Publication number: 20140159995Abstract: A HMD includes a pair of temple arms having spring steel that wraps around the head to provide long axis compression. The spring steel arms produce a compressive force along the long axis of the head that counters the gravitational force of a weight positioned at the forehead. The weight is supported by the long axis compression, rather than resting on the nose, ears or the top of the head. The front to back, long axis compressive force frees the head from all but the smallest amount of paraphernalia and allows for the weight to be worn in a way that is comfortable and non-intrusive. The spring steel temple arms are over bent inward well beyond the smallest size head and is used with a spine material that limits how far the temple arms can bend inward. An interface layer is also attached to provide comfort to the head.Type: ApplicationFiled: December 12, 2012Publication date: June 12, 2014Inventors: Aditha May Adams, Joel B.

Patent number: 4161060Abstract: Two metallic half-moulds are produced from a prototype. The half-moulds have complementary mould faces which abut when the mould is closed, and moulding surfaces formed with annular rim depressions joined by a bridge cavity, each rim depression bordering a support surface for a false lens. A webbed frame front is moulded, false lenses are cut from that moulded front, and the mould faces which abut are set-back by a total amount corresponding to the shrinkage of the false lenses, so that the false lenses are gripped between the support surfaces and shape lens bezels in the rims when a frame front is moulded.Type: GrantFiled: December 1, 1977Date of Patent: July 17, 1979Assignee: Essilor International (Cie Generale d'Optique)Inventors: William Lenne, Jean F.

Patent number: 4078283Abstract: A method for making eyeglass frames from thermoplastic material and the like comprising the steps of drilling four holes in the blank and placing the blank on a first fixture having two locating dowels and two expandable pins. The external frame contour is then milled and all necessary contours are milled on the front, rear, sides and ends of the frame, reversing the frame on the fixture as necessary. Finally, the frame is removed from the fixture and placed in a second fixture which engages and holds the frame externally. Lense openings and lense grooves in the walls thereof are thereafter machined.Type: GrantFiled: September 7, 1976Date of Patent: March 14, 1978Inventor: Jacques Choquette
