Abstract

A component of a frame for eyeglasses includes a body made of composite material, the peculiarity of which relates to the body having at least one first region and at least two second regions. The first region includes a three-dimensional shape with at least two dimensions that are larger than the dimensions of the at least two second regions. Thus, the configuration defines, along the body, portions with different flexibilities.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Further characteristics and advantages of the disclosure will become more apparent from the description of preferred, but not exclusive, embodiments of the component of a frame for eyeglasses according to the present disclosure, which are illustrated by way of non-limiting example in the accompanying drawings, wherein:

(2) FIG. 1 is a view from above of the component of a frame for eyeglasses, identified by a temple for an eyeglass frame, according to a first embodiment of the present disclosure;

(3) FIG. 2 is a side elevation view of the temple according to the present disclosure; and

(4) FIG. 3 is a plan view from above of a second embodiment of the disclosure, identified by an upper bar of the front of an eyeglass frame.

DETAILED DESCRIPTION OF THE DRAWINGS

(5) With reference to the figures, the component of a frame for eyeglasses, generally designated by the reference numeral 1 for the first embodiment, comprises a rod-like body 2, which in the case of FIG. 1 is shown to be a temple of an eyeglass frame, which has the peculiarity of having at least one first region 3 with a three-dimensional shape that has at least two dimensions that are larger than the dimensions of at least two second regions 4, 5 of the body 2, so as to define, along the rod-like body 2, portions with different flexibilities (i.e. with different stretch modulus).

(6) The component of a frame illustrated is made of composite materials which comprise reinforcement fibers, including carbon fibers.

(7) The definition “first region 3” in this case defines a region 3 that has, as has been said, a three-dimensional shape structure, and in more detail, that has a thickness and a height (the length should be understood as the dimension defined along the longitudinal extension of the rod-like body 2).

(8) Therefore, the first region 3 is a region provided with both a greater thickness, and a greater height than the remaining portions of the body 2.

(9) This ensures that the first portion 3 has a higher rigidity than the remaining portions of the body 2.

(10) The first region 3 has a transverse cross-section that can assume various shapes, indicatively and non exhaustively, triangular, circular, elliptical, rhomboid.

(11) The at least two second regions 4 and 5 of the rod-like body 2 can have lengths that are identical or mutually different.

(12) It is furthermore possible to have more than one region 3 of greater thickness and height than the remaining regions 4 and 5.

(13) The lower rigidity of the regions 4 and 5 is due to the lower thickness and height (and thus cross-section) of such regions with respect to the at least one first region 3, in order to make it possible to shape the body 2 according to the shape of the head of the user.

(14) The cross-sections of the regions 4 and 5 can be identical or different, in the same way as the lengths, as previously described.

(15) The number of regions 4 and 5 can exceed two and be for example three.

(16) To sum up, there are substantially four cases:

(17) a) regions 4 and 5 with identical cross-sections and identical lengths;

(18) b) regions 4 and 5 with identical cross-sections and different lengths;

(19) c) regions 4 and 5 with identical lengths and different cross-sections;

(20) d) regions 4 and 5 with different cross-sections and different lengths.

(21) The stretch modulus (which mainly depends on the cross-section and length, with identical conditions of the process for producing the composite material) of the region 3 is higher than the stretch modulus of the regions 4 and 5.

(22) If the stretch modulus of the regions 4 and 5 is identical then there will be two portions with different flexibilities along the rod-like body 2.

(23) If on the other hand the stretch modulus of the regions 4 and 5 is different, then there will be three portions with different flexibilities along the rod-like body 2.

(24) The body 2 which FIG. 1 illustrates for the purposes of example as a temple of an eyeglass frame can also constitute the upper bar 10 of the frame of the eyeglass frame (as illustrated in FIG. 3), which can have in this case too at least one first region 3 and at least two second regions 4 and 5 of the same length, or it can have one region 3 and two regions 4 and 5 of mutually different lengths.

(25) The component of a frame for eyeglasses provided in this manner makes it possible to define, along the extension of the rod-like body 2, mutually different cross-sections as shapes, so as to be able to have, along the length of the body 2, different shapes that contribute to creating a three-dimensional effect of the temple or of the upper bar of the front of the eyeglass frame.

(26) An adequate flexibility of the body 2 is ensured by the presence of regions with thicknesses and heights which are different from those of the remaining regions, accompanied by an excellent mechanical strength in that the region or the regions 3 of greater thickness and height (and thus rigidity) than those of the remaining regions of the body 2 make it possible to provide the mechanical rigidity required by the component of a frame for eyeglasses 1.

(27) The region 3 of the rod-like body 2 makes it possible to obtain, for the rod-like body 2, a ratio of strength to deformation that allows the existence of one or more maximum points. In the event of the presence of more regions 3 the ratio of strength to deformation is always of the type mentioned above, but with a different period. In practice it has been found that the component of a frame for eyeglasses according to the present disclosure fully achieves the set aim and objects, in that it makes it possible to offer a differentiated flexibility with respect to conventional components, accompanied by an excellent mechanical strength, combined with an attractive appearance due to the three-dimensional effect created by regions of the body 2 with differentiated cross-section.

(28) The component of a frame for eyeglasses, thus conceived, is susceptible of numerous modifications and variations.

(29) Moreover, all the details may be substituted by other, technically equivalent elements.

(30) In practice the materials employed, and the contingent dimensions and shapes, may be any according to requirements and to the state of the art.
