DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] With reference to the accompanying tables of drawings, reference numeral (1) denotes in its entirety a fastening element for fixing a plurality (2) of sound-absorbent panels to an upright (3) of the present invention. Further, reference number (100) denotes in its entirety a sound-absorbent barrier for a communication pathway, also an object of the present invention.

[0015] The fastening element (1) is suitable for fixing a plurality (2) of sound-absorbent panels to an upright (3), for realising a sound-absorbent barrier (100) along a communication pathway.

[0016] With particular reference to figures 15-17, the upright (3) comprises a coupling portion (4) which is conformed as a bar and a sound-absorbent and/or sound-insulating panel (5, 6) of the plurality (2) of sound-absorbent and/or sound-insulating panels comprises a lateral wall (50, 60) which is provided with a projection (51) or a recess (61).

[0017] With reference to figures 1-12, the fastening element (1) comprises: a plate (10) which affords a through-opening (11), which through-opening (11) originates from a first flank (10a) of the plate (10) and is conformed for receiving a coupling portion (4) of the upright (3) so as to constrain the plate (10) to the upright (3); an anchoring portion (12) which is C-shaped, which originates from a second flank (10b) of the plate (10) and which is dimensioned such that when the fastening element (1) and the sound-absorbent and/or sound-insulating panel (5, 6) are assembled, it internally contains the projection (51) or is contained internally of the recess (61) of the sound-absorbent and/or sound-insulating panel (5, 6) so that the sound-absorbent and/or sound-insulating panel (5, 6) is fixed to the upright (3). Therefore the fastening element (1) of the present invention enables a rapid and flexible fixing of a sound-absorbent and/or sound-insulating panel (5, 6) to an upright (3) (see figure 16).

[0018] However, the fastening element (1) is able to fix more than one sound-absorbent and/or sound-insulating panel (5, 6) to an upright (3).

[0019] In fact, in a case in which a first sound-absorbent and/or sound-insulating panel (5) of the plurality (2) of sound-absorbent and/or sound-insulating panels comprises a lateral wall (50) which is provided with a projection (51), a second sound-absorbent and/or sound-insulating panel (6) of the plurality (2) of sound-absorbent and/or sound-insulating panels comprises a lateral wall (60) which is provided with a recess (61) and the first sound-absorbent and/or sound-insulating panel (5) and the second sound-absorbent and/or sound-insulating panel (6) are conformed in such a way then when assembled to one another, the projection (51) is contained internally of the recess (61) and therefore the disclosed fastening element (1) is able to fix both the first sound-absorbent and/or sound-insulating panel (5) and the second sound-absorbent and/or sound-insulating panel (6) to the upright. In particular, the anchoring portion (12) is dimensioned so that when the fastening element (1), the first sound-absorbent and/or sound-insulating panel (5) and the second sound-absorbent and/or sound-insulating panel (6) are assembled, it internally contains the projection (51) of the first sound-absorbent and/or sound-insulating panel (5) and is contained internally of the recess (61) of the second sound-absorbent and/or sound-insulating panel (6), so that the first sound-absorbent and/or sound-insulating panel (5) and the second sound-absorbent and/or sound-insulating panel (6) are both fixed to the upright (3) (see figure 15).

[0020] The anchoring portion (12) is C-shaped and identifies, therefore, an internal surface (120) of the anchoring portion (12) and an external surface (121) of the anchoring portion (12) (figure 15).

[0021] It is specified that, with reference to figures 15-17, when the fastening element (1), the first sound-absorbent and/or sound-insulating panel (5) and the second sound-absorbent and/or sound-insulating panel (6) are assembled, the fact that the C-shaped anchoring portion (12) internally contains the projection (51) of the first sound-absorbent and/or sound-insulating panel (5) means that the anchoring portion (12) embraces the projection (51), i.e. that the internal surface (120) of the anchoring portion (12) faces the projection (51). The internal surface (120) of the anchoring portion (12) can contact the projection (51).

[0022] It is further specified that, with reference to figure 15, when the fastening element (1), the first sound-absorbent and/or sound-insulating panel (5) and the second sound-absorbent and/or sound-insulating panel (6) are assembled, the fact that the C-shaped anchoring portion (12) is contained internally of the recess (61) of the second sound-absorbent and/or sound-insulating panel (6) means that the anchoring portion (61) embraces the projection (12), i.e. that the external surface (121) of the anchoring portion (12) faces the projection (61). The external surface (121) of the anchoring portion (12) can contact the recess (61).

[0023] The anchoring portion (12) preferably comprises: a first fin (12a) which originates perpendicularly from the second flank (10b) of the plate (10); a second fin (12b) which originates perpendicularly from the first fin (12a) and which develops externally with respect to the plate (10); and a third fin (12c) which originates perpendicularly from the second fin (12b) and which faces the first fin (12a).

[0024] The projection (51) of the sound-absorbent and/or sound-insulating panel (5, 6), or the recess (61) of the sound-absorbent and/or sound-insulating panel (5, 6) can have a complementary shape to the anchoring portion (12).

[0025] The coupling portion (4) of the upright (3) and the through-opening (11) made in the plate (10) are preferably reciprocally conformed so as to realise, when the plate (10) and the upright (3) are constrained, a form coupling.

[0026] For example, with reference to figures 1 and 2, the coupling portion (4) of the upright (3) comprises a first lateral wall (40), a second lateral wall (41) and a third lateral wall (42). Likewise, the through-opening (11) is delimited by a first abutment wall (11a), a second abutment wall (11b) and a third abutment wall (11c) and receives the coupling portion (4) in such a way that the first abutment wall (11a) can abut the first lateral wall (40), the second abutment wall (11b) can abut the second lateral wall (41) and the third abutment wall (11c) can abut the third lateral wall (42).

[0027] Likewise, also with reference to the embodiments of the fastening element (1) of figures from 3 to 12, the coupling portion (4) of the upright (3) has a complementary shape to the walls that delimit the through-opening (11). Further, in accordance with the embodiments illustrated in the figures, the through-opening (11) can be delimited by a projecting wall which originates from the plate (10) and projects from the plate (10).

[0028] The constraint between the coupling portion (4) of the upright (3) and the plate (10) is advantageously more stable.

[0029] The coupling portion (4) of the upright (3) and the through-opening (11) made in the plate (10) are preferably reciprocally conformed so that when the fastening element (1) and the upright (3) are constrained, the plate (10) can slide along the extension direction of the upright (3).

[0030] The assembly is advantageously easier and more flexible.

[0031] The fastening element (1) comprises an abutting portion (13) for abutting the coupling portion (4) of the upright (3), which abutting portion (13) originates from a flank of the plate (10) which is opposite the second flank (10b) of the plate (10) (figures 15-17).

[0032] The abutting portion (13) advantageously increases the fixing stability of the sound-absorbent and/or sound-insulating panel (5, 6) to the upright (3), when the fastening element (1) and the sound-absorbent and/or sound-insulating panel (5, 6) are assembled.

[0033] In accordance with the embodiments illustrated in figures 4-6 and 10-12, the first flank (10a) of the plate (10) and the second flank (10b) of the plate (10) are opposite one another and the abutting portion (13) originates from the first flank (10a) of the plate (10).

[0034] Alternatively, according to the illustrated embodiments in figure 1-3 and 7-9, the first flank (10a) of the plate (10) and the second flank (10b) of the plate (10) are adjacent and the abutting portion (13) originates from a third flank (10c) of the plate (10), which third flank (10c) of the plate (10) is opposite the second flank (10b) of the plate (10) and is adjacent to the first flank (10a) of the plate (10).

[0035] The abutting portion (13), in accordance with the figures of the drawings, can comprise: a first fin (13a) which originates perpendicularly from a flank of the plate (10); a second fin (13b) which originates perpendicularly from the first fin (13a) and which develops internally towards the plate (10); an abutting fin (13c) which originates perpendicularly from the second fin (13b).

[0036] This conformation of the abutting portion (13) advantageously gives greater rigidity to the structure of the fastening element (1).

[0037] The abutting fin (13c) of the abutting portion (13) preferably develops externally with respect to the plate (10).

[0038] With reference to the embodiments of the fastening element (1), illustrated in figures 1-3 and 7-9, it is specified that the fastening element (1) enables fixing of at most two sound-absorbent and/or sound-insulating panels to the upright (3). In particular, the fastening element (1) can fix one only sound-absorbent and/or sound-insulating panel (5, 6) to the upright (3) (for example if the panel is located at the top of the barrier) or can fix the first sound-absorbent (5) panel and the second sound-absorbent panel (6) to the upright (3), arranged one superiorly of the other.

[0039] With reference to the embodiments of the fastening element (1), illustrated in figures 4-6 and 10-12, it is specified that the fastening element (1) enables fixing of at most four sound-absorbent and/or sound-insulating panels to the upright (3). In particular, the fastening element (1) can fix the first sound-absorbent and/or sound-insulating panel (5) and a further first sound-absorbent and/or sound-insulating panel (5') to the upright (3) arranged flanked (for example they are positioned at the top of the barrier). Otherwise, the fastening element (1) can fix, to the upright (3), the first sound-absorbent and/or sound-insulating panel (5), a further first sound-absorbent and/or sound-insulating panel (5') arranged flanked to the first sound-absorbent and/or sound-insulating panel (5), the second sound-absorbent and/or sound-insulating panel (6) arranged above or below the first sound-absorbent and/or sound-insulating panel (5) and a further second sound-absorbent and/or sound-insulating panel arranged flanked to the second sound-absorbent and/or sound-insulating panel (6) and arranged above or below the further first sound-absorbent and/or sound-insulating panel (5').

[0040] The fastening element (1) can further comprise a through-hole (15) fashioned in the abutting portion (13) (for example, fashioned in the abutting fin (13c)). The through-hole (15) has a function only in a case in which the sound-absorbent and/or sound-insulating panel to be fixed is arranged at the top of the sound-absorbent barrier (100). In this case, in fact, the through-hole (15) serves for stabilising the fixture by means of a system of nuts and bolts which engages the through-hole (15) and is fixed to the upright (3).

[0041] The fastening element (1), according to any one of the embodiments thereof, can be obtained by moulding.

[0042] The fastening element (1) is, preferably, made of a metal material.

[0043] With reference to figures 13, and 14, different embodiments are illustrated of a sound-absorbent and/or sound-insulating barrier (100) for a communication pathway of the present invention. In particular, the sound-absorbent and/or sound-insulating barrier (100) comprises: a plurality (30) of uprights fixable along a communication pathway; a plurality (2) of sound-absorbent and/or sound-insulating panels; a plurality (50) of fastening elements in which each fastening element (1) is in accordance with one of the above-described embodiments.

[0044] The sound-absorbent and/or sound-insulating barrier (100) of the invention is advantageously easy and simple to assemble, is stable and is such as to have a good aesthetic impact as the plurality (30) of uprights are not visible to persons travelling along the communication pathway, being covered by the plurality (2) of sound-absorbent and/or sound-insulating panels.

[0045] The sound-absorbent and/or sound-insulating panels of the plurality (2) of sound-absorbent and sound-insulating panels can be of a type comprising an external metal sheet (for example steel or aluminium) internally containing a layer of sound-absorbent and or sound-absorbent material (figure 15) or can be of a type made of concrete, or of other materials (for example plastic, wood or glass).

[0046] In particular, in a case in which the sound-absorbent and/or sound-insulating panels are made of glass, they will be such as to comprise a lateral wall that is provided with a recess.

[0047] The sound-absorbent and/or sound-insulating barrier (100) can comprise sound-absorbent and/or sound-insulating panels all made of the same material, or of different materials.
