Abstract

A molded unit including several members of eyeglasses uses a combination of hard plastic and shape-memory plastic to avoid sliding and protruding of the members. <??>The unit frame comprises a metal core embedded in a substrate made of hard plastic of which heat deformation temperature is higher than 50 degrees centigrade, and shape-memory plastic that is disposed outside the substrate and has a glass-transition temperature of between 20 degrees centigrade and 40 degrees centigrade. The shape-memory plastic is positioned where a human body contacts.

Description

[0001] This application claims the benefit of Japanese Patent Application No. 2001-225411, which is hereby incorporated by reference. technical field [0002] The present invention relates to eyeglasses, and in particular to end pieces for eyeglass temples, eyeglass temples with end pieces, and units for eyeglass frames. Background technique [0003] The spectacle frame has a front portion for supporting or supported by the lens (ie, the front portion supported by the lens in rimless glasses), a pair of temples, and a pair of hinges for connecting the front portion to the pair of temples. [0004] The spectacle frame also has a pair of nose pads positioned between the left and right lenses, and a pair of end pieces mounted on a pair of temples. The nose pads contact the user's nose, and the pair of end pieces contact the user's ears, so that the glasses are supported on the user's head. [0005] If the temples of the glasses are entirely made of metal, the use of such glass...
