发明名称 SWELLING POLYMERS PADDED SPECTACLE FRAMES
摘要 The invention proposes a novel method for providing a covering pad member of silicone rubber to a frame of spectacles on the portions coming into contact with the human body of the wearer of the spectacles, such as the side pieces and the nose pads. According to the inventive method, a shaped member of the silicone rubber having dimensions somewhat smaller than the portion to be covered therewith is first swelled with an orgnosilicon compound having volatility, inserted to the portion, e.g. sidepiece, and then dried by evaporation of the organosilicon compound as the swelling agent whereby the member shrinks to fit the portion of the frame tightly. Organosilicon compounds, e.g. hexamethyldisiloxane, are recommended owing to the physiological inertness to human body as well as owing to the absence of aggressiveness to the plastic part used in the frames of spectacles causing no damage to the beautiful appearance of the frame even in an inadvertent contact.
