Description

Elastic automatic adjusting structure of glasses leg and glasses using same

Technical Field

The utility model relates to the technical field of glasses, in particular to a structure capable of automatically adjusting the elastic size of a glasses leg and a glasses product applying the structure.

Background

Glasses are well known as articles for improving vision, protecting eyes, or for decorative purposes. Glasses are typically composed of a lens and a frame. The glasses frame comprises a front frame, a middle beam, a pile head and glasses legs. The lens is installed on the front frame, the middle beam is located in the middle of the front frame, the pile heads are installed on the left side and the right side of the front frame, and the lens feet are hinged to the pile heads in a deployable or foldable mode. When the glasses are worn, the middle beam is arranged on the nose bridge, and the glasses foot rest is arranged on the ears.

The common glasses have the advantages that the whole structure is not provided with encircling designs, the glasses legs are not specially increased in elasticity, and the frame surface of the glasses frame is narrow. If the face shape of the user is large, the left and right sides of the head can be squeezed when the user wears the glasses, and the user can generate indentation due to the glasses legs after wearing the glasses, so that the user can easily feel oppressed to the head, and discomfort is caused. In addition, as the glasses legs are propped up by the head, the glasses legs without elasticity can drive the front frame to bend and deform reversely at the middle beam, so that the change of the lens test and matching data (pupil distance) is caused, and the health of eyes of a user is affected.

In view of this, the present inventors have developed a novel structure suitable for a temple through repeated research, design, experiment, modification and test by virtue of the level of expertise and accumulated experience of long-term research, design, and manufacture, and familiarity with structural properties of products.
