Patent attributes
A spring hinge for an eyewear includes a front frame having an attachment portion and a first articulation hinge element, a temple connected to the front frame and having a hollow housing at an end portion, a cover member with a front bump for covering an outside opening of the temple, and a U-shaped slide member with a second articulation hinge element. The U-shaped slide member is housed in the hollow housing to be slidable along a longitudinal direction of the temple. A compression coil spring is provided between the front bump and the U-shaped member in a compressed state. The temple and the attached portion are rotationally connected at the first and second articulation hinge elements. When the temple is pushed outwardly, the temple is opened from a position perpendicular to the front frame, while the compression coil spring is being compressed.
