Description

Technical FieldThe invention relates to the technical field of eyeglasses and more particularly to a spring washer and an elastic hinge structure having interchangeable and multifunctional properties.Prior ArtThe wearing comfort and durability of eyeglasses have always been the focus. The manner of connection between conventional eyeglass frames and brackets, namely the hinge structure, normally assumes a rigid design. After the temple is opened, the angle between the temple and the eyeglass frame is maintained substantially in a vertical state. The eye glass can not rotate farther outward relative to the eye glass frame; although this hinge structure is simple and immediate when the user wear the eye glass with a large head circumference, the clamping is too strong, which reduces wearing comfort because the eye glass can not rotate farther outward relative to the eye glass frame. When the user continues to wear the eyeglasses, the two temples are forced to expand outward; this unnatural state of expansion can easily result in damage to the temples and the hinge part connected to the temples, which affects the life of the eyeglasses.Therefore, it is an urgent problem for technical personnel in the field to provide a simple structure that can be applied to persons having different head sizes while improving wearing comfort and durability and can be applied to eyeglasses of various types and materials.
