Patent number: 5664591Abstract: A hair clip includes a first jaw operable by a first opening lever and hinged to a second jaw operable by a second opening lever. The hinge is provided by perforated lugs respectively projecting beyond inside surfaces of intermediate connecting areas between the levers and the jaws through which passes a connecting pin defining a transverse hinge axis. Two open annular springs disposed coaxially around the hinge axis pass through corresponding openings in the levers and bear in corresponding housings on outside surfaces of the jaws. The annular springs cover the perforated lugs. A tubular member covers the connecting pin between the two sets of perforated lugs. The resulting clip has a posterior side of considerably improved esthetic appearance.Type: GrantFiled: February 26, 1996Date of Patent: September 9, 1997Assignee: C.S.P.
