US 2023/0266608 A1 · HINGE FOR EYEWEAR

Abstract

A hinge mechanism for eyeglasses which enables replacement of the temples from a lens frame without the need for any pins or tools, and without small or weak parts. The hinge mechanism between each of the temples and the lens frame includes a male component which fits into a female component and may be adjusted in two ways. The torque required to assemble the temples to the lens frame can be adjusted, as well as the torque required to transition the temples from the folded to the unfolded position. Both adjustments may be affected by the choice of materials of one or both of the hinge components. The male component may be on the end of each of the temples and sized to fit within the female component on either end of the lens frame. Rotating the temples 90° snaps them into place, and they can easily be removed by the reverse operation.
