摘要:
The present invention relates to a thermoplastic laminate for an eyewear, a decorative part comprising the thermoplastic laminate and a preparation process therefore. In particular, during the preparation of the laminate, a high frequency welding machine is used for bonding thermoplastic layers. The present invention uses a high frequency welding machine for the instant welding of the thermoplastic layers. Good bonding strength exists between different layers. Further, the patterns of the core layer are intact, and have high-definition images. The patterns are located in the core layer, not affected by external environmental factors, and not easily abraded. Further, multiple surfaces of the part for an eyewear have patterns, increasing the beautiful appearance of the part for an eyewear, and meeting the requirements of customers to the largest extent.

Provided herein is a flexible hinge comprising a tension spring (1), a sliding element (2), a sliding element guide (3), a spring tensioner (4), a stop (5) for stopping the longitudinal movement of the sliding element (2), a fastener (6), and a bearing shield (7). The flexible hinge disclosed herein can be installed in a pair of eyeglasses comprising a pair of temples and a frame front so as to connect the temples to the frame front. The flexible hinge can be fixed to the temple with the stop (5) at one end and to the frame front with the fastener (6) at another end. The fastener (6) is used to engage sliding element (2) with the bearing shield (7). The sliding element guide (3) enables longitudinal movement of the sliding element (2) along the x-axis and prevents its movement along other axes.
