Abstract
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.
