A joint for furniture structures which comprise first tubular elements (3) and a second tubular element (5) which are angularly arranged to one another. The joint (100) comprises: a main connecting element (1) which affords a first seating (11A) and a second seating (11B) which extend in opposite directions and are internally provided with respective first coupling organs (12); at least a pair of terminal connecting elements (2), associated to terminal portions of the first tubular elements (3) and externally provided with respective second coupling organs (21) which are complementary to the first coupling organs (12), and which pair of terminal connecting elements (2) respectively interest the first seating (11A) and the second seating (11B) to enable a reciprocal coupling of the first tubular elements (3) in a predetermined direction (L) and to define a perimeter opening (4) in a coupling zone between each seating (11A,11B) and a relative terminal connecting element (2); a second connecting element (51), internally associated to a terminal portion of the second tubular element (5), being provided with third coupling organs (52) for partially engaging the perimeter opening (4) and consequently enabling an engaging of the second tubular element (5) to a group defined by the first tubular elements (3), the main connecting element (1) and the terminal connecting elements (2).
1). A joint for furniture structures, comprising at least first tubular elements (3) and at least a second tubular element (5) which are angularly arranged to one another, characterised in that it comprises:
2). The device of claim 1, characterised in that the first coupling organs (12) are female coupling organs, and in that the first female coupling organs (12) are constituted by a female bayonet coupling.
3). The device of claim 1, characterised in that the second coupling organs (21) are male coupling organs, and in that the male coupling organs (21) are constituted by a male bayonet coupling.
4). The device of claim 1, characterised in that the third coupling organs (52) are constituted by an element provided with a central body (54) which rotatably bears, on opposite lateral sides thereof, a first jaw (52A) and a second jaw (52B), relative ribs (53A, 53B) of which first jaw (52A) and second jaw (52B) partially engage the perimeter opening (4).
5). The device of claim 4, characterised in that the first seating (11A) and the second seating (11B) exhibit external edges having a countersink (15) which facilitates coupling of the ribs (53A, 53B) and the main connecting element (1).
6). The device of claim 1, characterised in that the main connecting element (1) is cylindrical.
7). The device of claim 1, characterised in that the first seating (11A) and the second seating (11B) are cylindrical.
8). The device of claim 1, characterised in that the terminal connecting element (2) is cylindrical.
9). The device of claim 1, characterised in that the first tubular elements (3) exhibit a circular section.
10). The device of claim 1, characterised in that the second tubular element (5) exhibits a rectangular section.
11). The device of claim 4, characterised in that it comprises a spring (56) interposed between the central body (54) and each of the jaws (52A, 52B).
12). The device of claim 11, characterised in that it includes stabilising organs (59), associated to the jaws (52A, 52B) and coming into contact with the central body (54), which stabilising organs (59) block the jaws (52A, 52B) in a predetermined angular position with respect to the central body (54).
13). The device of claim 12, characterised in that the stabilising organs (59) are constituted by a pair of grub screws (59A, 59B).
14). The device of claim 13, characterised in that the second tubular element (5) affords a through hole (78) on opposite walls thereof for enabling access of a tool for turning the grub screws (59A, 59B).
