Claims (4)

1. An eyeglass frame characterized by comprising, in the frame structure of the eyeglass, a lens frame that fixes the lens and a hinge device that combines the lens frame and the temple, wherein the hinge device is made of an elastic material and designed so that the frame can be flexibly adjusted to fit the user's face, and the frame and the temple are stably combined through a click-type coupling device mounted on the end of the temple.
2. An eyeglass frame according to claim 1, wherein the elastic material comprises a polyamide and a metal material to enhance durability, and a protective film is formed on the outer side of the joint portion to continuously maintain the hinge joint state of the temple so that the frame does not deform even after prolonged use.
3. An eyeglass frame according to claim 1, wherein the click-type coupling device includes fixing protrusions corresponding to each other at the hinge end of the temple and the coupling portion of the lens frame, and is configured such that a stable coupling sound is generated between the frame and the temple when the temple is folded or unfolded at a specific angle, allowing the user to intuitively recognize the coupling state.
4. An eyeglass frame according to claim 1, wherein the temple includes an up-and-down rotation limiting device when combined with the frame, thereby allowing the temple to rotate only to a specific angle so as to be in close contact with the user's face and protecting the durability of the frame from excessive movement.

Description

Elastic Material-Based Click-Type Eyeglass Frame Assembly Structure Elastic Material-Based Click-Type Eyeglass Frame Assembly Structure The present invention relates to an eyeglass frame and lens coupling structure that enhances durability, functionality, design applications, and ease of assembly by using an elastic material and a click-type coupling method. The structure of eyeglass frames must consider wearer comfort and durability, and requires a special design, particularly to prevent deformation from prolonged use and to securely fasten the lenses. Currently, most eyeglasses are made of materials such as metal and plastic and feature a structure that allows for easy attachment and detachment of lenses. However, in existing technology, the connection between the lens and the frame may show weaknesses in terms of long-term durability, and frame deformation or lens loosening may occur due to repeated use. Additionally, design limitations may arise when adjusting the eyeglass frame to fit the user's various face sizes and shapes. To solve these problems, the present invention provides an eyeglass frame and lens assembly structure that possesses both durability and ease of assembly. FIG. 1 shows a side view, a top view, and a cross-sectional view relating to the eyeglass frame and lens combination structure of the present invention. The eyeglass frame of the present invention is composed of a combined structure of metal and plastic materials. The metal frame is responsible for durability, while the plastic part provides a lightweight wearing experience. The lens is mounted on the front part of the frame, and a click-type coupling method is adopted for fixing the lens. This allows for easy lens replacement and maintains a secure connection. The connection points of the lens minimize external protrusions such as screws to maintain aesthetics while increasing connection strength. The nose pads are designed with an adjustable structure, allowing users to adjust their position and angle to fit their individual face shape. The temples are the parts of the glasses that rest on the ears, and they feature a function to adjust the temple length. This allows users to adjust the temple length to fit their face size. The eyeglass frame design adopts a polygonal lens structure to naturally suit various face shapes. The temples contain reinforced metal material inside, allowing them to maintain their original state without deformation even after prolonged use. The frame of the present invention allows for various design applications, and the colors and materials of the temples and frame can be applied differently to suit the user's preferences. The joint between the temples and the frame is manufactured with a specially reinforced structure to disperse the stress generated during the wearing and removal of the glasses, thereby preventing frame deformation. The joint between the lens and the frame is waterproofed, preventing a decrease in bonding strength caused by moisture or water penetration while wearing the glasses. The present invention provides both stability and comfort when wearing glasses through a combined structure of a frame and a lens, and is designed so that the lens does not easily detach even under external impact. Both the frame and temples of the glasses are designed as replaceable modular parts, allowing for various design changes to suit the user's preferences.
