Description

Folding structure of glasses frame bridge

The present invention is a foldable structure of a spectacle frame bridge, and when described in more detail, the bridge connecting the frames on the front of the spectacles to which the spectacle lenses of both sides are coupled is easily folded and unfolded by elasticity. It's about structure.

In general, glasses (glasses) consisting of a lens (glasses) and a glass frame (glasses frame) refer to lenses worn to correct vision. In this case, the glass frame is worn by a hinge on the front (front of glasses) and the end pieces (end piece) of both sides of the front that connect and couple the lenses on both sides. A temple tip (tip of a leg) is configured to be hung on the ear on the curved temple end (temple: glasses leg) and the curved temple end, and the front is the center of the rims (rim: lens rim) on both sides to which the lenses are coupled. It is configured to be connected by a bridge from It is made in various forms, such as the nose pad being integrally formed on the rim without an arm, and as such, in the case of conventional glasses, both rims to which a pair of lenses are coupled are connected by a bridge, so even if the temple is folded around the hinge, the glasses The left and right sides of the front side of the front desk take up a lot of volume, so it was quite inconvenient to store and transport it. Since there are disadvantages such as separation, many technologies have been developed to minimize the volume when storing and transporting the glasses by folding the front of the glasses.

As a technology in which the front of the conventional glasses has a foldable structure, as disclosed in Korean Utility Model Publication No. 4634, 2015 (published on December 30, 2015), the temples on both sides of the multi-stage are folded toward the hinge, and the lens Although a structure has been developed in which the combined bilateral spectacle frames are rotated upwardly around the nose support (=bridge), even if the rim of the spectacle frame is rotated upwardly in the bridge, both lenses exist on the same plane, so the space of the bridge Only the degree disappears, the volume occupied by the two lenses remains the same, and there is a problem that the multi-stage temples can increase in volume due to the folded space.

Therefore, the structure in which the lenses on both sides are folded to overlap can minimize the volume of the glasses. As published in Model No. 270188 (notice dated March 28, 2002), Utility Model Registration No. 296581 (notice dated November 29, 2002), connecting both lens frames (Registered Utility Model No. 198280) (Registered Utility Model No. 270188) and the connector (Registered Utility Model No. 296581) were connected with hinges on both sides to overlap the lenses on both sides. If the rim with lenses on both sides is overlapped by a simple pin-coupled hinge, the hinge part becomes loose when used for a long time, so the rim where the lenses on both sides are combined in the bridge is arbitrarily folded or unfolded. When unfolded or folded, both rims are shaken at the bridge, which leads to more frequent damage and a sharp drop in overall durability of the glasses.
