Abstract:

An auxiliary earpiece is disclosed that is positively, adjustably, and removably attachable to an eyeglass bow with the aid of an insert. The earpiece includes an ear-engaging portion and a bow-receiving portion through which the bow is passed. The insert includes a wedge-like section that is positioned within the bow-receiving portion of the earpiece adjacent one side of the bow. By appropriately positioning the insert with respect to the bow-receiving portion of the earpiece, an interference fit is produced between the bow, the insert, and the earpiece to provide the desired attachment. The resultant side-to-side clamping works well with a wide variety of eyeglass frames making the earpiece relatively interchangeable among eyeglasses.
