part 9 is inserted and locked in the second tubular section 21.
The articulated joint 10 allows the relative motion between the arm 8 and the forearm 9 between an extended position of the arm 2 (Figures 2, 4 and 6) and a folded position (Figures 5 and 7).
As shown in Figure 8, the second tubular section 21 has a cross section that tapers downwards (when the arm 2 is assembled) so as to define an inclined lower outer wall 22. With reference to the orientation of Figure 8, the second tubular section 21 has an upper wall 23, two slightly curved lateral walls 24, 25 and the inclined lower outer wall 22 that mutually connects lower appendages of the two lateral walls 24, 25 and is inclined also with respect to the upper wall 23. The second tubular section 21 also has a dividing inner wall 26 delimiting a main volume 27 and an auxiliary conduit 28, preferably smaller in size than the main volume 27.
The first tubular section 20 is substantially identical to the second tubular section 21 that was just described (they may have different lengths).
In the inclined lower outer wall 22 of the second tubular section 21 is obtained an opening 29, preferably obtained by milling, which is elongated along the longitudinal development of the second tubular section 21 and opens in the auxiliary conduit 28.
Said opening 29 is configured to house a light source, preferably an array of led lamps, not shown, oriented inwardly.
In a variant not illustrated herein, the opening and the light source can also be mounted on the arm 8.
When the awning 1 is in operation, as shown in Figure 9, the inclined lower outer wall 22 and the lamp are inclined downwardly and toward a central area under said awning 1 and the light "L" is addressed towards a central area of the awning 1.
As is better visible in Figure 6, the first plate 13 of the first part 11 of the articulated joint 10 has a portion that develops around the rotation axis "X", "Y" and delimits an annular housing 30 oriented towards the exterior of the articulated joint 10. The annular housing 30 is a recess obtained in the first plate 13 and that develops around the pin 19.
As shown in Figures 4, 6 and 7, the first part 11 of the joint 10 comprises a first passage 31 communicating with the interior of the first tubular section 20 and communicating with the annular housing 30. Similarly (Figures 3 and 6) and the second part 12 of the joint 10 comprises a second passage 32 communicating with the interior of the second tubular section 21 and communicating with the annular housing 30.
The auxiliary conduit 28 of the first and of the second tubular section 20, 21, the annular housing 30 and the first and the second passage 31, 32 house a power supply cable 33 (Figures 6 and 7) which from the lamps runs along the articulated arm 2 to, for example, an electric power supply of the building.
Starting from the lamp positioned in the opening 29, the power supply cable 33 passes through the auxiliary conduit 28 of the second tubular section 21, enters the second passage 32, then the annular housing 30, where it forms a turn around the pin 19 and to the rotation axis "X", "Y" (figures 6 and 7), and then enters the first passage 31 and thence the auxiliary conduit 28 of the first tubular section 20.
The length of the portion of the power supply cable 33 positioned in the annular housing 30 and arranged as a turn is such that the articulated arm 2 can move between a folded position (wherein arm 8 and forearm 9 lie next to each other, Figure 7) and an extended position (wherein arm 8 and forearm 9 are substantially aligned with respect to each other, Figure 6) without hindering said motion and without damaging the cable 33.
The articulated arm 2 according to the invention further comprises a cover 34 configured to close the annular housing 30 with respect to the outside.
Connecting devices 35, 36 are operatively interposed between the portion with the annular housing 30 and the cover 34 and are configured to allow the application or removal, preferably with bare hands, of the cover 34, without further disassembling the articulated joint 10 or other parts of the articulated arm 2.
In the illustrated embodiment, the connecting devices 35, 36 are magnetic and comprise a magnet or ferromagnetic material 35 brought to the cover 34, at a central portion of the cover 34, and ferromagnetic material or a magnet 36 positioned at the center of the annular housing 30. In other embodiments, not shown herein, the connecting devices can be of another type, for example they comprise a screw or a fitting or a snap-on engagement.
When the arm 2 is assembled, the cover 34 is oriented downward, to allow an easy access from underneath the awning 1.
As is shown in Figures 10 and 11, the articulated arm 2 comprises an elastic element 37 that connects the arm 8 and the forearm 9 to each other, is positioned at least in part inside the first tubular section 20 and serves the function of holding the articulated arm 2 in the extended position.
In the illustrated embodiment, the elastic element 37 is a helical spring that has an end connected to the second part 12 of the joint 12, by means of a strip or band 38 provided with a cylinder 39 housed in a seat, not shown, obtained in said second part 12. An opposite end of the spring 37 is anchored to the arm 8 at a terminal element 40 of said arm 8 opposite to that of the articulated joint 10, by means of a traction bar 41. The terminal element 40 is a part of the articulated connection 5.
In the embodiment of Figure 10, the traction bar 41 has a slot 42 that engages with a pin 43 integral with the terminal element 40 of the arm 8.
In particular, the traction bar 41 has an end connected to the spring 37, an opposite end configured to be engaged by a machinery that is able, by appropriately fastening the arm 2, to pull the spring 37 and elongate it, of an intermediate portion provided with the aforesaid slot 42 and a thinner weakened area 44 positioned at the slot 42.
The described structure allows to mount the spring 37 in the articulated arm 2 as detailed below.
A first end of the spring 37 is fastened to the traction bar 41 and a second end of the same spring 37 is fastened to the band 38. The traction bar 41 with the spring 37 and with the band 38 is inserted in the arm 8, i.e. through the first part 11 of the articulated joint 10, through the first tubular section 20 and also through the terminal element 40 until the traction bar 41 projects slightly from the second end of the arm 8.
The cylinder 39 is housed in the seat obtained in the second part 12 of the articulated joint 11.
The articulated arm 2 is locked and, through the aforementioned machinery that engages the traction bar 41, for example at an eyelet 45, the traction bar 41 is pulled, in contrast to the spring 37, extracting it in part from the arm 8 until bringing the slot 42 to the pin 43 and inserting said slot 42 on the pin 43 (as shown in Figure 10).
At this point, with the spring 37 installed and under tension, an excess portion of the traction bar 41 that projects from the second end of the arm 8 is bent at the weakened area 44 until breaking it. The excess portion is eliminated while the rest of the traction bar 41 remains in place as a component of the articulated arm 2.
In the embodiment of Figure 11, instead of the slot 42 that engages on the pin 43, a seat 46 is shaped in the terminal element 40 of the arm 8. Said seat is configured to house and lock, in contrast to the traction exerted by the spring 37, an edge 47 of the traction bar 41 proximate to the weakened area 44.
