Attachable eye-protective frame for glasses

Abstract

A detachable shelter frame is adapted for mounting on a primary spectacle frame by means of at least two resilient mounting devices. Each of the resilient mounting devices comprises a resilient arm extending rearwardly from the respective auxiliary lens of the shelter frame to ride on the primary spectacle frame, and an engaging member which is connected to the resilient arm and extended to press against a rear side of the primary spectacle frame, wherein the two resilient arms substantially pull the two engaging members towards the primary spectacle frame so as to apply an urging pressure against the primary spectacle frame for holding the frame body of the primary spectacle frame between the shelter frame and the engaging members, so as to securely mounting the shelter frame in front of the primary spectacle frame.

Description

technical field [0001] The present invention relates to spectacle frames, and more particularly to detachable eyewear frames, such as sunglasses, having auxiliary lenses which can be attached to original spectacle frames by means of an elastic coupling. Background technique [0002] Goggle frames are widely used today, and a conventional goggle frame such as clip-on sunglasses includes a number of detents for removably attaching to near-sighted or far-sighted glasses so that the wearer does not need to wear or purchase another pair of near-sighted or far-sighted glasses. Farsighted sunglasses, but during the installation process, the metal claws may scratch the lenses of the original frame, and the wearer needs to use both hands to align the traditional clip-on sunglasses with the original glasses to the original frame.

[0002] Goggle frames are widely used today, and a conventional goggle frame such as clip-on sunglasses includes a number of detents for removably attaching to near-sighted or far-sighted glasses so that the wearer does not need to wear or purchase another pair of near-sighted or far-sighted glasses. Farsighted sunglasses, but during the installation process, the metal claws may scratch the lenses of the original frame, and the wearer needs to use both hands to align the traditional clip-on sunglasses with the original glasses to the original frame. Right position up, it is cumbersome and dangerous for the eyeglass wearer to use his or her hands to put on such snap-on sunglasses over regular eyeglasses while he or she is driving

[0003] In order to solve the above-mentioned problem of snap-on sunglasses, magnetic attachments have recently been introduced in the eyewear industry. A pair of main magnetic assemblies are respectively attached to the two upper side extensions of the original frame, such as the goggle frame for sunglasses. A pair of arms, so as to be placed on the top of the upper side extension, so as to prevent the goggle frame from moving downward relative to the original frame, while a pair of auxiliary magnetic assemblies respectively connected to the two arms are used to communicate with the main magnetic assembly of the original frame. combination, so that the goggle frame can be stably mounted on the original frame, however, the user must align the two pairs of magnetic assemblies, if the auxiliary magnetic assembly of the sunglasses is not aligned with the main magnetic assembly of the original frame, the sun Glasses are easy to fall off from original frame

[0004] Therefore, the main disadvantage of eyeglasses with magnetic attachments is that the original frame needs to be changed in its original structural design in order to attach a magnetic component to it, therefore, the wearer of the glasses must buy a pair of eyeglass frames including the original frame and the sunglasses , in doing so, it is much more expensive than sunglasses where the wearer only has to buy a card to snap on, and in addition, a pair of main magnetic components are always located in front of the user's eyes
