Eyeglass Frame Coupling Block for Lens Stability

The patent extracts the fastening function from visible external screws and relocates it to internal structural features. The upper and lower frame sections incorporate integrated engagement structures (such as recesses, protrusions, or interference-fit features) that mechanically interlock to secure lenses, eliminating the need for externally visible screws while maintaining securing reliability.

The patent merges the frame structure with the fastening mechanism by integrating the securing features directly into the upper and lower frame sections. The engagement structures are combined with the frame geometry itself, creating a unified assembly that provides both structural support and lens securing functionality without separate fastening components.

The patent incorporates preliminary anti-action by designing engagement structures that prevent disengagement under external forces. The upper and lower frame sections include features such as overhangs, interference-fit geometries, or mechanical interlocks that create resistance to separation forces, ensuring that even when subjected to impact or external stress, the frames cannot completely disengage and lenses are retained.

The patent employs curved or rounded engagement features rather than sharp linear interfaces. The engagement structures incorporate rounded corners, curved surfaces, or spherical elements that provide mechanical advantage in preventing complete separation, as the curved geometries create friction and mechanical interference that resist disengagement under external forces while still allowing controlled assembly.

The patent employs composite structural features combining magnetic elements with mechanical interlocking structures. The upper and lower frame sections integrate magnetic members for closure attraction with rigid mechanical engagement features (such as interlocking geometries, recesses, or protrusions) that provide structural strength. This composite approach allows the magnetic force to secure normal closure while the mechanical structures prevent expansion and lens loss under larger external forces.

The patent segments the closure mechanism into distinct functional components: magnetic attraction elements for normal closure and mechanical interlocking elements for force resistance. This segmentation allows each component to perform its specialized function optimally—the magnetic members provide easy closure and holding force, while the separate mechanical engagement structures provide rigid resistance to expansion and external forces that would otherwise overcome the magnetic attraction alone.
