DESCRIPTION OF PREFERRED EMBODIMENTS

(10) The eyelet of the invention is indicated with 1 in FIG. 1 and comprises a first head 2 provided with an element 3, for example a circular ring, from which a cylindrical shaped shank 4 with an inner hole 5 extends. The shank 4 of the first head 2 of the eyelet 1 is in particular intended to pass through the hole 6 of the support 7.

(11) According to the invention, the shank 4 of the first head 2 has two portions, 4a and 4b respectively, where the portion 4b is the one facing the hole 6 of the support 7 to which the eyelet 1 is to be attached. The same portion 4b also has a diameter Db, larger than the diameter Da of the aforesaid portion 4a.

(12) The eyelet of the invention also comprises a second head 8 formed by a ring-shaped element 9, which in turn has an inner shank 10 of lesser height com-pared with the shank 4 of the head 2 and also provided with an inner hole 11.

(13) In a position facing the outer wall 12 of the shank 10, the aforesaid head 8 has a wall element 13 that, in combination with the same wall 12 of the shank 10, defines and forms a groove 14.

(14) When applied to the high thickness support 7 shown in FIGS. 2 and 3, the edge 15 of the portion 4b having a diameter Db larger than the shank 4 of the head 2 is housed inside the groove 14 of the second head 8 thus forming a folded edge 16 that, by interfering with the aforesaid annular element 13 of the head 8, provides the mechanical seal between the heads 2 and 8 of the eyelet 1 on the support 7.

(15) Instead, when applied to the support 17 of FIGS. 4 and 5, which is thinner than the support 7 of the preceding figures, the edge 15 of the portion 4b of the shank 4 of the head 2 forms a folded edge 18 that is formed by a length of shank greater than that deformed when the eyelet is applied to the thicker support 7 of FIGS. 2 and 3.

(16) To this end, the groove 14 of the head 8 will be sized so as to be able to receive the different sizes of the folded edges 16,18 of the shank 4 that are formed in the two types of coupling described above.

(17) Therefore, it can be understood how, due to the invention, the coupling with deformable shank of the head 2 inside the groove 14 of the head 8 allows the size of a single eyelet 1 to be adapted to supports 7 and 17 having different thickness.

(18) Moreover, as can be seen in the aforesaid figures, insertion of the shank 4 of the first head 2 inside the groove 14 of the second head 8, due to the structure of the shank 4 in portions 4a and 4b of different diameter, maintains the continuity between the coupled inner surfaces, the inner surface 25 of the portion 4a of shank 2 and the inner surface 26 of the shank 10, respectively. In this way insertion of a cap or other closing accessories inside the hole 11 of the shank 10 is facilitated.

(19) The plan view of the eyelet of the invention on a support 7 or 17 is shown in FIG. 6.

(20) In the mode of application of the eyelet of the invention illustrated in FIG. 7, the edge 19 of the shank 10 of the head 8 has faceted portions 20, designed to cooperate with the outer wall 21 of the shank 22 of a cap-shaped head 23 that identifies a closing device of the hole 11 of the eyelet 1.

(21) In particular, said cap-shaped head 23 has a visible cap 24, with ornamental patterns.

(22) In use, the shank 22 of the cap-shaped head 23 is inserted into the hole 11 of the second head 8 of the eyelet applied to the support 7 or 17. According to the invention, the aforesaid insertion is facilitated by the described structural continuity between the contiguous walls 25 and 26, of the portion 4a of shank 4 of the head 2 and of the shank 10 of the head 8, respectively.

(23) Forced engagement of the shank 22 in the aforesaid hole 11 produces the interference of the wall 21 of the same shank 22 with the facets 20 of the edge 19 of the shank 10 of the second head 8, thus preventing accidental relative rotations of the cap-shaped head 23 inside the eyelet 1, susceptible of modifying the orientation of the cap 24 with the ornamental pattern.

(24) The diameter of the shank 22 of the cap-shaped head 23 will also be proportionate to the corresponding diameter of the hole 11 of the shank 10 of the second head 8, so as to allow not only coupling between these parts, but also easy extraction of the same cap-shaped head 8 from the eyelet 1, thus allowing the desired replacements of the cap-shaped head.

(25) In the variant illustrated in FIG. 11, the ring 9a and the annular element 13a, both of the head 8, are provided as separate components and not in one piece.

(26) The invention, as described above and illustrated in the accompanying drawings, can be modified to produce variants, which nonetheless fall within the scope of the claims below.

(27) Thus, for example, the overall shape of the eyelet of the invention and of the related components can be other than circular, for example it can be oval, polygonal and the like.

(28) Moreover, the facets 20 on the edge 19 of the shank 10 of the second head 8 can be replaced with different components which are nonetheless capable of engaging on the shank 22 of the cap-shaped head 23, in order to prevent relative rotations.

(29) To this end, it is possible to use projecting inner teeth, notches on the edge 19 of the shank 10, knurls and the like.
