  • Patent number: 5682909
    Abstract: A hair clip includes a base plate (1) secured to an ornamental cover and a pair of hooking arms (13) extending from the base plate, in which each arm has an extension protruding from an outer edge at the base portion of the arm. The extensions (13c) come into a sliding contact with an engaging part (4b) of a hair retainer (4) when it is moved towards its closed position. A shackling member (15) is provided for holding the hooking arms (13) at their overlapping position even after the arms have been unlatched. The hair clip further has a restoring member (14) which urges the shackling member (15) to return to its another position where the arms are freed, when the hair retainer (4) is opened such that the engaging part (4b) can no longer be latched by the hooking arms (13). Such a mechanism makes easier the unlatching of the hair clip, which is simple in structure and easy to manufacture and assemble.
