Description

  The present invention relates to flip-up / folding glasses that can be flipped up by rotating a front portion around a bridge, and can be folded and stored compactly.

  In recent years, front-type glasses and flip-up type glasses are frequently used. However, the front-type glasses are configured such that another front frame is detachably attached to the front of the front portion. On the other hand, the flip-up glasses have a structure in which the flip-up frame can be lifted upward as needed without attaching or removing the flip-up frame.

  The front-type glasses and the flip-up type glasses have advantages and disadvantages, and each can be selected according to preference. Although the present invention is directed to flip-up glasses, there are various mechanisms for flipping up the flip-up frame (front portion). However, the basic structure is the same, and it can be rotated upward via a shaft provided on the front side, and is held at a predetermined angle and does not fall.

  The “detachable flip-up spectacle frame” according to Japanese Patent Application Laid-Open No. 2004-334067 is a detachable front-type flip-up multifunctional spectacle frame that can be easily operated by the magnetic force of a magnet. In other words, it is important that the front frame is attached to the bridge, so that both functions can be integrated into the bridge. A magnet is fitted at a relative position in a state where the frames are overlapped, and the magnetic force of the magnet is used to hold and stabilize the front frame bridge and the front frame bridge.

The “bounce-up type spectacle frame” according to Utility Model Registration No. 3121730 is equipped with a mechanism part for the movable frame part to jump up to the front side, and is installed on the back side or on the same axis so as not to impair the overall design and is elastic. A plurality of force generating portions are dispersed in both the spectacle main body portion and the movable frame portion to obtain a boosting action, thereby reducing the size of the spectacles beyond the limit of downsizing of conventional elastic force generation.
Therefore, the rim attached to the movable frame can be rotated around the flip-up shaft, the flip-up shaft, the rim can be turned from the spectacle main frame portion to the front, and one of the embodiments of the elastic body. A spring which is a form, and a thick contact action is generated in the meshing portion by the action of the spring, so that any angle can be fixed at any time.

As described above, the conventional flip-up glasses have various flip-up mechanisms, but the structure is complicated and difficult to assemble. Therefore, the production cost increases, resulting in expensive glasses.
