Abstract: An eyewear utilizing a screw-less hinge to connect the temple to the frame. The frames terminate laterally at an open, curved rung configured to receive a cylinder. This cylinder is fixed to the temple. Due to the configuration of the curved rung, the cylinder can he inserted into the curved rung in a rotatable or pivotable fashion. The cylinder receiving the curved rung holds the frame together and keeps eye wires from opening, thus keeping lenses from falling out of the eyewear. A wedge tool can be used to displace the curved rung from the cylinder to easily remove the temple from the frame.

Abstract: The most practical production of this innovation is shown in pictures 11 and 12. The connective element (1) is pushed into the housing (54) executed in the temple (5), and then in the housing (111) at the open end of the connective element (1) we mount the spring (2) that is not tensioned, and then the screw (15) that goes through the spring (2). Both the screw (15) and the spring (2) are sized in such a way that they can move axially in the housing (111) of the connective element (1). The screw (15) goes through the narrowed part (12) of the housing (111), and at the same time the spring cannot go through the narrowed part (12). The screw (15) is screwed into the temple (5) with screwdriver passing through the housing (111) and it compresses the spring (2) by its head until it reaches closing delimiter. The connective element (1) mounted into the temple (5) in mis way, is then placed in the housing (4) of the frontal ending (6).
