  • Publication number: 20020126376
    Abstract: An optical accessory of the type used by medical professionals is coupled to a clip-on mount, enabling the assembly to be used with ordinary eyeglass frames. The assembly may be used with specialized frames, in which case the clip-on mount may be removed for a more permanent mounting of the assembly directly to the bridge area of the eyeglass frames. In different implementations, optical accessories in the form of ocular loupes, head lamps, and miniaturized video cameras may be accommodated according to the invention.

  • Patent number: 6439714
    Abstract: An adjusting device for use with a pair of telescopic oculars allows independent rotation of each ocular to correct vertical misalignment between the lines of sight of the oculars. The oculars are part of an optical mounting assembly that includes a housing in which two slide bars are mounted. The oculars are mounted on the slide bars through bosses and mounting screws. An adjusting set screw is threaded through a hole on each slide bar so that it can push against the boss. By tightening or loosening the set screw, the line of sight of each ocular can be adjusted vertically, so that vertical misalignment between the lines of sight is effectively controlled.

  • Patent number: 6340228
    Abstract: A formable nose pad distributes the weight of eyeglasses and accessories supported by the eyeglass frames over a large area of the wearer's nose. The nose pad has two inner tabs that can be formed to fit the wearer's nose, outer tabs that can be formed to fit the undersides of the eyeglass lenses and a flange through which the nose pad is attached to the eyeglass bridge. Slotted screw holes on the flange allow for height adjustment to fit the height of the wearer's nose.

  • Patent number: 6333814
    Abstract: An improved ocular mounting assembly having a pair of ocular support arms which can be extended by sliding out of a box-section assembly housing for supporting a pair of ocular devices attached to the ends of the support arms. The improvement is a pair of stabilizers disposed inside the assembly housing and providing stability against rotational motion when the arms are extended. In one embodiment, the stabilizers are interference-fitted balls, retained in position by retainer holes in the assembly housing, and receding into recess cut-outs at the end of the support arms when the arms are fully retracted. In an alternate embodiment, the stabilizers are L-shaped, and can be either an integral part of the housing or bonded to it with adhesive.
