The front end portion 68 can be coordinated with the joint portion 24 to conform to the particular needs of the frame 14 to attach the bridge 18 thereto.

The nose bridge 18 of the present invention can be made by a molding process. For example, the base structure 20 can be formed by a first molding material in a first molding process, wherein the first molding material is relatively rigid after crosslinking. The molded base structure 20 can be integrated with its aforementioned components and components to form a unitary unitary assembly. Preferably, the molding process of the base structure 20 can be combined with the molding process for manufacturing the frame of the glasses, so that the base structure 20 can be integrally formed (permanently joined) with the frame 14. However, the base structure 20 can also be molded separately from the frame 14 and can be attached to the frame 14 in a separable manner by known or unknown bonding means. In a second molding process, a combination of the molded base structure 20 is further molded to form a soothing sheet 22 incorporating the aforementioned components and components, and the molding process is utilized. The two-die casting material is carried out, wherein the second molding material after crosslinking is softer and more flexible than the molding material of the base structure 20. Since the molding is performed on the molded base structure 20, the relief sheet 22 is molded over the base structure 20 and an appropriate attachment is achieved. For example, a nose pad and a curved pad are attached to corresponding faces of the base structure 20. The second molding material can be filled into the first recess 38 and the second recess 40 in the nose piece body 26 in this molding process to form the desired filler members 56, 58. Preferably, when the molding process of the base structure 20 is combined with the molding of the frame 14, the molding process of the relief sheet 22 can be introduced into the integrated frame 14 and the base structure 20. Carried on.

The relatively rigid base structure 20 provides a contoured profile and assembly of the nose bridge 18 of the eyeglasses. The combination of the grooves on the nose frame 26 and the connection method of the nose frame 26 to the joint portion 24 are advantageous for providing a bridge 18 which is comfortable and versatile, and maintains sufficient rigidity when self-adjusting is performed. Provide a robust configuration. For example, the lateral buckling as indicated by arrow 70 and the upper buckling indicated by arrow 72 (see Figure 2) allow the bridge 18 to be self-adjusting according to the contour of the nose when supported on the nose of the respective user. The soft and flexible material of the soothing sheet prevents the rigid body portions of the nose bridge 18 from directly contacting the user's nose, thereby providing comfort.

After the relief sheet 22, the spacer 64 is positioned below and isolated from the bridge portion 44 of the base structure 20, which will facilitate enhanced upper buckling (as indicated by arrow 72). In addition, the rear gasket 64 is combined with the front end portion 68 of the soft and flexible cushioning sheet 22 to facilitate the occurrence of anterior impact when foreign objects strike the nose bridge 18. The relatively soft and flexible filler members 56, 58 are received within the first recess 38 and the second recess 40 to enhance the aesthetically pleasing configuration of the recess without compromising the multiple modulation of the bridge 18.
