DETAILED DESCRIPTION OF THE INVENTION

The elements or parts of elements common to the embodiments described below will be indicated using the same reference numerals.

With reference to the aforesaid drawings, reference numeral 4, 4′ globally denotes a section, in particular for structures 8, having a main longitudinal extension X-X from a first to a second end 12, 16.

The section 4 has, in proximity of at least one of said ends 12, 16, a coupling element 20 suitable to engage with a further section 4″.

The section 4 comprises a rib 24 and a plate 28 positioned perpendicular to the rib 24 so as to form an overall “T” section.

Preferably the rib 24, on the side opposite the plate 28, comprises a longitudinal stiffening element 42.

The rib 24 comprises at least one engagement aperture 36 shaped to house said coupling element 20 and positioned between said first and second ends 12,16.

The coupling element 20 comprises an attachment base 40 to the rib 24 which projects at least partially from the section 4 with a free end 44, and a tongue 48 elastically flexible and connected to the attachment base 40.

For example, the attachment base 40 is attached to the rib by riveting, welding, gluing and/or threaded connection means.

Advantageously, the tongue 48 is bent towards the attachment base 40, at said free end 44 so as to form an angle of incidence with the attachment base 40.

The tongue 48 is provided with a coupling hole 52, and the engagement aperture 36 defines at least a first tooth 56 suitable to engage with the coupling hole 52 of the flexible tongue 48.

According to one embodiment, the engagement aperture 28 has a first pair of guides 60 positioned on opposite sides to the first tooth 56, and said coupling element 20 has a first pair of tabs 64 overhanging the attachment base 40; said guides 60 co-operate so as to slide with the tabs 64 to guide the engagement of the coupling element 20.

According to a further embodiment, the engagement aperture 36 defines at least a second tooth 68, opposite the first tooth 56 in relation to a centreline plane M-M of the engagement aperture 36 orthogonal to the main longitudinal extension X-X, to permit the contemporary restraint of two coupling elements 20 of two separate sections 4′, 4″.

According to a further embodiment, the engagement aperture 36 has a second pair of guides 72 positioned on opposite sides to the second tooth 68, to permit the guided engagement of two coupling elements 20 of two separate sections 4′, 4″.

Preferably, said centreline plane M-M is also a plane of symmetry for the engagement aperture 36.

The free end 44 of the attachment base 40 preferably has a pair of shoulders 76 which define a limit stop in the insertion of the attachment element 20 inside the engagement aperture 36, said shoulders 76 abutting against the rib 24.

The free end 44 may have a pair of bevelled drafts 80 to facilitate insertion of the attachment element 20 inside the engagement aperture 36.

The sections 4, 4′, 4″ of the present invention may advantageously be assembled to each other to form a structure 8, in particular to support false ceilings.

Said structure 8 (FIGS. 4, 6) comprises a plurality of sections 4, 4′,4″ mechanically connected to each other so that the attachment element 20 of a first section 4′ engages in the engagement aperture 36 of a second section 4″.

As may be appreciated from the description, the section according to the invention makes it possible to overcome the drawbacks presented in the prior art.

In particular, the section is economical and simple to produce.

In addition, the section guarantees a reliable mechanical connection and stability of the structure obtained by the interconnection of such sections.

A person skilled in the art may make numerous modifications and variations to the sections described above so as to satisfy contingent and specific requirements, all contained within the sphere of the invention as defined by the appended claims.
