Nose pad for eyeglasses
摘要:
This invention relates to a nose pad assembly for use in eyeglasses. The nose pad assembly comprises a plastic nose pad and a mounting arm to be secured to the frame of the eyeglasses. Detent means are provided for resiliently interlocking a depending free end portion of the mounting arm with a boss on the rear of the nose pad so as to permit a limited pivotal movement of the nose pad about said free end portion. In one embodiment of the invention the boss of the nose pad is formed with a socket hole, which is open at its top end and closed at its bottom, and the detent means consist of a plurality of vertically spaced apart ball sockets formed in the elastic boundary surface of said socket hole and of a ball, which is formed at the extreme end of the free end portion of said mounting arm and interfits with said ball sockets. Said ball and each of said ball sockets is formed with flats, which in the assembly are radially spaced apart and cooperate with each other to limit the pivotal movement of said nose pad about said free end portion.
