Nosepiece for eyeglass frames

Abstract

Nosepiece for eyeglass frames, which comprises a plate (4), an appendage (5), at the rear part and projecting from the plate (4) and mechanical retention means (7) adapted to fix the appendage (5) to the frame (20) of eyeglasses (100), which comprise a cup (8) fixed to the frame (20) according to a longitudinal extension axis (Z), provided with at least two opposite lateral walls (9), joined together by at least one connection wall (10) and with two aligned first through holes (13) extended along a second transverse axis (K), substantially orthogonal to the first longitudinal axis (Z). The appendage (5) comprises a convex portion (5A) delimited by two faces (50) with a second through hole (14) aligned with the first through holes (13) along the second transverse axis (K). The appendage (5) is at least partially housed within the cup (8) with the faces (50) facing the lateral walls (9) of the cup (8) and is susceptible of rotating with respect to the cup (8) around the second transverse axis (K) with the surface of its convex portion (5A) in contact and in sliding-with-friction relation with the internal surface of the at least one connection wall (10), in order to maintain the plate (4) in the angular position reached around the second transverse axis (K). A screw (70) is provided, engaged in the first through holes (13) of the cup (8), having the shank (70") placed to traverse the second through hole (14) of the appendage (5), the latter being susceptible of rotating with respect to the cup (8) around the first longitudinal axis (Z) with the surface of its convex portion (5A) in contact and in sliding-with-friction relation with the internal surface of the at least one connection wall (10), in order to maintain the plate (4) in the angular position reached around the first longitudinal axis (Z).

Description

technical field [0001] According to the preamble of the main independent patent claim, the present invention relates to a nose pad for spectacle frames. [0002] The nose pads are beneficial to be applied in the production of spectacle frames, especially metal frames, and a pair of pre-set nose pads can determine an ergonomically correct position for the support of the spectacle frames on the nose. [0003] Therefore, the nose pad according to the present invention relates to the industry of eyewear producing eyeglasses and their accessories and eyeglass components. Background technique [0004] In the eyewear industry, traditional nose pads are regarded as a part of the frame, which is used to support the glasses on the user's nose to improve comfort. [0005] According to one of the most common implementation forms on the market, each nose pad includes a blade, which has a front for supporting on the user's nose and a rear, and a stake protrudes from the rear of the blade...

Problems solved by technology

[0018] Another drawback of nose pads using known ball / socket type locking tools is that in most cases there is a lack of means to limit the rotation of the blades, or even if there is a means to limit the rotation of the blades (such as described in US4681411). case) is still not suitable and has low durability
