Bistable hinge element for eyeglasses frame
A recently granted patent (Publication Number: US11921358B2) discloses a unique bistable hinge element designed for eyeglasses frames. The hinge element comprises a temple cage and a front cage, each with specific features such as U-shaped openings, upper lips, and complementary guiding segments. These components work together with a solid, elastically deformable body to achieve a bistable effect, keeping the temple in either an open or closed position without freely oscillating between the two. The design allows for a specific displacement range between open and folded positions, as well as precise dimensions and shapes for optimal functionality.
Furthermore, the patent includes claims related to the specific dimensions and shapes of the components, such as the height and width of the solid body, the shape of the bulges at each end, and the revolution path of side bumps. Additionally, the patent extends to an eyeglasses frame incorporating this unique hinge element, with the solid body featuring a longitudinal canal for electrical conductors to ensure electrical connection between the temple cage and front cage. Overall, the patented bistable hinge element offers a novel solution for eyeglasses frames, combining innovative design elements to achieve a stable and functional hinge mechanism for improved user experience and durability.
