Abstract

PROBLEM TO BE SOLVED: To make it possible to form slimmer ear bends of spectacles to be mounted at the temples of a spectacle frame, to reduce its cost and to assure its strength. SOLUTION: The ear bends 1 are composed of resin materials 11 fixed to the circumferences of arbors 2 and resin type coating materials 12 formed by dip coating around these materials. A urethane system, epoxy based material, etc., are used as the coating materials 12. The resin materials 11 are constituted by incorporating about 10.5% powder of tungsten (W) as a high sp. gr. material into a polystyrene based elastomer resin. The tungsten is as heavy in sp. gr. as 19.3 and therefore, the weight over the entire part of the ear bends 1 is increased in spite of a small content. The degradation in the bending strength of the resin materials 11 is averted as far as possible.
