Description

Hinge structure that can be reset in multiple directions

The present invention relates to a hinge structure that can be reset in multiple directions, in particular to a hinge installed between the frame of the glasses and the feet of the glasses.

The operation that the temples of the spectacle frame can be expanded or folded relative to the frame is achieved by the "hinge". The traditional hinge can only provide the operation of opening or folding the temples relative to the frame, or can be further allowed The angle allows the spectacle frame to expand horizontally. Therefore, the spectacle frame is often deformed or broken due to the impact of external force.

Please refer to China Patent No. CN107688247. The hinged relationship between the front hinge and the slingshot box is horizontal, that is, the temples can swing horizontally, including excessive opening to the outside of the temples, or move the temples toward the frame Folded inside. Although the temples in this case are equipped with springs to allow the temples to expand horizontally to the outside, they have no elastic tolerance effect for other force directions. Therefore, when the glasses are impacted by external forces, they will deform or break Situation.

Please refer to Taiwan Patent No. TWI274930B again. The technology of this case ensures that under the action of external force, or under the action of elastic force after the external force disappears, the axis only moves in the direction restricted by the square hole, that is, the axial movement, thus restricting the axis of the hinge. The indefinite movement and relative rotation of the center relative to the radial direction of the frame (radial at any angle of 360 degrees), so when the glasses are impacted by an external force that is different from the pivoting direction (horizontal direction) of the axis and the temples At this time, it may still cause deformation or breakage of the frame and the mirror feet.

In order to solve the above-mentioned lack of hinges, the present invention provides a hinge structure that can be reset in multiple directions.

The main purpose of the hinge structure of the present invention that can be reset in multiple directions is to make the hinge of the present invention not only have the existing inward horizontal hinge direction, but also have an angle that allows up, down, and outward expansion in multiple directions to avoid the hinge It is damaged by external impact.
