ABSTRACT:
A pin assembly for use in securing lenses within the frames of eyeglasses is described. The assembly includes a pin having a head and a barrel and further includes a securing ring. The securing ring has a channel therethrough which includes a series of projections. An additional series of projections are formed on the barrel of the pin. Thus, when the pin is mounted within the frame of the glasses, the securing means is placed over the barrel so that the projections within the securing ring and the projections on the barrel cooperatively interact to permanently secure the pin assembly into the eyeglasses frame. This also insures that the lens is permanently mounted within the eyeglasses frame. The projections on the barrel of the pin and within the securing ring are oriented such that the user can slide the ring onto the barrel of the pin but can not remove the ring once the projections come in contact with each other.
