Definitions
- the present invention relates to a safety device for a buckle (chain, bracelet, necklace, handle, etc.) in jewelry and leather goods.
- the closing of a loop is traditionally resolved by a carabiner comprising a split ring, but this split ring is never mechanically closed but simply obstructed or closed by bringing its ends together.
- Plate 1 It is essentially composed (Plate 1) of a frame (1) of oblong, hollow shape, carrying, in one embodiment, two axes of revolution serving as pivots receiving for one (P1) located inside the frame a trigger (2) returned by a spring (3), the other (P2) located at the periphery of the frame a rocker (4).
- the hollow of the frame is closed by a plate (5) which is secured to it.
- the trigger and the rocker move in rotation in the same plane of the thickness of the hollow of the frame, both according to arcs limited for each of the locking position (fig. 1) to that of full opening (fig. 2).
- the trigger incorporates three functions: a male primary lock function provided by a bolt (6) which is housed in the recess (7) of the free end of the U of the rocker, a lock function secondary provided by a female bolt (8) coming to receive the bolt (9) of the heel of the rocker, a function of unlocking of the scale using a button (10) projecting from the frame beyond the heel of the scale.
- the bolt (6) Passing from opening to closing, the bolt (6) is threaded into the recess (7) of the free end of the U of the rocker at the same time as the male bolt (7) of the heel of the rocker engages in the female element (8) of the trigger (fig. 1).
- a spring system (1 1) ensures the trigger a rest position in locked closure.
- the scale and the frame then form a mechanically closed ring whose solidity is almost limited only by the pure tensile strength of the material or materials used.
- the closure plate (5) can usefully, and at a lower cost, include personalization (trade name and / or decor) as well as the frame. Both the frame, the rocker and the cover can easily take on personalized shapes, or even follow registered models, specific to each incorporator. All or part of the constituent parts can be coated with a finishing material.
- the device can easily be made of any metal or alloy, precious or not, by a conventional process (lost wax, sintering, stamping ...) or modern: injection of plasticized powder under pressure plus cooking (“M.I.M.”) for example.
- the spring (3) is a pin spring with straight segments (Fig. 1).
- the male latch of the primary trigger lock comprises a chamfer (1 1) ensuring its automatic entry into the recess of the free end of the rocker and therefore closing the ring and locking the rocker in one hand.
- the frame has a third axis of revolution (1 2) serving as a pivot for a lever (1 3) integrating along the body of the frame until the opening of the trigger is blocked. Incidentally, it can also serve as a support for the closure plate (5).
- the frame is linked to the loop by direct connection (welding %) or by articulation (hinge %) or by a swivel system avoiding any defect in torsion and falling.
- the trigger integrates with the heel of the rocker a fourth function: the device becomes bistable, either full opening or locking, by replacing the female locking element with a double male system in opposition.
- the two faces (B1) and (B2) of the heel of the rocker then oppose respectively the two faces
- (G1) and (G2) of the heel of the trigger The shape of these two heels, rocker side and trigger side, preferably triangular allows however, the slight change in force from the wide open position to the locked position, but not the reverse, by the play of curvatures: the wide open position is obtained by the concave torque on the convex trigger side on the rocker side, while the locked position is obtained by the convex torque on the concave trigger side on the rocker side.
- the device according to the invention is particularly intended as a buckle clasp, whether it is a chain, a bracelet or a necklace of jewelry, a handle for leather goods.
