Problems solved by technology

[0022] Comparing all these solutions, it is clear that they are basically complex mounts using many parts and small elements that, in addition to making the structure heavy, make the assembly steps unreasonable, resulting in considerable production costs
Together these solutions make the assembly and control of many coded items in a store a complex problem

Embodiment Construction

[0053] In one of the preferred applications, with reference to the accompanying drawings, there is a light-weight spectacle structure given by a front lens holder 1 connected to an arc 2 and suspended centrally.

[0054] In a first embodiment, the front lens holder 1 consists of a shaped, continuous, bendable, metallic profile in the form of a closed loop adapted to surround each lens in the spectacles. Almost the entire circumference of the lens is rim fastened. The shape given to the lens holder 1 is such that two left and right rings 11 are formed, which are connected together by a middle part 10 of a connecting bridge formed between them. Therefore, in this case, each of the left and right lenses is fixed by the same lens holder 1 . Furthermore, in the middle part 10 of the lens holder 1 , corresponding to the connecting bridge between the two rings of said front lens holder, the profiles are brought together so as to form a gap between the lenses thus held. The correct ...

Abstract

The spectacles assembly is equipped with the bow-shaped frame and the support clip for the interchangeable frontal lens holder. If necessary, it is equipped with a bow-shaped structural body and an arm for supporting the frontal lens holder, the frontal lens holder which surrounds at least a part of the outer edge of the lens, and a device with a flexible movement used to connect the frontal lens holder to the bow-shaped structural body. In the flexible device formed corresponding to a bridge connecting two bow-shaped parts making up the bow-shaped structural body to each other, the frontal lens holder has a connection bridge for supporting the peripheral parts of both lenses, and the bridge is locked and hung by the clip formed monolithically on the bow-shaped structural body.

Description

technical field [0001] The object of the present invention is an eyeglass assembly having a curved frame and support clamps for an interchangeable front lens holder. Background technique [0002] This proposal can be used in particular, but not exclusively, in the production and trade sectors involving lightweight multipurpose eyewear. [0003] Spectacle frames are known which essentially consist of a frame for fixing the lenses, i.e. a front part formed by two spectacle rings connected together by an intermediate bridge, the nose pads, the intermediate bridge And nose pads are sometimes integral with two rings and by two support arms. [0004] There are various solutions on the market. Among the most prominent solutions there is, for example, EP546589 (Lindberg) aimed at support means for lenses in spectacles, especially of the wire frame type. Variations of the main solution are also described, especially with regard to the support structure for the lenses, in this case...
