Embodiment Construction

[0020] figure 1 and 2 is a perspective view of a bracelet clasp comprising a first rigid arm 1 provided with two side portions 4a and 4b. One end 5 of the arm is arranged to receive a bracelet joint and has the form of a bridge connecting the two side parts. The other ends 20 of the side portions 4a and 4b are traversed by a mandrel 22 about which a first end 21 of the second deployment arm 2 is hinged. In the vicinity of this hinge, it can be observed that the side parts are joined by a bridge 23 which ensures, on the one hand, a good level of rigidity for the first arm 1 and, on the other hand, a as a stop for the second arm. The first and second rods 11a and 11b extend from the first end 21 of the second arm 2 . The rod has free ends 10a and 10b through which a mandrel 61 passes. The cover 3 is hinged about this spindle 61 and is provided with first and second flaps 50 and 51 having holes 80 for receiving lugs which are another The starting point of a link link. figu...

Abstract

The clasp has rigid and unfolding arms hinged to each other and formed by metal injection molding. A locking mechanism is formed of hooks (55, 57) to maintain the coupling of the unfolding arm to the rigid arm when pressure is not simultaneously exerted on right and left push-pieces (15a, 15b). A safety device is formed of extended portions (72, 73) to prevent lateral movement of a cover (3) from causing unlocking of the clasp when pressure is simultaneously exerted on one of the push-pieces and on a cover flap (51) arranged opposite the push-piece, in respective directions (A, B). The cover is made of cut and folded metal.

Description

technical field [0001] The invention relates to a bracelet clasp comprising at least two arms hinged to each other, a first rigid arm provided with two side parts, one end of said first arm is attached to a bracelet joint, the other of which is Hinged at one end to a first end of a second deployment arm from which first and second rods extend, the free ends of the rods traversing a mandrel about which the cover is hinged , the cover is provided with first and second baffles, another bracelet joint is attached to the first and second baffles, and the first and second button members are integrally provided with the first and second levers or fixed to said first and second rods and placed before the position where said mandrel traverses said rods, and said bracelet clasp further comprises a locking mechanism arranged so that when pressure is not simultaneously applied to The second arm remains coupled or coupled to the first arm while the two button members are on.
