Abstract
A clasp equipped with an external shell (1), an internal thrust spring (2) and of a rotating lever (3) having a protrusion shaped activation button (8) to allow the user to act upon it with a pressing action to determine its opened position. The external shell (1) is shaped like a hooking bracket on the first end (4), while towards its middle section it is equipped with an ample internal lodging space (5) and on the second end it is shaped like a hook (6). The rotating lever (3) is fixed like a fulcrum inside the external shell (1) from one of its ends while the other end is shaped like an arm (9) to interact with the end of the external shell (1) shaped like a hook (6) to obtain the closed position of the clasp.
Claims3
A parrot clasp with an opening button, used to join chains in the production of ornamental necklaces and bracelets, comprising an external shell (1), an internal thrust spring (2), a rotating lever (3), a fulcrum (10) wherein the thrust spring (2) is placed around the fulcrum on which the lever rotates, with the external shell shaped like a bracket on a first end (4) through which a hooking point is created, on its central part is equipped with an ample internal lodging space (5), and shaped like a hook on a second end (6), an opening (7), at least on the side where the second end (6) is directed, from where a protruding activation point of the rotating lever (3) emerges, said clasp characterized so that the rotating lever (3) is equipped with a protrusion (8) shaped like a button, wherein said protrusion (8) is sized to allow its wider head to hit onto the side of the external shell (1) when the rotating lever (3) reaches an open position and wherein said wider head is symmetric with respect to a median plane of the rotating lever (3).
