ABSTRACT:
This invention discloses a nose piece assembly for adjustably mounting a nose piece to an eyeglasses frame having a pair of correction lenses connected to each other by a rigid cross piece. In the preferred embodiment, the nose piece assembly comprises a nose piece for engaging the nose of the wearer, a mounting member for adjustably connecting the nose piece to the cross piece of the eyeglasses, and a guide way for maintaining the alignment between the nose piece and the eyeglasses. The outer dimensions of the nose piece are standardized while the inner size and shape are selected in accordance with the facial features of the wearer to ensure maximum visual acuity and comfort. The mounting member consists of a long slender mounting pin having a threaded end portion arranged to engage an internally threaded hole in the nose piece. The mounting member is rotatably mounted on the eyeglasses frame and raises or lowers the nose piece in response to rotational motion imparted to the mounting member. The guide way is comprised of a track on the eyeglasses frame and a groove cut in the nose piece. Alternate embodiments of the present invention showing different ways for interchangeably mounting the nose piece to the cross piece of the eyeglasses frame are also disclosed herein by this invention.
