Abstract
The bracelet clasp is of the unfolding buckle type comprising a base (1) and two strips (2, 4) capable of folding down onto the base. A cover (10) held by a push button (12) maintains the clasp in a closed position. The clasp comprises means (13) for the instantaneous raising of the cover (10) when pressure is exerted on the push button (12) to open the clasp. This device avoids a notch locking device which leads to a laborious manoeuvre for opening the clasp. Incidentally, the strands (8, 9) of the bracelet are hinged onto the strips (2, 4) which allows the bracelet to be presented flat.
Claims9
A bracelet clasp of the type with an unfolding buckle comprising a base, at least one first strip capable of folding down onto the base, the base and the first strip being attached to each other by one of their ends by means of a first hinge, the other end of the first strip having means for fixing a first strand of the bracelet, a cover locking the first strip in a folded down position on the base, said cover being mounted on said base by means of a hinge so as to effect lateral rocking with respect to the longitudinal direction of the bracelet, and a push button mounted in the base to lock said cover onto said base, wherein said clasp comprises means for the instantaneous raising of said cover from said base, without manual intervention, when pressure is manually exerted on the push button to unlock the cover from said base.
