US Patent 11397338 Eyewear accessory mount

A mount that reversibly couples with an eyeglass-frame temple to enable adjustment of the balance of eyeglasses is presented. The mount includes a rigid outer shell whose interior area is filled with a resilient material. The rigid shell provides strength, while the deformability of the resilient material enables the mount to securely conform to the shape of any of a wide range of temple designs virtually anywhere along its length. Additional counterweights and/or other accessories can be attached to the mount, as desired. The shell includes a clamp that comprises a u-shaped frame and a hasp that is joined with the frame at a rotary joint. The hasp is rotated about the rotary joint to enable its attachment to, and release from, the frame. The free end of the hasp connects with the frame via a clasp that is configured to mitigate the inadvertent decoupling of the hasp and frame.
