AI Technical Summary

Problems solved by technology

This results in glasses that are relatively heavy, which necessitates a reduction in thickness to limit this defect
Therefore, the degree of freedom in the shape of the stent is limited

Embodiment Construction

[0030] figure 1 The spectacles 1 shown as a whole in , comprising a corrective appearance, the two lenses 2, 3 are connected to each other by a nasal bridge 4, and at the outer ends of the two lenses are two brackets 5.

[0031] This embodiment relates to so-called "drilled" spectacles, ie rimless spectacles.

[0032] The support 5 is not hinged to the hingeless lenses 2, 3, but is elastically deformable so as to be lightly fastened on the user's head in the unfolded state and for example stored in the folded state.

[0033] According to the invention, the support for such spectacles is exclusively made of a composite material consisting of at least one layer of reinforcing fabric 6 and a coating 7 or matrix made of thermoplastic or thermosetting material (see Figure 4 ).

[0034] Tests have shown that when fabricated in this way, the stent is more flexible even without a metal core.

[0035] Figure 4 with 5 Different layers are shown juxtaposed to each other, each laye...

Abstract

The invention relates to an elastically deformable, hingeless spectacle arm that is made exclusively of composite materials, and which comprises at least one layer of a reinforcing cloth (6) and a coating (7) or matrix made of a thermoplastic or heat-curable material.

Description

technical field [0001] The invention relates to a method for realizing a hingeless elastically deformable spectacle holder. Background technique [0002] A twist-free spectacle holder has been proposed to reduce the number of accessories, simplify the assembly procedure and limit the source of user discomfort, ie, the holder unscrewing or free running. [0003] In order to avoid these problems, it is known to realize hingeless spectacle holders with metal alloy cores, for example based on nickel-titanium-copper or also based on shape-memory alloys of titanium-aluminum-vanadium, wherein the metal core obtained is substantially cylindrical . [0004] These materials are beneficial because they have excellent flexibility and excellent responsiveness, and can return to the original shape flexibility after the glasses are worn or folded for a long time. Such braces are therefore usually coated with a more or less flexible plastic material to improve comfort, at least in the she...
